  Embodiments of the present invention will be described below in detail with reference to the drawings. In addition, what has the same function attaches | subjects the same code | symbol, and the repeated description may be abbreviate | omitted.

  First, attachment of the block weed protection member according to the present invention to a concrete block installed at an end of the road 100 or the like will be described. FIG. 1 is a perspective sectional view of a gutter block 300 to which a weedproof member 400 is attached, FIG. 2 is a front sectional view thereof, and FIG. 3 is a side view thereof.

  The road 100 is a passage maintained for people and vehicles to travel. The surface of the road 100 is covered with a pavement material using asphalt 200 or the like so that it can easily pass over the ground 500. Concrete blocks such as drainage gutter blocks 300 are installed at the ends of the road 100 and the like. Concrete is a stone made by solidifying sand, gravel, water, etc. with cement.

  The side groove block 300 is a concrete block having a vacant upper surface, and is installed to allow unnecessary water to flow. The bottom surface of the side groove block 300 may have a curved U shape or a flat concave shape. The upper surface of the side groove block 300 is usually closed by fitting the lid plate 310, but it may remain empty. It should be noted that a step for hooking the inner side of the gutter block 300 may be provided so that the cover plate 310 can be removed.

  When removing the lid plate 310, a finger or a lifting tool is inserted into the hole 311 formed in the end of the lid plate 310 and the like, and the lid plate 310 is lifted while being hung on the back side of the lid plate 310. Although the same concrete block as the gutter block 300 is mainly used for the cover plate 310, a grating 320 which is lightened by assembling metal in a lattice shape so as to facilitate drainage may be used. When the height of the upper surface of the cover plate 310 or the grating 320 and the height of the upper surface of the asphalt 200 are matched, it does not interfere with walking or running.

  The side groove block 300 is buried in a groove dug in the ground 500 at the same depth as the side groove block 300. The gutter block 300 creates a space in the ground 510 through which liquid such as water flows. Instead of the side groove block 300, a culvert block having no open upper surface may be used. Since the gutter block 300 is often installed at the end of the road 100, the gutter block 300 and the asphalt 200 are adjacent to each other.

  In the ground 500, weeds 520 grow, but when a gap or the like is generated between the gutter block 300 and the asphalt 200 and there is a gap 530, the weeds 520 extending from the ground become gutter blocks. It may come out between 300 and asphalt 200. If the weeds 520 grow, it looks bad, and the weeds 520 may hide the gutter block 300 and hide it.

  Therefore, as shown in FIG. 1, the weedproof member 400 is attached to the gutter block 300. The weedproof member 400 is a member for preventing the gap 530 by preventing the gap between the asphalt 200 and the like paving the road 100 and the concrete block such as the gutter block 300. The gap 530 is blocked and the weed 520 is prevented from extending from there. That is, by using the weedproof member 400, the portion that becomes the gap 530 is prevented from being directly connected to the ground 510.

  As shown in FIG. 2, the grass protection member 400 itself is fixed to the side groove block 300 with a fastener 600 or the like, but the side groove block 300 and the asphalt 200 are connected by hooking a part of the grass protection member 400 to the asphalt 200. For example, a part of the weed prevention member 400 is inserted into the back surface of the asphalt 200 like a protrusion 410 to maintain the state where it is brought closer to the side groove block 300 side.

  For example, even if seeds of weed 520 exist in the ground 510, the weed 520 does not reach the gap 530 between the gutter block 300 and the asphalt 200 beyond the protrusion 410 of the weed prevention member 400. Don't come out. Even if the seed of weed 520 enters the gap 530, the root of the weed 520 does not reach the ground 510, so that the weed 520 is withered.

  When the grass protection member 400 is attached to the non-installed side groove block 300, the side groove block 300 with the grass protection member 400 is disposed at a predetermined position on the road 100, and then the road 100 is paved with the asphalt 200. It ’s fine. When the grass protection member 400 is attached to the existing gutter block 300, the asphalt 200 may be partially removed, the grass protection member 400 may be attached to the gutter block 300, and the removed portion may be paved again with the asphalt 200.

  The weedproof member 400 is fixed to the contact surface 330 or the processing surface 340 of the gutter block 300. Of the left and right side surfaces of the gutter block 300, only the side adjacent to the asphalt 200 may be used. The contact surface 330 is the upper part of the side surface of the gutter block 300, but contacts the asphalt 200 at a predetermined depth from the upper end, so that the predetermined depth necessary for fixing the grass protection member 400 from a position shallower than the depth of the asphalt 200 is provided. Provided within the range.

