There is an exterior member fixing structure that has a shaft portion to which the exterior member is fixed and fixes the exterior member to the ALC outer wall by using a fixing means that is fixed to the hole wall of the hole formed in the ALC outer wall. In this exterior member fixing structure, the load of the exterior member acts as a shear load around the hole of the ALC outer wall via the fixing means, so that the ALC outer wall may be deformed. Further, in this exterior member fixing structure, since the fixing means is used, rainwater or the like may enter the hole portion of the ALC outer wall along the shaft portion of the fixing means, and the water stopping property may be lowered. .. That is, in a state where the exterior member is fixed to the ALC outer wall, there is room for improvement in suppressing the deformation of the ALC outer wall and suppressing the decrease in water stopping property.

An object of the present invention is to suppress deformation of the ALC outer wall and suppress deterioration of water stopping property in a state where the exterior member is fixed to the ALC outer wall.

The exterior member fixing structure according to the first aspect has a shaft portion to which the exterior member is fixed, and has a fixing means fixed to the hole wall of the hole portion formed in the ALC outer wall and an insertion through which the shaft portion is inserted. It has a washer in which a hole is formed and is aligned with the ALC outer wall in the axial direction of the shaft portion, and a water blocking member provided between the washer and the ALC outer wall to stop water.

In the exterior member fixing structure according to the first aspect, the fixing means is arranged in the hole portion of the ALC outer wall. Further, the shaft portion of the fixing means is inserted into the washer insertion hole with the water blocking member provided between the washer and the ALC outer wall. Then, the fixing means is fixed in the hole of the ALC outer wall. Further, an exterior member is fixed to the shaft portion of the fixing means. Here, when the load of the exterior member acts on the shaft portion of the fixing means, this load is distributed to the ALC outer wall via the washer and the water blocking member around the shaft portion. That is, the area that receives the load when viewed from the axial direction of the shaft portion is expanded due to the presence of the washer around the shaft portion as compared with the case where there is no washer. As a result, the load (shear load) acting locally from the shaft portion to the periphery of the hole portion of the ALC outer wall is suppressed, so that the deformation of the ALC outer wall can be suppressed. In addition, rainwater or the like that is about to enter the hole of the ALC outer wall along the shaft portion is stopped by a water stop member provided between the washer and the ALC outer wall. As a result, it is possible to suppress a decrease in water stopping property.

A counterbore portion is formed at the peripheral edge of the opening of the hole portion in the ALC outer wall of the exterior member fixing structure according to the second aspect, and between the ALC outer wall and the water stop member and between the water stop member and the washer. On at least one of the above, an adjusting member for adjusting the position of the washer inside the counterbore portion is provided so that the surface of the ALC outer wall and the surface of the washer are aligned with each other.

In the exterior member fixing structure according to the second aspect, when the total thickness of the washer and the water blocking member is small with respect to the depth of the counterbore portion, the adjusting member is used to form the ALC outer wall. The position of the washer inside the counterbore is adjusted so that the surface and the surface of the washer are aligned. As a result, it is possible to prevent the formation of a step between the surface of the ALC outer wall and the surface of the washer.

The exterior member fixing structure according to the third aspect is provided with a pressing member that compresses the water blocking member by pressing the washer toward the ALC outer wall.

In the exterior member fixing structure according to the third aspect, the pressing member presses the washer toward the ALC outer wall. As a result, the water blocking member provided between the ALC outer wall and the washer is in a compressed state, so that the water stopping member can be improved as compared with the configuration in which the water blocking member is not compressed.

The exterior member fixing structure according to the fourth aspect is provided with a covering means between the washer and the ALC outer wall and covering the washer when viewed from the outside in the axial direction.

In the exterior member fixing structure according to the fourth aspect, the water blocking member is also covered by covering the space between the washer and the ALC outer wall and the washer by the covering means. As a result, the washer and the water blocking member cannot be visually recognized from the outside of the ALC outer wall, so that the deterioration of the design of the ALC outer wall can be suppressed.

The exterior member of the exterior member fixing structure according to the fifth aspect has a mounting member including a mounting portion attached to the main body portion of the exterior member and a fastened portion to be fastened to the shaft portion. When the mounting member is viewed from the axial direction, the width of the washer is wider than the width of the shaft portion and narrower than the width of the fastened portion.

In the exterior member fixing structure according to the fifth aspect, the washer is covered by the fastened portion of the mounting member when the mounting member is viewed from the axial direction of the shaft portion. As a result, the washer and the water blocking member cannot be visually recognized from the outside of the ALC outer wall, so that the deterioration of the design of the ALC outer wall can be suppressed.

As described above, in the exterior member fixing structure according to the present invention, in a state where the exterior member is fixed to the ALC outer wall, deformation of the ALC outer wall can be suppressed and deterioration of water stopping property can be suppressed.

As a result, as shown in FIG. 2B, the putty material 42 covers between the washer 34 and the ALC outer wall 12 and the washer 34 when viewed from the outside in the X direction. The putty material 42 is filled and applied before the bracket 22 (see FIG. 1) is fixed to the bolt 46.

[Action]
Next, the operation of the fixed structure 30 of the present embodiment will be described.

As shown in FIG. 3A, in the construction of the fixed structure 30, a counterbore portion 26 is formed on the ALC outer wall 12 and a hole portion 24 is further formed by using an electric drill or the like (not shown).

