Description

[Technical field]

[0001] The present invention relates to blocks that are arranged side by side on a surface to protect the surface of a structure such as a slope. [Background technology]

[0002] Conventionally, various construction methods have been used to protect the surface of structures such as slopes. For example, block-laying work is a method used on gentle slopes of about 20 to 30 degrees to prevent erosion caused by weathering of the soil of the slope and rainwater. This block-laying work is also generally implemented as a revetment work on river slopes and reservoir slopes to prevent erosion caused by river flow and water level fluctuations. In addition to block-laying work, concrete-laying and sheet-laying are also used as such slope protection works. On the other hand, conventional slope protection works (block-laying work using concrete blocks, concrete-laying, sheet-laying) implemented to protect river banks and reservoir slopes have caused many accidents due to people, especially children, entering rivers and reservoirs by mistake, and most of these accidents are caused by people slipping down and not being able to climb the slope and drowning. For this reason, the surfaces of the blocks used in these construction methods are designed to have a depression in the center, so that people can put their feet in the depression or the protrusions around the depression to climb up slopes, etc. However, blocks with a depression in the center have the problem that water tends to accumulate in the depression, which not only ruins the aesthetic look with dirt and moss growing on them, but also makes the blocks slippery. In addition, depending on the material of the blocks, the surface can be slippery. Summary of the Invention [Problem to be solved by the invention]

[0003] In view of the above problems, the present invention provides a block on which people can place their feet, which is less likely to collect water on its surface, and which is less likely to be slippery. [Means for solving the problem]

[0004] In order to solve the above problems, the block according to claim 1 of the present invention is a block to be laid out without gaps on an installation surface, and comprises a main body having a front and a back surface, the front surface of the main body being a flat surface extending to at least one side of the main body, the back surface of the main body being a mounting surface to be placed on the installation surface, the surface of the main body being provided with a plurality of grooves and a footrest protrusion, and the main body being provided with a drainage portion for drainage adjacent to the footrest protrusion.

[0005] According to the above features, the footrest protrusions can be used to place feet, making it easier for people to climb up slopes. The grooves on the surface prevent feet from slipping, making it even easier for people to climb up slopes. In addition, the surface of the main body is a flat surface that extends to at least one side of the main body, preventing rainwater from remaining on the blocks for long periods of time and preventing the growth of moss, algae, etc. on the blocks, thereby preventing them from becoming slippery. Furthermore, a drainage section is provided adjacent to the footrest protrusions, allowing rainwater to be efficiently drained without accumulating around the footrest protrusions.

[0006] In order to solve the above problem, the block according to claim 2 of the present invention is characterized in that the plurality of groove portions are a plurality of lateral grooves provided on the surface of the main body portion.

[0007] According to the above-mentioned features, the grooves are lateral grooves, which is particularly effective in preventing foot slippage.

[0008] In order to solve the above problems, the block according to claim 3 of the present invention is characterized in that the drainage portion is a drainage groove provided on a side surface of the main body portion.

[0009] According to the above feature, rainwater, etc. on the surface of the block can be efficiently drained through the drainage grooves on the side, which has the effect of preventing the growth of moss, algae, etc., which makes the surface slippery.

[0010] In order to solve the above problem, the block according to claim 4 of the present invention is characterized in that the drainage portion is an opening that leads from the front surface of the main body portion to the back surface of the main body portion.

[0011] According to the above feature, the openings allow rainwater, etc. on the front surface of the block to be efficiently drained to the back surface, which has the effect of preventing the growth of moss, algae, etc., which would otherwise make the block slippery.

[0012] In order to solve the above problems, the block according to claim 5 of the present invention is characterized in that it has flat surfaces extending to both side surfaces of the main body.

[0013] According to the above feature, rainwater and the like does not accumulate on the surface, but is effectively drained from both side surfaces. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The block (100) according to the present invention will be described below. Fig. 1 is a perspective view of the block (100). Fig. 2(a) is a plan view of the block (100), and Fig. 2(b) is a bottom view of the block (100). Fig. 3(a) is a right side view of the block (100), and Fig. 3(b) is a left side view of the block (100). Fig. 4(a) is a front view of the block (100), and Fig. 4(b) is a rear view of the block (100).

