What types of floors are used in wood concrete construction? How are they supported on a wall made of wood concrete blocks?
In houses made of arbolite blocks with low number of storeys, the use of various options interfloor ceilings. This:
- floors on wooden, reinforced concrete or steel beams;
- monolithic reinforced concrete floor;
- prefabricated reinforced concrete floor slabs;
- prefabricated monolithic floors.
How to support floors on wood concrete blocks?
The floor structures are based on a distribution belt, which serves to evenly distribute the load on the wall and prevent local chipping of the wall wood concrete blocks. It is recommended to make the armored belt from monolithic reinforced concrete.
If it is not necessary to reduce the influence of base deformation, then for arranging the distribution belt it is allowed to use brick belts- that is, three rows solid brick, reinforced with masonry mesh.
In internal load-bearing walls, an armored belt should be installed across the entire width of the wall.
Floor ends with outside buildings should be thermally insulated with a 10-15 centimeter layer of wood concrete. In this case, between the end of the slab and the block it is necessary to leave a gap of -1-2 cm and fill it polyurethane foam or mineral wool (or any other easily deformable insulation).
Wooden beams on wood concrete
Using wooden structures, the ends of the beams turn around roll waterproofing. TO monolithic armored belt beams are fastened with studs or anchor bolts, mounted before concreting, or galvanized metal corners.
Wooden beams rest on arbolite blocks at least 15 cm deep.
Installation of prefabricated reinforced concrete slabs
When using prefabricated reinforced concrete slabs, it is necessary to anchor the external walls to the floors. Bent reinforcing bars Ø8A240 are used - one side of the bar is laid along the wood concrete block, the other is attached to the mounting loop of the floor slab. Along the surface of the ceiling, the reinforcement is additionally protected with a layer of DSP. In addition, it is recommended to anchor the slabs together with metal brackets (reinforcing steel Ø8A240).
Monolithic reinforced concrete belt
The distribution belt must be made in one of the following ways:
- in formwork made of special wood concrete;
- with external formwork made of wood concrete 10-15 cm thick;
- belt across the entire width of the wall removable formwork(in this case, insulation of the armored belt is required to eliminate cold bridges).
A prefabricated monolithic ceiling is designed to divide a building into floors and soundproof rooms between each other. Wood concrete, foam concrete, and aerated concrete are used as filler materials. But now we will talk about wood concrete flooring.
Description
Innovations in construction technology are making the construction process easier. But the arrangement of interfloor ceilings has not undergone many changes. Arbolite flooring today is not a new product that is used in the construction of buildings. The installation of floors can be done without specialized equipment. Installation technologies in all countries do not differ from each other. Prefabricated monolithic floors (arbolite as a filler material) have a number of advantages.
Installation diagram of wood concrete floors: on formwork wooden boards, which are installed parallel to each other, wood concrete blocks are laid. Reinforcing mesh is laid on top of the blocks. The last stage of installation is concreting the entire structure.
Arbolite floor slabs consist of prestressed reinforcement, an arbolite layer and layers of concrete. In this way, they decided to reduce the consumption of concrete mixture and increase the load-bearing capacity of wood concrete slabs. The concrete mixture solution is prepared from cement grade M400 and higher, and wood concrete is taken not lower than class B 3.5.
Installation
Many construction companies They offer ready-made frames into which wood concrete blocks are placed. They are often ribbed floors consisting of reinforced concrete structures. The length of such products can reach 12 m, and the width - 100 mm. The step between these structures reaches 650 mm. Free space filled with wood concrete blocks. Wooden boards are laid under the frames, serving as a reference for placing block products. For structural rigidity, supports are installed every 2 m. Next, the arbolite floor slabs are reinforced reinforcement mesh made of metal wire with a diameter of 5 mm. On top of this entire structure is laid concrete mixture, which is compacted by a vibration compactor. The thickness of this layer is not less than 30 mm, but not more than 50 mm.
Instead of reinforced concrete beams Sometimes wooden I-beams are used. They are made from OSB boards. If you purchase ready-made beams, they do not require further processing. Wood concrete flooring over wooden beams is the cheapest option. It is lighter than reinforced concrete and has best performance thermal conductivity.
Wooden beams are characterized by their strength in bending and torsion. It is easy to calculate the beam parameters yourself. To do this, you need to take the ratio of height and width in the proportion 7:5. This will avoid deflections and deformations. To completely eliminate beam subsidence from the bottom wooden beam You should use an electric planer to remove a value that is equal to the maximum permissible deflection.
