Therefore, basically, it is not considered that the pavement is greatly worn, and it is not considered that the plow advances obliquely.

Japanese Patent Laid-Open No. 2003-253609

  The present invention has been made to solve such a problem, and can be used for a long time without any trouble even when blades (such as a soil removal board, a snow removal board, or a plow) frequently come and go. It is a main object to provide a blade guiding member for a concrete block that can be used without any trouble even when the blade advances obliquely.

  The present invention adopts the following means in order to achieve the above-mentioned object.

The blade guide member according to the present invention is:
In the blade guide member attached to the concrete block,
Side plates arranged vertically and longitudinally on the side or top surface of the concrete block;
A blade guide plate extending on the side plate at an interval in the longitudinal direction,
The blade guide plate is formed so as to become lower as it is separated from the side plate, and a part or all of the upper side is formed in a curved shape.

  According to the blade guide member according to the present invention, a concrete block having a blade guide plate extending to the side of the concrete block by being attached to a side surface or an upper surface of the concrete block such as an existing gutter block or a culvert block is provided. can do. As a result, it is possible to prevent the blade from the snowplow or the bulldozer from directly colliding with the concrete block and damaging the concrete block or giving an unintended impact to the snowplow. Further, since the blade guide plate of the blade guide member according to the present invention is formed in a curved shape, the angle at which the blade collides with the blade guide plate when the road surface is worn can be made an obtuse angle and moves smoothly. It can be made easy. Therefore, it is possible to reduce the impact when shifting from the road surface to the blade guide plate. Moreover, since the impact which collides with a blade guide plate can be relieved, abrasion of a blade guide plate can be reduced and the lifetime of a blade guide member can be lengthened. Further, if the upper side is adjacent to the side plate or has a convex curve in the vicinity, the possibility that the blade directly collides with the concrete block can be reduced.

  In the blade guide member according to the present invention, the upper side of the blade guide plate may be formed in an arc shape with a recessed center. By adopting such a configuration, the blade guide plate of the blade guide member according to the present invention is formed in a curved shape, so that when the road surface is worn, the angle at which the blade collides with the blade guide plate is obtuse. Therefore, it can be easily moved smoothly. Therefore, it is possible to reduce the impact when shifting from the road surface to the blade guide plate. Moreover, since the impact which collides with a blade guide plate can be relieved, abrasion of a blade guide plate can be reduced and the lifetime of a blade guide member can be lengthened.

  Furthermore, in the blade guide member according to the present invention, the blade guide plate may include a convex portion protruding upward in the vicinity of the side plate. By adopting such a configuration, the possibility that the blade directly collides with the concrete block can be reduced. Further, the possibility that the blade collides with the side plate can be reduced. Furthermore, even when the blade enters obliquely, the blade is lifted higher, so that the possibility of the blade colliding with the side plate can be reduced. Further, even when the blade guide plate is worn, it can be used until it is worn to the height of the upper end side of the side plate, so that the life of the blade guide member can be extended.

  Furthermore, in the blade guide member according to the present invention, the upper side of the blade guide plate may be formed in a straight line instead of an arc shape with a recessed center. In the blade guide plate provided with a convex portion protruding upward in the vicinity of the side plate, the same effect can be obtained even if the upper side is a straight line.

  Furthermore, the blade guide member according to the present invention may further include a block protection unit that is connected to the side plate and is disposed on the upper surface side of the concrete block. By adopting such a configuration, it is possible to reduce the possibility that the concrete block will be damaged even when the blade falls on the upper surface of the concrete block after the blade has passed over the blade guide plate.

  Further, in the blade guide member according to the present invention, the blade guide plate may be formed to be rotatable with respect to the block protection part. By adopting such a configuration, the position of the blade guide plate can be changed from the road surface side to the inside of the concrete block, so that the road surface rolling under the blade guide member can be easily performed.

  Furthermore, in the blade guide member according to the present invention, a drainage through hole may be formed in one or both of the side plate and the bottom plate. By adopting such a configuration, it is possible to prevent the drainage performance from being impaired even when the blade guide member is attached to the road surface having the water-permeable pavement.

  Furthermore, a side groove block with a blade guide member according to the present invention includes the blade guide member described above and a side groove block made of concrete. By adopting such a configuration, a side groove block having the above-described effects can be provided.

  Furthermore, according to the blade guide member and the side groove block according to the present invention, it is possible to provide the blade guide member and the side groove block that can be used for a long time without any trouble even when the blades frequently come and go.

