Description

  The present invention relates to a laying block and a detachable tool used for the laying block.

  Conventionally, as an example of a concrete laying block, one having a hollow space for vegetation on a part of its surface (for example, a central portion) has been used. Such laying blocks can improve the greening rate by planting vegetation by rooting grass in the hollow space.

That is, for example, when laid in a parking lot, since the tire is placed on a concrete molding portion other than the hollow space, this concrete molding portion supports the wheel load of the vehicle, thereby ensuring the function of the laying block, while the lawn in the hollow space. Planting such as vegetation can realize greening on the surface of the laying block, thereby improving the landscape of the parking lot and further suppressing the occurrence of water pools by infiltration of rainwater into the hollow space (Patent Document 1).
JP 07-150505 A

  By the way, since the lawn and the like vegetated in the hollow space of the laying block described above is softer than the concrete molded part, for example, when the toes and heels step on the vegetated hollow space during walking, the toes and heels sink. Therefore, there is a problem that the walking ability becomes worse.

  Also, during this subduction, the soil under the lawn may become mud and adhere to the shoes.

  These problems are the same when passing by a stroller having a small wheel diameter or a wheelchair (the wheel diameter of the front wheel is small), and improvement in running performance is required.

  Note that this problem does not only occur in the parking lot where the above-described laying block is laid, but can be similarly caused when laid in a place where a person, a stroller, a wheelchair or the like passes.

  In order to solve such a problem, for a place where a person walks, etc., it is sufficient to lay a block in which a hollow space for vegetation is not formed in advance, but when trying to improve such a problem later, It is necessary to dig out a block that has already been laid and to bury a laying block without a hollow space, which is very time-consuming.

  For example, by laying a block without a hollow space in the part that becomes the boundary line indicating the parking area for each vehicle in the parking lot, it is easy to visually recognize the boundary of each parking area, and at the same time, the boundary line It is possible to satisfactorily ensure walking and running performance in the block (block without hollow space), but when changing the parking area, as in the above, dig up the already laid block, On the contrary, it is necessary to replace the block without the hollow space with the block with the hollow space, which is troublesome in construction.

  Moreover, not only in a parking lot, there is a case where decorativeness as the entire region is expressed by interspersing blocks without hollow spaces in a region where blocks having hollow spaces are arranged. In this case, if the arrangement of the block with the hollow space and the block without the hollow space are changed and the design of the entire area is changed, as in the case of the parking lot division change described above, a great effort is required for the construction. Cost.

  As described above, the labor for replacing the laying block becomes more remarkable in the case of an interlocking block in which two or more laying blocks are arranged adjacent to each other.

  That is, since each interlocking block has a design in which the contours mesh with each other by contacting each other, there is a possibility of adversely affecting the neighboring adjacent interlocking blocks when trying to dig one up, Eventually, the block must be replaced over a wide area, which increases the labor of construction.

  The present invention has been made in view of the above circumstances, and even if it has a hollow space for vegetation on a part of its surface, a laying block that can easily improve walking performance and running performance, and An object is to provide a detachable tool used for such a laying block.

  The laying block according to the present invention includes a detachable closing member that closes a vegetation hollow space formed on a part of the surface thereof, and under a situation where priority is given to vegetation, vegetation is applied to the hollow space. Under the circumstances where priority is given to walking and running, the hollow space is closed with a detachable closing member so that vegetation priority or walking / running priority can be easily switched.

  That is, the laying block according to the present invention is a laying block formed of concrete and having a vegetation hollow space on a part of its surface, and the upper surface of the laying block closes the hollow space at the same height as the surface. A detachable closing member having strength against a predetermined load loaded from above is provided.

  Here, the hollow space for vegetation may be one that penetrates to the lower surface of the block main body (portion other than the hollow space) (the hollow space becomes a through hole), or the block main body (hollow What does not penetrate to the lower surface of the portion other than the space (having a bottom portion, that is, the hollow space is formed as a recess) may be used.

  According to the laying block according to the present invention configured as described above, the blocking member having strength against a predetermined load loaded from above closes the hollow space for vegetation, thereby improving walking performance and running performance. Can do.

  In other words, if you step on the space occupied by vegetation (the hollow space when vegetation is removed) when walking, the toes and heels sink and the walking ability is poor, and the soil under the lawn is mud. May adhere to shoes, etc., but since the blocking member blocks this hollow space, the toes and heels will step on the upper surface of the blocking member without walking through the hollow space during walking. Since the member has strength against a predetermined load applied from above, wheels such as toes, heels, and strollers that step on the upper surface of the closing member are supported by the closing member, and the concrete molded portion other than the hollow space Like when stepping on, it does not sink downward.

  Accordingly, it is possible to improve the walking performance of pedestrians and the traveling performance of strollers, wheelchairs, and the like.

  Furthermore, when the blocking member is set in the hollow space of the laying block, the upper surface (the surface that can be directly stepped on with feet or wheels) is positioned at the same height as the surface that is a concrete molding portion other than the hollow space. Further, it becomes difficult for pedestrians' feet, stroller wheels, and the like to come into contact with the outer edge of the upper surface of the blocking member, thereby preventing tripping.

  And since this closing member is detachable (detachable) from the hollow space, at the portion that becomes the boundary line indicating the parking section, the walking space and the running performance are improved by closing the hollow space with this closing member. In other parts, the greening rate can be improved with the blocking member removed from the hollow space. In addition, when changing the layout of the boundary lines, etc., it is only necessary to attach and detach the blocking member. Since it is good, it is not necessary to dig up and replace the entire laying block as in the prior art, so that the labor of construction can be greatly reduced, and the construction period can be shortened and the construction cost can be reduced.

  In general, when constructing a laying block in a parking lot, erection stone is used as the boundary line indicating the parking area. However, erection block corresponding to the part that meets erection stone (the part occupied by erection stone) The part of was cut at the construction site.

