no. 3 approach

[0045] The third embodiment: a method for cross-wind protection of roads and bridges. On the windward side of the windshield 2, two arc segments 201, 202 with different curvatures in positive and negative directions are used to initially block and disperse the cross-wind direction, so that the cross-wind is The two arc sections 201, 202 use a plurality of dimples 203 arranged on them to realize the change of the divergent wind direction of the cross wind and the dispersion and weakening of the wind force; each of the windshields 2 The double-layer detachable elastic design of an arc section converts the impact of the cross wind into the compression deformation between the two layers to realize the further absorption and weakening of the cross wind force; the lower arc section 201 is impacted by the cross wind. The maximum deformation point is transmitted to the buffer support tube 6 through the arc-shaped support plate 5 attached thereto for absorption and weakening; The conca...

Abstract

The invention discloses a road bridge crosswind blocking method. On the windward side of a wind blocking plate, crosswind is preliminarily blocked and dispersed to different directions by using two arc sections with different curvature positive and negative directions so that the crosswind are turned over while climbing up along the two arc sections; the two arc sections disperse and change the directions of the crosswind and disperse and weaken the wind power of the crosswind by using a plurality of recessed holes formed in the arc sections; by using a double-layer detachable elastic design of each arc section of the wind blocking plate, the crosswind impact is converted into compressive deformation between double layers to further absorb and weaken the wind power of the crosswind; and atone part, with maximum deformation generated under the crosswind impact, of the lower arc section, the crosswind is transmitted to a buffering supporting tube to be absorbed and weakened by using anarc supporting plate attached to the lower arc section. The road bridge crosswind blocking method has the advantageous effects that the wind blocking plate can generate elastic deformation so as to avoid breakage when the wind power is greater; and the crosswind can be buffered and decelerated for multiple times so that the wind power of the wind blown to a pavement is reduced.

Description

technical field [0001] The invention relates to the field of road and bridge safety, in particular to a road and bridge windshield and a crosswind windshield method. Background technique [0002] With the rapid development of roads and bridges, the following vehicle safety issues are also reflected one by one. Due to the high road surface of road bridges, vehicles driving on the road are often affected by cross winds, which may cause safety accidents. Do occlusion. [0003] The applicant found that there are at least the following technical problems in the prior art: the existing road and bridge windshields have two forms of straight plates and curved curved plates, although they can block the cross wind, but due to the straight plate and the curved curved plate Both are fixedly connected with the mounting base, so when the wind is strong, the windshield will be broken, and the broken windshield will fall on the road, which will not only affect the traffic, but also cause ...
