The invention relates to a planar-bending corrugated
sheet steel beam. The planar-bending corrugated plate steel beam comprises a
flange sheet, a corrugated steel sheet and a stiffened steel sheet, and the
flange sheet is positioned at the top or bottom of the corrugated steel sheet; after the corrugated steel sheet is horizontally sectioned, the top view of the corrugated steel sheet is arc-shaped; after the
flange sheet is horizontally sectioned, the top view of the flange sheet is arc-shaped, and the
radian and the arc-shaped direction of the flange sheet are consistent to the
radian and the arc-shaped direction of the corrugated steel sheet; and the corrugated steel sheet is in
welding connection with the flange sheet. The planar-bending corrugated
sheet steel beam has the characteristics of unified and beautiful profile, low cost and convenient production. More importantly, the planar-bending corrugated
sheet steel beam is suitable for special structures comprising steel beams,
enclosure walls, guardrails and the like satisfying convex surface building exterior walls of
engineering buildings, has a beautiful overall structure and is practical. The planar-bending corrugated sheet steel beam satisfies the structure needs, also satisfies the building profile needs, allows subsequent decorations to be constructed along the profile of the corrugated sheet steel beam, and becomes a structure, building and decoration integrated economic member.
