Abstract

The utility model relates to a rubber way tooth device, it includes body (1), and body (1) covers on thick rubber district (2) including inside thick rubber district (2) and outside thin rubber district (3), thick rubber district (2) used rubber granule is 8-15 mm's rubber granule, and thin rubber district (3) used rubber granule is 1-8 mm's thin rubber granule. The utility model is environment-friendly and beautiful, has long service life, elasticity and strength; the flexible contact between the rubbing strip and the vehicle reduces the direct friction and collision between the wheel hub steel ring and the road teeth, and prevents the wheel hub of the trolley from being extruded and scraped or even damaged.

Description

Rubber curb device

Technical Field

The utility model relates to an urban road facility technical field, specifically speaking relate to a rubber road tooth device.

Background

Road isolation is to arrange an isolation strip in the center of a road or to isolate a roadway from a sidewalk, and is to distinguish the boundaries of the roadway, the sidewalk, a green land, the isolation strip and other parts of the road on the road surface, so as to play a role in guaranteeing the traffic safety of pedestrians and vehicles and ensuring the neat edges of the road surface.

The existing road isolation method mainly uses road teeth for isolation, the common types of the road teeth are vertical type and L type, and the road teeth are generally prefabricated by concrete. The defects are as follows: 1. because the road teeth are generally made of bricks or concrete, the road teeth are smooth and hard, when a vehicle walks nearby, the vehicle is easy to roll the road teeth, the vehicle is easy to scratch and damage, and even the quality of a hub is reduced, and the safety of the vehicle is influenced. 2. The existing road teeth are gray and have small color contrast with the road, so that a driver cannot accurately judge the boundary between the road and the sidewalk when driving a vehicle, and traffic accidents are easily caused. 3. Although the cement concrete road dental calculus is cheap, the service life is short, the replacement is carried out periodically, the labor and the materials are wasted, and a drainage ditch is specially arranged to solve the drainage problem. Although the service life of marble and granite curbstone is long and beautiful, the price of the marble and granite curbstone is very high, which causes great expenditure on road cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned not enough, provide a rubber way tooth device, the environmental protection just beautifies the road, long service life, and is elastic promptly and has intensity again.

The purpose of the utility model is realized like this:

a rubber curb device comprises a body, wherein the body comprises an inner coarse rubber area and an outer fine rubber area, the fine rubber area covers the coarse rubber area, rubber particles used in the coarse rubber area are 8-15mm rubber particles, and rubber particles used in the fine rubber area are 1-8mm fine rubber particles.

A smooth cambered surface which is recessed inwards is arranged on the outer side surface of the thin rubber area, and the upper part and the lower part of the cambered surface are connected smoothly through chamfers.

The outer side surface of the thin rubber area is a smooth curved surface.

A rubber curb device, the fine rubber zone adds 2% -10% EPDM colored rubber granule.

A plurality of rubbing strips are arranged on the outer side surface of the thin rubber area.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model takes the coarse rubber particles as the substrate inner layer and the fine rubber particles as the surface layer, the coarse rubber particles have the characteristics of ageing resistance, corrosion resistance, good tensile strength, hardness and the like, the fine rubber particles have the characteristics of softness, good elasticity, strong impact resistance and the like, the elasticity of the road teeth is ensured, and the fine rubber particles have high hardness of the inner core and can play a good role in buffering when in use; the coarse rubber particles are arranged in the inner part and have a penetrating effect, so that water drainage is facilitated, and a water drainage hole is not required to be additionally arranged; the thin rubber area of the surface layer can be made into colors, so that the road is environment-friendly and attractive, the service life is long, and the road is elastic and strong; the protruding rubbing strip has increased the friction between curb and the vehicle, and the flexible contact between rubbing strip and the vehicle has reduced direct and the curb friction of wheel hub steel ring, collision, prevents that dolly wheel hub from being extrudeed the scraping, the condition of damage even.