  On the other hand, by using the laying block of the present invention in a state where the hollow space is blocked by the blocking member for this boundary line, the cutting work at the construction site becomes unnecessary, and also in this respect, the construction labor is reduced. Can be reduced.

  In addition, the strength against the load applied from above, which should be possessed by the closure member, is such that when the weight of a human adult human being of a general size is applied from above, it does not bend or breaks or collapses. It is sufficient that the strength is as low as possible, and it is not required to have the same strength as that of the concrete molding portion (block body portion) other than the hollow space.

  In other words, it is sufficient if the foot, the wheel of a baby stroller on which an infant rides, or the wheel of a wheelchair on which an adult rides are on the upper surface of the closing member so that the closing member does not easily deform. .

  In the laying block according to the present invention, it is preferable that the closing member is an embedded member embedded in the hollow space.

  According to the laying block according to the present invention having such a preferable configuration, when a vegetation such as lawn is formed in the hollow space for vegetation, the empty space is removed by removing the lawn from the hollow space. A hollow space can be closed by filling a buried member (may be a solid lump or a hollow member).

  At this time, since the buried member is filled up to the depth position (bottom position) of the hollow space where vegetation such as lawn has been applied, the upper surface of the buried member after being buried in the hollow space is buried. Even when stepped on with a foot, since the embedded member is in contact with the bottom of the hollow space, a stable hardness (a firm feeling) can be given as a feeling of stepping on.

  In addition, even if the hollow space penetrates to the lower surface of the laying block, the buried member is placed on the foundation (for example, the sand layer and the roadbed) on which the lower surface of the concrete molding portion other than the hollow space is placed. Therefore, the above-mentioned hardness feeling can be ensured.

  In the laying block according to the present invention, the buried member block body is preferable.

  Various materials such as concrete, brick, stone, wood and resin can be applied as the material of the block body.

  According to the laying block according to the present invention having such a preferable configuration, it is easy to ensure the strength of the embedded member itself.

  In addition, in the case where concrete is applied as the material of the block body, the material is the same as the concrete molding part (block body part) other than the hollow space, so that the blocking member (buried member) and the part other than the hollow space (concrete body part) It is possible to obtain an effect that makes it feel as a whole.

  In addition, in the case where the buried member is a concrete block body, a brick block body or a stone block body, the existing concrete block body, brick block body and stone made body used for other purposes etc. Of various block bodies such as block bodies, it is possible to select a block body having substantially the same contour shape as the hollow space of the laying block main body part. Therefore, by diverting such a block body, it is newly embedded. The manufacturing cost can be reduced compared to manufacturing the member.

  In the laying block according to the present invention, the block body is preferably a block having water permeability or water retention.

  According to the laying block according to the present invention having such a preferable configuration, since the block body as the burying member has water permeability, rainwater or the like is infiltrated into the water permeable block as the burying member so as to be below the laying block. Water can be drained, and water drainage can be improved.

  Therefore, it is possible to prevent a puddle from being formed by rainwater or the like on the surface (road surface) of the region where the laying block is laid, and as a result, water splashing on the upper surface of the buried member can also be reduced.

  Moreover, when the block body which is an embedded member is a water retaining block, the temperature can be lowered by the latent heat (heat of vaporization) when the retained water evaporates and the heat island phenomenon is alleviated as a result. Can also be a source of water for vegetation (eg, lawn, etc.) and can improve plant growth.

  In addition, concrete, a brick, etc. are applicable as a raw material of the block body which has water permeability or water retention.

  In the laying block according to the present invention, it is preferable that the embedded member includes a light emitting portion on an upper surface portion thereof.

  According to the laying block according to the present invention having such a preferable configuration, the light emitting portion provided on the upper surface of the embedded member emits light, so that it is a guide light embedded in the road surface even in a dark place such as at night. Function can be demonstrated.

  Therefore, for example, by embedding such an embedded member with a light emitting part in an area where a pedestrian walks, the light emitted from the light emitting part can be emitted to the driver of the vehicle or the By making a person visually recognize, a pedestrian area, its width, and the like can be accurately recognized.

  In addition, for each region that is desired to be distinguished, it is possible to make the distinction of the region visible by color coding by making the emission color of the light emitting unit different.

  In addition, the light emission part in this invention may use what is called an illuminating member like a light bulb, LED, etc. which light-emits when electric power, such as a battery, is supplied, and ambient light, such as daytime sunlight. A light storage member that stores light and obtains light emission by the light storage may be used.

  As the phosphorescent member, it is preferable to apply a material obtained by kneading and solidifying a phosphorescent material into concrete, and the light emitting part having a structure in which the phosphorescent member having a preferable structure is laminated on the upper surface of the embedded member is used for running and walking of a vehicle. Even if the surface layer wears over time due to walking of a person, etc., light emission can be secured over a long period of time, and durability is greatly improved compared to the case where a phosphorescent material is simply applied to the upper surface of the embedded member Can be made.

  In addition, when the phosphorescent member itself becomes worn and sufficient light emission cannot be obtained, the light emission of the light emitting portion can be easily recovered by replacing the embedded member including the phosphorescent member.

  In addition, in the thing using the lighting member that emits light by supplying power as the light emitting unit, the light emitting unit is continuously turned on, intermittently blinked, or turned off, etc. It is also possible to distinguish the areas.

  In addition, the area where the laying block of the present invention is laid is not limited to the parking lot described above, and can be laid in a plaza or the like. Therefore, according to the laying block laid in such a place, the light emission of the light emitting unit Depending on the difference in pattern and emission color, it is also possible to obtain the effect of producing an illumination.

  In the laying block according to the present invention, the embedded member has an embedded member main body portion formed at a height lower than the depth of the hollow space, and the height of the embedded member main body portion from the depth of the hollow space. The embedded member auxiliary portion is formed at a height that is subtracted and is embedded in a space below the embedded member main body portion of the hollow space, and the embedded member main body portion and the embedded member auxiliary portion are separate from each other. It is preferably a body member.