[0016] The block (100) is made of concrete and has a main body (200), which has a front surface (210) and a back surface (220). The main body (200) further has a right side surface (230) and a left side surface (240). The main body (200) further has a front surface (250) and a back surface (260). The main body (200) further has a drainage section (270) for drainage. The back surface (220) serves as a mounting surface to be placed on an installation surface such as a slope, which will be described later.

[0017] The surface (210) is a flat surface extending to at least one side surface. In FIG. 1, an example in which the surface (210) extends to both the right side surface (230) and the left side surface (240) is shown, but the present invention is not limited to this, and the surface (210) may extend to one side of the right side surface (230) or the left side surface (240). In this case, the other side that is not flat may have a convex portion. The surface (210) has a plurality of grooves (211). Furthermore, the surface (210) has a lower footrest convex portion (212). Furthermore, the surface (210) may have an upper footrest convex portion (213). The lower footrest convex portion (212) protrudes from the surface (210) and is a convex portion provided on the front side of the surface (210). The upper foothold protrusion (213) also protrudes from the front surface (210) and is a protrusion provided on the back surface (260) of the front surface (210). In Fig. 1, the lower foothold protrusion (212) is shown as an example of a protrusion extending from the right side surface (230) to the left side surface (240), but is not limited to this, and the lower foothold protrusion (212) may extend to either the right side surface (230) or the left side surface (240). In addition, the lower foothold protrusion (212) may not extend to either the right side surface (230) or the left side surface (240). Similarly, the upper foothold protrusion (213) is shown in Fig. 1 as an example extending from the right side surface (230) to the left side surface (240), but is not limited thereto and the upper foothold protrusion (213) may extend to either the right side surface (230) or the left side surface (240). Also, the upper foothold protrusion (213) may not extend to either the right side surface (230) or the left side surface (240).

[0018] In FIG. 1, the grooves (211) are shown as parallel straight grooves (211) that are equally spaced from one another, but the present invention is not limited thereto, and the grooves (211) may not be equally spaced from one another or straight. If the grooves (211) are straight, they may be lateral grooves as shown in FIG. 1, vertical grooves, diagonal grooves, etc. Note that the lateral grooves are grooves that extend toward the right side surface (230) and the left side surface (240) on both sides. Note that the vertical grooves are grooves that extend toward the front surface (250) and the back surface (260) on the front and rear sides. Note that the interval between adjacent grooves (211) may be narrow or wide relative to the opening width of the grooves (211). For example, the grooves (211) may be straight lines, wavy lines, or patterns, as long as they can provide a slip prevention effect as described below. Furthermore, the grooves (211) do not have to extend to one side, and may be provided only in a part of the surface (210) (for example, an arbitrary part such as the center of the surface (210)). The cross-sectional shape of the grooves (211) may be rectangular, V-shaped, U-shaped, etc. The depth of the grooves (211) can be freely selected within a range that does not affect the strength of the main body part (200). The depths of the multiple grooves (211) may be the same or different from each other. The surface (210) on which the grooves (211) are provided is flat and is lower than the upper surfaces of the lower footrest protrusions (212) and upper footrest protrusions (213). The distance between adjacent grooves (211) is narrower than the width of the upper surface of the lower footrest protrusions (212) or upper footrest protrusions (213).

[0019] The lower footrest protrusion (212) protrudes upward from the surface (210). An inner connecting surface (214) connecting the surface (210) and the upper end surface of the lower footrest protrusion (212) may be vertical or inclined obliquely upward. Since the inner connecting surface (214) is a place that can be used optionally when placing a foot, the inner connecting surface (214) does not necessarily have to be configured so that a foot can be placed thereon, and may be configured in any manner. An outer connecting surface (215) connecting the upper end surface of the lower footrest protrusion (212) and the front surface (250) may be vertical or inclined obliquely downward.

[0020] The upper leg projection (213) protrudes upward from the surface (210). An inner connecting surface (216) connecting the surface (210) and the upper end surface of the upper leg projection (213) may be vertical or inclined obliquely upward. An outer connecting surface (217) connecting the upper end surface of the upper leg projection (213) and the back surface (260) may be vertical or inclined obliquely downward.

