Description

Concrete kerbstone with glass bead reflective layer

Technical Field

The utility model belongs to the town road field relates to a road side stone structure, in particular to take concrete curbstone of glass bead reflector layer.

Background

Along with the progress of urbanization in China and the development of urban road traffic, cities in various regions pay more and more attention to the construction of road traffic signs and marking lines, and the road traffic marking lines are necessary for urban road traffic safety, namely traffic signal facilities formed by various lines, arrows, characters, three-dimensional marks, protruded road signs, road side line contour marks and the like marked on the road surface. The road traffic marking line has the functions of separating motor vehicles, non-motor vehicles and pedestrians, improving the road utilization rate, reducing or preventing traffic accidents, and improving the effectiveness of the road traffic marking line by being matched with traffic signs and traffic signals.

In urban roads, particularly main roads, curbstones are generally arranged on the sides of the roads, the inner sides of the curbstones face the roads, and the curbstones are the outermost side structures of the roads. The reflective edge lines and the reflective sheets need to be constructed or installed later, after the reflective edge lines are used for a long time, the abrasion is easily reduced, the reflective performance is poor, the reflective sheets are convexly installed on the surface of the kerbstone and can be collided to fall off, and when the wheels rub the reflective sheets, the rubber of the wheels can be scratched, so that potential safety hazards are generated.

Disclosure of Invention

The utility model aims to solve the reflection of light sign at present roadside sign road edge and need construct the installation, and have the reflective performance variation after using for a long time, wearing and tearing drop the scheduling problem, a take the concrete curbstone of glass bead reflector layer is provided, set up glass bead layer on the surface of concrete curbstone, reach the effect of reflection of light sign road profile, and glass bead layer sets up and does not expose in the indent structure of concrete curbstone, even the vehicle tyre extrudes the curbstone, can not wear and tear the wheel yet.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a take concrete curbstone of glass bead reflector layer, includes the curbstone body of concrete material, and the curbstone body is inboard towards one side of road, its characterized in that: an inwards concave horizontal long groove is formed in the position, higher than the ground, of the inner side face of the kerbstone body, and a glass bead layer is arranged on the groove wall of the horizontal long groove. According to the scheme, the glass beads are sprayed on the surface of the horizontal long groove at the initial setting stage of the concrete curb forming to form a glass bead layer, so that the light reflecting effect is achieved. The hardness of the glass beads is far higher than that of the concrete kerbstone, the surfaces of the glass beads are uneven, if the glass beads are exposed on the surface of the concrete kerbstone, when an automobile tire carelessly scrapes the kerbstone, the tire is easily scratched, and the glass bead layer can be damaged by the generated huge friction force, so that the light reflecting effect is lost, particularly after the kerbstone is used for a long time, the concrete material becomes brittle and is easily damaged.
