Title:
LONGITUDINAL STIFFENER STRUCTURE CAPABLE OF ENHANCING ROBUSTNESS OF SUSPENSION BRIDGE SYSTEM OF HALF-THROUGH ARCH BRIDGE AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/156109
Kind Code:
A1
Abstract:
A longitudinal stiffener structure capable of enhancing robustness of a suspension bridge system of a half-through arch bridge and a construction method therefor. An effect of mounting the longitudinal stiffener structure between two cross beams (11) is achieved by sleeving large tube units (1) and small tube units (2) one another, inserting the large tube units (1) and the small tube units (2) into supporting tube units (5), and mounting anchoring steel plate units (3). The present invention has the advantages that: the steel-structured longitudinal stiffener is light in weight, large in stiffness and easy to connect, the overall stiffness and stability of the suspension bridge system are greatly improved, inconsistent deformation caused by temperature change of a bridge deck and the longitudinal stiffener can be fully released, an impact forced generated by the fracture of a hanger can be borne on a certain length, and the robustness of the suspension bridge system is enhanced; and the present invention can effectively avoid major accidents, and achieves good economic value and social effect.
