Steel net template for cast-in-situ light concrete wall body and construction technology

Abstract

The invention discloses a steel net template for a cast-in-situ light concrete wall body, wherein the steel net template is easy in construction operation and the construction quality can be ensured.The steel net template comprises a main back square beam (1) and a secondary back square beam (2). The inner side surfaces of the main back square beam (1) and the secondary back square beam (2) are all fixedly provided with steel wire nets (3). Each steel wire net (3) is covered with a needling cloth (4). A construction technology of the steel net template for the cast-in-situ light concrete wallbody comprises the following steps that a free-demolishing keel metal net (5) for the cast-in-situ light concrete wall body is arranged; each needling cloth (4) is covered on the free-demolishing keel metal net (5); each steel wire net (3) is fixed on the corresponding needling cloth (4) by means of the main back square beam (1) and the secondary back square beam (2); light concrete (6) is casted; the steel wire nets (3) and the needling clothes (4) are removed; and the wall body is cured.

Description

technical field [0001] The invention relates to the construction field, in particular to a steel mesh formwork for cast-in-place lightweight concrete walls and a construction process that is simple in construction operation and can ensure construction quality. Background technique [0002] The cast-in-place lightweight (foam) concrete wall has the characteristics of light weight and low elasticity, heat insulation, fire resistance and shock absorption, high integrity and durability, and good waterproof effect, and has been widely used in the construction field. The existing construction technology is to add foam to the slurry made of cement, aggregate, admixture, admixture and water to make lightweight concrete, and then pour and install the lightweight concrete on the building frame. Inside the wall formwork, it is formed after demoulding and curing. Existing wall formwork includes wood formwork, steel formwork, plastic formwork, aluminum formwork and steel-wood composite ...

AI Technical Summary

Problems solved by technology

Existing wall formwork includes wood formwork, steel formwork, plastic formwork, aluminum formwork and steel-wood composite formwork, etc. Although the materials are different, all formwork is a non-mesh flat plate, which needs to be manually brushed on the formwork before pouring Apply a release agent that is easy to release, which is labor-intensive and pollutes the environment

However, due to the impermeability of the formwork, the moisture in the lightweight concrete cannot evaporate in time, and the uneven application of the release agent by manual brushing will cause local peeling of the wall surface during demoulding. The treatment of the wall surface not only has the same problem of polluting the environment, but also takes time and effort, increases the cost of raw materials, and increases the construction cost

Although the surface of the wall treated with the interface agent is smooth, its sound insulation effect is greatly reduced