  Thus, according to the laying block according to the present invention having a preferable configuration, the embedded member is composed of two parts of the embedded member main body portion and the embedded member auxiliary portion, and does not need to be formed as a single one. For example, when there is an existing block or the like having substantially the same contour shape as the embedded member main body part, it is sufficiently considered that a difference occurs between the height of the hollow space and the height of the existing block, In that case, by preparing an embedded member auxiliary portion having a height corresponding to the difference between the height of the hollow space and the height of the existing block, the existing block or the like is used as the embedded member main body portion. By overlapping the main body portion with the embedded member auxiliary portion and closing the hollow space, the existing block or the like can be used effectively, and the manufacturing cost of the embedded member can be reduced.

  In the laying block according to the present invention, a joint having a predetermined width is formed between a surface defining the hollow space and an outer peripheral surface of the embedded member in a state where the embedded member is embedded in the hollow space. In the vicinity of the upper surface of the outer peripheral surface of the embedded member, it is preferable that an engaging portion is formed on which a tip of a detachable tool inserted into the joint is hooked.

  According to the laying block according to the present invention having such a preferable configuration, when the removal tool is inserted into a joint having a predetermined width formed between the surface defining the hollow space and the outer peripheral surface of the embedded member. The tip of the detachable tool can be hooked on the engaging portion formed in the vicinity of the upper surface of the outer peripheral surface of the embedded member, so that the embedded member is hollowed as the detachable tool is pulled out from the joint. It can be pulled out of the space and easily separated from the laying block main body (concrete forming portion).

  In the laying block according to the present invention, in the state where the embedded member is embedded in the hollow space, the width of the joint formed between the surface defining the hollow space and the outer peripheral surface of the embedded member, It is preferable that a joint width adjusting member that holds the joint substantially uniformly over the entire circumference of the joint is provided.

  According to the laying block of the present invention having such a preferable configuration, the joint width adjusting member provided between the surface defining the hollow space and the outer peripheral surface of the embedded member defines the surface defining these hollow spaces. The joint width formed between the outer peripheral surface of the embedded member and the outer peripheral surface of the embedded member can be maintained substantially evenly over the entire periphery of the joint (the entire outer periphery of the upper surface of the embedded member).

  In the laying block according to the present invention, the joint width adjusting member includes a first linear portion that extends in the vertical direction and contacts a surface that defines the hollow space, and extends in the vertical direction in the joint. It is preferable that the elastic member has a substantially U-shaped cross section including a second straight portion in contact with the outer peripheral surface, and a curved portion in which the first straight portion and the second straight portion are connected at their lower portions.

  Thus, according to the laying block according to the present invention having a preferable configuration, the joint width adjusting member formed of an elastic member having a substantially U-shaped cross section is the first straight portion (extending vertically in the U shape) of the U shape. One of the two portions) is in contact with the surface defining the hollow space, while the second straight portion (the other of the two U-shaped longitudinal portions) is in contact with the outer peripheral surface of the embedded member. Therefore, as the joint width becomes narrower, the elastic force generated at the U-shaped curved portion (the portion where the first straight portion and the second straight portion are connected to each other) becomes stronger.

  And the joint force adjusting member of the elastic member having the substantially U-shaped cross section described above is installed at a plurality of locations in the entire circumference of the joint, so that the elastic force generated in the curved portions in all the joint width adjusting members is substantially reduced. The joint width is automatically adjusted to be uniform.

  In addition, the above-described elastic member having a substantially U-shaped cross section is relatively inexpensive and can be easily formed, and thus has high practical utility.

The illustrated laying block 10 is made of concrete as shown in FIG. 2B, and a block main body portion 20 (having a vegetation hollow space 26 penetrating from the upper surface 21 to the lower surface 22 in a part of the surface thereof. (Corresponding to the entire conventional laying block) and the upper surface 31 closes the hollow space 26 at the substantially same height as the upper surface 21 of the block main body 20 and loads from above as shown in FIG. It is the structure provided with the closure member 30 which has the intensity | strength with respect to a predetermined load, and can be attached or detached with respect to the block main-body part 20. As shown in FIG.

  Here, although the laying block 10 of this embodiment is an interlocking block in which two or more are arranged adjacent to each other, the laying block of the present invention is not limited to the interlocking block.

  The hollow space 26 formed in the block main body 20 has the effect of increasing the greening rate of the area where the laying block 10 is laid by vegetation such as lawn.

  The block body 20 includes a relatively inexpensive base layer 20b and a decorative layer 20a formed on the base layer 20b. The top surface 21 of the decorative layer 20a has a width W of 2 to 6 [mm]. The plurality of grooves 24 are formed in parallel at equal intervals P of 6 to 15 [mm].

  The cross-sectional contour shape of the groove 24 may be substantially V-shaped, U-shaped, U-shaped with a sharp corner, or an inverted M-shape. It may be any shape.

  In addition, even if the block main body part 20 consists only of the base layer 20b which does not have the decorative layer 20a, it is preferable to form the said groove | channel 24 in the upper surface.

  As will be described later, the groove 24 has the effect of reducing vibrations when passing through joints formed with other adjacent laying blocks 10 in addition to the effect of preventing slippage. When only the utility as an anti-slip is obtained, the interval P between the grooves 24 does not need to be equal.

  Further, on the upper surface 21 of the block main body portion 20, linear groove portions 25, 25 extending from the inner peripheral surface 26 a defining the hollow space 26 to the outer peripheral surface 23 of the block main body portion 20 are formed. , 25 are traces of a support rod that suspends the core for forming the hollow space 26 of the block body 20.

