By the way, in the partition plate used in the conventional construction method as described above, first, a wooden pile is driven, and then the partition plate is nailed to the wooden pile. Therefore, the installation work is troublesome and time-consuming, and there is a problem that the work efficiency is poor. Further, since the partition plate is a wooden flat plate, there is a problem that it cannot be easily dealt with when the edge portion of the pavement region is curved without being bent.

On the other hand, as an alternative to such a partition plate of the conventional construction method, an anchor insertion part made of a metal pipe or the like is provided on a metal partition plate, and the anchor inserted through the anchor insertion part is anchored from the side. A device that is locked by a setscrew that is screwed into the insertion portion is proposed by Japanese Utility Model Laid-Open No. 6-74609, but the structure is complicated, the manufacturing is troublesome, and the assembly is troublesome. There were difficulties. In particular, since the partition plate has a structure in which it is vertically supported by an anchor that is driven into the ground, there is a problem that the partition position shifts depending on how the anchor is driven, and the partition plate easily tilts back and forth.

It is an object of the present invention to provide a partitioning material for pavement which can solve the above conventional problems.

Next, the method of use and the operation of the partitioning material 1 for pavement according to the present invention will be described. Prior to the construction, first, the plurality of support base pieces 3 and the partition plate main body 2 are assembled. This is performed by tapping the lower edge of the partition plate main body 2 into the fitting groove portion 4 of each support base piece 3 from above to fit it. In this manner, by fitting the lower edge of the partition plate body 2 into the fitting groove portion 4 of each support base piece 3, the partition plate body 2 is vertically formed by each support base piece 3 as shown in FIG. Can be held. Further, the retaining projections 5 and 5 of the partition plate body 2 and the engaging protrusions 8 and 8 of the fitting groove portion 4 mesh with each other to obtain a retaining function of the partition plate body 2, and the meshed state thereof. Therefore, each support base piece 3 can be slid along the longitudinal direction of the partition plate body 2. Thereby, the mounting position of each support base piece 3 can be adjusted, and each support base piece 3 can be easily assembled along the longitudinal direction of the partition plate body 2 at a predetermined interval (about 220 mm interval).

FIG. 4 shows an example of pavement construction using the pavement partitioning material 1 assembled as described above, in which a crusher run 12 of gravel, crushed stone, etc. is spread over the ground 11.
A paving material 13 made of asphalt is laid on the crusher run 12, and an outer end of the paving material 13 is positioned by the paving partition material 1.

In the case of pavement as described above, when the edge portion of the pavement area is to be linearly constructed, first, the ground 1
A crusher run 12 is laid on the pavement 1 to prepare a pavement area, and a linear paving partition material 1 is placed along the edge of the pavement area as it is. Next, the through hole 10 of the support base piece 3.
An anchor 9 formed in a substantially nail shape is inserted into the above, and the anchor 9 is driven into the ground 11 from above the crusher run 12 to fix the paving partition member 1. As a result, the partition plate body 2 is erected upright along the edge of the pavement area, and the partition plate body 2
The edge of the pavement area can be partitioned in a straight line. Here, the pavement partitioning material 1 can drive the anchor 9 in a state in which each support base piece 3 is placed on the crusher run 12 which is an installation surface, so that the partitioning plate body 2 does not shift from the partitioning position. Does not tilt back and forth.

Further, when the edge of the pavement area is long and it is necessary to connect and use a plurality of pavement partition materials 1,
As shown in FIG. 5, the ends of both pavement partitioning members 1 and 1 arranged in series are butted against each other with a slight thermal expansion clearance s, and the both ends of the butted parts are joined together.
Connect by 4. As shown in FIG. 6, the joint fitting 14 is formed in a substantially L-shaped cross section, and its horizontal plate portion 15 is formed.

The joint metal fitting 14 is mounted by straddling both ends of the butted pavement partition members 1 and 1, and the anchors 9 are inserted into the through holes 16 and the through holes 10 which are aligned in the vertical direction. By driving into 11, it is possible to easily connect the partitioning members 1 and 1 for both paving.

Then, the asphalt as the paving material 13 is filled inside the paving partitioning material 1 installed as described above. At this time, asphalt is blocked by the partition plate main body 2 that is erected along the edge of the pavement area, and the outflow to the outside is prevented. After that, the upper surface of the paving material 13 made of asphalt is rolled by a roller car to finish the paving surface. At this time, since the paving partition member 1 is made of an aluminum mold and has excellent strength, the partition plate body 2 does not buckle when the roller car rides on the paving partition member 1, and Since the partition plate main body 2 is formed with the ribs 6 along the longitudinal direction, even if a pressing force from the lateral side due to the rolling pressure is applied to the partition plate main body 2, the partition plate main body 2 withstands this and the partition plate main body 2 can On the other hand, the end portion of the pavement material 13 can be firmly held and can be finished in a straight line without being inadvertently curved and deformed.

On the other hand, when the edge of the pavement area is to be curved, the partition plate body 2 is curved in accordance with the curved shape of the edge of the pavement area. Here, since the partition plate body 2 is made of an aluminum mold material, as shown in FIG. 7, the partition plate body 2 can be freely curved, and its curved state is retained by its plastic deformation, and the curved shape of the edge of the pavement area is maintained. Can be easily matched to. Further, since the rib 6 is formed on the partition plate body 2, the applied force is dispersed by the rib 6 when the partition plate body 2 is bent, and the partition plate body 2 is locally bent. Without it, the whole can be curved uniformly.

The pavement partitioning material 1 thus pre-curved in this manner is ground by the anchor 9 in the same manner as described above.

Then, by filling the inside of the partition plate body 2 with the paving material 13 and rolling the upper surface thereof with a roller wheel, the edge portion of the paving material 13 can be finished into a desired curved shape.

Although not shown, by bending one part of the partition plate body 2 at a substantially right angle, it is possible to easily cope with the construction of the corner portion of the pavement area.

In the above-mentioned construction example, the construction of the pavement material 13 made of asphalt was explained. However, when asphalt pavement is carried out, the high temperature of the asphalt (about 180
It is desirable to use an aluminum mold member for each supporting base piece 3 so as to withstand the temperature (° C.). On the other hand, when a block is laid as the pavement material 13 in the pavement area partitioned by the partition plate body 2, heat resistance is not required, and thus the support base piece 3 made of a hard synthetic resin can be used. .

Further, in the above embodiment, the through hole 10 for inserting the anchor is formed in the flat plate piece portion 7 of the support base piece 3 at the time of manufacturing, but this through hole 10 is formed at the construction site. You can also By preliminarily forming the through holes 10 as in the embodiment, it is possible to save time and labor for successively forming the through holes 10 at the construction site, and improve work efficiency during construction.
