For this reason, as shown in FIG. 2, the insertion portion 37 expands in the hollow portion 11 and returns to the original size larger than the diameter of the insertion hole 15. When the base metal fitting 32 is pulled out from the insertion hole 15 in this state, the end of the blade 37 </ b> A comes into contact with the upper surface 12 </ b> A of the hollow portion 11. That is, since the blade 37A is locked by the upper surface 12A, the removal of the base metal fitting 32 from the insertion hole 15 is restricted.

  As shown in FIG. 2, the base metal fitting 32 has a tip positioned in the hollow portion 11 in a state where the outer wall panel 1 is assembled, and the tip does not protrude forward from the back surface 10 </ b> B of the base panel 10. Therefore, since the back surface 10B of the base panel 10 is in a flat state, a plurality of outer wall panels 1 can be stacked.

[Manufacturing method of outer wall panel]
Next, a method for manufacturing the outer wall panel according to this embodiment, in which the outer wall panel 1 is manufactured, will be described.

  First, a step of preparing the base panel 10 is performed. In this step, as shown in FIG. 6, a base panel 10 having a surface 10 </ b> A, having an insertion hole 15 that opens to the surface 10 </ b> A side and communicates with the hollow portion 11 is prepared.

  Next, a step of preparing the ceramic plate 20 is performed. In this step, as shown in FIG. 6, a ceramic plate 20 having a back surface 23 attached to the front surface 10 </ b> A of the base panel 10 and having a concave hole 24 provided on the back surface 23 is prepared.

  Next, a metal fitting preparation step is performed. In this step, the decorative side metal fitting 31 described with reference to FIGS. 3 and 4 is prepared. Next, the step of preparing the base metal fitting 32 described with reference to FIG. 5 is performed. In this embodiment, the makeup side metal fitting 31 is prepared in a state where the base side metal fitting 32 is removed.

  Next, a locking process for locking the decorative side metal fitting 31 to the ceramic plate 20 is performed. Referring to FIG. 3, first, grip holes 34AA and 35AA provided at the tips 34A and 35A of the first and second arm portions 34 and 35 are gripped by a tool, and the first 34A and 35A are moved closer to each other. The second arm portions 34 and 35 are elastically deformed. Thereby, the makeup | decoration side metal fitting 31 elastically deforms from a 1st shape (shape larger than the hole 24) to a 2nd shape (shape smaller than the hole 24). And the makeup | decoration side metal fitting 31 elastically deformed to the 2nd shape is inserted in the hole 24 toward the direction orthogonal to the back surface 23 of the ceramic board 20. FIG.

  Next, by removing the tool from the gripping holes 34AA and 35AA in the hole 24, the force for holding the decorative metal fitting 31 in the second shape is released. Thereby, the 1st and 2nd arm parts 34 and 35 deform | transform in the direction which leaves | separates from the 1st virtual line 95, and the makeup | decoration side metal fitting 31 changes from 2nd shape to 3rd shape. In this state, the decorative side metal fitting 31 is locked to the ceramic plate 20. In the third shape, when a gap is generated between the outer peripheral surfaces 34C and 35C of the first and second arm portions 34 and 35 and the inner wall surface of the hole 24, the gap is filled with an adhesive. Also good.

  In this step, it is preferable that the decorative side metal fitting 31 is locked to the ceramic plate 20 so that the tips 34A, 35A of the first and second arm portions 34, 35 face downward in the longitudinal direction of the ceramic plate 20 in FIG. As shown in FIG. 1, the outer wall panel 1 is arranged in the building so that the fel-safe part 1B is positioned on the upper side in the vertical direction, so that the front ends 34A and 35A of the first and second arm parts 34 and 35 are vertically downward. It will be in a state facing the side. Thereby, as demonstrated in the experimental example mentioned later, the retention strength of the makeup | decoration side metal fitting 31 with respect to the ceramic board 20 can be improved.

  Next, a process of attaching the base metal fitting 32 to the decorative metal fitting 31 is performed. In this step, the base end 36 </ b> A (FIG. 5) of the attachment portion 36 in the base metal fitting 32 is screwed to the attachment portion 33 (FIG. 3) of the decorative metal fitting 31. Thereby, as shown in FIG. 7, the base metal fitting 32 is attached so as to stand substantially vertically with respect to the decorative metal fitting 31 on the back surface 23 side of the ceramic plate 20.

