Description

[Technical Field]

[0001] The present invention relates to a base metal fitting, a panel for mounting a finishing material, a structure for mounting a finishing material, and a building. [Background technology]

[0002] Conventionally, a panel for attaching a finishing material as shown in FIG. 14 has been used to apply a finishing material (decorative panel) to a panel (metal, stone, ceramic, etc.) (see, for example, Patent Document 1). In this panel for attaching finishing material, a plate-shaped second base metal fitting 113 (receiving metal fitting) is attached to a panel 110 by a locking metal fitting 109, and a finishing material 131 is attached to the second base metal fitting 113 via a connecting member 130. The connecting member 130 is made up of a metal fitting 126 with a generally L-shaped cross section that is attached to the second base metal fitting 113 by welding or the like, and a plate-shaped metal fitting 122 that is connected to the metal fitting 126 by a bolt 123 and a nut 124.

[0003] The metal fitting 122 has a rod-shaped protrusion that protrudes vertically from the tip of a plate with a bolt insertion hole, and the protrusion fits into holes provided on the end surfaces of the upper finishing material 131 and the lower finishing material 131. The weight of the upper finishing material 131 is supported by the plate.

[0004] When ALC panels are used as panels for attaching finishing materials, as shown in Figure 15(a), the panels are attached to the building frame at two points, top and bottom, using panel mounting brackets 140. With this structure, in the event of an earthquake, the panels themselves will rock and absorb any inter-story displacement of the building frame (see Figure 15(b)).

[0005] The second base metal fitting 113 is attached to this panel using the various metal fittings described above, and then the finishing material 131 is attached. In the case of the second base metal fitting 113, in addition to being fixed to each panel with metal fittings in several places, metal fittings (connecting members) such as metal fitting 126 are required to attach the finishing material 131. Metal fitting 126 also serves as a ruler metal fitting (horizontal level guide) for directly attaching the finishing material 131. This metal fitting 126 (connecting member) needs to be attached to several panels in succession to keep the level constant (see Figure 16). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 6-185159 Summary of the Invention [Problem to be solved by the invention]

[0007] However, when finishing materials are applied to wall panels made of reinforced concrete (RC), the wall does not lock, but when finishing materials are applied to wall panels made of steel that have a locking mechanism, the finishing materials restrict the rocking of the wall panels, and seismic forces are applied to the wall panels and finishing materials.

[0008] As shown in Figure 16, when connecting members (metal fittings 126) that secure finishing materials are attached to adjacent panels 110, which have different rocking behaviors during an earthquake, either directly or via metal fittings, they not only restrict the rocking of each adjacent panel 110 during an earthquake, but also restrict the rocking of the finishing materials. In particular, the high binding and frictional forces that prevent rotation between the panels and finishing materials result in poor sliding, and excessive loads due to earthquake forces are placed on the panels, finishing materials, and the metal fittings that attach them. Furthermore, in conventional mounting structures, the shapes of the base metal fittings are limited, making them unsuitable for general use in terms of cost and ease of installation.

[0009] The present invention was proposed in consideration of the current situation, and its object is to provide a base fitting, a panel for mounting finishing materials, a finishing material mounting structure, and a building that do not hinder (restrain) the rocking of panels and finishing materials during an earthquake.

[0013] An embodiment of a furring fitting and a panel for attaching a finishing material according to the present invention will be described in detail below with reference to the drawings. Figures 1 to 5 show an embodiment of a furring fitting and a panel for attaching a finishing material according to the present invention.

[0014] First Embodiment In Figures 1 and 2, the panel 1 for mounting finishing material is a panel 10 to which base fittings 20 for mounting finishing material are attached, and a long hole 11 is drilled in a direction approximately perpendicular to the end face of the panel 10, and a countersunk hole 12 is drilled approximately perpendicularly from the surface so as to connect the surface of the panel 10 facing the finishing material 30 with the long hole 11 (see Figure 3). The panel 10 is attached to the framework of a building. The panel 10 is not particularly limited, and although a lightweight aerated concrete panel is shown here as an example, it can also be applied to inorganic panels commonly used as building panels, such as cement-based extrusion molding panels. The panel surface may be bare or painted.

