Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pedestrian and roadway boundary block which has a parking prohibition display integrated therein in advance.

On roads where the sidewalk and roadway are separated, a pedestrian and roadway boundary block is installed at the boundary between the sidewalk and the continuous roadway with a predetermined step, and a traffic barrier is installed at the top of the boundary block in a predetermined area. One of the signs has a sign prohibiting parking.

Conventionally, when placing a parking prohibition sign on the above-mentioned boundary block, a pedestrian and roadway boundary block of the specified dimensions stipulated in the Japanese Industrial Standards is laid in advance at the step between the above-mentioned sidewalk and roadway, and road construction is carried out. After the pronk was completed, the competent authority used a pickpocket to apply a strip of yellow paint to the top of the pronk in a predetermined width.

Markings made with paint or other materials are prone to uneven coating and bending of the long side of the strip, and begin to peel off within a few months, which not only significantly impairs the aesthetic appearance of the road, but also causes flaking. Currently, it is necessary to repaint each time, resulting in a large amount of maintenance costs.

In view of the above-mentioned problems, the present invention provides a pedestrian/vehicle boundary block that does not impair the aesthetic appearance of the road and does not require maintenance costs such as repainting. The reason is that a yellow plate-like part made of yellow concrete or yellow resin is integrally provided in advance.

Preferred embodiments of the present invention will be described below with reference to the drawings. 1st
The figure shows a first embodiment of the present invention, and numeral 1 in the figure is a pedestrian/vehicle road boundary block according to the present invention.

The pedestrian/vehicle boundary block 1 is a standard block having a substantially rectangular cross section and a predetermined length, and consists of a block main body 2 made of ordinary concrete and a yellow plate-like portion 3 integrally provided at the top of the block main body 2.

The yellow plate-shaped part 3 is a concrete plate formed in the shape of a plate with a thickness of about 10 m, and is made of white cement, in which highly wear-resistant white sand such as crushed sand is used as aggregate. The overall color was made yellow by using iron oxide as a yellow pigment.

Therefore, in manufacturing the concrete block 1 of this embodiment, the first method is to mix the above-mentioned white cement, aggregate, pigment, and water in a predetermined amount, and then form the above-mentioned plate-like material in a predetermined formwork. A yellow plate-shaped part 3, which has been poured and formed in advance, is installed at the bottom of a formwork corresponding to the shape of the boundary block 1, and ordinary concrete is placed on the yellow plate so that this bottom becomes the top of the boundary block 1. There is a method in which the mold is cast integrally onto the shaped part 3, cured, and then removed from the mold.

In addition, as a second method, a pair of weir plates are installed in advance at the bottom of the main frame corresponding to the shape of the above-mentioned boundary block l at an interval corresponding to the width of the yellow plate-like part 3. A method of casting yellow concrete for the yellow plate-like part 3 between the weir plates to a predetermined thickness, removing the weir plate after it has hardened to a certain extent, and casting ordinary concrete over it and allowing it to harden.9. There is.

Next, FIG. 2 shows a second embodiment of the present invention, in which the yellow plate-like portion 3 is provided over the entire top portion 2a of the block body 2.

When forming the boundary block 1 of this embodiment, the above t1
1. x The yellow plate-shaped part 3, which has been cast and hardened in the form of a plate in advance according to the molding method of the embodiment, may be installed at the bottom of the form, and ordinary concrete may be poured on top of it to form the yellow plate-shaped part 3 in one piece. Another method is to first pour yellow concrete for the yellow plate-shaped part 3 to a specified thickness at the bottom of the formwork of the concrete block 1, and then pour ordinary concrete and pour it in two layers to make it easier to use as one piece. It has the advantage of being able to be molded efficiently.

However, the first embodiment or the second embodiment molded as described above
If the pedestrian and roadway boundary blocks 1 of the embodiment are installed along the boundary 6 between the sidewalk 4 and the roadway 5 with the bottom part 1a buried in the ground by a predetermined depth as shown in FIG. 3, each boundary block l
The yellow plate-shaped portion 3 continues in the long side direction to form a strip-shaped parking prohibition display.

In addition, in the case of a parking prohibition display in which yellow stripes are arranged intermittently at predetermined intervals, boundary blocks 1 according to the first or second embodiment described above and normal boundary blocks without any display are laid out alternately. Just keep doing it.

In addition, in the above-mentioned embodiment, the yellow plate-shaped part 3 is formed of yellow concrete, but it is also possible to form the yellow plate-shaped part 3 into a plate of a yellow-colored synthetic resin that has high wear resistance and weather resistance. It is also possible to manufacture a pedestrian and roadway boundary block by embedding it in the block body 2.

In this case, the yellow plate-like part 3 made of KFi resin and the block body 2
In order to prevent peeling from the concrete, it is desirable to form convex portions 3a or 3b on both sides and the bottom of the yellow plate-like portion 3 for fixation to the concrete, as shown in FIG.

In the present invention configured as described above, since the yellow plate-shaped portion is already provided integrally on the top of the block body, the zone of the no-parking display and no-parking display can be changed just by installing the boundary block. Since it can be formed, there is no need for the troublesome painting process required in the past, which can save labor in construction work.

In addition, since the yellow plate-like part can be formed in advance to a uniform width, the yellow display band becomes a clear straight line, which is good-looking and does not spoil the aesthetic appearance of the road. Furthermore, the yellow plate-like part is wear-resistant. The system is made of a highly durable material, and since the entire interior is yellow, there is no need to worry about the yellow band peeling off even if there is some wear, and once installed, there is no need for maintenance costs. It has useful effects such as being extremely economical.
