The construction process of sports wood floor is delicate and rigorous, which is directly related to its final performance and service life.
Before construction, the civil engineering must be completed, the construction site must be clean and tidy, the ground must be waterproof, moisture-proof and air-proof, and the indoor water, electricity, gas and ventilation installation projects must be completed and pass the pressure test. At the same time, the moisture content of the floor material and the ground and atmospheric humidity must be accurately determined to ensure that the environmental conditions are suitable.
The first step of construction is to level and divide the ground. Using the 9-point method, the horizontal plane is determined with the help of a spirit level and marked on the side wall, and the position of the outermost dividing line is also marked. Confirm that the cross intersection is on the same horizontal plane, treat the protrusions and depressions accordingly, and then apply anti-corrosion materials on the surface of the pads.
Then install and lay the keel and small keel. First, check, mark, saw and cut the keel and small keel to ensure that the surface is smooth and the saw cut is straight, and then apply anti-corrosion materials. The «middle keel» is laid along the longitudinal center line of the site in a single continuous line, and the center line coincides with the surveying center line. After the surface elevation meets the requirements, it is connected and reinforced with wooden plywood, and then the small keel is laid and clamped and nailed vertically to the keel. When installing, pay attention to the position relationship between the small keel at the side keel end and the pad, wall and adjacent keel, and reserve a certain gap. After the installation is completed, check the flatness, use an electric planer to level the part and apply anti-corrosion material again, and then conduct the keel installation inspection.
There are also particularities in laying the subfloor. It needs to be planed, polished, and thickened on both sides, and the ends are aligned. The laying angle meets the design requirements, the end is flush with the keel and the small keel, and the joint falls on the keel, and it must not be suspended. When arranging the boards, the width and narrowness are evenly matched, the joints are staggered, and the boards are evenly spaced. They are nailed to the keel with steel nails, and the nail heads are hammered into the subfloor. After that, the upper surface of the subfloor is corrected and checked for flatness, and the installation inspection is completed.
