The trend of increasing the number of floors of private houses makes it necessary to solve the problem associated with the construction of floors. Level of modern construction technologies allows you not to be tied to certain conditions that are associated with the configuration and size of the premises of the house. This expands the possibilities for implementing plans and facilitates the work. Before you start building floors, you need to thoroughly understand how this is done. In this article we will tell you in detail how and from what to make floors between floors.

Basic requirements for floors between floors

Overlap is structural element building, which divides the building in a horizontal plane to form floors, and also separates them from the attic and basement. The share of costs for the construction of this structure is about 20% of the construction estimate. The ceiling is a critical structure, so at the design stage you should adhere to the basic requirements that apply to them:

1. Strength indicators must be at a level that allows them to withstand the load consisting of their own weight and the mass of building elements, objects and people. The strength of the floor increases with decreasing level of its location.
2. Rigidity parameters are directly dependent on the strength and width of the structure. For wooden structures, bending is allowed within 0.5-0.7% of their width, for steel beams - 0.25%.
3. The ceiling must provide sufficient sound insulation so that the noise level is within the limits sanitary standards. Improving this indicator is achieved by increasing the tightness of the joints.
4. The structure must have sufficient thermal insulation. If it is located between rooms with a temperature difference of more than 10 degrees Celsius, additional heat conservation measures must be implemented.
5. To achieve the required fire safety, the floor material must have a certain fire resistance. This concept refers to the degree of protection of premises from exposure to fire over a certain period of time.
6. The combination of mass and thickness of the structure must be optimal.

How are floors classified?

Depending on the level at which the ceilings are located, the requirements for them differ.

Overlap happens:

Interfloor ceilings: manufacturing options

In construction, there is a wide variety of solutions for organizing floors. They can be:

1. Beamless: prefabricated, monolithic and prefabricated-monolithic.
   
2. Beam: wooden, metal, reinforced concrete.
3. Wooden.
   Wooden floors

   This design is the most common in construction country houses. This is due to the possibility of creating the ceiling yourself. In addition, the material is affordable and has good sound and heat insulation properties.

4. Metal.
   This flooring option is usually used when organizing a plinth and basement. Metal constructions have high reliability and long service life, as well as their dimensions are smaller with the same load-bearing capacity.
   Metal products do not have sufficient thermal insulation and are susceptible to corrosion. The structure can be constructed from channels or I-beams, which are laid at a distance of 500-1500 mm from each other. They install reinforced concrete slabs of small standard sizes.
5. Reinforced concrete.
   The use of this option necessitates the use of lifting equipment, since the mass structural elements significant. In addition, the foundation is subject to heavy loads, which should be taken into account during design.
   Reinforced concrete floors

   The sound and thermal insulation indicators of the material are at an average level; reinforced concrete is difficult to process and has increased labor costs during installation.

6. Coffered, arched and hipped.
   Coffered and tent-type ceilings are a type of ribbed panels. They are used in the construction of facilities with big sizes, with complex architectural forms. Such floor structures are not relevant for the construction of private houses, as are arched floors.

Overlapping on wooden beams: features

The construction of interfloor slabs made of wood has a number of advantages:

• the design is simple to implement, it can be done with my own hands. Its installation does not take much time. The cost of work is significantly reduced due to the absence of the need to use special equipment, and activities for lifting and moving material can be carried out with one or two assistants;
• availability of wood. Used to make beams conifers trees that are widespread;
• relatively low weight, which makes it possible to significantly reduce the weight of the structure as a whole. Thus, construction costs are reduced;
• ease of installation of sound insulation improves the comfort of living in the house;
• wooden structures have a lower cost, which overall results in significant cost savings;
• the speed of creating a floor is comparable to the installation of floor slabs and is carried out in a day. In this case, a truck crane is not needed.

To the disadvantages wooden floors can be attributed:

• the existing length limitation (4.5 m) does not make it possible to construct floors over longer rooms without additional support;
• high fire hazard of wood requires special processing details;
• the tree is exposed to a number of biological factors, which is prevented by appropriate processing;
• relatively low strength.

Monolithic ceiling on corrugated sheets: what to look for

The difference between creating a ceiling using corrugated sheets and concrete is the fact that in the first case, special formwork is not required, and as a result they have a finished ceiling. In addition, the technology using corrugated sheets does not require finishing or modification.

