Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign (correctly, a sign) fixedly attached to a road surface, and more particularly to a block-shaped road sign body.

[0002]

2. Description of the Related Art There are two types of road markings, a two-dimensional one drawn with paint or the like, and a three-dimensional one to which a block-shaped member is fixed. The present invention is directed to a technique for fixing a block-shaped member, that is, a member whose thickness can be clearly recognized with the naked eye, to a road surface. FIG. 5 is shown for explaining a mounting structure and a mounting method of a block-shaped road marking body according to the prior art, and (A) is a schematic diagram illustrating a preparatory step for mounting the block-shaped road marking body on the road surface. Is a vertical cross-sectional view, and FIG. 6B is a vertical cross-sectional view in a state where it is also attached to a road surface. As shown in (A), anchor bolts 9 are fixed to the lower surface of the concrete block 8 so as to project. A block mounting hole 11 is formed in the road surface 10 so as to correspond to the anchor bolt 9. Then, an adhesive is applied to the area 12 facing the bottom surface of the block 8, and the adhesive is injected and filled in the block mounting hole 11. From the state of the above (A) figure, the concrete block 8 is pressed toward the road surface 10 and adhered as shown in the (B) figure.

[0003]

When the concrete block 8 is adhered to the road surface 10 as shown in FIG. 5B, it is firmly attached and cannot be easily removed. However, in practice in road construction and management, it is often necessary to move block-shaped road markings. For example, when constructing a road with two lanes on each side (four lanes on each side), two lanes are made as the first stage construction, and a block-shaped road marking body is arranged in the center of the lane to construct a median strip. Next, as the second phase of construction, a road with two lanes will be lined up with the above two lanes to make a total of four lanes, and the block-shaped road markings that previously constituted the median strip will be moved to the four-lane road. To complete. However, since the concrete block 8 attached as shown in FIG. 5 (B) according to the related art cannot be removed from the road surface 10, the pavement layer is cut along the periphery of the concrete block 8 to remove the scratches. Must be repaired,
It wasted a great deal of time and labor and increased road construction costs. Further, the concrete block removed in this way was largely damaged and could hardly be reused. Furthermore, the weight of one concrete block is 30 Kg, which is very heavy, and the transportation cost is high, and the labor for installing and transporting the concrete block is large and dangerous. Further, the concrete block of the conventional example shown in FIG. 5 is apt to be cracked, and there is a problem that fatal damage is given to the concrete block when the water infiltrated into the crack is frozen. The present invention has been made in view of the above circumstances, is lightweight and easy to handle, can be firmly attached to a road surface, and can be quickly and easily attached and detached, and can be reused or reused after being detached. The present invention aims to provide a method of attaching a block-shaped road marking body and a method of attaching the same, and at the same time, to provide a technique for preventing damage due to cracking.

[0004]

In order to achieve the above object (quick and easy attachment / detachment), a method of attaching a block-shaped road marking according to the present invention is a method of attaching a block-shaped road marking to a road surface. An anchor having a hole is partially embedded in and fixed to the road surface with the female screw hole exposed on the road surface, and a bolt is inserted into the block body of the block-shaped road marking body, and the bolt is inserted into the female thread of the anchor. It is characterized by being screwed into the hole and tightened.

Not only is a sleeve that carries the tightening force of the bolt provided, but if this is insert-molded in a synthetic resin material, the sleeve is wrapped in the synthetic resin, so if metal such as iron or aluminum is used, the rust prevention effect There is. Also,
When a metal such as stainless steel that is relatively resistant to rust is used, the surface contacting the bolt may be exposed without wrapping it in resin. This sleeve is not limited to metal, but may be any one that has the required strength. Further, by providing a concave portion or a convex portion along the outer periphery near the outer periphery of the center of the sleeve, the sleeve and the synthetic resin block main body are completely fixed and integrated, so that the mounting state becomes strong. Moreover, there is no risk of losing the sleeve when attaching or detaching. In order to attach the block main body with a bolt, a through hole (bolt hole) for inserting a bolt must be provided in the block main body, and a bolt-like recess is provided in an upper opening of the through hole. When the head is stored, it is convenient because the bolt head does not protrude from the top surface of the block body. Furthermore, if a cap is attached to the upper opening of the counterbore-shaped concave portion and sealed, it is possible to prevent the intrusion of dust, dust and the like. A technique of installing a light bulb on a road surface sign to emit light is known, but when attaching this kind of road surface sign to the road surface, electric wiring work is involved. There is no particular problem in using electric wiring work together with the installation of the road marking according to the present invention, but when the electric wiring work is also performed, the features of the present invention are "quick and easy" and "no road surface damage". The effect will not be exerted. In such a case, a solar panel and L
By providing the ED light emitting body and the battery, electric wiring work is unnecessary, and the effect of the method of the present invention that "the road surface is not destroyed and can be quickly and easily attached" is exhibited without being hindered.

Further, since the block-shaped road marking body mounting structure according to the present invention has all of the constitutions that are indispensable for carrying out the mounting method described above, it is possible to carry out the mounting method. It is suitable.
