Description

technical field [0001] The invention relates to the field of bridges, in particular to an improved bridge device. Background technique [0002] With the continuous improvement of people's living standards and the continuous increase of traffic, more and more traffic is driving on bridge roads, which requires traffic police to direct traffic. In hot summer or rainy days, traffic police need awnings or awnings when directing traffic Covering devices such as awnings are used to avoid heat and rain. The traditional covering devices have a simple design and structure, are inconvenient to disassemble, and cannot change the distance between the pillars of the covering device as required, neither can change the occupied area of ​​the covering device. Contents of the invention [0003] The object of the present invention is to provide an improved bridge device capable of overcoming the above-mentioned drawbacks of the prior art. [0004] According to the present invention, an impr...
