Due to the influence of climate factors in coastal cities and high air humidity, special attention should be paid to the selection and installation of sports wooden floors. We recommend the following points:
1. Adjust the moisture content of the floor in advance according to the local climate
In coastal areas, the moisture content must be strictly controlled. The moisture content is best at 11-12%, and the maximum should not exceed 14%. Considering factors such as construction time, transportation distance, weather conditions along the way, site environment, weather, whether to store and how long to store, sports wooden floors must be well regulated before leaving the factory.
2. Take good measures to waterproof and moisture-proof the ground
① The foundation ground of the sports hall must be waterproofed in advance according to professional requirements.
② The foundation ground (usually concrete ground) is required to be as flat as possible, without sand or unevenness on the surface.
③ When leveling, the flatness error should be kept at ≤3mm (measured with a 2m ruler and a wedge-shaped feeler gauge); the height error of the entire site is ±5mm. If there is an error, professional leveling should be performed in advance with cement, quick-drying powder, etc. The leveled ground needs to be tested again and can only be installed if it meets the requirements.
④ The concrete and cement foundation ground should be dry, and the humidity should be controlled within 10%; and the ground should be kept clean and free of any debris.
3. Moisture-proof measures in floor installation
In coastal areas, due to high humidity and easy breeding of insects and ants, waterproof, moisture-proof, insect-proof, mildew-proof and other technical measures must be taken during construction, especially:
· Pay special attention to sealing the joints when installing the moisture-proof membrane;
· Leave a gap of 1-3mm between the joints of the keel and the joints of the rough board, and generally leave a gap of 0.2-0.5mm between the surface floors according to the width of the floor and the moisture content of the floor at that time and the local wood balance moisture content;
· Wood floors must be used as ventilation holes around the site to ensure the circulation of air in the hidden project and indoor air to prevent the rotting and deterioration of internal materials;
· All hidden parts are treated with moisture-proof, anti-corrosion, fire-proof, anti-termite and anti-deformation.
