Process for quickly disassembling and assembling integrated segmental beam steering block formwork

Abstract

The invention relates to the technical field of segmental beams, in particular to a process for quickly disassembling and assembling an integrated segmental beam steering block formwork, which comprises the following steps of: installing a bottom corner outer formwork, installing a top end outer formwork, then installing a movable inner formwork in a space formed by the bottom corner outer formwork and the top end outer formwork, and filling the space with a steel reinforcement framework. The movable inner formwork is fed into the outer formwork cavity through the C-shaped inner formwork, the movable inner formwork is fixed into the outer formwork cavity through the hydraulic system, then the C-shaped inner formwork retreats, and finally the outer side plate is installed. According to the process, a segmental beam can be integrally formed, and modular splicing is not required. The unsafe state of unsafe behaviors of people is completely eradicated, potential safety hazards are eliminated, the effect is high, the mold closing time is shortened, the demolding effect of the precast beam section is ideal, and the requirement of the construction technology is met.

Description

technical field [0001] The invention relates to the technical field of segmental beams, in particular to a quick disassembly and assembly integrated segmental beam steering block formwork process. Background technique [0002] With the development of transportation construction, the application level of bridge construction has improved, and bridge construction has a new construction method. Compared with the traditional construction method of cast-in-place box girder with full-bore supports, segmental beams are more widely used at present. The so-called segmental beam splicing, the so-called segmental beam refers to the division of the entire span beam in the actual project into several segments, and through the reserved channel design, the steel strand crosses the entire collapsed beam through the post-tensioning method Connect the segmental beams into a whole and give the beam body prestress. At present, the production process of the segmental beams is mainly the short-lin...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing segmental beam formwork does not have the formwork structure of the movable block of the segmental beam. After the pouring is completed, the movable block needs to be installed again. During the installation process, the gantry crane will appear crooked and inclined. And the phenomenon of lifting injury, and the effect of manual mold clamping is low, the structure of the segmental beam is unstable, and the demoulding effect of the prefabricated beam section is not ideal
