DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure of a building.

[0002]

2. Description of the Related Art Conventionally, there is a building in which a stone material is used as an exterior material. The building is formed by bonding a large number of plate-like stone materials to a base wall of the building such as reinforced concrete. Due to the large number of stones forming the outer wall, the building has a profound atmosphere.

[0003]

However, the structure in which the plate-like stone material is adhered to the base wall as described above is limited to buildings such as reinforced concrete, and is not applicable to wooden buildings. Cannot be applied. The reason is as follows. In the case of wooden buildings, the base walls vibrate significantly due to wind pressure, sound pressure, earthquakes, etc. compared to buildings made of reinforced concrete etc. Shaking occurs). Then, the vibration of the plate-like stone material bonded to the base wall portion causes excessive stress, and the stone material is cracked or falls off.

[0004] Therefore, an object of the present invention is to provide a structure in which a stone can be disposed on a wall surface of a wooden building.

[0005]

According to a first aspect of the present invention, there is provided a wall structure of a building, comprising: a base wall portion of the building; and a base wall portion of the building. A locking portion forming surface on which a plurality of locking portions are formed, directly or indirectly, and a substantially plate-like shape, on the back surface of which a locking portion corresponding to the locking portion of the locking portion forming surface is provided. And a stone material whose at least a front surface is formed of a stone material, wherein a locked portion of the stone material has a locking portion with respect to a locking portion of the locking portion forming surface. It is a stone wall surface structure of a building, wherein the stone wall material is locked and the stone wall material is disposed on the base wall portion.

[0006] In this specification, "front" means a side in a direction away from the base wall, and "back" means a side in a direction approaching the base wall. That is, when the present invention is applied to the outer wall surface of a building, the “front” is the side in the direction of “outside the building”, and the “back”
Is the side in the direction of "inside the building". On the other hand, when the present invention is applied to the inner wall surface of a building, the relationship described above is reversed.

[0007] The "stone decoration material" is not limited to the case where the entire surface is formed of stone material, but the case where only the front surface side is formed of stone material and the back surface is formed of another material. possible. The “stone” includes not only natural stone but also artificial stone.

The term “provided directly or indirectly with respect to the base wall portion” means that the outer or inner surface of the base wall portion is a locking portion forming surface (directly), Both the case where the other member is disposed outside or inside and the front surface of the other member is the locking portion forming surface (indirectly) is included.

In the wall structure of the present invention, the locked portion of the stone material is locked to the locking portion of the locking portion forming surface provided directly or indirectly on the base wall portion. , Stone coverings are placed against the base wall. Therefore, it is not necessary for the stone material to be adhered to the base wall. Since the stone material is not adhered to the base wall, even if the base wall of the wooden building vibrates due to wind pressure, sound pressure, earthquake, etc., the stone material is relatively attached to the base wall. Is prevented from being displaced (positionally displaced) and unreasonable stress is generated in the stone material (stone material). For this reason, the stone material (stone material) is prevented from cracking or falling off. In this way, in the wall structure of the present invention, a stone material (stone material) can be appropriately disposed on the wall surface of a wooden building. The present invention (Claim 1)
-All of Claim 3) can be applied also to the wall surface of buildings, such as reinforced concrete.

According to a second aspect of the present invention, there is provided the stone wall surface structure for a building according to the first aspect of the present invention, wherein the locking portion of the locking portion forming surface has a convex shape protruding in the front direction. Part, the upper end of which is in the form of a slope that gradually goes upward as it goes in the front direction, and the locked parts of the stone material correspond to the locking parts, This is a stone wall surface structure of a building, which is a concave portion that is concave in the direction, and the upper end portion of the concave portion gradually forms upward as it goes in the front direction.

[0011] The "front direction" and "upper end" of the stone material
“Upward” and the like are expressions based on a state in which the stone material is disposed on the base wall.

In the wall structure according to the present invention, the locking portion of the locking portion forming surface is a convex portion protruding in the front direction, and gradually rises upward as the upper end portion moves in the front direction. In response to this, the locked portion of the stone material is a concave portion that is depressed in the front direction, and gradually as the upper end portion moves in the front direction. It is a concave portion having an upward slope. For this reason, the convex portion is fitted into the concave portion, and the upper end of the concave portion comes into contact with the upper end of the convex portion, both of which form a slope, and the stone material (concave portion)
Is securely locked to the locking portion forming surface (convex portion) in a fall prevention state. For this reason, the effect of the invention according to claim 1 is more specifically obtained.

According to a third aspect of the present invention, there is provided a stone wall surface structure of a building according to the first or second aspect of the present invention, wherein only the front side of the stone exterior material is made of stone. It is a stone wall surface structure of a building that has been formed.

In the wall structure according to the present invention, of the stone materials,
Since only the front side is made of stone,
Since the other portions are formed of a material having a specific gravity lower than that of the stone material, the weight of the entire stone material is reduced as compared with the case where all the stone materials are formed of the stone material. For this reason, the weight load on a wooden building is reduced, and the present invention is more suitably applied to a wooden building.

Reference numeral 0 denotes a belt-like shape, which extends in the horizontal direction at a predetermined interval in the vertical direction. The front surface 32 (outer surface) of each convex portion 30 has a planar shape.

The upper end 34a of each protruding portion 30 has a slope that gradually rises from the base edge toward the leading edge (that is, toward the front direction). For example, the inclination angle (the angle with respect to the horizontal plane) is 25 degrees. The lower end 34b of each convex portion 30 is
It is almost horizontal.

