As a crucial aspect of steel structure construction, the quality of steel structure connections directly affects the safety and stability of the entire building structure.

[0003] Steel column connection construction is an integral part of steel structure construction. Existing methods require four ear plates around the steel column for positioning, then clamped together with double-clamp plates for easy positioning and welding. This process necessitates welding eight ear plates and fabricating eight clamp plates in the factory, and on-site installation requires installing and removing numerous bolts. Furthermore, after welding the steel column, eight ear plates need to be cut, making the process cumbersome, labor-intensive, costly, and time-consuming. Therefore, developing a steel structure connection device that effectively solves these problems is of significant practical importance. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] This utility model discloses a connection device for building steel structures, according to the appendix. Figure 1-2 As shown, it includes a connecting unit 1, and an auxiliary installation unit 2 is provided on the connecting unit 1;

[0039] Connection unit 1 includes:

[0040] First connecting block 11;

[0041] The second connecting block 12 has its end moving against the end of the first connecting block 11;

[0042] Sleeve 13 is fitted onto the ends of the first connecting block 11 and the second connecting block 12;

[0043] Locking bolt 14 is threaded onto sleeve block 13. The number of locking bolts 14 can be set according to the size of the steel structure to ensure the stability of the connection. Tightening the locking bolt 14 is used to fix the ends of the first connecting block 11 and the second connecting block 12.

[0044] During steel structure connection, firstly, the first connecting block 11 and the second connecting block 12 are fitted onto the top of the lower steel column, so that the bent block of the second connecting block 12 abuts against the extension block of the first connecting block 11, achieving initial connection. Then, the sleeve block 13 is fitted onto the outside of the extension block and the bent block. Through the constraint of the sleeve block 13, the first connecting block 11 and the second connecting block 12 maintain a relatively stable positional relationship. Finally, the locking bolt 14 is tightened, so that the locking bolt 14 is threadedly connected to the extension block and the bent block respectively. As the locking bolt 14 is tightened, the sleeve block 13 exerts a compressive force on the extension block and the bent block, thereby tightly fixing the first connecting block 11 and the second connecting block 12 together, completing the steel structure connection. For disassembly, simply loosen the locking bolt 14 in the opposite direction and remove the sleeve block 13 to separate the first connecting block 11 and the second connecting block 12, achieving quick disassembly.

[0045] The first connecting block 11, the second connecting block 12, the sleeve block 13, and the locking bolt 14 are used to achieve quick connection and disassembly. During construction, simply connect the first connecting block 11 and the second connecting block 12, put on the sleeve block 13, and tighten the locking bolt 14 to complete the connection; disassembly is done by reversing the operation, which is simple and convenient; moreover, the connecting device can be reused, reducing construction costs.

[0046] According to the appendix Figure 1-2 As shown, furthermore, extension blocks are fixedly connected to both ends of the first connecting block 11;

[0047] The two ends of the second connecting block 12 are fixedly connected with bending blocks, which move against the extension block.

[0048] According to the appendix Figure 1-2 As shown, further, the sleeve 13 is fitted onto the outside of the extension block and the bending block.

[0049] According to the appendix Figure 1-2As shown, the locking bolt 14 is further threadedly connected to the extension block and the bending block, respectively.

[0050] According to the appendix Figure 1-2 As shown, the auxiliary installation unit 2 further includes:

[0051] Fixing block 21 has a U-shaped design in the middle part, which facilitates welding at the connection points after the steel structure is positioned.

[0052] Positioning component 22, which is used for the initial positioning of the steel structure;

[0053] The fixing component 23 is located below the positioning component 22 and is used to fix the position of the steel structure.

[0054] According to the appendix Figure 1-2 As shown, furthermore, the fixing blocks 21 are fixedly connected to both sides of the first connecting block 11;

[0055] The fixing blocks 21 are fixedly connected to both sides of the second connecting block 12.

[0056] According to the appendix Figure 1-3 As shown, the positioning component 22 further includes:

[0057] Positioning block 221, positioning block 221 is movable and resists the steel structure;

[0058] The slide rod 222 has one end fixedly connected to the positioning block 221, and the other end slidably connected to the fixing block 21.

[0059] Spring 223 is sleeved on the outside of slide rod 222 and located between positioning block 221 and fixing block 21. During steel structure installation, the steel structure is brought close to positioning block 221, and positioning block 221 moves against the steel structure under the elastic action of spring 223. When the steel structure shifts position, positioning block 221 is compressed, causing slide rod 222 to slide on fixing block 21. Simultaneously, spring 223 is compressed, generating elastic force. This elastic force ensures that positioning block 221 maintains close contact with the steel structure, thus providing initial positioning and ensuring the accuracy of the steel structure's position during installation.

[0060] According to the appendix Figure 1-3 As shown, further, the fixing component 23 includes:

[0061] Disc 231, Disc 231 and the steel structure move together;

[0062] A fastening bolt 232 is used, with one end threadedly connected to a disc 231 and the other end threadedly connected to a fixing block 21. After the steel structure is initially positioned, the fastening bolt 232 is rotated, causing one end of the bolt 232 to move towards the disc 231. The disc 231 then comes into contact with the steel structure under the push of the fastening bolt 232. As the fastening bolt 232 is tightened, the pressure exerted by the disc 231 on the steel structure gradually increases, thus firmly fixing the steel structure in the predetermined position and preventing it from moving during subsequent connections, ensuring the accuracy and quality of the connection.
