Description

  The present invention relates to a greening pavement in which a panel main body is laid on a leveled ground, the panel main body is filled with vegetation soil, and a ground cover plant is planted in the vegetation soil.

  Various greening measures have been taken as countermeasures such as the suppression of the heat island phenomenon associated with urbanization and the suppression of global warming associated with an increase in carbon dioxide. As part of such efforts, in urban areas, attempts are being made to green the rooftops and walls of buildings, and greening sites such as parking lots. With regard to greening of buildings, for example, a method of covering wall surfaces and the like by taking ivy and other climbing plants is taken, and it is a place where you can often see and hear the reports that praise the effect. However, it seems that there are not many reports of large-scale greening of large sites such as parking lots.

  Looking at the prior art, there is one in which the pavement itself is a green pavement, and an example is JP-A-2009-185456. This invention is a grid-like load distribution having continuous gaps formed by connecting roadbed materials in a grid and three-dimensionally with an adhesive solution within the thickness of the roadbed made of roadbed materials laid on the construction site. It has a structure called greening pavement in which a structure is formed and a vegetation base material is held in a gap included in the roadbed. And since the grid-like load distribution structure is formed within the thickness of the roadbed, it is said that there is an effect that it can withstand the load of the vehicle etc., but in this case, due to the difference in the pavement technology of the roadbed The results will be affected, and it can only be carried out in a place that can withstand pavement work.

A space 12 is provided between the protrusions, and the space 12 is entirely connected in a plane, and is filled with vegetation soil 13 (see FIG. 13). Note that the planar shape of the panel body is not limited to a square, and a rectangular, triangular, or other connectable polygonal shape or a combination thereof can be selected.

  Each protrusion 11 has a shape that can be said to be a substantially quadrangular pyramid that is tapered from the base portion 14 toward the top portion 15 (see FIG. 3). (See FIG. 4). Each of the protrusions 11 has an opening 16 passing through the inside and outside of each of the four surfaces, and a radially outward reinforcing rib 17 is formed at the outer corner. Further, upper and lower sleeve ribs 18 and 18 are formed substantially in parallel on the left and right sides of the opening 16, and the sleeve ribs 18 and 18 are closed at the outer ends, or will be described later. The portion provided with the connecting means 20 is closed at a slightly inner position, and the sleeve-like ribs 18 and 18 of the adjacent protrusions 11 are joined at the outer end.

  The opening 16 may be closed as shown in FIG. 4 or may reach the lower end of the protrusion 11. By making the opening part open to the lower end, the root of the plant can be entangled with the base part, and the degree of integration with the panel body can be increased, and the opening part 16 is open to the lower end, so that water can be easily removed from the panel body. There is also an advantage of doing. In addition, by providing the reinforcing rib 17 and the sleeve-like ribs 18 and 18 on the protrusion 11, the desired strength can be obtained even if the rib height is lowered.

  The panel body also has a small opening 19 at the top 15, which is surrounded by the upper end of the reinforcing rib 17. The small opening 19 is also used for attaching auxiliary tools 32 and 34, which will be described later, but also has a function of improving air permeability and water permeability like the side opening 16. Further, the four corners of the base portion 14 are slightly chamfered so that a rhombus cavity 14a is formed, and the panel body is connected to the combined base portion 14 constituting the same. And can be cut. By cutting the panel body, it is possible to easily lay the greening pavement material 10 according to the shape of the site and other factors.

  In the embodiment of the present invention, the panel main body constitutes a square panel main body in which a plurality of protrusions 11 and a space 12 provided between the protrusions are coupled in the front-rear and left-right directions. The shape panel main body has connecting means 20 for connecting the main bodies at the side portions and laying them in the front, rear, left and right. The connecting means 20 includes a convex portion 21 provided on one rectangular panel main body and a mating convex portion 22 provided on the other adjacent rectangular panel main body so as to overlap an upper portion or a lower portion of the convex portion 21.

And the connecting mating portion 26 of the connecting claw piece 25, the projection 27 provided on one side of the rectangular panel main body to be connected, and the recess 28 that engages with the projection 27. It is only necessary to have one of these elements.

  In the case of the illustration, an example in which all three elements are provided as the connecting means 20 is shown, and the convex portion 21 as the first element is provided so as to overlap the counterpart convex portion 22 (FIGS. 5 to 5). 8 and FIG. 11). The projection 21 and the mating projection 22 are provided with through holes 23 and 24 in the vertical direction. When the panel body is laid in the front and rear, left and right, the through holes 23 and 24 are secured with pegs or the like. It can be used as a means for fitting a nail and connecting adjacent panel bodies. Furthermore, in order to fix the panel body to the ground, it can also be used as a hole into which an anchoring member is driven.

  Further, the connecting claw piece 25 which is the second element of the connecting means 20 has a pair of upwardly tapered vertical pieces 25a and 25a provided on the mating convex portion 22 side, and a connecting piece 25b connecting them. (See FIG. 3). The connecting claw piece 25 is provided on the mating convex portion 22 located at the lowest position, and has a structure projecting upward on the outside thereof. The gap 25 ′ extends from the convex portion 21 to the coupling mating portion 26. The part is configured to enter and engage (see FIG. 8). The connecting mating part 26 is constituted by sleeve-shaped ribs 18 and 18 formed on the left and right sides of the opening 16 and a part surrounded by an outer part closing the rib (FIGS. 3 and 5). Etc.). In addition, a pair of protrusions 27 as third elements are provided on the left and right sides of the convex portion 21, and a pair of recesses 28 are provided on the left and right of the connecting claw piece 25 at a position where it engages with the convex portion 27 (see FIG. 12). ).

  In the illustrated embodiment, the connecting means 20 configured as described above has coupling claws on two adjacent sides of the four sides of the panel body having a rectangular planar shape, as is apparent from FIG. 25 and a recess 28 are provided, and another adjacent two pieces are provided with a convex portion 21, a connection partner portion 26, and protrusions 27 and 27, respectively. In other words, a connecting counterpart 26 is provided on the other side parallel to the side on which the connecting claw piece 25 is provided (see FIGS. 9 and 10). As described above, the panel main body in the illustrated example can be laid on the front, rear, left and right by the connection means and configuration of the three elements. However, for example, a modification is possible in which the first element and the second element are arranged separately without being provided at the same position, and the third element is omitted.

  The greening pavement material 10 of the present invention having such a configuration is used by being laid on a ground that has been laid down by spreading sand G2 on the roadbed G1 (see FIG. 13). In that case, the greening pavement 10 is constructed such that the panel bodies are connected to each other by the connecting means 20 and fixed to the ground as needed, and is laid on the front, back, left and right. Make it almost coincide with the surface of the ground before leveling. A vegetation soil 13 is filled in the void 12 of the panel body laid as described above, and a ground cover plant 29 is planted in the vegetation soil 13. The above-mentioned shiba was used for the ground cover plant 29. Thus, the greening pavement material 10 of the present invention can be used for greening a site in a desired range.

  In the greening pavement 10 of the present invention, an auxiliary tool for providing a line, a section, a positioning part or a boundary on the upper surface of the panel body is also used in combination with one or more protrusions of the panel body. It is possible to install a straight line indicating a parking area, a car stop, etc., and to provide multi-functionality as a device. FIG. 14 shows, as an example, a greening parking lot 30 constructed using the greening pavement material 10 of the present invention. The greening parking lot 30 itself connects the greening pavement material 10 according to the present invention to the connecting means 20 described above.
