Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to curbs. More particularly, the present invention relates to curbs that can be replaced only partially, not entirely.
[0002]
[Prior art]
On the road, a curb is provided between the driveway and the sidewalk, which serves as a boundary between the two. On the other hand, in snowy areas, snow plows are used to remove snow, and frequent curb damages occur. After the thaw, the damaged curb is exposed and the landscape is spoiled.
[0003]
[Problems to be solved by the invention]
To replace a damaged curb, the entire curb must usually be replaced, but the weight of the curb itself is about 60 kg to 100 kg, making it difficult to replace the curb alone and performing multiple tasks. There is a problem that it takes time and labor because of the need for staff. Further, even if there is no damage to the lower part of the curb, there is another problem that the entire curb has to be replaced, which increases the cost.

BEST MODE FOR CARRYING OUT THE INVENTION
Next, a curb according to a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a curb according to the first embodiment of the present invention. A curb according to a first embodiment of the present invention, generally designated by the reference numeral 10 in FIG. 1, includes a lower body 12 that is partially embedded in the ground, An upper body 14 covers the entire upper surface, and a connecting means 16 for connecting the lower body 12 and the upper body 14 is provided.
[0014]
The lower body 12 has one side surface 12a which is inclined in a side view (usually located on the side of the road). In addition, the upper surface of the lower main body 12 has a step-like shape constituted by the first surface 12b and the second surface 12c located lower than the first surface 12b. In addition, the lower main body 12 is formed of concrete or mortar.
[0015]
The upper main body 14 has a shape that complements the lower main body 12. That is, the side surface 14 a of the upper body 14 on the same side as the side surface 12 a of the lower body 12 is inclined. The lower surface of the upper body 14 has a step-like shape that matches the step-like upper surface of the lower body 12 when the upper body 14 is arranged above the lower body 12. Further, the upper main body is provided with a slot hole 14d through which a connecting means 16 described later penetrates when the upper main body 14 is disposed above the lower main body 12. The upper body 14 is made of concrete or mortar.
[0016]
The connecting means 16 is an anchor bolt protruding vertically upward from the first surface 12b of the lower main body 12, and protrudes horizontally laterally from a location between the first surface 12b and the second surface 12c of the lower main body 12. An anchor bolt is provided, and a male screw is provided at a tip of the anchor bolt, and a nut is screwed to the male screw.
[0017]
In using the curb 10 configured as described above, first, as shown in FIG. 2A, the damaged upper body 14 is removed, and a new undamaged upper body 14 is placed on the lower body 12. The upper body 14 is mounted on the lower body 12 by screwing a nut to the anchor bolt 16 (see FIG. 2B) (see FIG. 2C).
[0018]
FIG. 3 is a side view showing the curb 20 according to the second embodiment of the present invention. The curb 20 has substantially the same configuration as the curb 10 except that a part of the upper surface of the lower main body is exposed. That is, the curb 20 includes a lower body 22 partially embedded in the ground, an upper body 24 disposed above the lower body 22 and covering a part of the upper surface of the lower body 22, a lower body 22 and an upper body 24. And a connecting means 26 for connecting.
[0019]
The present invention is not limited to the above embodiments of the invention, and various modifications can be made within the scope of the invention described in the claims, which are also included in the scope of the invention. Needless to say, it is.
[0020]
For example, in order to protect the upper surface of the lower main body, the upper surface of the lower main body 12 may be covered with an iron plate 18 as shown in FIG.
[0021]
Further, in the above embodiment, an anchor bolt embedded in the lower main body is used as a connecting means for connecting the upper main body and the lower main body. However, as shown in FIG. 30 may be embedded and connected by screwing a bolt 32 into the female threaded sleeve 30. Alternatively, as shown in FIG. 5, the upper body may be provided with a convex portion 34 and the lower body may be coupled by providing a concave portion 36 corresponding to a corresponding portion (in this case, a concave portion is provided in the upper main body, A projection may be provided on the lower body).
[0022]
Also, as shown in FIG. 6, a plate member 40 having a T-shaped cross section is embedded in the upper body, and a concave portion 42 in which the plate member 40 is inserted is provided in a corresponding portion of the lower body, so that the lower body has a horizontal direction. May be inserted by inserting a male threaded bolt 46 into the hole 44 extending into the hole and screwing it into the female threaded hole 40 a of the plate member 40.
[0023]
Further, an adhesive may be used as the connecting means.
[0024]
Further, in the above embodiment, the upper body is made of concrete or mortar, but the upper body may be made of a metal material such as steel or a ceramic material. Further, the upper body may be colored to make the scenery gorgeous.
[0025]
【The invention's effect】
According to the present invention, even when the upper surface of the curb is damaged, it is sufficient to replace only the upper main body of the curb without replacing the entire curb, so that the cost can be reduced. In addition, since only the upper body needs to be replaced, only one worker can perform the replacement.
