Description

Case of sidewalk block with water permeability}

The present invention relates to a permeable sidewalk block case, and more specifically, to a permeable sidewalk block case that can be assembled in various sizes and can smoothly drain rainwater to the ground surface during rainy weather.

In general, multiple sidewalk blocks of the same shape are installed in succession on the sidewalks of roads where people frequently pass, or on the road surfaces in large squares and parks, to allow pedestrians to pass comfortably, and to protect against snow and rainwater. This prevents road surface loss and provides a comfortable walking environment.

Most of these sidewalk blocks are made of concrete structures with a certain thickness and size and are assembled and constructed in a continuous form on the road surface where leveling work has been completed.

After construction is completed, gaps will appear between the sidewalk blocks. During rainy weather, only a very small amount of rainwater will seep into the underlying ground soil through the gaps in the blocks, and most of the rainwater will not be inundated but will instead pass over the surface of the sidewalk blocks. Therefore, it flows down and is drained through sewer pipes.

In this way, the rainwater that accumulates on the upper part of the sidewalk block hardly permeates to the ground surface, so the interior of the ground surface where the sidewalk block is constructed not only changes into an environment that inhibits the growth of microorganisms, but also reduces the drainage capacity of sewer pipes in areas with weak drainage facilities. There was a problem with the load.

Republic of Korea Patent Publication No. 10-2012-0047886 discloses a sidewalk block case with bottom projections.

The sidewalk block case has vertical grooves formed on the sides to encourage rainwater to move to the ground surface along the vertical grooves during rainy weather, but the size of the vertical grooves is very small and there is a problem in that they are easily filled with soil or sand. In addition, when rainwater flows into the vertical grooves, there is a problem that it is difficult for the rainwater to flow in because the space of the vertical grooves is filled with air.

In addition, since many sidewalk block cases are constructed with a large number of sidewalk block cases placed on the ground, there is a problem in that the bonding force between sidewalk block cases is weak and it takes a long time to align them in a straight line.

Hereinafter, a permeable sidewalk block case according to a preferred embodiment of the present invention will be described in detail.

The permeable sidewalk block case of the present invention has a modular structure so that a plurality of sidewalk blocks can be accommodated. These sidewalk block cases are constructed so that two or more can be assembled by connecting them in all directions. Therefore, the sidewalk block case of the present invention can be prepared in an appropriate number and assembled into various sizes.

Referring to Figures 1 to 7, the permeable board block case of the present invention includes a main body 10 provided with a plurality of receiving spaces 11 and 12 in which the sidewalk block 5 is accommodated, and receiving spaces 11, 12), the drainage 20 is formed between the side walls of the adjacent receiving spaces 11 and 12, and in rainy weather, rainwater flows in between the side walls of the sidewalk block 5 and the receiving spaces 11 and 12, forming a drainage channel ( The upper part of the drainage channel 20 connects the guide grooves 15 formed vertically on the inside of the side walls of the receiving spaces 11 and 12 so that the flow can flow into the 20) and the upper ends of the side walls of the receiving spaces 11 and 12. It is provided with a connecting rib 30 formed to cover.

The main body 10 is provided with a plurality of accommodation spaces 11 and 12 in which the sidewalk blocks 5 are accommodated.

In the illustrated example, five receiving spaces 11 and 12 are formed in the main body 10. A sidewalk block (5) is inserted and coupled to each receiving space (11, 12). The sidewalk block 5 is made of concrete. The shape of the receiving spaces 11 and 12 may also change depending on the shape of the sidewalk block 5. In the illustrated example, the accommodation spaces 11 and 12 are formed in a square shape to accommodate the rectangular parallelepiped-shaped sidewalk block 5.

The receiving spaces 11 and 12 can be divided into two types. One type of receiving space, that is, the first receiving space 11, forms a space in which sidewalk blocks of a certain size are accommodated in their intact form. And another type of accommodation space, that is, the second accommodation space 12, forms a space where split sidewalk blocks are accommodated. Accordingly, the second receiving space 12 is formed smaller than the first receiving space 11. In the illustrated example, the second receiving space 12 is formed to be 1/2 the size of the first receiving space 11 to accommodate a half sidewalk block split in half.

In the illustrated example, three first receiving spaces 11 are formed and two second receiving spaces 12 are formed. Two first receiving space parts 11 are formed side by side in the front row, and one is formed in the back row. The first receiving space 11 formed in the back row is arranged to be staggered with the two receiving space parts 11 formed in the front row.

And the second receiving space 12 is disposed on each side of the first receiving space 11 formed in the back row.

