[0002] In existing technologies, the connection structures at the ends of trusses are generally fixed, which cannot cope with some special working conditions. For example, when connecting an arc truss that requires the hanging of a membrane structure, the fixed structure has the problem that hanging the membrane is cumbersome. The membrane needs to be stretched close to the two sides of the truss, which consumes a lot of manpower. It also cannot adapt to trusses of different sizes or angles, making construction cumbersome, inefficient, and poorly applicable. Utility Model Content

A support rod is connected between the side connecting plates. A rotating shaft is connected between the two connecting plates. The edges of the two rotating plates are provided with grippers that are rotatably connected to the rotating shaft through sleeves. The grippers on the edges of the two rotating plates are staggered. The outer side of the rotating plate is connected to the connecting plate. The connecting plate has a clearance groove corresponding to the position of the gripper. The connecting plate is connected to the end tube of the adjacent arc-shaped truss component. One end of the rotating shaft extends to the outer side of one of the columns and is provided with a slot. The locking block is engaged in the slot and can be detachably fixed to the outer side of the column. When installing the curved truss assembly, the two curved truss assemblies are connected to the rotating plate through the connecting plate, and can rotate around the rotating axis to adjust the angle and distance between the two curved truss assemblies, as well as the height of the curved truss assembly from the ground, to facilitate the hanging of the diaphragm. After rotating to the desired position, a support structure can be set between the rotating plates to fix the angle, and the support structure can be removed when disassembling or adjusting the angle.

[0005] Preferably, the base is connected to four corner fixing plates, which are fixed to the ground by rivets.

[0006] Preferably, diagonal braces connect the two sides of the column to the base, and an auxiliary support rod connects the middle of the diagonal braces to the column. This is used to improve the overall structural stability.

[0007] Preferably, the connection between the connecting plate and the end tube of the arc-shaped truss assembly is provided with reinforcing ribs supporting the side of the tube. This improves the support of the connecting plate and the arc-shaped truss assembly.
