Description

  The present invention relates to a detachable curb block used for a concrete block or the like.

  Conventionally, as shown in FIG. 1, the curbstone 21 and the concrete block 22 are integrated.

As shown in FIG. 2, between the roadway 31 and the vacant land 33, a concrete block 22 and a sidewalk 32 in which the curb 21 is integrated are provided.
When a building or the like is constructed in the vacant land 33, the car 34 enters and leaves the roadway 31 and the vacant land 33, so the curb 21 must be removed.
However, removing the curbstone 21 has the following drawbacks.
1: Since the curbstone 21 and the concrete block 22 are integrated, in order to cut the curbstone 21 from the concrete block 22 or to crush the curbstone 21, a large-scale device such as a cutter or a crusher must be prepared.
2: Since a large-scale device such as a cutter or a crusher must be prepared, the roadway 31 and the sidewalk 32 are closed on one side or the entire surface, which causes problems such as traffic congestion and traffic safety.
In order to solve these drawbacks, a curb block 1 that can be attached to and detached from the concrete block 11 as shown in FIG. 3 has been devised.

First, claim 1 will be described.
(A) Two or more rectangular parallelepiped-shaped foot portions 3 that are integrated with the curb block 1 are provided on the bottom 2 of the curb block-shaped curb block 1.
(B) A hole 5 is provided from the top surface 4 of the rectangular parallelepiped curb block 1 to the center of the bottom 7 of the rectangular parallelepiped foot 3.
(C) An internal thread portion 6 is provided inside the hole 5.
This invention is the curb block 1 which can be attached or detached to the concrete block 11 comprised as mentioned above.

Next, claim 2 will be described.
(H) Two or more holes 15 are provided on the upper surface 14 having a rectangular shape.
(I) The position where the hole 15 is provided is on a straight line along the drainage channel 13 in the longitudinal direction of the upper surface 14 having a rectangular shape.
(Nu) An internal thread portion 16 is provided inside the hole 15.
A concrete block 11 to which the curb block 1 according to claim 1 can be attached.

The following effects are produced by the present invention.
1: Since the curb block 1 and the concrete block 11 are fixed by the bolts 18, in order to remove the curb block 1 from the concrete block 11, the bolts 18 are loosened and removed.
For this reason, it is not necessary to prepare a large-scale device such as a cutter or a crusher, and construction costs can be reduced.
2: Since the curb block 1 can be removed from the concrete block 11 by loosening the bolt 18 and removing it, the working time can be greatly shortened compared to when using large equipment such as cutters and crushers. , Construction costs can be reduced.
3: Since no large-scale equipment such as cutters and crushers are prepared, the working time can be greatly shortened, so that the time for blocking one side or the entire side of the roadway 31 and the sidewalk 32 can be greatly shortened. Problems such as these will be minor.
4: Since the curb block 1 and the concrete block 11 are separated, it is not necessary to worry about the protrusion of the concrete block 11 due to the curb 21 as compared with the case of being integrated with the conventional one. It is stable and easy to carry.
5: When the curb block 1 and the concrete block 11 are fixed with the bolts 18, since there is a rectangular parallelepiped foot 3, a gap 41 is generated between the curb block 1 and the concrete block 11. (Fig. 5)
This gap 41 serves as a drainage of rainwater that accumulates on the sidewalk 32.
For this reason, when the conventional curbstone 21 and the concrete block 22 are united, the drain port (not shown) provided in the lower center part of the curbstone 21 becomes unnecessary.
6: The present invention leaves the gap formed between the curbstone 21a and the curbstone 21b, which is performed after being embedded when the conventional curbstone 21 and the concrete block 22 are integrated. For this reason, no joint processing is performed, so that construction costs can be reduced.