[0015] A rod-shaped or tubular steel material 13 is inserted into the long hole 11 from the end face of the panel 10, and a locking metal fitting 14 is inserted into the countersunk hole 12 from the finishing material 30 side of the panel 10. Inside the panel 10, the steel material 13 and the locking metal fitting 14 are engaged with each other. 4, this locking fitting 14 is composed of an O-nut 15 (first nut) having an engagement hole 15a, a bolt 16 (first bolt), and a washer 17. The steel material 13 is engaged with the engagement hole 15a of the O-nut 15 inside the panel 10.

[0016] Figure 3 is a partial cross-sectional perspective view of Figure 1. To achieve the configuration shown in Figure 1, a long hole 11 is drilled in the end face of panel 10, approximately perpendicular to that face, and a countersink hole 12 is drilled from the outer surface of panel 10, extending perpendicular to this face, to connect the long hole 11 and the countersink hole 12. The long hole 11 and the countersink hole 12 can be easily drilled using a handheld electric drill commonly used at construction sites, but they can also be drilled in advance during the panel manufacturing process. Next, the locking hardware 14 is inserted into the long hole 11 through the countersink hole 12, with the engagement hole 15a of the O-nut 15 first. The steel material 13 is then inserted through the long hole 11 and attached so that it penetrates the engagement hole 15a. The O-nut 15 is long enough not to reach the outside of the countersink hole 12.

[0017] The diameter of engagement hole 15a of this O-nut 15 is approximately equal to the outer diameter of steel material 13, and when steel material 13 passes through engagement hole 15a, O-nut 15 and steel material 13 engage and become one piece. Steel material 13 can be passed horizontally through one panel 10 at multiple positions, for example, above and below, and locking fittings 14 can be attached in a line vertically (longitudinal direction of the panel) to secure first base fitting 21, and the number can be increased as needed. The O-nuts 15 may also be arranged and fixed by welding or other methods to the reinforcing bars inside the panel 10. In this case, the steel material 13 and the engagement holes 15a may be omitted. The O-nuts 15 are attached at positions approximately in the center of the panel 10's width, and are aligned longitudinally. Aligning the O-nuts 15 at approximately the center of the panel 10's width facilitates locking of the panel 10 and the finishing material 30, which is expected to provide even greater earthquake resistance. The spacing between the O-nuts 15 in the vertical direction (longitudinal direction of the panel) is preferably 600 mm or less. The pitch between adjacent base metal fittings 20 in the horizontal direction (width direction of the panel 10) is approximately equal to the width of the panel 10, or approximately an integer multiple of the width of the panel 10.

[0018] In this embodiment, the base metal fitting 20 is attached to the panel 10. In this embodiment, the base fitting 20 has at least a first base fitting 21 arranged on the surface of the panel 10 and a second base fitting 22 that fixes the finishing material 30, and has a locking mechanism between the first base fitting 21 and the second base fitting 22.

[0019] A flat first base metal fitting 21 and an L-shaped second base metal fitting 22 are arranged in this order on the O-nut 15 exposed on the surface of the panel 10. At this time, it is preferable to arrange a backup material 24 inside the panel 10, just before the elongated hole 11 of the countersink hole 12.

[0020] FIG. 5 is a perspective view showing the base metal fitting 20 (the first base metal fitting 21 and the second base metal fitting 22). The base metal fitting 20 has an O-nut 15 (first nut: not shown in FIG. 5) embedded in the panel 10 and a bolt 16 (first bolt) that screws into the O-nut 15, as well as a bolt portion 21b (second bolt) that is formed integrally with the first base metal fitting 21 and a nut 23 (second nut) that screws into the bolt portion 21b. The bolt portion 21b is disposed approximately parallel to the bolt 16 in a side view.

[0021] The first base metal fitting 21 is disposed on the surface of the panel 10. The first base metal fitting 21 has an insertion hole 21a through which the bolt 16 is inserted, and the first base metal fitting 21 is attached to the panel 10 by threading the O-nut 15 into the bolt 16 through the insertion hole 21a. The cross-sectional shape of the first base metal fitting 21 may be, for example, an L-shape, an I-shape, a U-shape, or a rectangular shape. The method of fixing the first base metal fitting 21 is not limited as long as it can be fixed to the panel 10. For example, the first base metal fitting 21 may be fixed to the panel 10 by passing a locking metal fitting such as a bolt fixed to the panel 10 through the insertion hole 21a, without using an O-nut 15. The first base metal fitting 21 may also be fixed directly to the panel 10 using a screw, a post-installed anchor, or the like.

