Description

  The present invention relates to a method for fixing an inorganic plate, in particular, a thin and large ceramic plate to a wall or the like, and a fixing tool therefor, and more specifically, in addition to a fixing means for bonding the inorganic plate with an adhesive or the like. The present invention relates to a method for preventing exfoliation and the like, and a fixing tool therefor.

  Inorganic plates such as tiles are widely used as interior or exterior materials. These inorganic plates are fixed to the work surface by pasting them with an adhesive or mortar. Furthermore, recently, large ceramic plates that can reduce joints and simplify construction and diversify designs have been put into practical use and are widely used for such large ceramic plates. Tensioning with is common.

  When such an inorganic plate, especially a large ceramic plate, is applied to a wall surface or the like, even if peeling or cracking occurs over time, it is necessary to suppress peeling and damage due to peeling. Many large ceramic plates are thin and light in weight, but when a thin ceramic plate is used as an interior material in particular, a construction system capable of suppressing peeling and damage caused by peeling becomes important.

  As such a construction system, in addition to adhesion by an adhesive or the like, an inorganic plate is fixed to a construction surface using a fixture having a specific structure. For example, from a long mounting plate that is fixed in advance to a structural wall of a building, a plate-shaped mounting body that has an engaging portion that engages with a groove formed on the back surface of the tile, and a hook portion that is hooked on the mounting plate There is proposed a method of fixing a tile to a structural wall surface by hooking a tile fixture engaged with the tile onto a mounting plate using a fixture provided with a tile fixture (Japanese Utility Model Registration No. 3189682 (Patent) Document 1), Utility Model Registration No. 3189683 (Patent Document 2)). Since this fixture has a complicated shape of the tile fixture and has a structure in which the combination of the tile fixture and the fixture plate is arranged on the back surface of the tile, the distance between the tile and the structural wall increases. For this reason, the adhesive is applied in the form of dots or beads, and the gap between the tile and the structural wall increases. Therefore, it is considered that there is a limit in applying the mounting members described in these documents to the construction of a thin large-sized inorganic board where the thickness of the adhesive layer is preferably thin.

  Japanese Utility Model Registration No. 3203771 (Patent Document 3) relates to a fixed plate portion having a through hole and formed so as to be in contact with an inner wall or an outer wall of a building, and a slit formed on the back surface of the tile. And a locking plate portion formed so as to be in contact with the back surface of the tile, and the plane of the fixed plate portion and the plane of the locking plate portion are parallel to each other via the connecting portion. Arranged fixtures have been proposed. In this fixture, a space (clearance), preferably a clearance of 5 to 8 mm, is formed between the flat surface of the locking plate portion and the wall. Therefore, it is preferable that the adhesive layer is thin. In addition, there is a limit to the application of this fixture. Moreover, in the construction method using this fixing tool, the position which fixes the fixing tool in a wall surface is restrict | limited by the slit position of the tile back surface determined beforehand. In this case, to fix the tile more strongly to the wall surface, even if you try to apply this fixture to a groundwork such as a lightweight steel stud placed inside the wall, the fixture may not fit the position of the stud, The strength of tile fixing and the flexibility of tile assignment cannot be obtained.

  Therefore, it is highly applicable to inorganic plates, especially thin large-sized inorganic plates, or such inorganic plates can be assigned with a high degree of freedom, and damage due to such peeling and peeling of inorganic plates can be suppressed. There remains a need for construction methods and fixtures therefor.

Overview of the Invention FIG. 1 is an overview of the present invention as a whole. The present invention is a method of fixing the inorganic plate 2 to the work surface 3. In addition, the present invention is a fixture 1 used for fixing the inorganic plate 2 to the work surface 3. Furthermore, this invention is a structure provided with the to-be-processed surface 3 and the inorganic board 2 fixed to the to-be-processed surface 3. FIG. Hereinafter, after the definition is described, the fixing method, the fixture, and the structure according to the present invention will be described in detail.

Definition Inorganic board The inorganic board fixed to the construction surface described later by the fixing method according to the present invention or the fixing tool therefor is made of, for example, ceramic, stone, or glass. According to one aspect of 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 face materials, and counter finishing materials. Therefore, the inorganic board preferably includes a decorative surface on which a design is applied and a back surface that is attached to the surface to be processed. Further, although the size is not limited, the fixing method according to the present invention can be a double fixing method to the work surface of the inorganic plate, as will be described later. And is preferably applied to a large inorganic plate. According to one aspect of the present invention, the inorganic plate has a short side exceeding 300 mm and has an area exceeding 900 cm ² . The length of the short side of the inorganic plate is preferably 600 mm or more, more preferably 900 mm or more.

  Furthermore, the fixing method according to the present invention or a fixing tool therefor can be preferably applied to a relatively thin inorganic plate. When applied to a thin inorganic board, it is formed between the inorganic board and the work surface by an adhesive used for bonding, which is one of the double fixing methods of the inorganic board to the work surface described later. A thinner adhesive layer is preferred. In order to reduce the weight of a large ceramic plate, for example, the thickness is about 3 mm to about 15 mm, preferably about 10 mm, and more preferably about 8 mm.

  In the present invention, the inorganic plate may have a glaze layer on its surface. The ingredient of the glaze is not particularly limited. The glaze layer may be formed by either glazing after molding and firing integrally with the molded body, or by firing after glazing the calcined body (calcined body). Furthermore, you may provide a drying process before and after glazing.

Slit The inorganic plate to which the fixing method according to the present invention or a fixing tool therefor is applied has a slit on the back surface. The slit means a state in which a groove is formed by cutting, excavation, or molding obliquely from the back surface in the depth direction but does not reach the decorative surface.

