Description

Description: TECHNICAL FIELD The present invention relates to a stone plate used as a surface decorative material for the inner and outer walls of buildings, columns, floors, and the like.

<Prior Art and Problems Thereof> As is well known, stone plates such as marble, granite, coal and sedimentary rock are widely used as a surface decorative material for the interior and exterior walls, columns and floors of buildings, especially high-grade buildings. In such a stone slab construction, mortar or adhesive (for example, epoxy adhesive for stone slab) is usually applied to both the underside surface of the outer wall and the like and the backside of the slab, and then the stone board is pressure-bonded to the underside. To do.

However, in the past, the slab was sufficiently firmly held during construction, but the slab retaining force decreased due to aging, and the slab fell off frequently. The reason why the stone plate holding power decreases is (a) the water that has penetrated into the base material, etc. freezes to increase the volume and generates a force to push the stone plate apart. (B) The base material, the adhesive mortar or adhesive, and the stone material Since the coefficient of thermal expansion differs, the sticking mortar or adhesive may be fatigued due to expansion and contraction due to temperature change.

<Technical problem of the invention> The present invention has been made in view of the above circumstances, and to improve the shape of the stone material, it is possible to ensure a sufficient stone plate holding force for a long period of time. , And its technical issues.

<Solution to the Invention> According to the present invention, at least two opposing side surfaces are chamfered at a holding inclined surface that is inclined downward and outward, and at a boundary corner portion between the holding inclined surface and the surface. There is proposed a surface decorative stone plate having an inclined surface formed by processing.

<Operation of the Invention> According to the stone plate of the present invention, the holding inclined surface is partially embedded by a sticking mortar or the like, or the holding inclined surface is mechanically locked by the locking metal fitting driven into the base. Therefore, it is possible to secure a sufficient stone plate holding force for a long period of time.

<Specific Examples of the Invention> Hereinafter, preferred specific examples of a stone plate constructed according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the slab 2, which may be a square or rectangle of suitable size, has four sides 4, 6, 8 and
Having 10. Two of the side surfaces 4, 6, 8 and 10 facing each other are upright surfaces substantially perpendicular to the surface 12. However, the remaining two opposite sides 6 and 10 include bevels. Referring to FIG. 2 together with FIG. 1, the two side faces 6 and
Each of the 10 has inclined surfaces 14 and 16 that form a retaining inclined surface.
And upright surfaces 18 and 20. Bottom edge (ie back side)
The upstanding surfaces 18 and 20 located at are substantially perpendicular to the surface 12, while the sloping surfaces 14 and 16 slope downwardly outward. The inclination angle θ of the inclined surfaces 14 and 16 may be about 30 to 60 degrees.

In the illustrated embodiment, each of the two side surfaces 6 and 10 has the same shape over its entire length and has sloped surfaces 14 and 16, but if desired, its longitudinal direction. It is also possible to have inclined surfaces 14 and 16 in only a part of and the rest to have only upright surfaces which extend substantially perpendicular to the surface 12 from the upper end to the lower end. Also, the two side surfaces 4 and 8 can be made to have inclined surfaces 14 and 16 like the two side surfaces 6 and 10.

Further, in the illustrated stone plate 2, as in the case of the conventional stone plate,
4 upper edge ridges (ie surface 12 and 4 sides 4, 6, 8 and 10)
A yarn surface (inclined surface) 22 is formed by subjecting the yarn chamfering process to a boundary corner portion between and.

The stone plate 2 as described above can be conveniently manufactured as follows. That is, as shown in FIG. 3, a relatively large slab material 24, which may be cut from a natural stone by a known cutting method, has a relatively wide rotation whose outer peripheral portion has an isosceles triangular cross section. By the cutting wheel 26,
A plurality of grooves 28 having an isosceles triangular cross section are formed in parallel at predetermined intervals. Further, on both opposite edges of the stone plate material 24, a half width groove 30 whose one side surface is opened is formed by using substantially half of the rotary cutting grindstone 26 in the width direction. Then, as shown in FIG. 4, the stone plate material 24 is cut along the center of each of the grooves 28 with a relatively narrow rotary cutting grindstone 32. Then, when the required thread chamfering is performed, a plurality of stone plates 2 as shown in FIGS. 1 and 2 in which the inclined surfaces 14 and 16 are defined by the side walls of the groove 28 or the half-width groove 30 are formed. Produced.

