[0033] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] Steel structure buildings generally have characteristics such as high height and large span. Due to limitations such as transportation and installation site conditions, steel components need to be processed in sections at the factory and transported to the site for installation. Especially for the roof structures of station buildings, they are usually composed of large-span steel pipe trusses. The cross-sectional specifications of the steel pipes are diverse, and the number of components installed on site is large. When docking and installing segmented members on site, to ensure construction safety, temporary connection and fixation are required before final welding and fixation. After the connection and fixation, the hoisting equipment can release the hook. Generally, the temporary connection measure for steel pipe docking and installation is to use steel code plates or steel splints in combination with temporary installation bolts for connection and fixation. However, using this connection method requires welding and fixing the steel code plates or steel splints on site, and later, the steel code plates or steel splints on the segmented rods need to be removed. The construction efficiency is relatively low, and it is difficult to ensure the specifications and welding quality of the steel code plates or steel splints, posing certain safety hazards. Moreover, the removed steel code plates or steel splints cannot be recycled, resulting in relatively large material losses.

[0035] The following will describe the embodiments of the present invention in conjunction with Figures 1 to 4 .

Through the detachable connection form, it is convenient for installation and disassembly operations, which is beneficial to improving construction efficiency, and can achieve recycling and reduce material losses.

A plurality of connecting pieces 2 are arranged at intervals along the circumferential direction of the segmented rod 1. One end of the connecting piece 2 is detachably connected to one sleeve assembly 3, and the other end is detachably connected to the other sleeve assembly 3, so that the two segmented rods 1 to be butt-jointed are temporarily fixedly connected together through the sleeve assembly 3 and the connecting piece 2, facilitating subsequent welding and fixing of the two segmented rods 1. Through the detachable connection form, compared with welding connection and the removal of subsequent welding parts, the installation or disassembly operation is more convenient, which is beneficial to improving the construction efficiency, can also achieve recycling use, reduce material loss, and can avoid the problems that the specifications and welding quality of steel code plates or steel splints in the related art are difficult to guarantee, which is beneficial to reducing potential safety hazards.

[0051] Specifically, by sequentially connecting the ends of a plurality of second arc-shaped plates 321 in series along the circumferential direction of the first annular plate 31 to form the second annular plate 32, it is convenient to sleeved the second annular plate 32 on the outer peripheral side of the first annular plate 31, which is beneficial to improving the operability.
