Floor block structure with excellent water permeability {FLOOR BLOCK STRUCTURE HAVING ENHANCED WATER PERMEABILITY}

The present invention relates to a floor block structure having excellent water permeability. In more detail, the present invention relates to a floor block structure having excellent water permeability by forming a space that can be filled with foreign substances such as sand on the side and the bottom of the sidewalk block.

In recent years, in road development and various landscaping works related thereto, various road pavement materials having permeable properties have appeared as one method for preserving an eco-friendly ecosystem by reducing rainwater to nature.

Among them, the need for a floor block structure capable of beautifully creating the surrounding vegetation environment is emerging for the purpose of placing importance on the natural landscape.

Conventional floor structures used for pavements such as sidewalks, bicycle paths, and park trails do not sufficiently penetrate rainwater, and thus it is difficult to sufficiently utilize water resources such as rainwater.

As a prior art for solving this problem, the Korean Utility Model Registration No. 20-0245754 [Document 1] discloses a technical configuration for forming a groove 2 on the side of the block 1 for the sidewalk.

The block 1 for pedestrian roads according to the document 1 has a problem in that the groove 2 is blocked by foreign substances such as sand, and there is a high possibility that rainwater or the like cannot sufficiently penetrate.

As another prior art, Korean Utility Model Registration No. 20-0381399 [Document 2] discloses a technical configuration of forming a protruding surface 120 and a spacing support 130 on the side of the permeable sidewalk block 100. .

In this document 2, rainwater may flow into the space provided between the permeable sidewalk blocks 100.

However, in Document 2, there is a problem that the spacing between the water permeable sidewalk blocks 100 may be excessively large for sufficient penetration of rainwater, which may be disadvantageous in terms of design, and may also be disadvantageous in terms of stability.

For example, as shown in FIG. 7, the width d3a of the third lower groove portion 200b corresponding to the third side surface SP3 of the main body 10 in the first direction DR1 is the second direction DR2 It may be larger than the width of the furnace (d3b).

Here, the width d3a of the third lower groove portion 200b in the first direction DR1 may be referred to as the width d3a of the third lower groove portion 200b in a direction parallel to the third side surface SP3, The width d3b of the third lower groove 200b in the second direction DR2 may be referred to as the width d3b of the third lower groove 200b in the direction intersecting (vertical) with the third side SP3. have.

In this case, the size of the portion located at the central portion of the lower surface BS of the lower protrusion 500 can be increased, and thus the structural stability of the floor block structure 1A according to the present invention can be improved.

A view of the floor block structure 1A viewed from the side of the first side SP1 is shown in FIG. 8. In FIG. 8, the identification symbol h4 may mean the height h4 of the lower protrusion 500.

Referring to FIG. 8, the distance d10 between the first side groove 100a and the first side protrusion 300a may be different from the distance d11 between the first side groove 100a and the second side protrusion 300b. have.

These contents may be applied equally to the second side (SP2), the third side (SP3) and the fourth side (SP4) of the main body 10.

Meanwhile, the depth of the side groove portion 100 may be increased from the upper surface US to the lower surface BS of the main body 10.

For example, as in the case of FIG. 9, the depth h1b of the side grooves 100, 100a, 100b, 100c, 100d on the lower surface BS side of the main body 10 is the upper surface US of the main body 10 It may be greater than the depth h1a of the side grooves 100, 100a, 100b, 100c, and 100d from the side.

In this case, it is possible to suppress a decrease in drainage capacity due to clogging of the drainage passage by foreign substances such as sand.

In addition, it is possible to prevent an excessive increase in the distance between the floor block structure 1A and the adjacent floor block structure 1A from the top of the floor block structure 1A. Accordingly, it can be maintained in terms of design, and it can be advantageous in terms of stability, such as preventing the high heels from falling out.

In order to improve the storage capacity of foreign substances such as sand, the depth h3 of the lower groove portions 200, 200a, 200b, 200c, 200d is the maximum depth h1, It may be larger than h1a, h2b).

10 to 13 are views for explaining a lower groove portion and a central groove portion. Hereinafter, descriptions of the parts described above may be omitted.

Referring to FIG. 10, at least one central hollow part 600 that is depressed in a vertical direction (the third direction DR3) may be formed in the lower protrusion 500.

The depression direction of the lower groove portions 200, 200a, 200b, 200c, and 200d and the depression direction of the central groove portion 600 may be the same.

