Description

  The present invention relates to a curved side groove and a side groove structure installed on a curved road surface such as a road or a parking lot.

The side groove provided on the road surface is mainly made of concrete, but a metal side groove that can be suitably installed on a curved road surface is also known (for example, Patent Document 1).
The metal side groove of Patent Document 1 is composed of a connection body of a plurality of metal segments, and each segment has a groove main body that forms a water channel and a water passage opening on the road surface, and water from the water passage to the road surface. The groove body is formed in a straight line, both end portions in the longitudinal direction of the groove body are formed obliquely with respect to the longitudinal direction, and the water passage portion is the length of the groove body. It is formed in a curved shape with respect to the direction.

  Since the side groove formed by connecting a plurality of curved segments having the curved water passage portion is generally curved as a whole, it can be suitably installed in a curved place. On the other hand, a straight side groove in which a plurality of straight segments having a straight water passage portion are connected is installed at a straight place. At the boundary between the curved location and the straight location, the end of the curved segment and the end of the straight segment are connected, and the side groove structure at the location from the straight to the curved by connecting the curved side groove and the straight side groove. You can build your body. At this time, the curved segment and the straight line segment are connected so that the end of the water passing portion of the curved segment and the end of the water passing portion of the straight line segment coincide.

In the straight line segment used in Patent Document 1, when the curved segment and the straight line segment are connected, the end of the water flow portion of the curved segment and the end of the water flow portion of the straight line segment coincide with each other. As described above, the water passing portion is disposed relatively near the center. That is, it can be said that the straight line segment disclosed in Patent Document 1 is an exclusive product of the curved line segment disclosed therein.
However, when the curve segment of Patent Document 1 is connected to a straight line segment that is not a dedicated product for the curve segment of Patent Document 1, there is a problem that a step is generated at the boundary between the two.

Specifically, concrete segments 7 (concrete side grooves) as shown in FIGS. 11 and 12 are conventionally used as straight segments that are not exclusive products of Patent Document 1. The concrete segment 7 is composed of a groove member 71 having a top surface that is linear in top view and substantially U-shaped in cross section, and a concrete lid member 72 that closes the opening of the concrete groove member 71. . A curbstone 721 that extends linearly in the longitudinal direction of the groove member 71 protrudes from the center of the lid member 72, and the lid member 72 at one base of the curbstone 721 has a plurality of leads that lead to the groove member 71. The water flow holes 74 are formed along the curb portion 721 at a predetermined interval. The water passage hole 74 is disposed on the extension line of the inner surface 711 a of the one side wall portion 711 of the groove member 71 or in the vicinity of the inner side of the extension line.
When the curved segment 9 is connected to the concrete segment 7 so that the water passage portion 94 of the curved segment 9 of Patent Document 1 matches the water passage hole 74 of the concrete segment 7 as shown in FIG. In addition, a side groove structure in which the inner surface 911a of one side wall portion 911 of the groove main body 91 of the curved segment 9 and the inner surface 711a of one side wall portion 711 of the concrete segment 7 do not coincide is obtained. Therefore, the inner surface is discontinuous at the boundary between the curved segment 9 and the concrete segment 7, and a step is formed between the inner surface 911 a of one side wall portion 911 of the curved segment 9 and the end surface 71 b of the concrete groove member 71. D is generated. When such a level difference D is generated, mud and the like are easily deposited there. Mud accumulated in the channel is removed by blowing high-pressure water from one direction along the longitudinal direction of the channel using a high-pressure washing machine at the time of maintenance. It may not be removed with high-pressure water sprayed from one direction.

