Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boundary block on a road or the like, which can be used as a pedestrian road boundary or a curbstone, and a construction method thereof.

[0002]

2. Description of the Related Art Conventionally, in order to form a pedestrian road boundary or curb with a concrete block, a plurality of boundary blocks each having a length of about 60 cm are singly laid on a grounded and appropriately leveled construction surface. It was common to adjust the height with mortar and adjust the height exactly so that it fits along the boundary line, and then fill the joints that are about 1 cm wide. From a construction point of view, the conventional construction method of such a single block is inefficient, and from the viewpoint of strength, it is necessary to adopt a construction method in which each individual block is installed with a strong structure such as rolled concrete. There was a difficulty that I could not get. Therefore, recently, it has begun to be seen that the boundary block alone is used with a length of about 2 m. However, if the block itself becomes long like this,
Since it is a heavy object, it is difficult to install and is inferior in aesthetics.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a boundary block can be constructed more easily, efficiently, and safely than ever before, and as a result, the boundary block can be manufactured at low cost and is excellent in aesthetics. And its construction method.

[0004]

The present inventor has solved the above problems by
The length in the direction of the border is approximately 3 compared to the width in the direction perpendicular to the border.
We have developed a boundary block for roads, which is a long block up to 20 times longer and has height adjusting means at or near the bottom. When the length of the long block is 3 times the width or less, it is not applicable to increase the construction efficiency by lengthening the unit block, which is the object of the present invention,
If the length of the long block exceeds 20 times the width, the total length of the boundary block becomes too long, which is not preferable in manufacturing, construction, transportation, and the like. The width of the long block is 3
About twice as many are often used for adjustment during construction. The height adjusting means here is not a conventional gravel or adjusting mortar or wedge piece on the bottom surface of the block, but a female screw hole into which a vertical adjusting bolt mounted on the boundary block itself can be screwed, A bolt protruding from the block body and an adjusting block with a female screw screwed into it, or a flat bar longer than the width of the block is fixed to the lower surface of the block body if necessary for construction, and an adjusting bolt is provided on it. An angle member may be further used between the flat bar and the block body, or an angle may be used between the adjusting bolt and the block body. The height adjusting means is preferably provided on both sides in the width direction in the vicinity of the bottom in front of the boundary block in the construction progressing direction, but if it is required in design or construction, it is not denied that it is provided in the middle or rear. Absent.

In the vicinity of the height adjusting means, it is preferable to provide a safety streak such that a space is formed between the bottom surface of the boundary block or the vicinity of the bottom surface and the block mounting surface.

Further, the boundary block is provided with a positioning fitting means. The positioning / fitting means may have a structure capable of positioning the joint between the boundary blocks in the boundary line direction and the direction perpendicular to the boundary line by this, for example, by providing a pin or a protrusion on one boundary block of the mating partner, and joining. This is a structure in which a pin receiving hole or a projection receiving hole is provided on the other side of the partner. Taking a single boundary block as an example, a pin or a protrusion that projects downward from the front of the boundary block and is erected on the protruding portion is provided, and a notch is formed at the rear lower portion of the block by notching as much as the protruding portion fits. A structure in which a pin receiving hole or a projection receiving hole is provided upward from the portion is preferable.

[0007] boundary block of such a long, providing a concave groove joint shape which is of粧目locations.

Further, positioning marks for the butting are provided at the top ends of the front and rear ends.

The boundary block construction method as described above is
In installing the boundary block of the long butt sequentially end along the boundary direction, height adjustment means construction forward border established the boundary blocks so that the arrangement is installed in the previously It is characterized in that the boundary blocks and the boundary blocks to be installed later are sequentially installed along the boundary line direction while adjusting the level by the height adjusting means.

[0010] According to the present invention, when the boundary blocks placed above is adjusted by adjusting means to an appropriate height, it can be installed even then installed the boundary block and vertically adjusted to a predetermined position. Even if you accidentally fall during these operations, if a safety streak is provided on the bottom surface of the boundary block or near the bottom surface, there will be a gap between the bottom surface of the boundary block and the block mounting surface. It is possible to prevent accidents such as getting your feet caught, and it becomes an anchor bar after being embedded in concrete.

Since the boundary block of the present invention is provided with the convex portion at the end and the concave groove at the intermediate portion, it is installed by the conventional construction method having joints although it is a long product. It becomes a pedestrian road boundary or curb with the same appearance as.

Furthermore, by providing the positioning marks at the top ends of the front and rear ends, it is easy to align with the water thread at the time of construction and the positioning becomes very easy.

Since the method of constructing the boundary block is repeated installation of a long block, it is a highly efficient, accurate and safe construction method for completing construction in a short time even over a long distance.

As shown in these figures, the boundary block 1 is a long block whose length in the direction of the boundary line is about 11 times the width in the direction perpendicular to the boundary line, and the total length is 2.44 m, which is almost the same as the conventional product. It is four times as long. Height adjusting means 2, 2 are provided on both sides in the bottom width direction at one end in the longitudinal direction (forward in the construction proceeding direction). The height adjusting means 2 is a female screw hole 3 provided at the bottom of the boundary block and a vertical adjusting bolt 4 screwed into the female screw hole 3. It can be adjusted to an appropriate height by turning the vertical adjustment bolt 4. There is a U-shaped safety streak 5 between the two vertical adjustment bolts 4, 4, and even if it is accidentally dropped, a gap is created between it and the block mounting surface, so the human body does not get caught It has become.

A projecting step portion 6 is provided at a lower front portion of the boundary block 1, and a projecting pin 7 standing at the center of the projecting step portion 6 is provided. On the other hand, the lower rear part of this block is cut out so that the protruding step 6 is fitted therein, and a pin receiving hole 9 is provided upward from the lower surface of the cut step 8. These are the positioning and fitting means