  In the present invention, the slit of the inorganic plate means a groove, typically a groove having a predetermined length in the depth direction, but the shape of the slit when viewed from the back side is a rectangle or an ellipse. In addition, a non-through hole having a triangular shape or a polygonal shape may be formed in the depth direction so as to be understood as a slit. As long as the locking portion of the fixture described later can be inserted and locked, an arbitrary hole is included in the slit. For example, according to the aspect shown in FIG. 2, the slit 22 has a rectangular hole shape, and the slit 22 is formed with a predetermined inclination angle α from the back surface 21 of the inorganic plate 2 in the depth direction. FIG. 2A is a schematic view of the cross section of the slit 22 as viewed from the side surface of the inorganic plate 2, and FIG. 2B is a perspective view of the slit 22 as viewed from the back surface 21 of the inorganic plate 2.

  Considering the influence on the strength of the inorganic board, the depth of the slit should be about half or less of the thickness of the inorganic board in terms of the distance in the depth direction of the inorganic board, that is, the direction from the back surface to the decorative surface. Is desirable. The fixing method or the fixing device therefor according to the invention is advantageously used especially for relatively shallow slits in such thin inorganic plates. Specifically, for example, it is advantageously used for an inorganic plate having a slit depth of 1 mm to 5 mm. Further, the width of the slit (that is, the width when the direction along the strip is viewed in a vertical cross section) is not particularly limited as long as the locking portion of the fixture 1 can be inserted and locked. The angle α formed with the slit is preferably an acute angle. Thereby, the latching force of a latching | locking part increases by constructing the side which makes the angle | corner which a back surface and a slit make an acute angle upward. Further, the length of the slit (that is, the length in the direction along the stripe) is not particularly limited as long as the strength of the inorganic plate can be secured. Moreover, it is preferable that the end of the slit does not reach the end of the inorganic plate. In particular, since a thin and large inorganic plate is likely to be cracked starting from a slit, for example, as shown in FIG. 2B, the slit end is preferably separated from the end of the inorganic plate.

Surface to be constructed In the present invention, the surface of the exterior or interior wall, or the vertical surface or inclined surface of a building, on which the inorganic plate is fixed by the fixing method according to the present invention or a fixture therefor is referred to as “work surface”. That's it. In addition, a frame such as a column, a stud, a stud such as light gauge steel (LGS), a panel frame, or the like disposed inside the work surface is referred to as a “base”.

The fixing method by this invention The fixing method by this invention is a fixing method to the construction surface of an inorganic board using a fixing tool, Comprising: The said fixing tool is
A locking plate portion that can be locked to a slit formed on the back surface of the inorganic plate on one end side thereof, and a locking plate portion that can contact the back surface of the inorganic plate with the surface;
It is fixed to the construction surface, and comprises a fixed plate portion that can contact the construction surface with the surface,
The fixing plate portion is connected to the other end side of the locking plate portion opposite to the one end side where the locking portion is located, crossing the locking plate portion,
The surface on the opposite side of the surface of the locking plate portion that can be in contact with the back surface of the inorganic plate, and the fixed plate portion are on substantially the same surface,
The fixing method is
Preparing the inorganic plate having slits formed on the back surface;
Inserting the locking portion of the fixture into the slit and locking the inorganic plate with the locking plate portion; and
Bonding the inorganic plate locked by the locking plate portion to the construction surface;
A step of fixing the fixing plate portion of the fixture to the surface to be constructed.

  The fixing tool used in the fixing method according to the present invention will be described below.

The fixture according to the present invention is used to fix an inorganic plate, preferably a large inorganic plate, more preferably a thin large inorganic plate to a work surface, and includes a locking plate portion and a fixing plate portion. Prepare. FIG. 1 is a schematic view showing an embodiment of the present invention in which an inorganic plate is fixed to a work surface by a fixture. FIG. 3 is an enlarged side view of the embodiment shown in FIG. According to the embodiment shown in these drawings, the fixture 1 includes a locking plate portion 11 and a fixing plate portion 12, and the inorganic plate 2 is fixed to the work surface 3 by the fixture 1. According to a preferred aspect of the present invention, the fixture 1 is a metal fitting formed by processing a metal. The metal fitting has good strength and improves workability. Further, since the fixture 1 is a metal fitting, a good locking force with the inorganic plate 2 and a good fixing force with the work surface 3 are ensured.

The locking plate portion locking plate portion has a locking portion that can be locked to a slit formed on the back surface of the inorganic plate on one end side thereof. When the locking portion is locked by the slit, the inorganic plate is temporarily fixed by the fixture. Further, the locking plate portion is a plate-like material, preferably a plate formed by processing a metal plate. As a result, the locking plate portion can come into contact with the back surface of the inorganic plate on the surface, and a good locking force between the fixture and the inorganic plate can be secured. Moreover, since it is a plate-shaped object, a latching board part cannot change easily and has favorable intensity | strength. Furthermore, the work at the time of construction becomes easy. Further, the locking plate portion is configured such that a surface opposite to a surface that is in contact with the back surface of the inorganic plate is in contact with the surface to be processed. “Contact” means that the locking plate part is in direct contact with the work surface, and in fact the locking plate part and the work surface are isolated but close to each other, only through the fixed plate part. It is meant to include a mode of contacting, a mode of contacting only through the adhesive layer, or a mode of contacting through the fixing plate portion and the adhesive layer (without other intervening elements). When the locking plate portion is in contact with the work surface, the fixture can be accommodated between the inorganic plate and the work surface. According to one aspect of the present invention, referring to FIGS. 1 and 3, for example, the locking plate portion 11 has a locking portion 13 on one end side a thereof. The inorganic plate 2 is engaged with a slit 22 formed on the back surface 21. FIG. 4 is a perspective view of the locking plate portion 11. According to the embodiment shown in FIG. 4, the locking plate portion 11 has the locking portion 13 that can be locked to the slit 22 formed on the back surface 21 of the inorganic plate 2 on one end side a. Further, the locking plate portion 11 is in contact with the back surface 21 of the inorganic plate 2 on the surface in a region between the one end side a where the locking portion 13 is located and the other end side b on the opposite side. Further, the surface of the locking plate portion 11 opposite to the surface in contact with the back surface 21 of the inorganic plate 2 is in contact with the work surface 3 directly or via the adhesive layer 4.