[0022] The finishing material 30 is fixed directly or indirectly to the second furring fitting 22. The second furring fitting 22 has an insertion hole 22a through which the bolt portion 21b is inserted, and the second furring fitting 22 is attached to the first furring fitting 21 by threading the bolt portion 21b into a nut 23 through the insertion hole 22a. The second furring fitting 22 is rotatable within the plane of the first furring fitting 21, using the attachment axis to the first furring fitting 21 (the second attachment axis shown by the dotted line T in the figure), i.e., the bolt portion 21b, as the rotation axis.

[0023] When the first base metal fitting 21 is rotated on the surface of the panel 10, sliding is poor due to the large friction between the panel 10 and the first base metal fitting 21. Therefore, the second base metal fitting 22 is rotated preferentially on the surface of the first base metal fitting 21. Because the first base metal fitting 21 and the second base metal fitting 22 are in metal-to-metal contact, friction is reduced (allowing for good sliding), allowing the second base metal fitting 22 to rotate smoothly and improving locking performance. The first and second base metal fittings 21 and 22 are preferably made of metal, specifically, for example, SS material (general structural rolled steel) or stainless steel plate.

[0024] In particular, the finishing material mounting panel 1 of this embodiment is characterized in that the mounting axis S (first mounting axis, indicated by dotted line S in the figure) of the first furring fitting 21 to the panel 10 by the bolt 16 and the mounting axis T (second mounting axis) of the bolt portion 21b of the second furring fitting 22 are approximately parallel in side view. Furthermore, they are offset by a predetermined distance in a predetermined radial direction (vertical and / or horizontal) centered on the first or second mounting axis. This allows the fixed axis and the rotating axis to be separated, contributing to facilitating rotation and preventing loosening of the mounting portion (safety). The figure shows an example in which they are offset vertically. The predetermined distance is set to a degree that does not hinder the rotation of the second furring fitting 22.

[0025] By offsetting the mounting position (e.g., mounting axis S) of the first base metal fitting 21 from the mounting position (e.g., mounting axis T) of the second base metal fitting 22, the degree of fixation can be set and managed individually. That is, by offsetting the mounting positions (e.g., mounting axes), different tightening torques can be used. As described below, the first base metal fitting 21 can be firmly fixed and the second base metal fitting 22 can be loosely fixed to allow for rotation. (Note that if the same axis is used for rotation, a certain amount of rotational force will also be generated in the nut on the panel fixing side via the same bolt.) Therefore, in the event of an earthquake, the rotation of the first base metal fitting 21 and the second base metal fitting 22 will differ. For example, the rotation radius and rotation phase will differ. Furthermore, for example, the rotation of the first base metal fitting 21 and the rotation of the second base metal fitting 22 will cancel each other out, allowing for efficient deflection and more reliably preventing damage to the panel 10 and the finishing material 30. Furthermore, shifting the mounting position makes it easier to check the fastening points. During completion of construction inspections and maintenance, it is possible to visually check whether nuts 23 of first base metal fittings 21 are loose.

[0026] As shown in JP 2018-188850 A, when the first metal fitting (the metal fitting fixed to the panel) and the second metal fitting (the metal fitting that rotates) are fixed to the same axis, if the fixing force is too strong, the rotation of the second metal fitting will be restricted, and if the fixing force is too weak, the first metal fitting that should be fixed may rotate, making it difficult to set and manage the fixing force.

