Problems solved by technology

[0002] At present, in the field of building construction, conventional wooden formwork is used to block the post-pouring belt. The flow of concrete overflows the formwork. It is time-consuming and labor-intensive, and the dismantled wooden formwork is not complete. If the external force is too large, the wooden formwork may break in the concrete, which will seriously affect the quality of the post-casting belt. The existing formwork support method increases the construction cost and reduces the construction quality. , low work efficiency

Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the embodiment of the present invention is further elaborated: post-casting belt exempts formwork parts from being dismantled, and it is made formwork body 7 by rectangular cross-section reinforcing steel skeleton, and A-type threaded steel 1, B-type threaded steel 2 and A-type threaded steel 2 are set on formwork body 7 Rebar connecting rod 4 is welded and fixed, and placed under steel mesh sheet 5; tie bars 3 are installed on one side of B-shaped rebar 2, and cast-in-situ concrete 6 is poured into formwork body 7.

[0014] The specific post-casting strip free formwork parts, the A-type rebar and the B-type rebar are welded and fixed in a V-shape in a dislocation and equidistant arrangement.

[0015] The specific post-casting strip free formwork parts, A-type rebar is long strip, 8-30cm long, 1.5-3cm wide.

[0016] The specific post-casting strip free formwork parts, the B-type rebar is cylindrical, 2.8-5.5 in length a...

Abstract

The invention aims to provide a formwork-detachment-free device for a post-cast strip. According to the formwork-detachment-free device, a formwork body is formed by a steel reinforcement framework with a rectangular cross section. A-type threaded steel, B-type threaded steel and a reinforcing steel bar connection rod are arranged on the formwork body, combined and fixed through welding and placed below a steel wire screen. A tie bar is installed on one side of the B-type threaded steel and cast-in-place concrete is poured into the formwork body. Multiple times of trail show that the formwork-detachment-free device has the advantages that an original structure is changed, overflowing of the concrete is effectively prevented in the pouring process, labor and force are saved in the process of cleaning, waste is completely eradicated, the pouring quality is not influenced, an on-site construction procedure is simplified, labor force is lowered, waste reinforcing steel bars are fully used for manufacturing, materials are conveniently obtained, cost is reduced, practicability is high, cost is low, operation is safe and convenient, and the formwork-detachment-free device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of building construction components, in particular to a formwork device for post-casting strips without dismantling. Background technique [0002] At present, in the field of building construction, conventional wooden formwork is used to block the post-pouring belt. The flow of concrete overflows the formwork. It is time-consuming and labor-intensive, and the dismantled wooden formwork is not complete. If the external force is too large, the wooden formwork may break in the concrete, which will seriously affect the quality of the post-casting belt. The existing formwork support method increases the construction cost and reduces the construction quality. , low work efficiency. Contents of the invention [0003] The object of the present invention is to provide a dismantling-free formwork device for post-casting tape, which has the function of dismantling-free, saves time and time, and improves work eff...
