Document Type and Number:
WIPO Patent Application WO/2022/188666
Kind Code:
A1
Abstract:
A combined bridge deck structure for a bridge, and a bridge structure and a construction method therefor. The bridge deck structure comprises a top plate (1) and longitudinal ribs (2) fixed on the lower surface of the top plate (1), and further comprises transverse ribs (3) assembled above transverse partition plates (4) of a main beam structure (5) of the bridge; the longitudinal ribs (2) are fixedly connected to the transverse ribs (3), and are connected to the transverse partition plates (4) by means of the transverse ribs (3); and openings for accommodating the longitudinal ribs (2) are not provided on the transverse ribs (3). According to the combined bridge deck structure, the longitudinal ribs (2) and the transverse partition plates (4) are connected by means of the transverse ribs (3) such that an operation of forming openings on the transverse partition plates (4) is avoided, and the stress generated by openings is reduced; section steel, other than a welded steel plate, serve as the longitudinal ribs (2) and the transverse ribs (3) such that welding seams are decreased; and by disposing section steel in a high-stress area and forming welding seams in a low-stress area, fatigue resistance capability of the bridge deck structure is improved.