  Further, the embedded member 30 has water permeability, and even if rainwater or the like falls on the laying block 10 in a state of being embedded in the hollow space 26, the rainwater or the like immediately permeates the embedded member 30, Rainwater or the like does not accumulate on the upper surface 31, and even in the case of a large amount of rain, the rainwater or the like passes through the embedded member 30 and is shown in FIG. 2A (a cross-sectional view taken along the line AA in FIG. ), The water is drained to the foundation 100 (laying sand layer 100a and the roadbed 100b) on which the laying block 10 is laid, and the water drainage can be improved, and the water splash on the upper surface 31 of the buried member 30 is also possible. Can be reduced.

  In the laying block 10 (the state of only the block main body portion 20) in which the embedded member 30 is not embedded in the hollow space 26 of the block main body portion 10, rainwater or the like is drained to the foundation 100 through the hollow space 26. The

  2A, reference numeral 110 denotes the upper surface of the foundation 100, that is, the upper surface of the laying sand layer 100a, and reference numeral 200 denotes the upper surface of the laying block 200 (the upper surface 21 of the block main body 20 and the upper surface 31 of the burying member 30). Is the road surface.

  Here, the embedded member 30 has a height h0 of the hollow space 26 of the block main body 20 (the hollow space 26 of the present embodiment is formed to penetrate from the upper surface 21 to the lower surface 22 of the block main body 20). Therefore, the height h0 is substantially equal to the height of the block main body portion 20). However, the height h0 is formed as a single piece with the height h0. Not necessarily.

  For example, as shown in FIG. 4, the embedded member 30 includes an embedded member main body portion 38 formed at a height h2 (<h0) lower than the height h0 of the hollow space (26), and the hollow space (26). A space formed by a height h1 (= h0−h2 <h0) obtained by subtracting the height h2 of the embedded member main body portion 38 from the height h0, and a space below the embedded member main body portion 38 in the hollow space (26). The embedded member main portion 38 and the embedded member auxiliary portion 37 may be formed of separate members.

  As described above, the embedded member 30 is constituted by two parts of the embedded member main body portion 38 having the height h2 and the embedded member auxiliary portion 37 having the height h1, and is not configured as a single member having the height h0. For example, an existing block (height h <b> 2) having substantially the same contour shape as the embedded member main body portion 38 can be used as the embedded member 30.

  In this case, a height difference Δh (= h0−h2) occurs between the height h0 of the hollow space 26 and the height h2 of the existing block or the like. In this case, the height h0 of the hollow space and its height By preparing the buried member auxiliary portion 37 having a height corresponding to the difference Δh from the height h2 of the existing block or the like, the existing block or the like is used as the buried member main body portion 38, and this buried member main body portion 38 is buried. By overlapping the member auxiliary portion 37 and closing the hollow space 26, an existing block or the like can be used effectively, and the manufacturing cost of the embedded member 30 can be reduced.

  That is, when there are a plurality of types of the laying blocks 10 having different heights h0 of the hollow spaces 26, the laying blocks 10 corresponding to the laying blocks 10 having the different heights h0 are buried correspondingly. The preparation of the member 30 may be costly in view of the cost of the mold for manufacturing.

  However, the embedded member 30 is configured by the embedded member main body portion 38 which is an existing block or the like having a constant height h2, and a plurality of types of embedded member auxiliary portions 37 having different heights h1, so that the existing block or the like can be used. While it can be used for the laying block 10 of various heights, preparing many types of buried member auxiliary portions 37 with different heights is more than preparing many types of single buried members 30 with different heights. Therefore, the manufacturing cost can be reduced for the entire embedded member 30.

  In addition, the laying block 10 is arranged between the inner peripheral surface 26 a that defines the hollow space 26 and the outer peripheral surface 35 of the embedded member 30 in a state where the embedded member 30 is embedded in the hollow space 26 of the block body 20. A joint 60 (see FIG. 1A) having a predetermined width is formed, and a removal tool 500 (see FIG. 11 described later) inserted into the joint 60 in the vicinity of the upper surface 31 of the outer peripheral surface 35 of the embedded member 30. Engagement grooves 33 (engagement portions) on which the front ends 511, 511 of the outer periphery 35 are hooked are formed over the entire circumference of the outer peripheral surface 35, and the detachment tool 500 is used to attach the embedded member 30 to the block main body portion 20. It can be easily pulled out from the hollow space 26 and separated from the block main body 20.

  Further, the laying block 10 includes an inner peripheral surface 26 a that defines the hollow space 26 and an outer peripheral surface of the embedded member 30, as shown in FIG. 2B, with the embedded member 30 embedded in the hollow space 26. 35 is provided with a joint width adjusting member 50 that holds the joint 60 formed substantially uniformly over the entire circumference of the joint 60. 26, the width of the joint 60 formed between the inner peripheral surface 26a defining the inner surface 26 and the outer peripheral surface 35 of the embedded member 30 can be kept uniform.

  The joint width adjusting member 50 in the present embodiment is specifically an elastic member having a substantially U-shaped cross section, and extends in the vertical direction in the joint 60 to define the hollow space 26. A first straight part 51 that contacts the outer peripheral surface 35 of the embedded member 30, and a curved part 53 that connects the first straight part 51 and the second straight part 52 at their lower part. It consists of.

  When the width of the joint 60 is relatively narrow, the joint width adjusting member 50 has a relatively strong elastic force generated in the curved portion 53. Therefore, the first straight line is set so that the joint 60 has a relatively wide width. The space | interval of the part 51 and the 2nd linear part 52 is expanded, and the width | variety of a joint can be adjusted by this.

  The joint width adjusting member 50 is disposed on a pair of opposite sides of the entire circumference of the joint 60 with the embedded member 30 interposed therebetween, so that the joint 60 on one side has a relative width. Since the width of the joint 60 on the opposite side is relatively narrow, the first straight portion 51 and the first linear portion 51 are arranged so that the width of the joint 60 on the opposite side is relatively wide due to the above-described action. Since the space between the straight line portions 52 is widened, the widths of the pair of joints 60 and 60 on the opposite sides are adjusted uniformly.

