Description

Technical Field

[0001] This utility model relates to the field of building beam and column equipment, specifically a seismic-resistant building beam and column connection structure. Background Technology

[0002] Building beams and columns are the core area of ​​a building's load-bearing structure. The weight of the entire floor is concentrated on the beams and columns, so the stability of the beam-column connection is crucial. Currently, the reinforcement scheme for beams and columns is to improve the shear bearing capacity of the beam-column joint in the spatial frame by reinforcing the outer beam and column ends of the beam-column joint. In prefabricated steel structure buildings, since the beams and columns all use steel frames as support units, the beam-column connection joint lacks seismic resistance. When subjected to vibration, the connection is prone to stress concentration and breakage.

[0003] According to patent document CN113216680B, a vibration damping and reinforcement device for the connection between a building beam and column includes a column and a beam frame. The device further includes a connecting base, one end of which is fixedly mounted to the outer wall of the column, and the other end facing the beam frame, for assembling and connecting the beam frame. A limiting cavity is disposed on the side of the connecting base facing the beam frame and is clearance-fitted with the beam frame to limit the range of motion of the beam frame at the connection. In use, this technical solution, through the limiting cavity and linkage mechanism between the column and beam frame, can maintain the structural stability of the beam and column while allowing a gap at the connection. When external vibrations occur, this improves the overall seismic resistance of the beam and column and reduces the possibility of stress cracking at the connection. However, while this solution reduces cracking at the connection, it cannot provide multi-directional support and fixation at the connection, which is inconvenient in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a seismic-resistant beam-column connection structure for buildings, thereby solving the problems mentioned in the background. This utility model has a novel structure. In use, the limiting plate and the limiting groove cooperate to achieve upper and lower limiting support. The triangular limiting plate contacts the limiting groove to increase its bearing capacity. The limiting bolts achieve secondary limiting and left and right fixation of the support base and the I-beam.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant building beam-column connection structure, comprising a column, a fixed seat movably mounted on the column, a fixed plate welded to the fixed seat, the fixed plate being mounted on the column by fixed bolts, a fixed disc fixed on the fixed seat, a fixed tube fixed on the fixed disc, a threaded tube rotatably mounted at one end of the fixed tube, a threaded column rotatably mounted inside the threaded tube, a connecting lug welded to one end of the threaded column, fixed lugs movably mounted between the connecting lugs, and a support seat welded to the fixed seat.

[0006] Furthermore, an I-beam is movably installed inside the support base, and a support plate is welded inside the support base, with the support plate movably installed between the I-beams.

[0007] Furthermore, limit bolts are fixedly installed between the support plate, the I-beam, and the support base, and a fixing frame is movably installed on the I-beam.

[0008] Furthermore, a support block is welded onto the fixed frame, and a rotating seat is movably installed between the support blocks, with the rotating seat fixed to one end of the fixed lug.

[0009] Furthermore, a limiting block is welded onto the fixed frame, the limiting block is movably installed between the I-beams, and the rotating seat is installed on the support block via a rotating column.

[0010] Furthermore, a rotating seat is welded to the bottom of the fixed lug, and a swing seat is welded to the bottom of the rotating seat. The swing seat moves to contact the top of the I-beam.

[0011] Furthermore, a limiting plate is fixed inside the support base, and a limiting groove is opened at one end of the I-beam, with the limiting groove being movably mounted on the limiting plate.

[0012] Furthermore, one end of the threaded tube is mounted inside the fixed tube via a bearing seat, and the threaded column is movably mounted inside the fixed tube.

[0013] The beneficial effects of this utility model are:

[0014] In this utility model, the limiting plate and the limiting groove cooperate to achieve upper and lower limiting support during use. The triangular limiting plate contacts the limiting groove to increase its bearing capacity. The limiting bolts realize the secondary limiting and left and right fixation of the support base and the I-beam.

[0015] In this invention, the threaded column and the fixed frame cooperate to provide support for the I-beam. While providing support, the threaded column drives the rotating seat to rotate and tilt. As the rotating seat tilts, the swing seat tilts to press the I-beam, thereby achieving compression and fixation between the fixed frame and the I-beam.

