Technical Field

[0001] This utility model relates to the field of steel structure positioning technology, specifically a steel structure pre-assembly auxiliary device. Background Art

[0002] Pre-assembly of steel structures aims to ensure that steel structural components can be accurately and efficiently assembled before leaving the factory. This facilitates subsequent on-site construction. A foundation should be provided at the site to ensure the frame is stable, with a flat and level upper surface. Before assembly, components requiring pre-assembly can be numbered and marked for easy identification and assembly. Positioning devices can be used during assembly to assist in positioning the steel structure, facilitating welding or connections at joints.

[0003] The existing patent publication number CN211499847U discloses a pre-assembly positioning device for a steel structure space frame, which includes a base. A movable shaft is fixedly installed in the middle of the front of the base. A first connecting plate and a second connecting plate are fixedly connected to one side and the top of the movable shaft, respectively. A first clamp and a second clamp are fixedly connected to the ends of the first and second connecting plates, respectively. A fixing mechanism is fixedly connected inside the first clamp. The fixing mechanism includes a fixing spring, a fixing plate, and an adjusting rod. The fixing spring is fixedly connected to the inside of the first clamp, and one end of the fixing spring is fixedly connected to the fixing plate. The adjusting rod is threaded into the inside of the first clamp. There are eight fixing mechanisms, and the eight fixing mechanisms are arranged in groups of four.