  In the laying block 10 of the present embodiment, it is preferable that the same number of joint width adjusting members 50 are arranged on a pair of sides that are opposite to each other among the four sides of joints 60.

  That is, for example, as shown in FIG. 3A, when joint width adjusting members 50 are provided at positions P1 and P2 on one side of a pair of two sides that are opposite to each other (two pieces per side). The configuration in which the joint width adjusting member 50 is provided) is also provided with joint width adjusting members 50 at positions P3 and P4 respectively facing the positions P1 and P2 on the other side, and another set of two sides. When joint width adjusting members 50 are provided at positions P5 and P6 on one side (a configuration in which two joint width adjusting members 50 are provided on one side), the positions P5 and P6 are also provided on the other side. It is preferable to provide joint width adjusting members 50 at positions P7 and P8 that face each other.

  In this way, by placing the same number of joint width adjusting members 50 on each pair of opposite sides, the joint width adjusting members 50 act on the embedded member 30 in opposite directions (elastic force). Becomes uniform, and the widths of the joints 60 are easily aligned.

  Further, by providing two joint width adjusting members 50 on each side, the width of the joint 60 in one side can be made uniform. That is, the outer peripheral surface 35 of the embedded member 30 is restrained from being inclined with respect to the inner peripheral surface 26a of the block main body portion 20, so Can be held in parallel.

  As shown in FIG. 3B, when one joint width adjusting member 50 is provided at the position P9 (substantially the center of one side) of one side of a pair of opposite sides, the other side Also, one joint width adjusting member 50 is provided at a position P10 (substantially the center of the side) opposite to the position P9, and one of the other two sides is set at positions P5 and P6, respectively. When the joint width adjusting member 50 is provided (a configuration in which two joint width adjusting members 50 are provided on one side), the joint width is adjusted at positions P7 and P8 facing the positions P5 and P6, respectively, on the other side. Each member 50 may be provided.

  As described above, the joint width adjusting member 50 is provided for only two sides of a pair of sides (a total of four sides) that are opposite to each other, and the other two sides of the other pair are arranged. Even if the joint width adjusting members 50 are arranged one by one, the outer peripheral surface 35 of the embedded member 30 can be prevented from being inclined with respect to the inner peripheral surface 26 a of the block main body 20.

  In addition, as shown in FIGS. 3 (a) and 3 (b), the arrangement position when arranging the two joint width adjusting members 50 on one side is a position close to both ends of the side. From the viewpoint of the effect of suppressing the tilt, it is preferable.

  As shown in FIG. 3 (c), when one joint width adjusting member 50 is provided at the position P9 (approximately the center of the side) of one side of a pair of opposite sides, the other side In addition, one joint width adjusting member 50 is provided at a position P10 (approximately the center of the side) facing the position P9, and one side position P11 (approximately the center of the side) of the other two sides. When one joint width adjusting member 50 is provided, the other joint width adjusting member 50 may be provided at the position P12 (substantially the center of the side) opposite to the position P11.

  In the laying block of the present embodiment, since the hollow space 26 and the burying member 30 that closes the hollow space 26 are both substantially rectangular in plan view, the two sides facing each other are clearly identified. When the hollow space 26 and the embedded member 30 are circular in plan view, the joint width adjusting member 50 may be disposed at three or more positions on the circumference of the circle. In this case, the joint width adjusting member 50 is The angles around the center of the circle are equally spaced (in the case of three joint width adjusting members 50, the angular spacing is 120 °, in the case of four joint width adjusting members 50, the angular spacing is 90 °, and five joint width adjusting members. In the case of 50, the angular interval is 72 °, and in the case of the six joint width adjusting members 50, the angular interval is 60 °. Is preferable for equalizing.

  Further, when the hollow space 26 and the embedded member 30 are pentagonal in plan view, the joint width adjusting members 50 may be arranged on joints 60 corresponding to the sides of the pentagon, and are hexagonal in plan view. In this case, joint width adjusting members 50 may be arranged on joints 60 corresponding to the respective sides of the hexagon, or joint width adjusting members 50 only on joints 60 corresponding to three sides adjacent to adjacent sides. May be arranged.

  Since the joint width adjusting member 50 in the present embodiment is an elastic member having a substantially U-shaped cross section as described above, it can be easily formed at a relatively low cost and has high practical utility.

  Further, in the joint width adjusting member 50, a convex portion 52 a that engages with the engaging groove 33 formed on the outer peripheral surface 35 of the embedded member 30 is formed on the second linear portion 52 that contacts the outer peripheral surface 35 of the embedded member 30. In the state where the joint width adjusting member 50 is disposed on the joint 60, the projecting portion 52 a engages with the engaging groove 33 in a state of protruding into the engaging groove 33 of the embedded member 3. Can be prevented from falling off easily.

  Next, the effect | action of the laying block 10 of this embodiment is demonstrated.

  First, as shown in FIG. 5 (a) and FIG. 5 (b) showing a cross section along the line A'-A ', the laying block 10 is in a state where the embedded member 30 is removed (the block main body portion 20). ), The hollow space 26 is filled with the soil 29b and the vegetation 29 made of the lawn 29a rooted in the soil 29b, and laid on the upper surface 110 of the foundation 100.

  Here, as shown in the plan view of FIG. 6, this laying block 10 is an interlocking block and is in a state in which its outer peripheral surface 23 is in contact with a plurality of other laying blocks 10, 10,. The upper surface 21 of these laying blocks 10 (block body 20) is, for example, a road surface 200 in an area 300 such as a parking lot where the vehicle 400 is parked as shown in FIG. 7 (FIG. 5B). It becomes.

  At this time, as described above, the laying block 10 of the present embodiment has a portion of the outer peripheral surface 23 of each laying block 10 in a state where two or more laying blocks 10, 10,. The space region 40 (see FIG. 6) having a substantially rectangular outline surrounded by the square has substantially the same outline shape as the hollow space 26 of each laying block 10.

