Indoor basketball court wooden floor foundation installation conditions

Indoor basketball court wood floorGeneral site conditions

The moisture content of the cement floor should not exceed 5%, and the site conditions must be weatherproof. All wet work must be air-dried. The relative humidity of the air should be the same as predicted when the building is used, otherwise heating and/or extraction systems will be required. Before the construction, the polyethylene film test has been passed and the requirements have been met. During the installation period and after the construction site is completed, the site temperature for installing the wooden floor of the indoor basketball court must be between 18-21°, and the air in the hall must The relative humidity should be controlled within the range of 35%-50%.

A. Concrete foundation: The detection error with a 3-meter level ruler is not greater than ±5mm, otherwise the level must be adjusted with the appropriate material.

B. Waterproof membrane: The minimum 0.15mm polyethylene waterproof membrane is fully covered, and is pasted on the wall with a 200mm lap at the lap joint.

C. Wood Flooring: Cut and lay the boards, and provide expansion joints along the perimeter and other fixed points.

D. Allowable expansion and contraction: The sports wood floor on each side reserves a shrinkage joint of 20-40mm in width to ensure the shrinkage and expansion of the wood floor under the conditions of mechanics and air dryness and humidity.
