Road ceramic marking line and ceramic piece and manufacturing method thereof

Abstract

The invention relates to a road symbol, which can provide a road ceramic symbol line with anti-slip, reflecting and blind-man-recognize functions. It is formed by several ceramic sheets arranged on the road, while said ceramic sheet comprises a first surface, a second surface and side surfaces. Wherein, the first and second surfaces are opposite; the side surfaces connect the first and second surfaces, while comprises inclined surfaces; at one inclined surface comprises a straight surface vertical to said first surface; the second surface is fixed on the road; the straight surface is higher than the road; and the straight surfaces of each ceramic sheets are toward to same direction. The invention is firm, anti-slip, reflecting and blind-man-recognize, which can be applied in the construction of road symbol line.

Description

technical field [0001] The present invention relates to road accessory equipment and its manufacturing method, in particular to road signs and its manufacturing. Background technique [0002] Worldwide, the current road markings mainly use hot-melt reflective coatings, cold-spray solvent-based coatings, and preformed plastic marking tapes. As of now, there are no pedestrian crossings for the blind. The traditional organic glue as the main material is easy to stick to dirt and turn black, and the self-cleaning power is too low. In some areas, the line will be dirty and invalid after three days, and it will age and fall off in half a year. Repeated line marking is a waste of manpower and material resources. It is difficult to meet the technical standards required by the traffic law, leaving hidden dangers to traffic safety. [0003] As early as the 1950s, the United States took the lead in using Φ100-150mm hemispherical ceramics as road marking materials on highways. Many h...

Problems solved by technology

However, this kind of road sign embedded in ceramics is not slippery, and the repaired road cannot be installed with ceramics, and the problem of night reflection is not considered

[0005] In 1987, Qian Hongcheng invented the patent No. 86202906. The ceramic reflective raised marker road sign was used on the 83-kilometer highway from Shanghai Fengjing to Hangzhou. It used to replace paint markings in two years. The quantity is very large, only used for a year and a half