The curved side groove | channel 1 of this invention is a metal side groove | channel (for example, steel), and can be installed in the curved place where the roadway and the sidewalk are curving.
As shown in FIG. 1, the curved side groove 1 is configured by connecting ends of a plurality of curved segments 2 having a required length. In FIG. 1, the curved side groove 1 composed of four curved segments 2 is illustrated, but the number of segments 2 constituting the curved side groove 1 is not particularly limited, and may be two or three. Five or more may be sufficient.
Each curve segment 2 is formed such that the opening angle at both ends is a required angle. In the illustrated example, the opening angle at both ends of each curve segment 2 is about 22.5 degrees so that the curve-side groove 1 constituted by the connection of the end portions of the curve segment 2 is about 1/4 circle as a whole. Is set to But the opening angle of the both ends of the segment 2 for curves is suitably set according to the number of segments to connect, the curvature of the curve part to install, etc.

As shown in FIGS. 2 to 5, the curved segment 2 includes a groove main body 3 that constitutes a water channel, and a flow passage that guides the water on the road surface from the water outlet to the groove main body 3 by projecting the water inlet to the road surface. And water part 4. Preferably, the curve segment 2 is symmetrical with respect to the longitudinal center line (IV-IV line in FIG. 2).
The groove main body 3 and the water flow portion 4 are set in the longitudinal direction in one direction. Both ends in the longitudinal direction of the groove body 3 are cut so that the cut surfaces are oblique with respect to the longitudinal direction. More specifically, both ends in the longitudinal direction of the groove body 3 are cut so that the cut surface at one end and the cut surface at the other end are acute angles in the horizontal plane. Therefore, the curve segment 2 has a substantially trapezoidal shape in a plan view shown in FIG. As described above, when the opening angle at both ends of the curved segment 2 is 22.5 degrees, each cut surface is 11.25 degrees with respect to the longitudinal direction.

The groove body 3 is formed of a tubular body having two side wall portions 31, 32, a lower surface portion 33, and an upper surface portion 34, and both ends thereof are opened. In the upper surface portion 34 of the groove body 3, an elongated opening communicating with the water passage portion 4 is formed in a curved shape with respect to the longitudinal direction.
As shown in FIGS. 2 and 5, the one side wall portion 31 of the groove body 3 is a curved surface formed in a curved shape (curved shape in plan view) with respect to the longitudinal direction. Specifically, one side wall portion 31 of the groove body 3 is formed in a curved shape in the same direction as the curve of the water passage portion 4 (the same direction as the curve means that the direction in which the curve swells is the same). Preferably, it is formed in a curved shape having the same direction and the same curvature as the curved line of the water passing portion 4. On the other hand, the other side wall part 32 of the groove body 3 is a flat surface formed linearly (in a plan view) in the longitudinal direction. One side wall 31 of the groove body 3 is preferably a side wall located on the roadway side when the curved segment 2 is installed, and the other side wall 32 of the groove body 3 is located on the sidewalk side when installed. It is preferable that it is a side wall part to perform. The lower surface portion 33 and the upper surface portion 34 of the groove body 3 are flat surfaces and are arranged in parallel to each other. One side wall portion 31 and the other side wall portion 32 of the groove body 3 are interposed between the lower surface portion 33 and the upper surface portion 34 substantially vertically.

The lower surface portion 33, the one side wall portion 31, the other side wall portion 32, and the upper surface portion 34 may be integrally formed by bending a single metal plate. But since one side wall part 31 is a curved surface, it is preferable to form at least one side wall part 31 with another metal plate from a viewpoint of workability. In the illustrated example, the lower surface portion 33, the other side wall portion 32, and the upper surface portion 34 are integrally formed by bending a single metal plate into a substantially U-shape, and one side wall portion 31 is separately formed. The metal plate is formed from a curved metal plate. And the groove main body 3 is comprised by adhering the lower end of one side wall part 31 which consists of this curved metal plate to the front-end | tip of the lower surface part 33 which consists of a substantially U-shaped metal plate by a joining means. In the present invention, the joining means typically includes welding, but riveting, screwing, or the like can also be used.
Further, the tip of the upper surface portion 34 is formed in a curved shape, but does not contact the inner surface 31a of the one side wall portion 31, and there is a gap between the tip of the upper surface portion 34 and the one side wall portion 31. Is provided. This gap corresponds to the elongated opening communicating with the water flow portion 4.