Subsequently, as shown in FIG. 3B, the anchor member 44 is inserted into the hole portion 24. On the other hand, a nut 48 and a nut 49 are screwed into the bolt 46. Then, the bolt 46 is inserted into the insertion hole 35, the through hole 37, and the through hole 39 in a state where the washer 34, the packing 36, and the spacer 38 are overlapped with each other, and is also inserted inside the anchor member 44. Here, the female screw portion 44B and the male screw portion 46A are screwed together, and the diameter of the anchor member 44 is expanded, so that the anchor member 44 is fixed to the hole wall 24A of the hole portion 24. The bolt 46 is rotated until the nut 48 comes into contact with the washer 34.

Subsequently, as shown in FIG. 3C, the putty material 42 is filled in the space inside the washer portion 26 and outside the washer 34, the packing 36 and the spacer 38, and is applied to the surface 34A of the washer 34. Will be done. As a result, as shown in FIG. 2B, the washer 34 is covered with the putty material 42 when viewed from the X direction.

Subsequently, as shown in FIG. 1, the bracket 22 is fixed to the bolt 46 by sandwiching the fastened portion 22B of the bracket 22 by the nut 48 and the nut 49 in the X direction. A column 18 of the exterior louver 17 is attached (fixed) to the bracket 22 by using a bolt (not shown). In this way, the fixing structure 30 for fixing the exterior member 14 to the ALC outer wall 12 is formed.

Here, in the fixed structure 30, when the load (mass) of the exterior member 14 acts on the bolt 46 of the fixing portion 32, this load is ALC via the washer 34 and the packing 36 arranged around the bolt 46. It is dispersed on the outer wall 12. That is, the area of the exterior member 14 that receives the load when viewed from the X direction is expanded by the presence of the washer 34 around the bolt 46 as compared with the case where the washer 34 is not present. As a result, the load acting locally from the bolt 46 to the periphery of the hole 24 of the ALC outer wall 12 (shear load acting to enlarge the hole 24) is suppressed, so that the deformation of the ALC outer wall 12 is suppressed. Can be done. In addition, rainwater or the like that is about to enter the hole 24 of the ALC outer wall 12 through the bolt 46 is stopped by the packing 36. Therefore, it is possible to suppress a decrease in water stopping property as compared with a configuration without the packing 36. As described above, in the fixed structure 30, in the state where the exterior member 14 is fixed to the ALC outer wall 12, the deformation of the ALC outer wall 12 can be suppressed and the decrease in water stopping property can be suppressed.

Further, in the fixed structure 30 shown in FIG. 2A, the sum of the thickness t5 of the washer 34 and the thickness t6 of the packing 36 is smaller than the depth t2 of the counterbore portion 26 (see FIG. 3A). ((T5 + t6) <t2). Here, in the fixed structure 30, by using the spacer 38, the position of the washer 34 inside the washer portion 26 is positioned so that the surface 12A of the ALC outer wall 12 and the surface 34A of the washer 34 are aligned in the Y direction and the Z direction. It will be adjusted. As a result, it is possible to prevent the formation of a step between the surface 12A of the ALC outer wall 12 and the surface 34A of the washer 34.

Further, in the fixed structure 30, the nut 48 presses the washer 34 toward the ALC outer wall 12. As a result, the packing 36 provided between the ALC outer wall 12 and the washer 34 is in a compressed state in the X direction, so that the water stopping property can be improved as compared with the configuration in which the packing 36 is not compressed.

In addition, in the fixed structure 30, the packing 36 and the spacer 38 are also covered by covering the space between the washer 34 and the ALC outer wall 12 and the washer 34 with the putty material 42. As a result, the washer 34, the packing 36, and the spacer 38 are not visible from the outside of the ALC outer wall 12, so that the deterioration of the design of the ALC outer wall 12 can be suppressed as compared with the configuration in which the putty material 42 is not provided.

Further, in the fixed structure 30 shown in FIG. 1, when the bracket 22 is viewed from the X direction, the width of the washer 34 (diameter d4) is wider than the width of the bolt 46 (diameter d5) in the Z direction. It is narrower than the width of 22B (W1). Therefore, when the bracket 22 is viewed from the X direction, the washer 34 is covered by the fastened portion 22B. As a result, the washer 34, the packing 36, and the spacer 38 are not visible from the outside of the ALC outer wall 12, so that the width of the washer 34 in the Z direction is wider than the width of the fastened portion 22B in the Z direction. It is possible to suppress the deterioration of the design of 12.

The present invention is not limited to the above embodiment.

In the fixed structure 30, at least one of the thickness of the washer 34 and the thickness of the packing 36 may be increased without providing the spacer 38. Further, in the fixed structure 30, instead of pressing the washer 34 by the nut 48, a spring may be provided between the nut 48 and the washer 34, and the washer 34 may be pressed by using the restoring force (elastic force) of this spring. .. Alternatively, a member extending in the radial direction from the bolt 46 may be provided, and a spring may be provided between the member and the washer to press the washer 34.

Further, in the fixed structure 30, the putty material 42 may not be used. In addition, the number of fixed structures 30 may be one or more for one ALC outer wall 12. Further, one exterior member 14 may be fixed by using the fixing structure 30 provided on the different ALC outer wall 12.

The spacer 38 may be provided between the packing 36 and the washer 34. Further, the spacer 38 may be provided both between the ALC outer wall 12 and the packing 36 and between the packing 36 and the washer 34.
