[0002] At present, steel columns and steel beams are generally connected by end plate connection or mortise and tenon connection. The end plate connection method greatly increases the amount of structural steel, resulting in a sharp increase in costs; the mortise and tenon connection has a complex structure and requires high processing accuracy; and the above two connection methods require a large amount of on-site welding, high requirements for weld quality, and low on-site installation efficiency, which restricts the development of steel structure prefabricated buildings. In this regard, it is urgent to propose a new design for the connection between steel columns and steel beams to reduce the connection cost and improve the installation efficiency while ensuring the safety of the node structure. Summary of the invention

[0005] Furthermore, the steel column is formed by processing square steel, and rectangular holes are opened on two or four symmetrical sides, and the length and width of the rectangular holes are 5 mm larger than the length and width of the corresponding cross-section of the integrated beam support.

[0006] Furthermore, when the integrated beam support passes through the steel column from two directions, the integrated beam support includes a main beam support and a secondary beam support, the main beam support passes through the steel column horizontally, the secondary beam support passes through the steel column and the main beam support longitudinally, and the main beam support is welded to the secondary beam support.

[0007] Furthermore, the main beam support is bent or punched into a U-shape by a steel plate, and its inner hollow width is 5 mm greater than the width of the steel beam. A connecting plate is provided in the middle of the main beam support, and both ends of the connecting plate are aligned with both sides of the steel column. A hole is opened in the middle of the main beam support, and holes for passing through the secondary beam support are provided on both sides of the main beam support; the structure of the secondary beam support is the same as the main beam support except that no through holes are provided on both sides.

[0008] Furthermore, the steel column and the integrated beam support are welded on the outside of the steel column.

[0009] Furthermore, the steel column is filled with high performance concrete.

[0010] Furthermore, the steel beam is installed in the integrated beam support by hoisting.

[0011] Furthermore, the steel beam may be a lattice composite beam, a U-shaped steel beam or an I-shaped steel beam.

[0012] Furthermore, the integrated beam support is welded to the steel beam at the upper part and the side of the steel beam.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention eliminates the traditional connecting end plate and replaces it with an integrated beam support that penetrates the steel column as a whole and is then welded to the steel column. High-performance concrete is poured into the steel column to form a connecting node. The steel beam is installed in the integrated beam support by hoisting and fixed by welding. The steel column and the steel beam are connected by the integrated beam support to form a steel structure frame. This node design has the advantages of reducing the amount of structural steel used, node manufacturing is completed in the factory to ensure the quality of node construction, and there is no need to set up a positioning device when the steel beam is installed on site, which improves the installation efficiency.
