Description

  The present invention relates to an anti-slip liner for a pedestrian crossing that is laid on a road surface and marked as a pedestrian crossing, and also serves as a non-slip for a pedestrian.

  In cold snowy areas, it is prone to slipping and falling accidents while walking on pedestrian crossings due to freezing of the road surface, and snow melting agents and anti-slip sand are sprayed. However, it must be managed day and night, and its cost and labor Is a problem.

The inventor has already proposed a paving block for preventing slipping as disclosed in Patent Document 1 (Japanese Patent No. 2676586).
This pavement block has a road surface forming part between a rubber pressure-fixing part containing a reinforcing material and a rubber road surface forming part not containing a reinforcing material with a nylon sheet different from rubber. When worn, the road surface forming part can be peeled off from the pressure fixing part together with the peeling sheet, and the concave and convex parts for connecting the paving blocks are fitted to each other and laid side by side on the road surface. It is like that.

However, this was replaced with all the road surface materials of roadways and sidewalks, so that the construction cost was expensive and the time required for the construction became longer, so that it was inevitable that the traffic obstacles were prolonged. In addition, although the concave and convex parts for connecting the paving blocks are fitted and laid together, unevenness occurs between the paving blocks, which not only interferes with the snowplow, but is also peeled off by the snowplow of the snowplow. There was a problem such as.
Japanese Patent No. 2676586

  Therefore, the present invention can be used as a sign for a pedestrian crossing just by laying it, as well as an anti-slip material on a pedestrian crossing, and easily constructed without full replacement with a road surface material. Another object of the present invention is to provide an anti-slip liner for pedestrian crossings that is capable of reducing the occurrence of unevenness and is less likely to cause unevenness and also has an effect of preventing damage to the snow removal blade of the snowplow.

  The anti-slip liner for a pedestrian crossing according to the present invention is formed by laminating a cushion layer made of a cushion material on a metal base plate and a rubber surface layer thereon, and forming an uneven surface for preventing slip on the upper surface of the surface layer. A first anti-slip liner in which a plurality of first liner plates of the first color among the colors are connected by a foldable connecting portion; a cushion layer made of a cushion material on a metal base plate; A rubber surface layer is laminated on the surface, and an uneven surface for preventing slippage is formed on the upper surface of the surface layer, and a plurality of second liner plates having the second color of the two colors can be bent. It consists of the 2nd anti-slip | liner liner connected by the connection part, These were laid alternately on the road surface, and it was made to be able to be marked as a crosswalk.

  In each of the first and second anti-slip liners, it is preferable that the connecting portion between the liner plates is a groove, and the connecting portions are foldably connected by a connecting base cloth embedded in each cushion layer.

  Further, it is preferable that at least one edge portion of the base plate is bent upward along the edge of the cushion layer and the surface layer at a portion other than the connecting portion between the liner plates.

The anti-slip liner for pedestrian crossings of the present invention has the following effects.
(1) Consists of two-color anti-slip liners, each of which is composed of a plurality of liner plates connected by a foldable connecting part, which can be easily traversed in a short time by laying them alternately on the road surface. The sidewalk can be marked, and the construction period and construction cost of pedestrian crossing can be reduced. Further, in addition to being able to clearly mark the two colors, the coating film is not worn out unlike the marking by paint, so that the clear marking can be maintained for a long time and the maintenance cost can be reduced.

(2) Each liner plate has a three-layer structure in which a cushion layer made of a cushioning material is laminated on a metal base plate and a rubber surface layer is laminated thereon, and an uneven surface for preventing slippage is formed on the upper surface of the surface layer. So, while ensuring the toughness and adhesion to the roadbed by the metal base plate, the rubber surface layer with the uneven surface has an anti-slip effect, and the rubber's inherent elasticity can prevent the adhesion of snow and ice. The cushion effect of the cushion layer, which is the middle layer, can promote the separation of snow and ice from the surface layer in addition to ensuring the safety of pedestrians.

(3) Since each of the two-color anti-slip liners is formed by connecting the liner plates as described above with a connecting portion that can be bent, unevenness does not occur even when the vehicle passes repeatedly.

  As in the invention according to claim 2, if the connecting portion between the liner plates is a groove and is connected to each other by a connecting base fabric embedded in each cushion layer, the heat of the asphalt roadbed Good followability to deformation and stress deflection. In addition, there is an anti-slip effect due to the groove, and also a drainage effect.

  As in the invention according to claim 3, when the edge portion of the base plate is not connected to the liner plate and is bent upward along the edge of the cushion layer and the surface layer, It is possible to prevent the snow removal blade or the like from biting into the rubber surface layer at the bent edge portion of the base plate.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  This anti-slip liner for pedestrian crossings uses a combination of a first anti-slip liner and a second anti-slip liner of different colors. As shown in FIGS. When marking with two colors of black and white, the first anti-slip liner 1 having a white surface and the second anti-slip liner 2 having a black surface are alternately arranged in the walking direction of the pedestrian as a pedestrian crossing 4. And lay it on the roadbed.

  In this case, as shown in FIG. 3, the surface layer of the asphalt roadbed 5 of the roadway 3 is cut into a groove shape only in the region that becomes the pedestrian crossing 4, and the anti-slip liners 1 and 2 are alternately arranged in the groove 6 to form the bottom surface of the groove. Adhere directly to the groove 6 to fill the groove 6. 4A shows a state in which the groove 6 is viewed from the side of the sidewalk 7, and FIG. 4B shows a state in which the groove 6 is compensated by the anti-slip liners 1 and 2. FIG.

