Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 12 are for explaining this embodiment.

<Structure> The configuration will be described below.

The pavement block 2 and the pavement block 2 are used so that turf can be planted by arranging and laying a plurality of pavement blocks 2 as shown in FIGS. 1 (to 4) on the ground 1. Provide multiple laying patterns.

In this embodiment, the pavement block 2 is as follows.

(1) The paving block 2 includes a substantially rectangular parallelepiped body portion 11 and four shoulder portions 12 extending from both ends of the body portion 11 in the longitudinal direction 15 to both sides of the body portion 11 in the lateral direction 16. It is provided with a block body 14 having a substantially I-shaped plan view (condition 1).
The shoulder portion 12 has an upper surface 12b lower than the upper surface 11a of the body portion 11, and has an extension dimension f equal to each other in a direction orthogonal to the longitudinal direction 15 of the body portion 11 in a state of being flush with the end portion of the body portion 11. (Condition 2).
Further, each shoulder portion 12 is provided with an inclined portion 12a at a corner portion on the side surface thereof.
As shown in FIG. 2, the pavement block 2 has the dimension a of the body portion 11 in the longitudinal direction 15 and the dimension e of the body portion 11 in the lateral direction 16 and the extension dimensions f of the two shoulder portions 12 on both sides. The ratio to the added shoulder width dimension b is 2: 1 (a: b = 2: 1) (condition 3). For example, the dimension a of the body portion 11 in the longitudinal direction 15 is 300 mm, the shoulder width dimension b is 150 mm, and the like. However, the specific dimensions are not limited to the above.
The inner dimension d between the shoulders 12 provided at both ends of the body portion 11 in the longitudinal direction 15 is twice or more (d ≧ 2c or d> 2c) the dimension c of the width of the shoulder portion 12 in the longitudinal direction of the body portion. (Condition 4).
The inner dimension d between the shoulder portions 12 is equal to or greater than the shoulder width dimension b (d ≧ b or d> b) (condition 5).
Then, by arranging the pavement blocks 2 having these configurations in combination, five or more types of laying patterns are possible.

Here, in the pavement block 2, the longitudinal direction 15 of the body portion 11 becomes the longitudinal direction 15 of the pavement block 2 as it is, and the lateral direction 16 of the body portion 11 becomes the lateral direction 16 of the pavement block 2 as it is. There is. Further, the height direction of the body portion 11 and the shoulder portion 12 is the height direction or the thickness direction of the pavement block 2. The pavement block 2 may be made of concrete, resin, or metal, but in this embodiment, it is made of concrete.

By forming the body portion 11 into a rectangular parallelepiped shape, when the pavement blocks 2 are arranged on the ground 1, the body portions 11 can be made continuous with each other with substantially no gap. The upper surface 11a of the body portion 11 is formed with a rectangular decorative surface 11a that is one size smaller than the planar shape of the body portion 11. A shape adjusting portion 11b such as a slightly inclined step portion or a cornered portion that is continuous over the entire circumference is provided on the peripheral edge portion of the decorative surface 11a.

As described above, the four shoulder portions 12 are provided on the body portion 11 so as to have the same size and be symmetrical to each of the longitudinal direction 15 and the lateral direction 16 of the body portion 11.

Each shoulder portion 12 has a basic shape of a substantially square or rectangular shape in a plan view having a side portion provided so as to be flush with the end surface of the body portion 11. Further, a side bay portion 13 having a substantially concave shape in a plan view is provided by a side surface of the body portion 11 and two shoulder portions 12 provided at both ends of the body portion 11 in the longitudinal direction 15.

By making the shoulder portion 12 an upper surface 12b lower than the upper surface 11a of the body portion 11, when the pavement block 2 is laid on the ground 1, the entire shoulder portion 12 is hidden in the ground and the body portion 11 is decorated. The surface 11a is exposed from the ground 1. The upper surface 12b of the shoulder portion 12 is a gently inclined surface having a downward slope toward the outside in the lateral direction 16 of the pavement block 2. The inclination angle of this inclined surface is set to 10 ° or less (for example, about 7 °). The boundary portion 17 connecting the upper surface 12b of the shoulder portion 12 and the upper surface 11a of the body portion 11 is a curved surface having a relatively large radius of curvature or a polygonal shape similar to a curved surface, which is convex downward, and provides a stress relaxation portion. Is forming.