The fixing plate portion fixing plate portion is connected to the other end side of the locking plate portion opposite to the one end side where the locking portion is located so as to cross the locking plate portion. Since the fixed plate portion is connected to the locking plate portion that locks the inorganic plate, the inorganic plate is fixed to the work surface by the fixture by fixing the fixed plate portion to the work surface. Here, the “other end side” means a position away from one end toward the opposite end. By connecting the fixed plate portions so as to cross at such positions, the inorganic plate can be arranged with a high degree of freedom without being affected by the structure of the base. The fixed plate portion is a plate-like material, and preferably a plate formed by processing a metal plate. Thereby, it becomes possible for the fixing plate part to come into contact with the construction surface, and to secure a good fixing force between the fixture and the construction surface. Moreover, since it is a plate-shaped object, a fixed plate part is hard to deform | transform and has favorable intensity | strength. Furthermore, the work at the time of construction becomes easy. According to one aspect of the present invention, for example, referring to FIG. 1 and FIG. 3, the fixing plate portion 12 is the opposite side of the locking plate portion 11 to the one end side a where the locking portion 13 is located. At the other end side b, it is connected to intersect with the locking plate portion 11. 5 and 6 are perspective views of the fixed plate portion 12. FIG. According to the embodiment shown in FIGS. 5 and 6, the fixed plate portion 12 is a plate-like object.

  According to a preferred aspect of the present invention, for example, as shown in FIGS. 1 and 6, the fixing plate portion 12 is the other end side b of the locking plate portion 11 opposite to the one end side a where the locking portion 13 is located. Further, it is connected to the locking plate portion 11 substantially orthogonally. “Substantially orthogonal” means a state in which the fixing plate portion 12 intersects the locking plate portion 11 at a substantially right angle with respect to the direction from the one end side a to the other end side b of the locking plate portion 11. To do. In this aspect, when the fixing plate portion 12 is disposed in the horizontal direction, the inorganic plate 2 and the locking plate portion 11 are disposed in substantially the same direction as the gravity direction. The stopping power can be increased.

  In the present invention, the locking plate portion 11 and the fixing plate portion 12 may integrally form the fixing device 1 (hereinafter also referred to as an integrated fixing device). Since both the locking plate portion 11 and the fixing plate portion 12 are plate-like objects, preferably metal plates, for example, the fixture 1 can be integrally formed. In addition, as will be described later, the locking plate portion 11 and the fixing plate portion 12 are separated, and the fixing device 1 may be configured in a state in which both are connected (hereinafter also referred to as a separate type fixing device). ).

  The fixture 1 according to the present invention will be described in more detail.

  FIG. 6 is a schematic diagram illustrating an example of a state in which the locking plate portion 11 and the fixed plate portion 12 are connected. If it demonstrates referring FIG. 6, in the fixing tool 1 by this invention, surface S2 on the opposite side to surface S1 of the latching plate part 11 which can contact | connect the back surface 21 of the inorganic board 2 in a surface. That is, the surface on the construction surface 3 side of the locking plate portion 11 and the fixing plate portion 12, specifically, the back surface S3 of the fixing plate portion 12, that is, the surface on the construction surface 3 side of the fixing plate portion 12, They are on the same plane. Thereby, both the locking plate portion 11 and the fixing plate portion 12 of the fixture 1 can come into contact with the surface 3 to be constructed. “On substantially the same surface” means that the locking plate portion 11 and the fixing plate portion 12 are on the same surface, that is, in a flush state, or the locking plate portion 11 and the fixing plate portion. Although 12 is not in a flush state, both the locking plate portion 11 and / or the fixing plate portion 12 are distorted (for example, with the force of the human power of the installer) to such an extent that the fixture 1 is not deformed. It means that it is in a state where it can be in contact with the same surface (that is, the construction surface 3). That the locking plate portion 11 (or the fixing plate portion 12) is in contact with the construction surface 3 in addition to the aspect in which the locking plate portion 11 (or the fixing plate portion 12) is in direct contact with the construction surface 3, Actually, the locking plate portion 11 (or the fixing plate portion 12) and the work surface 3 are separated but close to each other, and are in contact with each other only through the fixing plate portion 12 (or the locking plate portion 11). A mode of contacting only through the adhesive layer 4 or a mode of contacting through the fixing plate portion 12 (or the locking plate portion 11) and the adhesive layer 4 (without other intervening elements) is also included. Since the locking plate portion 11 and the fixing plate portion 12 are on substantially the same surface, the fixture 1 can be accommodated between the inorganic plate 2 and the work surface 3.

  In the construction system in which the inorganic plate 2 is fixed to the work surface 3 by using two means, that is, fixing by bonding using an adhesive and fixing by the fixture 1, the space between the inorganic plate 2 and the work surface 3 is fixed. It is desirable that the adhesive and the fixture 1 applied to each other do not interfere with each other's effects, and in particular, when fixing the thin large-sized inorganic plate 2, the amount of adhesive used is reduced to form the thin adhesive layer 4. It is preferable to do. In the fixture 1, the locking plate portion 11 and the fixing plate portion 12 are on substantially the same surface, and the degree of applicability to the thin large-sized inorganic plate 2 that fits between the inorganic plate 2 and the work surface 3 is particularly high. By using the high and thin fixing tool 1, it is stable and high between the inorganic plate 2 and the work surface 3 while exhibiting its own fixing force without inhibiting the adhesive force of the adhesive layer 4. Fixed strength can be secured.

According to a preferred aspect of the present invention, in the fixture 1 according to the present invention, the length of the fixing plate portion 12 is larger than the length of the locking plate portion 11. Thereby, it becomes possible to fix the inorganic board 2 to the to-be-processed surface 3 reliably. Moreover, it becomes possible to raise the freedom degree of allocation of the inorganic board 2, ie, the layout of the inorganic board 2 to the to-be-processed surface 3. FIG. Furthermore, it becomes possible to have the variability of the fixing position by the fixing tool 1. The length of the fixed plate portion 12 refers to the length of the fixed plate portion 12 in the longitudinal direction. More preferably, for example, in FIG. 1, the length in the horizontal direction when the fixed plate portion 12 is fixed to the construction surface 3. is refers to L _1, it is larger than the same direction of the length L ₂ of the engaging plate portion 11.

