Bench formwork system used for pipe gallery roof and early dismounting method of early-dismounting formwork

Abstract

The invention provides a bench formwork system used for a pipe gallery roof and an early dismounting method of an early-dismounting formwork. The system comprises the early-dismounting formwork and alater-dismounting formwork which are in butt joint through a seam splicing device; a butt joint space is formed between the butt joint positions of the early-dismounting formwork and the later-dismounting formwork; reinforcement strips are formed at the lower portions of the butt joint positions of the early-dismounting formwork and the later-dismounting formwork; the seam splicing device comprises a seam splicing connection board arranged in the length direction of the butt joint space, at least one suspender arranged in the butt joint space in a penetrating mode, and limiting parts detachably installed at the bottom ends of the suspenders and abutting against the reinforcement strips; the two sides of the seam splicing connection board are in lap joint with the upper surfaces of the early-dismounting formwork and the later-dismounting formwork; the top ends of the suspenders are connected to the seam splicing connection board; first lines are formed on one side of each limiting partand arranged in the length direction of the butt joint space; and second lines matched with the first lines are formed on one side of each reinforcement strip. The bench formwork system used for the pipe gallery roof and the early dismounting method of the early-dismounting formwork solve the problems that formworks are difficult to dismount and roofs are prone to being damaged when the formworksare dismounted by a traditional formwork early dismounting process.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an early dismantling method for a table formwork system used for the roof of a pipe gallery. Background technique [0002] At present, the roof construction methods of urban underground comprehensive pipe corridors are mainly traditional wood formwork loose assembly and traditional steel formwork assembly. These two construction methods not only have slow progress, high cost, and unsatisfactory forming quality, but also the horizontal transportation of formwork is inconvenient. In order to improve the construction progress and shorten the turnover period of the formwork, the traditional early demolition process of the wooden formwork is used. The early demolition process is to remove all the formwork and retain the support rods. When using this early demolition process to remove the formwork, it is necessary to knock the formwork vigorously to remove the formwork du...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects existing in the prior art, an early dismantling method for the table formwork system used for the roof of the pipe gallery is provided to solve the difficulty of removing the formwork during the removal of the formwork in the traditional formwork early dismantling process, which is easy to cause the roof damage problem
