[0021] It is easy to understand that according to the technical scheme of the utility model, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole or as the limitation or restriction of the technical scheme of the utility model.

[0022] A prefabricated assembly type building beam column joint structure, referring to Figs. 1-3 , comprising a column 1 and two cross beams 2 horizontally arranged on the column 1, the column 1 as a vertical support member provides a solid foundation for the whole joint structure.

[0023] The top of the column 1 is sleeved with a connecting sleeve 3, and the top of the connecting sleeve 3 is provided with a T-shaped slot, which provides accurate and stable positioning for the connection of the subsequent cross beams 2.

[0024] The end of the cross beam 2 is provided in a "N" shape structure, and the ends of the two cross beams 2 are inserted into the T-shaped slot and in contact with each other, which forms a stable connection between the cross beam 2 and the connecting sleeve 3 and effectively transmits the load. The overall height of the cross beam 2 is equal to the depth of the T-shaped slot, and the upper surfaces of the two cross beams 2 and the upper surface of the connecting sleeve 3 are coplanar, which not only ensures the flat and beautiful appearance of the node, but more importantly, enables the node to uniformly distribute the load when in stress, avoiding stress concentration.

[0025] The connecting sleeve 3 is laterally movably inserted with a horizontal plate 4 perpendicular to the cross beam 2, and the horizontal plate 4 penetrates the position where the two cross beams 2 abut, which further enhances the connection integrity between the cross beams 2 and the connecting sleeve 3, prevents loosening or displacement at the node, has a positioning function, and plays a reinforcing role. When the column 1 is damaged or loses its supporting function, the overall stability of the cross beam 2 is good, and it can withstand the pressure from above to a certain extent.

[0026] Further, the two cross beams 2 and the connecting sleeve 3 are provided with slots for accommodating the horizontal plate 4, and the slots on the cross beam 2 are located below the horizontal part and at the top of the vertical part of the cross beam 2. Such slot arrangement ensures that the horizontal plate 4 can accurately penetrate the key position and play its reinforcing role, while not affecting the structural performance of the cross beam 2 itself, and can limit the compression subsidence at the abutting position of the two cross beams 2 to a certain extent.

[0027] The top of the column 1 is provided in a square prism shape, and the bottom of the connecting sleeve 3 is provided with a square slot matched with the top of the column 1. A plurality of screw rods 5 are transversely arranged at the bottom of the connecting sleeve 3 and the top of the column 1, and the two ends of the screw rod 5 are connected with nuts through threads. This connection method of the column 1 and the connecting sleeve 3 ensures the firm and reliable installation of the connecting sleeve 3 on the column 1 through the fastening action of the screw rod 5 and the nut, and can effectively resist various external forces.

[0028] The screw rod 5 is parallel to the length direction of the cross beam 2, and the adjacent screw rods 5 are arranged at equal intervals, which makes it more balanced and efficient in resisting the transverse force from the cross beam 2. Meanwhile, the equal interval arrangement facilitates construction and installation, improves work efficiency, and provides certain support for the subsidence of the cross beam 2 when subjected to vertical extrusion force. The screw rod 5 is partially or entirely located directly below the cross beam 2, making the support more targeted and effective.

[0029] The technical scope of the utility model is not only limited to the content in the above description, and the person skilled in the art can make various deformations and modifications to the above embodiment without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