Each portion of the side surface of the pavement block 2 is provided with a plurality of ridge portions 18 extending in the height direction. The ridge portion 18 is provided to form a gap serving as a joint when the pavement blocks 2 are installed in combination, and to prevent the load from being transmitted to each other in a biased manner. It should be noted that the ridge portion 18 is installed in the longitudinal direction 15 or the lateral direction of the pavement block 2 so that the surfaces do not come into direct contact with each other or the width of the gap does not vary when the pavement blocks 2 are installed in combination. It is installed at intervals of 16.

Further, in the pavement block 2, in order to establish the above-mentioned plurality of types of laying patterns in a better state, the dimension e of the body portion 11 in the lateral direction 16 and the extension dimension f of the two shoulder portions 12 The ratio of is approximately 1: 1: 1 (f: e: f = 1: 1: 1).

Hereinafter, five specific types of laying patterns will be described in a two-dimensional view.

FIG. 5 shows a parallel pasting P1 which is one of the laying patterns. In this parallel pasting P1, a plurality of pavement blocks 2 are arranged in parallel and adjacent to each other with the ends of the body portions 11 aligned flush with each other in the lateral direction 16 of the block main body 14. In the longitudinal direction 15, the end portions of the body portion 11 and the shoulder portions 12 are butted against each other, and the body portions 11 are arranged adjacent to each other in a straight line. The parallel attachment P1 is a laying pattern in which the distance between the parallel body portions 11 is widest (= 2f) by abutting the tips of the shoulder portions 12 with each other.

FIG. 6 shows a staggered pasting P2, which is one of the laying patterns. In this shift pasting P2, the pavement block 2 is shifted in the longitudinal direction 15 in the lateral direction 16 of the block body 14, and the adjacent shoulder portion 12 enters the side bay portion 13 on the opposite side. The body portions 11 are arranged adjacent to each other in contact with the body portions 11, and the body portions 11 are arranged adjacent to each other in a straight line with the ends of the body portions 11 abutting each other in the longitudinal direction 15 of the block main body 14. This staggered sticking P2 is a modification of the parallel sticking P1, and is a laying pattern in which the distance between the parallel body portions 11 is the narrowest (= f). In this embodiment, the body portion 11 is half-shifted and pasted in the longitudinal direction 15.

FIG. 7 shows another one of the laying patterns, the alternate pasting P3. In this alternating pasting P3, the pavement block 2 is a combination of the parallel pasting P1 and the staggered pasting P2 alternately. In this embodiment, the parallel pasting P1 and the staggered pasting P2 are alternately installed one row at a time in the lateral direction 16 of the block main body 14, but the number of rows of the parallel pasting P1 and the number of rows of the staggered pasting P2 The combination of can be freely selected. Therefore, the alternate pasting P3 is a laying pattern with a high degree of freedom.

FIG. 8 shows the direction change pasting P4 which is one of the other laying patterns. The direction-changing pasting P4 is a series of pavement blocks 2 arranged in an orthogonal arrangement L along a flush end portion of the parallel pasting P1. The body portion 11 of the pavement block 2 of the orthogonal arrangement L is orthogonal to the body portion 11 of the pavement block 2 of the parallel attachment P1, and the tip of the shoulder portion 12 of the pavement block 2 of the orthogonal arrangement L is parallel attachment P1. It abuts on the outer surface of the shoulder portion 12 of the pavement block 2. The end portion of the pavement block 2 having the orthogonal arrangement L is aligned with the position of the tip portion of the shoulder portion 12 in the pavement block 2 of the parallel attachment P1. That is, the direction change pasting P4 is a combination of the parallel pasting P1 and the orthogonal arrangement L.

In this direction change pasting P4, parallel pasting P1 is used to secure the area, and a row of pavement blocks 2 arranged orthogonally as a partition line for partitioning the secured area and a border line for edging the peripheral edge of the area. It is a convenient laying pattern that can be used. Since the pavement block 2 used for the orthogonal arrangement L is a long straight line in which the body portions 11 are connected to each other with substantially no gap, a clear partition line or edging line without interruption can be formed.

FIG. 9 shows a grid pasting P5 which is still another one of the laying patterns. The lattice-pasted P5 is combined by changing the direction of the body portions 11 of the pavement block 2 so as to abut each other in a T-shape. The grid-pasted P5 is a laying pattern with the highest design.

In addition, the following additional laying patterns are possible.

For example, there is a basket wave pasted P6 shown in FIG. In this basket wave pasting P6, two paving blocks 2 are combined in a quadrangular shape with their ends flush with each other in the same manner as the parallel pasting P1, and the unit block is a unit block. It is a laying pattern laid so that the directions change alternately.