[0027] It is preferable that the tightening torque of the nut 23 that screws into the bolt portion 21b to attach the second base metal fitting 22 to the first base metal fitting 21 be equal to or smaller than the tightening torque of the bolt 16 that screws into the O-nut 15 to attach the first base metal fitting 21 to the panel 10. In the finishing material mounting panel 1 of this embodiment, a difference is made between the tightening torque of the first base metal fitting 21 and the tightening torque of the second base metal fitting 22. Specifically, by making the tightening torque of the nuts 23 that secure the second base metal fitting 22 to the first base metal fitting 21 smaller than the tightening torque of the bolts 16 that secure the first base metal fitting 21 to the panel 10, a rotation mechanism is formed that, during an earthquake, preferentially rotates between the first base metal fitting 21 and the second base metal fitting 22 rather than between the panel 10 and the first base metal fitting 21. This makes it possible to more efficiently absorb displacement caused by an earthquake. By preferentially rotating the second base metal fitting 22 on the first base metal fitting 21, the rotation of the first base metal fitting 21 on the surface of the panel 10 is kept small, preventing wear on the panel surface, such as peeling of the paint on the panel surface and scraping or damage to the panel base surface.

[0028] The tightening torque of the bolts 16 that secure the first base metal fitting 21 is preferably, for example, 20 to 25 N·m. The tightening torque of the nuts 23 that secure the second base metal fitting 22 is preferably, for example, 15 to 18 N·m. If the tightening torque is too small, the nuts may come loose, and if the tightening torque is too large, the bolts and nuts may be damaged.

[0029] It is preferable that the nut 23 that attaches the second base metal fitting 22 to the first base metal fitting 21 has an anti-loosening mechanism or is a double nut. The second base metal fitting 22 is usually attached to the first base metal fitting 21 using bolts and nuts. In this case, it is preferable to use nuts with an anti-loosening mechanism or to use double nuts. This makes it possible to prevent the nuts 23 from loosening when attaching the first base metal fitting 21, even if the tightening torque of the nuts 23 is relatively small. The mechanism for preventing the nut 23 from loosening is not particularly limited as long as it can achieve the purpose of preventing the nut 23 from loosening.

[0030] In this way, instead of attaching the second base metal fitting 22 directly to the panel 10, the second base metal fitting 22 is attached to the panel 10 via the first base metal fitting 21, and the tightening torque of the second base metal fitting 22 is set equal to or smaller than the tightening torque of the first base metal fitting 21. This allows the second base metal fitting 22 to rotate preferentially within the plane of the first base metal fitting 21 in response to the rocking of the panel 10 during an earthquake. This allows the connecting member 31 and finishing material 30 attached to the second base metal fitting 22 to also rock, making it possible to absorb displacement (see Figure 7). As a result, damage to the panel 10 and finishing material 30 caused by the application of excessive force can be avoided.

[0031] Furthermore, it is preferable that a sliding member be disposed between the first base metal fitting 21 and the second base metal fitting 22. Note that multiple sliding members may be used. This reduces the frictional force between the first base metal fitting 21 and the second base metal fitting 22, facilitating rotation. This prevents the rocking of the panel 10 and the finishing material 30 from being hindered (restricted) during an earthquake. The sliding material is not particularly limited as long as it can reduce the frictional force between the first base metal fitting 21 and the second base metal fitting 22, and an example of such a material is a stainless steel washer 25. The first base metal fitting 21 and the second base metal fitting 22 may be subjected to a surface treatment that reduces the coefficient of friction.

[0032] Next, the structure in which the finishing material 30 is attached to the panel 10 will be described with reference to Figures 6 and 7. In Figures 6 and 7, the finishing material 30 is attached to the second base metal fitting 22 of the panel 10 via a connecting member 31 (base rail). The cross-sectional shape of the second base metal fitting 22 is, for example, L-shaped, I-shaped, U-shaped, or rectangular. By using the above-described cross-sectional shape for the second base metal fitting 22, the connecting member 31 or the finishing material 30 can be fastened to the second base metal fitting 22 without interfering with the first base metal fitting 21 fastened to the panel 10 or the bolts that attach the first base metal fitting 21 to the panel 10.

[0033] The connecting member 31 is composed of, for example, a metal fitting with an L-shaped cross section that is attached to the second base metal fitting 22 by welding or with bolts and nuts. The connecting member 31 serves as a ruler metal fitting (horizontal level guide) for directly attaching the finishing material 30. This connecting member 31 needs to be attached continuously across several panels 10 to keep the level constant (see Figure 7). The finishing material 30 is attached to this connecting member 31. Various types of finishing material 30 (decorative board) can be used, such as cement-based, gypsum-based, metal-based, etc. The size of finishing material 30 is preferably about 0.6 m x 0.6 m to 1.2 m x 2.4 m or 0.6 m x 5 m.

