Description

TECHNICAL FIELD The present invention relates to a gutter cover plate for closing an upper surface of a gutter that is constructed on a side edge of a road or the like.

2. Description of the Related Art A conventional gutter cover plate F is a rectangular concrete plate having the same width as the U-shaped groove U to be applied (FIG. 7).
At the center of both short sides, a trapezoidal recess F1,
F1 is formed. Therefore, after the construction, a flat hexagonal hole formed by combining the concave portions F1 and F1 can be opened at the boundary between the adjacent cover plates F and F. Also,
This hole not only serves as a handle for rolling up the cover plate F, but also allows rainwater on the upper surface of the cover plate F to flow efficiently into the U-shaped groove U.

However, since such a lid plate has a large hole formed in the boundary between two adjacent sheets, footwear of a walking woman or child may fall into the hole, sometimes causing unexpected injury. Foreign substances such as dust and fallen leaves easily enter the U-shaped groove, which may cause the U-shaped groove to be clogged.

Therefore, a lid plate composed of an upper plate made of a water-permeable material and a lower plate of appropriate strength has been proposed (Shokaisho 6).
2-103887). In this product, since the upper plate is water permeable, rainwater on the upper plate can permeate to the lower plate side through the upper plate, and flow down into the U-shaped premises through the drain holes provided in the lower plate. You can That is, it is not necessary to open a dangerous drainage hole on the upper surface of the upper plate.

Problems to be Solved by the Invention According to such conventional technology, since the upper plate made of a water-permeable material has low strength and is brittle, it is not uncommon for the upper plate to be damaged during construction or maintenance. There was a problem.

Therefore, in view of the problems of the prior art, the purpose of the present invention is to ensure safety for pedestrians by providing a locking hole that is opened to a necessary minimum on the upper surface side of the upper plate,
Moreover, it is an object of the present invention to provide a gutter cover plate that is easy to handle and has a very low risk of damaging the upper plate during construction or the like.

Means for Solving the Problems The structure of the present invention for achieving the above object includes an upper plate made of a water-permeable material and a lower plate having a predetermined strength and capable of draining water from the upper surface side to the lower surface side. The upper plate is formed with a hooking hole for lifting, and this hooking hole allows the lower end of the inverted T-shaped hook bar to be inserted and rotated.
The gist is to form a combination of the long hole and the spot facing on the lower surface side.

In addition, a drain hole is formed in the lower plate, and the upper surface of the lower plate is
A recess for guiding water can be formed in the drain hole.

Further, the upper plate and the lower plate can be formed separately or integrally.

With this structure of the invention, since the upper plate is made of a water-permeable material, rainwater on the upper surface of the upper plate penetrates into the upper plate, permeates the upper plate, and reaches the upper surface of the lower plate. Through the U-shaped groove. Therefore, it is not necessary to open a hole for letting rainwater flow down to the U-shaped groove on the upper surface of the upper plate, and therefore, the locking hole for lifting can be kept to a necessary minimum size. .

Further, by forming the recessed portion on the upper surface of the lower plate, the rainwater that has reached the lower plate can be guided to the drain hole more efficiently and flow down to the U-shaped groove.

If the upper plate and the lower plate are formed separately, each can be handled individually, so the weight of the handling unit can be lightened, and if both are formed integrally, the lower plate can be used as a whole. Since the strength can be increased, the risk of damaging the upper plate during construction can be further reduced.

Example Hereinafter, an example will be described with reference to the drawings.

The gutter cover plate is a combination of an upper plate 11 and a lower plate 12 (FIG. 1).

The upper plate 11 is a rectangular plate made of a water permeable concrete known by a trade name such as Toyocon (Toyo Denka Kogyo Co., Ltd.) or Polacon (Ozawa Concrete Co., Ltd.), or a water permeable material such as porous ceramics. The lifting lock hole 11a is formed in the center of the lock hole.

The locking hole 11a is formed by combining a long hole 11c with a round hole 11b and a circular counterbore 11d on the lower surface side of the upper plate 11 (FIGS. 2 and 3). 11c is formed so as to penetrate from the upper surface of the upper plate 11 to the top surface 11e of the spot facing 11d. The width W of the upper plate 11 is adapted to the opening width d of the U-shaped groove U used (fourth).
Figure). Further, the length L may be set appropriately (FIG. 1).

The lower plate 12 is a plate body having the same size as the upper plate 11, and draining holes 12a, 12a ... Penetrating from the upper surface to the lower surface are formed at appropriate places on the upper surface thereof, while the upper portion is A locking hole 12b having substantially the same shape as the locking hole 11a of the plate 11 is formed. However, a circular spot facing is not necessarily provided on the lower surface side of the locking hole 12b.

