DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6, A prefabricated steel structure beam-column outer sleeve rigid connection node, including a clamping component, an adjusting component, a fixing plate 5 and a moving plate 6. The adjusting component includes a sliding frame 1, a first handle 2, a threaded rod 3 and a slider 4. The sliding frame 1 is arranged on the back side of the fixing plate 5, and the slider 4 slidably connected to the sliding frame 1 is arranged on the back side of the moving plate 6. The threaded rod 3 is also arranged in the sliding frame 1, and the threaded rod 3 is slidably connected to the slider 4. The clamping components are arranged on the front sides of the moving plate 6 and the fixing plate 5. The clamping component includes a support frame 7, a left and right hand threaded screw 8, a second handle 9, a moving block 10 and an L-shaped clamping plate 11. Support frames 7 are arranged on the front sides of the fixing plate 5 and the moving plate 6. The left and right hand threaded screw 8 and two groups of symmetrically arranged moving blocks 10 are arranged in the support frame 7. The left and right hand threaded screw 8 is threadedly connected to the moving block 10. The clamping plate 11 is arranged on the front side of the moving block 10. The left and right hand threaded screw 8 penetrates through the support frame 7 and is connected to the second handle 9.

[0026] Through the coordinated action of components such as the support frame 7, the left and right hand threaded screw 8, the moving block 10 and the clamping plate 11, the clamping component can achieve stable clamping of the steel structure beam. If two groups of steel structure beams are horizontally butted, after the steel structure beam is fixed to the corresponding clamping component, the first handle 2 drives the threaded rod 3 to rotate, and the slider 4 drives the moving plate 6 to move to ensure stable butt joint of the two groups of steel structure beams in the horizontal direction. If the side position of the steel structure beam needs to be expanded, first, the clamping component of the fixing plate 5 is stably fixed to the steel structure beam, and then the first handle 2 drives the threaded rod 3 to rotate to adjust the distance between the corresponding clamping plates 11 on the moving plate 6 and the fixing plate 5 up and down, ensuring stable clamping and positioning of the side expansion structure for subsequent bolt fixed connection. This structure is detachably connected to the steel structure beam, convenient for disassembly and assembly, and has wide applicability.

[0027] During actual use, a buffer pad 12 is also arranged on one side of the clamping plate 11 close to the center of the left and right hand threaded screw 8. During the clamping process, it can not only increase the friction between the clamping plate 11 and the steel structure beam to prevent the steel structure beam from sliding under the action of external forces, but also play a buffering role to avoid damage to the surface of the steel structure beam caused by rigid contact, effectively ensuring stable clamping of the steel structure beam.

[0028] During actual use, a number of positioning teeth 13 are arranged at the adjacent positions of the corresponding two groups of support frames 7 of the clamping plate 11, providing an intuitive visual positioning reference for the side expansion structure. During the side expansion support operation, the operator can quickly and accurately determine the relative position relationship between the side expansion structure, the clamping component and the steel structure beam by observing the position of the positioning teeth 13, facilitating subsequent installation and connection operations, making up for the deficiency that the existing steel structure beam is not convenient for side expansion support, reducing the operation difficulty, and improving the working efficiency of side expansion support.

[0029] In this embodiment, the first handle 2 is L-shaped, and a friction pad 14 is further provided at one end of the first handle 2 away from the sliding frame 1. By rotating the first handle 2 with the friction pad 14, the threaded rod 3 can be stably driven to rotate.

[0030] During actual use, two sets of second handles 9 are symmetrically arranged on the periphery of the support frame 7. A friction groove 15 is further provided on the second handle 9, which provides more operation stations, and the friction groove 15 ensures stable driving of the second handle 9.

[0031] During actual use, a plurality of groups of evenly arranged scale grooves 16 are further provided on the back side of the sliding frame 1, so as to visually understand the feed pitch of the slider 4, and further understand the pitch between the positioning teeth 13 in the upper and lower two directions.
