The frame column, the frame beam and the inclined support are round tubes.
Aiming at the defects of the traditional trestle in the current thermal power generation project, the inventor designs an open-air trestle of honeycomb H-shaped steel, which mainly comprises a side truss structure, a top surface structure, a trestle surface structure, a first trestle frame and a second trestle frame; the side truss structure comprises a front honeycomb H-shaped steel truss and a rear honeycomb H-shaped steel truss which are erected in parallel between the first trestle frame and the second trestle frame and support the top surface structure; the top surface structure is composed of herringbone honeycomb steel beams, and the herringbone honeycomb steel beams are supported and fixed between the front honeycomb H-shaped steel truss and the upper edge of the rear honeycomb H-shaped steel truss; the stack bridge deck structure comprises fish-bellied honeycomb steel beams, and the fish-bellied honeycomb steel beams are supported and fixed between the front side honeycomb H-shaped steel truss and the lower edge of the rear side honeycomb H-shaped steel truss. Because the longitudinal and transverse directions are both honeycomb H-shaped steel, the hollowed-out parts save steel, ensure light transmittance, and have attractive integral appearance, and the longitudinal and transverse pipelines are convenient to arrange. The utility model is more suitable for open trestle engineering, has larger economic span compared with the traditional concrete or solid web steel girder, saves the engineering quantity, is simpler than the truss trestle structural form, has no excessive welding construction, and has lower self weight of trestle because all the components are steel components, and has simpler construction and installation without template engineering. Therefore, the economic span of the open trestle of the honeycomb H-shaped steel can meet the requirements of most scenes, and the steel grating trestle deck can be adopted, so that the vast majority of requirements of the process are met.
