(54) METHOD FOR INSTALLING WOOD FLOOR PLATES

one

The invention relates to the construction, in particular to the construction of buildings with the use of wood-based panels for the coating and the lining of floors.

There is a method of laying wood floor slabs, which provides for acclimatization treatment of pl in a room with a relative humidity of not more than 60% and the subsequent adhesive attachment of plates to the base of the floor with uniform pressure over the entire area of the floor covering 1

The disadvantage of this method is that it is difficult to provide up to 60% of humidity when laying the plates, as well as the unreliability of maintaining the flatness and strength of the floor.

At the stage of laying and operation, the humidity of the air may increase to 80% and higher; In addition, as the paint layer dries, the coating plates will become more and more wetted during wet cleaning. Under these conditions, inevitable increase in the size of the plates and the Formation of spacer forces, causing their detachment and curvature.

The closest technical solution to the invention is the method

the laying of wood-based panels, which includes changing the moisture content of the plates and attaching them to the base of the floor with fasteners while reducing the relative humidity of the air to 60%. Initially, an acclimatization treatment is performed, consisting in increasing or decreasing the moisture of the plates to an equilibrium sorption rate (equal to 8%), then moistening the plates to a value not exceeding 12%, attaching the plates to the base of the floor is performed with a uniform clamp 2.

The disadvantage of this method is that the real relative humidity of the air inside the building, the state building is very high and its -. Lowering when laying the plates from 75-85% to 60% is very expensive, time consuming and laborious, and the known modes of changing the humidity of the plates do not satisfy the operational requirements for the floors. When the size of attached plates is reduced, including when they shrink from the inevitable periodic moisture changes, there is a significant increase in the gaps between adjacent plates, as a result of which the putty compound drops out of ishols shortly after minor finishing. To a limited extent, the presence of plate stretching forces is a favorable factor that ensures their evenness. But it is considered that along the large sides of the plates, these forces are so many times greater than the forces acting across

adress, what time

slabs exceeds their width. Excessive stresses deform the connection, vpluyut to their violation, and violation of the conditioner eliminates the tension and evenness of the floor.

It comes prematurely to recycle floors — cut-tile into separate elements, add them6 by using nails and adhesive mastic with partial replacement of plates, then the whole floor needs to be repainted. Under conditions after occupying the house, such repairs are extremely complicated. Even if there are no other defects besides elevated seams up to 2–3 mm, butt joints, then the floor is also durable: moisture penetration into the edges of the wood boards causes their separation and accelerated wear.

The purpose of the invention is to ensure durability, increase the performance of the floor, reduce the cost and simplify the production of work.

This goal is achieved by the fact that the method of laying wood boards, which includes changing the moisture of the plates and attaching them to the base of the floor with fasteners, will reduce the plates to 20-24% and maintain until the humidity decreases by 10-14% and density by 5-6%, a short stitch or add an extra 11Ne: | ShGeshnye elements, and the humidity is not reduced.

The method involves eliminating the process of drying the air in noNre of the laying of the plates, as well as drying the plates to a low equilibrium moisture. At the same time, the moisture content of the plates is not limited to 12%, but, on the contrary, they are moistened to 20–24% (for example, in a vattel).

uvlShnoyYYaYaag penetrates the entire thickness of the plates, spreading over it evenly. Internal decreases

Tray7 bonding forces between wood particles in the wetting period weaken and the particles (fibers) change their orientation so that the density of the plates decreases by 5-6%. This process causes

 The modulus of elasticity of plates and

- When they shrink, TgiSiSamy prevents 1 W overvoltage in glue-and-on attachment.

Equally important is the factor reducing the tendency to curb Tgnium glitis with the indicated altered properties. The floor covering of the hedgehog flooring in the stage of operational moisture changes will also be comparative, less straining the connection with the base of the floor, and in the direction out of its plane. This will ensure that the edges of the plates will not be visible if the difference in. shrinkage of the upper and lower fibers in their thickness, as well as prevented bulging of the middle zone.

In this method, the fiberboard is moistened twice more intensively in the stack, and the process of holding the plates is introduced, the pattern being eliminated by optimally reducing the moisture of the plates by 10-14%, after which the plates are attached to the base. .

The nailing of the nail is changed: instead of the face, uniform in area and perimeter of the plates, it is uneven, nails are set (wooden pins, a screw, etc.) more; part along the short face sides of the plates.

This will also reduce the stress in the soy: the given floor elements and, accordingly, improve the state of the butt joints of the slabs in the critical areas of the floor.

In addition to the most common form of stitching in the form of a rectangle with the dimensions of the sides according to GOST 4598-74, the option is possible - a square plate. In these rare cases, reinforced fastening is discharged at the sides distant from the ste | n (partitions) or located perpendicular to it. Thus, a relatively large expansion of the gaps between the plates will take place outside the central floor area of the room, i.e. where butt joints are hidden by furniture.

This method allows to obtain savings in labor and material costs due to the exclusion of costs for drying the indoor air, for repairing the coating of the center because of swelling (delaminations) of the plates, as well as the cost of re-finishing.

If this method is applied not to the slabs of the floor, but to the slabs of the subfloor layer of the floor, then the positive effect will be as follows. A thin-layered Linoleum or similar floor covering will wear less because of the small gap between the underlying wood boards, and ai also close their edges to the bottom of the floor. In addition, the reliability and high performance of the floor will be ensured by the evenness of the central areas of the slabs 7 cutting, and the additional attachment of which during the wiping of the plates could not be carried out without removing the cover and its subsequent costly replacement.
