Further, when the second support portions 32L and 32R come into contact with the back surface 2B of the outer wall plate 2, the outer wall plate 2 is regulated so as not to be displaced toward the indoor direction. As a result, as shown in FIG. 14, a ventilation space S1 is secured between the structure 8 and the back surface 2B of the outer wall plate 2.

Further, the contact portions 35L and 35R, which are flush with the reference surface 15S, come into contact with the pillar member 9 to prevent the fixture 10 from rotating around the screw 10B.

Next, the next outer wall plate 2 is attached above the outer wall plate 2. As a result, the engaging recess 23A of the front side joint portion 23 of the outer wall plate 2 located on the upper side is locked by the first locking pieces 11L and 11R of the fixture 10.

At this time, the first rib 41 and the second ribs 42L, 42R formed on the bearing piece 13 come into contact with the lower end portion of the upper outer wall plate 2 from below, so that the bearing piece 13 supports the upper outer wall plate 2. To do.

Further, the first support portions 31L and 31R of the fixture 10 come into contact with the back surface 2B of the upper outer wall plate. As a result, the upper outer wall plate 2 is regulated so as not to be displaced toward the indoor direction. As a result, the ventilation space S1 is also secured between the structure 8 and the back surface 2B of the upper outer wall plate 2.

In this way, the fixture 10 supports the upper end portion of the lower outer wall plate 2 and the lower end portion of the upper outer wall plate 2 in the fixed state. By carrying out such work on the other outer wall plates 2, each outer wall plate 2 is supported by each pillar member 9 in a state of being adjacent to each other in the vertical direction and the horizontal direction, and covers the outer surface of the structure 8.

As shown in FIG. 6, when the outer wall plate 2 is vertically stretched by the fixture 10, the case where the outer wall plate 2 is horizontally stretched by the fixture 10 is rotated 90 ° clockwise. The description is omitted.

Although not shown, when the outer wall plate 2 is horizontally stretched, the fixture 10 is arranged at a position where the corners of the four outer wall plates 2 adjacent to each other in the vertical direction and the horizontal direction are abutted with each other. It is also possible to support the corners of each outer wall plate 2. In this case, the second locking piece 12L locks the upper right corner of the outer wall plate 2 on the lower left side. The second locking piece 12R locks the upper left corner portion of the outer wall plate 2 on the lower right side. The first locking piece 11L locks the lower right corner of the outer wall plate 2 on the upper left side. The first locking piece 11R locks the lower left corner of the outer wall plate 2 on the upper right side.

Further, although not shown, an additional attachment may be arranged between the plurality of attachments 10 to more firmly support the adjacent outer wall plates 2.

<Effect>
When the fixture 10 of the embodiment is attached, when the fixing portion 15 is fixed to the structure 8 by an excessive fastening force, the fixing portion 15 is deformed so that the peripheral portion of the fixing portion 15 floats from the structure 8. There is a risk that the force that causes it will act. Specifically, as shown in FIGS. 5 and 6, the screw 10B inserted into the first fixing hole 17 or the like is deeply screwed into the pillar member 9, so that the periphery of the first fixing hole 17 or the like in the fixing portion 15 is formed. When a force that causes the pillar member 9 to be excessively approached is applied, the upper end portion, the lower end portion, the left end portion, and the right end portion of the fixing portion 15 are subjected to the two-dot chain lines C1 to C4 in FIGS. As shown by, there is a possibility that a force that causes the column member 9 to float or distort the column member 9 acts on the column member 9.

Here, in the fixture 10, the first locking pieces 11L and 11R are divided into two by the notch 19 in the width direction of the bearing piece 13. As a result, even if a force for deforming the fixed portion 15 as shown by the alternate long and short dash lines C1 to C4 in FIGS. 5 and 6 is generated, the force is applied to the first locking pieces 11L and 11R via the bearing piece 13. It is difficult to transmit, and it prevents warpage and distortion of each of the first locking pieces 11L and 11R. As a result, it is possible to prevent the outer wall plate 2 from being locked at a position where the first locking pieces 11L and 11R deviate from the proper positions. Then, even when an external force acts on the fixture 10 due to wind pressure, an earthquake, or the like after construction, the outer wall plate 2 can be suitably restrained by the first locking pieces 11L and 11R, which are less likely to warp or distort. It is possible to suppress the occurrence of problems such as damage or a gap in the joint portion between the outer wall plates 2, for example, the joint portion 25 shown in FIG.

Therefore, according to the attachment 10 and the exterior structure of the embodiment, the outer wall plate 2 can be stably attached to the pillar member 9 or the like of the structural material 8.

