Novel expandable bridge structure based on paper folding structure

Abstract

The embodiment of the invention discloses a novel deployable bridge structure based on a paper folding structure The bridge structure comprises a bridge deck slab and a deployable structure, vertexesof a plurality of first rhombus units are common vertexes, and second rhombus units are connected with the first rhombus units which are adjacent to each other up and down and left and right; and convex vertexes or concave vertexes are arranged on the horizontal symmetry axes of the second rhombus units which are adjacent up and down, convex vertexes and concave vertexes are arranged on the horizontal symmetry axes of the second rhombus units which are adjacent left and right, and gaps are formed between folding structures formed at the convex vertexes and the concave vertexes. The paper folding structure can be completely folded and unfolded into a two-dimensional plane, so that the expandable structure developed by the paper folding structure has a relatively large shrinkage rate; the deployable structure is a multi-degree-of-freedom system, an inhaul cable is adopted for control, deformation coordination is easy to achieve, and the locking phenomenon in the folding and unfolding process is not likely to happen; and overall unfolding and folding of the whole bridge can be achieved, and the construction speed is high.

Description

technical field [0001] The invention relates to a deployable bridge structure, in particular to a novel deployable bridge structure based on an origami structure. Background technique [0002] The expandable bridge is easy to store, takes up little space for transportation, and has a fast construction speed. It has a good application prospect. In recent years, it has received widespread attention from the bridge industry at home and abroad. In order to ensure smooth traffic during field operations, disaster relief, outdoor surveys, and bridge construction and reconstruction, it is necessary to build bridges that meet the requirements of use through rapid construction in a short period of time, and expandable bridges can meet this requirement. Generally, the bridge body of the expandable bridge adopts a special structural form, which is manufactured in the factory. After being closed and folded and transported to the site, it only needs to stretch the bridge body, and then st...
