Description

Technical Field

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

Background Art

[0002] Conventionally, in order to finish a panel with a finishing material (decorative board) (such as metal pasting, stone pasting, ceramic board pasting, etc.), a panel for attaching a finishing material as shown in FIG. 14 has been used (for example, Patent Document 1). In this panel for attaching a finishing material, a plate-shaped second base fitting 113 (receiving fitting) is attached to a panel 110 by a locking fitting 109, and a finishing material 131 is attached to the second base fitting 113 via a connecting member 130. The connecting member 130 is composed of an L-shaped metal fitting 126 having a substantially L-shaped cross section attached to the second base fitting 113 by welding or the like, and a plate-shaped metal fitting 122 coupled to the metal fitting 126 by bolts 123 and nuts 124.

[0003] The metal fitting 122 is provided with a rod-shaped protrusion protruding in the vertical direction at the tip of a plate having bolt insertion holes, and the protrusion is fitted into holes provided in the end faces of the upper finishing material 131 and the lower finishing material 131, respectively. The weight of the upper finishing material 131 is supported by the plate.

[0004] When assuming an ALC panel as the panel for attaching a finishing material, as shown in FIG. 15(a), the upper and lower parts of the panel are attached to a building frame at two points using panel attachment fittings 140. With this structure, when an earthquake occurs, the inter-story displacement of the building frame is diverted by the panel itself locking (see FIG. 15(b)).

[0005] The second base fitting 113 is attached to this panel using the various types of fittings described above, and then the finishing material 131 is attached. In the case of the second base fitting 113, after being fixed to one panel with several fittings, a fitting (connecting member) such as the fitting 126 for attaching the finishing material 131 is required. Further, the fitting 126 serves as a straightedge fitting (horizontal level guide) for directly attaching the finishing material 131. In order to keep the level of this fitting 126 (connecting member) constant, it is necessary to attach it continuously to several panels (see Fig. 16).

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, when providing a finishing material to a wall panel made of RC (reinforced concrete), the wall does not rock. However, when providing a finishing material to a wall panel made of steel frame and having a locking mechanism, the finishing material restrains the locking of the wall panel, and seismic forces are applied to the wall panel and the finishing material.

[0008] As shown in Fig. 16, when a connecting member (fitting 126) for fixing the finishing material is attached to the panel directly or via a fitting across adjacent panels 110 having different locking behaviors during an earthquake, it not only restrains the locking of each adjacent panel 110 during an earthquake, but also restrains the locking of the finishing material. In particular, due to the high restraining force and frictional force against the rotation between the panel and the finishing material and the poor slipperiness, excessive loads due to seismic forces are applied to the panel, the finishing material, and each fitting for attaching them. In addition, in the conventional attachment structure, since the shape of the base fitting is limited, it has no versatility in terms of cost and constructability.

[0009] The present invention has been proposed in view of such a conventional situation, and an object of the present invention is to provide a base fitting, a panel for attaching a finishing material, a finishing material attachment structure, and a building that do not inhibit (restrain) the locking of the panel and the finishing material during an earthquake.

Embodiments for Carrying Out the Invention

[0013] Hereinafter, an embodiment of a base fitting and a panel for attaching a finishing material of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 5 are views showing an embodiment of a base fitting and a panel for attaching a finishing material of the present invention.

[0014] <First Embodiment> In FIGS. 1 and 2, the panel 1 for attaching a finishing material is a panel for attaching a finishing material in which a base fitting 20 for attaching a finishing material is attached to a panel 10. A long hole 11 is drilled in a direction substantially perpendicular to the end face from the end face of the panel 10, and a counterbore 12 is drilled substantially perpendicular to the surface so as to communicate the surface of the panel 10 on the side of the finishing material 30 and the long hole 11 (see FIG. 3). Panel 10 is attached to the building structure. The panel 10 is not particularly limited, and here, a lightweight cellular concrete panel is shown as an example, but it can also be applied to inorganic panels generally used as building panels, such as cement extrusion panels. Also, the panel surface may be either the base material 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 fitting 14 is inserted into the counterbore 12 from the side of the finishing material 30 of the panel 10. Inside the panel 10, the steel material 13 and the locking fitting 14 are engaged. 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 as shown in FIG. 4. The steel material 13 is engaged with the engagement hole 15a of the O-nut 15 inside the panel 10.

