Assembled sandwich heat preservation concrete shear wall structure non-dismantling formwork system

Abstract

The invention provides an assembly-type sandwich thermal insulation concrete shear wall structure free formwork system. Including wallboards and corners, the composition of the wallboards and corners includes steel silos, outer wall panels, inner protective plates and bolts, and the steel silos are cavity-filled structures composed of several cold-formed C-shaped steel welds. The steel silo, the outer wall panel is composed of a rigid non-combustible material facing layer, a protective layer and an insulation layer, the insulation layer and the protective layer are fixed on the outside of the steel silo by bolts, the decorative layer is fixed outside the protective layer, and the inner protective plate Installed on the inner side of the steel silo, the web of the cold-formed C-shaped steel has through holes. The present invention completes most of the building wall construction procedures such as wallboards, outside corners and outside corners by factory, and only needs to pour concrete in the cavity to form a load-bearing layer on site to form an energy-saving and heat-preserving wall. Not only can the construction progress of the building be accelerated and the construction period shortened, but also it is beneficial to improve the quality of the wall and reduce the cost.

Description

technical field [0001] The invention relates to a building material, in particular to a building wall component. Background technique [0002] EPS insulation modules have been widely used as insulation materials for building walls. At present, the methods of building the wall insulation layer with EPS insulation modules are as follows: (1) First construct the load-bearing layer of the wall, then paste the EPS insulation module on the load-bearing layer to form the insulation layer, and then lay a protective layer outside the insulation layer of the EPS insulation module; ( 2) The insulation layer is formed by connecting the EPS insulation modules, and a formwork is set on one side of the insulation layer to form a cavity, and then concrete is poured in the cavity to form an integral body of the EPS insulation module and the concrete, and finally outside the insulation layer of the EPS insulation module Lay out the protective layer; (3) Connect the EPS insulation module to f...

Problems solved by technology

The disadvantages of these methods are: the splicing of EPS insulation modules, the installation of templates, the pouring of concrete, and even the construction of protective layers must be carried out at the construction site. long
