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

Abstract

The invention discloses a steel mesh formwork for cast-in-place lightweight concrete walls with simple construction operation and guaranteed construction quality. It has a main back corrugated (1) and a secondary back corrugated (2). A steel wire mesh (3) is fixed on the inner surface of the back flute (2), and needle-punched cloth (4) is covered on the steel wire mesh (3). The construction process of steel mesh formwork for cast-in-place lightweight concrete walls is carried out as follows: install the non-demolition-free keel metal mesh (5) for cast-in-place lightweight concrete walls; cover the needle-punched cloth (4) on the non-demolition keel on the metal mesh (5); fix the steel wire mesh (3) on the needle-punched cloth (4) by using the main back flute (1) and the secondary back flute (2); pour lightweight concrete (6); remove the steel mesh ( 3) and acupuncture cloth (4); wall maintenance.

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
