Description

  The present invention relates to a side groove block, and more particularly to a side groove block installed at a boundary between a roadway and a sidewalk.

  Many of the side groove blocks installed at the boundary between the roadway and the sidewalk are provided with a concave groove in the upper part thereof (for example, see Patent Document 1). In addition, there is a structure in which a large number of lattice-like or mesh-like concave grooves are formed in the upper part (see, for example, Patent Document 2). Furthermore, there is a surface having a tile-like protruding plate surface or the like (see, for example, Patent Document 3). There is also a metal protective frame with a slip stopper attached to the upper end of the U-shaped groove side wall (see, for example, Patent Document 4). These have the effect of improving drainage and preventing slipping of cars and pedestrians.

  The grooves and irregularities provided on the upper surface of the conventional concrete side wall as described above are provided for the purpose of improving drainage or preventing slipping when people or cars pass. is there. In other words, it is not sufficient as a warning when the vehicle approaches the sidewalk side abnormally from the roadway side due to the driver's dozing or looking aside.

  In addition, if the structure is changed so that the height of the curb is increased so that the vehicle does not ride on the sidewalk side, the construction cost will increase, and there may be a risk that a small child will be hidden behind the curb and a dangerous situation will occur. .

  Therefore, as shown in Patent Document 5, the present applicant has proposed a side groove block that can transmit sound and vibration to a pedestrian and a driver when the vehicle abnormally approaches the sidewalk.

  FIG. 9 is a perspective view showing a schematic shape of the side groove block, and FIG. 10 is a schematic cross-sectional view showing a usage state of the side groove block shown in FIG.

  Referring to these drawings, the side groove block 57 is configured around a trunk body 19 having a substantially rectangular parallelepiped shape. A cavity 20 is formed in the trunk body 19 so as to penetrate in the longitudinal direction. The cavity 20 is formed for draining rainwater or the like flowing from a roadway or the like at the time of installation. Further, the upper surface portion of the trunk body 19 is configured to incline from the roadway side to the sidewalk side in the width direction. The corners on the sidewalk side of the upper surface portion 21 are formed with recesses 22 that fit into a part of the walking road boundary block 33 up to both ends in the longitudinal direction.

  In addition, slits 64 formed so as to reach the cavity 20 from the upper surface portion 21 are formed in the upper portion of the cavity 20 so as to extend to both ends in the longitudinal direction of the trunk body 19. Further, among the upper surface portion 21 divided by the slits 64, a plurality of protrusions 63 a and protrusions 63 b formed at predetermined intervals in the longitudinal direction of the trunk body 19 are formed on the roadway side portion with respect to the trunk body 19. It is integrally formed.

  At the time of installation, as shown in FIG. 10, the trunk body 19 is installed on the basic crushed stone 27 via the leveling mortar 30. On the roadway side, the roadway asphalt 29 is constructed on the basic crushed stone 28 so that the surface of the upper surface portion 21 and the upper surface thereof are aligned. On the other hand, on the sidewalk side, a sidewalk asphalt 32 is constructed on the basic crushed stone 31, and the pedestrian boundary block 33 is fitted in the recess 22 of the trunk body 19 at the boundary with the trunk body 19. It has been.

  FIG. 11 is a schematic perspective view showing a use state when the side groove block 57 is installed as in the cross-sectional view shown in FIG.

Referring to the drawing, it is assumed that the truck 65 abnormally approaches the sidewalk side by driving aside on the roadway asphalt 29 on the roadway side. In this case, the front wheel tire of the track 65 passes above the side groove block 57. Then, the tire of the track 65 gets over the protrusion 63 of the side groove block 57. At this time, a unique contact sound due to the shape of the protrusion 63 is generated. Then, a child 66 or the like walking on the sidewalk asphalt 32 is alerted to the track 65 by this warning sound, and it becomes possible to avoid danger in advance. This warning sound is transmitted to the driver of the truck 65 together with the vibration at the time of getting on, and particularly, the driver is alerted to an abnormal approach to the sidewalk during drowsy driving, and the safety is further improved.
Japanese Patent No. 2896891 Japanese Utility Model Publication No. 2-97479 JP-A-11-217803 Japanese Utility Model Publication No. 2-337989 JP 2006-169854 A

