Steel concrete combined bridge front panel

Abstract

The invention discloses a steel-concrete composite deck, which is provided with light weight, low steel quantity, comprising deck beam which is grid beam frame formed by fixing longitudinal and cross beams set in a certain distance; steel bottom plate, which is set in each grid of deck beam and is fixed with longitudinal and cross beams; shearing resistance plate, which is set on the longitudinal direction of deck in a certain distance and is welded with the steel bottom plate; and reinforced concrete layer, which is poured on the steel bottom plate. The beneficial effect of invention is that steel bottom plate, reinforced concrete layer and grid beam frame are connected to improve the whole rigidity of bridge. Under the condition of the same load capacity, it can decrease the deck weight and steel quantity at the larger amplitude so as to be favor of decreasing the cost of bridge. It is provided with comfortable vehicle and good wind resistance. It is especially adaptable for decks of large bridge and super-large bridge.

Description

technical field [0001] The present invention relates to bridges, and more particularly to bridge decks for bridges. Background technique [0002] In the structure of bridges, the commonly used bridge decks include concrete decks, laminated decks and steel decks. Concrete bridge decks and laminated bridge decks have a relatively large dead load, resulting in a relatively large overall dead load of the bridge, which makes bridge installation difficult and affects the overall economy of the bridge. Look, the design and construction are more difficult, and few achieve the expected results in actual use, and the large amount of steel used and the high unit price of pavement materials result in high overall cost. Therefore, in order to make the bridge deck have the characteristics of light weight, less steel consumption and low overall project cost, one of the ways is to use steel-concrete composite bridge deck. This structure can give full play to the respective mechanical advan...
