  By the way, in the partition material a of the conventional configuration, as shown in FIG. 11 (A), when the partition plate portion c is curved toward the side where the mounting plate portion b is present, or as shown in FIG. 11 (B). In addition, in any case where the partition plate portion c is bent to the side where there is no mounting plate portion b, a plurality of narrow connection edges e provided on the outer side of each notch hole d are used at the construction site. In addition, there is a problem in that work efficiency is poor because it is necessary to sequentially cut using a tool such as a gold saw or a bolt clipper.

  The present invention was made to solve such problems, and provides a partition material for soil that does not require cutting work when the partition plate portion is curved toward the side where the mounting plate portion is located. It is the purpose.

  The present invention includes a horizontal mounting plate portion extending in the longitudinal direction, a partition plate portion raised upward from one side edge of the mounting plate portion, and an upward bend on the other side edge of the mounting plate portion. A long metal thin plate having a substantially L-shaped cross section provided with a narrow rising edge, and a mounting plate portion having a lateral width extending between the partition plate portion and the narrow rising edge; A soil partitioning material, wherein hole-shaped cutout holes having a straight side that coincides with the lower end position of the width-shaped rising edge are formed at predetermined intervals along the longitudinal direction of the mounting plate portion. is there.

  In such a configuration, the mounting plate portion may be formed with a plurality of through holes for inserting the fixing rod along the longitudinal direction thereof. Here, when fixing the partition material for soil on the artificial ground to be the edge of the planting region, the tapping screws as fixing rods are inserted through the plurality of through holes formed in the attachment plate portion respectively from above, Fixing means for fixing the tapping screw by screwing the tip of the tapping screw to a plug embedded in the artificial ground, and fixing means for fixing the lower surface of the mounting plate part to the waterproof layer on the artificial ground using double-sided tape is applied. In the case where the double-sided tape is used as described above, the through hole of the mounting plate portion is not necessary. Moreover, when fixing the partition material for soil on the ground used as the edge of a pavement area | region, the fixing means which drives and fixes the anchor penetrated to each through-hole of an attachment board part to a ground is applied.

  In this partition material for soil, a configuration is proposed in which a water drain hole continuing to the notch hole is formed in the lower part of the partition plate portion.

  Moreover, the structure by which the reinforcement edge formed by folding the upper end of a partition plate part is formed is proposed.

  As described above, the present invention includes a horizontal mounting plate portion extending in the longitudinal direction, a partition plate portion raised upward from one side edge of the mounting plate portion, and the other side of the mounting plate portion. A long thin metal sheet having a substantially L-shaped cross section having a narrow rising edge bent upward at the edge, and a lateral width extending between the partition plate part and the narrow rising edge on the mounting plate part. And a partition material for soil in which hole-shaped cutout holes having a straight side that coincides with the lower end position of the narrow rising edge are formed at predetermined intervals along the longitudinal direction of the mounting plate portion. Therefore, when bending the partition plate part to the side where the mounting plate part is located, pre-bending that presses the outer surface part of the narrow rising edge located above each notch hole with a finger and slightly pushes it into the notch hole After applying, hold the partition plate with both hands and bend it to the side with the mounting plate. Pressurizing and edge rising narrow shape bent into a substantially V-shaped in each notch hole, it is possible to the partition plate portion is easily bent into a desired curved shape. Here, since the straight side of the notch hole is coincident with the lower end position of the narrow rising edge, the narrow rising edge is not affected by the resistance of the mounting plate portion when pressure is applied by human power. It can be bent in a substantially V shape in the thickness direction, and the partition plate portion is made uniform without causing local bending in the partition plate portion due to the substantially V-shaped bending deformation in the thickness direction of the narrow rising edge. Can be curved and molded. Moreover, since the partition material for soil is made of metal, in addition to the shape holding action by the plastic deformation of the partition plate part itself, the partition by the shape holding action by the plastic deformation of the narrow rising edge bent in a substantially V shape. The curved state of the plate portion is more firmly maintained. Since the partition plate portion can be bent to the side where the mounting plate portion is present only by a pressure operation by human power in this way, a cutting operation is unnecessary, and the work efficiency is improved.

  In the partition material for soil, in the configuration in which a drain hole continuing to the notch hole is formed in the lower part of the partition plate part, the punching process by a die of the notch hole formed in the mounting plate part Sometimes, drainage holes can be formed at the same time with the same mold, so that workability is good, and when the planting area is partitioned by a partition material for soil, it is impregnated in mat-like artificial soil laid in the planting area. Surplus water such as rainwater can be drained naturally through the drain holes.

