Firewall heat insulation structure with double-layer sound insulation effect

Abstract

The invention relates to a firewall heat insulation structure with the double-layer sound insulation function. An arc-shaped female steel plate and an arc-shaped male steel plate are connected in a clamped mode through connecting and clamping assemblies. The two adjacent firewall heat insulation structures can be clamped and located through the two adjacent connecting and clamping assemblies. A separation cavity of an oval structure is arranged between the arc-shaped female steel plate and the arc-shaped male steel plate. A wall can be located and installed well. The installation efficiency ishigh. The sound insulation capability can be effectively improved through the separation cavity. Through buckling of the arc-shaped female steel plate and the arc-shaped male steel plate, the supporting force of the wall can be effectively improved, the bearing capacity of the two sides of the wall can be both improved, and the supporting strength and stiffness of the wall are ensured. Each connecting and clamping assembly comprises a locating and connecting clamping head I and a locating and connecting clamping head II and can realize double-layer connection of a base plate main body and a base plate auxiliary plate conveniently. Moreover, the adjacent walls can also be clamped and located through the connecting and clamping assemblies. The firewall heat insulation structure is convenient to assemble.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fire wall insulation structure with double-layer sound insulation. Background technique [0002] With the continuous development of prefabricated buildings, there are more and more applications of prefabricated buildings. However, the current prefabricated buildings have a major disadvantage of poor sound insulation, which limits their application. At the same time, the current prefabricated buildings Only relying on bolts for connection, this connection method affects its application performance due to problems such as the force bearing capacity of the bolts. At the same time, its thermal insulation capacity, fire protection capacity, and anti-noise ability are also greatly restricted, which limits its further development. with application. [0003] Therefore, the present invention provides a fire wall insulation structure with double-layer sound insulation to solv...
