Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a concrete-side groove cover and a plug for closing a concrete-side groove cover handle.

[0002]

2. Description of the Related Art Reinforced concrete side groove covers for roads are JIS.
The standard stipulates that a notch for a handle should be provided. FIG. 10 is a plan view showing a state in which the concrete side groove cover is attached to the side groove.

[0003] As can be seen from Fig. 10, when the concrete-side groove cover 10 is laid, the notch portion 20 for a handle is in a perforated state.

[0004] In a low traffic area, this is not a problem, but in an urban area where there is a large number of traffic, the heel of a high heel can be inserted into the notch 20 for handholds, or a blind or elderly person can use the tip of a cane. Troubles, such as piercing the child or putting the foot into the infant.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems described in the prior art, and has a concrete side groove lid capable of closing a handle portion of a side groove lid without forming a step. It is an object of the present invention to provide a plug for closing a groove on the concrete side.

[0006]

A concrete-side groove cover according to the present invention is characterized in that a notch is provided above a handle of the concrete-side groove cover so that a plug can be mounted without forming a step. The plug for closing the concrete-side groove lid handle is formed by a flat top having a flat upper surface formed so as to be fitted into a gap formed between the notches of the concrete-side groove lid handle. ,
It is characterized in that a body portion formed so as to be able to close part or all of a gap formed between the hand hooks is integrally extended, and a hole is provided through the top portion and the body portion. The body may be removed if necessary.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. Is provided.

For example, FIG. 1 shows an L-shaped notch 3, FIG. 2 shows an arc-shaped notch 3, FIG. 3 shows a funnel-shaped notch 3, FIG. 4 shows a wedge-shaped notch 3, and FIG. In the example of the notch 3, if the notch 3 is shown in a plan view, FIG. 6 (a) when the shape of the clasp 2 is U-shaped, and FIG. 6 when the shape of the clasp 2 is trapezoidal.
(B).

Next, the plug A for closing the handle 2 of the concrete-side groove cover 1 is provided with the handle 2 of the concrete-side groove cover 1.
A top part 4 formed so as to be fittable into a gap part a formed between the notches 3 of the flat top part 4 and a body part formed so as to be able to close part or all of a gap b formed between the clasps 2. 5 is integrally extended, and a hole 6 penetrating the top portion 4 and the body portion 5 is provided.

When the notch 3 provided above the handle 2 of the concrete-side groove lid 1 is as shown in FIGS. 4 and 5, the body 5 may be removed.

The plug A is made of rubber, plastic or the like, and the top 4 and the body 5 are formed with the gaps a,
b, is slightly thicker than b, and is formed into a shape that can be fitted slightly tightly in the gaps a and b. When it is mounted in the gaps a and b of the concrete-side groove lid 1, the upper surface of the flat top 4 is formed. Is formed to be substantially the same level as the upper surface of the concrete-side groove cover 1 so that no step is formed.

The shape of the plug A is determined by the shape of the gaps a and b, and is formed into a shape as shown in FIGS. 1 to 5, for example.

The hole 6 passing through the top 4 and the body 5 allows rainwater or the like to flow therein. The shape of the hole 6 is not particularly limited, and matches the environment such as a circle, a rectangle, a star, and a triangle. Thus, it can be appropriately selected.

At the time of implementation, the plug A is composed of the top 4 and the trunk 5
7A, the top part 4 and the body part 5 of the plug A are inserted into the gaps a and b of the concrete-side groove cover 1 and mounted as shown in FIG. When the plug A does not have the body 5, the top 4 of the plug A is inserted into the gap a of the concrete-side groove cover 1 and mounted as shown in FIG. Since the top 4 of the plug A is fitted and locked in the notch 3 of the handle 2 of the concrete-side groove lid 1, even if the plug A is stepped on from above, it does not fall.

When the concrete side groove cover 1 is removed by cleaning the side groove, for example, when the hole 6 of the plug A is rectangular, a hook 7 is attached to the tip as shown in FIG. Using the provided jig 8, insert the hook 7 in parallel with the rectangular hole 6, then twist it so as to be orthogonal to the hole 6, and lock the hook 7 on the bottom of the plug A. When the jig 8 is pulled up, it can be easily removed.

[0016]

Since the present invention is configured as described above, it has the following effects. Since the notch on the concrete-side groove lid is notched, the plug can be attached without forming a step. It is possible to prevent the heel of the high heel from being pushed into the notch for the handle of the concrete-side groove cover. It is possible to prevent a blind man or an elderly man from sticking the cane tip into the handle notch of the concrete-side groove cover. It is possible to prevent a problem in which an infant fits a foot into a notch for a handle of a concrete-side groove cover. Since the main body is provided with a through hole, drainage of rainwater or the like can be performed.
