Description

  The present invention relates to a sidewalk.

  Many trails such as mountain trails and nature parks are bare footpaths from which only vegetation has been removed, and people walk on debris that has been solidified by treading. On slopes, etc., log staircases with logs are used to suppress sediment runoff from the edge of the sidewalk. However, the log staircase has a short service life because it tends to collapse due to rainwater, snowmelt water, frost pillars, etc., and pedestrians' pressure and winter snow pressure, etc. Can cause discontinuous vegetation and can cause natural destruction due to the expansion of bare land.

  For example, in Patent Document 1, in order to suppress scouring of the soil on the side of the log stairs due to surface water during rainfall, a concave portion is provided in the center of the log arranged in the log stairs, and surface water is provided in the center of the log. The technology which summarizes is described.

Japanese Patent Laid-Open No. 11-71709

  However, even the technique described in Patent Document 1 does not solve the problem that the service life is short due to the collapse of logs due to the pressure of pedestrians and the pressure of snow, and the point that vegetation needs to be removed. There is no change in the vegetation on the sidewalk that is difficult to recover.

  In view of the above problems, the present invention provides a sidewalk that can have a longer service life and can reduce the removal of vegetation and the change of the surface shape for sidewalk installation. For that purpose.

  The present invention is a sidewalk having a plurality of mesh-like treads and a plurality of connecting members disposed between the mesh-like treads, wherein the connecting members form the mesh-like treads on an inclined surface or an uneven surface. It is related with the sidewalk characterized by hold | maintaining in the different position according to.

  According to the present invention, it is possible to provide a sidewalk that can have a longer service life, can reduce the removal of vegetation and change the surface shape for sidewalk installation, and can be bare.

[First Embodiment]
As shown in FIG. 1 which is a schematic perspective view, FIG. 2 which is a schematic cross-sectional view, and FIG. 3 which is a schematic plan view, the sidewalk 100 according to the first embodiment of the present invention includes a plurality of sidewalks 100. The mesh-like tread 110, a plurality of connecting members 120 disposed between the mesh-like tread 110, the binding belt 130 fixed to the mesh-like tread 110 and the connecting member 120, and the mesh tread 110 are positioned. A screw pile 140 and a wire 150. The sidewalk 100 is a sidewalk provided on an inclined ground having an inclination in a direction indicated by an arrow in FIG.

  Reticulated tread board 110 is a walking area where a person walks. The mesh footboard 110 includes a walking surface 112 and a frame 114 that is disposed so as to be substantially orthogonal to the peripheral edge of the walking surface 112. The walking surface 112 is a mesh-like member having strength enough to withstand human walking, and is made of, for example, expanded metal or grating. Note that the grating may be a combination of steel and wood in a lattice shape or a continuous shape. The frame 114 only needs to be fixable to the walking surface, and is made of, for example, a metal fixed to the walking surface by welding or the like. The frame 114 may have a through-hole through which a bolt or a staple for connecting the mesh tread 110 to the connecting member 120, a through-hole for connecting a wire 150 for positioning on the ground, and the like. Good.

  The mesh-like step board 110 is installed on the upper side away from the ground by the connecting member 120. Thereby, since a pedestrian can walk without stepping on the ground, the outflow of earth and sand due to a person's treading pressure during rain or the like can be suppressed. Moreover, since the walking surface 112 of the mesh-like tread 110 is mesh-like, it can transmit sunlight and rainwater. Thereby, the mesh-like tread board 110 is hard to prevent the growth of the plant in the downward direction.

  Note that the length of the mesh tread 110 can be changed according to the inclination. For example, if the length of the mesh tread 110 is made shorter on a steep slope, the height of the step provided by the connecting member 120 can be reduced to facilitate walking of the pedestrian. In addition, if the length of the mesh-like step board 110 is made longer on a gentle slope, the number of connecting members 120 can be reduced and the sidewalk 100 can be installed at a lower price.