FIG. 5 illustrates an example of a construction method for applying the stone plate 2 illustrated in FIGS. 1 and 2 to a wall surface such as an outer wall of a building.
In this construction example, first, as in the case of using a conventional stone board, the surface of the wall surface foundation 34 and the back surface of the stone board 2 are adhered with mortar 36 (or an appropriate adhesive) to apply the foundation 34. The pressure plate 2 is pressure-bonded to the surface. At this time, between the side surfaces 6 and 10 of the adjacent stone plate 2 having the inclined surfaces 14 and 16 and the upright surfaces 18 and 20, for example, 5 to 5 between the upright surfaces 18 and 20.
Leave a space of about 10 mm. Next, an additional adhesive mortar 38 (or an appropriate adhesive agent) is filled in such a space, and at least the lower portions of the inclined surfaces 14 and 16 are thus embedded. After that, a makeup joint mortar 40 is applied to the surface of the additional adhesive mortar 38.

As can be easily understood by referring to FIG.
The stone plate 2 applied to the wall surface base 34 as described above is inclined by the additional adhesion mortar 38 integrally joined to the adhesion mortar 36 applied to the wall surface base 34.
At least the lower part of the slab is buried, and thus, the holding force of the stone plate 2 is significantly strengthened, and a sufficient holding force is secured for a long period of time.

FIG. 6 shows another example of the construction method for applying the stone plate 2 shown in FIGS. 1 and 2 to the wall surface such as the outer wall of the building. Also in this construction example, first, as in the case of using a conventional stone board, the mortar 36 (or an appropriate adhesive agent) is applied to the front surface of the wall surface underlayer 34 and the back surface of the stone board 2 to apply the underlayer 34. The stone plate 2 is pressure-bonded to the surface. In this case,
Sloping surfaces 14 and 16 and upright surfaces 18 and
A space of about 5 to 10 mm is left between the side surfaces 6 and 10 having 20, for example, the upright surfaces 18 and 20. Next, the legs of the locking metal fittings 42 having a substantially T-shaped cross section are passed through the above-mentioned intervals to form the base.
Drive it into 34, and attach the head of the locking metal fitting 42 to the inclined surfaces 14 and 16 of the stone plate 2.
Abut or approach. Advantageously, the lower surface of the head of the locking fitting 42 is an inclined surface corresponding to the inclined surfaces 14 and 16 of the stone plate 2. A plurality of locking metal fittings 42 having a comparatively small joint direction dimension can be driven at intervals in the joint direction. Alternatively, it is possible to drive an elongated locking metal fitting 42 extending continuously in the joint direction. Further, if desired, the locking metal fitting 42 may be driven into the base 34 prior to the pressure bonding of the stone plate 2, and then the stone plate 2 may be pressure bonded to the surface of the base 34. In this case, the inclined surfaces 14 and 16 of the stone plate 2 can be inserted between the base 34 and the head of the locking fitting 42 from above or below. After that, 40 makeup mortar is applied.

In such a construction example, a locking metal fitting in which the inclined surfaces 14 and 16 of the stone plate 2 applied to the wall surface base 34 are driven into the wall surface base 34
It is mechanically locked by 42, thus the holding force of the stone plate 2 is greatly strengthened, and a sufficient holding force is secured for a long period of time.

<Effects of the Invention> In the surface decorative stone plate of the present invention, at least two opposing side surfaces have a holding inclined surface that inclines outward downward, and a boundary between the holding inclined surface and the surface. And an inclined surface formed by chamfering the corner portion. The stone plate according to the present invention having the above structure,
Similar to the conventional stone plate, in addition to being pressure-bonded to the underlying surface such as the outer wall through the adhesive mortar, in addition,
At least the lower part of the inclined surface for holding can be buried by filling the space between the adjacent stone plates with the space between them and filling the space with the mortar. In addition to the conventional stone plate, the stone plate according to the present invention is, in addition to being pressure-bonded to the surface of the underlayer such as the outer wall, for example, by pasting mortar, the stone plate according to the present invention further has a space between adjacent stone plates through the gap. It is possible to mechanically lock the inclined surface for holding by driving the locking metal piece into. As a result, the holding power of the stone plate is significantly strengthened, and a sufficient holding force of the stone plate is secured for a long period of time.
