[Problems to be solved by the invention]
By the way, in the partition plate used in the conventional construction method as described above, first, a wooden pile is driven in, and then the partition plate is driven into the wooden pile with a nail, so that installation work is troublesome. However, it took time and effort, and there was a problem that work efficiency was poor. Moreover, since the partition plate is a wooden flat plate, there is a problem that it cannot be easily handled when the partition is not bent and the edge of the pavement region is curved.
[0004]
On the other hand, as an alternative to the conventional partition plate, an anchor insertion portion made of a metal pipe or the like is provided on a metal partition plate, and the anchor inserted through the anchor insertion portion is screwed into the anchor insertion portion from the side. Although what was locked by the set screw inserted is proposed by Japanese Utility Model Laid-Open No. 6-74609, etc., there is a problem that the structure is complicated and the cost is high.
[0005]
The object of the present invention is to provide a partition material for pavement that can solve the conventional problems.
[0006]
[Means for Solving the Problems]
The present invention has a cross-section L comprising a horizontal mounting plate portion extending in the longitudinal direction and a partition plate portion rising vertically from one end of the mounting plate portion and having a reinforcing edge formed by folding the upper end. A plurality of rectangular notches with a side aligned with the lower end position of the partition plate portion are formed at predetermined intervals along the longitudinal direction on the mounting plate portion of the long metal sheet having a shape, and the attachment The narrow connecting edge formed on the outer side of the notch hole in the plate portion is used as a cutting allowance to be cut as necessary to open the notch hole, and a through hole for anchor insertion is provided between the notch holes and at both ends.

[0013]
In order to manufacture the paving partition material 1 having such a configuration, first, a notch hole 5 and a through-hole 8 are formed by punching with a pressing device on one side edge that becomes the attachment plate portion 2 of a strip-shaped metal thin plate. Are formed at the same time, and then the end of the other side edge of the metal thin plate is folded back by hemming bending with a press device to form the reinforcing edge 10. Thereafter, at a middle portion in the width direction of the thin metal plate, a position that coincides with one side inside the notch hole 5 is bent at a substantially right angle by bending with a press device. Thereby, the partition material 1 for pavement can be manufactured easily.
[0014]
Next, the usage method and effect | action of the partition material 1 for pavements concerning this invention are demonstrated.
FIG. 4 shows a pavement construction state using the paving partition material 1 of the present invention. A crusher run 12 such as gravel or crushed stone is spread on the ground 11, and the cushion sand 13 is spread on the crusher run 12. A paving material 14 made of an interlocking block is laid, and the outer end of the paving material 14 is positioned by the paving partition material 1.
[0015]
In the case where such pavement is performed, when the edge of the pavement area is constructed in a straight line, first, the crusher run 12 is spread on the ground 11 to prepare the pavement area, and along the edge of the pavement area. Then, the linear pavement partition material 1 is placed as it is. Next, an anchor 9 formed in a substantially nail shape is inserted into the through hole 8 of the mounting plate portion 2, and the anchor 9 is driven into the ground 11 from above the crusher run 12 to fix the paving partition material 1. Thereby, the partition plate part 3 stands up along the edge part of a pavement area | region, and the edge part of a pavement area | region can be partitioned linearly by this partition plate part 3. FIG. Here, when the edge part of a pavement area | region is long and it is necessary to connect and use the several partition material 1 for pavements, as shown in FIG. 1 end portions are abutted, and both end portions thus abutted are connected by a joint metal fitting 15. As shown in FIG. 6, the joint fitting 15 is formed in an L-shaped cross section, and has insertion holes 16 and 16 formed on both sides of the horizontal plate portion 15 '. The insertion holes 16 and 16 are abutted against each other. Further, the pavement partitioning materials 1 and 1 are provided at positions corresponding to the through holes 8 and 8 at the end portions. The joint metal fitting 15 is mounted on both ends of the paved partitioning materials 1 and 1 so as to straddle, and the anchor 9 is inserted into each of the insertion holes 16 and the through holes 8 that coincide in the vertical direction. 11 can be easily connected to each other.