[0021] Here, the surface areas of the flat surfaces of the upper parts of the lower foot-hold protrusion (212) and the upper foot-hold protrusion (213) are respectively S2 and S3. The area of ​​the surface (210) excluding the lower foot-hold protrusion (212) and the upper foot-hold protrusion (213) is S1. The area S2 or S3 may be the same as the area S1, or may be larger or smaller than the area S1. In either case, the lower foot-hold protrusion (212) is designed to function as a foot-hold protrusion so that a space is provided between the protrusions to allow the toes to be placed. It is desirable that the distance between the protrusions is sufficiently larger than the thickness of a typical shoe toe. The distance between the protrusions means the distance between the inner connecting surface (214) and the inner connecting surface (216) when the upper foot-hold protrusion (213) is provided, and the distance between the inner connecting surface (214) and the back surface (260) when the upper foot-hold protrusion (213) is not provided.

[0022] The drainage section (270) is a drainage groove provided on at least one of the right side surface (230) and the left side surface (240). The drainage section (270) is not limited to the form of a drainage groove, and may be, for example, an opening in the form of a through hole provided on the front surface (210) leading to the back surface (220). The main body section (200) may have a drainage groove and an opening at the same time, or may have a plurality of each. When the drainage section (270) is provided adjacent to the lower footrest protrusion (212) (specifically, when the drainage section (270) is disposed below the center of the block (100) placed at an angle), the drainage section (270) can drain water more efficiently. Furthermore, the drainage section (270) may be provided on the inner connecting surface (214) in addition to the flat surface of the front surface (210). When the drainage portion 270 is a groove, the cross-sectional shape of the drainage portion 270 may be rectangular, V-shaped, U-shaped, etc. When the drainage portion 270 is an opening in the form of a through hole, the shape of the opening may be polygonal, round, etc. When the drainage portion (270) is a drainage groove, the groove extends from the front surface (210) to the back surface (220). The groove may extend from the front surface (210) perpendicularly to the back surface (220), or may extend obliquely toward the back surface (220) while being slightly inclined toward the front or back surface (260). The drainage portion (270) may extend from the flat surface of the front surface (210) or from the inner connecting surface (214) toward the back surface (220). The drainage portion (270) is preferably disposed adjacent to the back surface (220) or in the periphery thereof. The drainage portion (270) may be disposed so as to be in contact with the groove (211) extending to the side surface.

[0023] When the drainage portion (270) is a drainage groove provided on one side of the main body portion (200) and the surface (210) is a flat surface extending to one side surface, the drainage portion (270) is positioned on the side surface of the one side to which the flat surface extends.

[0024] When the blocks (100) are laid out, the front surface (250) of one adjacent block (100) and the back surface (260) of the other adjacent block (100) are placed so that they abut against each other. The front surface (250) and the back surface (260) may be provided with uneven parts for fitting. When the uneven parts are provided, the concave part recessed from the lower foothold protrusion (212) of the front surface (250) includes a front upper part (251) on the front side of the lower foothold protrusion (212) of the front surface (250), a front lower surface (253) recessed inward from the front upper part (251), and a front connecting surface (252) connecting the front upper part (251) and the front lower surface (253) in a stepped manner. The convex portion protruding from the upper leg rest convex portion (213) of the back surface (260) includes a back surface lower surface (263) protruding furthest toward the back surface (260), a back surface upper surface (261) recessed inward from the back surface lower surface (263), and a back surface connecting surface (262) connecting the back surface lower surface (263) and the back surface upper surface (261) in a stepped manner. When the blocks (100) are laid out, the blocks are fitted together so that the front upper portion (251) of one adjacent block (100) abuts against the back surface upper surface (261) of the other adjacent block (100), the front lower surface (253) of one block (100) abuts against the back surface lower surface (263) of the other block (100), and further the front connecting surface (252) of one block (100) abuts against the back connecting surface (262) of the other block (100). The height of the front lower surface (253), i.e., the distance from the back surface (220) to the front connecting surface (252), is H1. The height of the rear lower surface (263), i.e., the height from the back surface (220) to the rear connecting surface (262) is H2. The height H1 is greater than the height H2. The rear connecting surface (262) may be inclined obliquely downward toward the outside of the main body (200). By inclining the rear connecting surface (262) obliquely downward, it may be possible to adjust the angle between the laid-out blocks (100) in accordance with the angle of the installation surface.