  According to the present invention, the fixture according to the present invention is used together with an adhesive to fix the inorganic plate to the work surface. As will be described later, the inorganic plate is adhered to the construction surface by applying the adhesive to the construction surface or the back surface of the inorganic plate, preferably the entire surface. With the adhesive layer made of this adhesive, the inorganic plate is fixed to the work surface by means of adhesion. At this time, the thickness of the portion excluding the locking portion of the fixing tool, that is, the portion of the fixing tool including the locking plate portion and the fixing plate portion excluding the locking portion may be smaller than the thickness of the adhesive layer. preferable. By making the thickness of the portion excluding the locking portion of the fixture smaller than the thickness of the adhesive layer after pasting, the fixture 1 can be accommodated between the inorganic plate 2 and the work surface 3. . In addition, by making the thickness of the portion excluding the locking portion of the fixture smaller than the thickness of the adhesive layer, another inorganic plate is attached so as to cover the fixture on the upper side of the inorganic plate fixed to the work surface. It can be pasted. In order to realize this, as described above, the locking plate portion of the fixture is a plate-like material obtained by processing a metal plate, and the locking plate portion can come into contact with the back surface of the inorganic plate on the surface, The locking force between the inorganic plate and the fixture is ensured. In addition, the fixing plate part of the fixing tool is also a plate-like material formed by processing a metal plate, so that the fixing plate part can come into contact with the work surface by a surface, and the fixing force between the work surface and the fixing tool is secured. Has been. Furthermore, by making the thickness of the portion excluding the locking portion of the fixture smaller than the thickness of the adhesive layer, the adhesive force of the adhesive layer is maintained well. That is, by using a thin fixture, adhesion by the adhesive is not hindered. According to one aspect of the present invention, for example, with reference to FIG. 3, the inorganic plate 2 is attached to the work surface 3 by the adhesive layer 4, and the locking portion 12 of the fixture 1 is excluded. The thickness T of the portion composed of the locking plate portion 11 and the fixed plate portion 12 is smaller than the thickness of the adhesive layer 4.

  The thickness of the adhesive layer 4 is preferably thin since the fixture 1 or the fixing method according to the present invention is particularly preferably applied to a thin large-sized inorganic board. The thickness of the adhesive layer 4 is, for example, not less than 0.5 mm and not more than 5 mm, preferably 1.3 to 1.7 mm.

  In the present invention, the thickness of the locking plate portion 11 of the fixture 1 is, for example, 0.1 to 1.5 mm. The thickness of the fixing plate portion 12 of the fixing tool 1 is, for example, 0.2 to 1.5 mm. The thickness T of the entire fixture 1 is, for example, 0.4 to 4.5 mm.

  The adhesive is not limited as long as the inorganic plate 2 can be bonded to the work surface 3, but a synthetic polymer adhesive is preferable. As the synthetic polymer adhesive, epoxy, silicon, urethane, acrylic and the like are preferably used. As these adhesives, any of a liquid or paste adhesive at normal temperature, a hot melt adhesive, and a tape-shaped adhesive can be suitably used.

  According to a preferred aspect of the present invention, the length of the fixed plate portion 12 is larger than the pitch of the base 5 such as a stud existing inside the work surface 3. Thereby, the fixing plate part 12 can be reliably fixed to the base 5. The length of the fixed plate portion 12 is more preferably an integer multiple of the pitch of the base 5. Thereby, the freedom degree of allocation of the inorganic board 2 is also raised, and workability improves.

  Thus, it is preferable that the fixed plate part 12 is a long plate-shaped object. Thereby, the fixing plate part 12 having a good strength can be reliably fixed to the base 5, and the fixing plate part 12 can be strongly fixed while being reliably in contact with the work surface 3. As a result, the inorganic plate 2 can be reliably fixed to the construction surface 3 via the fixture 1. Moreover, the freedom degree of allocation of the inorganic board 2 is raised, and workability improves.

  According to a preferred aspect of the present invention, the locking plate portion 11 and the fixed plate portion 12 are separate bodies. As a result, the locking plate portion 11 and the fixing plate portion 12 can be freely installed independently from each other on the work surface 3, and the locking plate portion 11 and the fixing plate portion 12 The positional relationship can be adjusted freely. For example, the fixing plate portion 12 is arranged at a predetermined position, for example, a position corresponding to the position of the base 5 such as a stud arranged inside the work surface 3, and the fixing plate portion 12 is later fixed with a screw or the like, Thereby, the fixed intensity | strength of the inorganic board 2 is securable. At the same time, the locking plate portion 11 is not limited to the position of the base 5 (no need to be matched), for example, can be freely moved in the length direction of the fixing plate portion 12, and any arbitrary fixing plate portion 12 can be moved. It can be connected to a desired position. Since the position of the locking plate portion 11 can be freely adjusted, the slit 22 can be formed at a desired position on the back surface 21 of the inorganic plate 2. For example, the slit 22 can be freely provided at a position where the strength of the inorganic plate 2 is stable, for example, at a position where the inorganic plate 2 is difficult to break. Thereby, pre-processing in a factory is attained and the quality of the inorganic board 2 is stabilized. As described above, by fixing the fixing plate 12 to the work surface 3 through fixing to the base 5, the inorganic plate 2 can be fixed while securing sufficient strength, and the locking plate 11 has sufficient strength. The high quality inorganic board 2 can be locked while ensuring. As a result, with the fixture 1 in which the locking plate portion 11 and the fixing plate portion 12 are separate, the inorganic plate 2 and the work surface 3 can be reliably fixed with a high degree of freedom. Since there is no need to fix the locking plate portion 11 that locks the inorganic plate 2 to the base 5, for example, according to the mode shown in FIGS. Without being limited thereto, the fixing plate 12 is locked to the work surface 3 by, for example, hitting the fixing component 14 against the base 5 by being locked by the slit 22 formed on the back surface 21 of the inorganic plate 2. Yes. Note that “connection” means a state in which the locking plate portion and the fixing plate portion are engaged or joined within a range in which the above-described effect is exhibited.