Installation of ceilings on wooden beams is no different from other options.
The boards are installed in increments of no more than 600 mm; when resting on the wall, the ends of the beams are wrapped with waterproofing. Next, wood concrete blocks or a solid wood concrete slab are laid. In the first case, the structure is reinforced and filled with concrete mixture. An arbolite slab does not need this.
Advantages
- Ability to plan complex Constructive decisions buildings. Prefabricated monolithic slabs make it possible to optimally cover structures with complex configurations. There is no need to start from the generally accepted sizes of slabs, lay them out and arrange monolithic areas.
- Monolithic flooring can withstand heavy loads. You can calculate this yourself. For the flooring, wood concrete blocks of class B 3.5 are used, which have a density of 800 kg/m3. Cement strainer takes on compressive forces, and the reinforcement takes on tensile forces. Together they have a density of more than 200 kg/m3.
- A prefabricated monolithic floor does not require the installation of a separate armored belt. Concreting a structure with beams, reinforcement and wood concrete in itself constitutes an armored belt. Concrete screed performs the same functions that a reinforced floor should perform: it protects the structure from cracks due to swelling of the soil.
- The weight and size of the structures allows one vehicle to transport up to 200 m2 of floors.
- Installation and arrangement of floors can be performed without using additional equipment. The weight of the structures allows all construction operations to be performed manually.
- Unlike reinforced concrete slabs, a monolithic arbolite floor requires less consumption of concrete and reinforcement.
- Wood concrete has high thermal insulation and sound insulation properties.
- Prefabricated monolithic floors are cheaper than other types of floors. And not only the material itself, but also the possibility of installation without expensive equipment also reduces construction costs.
- Possibility of making wood concrete floors with your own hands.
Flaws
Each material has its own disadvantages. Arbolite is very afraid of moisture. A one-time wetness does not threaten it, but constant exposure to precipitation destroys the material.
Flammability of wood concrete
Many manufacturers claim that the material does not burn, but at high temperatures the wood chips begin to smolder.
After a fire, the ceiling cannot be restored. Many manufacturers do not conscientiously fulfill all the requirements of technology during production. Insufficient amount of lime in wood concrete leads to rotting wood chips. Custom sizes blocks can also be considered disadvantages. There are deviations in height and width up to 2 cm.
A prefabricated monolithic arbolite floor must be carried out in accordance with all the rules of installation technology. Arbolite blocks may begin to rot inside such a ceiling. A concrete pouring hides the wood concrete, making it difficult to see this process until the floor begins to collapse.
Wood concrete houses
If the building design involves construction from wood concrete, then the question arises: what kind of floor to use?
Wooden interfloor ceilings in a house made of wood concrete can only be used if the wood is treated with special means.
This way the beams will not rot or collapse. It is also worth worrying about fire safety.
House made of wood concrete: how to cover the first floor? It is better to use lightweight materials that are light in weight but can withstand significant loads. There are ribbed wood concrete floor slabs with load-bearing side edges. They give the structure additional rigidity and stability.
ARBOLIT- is a building material, is a type lightweight concrete. The composition of the wood concrete includes M500 cement; water; wood chips of certain sizes, treated with lime, alumina sulfate, or simply aged for at least a month outdoors(chips should be at least 80-90% of the total volume of the block). Arbolite is made without the use of sand. Arbolite is widely used in Russia for the construction of houses, dachas, bathhouses, garages, but mainly in those regions where there is a lot of forest. After all, in order to produce 1 m3 of wood concrete, you need 1.3 m3 of dry wood chips of the sizes determined by GOST. That is why all the main production of wood concrete in Russia is located in regions rich in forests.
Arbolite is a large-porous material that provides excellent air exchange in rooms, thereby making the microclimate in the house very comfortable for living;
wood concrete density is 500-600 kg/m3, which allows saving on the foundation;
wood concrete has low thermal conductivity;
the strength of wood concrete B2 and excellent characteristics of tensile and bending strength make it possible to build houses with a height of 2-3 floors with a wall thickness of 30-40 cm without any problems. In this case, you can use both wooden and reinforced concrete floors;
large and convenient block sizes speed up the construction process and save money on paying workers;
despite the fact that wood concrete consists almost entirely of wood chips, it does not rot and is not susceptible to infection by microorganisms and fungi. Wood acquires such properties after processing, provided it is in a solution of high-grade cement and mineral additives.
wood concrete belongs to the class of fire-resistant materials and is able to withstand an open flame with a temperature of at least 1000°C for 45-90 minutes.
