DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a stone used for a wooden pillar, an outer wall, or the like.

[0002]

2. Description of the Related Art A porch pillar for supporting the roof is provided in a stairwell provided outside the entrance room and covered with a roof. The wooden porch pillar is covered with mortar on the outer surface, and tiles, stones, and the like are put on the mortar to make up the porcelain.

[0003] In addition to such pillars, Japanese Patent Laid-Open Publication No. 63-73430 proposes a method of attaching a stone or the like to the outer wall of a building. In the mounting structure of the stone plate to the wall surface, a hole is formed in the lower small face of the stone plate, a metal fitting is attached to a tip of a metal fitting fixed to the wall, and a connecting screw screwed to the tip of the metal fitting is attached to the connecting screw. It is inserted into the hole and fixed.

[0004]

When the stone is stretched using mortar as in the above-mentioned conventional method, since the outer surface of the wood is covered with the mortar, the column itself becomes moist and condensation occurs, and the column is liable to rot. There was a problem. Moreover, when the column is deformed, cracks are generated in the mortar and the stone on the outer surface, which is not preferable in appearance.

In the above-mentioned mounting structure, the lower edge of the stone plate is placed and fixed on the metal fitting, and the weight of the stone plate is supported by the metal fitting. There has been a problem that a fixing material for fixing the latch to the wall surface becomes large. In addition, when a stone plate is fixed to a wooden column, if the column is deformed such as warping, local stress is applied to the stone plate via the metal fittings, and there is a possibility that a crack or the like may be generated in the stone plate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure for mounting a stone material having excellent durability by preventing the occurrence of dew condensation in a wooden building.

[0007]

According to a first aspect of the present invention, there is provided a stone mounting structure for stacking stones along side surfaces of a wooden building and fixing the stones to the side surfaces. Upper and lower vertical holes, vertical positioning shafts loosely inserted in the lower and upper vertical holes facing the upper and lower stones, and a base end side fixed to the side surface and a distal flat plate portion as Up,
A positioning metal fitting to be inserted between the lower and upper forefaces of the lower stone, and an insertion hole provided in a flat plate at the tip of the positioning metal and passing through the positioning shaft; And the lower part sandwiching the tip flat part,
A joint gap is formed between the upper and lower edge surfaces, a joint material having flexibility is filled in the joint gap, an elastic material is provided between a base end side of the positioning bracket and the side surface, and a base end of the positioning bracket is provided. On the side and the elastic material, through holes for inserting wood screws are respectively formed, and the positioning fitting is fixed to the side surface by the wood screws inserted into these through holes, and the wood screws have a countersunk head, The flat end portion of the positioning metal fitting is provided so as to be tiltable with respect to the side surface by elastic deformation of the elastic material.

[0008]

According to the structure of the first aspect, the air layer formed between the stone material and the side surface can prevent dew condensation occurring on the side surface of the wooden building, thereby preventing its decay and deformation. Also, since the positioning shaft is loosely inserted into the vertical hole, and the joint gap formed by the flat plate portion at the tip is filled with a flexible joint material, even if the side surface is deformed and the positioning bracket is displaced, this is not affected. The stone can be absorbed by moving in the gap between the vertical hole and the positioning shaft, and further within the range of the gap. In addition, even if the side surface is deformed and the direction of the positioning fitting changes, the elastic material is elastically deformed and the tip flat plate tilts with respect to the side surface, so that no excessive force is applied to the stone material and the side surface. In addition, the tilting of the positioning fitting with respect to the wood screw is facilitated.

The stone material 11 fixed on the side surface 3A of the porcelain has an air layer 12 formed between the stone material 11 and the porch pillar 3, which communicates with the outside through the entrance roof 4. The replacement of the air is performed, and the dew condensation on the side surface 3A of the porch column 3 is prevented, so that the porch column 3 can be prevented from being rotted by moisture. Even if deformation such as warpage occurs in the porch column 3 over time, the tip flat plate portion 20A tilts with respect to the side surface 3A due to the elastic deformation of the elastic material 32, as shown by the dashed line in FIG. The displacement of the stone 11 is prevented. Further, the positioning shaft 17 moves in the upper and lower vertical holes 15 and 16,
The stone material 11 itself is also raised by the joint material 30 having flexibility.
Since it is possible to finely move within the gap between the lower vertical holes 15, 16 and the positioning shaft 17, the displacement of the positioning bracket 18 can be absorbed,
The stone 11 does not crack. Also, even if an earthquake or the like occurs, the stone material 11 is provided by the flexible joint material 30.
Since itself can move within the range of the gap between the upper and lower vertical holes 15 and 16 and the positioning shaft 17, it is possible to prevent the stone 11 from cracking.

