[0002] With the development of my country's economy and the enhancement of its comprehensive strength, steel structure buildings have developed rapidly. Steel structures have a series of advantages such as high strength, light weight, good seismic performance, fast construction speed, low foundation cost, small footprint, high degree of industrialization, and beautiful appearance. In steel structures, the beam-column joints have a significant impact on structural force transmission, project cost, and construction difficulty.

[0003] Based on the above, during the installation of existing steel structure beam-column joints, it is difficult to quickly and accurately align the beams and columns. Workers need to spend a lot of time and energy making repeated adjustments, which seriously affects the construction progress. Moreover, due to the inaccurate alignment of the joints, bolt holes are often misaligned, which makes it impossible to install the bolts accurately, increasing the construction difficulty and reducing the convenience of construction. Utility Model Content

This structure solves the problem of difficulty in quickly and accurately aligning beams and columns during the installation of existing steel structure beam-column nodes, which leads to inaccurate bolt installation. By setting up a positioning structure, precise and rapid alignment of beams and columns is achieved. This not only significantly reduces the difficulty of alignment for workers but also facilitates bolt tightening, preventing inaccurate bolt installation due to misalignment and significantly improving construction convenience. Furthermore, the dual constraint mechanism of the positioning frame and bolts further enhances the shear bearing capacity of the node, effectively strengthening the overall stability of the steel structure and providing reliable protection for building safety.

[0048] Connecting corner bracket 202: Located on the other side of the fixed column 1, a second insert 2021 is fixedly connected to the middle of the side wall of the connecting corner bracket 202. The second insert 2021 is also inserted into the slot 101. A second protruding plate 2022 is fixedly connected to the side of the connecting corner bracket 202 near the connecting recess 201. A second through hole 2023 is provided on the second protruding plate 2022.

[0049] Connecting bolt 203: installed in the first through hole 2013 and the second through hole 2023, and a connecting nut 2031 is engaged on the outside of the connecting bolt 203;

[0050] Positioning corner frame 204: Fixedly connected to the four corners of the connecting corner bracket 202.

[0051] A crossbeam 3 is provided on one side of the fixed column 1. The crossbeam 3 has an assembly slot 301, and a support structure 5 is installed on the bottom of the crossbeam 3 and the fixed column 1.

[0052] A connecting protrusion 302 is fixedly connected to the side of the fixed column 1 near the crossbeam 3. The connecting protrusion 302 has a connecting hole 3021, which is aligned with the assembly slot 301.

[0053] An assembly bolt 303 is installed in the connecting hole 3021 and the assembly slot hole 301, and an assembly nut 3031 is engaged on the outer side of the assembly bolt 303.

[0054] By engaging the connecting recess 201 and the connecting corner bracket 202 in the slot 101, and then fixing them to the fixed column 1 with the connecting bolt 203 and the connecting nut 2031, the alignment of the crossbeam 3 and the fixed column 1 is completed by inserting the four sides of the crossbeam 3 into the positioning corner frame 204. Then, the connecting hole 3021 is aligned with the assembly slot hole 301, the assembly bolt 303 is inserted, and finally the assembly is completed with the assembly nut 3031.

[0055] Example 2: Based on Example 1, wherein, as Figure 5 As shown, the connecting convex plate 302 is provided with a reinforcing structure 4. The reinforcing structure 4 includes a rotating bracket 401, a threaded hole 4011 and a guide groove 4012. The rotating bracket 401 is fixedly connected to the connecting convex plate 302.

[0057] By rotating the throttle 4021, the screw 402 is driven to rotate. The screw 402 engages and moves in the threaded hole 4011, thereby pushing the positioning block 403 to move. The guide rib 4031 limits and guides the positioning block 403 in the guide groove 4012, so that the positioning block 403 is accurately locked on the outside of the assembly nut 3031, which further limits and reinforces the bolts between the nodes, prevents the bolts from loosening due to vibration, and improves the stability of the beam-column node connection.

[0058] The specific usage and function of this embodiment are as follows:

[0059] In this invention, the connecting bracket 201 and the connecting angle bracket 202 are first secured in the slot 101, and then fixed to the fixed column 1 by connecting bolts 203 and connecting nuts 2031. At this point, the four sides of the crossbeam 3 are inserted into the positioning angle frame 204 to align the crossbeam 3 with the fixed column 1. Then, the connecting hole 3021 is aligned with the assembly slot 301, and the assembly bolts 303 are inserted. Finally, the assembly is completed using the assembly nuts 3031. This significantly reduces the difficulty of alignment for workers, makes it easier for workers to tighten the bolts, avoids inaccurate bolt installation due to misalignment, and significantly improves construction efficiency. The dual constraint mechanism of the positioning corner frame 204 and the bolts further improves the shear bearing capacity of the node, effectively enhances the overall stability of the steel structure, and provides a reliable guarantee for building safety. Then, by rotating the handle 4021, the screw 402 is driven to rotate. The screw 402 engages and moves in the threaded hole 4011, thereby pushing the positioning block 403 to move. Through the guide convex strip 4031, the positioning block 403 is limited and guided in the guide groove 4012, so that the positioning block 403 is accurately locked on the outside of the assembly nut 3031, which further limits and reinforces the bolts between the nodes, prevents the bolts from loosening due to vibration, and improves the stability of the beam-column node connection.
