Special-shaped beam butt welding tool for green building construction

Abstract

The invention relates to the technical field of welding tools, and provides a special-shaped beam butt welding tool for green building construction. The tool can be suitable for special-shaped beams of various specifications, has small damage to the special-shaped beams in the construction process, can smoothly realize butt welding of two special-shaped beams with large deviation, can be repeatedly used, and has a long life cycle. The tool comprises a plurality of traction bolts and two mounting frames, the two mounting frames are connected with a plurality of left traction lugs and a plurality of right traction lugs correspondingly, the traction bolts are arranged in the left traction lugs and the right traction lugs, the two mounting frames are connected with fixing plates and adjusting plates, pressing driving assemblies are mounted between the adjusting plates and the mounting frames, the adjusting plates and the fixing plates are each provided with a plurality of stepped holes, the stepped holes are connected with elastic springs, the stepped holes are connected with limiting plates through adjusting positioning columns, the two mounting frames are connected with connecting external thread rings through internal thread rings, and the two connecting external thread rings are connected through a centering assembly.

Description

technical field [0001] The invention relates to the technical field of welding tooling, in particular to a special-shaped beam butt welding tooling for green building construction. Background technique [0002] As we all know, a green building is a high-quality building that saves resources, protects the environment, reduces pollution, provides people with healthy, applicable and efficient use of space, and maximizes the harmonious coexistence of man and nature within the entire life cycle. Special-shaped beams are usually used in the construction process. The special-shaped beams in some green buildings with large spans need to be butt-welded on site during the construction process. Because it is difficult for the two special-shaped beams to be welded to be positioned by manpower alone, green buildings It is particularly important to propose butt welding tooling for special-shaped beams for construction. [0003] The existing special-shaped beam butt welding tool for green...

Problems solved by technology

[0003] The existing special-shaped beam butt welding tool for green building construction includes two end rings, and a plurality of connection holes are correspondingly opened on the two end rings, and traction bolts are arranged in the connection holes. During the construction process, the two end rings are firstly connected The rings are respectively welded at the ends of the two special-shaped beams that need to be butt welded, and then the drawing bolts are inserted into the corresponding connection holes on the two end rings, and the nuts are threaded on the drawing bolts. The two end rings are close to each other, and the two end rings are close to each other to drive the two special-shaped beams to approach each other until the relative position between the two special-shaped beams is suitable for welding. After welding, stop adjusting and start welding. After the welding is completed, the traction Bolts are removed, and the end ring is cut off or knocked off. Although the above-mentioned prior art scheme can realize the butt welding of two special-shaped beams, it will inevitably cause damage to the special-shaped beam due to the need to weld the end ring on the special-shaped beam. The impact of other follow-up construction after the butt welding of special-shaped beams is completed, and when the deviation between the two butt-joined special-shaped beams is large, and the traction bolts cannot be penetrated between the two end rings welded on the special-shaped beams, it is also necessary to The connection hole on the end ring is reamed, and the docking error is easy to increase after reaming, which is poor in practicability. At the same time, the end ring will cause irreparable damage after use, and even directly affect its reuse and reusability. lower