Next, the best mode for carrying out the present invention will be described.
First, in claim 1,
A description will be given of providing two or more rectangular parallelepiped-shaped foot portions 3 integrated with the curb block 1 on the bottom 2 of the curb block 1 having the rectangular parallelepiped shape (a).
This is because when the foot 3 is provided at the bottom 2 of the curb block 1, the stability with the upper surface 14 of the concrete block 11 is increased as compared with the case where the foot 3 is not provided.
When two rectangular parallelepiped legs 3 are provided, it is preferable that the base 2 be close to both ends in the longitudinal direction.
In the case where three rectangular parallelepiped feet 3 are provided, a location near the both ends of the bottom 2 in the longitudinal direction and a center of the bottom 2 are preferable.
The shape of the foot 3 is generally a rectangular parallelepiped shape, but may be a polygonal shape other than the rectangular parallelepiped shape, a cylindrical shape, or an elliptical shape depending on the shape and application of the concrete block 11.

  Although the rectangular parallelepiped foot 3 is provided, it is preferable to manufacture the rectangular parallelepiped foot 3 integrally with the curb block 1 from the viewpoint of strength.

  There is also a method using an adhesive. In this method, the curb block 1 and the rectangular parallelepiped foot 3 are manufactured separately and attached with an adhesive. This is not preferable from the viewpoint of strength.

Next, when a hole 5 leading from the upper surface 4 of the rectangular parallelepiped-shaped curb block 1 to the center of the bottom 7 of the rectangular parallelepiped foot 3 is provided, a female screw portion 6 is provided inside the hole 5 of (c). This will be explained.
The present invention uses bolts 18 as a method for attaching and removing the curb block 1 to and from the concrete block 11.
The reason is to obtain the convenience of attaching / detaching and the strength of the connection between the curb block 1 and the concrete block 11.
There is also a method of using an adhesive for bonding the curb block 1 and the concrete block 11, but it is not preferable from the viewpoint of strength that it takes time to remove the adhesive.

Next, in claim 2,
A description will be given of providing two or more holes 15 in the upper surface 14 having the quadrilateral shape of (H).
Claim 2 is a concrete block 11 to which the curb block 1 of claim 1 is attached. Therefore, of course, if two holes are provided in the curb block 1, it is also necessary to provide two holes 15 in the concrete block 11. If three holes are provided in the curb block 1, three holes 15 in the concrete block 11 must be provided.

The position where the hole 15 is provided is described as being on a straight line along the drainage channel 13 in the longitudinal direction of the upper surface 14 having a rectangular shape.
Although there are various shapes of the concrete block 11, a rectangular parallelepiped shape is common, and the upper surface 14 has a quadrangular shape. When the concrete block 11 is embedded in the road, the curb block 1 is provided on the side of the sidewalk 32 on the upper surface 14 of the concrete block 11 as shown in FIGS. The installation position is on a straight line along the drainage channel 13 in the longitudinal direction of the upper surface 14. In short, the position corresponds to the hole 5 of the curb block 1.
However, some concrete blocks 11 are provided with slits (not shown) along the drainage channels 13 in the longitudinal direction of the upper surface 14, so that the curb blocks 1 can be easily installed avoiding the slits. Hole 15 will be provided.

The provision of the female screw portion 16 inside the hole 15 of (nu) will be described.
Since the concrete block 11 of the present invention is for mounting the curb block 1 of claim 1, a hole 15 is provided at a position corresponding to the hole 5, and a female screw part 16 is provided inside the hole 15.

These are side surface sectional views of the concrete block 22 with which the curb 21 is united. These are top views which show that the curbstone 21 and the concrete block 22 are embed | buried in the road. These are front sectional drawing of the curb block 1 of Claim 1. FIG. These are side surface sectional views which are going to attach the curb block 1 of Claim 1 to the concrete block 11 of Claim 2. FIG. These are the front views which attached the curb block 1 of Claim 1 to the concrete block 11 of Claim 2. FIG. These are the top views which show that the curb block 1 of Claim 1 and the concrete block 11 of Claim 2 are embed | buried in the road, and what removed the curb block 1 is the center concrete block 11.
