Description

Technical Field

[0001] The present invention relates to a flat structure body in which rivets are attached to a flat plate body as an interior material or an exterior material attached to the wall surface (inner wall / outer wall) of the body of a structure such as a building or a non-structure such as a wall, and which is processed to prevent falling from the body, and a method for attaching the same.

Background Art

[0002] Conventionally, in buildings such as buildings, condominiums, schools, and hospitals, a tile construction method of pasting tiles on the wall surface of the body is performed for the functional advantage of protecting the structural body of the building and improving the design of the building. When pasting these tiles, it is common to take measures to prevent the tiles from peeling off or falling from the body.

[0003] On the other hand, in recent years, as tiles have become larger and thinner, a technique of riveting is used to bind the tiles and metal fittings with rivets and tightly fasten them to the body with stainless steel plates or stainless steel wires.

[0004] For example, in the tile structure described in Patent Document 1, there are a mandrel formed in a columnar shape with a head formed at the end, and a sleeve that fits on the outer circumference of the columnar portion of the mandrel and can be inserted into the concave portion of the tile. When the diameter of the sleeve inserted into the concave portion is enlarged by the head of the mandrel and the sleeve is compressed in the axial direction, a blind rivet in which the outer circumferential surface of the sleeve with the enlarged diameter is press-fitted to the inner circumferential surface of the concave portion and fixed to the inner circumferential surface of the concave portion by the press-contact force is disclosed.

[0005] In this tile structure, the mandrel is cut in the concave portion, and the head that has entered the sleeve remains.

Patent Document 1

[0007] In the blind rivet method described in Patent Document 1, the stress applied to the sleeve by the remaining head of the rivet that has entered the sleeve is directly applied to the recessed wall surface of the tile, which can lead to tile damage. In particular, the impact force when the mandrel is cut in the recess is transmitted more violently the larger the contact area with the recessed wall surface, which can also cause product defects in the tile structure.

[0008] To prevent tile damage, rivets made of soft materials such as aluminum can absorb applied stress and impact forces. However, aluminum is susceptible to corrosion from alkaline and acidic elements, and the presence of moisture can cause rust, resulting in undesirable wear resistance and corrosion resistance. In other words, aluminum is prone to galvanic corrosion, and deformation and wear of the aluminum are easily caused by the building's natural vibrations, traffic vibrations, wind, and earthquake vibrations. On the other hand, if special steels such as stainless steel, which are harder and less prone to rust than iron or aluminum, are used, the stress applied to the sleeve by the rivet head remaining inside the sleeve is directly applied to the recess of the tile, which is undesirable.

[0009] This invention has been made in view of the above problems, and its purpose is to provide a rivet with good wear resistance and corrosion resistance, and a new rivet method that is less likely to cause product defects in flat plate-shaped structures such as damage caused by rivets, and to provide a flat plate-shaped structure that can be attached to the wall surface of a building structure and a method for attaching the same. [Means for solving the problem]

[0010] To solve the above problems, the present invention provides the following.

[0011] (1) A flat plate-shaped structure that can be attached to the wall surface of a building structure and can be prevented from falling from the building structure using rivets, wherein the rivet comprises a rivet body having a hollow sleeve and a flange formed at one end of the sleeve, and a bottomed recess is formed on the back side of the flat plate-shaped tile, and the sleeve is embedded in the recess in a tapered shape that slopes from one end to the other.

[0012] According to the present invention, a bottomed recess is formed on the back side of the tile, and a rivet sleeve is embedded in the recess, thereby preventing the flat plate structure from falling off the frame by fastening a separate fastener with a rivet. The rivet is embedded in the recess with a sleeve that is angled outwards from one end to the other, and is fixed to the tile at the back of the sleeve, which widens in diameter as it widens within the recess. In other words, because the fastener is attached by a rivet, the present invention can prevent the tile from falling off the frame by fastening the tile to the wall surface of the frame with the fastener.

[0013] (2) A flat plate-like structure characterized in that the flared shape is formed by the action of a rivet having a mandrel which has a dish-shaped head 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.

[0014] According to the present invention, the rivet comprises a rivet body and a mandrel. The shaft portion of the mandrel, which is inserted through a hollow sleeve, is pulled out from inside the sleeve by the action of the rivet, so that only the rivet body is pressed against the tile and held in place, allowing the fastener to be attached. In other words, a rivet in which the mandrel does not remain inside the sleeve makes it less likely to cause product defects in flat plate-shaped structures due to breakage or the like.

[0015] (3) A flat plate-shaped structure characterized in that a fastener, which is held on the side of the tile that is attached to the frame, is attached to the tile by the rivet.

[0016] According to the present invention, the flat plate-shaped structure is prevented from falling from the structure by fastening the fixing device, which is held on the mounting surface side to the structure, with rivets.

[0017] (4) A flat plate-shaped structure characterized in that the rivet body is made of stainless steel.

[0018] According to the present invention, since the rivet body is made of stainless steel, it has good wear resistance and corrosion resistance.

[0019] (5) A method for attaching a flat plate-shaped structure to a wall surface of a building structure to prevent it from falling from the building 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, the method comprising: a first step of forming a bottomed recess on the back side of a flat plate-shaped tile; a second step of inserting the sleeve into the recess; and a third step of when the shaft portion is pulled out, the diameter of the sleeve is expanded in a tapered shape by the dish portion, sloping from one end to the other, and the expanded 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.

