Description

The present invention relates to a method for fixing an inorganic plate, particularly a thin and large ceramic plate to a skeleton such as a wall, and a jig for that purpose, and more specifically, it is carried out in addition to a fixing means for attaching the inorganic plate with an adhesive or the like. , A method for preventing the falling off, and a jig for that purpose.

Inorganic boards such as tiles are widely used as interior or exterior materials. The construction of these inorganic boards on the skeleton is performed by sticking them with an adhesive or mortar. Furthermore, recently, large ceramic plates that can reduce joints and realize simplification of construction and diversification of designs have been put into practical use and widely used, and even for such large ceramic plates, the construction is performed with adhesives, etc. It is common to stick with.

When such an inorganic plate, particularly a large ceramic plate, is installed on a wall surface or the like, it is necessary to prevent the detachment and the damage caused by the detachment even if peeling or cracking occurs over time. Many large ceramic plates are thin and lightweight, but especially when a large ceramic plate is used as an exterior material, it is important to have a construction system that can prevent the large ceramic plate from falling off and the damage caused by the falling off.

As such a construction system, in addition to sticking with an adhesive or the like, a hole is made in an inorganic plate and fixed with a tapping screw or the like. However, if the interior / exterior material has a decorative surface, the holes and screw heads may impair the decorative surface design.

As a construction method that does not impair the design of the decorative surface, for example, a non-through hole is provided on one side of the inorganic plate, and the entire cylindrical coiled portion is inserted into this hole to repel the coiled portion in the expanding direction. A method of fixing to the hole by a frictional force based on a force has been proposed (Japanese Unexamined Patent Publication No. 8-68183, Patent Document 1). This method requires a hole of a certain depth to insert the coil into the hole. Further, it has been proposed to fix the building board to the non-through hole by using a locking piece having a specific structure (Japanese Patent Laid-Open No. 11-159102, Patent Document 2), but this locking piece is the inner wall of the non-through hole. Since the structure is in contact with points, it is considered that the locking force is limited. Therefore, it can be said that there is still a demand for a construction method that does not impair the design of the decorative surface, especially a method for fixing a thin and large inorganic plate.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a method of fixing an inorganic plate to a skeleton according to the present invention. In FIG. 1, the inorganic plate 1 is provided with a non-through hole 2, and the non-through hole is provided with a hole snap ring 3 (hereinafter, may be simply referred to as a “snap ring”, but unless otherwise specified, a “hole” is provided. (Meaning "snap ring") is inserted and fixed. A wire rod 4 as a fixing member is coupled to the fixed snap ring 3, and is fixed to a skeleton such as a wall at the end of the wire rod 4 on the opposite side to the end fixed to the snap ring 3. In the aspect of this figure, the wire rod 4 is a ring, and a fixture 5 such as a screw or an anchor bolt is driven into the ring (not shown), and the inorganic plate 1 is fixed. Apart from this fixing, the surface of the inorganic plate 1 provided with the non-through hole 2 is fixed to the skeleton by an adhesive. The fixing method according to the present invention may be applied alone as a method of fixing the inorganic plate to the skeleton, but the inorganic plate 1 is fixed by such two means and is fixed by an adhesive or the like due to deterioration over time. Even if the amount is insufficient, there is another fixing means using a snap ring, so that it can be prevented from falling off or damage caused by the falling off. That is, according to the present invention, there is provided a method for fixing the inorganic plate to the skeleton in a duplicated manner.

The fixing method according to the present invention will be described below for each step.
(A) Step of preparing an inorganic plate The inorganic plate fixed by the method according to the present invention is made of, for example, ceramics, stone, or glass. According to one aspect of the present invention, in the present invention, the inorganic plate is preferably used as a flat plate as a finishing material for exterior or interior walls, floors, ceilings, cabinet surface materials, and counters. Although the size is not limited, the fixing method according to the present invention can be a duplicated fixing method of the inorganic plate to the skeleton as described above, and is therefore preferably applied to a relatively large inorganic plate. .. According to one aspect of the present invention, the inorganic plate has a short side of more than 300 mm and an area of more than ^{900 cm 2.} The length of the short side of the inorganic plate preferably has 600 mm or more, more preferably 900 mm or more.

Further, according to a preferred embodiment of the present invention, the fixing method according to the present invention can be applied to a relatively thin inorganic plate. As described above, the non-penetrating holes are provided on the surface opposite to the decorative surface so as not to impair the design of the decorative surface, but in a thin inorganic plate, the non-through holes must be shallow. In order to reduce the weight of a large ceramic plate, for example, the thickness is set to about 3 mm or more and about 15 mm, preferably about 8 mm to 10 mm. From the viewpoint of the influence on the strength of the inorganic plate, it is desirable that the depth of the non-through hole is about half or less of the thinness. In the fixing method according to the present invention, even relatively shallow non-through holes in such a thin inorganic plate can be applied. Specifically, for example, it can be applied to the case where the depth of the non-through hole is 6 mm or less. The diameter of the non-through hole is preferably 6 mm or more and 80 mm or less, more preferably 8 mm or more and 60 mm or less, and further preferably 10 mm or more and 50 mm or less.

