Description

Technical Field

[0001] This utility model relates to the field of plywood technology, specifically to a high-temperature resistant flame-retardant plywood. Background Technology

[0002] Plywood is a sheet material made of three or more layers glued together with adhesives. It usually uses an odd number of veneers, with the fiber directions of adjacent veneers glued perpendicular to each other.

[0003] A search revealed a Chinese patent with publication number CN215882863U that discloses a high-temperature resistant flame-retardant plywood. The key technical point is that it solves the problem that existing plywood is basically made of several layers of pure wood boards glued together. When used, it cannot effectively isolate the fire source or open flame when exposed to external high temperatures or open flames, which leads to damage to the plywood. At the same time, the glue is also easy to dissolve or burn in high-temperature environments, which may lead to unstable bonding between plywood boards and shorten the service life of the plywood.

[0004] However, it has been found in the above-mentioned solutions and existing technologies that simple snap-fit ​​installation is usually used. After the plywood is installed, it is easy for it to slip off, resulting in low safety. In addition, the existing plywood has poor high temperature resistance.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

A limit groove is formed on the upper surface of each connector 2, and a limit block is slidably connected to the inner wall of each limit groove. The outer surface of each limit block is fixedly connected to the outer surface of the corresponding sliding block.

[0008] Furthermore, the outer surface of each sliding block is slidably connected to the inner wall of the corresponding cavity, and a guide rod is slidably connected to the inner wall of each sliding block.

[0009] Further, the outer surface of each guide rod is in sliding connection with the inner wall of the corresponding limiting rod, and the end of each guide rod away from each other is in fixed connection with the inner wall of the corresponding cavity.

[0010] Further, the inner wall of each mounting frame is fixedly connected with a base plate, the upper surface and bottom surface of each base plate are fixedly connected with a heat insulation plate, and the side away from each other of each heat insulation plate is fixedly connected with a high-temperature-resistant rubber plate.