  According to a preferred aspect of the present invention, the fixing plate portion 12 is installed in the horizontal direction, and the locking plate portion 11 separate from the fixing plate portion 12 intersects the fixing plate portion 12 and is preferably Are connected at a right angle. For example, according to the mode shown in FIGS. 1 and 6, the locking plate portion 11 is folded back at the other end side b opposite to the one end side a where the locking portion 13 is located. 12 is inserted in the horizontal direction and both are connected. Or the folding | returning part U of the latching board part 11 may be hung on the fixed board part 12 installed in the horizontal direction, and both may be connected.

  In the present invention, as an example of connecting the locking plate portion 11 and the fixing plate portion 12, the locking plate portion 11 is connected to the fixing plate portion 12 at the other end opposite to the one end where the locking portion 13 is located. The aspect which further has the connection part which can connect the said latching board part 11 is mentioned. The connecting portion may be a member that can connect the locking plate portion 11 and the fixed plate portion, and the material and shape are not particularly limited as long as this is the case.

  According to a preferred aspect of the present invention, the fixing device 1 is a position where the locking plate portion 11 drives a plurality of fixing points, that is, fixing components 14 to be described later, in both the integrated fixing device and the separate fixing device. It is fixed with. Since the fixed plate portion 12 is long, the fixed component 14 is placed on both sides of the portion where the fixed plate portion 12 and the locking plate portion 11 are connected, in other words, on both sides of the portion to which both are connected. The position to be driven can be arranged. Thereby, the inorganic board 2 can be latched in several places, As a result, the latching force of the inorganic board 2 by the fixing tool 1 can further be heightened. In such an embodiment, the fixture 1 may include one fixing plate portion 12 and a plurality of locking plate portions 11. For example, according to the embodiment shown in FIG. 1, two locking plate portions 11 are connected to one fixed plate portion 12, and each locking plate portion 11 is engaged with a slit 22 formed on the back surface 21 of the inorganic plate 2. The upper end of the inorganic plate 2 is strongly locked by the fixture 1.

  According to a preferred aspect of the present invention, the locking plate portion 11 is, for example, a long fixing plate portion 12 arranged in the horizontal direction, regardless of whether the fixing device 1 is an integral type fixing device or a separate type fixing device. Are arranged side by side in the same direction (for example, the horizontal direction). With the plurality of locking plate portions 11 arranged side by side in the same direction, the inorganic plate 2 can be locked horizontally and stably. In addition, by disposing the locking plate portion 11 below the fixed plate portion 12, the inorganic plate 2 is locked so as to hang vertically below the fixed plate portion 12. Furthermore, in this aspect, since the fixed plate portion is fixed to the upper side of the inorganic plate, the other inorganic plate is stacked on the fixed plate portion using another fixing tool, and the inorganic plate Another inorganic plate can be fixed on the upper side of the plate. That is, since the fixture is hidden by the upper and lower inorganic plates and is not visually recognized from the outside, a beautiful layout can be obtained. For example, according to the aspect shown in FIG. 1, the two locking plate portions 11 are arranged below the fixed plate portion 12 in the same direction (horizontal direction). One inorganic plate 2 is locked to the lower side of the fixed plate portion 12 so as to hang in the vertical direction. Further, the upper inorganic plate 2 is fixed on the fixing plate portion 12 of the lower fixture 1 so as to overlap.

  According to one aspect of the present invention, since the inorganic plate 2 is large and heavy, for example, a desired portion of the inorganic plate 2, preferably between the lower end portion and the work surface 3, receives the load of the inorganic plate 2. A component 6 (for example, a metal fitting) may be disposed. Thereby, the load applied to the locking portion 13 of the fixture 1 is distributed to the load receiving component 6, and the inorganic plate 2 can be locked more reliably or stably. The thickness of the load receiving component 6 is, for example, 0.8 to 1.2 mm.

The fixing method according to the present invention will be described below step by step.
Step (i) of preparing an inorganic board
The fixing method by this invention includes the process (i) which prepares the inorganic board by which the slit was formed in the back surface. The slits are formed so that good locking between the locking portion of the fixture and the slit can be realized. The method is not particularly limited, and a known method is used. Although the slit may be formed at the construction site, it is desirable to form it in advance at the factory. Thereby, accuracy is ensured. According to one aspect of the present invention, for example, referring to FIGS. 1 and 3, an inorganic plate 2 having a slit 22 formed in advance on the back surface 21 is prepared.

Step (ii) of locking the locking plate portion of the fixture to the inorganic plate
The fixing method by this invention includes the process (ii) which inserts the latching | locking part of a fixing tool in a slit and latches a latching board part to an inorganic board. Accordingly, the locking plate portion comes into contact with the back surface of the inorganic plate on the surface, and the inorganic plate is temporarily fixed by the fixture. Temporary fixing is performed by means for increasing the locking force between the fixture and the inorganic plate by bringing the slit width closer to the thickness of the locking portion, so that the front and back surfaces of the locking portion are in contact with the upper and lower surfaces inside the slit. Alternatively, it can be performed with a tape or an adhesive. When it is sufficiently temporarily fixed by this step, the process may move to the next step. According to one aspect of the present invention, for example, with reference to FIGS. 1 and 3, the locking portion 13 of the fixture 1 is locked to the slit 22. Thereby, the inorganic board 2 will be in the state temporarily fixed by the fixing tool 1. FIG. In the present specification, the term “temporarily fixed” is used as a paired word when the fixing of the inorganic plate by the fixture 1 described later is referred to as “mainly fixed”, and the inorganic plate 2 As long as is locked by the fixture 1, it does not mean the strength of the locking force. In other words, after the step (ii) is performed, when the locking force is weakened for some reason, even when the locking force is recovered thereafter, the step (ii) is performed at that time. It is not understood.

