Technical Field

The utility model belongs to the technical field of bridge construction, and particularly relates to a steel structure bridge curtain board.

Background

The bridge is the life pulse of city infrastructure construction, has "a bridge leads to north and south, and the graben becomes the reputation of journey" from ancient times, and the bridge divide into highway bridge, railway bridge, pedestrian bridge etc. according to the function, and bridge railing, sunshade are the concrete member that is located the bridge edge of a wing (edge), have anticollision, keep apart, waterproof, pleasing to the eye function, and the bridge sunshade of nearly residential area still need have the function of making an uproar falls in the sound insulation.

Traditional bridge curtain construction techniques include "cast in place concrete" curtain techniques, "precast concrete" curtain techniques. The former adopts a method of casting concrete on site to manufacture the curtain board, and has the defects of long construction period, heavy structure and poor appearance quality; the latter is the relatively high cost and complex process of processing precast concrete as a cover in a specialized factory. Therefore, how to design a novel bridge curtain board structure which is simple to manufacture, good in quality and attractive in appearance and can meet various functional requirements is one of the most problems to be solved in the current bridge construction.