  Further, in the configuration in which the reinforcing edge formed by folding the upper end of the partition plate portion is formed, the strength of the partition plate portion can be increased by the reinforcing edge, and at the time of bending operation of the partition plate portion, Thus, the entire force can be uniformly bent without the partition plate portion being locally bent. Moreover, safety | security improves and the malfunction which cuts a hand at the upper end of a partition plate part can be prevented.

  As shown in FIGS. 2 and 3, the soil partition 1 according to the present invention rises upward from a horizontal mounting plate portion 2 extending in the longitudinal direction and one side edge of the mounting plate portion 2. In the attachment plate portion 2 of the long thin metal plate 5 having a substantially L-shaped cross section comprising a partition plate portion 3 and a narrow rising edge 4 bent upward on the other side edge of the attachment plate portion 2. A hole-shaped cutout hole 6 having a lateral width extending between the partition plate portion 3 and the narrow rising edge 4 and having a straight side corresponding to the lower end position of the narrow rising edge 4 is attached. It is characterized by being formed at predetermined intervals along the longitudinal direction of the plate part 2.

Below, one specific Example of the said partition material 1 for soil is demonstrated based on FIGS.
The long metal thin plate 5 is formed by bending a long strip-shaped metal thin plate into a substantially L-shaped cross section. As the material of the long metal thin plate 5, a steel plate such as stainless steel or steel having a length of about 2025 mm, a width of about 270 mm, and a thickness of about 1.2 mm can be preferably used. The long metal thin plate 5 includes a horizontal attachment plate portion 2 extending in the longitudinal direction, a partition plate portion 3 rising upward from one side edge of the attachment plate portion 2, and the attachment plate portion 2. A narrow rising edge 4 bent upward is provided on the other side edge, and a plurality of cutout holes 6 are formed in the mounting plate portion 2 at predetermined intervals along the longitudinal direction.

  Each notch hole 6 is formed in a rectangular shape, and is arranged so that one side of the straight line coincides with the lower end position of the narrow rising edge 4. Further, the other straight side opposite to the one side is disposed at a position slightly upward from the lower end of the partition plate portion 3, and the opening at the lower portion of the partition plate portion 3 generated thereby is formed in the notch hole 6. The water drain hole 7 (see FIG. 3) is continuous with the above. Further, the mounting plate 2 is formed with through holes 8 that are positioned between the notch holes 6 and through which a fixing rod 9 described later is inserted. Further, the partition plate portion 3 is formed with a reinforcing edge 10 (see FIG. 5) formed by folding back the upper end by hemming bending. The reinforcing edge 10 can improve the strength of the partition plate portion 3 and further enhance its robustness, improve safety, and prevent a problem such as cutting the hand at the upper end of the partition plate portion 3. I am doing so.

  In order to manufacture the partition material 1 for soil having such a structure, as shown in FIG. 4, in a predetermined region near the one side edge that becomes the attachment plate portion 2 of the strip-like thin metal plate 14 as a material. A plurality of notch holes 6 and through-holes 8 are formed by punching with a pressing device, and then the end of the other side edge of the thin metal plate 14 is folded back by a virtual folding line 15 by a hemming bending process with a pressing device. 10 is formed. Thereafter, one side edge of the thin metal plate 14 is bent at a substantially right angle by an L bending process by a press device at a virtual folding line 16 at a position coinciding with one side outside the notch hole 6 and the narrow rising edge 4 is formed. Next, a substantially intermediate portion in the width direction of the thin metal plate 14 is a virtual folding line 17 at a position slightly outside the inner side of the notch hole 6, and a narrow-width rising edge is formed by L-bending by a pressing device. 4, the partition plate portion 3 is formed by being bent at a substantially right angle in the same direction. Thereby, the said partition material 1 for soil can be manufactured easily.

