That is, the thing of this application is an assembly type median strip consisting of the separator main body 2 and the fixed hardware 3 which have the following conditions.

The separation strip main body 2 has an inclined surface 2B projecting upwardly having a substantially square cross section on the upper surface of the main body 2A, which is composed of a horizontally elongated prismatic body in the left-right direction, and a groove-like groove having a substantially square cross section on the lower surface. A recessed portion 2C is formed in the left-right direction, and artificial turf 2D is stretched on the upper surface of the separation strip main body, and a cushioning material 2E is attached to the upper edge of the front and rear surfaces of the separation strip main body.

Further, the fixed hardware 3 is attached to the upper end of the supporting leg 3A to be planted on the ground G, L, and the fixed plate 3B is attached to the upper end of the supporting leg 3A in a direction perpendicular to the vertical direction of the supporting leg.
are arranged in series, and the fixing plate 3B is connected to the groove-shaped recessed portion 2.
The front side has a substantially square shape corresponding to the cross-sectional shape of C, and on the front and rear sides of the fixed plate name B, there are receiving plates 3C that are to be in contact with the front and rear inner walls of the groove-shaped recessed part 2C.
are installed in succession.

In this case, connection mounting nuts 2I can be buried near the left and right ends of the separation strip main body 2.

Further, mounting holes 2F for the marker posts 4 can be vertically formed in the separator main body 2 as required.

Furthermore, substantially U-shaped drain ports 2K facing downward from the front can be provided at predetermined intervals on the lower surface of the separation strip main body 2.

(b) Examples of implementation of the idea Examples will be described with reference to the drawings.

Reference numeral 1 denotes an assembly type median strip consisting of a strip main body 2 and fixed hardware 3.

The separation strip main body 2 has a main body 2A formed of a rectangular prism body elongated in the left-right direction, and has an upwardly projecting inclined surface 2B having a substantially square cross section on the upper surface thereof, and a groove having a substantially square cross section on the lower surface. A shaped recess 2C is formed in the left-right direction, and artificial turf 2C is formed on the upper surface of the separation strip main body.
D is stretched, and a cushioning material 2E is attached to the upper edge of the front and rear surfaces of the separator main body.

In addition, the fixed hardware 3 is provided with a fixed plate 3B connected to the upper end of the supporting leg 3A to be planted on the ground G, L so that the supporting leg 3A has a direction orthogonal to the vertical direction of the supporting leg. 3B is the groove-like recessed portion 2C.
The fixed plate 3B has a substantially square shape from the front corresponding to the cross-sectional shape of the fixing plate 3B, and a receiving plate 3C that comes into contact with the front and rear inner walls of the groove-shaped recess 2C is stretched on the left and right sides of the fixing plate 3B.

Reference numeral 2E' denotes a lifting eye bolt which is detachably screwed onto the upper surface of the separator main body 2 at a predetermined interval.

2F is a mounting hole for a sign post 4 that is vertically opened in the separator body 2 as necessary, and 2G is a hole for installing a sign post 4.
A push bolt 2H is a cap that is pressed against the side wall of the separator main body 2.

Reference numeral 5 denotes a receiving pipe buried in advance at a desired location for attachment of the separation strip, and 5A is a rubber cap that is fitted into the receiving pipe when not in use, and is removed when in use.

2I is a connecting mounting nut attached to both ends of the separation strip body 2, and 2J is a band-shaped connecting fitting that connects the separation strip body 2 using this nut 2I.
A bolt hole 2J' corresponding to I is opened.

2K is a drain port provided at a predetermined interval on the lower surface of the separator main body 2.

6 is connected in a bent state as shown in Fig. 10,
It is a rubber plate that fits between the separation band bodies 2, and is configured to have a shape that matches the cross-sectional shape of the separation band body 2.

Reference numeral 7 designates a starting and ending point block, and a recess 7B for receiving the end of the separation strip body 2 is formed in the linear part of the block body 7A, which is approximately semicircular in plane, and the separation strip body 2 and block 7 are in a plane. L-shaped connecting fitting 7C
It is tightened using bolt 7D.

This block 7 has a striped pattern for traffic safety.

7E is the mounting hole for the sign post.

C Effect Explain along with the effects.

C. Effects of the invention Since the present invention is configured as described above, it produces the following effects.

B. The main body of the median strip can be installed in a straight line at the desired location on the road.

In this case, the separation strip main bodies 2 located at the front and back can be connected and integrated by the connecting fittings 2J.

In this case, since the fixed hardware 3 planted in the ground is configured to fit into the groove-like recess 2C of the separation strip main body 2, for example, when a traveling vehicle collides with the separation strip main body 2, Even if a pressing force is generated from the side, the separation strip main body 2 does not move.

(b) The desired work can be carried out by suspending the separator main body using eye bolts.

C. If necessary, a designated traffic safety sign board can be attached by planting a sign post in the mounting hole 2F.

(d) The concave part at the bottom conforms to the curved surface of the road surface and can maintain a secure installation condition.

E. During the snowy season, by performing the work in reverse to the above, the separation strip can be removed and stored outside the road until the snow melts the following year, thereby eliminating the inconvenience and drawbacks of the separation strip during the snowy season. It can be resolved.

In this case, the rubber cap 5A is fitted onto the receiving pipe 5.

F. Attachment hole 2F for the sign post 4 in the separation strip main body 2
In the case where the road is opened vertically, a sign post 4 can be installed to display various traffic signs.

G. If a large amount of melted snow water or rainwater occurs around the separation strip body 2 in the case where the lower surface of the separation strip body 2 is provided with approximately U-shaped water drainage ports 2K facing downward at predetermined intervals from the front, Since water flows from one side of the separation strip main body 2 to the other side through the water drain port 2K, it is possible to promote the drainage of snowmelt water and rainwater on the road surface.
