Fabricated building wall surface sound insulation composite decorative plate

Abstract

The invention relates to the field of wall surface decoration, and particularly relates to a fabricated building wall surface sound insulation composite decorative plate. The fabricated building wall surface sound insulation composite decorative plate comprises a plate body, wherein a cavity is formed in the plate body, and a sound insulation plate is fixedly arranged in the plate body; a first doorway and a second doorway are formed in the two side faces of the plate body correspondingly, a first door body is hinged to the first doorway, and a second door body is hinged to the second doorway; a driving plate is transversely and slidably connected to the end of the plate body, a fixing plate is fixedly connected into the cavity, a compressed spring is connected between the fixing plate and the driving plate, a piston cylinder is fixedly arranged in the cavity, a piston is slidably connected into the piston cylinder, and a piston rod is connected between the piston and the driving plate; and air bags located in the cavity are arranged at the first doorway and the second doorway correspondingly, and the air bags communicate with the piston cylinder; and a plug pin is fixedly arranged on the driving plate, inserting holes are formed in the first door body and the second door body correspondingly, and the plug pin is inserted into the inserting holes. According to the scheme, damage to people on the ground when the decorative plate falls off from the wall surface is reduced.

Description

technical field [0001] The invention relates to the field of wall surface decoration, in particular to an assembled building wall sound-insulating composite decorative panel. Background technique [0002] With the continuous deepening of China's urbanization process, the new army of the construction industry - new prefabricated buildings (such as prefabricated commercial housing container houses, movable board houses, prefabricated houses, wooden villas and resort houses, etc.) will become my country's next 30 According to the transformation direction of the real estate industry in 2019, the original reinforced concrete buildings will be replaced by prefabricated buildings at least 30%, so the demand for wall decorative panels in the construction market is also very large. [0003] Since the decorative board is installed on the wall, after a long time, the connection between the decorative board and the wall will become weak due to aging and corrosion, so that when encounteri...

AI Technical Summary

Problems solved by technology

[0003] Since the decorative board is installed on the wall, after a long time, the connection between the decorative board and the wall will become weak due to aging and corrosion, so that when encountering natural disasters such as strong winds or earthquakes, the wall The decorative panels are easy to fall off from the wall, and the falling decorative panels fall on the ground and are easy to hit people on the ground, which is very dangerous