  The shape of the weedproof member 400 may be formed in accordance with the shape of the portion that becomes the contact surface 330 of the side groove block 300. Further, the processing surface 340 may be formed by cutting a portion that becomes the contact surface 330 of the side groove block 300 in accordance with the shape of the grass prevention member 400. The fastener 600 only needs to be able to fix the weedproof member 400 to the side groove block 300, and may be screwed into the side groove block 300 through the weedproof member 400.

  As shown in FIG. 3, the weedproof member 400 is screwed together with a fastener 600 such as a screw at several places including both ends, one piece corresponding to the length of one side groove block 300. Alternatively, two grass protection members 400 having a half length of the side groove block 300 may be arranged and screwed together with an arbitrary number of fasteners 600. Similarly, a plurality of grass protection members 400 having a predetermined length may be arranged and screwed at arbitrary positions. Moreover, you may arrange | position and fix intermittently, without connecting the some grass-proof member 400. FIG.

  Next, the structure of the grass protection member for blocks according to the present invention will be described. FIG. 4 is a perspective view of the weedproof member 400, and FIG. 5 is a perspective sectional view of the side groove block 300 processed for attaching the weedproof member 400. FIG. The weedproof member 400 may depend on the shape of the side groove block 300, but if it has a function of connecting the side groove block 300 and the asphalt 200, it is not necessary to have a regular shape.

  As shown in FIG. 4, as an example of the structure of the weedproof member 400, the projection 410, the abutting portion 420, the vertical portion 430, and a plurality of through holes 440 are provided. The weedproof member 400 is retrofitted to the side groove block 300, and may be formed of the same concrete as the side groove block 300, or may be formed using an easily processable material such as metal or resin. In the case of a resin, it is preferable to use a hard material that does not corrode.

  The contact portion 420 is a portion that abuts against the contact surface 330 of the gutter block 300. In order to pass the fastener 600 to the side groove block 300, for example, one through hole 440 is made closer to the left end and one through hole 440 is made closer to the right end. The side of the contact portion 420 that contacts the contact surface 330 may be flat or processed according to the contact surface 330. The abutting portion 420 and the contact surface 330 or the processed surface 340 are formed in a shape in which unevenness and the like match so that no gap is formed.

  When processing the side groove block 300, as shown in FIG. 5, the side surface of the side groove block 300 is cut to form the contact surface 330. For example, when the contact portion 420 is a flat surface, if the side surface of the side groove block 300 has many irregularities, the contact surface 330 is formed by cutting the flat surface to be flat. Further, a screw hole 350 for screwing the fastener 600 into the contact surface 330 is made in alignment with the through hole 440 made in the contact portion 420.

  As shown in FIG. 4, the erected portion 430 is a portion that is bent at a right angle and continuously provided from the contact portion 420 to the outside, that is, in a direction away from the side groove block 300. The vertical portion 430 is interposed in order to separate the protrusion 410 from the side surface of the side groove block 300 by a predetermined length. Note that the vertical portion 430 may be provided continuously from a place other than the upper end of the contact portion 420. Since it is perpendicular to the contact part 420, when the contact part 420 is vertically oriented along the side groove block 300, the vertical part 430 is horizontally oriented.

  The protrusion 410 is a portion that allows the side groove block 300 and the asphalt 200 to bite into the asphalt 200 so as not to be separated even when subjected to driving or other vibrations. When the protrusion 410 exists on the lower side of the asphalt 200, the protrusion 410 protrudes upward and bites into the lower surface of the asphalt 200. Further, the top surface of the protrusion 410 may be scraped downward and the tip may be sharpened to make it easy to bite.

  Thus, by installing the grass protection member 400 to a concrete block such as a newly installed or existing gutter block 300 or the like, the gap between the asphalt 200 and the concrete block on the road 100 is prevented, and further, the gap 530 is eliminated. The growth of weeds 520 extending therefrom can be suppressed. Since it can be easily attached to an existing concrete block, a great saving can be achieved in terms of work and cost.

