Novel RFB construction cementing UHPC-steel bridge deck structure

Abstract

The invention discloses a novel RFB construction glue joint UHPC-steel bridge deck structure, which comprises a steel bridge deck slab, a UHPC-steel bridge deck slab, a UHPC-steel bridge deck slab, a UHPC-steel bridge deck slab and a steel bridge deck slab, the UHPC layer is arranged on the upper side of the steel bridge deck slab; the reinforcing mesh is arranged in the UHPC layer; the upper end of the U-shaped rib is connected with the lower side of the steel bridge deck slab; the transverse partition plate is vertically arranged, the upper end of the transverse partition plate is connected with the lower side of the steel bridge deck slab, and the U rib penetrates through the transverse partition plate and is connected with the transverse partition plate through a novel RFB structure. According to the novel RFB construction cementing UHPC-steel bridge deck structure, the problem of fatigue cracking of welding vulnerable parts of a transverse partition plate, a U rib and a top plate of an existing orthotropic steel box girder bridge under the action of repeated loads of vehicles is solved; and the problems that the prefabricated UHPC pavement plate and the steel bridge deck slab are integrally cast in situ, the construction process is complex, and manpower and material resources are wasted are solved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering construction equipment, and in particular relates to a novel RFB structure glued UHPC-steel bridge deck structure. Background technique [0002] Orthotropic steel bridge deck has outstanding advantages such as light weight, high bearing capacity, and wide application range. It also has strong competitiveness in municipal bridges and bridge reinforcement projects. The traditional orthotropic steel bridge deck often adopts "steel bridge deck + asphalt pavement", but this method is not only prone to fatigue cracking at the weld position, but also frequently causes damage to the asphalt pavement layer. These two types of problems have become the cause of The direct cause of the difficulty in maintenance and repair of orthotropic steel deck pavement. In the construction process of existing orthotropic steel bridges, the pavement is often poured after welding the studs on the steel bridge d...