FIG. 2A is an enlarged view of the non-through hole 2 provided in the inorganic plate 1 of FIG. Further, FIG. 2B is an enlarged cross-sectional view of the non-through hole 2. In the embodiment shown in the figure, the non-through hole 2 is substantially circular and has an inner wall surface 21 substantially perpendicular to the surface of the inorganic plate. According to one aspect of the present invention, the inner wall surface 21 of the non-through hole 2 is not limited to being substantially vertical, and for example, its cross section has a dovetail hole / inverted C shape as shown in FIG. 2 (c). In this case, the inner wall surface 21 is not perpendicular to the surface of the inorganic plate. In the present invention, the snap ring comes into contact with the inner wall surface in the circumferential direction and locks. The snap ring comes into contact with the substantially vertical inner wall surface as shown in FIGS. 2 (a) and 2 (b) in the circumferential direction, and is engaged mainly by frictional force. Further, in the case of a hole having a shape as shown in FIG. 2C, the hole is brought into contact in the circumferential direction near the portion having the smallest diameter near the surface of the inorganic plate, and is locked mainly by a catching force. Both aspects are included in the present invention.

The bottom surface 22 of the non-through hole 2 shown in FIGS. 2A and 2B may be flat, but is not particularly limited as long as it does not significantly hinder the engagement of the snap ring fed.

The inorganic plate according to the present invention may have a glaze layer on its surface. The components of the glaze are not particularly limited. The glaze layer may be formed by either glazing after molding and firing integrally with the molded body, or by glazing the fired body (temporary fired body) and then firing. Further, a drying step may be provided before and after the glazing.

(B) Process of Preparing a Snap Ring FIG. 3 is a diagram showing an example of a hole snap ring used in the method according to the present invention. In FIG. 3A, the snap ring 3 has a structure in which a spring body 31 having a circular outer peripheral shape with a part cut off extends from one end of a connecting portion 32. The circular spring body 31 has an outer diameter slightly larger than the diameter of the non-through hole provided in the inorganic plate 1, has a predetermined thickness, and has a side surface 33 thereof. A hole (lug) 34 is provided in each of the cut ends of the spring body 31, and a snap ring plier is inserted into the hole (lug), and a force is applied so as to reduce the outer diameter to distort the ring and non-penetrate the inorganic plate. Insert into the hole. When the pliers are removed and the spring body 31 is released, a force (elasticity) that tries to return to the original shape acts, the spring body 31 expands the outer diameter toward the inner wall surface of the non-through hole, and the side surface 33 is the inner wall surface. It is pressed against 12 in the circumferential direction, and the snap ring is locked in the non-through hole by this frictional force. According to a preferred embodiment of the present invention, the side surface 33 of the snap ring is in contact with the inner wall surface 12 along the circumferential direction. By making contact on the surface, it is locked in the non-through hole with a stronger frictional force. Further, when the non-through hole has a shape as shown in FIG. 2C, a part of the side surface 33 of the spring body 31 is located near the smallest diameter portion near the surface of the inorganic plate as described above. It contacts in the circumferential direction and is locked. It is also possible to distort the ring so that the outer diameter becomes smaller by directly applying an external force to, for example, a standing piece provided in the spring body 31 without providing the hole 34.

The connecting portion 32 is provided with a hole 35 for connecting the connecting material, for example, penetrates the wire rod which is the connecting material, and fixes the wire rod to the connecting portion 32 by an appropriate fixing means. According to one preferred embodiment of the present invention, as shown in FIG. 3B, the connecting portion 32 preferably rises from the spring body portion and has a rising portion 36 for that purpose. According to a preferred embodiment of the present invention, the connecting portion 32 is preferably held near the center of the non-through hole when the snap ring is inserted into the non-through hole, and more preferably the hole 35 is non-penetrating. It is preferably located near the center of the hole. That is, the connection portion 32 is preferably provided on the center side of the snap ring rather than the side surface 33 of the spring body 31, and is not on the outer side surface 33 of the spring body 31 but on the center of the snap ring of the spring body 31. It is more preferable to extend from the inner side facing toward the center of the snap ring. With such a configuration, it is possible to withstand the pulling force from the vertical and horizontal directions in a direction substantially parallel to the surface of the inorganic plate 1 having the non-through hole 2 from the connecting material fixed to the skeleton to the snap ring. Further, even if a tensile force in the direction perpendicular to the surface is applied, the snap ring is less likely to fall out from the non-through hole. The effect of being less likely to fall off can be further enhanced by providing a rising portion 36 that can be expected to have a buffering effect.