In addition, there is a composite tension P7 shown in FIG. The composite tension P7 is laid so that a plurality of parallel pasted P1 regions having different directions of the body portion 11 are formed. In this embodiment, the area of the parallel attachment P1 shown below is used as a parking space, the area of the parallel attachment P1 shown above is used as a runway to the parking space, and the body portion 11 indicates a vehicle indicated by a thick arrow in the drawing in each area. By arranging the vehicle so as to be substantially orthogonal to the traveling direction X of the vehicle, the load of the vehicle can be efficiently received. It is also possible to insert a row of paving blocks 2 having an orthogonal arrangement L shown in FIG. 8 between the regions of the parallel pasting P1.

All of these laying patterns can be constructed using only one type of pavement block 2. The parallel attachment P1 is satisfied by the above-mentioned condition 1 (having the body portion 11 and the four shoulder portions 12) and condition 2 (the lengths of the four shoulder portions 12 are equal). The staggered pasting P2 is established by the above-mentioned conditions 1, 2, and 4 (the inner dimension d of the side bay portion 13 is twice or more the width dimension c (width dimension) of the shoulder portion 12). Alternate pasting P3 is satisfied by the above-mentioned condition 1, condition 2 and condition 4. The direction change pasting P4, the basket wave pasting P6, and the composite tension P7 are based on the above-mentioned conditions 1, 2, and 3 (the ratio of the lengths of the dimension a in the longitudinal direction 15 to the shoulder width dimension b is approximately 2: 1). To establish. The grid pasting P5 is established by the above-mentioned conditions 1, 2, 2, 3 and 5 (the inner dimension d of the side bay portion 13 is equal to or greater than the shoulder width dimension b).

(2) Then, in various laying patterns formed by the combined arrangement of the pavement blocks 2, the greening rate can be changed by changing the area of the vacant space formed between the pavement blocks 2.

Here, in each laying pattern by the combined arrangement of the pavement blocks 2, the soil enters the side bay portion 13 of the pavement block 2 and is connected to the ground 1 by backfilling the soil. It is possible to plant turf (natural turf) in the soil around the body portion 11 by passing water sprinkling or the like and using the rainwater or the like.

Then, depending on the laying pattern, the area of the vacant space is different, and the area where the lawn can be planted per unit area is different, so that the greening rate can be different.

Described as a specific greening rate, the parallel pasting P1 having the highest greening rate uses about 22.2 pieces per square meter, so that the calculated greening rate is about 67%. Further, in the staggered P2 having the lowest greening rate, the number of used sheets per square meter is about 33.3, so that the calculated greening rate is about 50%. The greening rate of the other laying patterns is between 67% and 50%.

That is, in the alternating pasting P3 of FIG. 7, since the number of used per square meter is about 27.8, the calculated greening rate is about 59%. In the direction change pasting P4 of FIG. 8, since the number of used per square meter is about 22.2, the calculated greening rate is about 67%. Further, in the grid pasted P5, the number of used per square meter is about 32.3, so the calculated greening rate is about 51%. Therefore, the greening rate is as follows: parallel pasting P1 (about 67%) = direction change pasting P4 (about 67%) ≧ alternating pasting P3 (about 59%) ≧ grid pasting P5 (about 51%) ≧ staggered pasting P2 (about 50%) ) Etc. can be changed in at least 4 stages.

(3) The load capacity of the laying pattern can be changed depending on the arrangement of the pavement blocks 2.

Here, the pavement block 2 is laid on the ground 1 and the soil is backfilled, and the body portion 11 exposed on the ground is mainly subjected to a load (wheel load of the vehicle), so that the turf is planted. , You can get in the vehicle without damaging the grass.

Then, the number of body portions 11 that receive the load per unit area differs depending on the laying pattern, so that the load capacity can be different.

To describe the specific load capacity when a vehicle is driven in, the parallel paste P1 having the lowest load capacity can withstand up to 8 tons of vehicle in calculation. In addition, the staggered P2, which has the highest load capacity, can withstand up to 20 tons of vehicle in calculation. The load capacity of the other laying patterns is between 20 tons and 8 tons.

That is, the alternating pasting P3 in FIG. 7 can withstand up to 14 tons of vehicle in calculation. In the direction change pasting P4 of FIG. 8, a vehicle of up to 8 tons can be withstood in calculation. Further, the grid-attached P5 has a load capacity that can withstand up to a vehicle of 8 tons in calculation. Therefore, the load capacity is at least three stages, with up to 20 tons being staggered pasting P2, up to 14 tons being alternating pasting P3, and up to 8 tons being grid pasting P5, direction change pasting P4, and parallel pasting P1.

(4) As shown in FIG. 1, the pavement block 2 may be colored on the entire pavement block 2, but may be applied to at least the upper surface 11a of the body portion 11 (colored portion 41).