The profiled configuration of the material creates the necessary strength and rigidity of the floor, thereby reducing the need for reinforcement and concrete. This is possible due to the fact that the solution fills only the voids of the ribs, and does not occupy the entire surface of the sheet.

To create such an overlap, it is important to use exclusively sheets intended for roofing.
The essence of the technology is to use corrugated sheeting as formwork, which is not dismantled after pouring concrete. The resulting structure has a special structure consisting of metal columns, beams, and joists as load-bearing supports. As a result, the load is redistributed from the floor to the supports, while the walls are not loaded. This design solution makes it possible to construct lightweight walls.

In addition, the organization of the support system allows, instead of expensive strip foundation use a glass type support. This will significantly reduce construction costs.

Covering with slabs between the first and second floors: reinforced concrete

Slabs made of reinforced concrete are widely used. According to some parameters, when compared with the monolithic design of the floor between the first and second floors, they have better performance.

The organization of such an overlap requires a strong foundation and involves the construction of walls from durable materials. As a rule, floor slabs are used for high-rise buildings.

Structures made from reinforced concrete slabs are reliable, durable and long term operation. The amount of loads that concrete can withstand is colossal. It is characterized by the property of increasing over time strength characteristics. In addition, the material fully meets the requirements for heat and sound insulation, and also has sufficient fire safety. The process of installing slab floors does not require much time using special equipment and is not complicated.

The main disadvantages of reinforced concrete products include their significant mass and the need to use special equipment for installation. In addition, such floors require the creation of screeds so that the load on them is uniform.

With all the shortcomings reinforced concrete slabs floors are successfully used in the construction of private houses.

Planning construction country cottage, the owner has to solve the difficult issue of choosing floors. Some contractors advise him to use reinforced concrete panels, others insist on using it as a cover wooden beams.

We decided to help newbies get out of a difficult situation. In our article you will find an overview of the advantages and disadvantages of wooden interfloor ceilings.

Useful tips for installing them and important nuances doing this work will also not be superfluous. We hope that the information received will be useful to you at the construction site and will help you avoid serious mistakes.

There is a stereotype in the minds of citizens according to which panels from precast concrete- only Possible Solution for any building. It is not difficult to overcome it.

It is enough to list the advantages of wooden beam floors:

• Minimum cost (1 m3 of timber is several times cheaper than 1 m3 of hollow-core panels);
• The load on the walls is 2-3 times less than from the panels. This allows you to significantly reduce the consumption of reinforcement and concrete when constructing the foundation;
• On short spans (up to 4 meters), wooden beams can be laid manually using simple devices (a winch or a lifting block). Installing heavy slabs without a powerful crane is an unrealistic task;
• Low labor intensity and high speed of work (compared to pouring a monolithic reinforced concrete floor);
• Environmental friendliness (used in concrete granite gravel, the radiation background of which can significantly exceed the norm).

As you know, there are no advantages without disadvantages. Wood floors have few of them:

• Increased deformability. It manifests itself in the effect of vibration when walking and the formation of cracks at the junction of plasterboard partitions;
• Low fire resistance (without special impregnation);
• Relatively short length (does not exceed 6 meters). For reinforced concrete panels it reaches 7.2 meters.

Among the disadvantages of these structures, some authors of feature articles include the formation of cracks in the ceiling plaster and poor insulation of impact noise. However, with a competent approach to installation, these two problems can be solved simply and reliably. To do this, a series of less thick beams are laid below the load-bearing beams, specially designed for lining the ceiling (plasterboard, OSB, lining, board).

The backing beam, like the main beam, is placed on the wall, but lower, and the ceiling lining is attached to it. This solution is not found often, although it is competent and its history goes back more than one century; in addition to cutting off structural noise from the second floor, this option eliminates cracks in the ceiling. They appear when a beam serves as a support for the floor of the second floor and at the same time the ceiling of the first floor is attached to it. Vibration and shock loads cause cracks in the finish.

Areas of application and calculation of wooden floors

• in buildings constructed of wood (frame and log);
• V country houses, designed for summer operation;
• V outbuildings(barns, bathhouses, workshops);
• in prefabricated prefabricated houses.

In addition to the listed options, wooden structures for interfloor ceilings can be used in cottages intended for year-round use. Only in this case you need to use the two-row beam installation system, which we described above.

