Tightening device used for joint between steel plates during steel structure welding

Abstract

The invention relates to a tightening device used for a joint between steel plates during steel structure welding. The tightening device comprises a door-shaped frame, a tray rack, a lifting jack anda rib plate perpendicularity regulating mechanism, wherein two fixed supporting legs of the door-shaped frame are fixedly connected to steel plates; the tray rack is in sliding connection on two fixedsupporting legs of the door-shaped frame in a vertical direction; the lifting jack is placed between the tray rack and a limiting top plate of the door-shaped frame; the lifting jack jacks the tray rack to generate downward acting force, so that the tray rack can press a rib plate which needs to be perpendicularly welded with the steel plates; and the rib plate perpendicularity regulating mechanism is arranged on the two fixed supporting legs for clamping the rib plate and regulating perpendicularity of the rib plate. The tightening device used for the joint between steel plates during steelplate welding can realize effective fitting between the steel plates and the rib plate, tightens the joint between the rib plate and the steel plates, avoids uneven welding seams, and meets quality requirements in a construction process.

Description

technical field [0001] The invention relates to the technical field of steel structure construction, in particular to a joint tightening device used for steel structure welding between steel plates. Background technique [0002] In the current construction field, with the continuous innovation of technology, many bridge constructions and some structures of industrial plants are designed with steel structures to meet the requirements of lightweight structures, convenient installation and disassembly, and convenient construction. In the construction process, it is often necessary to blank the whole steel plate raw material first, and then carry out the assembly and welding process. According to the principle of construction technology, usually when some steel structures are manufactured, several ribs or ribs perpendicular to it will be welded on a flat main structural steel plate to increase the three-dimensional rigidity of the steel plate and ensure that it is combined with ...

AI Technical Summary

Problems solved by technology

[0003] In view of this, the object of the present invention is to provide a joint tightening device between steel plates for steel structure welding, which can realize the effective bonding of ribs and steel plates in steel structure welding construction, to solve the problems in the prior art. When the rib plate and the steel plate are welded, due to the local deformation of the steel plate, the width of the joint between the steel plate and the rib plate is different, which affects the flatness of the welded steel plate.