Wood concrete is resistant to impact and mechanical stress, and at the same time is easy to drill and saw, and easily holds fasteners.
The specific heat capacity of wood concrete is several times greater than that of brick, which is why in houses made of wood concrete summer heat It’s cool, and in the cold of winter, wood concrete walls can retain heat for a long time.
Wood concrete is manufactured in accordance with the current GOST 19222-84 and the Instructions for the design, manufacture and use of structures and products made of wood concrete (Approved by the resolution State Committee USSR for Construction Affairs dated May 4, 1982 No. 116).
History of wood concrete
Developed and standardized in the 60s. During the years of the USSR, more than 100 wood concrete plants were built.
Wood concrete production technology
For the manufacture of wood concrete and products made from it, it is used following materials:
* mineral binder (Portland cement, Portland cement with mineral additives, sulfate-resistant cement- except pozzolanic - according to GOST 10178 and GOST 22266 grades not lower than 300 - for thermal insulating wood concrete and 400 - for structural wood concrete);
* organic fillers (chopped wood from waste from logging, sawmilling and woodworking of coniferous (spruce, pine, fir) and deciduous (birch, aspen, beech, poplar) species, hemp and flax bonfire, chopped cotton stalks and chopped rice straw);
* additional substances (hardening accelerators, steam generator, plasticizers, steel corrosion inhibitors, etc.) according to GOST 24211;
* water according to GOST 23723.
Types of wood concrete
There are the following types of wood concrete - thermal insulation (density from 400 to 500 kg/m³) and structural (density from 500 to 850 kg/m³). It is used in the form of ready-made building blocks or slabs for the construction of self-supporting walls or internal partitions buildings, and also as a heat-insulating and sound-proofing material.
Characteristics
The thermal conductivity of wood concrete is 0.07-0.17 W/(m K). The most important characteristic wood concrete, like any building material, is the compressive strength. The compressive strength of wood concrete varies from M5-M10 for thermal insulation to M25-M50 and even up to M100 for structural.
Wood concrete has increased bending strength and absorbs sound waves quite well.
Wood concrete does not support combustion and is convenient for processing. Structural types have a high flexural strength and can restore their shape after temporarily exceeding the maximum load.
The disadvantages of wood concrete include reduced moisture resistance. The outer surface of wood concrete structures in contact with atmospheric moisture must have a protective finishing layer. It is advisable to maintain air humidity in rooms with wood concrete walls no higher than 75%.
Application of wood concrete
Arbolite is used for monolithic construction low-rise buildings for residential, commercial and industrial purposes, as well as in the form of blocks.
Questions and answers
How many blocks are needed for a bathhouse measuring 2x4 meters?
Approximate calculation for a 2x4 meter bath (according to external dimensions)
Perimeter of the building (2+4)x2= 12 meters, wall thickness 20 cm (block laid on edge)
With a wall height of 2.4 m from the base, 12x0.2x2.4 = 5.76 cubic meters. minus windows and doors.
With a wall height of 2.1 m from the base, 12x0.2x2.1 = 5.04 cubic meters. minus windows and doors.
What kind of solution is used to lay arbolite blocks?
The laying of arbolite blocks is carried out on cement-sand mixture(CPS). For greater plasticity, a certain amount of fluff lime can be added to the mixture. In order to avoid cold bridges, perlite can be added to the CPS during laying. In the same way, sawdust can be used instead of perlite, but it will require mineralization to neutralize sugars.
Is it possible to use wood concrete blocks as a foundation, or for the construction of a basement?
The use of wood concrete in the foundation is not recommended, not because it will not withstand the loads, but because the natural humidity of the earth is much higher natural humidity air, even during rain, secondly, this humidity is constant, and if there is also water inflow in the form of perched water or groundwater, then everything gets worse. Arbolite is a material with high water absorption, i.e. it will begin to absorb water from the soil, and constantly, accordingly the material will have high humidity. But when the humidity begins to differ greatly from the norm, the wood concrete’s thermal conductivity immediately increases and some other characteristics in the wall deteriorate. That is why it is not recommended for foundation. It is impossible to achieve such critical humidity values in a wall, even if you water it with a brassboil during the day; it will dry out overnight and release excess water into the atmosphere.
How tall can you build houses from wood concrete?
Arbolite is divided into structural and thermal insulation. As the name suggests, build buildings with load-bearing walls from wood concrete stands from structural wood concrete. The strength of M25 wood concrete blocks is sufficient for the construction of a building of 2.5 floors with floors made of hollow core slabs.
