Ultra-thick multi-layer thermal insulation structure of a building and its construction method

Abstract

The present invention discloses an ultra-thick, multi-layer insulation structure for buildings and its construction method. By using screws to squeeze and anchor multiple expansion segments of expansion bolts to create interlayer bonding, the multiple insulation layers of the ultra-thick, multi-layer insulation unit panels are locked to the building's exterior facade. Combined with a bottom support structure, the insulation unit panels are supported and prevented from falling, ensuring that the ultra-thick, multi-layer insulation unit panels can be securely installed on the building's exterior facade, enriching the building's unique exterior facade design. This invention solves the problem of using traditional exterior wall insulation installation structures to install multiple, ultra-thick insulation and decorative layers on the facade, which cannot meet the requirements for interlayer bonding, falling prevention, and side protection.

[0002] With the diversification of architectural design, there are frequent designs that increase the thickness and number of insulation layers to adjust the building's facade shape. For example, rock wool is used as the base insulation layer, and extruded polystyrene boards are used to supplement the facade thickness and achieve the desired shape.

[0003] When the facade insulation and decoration layers are multi-layered and super-thick, the traditional exterior wall insulation installation structure is used to install the super-thick insulation structure system, which cannot meet the requirements in terms of inter-layer tensioning, anti-falling and anti-side protection.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.
