Construction process of connecting structure of corrugated arched steel plate and steel beam

Abstract

The invention discloses a construction process of a connecting structure of a corrugated arched steel plate and a steel beam, which comprises the following steps of welding a triangular steel plate with the same size as the inner contour of angle steel onto the angle steel to form a component with a plurality of transverse stiffening ribs, welding a welding stud and the component to the upper flange of the steel beam, enabling the corrugated arched steel plate to stretch across two adjacent steel beams, and keeping the two ends of each corrugated arched steel plate in horizontal contact with the upper flanges of the steel beams and in vertical contact with the vertical limbs of the angle steel, adhering a rubber sealing strip to a gap, in contact with the angle steel, of the upper surfaceof the corrugated arched steel plate, placing steel bars on the upper portion of the corrugated arched steel plate according to the size required by design, conducting binding, and then pouring concrete. Compared with the prior art, the process has the advantages that the end of the corrugated arched steel plate can be prevented from leaking 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 construction process for 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 plac...

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