The water flow portion 4 is composed of a pair of water flow plates 41 and 42 arranged in parallel at a required interval. That is, the water flow portion 4 is a space between the pair of water flow plates 41 and 42. The pair of water flow plates 41, 42 extend to both ends in the longitudinal direction of the groove body 3, and are arranged in parallel with the gap. The pair of water flow plates 41 and 42 are curved surfaces formed in a curved shape (curved shape in plan view) with respect to the longitudinal direction, and preferably in the same direction and the same as the curved shape of the one side wall portion 31. It is formed in a curved shape of curvature.
One water flow plate 41 is disposed along the upper edge of one side wall portion 31 constituting the groove main body 3, and the other water flow plate 42 is disposed along the tip of the upper surface portion 34 constituting the groove main body 3. Has been placed. One water flow plate 41 may be formed of a curved metal plate that is separate from the one side wall portion 31, and the curved metal plate may be fixed to the upper edge of the one side wall portion 31 by a joining means. However, preferably, as shown in FIGS. 3 and 4, the one water flow plate 41 and the one side wall portion 31 are integrally formed from one curved metal plate. That is, one water flow plate 41 is formed by projecting one side wall 31 upward from the upper surface 34. The other water flow plate 42 may be formed integrally with the upper surface portion 34, but since it is a curved surface, from the viewpoint of workability, the other water flow plate 42 is preferably the upper surface portion 34. It is formed of another metal plate. In the illustrated example, the other water flow plate 42 is formed of a curved metal plate that is separate from the upper surface portion 34, and is configured by fixing the lower end of the curved metal plate to the tip of the curved upper surface portion 34 by a joining means. Has been.

  As shown in FIGS. 2 and 5, the curved segment 2 as described above has a water passage portion 4 extending in a curved shape over the entire longitudinal direction of the groove body 3. Furthermore, the one side wall portion 31 of the groove body 3 also extends in a curved shape over the entire longitudinal direction of the groove body 3. And the inner surface of one water flow board 41 which comprises the water flow part 4 exists in the same plane as the inner surface 31a of the one side wall part 31 of the groove | channel main body 3. As shown in FIG. For this reason, the water-permeable part 4 and the inner surface 31a of one side wall part 31 are adjoining over the whole longitudinal direction of the groove main body 3 by planar view. That is, the water flow part 4 is located on the extension line of the inner surface 31a of one side wall part 31, or the inner side vicinity of the extension line. The length L1 between the width direction center of the water flow part 4 and the extension line of the inner surface 31a of one side wall part 31 (refer FIG. 4) is 3 mm-30 mm, for example, Preferably it is 5 mm-20 mm. More preferably, the length L1 between the center in the width direction of the water flow portion 4 and the extension line of the inner surface 31a of the one side wall portion 31 is the center in the width direction of the water flow hole of the straight side groove and one side wall portion described later. It is formed to have the same length as that between the extension line of the inner surface.

In addition, although the space | interval (namely, width | variety of a water flow part) of a pair of water flow boards 41 and 42 is set to the narrow space | interval which does not have a trouble even if it does not install grating at the upper end part, In order to adjust the interval, a constriction body 51 may be provided. In the illustrated example, along the inner surface of the upper end portion of one water flow plate 41, a constriction body 51 made of a curved metal plate is fixed by a joining means. The narrowed body 51 functions as a reinforcing material that reinforces the water flow plate 41 and prevents the water flow portion 4 from being clogged. Specifically, in the illustrated example, the width of the water passage portion 4 is equal in the vertical direction, but when rainwater flows into the water passage portion 4 from the road, mud mixed in the rainwater is above the water passage portion 4. It collects in the part, it does not fall naturally, and the water passing part 4 is easily clogged at an early stage. For this reason, it is preferable that the width of the water flow portion 4 is small at the upper portion and large at the lower portion. In particular, the water flow portion 4 is formed so that its width gradually increases from the upper side to the lower side. More preferably. Thus, the water flow part 4 which becomes gradually wide as it goes below from the upper direction arrange | positions the water flow board 41 inclining with respect to the water flow board 42 extended in an up-down direction, (2) Water flow The plate 42 is disposed so as to be inclined with respect to the water flow plate 41 extending in the vertical direction, (3) the pair of water flow plates 41 and 42 are inclined with respect to each other, and are arranged in a C shape when viewed from the side surface, etc. It can form by the method of. However, inclining the water passage plate increases the cost from the viewpoint of workability. For this reason, by providing the narrowed body 51, it is possible to easily obtain the water passing portion 4 in which the width of the upper portion is smaller than the width of the lower portion, and early clogging of the water passing portion 4 can be suppressed.
Moreover, it is preferable that the some connection body 52 is provided between the pair of water flow boards 41 and 42 at predetermined intervals in the longitudinal direction. The coupling body 52 is fixed to the inner surfaces of the pair of water flow plates 41 and 42 by a joining means. When a load is applied to the curved segment 2, the pair of water flow plates 41, 42 may be deformed and the water flow portion 4 may be partially narrowed, but by providing the connecting body 52, The space | interval (width | variety of the water flow part 4) of a pair of water flow boards 41 and 42 can be hold | maintained.