We do not recommend selecting the section of timber according to the principle “the thicker the better”. Eat simple technique calculations taken from building regulations.

According to it, the height of the wooden beam must be at least 1/25 of the size of the span being covered. For example, with a 4-meter distance between the walls, you need to buy a saw log with a section height (H) of no less than 400/25 = 16 cm with a thickness (S) of 12 cm. To create a safety margin, the found parameters can be increased by 2-3 cm .

The second parameter that needs to be selected correctly is the number of beams. It depends on their pitch (the distance between the central axes). Knowing the cross-section of the beam and the size of the span, the step is determined from the table.

Table. Choosing beam spacing

The design load of 350-400 kg/m2 indicated in the table is the maximum for the second floor. If it is not residential, then its value will not exceed 250 kg/m2.

When planning the layout of the beams, you need to take into account that the two outer ones must deviate from the end walls by at least 5 cm. The remaining beams are distributed evenly across the walls (in accordance with the selected pitch).

Installation stages and features

Technologically, the installation of floors using wooden beams cannot be called complex. The main attention should be paid to the horizontal alignment of the beams and the quality of embedding their ends into the wall mass. You cannot simply lay the beams on the masonry and cover them with bricks. It is necessary to provide them with a reliable connection with the walls and to properly protect the wood from rotting.

Options for sealing beams depending on the masonry material, type of wall structures (external, internal, chimney) and methods of their fastening are shown in the figures.

The length of the supporting part of the beams in brick and block wall should be at least 16 cm (in wood 7-8 cm). If paired boards placed on edge are used instead of timber, they are embedded in the masonry at least 10 cm deep.

The side parts of the beams in contact with the wall are wrapped with 2 layers of glassine or 1 layer of roofing felt. Experienced craftsmen cut the ends of the beams at an angle (60-70°) and leave them uninsulated, not forgetting to treat them with an antiseptic compound evenly with the rest of the part. This ensures the “breathing” of wood wrapped in waterproofing.

When installing the ceiling, small gaps (3-5 cm) are left on the sides of each beam, filled with mineral wool or tow. A heat insulator is also placed in the space between the end of each beam and the wall. This eliminates the “cold bridge” that occurs by reducing the thickness of the masonry.

When installing floors in walls made of aerated concrete and arbolite blocks, it is recommended to use an open seal. In this case, the ends of the beams are also cut at an angle, antiseptic and covered with roofing felt and mastic, leaving the ends free.

The outer wall of the nest is insulated with felt or mineral wool and a box made from pieces of antiseptic board is inserted into it. Its height is chosen such that an air gap (2-3 cm) is formed above the beam. Through it, water vapor accumulating in the wood will escape into the room in the baseboard area. This solution protects supporting part beams from rotting.

In practice, developers most often use a simpler method of sealing without the use of insulation and a wooden frame, covering the logs with cuttings of blocks or simply a raster.

The floor beams rest on, which is used to increase the spatial rigidity of the block masonry.

Beams are embedded in the internal load-bearing walls in a closed way. To increase the rigidity of the floor, they are connected through three to each other with steel anchor plates.

The section of the beam adjacent to the smoke duct is insulated with asbestos or other non-combustible material. The main protection against fire here is a brick cut (thickening of the pipe masonry) 25 cm thick.

IN wooden houses Installation of beam floors is carried out in two ways:

• Cutting into log crowns;
• Through a steel shaped plate (chair), fixed to the wall using threaded rods.

Installation of ceilings by cutting into walls

Option to install beams on “chairs”

If the top floor or attic space will not be residential (heated), then it is necessary to insulate the wooden floors. To do this, insulation (mineral wool, ecowool) is placed in the space between the beams, having previously spread a layer of vapor barrier along the ceiling lining.

Polystyrene foam should not be used for this work for three reasons:

• It does not allow water vapor to pass through, and the wood underneath it rots;
• Does not isolate impact noise;
• It is problematic from an environmental point of view.

The design of the insulated floor is shown in the diagram.

The insulation of the ceiling of the first (ground) floor is carried out in the same way. The difference between them is that it is quite difficult to hem beams from below from a shallow underground. In this case, builders act differently. They tack a cranial block (5x5 cm) to the side edges of the beams. An antiseptic boardwalk. It serves as a support for slab insulation, placed in the spaces between the bars. A vapor barrier is placed under the mineral wool. A vapor barrier is also laid on top of the beams. After this, logs are attached to them and the finished floor is installed on them.

