The utility model belongs to the technical field of
steel structures, and particularly relates to a constructional
engineering steel structure with a diversion function, which comprises a
steel frame, a triangular support arranged above one side of the
steel frame, a first mounting hole arranged above one side of the
steel frame, a connecting component arranged inside the first mounting hole, and a cross beam arranged on one side of the first mounting hole of the steel frame. A second mounting hole is formed in one side of the cross beam. Through mutual cooperation of the protection plate, the flow guide groove, the water drainage opening and the flow guide
pipe, the steel structure has the flow guide function, and the problem that when the steel structure is in rainstorm weather, accumulated water is prone to being accumulated on the top, and
corrosion of steel is accelerated is solved; through mutual cooperation of the triangular support, the first mounting hole, the connecting rod, the sealing piece, the forward thread, the forward locking nut, the reverse thread, the reverse locking nut and the second mounting hole, the problem that connection between
steel structures is extremely prone to being fixed unfirmly along with the increase of
service time is solved.
