Exterior wall structure prefabricated block and exterior wall structure prefabricated construction method

Abstract

The invention discloses an outer wall structure prefabrication block which comprises a prefabrication block body and a supportive frame. The prefabrication block body is of a continuous fabrication regular structure. A shape face for decorating an outer wall is arranged on a side face of the prefabrication block body. The supportive frame is fixedly installed on a back opposite to the shape face. The invention further discloses an outer wall structure prefabrication building method which includes the following steps. Firstly, a steel framework for installing the outer wall structure prefabrication block is manufactured on the outer wall. Secondly, according to a preset arrangement manner, the outer wall structure prefabrication block is hung on the steel framework in an arranged mode. After the outer wall structure prefabrication block is adjusted to be in place, the supportive frame is fixedly connected with the steel framework. By arranging the outer wall structure prefabrication block to be of the continuous fabrication regular structure, prefabrication blocks can be conveniently fabricated. By arranging the supportive frame, the prefabrication block bodies can be conveniently fixed on the outer wall. As the prefabrication block bodies are of regular structures, the prefabrication block bodies can be exchanged and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of building structural components, and in particular relates to a prefabricated block of an exterior wall structure and a prefabricated construction method for constructing an exterior wall structure by using the prefabricated block of the exterior wall structure. Background technique [0002] In tunnel construction, tunnel end wall treatment has always been a difficult problem for highway landscape modeling. At present, methods such as wall painting, GRC plastic stone modeling and hanging decorative surfaces are generally used for landscape modeling of tunnel end walls, and the shape of end walls The construction is aesthetically optimized. Among them, GRC plastic stone and hanging decorative materials have good durability and are widely used, but the method of hanging decorative materials is easy to fall off, causing safety hazards to driving, so its application is limited. [0003] Although the current m...

Problems solved by technology

[0004] 1) Inconvenient construction: Due to the aesthetic needs of the exterior wall structure, the shape and structure of the existing panels used to construct the exterior wall structure are irregular. During the construction process, professional guidance is required to complete the assembly of each panel, resulting in inconvenience in construction and construction. low efficiency;

[0005] 2) Inconvenient maintenance: Due to the irregular shape and structure of the boards, when one of the boards is damaged, it cannot be replaced and repaired with other boards immediately, and a replacement board with the same shape and structure as the damaged board must be remade, resulting in high maintenance costs and time-consuming