When building a house made of wood concrete, is it possible to use hollow core slabs as floors?
Can be used different kinds interfloor coverings, such as hollow core slabs, interfloor ceilings from expanded clay concrete, flooring on wooden beams, etc. To evenly distribute the load on the walls, it is recommended to make an armored belt between floors.
Is it possible to use a regular concrete mixer instead of a mixing station?
No, concrete mixers are not capable of producing high-quality wood concrete mixture. An example of what happens to a concrete mixer when mixing wood concrete can be seen in our production. At the same time, the mixing station not only mixes the mixture, but also additionally, by grinding the chips with an auger, brings it to the size required by GOST.
Wood concrete is more expensive than foam concrete, why is it better?
In addition to the best thermal insulation properties (70% on average), allowing you to avoid additional work In terms of insulation, arbolite blocks, when the load is exceeded, under shock loads, do not crack like foam concrete, but shrink, easily restoring their original shape after removing the load. This plasticity not only saves money during transportation and construction, but also protects the house from cracks during operation caused by shrinkage, temperature changes and other factors. In terms of earthquake resistance, houses made of wood concrete have almost no competitors. When building a house from wood concrete, unlike foam concrete, no reinforcement is required, which also significantly reduces the cost of work and materials. By summing up all construction costs, a house made of wood concrete is cheaper than a house made of foam concrete. Wood concrete has better frost resistance (the ability to withstand repeated freezing and thawing in a water-saturated state without signs of destruction or loss of strength), is more environmentally friendly, etc.
Is it possible to make wood concrete not from wood chips, but from sawdust?
It is possible, wood concrete made from sawdust is often called sawdust concrete. The characteristics of sawdust concrete are in many ways superior to other similar materials, although they are inferior to wood concrete made from wood chips.
Prefabricated monolith (ceiling)
Despite the development construction technologies in all directions, the design of floors still remains conservative, where traditional methods are used for the most part, stubbornly ignoring progressive solutions.
Installing floors is a labor-intensive and expensive task. IN construction estimates to a share concrete floors up to 20% of costs are reduced.
Prefabricated monolithic technology has been tested in practice in European countries for 20 years. The installation principle is the same, but this technology may involve the use of various materials.
1. Wooden formwork board
2. Vertical wooden support
3. Support wall of the building
4.5. Building wall block
6. Layer of concrete (300-500 mm)
7. Flat reinforcing structure connected in the form of a “mesh” (D-6 reinforcement, cell 200x200 mm.)
8. Block cassette / filler material
9. Volumetric reinforcing structure connected according to the “square” principle (D-12 reinforcement)
10. Concrete filling the interblock reinforced space
Prefabricated monolithic floors made of wood concrete are based on the generally accepted principles of prefabricated monolithic technology,
at the same time, they have elements of improvement aimed at simplifying installation and improving the quality of the final result.
1. Use of ready-made specialized metal structures made like “trusses” with additional stiffeners, is many times superior to volumetric reinforcing structures connected by workers on site, both in terms of speed and ease of installation, and in terms of strength characteristics. So one such structure, with a maximum length of 11.7 m, supported only at two extreme points, can easily support the weight of an adult without visible signs of deflection.
Advantages of SPAIT metal structures in comparison with common European analogues:
- light weight - the metal structure is 11.7 m long and weighs only 44 kg.
(for comparison, a 6-meter beam for a prefabricated monolith Teriva (Poland) weighs 72 kg, an 8-meter beam SerboCeramika (Serbia) weighs 68 kg.)
- ease of installation , transportation and use - It’s easy to give any design desired length both during transportation and already on site
(cut, weld, tie)
- installation speed - assembly of floors using ready-made metal structures significantly saves time and labor costs during installation
- reliability - metal structures, thanks to their design features(in the form of a "farm"), are lighter(due to using less
amount of metal) and, at the same time, more durable than the commonly used methods of knitting a volumetric reinforcing structure (in the shape of a “square”)
- efficiency
2. Use of arbolite block liners as a filler material allows you to create not only an incredibly light and strong floor, but also with the highest sound and thermal insulation properties, superior in their performance to well-known foreign analogues.
