Description

  The present invention relates to a gutter installed on a road surface such as a road or a parking lot. In particular, the present invention relates to a metal gutter.

  At present, concrete gutters are the mainstream. However, the side gutter made of concrete has a heavy weight, and is complicated to carry and carry on site, and requires a large-scale civil engineering work for repair and replacement, which causes problems in terms of construction period and cost. Therefore, in recent years, metal side grooves which are lighter than concrete side grooves but have high rigidity and are easy to construct have been used (for example, Patent Document 1).

  However, since this type of metal side groove has a structure in which a plurality of segments are connected in series, it can be installed only on a straight portion of the road surface. In other words, conventional metal side grooves cannot be installed in places where the road surface is curved so as to be seen at intersections and the like.

  Hereinafter, a first embodiment of a lateral groove according to the present invention will be described with reference to FIGS. As shown in FIG. 1, the side groove 1 according to the present embodiment is a metal side groove (made of steel in the present embodiment) installed along the boundary between the roadway R and the sidewalk S. Corresponding to S being curved, it can be installed in a curved shape (in this embodiment, an arc shape).

  As shown in FIG. 2, the side groove 1 is configured by connecting a plurality of segments each having a predetermined length. The segment includes a curved segment 2 and a straight segment 3. In this embodiment, the roadway R and the sidewalk S are bent at right angles, so that a plurality of segments connected at 90 degrees are connected. A straight line segment 3 is connected to both ends of the curved line segment 2. In the present embodiment, each segment 2 is formed so that the opening angle at both ends is 22.5 degrees, and four segments 2 are used in order to make a right angle. However, the angle of the segment 2 can be appropriately selected according to the site.

  As shown in FIGS. 3 to 5, the segment 2 includes a groove main body 10 constituting a water channel and a lid body 30 placed on the upper portion of the groove main body 10. The groove main body 10 and the lid body 30 are elongated in one direction, and both end portions in the longitudinal direction of the groove main body 10 and the lid body 30 are cut so that the cut surfaces are oblique with respect to the longitudinal direction. More specifically, both end portions of the groove main body 10 and the lid body 30 in the longitudinal direction are cut so that a cut surface at one end and a cut surface at the other end have an acute angle in a horizontal plane. Therefore, the segment 2 has a trapezoidal shape in plan view. In the present embodiment, as described above, since the opening angle at both ends of the segment 2 is 22.5 degrees, each cut surface is 11.25 degrees with respect to the longitudinal direction.

  The groove body 10 has a square tubular shape whose upper surface is opened except for both end portions. The groove body 10 is obtained by cutting a standard square steel material having such a shape into a predetermined length. That is, the groove body 10 includes a bottom portion 11 placed on a foundation formed by excavating a road surface, and side wall portions 12 rising from both side edges of the bottom portion 11, and further, from the upper end edge of the side wall 12. A pair of folded pieces 13 bent inward are provided. In this embodiment, the width of the bottom portion 11 is longer than the height of the side wall portion 12, but the height of the side wall portion 12 and the width of the bottom portion 11 are the same length, or the height of the side wall portion 12 is the same. It may be longer than the width of the bottom 11.

  The lid 30 includes a lid 31 that closes the opening 14 (opening between the pair of folded pieces 13) on the upper surface of the groove body 10, and a water passage 38 (so-called “drinking mouth” that stands up from the upper surface of the lid 31. )).

  The lid plate 31 has a slit 32 to guide rainwater passing through the water passage portion 38 to the groove body 10. The slit 32 is formed in a long shape along the longitudinal direction of the segment 2, but is formed in a curved shape, not a straight line along the longitudinal direction of the groove body 10 and the lid body 30. The slit 32 is formed from one end to the other end in the longitudinal direction of the lid plate 31.

  The lid plate 31 includes a first lid plate 33 on one side in the width direction across the water passage portion 38 and a second lid plate 34 on the other side in the width direction. The side edge on the second lid plate 34 side of the first lid plate 33 is formed in a curved shape, and the side edge on the first lid plate 33 side of the second lid plate 34 is also formed in a curved shape. . Both side edges are spaced apart from each other with a predetermined interval in the width direction of the cover plate 31. In the present embodiment, the opening between the side edge on the second lid plate 34 side of the first lid plate 33 and the side edge on the first lid plate 33 side of the second lid plate 34 constitutes the slit 32. Yes.

  The folded piece 35 hangs down from the side edge of the first lid plate 33 opposite to the second lid plate 34 and the side edge of the second lid plate 34 opposite to the first lid plate 33. ing. The folded piece 35 of the first lid plate 33 is in contact with the outer surface of the upper end portion of the one side wall portion 12 of the groove body 10 and is joined by welding, for example. The folded piece 35 of the second lid plate 34 abuts on the outer surface of the upper end portion of the other side wall portion 12 of the groove body 10 and is joined by welding, for example. Thus, the lid body 30 is joined and integrated with the groove body 10. However, the present invention is not limited to this, and the lid body 30 is placed on the groove body 10 and may be separable.

