Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a steel structure beam-column connection structure. Background Technique

[0002] Steel structure connection refers to the mutual connection between steel structure components or parts. The common steel structure connections are weld connection, bolt connection or rivet connection. Bolt connection is further divided into ordinary bolt connection and high-strength bolt connection.

[0003] The existing steel structure beam-column connection structure can refer to the Chinese utility model patent with the authorization announcement number CN214884385U, which discloses a connection structure of a steel structure beam-column. "It includes a steel column, a steel beam and a reinforcing sleeve plate fixedly arranged at the end of the steel beam. The reinforcing sleeve plate has a U-shaped groove that matches the shape of the side wall of the steel column. When connecting, the U-shaped groove on the reinforcing sleeve plate is clamped on the side wall of the steel column so that the reinforcing sleeve plate hugs the outer side wall of the steel column. Fasteners are also used to connect between the reinforcing sleeve plate and the steel column."

[0004] When the above device is in use, the existing device uses bolts for positioning and fixing. There are few holes opened on the column section, and the influence on the bearing capacity of the column is small. The reinforcing sleeve plate plays a strengthening role for the joint and the column section. Compared with the outer reinforcing ring or the reinforcing plate joint, it is more conducive to realizing the design concepts of "strong column and weak beam, strong joint and weak structure" and "plastic hinge outward movement". The existing device uses bolts for positioning, and this placement has the problem of difficult positioning. Moreover, the hoisting machinery needs to hoist the crossbeam device for a long time for positioning and connecting work. And under the condition of maintaining the original design concept, the welding and multi-point threaded connection methods are used to avoid the problem of unstable connection of the crossbeam. Therefore, a steel structure beam-column connection structure that solves the above problems is needed. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a steel structure beam-column connection structure, which has the advantages of guiding positioning and multi-point threaded connection, and solves the problems raised in the above background technique.

[0006] The utility model provides the following technical solution: A steel structure beam-column connection structure includes a steel column. A prefabricated connector is sleeved on the outer wall of the steel column. A long threaded hole is opened on the outer wall of the steel column. A long screw is threadedly connected to the inner wall of the long threaded hole. A flat plate is arranged on the outer wall of the prefabricated connector. A support plate is fixedly connected to the bottom of the flat plate. A welding strip is arranged on the outer wall of the flat plate. A crossbeam is lapped on the inner wall of the prefabricated connector. A connection screw hole is opened on the outer wall of the crossbeam. An introduction groove is arranged on the outer wall of the prefabricated connector. A short screw is threadedly connected to the inner wall of the connection screw hole. A side beam is lapped on the inner wall of the prefabricated connector. A side support plate is connected to the outer wall of the prefabricated connector.

[0007] As a preferred technical solution of the present utility model, the long threaded holes are opened on the outer walls of the prefabricated connecting piece and the steel column, and the long threaded holes penetrate through the outer wall of the steel column to the other side.

[0008] As a preferred technical solution of the present utility model, the shape of the support plate is triangular, and the welding strips are arranged between the flat plate, the support plate and the prefabricated connecting piece.

[0009] As a preferred technical solution of the present utility model, the connecting screw holes are opened on the outer walls of the flat plate and the cross beam, and the connecting screw holes penetrate through the outer walls of the flat plate and the cross beam.

[0010] As a preferred technical solution of the present utility model, the number of the guiding grooves is several, and several guiding grooves are symmetrically arranged on the top of the prefabricated connecting piece.

[0011] As a preferred technical solution of the present utility model, the number of the short screws is four, and the cross beam and the flat plate are connected by two pairs of symmetric short screws.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. For this steel structure beam-column connection structure, through the mutual cooperation of the guiding grooves, the prefabricated connecting piece, the side beam and the cross beam on the device, the outer walls of the side beam and the cross beam on the device are made to be the same size as the inner wall of the prefabricated connecting piece. When the cross beam and the side beam need to be placed in the inner wall of the prefabricated connecting piece, the cross beam and the side beam are placed in the inner wall of the prefabricated connecting piece from top to bottom. Thus, when the outer walls of the cross beam and the side beam collide with the arc-shaped walls of the guiding grooves, the guiding grooves are used to guide the cross beam and the side beam into the inner cavity of the prefabricated connecting piece, thereby making the lapping work smoother.

[0014] 2. For this steel structure beam-column connection structure, through the mutual cooperation of the flat plate, the support plate, the welding strips, the side support plate, the cross beam and the side beam on the device, when the cross beam on the device is placed on the top of the flat plate, the contact points between the flat plate, the support plate and the prefabricated connecting piece are first welded by the welding strips, and the cross beam is stably placed on the top of the flat plate, and firm threaded connection is carried out by the short screws. Thus, when the four symmetric short screws on the device can be stably connected, it can be reflected whether the cross beam is stably placed on the outer wall of the flat plate. The side beam on the device is installed in the same way when placed on the side support plate, avoiding the problem of unstable connection between the side beam and the cross beam.

