7 is engaged with the engagement hole 19 of the other L-shaped bracket 16, and the engagement hole 19 of the one L-shaped bracket 16 is
1 to form a frame-shaped connection fitting 15, and as shown in FIG. 1, the through holes 18, 18 are inserted into the threaded portions 12 b, 13 b of the threaded rods 12, 13. The nuts 20, 20 are screwed into the ends of the threaded portions 12 b, 13 b from inside the connection fitting 15. In this case, the width W1 in the short direction of the connection fitting 15 is set to a width (gap) for preventing the nuts 20 and 20 from idling, and the nuts 20 and 20 can be rotated via the connection fitting 15. The L-shaped bracket 1
Assembling of six and sixteen may be performed after each of the through holes 18 and 18 is inserted into each of the screw parts 12b and 13b.

等の効果を奏する。As described above, according to the present invention, the gap between the opposing concrete blocks can be easily adjusted, and the arrangement of the concrete blocks can be easily and accurately performed. Further, since the connecting fitting is assembled by engaging a pair of separately formed L-shaped fittings with each other, the work of engaging with the threaded rod in a narrow place becomes easy. Moreover,
Since the connection metal fitting when assembled in a frame shape is engaged with the nut screwed into the screw rod, two nuts facing each other can be rotated by rotating the connection metal fitting. In addition, since the tip of the engaging projection of the L-shaped bracket is inclined outward, the inclined portion acts in a direction of bringing the pair of L-shaped brackets closer to each other when a load is applied, and is assembled in a frame shape. The connected metal fitting is prevented from being inadvertently disassembled by the load when rotating the nut.
And so on.