  Hereinafter, embodiments of the blade guide member 100 and the concrete block 90 to which the blade guide member 100 is attached will be described in detail with reference to the drawings. It should be noted that the embodiments and drawings described below exemplify a part of the embodiments of the present invention, and are not used for the purpose of limiting to these configurations, and do not depart from the gist of the present invention. Can be changed as appropriate. Corresponding components in the drawings are given the same or similar reference numerals.

(First embodiment)
FIG. 1 is a perspective view of the blade guide member 100 and the concrete block 90 according to the first embodiment. As shown in FIG. 1, the blade guide member 100 according to the first embodiment is erected vertically and has a side plate 10 fixed to a side surface of the concrete block 90 and a lower upper side 20 a in a direction away from the side plate 10. The blade guide plate 20 is formed as described above.

  The side plate 10 is made of a metal plate material, and a plurality of screwing through holes 11 are formed so that the side plate 10 can be attached to the concrete block 90 with a screwing member 80 such as a bolt. Although the width in the height direction of the side plate 10 is not particularly limited, it is preferable that the side plate 10 be manufactured to a height of 3 cm to 6 cm. This is because the pavement surface may be cut by 3 cm or more in one season by a snowplow in a snowfall area. In the first embodiment, the length in the longitudinal direction is the same as the length of the concrete block 90. However, the length in the longitudinal direction is shorter than the length of the concrete block 90 and attached to a part of the concrete block 90. You may form in the length made.

  A plurality of blade guide plates 20 are attached at intervals in the longitudinal direction so as to be orthogonal to the side plate 10. As shown in FIG. 2, the blade guide plate 20 is formed obliquely so as to become lower as the distance from the side plate 10 increases, and the upper side 20a is formed in a curve so that the center is lowered. Although the curved line is formed in an arc shape in FIG. 2, the curved line is not particularly limited, and may be a curved line having a low center and a smooth curve. Further, the upper side 20 a of the blade guide plate 20 is provided so as to be at the same height as the upper side of the side plate 10 at the coupling position with the side plate 10. The width between the adjacent blade guide plates 20 is preferably about 20 to 30 cm.

  As shown in FIG. 3, the blade guide member 100 manufactured in this way is attached to a concrete block 90, for example, a side surface of a side groove block through a screwing through hole 11. The concrete block 90 to which the blade guide member 100 is attached in this way is paved with asphalt or concrete 95 to the same height as the upper surface 90a of the concrete block 90, and the blade guide member 100 remains partly or almost entirely underground. Buried in

  In the concrete block 90 laid in the ground in this way, the blade guiding member 100 does not particularly function before the road surface is worn. However, when the road surface is worn by the blade, the blade guide plate 20 is harder than the asphalt, concrete or the like 95, so that the wear is suppressed low and the blade guide plate 20 is exposed on the road surface as shown in FIG. At this time, if the blade guide plate 20 is not present, the blade directly collides with the concrete block 90 and damages the concrete block 90, or the blade is caught by the concrete block 90 and a strong impact is applied to the blade side. Because the blade guide plate 20 exists, when the blade tries to cross the concrete block 90 along the ground, the blade is lifted upward along the blade guide plate 20 and collides with the side wall of the concrete block 90. The concrete block 90 can be traversed without any problem. Also, the blade guide plate 20 according to the present embodiment has an upper side 20a formed in an arc shape, so as shown in FIG. 4B, compared to the blade guide plate 220 in which the upper side 20a is formed in a straight line. Since the angle (part indicated by the arrow A) when approaching the blade guide plate 20 from the worn road surface becomes smooth, the impact applied to the blade can be reduced. The blade guide plate 20 itself is also worn by the blade. In this case, in the case of the blade guide plate 220 in which the upper side 20a is formed in a straight line, the blade guide plate 20 is often shaved unevenly due to a strong impact by the blade. However, since the blade guide plate 20 of the present embodiment has a smaller impact and is easier to slide than the blade guide plate 20, the blade guide plate 20 is less worn and the worn upper side 20 a tends to be smooth. Therefore, it can function as the blade guide plate 20 for a longer period, and the life can be extended.

  In the blade guide member 100 according to the first embodiment, technical changes may be made as follows.

  In the blade guide member 100 according to the first embodiment, as shown in FIG. 5, the blade guide plate 20 of the blade guide member 100 may be arranged to extend about 1 cm or less above the upper surface 90a of the concrete block 90. Good. By adopting such a configuration, the blade guide plate 20 can be used until it is worn below the upper surface 90a of the concrete block 90 even if the blade guide member 100 is slightly worn by the blade. Therefore, the life of the blade guide member 100 can be extended.

