[0002] With the rapid development of the field of architecture, triangular tube trusses are often used in large stadiums due to their good structural stress characteristics. The triangular tube truss structure is a kind of space structure composed of triangular thin-walled members and triangular thin-walled plates. The plane composed of triangular thin-walled members is called a truss plane, and the node of the triangular thin-walled member is called a node. The basic introduction is a combined system composed of two or three mutually perpendicular triangular components, which has the advantages of large rigidity, good stability, and strong lateral force resistance. However, it also has the disadvantages of complex structure and difficult construction. The concept of triangular component is an independent unit that connects to form a closed geometric space, such as beams, columns, and arches. When these components form a stable and continuous frame in three-dimensional space, they form a triangular frame system (referred to as a tripod). Due to the similar stress characteristics of this structure to beams, it is also called a rigid frame. According to the different support methods, it can be divided into: no-hinge joint support tripod and hinge joint support tripod structure.

[0048] Embodiment 2

[0049] Reference Figures 1 to 7 On the basis of embodiment 1, the fixing device 2 comprises a fixing seat 21, a spherical groove 22 is formed in the side of the fixing seat 21 facing the web 3, a rotating ball 23 is rotatably connected in the spherical groove 22, a rotating rod 24 is arranged on the side of the rotating ball 23 facing the web 3, the rotating rod 24 is connected to the web 3 through a connecting block 25, and a diagonal pull rod 26 is hingedly connected to the side surface of the connecting block 25. A rotating ring 27 is hingedly connected to the end of the diagonal pull rod 26 away from the connecting block 25, and the inner wall of the rotating ring 27 is connected to the outer wall of the fixing seat 21.

[0050] The side of the fixed seat 21 away from the spherical groove 22 is fixedly connected to the side of the chord 1, and the side of the connecting block 25 away from the rotating rod 24 is fixedly connected to the side of the web rod 3.

[0052] When the truss is subjected to a large impact and shakes, relative displacement occurs between the chord members 1. At this time, the chord members 1 at both ends of the web member 3 drive the two ends of the web member 3 to move in different directions. When the web member 3 is subjected to torsion and tension, it can rotate relative to the chord members 1 at both ends through the rotating bolt and the fixing device 2, thereby buffering the impact force. The relative rotation will not damage the connection strength between the web member 3 and the chord members 1, thus protecting the connection between the web member 3 and the chord members 1 and avoiding the situation where the connection is cracked due to the impact force, reducing the connection strength. It is safer and more reliable to use. When the web member 3 rotates, the rotating ball 23 is driven to rotate through the connecting block 25 and the rotating rod 24. At the same time, the connecting block 25 drives the diagonal tie rod 26 and the rotating ring 27 to rotate. The setting of the diagonal tie rod 26 and the rotating ring 27 can improve the strength of the connection between the web member 3 and the fixing device 2, making the rotating connection more stable and reliable.