[0034] As mentioned above, in the past, when connecting members (metal fittings 126) were attached to several panels 110 in succession, the panels themselves could be locked by inter-story displacement during an earthquake, but the base metal fittings and connecting members could not be locked (see Figure 16). Therefore, there was a risk that the panels 110 and finishing materials would be damaged by the application of excessive force.

[0035] In contrast, in the finishing material mounting structure of this embodiment, the second base metal fitting 22 is attached via the first base metal fitting 21. Therefore, even if the connecting member 31 is attached to several panels 10 in succession as shown in Figure 7, the second base metal fitting 22 will preferentially rotate in-plane on the first base metal fitting 21 in response to the rocking of the panel 10 during an earthquake, allowing the second base metal fitting 22 and connecting member 31 to lock while maintaining a horizontal position. The locking of the connecting member 31 allows the second base metal fitting 22, and therefore the connecting member 31 and finishing material 30 attached to the second base metal fitting 22, to absorb any displacement that occurs when the panel 10 rocks, preventing excessive force from being applied to the panel 10 and making them less susceptible to damage.

[0036] In addition, in the finishing material mounting structure of this embodiment, it is preferable to cut the edges of the connecting member 31, i.e., to divide the connecting member, at points where the wall is overhanging, such as points where it crosses over the opening reinforcement material and at corners where the wall is overhanging.

[0037] For example, as shown in circle A in Figure 8, by cutting the edge of the connecting member 31 at the boundary between the general wall portion and the opening (the point where it crosses the vertical material of the opening reinforcement material), the finishing material 30 will not hinder (restrain) the rocking of the panel 10 during an earthquake.

[0038] Furthermore, as shown in circle B in Figure 8, even in the case of a corner wall where the rocking behavior differs between the in-plane and out-of-plane directions, by cutting the edge of the connecting member 31, the finishing material 30 does not hinder (restrain) the rocking of the panel 10 during an earthquake.

[0039] In the above-described embodiment, an example was given in which the connecting member 31 was attached across several panels 10, but if the connecting member 31 is attached within one panel 10 rather than multiple panels 10, the first base metal fittings 21 may be attached at two or more locations within one panel 10, approximately parallel to one side of the panel 10 or approximately horizontally.

[0040] In the case of the above-described configuration, since the finishing material 30 has a primary waterproofing function, waterproofing treatment is not required for the underlying panel 10, and only when fire resistance is required can rock wool or glass wool be inserted into the horizontal joints to legally satisfy the requirement. If a secondary waterproofing function was required, sealant had to be poured into the vertical and horizontal joints of the panel 10, and the area around the metal fittings and nuts had to be sealed from the outside to prevent water leakage from the second base metal fittings 22 and nuts 23. The length of the sealant needed to be long to seal around the metal fittings, and both the top and bottom had to be sealed. There were also many bolts, making both areas a tedious job. Meanwhile, around the metal fittings, it was difficult to ensure the amount of sealing needed was only enough to cover the thickness of the metal fittings, and ensuring quality was also difficult. Furthermore, because the work was done from the outside, there were issues with ensuring long-term durability and compromising the aesthetics.

[0041] For this reason, for example, an amorphous sealing material 26 is press-fitted onto the surface of the countersink hole 12 in the panel 10, that is, between the backup material 24 and the first base metal fitting 21 (see FIG. 1).

[0042] However, if the watertightness is broken due to deterioration of the sealing or improper filling, there is a risk that the long hole 11 for the steel material 13 connected to the countersunk hole 12 of the O-nut 15 will become a waterway and cause water to leak into the room.

[0043] Therefore, in this embodiment, a sealant 27 (or putty) is filled into the long hole 11 at the edge of the panel 10 (see FIG. 1). By filling the slotted hole 11 for the steel material 13 with the sealing material 27 in addition to the countersunk hole 12, if the sealing of the countersunk hole 12 no longer functions to stop water leakage due to poor construction or the like, it is possible to ensure water leakage from the slotted hole 11 for the steel material 13 (the water outlet side). The sealing of the slotted hole 11 is performed, for example, in a factory. By providing double waterproofing in this way, the waterproofing of the finishing material fixing portion can be made more reliable.

