Description

Technical Field

[0001] The utility model relates to the technical field of composite thermal insulation boards, in particular to a fireproof polyurethane composite thermal insulation board. Background Art

[0002] Insulation board is simply a board used for insulation of buildings. It is made of polystyrene resin as raw material, combined with other raw materials and polymers. It is heated and mixed while injecting catalysts, and then extruded and pressed into shape to produce a hard foam plastic board. It has moisture-proof and waterproof properties, and can reduce the thickness of the building's external protective structure, thereby increasing the indoor usable area.

[0003] Currently, the insulation boards are directly connected to each other, which makes the connection relatively fragile. In addition, there is no frame on the outside of the insulation board to support the insulation board as a whole, resulting in insufficient support force provided by the insulation board after being impacted and causing it to break. Therefore, we urgently need a fire-resistant polyurethane composite insulation board to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a fireproof polyurethane composite thermal insulation board, which solves the problems raised in the background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a fireproof polyurethane composite insulation board, comprising a frame, wherein limiting grooves are respectively provided on the inner walls of the four sides of the frame, an insulation board is arranged in the frame, a placement cavity is provided in the insulation board, and a skeleton is fixedly connected to the placement cavity, rectangular blocks are respectively fixedly connected to the four sides of the insulation board, one end of a spring rod is embedded in the rectangular block, and the other end of the spring rod is fixedly connected to a limiting plug-in plate, the limiting plug-in plate is plugged into the corresponding limiting groove, the side of the insulation board contacts the inner wall of the frame, the four sides of the frame are respectively fixedly connected to connecting blocks, and the outer sides of the four connecting blocks are each provided with a connecting frame;

[0006] A plug-in through hole is provided on one side of the connecting frame and the corresponding connecting block, and limiting screws are inserted through the placement holes on the front and rear sides of the connecting frame. One end of a support spring is fixedly connected to the inner walls of the front and rear sides of the plug-in through hole and corresponds to the placement hole position, and the other end of the support spring is fixedly connected with the limiting screw. A rectangular groove is provided on the front and rear sides of the connecting block, and a sliding groove is provided in the rectangular groove and corresponds to the position of the limit screw. A limiting hole is also provided on the connecting block and located in the rectangular groove, and the limit screw is plugged into the limiting hole.

[0007] Preferably, the side of the connecting block away from the frame is designed in a vertical diamond shape.

[0008] Through the above technical solution, when the connecting block needs to be inserted into the plug-in hole, the vertical diamond shape on the connecting block can move the limit screw supported by the support spring in the plug-in hole to the rear side, so that the connecting block can be vertically inserted into the plug-in hole. When the connecting block is pushed into the plug-in hole horizontally, since the diamond design part is higher than the rectangular groove part on the connecting block, the support spring will release the limit screw for a certain distance, and the limit screw is inserted into the sliding groove. The connecting block is pushed so that the limit screw is fully inserted into the limit hole and supported by the support spring, thereby completing the frame and the connecting frame.

[0009] Preferably, a magnetic block 1 is fixedly connected to the inner wall of the plug-in through hole.

[0010] Preferably, a second magnetic block is fixedly connected to one side of the connecting frame corresponding to the plug-in through hole.

[0011] Preferably, the first magnetic block is magnetically attracted to the second magnetic block.

[0012] Preferably, bonding sheets are fixedly connected to the four sides of the insulation board, and the bonding sheets are in contact with the inner wall of the frame.

[0013] Through the above technical solution, the bonding sheet of the present application has a certain elasticity.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] This fireproof polyurethane composite insulation board improves the impact resistance of the insulation board itself by adding a skeleton inside the insulation board and adding a frame to the outside of the insulation board. It also solves the problem of fragile connections caused by direct connection between insulation boards. The design of the connecting frame improves the installation efficiency and stability of the insulation board. BRIEF DESCRIPTION OF THE DRAWINGS