The process of bonding the inorganic board to the work surface (iii)
The fixing method by this invention includes the process (iii) of adhere | attaching the inorganic board latched by the latching board part to a to-be-processed surface. Adhesion is performed using, for example, an adhesive. The adhesive is applied to the back surface or the work surface of the inorganic plate, and preferably applied to the entire surface. Moreover, it is preferable to apply so that the usage-amount of an adhesive agent may not increase, and to form a thin adhesive layer. Thereby, a strong adhesive force can be obtained. In the step (iii), the inorganic plate is fixed to the work surface by means of adhesion. According to one aspect of the present invention, for example, referring to FIGS. 1 and 3, the inorganic plate 2 is attached to the work surface 3 to which an adhesive has been applied in advance. In addition, it is preferable to apply | coat an adhesive agent to the whole surface of a to-be-processed surface. For example, in on-site construction, a paste-like adhesive is applied to the back surface of the inorganic board or the work surface using a comb eyelid.

A step (iv) of fixing a fixing plate portion of the fixture to the construction surface;
The fixing method according to the present invention includes a step (iv) of fixing a fixing tool, specifically, a fixing plate portion of the fixing tool to a work surface. According to one aspect of the present invention, for example, as shown in FIGS. 1 and 3, the fixing plate portion 12 of the fixture 1 protruding from the upper end of the inorganic plate 2 is disposed inside the work surface 3. It is fixed to the base 5 such as LGS. For fixing the fixed plate portion 12 to the base 5, known means and methods can be used. For example, the fixed component 14 is driven into the fixed plate portion 12. As a result, the fixed plate portion 12 can come into contact with the work surface 3 through fixing to the base 5, and the fixed plate portion 12 and the work surface 3 are firmly fixed. By the step (iV), the inorganic plate 2 is fixed to the construction surface 3 by the fixing means by the fixing tool 1. According to the fixing method of the present invention, the inorganic plate 2 is fixed to the work surface 3 by two means of fixing by adhesion in the step (iii) and fixing by the step (iv). Even when the adhesive force becomes insufficient due to deterioration over time or the like, there is a fixing means using a fixing tool, so that peeling and damage due to peeling can be prevented. That is, according to the present invention, there is provided a double fixing method of the inorganic plate to the work surface. The fixing component 14 is not particularly limited as long as it has a strength capable of fixing the inorganic plate even when the first fixing means that is bonded is lost as a double fixing means as a result. , Tapping screws, drilling screws, nails, rivets and the like. The shape of the head of the fixed component 14 may be appropriately determined in consideration of the thickness T of the entire fixture 1, and is not particularly limited, but a shape that does not become uneven, such as a low head shape, is preferable.

  The fixing method according to the present invention includes the steps (i) to (iv). The step (i) of preparing the inorganic plate and the step (ii) of locking the inorganic plate to the fixture are performed in this order. In the fixing method according to the present invention, the inorganic plate bonding step (iii) and the inorganic plate fixing step (iv) may be performed in this order (hereinafter referred to as Embodiment 1), and the fixing step (iv). And the bonding step (iii) may be performed in this order (hereinafter referred to as Embodiment 2). It should be noted that a mode in which the steps (i) and (ii) are shipped from the improvement in a state where the steps (i) and (ii) are performed in advance and the steps (iii) and (iv) are performed on-site is also included in the present invention.

A step (i) of preparing an inorganic plate 2 having a slit 22 formed on its back surface 21;
Inserting the locking portion 13 of the fixture 1 into the slit 22 and locking the inorganic plate 2 with the locking plate portion 11 (ii);
A step (iv) of fixing the fixing plate portion 12 of the fixture 1 to the construction surface 3;
A step (iii) of adhering the inorganic plate 2 locked by the locking plate portion 11 to the work surface 3 in this order.

  In Embodiment 2, since the step (iv) of fixing the fixing plate portion to the work surface and the step (iii) of bonding the inorganic plate to the work surface are performed in this order, the application of the adhesive is a step. It is preferable to carry out in advance before (iv). The second embodiment can be employed in the construction where the ground unevenness adjustment and the slit position accuracy are high.

  The fixing method according to the present invention will be described again. In addition, unless specifically described as Embodiments 1 and 2 below, the fixing method is described as including both of these, regardless of whether they are different.

  According to a preferred aspect of the present invention, the fixing method according to the present invention is a step of confirming that the inorganic plate 2 is locked by the fixing tool 1, specifically, the locking portion 13 of the locking plate portion 11. Further included. The locking state of the inorganic plate 2 by the fixture 1 can be easily confirmed by moving the fixture 1 relatively above the inorganic plate. For example, by pulling a predetermined portion of the fixture 1 protruding from the upper end of the inorganic plate 2 upward, for example, and confirming that the fixture 1 has no play, that is, tension is applied, the fixture 1 It can be easily confirmed that is securely locked to the inorganic plate 2, that is, that the temporary fixing of the inorganic plate 2 by the fixture 1 is securely performed. In addition, the operation of moving the fixture 1 to check the locking state of the inorganic plate 2 corrects this loosening even if the locking force is loosened at the stage of construction prior to the checking operation, for example. In addition, there is an advantage that the locking force is strengthened (recovered). As a result, a highly safe construction system can be provided. The predetermined portion for moving the fixture 1 is not particularly limited as long as it is a portion that protrudes from the upper end of the inorganic plate 2 in the fixture 1 and can be gripped by the installer. For example, when the fixed plate portion 12 or the locking plate portion 11 protrudes, the fixed plate portion 12 or the locking plate portion 11 may be moved. The inorganic plate 2 is subjected to the step (iii) and / or the step (iv) at a position where the fixing device 1 is moved and the play is lost in the fixing device 1, that is, a position where the tension is applied.

