The circulating type *-shaped tension brace tool comprises a connecting fixing ring, a through hole is formed in the side wall of the connecting fixing ring, a steel bar extends from the inner side of the through hole, the other end of the steel bar is fixedly connected with a fixing plate, and the fixing plate is fixedly connected with the connecting fixing ring. A threaded head is arranged at the end, away from the fixing plate, of the steel bar, and a clamping groove is formed in the inner side of the fixing plate. By combining the structures such as the connecting fixing rings, the steel plates, the fixing plates and the nuts, the device can be suitable for tower flanges of different specifications, the size can be adjusted, only 2-3 sets need to be manufactured for one project, materials and cost are saved, the tension brace strength can be adjusted, the control effect on the ovality deformation of the flanges is good, the flanges are prevented from being corrected, and the tower mounting efficiency is improved. Time is saved, the overall structure is light, the installation difficulty is low, installation can be completed by a single person, labor input is reduced, manpower is saved, the overall welding amount is reduced, and environmental protection, detachability and convenience in recycling are achieved.

The invention relates to the field of building construction, in particular to a space truss supporting system which comprises space truss supporting structures arranged between surrounding purlins, and each space truss supporting structure is provided with a space truss structure, adjusting pieces at the two ends and a prestress device connected with the adjusting pieces. The space truss structure is composed of a plurality of space truss standard units which are sequentially connected, each unit comprises a node, a steel support standard section, a transverse stabilizer bar, an oblique stabilizer bar and the like, and at least one layer of rectangular pyramid connecting rod structure is composed of the transverse stabilizer bar and the oblique stabilizer bar. The adjusting piece is formed by connecting an L-shaped hanging arm and an adjusting head, and the prestress device and the node can be adjustably connected. Compared with the prior art, the space truss system is constructed, the calculated length of the steel support is reduced, the horizontal and vertical stability is improved, self-weight internal force deformation is reduced, free combination can be achieved to adapt to various foundation pits, universal joints of nodes are high in adaptability, and an efficient and reliable supporting solution is provided for underground structure construction and foundation pit safety guarantee.

The invention relates to a parallel loading wing type large-span cantilever truss structure system and a mounting method thereof, the structure system is formed by connecting a plurality of loading wing type trusses which are arranged along the outer edge of a main body structure in parallel at intervals and unfolding wing type trusses on the outermost side in parallel, and the trusses are connected into a space whole through horizontal connecting components. The wing carrying type truss comprises a vertical bearing part and a horizontal overhanging part which are inclined from inside to outside, a wing carrying structure is formed, and overhanging loads are efficiently and obliquely transmitted to a main body structure. Reinforcing components such as three-fork web members are arranged at the ends of the wing-unfolding type trusses, and the rigidity of the ends is enhanced. The mounting method adopts sequential construction of pushing truss by truss from one end to the other end and synchronously connecting horizontal members. The problems that a traditional solid-web cantilever beam is huge in dead weight, insufficient in rigidity and large in building space occupation are solved, and the large-span solid-web cantilever beam has the advantages of being reasonable in stress, small in steel consumption, large in spanning capacity and wide in building space and is suitable for large-span cantilever buildings such as stadiums and terminal buildings.
