Partial arching of wooden floors has seriously affected the beauty and use of the living room. This is what every owner who is doing house decoration is the most unwilling to see. The main reasons leading to local arching of wooden floors are as follows: (1) The moisture content of the top floor wood floor is high or low. When it is too high, the wood floor will lose moisture in the dry air, and the cross section will shrink, and the warp will occur. When the floor is low, the wood floor will absorb the moisture of the air and cause arching. (2) The fine stone concrete or thermal insulation materials laid between the wooden joists are not dry. After the floor is laid, the drums will be deformed after absorbing moisture. (3) Ventilation holes are left in the unpatched moisture-proof layer or the floor of the floor for four weekends. The internal moisture cannot be discharged in time after the surface layer board is laid. (4) At the end of the fur floor, the gap or the gap is too small. After the moisture expands, the surface layer board is drummed and deformed. To prevent the water floor surface from druming, deformation, wood flooring construction should be strictly to do the following: (1) control the moisture content of wood floors, the moisture content should not exceed 12%. (2) The fine stone concrete or thermal insulation material that is poured between the wooden joists must be dried before laying the floor. (3) Reasonably set vent holes. Wooden trellis should be connected to the hole and trough, and connected to the floor surface ventilation hole, no less than two air holes in the floor surface layer, not less than two on each side of the skirting board ventilation hole, the ventilation hole should be kept open, in order to facilitate Air circulation. (4) wooden floor under the board (that is, wool floor), board seams should be properly opened, usually 2 ~ 5mm, the surface should be planed, adjacent panels should be staggered, around the wall from about 10 ~ 15mm. (5) 1Omm gap should be left between the surface layer of the wood and the wall, and be covered with skirting board or kickboard.
