By the way, in the structure of the peripheral part of the outer wall surface material of Patent Document 1, the lower end of the outer wall surface material is exposed when viewed from the outside (outdoor side) in the inside-outside direction. For this reason, when there is a step at the lower end of the adjacent outer wall surface material, the step is visible, which degrades the appearance of the building.

In addition, in the configuration in which a member of a predetermined size is brought into contact with the outer wall surface material as in Patent Document 1, when the thickness of the outer wall surface material is changed, the member is adjusted to match the size of the outer wall surface material. may have to be replaced. In other words, the versatility of the member to be brought into contact with the exterior wall surface material is low.

In other words, there is room for improvement in order to prevent the building from becoming unattractive and to increase versatility in a building in which there is a step at the lower end of the adjacent exterior wall surface material.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an exterior wall decorative material and a base drain that can prevent the appearance of a building having a step at the lower end of adjacent exterior wall materials from becoming unattractive and increase versatility. .

The exterior wall decorative material according to the first aspect is arranged on the lower side in the height direction of a plurality of exterior wall surface materials arranged in the orthogonal direction perpendicular to the height direction of the building, and the base to which the exterior wall surface material is attached. and a fixing part fixed to the outer wall member, which is arranged outside the fixing part in an internal/external direction orthogonal to the height direction and the orthogonal direction, and covers the lower end of the outer wall surface material when viewed from the internal/external direction. It has a covering portion, and an expandable portion that connects the fixed portion and the covering portion in the inside-out direction and is expandable in the inside-out direction.

In the external wall decorative material according to the first aspect, the external wall decorative material is fixed to the base part by fixing the fixing part to the base part. When the exterior wall decorative material is fixed to the base portion, the covering portion covers the lower end portion of the exterior wall surface material when viewed from the inside and outside. Accordingly, when there is a step at the lower end of the adjacent outer wall surface material, the step is covered with the covering portion, so that it is possible to prevent the appearance of the building from deteriorating.

Furthermore, in the exterior wall decorative material according to the first aspect, the stretchable portion is stretchable in the inward and outward directions. As a result, when the thickness of the outer wall surface material is changed, the expansion/contraction part is expanded and contracted according to the thickness of the outer wall surface material, so that the position of the covering part is changed and the covering part and the outer wall surface material are brought into contact with each other. be in close contact. In this way, by expanding and contracting the elastic part in one exterior wall decorative material, there is no need to manufacture exterior wall decorative materials with different thicknesses according to the thickness of the exterior wall surface material, so the versatility of the external wall decorative material is increased. can be enhanced. In summary, with the exterior wall decorative material according to the first aspect, it is possible to suppress deterioration in the appearance of a building in which there is a step at the lower end of the adjacent exterior wall surface material, and to increase the versatility of the external wall decorative material. .

The stretchable portion of the exterior wall decorative material according to the second aspect has an elastic member that is elastically deformable in the inward and outward directions.

In the external wall decorative material according to the second aspect, a thick external wall surface material is used, and when the covering portion is displaced away from the fixing portion, the elastic member is pulled in the inward and outward directions, thereby A tensile force on the side closer to the fixed portion acts on the portion. As a result, when the thickness of the exterior wall material is changed, the contact state between the exterior wall material and the covering portion is ensured, so that the lower end portion of the exterior wall material can be made more difficult to see.

A plurality of the elastic members of the external wall decorative material according to the third aspect are arranged at intervals in the orthogonal direction.

In the external wall decorative material according to the third aspect, the plurality of elastic members are arranged with intervals in the orthogonal direction, so that spaces are formed between the adjacent elastic members. For this reason, each elastic member is more likely to be elastically deformed between the fixing portion and the covering portion than in a configuration in which one elastic member is provided over the entire orthogonal direction. As a result, when the thicknesses of the outer wall surface materials arranged in the orthogonal direction are different in the orthogonal direction, it is possible to easily adjust the inclination of the arrangement direction of the covering portion with respect to the orthogonal direction according to the thickness of the outer wall surface material. .

