Welding supporting table for joints

Abstract

The invention relates to a welding supporting table for joints, the welding supporting table freely detachably supports joints formed by connection of a beam installation part and a wall surface of a joint core plate in spot welding, thereby keeping the joint at a pair of rotary transposers, the welding supporting table comprises: a mounting part disposed at a position between the pair of rotary transposers in a mode that a plurality of joints are mounted on a same plane; a supporting mechanism disposed on the mounting part and performing support of the beam installation part of the joints; a column-shaped part respectively disposed at two ends of the mounting part, and kept in a free detachable way via fixed clamping tools disposed at the inner sides of annular parts of the rotary transposers. According to the composition, joint positioning of current rotary transposers can be easily performed, a plurality of joints can welded, and original welding operation zones of the rotary transposers can be effectively used.

Description

Technical field [0001] The invention relates to a welding support table for a joint that can use an existing rotary indexer to complete a joint welding operation. Background technique [0002] Generally, steel frame columns such as columns, SRC columns, and round pipe columns of steel frame buildings are manufactured by welding joints and long columns made in advance into a continuous structure in the longitudinal direction. In addition, when welding the steel frame column, a pair of rotary indexers are used to hold the two ends of the steel frame column on the rotary indexer, and it can be moved along the length of the steel frame column. The welding device of the company performs this operation. [0003] For this reason, the welding of columns for steel structures needs to make preparations for joints. The joint used here usually welds a circle of cross-section plates (separators) on both ends of a short column (column) with the same cross-section as the long column to make the...

AI Technical Summary

Problems solved by technology

[0006] The existing rotary positioner cannot be used with the conventional joint welding device, and a dedicated positioner needs to be remanufactured

In addition, a transposer is required for one joint, and the structure is also very complicated, so that the cost is too high relative to the welding work for one joint, and there is also a problem that each joint must be fixed and welded. Operation, disassembly operation, so the operation efficiency is not high

[0007] In addition, the conventional welding equipment for joints does not use the existing rotary positioner, so there is a problem that it uses a special equipment for joint welding, and it is necessary to secure its use place.
