[0002] In steel structure construction, when it is necessary to install a circular frame steel structure, the round tube needs to be divided into segments, and steel plates and stiffening plates are welded at the locations where each segment of the round tube is disconnected. However, the round tube is usually severely deformed after welding. At the same time, the round tube needs to be arched after the stiffening plate is welded. Due to the large number of joint points, the curvature of the round tube does not meet the design requirements.

[0003] As disclosed in the Chinese utility model patent with an authorization announcement date of 2020.06.02 and an authorization announcement number of CN2115602204U, a fastener for circular tubes includes: a first connecting member, including a first lower connecting portion and a first upper connecting portion; and a second connecting member, arranged parallel to and opposite to the first connecting member; the second connecting member includes a second lower connecting portion and a second upper connecting portion; wherein a first supporting cavity is formed between the second lower connecting portion and the first lower connecting portion; and a second supporting cavity is formed between the second upper connecting portion and the first upper connecting portion.

[0004] In the above prior art, two different round tubes are connected by fasteners, which is convenient for connection. However, the fasteners are stuck on the outer surface of the round tubes, and the two are prone to relative displacement under external force factors, resulting in separation of the round tubes.

[0005] Therefore, how to make the connection nodes between round tubes firm and stable is a technical problem that needs to be solved urgently. Utility Model Content
