Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure installation, and in particular relates to a steel structure butt joint auxiliary device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. I-beams are often used as frame materials for steel structure connections.

[0003] When existing I-beams are welded or bolted at high altitudes, they are usually hoisted with hoisting equipment and then stabilized manually. However, due to wind force and the gravity of the steel structure itself, the I-beams are prone to shaking or tilting during the welding process, which affects the accuracy and quality of the welded joints and may also pose a threat to the safety of the welders. At the same time, if the steel structure shakes during the welding process, the weld may have defects such as unevenness, cracks, slag inclusions, etc., which will affect the overall strength and durability of the steel structure.

[0012] By adopting the above technical solution and setting of the moving part, the sliding rod can drive the stabilizing frame to move its position, thereby avoiding the setting of the stabilizing frame from affecting the welding of its steel structure.

[0013] Optionally, the adjusting member comprises a pair of adjusting screws mounted on the side walls of the stabilizing frame, and opposite ends of the pair of adjusting screws are respectively fixedly connected with abutment seats.

[0016] By adopting the above technical solution and setting the locking piece, the top cover and the stabilizing frame are firmly fixed, thereby preventing the top cover from being lifted up during the driving process of the electric push rod.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. By setting up a mounting seat, with the cooperation of an electromagnet, the mounting seat and the steel structure are magnetically fixed, and the stabilizing frame is simultaneously driven to support the horizontally placed steel structure, and the electric push rod is started, and the electric push rod drives the pressure plate to move down to squeeze the horizontally placed steel structure, and then the adjustment screws on both sides are rotated to stabilize the horizontally placed steel structure, so that the horizontally placed steel structure is not easy to deviate during the welding process, and no manual assistance is required for stabilization, thereby improving the welding quality; 2.
