High-precision rebar positioning single forming tool for cover plates and application method thereof

Abstract

The invention discloses a high-precision rebar positioning single forming tool for cover plates and an application method thereof. The high-precision rebar positioning single forming tool for cover plates comprises support legs; a bearing frame is mounted above the support legs; a holding frame is mounted on one side of the bearing frame; holding blocks are mounted on the lower inner wall of the bearing frame; each holding block is composed of a first holding block and a second holding block; a limiting block is mounted on each second holding block. The high-precision rebar positioning singleforming tool for cover plates and the application method thereof have the advantages that the holding blocks and the limiting blocks enable rebars to be placed directly on the second holding blocks when users manufacture cover plates; the second holding blocks are provided with limiting clamp grooves at equal intervals, and therefore, users can accurately and quickly place rebars in proper positions when placing the rebars; it can be avoided that poor rebar positioning accuracy and inaccurate positioning of tying / welding joints cause shifting of rebars during intra-formwork pouring; cracking and other problems are avoided for cover plates in later stage; no influence is caused to the service life of each cover plate; the tool herein has high practicality.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a high-precision cover plate steel bar positioning one-time forming mold and a use method. Background technique [0002] The cover plate is a cover made of steel mesh, and the communication, signal, electric power and other professional channels on the high-speed railway are commonly called cable troughs, and cover plates are installed in them. Most of the cover plates are made directly. Made of molds. [0003] In the prefabrication process of the current cover slab project, the positioning of the steel bars is often inaccurate, and the binding / welding joints are not in place, resulting in the phenomenon that the steel bars are out of place during the pouring process, which makes the later cover slabs prone to cracks and breaks. It reduces the service life of the cover plate, and its practicability is not strong; and the production of most equipment is more cumbersome ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-precision cover slab reinforcement positioning one-time forming mold and its use method, which solves the problem of inaccurate reinforcement positioning and binding / welding joints that often occur in the prefabrication process of the current cover slab project. If it is not in place, it will cause the steel bars to move during the pouring process, making the later cover plate prone to cracks, breakage and other problems, which reduces the service life of the cover plate, and its practicability is not strong; and the production of most equipment is relatively It is cumbersome and complicated, and it also needs to spend a lot of production costs, and its economic benefits are low and its practicability is not strong; and when some equipment is used to make cover steel bars, its operation takes a long time and cannot realize assembly line operations, and it also affects workers. High skill requirements, high limitations and low practicality