The mineral wool slab should be placed between the beams as tightly as possible to prevent the floor from blowing through. For better insulation, all insulation joints are treated with polyurethane foam.

Control of the horizontal installation of the beams is carried out using a bubble level laid on a flat, long board. For leveling, use cutting boards, protected bitumen mastic. They are placed under the ends of the beams.

Vapor barrier sheets should be laid with an overlap of at least 10 cm and all joints should be taped with construction tape.

To reduce impact noise, before installing the second floor floor joists, soundproofing tape 5 mm thick is laid along the beams. A waterproofing film is placed under the joists only if the second-level room is residential. It will protect the insulation from water entering when washing the floor. The technology for its installation is similar to laying a vapor barrier.

The final stage of installing a wooden floor is the installation of a subfloor made of boards, plywood or OSB boards using self-tapping screws. After completing this work, lay fine coating from laminate, linoleum, parquet and perform finishing ceiling.

For execution interfloor covering In private housing construction, as a rule, one of four options is used:

Each of these methods has its own advantages and disadvantages. Let's look at each of them in more detail and try to choose the most suitable option for us.

Before I begin to express my opinion on each flooring option, I want to draw your attention to the fact that any of them is better done using a reinforced belt. Firstly, a reinforced belt will give your structure an additional margin of strength, and secondly, it will more evenly transfer the load from the floor to the walls.

It is performed in buildings with walls made of almost any material, but I can say that this type of flooring is ideal for walls made of SIP panels. I can’t say that this method is less labor-intensive than the others, rather the opposite. The meaning of this design is as follows: wooden beams with a cross-section of 100x200mm are laid against load-bearing walls, the beams are laid on a side with a length of 100mm, the distance between the beams is from 0.60m.

On many sites you can find calculations of floor loads, distances and beam section which must be applied depending on the span length (distance between load-bearing walls). On this occasion, I would only like to say the following: Don’t bother yourself. All these troubles are drawn from SNiPs and GOSTs for construction, written back in the last century under standard construction. Think for yourself, most lumber is made 4.50 m long, the section of timber is 200x200mm, half-timber is 200x100mm. Finding or ordering lumber with other parameters is quite difficult and costly. So why do you need it? Do you have extra money? Give the money to your wife, she will find a worthy use for it ;-). It turns out that it is better to think in advance about what material the ceiling will be made of and design the premises with the appropriate geometric parameters

, so as not to run around the neighborhood later, looking for timber 5.50 m long and 300x150 mm in cross section. Based on all of the above, we return to the essence of our question: we accept beams with a cross-section of 200x100 mm, the distance between them is 0.60 m and end the puzzle here. It is advisable to use larch timber for the ceiling; this type of wood resists rotting very well compared to other types of wood. After installation, they are attached to the beams

cranial bars

with a section of 40x50mm. They serve as support for roll-up shields. The bars can be fastened with both nails and screws; the main requirement is reliability. The bars must bear the weight of the roll-up panels and materials that act as sound insulation. Next, the roll-up shields are laid. The rolling board is boards made of low-grade wood, laid perpendicular to the beams on cranial bars. In our case, it is quite possible to use substandard wood, its thickness is 20mm, width 180-250mm. Before laying, the boards for the rolling shield must be antiseptic and treated with fire retardants. There should be a gap of 8-10mm between the roll shield and the floor beam. The gap between the boards of the roll shield itself should be minimal.

According to the roll-up shield, I advise you to lay plastic film in one layer with an overlap on

floor beams

Prefabricated reinforced concrete interfloor slab

Just as in the case of the basement interfloor ceiling, it is very labor intensive. Simply put, it will be quite difficult for you to make it yourself. This is due to the fact that this requires the installation of formwork, large quantity supports, performing serious reinforcement cage and high-quality concrete mixture. Based on all of the above, I strongly recommend that you follow

interfloor covering on beams or slabs. If you have the opportunity to use metal I-beams, then it will be simply gorgeous. But for lack of anything better, I advise everyone else to accept leaf beams with a cross-section of 200 x 100mm. This method is the most optimal in terms of price/quality. Currently this type

ceilings are becoming quite popular. The design is such that it allows for overlapping, both on the base and between floors. The use of small hollow blocks allows you to make floors in buildings

with a complex geometric shape (the use of bay windows and other architectural delights). The essence

this method

quite simple: Hollow ones are laid:

metal beams

Hollow blocks are laid on beams

This entire structure is filled with concrete

It is very important that the concrete has as much adhesion to the beams as possible. Well, it seems simple.