  The side groove block as described above is sufficient as a configuration for generating and transmitting a warning sound and vibration, but the protrusion 63 is formed so as to protrude on the upper surface portion 21 of the side groove block 57. Therefore, the durability against wear may not be sufficient. Especially in cold regions, snow removal work on the road with snow removal plates may be done in winter. In this case, since the side groove block itself is at the end of the road, it can be said that the influence thereof is small, but it can be said that the protrusion is easily worn.

  In addition, in order to form the protrusion, it is necessary to form a groove corresponding to the protrusion on the conventional mold for manufacturing the side groove block, and it is not easy to modify the mold.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a side groove block that improves the durability of a portion where a warning sound or vibration occurs and is easy to manufacture.

  In order to achieve the above object, the invention according to claim 1 is a side groove block installed at the boundary between a roadway and a sidewalk, has a substantially rectangular parallelepiped shape, and has a cavity penetrating in the longitudinal direction thereof. In addition, a trunk body that is arranged so that the upper surface portion thereof is aligned with the upper surface of the roadway, and a portion of the upper surface portion that is recessed, and at least a portion of the remaining portion of the upper surface portion crosses the longitudinal direction. A recess formed so as to be positioned, and an opening in which the lower position and a cavity are inserted in the bottom surface portion of the recess, and the recess has a trapezoidal shape in the shape of an isosceles trapezoid on the sidewalk side. An angle formed between each side of the isosceles trapezoidal shape and a direction orthogonal to the longitudinal direction is formed with the upper base, which is the shorter side of the shape, facing in the longitudinal direction. 10 °.

  If comprised in this way, when a vehicle approaches the sidewalk side, a tire will pass at least one part of a remainder. Moreover, the rainwater which flowed into the recessed part flows out to the cavity through the opening. Furthermore, at least a part of the remaining portion and a portion corresponding to the side of the recessed vehicle on the traveling direction side is inclined toward the traveling direction.

  According to a second aspect of the present invention, in the configuration of the first aspect of the invention, the area of the opening increases from the upper surface portion toward the cavity.

  If comprised in this way, opening will become a cross-sectional shape which spreads toward a cavity.

  As described above, according to the first aspect of the present invention, when the vehicle approaches the sidewalk, the tire passes at least a part of the remaining portion, so that a unique contact sound and vibration are generated. Therefore, the pedestrian and the driver are alerted, and safety is improved. Further, since the remaining portion is aligned with the upper surface of the roadway, the remaining portion is excellent in durability and is less affected by the work of the snow removal plate in winter. Furthermore, since rainwater that has flowed into the recess flows out into the cavity through the opening, rainwater or the like hardly remains in the remaining portion or the recess, so that the risk of mud splashing or slipping by the traveling vehicle is reduced. Furthermore, since at least a part of the remaining portion, which corresponds to the side of the recessed vehicle in the traveling direction, is inclined toward the traveling direction, the contact noise caused by the tires of the vehicle entering the sidewalk side is increased. To do.

  In addition to the effect of the invention of the first aspect, the opening according to the present invention has a cross-sectional shape that widens toward the cavity. improves.

  FIG. 1 is a schematic perspective view showing a use state of a side groove block according to the first embodiment of the present invention, and FIG. 2 is an enlarged sectional view taken along line II-II shown in FIG.

  Referring to these drawings, the side groove block 17 is configured around a trunk body 19 having a substantially rectangular parallelepiped shape, and the trunk body 19 is formed with a cavity 20 penetrating to both ends in the longitudinal direction. ing. In the side groove block 17 according to this embodiment, a portion corresponding to the slit 64 in the side groove block 57 of FIG. 9 shown as the conventional example is not formed, and the upper surface portion 21 is entirely closed. It is in the state.