[0016] This utility model provides multi-point support for the I-beam through a support base, a limiting plate, and a fixing frame, while simultaneously reinforcing it. By reinforcing the connection points, it effectively prevents breakage caused by vibration and ensures the stability of the connection points. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5This utility model provides a technical solution: a seismic-resistant building beam-column connection structure, including a column 1, a fixed seat 2 movably mounted on the column 1, a fixed plate 3 welded to the fixed seat 2, the fixed plate 3 being mounted on the column 1 by fixed bolts 4, a fixed plate 5 fixed on the fixed seat 2, a fixed pipe 6 fixed on the fixed plate 5, a threaded pipe 7 rotatably mounted on one end of the fixed pipe 6, a threaded column 8 rotatably mounted inside the threaded pipe 7, a connecting lug 9 welded to one end of the threaded column 8, a fixed lug 10 movably mounted between the connecting lugs 9, a support seat 15 welded to the fixed seat 2, an I-beam 14 movably mounted inside the support seat 15, a support plate 17 welded inside the support seat 15, the support plate 17 movably mounted between the I-beams 14, the support plate 17 being snapped onto the I-beams 14, and the support plate 17 and the support seat 15 cooperating to provide double-point limiting support for the I-beams 14.

[0025] In this embodiment, a limiting bolt 16 is fixedly installed between the support plate 17, the I-beam 14, and the support base 15. A fixing frame 12 is movably installed on the I-beam 14, and a support block is welded onto the fixing frame 12. A rotating seat 11 is movably installed between the support blocks. The rotating seat 11 is fixed to one end of the fixing lug 10. A limiting block is welded onto the fixing frame 12. The limiting block is movably installed between the I-beams 14. The rotating seat 11 is installed on the support block through a rotating column. After the fixing frame 12 is slidably installed on the I-beam 14, it cooperates with the support base 15 to provide three-point tensile support for the I-beam 14 at different positions.

[0026] In this embodiment, a rotating seat 11 is welded to the bottom of the fixed hanging ear 10, and a swing seat 13 is welded to the bottom of the rotating seat 11. The swing seat 13 is movably in contact with the top of the I-beam 14. A limiting plate 18 is fixed inside the support seat 15. A limiting groove 19 is opened at one end of the I-beam 14. The limiting groove 19 is movably installed on the limiting plate 18. One end of the threaded tube 7 is installed inside the fixed tube 6 through a bearing seat. The threaded column 8 is movably installed inside the fixed tube 6. When the threaded tube 7 rotates, the threaded column 8 rotates and moves. The rotational displacement of the threaded column 8 causes the rotating seat 11 to tilt. When the rotating seat 11 tilts, the swing seat 13 completes the compression and fixation of the I-beam 14.

[0027] In use, the device slides the fixing base 1 onto the column 1. The fixing plate 3 and fixing base 2 are then fixed in place using fixing bolts 4 according to the height of the installation point. After the fixing base 2 is fixed onto the column 1, the I-beam 14 is installed. Before installation, one end of the I-beam 14 slides through the fixing frame 12. After passing through the fixing frame 12, one end of the I-beam 14 is installed inside the support base 15. After the I-beam 14 is installed inside the support base 15, the limiting bolts 16 are installed on the support base 15 via the support plate 17 and the I-beam 14, providing initial positioning and fixing for the I-beam 14. The rear limiting plate 18 and the limiting groove 19 installed inside the support base 15 contact each other to achieve secondary limiting support. The triangular limiting plate 18 and the limiting groove 19 cooperate to effectively increase the load-bearing capacity between them and effectively reduce deformation and displacement. By rotating the threaded tube 7, the rotation of the threaded tube 7 drives one end of the threaded column 8 to move into the fixed tube 6. When the threaded column 8 moves, the connecting lug 9 drives the fixed lug 10 to move. The fixed lug 10 drives the rotating seat 11 to tilt under the movement. The tilting of the rotating seat 11 drives the swing seat 13 to tilt and press and fix the top of the I-beam 14, thereby completing the pressing and fixing according to the thickness of the I-beam 14.
