  The present invention relates to a vehicle deceleration hump, and more particularly to a vehicle deceleration hump installed on a road in order to suppress the traveling speed of a vehicle in a factory or a community zone.

  2. Description of the Related Art Conventionally, a hump formed of resin, rubber, or the like is known as a vehicle deceleration hump (hereinafter also simply referred to as a hump) installed on a road in order to suppress the traveling speed of the vehicle.

  As shown in FIG. 12, this conventional hump has an elliptical top surface and a vertical cross-sectional shape formed in a semicircular bowl shape as shown in FIG. It is fixed on the asphalt road 102 with a bolt 103 or the like so as to intersect with the traveling direction K of the vehicle.

  Thus, by providing the hump 101 on the road 102, the vehicle driver can decelerate in order to avoid an impact caused by riding on the hump 101, or the vehicle can be moved on the hump 101 without decelerating. When the vehicle passes, a strong impact is applied to the vehicle, so that the driver can be urged to reduce the traveling speed of the vehicle.

  In the case where the conventional hump 101 is fixed on the asphalt road 102, when the tire of the vehicle traveling in the direction of the arrow K gets over the hump 101, the vehicle is placed on the road 102 after overcoming the hump 101. The impact 104 is applied, and the eaves 104 are formed on the road 102 after the hump 101 passes through the vehicle. Therefore, it is necessary to periodically repair the asphalt (road) 102.

  However, when the hump 101 is installed near the entrance of the factory, when repairing the asphalt 102, it is necessary to stop the entry of the vehicle into the factory for a certain period of time, but the factory operates for 24 hours. If it is, there is a problem that the time cannot be taken and it is difficult to repair the digging.

  Accordingly, an object of the present invention is to provide a vehicle deceleration hump that prevents the digging.

In order to solve the above-mentioned problem, the invention according to claim 1 has a base portion and a raised portion that rises from the base portion and promotes reduction in the traveling speed of the vehicle,
The base and the bulge are formed in a long shape, and the length in the short direction of the bulge is set shorter than the length in the short direction of the base,
The raised portion and the base portion are formed of concrete.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, the color of the concrete used for the surface layer portion of the raised portion is different from the color of the concrete used for other than the surface layer portion of the raised portion. is there.

  The invention described in claim 3 is characterized in that, in the invention described in claim 1 or 2, a drainage portion is provided in a direction orthogonal to the longitudinal direction of the raised portion.

  A fourth aspect of the invention is characterized in that, in the invention of the first, second, or third aspect, the raised portion and the base portion are integrally formed.

  The invention according to claim 5 is characterized in that, in the invention according to claim 1, 2 or 3, the raised portion and the base portion are formed separately.

  In the hump of the present invention, the base portion and the raised portion that protrudes from the base portion are formed of concrete harder than asphalt, and the length in the short direction of the raised portion is set shorter than the length in the short direction of the base portion. Thus, as compared with the conventional technique, it is possible to suppress the formation of ridges at the base due to the impact of the vehicle over the ridge, and to reduce the number of repairs of the road around the hump.

  In addition, since the raised portion is formed of concrete, the service life can be made longer than a conventional hump formed of resin or rubber, and the number of replacements of the hump can be reduced.

  According to the invention described in claim 2, the color of the concrete used for the surface layer portion of the raised portion is different from the color of the concrete used for the other portion, so that the replacement of the hump is caused by the change in the color of the raised portion. You can get to know the time.
