1, walk around the floor with sound
the reason:
(1) Insufficient keel leads to uneven flooring or floor keel expansion after absorption;
(2) The floor is too thin to have a rough floor;
(3) The spacing of the keel is too large and the floor support is not strong;
(4) In the wet season, the floor is too dry.
Suggest:
(1) The moisture content of the general floor after fumigation will not exceed the standard, and the supporting keel must be selected as a regular product;
(2) Laying of the keel is recommended to lay 4 meters of keel under each flat floor, making the support solid;
(3) Requirements for laying of wooden keel and wool floor: It shall meet the standards of China Engineering Construction Standardization Association: CECS 191:2005 "Technical Specifications for Wood Flooring Paving Works".
