Formwork assembling and disassembling system for side wall concrete pouring and working process thereof

Abstract

The invention discloses a formwork assembling and disassembling system for side wall concrete pouring and a working process thereof. The formwork assembling and disassembling system comprises envelop enclosures arranged on the side walls of a foundation pit and side wall pouring formwork sets arranged on the inner sides of the envelop enclosures. Each side wall pouring formwork set comprises a first formwork and a second formwork. A side wall pouring part is formed in the gap between each first formwork and the corresponding second formwork. At least one formwork assembling and disassembling device for assembling and disassembling the first formworks on the ground is arranged between each envelop enclosure and the corresponding first formwork. The second formworks are supported by a side wall trolley. The working process comprises the steps that supporting cross rods and transmission rods are installed on the first formworks, the first formworks are hoisted in place, and transmission rod screw rods are adjusted, so that the first formworks are fastened through the supporting cross rods. Operators only need to assemble and disassemble the first formworks on the ground and do not need to enter the bottom of the foundation pit. The formwork assembling and disassembling system for side wall concrete pouring and the working process thereof are especially suitable for assembling and disassembling outer side formworks in a narrow space, and accordingly the cost, progress and quality of engineering construction can be controlled very well.

Description

technical field [0001] The invention relates to a formwork support and removal system for concrete pouring of side walls and its working process. Background technique [0002] Usually, the formwork is installed on the outside of the shear wall or the foundation cap of the underground project. It is necessary to reserve about 1 meter as the operating space for the formwork installation and construction during the excavation of the earthwork and the construction of the enclosure structure. In special cases, in order to reduce the excavation and backfilling of the earthwork The volume, or the structural size is changed, resulting in a narrow space for the installation and operation of the outer formwork, and the operator cannot enter the bottom for installation and formwork removal operations. The specific manifestations are as follows: [0003] 1) During the construction of underground engineering or foundation caps, underground pipe trenches, ditches and other structures, whe...

[0004] 2) In many cases, construction techniques such as steel sheet piles and bored piles will cause the support surface to be uneven and offset due to geological reasons. The space between the support surface and the structure to be poured with concrete is less than 50cm, resulting in There is no working space for the formwork installation during the construction of structural components, which makes it difficult to install and remove the formwork

[0005] 3) For economical reasons, in order to minimize the amount of earthwork excavation and backfilling, the construction party will try to reduce the distance between the steel sheet piles, bored piles and the structure edge, which often causes the space for formwork installation and removal to be insufficient for workers to operate on the working surface Require

[0006] 4) In addition, due to the difficulty of relocating underground pipelines or design changes during the construction process, there will also be cases where formwork needs to be erected and removed in a narrow space

In this way, the cost of support and excavation will be increased, and the construction period will be delayed.