[0020] According to the present invention, a bottomed recess is formed on the back side of the tile, a rivet sleeve is embedded in the recess, and only the rivet body is pressed against the tile. The shaft of the mandrel, which is inserted through the hollow sleeve, is pulled out from inside the sleeve. As a result, a rivet is provided that does not leave a mandrel inside the sleeve, making it less likely to cause product defects in flat plate-shaped structures due to damage, etc.

[0021] (6) A method for attaching a flat plate-shaped structure, characterized in that, in the second step, the fastener held on the mounting surface side to the building structure is positioned in the recess, and then the sleeve is inserted into the recess to fix the fastener to the tile.

[0022] According to the present invention, after the step of fixing the fixture to the tile, by fixing the rivet in the third step, the rivet and the fixture can be fixed simultaneously, and a riveting method with good working efficiency can be provided.

Effect of the Invention

[0023] According to the flat plate structure of the present invention, there is an effect that a flat plate main body with a fall prevention measure can be easily processed and manufactured with good working efficiency and attached to the wall surface of the housing.

Brief Description of the Drawings

Best Mode for Carrying Out the Invention

[0025] Hereinafter, an example of a tile structure and an attachment method (construction method) according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The flat plate structure of the present invention includes tiles, stones, and others. Hereinafter, for example, tiles will be described. The material of the flat plate structure can be variously adopted, such as ceramics, stone, concrete, plastic, marble, etc. Further, the tile structure shown below is for processing tiles (flat plate main bodies) that cover the walls and floors of buildings, etc. The tiles are, for example, rectangular shapes such as 400 mm square, 600 mm square, 600 mm × 300 mm square, 1200 mm × 600 mm square, 1200 mm × 900 mm square, disc shapes, elliptical plate shapes, rhombic plate shapes, etc., and are also applicable to thin large plates with a thickness of about 6 mm.

[0026] Figure 1 is a perspective view of rivet 1, where 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 (mandrel 30 is not shown).

[0027] 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 so as to easily contact the open surface of the recess. For this reason, it is preferable that the open surface of the recess is also formed to match the outer surface 23 of the flange 22, which further strengthens the fastening force between the tile and the rivet body 20. The mandrel 30 has a dish portion (mandrel head) 31 at one end that 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.

[0028] 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 has expanded in diameter as the disc portion 31 of the mandrel 30 pushes out the sleeve 21 and passes through the hollow wall, resulting in a tapered shape with the hollow wall sloping from one end to the other. That is, the diameter of the sleeve 21 does not expand uniformly, but 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 one end and the other.

[0029] Figure 2 shows the installation process of a tile structure in which rivets 1 are attached to tiles 4.

[0030] (Step 1: 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 diameter of the hole is approximately the same as the diameter of the sleeve 21. The recess 41 is a round hole with a circular cross-section, including perfect circles and ellipses. By making the cross-section circular, damage caused by distortion applied to the tile 1 can be dispersed by the round hole, thus preventing damage to the tile 1 due to cracking. (Second step: Figure 2(b)) Recess 41 Insert the sleeve 21 into the recess. 41 The open surface and the outer surface 23 are brought into contact to position it. In this second step, the fastener 5, which is held on the mounting surface side to the building structure, is positioned in the recess 41, and then the sleeve 21 is inserted into the recess 41 to fix the fastener 5 to the tile 1 (see Figure 3). The fastener 5 is a stainless steel fastening fitting used to secure the tile 1 to the building structure and to the stainless steel wire 3 used to suspend the tile 1 from above and prevent it from falling, and is resistant to rust and corrosion. (Third step: Figure 2(c) → Figure 2(d)) The shaft portion 32 is completely withdrawn from the sleeve 21 so that the disc portion 31 does not remain inside the sleeve 21. At this time, the diameter of the sleeve 21 is widened by the disc portion 31, and the outer surface of the sleeve 21 with the widest diameter, located at the back of the recess 41, is pressed against the inner surface of the recess 41. This pressing force allows the rivet 1 to be fixed to the inner surface of the recess 41. Furthermore, the contact between the back of the recess 41 and the outer surface of the sleeve 21 absorbs the stress applied to the recess, making it less likely for the tile 4 to break.

[0031] Figure 3 shows an example of tiles being attached to a building structure. Pilot holes are drilled in the structure using a concrete drill, and screws made of precious metal (metal fittings) are inserted. The flat plate structure according to the present invention is bonded to the structure with adhesive mortar or elastic adhesive, and the tiles 4 and the structure are fastened together by wrapping SUS wire around the screws or fixing SUS plates to the screws using either fastener. The tiles and the structure are fastened together with fasteners such as stainless steel plates or stainless steel wires to prevent them from falling. In addition, the tiles and fasteners are fixed by rivet bodies 20. That is, the sleeve 21 of the rivet body 20 is embedded in the hole 41, and the fastener (SUS wire, SUS plate) is fixed by pressure contact between the flange 22 and the tile 4.

[0032] Conventionally, when fall prevention measures are implemented using an aluminum rivet body and stainless steel SUS wire, which are combinations of a precious metal and a base metal, the potential difference between stainless steel (precious metal) and aluminum (base metal) causes an electric current to flow, making galvanic corrosion likely to occur, which causes the base metal aluminum to corrode. However, since the rivet body 20 of the present invention is made of stainless steel, galvanic corrosion is less likely to occur. [Industrial applicability]