[0016] FIG. 3 is a partial cross-sectional perspective view of FIG. 1. To achieve the configuration as shown in FIG. 1, a long hole 11 is drilled in the end face of the panel 10 in a direction substantially perpendicular to the face, and a counterbore 12 reaching this face at a right angle is drilled from the outer surface of the panel 10 to communicate. The long hole 11 and the counterbore 12 can be easily drilled with a hand-held electric drill commonly used at the construction site, but it is also possible to drill them in advance during the panel manufacturing process. Next, the engagement hole 15a of the O-nut 15 of the locking fitting 14 is inserted into the long hole 11 with the engagement hole 15a facing forward from the counterbore 12, and the steel material 13 is inserted from the long hole 11 and attached so as to penetrate the engagement hole 15a. The O-nut 15 is made to have a length that does not reach the outside of the counterbore 12.

[0017] The diameter of the engagement hole 15a of this O-nut 15 is approximately equal to the outer diameter of the steel material 13. By the steel material 13 penetrating the engagement hole 15a, the O-nut 15 and the steel material 13 are engaged and integrated. The steel material 13 can be horizontally passed through a panel 10, for example, at a plurality of upper and lower positions respectively, and the locking fittings 14 can be arranged vertically (in the panel longitudinal direction) and attached to fix the first base fitting 21, and can be increased as needed. The O-nut 15 may also be arranged and fixed by means such as welding to the reinforcing bars inside the panel 10. In that case, the steel material 13 and the engagement holes 15a can also be omitted. Note that the mounting positions of the O-nuts 15 (and thus the mounting positions of the base brackets 20) are arranged side by side in the longitudinal direction at approximately the center in the width direction of the panel 10. When the mounting positions of the O-nuts 15 are arranged substantially at the width center of the panel 10, it becomes easier to lock both the panel 10 and the finishing material 30, so a further seismic resistance effect can be expected. The interval in the vertical direction (panel longitudinal direction) of the O-nuts 15 is preferably, for example, 600 mm pitch or less. Also, the pitch of the adjacent base brackets 20 in the lateral direction (width direction of the panel 10) is made substantially equal to the width dimension of the panel 10 or an approximate integral multiple of the width dimension of the panel 10.

[0018] And in this embodiment, the base bracket 20 is attached to the panel 10. In this embodiment, the base bracket 20 has at least a first base bracket 21 arranged on the surface of the panel 10 and a second base bracket 22 for fixing the finishing material 30, and has a mechanism for locking between the first base bracket 21 and the second base bracket 22.

[0019] The flat plate-shaped first base bracket 21 and the L-shaped second base bracket 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 the backup material 24 inside the panel 10, in front of the long hole 11 of the counterbore hole 12.

[0020] FIG. 5 is a perspective view showing the base bracket 20 (the first base bracket 21 and the second base bracket 22) extracted. The base bracket 20 has the O-nut 15 (the first nut: omitted in FIG. 5) embedded in the panel 10 and the bolt 16 (the first bolt) screwed with the O-nut 15, and the bolt portion 21b (the second bolt) provided integrally with the first base bracket 21 and the nut 23 (the second nut) screwed with the bolt portion 21b. The bolt portion 21b is arranged substantially parallel to the bolt 16 in a side view.

[0021] The first base fitting 21 is disposed on the surface of the panel 10. The first base fitting 21 has an insertion hole 21a through which the bolt 16 is inserted. By screwing the O-nut 15 and the bolt 16 through the insertion hole 21a, the first base fitting 21 is attached to the panel 10. The cross-sectional shape of the first base fitting 21 is, for example, an L-shape, an I-shape, a U-shape, or a C-shape. Note that as long as the first base fitting 21 is fixed to the panel 10, the fixing method is not limited. For example, the first base fitting 21 may be fixed to the panel 10 by passing a locking fitting such as a bolt fixed to the panel 10 through the insertion hole 21a without using the O-nut 15. Alternatively, the first base fitting 21 may be directly fixed to the panel 10 with screws, post-installation anchors, or the like.

