Single-side self-climbing cantilever formwork and construction method thereof

Abstract

The invention discloses a single-side self-climbing cantilever formwork. The single-side self-climbing cantilever formwork comprises a self-climbing formwork body and a single-side cantilever formwork body. The single-side cantilever formwork body is installed on the self-climbing formwork body, and the self-climbing formwork body drives the formwork body to complete self-climbing. During engineering construction of the single-side self-climbing cantilever formwork, the construction ways and techniques such as an ordinary formwork and a scaffold group, a single-side cantilever formwork, a top formwork and a self-climbing formwork can be effectively replaced; although dam construction can be completed through the formworks in the ways, the effect that construction of towering or extremely-deep single-side concrete projects such as dams, ventilating shafts, slopes, underground factories and hydropower station diversion channels is completed effectively in time-saving and labor-saving modes cannot be achieved due to the fact that technique limitation exists and pertinence of specific projects is not available, installation is difficult, and technical defects exist during construction.

Description

technical field [0001] The invention relates to a building construction formwork device for high-rise or large-depth single-side concrete engineering construction such as dams, ventilation shafts, side slopes, underground powerhouses, diversion channels of hydropower stations, etc., and belongs to the technical field of building construction. Background technique [0002] Among the existing building formwork, there are various formwork structures such as ordinary formwork, self-climbing formwork (self-climbing formwork, cantilever formwork, etc.), which are applied to different construction buildings according to their characteristics. Self-climbing formwork usually adopts hydraulic or electric climbing, and is mainly used in cast-in-situ concrete structural projects such as full shear wall structures of high-rise and super high-rise buildings, frame structure core tubes, large columns, and bridge piers. [0003] One-sided cantilever formwork is also called one-side climbing...

AI Technical Summary

Problems solved by technology

[0005] In the construction of large-volume concrete engineering structures such as dams, building basement walls, and bridge anchorages, ordinary formwork plus scaffolding groups, single-sided cantilever formwork, or self-climbing formwork are generally used to complete the construction. Although these forms of formwork can also complete the project Construction, but due to technical limitations and untargeted special projects, it is impossible to save time and effort to effectively complete the one-sided construction of the project. The concrete volume is too large, and it is difficult to install the inner tie rods. The technical defects in the construction lead to construction Low efficiency, low flexibility, inconvenient operation, low apparent quality of poured concrete, etc.