[0025] The left side surface (240) has a left side edge portion (241), a left side edge portion (242), and a left side edge portion (243), which are outer edges that contact the lower back surface (263), the rear connecting surface (262), and the upper back surface (261), respectively, and further has a left side edge portion (244), a left side edge portion (245), and a left side edge portion (246), which are outer edges that contact the lower foothold protrusion (212), the flat surface of the front surface (210), and the upper foothold protrusion (213), and further has a left side edge portion (247), a left side edge portion (248), and a left side edge portion (249), which are outer edges that contact the upper front surface (251), the front connecting surface (252), and the lower front surface (253), respectively, and further has a left side edge portion (221), which is an outer edge that contacts the back surface (220). The outer edges of the left side surface (240), i.e., left side edge (241), left side edge (242), left side edge (243), left side edge (244), left side edge (245), left side edge (246), left side edge (247), left side edge (248), and left side edge (249), may be chamfered to remove the corners. The corresponding outer edges of the right side surface (230) may be similarly chamfered to remove the corners.

[0026] Fig. 5 is a perspective view of the blocks (100) when multiple blocks (100) are arranged and installed on an arbitrary inclined surface (installation surface) such as a slope, with the block (100A) arranged and installed in the top row. Fig. 6 is a left side view of the blocks (100) arranged and installed. The surface formed by the continuous surfaces (210) when the blocks (100) are arranged and installed is called the continuous surface (310).

[0027] Note that the block (100) may be installed after a wicking prevention agent is laid on the installation surface (400). As shown in Figures 5 and 6, the block (100A) has an upper footrest protrusion (213A) corresponding to the upper footrest protrusion (213) of the block (100) shown in Figure 1 designed to be higher than the upper footrest protrusion (213). The components of the block (100A) other than the upper footrest protrusion (213A) are the same as those of the block (100).

[0028] The blocks (100) adjacent to each other vertically may be arranged so that their right side surfaces (230) or left side surfaces (240) are aligned vertically in a straight line, that is, aligned vertically in a straight line, or may be arranged offset horizontally. When the blocks (100) are arranged so that their right side surfaces (230) or left side surfaces (240) are aligned in a straight line, the surface formed by each successive right side surface (230) is the right side surface (330), and the surface formed by each successive left side surface (240) is the left side surface (340).

[0029] As shown in FIG. 6, the continuous surface (310) is formed with regularly-spaced continuous lower foothold protrusions (212) and upper foothold protrusions (213).

[0030] When the blocks (100) are installed in a line outdoors, rainwater that falls on the continuous surface (310) flows through the drainage parts (270) onto the installation surface (400). Because the drainage parts (270) are regularly arranged on the continuous surface (310), rainwater is drained without concentrating in one place, so there is no need to worry about erosion of the installation surface (400) by rainwater.

[0031] When the blocks (100) are installed outdoors, rainwater that falls on the continuous surface (310) flows through the drainage section (270) to the installation surface (400). The rainwater is effectively drained regularly from the drainage section (270), preventing the rainwater from remaining on the blocks for a long period of time. This prevents moss, algae, and the like from growing on the blocks.

[0032] Since the drainage portion (270) is adjacent to the lower footrest protrusion (212), rainwater that accumulates between the surface (210) and the lower footrest protrusion (212) can be efficiently drained.

[0033] As shown in FIG. 5, the surface (210) of the block (100) is a flat surface extending to at least one side surface, so that rainwater, etc. does not accumulate on the surface (210) but is drained to the side surface. In particular, when the surface (210) of the block (100) is a flat surface extending to both side surfaces, rainwater, etc. does not accumulate on the surface (210) but is effectively drained from both side surfaces. Also, as shown in FIG. 5, the surfaces (210) of the blocks (100) that are laid out without gaps and adjacent to each other on the left and right form a flat continuous surface (310) that is continuous with each other. Therefore, rainwater, etc. does not accumulate on the continuous surface (310) but is drained continuously to the left and right.

