The installation precision standard of indoor basketball court wooden flooring is far higher than that of all ordinary civilian wooden floors, and every detail has very strict digital constraints. The flatness of the entire court is the most basic precision requirement. Within any 2-meter measurement range, the height difference of the floor surface cannot exceed 2 millimeters. This almost harsh precision requirement ensures that there will be no slight steps on the entire court, and the athlete’s shoes will not trip due to local height differences during high-speed movement.
The levelness of the keel installation is the foundation to ensure the overall flatness. Every keel must be fixed on the ground after multiple level tests. The height of each fixed point under the keel must be adjusted with a professional shim, and no error is allowed. After the keel is installed, the construction personnel will use a 3-meter-long professional guiding rule to check every position on the keel one by one, and mark and adjust any slight height difference immediately.
The gap between the surface boards also has precise digital standards. According to the local average annual humidity data, the reserved gap between each board is accurately calculated. The width of the gap must be uniform, and the error of the gap width between different boards cannot exceed 0.1 millimeter. This uniform gap not only ensures that the boards will not arch due to thermal expansion in high humidity seasons, but also will not affect the flatness and aesthetics of the entire court due to uneven gaps.
Even the fastening torque of the fixing screws has clear standard requirements. The depth of the screws screwed into the board must be strictly controlled, neither too deep to damage the surface of the board, nor too shallow to lead to insufficient fixing force. Every screw must be checked one by one after installation, to ensure that there is no loose or protruding screw. It is these strict to almost harsh precision standards that make the finally laid indoor basketball court wooden flooring achieve the perfect state of stable structure, consistent foot feel and flat as a mirror.
