Description

  The present invention relates to a paving mat used when paving mainly using gravel or wood chips.

  In the promenade and approach, various types of pavement are applied, such as gravel bed, washout finish, concrete, resin, stone sticking, interlocking, brick, etc. For example, in the case of the approach that leads to the entrance, to create a luxury feeling One option is to use stone as the pavement.

  On the other hand, symbiosis with nature has recently been emphasized, and instead of concrete or resin with a hard image as a texture, materials rich in nature such as wood chips, sleepers or boards made from crushed thinned wood However, it is used everywhere along with conventional gravel and lawn.

  However, when a wheelchair is used to travel on a paved road where wood chips and gravel are used, the wheel of the wheelchair bites into the wood chips and gravel due to its weight, which makes it difficult to travel.

  In particular, in the case of gardens such as nursing homes and recreational facilities, the above-mentioned problem becomes more serious because the frequency of use of wheelchairs is high.

  The present invention has been made in consideration of the above-described circumstances, and an object thereof is to provide a paving mat capable of improving the traveling performance of a wheelchair.

  In order to achieve the above object, the paving mat according to the present invention has a filling hole filled with gravel, wood chips and other granular paving materials from one surface to the other surface as described in claim 1. The elastic sheet material is formed by penetrating and is provided with a slip stopper on one surface of the elastic sheet material.

  In the mat for paving according to the present invention, the elastic sheet material is constituted by a honeycomb-like continuous partition, and a hexagonal space surrounded by the continuous partition is used as the filling hole.

  The pavement mat according to the present invention is made of an elastic sheet material in which a filling hole filled with gravel, wood chips or other granular pavement material is formed penetrating from one surface to the other surface. The elastic sheet material is laid on the roadbed so that the other surface of the elastic sheet material comes into contact with the roadbed, and the filling holes formed in the elastic sheet material are filled with gravel, wood chips and other granular pavement materials.

  In this way, when the wheelchair is run, there is no concern that the wheels will bite into the granular pavement material such as gravel and wood chips, and the anti-slip is provided on one surface of the elastic sheet material. Thus, it is possible to improve the mobility of the wheelchair while taking advantage of natural materials such as gravel and wood chips.

  As the elastic sheet material, for example, a sheet material formed of rubber or plastic can be selected.

 As long as the elastic sheet material is formed with a filling hole so as to come out from one surface to the other surface, in other words, from the front surface to the back surface, and the filling hole is filled with granular pavement material, the configuration thereof is arbitrary, For example, the elastic sheet material can be constituted by a honeycomb-like continuous partition, and a hexagonal space surrounded by the continuous partition can be used as a filling hole.

  Hereinafter, embodiments of a paving mat according to the present invention will be described with reference to the accompanying drawings. Note that components that are substantially the same as those of the prior art are assigned the same reference numerals, and descriptions thereof are omitted.

  1 and 2 are views showing a paving mat according to the present embodiment. As can be seen from these drawings, the pavement mat 1 according to the present embodiment is composed of a rubber mat 2 as an elastic sheet material, and an anti-slip 3 is provided on one surface of the rubber mat.

  The rubber mat 2 includes a honeycomb-like continuous partition wall 4, and a hexagonal space surrounded by the continuous partition wall is used as a filling hole 5.

  Here, the filling hole 5 is formed so as to penetrate from one surface of the rubber mat 2 to the other surface, and is filled with gravel 6 as a granular paving material.

  The paving mat 1 preferably has an overall size of, for example, 90 cm × 90 cm and a thickness of 15 to 20 mm. The continuous partition wall 4 is preferably configured such that the wall thickness is, for example, 25 to 30 mm, and the maximum inner dimension of the filling hole 5 that is a hexagonal space is 100 mm.

  In such a case, the maximum gravel dimension can be set to 10 to 15 mm, for example.

  A pin hole 7 is appropriately formed in the continuous partition wall 4, and the pin 8 is inserted into the pin hole and driven into a roadbed (not shown), thereby preventing the pavement mat 1 from being displaced. . Considering the degree of fixing to the roadbed, the pin 8 is preferably about 100 to 150 mm in length, for example.

  In order to perform paving using the paving mat 1, first, the roadbed is leveled if necessary, and then the roadbed material 32 is placed on the roadbed 31 as shown in FIG. Next, the roadbed material is compacted with vibration rollers to form the roadbed 33. As the roadbed material 32, for example, crushed stone may be used.

  Next, the paving mat 1 is laid on the roadbed so that the other surface of the rubber mat 2 is in contact with the roadbed 33.

  Next, as shown in FIG. 3 (b), gravel 6 is filled into the filling holes 5 formed in the rubber mat 2.

  Finally, the pin 8 is inserted into the pin hole 7 and driven into the roadbed 33.

  In this way, when a wheelchair or bicycle travels on the pavement mat 1, when the wheel is positioned on the gravel 6, the load of the wheelchair or bicycle is transmitted to the roadbed 33 via the gravel 6. Since the periphery of 6 is restrained by the inner wall surface of the continuous partition wall 4, there is no fear of spreading to the periphery due to the load of a wheelchair or a bicycle.

  Therefore, there is no concern that wheelchairs or bicycle wheels will bite into the gravel 6.

  On the other hand, when the wheel is positioned on the continuous partition wall 4, the slipping of the wheel is prevented by the action of the anti-slip 3.

  As described above, according to the pavement mat 1 according to the present embodiment, the rubber mat 2 is constituted by the honeycomb-like continuous partition walls 4, and gravel is formed in the filling holes 5 that are hexagonal spaces surrounded by the continuous partition walls. 6 is filled, so when a wheelchair or a bicycle is run, there is no concern that the wheels will bite into the gravel, and the anti-slip 3 is provided on one surface of the rubber mat 2, so that the wheels do not slip. Thus, it is possible to improve the traveling performance of wheelchairs and bicycles while taking advantage of gravel as a natural material.

  In the present embodiment, the paving mat is composed of the rubber mat 2, but the paving mat according to the present invention is only required to be an elastic sheet material, and is not limited to rubber as a material. A paving mat may be configured.

  In the present embodiment, the rubber mat 2 is constituted by the honeycomb-like continuous partition walls 4 and the hexagonal space surrounded by the continuous partition walls is used as the filling holes. However, the filling holes according to the present invention include gravel, wood chips, and the like. As long as the granular pavement material is filled, any configuration may be used, and a polygonal space, for example, a square filling hole may be used instead of the hexagonal space. In this configuration, the continuous partition walls are lattice-shaped continuous partition walls. Furthermore, the filling hole according to the present invention does not necessarily have a form surrounded by continuous partition walls, and the configuration thereof is arbitrary, such as a form formed by penetrating a plurality of circular holes in an elastic sheet material.

  Moreover, although gravel was employ | adopted as a granular pavement material in this embodiment, it may replace with this and may employ | adopt the wood chip formed by crushing a thinning material. Even in such a configuration, it is possible to improve the traveling performance of the wheelchair while placing importance on coexistence with nature.
