[0001] The utility model relates to the technical field of steel structure construction, in particular to a transition piece for steel structure construction. Background Art

[0002] Steel structure is mainly composed of steel materials and is one of the main types of building structures. During the construction of steel structure buildings, adapters are often required to connect and fix steel structure components.

[0003] The existing adapter uses an L-shaped hanger to fix two square steel pipes with bolts. This connection method only has bolts as the connection point between the square steel pipe and the connector, which has a poor connection effect. During installation, multiple bolt points need to be fixed, and reserved holes need to be opened on both sides of one end of the square steel pipe. When replacing or repairing, holes need to be opened on both sides of the square steel pipe again, which is more troublesome.

[0004] The existing patent (Announcement No.: CN218508697U) is a steel structure adapter that is easy to install for steel structure construction. This utility model ensures the overall fixing effect, effectively improves the connection effect, can significantly reduce the construction time, and is easy to recycle and use with square steel pipe construction.

[0005] In response to the above problems, existing patents have provided solutions. However, in actual steel structure construction, due to the influence of factors such as design requirements and on-site environment, the connection angles between steel structure components often need to be adjusted. However, most of the existing adapters are not convenient for adjusting the connection angles, which reduces the flexibility of the adapters. In addition, due to the inconvenience in adjusting the angles, the connections between steel structure components are not precise enough, which in turn affects the stability and safety of the steel structure. In addition, the difficulty in adjusting the angles will cause delays in the construction process, which in turn affects the progress of the entire project.

[0006] Therefore, an adapter for steel structure construction is proposed. Utility Model Content

The reinforcement component 6 can be set so that when the reinforcement component 6 is rotated, it can be rotated to make the upper connecting block 1, the lower connecting block 2 and the fine-tuning component 4 fit tightly on the steel structure component, so that the upper connecting block 1, the lower connecting block 2 and the fine-tuning component 4 provide a strong fixing force for the steel structure component through the rotation of the reinforcement component 6.

[0031] Specifically, such as Figure 4 As shown, the reinforcement component 6 includes a first "J"-shaped block 601, the inner wall of the first "J"-shaped block 601 is fixedly connected to the surface of the upper connecting block 1 and the U-shaped block 405 respectively, and the tops of both sides of the first "J"-shaped block 601 are fixedly connected with reinforcement bolts 602, which pass through the first "J"-shaped block 601 and extend to the bottom of the first "J"-shaped block 601. The surface of the reinforcement bolt 602 is provided with an auxiliary spring 603, and the top of the auxiliary spring 603 is in contact with the bottom of the first "J"-shaped block 601.

After the reinforcing bolt 602 is rotated, the second "X"-shaped block 604 can be pushed upward under the guidance of the threaded pattern on the reinforcing bolt 602, and then when the second "X"-shaped block 604 moves upward, the auxiliary spring 603 can be squeezed toward the first "X"-shaped block 601, and the two U-shaped blocks 405 are brought close to each other and the upper connecting block 1 and the lower connecting block 2 are gradually brought close to each other, and the U-shaped blocks 405 are brought close to each other and the upper connecting block 1 and the lower connecting block 2 are gradually brought close, so that the U-shaped block 405 is tightly fitted to the steel structure component and the upper connection is formed. The connecting block 1 and the lower connecting block 2 are tightly fitted with the steel structure member, and through the continuous rotation of the reinforcing nut 605, the U-shaped block 405, the upper connecting block 1 and the lower connecting block 2 provide a strong fixing force for the steel structure member. When the angle of the transferred steel structure member needs to be adjusted, the U-shaped block 405 is rotated, so that the U-shaped block 405 drives the connecting plate 402 to rotate, and then the connecting plate 402 drives the rotating rod 401 to rotate in the connecting hole 3, and when the connecting plate 402 rotates, it can drive the auxiliary bolt 403 to slide in the arc groove 5, and then after rotating to the required angle, the fastening nut 404 is rotated, and after the fastening nut 404 is in close contact with the upper connecting block 1 and the lower connecting block 2, the angle adjustment of the steel structure member is completed.