  The trunk body 19 is installed on the basic crushed stone 27 through the leveling mortar 30. On the roadway side, the roadway asphalt 29 is constructed on the basic crushed stone 28 so that the upper surface thereof is aligned with the surface of the upper surface portion 21 of the side groove block 17. On the other hand, on the sidewalk side, a sidewalk asphalt 32 is constructed on the basic crushed stone 31, and the pedestrian boundary block 33 is fitted in the recess 22 of the trunk body 19 at the boundary with the side groove block 17. It is attached.

  On the upper surface portion 21 of the trunk body 19, recesses 23 formed by a plurality of depressions having a rectangular shape in plan view are formed at regular intervals in the longitudinal direction of the trunk body 19. The upper surface portion 21 of the trunk body 19 is formed in an inclined state so as to descend from the roadway asphalt 29 toward the walking road boundary block 33. Accordingly, the bottom surface of the recess 23 is similarly inclined to the walking road boundary block 33 side. And the opening which consists of the position by the side of the pedestrian road boundary block 33 of the recessed part 23, ie, the part corresponded in the downward position of the recessed part 23, and the cavity 20 is formed. As shown in FIG. 2, the round hole 24 has a cross-sectional shape in which the opening area increases from the bottom surface of the recess 23 toward the cavity 20. This effect will be described later.

  Since the concave portion 23 is formed in the upper surface portion 21 of the trunk body 19 as described above, at least a part of the remaining portion 25 of the upper surface portion 21 where the concave portion 23 is not formed crosses the longitudinal direction of the trunk body 19. Will be located.

  Next, with reference to FIG. 1, it is assumed that the vehicle approaches the walking road boundary block 33 and the front wheel tire has entered in the direction indicated by the arrow. In this case, since the remaining portion 25 of the upper surface portion 21 of the trunk body 19 is formed in a direction crossing the longitudinal direction of the trunk body 19, the front wheel tire will get over this as it approaches the walking road boundary block 33. Become. As a result, abnormal contact sounds and vibrations are generated. Since the remaining portions 25 are present at regular intervals in the longitudinal direction, contact sounds and vibrations are continuously generated at regular intervals, which is a stable warning. This alerts pedestrians and drivers and improves safety.

  Next, the draining action of rainwater and the like in the side groove block according to this embodiment will be described.

  Rainwater or the like generated on the roadway asphalt 29 flows into the walking road boundary block 33 side due to the inclination of the roadway asphalt 29. The rainwater that has flowed flows into the recess 23 from the upper surface portion 21 of the trunk body 19. Since the upper surface portion 21 of the trunk body 19 is inclined so as to be lowered toward the walking road boundary block 33 as described above, rainwater that has flowed into the concave portion 23 is also collected on the walking road boundary block 33 side. Since the round hole 24 inserted into the cavity 20 is formed in this part, the rainwater flowing into the recess 23 is discharged into the cavity 20 through the round hole 24. Since the discharging action of the round hole 24 is always performed, there is no possibility that rainwater remains on the upper surface portion 21 and the concave portion 23 of the trunk body 19. Therefore, problems such as mud splash and slip due to the vehicle passing over the upper surface portion 21 of the trunk body 19 are also reduced. Further, since the round hole 24 is formed in such a shape that its cross-sectional area widens as it goes toward the cavity 20 as described above, foreign matters such as sand and dust flowing together with rainwater flowing into the recess 23 are also clogged in the round hole 24. Without being discharged into the cavity 20. Therefore, the cleaning effect on the upper surface portion 21 of the trunk body 19 is also preferable.

  Next, the durability of the upper surface portion 21 of the side groove block 17 according to this embodiment will be described.