As shown in FIGS. 1, 3 and 4, etc., the stone material 50 has a rectangular plate shape. The stone material 50 is formed by bonding a thin plate-shaped front side member 51A and a back side member 51B with an adhesive. The front side member 51A is formed of a stone material. Back member 5
1B is made of a material having a lower specific gravity than stone, such as synthetic resin or foam concrete.

As shown in FIGS. 1 and 5, the size of the stone material 50 is such that a plurality of stone materials 5
When 0 is provided, the dimensional relationship is such that a slight gap 58 is generated between the stone materials 50 adjacent in each of the vertical direction and the horizontal direction.

As shown in FIGS. 3B and 4, a plurality of concave portions 60 (corresponding to locked portions) are formed on the back surface 52 of the stone material 50 (ie, the back surface of the back member 51 B). Is formed. The number is, for example, three or four (the figure shows a case of three). Each concave part 60 is formed corresponding to each convex part 30 of the convex part forming plate 20.

That is, each concave portion 60 is formed so as to be recessed in the front direction from the back surface 52 of the stone material 50. Each concave portion 60 has a band shape, and extends in the horizontal direction at a predetermined interval in the vertical direction. The width (length in the vertical direction) of each concave portion 60 is formed longer than the width of each convex portion 30. The vertical interval between the concave portions 60 corresponds to the interval between the convex portions 30. The front surface 62 (the back surface) of each concave portion 60 has a flat shape.

The depth of each concave portion 60 corresponds to the length of protrusion of each convex portion 30. That is, the depth of each concave portion 60 is formed to be substantially the same as the protruding length of each convex portion 30.

The upper end portion 64a of each concave portion 60 corresponds to the upper end portion 34a of each convex portion 30 (that is, corresponding to each other), and moves from the base edge portion to the deep edge portion. The slope is gradually upward (ie, toward the front). For example, the inclination angle (the angle with respect to the horizontal plane) is 25 degrees. Each concave portion 60
The lower end portion 64b is substantially horizontal. The above description of the stone material 50 is based on a state in which the stone material 50 is disposed on the protruding portion forming plate material 20 (described below).

Each of the stone materials 50 is disposed on the protruding portion forming plate material 20 (and, consequently, on the base wall portion 10) as follows. As shown in FIGS. 4 to 5, each concave portion 60 of each stone material 50 is locked to each convex portion 30 of the convex portion forming plate 20. That is, first, each concave portion 60 of the stone material 50 is
The stone material 50 is positioned so that the convex portions 30 of the convex portion forming plate member 20 are fitted to each other (indicated by a two-dot chain line in FIG. 4). Then, in the fitted state, the stone material 50 is slightly lowered, and the upper end 64 a of each concave portion 60 of the stone material 50 abuts on the upper end 34 a of each convex portion 30 of the convex portion forming plate 20. To be. Each of the stone materials 50 is formed of a convex portion forming plate material 2.

At this time, as described above, the upper end 34a of each convex portion 30 and the upper end 64a of each concave portion 60 correspond to each other and gradually move upward as they move toward the front. Because of the slope shape, each stone material 50 is securely locked to the protruding portion forming plate material 20 and is prevented from falling.

As shown in FIGS. 1 and 5, in a state where a plurality of stone materials 50 are arranged on the protruding portion forming plate material 20,
A slight gap 58 is created between each of the stone materials 50 adjacent in each of the vertical and horizontal directions. The joint material is injected into the gap 58 to form the joint portion 80. As the joint material, gypsum, cement, silicon, or the like is applied.

As described above, the stone material 50 is disposed on the base wall 10 of the wooden building, and the outer wall surface of the wooden building is covered with the stone. Thus, the building has a profound atmosphere.

Further, in the above structure, the stone material (stone material 50) is not bonded to the base wall portion 10 but is locked to the base wall portion 10 (projection portion forming plate material). 2
0 is indirectly locked through 0)
The following effects are obtained. That is, the base wall portion 10 of the wooden building vibrates greatly due to wind pressure, sound pressure, an earthquake, or the like, as compared with the case of a building such as reinforced concrete. However, since the stone material 50 is not adhered to the base wall portion 10 but is only locked, the stone material 50 and the base wall portion 10 (the protruding portion forming plate material 20) are not fixed. Relative displacement (displacement) is possible, and generation of unreasonable stress on the stone material 50 (stone material) is prevented. For this reason, the stone material 50 (stone material) is prevented from cracking or falling off. As described above, in the above-described structure, the stone can be suitably disposed also on the wall surface of the wooden building.

In the above-described structure, as described above, the stone material 50 is made of the front member 51A made of stone.
And a back-side member 51B made of a material (synthetic resin, foam concrete, or the like) having a lower specific gravity than stone. As a result, the overall weight of the stone material 50 is lighter than that of a case where the entire stone material 50 is formed of a stone material. For this reason, the weight load on the wooden building is reduced by that much, and in this regard, the stone material is suitably disposed on the wall surface of the wooden building.

The above is merely an embodiment of the present invention, and it goes without saying that the present invention can be implemented in various modified forms based on the knowledge of those skilled in the art. For example, the stone material 50 may be entirely formed of a stone material. Further, the convex portion forming plate member 20 may not be provided, and the convex portion (30) may be directly formed on the outer surface 12 of the base wall portion 10.
