4, the room closed for a long time, no moist air replenishment, indoor air dry;
5, paving the gap between adjacent plates when the wet weather is too large, in case of dry weather, there is more dry shrinkage from the seam.
Preventive measures: Select the better stability of the wood floor materials and moisture content control in the local equilibrium moisture content requirements; wood flooring adjacent sections of stitching calculation and grasping the climatic conditions during construction, with or without leaving the appropriate extension seam; Anti-sun exposure, not long-term closure of windows and doors is not ventilated, or localized focus on hair.
Solution: Do not affect the use of function, can be a long time, such as the moisture content of wood flooring and air relative humidity after the balance, depending on the circumstances to take demolition, re-program; Or all open rebuilt, set up as required Adjacent plate stretch seam.