In the process of installing the floor block structure 1A, foreign substances such as sand may flow into the central groove part 600. Accordingly, it is possible to easily align the floor block structures 1A to maintain the horizontal.

In addition, the central groove portion 600 may be stored by introducing foreign substances such as sand partially introduced from the lower groove portions 200, 200a, 200b, 200c, and 200d.

Looking at the cross section cut along the A1-A2 line of the sea block structure 1A, as shown in FIG. It may be less than the maximum depth h3.

In addition, the maximum width W1 of the lower groove portions 200, 200a, 200b, 200c, 200d in the horizontal direction (the first direction DR1 or the second direction DR2) is the maximum width W2 of the central groove portion 600 Can be larger than ).

Here, the maximum width W1 of the lower groove portions 200, 200a, 200b, 200c, 200d in the horizontal direction (first direction DR1 or second direction DR2) is the side groove portions 100, 100a, 100b, 100c , 100d) may mean the width of the lower groove portions 200, 200a, 200b, 200c, 200d.

For example, the maximum width W1 of the first lower groove portion 200a is the first lower groove portion in the first direction DR1 in a region overlapping with the first side groove portion 100a formed on the first side surface SP1 It may mean the width of (200a). These contents may be equally applied to the second lower groove portion 200b, the third lower groove portion 200c, and the fourth lower groove portion 200d.

Meanwhile, in the horizontal direction (the first direction DR1 or the second direction DR2), the widths of the lower groove portion 200 and/or the central groove portion 600 may be different from each other in the inlet portion and the bottom portion.

For example, as shown in FIG. 12A, the width W1a at the entrance portion of the lower groove portion 200 in the horizontal direction (the first direction DR1 or the second direction DR2) is It may be larger than the width W1b.

Here, both side surfaces SL1 of the cross section of the lower groove part 200 in the horizontal direction (first direction DR1 or second direction DR2) may have a predetermined inclination. Here, both side surfaces SL1 of the lower groove part 200 may be referred to as a first inclined surface SL1.

In other words, the lower groove portion 200 may include a portion in which the cross-sectional widths W1a and W1b gradually decrease.

In addition, as shown in FIG. 12B, the width W2a at the entrance portion of the central groove 600 in the horizontal direction (the first direction DR1 or the second direction DR2) is the width at the bottom portion ( W2b) can be larger.

Here, both side surfaces SL2 of the cross-section in the horizontal direction (first direction DR1 or second direction DR2) of the central groove part 600 may have a predetermined inclination. Here, both side surfaces SL2 of the central groove part 600 may be referred to as a second inclined surface SL2.

In other words, the central groove part 600 may include a portion in which the cross-sectional widths W2a and W2b gradually decrease.

When comparing (A) and (B) of FIG. 12, it can be seen that the slope of the first inclined surface SL1 of the lower groove part 200 is greater than that of the second inclined surface SL2 of the central groove part 600. .

In this case, the storage capacity of the lower groove portion 200 may be further increased.

15 is a view of a first floor block structure 1Aa, a second floor block structure 1Ab, a third floor block structure 1Ac, and a fourth floor block structure 1Ad viewed from above.

FIG. 15 shows a view of the first floor block structure 1Aa, the second floor block structure 1Ab, the third floor block structure 1Ac, and the fourth floor block structure 1Ad viewed from the bottom.

Referring to FIG. 15, not only the side grooves 100 but also the lower grooves 200 may be positioned adjacent to each other. For example, the first lower groove portion 200a of the first floor block structure 1Aa and the third lower groove portion 200c of the fourth floor block structure 1Ad are formed by the first floor block structure 1Aa and the second floor. They may be located adjacent to each other at the boundary of the block structure 1Ab. In this case, the storage capacity of the lower groove part 200 may be further improved.

When looking at a cross section of the first floor block structure 1Aa and the second floor block structure 1Ab along the line A3-A4, as shown in FIG. 16, it can be seen that the side grooves 100 are located adjacent to each other. In this case, two adjacent side grooves 100 commonly form a passage through which foreign substances such as sand can enter, thereby improving the ability to transmit moisture such as rainwater.

In addition, referring to FIG. 16, the maximum depth h3 of the lower groove portion 200 may be greater than the maximum depth h1b of the side groove portion 100. In this case, the storage capacity of the lower groove portion 200 may be further improved, and the water permeability of the floor block structure 1A may be further improved.