  Further, in order to increase the strength of the groove body 3, the groove body 3 is preferably provided with reinforcing ribs 53 at appropriate positions in the longitudinal direction. In the illustrated example, two reinforcing ribs 53 are arranged at a predetermined interval along the width direction from the upper surface portion 34 to the other side wall portion 32, and are fixed to the groove body 3 by the joining means.

The curved segment 2 has flanges 54 provided at both ends in the longitudinal direction in order to connect the adjacent curved segments 2 to each other. The flange 54 is a flange 54 that extends in three directions from the opening edge excluding the lower surface portion 33 of the groove body 3. Strictly speaking, the flange 54 extending in three directions is cut out at a location corresponding to the water flow portion 4. The flange 54 is fixed to the one side wall portion 31, the other side wall portion 32, and the upper surface portion 34 of the groove main body 3 by a joining means. Further, through holes are formed at appropriate locations in the surface of the flange 54. This through hole is a hole for inserting a fastener (such as a bolt) to connect the flanges 54 of the adjacent curved segments 2. As shown in FIG. 1, the curved side groove | channel 1 is comprised by abutting the adjacent flange 54 and connecting both using fasteners, such as a volt | bolt and a nut.
Furthermore, the curve segment 2 has a bracket 55 provided at an appropriate location on the outer surface of the groove body 3 in order to fix the curve segment 2 on the basis. The curved segment 2 is fixed to the foundation via a bracket 55 by fixing means such as an anchor bolt.

6 is a schematic reference view of a side groove structure A composed of the curved side groove 1 and the straight side groove 6, and FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. In FIG. 7, the water flow portion of the curved side groove and the water flow hole of the straight side groove are indicated by a two-dot chain line.
The curved side groove 1 and the straight side groove 6 are installed along the boundary between the roadway R and the sidewalk S, as shown in FIG. The curved side groove 1 is installed in a curved shape (arc shape in the illustrated example) where the roadway R and the sidewalk S are curved. The straight side groove 6 is installed in a place where the roadway R and the sidewalk S are straight.
The curved side groove | channel 1 consists of the connection body of the segment 2 for several curves as above-mentioned. Since one side wall portion 31 of the curved segment 2 is formed in a curved shape with respect to the longitudinal direction of the groove main body 3, the curved side groove 1 is formed at the boundary of each curved segment 2. The inner surface 31a is continuously curved. In the curved groove 1 of the present invention, the inner surface of one side wall portion 31 constituting the water channel is formed in a curved shape as a whole, so that no step is generated at the boundary (joint) of each curved segment 2. For example, when high-pressure water is sprayed from one direction along the longitudinal direction of the water channel during maintenance, the high-pressure water mainly travels in the longitudinal direction of the water channel while hitting the inner surface 31a of the one side wall 31. Since it is a continuous curve, high-pressure water flows smoothly. For this reason, mud in the water channel can be easily and reliably removed with high-pressure water. In addition, although the inner surface 32a of the other side wall part 32 is also continuous at the boundary between the curved segments 2, the inner surface 32a of the other side wall part 32 has a polygonal shape as a whole.
A curved curb B is provided on the upper surface 34 of the groove main body 3 of the curved groove 1 and along the other water passage plate 42. Therefore, the water flow portion 4 is disposed along one base end portion of the curb B on the roadway R.

