The invention relates to a splayed lattice type truss steel supporting structure which comprises an end truss steel support and a pair of symmetrically-arranged inclined strut structures. The end truss steel support comprises at least two supporting units which are sequentially connected, each supporting unit comprises a pair of parallel main stress rods, a connector is arranged at the end of each main stress rod, a large lug plate is arranged on the outer side of each connector, and a pair of small lug plates which incline forwards and backwards and are used for being hinged to the cross-shaped diagonal web members are arranged on the inner side of each connector. The inclined strut structure comprises a pair of parallel inclined struts, and the upper ends of the inclined struts are provided with lug plate connecting pieces used for being hinged to the large lug plates. The end part of the truss adopts an inclined strut reinforcing structure, so that the bearing range of the truss is enlarged, the excavation space is enlarged, and the steel consumption is reduced.
本发明涉及一种八字型格构式桁架钢支撑结构，包括端部桁架钢支撑和一对对称设置的斜撑结构；所述端部桁架钢支撑包括依次相连的至2个支撑单元，每个支撑单元包括一对平行的主受力杆，所述主受力杆的端部设有连接头，所述连接头外侧具有一大耳板，内侧具有倾斜向前和倾斜向后的一对用于与十字斜腹杆铰接的小耳板；所述斜撑结构包括一对平行的斜撑，所述斜撑的上端具有用于与所述大耳板铰接的耳板连接件。本发明桁架端部采用斜撑加强结构，增加桁架的承载范围，增大开挖空间，减少用钢量。