  Referring to FIG. 2, the upper surface portion 21 of the trunk body 19 is configured to align with the upper surface of the roadway asphalt 29. Therefore, the protrusion as shown in the conventional example is not formed on the upper surface portion 21 from the alignment surface. Therefore, there is no need to worry about wear on the protrusion as in the conventional example. On the other hand, since the concave portion 23 is formed below the alignment surface, and the remaining portion 25 of the upper surface portion 21 becomes relatively higher than the bottom surface of the concave portion 23, the same warning as that of the protrusion shown in the conventional example. Sound and vibration can be generated.

  Further, when the snow removal plate 34 passes over the upper surface portion 21 of the trunk body 19 in the snow removal operation in the cold region, no protrusions or the like are formed on the upper surface portion 21, so that the upper surface portion of the snow removal plate 34 is formed. It can be said that there is no concern about 21 wear or the like.

  FIG. 3 is a schematic diagram for explaining the manufacturing advantages of the side groove block shown in FIG.

  Referring to the drawing, in (1), the cross-sectional shape of the upper mold 36 for manufacturing a normal side groove block 57 in which the concave portion 23 is not formed on the upper surface portion 21 of the side groove block 17 is as follows. It is shown. That is, the inner surface 37 of the upper mold 36 is a flat surface corresponding to the upper surface portion 21 of the side groove block 57.

  In (2), it is a side groove block 17 corresponding to the side groove block 57 as shown in FIG. 1, and the cross section of the upper mold 36 in the case where the concave portion 23 is formed on the upper surface portion 21. The shape is shown. A plate 38 corresponding to the concave portion 23 of the side groove block 17 is attached to the inner surface 37 of the upper mold 36. As a result, a recess 23 is formed in the upper surface portion 21 of the side groove block 17. That is, as the upper mold 36, the side groove block 17 can be easily manufactured only by attaching the plate 38 to the inner surface 37 of the mold for manufacturing a normal side groove block conventionally used. . Therefore, the shape of the concave portion 23 formed in the upper surface portion 21 can be made arbitrary by detaching the plate 38 having various forms from the mold 36.

  Thus, in the present invention, since the side groove block 17 can be easily manufactured using the existing upper mold 36, there is a great merit in terms of manufacturing the side groove block 17.

  FIG. 4 is a perspective view showing a schematic configuration of a side groove block according to the second embodiment of the present invention, and corresponds to FIG. 1 according to the previous embodiment.

  Since the description is basically the same as that according to the first embodiment, the difference will be mainly described.

  Referring to the figure, in this embodiment, the shape of recess 23 formed in upper surface portion 21 is greatly different. That is, the concave portion 23 has a trapezoidal shape such as a plan view. And it arrange | positions so that the upper base may be located in the pedestrian road boundary block 33 side, and the several recessed part 23 is formed at predetermined intervals with respect to the longitudinal direction of the block 17 for side grooves. Both sides of the trapezoidal shape of the recess 23 are inclined by an angle α with respect to a direction orthogonal to the longitudinal direction of the side groove block 17. The angle α is preferably 5 to 10 °. Therefore, when the front wheel tire of the vehicle travels in the direction of the arrow in the figure, it rides on the remaining portion 25 defined by the side of the recess 23 on the traveling direction side. At this time, since the side is inclined by the angle α, it is possible to expect an increase in contact sound or the like due to the tire as compared with the one according to the previous embodiment shown in FIG.

  Further, since the round hole 24 is arranged on the upper bottom side of the concave portion 23 in a trapezoidal shape in plan view, rainwater flowing into the concave portion 23 can be intensively discharged into the cavity 20 of the side groove block 17.

  FIG. 5 is a perspective view showing a schematic configuration of a side groove block according to the third embodiment of the present invention, and corresponds to FIG. 1 according to the first embodiment.

  Since this embodiment is basically the same as that according to the first embodiment, the difference will be mainly described.