  Note that the present invention is not limited to the case where the base metal fitting 32 is attached after the decorative metal fitting 31 is locked to the ceramic plate 20 as in the present embodiment, and the makeup side metal fitting 31 with the base metal fitting 32 attached is prepared. However, this may be locked to the ceramic plate 20.

  Next, a pasting process is carried out. In this step, the base side metal fitting 32 attached to the decorative side metal fitting 31 is locked to the base panel 10 and the surface 10A of the base panel 10 and the back surface 23 of the ceramic plate 20 are bonded together as follows.

  First, the adhesive 21 is applied to the surface 10 </ b> A of the base panel 10. Next, as shown in FIG. 7, the ceramic plate 20 is positioned above the base panel 10 so that the front surface 10 </ b> A of the base panel 10 and the back surface 23 of the ceramic plate 20 face each other. At this time, the ceramic plate 20 is arranged so that the base metal fitting 32 is positioned above the insertion hole 15 of the base panel 10.

  Then, the ceramic plate 20 is lowered toward the base panel 10. Accordingly, the insertion portion 37 is inserted into the insertion hole 15 of the base panel 10 in the direction orthogonal to the back surface 23 of the ceramic plate 20 and reaches the hollow portion 11. The insertion portion 37 is reduced in diameter to the same diameter as the insertion hole 15 when passing through the insertion hole 15, but returns to the original outer diameter larger than the diameter of the insertion hole 15 in the hollow portion 11. For this reason, when the insertion portion 37 is removed from the insertion hole 15, the tip of the blade 37 </ b> A is caught on the upper surface 12 </ b> A of the hollow portion 11. In this way, the base metal fitting 32 can be locked to the base panel 10.

  Thereafter, the ceramic plate 20 is further lowered toward the base panel 10. Thereby, as shown in FIG. 8, the back surface 23 of the ceramic plate 20 comes into contact with the adhesive 21. In this way, the front surface 10 </ b> A of the base panel 10 and the back surface 23 of the ceramic plate 20 can be bonded together via the adhesive 21. In addition, when bonding the ceramic board 20 and the base panel 10, you may press the surface 25 of the ceramic board 20 to the base panel 10 side using a jig | tool not shown. The outer wall panel 1 is manufactured as described above.

(Embodiment 2)
Next, the manufacturing method of the outer wall panel which concerns on Embodiment 2 of this invention is demonstrated with reference to FIG. The manufacturing method of the outer wall panel according to the second embodiment is basically performed in the same manner as the manufacturing method of the outer wall panel according to the first embodiment, but the makeup side metal fitting 40 in which the arm connecting portion 39 is provided with the cutout portion 39A. (FIG. 9) is different in that it is prepared in the metal fitting preparation step. Only differences from the first embodiment will be described below.

  FIG. 9 shows a state (third shape) in which the decorative side metal fitting 40 used in the second embodiment is locked in the hole 24 of the ceramic plate 20 as in FIG. As shown in FIG. 9, in the third shape, the arm connecting portion 39 is formed in a region overlapping the connecting outer peripheral surface 39B along the arc of the virtual circle 91 and the intersection 93 of the virtual circle 91 and the first virtual line 95. A cut-out portion 39A. The first arm portion 34 has a third shape such that the intersection 84 of the third imaginary line 85 and the imaginary circle 91 extending from the tip 83 of the outer peripheral surface 34C through the center 92 of the imaginary circle 91 deviates from the notch 39A. The length of the outer peripheral surface 34C is set. Further, in the third shape of the second arm portion 35, the intersection 82 of the fourth virtual line 86 extending through the center 92 of the virtual circle 91 from the tip 81 of the outer peripheral surface 35C and the virtual circle 91 deviates from the cutout portion 39A. Thus, the length of the outer peripheral surface 35C is set. In the second embodiment, there are mainly four portions, that is, the distal end 34A of the first arm portion 34, the distal end 35A of the second arm portion 35, the proximal end 34B of the first arm portion 34, and the proximal end 35B of the second arm portion 35. A reaction force due to elastic deformation can be applied to the inner wall surface of the hole 24.