Here, the upper surface 11a or the like of the body portion 11 may be colored by painting or the like, or a pigment or the like may be mixed into the surface layer portion or the like of the body portion 11. Any color may be used for coloring, but when used for a partition line, a border line, or the like, it is preferable to use a color that is conspicuous and easy to understand, such as white or yellow. It can also be black, brown, orange, green, blue, or any other color.

At this time, if the pavement block 2 is manufactured by using a pressure vibration molding machine or the like, the pressure vibration molding machine can be pressed a plurality of times by automatic control, so that the colored portion 41 and the colored portion 41 are not used. A multi-layered pavement block 2 having a colored portion can be easily manufactured. Therefore, for example, it is possible to mold the base layer portion other than the surface layer of the pavement block 2 with an inexpensive raw material, and mold the upper surface 11a as the colored portion 41. It is preferable to use a pigment or the like for coloring the upper surface 11a of the body portion 11, but by using a paint having a heat-shielding property or a pigment having a heat-shielding property, the effect of lowering the ground surface temperature in summer can be obtained. Obtainable.

(5) As shown in FIG. 12, the shoulder portion 12 may have an adhesive portion 52 to which the artificial turf 51 can be adhered to the upper surface 12b.

Here, the upper surface 12b of the shoulder portion 12 is made lower than the upper surface 11a of the body portion 11 by the thickness of the artificial turf 51. Then, the shoulder portion 12 becomes an adhesive portion 52 of the artificial turf 51 by applying an adhesive 53 to the upper surface 12b (inclined surface) and adhering the artificial turf 51. The upper surface 12b of the shoulder portion 12 has a minimum area required for adhering the artificial turf 51. Further, as described above, since the upper surface 12b of the shoulder portion 12 has an inclined surface having a gentle inclination angle of 10 ° or less (for example, about 7 °), the adhesive portion 52 can easily attach the artificial turf 51. ing.

(6) The side bay portion 13 may have a shape and size that can accommodate a general-purpose interlocking block 61 (that is, a commercially available interlocking block) that is vertically divided in half. By doing so, in a situation where a larger adhesive area is required, such as when artificial turf is installed on the part where the vehicle is to be placed, FIGS. 5, 8, 10, 11, and 12 If there is a parallel pasting P1 such as the above, the adhesive area can be secured by inserting the general-purpose interlocking block 61 as it is into the combined side bay portion 13. Further, when only the side bay portion 13 is generated, the above-mentioned half-divided general-purpose interlocking block 61 can be inserted.

Specifically, the general-purpose interlocking block 61 can be of a general size. In this embodiment, for example, inside a vacant space (block accommodating portion) formed by combining two opposite side bay portions 13 of two pavement blocks 2 made into parallel pasting P1, about 20 cm in length and about 10 in width. One general-purpose interlocking block 61 having a size of about 6 cm and a height of about 6 cm can be inserted. However, the size of the general-purpose interlocking block 61 is not limited to the above.

At this time, it is preferable that the upper surface 12b of the shoulder portion 12 is set to substantially the same height as the upper surface of the general-purpose interlocking block 61. As a result, the upper surface of the general-purpose interlocking block 61 can be used as the adhesive portion 52 of the artificial turf 51 together with the adhesive portion 52 of the upper surface 12b of the shoulder portion 12.

<Action> The action of this example will be described below.

In the pavement block 2, a required amount of ground 1 is dug down, a sand layer or the like is laid on the bottom, the sand layer is smoothed, and a plurality of blocks are arranged on the smoothed sand layer in the required laying pattern, and then the body portion 11 is formed. The construction is carried out by backfilling the soil so that the upper surface 11a is exposed from the ground 1 and planting grass or the like on the portion of the body portion 11 excluding the upper surface 11a.

Then, by performing the pavement (green pavement) as described above, for example, both parking of the vehicle and greening become possible. By carrying out such green pavement, it is possible to contribute to mitigation of the heat island phenomenon in urban areas and the like.

Until now, such green pavement has the problem that the laying pattern is monotonous, the problem that the greening rate cannot be changed, the problem that the load capacity becomes low when trying to increase the greening rate, and the parking of vehicles. Depending on the situation, even if natural turf was planted, it did not take root well and turf withered easily. Therefore, it is required to solve these problems.

<Effect> According to this embodiment, the following effects can be obtained.