As described above, according to the first embodiment, stone materials 11 are stacked along the side surface 3A of the porch pillar 3 as a wooden building, and the stone material 11 is fixed to the side surface 3A.
In the mounting structure 11, the upper and lower vertical holes 15 and 16 pierced in the upper and lower edge surfaces 13 and 14 of the stone 11 and the lower and upper vertical holes 16 and 15 of the upper and lower stones 11 and 11 facing each other. And a positioning bracket 18 for fixing the base end side to the side surface 3A and inserting the front flat plate portion 20A into the upper and lower stones 11, 11 and between the upper forefaces 14, 13. And a flat plate portion at the tip of the positioning bracket 18.
20A is provided with an insertion hole 28 through which the positioning shaft 18 is inserted, and the air layer 12 is provided between the side surface 3 and the back surface of the stone 11; 29, the joint gap 29 is filled with a joint material 30 having flexibility, and an elastic material 32 is provided between the base end side of the positioning bracket 18 and the side surface 20A. Through holes 24 and 33, through which the wood screws 23 are inserted, are formed in the material 32,
The positioning bracket 18 is fixed to the side surface 20A by a wood screw 23 inserted through the through holes 24 and 33. The wood screw 23 has a dish-shaped head 23A, and the flat plate portion 20A of the positioning bracket 18 is elastically deformed by the elastic material 32. It is provided so as to be tiltable with respect to the side surface 3A. The air layer 12 formed between the stone material 11 and the side surface 3A can prevent dew condensation on the side surface 3A of the porch column 3 and prevent its rot and deformation. it can. In addition, since the positioning shaft 18 is loosely inserted into the vertical holes 15 and 16 and the joint gap 29 formed by the tip flat plate portion 20A is filled with the flexible joint material 30, the side surface 3A is deformed and the positioning fitting 18 is formed. Even if a displacement occurs, the gap between the vertical holes 15, 16 and the positioning shaft 17
Furthermore, the stone 11 itself can be absorbed by moving within the range of the gap. Further, the lowermost stone material 11 is placed on the earth concrete 1 serving as the mounting surface, and the lower surface stones 13 and 14 are sequentially stacked with the tip flat plate portion 20A interposed therebetween. Since the positioning in the plane direction of 11 is performed, unlike the conventional method in which the load of the stone is supported by the metal fitting as in the related art, the load of the stone is not applied to the positioning metal 18, so that it is not necessary to use a large metal fitting. For this reason, the stone 11 can be positioned and fixed by the minimum two positioning brackets 18. Moreover, even if the side surface 3A is deformed and the direction of the positioning fitting 18 is changed, the elastic material 32 is elastically deformed and the tip flat plate portion 20A is tilted, so that no excessive force is applied to the stone material 11 and the side surface 3A. Cracks and cracks can be prevented from being generated in the porch column 3 through the wood screws 23. Further, even if the side surface 3A is deformed in the plane direction, it can be absorbed by the elastic material 32. Further, since the wood screw 23 has the dish-shaped head 23A, the tilting of the positioning fitting 18 with respect to the wood screw 23 becomes easy.

Further, as an effect of the embodiment, since the bracket 19 and the mounting piece 20 are fixed through the elongated holes 27, the insertion holes 28 at the tips are aligned with the upper vertical holes 15 so that the two can be easily formed. Can be fixed. Furthermore, the upper part of the air layer 12 communicates with the inside of the entrance roof 4, so that dew condensation on the porch column 3 can be prevented well. Furthermore, by surrounding the slab stone 2 with the stone material 11, the slab stone 2 is not exposed, and the beauty of the area around the entrance can be enhanced. Further, since the positioning fitting 18 can be easily attached via the wood screw 23, it can be used as a repair work of the existing porch column 3. The positioning shaft 17 is inserted into the through hole 28 of the flat plate portion 20A.
Is loosely inserted, so that the positioning bracket 18 can swing horizontally about the positioning shaft 17.