Characteristics of a frequently ribbed prefabricated monolithic floor
This is a frequently ribbed floor consisting of reinforced concrete structures (like trusses) and wood concrete blocks placed between them. The length of structures can reach 11.7 m, and the weight linear meter design is 3.8 kg. The floor structures are 100 mm wide. and are installed at a distance of 650 mm. from each other, and wood concrete blocks weighing about 7 kg are placed in this space. It is recommended to lay two polyethylene-coated boards (not edged) under the structures, which will serve as formwork for metal structures, as well as support points for placing wood concrete block liners. To ensure that the formwork boards do not sag during concreting of the floor, it is recommended to install support posts under them in several places (wooden supports are installed at a distance of 1 m to 2 m, depending on the thickness of the formwork board). Placed on top of structures and blocks metal grid, step 200x200 mm. (D rod 6 mm), and concreting is carried out, and the concrete mixture is compacted by vibration so that the ceiling structure is dense and has no pores. The concrete class is accepted to be no lower than B-25. Thickness monolithic concrete above the surface of the blocks is 30 mm, and the total ceiling height is 200 mm. After the concrete reaches 100% strength, the floor will be able to bear a load of up to 670 kg/sq.m. excluding their own weight, for comparison: reinforced concrete slabs have a similar indicator of 400 - 430 kg/sq.m., monolith 200 - 250 kg/sq.m.
Advantages of prefabricated monolithic floors:
Light weight(so, 1 sq.m. of flooring (including the top layer of concrete) weighs about 260 kg, while 1 sq.m. of reinforced concrete floor slab weighs about 380 kg. As a result, covering an area of 200 sq.m. with flooring , you get a weight saving - 24 tons!).
No need for a truck crane(the ceiling is assembled from individual small-sized elements. Characteristically, they are so light that a crane is not needed for their assembly - they are assembled manually. The ceiling elements assembled in this way can be mounted immediately after delivery to the construction site, attaching them to the walls and forming the necessary ceiling).
No screed needed to level the subfloor(when installing a heated floor, this is especially important, since it can be laid directly on the ceiling).
Floors can easily replace wooden and weakened floors in existing houses(small dimensions constituent elements overlaps allow you to work with it in hard to reach places).
Easy construction of floors in rooms with complex shapes- bay windows, ledges, openings (for stairs), etc.
Ensuring the load-bearing capacity of floors up to 1000 kg/sq.m. (taking into account your own weight).
The highest level of thermal protection and sound insulation in the building(the floors consist almost entirely of wood concrete blocks, which means they do not require either insulation or sound insulation).
Possibility to modify floor structures on the construction site: trim, shorten, give the required shape.
The use of truss structures for the installation of powerful load-bearing jumpers(2 structures are installed under the load-bearing partitions, which provides the necessary load-bearing capacity of the floor).
Saving by 20-25% in cost compared to floors made of reinforced concrete slabs and by 35-40% in comparison with a monolith.
Significant savings on delivery(due to small overall dimensions beam sections, it is possible to deliver to construction site up to 250 sq.m. SMP with one machine).
Thus, taking into account all the materials, labor and costs of using heavy equipment
arbolite prefabricated monolithic floors in one and a half times cheaper than floors made of reinforced concrete slabs
and almost in twice cheaper than monolithic floors.
Prefabricated monolith (foundation)
Conditional connection of the installation principles of the Frequently Ribbed Prefabricated Monolithic Floor and the principle of the Insulated Swedish Foundation Slab
made it possible to develop a warm foundation prefabricated monolithic slab(FSMP).
Similarities and advantages of FSMP in comparison with USP:
1. Reliable - the basis of the FSMP is made up of arbolite blocks, the strength characteristics of which significantly exceed the strength of expanded polystyrene.
The thickness of the FSMP is 30 cm. It can serve as a full-fledged foundation for buildings up to 3 floors high, an excellent foundation for houses made of any materials, from lightweight
frame to brick.
2. Excellent heat-saving properties - provides a material with excellent thermal insulation properties - wood concrete, evenly distributed over the entire surface
residential premises of the future building.
3. Highest sound-absorbing properties (dampers vibration well).
4. Integrated communications - the ability to connect all communication systems through the FSMP, including sewerage, water, electricity, water pipe laying
heating system (all that remains is to connect the plumbing and make the wiring).
5. Absolutely environmentally friendly - wood concrete (unlike EPPS, which is traditionally used as part of USP) is made from absolutely safe for
human materials (wood, cement, aluminum sulfate - used for drinking water purification)
5. Absence assembly seams - upon completion of installation, the surface of the FSMP has an absolutely smooth surface, suitable for use as a base for
finishing flooring(no finishing screed needed).
6. Absolute biostability - FSMP contains materials that are not susceptible to rotting or the effects of mold and mildew.