Further, in the attachment 10, two second locking pieces 12L and 12R are formed in the width direction of the bearing piece 13. The left second locking piece 12L is arranged at a position corresponding to the left first locking piece 11L. Further, the second locking piece 12R on the right side is arranged at a position corresponding to the first locking piece 11R on the right side. By providing such second locking pieces 12L and 12R, in this fixture 10, the upper end portion of the outer wall plate 2 is suitably locked at two places, and the outer wall joined in the width direction of the bearing piece 13 is provided. The upper ends of the plates 2 can be suitably locked.

Further, in the fixture 10, as shown in FIG. 14, the fixture 10 is screwed by the contact portions 35L and 35R abutting on the pillar 9 in a state where the fixing portion 15 is fixed to the pillar 9. It is possible to prevent the position from shifting by rotating around 10B. Therefore, the outer wall plate 2 can be stably attached to the structure 8.

Further, in the fixture 10, as shown in FIG. 13, the contact portions 35L and 35R are formed with substantially C-shaped slits at two positions of the fixing portion 15, and the inner portion surrounded by the slits faces downward. It is cut up into two pieces. Therefore, as shown in FIGS. 5 and 6, even if the pillar 9 is a thin stud and the fixing portion 15 is fixed at a position deviated from the center of the pillar 9, the two contact portions 35L Since at least one of the 35Rs can come into contact with the pillar member 9, the rotation of the fixture 10 around the screw 10B can be effectively prevented. Further, since the contact portions 35L and 35R are cut and raised from the fixed portion 15, the strength decrease of the bearing piece 13 can be suppressed as compared with the case where the contact portions 35L and 35R are cut and raised from the bearing piece 13.

Further, in the fixture 10, the first locking pieces 11L and 11R are divided by the notch 19 in the central portion in the width direction of the bearing piece 13, so that the area of the first locking pieces 11L and 11R and the area of the first locking pieces 11R and 11R are increased. The strength can be secured evenly. Therefore, the external force acting on the fixture 10 can be satisfactorily dispersed, and the first locking pieces 11L and 11R are less likely to be warped or distorted. Further, as shown in FIG. 5 and the like, when the outer wall plate 2 is horizontally stretched by the attachment 10, the water accumulated in the bearing piece 13 can be suitably drained by the notch 19.

Further, in the attachment 10, as shown in FIGS. 8, 9 and 11, the bearing piece 13 extends from the vicinity of the fixing portion 15 to the vicinity of the first locking pieces 11L and 11R at the central portion in the width direction of the bearing piece 13. The bearing piece 13 is reinforced by forming the first rib 41. With such a bearing piece 13, the outer wall plate 2 can be more preferably supported.

Further, in the attachment 10, as shown in FIGS. 8 and 9, the second ribs 42L extending from the fixing portion 15 to the vicinity of the first locking pieces 11L and 11R at both ends in the width direction of the bearing piece 13 The bearing piece 13 is reinforced by forming 42R. The outer wall plate 2 can be more preferably supported by such a bearing piece 13.

Further, in the fixture 10, as shown in FIG. 8, the length W19 of the support piece 13 of the notch 19 in the width direction is set to be smaller than the inner diameter D17 of the first fixing hole 17, so that the notch 19 is set. The area and strength of the first locking pieces 11L and 11R can be suitably secured without unnecessarily increasing the width of the first locking pieces. Therefore, the external force acting on the fixture 10 can be satisfactorily dispersed, and the first locking pieces 11L and 11R are less likely to be warped or distorted.

Further, in the fixture 10, as shown in FIG. 11, the axial center X17 of the first fixing hole 17 provided in the fixing portion 15 is a bearing piece as it goes from the fixing portion 15 toward the first locking pieces 11L and 11R. It is inclined so as to be separated upward from 13. Then, as shown in FIG. 8, at the first distance L1 in which the tips 11E of the first locking pieces 11L and 11R are separated upward from the bearing piece 13, the lower end 17E of the first fixing hole 17 is upwardly separated from the bearing piece 13. It is set to be larger than the second distance L2 that is separated. As a result, in the fixture 10, the second distance L2 is reduced while suppressing the screw 10B from interfering with the tips 11E of the first locking pieces 11L and 11R, and the first fixing hole 17 is made into the bearing piece 13. It can be installed in a close position. As a result, the fixing portion 15 can be firmly fixed to the structure 8 by the screw 10B inserted into the first fixing hole 17. Further, even when the outer wall plate 2 is vertically stretched on the pillar material 9 which is a thin stud, the screw 10B is inserted into the first fixing hole 17 located near the support piece 13 so as to the pillar material 9 of the fixture 10. It is easy to arrange the mounting position in the center of the pillar material 9.