  The makeup side metal fitting 40 is designed to have a first shape (a shape in which insertion into the hole 24 is restricted). Then, as described in the first embodiment, the decorative side metal fitting is inserted into the hole 24 of the porcelain plate 20 by elastically deforming from the first shape to the second shape, and the force for holding the second shape is released, and the third shape is released. By adopting the shape, the decorative side metal fitting can be locked in the hole 24 of the ceramic plate 20. In the third shape, there is a possibility that a gap may be formed between the outer peripheral surfaces 34C, 35C of the first and second arm portions 34, 35 and the inner wall surface of the hole 24, while the outer peripheral surface of the arm connecting portion 39 and the hole It is difficult for a gap to form between the inner wall surfaces of 24. For this reason, when a slight dimensional error or the like occurs in the design of the decorative side metal fitting 40, the reaction force tends to concentrate on the inner wall surface of the hole 24 that contacts the outer peripheral surface of the arm connecting portion 39. Depending on the case, the locking state of the decorative side metal fitting may become unstable. On the other hand, in the present embodiment, reaction forces are respectively applied to the portions (the portion corresponding to the tip 83 and the intersection 84, the portion corresponding to the tip 81 and the intersection 82) facing the radial direction in the hole 24 of the ceramic plate 20. By adding, the locked state of the decorative side metal fitting 40 can be stabilized.

  10 and 11 are graphs showing the relationship between the amount of displacement (horizontal axis) and the tensile test force (vertical axis) of the decorative metal fitting when the decorative metal fitting is pulled out from the hole in the ceramic plate. FIG. 10 is a graph showing test results when using the decorative side metal fitting 40 (FIG. 9) in the second embodiment. FIG. 11 is a graph showing a test result when the decorative side metal fitting 31 (FIG. 3) in the first embodiment is used. The number of tests is 3, and the test results of each time are indicated by a solid line, a broken line, and a two-dot chain line in both graphs. As is clear from the comparison between FIG. 10 and FIG. 11, the variation in the test results of each time is smaller in the graph of FIG. Thus, according to the makeup | decoration side metal fitting 40 in Embodiment 2, it can be made to latch in a more stable state with respect to the ceramic board 20. FIG.

(Embodiment 3)
Next, the manufacturing method of the outer wall panel which concerns on Embodiment 3 of this invention is demonstrated with reference to FIG. The manufacturing method of the outer wall panel according to the third embodiment is basically performed in the same manner as the manufacturing method of the outer wall panel according to the first embodiment, but is different in that a base panel 16 having a solid structure is used. . Only differences from the first embodiment will be described below.

  As shown in FIG. 12, the base panel 16 has a solid structure, and is provided with an insertion hole 18 penetrating in the thickness direction. A frame 17 made of C-shaped steel is attached to the back surface 16B of the base panel 16. The frame 17 includes a first flange 17A fixed to the back surface 16B of the base panel 16, a second flange 17B parallel to the first flange 17A, one end of the first flange 17A, and one end of the second flange 17B. And a web 17C to be connected. In addition, although illustration is abbreviate | omitted, this flame | frame 17 is each provided along 4 sides of the base panel 16 which has a rectangular parallelepiped shape.

  In the bonding step, the base metal fitting 32 is inserted into the insertion hole 18 of the base panel 16 as in the first embodiment. At this time, as shown in FIG. 12, the tip of the base metal fitting 32 does not protrude forward from the frame 17 in the insertion direction. That is, the base metal fitting 32 is inserted into the insertion hole 18 so that the tip thereof is positioned on the ceramic plate 20 side with respect to the second flange 17B. For this reason, as in the first embodiment, a plurality of outer wall panels 2 can be easily stacked.

  Moreover, in Embodiment 3, the makeup | decoration side metal fitting 31 (FIG. 3) demonstrated in the said Embodiment 1 may be used, and the makeup | decoration side metal fitting 40 (FIG. 9) demonstrated in the said Embodiment 2 may be used. .

(Other embodiments)
Finally, other embodiments of the present invention will be described.

  In the first embodiment, the case where the ceramic plate 20 is used as an example of the decorative panel has been described. However, for example, a plate made of stone may be used as the decorative panel in the present invention.

