Abstract

The invention provides a construction method of a prefabricated bridge deck steel-concrete composite beam, and relates to the technical field of bridges. The construction method comprises the steps ofprefabricating a bridge deck: pouring concrete into bridge deck sections with a plurality of shear grooves with the top surfaces not communicating with one another; arranging shear connecting parts:welding the plurality of shear connecting parts on the top surface of the steel beam; erecting the bridge deck: erecting the bridge deck sections on the top surface of the steel beam, and enabling each single shear connecting part to penetrate into the corresponding shear groove; carrying out grouting connection: pouring cement slurry into the shear grooves; and splicing the bridge deck: pouring awet joint between every two adjacent bridge deck sections. According to the construction method of the prefabricated bridge deck steel-concrete composite beam, the problem that the damage and failureof connection between the bridge deck and the steel beam of the prefabricated bridge deck steel-concrete composite beam is caused by insufficient concrete filling in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a construction method of a prefabricated bridge deck steel-concrete composite beam. Background technique [0002] With the development of society and the advancement of science and technology, bridge construction technology is also constantly optimized. Steel-concrete composite beams are composed of concrete bridge decks and steel beams connected by shear connectors, which make full use of the properties of concrete and steel materials, have good mechanical properties and economical efficiency, and are widely used in engineering . At present, the construction methods of steel-concrete composite girder bridge deck mainly include cast-in-situ construction method and prefabrication construction method, among which prefabrication construction method is more and more widely used. [0003] In the prefabricated construction method, the combination of prefabricated bridge deck segments...