7. Fire safety - wood concrete is not flammable.
8. Simplicity and high speed installation - labor costs required for assembly and pouring 200 sq.m. surface FSMP is 3 people; period of FSMP assembly and filling
is 2-3 days.
9. No extensive excavation work.
10. No need to use heavy special equipment (except concrete pump).
11. Economical - the most expensive component of any foundation is concrete, the content of which in FSMP is reduced to a minimum (concrete savings for FSMP will be
about 20-30% compared to the volume of concrete required for pouring strip foundation; at the same time, the FSMP is not only the foundation, but at the same time
full floor covering).
Algorithm of work when installing FSMP:
1) Excavation- the top fertile layer of soil is removed, while the bottom of the pit must be leveled to the horizon.
2) Geotextile flooring- it copes well with the function of a separating layer. During operation it does not rot or collapse.
3) Construction of a sand cushion- consists of filling a sand cushion and compacting it. It is advisable to press wet sand in layers to achieve maximum cushion density. The thickness of the sand layer is about 15 cm.
4) Installation drainage system and laying communications(water, sewerage, electricity) - to lay a sewerage system, it is necessary to follow the sequence: compaction of a sand bed, excavation of sand for laying a sewer line, backfilling of sand, spilling it, repeated general compaction.
5) Gravel bed- similar to a sand cushion, its thickness is also about 15 cm. The crushed stone is carefully leveled over the entire area of the future foundation, leveled in height (reinforcement rods with marks placed in advance in the thickness of the sand and gravel cushion can serve as beacons), and rammed.
6) Assembly of the FSMP body consists in laying out metal structures and wood concrete blocks according to the project - it is best to start with formwork blocks (along the perimeter), laid on the end (300 mm high) and fastened together (gravel/block, block/block) using masonry mortar; all metal structures must be securely fastened together (binding and welding does not matter).
7) Arrangement of outputs of communication systems(water, sewerage, electricity) - the wood concrete filler block is easy to process (sawed, cut), so a lot of time and effort is not spent on arranging the exits.
8) Layout of masonry mesh
9) Installation of warm water heating- carried out in accordance with the project.
10) Layout of masonry mesh(200x200mm., D6) - the mesh must be laid out with a slight overlap (one cell is enough), and also tied with tying wire to the metal structures in some places (ensuring there is no movement of the mesh).
11) Filling with concrete (grade no less than M25)- the use of a concrete pump and a vibratory screed will speed up and simplify the process, as well as improve the quality of execution of the FSMP.
After the FSMP has completely dried, you can begin laying the walls of the future structure!
Wooden I-beams are a modern high-tech material that has no analogues in terms of price and quality ratio with an estimated rafter length of more than 5 meters. This roof will last long years, without deforming or collapsing under the influence of natural factors. The InterCity company calculates and selects I-beams for rafter system, we also give recommendations on installation and joint solutions for wooden I-beams own production made from high quality materials using special technology.
I-beam production technology
Wooden I-beams are made of OSB boards and planed timber chamber drying(Wood series), as well as LVL-timber glued using European technology (LVL series).
Advantages of a wooden I-beam:
- durability;
- ideal declared geometry;
- use only dry chamber-drying material;
- possibility of installing long spans ( maximum length is 12 m);
- high accuracy and stability of geometry;
- possibility of year-round use in construction;
- Possibility of internal installation engineering communications;
- convenient installation (5-10 times faster than for reinforced concrete monolith, hollow-core slab and board), with minimal labor costs and without the need for special equipment.
Floor beams (I-beams) do not crack or deform over time. GreenLum products are an excellent alternative to heavy and difficult to work with metal and reinforced concrete coverings, the installation of which is associated with the need to perform “wet” work, additional involvement of reinforcement workers, concrete workers, etc.
Applicable in:
- basement floors of houses made of gas blocks, foam blocks, gas silicate, wood concrete, aerated concrete, foam concrete;
- interfloor floors of houses made of aerated concrete blocks, foam blocks, gas silicate, wood concrete, aerated concrete, foam concrete;
- attic floors houses made of aerated concrete, foam blocks, gas silicate, wood concrete, aerated concrete, foam concrete;
Don't want to get into the details?
Send us drawings of your block house, you can even make it by hand. We will promptly draw the layout of I-beams, select the cross-section, calculate the quantity, and also guide you on the cost and time of production of the material. If necessary, we will calculate the cost of delivery. The ceiling in a house made of blocks must be no less strong and reliable than the walls, so we calculate the beams for a load of 400 kg/m2, which ensures structural rigidity according to SNiP.