[0022] The second base fitting 22 is fixed directly or indirectly to the finish material 30. The second base fitting 22 has an insertion hole 22a through which the bolt portion 21b is inserted. By screwing the bolt portion 21b and the nut 23 through the insertion hole 22a, the second base fitting 22 is attached to the first base fitting 21. The second base fitting 22 is rotatable in the plane on the first base fitting 21 with the attachment axis to the first base fitting 21 (the second attachment axis indicated by the dotted line T in the figure), that is, the bolt portion 21b, as the rotation axis.

[0023] When the first base fitting 21 is rotated on the surface of the panel 10, the frictional force between the panel 10 and the first base fitting 21 is large, so it is difficult to slide. Therefore, the second base fitting 22 is preferentially rotated on the surface of the first base fitting 21. Since the first base fitting 21 and the second base fitting 22 are in contact with each other as metals, the frictional force is reduced (it becomes easy to slide), and the second base fitting 22 can be rotated well, improving the locking performance. The first base fitting 21 and the second base fitting 22 are preferably made of metal. Specifically, for example, they are made of an SS material (rolled steel for general structures) or a stainless steel plate.

[0024] And particularly in the panel 1 for attaching the finishing material of the present embodiment, the mounting axis S (the first mounting axis shown by the dotted line S in the figure) of the first base fitting 21 to the panel 10 by the bolt 16 and the mounting axis T (the second mounting axis) of the bolt portion 21b of the second base fitting 22 are substantially parallel in a side view. Further, they are at positions shifted by a predetermined interval in a predetermined radial direction (vertical direction and / or horizontal direction) centered on the first or second mounting axis. Thereby, it is possible to separate the axis for fixing and the axis for rotation, which contributes to the promotion of rotation and the prevention of loosening (safety) of the mounting portion. In the figure, the case where they are shifted in the vertical direction is shown as an example. The predetermined interval is set to such an extent that it does not inhibit the rotation of the second base fitting 22.

[0025] Since the mounting position (for example, the mounting axis S) of the first base fitting 21 and the mounting position (for example, the mounting axis T) of the second base fitting 22 are shifted, the fixing degree can be individually set and managed. That is, by shifting the mounting position (for example, the mounting axis), the tightening torque can be properly used. As will be described later, the first base fitting 21 can be firmly fixed, and the second base fitting 22 can be loosely fixed for rotation (when they are on the same axis, a rotational force is generated in the nut on the panel fixing side through at least the same bolt). Therefore, during an earthquake, a difference occurs between the rotation of the first base fitting 21 and the rotation of the second base fitting 22. For example, the rotation radius and the rotation phase are different. And, for example, by the rotation of the first base fitting 21 and the rotation of the second base fitting 22 canceling each other out, the displacement can be efficiently received, and it is possible to more surely avoid the panel 10 and the finishing material 30 from being damaged. Also, by shifting the mounting position, the confirmation of the fixed portion becomes simple. During the construction completion inspection and maintenance, it is possible to visually confirm whether the nut 23 of the first base fitting 21 is loose.

[0026] As disclosed in Japanese Patent Application Laid-Open No. 2018-188850, when the first fitting (the fitting fixed to the panel) and the second fitting (the fitting to be rotated) are fixed to the same axis, if the fixing force is strong, the rotation of the second fitting is restricted, and if the fixing force is weak, the first fitting to be fixed may rotate, and it is difficult to set and manage the fixing force.