The first receiving space 11 consists of a floor and side walls formed at a certain height on the front, rear, left and right sides of the floor. And the second receiving space 12 is formed by cutting the first receiving space 11 in half. Accordingly, the bottom, front side wall, and rear side wall of the second receiving space 12 are half the size of the bottom, front side wall, and rear side wall of the first receiving space 11.

This is a space in which one complete sidewalk block can be accommodated by combining the second receiving space portion 12 of one sidewalk block case with the second receiving space portion of the adjacent sidewalk block case when assembling multiple sidewalk block cases. It is to form.

The bottom of the receiving space (11, 12) serves to support the lower part of the sidewalk block (5). The bottom of the receiving space portions 11 and 12 is formed with a number of penetrating portions to improve breathability and drainage.

A plurality of downward protruding protrusions 14 are formed on the bottom surfaces of the receiving spaces 11 and 12. These protrusions 14 separate the main body 10 from the ground surface to increase breathability and drainage. In addition, when constructing a sidewalk block case after laying sand or crushed stone on the ground surface, the lower part of the protrusion 14 becomes embedded in the sand or crushed stone, thereby increasing the bearing capacity of the main body 10.

The side walls of adjacent receiving spaces 11 and 12 are spaced apart from each other. Therefore, an empty space is formed between the side walls, and this empty space is the drainage channel 20. Accordingly, the drainage channel 20 is formed between the side walls of adjacent receiving spaces among the receiving spaces 11 and 12.

The upper part of the drainage channel 20 is blocked by the connecting rib 30. This connecting rib 30 is formed to cover the upper part of the drainage channel 20 by connecting the upper ends of the side walls of the receiving spaces 11 and 12.

Meanwhile, the connecting rib 30 is not formed on the upper part of the side wall of the first receiving space 11. This is to ensure that the connecting rib 30 formed on one sidewalk block case can be coupled to an adjacent sidewalk block case when assembling a plurality of sidewalk block cases.

In case of rain, a guide groove (15) is formed on the inside of the side wall of the receiving space (11, 12) so that rainwater flows in between the sidewalk block (95) and the side wall of the receiving space (11, 12) and flows into the drainage channel (20). .

In the illustrated example, one or two guide grooves 15 are formed on the side wall. The guide groove 15 is formed to be long in the vertical direction. The lower part of the guide groove 15 is connected to the drainage channel 20.

A plurality of exhaust holes 35 are formed in the connecting rib 30 so that the air in the drain 20 can be discharged to the outside of the main body 10 when rainwater flows into the drain 20 through the guide groove 15. do. The exhaust holes 35 are formed on the connecting ribs 30 at regular intervals.

The main body 10 is provided with an assembly bracket 50 and an insert portion 55 to ensure strong coupling when assembling multiple sidewalk block cases.

The assembly bracket 50 is formed on one side of the main body 10. In the illustrated example, the assembly bracket 50 is formed to protrude from the outside of the side wall of a portion of the first receiving space 11 where the connecting rib 30 is not formed. Inside the assembly bracket 20, an insertion hole 51 is formed to be long in the vertical direction. And, fitting slots 53 are formed on the upper part of the assembly bracket 50 in an upward and downward direction.

The insert portion 55 is formed on the other side of the main body 10 and is provided in a position symmetrical to the assembly bracket 50. The insert portion 55 includes a protruding lip 56 formed vertically long to fit into the fitting slot 53, and a wedge portion 57 formed on the protruding lip 56 and inserted into the insertion hole 51.

By using the above-described assembly bracket 50 and insert portion 55, when assembling multiple sidewalk block cases, assembly is very simple and bonding force can be increased.

Meanwhile, the sidewalk block case of the present invention can be manufactured by injection molding with synthetic resin. In this case, it is desirable for the sidewalk block case to contain luminous material so that it can emit light at night.

A phosphorescent material is a material that absorbs and accumulates light energy from sunlight or an electrical light source and then emits the accumulated light at night or when the light is blocked. In the present invention, the afterglow luminance of the phosphorescent material is used to make the sidewalk block case emit light.

Phosphorescent materials can repeat the absorption-accumulation-emission process semi-permanently. Commercially available granular or powdery products can be used as photoluminescent materials. For example, strontium aluminate-based materials or zinc sulfide-based materials that are chemically and optically excellent can be used as phosphorescent materials. The stronger the phosphorescent material absorbs light energy and the greater the amount of phosphorescent material, the stronger the luminance.

During injection molding, if a certain amount of photoluminescent material is mixed with a synthetic resin material and melted to form a sidewalk block case, the molded sidewalk block case can emit luminous light. Accordingly, it is possible to create a beautiful scenery while giving the sidewalk visibility at night.

Above, the present invention has been described with reference to one embodiment, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom. Therefore, the true scope of protection of the present invention should be determined only by the appended claims.
