In the indoor basketball hall, it is necessary to use the basketball floor instead of the general household floor, and the basketball floor has very high requirements on the construction and installation process, which is definitely not something that can be handled by the installation method of our common household wooden floor. On the other hand, as colleges and universities that cultivate people and cultivate morality, the floor of the indoor basketball hall becomes more and more important, so how should the floor of the indoor basketball hall be installed and constructed?
Outsiders are often ignorant, thinking that the installation and construction of the basketball hall floor is a rough job, and a healthy person will do it. In fact, there is a set of details and techniques here. For example, how to ensure that the load function, sports suitability and other parameters of the basketball hall floor meet European standards; how to make athletes feel comfortable when exercising; how to make the surface friction coefficient of the floor meet the requirements formulated by the government, etc., are all in the installation. need to be considered during the construction phase.
Let's first make a summary of the preconditions for the installation and construction of the basketball hall floor.
Conditions General construction installation venues
Especially for the kind of poor sealing, or semi-open venues. Because the basketball hall floor is made of solid wood, and its moisture content cannot exceed 5%, it is necessary to have wind and rain protection facilities on the installation site. If it is impossible to prevent it, it is necessary to equip air-drying or drying equipment to assist in the completion of the installation.
It should also be noted that the humidity index in the venue should be consistent with the humidity used in the venue determined in advance, otherwise heating or dehumidification should be added, and the difference between the minimum and maximum humidity should not exceed 30%.
Construction conditions of sports floor
Condition 1: Concrete floor, below the straight edge of 1.5mm, needs to adhere to ≯2mm, otherwise it is necessary to adjust the appropriate material level.
Condition 2: Moisture-proof and dust-proof film, the minimum 0.15mm environmentally friendly PVC material is fixed on the wall, and a 200mm lap joint is preserved at the joint.
Condition 3: For solid wood floors, the solid wood panels are cut and panels are installed, providing elastic seams along the perimeter, at the nets and other fixing points.
Condition 4: Allow elasticity, the reserved width of each side of the floor is 20mm shrinkage joint, which can ensure the shrinkage and expansion of the gym wooden floor under the conditions of physics and dry or humid air.
The formal process of the installation and construction of the basketball floor
NO.1: keel elastic line positioning
a. Every 400mm vertical and horizontal elastic line, the ink line is required to be clear and straight.
b. The keel line and the wood grain of the floor surface are straight, the keel distance is 400mm, and the error is controlled within 5mm.
NO.2, laying elastic pads and leveling.
a. On the cross point of the elastic line, place the elastic shock-absorbing pad.
b. Calculate the elevation of the keel surface from the ground, use the infrared leveling instrument to determine the standard height of the keel, and use the infrared leveling instrument to level the elastic pads one by one, requiring the use of wooden pads with a thickness of 1-30mm.
NO.3, laying keel
NO.4. Device carrier board
a. Place the bearing plate on the keel, and the edge of the bearing plate is required to be overlapped at the center of the keel, and the bearing plate is required to be horizontal and vertical.
b. The gap between the adjacent bearing plates is controlled at 5-20mm, the distance between the sides of the bearing plates is 15-20mm from the wall, and the gap between the adjacent two rows of bearing plates is staggered by more than 400mm.
c. Use F40 air nails to fix the bearing plate and the keel.
d. During the construction of the bearing plate, pay attention that there is no debris left between the bearing plate and the keel, and check the flatness before fixing it with gun nails.
NO.5. Laying isolation layer The isolation layer is laid all over the field, and the overlap between each strip is not less than 50mm.
NO.6, panel laying.
a. The wooden floor installation generally starts from the center of the place, and a line is stretched longitudinally in the center of the place, and the double tongue floor is fixed on the bearing board according to the longitudinal line.
b. The surface floor can be laid together on both sides, and the staggered seam between every two adjacent rows of panels is more than 200mm.
c. The floor nails are 45-50 special L-shaped nails, each within a distance of 450mm.
d. Under environmental conditions, leave a 0.5-1mm elastic seam for every 4-8 panels.
e. It is necessary to press down the panel with the body weight of the panel during the panel nailing operation to prevent a gap between the panel and the carrier plate.
NO.7. Pre-embedded parts are closed.
According to the site conditions, the reserved mouth should be closed, and the gap should be uniform and beautiful.
NO.8. Leave a 10-15mm elastic seam between the panel and the wall.
NO.9 (the final step), organize the place, self-check.
a. Clean up the site after completion, and use decontamination potion to clean some polluted areas.
b. Self-check on-site flatness.
Finally, remind consumers and friends to shop around to buy the sports floor with the most cost-effective and both sides.