  5 and 6 show a construction state of the planting S on the artificial ground G such as a rooftop using the soil partitioning material 1 having such a configuration. In order to perform such construction, first, the partition material for soil 1 is fixed through fixing means along the edge of the planting region. As shown in FIG. 5, the fixing means includes a fixing rod 9 made of a tapping screw inserted through the through hole 8 of the mounting plate portion 2 and a plug 12 embedded in the artificial ground G. The artificial ground G is embedded at a predetermined interval that coincides with the through holes 8 of the mounting plate 2. Then, the attachment plate portion 2 is fixed to the artificial ground G by screwing and tightening the distal end side of the fixing rod 9 inserted through the through hole 8 of the attachment plate portion 2 to the plug 12. Here, the mounting plate part 2 is disposed so as to be located inside the planting region. In addition, as shown in FIG. 6, when the waterproof layer B is laid on the artificial ground G, the waterproof action is impaired when the waterproof layer B is perforated by the plug 12. A fixing means for applying the lower surface to the waterproof layer B on the artificial ground G by the double-sided tape 13 and fixing it is applied. Thereby, the partition plate part 3 of the partition material 1 for soil is erected along the edge of the planting region, and the edge of the planting region can be partitioned by the partition plate 3. And the edge part of this artificial soil M can be hold | maintained by the partition plate part 3 by laying the artificial soil M shape | molded in mat shape inside the partition material 1 for soil installed in this way. Further, the drain hole 7 (see FIG. 6) is formed in the lower part of the partition plate portion 3 so that excess water such as rain water impregnated in the artificial soil M by the drain hole 7 can be drained naturally. it can.

  In the construction as described above, when partitioning the edge of the planting area in a straight line, the soil partition 1 is used in a straight line. Moreover, when dividing the edge part of a planting area | region into a curve shape, the partition plate part 3 of the partition material 1 for soil is curved and used. In this bending operation, when the partition plate portion 3 is bent toward the side where the mounting plate portion 2 is present, the outer surface portion of the narrow rising edge 4 positioned on one side of each notch hole 6 is added with a finger. After preliminarily bending by pressing and slightly pushing into each notch hole 6, holding the partition plate portion 3 with both hands and pressurizing the mounting plate portion 2 toward the side, as shown in FIGS. 7 and 8 In addition, the narrow rising edge 4 is bent into a substantially V shape within each notch hole 6, whereby the partition plate portion 3 can be easily curved into a desired curved shape. Here, the notch hole 6 has a lateral width extending between the partition plate portion 3 and the narrow rising edge 4, and one straight side thereof coincides with the lower end position of the narrow rising edge 4. During pressurization by human power, the narrow rising edge 4 can be bent in a substantially V shape in the thickness direction without receiving the resistance of the mounting plate portion 2, and the narrow rising edge 4 in the thickness direction can be bent. Due to the substantially V-shaped bending deformation, the partition plate portion 3 can be uniformly bent without causing local bending in the partition plate portion 3. Moreover, since the partition material 1 for soil is metal, in addition to the shape maintenance effect | action by the plastic deformation of the partition part 3 itself, the shape maintenance effect | action by the plastic deformation of the narrow-width rising edge 4 bent in the substantially V shape. As a result, the curved state of the partition plate portion 3 is more firmly maintained. And since the partition plate part 3 can be curved to the side with the mounting plate part 2 only by the pressurizing operation by human power in this way, the cutting work is unnecessary, and the work efficiency is improved.

  When the partition plate portion 3 is curved to the side where the mounting plate portion 2 is not present, the mounting plate portion 2 is cut by cutting the narrow rising edge 4 located above each notch hole 6 with a tool. The bending operation of the partition plate part 3 to the side where there is no gap becomes possible. However, in the planting construction, the curved soil partition material 1 is used to partition the planting area into a circular shape, or the corner of the planting area is partitioned into an R shape. In this case, the partition plate portion 3 is curved to the side where the mounting plate portion 2 is used, so that the cutting operation of the narrow rising edge 4 as described above is hardly required.

  Moreover, although the example which formed the rectangular-shaped notch hole 6 in the attachment board part 2 was shown in the said Example, this notch hole 6 is provided with the horizontal width ranging between the partition plate part 3 and the narrow-shaped rising edge 4. FIG. And the hole shape should just be provided with the linear one side which corresponds to the lower end position of the narrow-width rising edge 4. 9 (A) and 9 (B) show other shapes of the notch hole 6, in FIG. 9 (A), the notch hole 6 is formed in a substantially triangular shape, and in FIG. 9 (B), the notch hole 6 is shown. Is formed in a substantially semi-elliptical shape. The notch hole 6 having such a shape is arranged with a horizontal width extending between the partition plate portion 3 and the narrow rising edge 4 so that one straight side thereof coincides with the lower end position of the narrow rising edge 4. Thus, the partition plate portion 3 can be easily curved to the side where the mounting plate portion 2 is located without cutting the narrow-width rising edge 4 and without receiving the resistance of the mounting plate portion 2.

  Moreover, although the said Example demonstrated the case where a planting area | region was partitioned off using the partition material 1 for soil, the partition material 1 for soil concerning this invention has the fixing rod which consists of an anchor penetrated by the through-hole 8. FIG. By being driven into the ground and fixed, it can also be used to partition the pavement area in pavement work such as roads, sidewalks, and parking lots.