  The connecting member 120 connects the plurality of mesh-like treads 110. The connecting member 120 is formed by stacking a plurality of logs in a step shape, and each step is a step portion for providing a step between the pedestal portion 122 in contact with the ground (inclined surface) and the adjacent mesh-like tread 110. 123 and a holding portion 124 for holding a mesh-like tread. The pedestal part 122, the step part 123, and the holding part 124 can all be produced by combining thinned materials.

  The pedestal part 122 is a base made of a plurality of logs. The number and length of the logs constituting the pedestal part 122 can be arbitrarily set. For example, when it is desired to increase the strength of the sidewalk 100, the number of logs constituting the pedestal portion 122 may be increased or the logs may be lengthened. The pedestal part 122 divides and arranges a plurality of logs shorter than the width of the sidewalk 100 in the width direction of the sidewalk 100 to facilitate replacement at the time of deterioration due to treading pressure or soil moisture, and as described later in the width direction. Application to slopes can be facilitated. The pedestal part 122 may be arranged with a log in a direction perpendicular to the holding part 124 of the slope, and the longitudinal direction of the log may be arranged in a direction along the slope.

  The step portion 123 is used when a step is provided between the adjacent mesh-like treads 110. For example, when the diameter of the steep slope or log is small, the stepped portion 123 may be formed by stacking logs to form a plurality of steps, or when the diameter of the gently inclined land or log is large, the stepped portion 123 may be one step or the stepped portion 123 may be installed. May be omitted.

  The holding part 124 is disposed in front of and behind the mesh-like tread 110, and the frame 114 (mesh-like tread 110) is formed by bolts that penetrate the frame 114 and the holding part 124, nuts that fix the bolts, and staples that penetrate the frame 114. Connected to.

  The connecting member 120 (holding part 124) holds the mesh-like tread 110 at different positions according to the inclination or unevenness of the ground. Specifically, as shown in FIG. 2, the mesh footboard 110 located below the slope is connected to the holding portion 124 on the side closer to the base, and the mesh footboard 110 located above the slope is more It is connected to the holding part 124 on the side far from the base. As a result, the connecting member 120 can easily adjust the position of the mesh tread 110 in the height direction, and the sidewalk 100 can be installed substantially horizontally even on an inclined ground.

  The binding belt 130 binds and fixes the frame 114 of the front and rear mesh treads 110 to the stepped portion 123 and the holding portion 124 of the connecting member 120. The binding belt 130 can be a belt made of a known material such as a metal such as iron, leather, and synthetic resin.

  The screw pile 140 includes a screw part 142 inserted into the ground and a C-shaped or ring-shaped anchor part 144 for mooring the wire 150. The screw portion 142 can be rotated and inserted into the ground by human power, and can also be inserted obliquely while avoiding stones in the ground. Therefore, unlike the well-known log pile as described in Patent Document 1, the screw part 142 can suppress the destruction of the soil structure at the time of insertion, and hardly causes the outflow of soil. The anchor portion 144 connects the ends of the wires 150 or hangs the ends of the hook-shaped wires 150 to connect and fix the wires 150 to the screw portions 142. At this time, the C-shaped or ring-shaped anchor portion 144 makes it possible to extend the wire 150 in the direction of the mesh tread 110, regardless of the direction in which the screw portion is inserted.

  One end of the wire 150 is fixed to the edge (for example, the frame 114) of the mesh-shaped tread 110, and the other end is fixed to the anchor portion 144 to position the mesh-shaped tread 110. The wire 150 can be an arbitrary member such as a metal cable.

  As described above, the sidewalk 100 of the present embodiment allows a pedestrian to pass without stepping on the ground, and therefore can suppress vegetation destruction due to treading pressure, soil disturbance during rainfall, and the like. Further, in the sidewalk 100 of this embodiment, since sunlight and rainwater permeate the mesh-like step board 110, plants can grow on the lower part of the sidewalk 100, and vegetation destruction on the ground surface due to the installation of the sidewalk 100 can be suppressed. Further, since the sidewalk 100 of the present embodiment allows sunlight and rainwater to pass through the mesh-like step board 110, plants can grow on the lower side of the sidewalk 100 even when provided on a bare ground surface by installing a conventional sidewalk. Yes, it is possible to promote vegetation restoration and natural restoration.