[0027] The tightening torque of the nut 23 that engages with the bolt portion 21b for attaching the second base fitting 22 to the first base fitting 21 is preferably equal to or smaller than the tightening torque of the bolt 16 that engages with the O-nut 15 for attaching the first base fitting 21 to the panel 10. In the panel 1 for attaching the finishing material of the present embodiment, a difference is provided between the tightening torque of the first base fitting 21 and the tightening torque of the second base fitting 22. Specifically, by making the tightening torque of the nut 23 that fixes the second base fitting 22 to the first base fitting 21 smaller than the tightening torque of the bolt 16 that fixes the first base fitting 21 to the panel 10, a rotation mechanism that preferentially rotates between the first base fitting 21 and the second base fitting 22 is formed during an earthquake, rather than between the panel 10 and the first base fitting 21. Thereby, the displacement due to the earthquake can be more efficiently dissipated. By preferentially rotating the second base fitting 22 on the first base fitting 21, the rotation of the first base fitting 21 on the surface of the panel 10 can be suppressed to a small extent, and wear on the panel surface, for example, peeling of the paint on the panel surface, shaving and damage to the surface of the panel substrate can be prevented.

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

[0029] The nut 23 for attaching the second base fitting 22 to the first base fitting 21 preferably has a locking mechanism or is a double nut. The attachment of the second base fitting 22 to the first base fitting 21 usually uses bolts and nuts. At this time, it is preferable to use a nut having a locking mechanism or a double nut. Thereby, even if the tightening torque of the nut 23 is relatively small in the attachment of the first base fitting 21, loosening of the nut 23 can be prevented. The locking mechanism of the nut 23 is not particularly limited as long as it can achieve the purpose of locking.

[0030] In this way, instead of directly attaching the second base fitting 22 onto the panel 10, the second base fitting 22 is attached to the panel 10 via the first base fitting 21, and the tightening torque of the second base fitting 22 is made equal to or smaller than the tightening torque of the first base fitting 21. Then, during an earthquake, in response to the rocking of the panel 10, the second base fitting 22 preferentially rotates within the plane of the first base fitting 21. Thereby, the connecting member 31 and the finishing member 30 attached to the second base fitting 22 can also rock and are able to receive the displacement (see Fig. 7). As a result, it is possible to avoid damage to the panel 10 and the finishing member 30 caused by the application of excessive force.

[0031] Furthermore, it is preferable that a sliding material is arranged between the first base fitting 21 and the second base fitting 22. Note that the number of sliding materials may be plural. Thereby, the frictional force between the first base fitting 21 and the second base fitting 22 can be reduced, and rotation can be promoted. Thereby, the rocking of the panel 10 and the finishing member 30 during an earthquake is not inhibited (restrained). The sliding material is not particularly limited as long as it can reduce the frictional force between the first base fitting 21 and the second base fitting 22. For example, a stainless steel washer 25 can be mentioned. The first base fitting 21 and the second base fitting 22 may be subjected to a surface treatment with a low 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 FIGS. 6 and 7. In FIGS. 6 and 7, the finishing material 30 is attached to the second base fitting 22 of the panel 10 via a connecting member 31 (base rail). The cross-sectional shape of the second base fitting 22 is, for example, an L-shape, an I-shape, a U-shape, or a C-shape. Since the second base fitting 22 has the above cross-sectional shape, the connecting member 31 or the finishing material 30 can be fixed to the second base fitting 22 without interfering with the first base fitting 21 fixed to the panel 10 and bolts for attaching the first base fitting 21 to the panel 10.

[0033] The connecting member 31 is composed of, for example, a metal fitting having an L-shaped cross-section attached to the second base fitting 22 by welding, bolts and nuts, etc. The connecting member 31 serves as a straightedge fitting (horizontal level guide) for directly attaching the finishing material 30. In order to keep its level constant, this connecting member 31 needs to be continuously attached over several panels 10 (see FIG. 7). The finishing material 30 is attached to this connecting member 31. As the finishing material 30 (decorative panel), various types such as cement-based, gypsum-based, and metal-based can be used. Also, the size of the finishing material 30 is appropriately, for example, about 0.6 m × 0.6 m to 1.2 m × 2.4 m or 0.6 m × 5 m.

[0034] As described above, conventionally, when the connecting member (metal fitting 126) was continuously attached to several panels 110, even if the panel itself could rock due to inter-story displacement in the event of an earthquake, the base fitting and the connecting member could not rock (see FIG. 16). Therefore, there was a risk that the panel 110 and the finishing material would be damaged due to an excessive force being applied.

