Concrete pouring formwork and construction method thereof

Abstract

The invention discloses a concrete pouring formwork and a construction method thereof. The concrete pouring formwork comprises a plurality of formwork main bodies which are sequentially connected; theformwork main bodies comprise bases which can be lifted and moved; the bases are fixedly connected with top arching frames located above the corresponding bases through a plurality of upright columns; the two sides of the top arching frames are hinged with side wall arching frames correspondingly; a plurality of detachable jack screws are connected between each side wall arching frame and the upright column closest to the corresponding side wall arching frame; and a plurality of steel templates are spread on the top arching frames and the side wall arching frames. Frame erecting is rapid, nofrequent disassembly or assembly is required, overall movement and moving in place can be carried out, the concrete surface evenness and the appearance size are easy to control, and the labor and timeare saved. Demoulding is rapid, and the demoulding can be completed simply by disassembling the jack screws and lowering the height of the concrete pouring formwork. Environment protection is facilitated, by adopting the construction method, the frame erecting and the demoulding can be carried out without frequently disassembling the concrete pouring formwork or the steel templates, sundries on aconstruction site are few, an operating space is wide, a rod is clear, and civilization construction is facilitated.

Description

technical field [0001] The invention relates to the technical field of concrete pouring formwork, in particular to a concrete pouring formwork and a construction method thereof. Background technique [0002] In the construction of underground engineering, due to the limitation of the site, structure and other environment and use functions, its cross-section forms are becoming more and more diverse, especially the locations of auxiliary works such as cross passages, entrances and exits are scattered and messy, and the cross-section changes frequently and multi-terminal; this gives The construction of molded concrete has added a lot of difficulty. The lining trolley is bulky and expensive, and cannot be turned in curved sections and cannot stand in sloped sections. Can't even think about it. [0003] The traditional method is to use shelf tubes, steel arches, steel formwork, and artificial formwork. Traditional methods have the following shortcomings: [0004] 1. Slow form...

AI Technical Summary

Problems solved by technology

[0004] 1. Slow formwork: Every time a cycle of concrete is poured, it is necessary to disassemble the shelf pipes, steel arches, and steel formwork, and then need to be erected again; and the operating space is narrow, and the integrity of the formwork and the flatness of the formwork are difficult to control. Time-consuming

[0005] 2. Slow demoulding: After removing the steel arch, remove the steel formwork piece by piece. Since the steel formwork is bonded together in the concrete arch ring, if one piece is removed, the other steel formwork may fall into pieces or fall completely. fall, resulting in severe deformation of the steel formwork, which poses a serious safety hazard

[0006] 3. Not environmentally friendly: The dismantled shelf tubes, steel arches, steel formwork and other spare parts are large in size and miscellaneous in variety, requiring a lot of labor to clean, sort, and stack, and occupying limited operating space. The construction site is very messy