  Further, the sidewalk 100 of this embodiment is a walking area where a person walks with the mesh-like tread 110 that is installed above and separated from the ground by the connecting member 120, and is in contact with the ground only by the pedestal portion of the connecting member. It is possible to reduce the change in the surface shape during installation.

  Moreover, since the sidewalk 100 of this embodiment uses a thinning material for the connection member 120, it is inexpensive and has less burden on nature.

[Second Embodiment]
FIG. 4 is a schematic perspective view showing a sidewalk 200 according to the second embodiment of the present invention. The sidewalk 200 according to the present embodiment is a sidewalk provided on an inclined ground having an inclination in the direction indicated by two arrows in FIG. Since the sidewalk 200 according to the present embodiment has substantially the same configuration as the sidewalk 200 in the first embodiment except that the configuration of the connecting member 220 is different, the description of the common parts is omitted.

  In the sidewalk 200, the height from the ground in the width direction of the mesh-like step board 110 differs between the mountain side and the valley side.

  Specifically, the connecting member 220 has a log constituting the pedestal portion 122 only on the valley side (lower left side in the drawing). By changing the number of hills and valleys of the logs constituting the pedestal part 122 according to the ground surface inclination, the connecting member 220 allows the mesh-like tread 110 to be positioned at a lower position from the ground on the mountain side (upper right side in the drawing). The mesh-like tread 110 is held horizontally by holding it at a higher position from the ground on the valley side. In addition, the method of adjusting the height of the mesh-like step board 110 is not limited to the presence or absence of the log which comprises the base part 122, For example, the connection member 220 changes the step number of the log which comprises the holding part 124, for example. The height of the mesh-like step board 110 on the mountain side and the valley side may be changed.

  At this time, the screw pile 140 and the wire may position the mesh tread 110 from the mountain side as shown in FIG. 4, and the pedestrian progresses (as shown in FIG. 2) as in the first embodiment. The mesh tread 110 may be positioned from the direction.

  According to the present embodiment, it is possible to install a sidewalk on land having an inclination in the width direction of the sidewalk, and it is possible to install the sidewalk on more various slopes.

[Third Embodiment]
FIG. 5 is a schematic cross-sectional view showing a sidewalk 300 according to the third embodiment of the present invention. The sidewalk 300 according to the present embodiment is a sidewalk provided on a slope with a larger amount of snow. Since the sidewalk 300 according to the present embodiment has the same configuration as the sidewalk 100 in the first embodiment or the sidewalk 200 in the second embodiment except that the configuration of the wires is different, description of common parts is omitted.

  The wire 250 is a stretchable wire including a spring member 252. The spring member 252 extends due to the snow glide (snow in the snow layer) during snow accumulation, and the wire 250 moves the sidewalk 300 downward along the slope together with the glide snow. Thereby, the wire 250 can suppress the destruction of the sidewalk 300 by the glide at the time of snow accumulation. The sidewalk 300 according to this embodiment has a large amount of snow. For example, the effect is remarkable in an area where the amount of snow is about 3 m to 10 m.

  The amount of snow glide increases depending on the snow depth and slope slope, and increases when either of them increases. The spring member 252 only needs to have an amount of expansion and contraction that is equal to or greater than the amount of snow in the snow layer.

  Further, in the present embodiment, as shown in FIG. 5, when the pedestal part 122 is arranged in a direction in which the longitudinal direction of the log is along the slope, when the snow glide is generated and the wire 250 is extended, the pedestal part 122 is Only the step part 123 and the holding part 124 can slide on the frozen part on the pedestal part 122 without moving. Therefore, such a pedestal portion 122 can make it difficult for the stepped portion 123 and the holding portion 124 to fall from the pedestal portion 122 when a snow glide occurs and the wire 250 extends. At this time, it is desirable that the pedestal part 122 is longer than the amount of snow in the snow layer.

  According to this embodiment, even when a sidewalk is installed on a land with a large amount of snow, it is possible to lengthen the sidewalk life.