This type of floors has a number of advantages over prefabricated and

monolithic floors

The construction process requires less labor (3-4 people)

the ceiling is lighter (20% lighter than a prefabricated one, and 50% lighter than a monolithic one)

Significantly reduced cost (up to 30%) No construction equipment required (power tools are sufficient) No leveling screed required It's quite simple. As soon as I understand this type of overlap in more detail, I will immediately write a detailed article on this topic. no more than 105 kilograms per square meter. For interfloor ceilings, this value increases to 210 kilograms per square meter. The floors between floors in a private house must be strong, they should not bend under the influence of loads; the permissible bend value for attic floors is 1/200, while in the case of spans between floors this value should be 1/250.

Basic requirements for floors

During the construction of floors, a sufficient degree of noise insulation should be ensured; the value is established by design standards. To do this, you should close the gaps at the places where the material joins; only in this case, sounds from neighboring rooms will spread minimally. Floors that separate rooms with a certain temperature difference must meet thermal protection requirements. This indicates the need to use an additional layer of thermal insulation. Any structure, especially one made of wood, is not able to withstand prolonged exposure to fire. It should be remembered that each material is characterized by a certain fire resistance limit. For reinforced concrete floors it is 60 minutes, but if the structure is made of wood with backfill and has a plastered surface underneath, then the fire resistance will last 45 minutes. which are protected by a layer of plaster, can withstand flames for approximately 15 minutes. If there are wooden floors that were not protected with fireproof materials during the installation process, it should be taken into account that their fire resistance limit is even lower.

Types of floors

The ceilings between floors in a private house can be interfloor, basement, basement or attic. By constructive solution The load-bearing part of the floors can be beam or beamless. In the first case, the system consists of beams and infill. In the second, the structure is made of homogeneous elements such as panels or slabs.

Features of the beam floor

The ceilings between floors in a private house can be beams, while individual elements are located at equal distances from each other, and filling elements are laid on the beams. The latter act as a fence. Beams can be metal, reinforced concrete or wood.

Features of the construction of floors made of wooden beams

In the construction of private houses, in most cases they are used beam floors made of wood. For beams, there are restrictions on the span width; they can be used for attic floors or interfloor structures, in which the span width should be 5 meters. Such products are made from coniferous or hardwood, and on the upper side there is a flooring, which is the floor. The design of such a ceiling requires the presence of beams, a beating, a floor and thermal insulation material.

If you decide to build floors between floors in a private house with your own hands using wooden beams, you should know that the house can have a rectangular plan. In this case, it is necessary to block the spans in the direction along the short wall. To ensure that the ceiling does not sag under its own weight, its elements are laid at a certain distance. If it is necessary to build a 3x4 meter floor, you should use 6x20 beams, which are laid along a 3-meter wall. If the floor is interfloor, then the beams should be 1.25 meters apart from each other; in the case of an attic floor, the distance increases to 1.85 meters. This indicates that as the span width increases, the distance between the beams becomes larger.

Work technology

If you are laying floors between floors in a private house made of wood, then the elements are initially treated with an antiseptic. When they are supported on concrete or stone wall the ends are wrapped in two layers of roofing material, and the beam is inserted into the prepared nest. In this case, the element should not reach back wall by 3 centimeters, the end of the beam should be beveled. The remaining free space is filled with thermal insulation, which can be replaced with polyurethane foam.

On side faces beams are reinforced with 4x4 or 5x5 bars, which are called cranial bars. The roll from the wooden shields. The knurling plates are pressed tightly against each other and are attached to them using self-tapping screws. When overlaps are made between floors in a private house, it is recommended to review the photo in advance. This will allow you to understand that the design requires the installation of insulation. It will act as a noise-absorbing layer, and attic floor- thermal insulation function. The materials you can use are polystyrene foam, expanded clay, sawdust, mineral wool, shavings, straw, and wood foliage. After fixing the roll, thermal insulation is laid on top. A layer of roofing felt should first be laid between the beams, vapor barrier film or glassine, bending the material five centimeters onto the beams. Then comes the turn of laying a layer of thermal insulation.