A base drainer according to a fourth aspect is the exterior wall decorative material according to any one of the first aspect to the third aspect, wherein the exterior wall decorative material includes an engaged portion formed on the fixing portion; A draining body having an engaging portion that engages with a to-be-engaged portion, and arranged below the outer wall decorative material in the height direction and outside the outer peripheral portion of the foundation of the building in the inside and outside direction. and

In the base drainer according to the fourth aspect, the base drainer is attached to the base portion by engaging the engaging portion of the drainer body portion with the engaged portion of the fixed portion fixed to the base portion. In this way, when the drainer main body is attached to the base portion, it is sufficient to engage the engaging portion and the engaged portion. Therefore, it is possible to improve the workability of installing the base drain.

The drainer main body part of the base drainer according to the fifth aspect has an extension part extending from the engaged part to the outside of the outer wall decorative material in the inner-outer direction.

In the base drainer according to the fifth aspect, the extension part of the drainer main body part extends outside the outer wall decorative material in the inside-outside direction. Here, since the extending portion extends below the covering portion, the covering portion can be supported by the extending portion when the covering portion is lowered in the height direction. can.

The drainer main body portion of the base drainer according to the sixth aspect includes an inner wall on which the engaging portion is formed, and is arranged outside the inner wall in the inner-outward direction with respect to the inner wall, and when viewed from the inner-outer direction, the an outer wall covering the inner wall.

In the base drainer according to the sixth aspect, the outer wall covers the inner wall when viewed from the inside and outside. In other words, the area of the outer wall when viewed from the inside and outside is larger than the area of the inner wall. The inner wall and the outer wall are integrated as a drainer body. Therefore, when the engaging portion and the engaged portion are engaged by applying an external force to the inner wall, even if the inner wall has a small area and it is difficult to apply the external force, the outer side having a large area can be used. By applying an external force to the wall, the external force can be applied to the engaging portion. By having the outer wall in this way, a large external force can be applied to the engaging portion.

The outer wall frame 22 is a member that extends in the X direction and has an inverted U-shaped cross section when viewed from the X direction. Specifically, when viewed from the X direction, the outer wall frame 22 includes an inner wall portion 22A standing upright in the Z direction, an upper wall portion 22B extending outward in the Y direction from the upper end of the inner wall portion 22A in the Z direction, and an upper wall and an outer wall portion 22C extending downward in the Z direction from the outer end of the portion 22B.

The inner wall portion 22A is formed with a through hole 18A through which only the shaft portion of the bolt 19A can be inserted. In addition, the inner wall portion 22A is fastened to the floor girder 18 using bolts 19A and nuts 19B. The outer wall portion 22C is formed so that a screw 23 and a screw 26 can be fastened (screwed) in the Y direction. An outer wall surface member 24, which will be described later, is attached to the outer wall portion 22C in the Y direction.

In the following description, one set (two) of exterior wall surface materials 24 adjacent in the X direction may be distinguished by referring to one side as an exterior wall surface material 24A and the other side as an exterior wall surface material 24B. In some cases, the Z-direction lower end surface of the outer wall surface material 24A is referred to as a lower end surface 27A, and the Z-direction lower end surface of the outer wall surface material 24B is referred to as a lower end surface 27B. When the distinction is unnecessary, they are simply referred to as the outer wall surface material 24 and the lower end surface 27 .

The outer wall surface material 24A and the outer wall surface material 24B are in contact (close contact) in the X direction. In addition, the outer wall surface material 24A and the outer wall surface material 24B are attached to the outer wall frame 22 separately. Therefore, there is a possibility that a step 29 (see FIG. 6A) due to the difference in height in the Z direction may occur between the lower end surfaces 27A and 27B due to positional deviation that occurs during the mounting work. In the following description, the lower end portion 25 of the outer wall surface material 24 means a portion of the outer wall surface material 24 that includes the lower end surfaces 27A and 27B and forms the step 29 .