  The soil 29b and the lawn rooted in the soil 29b are also formed in the space region 40 formed by being surrounded by the outer peripheral surfaces 23, 23, 23, 23 of the four laying blocks 10, 10, 10, 10. Vegetation 29 made of 29 a is filled and laid on the upper surface 110 of the sand layer 100 a of the foundation 100.

  According to the laying block 10 configured as described above, the hollow space 26 and the four laying blocks 10 included in each laying block 10 are supported while the wheel load of the vehicle 400 is supported by the road surface 200 that is the upper surface 21 of the block main body 20. Since the newly formed space regions (new hollow spaces) 40 surrounded by the vegetation 29 are respectively provided to the vegetation 29, the area ratio of greening can be increased.

  Although not shown in FIGS. 6 and 7, the vehicle 400 slips because the groove 24 is formed on the upper surface 21 of the block main body portion 20 that becomes the road surface 200 as shown in FIG. 5. Can be prevented.

  In this case, in order to enhance the slip prevention effect, the laying block 10 is arranged so that the extending direction of the groove 24 is parallel to the direction perpendicular to the Y direction as the traveling direction of the vehicle, that is, the X direction. It is effective.

  Next, a case where a partition line (boundary line) representing, for example, a parking section for each vehicle is displayed on the laying block 10 in the area 300 illustrated in FIG. 7 will be described.

  First, the lawn 29a and soil 29b vegetated in the hollow space 26 are dug out for the laying block 10 to be used as a lane marking.

  Further, in the laying block 10 of the present embodiment, the space region 40 having a substantially rectangular outline surrounded by a part of the outer peripheral surface 23 of each laying block 10 is substantially the same as the hollow space 26 of each laying block 10. Since it has an outline shape, the vegetation 29 filled in the space area 40 (see FIG. 8) existing between the laying blocks 10 and 10 to be used as the dividing lines is also excavated, and the space area 40 The (new hollow space 40) is also a hollow space.

  Next, the above-described embedded members 30 are embedded in these hollow spaces 26 and 40, respectively (FIG. 8). As shown in FIG. 9, by performing this operation on all laying blocks 10 to be used as lane markings and between the laying blocks 10, a greening region 320 (region where vegetation is performed) of the region 300 Can be switched to the area 310 of the lane marking in which the vegetation 29 is not performed.

  The embedded member 30 embedded in the hollow space 26 of the block main body 20 is a detachable member that can be easily detached from the hollow space 26 by using a predetermined detaching tool. The presence or absence of the vegetation 29 can be easily switched according to the attachment / detachment of the member 30.

  Further, the lane marking area 310 indicating the parking section is not filled with the soft vegetation 29 in the hollow space 26, that is, the embedded member 30 embedded in the hollow space 26 has a strength against a predetermined load applied from above. Therefore, even if a walking pedestrian steps on the upper surface 31 of the embedded member 30 or a wheel such as a stroller or a front wheel of a wheelchair passes through the upper surface 31 of the embedded member 30, these walking A person's foot or a wheel such as a baby stroller is supported by the embedded member 30 and does not sink downward as when the upper surface 21 of the block main body 20 (concrete molding portion) is stepped on.

  Accordingly, it is possible to improve the walking performance of pedestrians and the traveling performance of strollers, wheelchairs, and the like.

  Furthermore, in the state where the embedded member 30 is set in the hollow space 26 of the laying block 10, the upper surface 31 thereof is at the same height as the upper surface 21 of the block main body 20 that is a concrete molding portion other than the hollow space 26. Therefore, the pedestrian's foot, the stroller wheel, and the like are not easily caught on the outer edge of the upper surface 31 of the embedded member 30 or the opening edge of the hollow space 26 in the block main body 20, thereby preventing tripping and the like. it can.

  And since this burying member 30 is detachable (detachable) from the hollow space 26, in the region 310 that becomes a lane marking indicating the parking section, the embedment member 30 closes the hollow space 26 with the buoyancy and In the area 320 other than that, the greening rate can be improved by the vegetation 29 in a state where the embedded member 30 is removed from the hollow space 26, and the layout of the lane markings and the like is changed. In this case, it is only necessary to attach and detach the embedded member 30, so that it is not necessary to dig up the entire laying block 10 and replace it with another type of laying block in which the hollow space 26 is not formed, The labor of construction can be greatly reduced, and the construction period can be shortened and construction costs can be reduced.

  In addition, when the pedestrian is used for traffic, the width of the lane marking area 310 is sufficient for one row of the laying block 10 (see FIG. 9). Therefore, it is preferable to set the width of the lane marking area 310 as wide as about three rows of the laying blocks 10 as shown in FIG.

  The laying block 10 of the present embodiment can change the appearance of the entire region 300 by changing the distribution of the presence or absence of the vegetation 29 as well as the purpose of improving the walking ability and the trafficability. When the purpose is only to obtain an effect, it is not necessary to make the embedded member 30 provided in the spatially continuous laying blocks 10 among the laying blocks 10 arranged. In the region 300, the laying blocks 10 provided with the burying member 30 may be scattered (a state where they are spatially discretely arranged).

  Although not shown in FIGS. 8, 9, and 10, the grooves 34 are formed not only on the upper surface 21 of the block main body 20 serving as the road surface 200 but also on the upper surface 31 of the embedded member 30 as shown in FIG. 1. Therefore, it is possible to prevent a pedestrian or the like from slipping when walking. In this case, embedding the embedded member 30 so that the extending direction of the groove 34 is in the same direction as the groove 24, that is, parallel to the X direction, is effective in enhancing the slip prevention effect.

  Further, the grooves 24 and 34 formed in the laying block 10 have an equal interval of 6 to 15 [mm], so that the upper surface 21 (surface) of the block main body 20 and the upper surface 31 of the embedded member 30 are obtained. The wheel of a stroller or wheelchair that travels at a constant speed is subjected to vibrations of a constant frequency from the grooves 24 and 34, so that the wheel of the stroller or the like can be used as a joint between adjacent laying blocks 10 or a block main body portion 20. The impact (vibration and sound) received when passing through the joint 60 between the embedment member 30 and the embedded member 30 can be reduced.