[0034] As shown in Fig. 5, when blocks (100) having surfaces (210) with flat surfaces extending on both sides are installed side by side, rainwater falling on the surfaces is drained from the drainage sections (270) on the continuous surface (310). Even if the drainage capacity of some of the drainage sections (270) on the continuous surface (310) is reduced due to clogging or the like, the rainwater can be efficiently drained from another drainage section (270) on the continuous surface (310).

[0035] In the case where the drainage portion (270) is a groove installed on the right side (230) or the left side (240), the drainage efficiency of rainwater can be further improved by chamfering the outer edge of the same side as the drainage portion (270).

[0036] As shown in Fig. 5, when blocks (100) each having a flat surface extending to both sides of the surface (210) are arranged side by side with no gaps, rainwater falling on the surface is drained from the drainage section (270) on the continuous surface (310). When the drainage section (270) is a groove provided on the right side surface (230) or the left side surface (240), rainwater is efficiently drained not only from the drainage section (270) provided on each block (100) but also from the drainage section (270) of another block (100). For example, even if the drainage capacity of some of the drainage sections (270) provided on the side surface of the block (100) (the drainage section (270) of the right block (100) in Fig. 5) is reduced due to clogging or the like, rainwater is efficiently drained from the drainage section (270) of another block (100) (the drainage section (270) of the adjacent left block (100) in Fig. 5).

[0037] Rainwater is also efficiently drained when the drainage section (270) is a groove provided on the right side surface (230) or the left side surface (240). Furthermore, when the side surface on which the drainage groove is provided as the drainage section (270) and the edge of the same side surface are chamfered, rainwater on the surface of the block is even more efficiently drained. For example, when a drainage groove is provided as the drainage section (270) on the left side surface (240) of the block (100), rainwater on the surface of the block flows along the left side surface edge (244), the left side surface edge (245), or the left side surface edge (246) and is more efficiently guided to the drainage section (270). When the drainage section (270) is an opening leading to the back surface, rainwater on the surface is efficiently drained from the drainage section (270) provided in each block (100).

[0038] As shown in Fig. 5, when blocks (100) each having a flat surface extending on both sides of the surface (210) are installed side by side with no gaps, rainwater that accumulates between the outer connecting surface (215) and the outer connecting surface (217) of the vertically adjacent blocks (100) drains to the back surface through the space formed by the chamfered edges of the adjacent blocks (100). For example, when the edge of the left side surface (240) of the block (100) is chamfered, rainwater drains from the continuous surface (310) of the block to the back surface through the space formed by the left side edge (247) and the left side edge (243), the left side edge (248) and the left side edge (242), and the left side edge (249) and the left side edge (241).

[0039] When the blocks are placed side by side, the continuous surface (310) has regular grooves (211). When a person climbs a slope on which the blocks (100) are placed, the grooves (211) of the continuous surface (310) prevent the feet from slipping. In particular, since the grooves (211) are horizontal grooves, they are highly effective in preventing the feet from slipping.

[0040] When placed side by side, the grooves (211) in the continuous surface (310) reduce reflection of light on the continuous surface (310).

[0041] When a person climbs a slope on which the blocks (100) are installed, the person can place his / her feet on the continuous lower footrest protrusions (212) formed when the blocks are installed side by side, making it easier for the person to climb the slope.

[0042] When the blocks (100A) are installed in the top row as shown in FIG. 5, the height of the upper footrest protrusion (213A) is higher than that of the upper footrest protrusion (213), so that stones and other objects can be prevented from falling from the top of the slope.

[0043] If the front (250) and rear (260) are provided with projections and recesses for fitting, when the blocks (100) are placed side by side on a slope, the front connecting surface (252) presses the rear connecting surface (262) from above, as shown in Fig. 6. This structure allows the upper block to press the lower block toward the installation surface (400), preventing each installed block (100) from coming loose and falling.

[0044] In addition, the blocks of the present invention are not limited to the above examples, and various modifications and combinations are possible within the scope and embodiment described in the claims of the utility model registration, and these modifications and combinations are also included in the scope of the rights.
