The quality of the professional interlocking wood indoor basketball sport surface is closely related to the requirements of the cement foundation. Therefore, in order to maximize the service life of the outdoor plastic basketball court, it is necessary to ensure the quality of the cement foundation as much as possible during the construction process. When laying the cement base of outdoor plastic basketball courts, sports floors, etc., it is necessary to add steel bars in an appropriate amount to increase the integrity of the sports ground, which can prevent the cracking of the cement foundation. Specifically, the cement foundation of an outdoor plastic basketball court has the following requirements:
First, the slope requirement. The slope error of the cement floor of the outdoor plastic basketball court is limited to 3‰-5‰. If the outdoor plastic basketball court has a water removal system, such as large-scale cleaning, the slope is required to increase accordingly, and there should be a drainage floor drain or a site drain.
Second, the expansion joint. In the interlocking elastic flat PP mat sport flooring foundation construction, it is necessary to set a 15mm expansion joint in the center of the entire rectangular outdoor plastic basketball court to run through the entire course. The expansion material is removed, and a special joint filler is sealed on the seam to prevent the cement from expanding and cracking due to the difference between the hot and cold temperatures.
Third, drying requirements. According to international standards, after the completion of the ground floor of the outdoor plastic basketball court, it takes more than 28 days to ensure the dryness of the prefabricated interlocking indoor tennis court.
Fourth, embedded parts. In the basic construction process, it is necessary to reserve fixing parts for other related facilities of the outdoor plastic basketball court, and the embedded parts are provided by the contractor.
Fifth, go to the water test. The water depth of any water or "bird bath" shall not exceed one coin, and the excess shall be repaired with cement.
