Integral sprayed wall body structure with internal and external molds

Abstract

The invention provides an integral sprayed wall body structure with internal and external molds. The structure comprises a steel mesh and a leaf wall, wherein the steel mesh is used as the parallel internal molds and / or external molds, two internal molds are inside, two external molds are respectively located on both sides of the internal molds, a light steel keel framework connected with the internal molds is arranged between the internal molds, and structural columns / beams are connected to two ends of the light steel keel framework in an assembly mode through connectors; separators are arranged between the internal molds and the external molds, and the separators, the internal molds and the external molds are fixedly connected with each other; the external molds are provided with meshes,a leaf wall material is sprayed on the external molds to form a leaf wall, and the leaf wall material penetrates through the meshes of the external molds to connect and cover the internal molds. According to the structure, the wall body framework has high strength and good embedment between the leaf wall material and the wall body framework, and a flexible connection and a special expansion jointare formed by the wall body and the structural columns / beams, so that the wall body material is controlled inside the expansion joint through the stress caused by the temperature difference change, and the cracking defect of the wall body is effectively overcome.

Description

technical field [0001] The invention relates to an integral sprayed steel mesh wall of a building, in particular to an integral sprayed wall structure with inner and outer molds. Background technique [0002] In order to protect cultivated land, reduce emissions, and protect the environment, the state strictly prohibits the production and use of clay bricks, and vigorously advocates and promotes the use of various new types of wall and wall materials that are energy-saving, emission-reducing, waste-friendly, and environmentally friendly. The country bans sticking, reducing and controlling all kinds of new lightweight wall panels used after various types of masonry. There is a bottleneck that is difficult to overcome due to temperature difference changes after installation, which causes wall panels to deform and crack. For molded walls, only fine slurry can be used to spray and hang on the inner mold net of the steel mesh. However, if the sand particles are fine, they will cr...

Problems solved by technology

The country bans sticking, reducing and controlling all kinds of new lightweight wall panels used after various types of masonry. There is a bottleneck that is difficult to overcome due to temperature difference changes after installation, which causes wall panels to deform and crack. For molded walls, only fine slurry can be used to spray and hang on the inner mold net of the steel mesh. However, if the sand particles are fine, they will crack easily, and if the sand particles are coarse, spraying grout will cause the slurry particles to rebound and fail to stick to the wall. Formwork steel mesh, falling, weak reinforcement on the wall surface layer, coupled with factors such as rigid connection between the wall and the column and beam structure, there is shrinkage of the wall material caused by the temperature difference of the hydraulically brittle hardened material of the wall, and the wall Defects such as serious body cracking