  In the first embodiment, the case where one piece of ceramic board 20 is attached to one base panel 10 has been described, but the present invention is not limited to this. As shown in FIG. 13, a plurality (two) of ceramic plates 20A and 20B may be attached to one base panel. In this case, each of the ceramic plates 20A and 20B is provided with a fell-safe portion 3B by the drop-off preventing metal fitting 30, respectively.

  In the first embodiment, the case in which the base metal fitting 32 in which the insertion portion 37 is configured by an anchor spring is described, but the present invention is not limited to this. As shown in FIG. 14, a base metal fitting including an insertion portion 60 having a rotation portion 62 that rotates about a fulcrum 61 may be used. In this case, by placing the rotating portion 62 in a state parallel to the insertion hole 15 of the base panel 10 (broken line in the figure), the base metal fitting can be inserted into the insertion hole 15. Thereafter, the rotating part 62 rotates 90 ° around the fulcrum 61 by its own weight in the hollow part 11. When the base metal fitting is pulled out in this state, the rotating portion 62 comes into contact with the upper surface 12 </ b> A of the hollow portion 11. Thereby, similarly to the case where the anchor spring structure is used, the removal of the base metal fitting from the insertion hole 15 can be restricted.

(Experimental example)
An experiment was conducted to confirm the holding force when a shear load was applied to the decorative side metal fittings 31 and 40.

  As shown in FIG. 15, the makeup side metal fittings 31 and 40 are inserted into the holes 24 of the ceramic plate 20, and the base side metal fitting 32 is attached to the decoration side metal fittings 31 and 40. Next, as indicated by an upward arrow in FIG. 15, a shear load (tensile load) was applied to the decorative metal fittings 31 and 40 by pulling the base metal fitting 32 upward in the vertical direction. At this time, the shear load was adjusted to increase at a constant speed. Then, the maximum tensile load (N) applied to the decorative side metal fittings 31, 40, the displacement amount (mm) of the metal fitting when the maximum tensile load was applied, and the situation at the end of the test were confirmed. Table 1 below summarizes the conditions and results of this experiment.

  As a makeup | decoration side metal fitting, the makeup | decoration side metal fitting 31 (Test No.3-1, 3-2, 4-1, 4-2) of Embodiment 1 (FIG. 3) and the makeup side of Embodiment 2 (FIG. 9). Two types of metal fittings 40 (Test Nos. 1-1, 1-2, 2-1, 2-2) were used. Further, when the decorative side metal fittings 31 and 40 are arranged so that the tips 34A and 35A of the arm portions 34 and 35 are opposite to the load direction (tensile direction) (Test Nos. 1-1, 2-1, and 3-1). 4-1) and the case where the decorative side metal fittings 31 and 40 are arranged so that the tips 34A and 35A are in the same direction as the load direction (Test Nos. 1-2, 2-2, 3-2, 4- Experiments were conducted on 2).

  16 to 19 are graphs showing the relationship between the amount of displacement (horizontal axis) of the decorative side metal fittings 31 and 40 and the tensile load (vertical axis). FIG. It is a graph which shows the result of 1-2 and 2-2. FIG. It is a graph which shows the result of 1-1 and 2-1. FIG. It is a graph which shows the result of 3-2 and 4-2. FIG. It is a graph which shows the result of 3-1.

  From the above experimental results, it can be considered as follows.

  First, as is clear from the comparison between the graph of FIG. 16 and the graph of FIG. 17, when the tips 34A, 35A of the arm portions 34, 35 are arranged in the direction opposite to the load direction (Test Nos. 1-1, 2-1). ) Was found to have a much larger maximum load than when the tips 34A, 35A were arranged in the same direction as the load direction (Test Nos. 1-2, 2-2). This can be similarly considered from the comparison between the graph of FIG. 18 and the graph of FIG.

  Next, test no. 1-1 and test No. As is clear from the comparison of the results of 3-1, the amount of displacement at the maximum load is larger when the decorative side metal fitting 41 of FIG. 9 is used than when the decorative side metal fitting 30 of FIG. 3 is used. I understood that. It is considered that this is because, by providing the notch portion 39A, the fulcrum of the arm portions 34 and 35 is stabilized and the deflection amount of the metal fitting is increased, so that a larger displacement amount can be withstood.

  It should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
