Embodiment Construction

[0025] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0026] Suppose there are 45 bridge plates, figure 1 , 2 , 3 are the overall schematic diagram of the unidirectional helical bridge structure.

[0027] The bridge consists of a central girder, an auxiliary girder and a bridge deck. Each subframe is fixed to each bridge plate respectively, and the angle between each bridge plate is 2 degrees. The angle between the first bridge plate and the 45th bridge plate is 90 degrees.

[0028] Figure 4 and Figure 5 A detailed schematic diagram of the bridge deck support structure. The supporting structure of the bridge deck is composed of supporting subbeams, supporting main girders and bridge deck fixing plates.

[0029] Figure 6 -a to Figure 6 -e is a schematic diagram of a single row of a unidirectional helical bridge. This diagram explains how a one-way helical bridge works. which from Figur...

Abstract

The invention discloses a one-way spiral bridge which comprises a central beam, a plurality of bridge plate units and a rotating device used for enabling the central beam to rotate at a constant speed. The bridge plate units are evenly fixed to the central beam, the angle formed by the bridge plate units and the central beam is 90 degrees, the lengths of the positions, on the two sides of the central beam, of the bridge plate units are equal, the bridge plate units form a fixed angle, a spiral structure in the direction of the axis of the central beam is formed, the angle between the bridge plate unit at one end of the central beam and the bridge plate unit at the other end of the central beam is larger than or equal to 60 degrees, the accumulated angle formed by the whole bridge can reach 90 degrees, and an object crossing the bridge can only cross the bridge in the specific direction at the specific speed through the active rotation of the spiral bridge. The bridge has the one-way passing function, and meanwhile the one-way spiral bridge is a novel flag building with entertainment and safety and is easy to implement.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a one-way spiral bridge. Background technique [0002] The existing bridge structure consists of the lower piers, abutments and foundations and the upper span structure. In the traditional sense, bridge types are generally divided into girder bridges, arch bridges, suspension bridges and so on. Their common feature is that the bridge deck is horizontal and static. [0003] Existing bridges are basically two-way traffic, unless artificially restricted, it is basically impossible to realize the function of one-way traffic, and the existing bridges are generally similar in structure, the bridge deck is smooth and stable, and the entertainment is poor. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a one-way spiral bridge for the defects of the background technology, which can realize one-way passage under the premise that peopl...
