Abstract

The invention discloses a fully prefabricated composite bridge deck structure, which includes several prefabricated thin-layer UHPC bridge decks, corrugated steel plates and supporting components; a number of evenly distributed connecting bolts are pre-embedded in the prefabricated thin-layer UHPC bridge deck; the upper ends of the connecting bolts are buried In the prefabricated thin-layer UHPC bridge deck, its lower end protrudes out of the prefabricated thin-layer UHPC bridge deck; there are a number of bolt holes corresponding to the positions of the connecting bolts on the top of the corrugated steel plate; through the cooperation of the bolt holes and the connecting bolts, the corrugated steel plate and the prefabricated The fixed connection of the thin-layer UHPC bridge deck; the bottom of the corrugated steel plate is set close to the support assembly; the support assembly includes several prefabricated concrete slabs; the upper surface and the lower surface of the two sides of each precast concrete slab are respectively buried with an upper steel plate and a lower surface. Steel plate; a number of shear connectors are evenly distributed on the lower surface of the upper steel plate and the upper surface of the lower steel plate; the connection between two adjacent prefabricated concrete slabs is realized through the cooperation of the tenons embedded in the concave tenons.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a fully prefabricated composite bridge deck structure. Background technique [0002] The orthotropic steel deck is a structure composed of vertical and horizontal stiffeners (longitudinal ribs and transverse ribs) and deck cover plates that jointly bear the wheel load. Due to the fact that the stiffness of this structure is different in two directions perpendicular to each other, it causes structural orthotropy. However, under the action of moving loads, the bridge deck will produce longitudinal and transverse deformations, which will drive the reciprocating deflection deformation of the longitudinal ribs. Since this deformation is constrained by the connecting welds, it will inevitably occur at the joints of the welds. At the same time, because the inside of the stiffener cannot be welded, fatigue cracks often occur. Moreover, the existing orthotropic ste...
