Sports wood floor installation process:
1, moisture layer: PE geotechnical moisture-proof film.
2, bearing layer: bearing layer can be used single or double keel practice, usually need to use preservatives for anti-corrosion treatment. The keel spacing is generally 400mm. According to whether the keel and the ground to do fixed and what kind of fixed, can be divided into suspended sports wooden floor system, fixed system and fixed suspended system.
3, elastic cushion layer: elastic cushion material has PU, recycled rubber, rubber, PVC and so on different kinds, mainly for the system to provide shock-absorbing performance.
4, stabilizing layer: usually use a larger width of the board, mainly plywood, OSB boards, etc., the size of the basic 1.22 * 2.44 meters, the thickness of most of the more than 12 mm.
5, panel: panel can be used solid wood composite or solid wood panels. Tree species selection of high-quality hardwood, more commonly used are hard maple, quercus, ash, beech and so on. Because maple is a long-fiber species, good toughness, moderate hardness, viewing effect is also the best, so the vast majority of the world's stadium panels are used maple. The moisture content of the panel should be lower than the local equilibrium moisture content. Foreign imports of MFMA's maple panel specifications generally have a width of 57 millimeters, 38 millimeters, 26 millimeters, 20 millimeters thick. Most of the domestic panel sizes are 22 millimeters thick with grooves and flanges.
6, paint: paint is divided into factory painted UV paint and construction site painted polyurethane paint two kinds, are required to meet the coefficient of friction 0.4-0.7 requirements. In terms of environmental protection need to be done to achieve no benzene, toluene, xylene and curing agent, paint, thinner do not contain benzene, and anti-slip, abrasion resistance, light refractive index and other aspects of good performance.
7, nails: panel nails using 50 mm T-type or L-type wood flooring special power nails; stabilization layer is usually keel joint U-type nails.
8, skirting: 80 mm × 60 mm type solid wood skirting.
9, scribing: using the same panel paint matching scribing paint.
Sports wood flooring installation precautions:
1, assembled too loose or too tight: wood floor expansion, contraction is with the environmental humidity, temperature changes. Therefore, should be based on the use of the place of environmental humidity, temperature to reasonably arrange the wooden floor assembly tightness. If too tight, the floor will arch when the expansion, too loose, the floor contraction will appear larger gaps.
2, the keel to do moisture-proof treatment: now the construction of the general use of pine lumber saw planing and into the non-dry keel, about 30 days in advance fixed to the ground, the keel and the ground is not paved between the moisture-proof layer. Laying the floor, do not check the moisture content of the keel is laid directly, then the moisture content of the keel is generally about 25%, and qualified wood flooring moisture content is generally about 12%, the humidity difference is too large to accelerate the speed of moisture absorption of wood flooring, resulting in the floor arching, lacquer cracking.
3, decoration works cross construction: construction is usually first paved wooden floor, and then engaged in other construction projects on the floor surface. In this way, after the floor is paved, it takes a month or more to polish the paint. During this period, if the floor and the surrounding environment of chemicals, moisture is not isolated, is likely to lead to wood flooring due to rapid changes in moisture content and deformation, cracking.
4, keel fixed with nails: construction with a wooden wedge plus nail fixing, wooden wedge and nail contact surface is too small, so that the grip is not enough, it is very easy to cause the wooden keel loosening, when you step on the floor there will be a ringing sound.
