[0010]

Embodiments of the present invention will be described below with reference to the drawings. In the method for positioning and fixing a civil engineering frame pillar according to the present invention, for example, when paving a roadway, a roadbed material such as crushed stone, crushed stone or gravel is poured by digging the ground of the roadway portion, and for example, a roadbed 10 is formed as shown in FIG. I do.

Then, a plurality of frame pillars 11 are mounted on the roadbed 10.
Are arranged continuously by connecting the ends in the longitudinal direction with a slight gap s provided therebetween, and a pavement point b is defined between the concrete groove 13 and the sidewalk 12.

After that, as shown in FIGS. 7A and 7B, the positioning metal fittings 14 are placed over the ends of two adjacent civil engineering framework pillars 11 and extended between the ends. As shown in FIG. 6, the positioning metal fitting 14 is made of an iron plate having a thickness of, for example, about 5 mm, and has a slightly elongated flat plate-like top part 14a, a fixed nail insertion hole 14b formed at the center thereof, and a downward facing from both sides of the top part 14a. It is formed by providing a bent side edge portion 14c. Then, (A) and (B) of FIG.
As shown in the figure, the fixed nail insertion hole 14b is located on the gap s, and both ends of the top 14a are placed on the ends of the frame 11 respectively,
The ends of the frame 11 are sandwiched between the side edges 14c.

Then, as shown in FIGS. 1A and 1B, the fixing nail 15 is inserted from above into the fixing nail insertion hole 14b, passes through the gap s, and the tip is driven into the roadbed 10 to fix the same. The positioning fitting 14 is fixed with the nail 15. And
As a result, the top 14a of the positioning fitting 14 is pressed down from above, and the side edge 14c regulates the lateral displacement.
1 is positioned and fixed. As the fixed nail 15, for example, a nail for concrete driving is used.

Thereafter, the asphalt is poured into the pavement area B, and the pavement work is completed by compacting the asphalt with a road roller or a tire roller. After completion of the work, the positioning metal fitting 14 is lifted by inserting a tool into the gap s, and
5, the positioning post 14 and the fixing nail 15 are removed, and then the frame 11 is removed.

When it is desired to increase the thickness of the pavement, a plurality of frame pillars 11 are continuously arranged again on the roadbed on which the first layer is paved, and the positioning brackets 14 are similarly stretched between the ends of the frame pillars 11 and fixed. It is fixed with nails 15 and the second layer is paved in the same manner. If necessary, this can be repeated to obtain a pavement having a desired thickness.

When two adjacent frame pillars 11 are not on a straight line due to a curved road or the like, FIG.
As shown in FIG. 7, by using the wide positioning metal fitting 14 having a margin between the side surface of the frame 11 and the side edge portion 14c, the frame 11 can be similarly positioned and fixed.

In the illustrated embodiment described above, the top 14
The side edge part 14c was formed in both sides of a. However, for example, as shown in FIG.
c may be formed, and the side edge portion 14c may be located outside the frame pillar 11 (on the side opposite to the pavement location B) to fix the positioning metal fitting 14.

By the way, when pavement is performed by partitioning with the frame pillar 11 as described above, conventionally, the height of the frame pillar 11 is measured by a sensor running on the frame pillar 11, and paving is performed according to the height. there were. However, if such a method is performed in the above-described embodiment, the head of the fixing nail 15 protruding from the upper surface of the top 14a of the positioning fitting 14 becomes an obstacle. Therefore,
Considering this, for example, as shown in FIG.
A concave portion 14d is formed near the fixed nail insertion hole 14b on the top portion 14a of the positioning metal fitting 14, and the fixed nail insertion hole 1 is stretched between the ends of two adjacent frame pillars 11 as shown in FIG.
When the fixing nail 15 is inserted into the base 4b and the tip is driven into the roadbed 10, the concave portion 14d enters the gap s between the ends of the two frame pillars 11, and the head 15a of the fixing nail 15 is You may make it not protrude from an upper surface.

In the positioning bracket 14 shown in FIG.
Except for both sides of the concave portion 14d, the shape forms the side edge portion 14c. Then, as shown in FIG. 5, the lateral displacement of the frame post 11 is restricted by being sandwiched between the side edges 14c.

In the above-described embodiment, the fixing nail 15 is inserted into the fixing nail insertion hole 14b of the positioning metal fitting 14, passes through the gap s between the ends of the two civil engineering frame posts 11, and the tip ends in the roadbed 10. I tried to hit. However, in the present invention,
Not only when the fixing nail 15 is passed through the gap s between the ends of the civil engineering frame post 11, but also,
The tip may be driven into the roadbed 10 through the end.

[0021]

Therefore, according to the present invention, when paving a road, a pavement location is divided by a plurality of civil engineering frames,
A positioning bracket is hung between the ends of the two adjacent civil engineering frame pillars, inserted into the fixing nail insertion hole, and the positioning bracket is fixed with the fixing nail. The lateral displacement is regulated by the section, and the civil engineering frame pillar is positioned and fixed, so that the work of hammering in and pulling out the pile is eliminated, making paving work easier, and repairing with minimal damage to the roadbed Troublesomeness can be eliminated.

According to the third aspect of the present invention, when the positioning bracket is hung between the ends of the two civil engineering frame pillars, the concave portion enters between the ends of the two civil engineering frame pillars. When the fixing nail is inserted into the fixing nail insertion hole and the tip is driven into the roadbed, the head of the fixing nail does not protrude from the upper surface of the top of the positioning metal fitting. Therefore, similarly to the related art, the height of the frame pillar can be measured by the sensor running on the frame pillar, and paving can be performed according to the height.
