BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road barricade which regulates a traffic section of a vehicle.

[0002]

2. Description of the Related Art When road construction is carried out, a road barricade is installed on the road surface in order to secure a working space at the construction site and at the same time allow the vehicle to run while avoiding the construction site. There are restrictions on traffic classification.

As the road barricade used for such a purpose, foldable simple road barricades are arranged side by side on the road surface when the construction period is short.
When the construction period is long, H-section steel is installed on the road surface so that the web is horizontal, and a road barricade in which a fence is fixed to the H-section steel web by welding so as to stand upright from the web. Is often used.

[0004]

[Problems to be Solved by the Invention] However, a road barricade in which the folding simple road barricade is arranged on the road surface does not have a defense function against the contact of a traveling vehicle and impairs the appearance of the street. There is a problem.

Further, a barricade for a road, in which the above H-section steel is installed on a road surface and a fence is fixed to the web thereof, is heavy, so that the installation position is moved when a traveling vehicle comes into contact with the road barricade. Since it does not occur, there is a large impact when the traveling vehicle comes into contact with it, which causes many accidents resulting in injury or death. Further, the above H-section steel is 300 mm even if the height of the upright flange is large.
However, even if the tires of the traveling vehicle come into contact with the vehicle from a diagonal direction, an accident such that the tire of the traveling vehicle gets over the H-section steel and jumps to the opposite side of the road barricade is likely to occur. There is a point.

Further, the road barricade using the H-shaped steel as described above requires a lot of man-hours because welding is included in the installation work, and the appearance is not good.

In view of the above, the present invention has a function of being easily assembled and installed on a road surface, having a good appearance, and having a function of preventing a traveling vehicle from passing over when the traveling vehicle comes into contact with the vehicle from an oblique direction. It is intended to be a road barricade.

[0008]

In order to achieve the above-mentioned object, the invention of claim 1 combines a base member which is highly stationary with respect to a road surface and a guide member supported by the base member. The road barricade has improved safety, improved appearance, and is easy to transport and install.

When a tire of a traveling vehicle comes into contact with the road barricade from an oblique direction, the guide member attempts to turn the tire toward the longitudinal direction of the road.

[0010] Specifically, the solving means devised by the invention of claim 1 is a base member extending in the longitudinal direction of the road, which is placed on the road surface and has a weight which is difficult to move by the lateral pressure applied by the contact of the traveling vehicle, Provided on the side of the base member,
A plate-like main body extending in the longitudinal direction of the road having an inclined surface for diverting the direction of the tire of the traveling vehicle contacting from an oblique direction to the longitudinal direction of the road, and the side end of the base member at the upper end of the main body. A guide member consisting of a cover portion extending in the longitudinal direction of the road extending toward the base member so as to cover the upper surface of the portion, and a fastening member connecting the side end portion of the base member and the cover portion of the guide member. Is provided.

The invention of claim 2 is to provide a safety fence above the road barricade for improving the function of the road barricade. Specifically, the invention of claim 1 is as follows. In addition to the above configuration, the base member has a safety fence holding portion that holds a safety fence that is provided so as to extend in the longitudinal direction of the road.

[0012]

According to the structure of the invention of claim 1, a base member having a weight that is hard to move on the installed road surface due to lateral pressure when a traveling vehicle comes into contact, and the base member provided on the side of the base member. Since the guide member is provided so as to be connectable and has a cover portion, main portions of the side portion and the upper portion of the base member are covered by the guide member.

Further, since the guide member has an inclined surface which has a slope that diverts the direction of the tire of the traveling vehicle contacting from the diagonal direction to the longitudinal direction of the road, the tire of the traveling vehicle contacts from the diagonal direction. However, when riding on the inclined surface, the lateral pressure on the inclined surface of the tire is dispersed into the horizontal component force and the vertical component force to reduce the riding force, so the running direction of the tire is the longitudinal direction of the road. Be converted to.

According to the configuration of the invention of claim 2, since the base member has the safety fence holding portion, the required safety fence is held by the safety fence holding portion so that the safety member is above the base member in the longitudinal direction of the road. It is provided so as to extend.
