Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a cover for a drain installed on a floor that requires drainage, such as on a sidewalk, poolside, or in a kitchen.

[Conventional technology]

Drains and squares located on sidewalks, poolsides, kitchens, etc. are equipped with covers (hereinafter referred to as drain covers) to prevent danger and other reasons. This drain cover must have good water permeability and must have sufficient strength so that it will not be damaged even if pedestrians or others ride on it.

For the above reasons, conventional drain covers are
Metal bars are arranged in parallel or in a lattice shape at regular intervals and fixed together to form a plate (lid).

[The problem that the idea attempts to solve]

The above-mentioned conventional drainage ditch cover has extremely good water permeability because the bars are arranged side by side at intervals. Also, since it has a structure in which bars are arranged side by side, it has a so-called rib structure, which ensures strength to a certain extent. However, when a person stands on the lid, it is the same as standing on a rib, and depending on the footwear, walking on the lid is extremely inconvenient. Another disadvantage was that when an object was dropped, it would pass through the lid and fall into the groove. Furthermore, there is a drawback that the drain is clogged due to falling debris, which is difficult to clean.

An object of the present invention is to provide a drain drain cover which is even stronger, allows walking on the cover extremely smoothly after the cover is closed, and has a structure that prevents debris from falling.

[Means to solve the problem]

The drainage ditch cover of the present invention has a thin dish-shaped floor material receptacle on the surface of the main body, which has the same or similar structure as the conventional cover, and has a large number of small holes for drainage (water permeation) on the bottom of the main body. This is a structure in which a large number of aggregates and a flooring material bonded to each other with an adhesive or the like so as to create a desired gap between the aggregates are buried inside the flooring material receiver.

The drainage ditch cover of the present invention has sufficient strength by using a main body with a structure similar to that of a conventional cover, and also has a floor material receptacle formed integrally with the main body and a floor material buried inside it. As a result, even more strength is obtained, and since the floor material is made of aggregate bonded with the desired voids, sufficient water permeability can be obtained through the voids and the small holes in the floor material receiving surface. Further, the lid surface is covered with a flooring material, and since the surface of this flooring material is a substantially smooth surface, it is possible to walk on it smoothly without any hindrance. Don't fall. Furthermore, since it is possible to block objects from falling into the drains and squares, it is possible to prevent the accumulation of garbage and the like in the drains and squares, making cleaning them easier.

Furthermore, the drain cover of the present invention has other modifications, such as:
It is conceivable that a main body with a structure similar to that of a conventional lid and a floor material receptacle are formed as separate structures and fixed together with fixing screws. A floor material receiver with a large number of small holes for water permeation formed on the bottom of the floor material receiver is fixed together with fixing screws, and a large number of aggregates are bonded inside the floor material receiver with an adhesive or the like so that the desired voids are created. The flooring is bonded with

The drain cover of the present invention is substantially the same as the drain cover of the present invention in terms of strength, water permeability, walking on it, etc., and furthermore, the main body and floor material holder are separate. Since they can be manufactured easily, they can be manufactured easily, and they can be assembled simply by screwing, which reduces costs. Furthermore, since the main body may have the same or similar structure as the conventional lid, the conventional lid can be used as is, and the structure is such that it is possible to improve an already installed one.

〔Example〕

Next, an example of the drain cover of the present invention will be shown.

Figures 1 and 2 are diagrams showing the first embodiment of the present invention in a state where no flooring material is embedded. Figure 1 is a partially cutaway plan view, and Figure 2 is a cross-sectional view. It is a diagram. In the figure, reference numeral 1 indicates a structure in which a large number of bearing bars 2 and a cross bar 3 extending perpendicularly thereto are combined in a lid main body at regular intervals. Reference numeral 5 denotes a floor material receptacle integrally formed on the surface of the lid main body 1, which includes a bottom plate 6 having a large number of small holes 7 for water permeation, and a low (narrow) side plate 8 formed around the bottom plate 6. It is shaped like a shallow dish.

In the structure as described above, a composite material made of aggregate such as spherical or other shaped gravel and adhesive is poured into the inside of the floor material receiver 5, and the aggregate is bonded so that voids are created, so that the surface is relatively smooth. Form a flat flooring.

If the lid of this example is used for a drain,
The lid body has the same strength as conventional lids, and the floor material holder and floor material further increase the strength. It is used as a cover for drains such as drains, etc., and will not be damaged even if a car rides on it. On the other hand, since the surface of the lid is almost smooth due to the floor material, it is not only easy to walk on it, but also prevents shoes and other items from getting caught or falling into the groove. In addition, the floor material is water permeable due to the presence of voids, and since a large number of small holes 7 are provided in the bottom 6 of the floor material receiver 5, the water permeability can be maintained sufficiently.

FIG. 3 is a sectional view of the second embodiment. In this embodiment, the lid main body 1 and the floor material receiver 5 are formed separately and are connected by fixing screws.

In FIG. 3, screws 10 such as bolts are fixed in advance to the floor material receiver 5 by welding or other joining means. This floor material receiver 5 and the lid body 1 are combined into a board 1
2 and a nut 11. This is followed by a floor material receiver 5 as in the first embodiment.
This is a type of building with flooring material added to it.

In this embodiment, since the lid body 1 and the floor material receiver 5 are constructed separately, each part is lightweight and the parts can be easily transported.

Furthermore, since the structure of the lid main body 1 is similar to a conventional drain cover, the conventional lid can be used as is.

The size and number of small holes 7 formed in the bottom plate 6 of the floor material receiver 5 in both of the above embodiments can be determined as appropriate by considering the size of the aggregate and the balance between water permeability and the strength of the lid. desirable. Furthermore, in the second embodiment, it is also possible to fix the fixing screws using small holes provided in the floor material holder instead of joining them to the floor material holder in advance. In this way, it is also possible to transport the parts separately and assemble them on site.

[Effects of the invention] The drainage ditch cover of the present invention combines a lid body made of bar kneaded into a lattice shape, etc., and a flooring material receptacle with permeable holes, and a water-permeable flooring material is embedded in the flooring material receptacle. Since it is made of a metal material, it maintains the same water permeability as conventional products and has even greater strength, and has many other benefits such as being able to walk freely on the lid and preventing falling objects from entering the groove. It has the following.
