Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, in particular to a positioning structure for steel structure welding. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect the components or parts. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structure welding refers to the use of hot-rolled steel (angle steel, I-beam, channel steel, steel pipe, steel plate, etc., cold-formed thin-walled steel) and steel cables as basic elements. After being connected according to certain rules to form basic components through welding, bolts or rivet connections, the basic components are irregularly connected by welding, bolts or rivets to form a structure that can withstand external loads as a steel structure.

[0003] However, when vertically welding the connecting plate in the channel steel, the operator needs to draw a positioning line in the steel channel in advance, and then when placing the connecting plate on the positioning line, weld a point between the connecting plate and the channel steel in the middle part of the bottom end of the connecting plate, and then use a square to measure whether the connecting plate and the two sides of the channel steel are vertical. If not, use a tool to knock the connecting plate to rotate it until the connecting plate is vertical, and weld two points on both sides of the bottom end of the connecting plate and the contact with the channel steel for positioning, and then measure again whether the connecting plate and the bottom end of the channel steel are vertical, knock the connecting plate again to keep the connecting plate vertical, and then weld two points at the contact between the two ends of the connecting plate and the channel steel, so as to perform the positioning operation between the connecting plate and the channel steel, and finally weld the connecting plate in the channel steel. This positioning operation is relatively complicated. In order to facilitate the vertical positioning of the connecting plate in the channel steel for welding, a positioning structure for steel structure welding is provided. Utility Model Content