  As described above, according to the laying block 10 of the present embodiment, it is possible to easily switch between improving the walking performance and running performance or increasing the vegetation 29 by attaching and detaching the embedded member 30.

  Further, in the laying block 10 of the present embodiment, the embedded member 30 has a depth position (bottom position) where the vegetation 26 such as lawn is applied in the hollow space 26. In the present embodiment, on the upper surface 110 of the foundation 100. Since the buried member 30 is in contact with the bottom of the hollow space 26 even when the upper surface 31 of the buried member 30 after being buried in the hollow space 26 is stepped on with a foot, As a stepping feel, it can give a stable hardness (solid feeling).

  Even if the hollow space 26 is a laying block that does not penetrate to the lower surface 22 of the laying block 10, the same actions and effects as those of the laying block 10 of the above-described embodiment can be obtained.

Further, the embedded member 30 is not limited to a concrete member, and may be formed of brick or stone, and by a laying block having the embedded member 30 formed of such brick or stone. In addition, the same actions and effects as those of the laying block 10 having the concrete burying member 30 described above can be obtained.
(Embodiment 2: Desorption tool)
FIG. 11 shows an example of a detachable tool 500 used for detaching the embedded member 30 from the laying block 10 of the present embodiment. The detachable tool 500 is an embodiment of a detachable tool according to the present invention. It is.

  The detaching tool 500 has a structure in which two gripping arms 510 and 510 pivotally supported in a hinge shape are provided below a cylindrical or columnar hand-held portion 520, and the two gripping arms 510 and 510 are respectively provided. In this configuration, the shaft C1 is independently rotated about the rotation center in the direction indicated by the arrow.

  The rotating outer end portions of the gripping arms 510 and 510 are bent in the circumferential direction to form the peripheral walls 511 and 511, and the tip portions 512 and 512 are folded back and formed in a hook shape.

  Then, as shown in FIG. 12, by using this detaching tool 500, the burying member 30 of the laying block 10 according to the above-described embodiment is pulled out from the hollow space 26 of the block main body portion 20 and from the block main body portion 20. Can be withdrawn.

  That is, as shown in FIGS. 12 (a) and 12 (b), the detachment tool 500 is inserted into the holding arm 510 from above the laying block 10 with the burying member 30 embedded in the hollow space 26 of the block body 20. , 510 and the peripheral walls 511, 511 are lowered so as to be inserted into the joint 60.

  At the time of the lowering, the gripping arms 510 and 510 are each rotated about the axis C1 by their own weights and try to hang down in the vertical direction, but are attached and detached so that the gripping arms 510 and 510 do not hang down. A user or the like of the tool 500 lowers both holding arms 510 and 510 while keeping them horizontal.

  Then, as shown in FIGS. 7C and 7D, when the tip portions 512 and 512 of the detaching tool 500 are inserted into the joint 60, both the gripping arms 510 and 510 rotate slightly around the axis C1 by their own weight. As a result, the hook-shaped tip portions 512 and 512 of the gripping arms 510 and 510 are in a state of entering into the engagement grooves 33 formed in the vicinity of the upper surface 31 of the embedded member 30.

  When the removal tool 500 is lifted upward in the state where the leading ends 512 and 512 of the removal tool 500 are respectively inserted into the engagement grooves 33 of the embedded member 300 (FIGS. 12C and 12D) (FIG. 12E). , (F)), the both end arms 510 and 510 are pulled up while being rotated so as to hang downward about the axis C1 due to their own weights, and at this time, the tip that has entered the engaging groove 33 of the embedded member 30 The parts 512 and 512 are caught in the engaging groove 33.

  As a result, the weight of the embedded member 30 (the load in which the mass of the embedded member 30 acts downward due to gravity) acts on the distal end portions 512 and 512 of both gripping arms 510 and 510. The arms 510 and 510 are further rotated in the direction to hang down, and as a result, the load with which the removal tool 500 grips the embedded member 30 is increased.

  Therefore, when the user holds the hand-held portion 520 with his / her hand and pulls the removal tool 500 upward as shown in FIGS. 5E and 5F, the user is caught by the tip portions 512 and 512 of the removal tool 500. The embedded member 30 is lifted upward, detached from the hollow space 26 of the block main body 20, and finally separated from the block main body 20.

  On the contrary, when the operation of attaching the embedded member 30 to the hollow space 26 of the block main body portion 20 is performed, the procedure opposite to the above-described detachment operation may be performed.

  Thus, according to the removal tool 500 according to the present embodiment, the embedded member 30 can be easily detached from the hollow space 26.

  Further, the detaching tool 500 of the present embodiment hangs vertically downward when the two gripping arms 510 and 510 are rotated about the axis C1, respectively, and the two gripping arms 510 and 510 overlap each other. The thickness of the detachable tool 500 as a whole can be reduced to the thickness of the overlapping portion of the two gripping arms 510 and 510, and therefore the occupied space when storing the detachable tool 500 can be suppressed. it can.

  In addition, although the removal tool 500 of this embodiment has the two holding arms 510 and 510, the removal tool which concerns on this invention is not limited to this form, It is inserted in the joint 60 and the front-end | tip As long as the part 512 hooks the engaging groove 33 formed in the outer peripheral surface 35 of the embedded member 30 and lifts the embedded member 30 upward, the embedded member 30 can be separated from the hollow space 26. Form may be sufficient.