[0035] On the other hand, in the finishing material attachment structure of the present embodiment, since the second base metal fitting 22 is attached via the first base metal fitting 21, as shown in FIG. 7, even when the connecting member 31 is continuously attached to several panels 10, in the event of an earthquake, the second base metal fitting 22 preferentially rotates in the plane on the first base metal fitting 21 in response to the rocking of the panel 10, so that the second base metal fitting 22 and the connecting member 31 can also rock while maintaining horizontal. By the connecting member 31 rocking, the displacement when the panel 10 rocks can be received by the second base metal fitting 22, and thus the connecting member 31 and the finishing material 30 attached to the second base metal fitting 22, and the panel 10 and the finishing material 30 are less likely to be damaged without being subjected to excessive force.

[0036] In addition, in the finishing material attachment structure of the present embodiment, at locations where the wall wins or loses, such as locations straddling the opening reinforcement member and the protruding corner, it is preferable to cut the edge of the connecting member 31, that is, divide the connecting member.

[0037] For example, as shown by circle A in FIG. 8, by cutting the edge of the connecting member 31 at the boundary between the general wall portion and the opening (the location straddling the vertical member of the opening reinforcement member), the rocking of the panel 10 during an earthquake is not obstructed (restrained) by the finishing material 30.

[0038] Also, as shown by circle B in FIG. 8, even in the winning and losing walls at the protruding corner where the rocking behavior is different in the in-plane direction and the out-of-plane direction, by cutting the edge of the connecting member 31, the rocking of the panel 10 during an earthquake is not obstructed (restrained) by the finishing material 30.

[0039] In the above-described embodiment, the case where the connecting member 31 is attached across several panels 10 has been described as an example. However, when the connecting member 31 is attached within one panel 10 instead of a plurality of panels 10, the first base metal fitting 21 may be attached at two or more locations within one panel 10 substantially parallel to one side of the panel 10 or in a substantially horizontal direction.

[0040] By the way, in the case of the configuration as described above, since the finishing material 30 has a primary waterproof function, the panel 10 as the base does not require waterproof treatment, and legally it is satisfied only when fire resistance performance is required by inserting rock wool or glass wool into the horizontal joints. When a secondary waterproof function is required, a sealing material is placed at the vertical and horizontal joints of the panel 10, and in order to prevent water leakage from the second base metal fitting 22 and the nut 23 parts, it is necessary to seal around the metal fittings and nuts from the outside. Sealing around the metal fittings has a long sealing length, and it is necessary to perform the sealing treatment without forgetting both the top and bottom. Also, there are many locations around the bolts, and both are complicated operations. On the other hand, it is difficult to secure a sealing margin only by the thickness of the metal fitting around the metal fitting, and it is also difficult to ensure its quality. Furthermore, since it is a construction from the outside, there are problems of ensuring long-term durability and impairing aesthetics.

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

[0042] However, when the water stop fails due to deterioration or poor filling of the seal, there is a risk that the long hole 11 for the steel material 13 connected to the counterbore 12 of the O-nut 15 will become a water passage and leak water to the indoor side.

[0043] Therefore, in this embodiment, the long hole 11 at the bottom edge of the panel 10 is filled with a sealing material 27 (or putty material) (see FIG. 1). In addition to the counterbore 12, by filling the long hole 11 for the steel material 13 with the sealing material 27, when the sealing of the counterbore 12 fails to function due to poor construction or the like, the water stop performance can also be ensured from the long hole 11 for the steel material 13 (the water outlet side). The sealing of the long hole 11 is performed, for example, at the factory. By making the double water stop in this way, the water stop performance of the finishing material fixing part can be made more reliable.

[0044] The amorphous sealing materials 26 and 27 are not particularly limited, and wet sealing materials commonly used for sealing building materials can be appropriately used. For example, sealing materials such as modified silicon-based, acrylic urethane-based, and polyurethane-based, which are rich in flexibility and less likely to cause the destruction of the base material when deformed by external forces such as earthquakes, are preferred. Specific examples include those specified in JIS A 5758:1997, such as silicon-based, modified silicon-based, polysulfide-based, acrylic urethane-based, polyurethane-based, modified polysulfide-based, acrylic-based, SBR-based, butyl rubber-based, and polyisobutylene-based materials.

