Positioning, installing and dismounting tool and method of long-span continuous rigid frame suspension pouring end template

Abstract

The invention discloses a positioning, installing and dismounting tool and method of a long-span continuous rigid frame suspension pouring end template. The tool comprises an overall beam end templatecomprising multiple template units, wherein the template units are divided with positions of reinforcing bar reserved holes as boundaries, each template unit comprises a fixed length steel plate andfixed length angle steel, a reinforcing bar hole groove is formed in the fixed length angle steel, an inner hole-free or few-hole part is the fixed length steel plate, in construction, the fixed length steel plate and the fixed length angle steel are cut according to sizes of the template units, reinforcing bar hole grooves are formed correspondingly, the fixed length angle steel is fixedly installed in a designed beam end line position, the fixed length steel plate is installed, the angle steel and the steel plate are fixed by using short reinforcing bars, so as to penetrate a longitudinal reinforcing bar, the beam end template is reinforced by casting concrete, in dismounting, short reinforcing bars connected at each part of the beam end template are removed, and each template unit is removed independently. Through adoption of the tool and method, construction efficiency of positioning, installing and dismounting of the end template is improved greatly, construction input is reduced,and construction quality is improved.

Description

technical field [0001] The invention relates to the technical field of end formwork design, in particular to a tool and a method for positioning, installing and removing a large-span continuous rigid structure suspended irrigation end formwork. Background technique [0002] With the introduction of the Guiding Opinions on Continuous Beam-related Construction Techniques issued by the Railway Corporation, the construction quality of continuous beams has been significantly improved. In the past, the form of end formwork processed by wood formwork and steel plate can no longer meet the requirements of the continuous beam construction quality in today's society. [0003] The traditional end formwork design method of directly opening holes on the formwork tends to lead to low efficiency of formwork removal construction, high construction risks, and serious deformation of the formwork with less cycle times and more investment. Contents of the invention [0004] In view of the ab...

In the past, the form of wood formwork and steel plate processing end formwork can no longer meet the requirements of today's society for the construction quality of continuous beams

[0003] The traditional end formwork design method of directly opening holes on the formwork will easily lead to low efficiency of formwork removal construction, high construction risk, and severe formwork deformation.