  As shown in FIG. 5, the first and second anti-slip liners 1 and 2 have substantially the same structure except for the color of the surface layer, and as shown in FIG. 9 is continuous (integral), and can be bent at the connecting portion 9 as shown in FIG. Each liner plate 8 has a three-layer structure in which a cushion layer 11 made of a cushion material is laminated on a base plate 10 that is a steel plate, and a rubber surface layer 12 is laminated thereon. In the liner plates 8, the base plate 10 and the base plate 10 are separated from each other, but the cushion layers 11 are connected by a connecting base fabric 14 made of canvas embedded in the cushion layer 11 itself. Each rubber surface layer 12 is integrally continuous by forming a connecting groove 15 that can be bent in one belt-like rubber plate.

  The rubber of the material of the surface layer 12 is preferably a hard rubber having high weather resistance and high wear resistance, but the material (cushion material) of the cushion layer 11 may be a flexible rubber. As shown in FIGS. 8 and 9, the upper surface of the surface layer 12 is an uneven surface for preventing slippage like a tread of an automobile tire.

  In the case of this example, at least one of the black and white anti-slip liners 1 and 2, the black second anti-slip liner 2 is not connected to the liner plate 8 between the liner plates 8 as shown in FIG. One end edge 10 a of the base plate 10 of each liner plate 8 is bent upward along the edges of the cushion layer 11 and the surface layer 12, and the bent end extends to the upper surface of the surface layer 12. The corner portions at both ends of the edge portion 10a bent upward in this way are diagonally chamfered as shown in FIG.

  As shown in FIG. 7, the black and white anti-slip liners 1 and 2 are directly bonded to the bottom surface of the base plate 10, which is a steel plate, on the bottom surface of the groove 6 from which the asphalt roadbed 5 is cut with an adhesive (for example, a solventless adhesive). As shown in FIG. 2, the edge portions 10 a of the base plate 10 bent upward are viewed from the walking direction of the pedestrian crossing 4, because they are alternately arranged so as to cross the roadway 3. Every other arrangement except for the white anti-slip liner 1 without it, the end edges 10a of the black anti-slip liners 2 extend in parallel in the vehicle traveling direction.

  Looking at the entire crosswalk 4 by the black and white anti-slip liners 1 and 2, the white anti-slip liner 1 and the black anti-slip liner 2 are alternately marked with a white belt, and each anti-slip liner 1 and 2 has a liner. The plate 8 is a grid-like arrangement like a paving block laid in the traveling direction of the vehicle and the walking direction of the pedestrian crossing 4, and each upper surface is an uneven surface for preventing slipping like a tread of an automobile tire. However, in each of the anti-slip liners 1 and 2, the liner plates 8 constituting the anti-slip liners 1 and 2 are continuously connected in the traveling direction of the vehicle by a foldable connecting portion 9 having a connecting groove 15, and the pedestrian crossing 4 is walked. In the direction, the bent edge portions 10a of the base plate 10, which is a steel plate, are arranged in parallel every other direction.

  Accordingly, the liner plates 8 are arranged in a grid pattern like paving blocks, the material of the surface layer 12 of each liner plate 8 is rubber, and the upper surface thereof is an uneven surface such as a tread of an automobile tire. The anti-slipping effect is high due to the synergistic effect that the intermediate layer of each liner plate 8 is the cushion layer 11, and the effect of preventing the adhesion of snow and ice is also high.

  When viewed from the vehicle traveling on the roadway 3, as shown in FIG. 11, the liner plates 8 of the anti-slip liners 1 and 2 are sequentially bent by the cushion layer 11 of the middle layer as the tire 16 rolls to perform a buffering action. The liner plates 8 constituting the anti-slip liners 1 and 2 are continuously connected in the traveling direction of the vehicle by the bendable connecting portion 9 having the connecting groove 15, so that even if the vehicle is repeatedly passed over a long period, Land does not occur. Moreover, the followability with respect to the heat deformation, stress deflection, etc. of the asphalt roadbed 5 is good.

  Further, for the snow removal blade of the snowplow, the bent edge portion 10a of the base plate 10 which is a steel plate is arranged in every other parallel direction extending in the traveling direction of the vehicle. The snow removal blade can be prevented from biting in while ensuring sufficient cushioning.

  For example, the length L of the anti-slip liners 1 and 2 is arbitrarily determined according to the width of the sidewalk of the pedestrian crossing 4, that is, the length of the white belt or the black belt. Since the marking widths of the white band and the black band are defined within a range of 300 to 500 mm, the width is within this range. This width W is also the length of each liner plate 8 in the walking direction. On the other hand, the length of each liner plate 8 in the vehicle traveling direction is 300 to 400 mm.

  Regarding the thickness, the thickness of the base plate 10 is 4.5 to 6 mm, the thickness of the cushion layer 11 is 3 to 6 mm, the thickness of the surface layer 12 is 8.5 mm or less, and the height of the uneven surface is about 5. 5 mm. The height of the edge part 10a bent to the upper side of the base plate 10 shall be 15-20 mm.

  In the above embodiment, the anti-slip liners 1 and 2 of two colors of black and white are used, but the color is not limited to black and white. Moreover, although the edge part 10a bent on the upper side of the baseplate 10 was provided in the black anti-slip liner 2, it may be provided in the white anti-slip liner 1 and may be provided in both.
