Abstract

PURPOSE:To provide a structure having high resistant properties, such as stone by minimizing a sap between a wall surface and a structure. CONSTITUTION:A positioning shaft 18, a connection insertion tool 17 and a connector 22 are mounted to a stone material 1 where a male screw member 21 is fixed with a wall surface 3. A lower part vertical hole 6 of the stone material 1 is inserted into the positioning shaft 18 located at the stone material 1 at a lower stage than the first stone material 1 so that the position of the hole may be determined. The connector 22 is fixedly connected to a connection receiving means 17 at an upper location than the stone material 1 so that it may be fixed with the wall surface 3. This construction makes it possible to omit a connection work between the stone material 1 and the wall surface 3 and reduce the width of a sap between the stone material 1 and the wall surface 3, thereby simplifying the work. In addition, the connector 22 is made of a flat bar. One end of the connector fixed with the connection means 17 and the other end fixed with the male screw member 21 described above are tied with a middle section which shapes up an obtuse angle with the one end side and the other end side. A force which exerts the connector 22 from the stone material can be absorbed with its own elasticity.

It is fixed by a nut 34. The connecting tool, the hole anchor metal fitting, etc. are made of metal such as stainless steel.

Next, the operation of the above configuration will be described.

First, a hole is formed at a proper position on the outer wall 3 of the concrete structure 2 by a drill so as to be orthogonal to the outer wall 3, and a hole anchor metal fitting 19 is driven in, and a male screw member 21 is screwed into the hole anchor metal fitting 19. I'll do it. Therefore, the male screw member 21 is provided orthogonal to the outer wall 3.
Further, upper and lower vertical holes 5, 6 and a mounting hole 4 are preliminarily formed in the two-stage and three-stage stone materials 1B, 1C, and a hole anchor metal fitting 9 is driven into the mounting hole 4, and
The shaft 18 is inserted into the upper vertical hole 5 so as to be inserted into the through hole 15 of the hole anchor fitting 9. Then, a wrench or the like is attached to the tool anchoring portion 15A of the hole anchor metal fitting 9 to form a male screw member.
By screwing 16 into the female screw 11, the shaft 18 is crimped to the tapered surface 13 to fix the shaft 18, and the hole 14 is expanded by the crimping force to prevent the hole anchor fitting 9 from coming off. . Further, the male screw member 16 is inserted into the hole 23 and the connector 22 is fixed by the nut 25.

Next, after attaching the support fitting 28 to the outer wall 3,
Insert the tip of the other side piece 32 into the lower vertical hole 6 to make the first stone 1
A is positioned, and the hole 24 of the connector 22 is further inserted into the male screw member 21.
The first stage stone material 1A is held in a suspended state on the outer wall 3 via the connecting tool 22 by locking it with the nut 26 and the washer 27 and fixing it.
Next, the second-stage stone material 1B is placed on the upper edge 7 of the first-stage stone material 1A. At this time, a shaft 18 projects from the upper edge surface 7 of the first-stage stone material 1A, and the second-stage stone material 1 is attached to the shaft 18.
The lower vertical hole 6 of B is inserted to position the stone material 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 material 1A and the lower vertical hole 6 of the second-stage stone material 1B. Further, the lower upper edge surface 7 and the lower lower edge surface 8 may be bonded together. Then, the hole 24 of the connecting tool 22 connected to the second stage stone material 1B is hooked on the male screw member 21, and the nut
26 is tightened with a wrench (not shown) inserted from above to fix the stone material 1B of the second stage.

In this way, the stone materials 1C, 1D, ... Of three steps, four steps ...

As described above, in the above embodiment, the lower end of the connecting tool 22 is connected to the inner surface side of the stone material 1 and the stone material 1 is attached to the outer wall 3 in a suspended state. Since it is possible to omit connecting the hook and the bracket with the bolts and nuts between the wall surface and the stone material as described above, the outer wall 3
The gap width between the stone and the stone 1 can be reduced to about 20 mm,
Moreover, since the connecting tool 22 can be connected to the wall 3 at a position above the stone material 1, the work is simple, and further, no joints or the like appear on the surface side of the stone material 1 and the aesthetic feeling can be improved.

Further, the tapered surface 13 is formed at the inner tip of the hole anchor metal fitting 9, and the male screw member 16 is screwed to press the positioning shaft 18 onto the tapered surface 13 so that the shaft 18 can be fixed. , Stone materials 1A, 1 arranged vertically
B ... does not become unstable due to wobbling of the shaft 18, etc., and can be firmly assembled.

Moreover, in the construction, the male screw member 21 is fixed to the hole anchor metal fitting 19 of the outer wall 3 in advance, and the stone material 1
On the side, the hole anchor metal fitting 9 and the male screw member 16 together with the shaft
18 and fix the lower part of the connector 22 to the male screw member 16
After fixing the connecting member 22, the stone material 1 may be hooked on the male screw member 21 and the nut 26 may be tightened. Therefore, it is possible to easily perform the construction without skill.

Further, the flat plate-like connecting member 22 is a connecting insert 17
Since the lower part fixed to the upper part and the upper part fixed to the male screw member 21 are connected to each other by an intermediate part forming an obtuse angle with respect to the upper part and the lower part, the stone materials 1A, 1B ... If a couple is applied, a couple is applied at the lower part and the top of the connector 22, but the force applied to the connector 22 is its own due to the directionality in which the intermediate portion intersects this couple. It is absorbed by elasticity. Therefore, stone materials 1A, 1
Highly resistant to external force on B ... Moreover, since the stone materials 1A, 1B ... Are supported in a state of being suspended from the wall 3 of the building 2 by the connecting tool 22 projecting upward from the upper portion thereof, the support strength of the stone materials 1A, 1B. Is even more expensive.

Further, since the upper portion of the connecting member 22 is hooked on the portion of the male screw member 21 protruding from the wall 3 and is fixed by the nuts 25 and 26, the connecting member 22 is attached to the male screw member 21. Since the load of the stone material 1 is only applied via the, the male screw member 21 is less likely to come off than the wall 3,
The mounting strength can be increased.