FIG. 4 is a diagram showing another aspect of the snap ring according to the present invention, in which the same or corresponding portions as those of the snap ring shown in FIG. 3 are designated by the same reference numerals. That is, it has a structure in which two pieces of the spring main body 31 are extended from both ends of the connecting portion 32. The circular shape formed by the two spring bodies 31 has an outer diameter slightly larger than the diameter of the non-through hole provided in the inorganic plate 1. Further, the spring body 31 has a predetermined thickness and has a side surface 33 thereof. A hole (lug) 34 is provided at each end of the two pieces of the spring body 31, and a snap ring plier is inserted into the hole (lug), and a force is applied so as to reduce the outer diameter to distort the ring, and the non-inorganic plate is not used. Insert into the through hole. When the pliers are removed and the spring body 31 is released, a force (elasticity) that tries to return to the original shape acts, the spring body 31 expands the outer diameter toward the inner wall surface of the non-through hole, and the side surface 33 is the inner wall surface. It is pressed against 12 in the circumferential direction, and the snap ring is locked in the non-through hole by this frictional force. Further, when the non-through hole has a shape as shown in FIG. 2C, a part of the side surface 33 of the spring body 31 is located near the smallest diameter portion near the surface of the inorganic plate as described above. It contacts in the circumferential direction and is locked.

The connecting portion 32 is provided with a hole 35 for connecting the connecting material, for example, penetrates the wire rod which is the connecting material, and fixes the wire rod to the connecting portion 32 by an appropriate fixing means. According to one preferred embodiment of the present invention, as shown in FIG. 4B, the connecting portion 32 preferably rises from the spring body portion and has a rising portion 36 for that purpose. Even in this embodiment, the connecting portion 32 is preferably held near the center of the non-through hole when the snap ring is inserted into the non-through hole, and more preferably the hole 35 is the non-through hole. It is preferably near the center.

The snap ring shown in FIG. 4 has a structure in which two pieces of the spring body 31 are extended from the connecting portion 32. That is, the snap ring shown in FIG. 3 has two pieces of spring bodies extending from one end of the connecting portion 32, while in the embodiment shown in FIG. 4, the two ends of the connecting portion. It has two pieces of spring bodies extended from each. Further, according to the present invention, it is also possible to adopt a structure in which more than two pieces of the spring body 31 extend from the connecting portion. The diameter of the snap ring according to the present invention is preferably 6 mm or more and 90 mm or less, more preferably 8 mm or more and 70 mm or less, and further preferably 10 mm or more and 55 mm or less.

According to another aspect of the present invention, the connecting portion connected to the skeleton may be configured as a member integrally extended from the connecting portion of the snap ring. That is, in the snap ring shown in FIGS. 3 and 4, the connecting portion and the connecting material may be integrated to form a stretched portion extending integrally from the connecting portion. 5 and 6 are views showing an example of such a snap ring, in which FIG. 5A is a top view and FIG. 6B is a side view. It has a stretched portion 37 integrated with the stretched portion 37, has an end portion 38 at the end of the stretched portion 37, and is provided with a fixing hole 39 for fixing to the skeleton in the center thereof. In this aspect, the step described later in connecting the connecting material to the connecting portion of the snap ring in the aspects shown in FIGS. 3 and 4 can be omitted.

(C) Step of inserting the snap ring The snap ring is inserted into the non-through hole by applying a force to the spring body of the snap ring to distort its shape and reduce its outer diameter. As described above, in the snap ring of the aspects shown in FIGS. 3 and 4, a hole 34 is provided as a starting point for applying a force that distorts the shape. Jigs for fitting snap rings are commercially available as snap ring pliers and the like, and such jigs can be used to apply force to the spring body to reduce the outer diameter.

When the outer diameter of the snap ring is made slightly smaller than the non-through hole, the snap ring is inserted into the non-through hole. After insertion, stop applying force and release the spring body. Then, the spring body expands the outer diameter toward the inner wall surface of the non-through hole due to its elasticity, whereby it comes into contact with the inner wall surface of the non-through hole in the circumferential direction, and the snap ring is locked. FIG. 7 is a cross-sectional view of a snap ring locked in a non-through hole. In the figure, the snap ring 2 of the embodiment shown in FIG. 3 is inserted into the non-through hole 2 provided in the inorganic plate 1, and the side surface 33 of the spring body 31 of the snap ring 2 is the inner wall surface 22 of the non-through hole 2. Are in contact with each other in the circumferential direction.