[0044] The amorphous sealants 26, 27 are not particularly limited, and any wet sealant commonly used for sealing building materials can be used as appropriate, but preferred are modified silicone, acrylic urethane, polyurethane, and other sealants that are highly flexible and less likely to cause damage to the base material when deformed by external forces such as an earthquake. Specific examples include silicone, modified silicone, polysulfide, acrylic urethane, polyurethane, modified polysulfide, acrylic, SBR, butyl rubber, and polyisobutylene sealants specified in JIS A 5758:1997.

[0045] The softness of the sealants 26, 27 is not particularly limited, but they must be soft enough to be able to spread sufficiently throughout the holes and inside the nuts and fill gaps when pressed into place with the bolt 16 and first base metal fitting 21. If the sealants are too hard, they will be difficult to press into the holes, but conversely, if they are too soft and runny, they will sink due to gravity when pressed in and become unevenly distributed, making it impossible to fill the sealant evenly. The amount of sealing material 26, 27 to be filled is not particularly limited, but if it is too little, the gaps may not be filled sufficiently and waterproofing may not be ensured, and if it is too much, the excess sealing material will overflow and be wasted.

[0046] Furthermore, as a tertiary waterproofing function, sealant 28 may be filled in the joints that connect the panels 10 (see Figure 6). As shown in Figure 10, the joints may have a double-sealing configuration in which, from the exterior side, sealant 50, back-up material 51, sealant 50, and back-up material 52 are arranged in this order. A single-sealing configuration in which, from the exterior side, sealant 50 and back-up material 51 are arranged in this order is also possible, but double-sealing provides a higher level of waterproofing. This allows for a more complete waterproofing function. In the example shown in Figure 10, fire-resistant joint material 53 is filled on the interior side of back-up material 52.

[0047] The backup material is made of an elastically deformable material, and foamed polyethylene or foamed polystyrene is often used. Furthermore, when no external force is applied, the cross-sectional shape of the backup material is not limited, and examples include rectangular, trapezoidal, circular, semicircular, semi-elliptical, triangular, etc. In the example shown in Fig. 10, backup material 51 has a rectangular cross-sectional shape, and backup material 52 has a circular cross-sectional shape.

[0048] Also, a bond breaker may be used instead of the backup material 51. This can extend the life of the sealing material. The bond breaker must not adhere to the sealant, and paper, cloth, or plastic adhesive tape can be used.

[0049] In conventional structures, the metal fasteners (panel fasteners 40) used to secure the panel 10 to the building frame and the base metal fasteners (locking metal fasteners 14) used to attach the finishing material 30 to the panel 10 must be installed with a certain distance between them to avoid interference. Therefore, when multiple base metal fasteners are installed in the same direction along the length of the panel 10, the fixing positions for the finishing material 30 are located at a certain distance from the longitudinal ends (horizontal joints) of the panel 10 at the longitudinal ends of the panel 10, which results in a large distance from the horizontal joints of the panel 10 to the fixing positions for the finishing material 30 (x in Figure 6). This makes the longitudinal ends of the finishing material 30 prone to movement due to external forces such as wind loads.

[0050] Therefore, in this embodiment, as shown in Figure 9, the attachment direction of the base fittings 20 (first base fittings 21 and second base fittings 22) to the panel 10 is not all in the same direction, but is changed so that the fixing position of the finishing material 30 at the longitudinal end of the panel 10 is closer to the longitudinal end of the panel 10. At the longitudinal end (horizontal joint) of the panel 10, the mounting orientation of the first base metal fitting 21 and the second base metal fitting 22 is reversed from the conventional method, and the mounting positions of the base metal fittings 20 to the connecting members 31 are fixed so that they face the upper end (see Figure 9(a)) and lower end (see Figure 9(b)) of the panel 10, respectively. This makes it possible to reduce the distance from the horizontal joint of the panel 10 to the fixing position of the finishing material 30 (x1, x2 in Figure 9).

