Bridge span assembly of open web condup-shaped pedestrian bridge

Abstract

The invention relates to a bridge span assembly of an open web condup-shaped pedestrian bridge. The bridge span assembly comprises folding beams provided with turns in a vertical direction. The two folding beams are overlapped up and down in a crossed manner, an attachment strap is arranged between upper turning points of the two folding beams, and the two folding beams and the attachment strap form a bridge floor; and the overlapped part of the two folding beams, the attachment strap and the folding beams arranged below the attachment strap are connected through a web members. Compared with the prior art, the bridge span assembly can be suitable for wiring a condup bridge floor, is relatively high in stability of a large span fold line bridge, and has the advantages that the bridge span assembly is stable in structure, low in processing cost and open in view of bridge floor and a observation deck does not cause an added burden of the bridge floor and the like.

Description

technical field [0001] The invention relates to the field of buildings and pedestrian bridges, in particular to a bridge span component of an empty double zigzag linear pedestrian bridge. Background technique [0002] Traditionally, there are four types of bridge structure systems: beam bridges, arch bridges, suspension bridges, and rigid frame bridges. With the development of building materials and design technology in modern times, some new bridge systems have been derived on the basis of the four major types of bridges. Such as cable-stayed bridges, suspension bridges, etc. [0003] According to the number of span structures of the bridge, it can be divided into single-span, two-span, three-span, multi-span and so on. The fewer the number of bridge spans, the less the lower piers are needed. Since the piers will affect the passage of the waterway, and their construction is generally underwater, the construction is expensive, difficult and risky. Under the conditions of...

Problems solved by technology

However, general bridges are not well adapted to these curved bridges due to traffic or landscape considerations.

It is often necessary to adjust the traffic function or landscape to accommodate the design of the bridge, resulting in a certain impact on the function or appearance

[0005] As for pedestrian bridges, generally speaking, the landscape in the center of the river is relatively open, the airflow conditions are good, and people feel more comfortable. Pedestrians are more likely to stay in the center of the bridge. In architectural design, it is sometimes desirable to set up a landscape platform in the middle of the span, but If a traditional bridge structure needs to set up a platform, it can only be cantilevered from the side, which will bring additional burdens such as overturning to the main structure
