1. The device of the present utility model connects the H-shaped steel column and the H-shaped steel beam through high-strength bolts. The beam-column structural components are all mechanically designed and produced in factories. The components are relatively precise and accurate, and there is almost no processing error. The site only needs to hoist and tighten the bolts. It can complete the work, reduce the workload of workers, improve the quality and work efficiency of the project, shorten the construction period and save costs.

2. The structure is simple, meets the needs of the project, significantly reduces the workload and working environment of the construction site workers, and improves the quality of the construction project, with high work efficiency and no harm. If the building meets the service period and needs to be dismantled, the structure can be dismantled. Orderly dismantling, all components can be recycled or reused, or with the increase of time, some components can not meet the normal use requirements, components can be quickly replaced, reducing maintenance costs during the service period.

3. Both ends of the H-shaped steel beam of the present utility model are composed of steel end plates with bolt holes at the ends of the H-shaped steel beams, oblique supports at the bottom and stiffeners at the corresponding positions of the webs, which increases the connection strength of the nodes and greatly increases the connection strength of the joints. The long-span distance between the vertical and horizontal steel columns is increased, which is beneficial to the needs of modern long-span buildings, and at the same time meets the requirements for engineering quality, working environment, construction period, labor volume, construction cost, etc., as well as the applicability and safety of structural use and stability.