[0045] The softness of the sealing materials 26 and 27 is not particularly limited, but it is necessary to have a softness that can be sufficiently spread into the holes and inside the nuts by press-fitting with the bolt 16 and the first base metal fitting 21 to fill the gaps. If it is hard, it is difficult to press-fit it into the inside of the hole. Conversely, if it is too soft and in a loose state, it will sag and deviate due to gravity during press-fitting, and the sealing material cannot be filled uniformly. The filling amount of the sealing materials 26 and 27 is not particularly limited, but if it is too little, there is a risk that the gaps cannot be filled sufficiently and the waterproof property cannot be ensured. If it is too much, the excess sealing material will overflow to the outside and be wasted.

[0046] Furthermore, as a third waterproof function, the joint 28 may be filled with a sealing material at the joint between the panels 10 (see Fig. 6). As the configuration of the joint, as further shown in Fig. 10, a double-sealing configuration including a sealing material 50, a backup material 51, a sealing material 50, and a backup material 52 in order from the outdoor side can be mentioned. In addition, a single-sealing configuration including a sealing material 50 and a backup material 51 in order from the outdoor side can also be mentioned, but the double-sealing has higher water-stopping performance. Thereby, the water-stopping function can be made more perfect. In the example shown in Fig. 10, a fireproof joint material 53 is filled on the indoor side of the backup material 52.

[0047] The backup material is made of an elastically deformable material, and foamed polyethylene and foamed polystyrene are often used. Also, in a state where no external force is applied, the cross-sectional shape of the backup material is not limited, and examples include shapes such as a rectangle, a trapezoid, a circle, a semi-circle, a semi-ellipse, and a triangle. In the example shown in FIG. 10, the backup material 51 has a rectangular cross-sectional shape, and the backup material 52 has a circular cross-sectional shape.

[0048] Also, instead of the backup material 51, a bond breaker may be used. Thereby, the life of the sealing material can be extended. As the bond breaker, those that do not adhere to the sealing material can be used, and paper-based, cloth-based, and plastic-based adhesive tapes can be used.

[0049] In a conventional structure, in order to avoid interference between the metal fitting fastener (panel fastener 40) for fixing the panel 10 to the building frame and the base metal fitting fastener (locking metal fitting 14) for attaching the finishing material 30 to the panel 10, it is necessary to attach them with a certain distance apart. Therefore, when a plurality of base metal fittings are attached in the same direction in the length direction of the panel 10, at the longitudinal end of the panel 10, the fixing position of the finishing material 30 is provided at a position separated from the longitudinal end (horizontal joint) of the panel 10 by a certain distance, and the distance from the horizontal joint of the panel 10 to the fixing position of the finishing material 30 becomes long (x in FIG. 6). For this reason, at the longitudinal end of the finishing material 30, fluttering due to external forces such as wind loads is likely to occur.

[0050] Therefore, in the present embodiment, as shown in FIG. 9, the attachment direction of the base metal fittings 20 (the first base metal fitting 21 and the second base metal fitting 22) to the panel 10 is not the same in all directions, and at the longitudinal end of the panel 10, the attachment direction of the base metal fittings 20 to the panel 10 is changed so that the fixing position of the finishing material 30 is closer to the longitudinal end side of the panel 10. At the longitudinal end (horizontal joint) of the panel 10, reverse the mounting directions of the first base fitting 21 and the second base fitting 22 compared to the conventional method, and fix the mounting positions of the base fitting 20 to the connecting member 31 so that they face the upper end side (see Fig. 9(a)) and the lower end side (see Fig. 9(b)) of the panel 10 respectively. Thereby, the distance from the horizontal joint of the panel 10 to the fixing position of the finishing member 30 can be reduced (x1, x2 in Fig. 9).