(D) Fixing the snap ring to the skeleton, and (e) Fixing the inorganic plate to the skeleton In the embodiments shown in FIGS. This is done by fixing the end opposite to the end connected to the connecting portion of the connecting material to the skeleton. The connection of the connecting material to the connection portion of the snap ring may be made before or after the snap ring is inserted into the non-through hole. That is, a snap ring to which the connecting material is connected in advance may be prepared and inserted into the non-through hole, or the connecting material may be connected to the snap ring inserted into the non-through hole thereafter. The shape of the connecting material is not limited as long as it has the strength to lock the inorganic plate even when the first fixing means such as adhesion is lost as a result of the duplicated fixing means. For example, wire rods, tape-shaped steel materials and the like are preferably mentioned.

The means of connecting the snap ring to the connection portion is also not limited as long as the required strength is secured. For example, as shown in FIG. 8, when the snap ring of FIG. 3 is inserted into the non-through hole, the wire rod 41 is passed through the hole 35 of the connecting portion 32, the wire rod fixing member 42 is fixed to the wire rod, and the member 42. Cannot pass through the gap between the connecting portion 32 and the bottom surface 22 of the non-through hole 2, whereby the wire rod 41 is connected to the connecting portion 32.

Next, the end of the connecting material connected to the connecting portion of the snap ring as described above, which is opposite to the end connected to the snap ring, is fixed to the skeleton. FIG. 9 is an explanatory view of a state in which the inorganic plate 1 to which the snap ring to which the wire rod 41 is connected is locked, which is shown in FIG. 8, is fixed to the skeleton 51. In the figure, the wire rod 41 is fixed to a fixed point 61 by a fixture 5 driven into the skeleton 51 at an end opposite to the end connected to the snap ring. Subsequently, the inorganic plate 1 is attached to the surface 52 of the skeleton 51 with an adhesive. As described above, the inorganic plate 1 is fixed by two means, the fixing method according to the present invention and the sticking with an adhesive. Even if the inorganic plate 1 is not sufficiently fixed by an adhesive or the like due to deterioration over time, there is another fixing means using a snap ring according to the present invention, so that the inorganic plate 1 may fall off or be damaged due to the falling off. Can be prevented.

In the snap ring of the embodiment shown in FIGS. 5 and 6, the inorganic plate can be fixed to the skeleton by using the fixing hole 39 at the end 39 of the stretched portion 37 without using a connecting material such as a wire rod. Fixing can be performed by directly fixing this connecting portion to the skeleton with, for example, screws, tapping screws, anchor bolts, or the like.

FIG. 10 is an explanatory view of a state in which a plurality of inorganic plates 1 are attached to the surface 52 of the skeleton 51. In the figure, the inorganic plate 1 is fixed by fixing the wire rod 41 connected to the snap ring inserted in the non-through hole 2 to the fixed point 61. It is preferable that a plurality of non-through holes 2 are provided and fixed to one inorganic plate 1, and in FIG. 10, three non-through holes are provided and fixed to each inorganic plate. Further, the relationship between the wire rod and the fixed point is not only to suspend the wire rod from the fixed point, but also to provide the fixed point 62 laterally on the non-through hole 2 and to provide the wire rod 43, for example, as shown in FIG. The inorganic plate 1 may be lifted and fixed by pulling in the direction of the arrow in the figure. Further, in FIG. 10, the inorganic plate 1 is fixed in two stages, and the fixing point 61 for the inorganic plate in the lower stage is configured to be hidden by the inorganic plate in the upper stage. In FIG. 10, the fixing point 61 is provided above the upper end of the inorganic plate fixed by the fixing point 61, but is provided below the upper end, that is, at a position hidden by the inorganic plate fixed thereby. You may.

Although not particularly limited, it is preferable to use a fixture 5 such as a screw, a tapping screw, or an anchor bolt.

The adhesive is not limited as long as it can adhere an inorganic plate to the skeleton, but a synthetic polymer-based adhesive is preferable. As the synthetic polymer-based adhesive, an epoxy-based adhesive, a silicon-based adhesive, a urethane-based adhesive, an acrylic-based adhesive, or the like is preferably used. As these adhesives, any of adhesives that are liquid at room temperature (paste-like is included in liquid form), hot-melt adhesives, and tape-shaped adhesives can be preferably used.

In the present invention, the adhesion between the surface of the inorganic plate 1 having non-through holes and the skeleton 51 by an adhesive also includes an embodiment in which a base material is interposed between the inorganic plate 1 and the skeleton surface 52. do. In this case, for example, when the skeleton is a pillar such as a steel frame, a plate-shaped base material is fixed to the skeleton by a known method, and an inorganic plate is attached to the surface of the base material with an adhesive. Further, for example, when the method of the present invention is applied when remodeling an existing wall surface, an inorganic plate may be attached onto the existing wall surface using an adhesive as a base material. In either case, the screws and anchor bolts used for fixing are preferably fixed to the skeleton.
