Fabricated building external wall heat preservation device

Abstract

The invention provides a fabricated building external wall heat preservation device, and belongs to the technical field of building external wall heat preservation. The fabricated building external wall heat preservation device comprises a wall body, a second heat preservation wall plate and a first heat preservation wall plate, wherein the second heat preservation wall plate and the first heat preservation wall plate are connected to the side wall of the wall body through first bolts and distributed up and down; a first sealing assembly is movably mounted on the side, facing the second heat preservation wall plate, of the first heat preservation wall plate, and a second sealing assembly is movably mounted on the side, facing the first heat preservation wall plate, of the second heat preservation wall plate; and the first sealing assembly comprises a first concave cavity formed in the side wall of the first heat preservation wall plate and a first supporting plate connected into the first concave cavity through a first elastic body, and one end of the first supporting plate extends to the exterior of the first heat preservation wall plate and is fixedly provided with a first sealing layer. The fabricated building external wall heat preservation device has the advantages of convenient mounting and good heat preservation effect, compared with the prior art, a gap between the adjacent heat preservation wall plates can be reduced to a great extent, and thus the situation that heat in a building body is lost from the position between the two adjacent sets of heat preservation wall plates is avoided.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation of building exterior walls, in particular to a prefabricated thermal insulation device for building exterior walls. Background technique [0002] At present, buildings are striving towards the goals of factoryization, prefabrication, and integration. Prefabricated and modular buildings are the product of the development of scientific and technological achievements. It uses the factory assembly line to manufacture all the components required for a house in the factory. Then it is transported to the construction site, and it is a type of building that is hoisted and spliced ​​on site. As prefabricated buildings are gradually being used more and more, the traditional wall insulation system has encountered a bottleneck when it is applied to prefabricated houses. [0003] In the prior art, when the thermal insulation wall panels are assembled on the outside of the wall, there will inevitabl...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the thermal insulation wall panels are assembled on the outside of the wall, there will inevitably be a certain gap between the two sets of thermal insulation wall panels. Due to the existence of these gaps, the heat inside the building is easily lost, making the building The insulation effect is poor
