Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pavement for controlling the traveling speed of a vehicle on a road such as a community zone.

[0002]

[Prior Art] A community zone founded in 1996 to make pedestrians pass, talk, children play, interact with others on residential roads, etc. Needs further promotion of practice for the following reasons.・ The number of traffic accidents and casualties is increasing, and there is a strong demand for accident prevention measures. Regarding pedestrian accidents, the percentage of accidents in the area such as accidents near home is high,
This is especially the case for the elderly and children. -In the area where the community zone has been introduced, significant effects of reducing traffic accidents are being implemented.・ Barrier-free, bicycle, local environment, town development, etc.
It is expected to be an effective method for responding to new needs in recent years.

In the community zone, in addition to clearly indicating the area, traffic restrictions such as one-way traffic and physical devices such as humps and constrictions are applied, which eliminates passing traffic, suppresses the traveling speed of automobiles, etc. A comfortable road space is secured.

With respect to a hump that is paved with a convex cross-section on the road surface of a vehicle and vertically lifts a vehicle passing therethrough with a characteristic according to the speed, the effect of suppressing the speed and the effect of alerting at an intersection are widely recognized. On the other hand, problems with noise and vibration are often pointed out. The biggest factor is the shape of the hump itself, so while maintaining effectiveness and safety,
It is necessary to select and introduce a hump with a shape that can minimize problems such as noise and vibration.

As a countermeasure, in order to maintain the effect and safety and solve problems such as noise and vibration, an appropriate hump shape whose effect has been confirmed and which is under development is selected.

In Europe and the United States, where the introduction of humps is long, the adoption of a sine curve for the ramp (gradient) part of the bow-shaped hump and the trapezoidal hump has become established and has been very effective.

In Japan as well, pavement makers and the like have developed unique hump shapes that apply sine curves, and are being effective. It is hoped that the hump with such a shape will be established as a powerful tool for traffic safety.

Regarding such a hump, Japanese Patent Laid-Open No. 10-3
Japanese Patent No. 7111 proposes a pavement for suppressing the traveling speed of a vehicle in which a pavement surface having a corrugated shape in the longitudinal direction and a phase difference in the transverse direction is provided on the road surface. The pavement for controlling the traveling speed of this vehicle has a sine wave shape with a wavelength of 5 to 35 m, a wave height of 10 to 130 mm, a wavelength number of 2 to 10, and a phase difference of 5 to 80 °. is there. In addition, it is characterized by providing a visual alert function and is characterized by selecting a wavelength, a wave height, and a phase difference according to the speed limit of the road.

[0009]

However, JP-A-10-
The (pavement for suppressing the traveling speed of a hump vehicle) disclosed in Japanese Patent No. 37111 is a pavement material that constitutes a hump.
Appropriate known construction materials can be used, specifically concrete, mortar in addition to cement, resin, asphalt or binder using a combination of these,
It is said that tiles and blocks are preferably used. Due to such non-elastic materials such as cement, resin and asphalt, noise and vibration are great when the vehicle is running.

Further, the thickness of the vehicle entrance end of the pavement is 10
Some are over mm, and the initial noise is large.

The hump disclosed in Japanese Unexamined Patent Publication No. 10-37111 is usually laid on a base made of granular roadbed, asphalt concrete, cement concrete, etc. For the construction, a conventionally known paving machine is used. Although it can be used, it is preferable to use a leveling machine and a compacting machine dedicated to the corrugated path in order to improve the precision of the finished shape. Since the road surface is fixed in this way, it must be destroyed when it is removed, and long-term traffic control is required, including construction.

Further, since the molding is carried out by laying, it takes a long time at the time of repairing, and the shape after repairing is not the same as that at the beginning, there is a possibility that the performance may change and the stability may be unstable.

Although it is conceivable that the entire hump is made of a chip material such as rubber, when the shape of the hump is a sine curve, which is preferable, the parts of the vehicle entrance and exit are compared. Since it is extremely thin, it may roll up, crush, or tear.

The object of the present invention is to eliminate the inconveniences of the above-mentioned conventional example, reduce the generation of noise and vibration, be environmentally friendly, and
It is an object of the present invention to provide a pavement for suppressing the traveling speed of a vehicle, in which the vehicle entrance portion and the vehicle exit portion are along the road surface shape and can bear the traffic load of the vehicle.

[0015]

In order to achieve the above object, the present invention is, firstly, that a pavement body having a sine curve shape in the longitudinal direction is made of an elastomer and provided on a road surface. , The main part of the main body is formed of rubber chips,
The gist of the present invention is that the vehicle entrance and the vehicle exit are made of solid elastomer.

Thirdly, it is composed of a combination of square molded units, and fourthly, the vehicle ascending opening and the vehicle exiting portion have an end thickness of 1 mm to 6 mm and a rounded tip. It is what

According to the first and second aspects of the present invention, noise and vibration can be reduced due to the shape of the sine curve and the elastic body, and further, the solid forming the vehicle entrance and exit. The elastomer or rubber chip composite follows the unevenness of the road, has little curling up, and is durable against crushing and tearing.

Further, anchor bolts, double-sided tape and the like can be fixed to the main body portion and the vehicle ascending / descending portion so that they can be easily removed when unnecessary and the road surface can be easily restored to its current state. Therefore, if there is no effect at the pavement position once constructed, the position can be easily changed to a position where it seems to be effective.

According to the second aspect of the present invention, in addition to the above-mentioned action, since the square molded product unit is manufactured and installed and fixed side by side on the road surface, the construction is easy and the construction can be performed according to the road specifications.

According to the third aspect of the present invention, the noise generated at the step at the time of entering and passing the vehicle can be reduced by minimizing the step between the vehicle ascending entrance and the vehicle exit and the road. .
