Traffic indicating board capable of reducing wind load

Abstract

The invention provides a traffic indicating board capable of reducing wind load. The traffic indicating board comprises a traffic indicating board body (1), a bottom color layer (2), and graphics andtext information parts (3), as shown in figures 1 and 2. The traffic indicating board body (1) is an industrial metal perforated plate, holes are uniformly distributed on the traffic indicating boardbody, and thus the purpose of reducing the wind load is achieved; the metal perforated plate manufactured in batches has the advantages of stable quality, high hole precision and low cost; the holes are uniformly distributed in the traffic indicating board body (1), so that the uniform distribution of the wind load is realized, and then the stability of the indicating board is benefited; and the plate thickness, hole size, hole distance, hole number, hole distribution, hole shape and the like of the indicating board body (1) can be designed and processed according to meteorological conditionsof different regions, then the wind load can be reduced, and the stiffness requirement of the indicating board also can be satisfied. The bottom color layer (2) adopts a reflecting sign coating, the reflecting sign coating is uniformly sprayed to coat the whole traffic indicating board body (1), and the original appearance of the holes in the traffic indicating board body (1) can be maintained. The graphics and text information parts (3) adopt light-reflecting films, after the reflecting sign coating of the bottom color layer (2) becomes completely dry, the light-reflecting films are directlypasted, the clarity and identifiability of traffic information can be guaranteed, and thus the traffic safety is guaranteed.

Description

technical field [0001] The invention relates to the field of traffic facilities, in particular to a traffic sign that can reduce wind load. Background technique [0002] Traffic signs are a kind of traffic facilities that manage traffic order through graphic symbols, which play an important role in ensuring smooth roads and driving safety. The wind pressure, that is, the wind load, on traffic signs, especially taller and larger ones, will affect their stability and pose potential safety hazards. [0003] In order to reduce the wind load of the traffic sign, the existing technology is to set slits or round holes with a certain aperture and hole distance in the blank space of the graphic content on the sign. The CN201812446 patent provides a signboard surface in which regularly arranged small through holes are drilled on the glass steel plate. [0004] There are at least the following problems in the prior art: the efficiency of reducing wind load by setting slits or holes i...

AI Technical Summary

Problems solved by technology

[0004] There are at least the following problems in the prior art: the efficiency of reducing wind load by setting slits or holes in the blank places of the graphic content on the traffic signs is low, and the uneven distribution of the set slits or holes will cause the signs to be damaged. The uneven distribution of wind load in the wind load caused the problem of deformation and instability; drilling holes on the traffic signs, the processing cost is high; although the CN201812446U patent overcomes the above problems caused by the uneven distribution of holes, it does not consider the holes The influence of the number, hole diameter and hole spacing on the stiffness of the traffic sign. If the number of holes is too large, the hole diameter is too large, and the hole spacing is too small, the traffic sign will be deformed, unstable or even dropped due to insufficient rigidity, resulting in another A potential safety hazard; the background color and graphic information on the CN201812446U patent traffic sign is realized by brushing paint, but because the traffic sign board itself is full of holes, the clarity of the parts with holes in the graphic information is not enough, which will affect pedestrians and the driver's recognition of the graphic information on the sign