  Referring to the drawing, the recesses 23 formed in the upper surface portion 21 of the side groove block 17 are rectangular in plan view and are arranged at regular intervals, and the plan view connecting between the rectangular portions 40. It is comprised from the rectangular connection part 41a and the connection part 41b. As a result, the remaining portion 25 of the upper surface portion 21 is further divided, and it is possible to expect generation of a more specific warning sound and vibration for the tire entering in the direction of the arrow.

  FIG. 6 is a partial perspective view showing a schematic structure of a side groove block according to a fourth embodiment of the present invention.

  Referring to the drawing, the upper surface portion 21 of the side groove block 17 is not an inclined surface as in the previous embodiments, but a horizontal flat surface. The recess 23 has a rectangular flat plate shape, and an elongated hole 43 that is inserted into the cavity 20 is formed as an opening on the recess 22 side of the flat surface 44. Since the flat surface 44 of the recess 23 is not inclined, the drainage efficiency of rainwater is slightly reduced. However, since a long hole 43 having a large opening area is formed at a position below the rainwater, the rainwater remains in the recess 23. It becomes possible to discharge into the cavity 20 without causing it. The effect of generating a warning sound or vibration due to the approach of the vehicle is almost the same as that according to the first embodiment.

  FIG. 7 is a partial perspective view showing a schematic shape of a side groove block according to the fifth embodiment of the present invention, and corresponds to FIG. 6 according to the fourth embodiment.

  Since the side groove block is basically the same as that shown in FIG. 6, the difference will be mainly described.

  Referring to the figure, the shape of recess 23 is different from that of FIG. That is, the bottom of the recess 23 is an inclined surface 46 that is inclined toward the recess 22. Since the depth of the recess 23 on the road side is slightly shallower, a warning sound or the like at the start of entry of the vehicle is slightly reduced, but the drainage effect of rainwater flowing into the recess 23 is further improved.

  FIG. 8 is a partial perspective view showing a schematic shape of a side groove block according to the sixth embodiment of the present invention, and corresponds to FIG. 6 according to the fourth embodiment.

  Even in this embodiment, the difference will be mainly described.

  Referring to the figure, the shape of recess 23 is different, and it is configured by inclined surface 47a and inclined surface 47b that incline so that the bottom portion thereof becomes lower toward the center from the position on the road side and sidewalk side. . An elongated hole 43 that passes through the cavity 20 is formed as an opening at the center. As a result, the size of the warning sound or the like is about the middle between the fourth embodiment and the fifth embodiment, but the drainage efficiency of rainwater or the like flowing into the recess 23 is maximized.

  In each of the above embodiments, the shape of the concave portion is specified, but other shapes may be used in a plan view, a depth direction, and the like, and the interval between the concave portions may be arbitrarily set.

  In each of the above-described embodiments, the side groove block without a slit is targeted, but the present invention can be similarly applied to a side groove block having a slit. In this case, it is preferable to provide a recess on at least the roadway side of the upper surface portion divided by the slit.

  Furthermore, in each of the above-described embodiments, the opening through which the concave portion and the cavity are inserted is specified, but the number, shape, position, and the like may be arbitrarily set. Moreover, the cross-sectional shape does not necessarily have to expand toward the cavity.

  Furthermore, in each of the above-described embodiments, the trunk body is an integral type including the upper surface portion. For example, the trunk main body includes a gate-type side groove block and a side groove block provided with an upper lid (fixed type, separation type). Can be applied similarly. That is, the side groove block of the present application includes such a side groove block.

  Furthermore, in each of the above-described embodiments, the cross-sectional shape of the cavity formed in the trunk body is specified, but it goes without saying that other cross-sectional shapes such as an oval shape and a rectangular shape may be used.

  Furthermore, in each of the embodiments described above, the pedestrian road boundary block is separate from the side groove block, but can be similarly applied to a side groove block in which these blocks are integrated. In this case, the pedestrian road boundary block may be integrated with the trunk main body, or may be integrated with the upper lid attached to the main body.
