Positioning device for welding road bridge pile foundation reinforcement cage

Abstract

The invention discloses a positioning device for welding a road bridge pile foundation reinforcement cage, and relates to the technical field of welding. The positioning device includes an upper outerring, a lower outer ring, an inner ring, an upper shield, a lower shield and a fixed seat. According to the positioning device for welding the road bridge pile foundation reinforcement cage, the mainrib of the reinforcement cage is positioned and fixed by clamping the upper outer ring, the lower outer ring, and the inner ring, the reinforcement cages with different main rib separation distancesare located by arranging a plurality of circular arc grooves on the inner ring, different main rib separation distances are quickly positioned by arranging scales on the sides of the upper outer ringand lower outer ring, and the work efficiency is improved; through the rotatable separate mode of the upper outer ring and lower outer ring, the main rib just needs to be slightly raised during the positioning, thereby reducing the labor intensity; the movable fixed seat is arranged to cooperate with the upper outer ring or the lower outer ring, the reinforcement cage can be directly pushed to theconstruction site after the welding is completed, and the working efficiency is greatly improved; and the positioning device is protected by adding the shields, and effective, thereby effectively preventing the damage of high temperature welding slags to the positioning device.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a positioning device for welding of road and bridge pile foundation reinforcement cages. Background technique [0002] The pile foundation of the road and bridge is filled with concrete to form a cylindrical foundation construction pile foundation. Its function is to transfer the weight of the building to the ground through the pile foundation to ensure the stability of the building. The steel cage is used as the skeleton of the pile foundation, and its connection must be stable. , there must be no loosening phenomenon, otherwise, the stress of the concrete inside the excavated pile will be eliminated due to the loosening of the steel bar, which will further lead to a decrease in the force capacity of the excavated pile, which will affect the project quality and construction progress. Therefore, the connection of the reinforced cage of the excavated pile is very impor...

Problems solved by technology

[0003] The purpose of the present invention is to provide a positioning device for the welding of reinforcement cages of road and bridge pile foundations. The device fixes the main reinforcement of the reinforcement cage through the clamping of the outer ring and the inner ring, and solves the difficulty and inaccurate positioning of the main reinforcement of the reinforcement cage. The problem of stability, by setting a number of arc grooves on the inner ring, the spacing can be adjusted when positioning the main reinforcement, which can meet the positioning requirements of the reinforcement cage with different main reinforcement spacing, and solve the problem of single positioning of the main reinforcement by the existing positioning equipment. The scales on the sides of the outer ring and the lower outer ring greatly facilitate the rapid positioning of the reinforcement cages with different main bar spacings, and effectively improve work efficiency; through the rotatable separation of the upper outer ring and the lower outer ring, positioning When the main reinforcement is used, the main reinforcement can be lifted slightly, which greatly improves the difficulty of the work and reduces the work intensity; by setting the fixing seat to cooperate with the upper outer ring or the lower outer ring, the fixing of the steel cage is further strengthened; The welding operation is carried out in the workshop, and the steel cage can be directly pushed to the construction site after completion, which greatly increases the work efficiency; the invention also protects the positioning device by adding a protective cover, which effectively prevents damage to the device by high-temperature welding slag
