Example Embodiment

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] refer to figure 1 , the composite bridge deck steel box structure of the present invention, the steel box girder is constituted by the bridge deck steel bottom plate 10, two side webs 11 and the bottom plate 12, the bridge deck steel bottom plate 10 is fixedly connected with the two side webs 11, and the diaphragm. The upper surface of the bridge deck steel bottom plate 10 is fixed with vertical shear plates 14 at intervals along the bridge direction or across the bridge direction, and a reinforced concrete layer 20 is poured on the bridge deck steel bottom plate 10 . The shear plate 14 doubles as a longitudinal plate rib or a transverse plate rib.

[0013] The invention effectively solves the technical problems of fatigue performance, thermal stability and combination of paving layer and steel bridge deck in the existing steel box structure bri...

Abstract

The invention discloses a steel box structure of a combined bridge deck. The steel box structure is characterized by light weight, less amount of used steel, good heat stability and durability, and low total engineering cost in a condition of same bearing capacity, and further is beneficial to improvement of the using performance of a bridge. The steel box structure comprises a steel box girder consisting of a bridge deck steel base plate (10), webs (11) at two sides and a bottom plate (12), wherein the bridge deck steel base plate (10) is fixedly connected with the webs (11) at two sides and a transversal clapboard, vertical shear-resistant plates (14) are fixedly arranged on the upper surface of the bridge deck steel base plate (10) at intervals along or vertical to the direction of the bridge, and a reinforced concrete layer (20) is cast on the bridge deck steel base plate (10).

Description

technical field [0001] The invention relates to a steel box structure of a steel bridge, in particular to a steel box structure applied to a composite bridge deck. Background technique [0002] Steel bridges are especially suitable for long-span bridges due to their light weight and high material strength. With the development of my country's infrastructure construction, more and more bridges need to cross rivers, rivers, deep trenches, and canyons. More and more long-span bridges will be built, and steel bridges will also be used more. [0003] Steel box girder is a commonly used form of steel bridge. Generally, steel box girder adopts all-steel structure, which is composed of steel bottom plate, steel web, steel transverse diaphragm and steel bridge deck with U ribs, and epoxy asphalt pavement is laid on it. Floor. However, due to the fatigue performance of the bridge deck, thermal stability, and the combination of the pavement layer and the steel bridge deck, the design...