Now, after covering the U-shaped groove U with the lower plate 12,
When the upper plate 11 is overlaid on the upper surface of the lower plate 12, the upper surface of the U-shaped groove U can be completely closed (Fig. 4). At this time, since only a small locking hole 11a is opened on the upper surface of the upper plate 11, there is no possibility that a pedestrian walking on the upper plate 11 will be in a dangerous situation. Further, since the upper plate 11 is made of a water permeable material, rainwater on the upper plate 11 quickly permeates the upper plate 11 and permeates to the upper surface of the lower plate 12. Therefore, this rainwater can flow down to the U-shaped groove U via the water drain holes 12a, 12a ... Of the lower plate 12. The upper plate 11 made of a water-permeable material serves as a filter and prevents dust, defoliation, etc. from entering the U-shaped groove U.

When the upper plate 11 is rolled up, a dedicated inverted T-shaped hook bar H is used (Fig. 3). A hook H1 is formed at the lower end of the hook rod H, and a lifting ring H2 is formed at the upper end.

Now, assuming that the hook H1 is sufficiently longer than the diameter of the round hole 11b of the locking hole 11a and slightly shorter than the length of the long hole 11c, the lower end portion of the hook rod H is formed so that the hook H1 is longer than the long hole 11b.
It can be inserted into the locking hole 11a as if it were inserted into c. Therefore, the hook H1 is the top surface 1 of the spot facing 11d.
When it is deeply inserted until it exceeds 1e, the hook bar 11
Is rotated horizontally, the hook H1 becomes
Since it can be engaged with the upper plate 1 from below, by pulling the hook rod H upward in this state, the upper plate 1
1 can be rolled up by lifting it up.

After the upper plate 11 is lifted and removed in this way,
Insert the hook bar H into the locking hole 12b, and in the same way,
The lower plate 12 can also be lifted.

Other Embodiments A recess 12c is provided on the upper surface of the lower plate 12 in order to effectively guide rainwater passing through the upper plate 11 to the drain holes 12a, 12a.
Can be formed (FIG. 5). The shape of the concave portion 12c may be arbitrarily determined as long as it is suitable for the purpose, and may be, for example, a shallow bowl shape that is inclined low toward the drainage hole 12a, or a groove shape, in addition to the simple flat plate shape. I shall. Further, the planar shape thereof is not limited to the circular shape and may be arbitrarily determined.

The upper plate 11 and the lower plate 12 can be formed separately from each other as in the previous embodiment and can be overlapped at the time of use, but instead, both are integrally formed from the beginning. You can also At this time, the upper plate 11 and the lower plate 12 that are independently molded may be cemented with mortar or other suitable material, although they may be integrally molded so that only the upper portion of one lid plate is water-permeable. It is also possible to form a laminated structure via a different adhesive. In the case of the former, the locking holes 11a, 12
b is one locking hole 11a penetrating from the upper surface to the lower surface.
In the latter case, the upper plate 11
The engaging holes 11a and 12b of the lower plate 12 and the lower plate 12 may be formed at the same place, and one continuous engaging hole 11a may be formed by bonding.

In this embodiment, since the hook bar H can be inserted into the lower surface of the lid plate without fail, the locking hole 11a is formed.
The spot facing 11d is not always necessary.

The side edges of the upper plate 11 and the lower plate 12 on the long sides may be tapered downward in accordance with the shape of the U-shaped groove U to be combined (FIG. 6).

Further, the locking hole 12b of the lower plate 12 is formed by the drain holes 12a, 1
If it can be lifted upward by using 2a ..., this can be omitted. Furthermore, the drain hole 1
The shapes of 2a, 12a, ... May be any shape other than circular regardless of the presence or absence of the locking hole 12b. As an extreme example of this, a member having a lattice structure such as grating, The lower plate 12 may be one that can drain water freely from the upper surface side to the lower surface side and has a predetermined strength.

As described above, according to the present invention, the upper plate made of the water-permeable material and the lower plate holding the upper plate are combined, and the upper plate is adapted to the inverted T-shaped hook bar. By forming a locking hole for the upper plate, only the minimum required small locking hole is opened on the upper surface of the upper plate, so there is no danger of pedestrians being injured. By doing so, there is an excellent effect that it is easy to handle and there is very little risk of damaging the upper plate even during construction.

Also, since the locking hole is accompanied by a spot facing on the lower surface side, the upper plate is
Even when they are stacked in close contact with the lower plate or another upper plate, they can be hoisted in order from the upper one without any trouble via the hook bar, which is also very convenient in handling.
