Technical Field

The invention relates to a disassembly-free prefabricated hollow wall body, in particular to a disassembly-free prefabricated hollow wall body with an integrated decorative structure, and belongs to the technical field of external wall heat preservation processing production.

Background

The traditional external wall insulation is a 'rear anchoring and pasting method', namely: the method is commonly called as a thin plastering and pasting method, and not only has poor heat preservation and energy saving effects, but also has difficult quality control and is easy to cause engineering accidents such as falling off.

The integrated concept of the decorative structure is as follows: the building outer wall comprises the following components in layers from outside to inside: outer decorative layer, fire-proof and heat-insulating layer, structural layer and inner decorative layer. And combining the outer decorative layer and the fireproof heat-insulating layer through the anchoring piece and pouring the outer decorative layer and the structural layer together to obtain the decorative structure integration. The method has the advantages that the heat-insulating layer is prevented from falling off, and a plurality of working procedures for decorating the outer wall are not needed. The external wall panel with the functions of decoration, fire prevention and thermal insulation, which is formed by pre-anchoring and combining the external decoration layer and the fire prevention and thermal insulation layer, is generally called an integrated external wall panel.

The mold removal-free concept: the form-stripping-free form is a form permanently combined with the concrete structure.

The concept of the prefabricated hollow wall body is as follows: the wall body is a form of an assembly type building wall body, also called a superposed wall, and is divided into a double-faced superposed wall and a single-faced superposed wall. The wall plate is prefabricated in a factory, a cast-in-place cavity is reserved, and secondary pouring is completed on a construction site to form the structural stressed wall body. Due to the cast-in-place cavity, the wall body reinforcing steel bars can be conveniently connected up and down, left and right, and the cast-in-place hollow wall body is more excellent than the traditional prefabricated solid wall body.
