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, the H-section steel is installed on the road surface so that the web is horizontal, and the fence is fixed to the horizontal web of the H-section steel by welding so as to stand upright from the web. Road barricades are 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 the appearance of the upper street is improved. There is the problem of not doing so.

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.
The problem is that even if the vehicle comes into contact with the vehicle from an oblique direction, the tire of the traveling vehicle that comes into contact with the vehicle may pass over the H-shaped steel and the vehicle may jump to the opposite side of the road barricade. There is a point.

Further, since the road barricade using the H-shaped steel as described above has a poor appearance and a large weight, the work of installing it on the road surface or the work of disassembling it is also a big accident, which also causes personal injury. It is unavoidable that the cost will increase with the risk of occurrence of.

In view of the above, the present invention has an assembly structure that can be easily installed, disassembled, or transported on a road surface, and prevents 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 inventions of claims 1 and 2 alleviate the impact when the tire of the traveling vehicle comes into contact with the tire from an oblique direction, and change the direction of the tire. The road barricade is provided with an inclined portion having a slope for turning in the longitudinal direction of the road, and the road barricade has a aesthetically pleasing portion including a bottom portion on which a weight can be placed and a portion other than the portion. By adopting a separable structure, it is easy to carry, assemble, install and dismantle and remove.

[0009] Specifically, the means for solving the problems of the invention of claim 1 is to provide a bottom portion extending in the longitudinal direction of the road, which is installed on the road surface and on which a weight can be placed, and a side end portion of the bottom portion in the longitudinal direction of the road. A lower base member consisting of a rising portion extending upward in the longitudinal direction of the road, and an inclined surface having a slope for diverting the direction of the tire of the traveling vehicle contacting in an oblique direction to the longitudinal direction of the road. Direction, a plate-shaped main body portion, an upper base member having a safety fence holding portion that is provided at an upper end of the main body portion and holds a safety fence that extends in the longitudinal direction of the road; a rising portion of the lower base member; And a fastening member that connects the main body of the upper base member.

Further, the means for solving the problems of the invention of claim 2 is to provide a bottom portion which is installed on the road surface and extends in the longitudinal direction of the road on which a weight can be placed, and a side end portion of the bottom portion in the longitudinal direction of the road. A base member having an inclined portion having an inclination for turning the direction of a tire of a traveling vehicle that extends and contacts in a diagonal direction to a road longitudinal direction, and is mounted on the upper surface of the bottom portion of the base member to the base member. And a guard member having a safety fence holding portion that holds a safety fence that is held and extends in the longitudinal direction of the road.

[0011]

According to the structure of the invention of claim 1, when the tire of the traveling vehicle provided on the road barricade comes into contact with the tire from an oblique direction, the inclined portion having a slope for turning the direction of the tire in the longitudinal direction of the road is provided. Since the tire is mounted on the plate-shaped main body of the upper base member that is connected to the lower base member that can be fixed on the road surface, when the tire of the traveling vehicle comes into contact with the vehicle diagonally and climbs onto the inclined portion, the tire The lateral pressure applied to the inclined portion is dispersed into a horizontal component force and a vertical component force, so that the riding force is reduced. As a result, the running direction of the tire is changed to the longitudinal direction of the road.

Further, since the upper base member is provided above the lower base member and the upper base member and the lower base member are connected by a fastening member, the upper base member and the base member are required. Sometimes it can be assembled or disassembled and separated.

According to the configuration of the invention of claim 2, when the tire of the traveling vehicle provided on the road barricade comes into contact with the tire from an oblique direction, the inclined portion having a slope for turning the direction of the tire in the longitudinal direction of the road is provided. Since it is provided on the base member that can be fixed on the road surface, when the tire of the traveling vehicle comes into contact with the vehicle from an oblique direction and rides on the inclined section, the lateral pressure applied to the inclined section by the tire is perpendicular to horizontal component force. The riding force is diminished by being distributed to the component force.
As a result, the running direction of the tire is changed to the longitudinal direction of the road.

Further, since the base member has the guard member mounted on the upper surface of the bottom thereof and holds the guard member,
The base member and the guard member can be easily assembled or disassembled and separated as needed.
