Large-span photovoltaic steel truss structure

The invention relates to the technical field of photovoltaic supports, and discloses a large-span photovoltaic steel truss structure which comprises a supporting part and a frame part arranged on the supporting part. The supporting part comprises a plurality of supporting beams, connecting parts connected to the two ends of the supporting beams and installed on the suction piles, and reinforcing beams connected between every two adjacent supporting beams. A plurality of connecting nodes are installed on the supporting beams at intervals in the length direction, a reinforcing rod is connected between every two adjacent connecting nodes on the same supporting beam, and the reinforcing beams are also connected to the connecting nodes. The space below the steel truss can be enlarged, so that operation of a fishing boat is more convenient, and the steel truss has good stability. 本申请涉及光伏支架的技术领域，公开了一种大跨度光伏钢桁架结构，包括支撑部以及设置于所述支撑部上的框架部；所述支撑部包括多个支撑梁、连接于所述支撑梁两端且安装于吸力桩上的连接部以及连接于相邻两个所述支撑梁之间的加固梁；所述支撑梁沿长度方向间隔安装有多个连接节点，同一所述支撑梁
