Abstract
The invention provides a large-span corrugated steel web continuous rigid frame lining concrete combined web structure which comprises a corrugated steel web section, a corrugated steel web section and a concrete lining section. And the lining concrete section is arranged near the supporting point, is connected with the corrugated steel web section and comprises a flat steel web and lining concrete poured on the inner side of the flat steel web, and a vertical steel beam and a longitudinal steel beam are arranged in the lining concrete. According to the structure, the possibility of cracking of the lining concrete can be reduced, and the durability and stability of the combined web structure are improved.
Description
technical field [0001] The invention relates to the technical field of large-span corrugated steel web continuous beams or continuous rigid-frame bridges, in particular to a large-span corrugated steel web continuous rigid structure lined with concrete composite web structures. Background technique [0002] The corrugated steel web composite box girder bridge has the advantages of light structure, beautiful appearance, reasonable force and economical engineering cost, so it has become a new type of bridge structure that has been vigorously promoted and applied in the construction of highway and urban bridges in my country in recent years. The corrugated steel web composite beam bridge is generally lined with concrete on the corrugated steel web near the fulcrum to prevent the buckling of the fulcrum steel web and ensure the smooth transmission of the internal force at the root. In large-span continuous beam bridges with corrugated steel webs, the span is generally 90~200m. C...
