Anti-floating inverted arch formwork system

Abstract

The invention discloses an anti-floating inverted arch formwork system. The system comprises an inverted arch formwork and further comprises a supporting framework located above the inverted arch formwork, a plurality of connecting parts are arranged between the supporting framework and the inverted arch formwork, and the connecting parts are arranged at intervals in the width direction and the length direction of the inverted arch formwork. The supporting framework is provided with a plurality of lifting components arranged in the vertical direction. The system has the advantages of being simple and reliable in structure, beneficial to reducing labor intensity, good in anti-floating effect, capable of being repeatedly used and the like.

Description

technical field [0001] The invention relates to equipment for tunnel construction, in particular to an anti-floating inverted arch formwork system. Background technique [0002] In tunnel construction, the level of mechanized construction is getting higher and higher, and the process organization in each area is also relatively professional. In the inverted arch filled concrete construction area, the promotion and use of self-propelled inverted arch trestle makes the construction in this area safer and more efficient. The popularization and use of the integral inverted arch formwork has realized the rapid construction of the inverted arch, saved the assembly and dismantling of the formwork, greatly reduced the labor intensity of the workers, and improved the efficiency and quality of the inverted arch construction. The combination of self-propelled inverted arch trestle and integral inverted arch formwork meets the mechanization, automation, generalization and standardizati...

Problems solved by technology

[0003] At present, during the concrete pouring construction of the inverted arch layer, since the inverted arch formwork is not fixed, and the concrete has certain fluidity and impact, pouring a large amount of concrete will cause the inverted arch formwork to float up and run away, which seriously affects the forming of the inverted arch. quality

The commonly used reinforcement scheme for inverted arch formwork is to use multiple anchors. In actual construction, the formwork is pulled down more often, and the anchors need to be installed at the bottom when pulled down. The construction is cumbersome, the cost is high, and the controllability is poor. The two ends of the formwork are reinforced, and the reinforced anchor points cannot be reused. At the same time, they also need to be supported by the side. The support point is relatively single, the labor intensity is high, and the support effect is average.
