    Surface phenomenon: wood floor board arched up partially, or a few pieces of wood floor arching up. Analysis: Continuous rainy weather, the relative humidity in the air is high, did not take wetting measures, moisture in the air is absorbed by the wooden floor hygroscopic expansion; wood flooring hygroscopic expansion after flooding;
    Long-term empty customs house, uninhabited, poor ventilation, paint the middle layer of water evaporation after evaporation is no place to be absorbed by the moisture absorption and expansion; the concrete moisture content is too high, moisture-proof isolation layer is not sealed and hygroscopic expansion; When the adjacent blocks are not required to reserve the stretch seam between the damp air swell after expansion arch, or even paint cracks; wood floor pavement larger or wider, did not take sub-measures. Preventive measures: Regularly open the window ventilation; and reserve the construction of the extension seam, the section seam and the adjustment of the extension seam between the adjacent plates as required.
    Solution: Do not affect the use of functions, 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 resurfacing, Seams and adjacent panels are reserved for stretching.