Construction of a concrete floor

Concrete floors between floors in a private house may have in different forms. If we are talking about monolithic structures, then they are a solid slab, the thickness of which is equal to the limit from 8 to 12 centimeters. In this case, concrete grade M 200 is used, the slab itself rests on the weight of a square meter of such an overlap can be 490 kilograms if the thickness is 200 millimeters. Installation is carried out in several stages, the first is the installation of load-bearing beams in the prepared place, then the wooden formwork is arranged from unedged boards, and at the next stage 6 mm reinforcement is laid. On final stage concrete is being poured. The thickness of the floors between floors in a private house can be equal to the above-mentioned limit, however, it is also important to correctly construct the formwork, which is sometimes purchased in finished form. It consists of beams, plywood, and a tripod. If you use formwork made of aluminum or wooden beams, then the master will have the opportunity to build a ceiling of any configuration.

Conclusion

Floors between floors in a private house made of aerated concrete are usually made of wood, since the weight of the material at the base of the walls is not so large as to bear the loads of concrete.

/ How is an interfloor wooden floor created?

How is an interfloor wooden floor created?

During construction country house or a dacha, there is a need to erect interfloor ceilings. They can be made of different materials, mainly depending on what the house itself is being built from. However, most often, interfloor ceilings are constructed from wood, since this material is more accessible and much easier to work with.

Basic requirements for this element of construction

The most significant characteristic of an interfloor slab is its strength. In order for this part of the house structure to serve for a long time and not cause trouble to the owner, special calculations are made, according to which this structural element of the house is built.

In terms of strength, wooden elements installed every meter must withstand a load of 400 kilograms per square meter of area. To facilitate calculation and construction, there are verified sizes of beams that can withstand the specified weight:

• With a span length not exceeding 2.2 meters, beams with a cross section of 150x75 millimeters can withstand such a maximum load
• If the span is from 2.2 to 3.2 meters, the cross-section of the beam should be 175X100 millimeters
• For a span of 3.2 to 5 meters in length, the beam must have a cross-section of 225X150 millimeters

These dimensions of load-bearing elements are intended for the device residential second floors of the house. For attic spaces, and other floors that are not intended to be used as living space, the load on the area can be halved. Accordingly, beams can be taken with a smaller cross-section. Anyway, optimal ratio the height of the beam to its width will be 1.5 X 1.

Another ratio you can use is 1 to 24. This is a proportion that can be used if you know the length of the required span. Length must be 24 times greater than the height of the carrier wooden element designs. With a length of 600 centimeters, the height of the board that will be used as a carrier should be 600/24 ​​- 25 centimeters.

If the floors are made of wood, the calculation of the beams that make up its base is carried out not only on the strength of the entire structure, but also on its rigidity and thermal insulation characteristics. Sound permeability is also important, otherwise everything that happens on one floor of the house will be heard on the other.

If the building is made of brick, there are two possible ways to install beams - solid sealing and open. They differ in that with the second method, part of the load-bearing board will be visible from outside the buildings. For it, a through niche is provided. In this case, additional processing of the load-bearing elements will be required, protective equipment from environmental influences.

At frame construction, the boards that will make up the base of the floor and ceiling are laid on top of the frame. Specifically - on top harness. The requirements for the sections of boards will be the same in all cases.

When installing load-bearing parts of the structure, it is very important to monitor the level of their location relative to the horizon. All boards must be in the same plane. Their position must be constantly monitored. So that later, there will be no distortions.

Since all the floor beams discussed in this material are made of wood, their adjustment to required sizes It is done very simply - by sawing off. There is no need to throw away the sawn parts immediately. They can be useful just at the stage of installing load-bearing elements, as linings to position them at the desired level.

After installing all the load-bearing parts, you can begin installing the reel on the second floor and filing the ceiling on the first. Usually, top part This “pie” is made up of two layers – the “rough” floor and the “finished” floor. By finished floor, you can now lay the finishing coat.

The ceiling can be hemmed with the most different materials, including popular gypsum boards or chipboards. The finishing touches are already being done on them.

Conclusion

Of course, within the framework of a small material, give exact instructions How to assemble an interfloor floor from wood will not work. This is only an approximate story about how and in what order what will be done.

The exact procedure, and all the nuances in the construction of such structural elements of the house, must be studied in relation to the specific building and the materials from which it is made.
