Steel connector and steel connecting structure

Abstract

The invention provides a steel connector and a steel connecting structure. The steel connector comprises a rectangular side plate, and a first side plate, a second side plate, a third side plate and a fourth side plate vertically connected with four edges of the rectangular side plate. The first side plate and the second side plate are parallel and located on one side of the rectangular side plate to form a first side groove, the third side plate and the fourth side plate are parallel and located on the other side of the rectangular side plate to form a second side groove, the first side plate is perpendicular to the third side plate, and the first side plate, the second side plate, the third side plate and the fourth side plate comprise at least one hole. The steel connector is convenient to mount in the steel structure mounting process, reliable in connection, demountable and reusable, construction quality is improved, and resources are saved effectively.

Description

technical field [0001] The invention relates to the field of fasteners, in particular to a steel connecting piece and a steel connecting structure. Background technique [0002] In the existing steel structure system of a building, the prior art connection method in which steel materials are vertically connected to each other is usually through on-site welding. However, as cold-formed thin-walled section steel, domestically, A-grade steel is mostly used for processing and production. The weldability is very poor, and the thickness of the steel plate is only 2 to 3mm. Due to the limitations of workers' technology and environment, the quality of on-site welding cannot be guaranteed. At the same time, the appearance of the welding part is extremely poor, and it needs to be repainted on site; if it is a galvanized purlin, it will also form an exposed part that is easy to corrode, and the service life is short. It is very difficult to adjust and modify the vertical or horizontal...

Problems solved by technology

However, as cold-formed thin-walled section steel, domestically, A-grade steel is mostly used for processing and production. The weldability is very poor, and the thickness of the steel plate is only 2 to 3mm. Due to the limitations of workers' technology and environment, the quality of on-site welding cannot be guaranteed. At the same time, the appearance of the welding part is extremely poor, and it needs to be repainted on site; if it is a galvanized purlin, it will also form an exposed part that is easy to corrode, and the service life is short. It is very difficult to adjust and modify the vertical or horizontal purlin position, and it needs to be cut again

Moreover, when simple houses, light houses, and factory buildings are dismantled and rebuilt in different places, or temporary houses are installed multiple times, the prototype steel cannot be reinstalled again after dismantling, resulting in a serious waste of resources.
