Y-shaped steel member of steel and concrete composite girder
The invention discloses a Y-shaped steel member of a steel and concrete composite girder, which belongs to the field of bridge construction. The Y-shaped steel member comprises an upper wing plate, a lower wing plate and a web plate which is used for connecting the upper wing plate and the lower wing plate, wherein the two side parts of the upper wing plate are horizontal; the middle part of the upper wing plate is concave downwards; and the upper wing plate is combined with the web plate, which is positioned under the upper wing plate, to form a Y shape. An anti-shear connecting piece is arranged on the upper surface of the upper wing plate of the Y-shaped steel member; after concrete is poured above the Y-shaped steel member, a composite girder can be formed. Through the adoption of the composite girder, the height of a steel web is reduced in case of equivalent girder height; and a diagonal plate or a diagonal bracing does not need to be additionally arranged at the joint part of a top plate and the web plate. The Y-shaped steel member is advantaged in that the torsional stiffness and flexural rigidity of the section of the member are improved, torsion stress and distortion stress of the member are reduced and force line transition of the member is uniform. Meanwhile, the anti-shear strength of the member is improved and a bridge deck slab and a girder are not prone to be dislocated relatively.
