Active-passive integrated fireproof insulation board and preparation method thereof

Abstract

The invention relates to the technical field of fireproof insulation boards, and provides an active and passive integrated fireproof insulation board and a preparation method thereof.The active and passive integrated fireproof insulation board comprises insulation boards, the top sides of the insulation boards are fixedly connected with veneers, the four corners of each insulation board are each provided with a first limiting groove and a second limiting groove, and limiting discs are arranged among the multiple insulation boards; and the limiting disc can be inserted into the second limiting groove, a through hole is formed in the middle end of the limiting disc, a threaded sleeve is fixedly connected to the middle end of the bottom side of the limiting disc, threaded grooves are formed in the outer wall and the inner wall of the threaded sleeve, and a bolt is connected to the middle end of the top side of the limiting disc through the threaded grooves. Stable installation is achieved through cooperation of a limiting disc, a threaded sleeve, a bolt and a limiting rotating block. During use, the screw sleeve is fixed in a wall firstly, then the plates are positioned through the second limiting grooves, finally the bolts are tightened to enable the limiting rotating blocks to be clamped into the first limiting grooves, and through the clamping effect of the limiting rotating blocks and the limiting disc, it is ensured that the multiple plates are firmly connected, and loosening and falling are avoided.
