Description

Technical Field

[0001] The utility model relates to the technical field of steel structure joint instruments, and particularly relates to a steel structure assembly joint. Background Art

[0002] The steel structure assembly joint is an intermediate part connecting beam-column joints, including a central sleeve and side sleeves, and is usually spliced by means of bolt locking. During the assembly stage, the side sleeves are often manually aligned according to the positions of cross beams at various places, and then holes are drilled on the columns on site. Since the side sleeves around the central sleeve need to maintain the same height to balance the heights of each cross beam, however, manual alignment causes a certain degree of height error between the side sleeves, which easily leads to the deviation of the installation position of the cross beam and is difficult to keep flush; and the existing steel structure assembly joints are only fixed by screws and welding, and the connection structure has poor stability. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a steel structure assembly joint for the deficiencies of the prior art to solve the problems raised in the background art.

[0004] To achieve this purpose, the utility model adopts the following technical solutions:

[0005] A steel structure assembly joint includes a centrally placed central sleeve. A left-right connecting plate is connected to each of the left and right end faces of the central sleeve, and a front-back connecting plate is connected to each of the front and back end faces of the central sleeve. Among them, a convex strip is fixed to each of the front and back surfaces of the left-right connecting plate, and a slot is formed on each of the left and right surfaces of the front-back connecting plate, and the convex strip and the slot are coupled and inserted; a side sleeve is welded to each side of the left-right connecting plate and the front-back connecting plate away from the central sleeve.

[0006] Four horizontally arranged transverse screws penetrate through the left and right sides of the central sleeve, and four longitudinally arranged longitudinal screws penetrate through the front and back sides of the central sleeve; and the outer ends of the transverse screws outside the central sleeve penetrate out from the four corners of the left-right connecting plate respectively, and the outer ends of the longitudinal screws outside the central sleeve penetrate out from the four corners of the front-back connecting plate respectively.

[0007] As a preferred solution of the steel structure assembly joint, the transverse screws are all located between the longitudinal screws, and the outer surface of the transverse screw is not in contact with the outer surface of the longitudinal screw.

[0008] As a preferred solution of the steel structure assembly joint, through holes for the transverse screws and longitudinal screws to penetrate are respectively formed on the front-back sides and left-right sides of the central sleeve.

[0009] As a preferred solution for the steel structure assembly joint, nuts are locked at the positions of the transverse screw and the longitudinal screw outside the central sleeve, and gaskets are provided on the end faces of the nuts close to the outer surfaces of the left and right side connecting plates and the front and rear side connecting plates.

[0010] As a preferred solution for the steel structure assembly joint, a side plate is fixed on each of the front and rear surfaces of the left and right side connecting plates and the left and right surfaces of the front and rear side connecting plates, and the side plates are in contact and coupled with each other to form a square bar.

[0011] As a preferred solution for the steel structure assembly joint, the length of the convex strip is 1 / 2 of the length of the side plate, and the depth of the slot is 1 / 2 of the length of the side plate.

[0012] As a preferred solution for the steel structure assembly joint, round holes for the transverse screw and the longitudinal screw to penetrate are respectively provided at the four inner corners of the left and right side connecting plates and the front and rear side connecting plates, and the round holes inside the left and right side connecting plates and the front and rear side connecting plates are arranged in an up-and-down staggered manner.

[0013] As a preferred solution for the steel structure assembly joint, triangular support plates are welded on the upper and lower surfaces of the side sleeve, and the mutually converging and approaching surfaces of the triangular support plates are fixedly connected to the outer surfaces of the left and right side connecting plates and the front and rear side connecting plates.

[0014] As a preferred solution for the steel structure assembly joint, the central sleeve is made of, including but not limited to, a square pipe or a round pipe, and the side sleeve is made of, including but not limited to, a square pipe or a round pipe; moreover, when the central sleeve is a round pipe, the surfaces of the left and right side connecting plates and the front and rear side connecting plates close to the central sleeve have curved arc surfaces, and the curved arc surfaces are attached to the outer surface of the central sleeve.

[0015] Advantages of the present utility model:

[0016] In the present utility model, convex strips and slots that can be mutually coupled and inserted are respectively arranged on both sides of the left and right side connecting plates and the front and rear side connecting plates of the central sleeve. Before the side sleeve is connected to the central sleeve, the pre-positioning effect of the two connecting plates is achieved by the insertion of the convex strips and the slots during the installation process, so as to ensure that the heights of the side sleeves are consistent; moreover, after the connecting plates around the column are locked by the transverse screw and the longitudinal screw, the convex strips and the slots form an integral body for the surrounding connecting plates, increasing the force conduction area of the side sleeve and making the connection of the steel structure more stable.
