Formwork assembly with adjustable t-beam flange plate width and method of use

Abstract

The invention discloses a template assembly capable of adjusting the width of a T-shaped beam flange plate and an application method of the template assembly. The template assembly capable of adjusting the width of the T-shaped beam flange plate comprises a sizing steel template for beam rib forming and flange plate edge templates for flange plate forming. The sizing steel template comprises a groove body part and installing parts arranged on the two sides of the top end of the groove body part. The flange plate edge templates are detachably fixed to the installing parts through magnet adsorption limiters. According to the provided template assembly capable of adjusting the width of the T-shaped beam flange plate and the application method of the template assembly, the width of the flangeplate can be flexibly, simply and conveniently adjusted, sizing steel template damage due to repeated steel bar welding and positioning is reduced, meanwhile, the construction intensity is lowered, the work efficiency is improved, and the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a formwork assembly with adjustable width of a T-beam flange plate and a use method thereof. Background technique [0002] At present, my country's highways, high-speed railways, and stations basically involve prefabricated T-beam sub-projects. Usually, when the bridge is located on the horizontal bending line of the line, due to the existence of the bending radius, there is a gradual change in the width of the T-beam of the corresponding span, or some T-beams in the design have different lengths, and the width of the flange plate is also different. Adjust the position of the edge plate template. The accuracy of the width of the flange plate is very important, especially on the edge beam, the control of the protective layer of the steel bar is strictly required, and if the error is too large, it is difficult to guarantee the protective layer of the steel bar. At the...

Problems solved by technology

In the traditional prefabricated T-beam prefabrication process, for the situation where the width of the flange plate needs to be adjusted, the supporting ribs are usually temporarily welded on the shaped steel formwork to adjust the position of the side formwork of the flange plate to realize the gradual change in the width of the flange plate. Different types of T-beams The gradient parameters are different, so the position of the side formwork of the flange needs to be adjusted multiple times. The reciprocating welding and positioning of the steel bars greatly affects the flatness of the formwork, which in turn affects the appearance of the prefabricated T-beam. At the same time, it consumes labor and time, affecting the construction efficiency. Can not accurately control the width of the flange plate, can not adapt to large-scale construction, there is no effective way to adjust the width of the flange plate simply and flexibly
