Connecting structure of corrugated arched steel plates and steel beams

Abstract

The invention discloses a connecting structure of corrugated arched steel plates and steel beams. The connecting structure comprises the steel beams, welding studs, angle steel, transverse stiffeningribs, the corrugated arched steel plates and rubber sealing strips. The welding studs are welded and fixed in the middle of the upper surfaces of the top flanges of the steel beams; a horizontal limbof the angle steel is welded and fixed on the upper surfaces of the upper flanges of the steel beams, vertical limbs of the angle steel are close to one outer edge of the upper flanges of the steel beams, and the horizontal limb of the angle steel is close to the welding studs; the transverse stiffening ribs are triangular plates and are perpendicular to the angle steel, and two right-angle sidesof the transverse stiffening ribs are respectively welded on the vertical limb and the horizontal limb; the two ends of the corrugated arched steel plates are kept in horizontal contact with the upperflanges of the steel beams and are kept in vertical contact with the vertical limbs of the angle steel; and the rubber sealing strips are adhered to contact gaps between the corrugated arched steel plates and the angle steel. Compared with like products in the prior art, the connecting structure has the following advantages: the ends of the corrugated arched steel plates can be prevented from leaking a slurry and sliding in the transverse direction of the bridge during concrete pouring, construction is simple, the quality is easy to guarantee, and the construction speed is high.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a connection structure between a corrugated arched steel plate and a steel beam. Background technique [0002] Composite bridge decks are generally composed of steel plates and concrete, among which steel plates are mostly flat steel plates, and stiffeners are welded on them, relying on the stiffeners to provide the necessary rigidity to meet the rigidity requirements of concrete construction. When connecting with the steel beam, usually the flat steel plate is directly welded on the upper flange of the steel beam first, so that the flat steel plate and the upper flange are airtightly connected as a whole, so as to ensure that no grout leakage occurs when pouring concrete. [0003] In engineering, corrugated profiled steel plates and concrete are also used to form composite bridge decks. During construction, the profiled steel plate is placed horizontally on the uppe...

AI Technical Summary

Problems solved by technology

The problem of the connection between the corrugated arched steel plate and the steel beam is more prominent: firstly, the end profile of the corrugated steel plate is a sinusoidal curve or a multi-segment continuous circular curve, which is extremely inconvenient to operate when it is blocked with a flat steel plate, and continuous welding is used. When connecting the corrugated steel plate and the flat steel plate, the welding is difficult due to the thinness of the plate and the continuous curve change; and when the arched form with variable cross-section is used, the steel arch is supported by the upper flange of the steel beam during the pouring of concrete Slippage occurs in the transverse bridge direction, resulting in changes in the cross-sectional dimensions of the arched composite bridge deck