[0051] For example, a fastener for the base metal fitting is provided in a range of 100 mm or more away from the longitudinal end of the panel 10, and the side (horizontal part) of the second base metal fitting 22 that fixes the finishing material 30 is reversed from the conventional case and fixed toward (closer to) the longitudinal end of the panel 10. This allows the fixing position of the end of the finishing material 30 to be as close as possible to the horizontal joint of the panel 10. This also prevents the longitudinal end of the finishing material 30 from moving due to external forces such as wind load, allowing the end of the finishing material 30 to be stably fixed.

[0052] The present invention also includes a finishing material mounting structure in which a finishing material 30 (decorative panel) is attached to a finishing material mounting panel 1, and a building equipped with the finishing material mounting structure. The finishing material mounting structure and building of the present invention do not inhibit (restrain) the rocking of the panel and finishing material during an earthquake. This allows the structure to absorb inter-story displacement in the event of an earthquake and is less susceptible to damage.

[0053] Second Embodiment A second embodiment of the furring fitting and finishing material mounting panel of the present invention will be described in detail below with reference to the drawings. Figures 11 to 13 show the furring fitting of this embodiment, with (a) being a cross-sectional view and (b) being a top view. In the following description, differences from the first embodiment will be mainly described, and descriptions of similar parts will be omitted.

[0054] The base fitting of this embodiment is a base fitting consisting of multiple fittings for attaching finishing materials to a panel, and has a first base fitting 21 that is attached to the surface of the panel 10, and a second base fitting 22 to which the finishing material is attached directly or indirectly. In the base metal fitting 20 of this embodiment, the first base metal fitting 21 is attached to the panel 10 by an attachment axis S (first attachment axis), and the second base metal fitting 22 is attached to the first base metal fitting 21 by an attachment axis T (second attachment axis) coaxial with the attachment axis S, and is capable of rotatable in-plane on the first base metal fitting 21, and the attachment positions of the attachment axis S and the attachment axis T are separated in the out-of-plane direction.

[0055] Figure 11 shows the case where the cross-sectional shape of the first base metal fitting 21 of the base metal fitting of this embodiment is a square-shaped one, Figure 12 shows the case where the cross-sectional shape of the first base metal fitting 21 is a U-shaped one (vertical orientation), and Figure 13 shows the case where the cross-sectional shape of the first base metal fitting 21 is a U-shaped one (horizontal orientation).

[0056] In the first embodiment described above, the first base metal fitting 21 was generally flat, but by making the first base metal fitting 21 have a square or U-shaped cross section in this way, the second base metal fitting 22 can be attached to the first base metal fitting 21 with a mounting axis T that is coaxial with the mounting axis S. The mounting axes S and T are attached at different positions in the out-of-plane direction. In this way, in this embodiment as well, by shifting the mounting positions of the mounting axis S and the mounting axis T in the out-of-plane direction, it is possible to separate the fixed axis from the rotating axis, which contributes to promoting rotation and preventing loosening of the mounting portion (safety).

[0057] Furthermore, by offsetting the mounting position of the first base metal fitting 21 (e.g., mounting axis S) and the mounting position of the second base metal fitting 22 (e.g., mounting axis T) in the out-of-plane direction, the degree of fixation can be set and managed individually. Therefore, for example, by firmly fixing the first base metal fitting 21 and loosely fixing the second base metal fitting 22 to allow rotation, a difference in the rotation of the first base metal fitting 21 and the second base metal fitting 22 will occur during an earthquake. For example, the rotation radius and rotation phase will be different. Furthermore, for example, the rotation of the first base metal fitting 21 and the rotation of the second base metal fitting 22 will cancel each other out, allowing displacement to be efficiently absorbed and more reliably preventing damage to the panel 10 and the finishing material 30.

[0058] Although the embodiment of the present invention has been described above, the present invention is not limited to this and can be modified as appropriate within the scope of the invention. The present invention is not limited to indoor or outdoor use and is widely applicable to attaching finishing materials to panels. [Industrial Applicability]

[0059] By using the finishing material mounting panel of the present invention, it is possible to absorb inter-story displacement in the event of an earthquake and to make it less susceptible to damage, and it can be widely used as a finishing material mounting structure for buildings.