  According to a preferred aspect of the present invention, the step of confirming that the inorganic plate 2 is locked by the fixing tool 1 is performed by inserting the locking portion 13 of the fixing tool 1 into the slit 22 and the locking plate portion 11. In the step (ii) of locking the inorganic plate 2, it is performed after the step (ii), and according to a more preferable embodiment, the step is performed before the step (iv) of fixing the inorganic plate 2 to the work surface 3. Thereby, prior to the step (iv) of fixing or permanently fixing the inorganic plate 2 to the work surface 3, it can be confirmed that the inorganic plate 2 is locked by the fixture 1 without any problem by the step (ii). The subsequent steps (iii) and (iv) can be performed safely. In addition, the confirmation operation itself for moving the fixture also results in the enhancement of the locking force. Alternatively, when it is determined that the locking force needs to be strengthened by the confirmation work, the locking force may be strengthened using this as a trigger. Before fixing the inorganic plate 2 to the work surface 3, it is very important from the viewpoint of safety to confirm that the inorganic plate 2 is securely locked by the fixture 1. The realization of the means that can be implemented in the future is strongly demanded at the construction site. According to the present invention, it is possible to easily and surely confirm the locked state only by moving the fixture 1 without using a special instrument or the like for the confirmation work or performing a special method. can do.

In the case where the fixing method according to the present invention includes the step of confirming the locking of the inorganic plate, whether the fixing tool is an integral-type fixing tool or a separate-type fixing tool, in the first embodiment, the checking process is related to It may be carried out between the stopping step (ii) and the bonding step (iii) (hereinafter referred to as Embodiment 1-1). That is, the method of Embodiment 1-1 is

A step (iii) of bonding the inorganic plate 2 locked by the locking plate portion 11 to the construction surface 3;
A step (iv) of fixing the fixing plate portion 12 of the fixture 1 to the work surface 3 in this order.

In the first embodiment, the confirmation step may be performed between the bonding step (iii) and the fixing step (iv) (hereinafter referred to as embodiment 1-2). That is, the method of Embodiment 1-2 is
A step (i) of preparing an inorganic plate 2 having a slit 22 formed on its back surface 21;
Inserting the locking portion 13 of the fixture 1 into the slit 22 and locking the inorganic plate 2 with the locking plate portion 11 (ii);
A step (iii) of bonding the inorganic plate 2 locked by the locking plate portion 11 to the construction surface 3;
A step of moving the fixture 1 to confirm that the inorganic plate 2 is locked by the locking plate portion 11;
A step (iv) of fixing the fixing plate portion 12 of the fixture 1 to the work surface 3 in this order.

When the fixing method according to the present invention includes an inorganic plate locking confirmation step, in the second embodiment, the confirmation step may be performed between the locking step (ii) and the fixing step (iv) (hereinafter referred to as the fixing step (iv)). Embodiment 2-1). That is, the method of Embodiment 2-1 is:
A step (i) of preparing an inorganic plate 2 having a slit 22 formed on its back surface 21;
Inserting the locking portion 13 of the fixture 1 into the slit 22 and locking the inorganic plate 2 with the locking plate portion 11 (ii);
A step of moving the fixture 1 to confirm that the inorganic plate 2 is locked by the locking plate portion 11;
A step (iv) of fixing the fixing plate portion 12 of the fixture 1 to the construction surface 3;
A step (iii) of adhering the inorganic plate 2 locked by the locking plate portion 11 to the work surface 3 in this order.

When the fixing method according to the present invention includes an inorganic plate locking confirmation step, in the second embodiment, the confirmation step may be performed between the fixing step (iv) and the bonding step (iii) (hereinafter, referred to as “fixing step”). Embodiment 2-2). That is, the method of Embodiment 2-2 is
A step (i) of preparing an inorganic plate 2 having a slit 22 formed on its back surface 21;
Inserting the locking portion 13 of the fixture 1 into the slit 22 and locking the inorganic plate 2 with the locking plate portion 11 (ii);
A step (iv) of fixing the fixing plate portion 12 of the fixture 1 to the construction surface 3;
A step of moving the fixture 1 to confirm that the inorganic plate 2 is locked by the locking plate portion 11;
A step (iii) of adhering the inorganic plate 2 locked by the locking plate portion 11 to the work surface 3 in this order.

  In the case where the slit is formed at the site, Embodiment 1-2 in which the locking state is likely to be weak and the workability is relatively excellent is preferable. In particular, the embodiment performed immediately before the step (iv) of fixing the confirmation step is that the fixing can be performed while applying tension to the fixture, and it is possible to work substantially as one step. ,preferable.

  In the present invention, for example, as shown in FIG. 7, the fixture 1 confirms the locking state of the inorganic plate 2 by the locking portion 13 at a predetermined portion of the fixture 1 protruding from the upper end of the inorganic plate 2. You may have further the knob part which makes it possible. The knob part should just be provided in the part in which a builder is easy to hold | grip, and the arrangement | positioning in particular is not restrict | limited. For example, it is provided in a desired portion of the fixed plate portion 12 or the locking plate portion 11. Even if it is difficult to grip the fixture due to the structure or construction state of the fixture, the confirmation operation can be easily performed by having the knob portion. The confirmation of the locked state may be performed in the same manner as in the case of using a fixture. Easily confirm that the inorganic board is securely locked to the locking part of the locking plate part by moving the knob part and confirming that there is no play in the knob part, that is, that tension is applied. can do. According to a preferred aspect of the present invention, the knob portion 15 is provided on the locking plate portion 11 as shown in FIGS. Since the inorganic plate 2 is locked to the locking plate portion 11, it is possible to confirm the locked state more directly by providing the locking plate portion 11 with the knob portion 15. More preferably, the knob portion 15 is provided on the other end side b of the locking plate portion 11 opposite to the one end side a where the locking portion 13 is located. The shape of the knob portion 15 is not particularly limited as long as it is a shape that can move the fixture 1. Examples of the shape of the knob portion 15 include an annular shape, a T-shape, and an S-shape. The material of the knob part 15 is not particularly limited as long as the knob part 15 has a strength that does not break due to the weight of the inorganic plate when the knob part is moved and the play is lost. The operation of confirming the locking by the knob portion 15 may be performed at the same timing as the step of confirming the locking by the fixing tool.

