Abstract

The invention relates to a novel assembly type heat preservation externally-hung wallboard, and belongs to the technical field of assembly type heat preservation and energy conservation. In order to solve the problems that an existing heat preservation externally-hung wallboard and connecting joints are damaged rarely in an earthquake, and the aims of mechanics, thermoengineering, seismic resistance, durability, easy assembly and the like cannot be considered at the same time, the invention discloses the novel assembly type heat preservation externally-hung wallboard. The wallboard is composed of a structural frame, a heat preservation layer and an inner board, wherein the structural frame is connected with a bracket of a main structure and is fixed through a plug pin, the structural frame can freely rotate along with interlayer relative displacement, the heat preservation layer is fixed and restrained by the structural frame, and the structural frame with the heat preservation layer and an inner board are independently transported, hoisted and assembled. According to the novel assembly type heat preservation externally-hung wallboard, the advantages of materials, prestress and a combined structure are fully utilized, and the manufactured heat preservation externally-hung wallboard has the characteristics of no damage in rare earthquakes, light weight, good toughness, no cold and hot bridges, heat preservation of buildings, long service life, no cracking during transportation and assembly, easiness in adjustment, high assembly fault tolerance rate and the like and has obvious economic benefits and wide engineering applicability.

Description

technical field [0001] The invention belongs to the technical field of prefabricated thermal insulation and energy saving, and in particular relates to a novel prefabricated thermal insulation external wallboard. Background technique [0002] Under the guidance of the goal of "carbon peak, carbon neutrality", various types of prefabricated thermal insulation external wall panels have been rapidly developed and widely used in various buildings such as houses and factories. However, my country still consumes a large amount of energy every year To meet the heating and cooling needs, the existing prefabricated thermal insulation wall panels will still damage the wall panels and connection nodes under rare earthquakes, and cannot take into account the goals of mechanics, thermal engineering, earthquake resistance, durability, and ease of assembly. Therefore, it is necessary to innovate and upgrade the prefabricated thermal insulation wall panels. [0003] The "Technical Standards...
