Wood floor deformation reasons and methods of preventing deformation

wood floor has moist insulation, sound insulation, heat preservation, the advantages of strong elastic, so home outfit, ground brick floor, majority is wooden floor, but in use, there are some disadvantages, because of the humidity and temperature, such as wood floor deformation, expansion, etc. The wood floor deformation? If you encounter such a situation, you will start from what? To suit the remedy to the case first, strive for one-time deal with first. Look for the analysis of the reason and repair method, for example, to prevent late, what are the methods of prevention, there are corresponding method, the content is as follows:

a, wood floor deformation reason

1, the material problem, the more sales market is aggrandizement wood floor, the base material of aggrandizement wood floor that are made using medium and high density board, its relative density is small, large expansion coefficient; Aggrandizement floor after the shop is good, once the water, if not in time to wipe, easy foaming, deformation caused by the water absorption expansion; The wave resistance is not strong, in the humid environment, the stability is poor, so the aggrandizement floor is not in water.

2, too much water, water is the main factor causing deformation of real wood floor, source has three parts, respectively is the moisture in the air, the keel moisture, the moisture in the ground; In the process of the pavement of the floor, can effectively prevent the water come into contact with the three parts is the key factor of floor the reverse side, be sure to prevent.

3, improper installation, the installation of wooden floor in the construction process, the expansion slot of wooden floor is not standing, laid is too tight, the easier for wood arch, which can lead to deformation. Therefore, the installation of wooden floor is also a need to pay attention to the problem.

2, wood floor deformation solution

1, the ground moisture, generally USES two felt '' three oil, asphalt felt paper two layer three layer, again in the above a layer of cement, to prevent harmful gas release; This is a kind of simple processing method, is to spread a layer of moistureproof film.

2 moistureproof, plates, after the real wood floor in the shop, sometimes tile sheet deformation, mainly by the damp ground, the ground wet, because of the ground get damp, or local water seepage causes such as; Dragon framework can be used when laying method, because of the wet bilge drying shrinkage of lumber and wood, horizontal scalability and the difference is very big, so, after dragon framework in tide, also will be out of shape, craze, springing, make the floor appears tile sheet; The bedding cushion method is adopted, which can effectively prevent the above situation happened, it leaves out the skeleton, cannot be deformation on root cause. Testing moisture permeability coefficient is small, has a good well protected against dampness moisture performance. Matting treasure well off the moisture on the surface of the concrete and wood floor, also can avoid the wood floor tile sheet.

3, install balance plate expansion, as well as the keel and add a layer of floor, some installation, MAO asked plate between 0. 2 mm wide gap, some requirements of indoor and leave gaps in the four corners, convenient floor releases moisture; Some requirements are set to use inside the wall the expansion joints of the floor spring, some aluminum alloy keel, some with orbital floor installation method, etc.

4, change new floor, repair, remove the deformation of the plate, the ground with cement blocks, change new floor, the floor will level off again.

5 wriggle through the earth, remove the block and the surrounding floor ventilation perforated, wriggle through the earth can alleviate problems; Large pry up arch of the floor, waiting for the ground, keel after drying, the floor laid back again; Keep the floor normal contact with the outside world, to that of the atmospheric humidity balance; If the arch is serious, can consider to change. To prevent the arch since the floor, the experienced teacher laid on the shop floor in advance when they set aside a small aperture, leave the floor to 'heat bilges cold shrink' space.