  Next, attaching the grass protection member for a block according to the present invention to a concrete block installed between the roadway and the sidewalk of the road 100 will be described. 6 is a front sectional view of the boundary block 301 to which the weedproof member 400 is attached, and FIG. 7 is a front sectional view of the curb block 302 to which the weedproof member 400 is attached.

  In the road 100, concrete blocks such as a boundary block 301 are installed at boundaries such as between the roadway and the sidewalk, and between the up lane and the down lane so as not to get over the lane. It is assumed that asphalt 200 or the like is paved on the surface of the road 100 adjacent to the boundary block 301. A grass protection member 400 is attached between the boundary block 301 and the asphalt 200.

  As shown in FIG. 6, the boundary block 301 is a concrete block mainly having a portion protruding upward. The protruding portion that is the upper part of the boundary block 301 may have a substantially trapezoidal shape or other shapes. The lower part of the boundary block 301 is buried in the ground 510, and both or one of the side surfaces thereof is a contact surface 331 adjacent to the asphalt 200. Note that the contact surface 331 may be cut into the processed surface 341 in accordance with the shape of the grass prevention member 400.

  The grass protection member 400 is fixed to the contact surface 331 or the processing surface 341 of the boundary block 301 with the fastener 600, and paved with the asphalt 200 to a position adjacent to the lower portion of the boundary block 301. Since the projection 410 of the weed prevention member 400 is hung on the asphalt 200, the boundary block 301 and the asphalt 200 are in a state in which the gap 530 is hardly generated even by vibration or the like. Further, the growth of the weeds 520 is inhibited by the weed control member 400.

  The same applies to the curb block 302 as shown in FIG. The curb block 302 is a concrete block installed on the shoulder of the road 100. The curb block 302 is installed in order to prevent the end of the asphalt 200 from being damaged and to maintain the paving by the asphalt 200. The grass prevention member 400 is attached between the curb block 302 and the asphalt 200.

  Since the lower portion of the curb block 302 is embedded in the ground 510, the upper side surface becomes the adjacent surface 332, and the contact surface 332 may be cut into the processed surface 342 in accordance with the shape of the grass protection member 400. The grass protection member 400 is attached to the contact surface 332 or the processing surface 342 with the clasp 600 and paved with the asphalt 200 to a position adjacent to the curb block 302. At that time, the protrusion 410 of the grass prevention member 400 is locked to the asphalt 200.

  As described above, even in the case of concrete blocks such as the boundary block 301 and the curb block 302, weeds extending from the asphalt 200 and the concrete block on the road 100 are prevented by further eliminating the gap 530. The growth of 520 can be suppressed. Since it can be easily attached to an existing concrete block, a great saving can be achieved in terms of work and cost.

  Next, the shape of the grass protection member for blocks according to the present invention will be described. FIG. 8A is a front view of a right-angle crank-shaped weedproof member 401, and FIG. 8B is a front view of a U-shaped weedproof member 402.

  As shown in FIG. 8A, the grass prevention member 401 includes an abutting portion 421, an upright portion 431 provided in a perpendicular direction from the upper end of the abutting portion 421, and an abutting portion of the upright portion 431. You may make it the shape which has the processus | protrusion 411 connected so that it may extend long upwards from the edge on the opposite side to the part 421. FIG. The protrusion 411 of the weed prevention member 401 is not sharpened at the tip, but can be penetrated deeply when the asphalt 200 layer is thick. Further, when the attachment position of the grass protection member 401 is low and the distance from the grass protection member 401 to the asphalt 200 is separated, the protrusion 411 can reach the asphalt 200.

  Further, as shown in FIG. 8B, the weed prevention member 402 includes a contact portion 422, a vertical portion 432 provided in a direction perpendicular to the lower end of the contact portion 422, and a vertical portion 432. You may make it the shape which has the protrusion 412 provided in a row so that it might extend long upwards from the edge on the opposite side to the contact part 421. FIG. This is a suitable shape when the attachment position of the weedproof member 402 is high and the asphalt 200 layer is thick.

  In this way, by changing the shape of the weedproof members 400, 401, and 402 according to the installation status of a new or existing concrete block, it becomes easy to attach to the concrete block, and the work and cost are greatly saved. can do. By retrofitting the weedproof members 400, 401, and 402, the gap between the asphalt of the road and the concrete block is eliminated, so that the growth of weeds extending therefrom can be suppressed.

  As mentioned above, although the Example of this invention was described, it is not limited to these.