(Effect 1) The pavement block 2 has an I-shaped plan view having a body portion 11 and four shoulder portions 12. The shoulder portion 12 has an upper surface 12b lower than the upper surface 11a of the body portion 11, and has an extension dimension f equal to each other in a direction orthogonal to the longitudinal direction 15 of the body portion 11 in a state of being flush with the end portion of the body portion 11. I made it extend with. The pavement block 2 has a dimension a of the body portion 11 in the longitudinal direction 15 and a shoulder width dimension b obtained by adding the extension dimension f of the two shoulder portions 12 on both sides to the dimension e of the body portion 11 in the lateral direction 16 in the lateral direction. The ratio was 2: 1. The inner dimension d between the shoulders 12 provided at both ends of the body portion 11 in the longitudinal direction 15 was set to be at least twice the dimension c of the width of the shoulder portion 12 in the longitudinal direction of the body portion. The inner dimension d between the shoulder portions 12 is defined as the shoulder width dimension b or more.

As a result, at least five laying patterns of parallel pasting P1, staggered pasting P2, alternating pasting P3, direction change pasting P4, and grid pasting P5 can be carried out. Therefore, it is possible to obtain various laying patterns with only one type of pavement block 2 without particularly processing the pavement block 2. Further, since only one type of pavement block 2 is used by changing the arrangement, it does not become particularly difficult to walk in any laying pattern.

(Effect 2) The greening rate can be changed according to the laying pattern. This makes it possible to select the optimum laying pattern according to the required greening rate. Alternatively, the greening rate can be set according to the laying pattern. Moreover, the greening rate can be adjusted with only one type of pavement block 2.

(Effect 3) The load capacity can be changed according to the laying pattern. This makes it possible to select the optimum laying pattern according to the required load capacity. Alternatively, the load capacity can be set according to the laying pattern. Moreover, the load capacity can be adjusted with only one type of pavement block 2.

(Effect 4) At least the upper surface 11a of the body portion 11 of the pavement block 2 may be colored. As a result, it is possible to relatively freely create a display such as a lane marking line only by arranging the pavement blocks 2 in which the upper surface 11a of the body portion 11 is colored in a straight line.

The pavement block 2 in which the upper surface 11a of the body portion 11 is colored is preferably used in a state where the body portions 11 are continuously arranged to form a long straight line. For example, in the direction change pasting P4, by using the pavement block 2 in which the body portion 11 is colored in the portion of the orthogonal arrangement L other than the parallel pasting P1, the portion of the parallel pasting P1 is used as a parking section and the portion of the orthogonal arrangement L is used. Can be a lane marking. Since the pavement blocks 2 of this embodiment can be arranged so that the body portions 11 form a continuous long straight line, a clear division line is obtained, and the colored body portions 11 are discontinuous and interrupted, for example. It doesn't become difficult to see.

(Effect 5) An adhesive portion 52 may be provided on the upper surface 12b of the shoulder portion 12. By adhering the artificial turf 51 to the adhesive portion 52 of the shoulder portion 12 with an adhesive 53 or the like, the artificial turf 51 can be constructed (fixed), and the artificial turf 51 can be easily constructed. it can. This makes it possible to prevent the exposure of concrete and soil. Further, even in an environment where natural turf does not take root well and causes turf withering, green can be secured by constructing artificial turf 51 instead of natural turf. Further, since the artificial turf 51 can be adhered to the upper surface 12b of the shoulder portion 12, it is possible to prevent the artificial turf 51 from being displaced due to walking or the like. Therefore, both artificial turf 51 and natural turf can be flexibly supported.

(Effect 6) The pavement block 2 has a shape and size that can accommodate a general-purpose interlocking block 61 in which the side bay portion 13 is vertically divided in half. As a result, when two side bay portions 13 are arranged together, the general-purpose interlocking block 61 itself can be accommodated therein. By accommodating the general-purpose interlocking block 61 inside, it is possible to secure an adhesive area when a larger adhesive surface of artificial turf is required, such as a portion for a vehicle to enter. As a result, when the vehicle is parked, the artificial turf 51 can be made more difficult to shift due to the wheel load of the vehicle. On the other hand, when the upper surface 12b of the general-purpose interlocking block 61 is not used as an adhesive portion of the additional artificial turf 51, for example, a mortar is constructed inside the side bay portion 13 to form an adhesive portion of the additional artificial turf 51. It is necessary to create the 52, but if this is done, the cost, labor, and construction period required for the construction of the mortar (filling, curing, etc. of the mortar) will be required. Therefore, by using the upper surface 12b of the general-purpose interlocking block 61 as an adhesive portion of the additional artificial turf 51, it is possible to reduce labor and construction period as compared with the case of constructing mortar. The artificial turf is not limited to the adhesive, and may be bonded using, for example, a double-sided tape.
