Template supporting device of diaphragm plate of T-shaped bridge surface and template supporting and removing method

Abstract

The invention discloses a template supporting device of a diaphragm plate of a T-shaped bridge surface and a template supporting and removing method. The problems that the template supporting device is easily damaged and the repeating utilization factor of the template supporting device is low in the traditional template supporting technology of the diaphragm plate in erection of a dual-line T-shaped bridge are solved. The template supporting device comprises a front lateral template (19), a rear lateral template and a bottom template (18), which are respectively arranged on a diaphragm gap (5), wherein a front underpinning steel angle and a rear underpinning steel angle are respectively arranged on the bottom surfaces of the front and rear sides of the bottom template (18); hanging holes are formed in the underpinning steel angles; crossed hooks are connected with the underpinning steel angles through tighteners in a hooking manner; two hanging holes are also respectively formed in the left and right ends of the underpinning steel angles, and connected with tips of embedded bars of two T-shaped bridges in a wet joint (6) through the hooks and the tighteners respectively in the hooking manner. By adopting the template supporting device disclosed by the invention, no support rack is arranged on the bridge surface, so that the bridge surface is prevented from being crushed and damaged by vehicles; the repeated usage rate of the templates is high; the construction efficiency is improved.

Description

technical field [0001] The invention relates to a supporting formwork device used in bridge erection construction, in particular to a transverse partition formed between the lower end partitions of the erected parallel T-shaped beams in the erection of double-line T-shaped beams The formwork supporting device and the formwork removal method thereof before the seam is poured. Background technique [0002] In the erection process of the T-beam bridge, after the erection of the double-line T-beam is completed, reinforced concrete shall be poured between the diaphragms of two adjacent T-beams in parallel to form a horizontally connected diaphragm plate to enhance the strength of the entire bridge body. Before pouring the transverse partitions, the formwork should be set up for the transverse partitions, and then the cement can be poured. The existing formwork support method is to use the hanging formwork, which is to use steel bars or wire ropes to pull the bottom formwork alon...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a T-shaped girder deck system transverse diaphragm formwork support device and formwork removal, which solves the problem of supporting steel pipes or squares existing in the existing formwork support devices for transverse partitions in the erection of double-line T-shaped girders. The wood is easily damaged and the reuse rate of the formwork device is low
