The floor gap is too large because the floor shrinks and swells. Analysis from the aspect of quality is caused by improper control of the product's own moisture content. In addition, the unevenness of the ground, the bad combination of the buckles, the uneven sizing, and the like also easily cause such problems. 1. Open type: Common slits generally have the following situations: There are triangular slits at the end of the floor, triangles at the ends and sides, or gaps at the sides, and irregular distribution in the room. 2. Causes: (1) Unilateral expansion caused by the ventilation of damp-proof membrane joints When the laminate flooring is installed, the joint of the moisture-proof film is not tightly adhered with waterproof tape. One side of the floor is above the damp-proof film and one side is connected with the damp-proof film. Since the joints of the moisture-proof film are not tightly adhered with the waterproof tape, the moisture intrusion causes one side of the floor to become longer, and the lengths of the two long sides of the floor are not equal, so that the end of the floor produces a triangular seam. The characteristics of this situation are: a) After the floor has been installed, there is no triangular seam, which occurs after a period of use; b) The water content on both sides of the floor strip is inconsistent, generally differing by more than 2%; c) After the floor is opened, it can be seen that the moisture-proof membrane is not stuck with waterproof tape. Such problems occupy a considerable proportion of floor triangle gap complaints. The moisture-proof film must be made of waterproof tape to ensure airtightness and avoid problems. (2) Installation quality problems Floor installation, due to uneven installation force, resulting in the floor to create a triangular gap, the direction of the arrow can be tightened to eliminate the triangular gap and the side of the gap. The characteristics of this type of problem are: After the floor is installed, there is a triangular seam; b) There is a gap on the side of the floor; After the floor is opened, the damp-proof film has been waterproofed with waterproof tape; d) After the floor is stretched, the gap between the triangle gap and the side edge can be eliminated; e) The ground is uneven, with his feet on the floor, the floor vibrating up and down, feeling very uncomfortable, accompanied by a buzzing sound. (3) Improper humidity control: When the room is unoccupied for a long period of time, if the humidity in the room is not adjusted in time, the floor contraction may cause a crack or arching.
