Assembled polyurethane roof panel capable of reflecting light and convenient to install and fix

Abstract

The invention discloses an assembled polyurethane roof panel capable of reflecting light and convenient to install and fix, and belongs to the technical field of polyurethane roof panels. The roof panel comprises a first combined roof panel, a second combined roof panel, a protective panel, a built-in airbag, sealed airbag cushions, a combination mechanism and a positioning mechanism, wherein an internal installation groove is formed in the first combined roof panel. According to the roof panel, through the arrangement that a sealing sleeve is arranged on the outer part of the second combinedroof panel, the air-filled built-in airbag is installed in the first combined roof panel, and the sealed airbag cushions are arranged on the upper and lower inner walls of the first combined roof panel, each time two roof panels are combined, the second combined roof panel squeezes the built-in airbag through a squeezing block, gas in the built-in airbag is effectively pressed into the sealed airbag cushions, when aging and shrinking of the sealing sleeve occur, the expanded sealed airbag cushions can fill gaps in real time, the overall sealing performance of the combined roof panels is greatly improved, and the sealing performance can be continuously maintained.

Description

technical field [0001] The invention belongs to the technical field of polyurethane roof panels, in particular to an assembled polyurethane roof panel that can reflect light and is easy to install and fix. Background technique [0002] Polyurethane is a polymer compound, generally speaking, it mainly has a thermoplastic linear structure. Polyurethane materials have better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, and have smaller compression deformation properties. , and its heat insulation, sound insulation, shock resistance and anti-virus performance are also excellent. Due to the excellent performance of polyurethane materials, polyurethane materials are used in many fields, and the application range is extremely wide. Many modern temporary housing houses generally use polyurethane roof panels as the main frame of the house. [0003] Nowadays, some polyurethane roof panels are generally designed as a combination due to ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that some polyurethane roof panels need to be assembled, they are generally designed as a combined type. The combined roof panels can effectively improve the use effect of polyurethane roof panels, and can be assembled at will to improve the roof panel. area, but there is no additional sealing structure at the joint of the combined roof panels, only through the connection, the combination of the two roof panels forms a simple sealing effect, but its sealing is very poor, and the external water damage It is often easy to enter the roof panel, which will cause moisture and damage to the roof panel, and the service life will be reduced. The sealant strip has its service life. After a period of use, the sealant strip is easily aged due to the influence of the external environment, and the sealing performance cannot be guaranteed. At the same time, the general polyurethane roof panel is not equipped with adjustable reflectors on the outside. As a result, in the daytime, since the house boards are mostly white, they are not conspicuous in themselves. If the drivers of some vehicles driving around the road are distracted while driving, it is easy to fail to reach the simple houses in time, resulting in traffic accidents and failure to get out of the car. As a warning function, the safety cannot be guaranteed, and a kind of assembled polyurethane roof panel that can reflect light and be easy to install and fix is ​​proposed
