Prefabricated wooden beams for the floors in the house of aerated concrete

Hardwood floors to floors in the house of aerated concrete - the most fuel efficient, safe and fabricated type of overlap.

His device only requires compliance with the order of work, technology and fastening screws in the right places.

Features hardwood floors

monolithic concrete reinforcement, embedded along the entire perimeter of the building, is not mandatoryelement, if you want to overlap in a house with wooden beams.

This method of construction is simple, quick to perform and surprisingly very durable.

Overlapping can be made of timber, edged boards or logs, which is extremely rare.

From new types of material is worth noting laminated veneer lumber and wood I-beams, which have a high tensile strength.

Wooden floors in the house are:

1. mezhbalochnym a filler in the form of shields for bars, rolling out of boards;
2. filled with insulation, vapor and waterproofing materials;
3. with a specific binder material: plasterboard, particleboard, plywood, paneling.

Now specifically about the features hardwood floor:

• Hardwood floors increase the minimum weight, which tells the load bearing elements of the design of the house, which is very important, if the house more than 2 floors;
• Easy installation: wooden beams, you can even manually set the maximum with the help of third-party rights, in contrast to standard concrete, which is needed to move the crane;
• Sustainability: coniferous attenuate volatile, which have a positive effect on the body (which is proved by the example of a cedar barrel saunas);
• overlap length must not exceed 5 m, since the wood has less strength characteristics than steel and concrete (calculation - not more than 400 m2 kg load);
• Overlapping of wood always requires insulation from moisture and heat, as it can quickly come into disrepair;
• This is not a monolithic structure - it must be collected gradually, layer by layer, preventing hygroscopic property, what will help a variety of hydrophobic compounds;
• Pirozaschita (protection against fire) - an important characteristic of the overlap.All adjacent surfaces should be impregnated with special compounds or carefully plastered.

Types hardwood floors

Wooden type is mounted directly, without preparation, drying, so ready to take the load immediately.Connect it to the load-bearing walls with the help of the system slots.

following types of floors.

Traditional beamed

This design consists of a monolithic beams or laminated timber, which is spread over the subfloor - the transverse board, on top of a warm floor spreading and other coatings.

amount of such beams are as follows: up to 40 cm in height, to

20 cm wide, up to 15 m but in particular we have articulated the number "5" - five meters permissible maximum overlap length..Where the number 15?

The fact is that if the floor structure will be supported by 1-2 or more rows of walls beside, there is no reason to lay the beam parts when you can lay one long, center and after further strengthen spacers.

Precast concrete construction is allowed only in the case of several retaining walls.

lightweight ribbed

The species rarely found, but it is extremely important in cases where the house is built from wooden frame.

The main difference between this overlap - the ribs and planking Stela every 30-50 cm

Permissible length not exceeding 5 m and the width -. Only 30 cm high.Sheathe overlapping plywood, chipboard, rarely steel tape.

For soundproofing it is necessary to use mineral wool.The use of such overlap in the aerated concrete building is justified only design features a single room.

girder-ribbed

inner lining made from a combination of the above two types, which consists of ribs and beams.

ribs stacked across the beams, which, by the way, should be less because of load balancing features.

Wood spent less, but to install this version is slightly more complicated the previous two.

technological nuances of creating overlaps

Hardwood floors between the floors in the house of aerated concrete requires strict compliance with stacking technology, since there is a real chance to break the geometry, weight distribution, which will eventually lead to collapse.

To avoid this, you need to take into account a number of nuances:

1. beams fit into the wall during construction.Construction is carried out before the finishing work.Be sure to perform engineering calculations of the strength of a hypothetical ceiling of a material to know the number of beams, and a step of stacking the required dimensions;
2. beams coupled into the wall at the stage of its construction: the nest is done, and their depth should be half of the total wall thickness.If you do a through slot, then it is necessary to seal the insulation with a vapor;
3. first always fit the extreme beams that need to align the level of direct and long boards, laid on top of the board edge.To correct the skew is better placed under the beams cutting boards required thickness.Intermediate beams are aligned by a straight board that fits over the extreme;
4. mainstay subfloors floors above the ceiling is beam thickness greater than 5 cm, which is fastened with screws.Over it fit board subfloor, which can be subtle and not planed.Boards are placed across the beams are attached to the bars with screws.All elements of the future floor at this stage, before the direct attachment to each other, you need to handle antiseptic;
5. To create the floor slab must be mounted on top of a layer of steam and water proofing.Fit, for example, polystyrene strips overlapped, after all joints are glued shut.Over it should be insulation plate (ecowool, expanded clay, expanded polystyrene) and only after - the finish flooring.It is undesirable to use tiles, granite tiles, which weigh a lot.The best option, in terms of weight, reliability, durability - parquet or wood board.

Practical assembly instructions

Thus, the material is prepared, the tools in store, load-bearing walls stand and wait, when we prepare to build the overlap.

Step 1: Calculation of construction

Installation always selects the shortest size of the room.From section overlapping bases depends on the size of the installation steps.Usually, it is 1 meter.

guided by the rules: better to take a timber with a large cross-section, than to put a stockade of the weak bars.

For the first timber is important perfectly flat surface that will not allow the slightest inclination in the horizontal projection.

Need bars that can withstand the load is not less than 400 kg per sq.m area.

Optimal sizes supporting beam height is 1.5 to 1 width.overlapping device for aerated concrete should be done with a stock: it is better to take a longer and then cut with a hacksaw.

Step 2: Preparing for installation

When building the walls of aerated concrete is necessary to provide openings for overlapping elements.opening Step - 1 meter, depth - 30 cm width - 30 cm and more.

End of the ceiling after the installation of the beam does not poured to avoid rotting.Bearing bars in any case should not be placed close to parallel to the wall.

Step 3: slab floor

consists of several major operations:

• 1 day before installation we coat all the wood elements of the antiseptic and flame retardant composition.The ends do not touch;
• tries on beams, saw off a hacksaw so that on both sides of fixing was 45 cm from the size of the room.Cut away should be at an angle of 60 degrees, which eventually will form a trapezoidal cut-off, which will add strength only by its geometry;
• We put extreme beams, exhibiting their level tsentruem flat beam perpendicular to the direction of stacking.The ends of the beams should not rest against a wall - leave a ventilation gap of 3-5 cm;
• align all floor joists, check their level of honesty, you can assign each on-site dry gravel;
• At the end of concreting the landing nest in the walls of aerated concrete cement with gravel;
• Once the cement is dry, you need to perform thermal insulation: polystyrene, expanded clay, ecowool - will fit all;
• put on top of insulation waterproofing: liquid rubber mastic, seamless insulation polyurea polymer coating, resin injection, and so on;
• After the waterproofing on the screws are put logs - bars to deck him floorboard;
• top of the floorboard (the so-called draft floor) spreads the final floor covering;
• overlap - this floor and ceiling at the same time, because the ceiling for the device, you need to do the same procedure as for installing the floor: fasten with screws / glue insulation, after impregnating a hydrophobic composition, strengthen thin logs and only after tinkering ceiling.

as summarizing all the above, we offer watch a video on how to properly create the overlap of zero.

Conclusion

Monolithic construction allows the use of timber floors in the event that the design load on it does not exceed the margin of safety for the intended use of the overlap type.

Make slab of wood or the same aerated concrete - a purely personal choice, but the obvious advantages of wood bow their choice in favor of it is a wooden structure, which is not inferior to other types of floors.
