Problems solved by technology

In the case of traditional cast-in-place wall panels, there is no upper floor as a platform, so construction workers must climb to a certain height to operate cast-in-place. The construction is difficult and dangerous, and the construction period is long and the efficiency is low.

Embodiment Construction

[0015] Such as figure 1 As shown, the two sides are concrete non-demolition formwork with small-diameter and small-pitch steel wire mesh as the skeleton, and the two pieces of non-demolition formwork are hooked with the steel bars 4 shown in the figure to form a stable cast-in-place mold. During cast-in-place construction, just pour concrete into the space in the middle of the mold, and it is not necessary to remove the mold after forming.

[0016] figure 2 The schematic diagram of the reinforced grid is shown, and the two steel grids are hooked with thicker steel bars to form the skeleton of the cast-in-place concrete mold.

[0017] Generally, steel formwork and wood formwork must be dismantled after the components are formed and permanently fixed, and reused in the next construction. In this construction method, a floor must be cast twice, once for wall panels and once for floor slabs. This brings up many problems. In order to solve these problems, a formwork-fre...

Abstract

The invention discloses a steel wire net rack demolition-free formwork system and a manufacturing method thereof, wherein two demolition-free formworks are adopted and hooked up through rebars, and concrete is cast on-site between the two formworks, so as to jointly form a wall body; and the demolition-free formwork has the structure that two-layered small-diameter small-interval rebar meshes are welded through three-dimensional oblique-inserting rebars into a spatial net rack, the spatial net rack is arranged in a mold, and a layer of thin concrete is cast in the mold to be solidified and formed into the formwork. The popularization and application of the steel wire net rack demolition-free formwork system saves resources, is environment-friendly, reduces the formwork cost, accelerates the construction speed, improves the efficiency, and is a significant innovation for the building construction.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a formwork-free system of a steel wire grid frame and a manufacturing method thereof. Background technique [0002] Building formwork plays a very important role in the process of building construction. In the process of building construction, many components need to be cast-in-place. When the cast-in-place components are formed, they must be supported by formwork. Now the general formwork is wood formwork or steel formwork. Making formwork requires a certain cost, and the building is built layer by layer. During the construction process, the formwork needs to be installed, dismantled, and transferred, and the workload is heavy. In prefabricated construction, the wallboard is generally supported first, then the formwork is supported vertically, then the vertical components are poured, the vertical component molds are removed, the laminated slabs are placed, and...
