Description

Technical Field

[0001] The utility model relates to the technical field of building fixing devices, and more specifically to a limiting bracket for welding a steel frame for factory building expansion. Background Art

[0002] In today's society, due to the continuous advancement of science and technology, in order to meet the needs of improving life and urban development, most cities have applied rail transit to alleviate the pressure of public transportation in the city. In order to meet the use of underground light rail, tunnel segments are needed to support the inner and outer walls of the tunnel. It is well known that the segments are made of welded steel frame structures on which concrete is poured and dried. The steel frame structure is an arc shape and requires an arc-shaped support frame. Since the steel frame structure requires multiple welding points and is slightly larger in size, welders need to move back and forth many times to weld, which increases the labor intensity of workers and reduces production efficiency.

[0003] The existing patent discloses a fixing device for welding pipe segment steel structure, which relates to a fixing device. The patent authorization announcement number is CN 205166214 U. Each point on the welding arc frame can be completed without the need for the welding personnel to move. The welding arc frame is designed to be an arc shape to meet the shape requirements of the steel frame structure in the pipe segment. The rotating shaft rotates on the bearing seat, which is convenient for adjusting the needs of welding the pipe segment steel frame structure on the welding arc frame. In order to enhance the firmness and support strength of the bearing seat, a reinforcing rib is installed on the bearing seat. In order to fix the steel frame structure, a guard plate is arranged on the upper edge of the welding arc frame. For easy removal, the guard plate is tilted outward by about 100°-120°. In order to ensure the support strength, a supporting rib is used on the welding arc frame to be fixed on the rotating shaft. It can be seen from the above scheme that the beneficial effect of the utility model is that it is easy to operate and saves time and effort.

[0004] However, the two ends of the welding arc frame in the patent authorization announcement number CN 205166214 U have a certain space from the ground, so that the two ends of the welding arc frame are tilted up successively under the rotation of the rotating shaft, so that each point on the welding arc frame can be completed without the need for the welder to move. The welding arc frame is designed to be an arc shape to meet the shape requirements of the steel frame structure in the pipe segment. The rotating shaft rotates on the bearing seat to facilitate the adjustment of the welding arc frame. Since the fixing device can only fix the pipe segment steel frame, it cannot meet the use requirements for the steel pipe frame. In the process of plant construction, a steel structure composed of steel pipe frames is involved, but the steel pipes are not easy to fix during the welding process, which makes it inconvenient to weld at the joints. Therefore, we propose a limit bracket for welding the steel frame for plant expansion to solve the above-mentioned problems. Utility Model Content
