DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. FIG.
The L-shaped block 11 is commercially available as a secondary concrete product, and has a vertical portion 11y and a bottom portion 1.
The angle between 1x is approximately 90 degrees. A plurality of concrete pouring holes 12 penetrating the bottom portion 11x,
Two fixing holes 13 are formed. The vertical portion 11y
Natural stones or the like may be provided on the outer surface of.

Next, the lower concrete structure 10A
Will be described. First, FIGS. 1 and 3
In the above, concrete 21 so-called stecon is cast on the ground surface G, and the anchor bolt 22 is pushed in while the concrete 21 is soft. When concrete 21 has hardened,
The L-shaped block 11A is placed on both side surfaces, and the outer surface of the vertical portion 11y is made to follow the outline of the concrete structure 10A.

Next, the anchor bolt 22 is inserted into the fixing hole 13, and the washer 23 and the abutment 24 are inserted into the anchor bolt 22. Since the lower surface of the abutment 24 is formed with a spherical spherical seat, even when the crossing angle between the anchor bolt 22 and the L-shaped block 11A fluctuates, it is in contact with the washer 23 at a fixed position. Then, if the nut 25 is screwed onto the anchor bolt 22, the L-shaped block 11A is fixed. Fixing device 2
Reference numeral 0 denotes an anchor bolt 22, a washer 23, a patch 24, and a nut 25. In the first embodiment, the contact tool 24 and the nut 25 are formed separately, but they are integrally connected to each other to form the nut 25 having a spherical seat.
It may be.

Next, concrete 26 is cast between the L-shaped blocks 11A on both sides. The height of the upper surface of the concrete 26 is larger than the upper end surface of the L-shaped block 11A by a dimension H.
One lower. The poured concrete 26 is filled into the lower surface of the L-shaped block 11A through the concrete injection hole 12 as shown by an arrow A in FIG. 3 and is also filled into the fixing hole 13 as shown by an arrow B. You. Concrete 26
Is cured, the lowermost structure 10A is formed.
Before the concrete 26 hardens, the upper structure 1
The anchor bolt 22 for fixing 0B is pushed in.

Next, a procedure for forming the upper structure 10B will be described. The mold block 11B is placed on the upper surface of the lower structure 10A along the outline. At this time, the lower end of the vertical portion 11y is in contact with the upper end of the lower L-shaped block 11, and the tip of the bottom 11x is in contact with the upper surface of the concrete 26. In addition, the concrete 21 for positioning may be suitably cast on the lower surface of the L-shaped block 11B (see FIG. 3). Note that the gradient of the L-shaped block 11B (the angle α
1) is determined by the height difference H1 between the L-shaped block 11A and the concrete 26. That is, the angle α1 decreases as H1 decreases, and the angle α1 increases as H1 increases.

The anchor bolt 22 is inserted into the fixing hole 13 of the L-shaped block 11B. Next, in the same manner as described above, the washer 23 and the patch 24 are inserted into the anchor bolt 22, and the nut 25 is screwed to the anchor bolt 22, thereby fixing the L-shaped block 11B. Next, concrete 26 is cast between the L-shaped blocks 11B on both sides. The distance H2 between the height of the upper surface of the concrete 26 and the upper end surface of the L-shaped block 11B is
It is set in accordance with the gradient α2 of the upper L-shaped block 11C. That is, when α1> α2, H1> H2 is set.
When the concrete 26 hardens, the upper concrete structure 10B is formed.

In the above procedure, the concrete structure 10B is read as the lower concrete structure, and the upper concrete structures 10C and 10D are sequentially formed.
In the uppermost concrete structure 10D, the concrete 26 is cast to the same position as the height of the L-shaped block 11.