The straight side groove 6 combined with the curved side groove 1 of the present invention may be a conventionally used one or may be a newly produced one. For example, the example using the concrete side groove conventionally used as the linear side groove | channel 6 is demonstrated.
The concrete straight side groove 6 is configured by connecting ends of a plurality of concrete segments 7. The concrete segment 7 is a groove member 71 having an opening on the upper surface having two side wall portions 711 and 712, and a groove member 71 constituting a water channel, and a curbstone portion 721 is provided on one base portion of the curbstone portion 721. A lid member provided with a water passage hole 74 and closing the upper surface opening of the groove member 71. Please also refer to FIG. The water passage hole 74 communicates with the upper surface opening of the groove member 71, and a plurality of water passage holes 74 are formed along one base portion of the curb portion 721. Further, the water passage hole 74 is disposed on the extension line of the inner surface 711 a of the one side wall portion 711 of the groove member 71 or in the vicinity of the inner side of the extension line. The length L2 between the width direction center of the water flow hole 74 and the extension line of the inner surface 711a of one side wall part 711 is, for example, 3 mm to 30 mm, and preferably 5 mm to 20 mm.

A side groove structure A composed of the curved side groove 1 and the straight side groove 6 is obtained by connecting the end of the adjacent curved segment 2 and the concrete segment 7 (straight line segment).
For example, as shown in FIG. 7, the flange 54 of the curved segment 2 located at one end of the curved groove 1 is attached to the end face of the groove member 71 of the concrete segment 7 located at one end of the straight groove 6. The curved side groove 1 and the straight side groove 6 are connected by being fixed by a fixing means such as.
In the curved side groove 1 of the present invention, the one side wall portion 31 and the water passage portion 4 of the groove main body 3 are formed in a curved shape with respect to the longitudinal direction of the groove main body 3, respectively. By connecting, the water flow portion 4 coincides with the water flow hole 74 of the straight side groove 6 (the water flow portion 4 and the water flow hole 74 are continuous from the curved side groove 2 to the straight side groove 6), and the curved side groove 1 A side groove structure A in which the inner surface 31a of one side wall 31 and the inner surface 711a of one side wall 711 of the straight side groove 6 are continuous is obtained.

In such a side groove structure A, the water flow portion 4 and the water flow hole 74 are continuous (therefore, the curb B installed above the curved side groove 1 and the curb portion 721 of the straight side groove 6 are also continuous). The drainage function is not hindered, and the appearance is good.
In the side groove structure A, the inner surface 31a of one side wall 31 of the curved side groove 1 and the inner surface 711a of one side wall 711 of the straight side groove 6 are continuous at the boundary between the curved side groove 1 and the straight side groove 6. When high-pressure water is sprayed along the longitudinal direction of the water channel, the high-pressure water mainly flows smoothly from the inner surface 711a of one side wall portion 711 of the straight side groove 6 to the inner surface 31a of one side wall portion 31 of the curved side groove 1. Will come. For this reason, the side groove structure A of the present invention can easily and reliably remove mud and the like in the water channel with high-pressure water.
In addition, the side groove structure A has an inner surface of the other side wall portion 32 of the curved side groove 1 and an inner surface of the other side wall portion 712 of the linear side groove 6 at the boundary between the curved side groove 1 and the straight side groove 6. The inner surface (the bottom surface of the groove body 3 of the curved groove 1) and the bottom surface of the linear groove 6 are also continuous.

In addition, the curved side groove | channel and the side groove | channel structure A of this invention are not restricted to what was shown to the said embodiment, A design change can be suitably carried out in the range which this invention intends.