Moreover, the removal tool according to the present invention is not limited to the above-described embodiment, but is the shape of the embedded member 30 to be detached (circular, triangular, or quadrangular in plan view). It is possible to adopt various forms depending on the number of the engaging grooves 33 formed in the embedded member 30 and the position thereof.
(Embodiment 3; laying block having a buried member having a light emitting member)
FIG. 13 is a perspective view illustrating an embodiment in which an embedded member 70 having a configuration in which the light emitting portion 74 or the light emitting portion 75 is provided on the upper surface 71 is applied as the above-described embedded member 30. In addition, the code | symbol 73 in a figure is an engagement groove | channel equivalent to the engagement groove | channel 33 in the burying member 30 shown in FIG.

  Here, the light-emitting unit 74 shown in FIG. 13A uses a phosphorescent member that accumulates daytime sunlight and other environmental light and obtains light emission by the phosphorescence, and this phosphorescent member is phosphorescent in concrete. The material is kneaded and hardened.

  The light emitting unit 75 shown in FIG. 13B uses a so-called lighting member such as a light bulb or LED that emits light when power is supplied from a power source 77 such as a battery. A cover 76 made of a colorless transparent or colored transparent resin or the like is provided.

  In addition, it is good also as a structure which provides a solar cell panel in the inside covered with a part of this cover 76, or a cover, and uses the power supply 77 as a secondary battery.

  In addition, since these embedded members 70 have the same configuration and structure as those of the embedded member 30 shown in FIG. 1 or 4 except for the light emitting portions 74 and 75 described above, the embedded block having these embedded members 70 is provided. Also, the same operation and effect as the laying block of the above-described embodiment can be obtained.

  Furthermore, according to the laying block including the burying member 70 having the light-emitting portion 74 or the light-emitting portion 75, the light-emitting portion 74 or the light-emitting portion 75 provided on the upper surface 71 of the burying member 70 emits light. Even in a dark place, the function as a guide light embedded in the road surface can be exhibited.

  Therefore, for example, in a region where a pedestrian walks, by using such a laying block in which the burying member 70 with the light emitting portions 74 and 75 is embedded, the light emitting portion 74 can be used even in a situation where it is difficult to see the feet at night or the like. , 75 allows the driver or pedestrian of the vehicle to visually recognize the pedestrian area, its width, and the like.

  Further, by using a laying block having a difference in emission color from the light emitting units 74 and 75 for each area desired to be distinguished, the area distinction can be visually recognized by color coding. Moreover, since the light emitting portions 74 and 75 are provided in the detachable embedded member 70 among the laying blocks, the entire laying block is dug up and replaced every time the layout of the region to be classified by the emission color is changed. It is not necessary to do so, and the construction can be facilitated because the buried member 70 has only to be attached to and detached from the buried member 70 having the light emitting portions 74 and 75 of other emission colors.

  Moreover, since the light emission parts 74 and 75 are easily exchanged when the light emission parts 74 and 75 deteriorate over time due to running of a vehicle, walking of a pedestrian, etc., maintainability can also be improved.

  In addition, in what formed the light emission part 74 with the luminous member which kneaded the luminous material into the concrete, light emission by the luminous material can be ensured over a long period of time, and the luminous material is simply applied only to the upper surface 71 of the embedded member 70. Durability can be greatly improved compared with what was applied.

  In addition, when the phosphorescent member itself is worn out and sufficient light emission cannot be obtained, the light emission of the light emitting portion 74 can be easily recovered by detaching and replacing the embedded member 70 including the phosphorescent member. .

  On the other hand, a laying block having a light emitting unit 75 to which an illumination member that emits light by supplying power is applied has a lighting pattern in which the light emitting unit 75 is continuously turned on, intermittently blinked, or turned off. It is also possible to distinguish areas by the difference.

In addition, the area for laying such a laying block is not limited to the parking lot described above, and can be laid in a plaza or the like. Therefore, according to the laying block laid in such a place, the light emitting unit 75 Depending on the light emission pattern and the difference in the light emission colors of the light emitting portions 74 and 75, it is possible to obtain the effect of producing an illumination.

  At this time, the upper surface of the flat plate 81 is formed to be at a height position substantially coincident with the upper surface 21 of the block main body portion 20.

  And according to the laying block 10 of the embodiment configured in this way, the protrusions 84 and 84 formed on the lid member 80 are inserted into at least a part of the groove portions 25 and 25 of the block main body portion 20, By being placed on the bottoms of the grooves 25, 25, it is possible to prevent the lid member 80 from falling into the hollow space 26.

  And by covering the hollow space 26 with the lid member 80 in this way, it is possible to have strength against a predetermined load applied from above without digging out and removing the vegetation 29 of the hollow space 26, Even if a walking pedestrian steps on the flat plate portion 81 of the lid member 80, or a wheel of a stroller or the front wheel of a wheelchair passes through the upper surface of the flat plate portion 81 of the lid member 80, these The pedestrian's feet and wheels such as a baby stroller are supported by the lid member 80 and do not sink downward as when the upper surface 21 of the block main body 20 is stepped on.

  Accordingly, it is possible to improve the walking performance of pedestrians and the traveling performance of strollers, wheelchairs, and the like.

  Even in a state where the lid member 80 covers the upper part of the hollow space 26, rainwater and the like are supplied to the vegetation 29 through the many water drain holes 82 formed in the flat plate 81, so that the vegetation 29 grows. While maintaining the above, it is possible to improve walking performance and running performance.

  Further, by removing the lid member 80, the vegetation 29 of the hollow space 26 appears as it is, so that greening can be obtained.

  In addition, since the projections 84 and 84 of the lid member 80 are only placed in the grooves 25 and 25 of the block main body 80, the lid member 80 can be easily detached from the block main body 20, so It is possible to easily switch between improving traveling performance (in a state where the lid member 80 is covered) or giving priority to greening (in a state where the lid member is not covered).

  When the hollow space 26 is closed with the lid member 80, the leg 83 formed on the lower surface of the lid member 80 is inserted into the vegetation 29 (especially the soil 29b) in which the hollow space 26 is disposed. Therefore, it is possible to prevent the lid member 80 from being easily lifted or easily detached from the hollow space 26.