[0022] Please refer to Figures 1-5 , a steel structure beam-column connection structure, including a steel column 1, a prefabricated connecting piece 2 is sleeved on the outer wall of the steel column 1, a long threaded hole 3 is opened on the outer wall of the steel column 1, a long screw 4 is threadedly connected to the inner wall of the long threaded hole 3, a flat plate 5 is provided on the outer wall of the prefabricated connecting piece 2, a support plate 6 is fixedly connected to the bottom of the flat plate 5, a welding strip 7 is provided on the outer wall of the flat plate 5, a cross beam 8 is lapped on the inner wall of the prefabricated connecting piece 2, a connecting screw hole 9 is opened on the outer wall of the cross beam 8, a guiding groove 10 is provided on the outer wall of the prefabricated connecting piece 2, a short screw 11 is threadedly connected to the inner wall of the connecting screw hole 9, a side beam 12 is lapped on the inner wall of the prefabricated connecting piece 2, a side support plate 13 is connected to the outer wall of the prefabricated connecting piece 2. Since the side support plate 13 on the device has the same structure as the flat plate 5 and the support plate 6, the side support plate 13 on the device is also connected to the prefabricated connecting piece 2 using the welding strip 7, and the shape and size of the side support plate 13 are slightly smaller than those of the flat plate 5 and the support plate 6, so that the side support plate 13 on the device is welded on both sides of the steel column 1.

[0023] In a preferred embodiment, the long threaded hole 3 is formed in the outer walls of the prefabricated connector 2 and the steel column 1, and the long threaded hole 3 penetrates through the outer wall of the steel column 1 to reach the other side. By forming the long threaded hole 3 in the outer walls of the prefabricated connector 2 and the steel column 1 on the device, the long threaded hole 3 on the device first passes through the outer wall of the prefabricated connector 2 and then through the outer wall of the steel column 1, so that the long screw 4 on the device can fix and connect the prefabricated connector 2 to the outer wall of the steel column 1 in the inner cavity of the long threaded hole 3.

[0024] In a preferred embodiment, the shape of the support plate 6 is triangular, and the welding strip 7 is arranged between the flat plate 5, the support plate 6 and the prefabricated connector 2. By the triangular shape of the support plate 6 on the device, the support plate 6 on the device plays a triangular support role at the bottom of the flat plate 5, and the support plate 6 on the device is first welded to the flat plate 5, and then the support plate 6 and the flat plate 5 are welded to the outer wall of the prefabricated connector 2 by using the welding strip 7.

[0025] In a preferred embodiment, the connecting screw hole 9 is formed in the outer walls of the flat plate 5 and the cross beam 8, and the connecting screw hole 9 penetrates through the outer walls of the flat plate 5 and the cross beam 8. By forming the connecting screw hole 9 in the outer walls of the flat plate 5 and the cross beam 8 on the device, the connecting screw hole 9 on the device first passes through the outer wall of the flat plate 5 and then through the outer wall of the cross beam 8, so that the connecting screw hole 9 on the device is formed in the outer walls of the flat plate 5 and the cross beam 8 at the same time and provides a connection point for the short screw 11.

[0026] In a preferred embodiment, the number of the guiding grooves 10 is several, and several guiding grooves 10 are symmetrically arranged at the top of the prefabricated connector 2. By the several guiding grooves 10 on the device, when the cross beam 8 and the side beam 12 on the device are put in place, the guiding grooves 10 symmetrically formed in the inner wall of the prefabricated connector 2 are used for guiding. Thus, when the cross beam 8 and the side beam 12 are placed from top to bottom, they are guided into the inner wall of the prefabricated connector 2 by the arc-shaped guiding grooves 10.

[0027] In a preferred embodiment, the number of the short screws 11 is four, and the four short screws 11 connect the cross beam 8 and the flat plate 5 in a pairwise symmetric manner. By the four short screws 11 on the device, when the cross beam 8 on the device is placed on the inner wall of the prefabricated connector 2 and at the top of the flat plate 5, the four short screws 11 are used for threading connection work on both sides of the cross beam 8. Thus, when the short screws 11 on the device perform the threading connection, the cross beam 8 must be placed stably on the top of the flat plate 5 first, and then the flat plate 5 and the cross beam 8 can be firmly connected by the short screws 11 through threading.

[0028] Working principle: First, through the mutual cooperation of the inlet groove 10, prefabricated connecting piece 2, side beam 12, and cross beam 8 on the device, the outer walls of the side beam 12 and cross beam 8 on the device are made to be the same size as the inner wall of the prefabricated connecting piece 2. When the cross beam 8 and side beam 12 need to be placed in the inner wall of the prefabricated connecting piece 2, the cross beam 8 and side beam 12 are placed from top to bottom in the inner wall of the prefabricated connecting piece 2. Thus, when the outer walls of the cross beam 8 and side beam 12 collide with the arc wall of the inlet groove 10, the inlet groove 10 is used to guide the cross beam 8 and side beam 12 into the inner cavity of the prefabricated connecting piece 2, making the lapping work smoother. Then, through the mutual cooperation of the flat plate 5, support plate 6, welding strip 7, side support plate 13, cross beam 8, and side beam 12 on the device, when the cross beam 8 on the device is placed on the top of the flat plate 5, the contact points of the flat plate 5 and support plate 6 with the prefabricated connecting piece 2 are first welded using the welding strip 7, and the cross beam 8 is stably placed on the top of the flat plate 5 and firmly connected by screw threads using the short screw 11. Thus, when the four symmetric short screws 11 can be stably connected, it can be reflected whether the cross beam 8 is stably placed on the outer wall of the flat plate 5. The side beam 12 on the device is installed on the side support plate 13 using the same method to avoid the problem of unstable connection between the side beam 12 and cross beam 8.