  The water flow portion 38 is composed of a pair of water flow plates 39 that are separated at a predetermined interval. As for the water flow part 38, the lower end edge of one water flow plate 39 is joined to the side edge of the first cover plate 33 on the second cover plate 34 side, and the lower end edge of the other water flow plate 39 is the second cover plate. By being joined to the side edge of 34 on the first lid plate 33 side, it is curved in plan view. The water flow portion 38 is formed from one end to the other end of the cover plate 31 by joining each of the pair of water flow plates 39 from one end to the other end in the longitudinal direction of the cover plate 31.

  In addition, although the space | interval of a pair of water flow board 39 is set to the narrow space | interval which does not have trouble even if it installs no grating in the upper end part, a pair of water flow board 39 is adjusted for the space | interval adjustment on it. The constriction body 40 is joined by welding, for example, along the inner surface of the upper end portion of at least one water flow plate 39.

  Further, the first lid plate 33 to which one water passage plate 39 is joined and the second lid plate 34 to which the other water passage plate 39 is joined are respectively connected to the groove main body 10 by the folded pieces 35 at the side ends. A sufficient pressure-resistant load from above cannot be obtained simply by bonding. Therefore, the connecting body 41 is interposed between the pair of water passing plates 39 at appropriate positions in the longitudinal direction of the water passing portion 38, and the connecting bodies 41 are respectively joined to the water passing plates 39 by welding, for example. The water flow plate 39 is integrated through a connecting body 41. In this embodiment, the connection body 41 is provided in four places including the both ends in the longitudinal direction of the water flow part 38. However, this is determined by the load from above. For example, when the vehicle is installed in a place where it passes upward, the number of connecting bodies 41 increases, and conversely, only humans pass above. In the case where it is installed in a different place, the number of the coupling bodies 41 is reduced.

  Further, in order to give strength to the lid plate 31 (each of the first lid plate 33 and the second lid plate 34), and thus to give strength to the entire lid body 30, reinforcement is performed at an appropriate position in the longitudinal direction of the lid body 30. Ribs 42 are arranged. The reinforcing rib 42 is disposed on the upper surface of the lid plate 31 along the width direction, and the reinforcing rib 42 is joined to the lid plate 31 and the water flow plate 39 by welding, for example, so that the reinforcing rib 42 passes through the lid plate 31. It joins over the water plate 39, and the deformation | transformation of the cover plate 31 and the fall of the water flow plate 39 are prevented suitably. The reinforcing rib 42 includes a first reinforcing rib 43 joined across the upper surface of the first lid plate 33 and the outer surface of one water passage plate 39, and the upper surface of the second lid plate 34 and the other water passage plate 39. It consists of the 2nd reinforcement rib 44 joined ranging over an outer surface. In the present embodiment, the reinforcing rib 42 is provided corresponding to a place where the coupling body 41 is disposed. The reinforcing ribs 42 are arranged radially. In addition, since the water flow part 38 is arrange | positioned in the location close | similar to the other side in the width direction of the cover body 30, the 1st reinforcement rib 43 is longer in the width direction of the cover body 30 than the 2nd reinforcement rib 44. It is a scale.

  In addition, the connection body 41 of the one end part in the longitudinal direction of the water flow part 38 among the connection bodies 41 has protruded partially from the water flow part 38 (projection part 41a). On the other hand, the connecting body 41 at the other end portion in the longitudinal direction of the water passing portion 38 is disposed in a recessed portion. This is because, when connecting a plurality of segments 2, the protruding portion 41 a of the connection body 41 at one end of the segment 2 is inserted between the other end portions of the pair of water flow plates 39 of the adjacent segment 2. This is to prevent the displacement of the segment 2 in the width direction.

  Here, the segment 2 includes flanges 50 at both ends in order to connect the adjacent segments 2 to each other. The flange 50 is a flange having a form that spreads in three directions from the opening edge except for the bottom 11 at both ends of the segment 2. Strictly speaking, however, the flange 50 extending in three directions is cut out at a portion corresponding to the slit 32. The flange 50 is joined to the opening edge of the segment 2 by welding, for example. A through hole 51 is formed at an appropriate location of the flange 50. Thereby, when the adjacent segments 2 are abutted, the opposing flanges 50 overlap and the through holes 51 coincide. Here, for example, by passing a bolt (not shown) and screwing a nut (not shown), the overlapping flanges 50 can be fastened, and adjacent segments 2 can be connected together. In addition, the part joined across the cover plate 31 and the water flow board 39 among the flanges 50 has the same function as the reinforcing rib 42.

  Further, the segment 2 includes a bracket 52 at an appropriate position on the outer surface of the groove body 10 in order to fix the segment 2 to the foundation. As shown in FIG. 1, the segment 2 is fixed to the base B by a fixing means such as an anchor bolt A via a bracket 52. And the curb C is arranged on the upper surface of the first lid plate 33, arranged along the water passage 38, and further grounded with soil or asphalt, and the water outlet 38a at the upper end of the water passage 38 is connected to the road surface. The side groove 1 is completed so as to be united.