  Further, in the blade guide member 100 according to the first embodiment, as shown in FIG. 6, a bottom plate 30 may be provided below the blade guide plate 20 by welding or the like. By adopting such a configuration, the blade guide plate 20 is fixed to the bottom plate 30 in addition to the side plate 10 and becomes stronger, and the life of the blade guide member 100 can be extended.

  Further, in the blade guide member 100 according to the first embodiment, all the blade guide plates 20 are formed to have the same thickness, but the thickness of each blade guide plate 20 may be different. In particular, the blade guide plate 20 is used in a portion where the blade passes frequently, or in a place where a person passes, so that the life of the blade guide plate 20 is extended or a large area is obtained when a person rides. Can be received at.

  Furthermore, in the blade guide member 100 according to the first embodiment, as shown in FIG. 7, the upper surface cover portion 21 may be provided so as to cover the upper surface 90 a of the concrete block 90. By adopting such a configuration, when the blade passes through the upper surface 90a of the concrete block 90, the possibility that the upper surface 90a of the concrete block 90 is worn or damaged can be reduced. Further, the upper surface cover portion 21 may be provided with the inner surface cover portion 22 so as to cover the inner surface 90b of the concrete block 90 as well.

  Furthermore, in the blade guide member 100 according to the first embodiment, the drainage holes 12 and 32 may be provided in the side plate 10 or the bottom plate 30. By adopting such a configuration, in the case of permeable pavement, even when draining through the drainage holes of the concrete block 90, the drainage can be performed at or near the site corresponding to the drainage holes of the concrete block 90. By providing the holes 12 and 32, the drainage function is not hindered.

  Furthermore, when the blade guide member 100 according to the first embodiment is attached to the concrete block 90, as shown in FIG. 8, the side wall of the concrete block 90 may be attached to a notch 90c partially cut away. By adopting such a configuration, it is possible to facilitate rolling of the road surface foundation and the road surface before paving before attaching the blade guide member 100.

The blade guide member 100 according to the second embodiment is different from the blade guide member 100 according to the first embodiment in that a convex portion 23 is provided on the upper side 20a in the vicinity of the side plate 10 of the blade guide plate 20. . Since the other points are the same as those of the blade guide member 100 of the first embodiment, description thereof is omitted. The technical change in the first embodiment can also be applied to the second embodiment.

  As described above, the blade guide member 100 according to the second embodiment includes, in the blade guide plate 20, an arc-shaped protrusion protruding above the upper end surface of the side plate 10 in the vicinity of the side plate 10 or adjacent to the side plate 10. Part 23. By adopting such a configuration, even when the convex portion 23 is worn away due to abrasion with the blade, it can be used until the convex portion 23 is scraped downward from the upper end surface of the side plate 10. The life of the guide member 100 can be extended. Further, since the blade is lifted slightly above the upper surface 90a of the concrete block 90 and the grating or gutter lid 96, the possibility of damaging the upper surface of the concrete block 90 and the grating or gutter lid 96 can be reduced. It also prevents the grating 96 and the side groove lid 96 from being rolled up. Furthermore, even when the blade enters obliquely, the blade is lifted further upward, so that the possibility that the left end and the right end of the blade collide with the side plate 10 can be reduced. Moreover, since a braid | blade falls smoothly by forming a convex part in arc shape, possibility that the upper surface 90a of the concrete block 90 will be damaged can be reduced.

  In the second embodiment, the upper side 20a of the blade guide plate 20 of the blade guide member 100 is formed in a concave shape, but may be formed in a straight line as shown in FIG.

The blade guide member 100 according to the fourth embodiment is of a type mainly molded integrally with the concrete block 90. As shown in FIG. 12, the blade guide member 100 according to the fourth embodiment has a side plate 10 erected substantially at the center of the bottom plate 30. The point that the blade guide plate 20 is attached to the side plate 10 is the same as in the fourth embodiment described above.

  The blade guiding member 100 is integrally attached to the upper surface 90a of the concrete block 90. By adopting such a configuration, the concrete block 90 can be integrated with the blade guide member 100 in advance, so that the concrete block 90 can be integrated with the blade guide member 100 in advance. Further, the side plate 10 can be used as it is as a receiving frame for the grating 96 or the lid 96 of the side groove. At this time, by forming the upper side 20a of the blade guide plate 20 at a position higher than the upper surface of the grating or side groove lid 96, it is possible to prevent the grating 96 and the side groove lid 96 from being rolled up. it can.

  In addition, this invention is not limited to each embodiment mentioned above, and it cannot be overemphasized that it can implement with a various aspect, as long as it belongs to the technical scope of this invention.