[0016]
Then, cushion sand 13 is laid inside the paving partition 1 installed as described above. At this time, the cushion sand 13 is dammed up by the partition plate portion 3 erected along the edge of the pavement region, and the outflow to the outside is prevented. Thereafter, a block as a paving material 14 is laid on the cushion sand 13. At this time, by bringing the end of the block into contact with the partition plate portion 3, the block can be easily positioned, and each block can be laid in an orderly manner along the edge of the pavement area. Then, the pavement surface is finished by rolling the upper surface of the pavement material 14 composed of the blocks laid last. At this time, the pavement partition material 1 is made of metal and has excellent robustness, so that it can withstand even when pressure from the side by rolling is applied to the partition plate portion 3, and the pavement material The 14 ends can be held firmly.
[0017]
On the other hand, when the edge of the pavement region is constructed in a curved shape, as shown in FIGS. 7A and 7B, by cutting the narrow connection edge 6 as the cutting margin 7 provided in the mounting plate 2. Moreover, the partition plate part 2 can be freely curved. Here, since the partition material for pavement 1 is made of metal, the curved state is maintained by the plastic deformation, and can easily match the curved shape of the edge of the pavement region. Further, since one side of the cutout hole 5 is provided so as to coincide with the lower end position of the partition plate portion 3, the partition plate portion is not subjected to the resistance of the mounting plate portion 2 when the narrow connection edge 6 is cut. 3 can be easily bent in the thickness direction. Further, since the reinforcing edge 10 is formed on the upper end of the partition plate portion 3, the applied force is dispersed by the reinforcing edge 10 during the bending operation of the partition plate portion 3, and the bending of the partition plate portion 3 is locally bent. The whole can be curved in a straight line without generating.
[0018]
Then, the partition material 1 for pavement curved in advance in this way is fixed to the ground 11 by the anchor 9 in the same manner as described above, so that the partition plate portion 3 stands up along the edge of the pavement region, and the partition The edge of the pavement area can be partitioned in a curved shape by the plate part 3. And when rolling the upper surface of the pavement material 14 filled inside the partition plate part 3, the end of the pavement material 14 can be firmly held without causing a shift, and the edge of the pavement material 14 The part can be finished in a desired curved shape.
[0019]
Further, as shown in FIGS. 8A and 8B, only one portion of the narrow connecting edge 6 is cut and the partition plate portion 3 is bent at a substantially right angle, so that the corner portion of the pavement region can be constructed. It can be easily handled.
[0020]
By the way, although it is also considered that the paving partition material 1 according to the present invention is formed of a synthetic resin, the synthetic resin is disadvantageous in that it is vulnerable to heat. That is, when asphalt pavement is performed, the edge of the pavement area is partitioned by the synthetic resin paving partition material 1, and when the hot asphalt as the paving material 14 is filled inside the partition plate portion 3, The partition part 3 will deform | transform and the holding | maintenance effect | action of the pavement 14 will not be obtained. In order to eliminate such a problem, the paving partition material 1 according to the present invention is formed using a thin metal plate and has excellent heat resistance.
[0021]
In addition, although the example which formed the rectangular-shaped notch hole 5 in the attachment board part 2 was shown in the said Example, this notch hole 5 should just be a hole shape provided with the linear one side. 9A and 9B show other shapes of the cutout holes 5, in which the cutout holes 5 are formed in a triangular shape, and in FIG. 9B, the cutout holes 5 are formed in a semi-elliptical shape. . The cutout hole 5 having such a shape is arranged with its straight side aligned with the lower end position of the partition plate portion 3, so that the narrow connection edge 6 is cut and the attachment plate portion 2 is cut. The partition plate portion 3 can be easily bent in the thickness direction without receiving resistance.
[0022]
Further, as shown in FIG. 10, a V-shaped notch groove 17 may be formed on the outer edge of the narrow connecting edge 6. As a result, when cutting the narrow connecting edge 6, the gold saw engages with the notch groove 17, and the cutting operation can be easily performed without shifting the cutting position. The cutout groove 17 may be any shape that can be positioned by engaging a gold saw, and is not limited to the V shape as shown.
[0023]
