Due to the large installation area of the wooden floor of the stadium, the uneven temperature and humidity of the environment will inevitably lead to the expansion and contraction of the floor itself. During the installation process, there must be a corresponding process to ensure that the floor will not change during normal changes. The concentrated stress is consistent, resulting in the deformation, cracking, and bulging of the floor.

Be sure to understand the environmental conditions of the place where the sports floor needs to be installed, such as the annual average temperature, humidity changes and the equilibrium moisture content of the wood. From these data, the moisture content of this batch of wood floors was adjusted in the project to meet the local demand without causing great changes in the floor. When installing floors on construction sites. Be sure to allow expansion joints to offset the amount of deformation caused by changes in the moisture content of the floor. Generally, the joints of the keel and the joints of the wool board should leave a gap of 1-3 mm. The surface floor should be based on the width of the floor and the land at that time and the local wood balance moisture content.
Generally, a gap of 0.2-0.5 mm is left, and the surface gap must be even and straight, giving a perfect three-dimensional feeling. When encountering hardware such as walls and columns, an expansion joint of 3-5 cm must be left, and the ventilation skirting line should be pressed on it. The wooden floor must be used as ventilation holes around the site to ensure that the air of the concealed project and the indoor air can circulate and flow, and to prevent the internal materials from rotting and deteriorating, and external ventilation holes must not be used, because if the concealed project is connected to the outside of the gymnasium, they will be separated. Due to the high frequency of external climate change, the frequency of environmental changes in concealed projects will inevitably increase. The so-called wood "wet for three years, dry for three years, and use it for half a year" clearly illustrates the wood You are afraid of frequent changes in the environment. Unless the environment is humid, forced ventilation must not be carried out. The principle is the same as above.
In order to ensure the accurate and strict installation of the floor, it should be ensured that the key parts must be installed with professional tools during the entire installation process of the sports floor. Must be an airless sprayer. Learn more about NB sports wood flooring engineering cases: http://yundongmudiban.com/products/