  According to a preferred aspect of the present invention, the portion of the fixing device 1 excluding the locking portion 13, that is, the portion of the fixing device 1 including the fixing plate portion 12 and a portion other than the locking portion 13 of the locking plate portion 11. Is smaller than the thickness of the adhesive layer 4 after the fixing plate portion 12 of the fixture 1 is fixed to the work surface 3. That is, the thickness T of the fixture 1 (excluding the locking portion 13) is preferably smaller than the thickness of the adhesive layer 4 and thin to some extent. When the inorganic plate 2, particularly a thin large inorganic plate is securely fixed to the work surface 3, it is preferable to form the adhesive layer 4 having a small thickness in the bonding using an adhesive or the like as described above. By using the thin fixture 1 that matches such a thin adhesive layer 4, there is no possibility that the adhesive force by the adhesive is hindered by the presence of the fixture 1.

  According to a preferred aspect of the present invention, the locking plate portion 11 and the fixed plate portion 12 are separate bodies. Thereby, in Embodiment 1, for example, the operation of locking the inorganic plate 2 by the locking plate portion 11 and the operation of fixing the fixing plate portion 12 to the surface to be processed 3, the inorganic plate 2 being the surface to be processed in the meantime. 3 can be performed independently, including the work of bonding to 3. That is, it is possible to independently adjust the locking position of the locking plate portion 11 to the inorganic plate 2 and the fixing position of the fixing plate portion 12 to the base 5, and further, the fixing position and the locking position can be adjusted. The relative positional relationship can be freely adjusted. Specifically, the slit 22 can be formed at a desired position where the strength is stable in the inorganic plate 2, and in other words, independent of the locking plate portion 11 that locks the inorganic plate 2, in other words, the inorganic material Without being restricted by the position of the plate 2 or the locking plate portion 11, the fixing plate portion 12 can be freely arranged and fixed at a position where it can be fixed to the base 5. As a result, the inorganic plate 2 can be locked while securing sufficient strength by the locking plate portion 11, and sufficient strength can be obtained by fixing the fixing plate portion 12 to the work surface 3 through fixing to the base 5. As a result, the inorganic plate 2 can be fixed while securing the fixing of the inorganic plate 2 and the work surface 3 with the fixture 1.

  Conventionally, in order to secure the fixing strength of the inorganic plate, for example, the fixture must be fixed at the position of the base, and in this case, the inorganic plate is engaged by being limited to the position of the locking portion of the fixture. In some cases, the slits cannot be formed at desired positions on the inorganic plate. For this reason, a slit could not be formed in advance at a desired position of the inorganic plate at the factory, and it had to be handled on site. As a result, the strength of the inorganic plate may not be ensured.

  For example, in the first embodiment, when the locking plate portion 11 and the fixing plate portion 12 are separate bodies, the step (iv) of fixing the fixing plate portion to the construction surface is the step of bonding the inorganic plate to the construction surface ( Since it is after iii), the positioning of the fixed plate portion becomes easy. For example, as shown in FIGS. 1 and 3, the fixing plate portion of the fixing device 1 is connected to the folded portion U of the locking plate portion 11 of the fixing device 1 protruding from the upper end of the inorganic plate 2 attached to the work surface 3. 12 is sandwiched horizontally. As a result, the fixed plate portion 12 is connected substantially orthogonally to the locking plate portion 11 that locks the inorganic plate 2 bonded to the work surface 3. The fixing plate portion 12 is arranged at a position suitable for fixing to the base 5 such as LGS arranged inside the work surface 3. The fixing plate 12 is fixed to the base 5 as described above. The folded portion U of the fixture 1 may be formed on site, but it is desirable to form it in advance at the factory. Thereby, accuracy is ensured.

  For example, in Embodiment 1-2, when the locking plate part 11 and the fixing plate part 12 are separate bodies, that is, when the fixing tool is a separate fixing tool, for example, the engagement protruding from the upper end of the inorganic board 2 The fixed plate portion 12 sandwiched between the folded portions U of the stop plate portion 11 is pulled upward so that the locking plate portion 11 is securely locked to the inorganic plate 2, that is, the inorganic plate by the locking plate portion 11. Confirm that the temporary fixing of 2 has been made securely. Then, the fixing plate portion 12 is fixed to the base 5 with a fixing component at a position where there is no play in the locking plate portion 11, that is, at a position where tension is applied to the locking plate portion 11. Therefore, when fixing the inorganic plate to the work surface, by confirming that the inorganic plate is securely locked by the locking plate portion, fixing that has already been performed and fixing that is performed thereafter Double fixing to the work surface of the inorganic plate by two means of fixing by the tool can be carried out reliably.

  According to one aspect of the present invention, between the step of locking the inorganic plate with the locking plate portion of the fixture and the step of attaching the inorganic plate to the work surface, for example, the lower end portion of the inorganic plate and the cover Between the construction surface 3, a part (for example, a metal fitting) 6 for receiving the load of the inorganic plate 2 may be constructed. Thereby, when the 1st fixing force by adhesion | attachment weakens and an inorganic board peels, it can disperse | distribute that a load concentrates on a slit, and can prevent a failure | damage. Furthermore, depending on the case, since the upper part of the inorganic plate locked by the fixture is lifted to the front side of the work surface, that is, the inorganic plate is inclined, the separation can be visually recognized, so that repair can be started promptly. In addition, when the latching plate part 11 of the fixture 1 overlaps with the position of the load receiving component 6, the load receiving component is preferably post-installed.

This structure has the freedom of construction such as the assignment of the inorganic plate 2 without complicating the structure of the fixture 1, the locking force between the fixture 1 and the inorganic plate 2, the fixture 1 and the work to be performed. It can be obtained by realizing a construction system that is excellent in fixing force with the surface 3 and as a result has excellent fixing force between the inorganic plate 2 and the work surface 3.

It is small.

Moreover, according to the preferable aspect of this invention, in the structure of this invention, a fixing tool is fixed to a to-be-processed surface with a fixing component, and this fixing component does not exist in a position lower than a latching | locking part. It is characterized by that. According to a more preferred aspect of the present invention, the connection position between the fixed plate portion and the locking plate portion does not exist at a position lower than the locking portion. Thereby, even if the adhesive force of the adhesive is reduced, it is possible to reliably obtain a locking force that does not drop the inorganic plate from the construction stage.
