It is fixed by The connectors, hole anchor fittings, etc. are made of metal such as stainless steel.

Next, the operation of the above structure will be explained.

First, a hole is formed at a suitable location in the outer wall 3 of the concrete building 2 using a drill, and a hole anchor fitting 16 is driven into the hole anchor fitting 16, and a male screw member 18 is screwed into the hole anchor fitting 16. Also, two-tiered and three-tiered stones 1
Upper and lower vertical holes 5 and 6 and a flat groove-shaped mounting hole 4 are previously drilled in B and 1C, and the flat plate portion 10 of the connecting insertion member 9 is driven into the mounting hole 4, and
The positioning shaft 15 is inserted into the upper vertical hole 5 so as to be inserted into the through hole 12 of the flat plate portion 10. Then, the connecting tool 19 is attached to the male screw 11 of the proximal end protruding portion of the connecting insertion member 9.
Insert the hole 20 and washer 14 into the male screw 11 and tighten the nut 13.
By tightening the nut 13, the connecting insertion member 9 is pulled toward the concrete building 2 side via the male screw 11, and thereby the positioning shaft 15 is attached to the wall surface of the upper vertical hole 5. It is crimped, and the flat plate part 10 is prevented from coming off and firmly fixed. The lower end of the connector 19 is fixed by the male screw 11, so that the stone material 1 can be fixed. Next, after attaching the support fitting 24 to the outer wall 3, insert the tip of the other side piece 28 into the lower vertical hole 6 to position the first stage stone 1A, and then insert the hole 21 of the connector 19 into the male screw member 18. By latching it and fixing it with the nut 22 and washer 23, the first stone 1A is held suspended from the outer wall 3 via the connector 19. Next, the upper edge surface 7 of the first stone 1A
Place the second tier of stones 1B on top. At this time, a shaft 15 protrudes from the upper edge surface 7 of the first stage stone 1A, and the lower vertical hole 6 of the second stage stone 1B is inserted into this shaft 15 to position the stone 1B. At this time, a filling material (not shown) such as mortar or adhesive may be provided in advance in the upper vertical hole 5 of the first stage stone 1A and the lower vertical hole 6 of the second stage stone 1B, Alternatively, the upper edge surface 7 of the lower tier and the lower edge surface 8 of the upper tier may be bonded together. And the second stage stone 1B
The hole 21 of the connector 19 connected to the male screw member 18
and then tighten the nut 22 with a wrench (not shown) inserted from above to remove the second stone 1.
This is to fix B.

[0014] In this way, the stones 1C, 1D, . . . in three or four tiers are successively stacked and fixed.

As described above, in the above-mentioned embodiment, the positioning shaft 15 is inserted in the upper vertical direction so as to be inserted into the through hole 12 of the flat plate portion 10 of the connecting insertion member 9 inserted into the flat groove-shaped attachment hole 4. By inserting into the hole 5 and screwing the nut 13 onto the male screw 11 of the proximal end protruding portion of the connecting insertion member 9,
By tightening the nut 13, the connecting insertion member 9 is pulled toward the concrete building 2, whereby the positioning shaft 15 is crimped into the upper vertical hole 5, and the connecting insertion member 9 is pulled toward the concrete building 2.
By preventing the stones from falling off, the stones 1A, 1B, etc. placed above and below will not become unstable due to wobbling of the shaft 15, and can be assembled robustly. Since the joints will not be exposed, the aesthetic appearance can be improved. Further, since the mounting hole 4 is formed in the shape of a flat groove, the mounting hole 4 can be formed by simply cutting the mounting hole 4 with a cutting device such as a circular saw, and the drilling operation can be performed easily. Furthermore, as an effect of the embodiment, the connecting tool 1
The lower end of 9 is connected to the inner surface of the stone 1 and the stone 1 is attached to the outer wall 3.
By attaching it in a suspended state to the outer wall 3, it is possible to omit connecting the hanging fitting and the receiving fitting with bolts and nuts between the wall surface and the stone material as in the conventional technology. The gap width can be reduced to about 20 mm, and the work is easy because the connecting tool 19 can be connected to the wall 3 at a position above the stone 1. In addition, during construction, the male screw member 18 is fixed in advance to the hole anchor fitting 16 of the outer wall 3, the shaft 15 is fixed to the connecting insertion member 9 on the stone 1 side, and the lower part of the connecting tool 19 is fixed to the connecting insert member 9. After fixing to the insertion member 9, the stone 1 to which the connecting tool 19 is fixed is hooked to the male screw member 18 and the nut 22 is tightened, so it can be easily constructed without requiring any skill. .

FIGS. 6 and 7 show a second and third embodiment of the present invention, in which the same parts as in the first embodiment are designated by the same reference numerals and detailed explanation thereof will be omitted.

In the second embodiment, the hole 1 of the connector 19
A positioning taper part 31 is formed on the entire circumferential surface of the nuts 13, 20, and a positioning tapered part 32 is formed on the entire lower end surface of the nuts 13, 22.
When connecting to the wall 3 and the stone 1, when the nuts 13, 22 are tightened, the positioning taper portions 31, 32 of the nuts 13, 22 and the holes 19, 20 abut each other, and the holes 19, 20 are properly positioned and tightened. .

In the third embodiment, a stone material 1 is used as an inner wall and is fixed to a wooden pillar 33. In this case, four holes 34, 35, 36, 37 are formed at the upper end of the connector 19A.
are arranged side by side, the holes 34 and 37 at both ends are formed as screw holes, the two inner holes 35 and 36 are formed as circular holes, and the holes 34 and 39 are provided with perforation adjusting screws 38 and 39. The screws are inserted so that they can move forward and backward, and wooden screws 40 are inserted into the holes 35 and 36.
, 41 can be inserted loosely. When installing, the insertion ends of the left and right adjustment screws 38 and 39 are brought into contact with the pillar 33, and the installation position of the stone 1, which is positioned by inserting into the shaft 15 and the vertical hole 6, is properly adjusted, and then the wooden screws are screwed. 40,4
At 1, the connector 19 is fixed to the pillar 33. In this way, it can be applied to wooden buildings.