[0051] For example, provide fasteners for base fittings in a range more than 100 mm away from the longitudinal end of the panel 10, and reverse the side (horizontal part) for fixing the finishing member 30 of the second base fitting 22 compared to the conventional method, and fix it toward (close to) the longitudinal end side of the panel 10. Thereby, it becomes possible to bring the fixing position of the end of the finishing member 30 as close as possible to the horizontal joint of the panel 10. And it is possible to suppress the flutter of the end of the finishing member 30 due to external forces such as wind load in the longitudinal direction of the finishing member 30, and stably fix the end of the finishing member 30.

[0052] And a finishing member mounting structure in which a finishing member 30 (decorative board) is mounted on the panel 1 for mounting the finishing member, and a building equipped with the finishing member mounting structure are also included in the present invention. In the finishing member mounting structure and the building of the present invention, locking of the panel and the finishing member is not inhibited (restrained) during an earthquake. Thereby, it becomes difficult to be damaged by receiving the inter-story displacement when an earthquake occurs.

[0053] <Second Embodiment> Hereinafter, a second embodiment of the base fitting and the panel for mounting the finishing member of the present invention will be described in detail with reference to the drawings. Figs. 11 to 13 are views showing the base fitting of this embodiment, (a) is a sectional view, and (b) is a top view. In the following description, mainly the parts different from the above-described first embodiment will be described, and the description of the same parts will be omitted.

[0054] The base fitting of this embodiment is a base fitting composed of a plurality of fittings for attaching a finishing material to a panel, and includes a first base fitting 21 attached to the surface of the panel 10 and a second base fitting 22 to which the finishing material is directly or indirectly attached. In the base fitting 20 of this embodiment, the first base fitting 21 is attached to the panel 10 by a mounting shaft S (first mounting shaft), and the second base fitting 22 is attached to the first base fitting 21 by a mounting shaft T (second mounting shaft) coaxial with the mounting shaft S and is rotatable in the plane on the first base fitting 21. The mounting shaft S and the mounting shaft T are separated in the out-of-plane direction in terms of the mounting position.

[0055] FIG. 11 shows a case where the cross-sectional shape of the first base fitting 21 of the base fitting of this embodiment is a U shape, FIG. 12 shows a case where the cross-sectional shape of the first base fitting 21 is a C shape (vertical direction), and FIG. 13 shows a case where the cross-sectional shape of the first base fitting 21 is a C shape (horizontal direction).

[0056] In the above-described first embodiment, the first base fitting 21 was substantially planar. However, by making the first base fitting 21 into a U-shaped or C-shaped cross section in this way, the second base fitting 22 can be attached to the first base fitting 21 by a mounting shaft T coaxial with the mounting shaft S. The mounting shaft S and the mounting shaft T are separated in the out-of-plane direction in terms of the mounting position. In this way, also in this embodiment, by shifting the mounting positions of the mounting shaft S and the mounting shaft T in the out-of-plane direction, it is possible to separate the shaft for fixing and the shaft for rotation, which contributes to the promotion of rotation and the prevention of loosening (safety) of the mounting portion.

[0057] Furthermore, since the mounting positions of the first base fitting 21 (for example, the mounting shaft S) and the second base fitting 22 (for example, the mounting shaft T) are displaced in the out-of-plane direction, the fixing degree can be set and managed individually. Therefore, for example, the first base fitting 21 is firmly fixed, and the second base fitting 22 is loosely fixed for rotation, so that during an earthquake, a difference occurs between the rotation of the first base fitting 21 and the rotation of the second base fitting 22. For example, the rotation radius and the rotation phase are different. Then, for example, by the rotation of the first base fitting 21 and the rotation of the second base fitting 22 canceling each other out, the displacement can be efficiently received, and it is possible to more reliably avoid the panel 10 and the finishing material 30 from being damaged.

[0058] As described above, the embodiments of the present invention have been described, but the present invention is not limited thereto, and can be appropriately changed without departing from the spirit of the invention. The present invention is not limited to indoor or outdoor use, and can be widely applied when attaching a finishing material to a panel.

Industrial Applicability

[0059] By using the panel for attaching a finishing material according to the present invention, it becomes difficult to be damaged by receiving the inter-story displacement when an earthquake occurs, and it can be widely used as a finishing material attachment structure of a building.
