Claims (6)

A flat plate-shaped structure that is attached to the wall surface of a building structure and can be prevented from falling from the structure using rivets, The rivet comprises a rivet body having a hollow sleeve and a flange formed at one end of the sleeve, A bottomed recess is formed on the back side of a flat , non-penetrating tile , and the sleeve is embedded in the recess in a tapered shape that slopes toward the bottom surface of the recess . The aforementioned flared shape is formed after the mandrel is withdrawn, and the disc portion of the mandrel does not remain inside the sleeve, characterized in that of a flat plate-like structure.
The flat plate-like structure according to claim 1, characterized in that the flared shape is formed by the action of the rivet, which comprises a mandrel having a dish-shaped head portion at one end having a diameter larger than the inner diameter of the sleeve, and a rod-shaped shaft portion having a diameter approximately the same as or smaller than the inner diameter of the sleeve and penetrating the hollow of the sleeve.
The flat plate-shaped structure according to claim 1 or 2, characterized in that a fastener, which is held on the mounting surface side to the building structure, is attached to the tile by the rivet.
The rivet body is made of stainless steel, as described in any one of claims 1 to 3.
A method for attaching a flat plate-shaped structure to a wall surface of a building structure to prevent it from falling from the structure, using a rivet comprising a hollow sleeve, a rivet body having a flange formed at one end of the sleeve, and a mandrel having a dish portion at one end that is larger in diameter than the inner diameter of the sleeve, and a rod-shaped shaft portion that is approximately the same diameter as or smaller in diameter as the inner diameter of the sleeve and penetrates the hollow of the sleeve, wherein the rivet is attached to the wall surface of a building structure to prevent it from falling from the structure, The first step is to form a bottomed recess on the back side of a tile , which is a flat, non-penetrating structure , A second step involves inserting the sleeve into the recess, In the third step, when the shaft is withdrawn, the diameter of the sleeve is widened by the disc portion, sloping toward the bottom surface of the recess , and the widened inner side of the sleeve is pressed against the inner circumferential surface of the recess, thereby fixing the rivet to the inner circumferential surface of the recess by the pressing force. A method for attaching a flat plate-shaped structure, characterized in that the flared shape is formed after the plate portion is pulled out, and the plate portion does not remain in the recess .
The method for attaching a flat plate-shaped structure according to claim 5, characterized in that, in the second step, the fastener held on the mounting surface side to the structure is positioned in the recess, and then the sleeve is inserted into the recess to fix the fastener to the tile.

Description

This invention relates to a flat plate structure and a method for attaching it to the wall surface (interior and exterior walls) of a structural frame (buildings, etc.) or non-structural frame (walls, etc.), using a flat plate body as an interior or exterior material, with rivets attached to prevent it from falling from the frame. Traditionally, tiling has been used in buildings such as office buildings, condominiums, schools, and hospitals to protect the structural framework and enhance the building's aesthetic appeal. It is common practice to take measures to prevent tiles from detaching or falling from the structure during this tiling process. On the other hand, in recent years, tiles have become larger and thinner, and riveting techniques are used to fasten tiles and metal fittings together, and then secure them to the structure using stainless steel plates or wires. For example, Patent Document 1 discloses a tile structure comprising a mandrel formed in a cylindrical shape with a head formed at its end, and a sleeve that fits onto the outer circumference of the cylindrical portion of the mandrel and can be inserted into a recess in the tile. The diameter of the sleeve inserted into the recess is expanded by the head of the mandrel, and the sleeve is compressed axially, causing the expanded outer surface of the sleeve to be pressed against the inner surface of the recess. A blind rivet is then attached to the inner surface of the recess, fixed by the pressing force. In this tile structure, the mandrel is cut in the recess, leaving the head that is inserted into the sleeve intact. Japanese Patent Publication No. 2015-10380 (Figures 1 and 4) A perspective view of a rivet used in an embodiment of the present invention.A diagram showing the construction process of a tile structure according to an embodiment of the present invention.A diagram showing an example of tile installation on the building structure. The following describes examples of tile structures and installation methods (construction methods) according to embodiments of the present invention, using Figures 1 to 3. While the flat structure of the present invention includes tiles, stone, and other materials, the following description will focus on tiles as an example. Various materials can be used for the flat structure, including ceramics, stone, concrete, plastic, and marble. Furthermore, the tile structure described below is for processing tiles (flat plates) to cover walls and floors of buildings, etc. These tiles can be rectangular in shape, such as 400mm x 400mm, 600mm x 600mm, 1200mm x 600mm, or 1200mm x 900mm, or in circular, elliptical, or rhomboid shapes, and can also be applied to thin, large plates with a thickness of approximately 6mm. Figure 1 is a perspective view of the rivet 1. Figure 1(a) shows the rivet body 20 and mandrel 30 integrated together, and Figure 1(b) shows the rivet body 20 with the mandrel 30 pulled out to the right of the paper (the mandrel 30 is not shown). As shown in Figure 1(a), the rivet 1 includes a skirt-shaped rivet body 20 and a slender, rod-shaped mandrel 30, which are combined and integrated. The rivet body 20 has a hollow, uniformly diameter sleeve 21, and a flange 22 formed at one end of the sleeve 21. The sleeve 21 side of the flange 22 has a dish-shaped or tapered outer surface 23, and a shallow type is preferable to facilitate contact with the open surface of the recess. Therefore, it is preferable that the open surface of the recess is also formed to conform to the outer surface 23 of the flange 22, thereby increasing the fastening force between the tile and the rivet body 20. The mandrel 30 has a dish-shaped portion (mandrel head) 31 at one end, which is larger in diameter than the inner diameter of the sleeve 21, and a rod-shaped shaft portion 32 that is approximately the same diameter as or smaller in diameter as the inner diameter of the sleeve 21 and penetrates the hollow of the sleeve 21. As shown in Figure 1(b), in the state where the mandrel 30 has been pulled out to the right in the plane of the paper, the rivet body 20 expands in diameter as the disc portion 31 of the mandrel 30 pushes outwards and passes through the hollow wall of the sleeve 21, resulting in a tapered shape where the hollow wall slopes from one end to the other. That is, the diameter of the sleeve 21 does not expand uniformly; the side where the disc portion 31 was located expands significantly. During the process of pulling out the mandrel 30, the outer circumference of the disc portion 31 conforms to the hollow wall of the sleeve 21, and the entire mandrel 30 is pulled out, resulting in a tapered shape at both ends. Figure 2 shows the installation process of a tile structure, where rivets 1 are attached to tiles 4. (First step: Figure 2(a)) A bottomed recess 41 is formed on the back side of the tile 4. The depth of the hole in the recess 41 is approximately the same length as or smaller than the sleeve 21, and the dia