  As described above, according to the side groove 1 according to the present embodiment, the water flow port 38a of the water flow portion 38 can be formed along the curb C arranged in a curved shape (in the present embodiment, an arc shape). That is, the metal side groove 1 can be installed in a curved place.

  In addition, only the water passage portion 39 is curved, and the groove main body 10 and the cover plate 31 are linear. Therefore, the manufacturing cost can be greatly reduced as compared with the case where the groove body 10 and the cover plate 31 are formed in a curved shape. This becomes conspicuous when a standard square steel material is used for the groove body 10.

  Next, a second embodiment of the side groove according to the present invention will be described with reference to FIGS. Note that the side groove 1 according to the present embodiment has the same basic configuration as the side groove 1 according to the first embodiment. Therefore, the same reference numerals are given to the same or equivalent configurations, and the description in the first embodiment can be used for the description.

  The side groove 1 according to the present embodiment is a so-called variable (free) gradient type side groove, and is formed with concrete that constitutes the bottom surface of the water channel at the site to form a necessary gradient as the water channel. The side groove 1 according to the present embodiment is also a metal side groove (made of steel in the present embodiment) installed along the boundary between the roadway R and the sidewalk S, and the roadway R and the sidewalk S are curved. As shown in FIG. 6, it can be installed in a curved shape (in the present embodiment, an arc shape).

  As shown in FIGS. 7 to 9, the segment 2 includes a groove main body 10 constituting a water channel and a lid body 30 placed on the upper portion of the groove main body 10. Unlike the side groove 1 according to the first embodiment, the side groove 1 according to the present embodiment is detachable from the groove body 10 in terms of placing concrete in the groove body 10. Specifically, the groove body 10 includes a flange 17 along the upper edge of the side wall portion 12, and when the lid body 30 is placed on the groove body 10, the width of the flange 17 and the lid plate 31. Side end portions in the direction (the cover plate 31 according to the present embodiment does not include the folded piece 35) overlap each other. A through hole (not shown) is formed in each of the flange 17 and the side end portion in the width direction of the cover plate 31. When the flange 17 and the side end portion in the width direction of the cover plate 31 overlap each other, the through hole is formed. Match. Here, for example, by passing a bolt and screwing a nut, the overlapping flange 17 and the side end portion in the width direction of the lid plate 31 can be fastened, and the lid body 30 can be attached to the groove body 10. . The flange 17 is also disposed at the lower end edge of the side wall portion 12.

  The groove main body 10 does not correspond to the bottom part 11 of the groove main body 10 according to the first embodiment, and includes only a pair of left and right side wall parts 12. As described above, the side wall portion 12 includes the flange 17 at each of the upper end and the lower end. In addition, reinforcing ribs 18 are arranged at appropriate positions in the longitudinal direction of the side wall portion 12 in order to give the side wall portion 12 strength and, in turn, to give the entire groove body 10 strength. The reinforcing rib 18 is joined to the side wall portion 12 and the pair of upper and lower flanges 17 by welding, for example, so that the reinforcing rib 18 is joined across the side wall portion 12 and the pair of upper and lower flanges 17 and is not deformed by the load received from the lid 30. It has rigidity.

  In this embodiment, the flange 50 for connecting the adjacent segments 2 includes the reinforcing ribs 18 at both ends in the longitudinal direction of the groove body 10 and the reinforcing ribs 42 at both ends in the longitudinal direction of the lid 30. Plays.

  The segment 2 includes a connecting plate 54 at one end in the longitudinal direction of the segment 2.

That is, the connecting plate 54 has a function of connecting the pair of left and right side wall portions 12 of the groove main body 10 and connecting end portions in the longitudinal direction of the groove main body 10 of the adjacent segments 2. Specifically, the connecting plate 54 has through holes 55 at four corners, and each through hole 55 is a through hole (illustrated) formed at the end of the flange 17 on the lower side of the side wall portion 12. Do not match).

  When installing the side groove 1, first, the groove body 10 is disposed on the foundation B through the connecting plate 54 in a state where the lid body 30 is not attached. At this time, it is confirmed whether or not the arc of the side groove 1 is appropriate as a whole. If there is no problem, the foundation bolt B is passed with the anchor bolt passing through the through hole of the lower flange 17 and the through hole 55 of the connecting plate 54. The side groove 1 is fixed to the foundation B. In addition, as shown in FIG. 9A, a through hole 19 is formed at an appropriate place in addition to the through hole at the end of the lower flange 17, and this through hole 19 is used as necessary. Then, the number of anchor bolts driven into the foundation B can be increased, and the fixing degree can be increased.

  When the plurality of groove main bodies 10 are connected in an arc shape (strictly polygonal side shape) and fixed to the foundation B, concrete is placed in the groove main body 10 as shown by dots in FIG. As described above, the concrete constitutes the bottom surface of the water channel and forms a gradient necessary for the water channel.
