Description

Technical Field

[0001] The utility model relates to the technical field of foam boards, in particular to a foam board convenient for assembly. Background Technique

[0002] The EPS board (also known as the benzene board) is the abbreviation of expandable polystyrene board. It is a polystyrene foam plastic board with a closed-cell structure, which is made by heating and pre-foaming expandable polystyrene beads and then heating and forming them in a mold. It is made from raw materials through processes such as pre-expansion, ripening, forming, drying, and cutting, and is widely used in fields such as construction, thermal insulation, packaging, refrigeration, daily necessities, and industrial casting. It can also be used for the manufacture of exhibition venues, product showcases, advertising signs, and toys. To meet the national building energy conservation requirements, it is mainly applied to external wall external thermal insulation, external wall internal thermal insulation, and floor heating of exterior walls.

[0003] When the existing foam board is under construction, glue needs to be applied to both the bottom and side walls of the foam board to improve the connection tightness between the foam board and the wall and between foam boards. However, the just-glued foam board needs to be stabilized by a clamping device to ensure that the colloid dries and sets. Otherwise, the foam board will warp, especially at the adjacent gaps, which will affect the tightness of the foam board. The traditional method is to add new fixtures for stabilization, which increases the workload of secondary construction and is not conducive to the rapid installation of the foam board. Therefore, it is urgent to solve this problem. Content of the Utility Model
