Abstract

The invention discloses an orthotropic steel plate-composite material hollow slab combined bridge floor structure. The bridge floor structure comprises an orthotropic steel plate, a composite material hollow slab and a wearing layer, wherein the upper side of the orthotropic steel plate is sequentially provided with the composite material hollow slab and the wearing layer; the composite material hollow slab is connected with the orthotropic steel plate on the lower side through a structural adhesive; the top of the composite material hollow slab is provided with a rough surface layer; the wearing layer is poured on the upper side of the rough surface layer; the composite material hollow slab comprises two parts, namely a top plate and a bottom plate; and the top plate and the bottom plate are connected through cement and bolts to form the composite material hollow slab. The orthotropic steel plate-composite material hollow slab combined bridge floor structure has the advantages of light weight, high strength, high rigidity, high peel strength, moisture protection, corrosion resistance, stable high-temperature stability and low-temperature crack resistance; and meanwhile, the orthotropic steel plate-composite material hollow slab combined bridge floor structure has the obvious characteristics of simple, convenient and rapid construction assembly, water resistance, pavement layer cracking resistance, orthotropic steel bridge floor surface corrosion and the like and is suitable for construction and repair of various steel bridge floor structures.

Description

technical field [0001] The invention relates to the technical field of bridge deck pavement structures, in particular to a composite bridge deck structure that can be used as a composite bridge deck in bridge structures, specifically a light-weight, high-strength, corrosion-resistant factory prefabricated orthogonal deck structure. Heterotropic steel plate-composite material hollow slab combined bridge deck structure. Background technique [0002] The traditional orthotropic steel deck system is mostly composed of orthotropic steel deck and asphalt mixture pavement. As the operation time increases, it is easy to cause damage to the asphalt mixture pavement layer and fatigue cracking of the steel bridge deck structure, causing potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a factory-prefabricated orthotropic steel plate-composite material hollow plate composit...