Further, the fixing member 34 has, for example, a vertical wall 42, an inclined wall 43, a lower wall 44, an upper wall 45, and an engaged portion 46 when viewed from the X direction. As an example, the vertical wall 42, the inclined wall 43, the lower wall 44, the upper wall 45, and the engaged portion 46 are integrally formed and have the same length in the X direction. In other words, the fixing member 34 is formed as one long member in the X direction. Further, the fixing member 34 is made of aluminum, for example.

The vertical wall 42 is formed in a plate shape with the Y direction as the thickness direction, and extends in the Z direction when viewed from the X direction. The length corresponding to the height of the vertical wall 42 in the Z direction is longer than the length corresponding to the outer diameter of the head of the screw 26 (see FIG. 1). The vertical wall 42 is formed in a rectangular shape that is long in the X direction and short in the Z direction when viewed from the Y direction. The length of the vertical wall 42 in the X direction is longer than the length of the outer wall surface material 24 (see FIG. 1) in the X direction. Furthermore, the Y-direction inner side surface of the vertical wall 42 is a plane along the XZ plane. As a result, the side surface of the vertical wall 42 and the outer wall portion 22C (see FIG. 1) are in surface contact.

A fastening hole 49 penetrating through the vertical wall 42 in the Y direction is formed in the central portion of the vertical wall 42 in the Z direction. A plurality of fastening holes 49 are formed at intervals in the X direction. Further, the fastening hole 49 is formed in a circular shape when viewed from the Y direction. The size of the fastening hole 49 is such that the shaft portion of the screw 26 (see FIG. 1) can be screwed into it.

The inclined wall 43 is a portion that is inclined obliquely from the lower end of the vertical wall 42 so that the lower end in the Z direction is located outside the upper end in the Y direction when viewed from the X direction. The inclined wall 43 is formed to suppress interference with the rat-proof net 28 (see FIG. 1).

The lower wall 44 is formed in a plate shape having a thickness direction in the Z direction, and extends outward along the Y direction from the lower end of the inclined wall 43 when viewed from the X direction. The length of the lower wall 44 in the Y direction is, for example, approximately half the length of the outer wall surface material 24 (see FIG. 1) in the Y direction.

The upper wall 45 is formed in a plate shape having a thickness direction in the Z direction, and extends outward along the Y direction from the upper end portion of the vertical wall 42 when viewed from the X direction. For example, the length of the upper wall 45 in the Y direction is approximately the same as the length of the lower wall 44 in the Y direction. The upper surface of the upper wall 45 is a flat surface along the XY plane, and can come into surface contact with the lower end surface 27 (see FIG. 1) in the Z direction. The length in the Y direction from the inner end of the vertical wall 42 in the Y direction to the outer end of the upper wall 45 in the Y direction is L1 [mm]. Also, the height in the Z direction of the lower surface of the upper wall 45 with respect to the upper surface of the lower wall 44 is h1 [mm].

The engaged portion 46 is formed on the fixed member 34 . Specifically, the engaged portion 46 includes a lower vertical wall 47 erected in the Z direction from a portion of the upper surface of the lower wall 44 and a portion of the lower surface of the upper wall 45 when viewed in the X direction. and an upper vertical wall 48 extending downward in the Z direction from the . The lower vertical wall 47 and the upper vertical wall 48 are matched in shape and size. The lower vertical wall 47 and the upper vertical wall 48 extend in the X direction. The shape of the lower vertical wall 47 and the upper vertical wall 48 is a rectangular shape that is short in the Y direction and long in the Z direction when viewed from the X direction. Both ends of the lower vertical wall 47 and the upper vertical wall 48 in the X direction are connected in the Z direction.

The lower vertical wall 47 and the upper vertical wall 48 are opposed to each other with a gap in the Z direction. The distance between the lower vertical wall 47 and the upper vertical wall 48 is larger than the outermost diameter of the screw 26 (see FIG. 1) when viewed in the Y direction. In addition, the lower vertical wall 47 and the upper vertical wall 48 are opposed to the vertical wall 42 with a gap in the Y direction. The distance between the lower vertical wall 47 and the upper vertical wall 48 and the vertical wall 42 in the Y direction is larger than the size of the head of the screw 26 in the Y direction.

(coating member)
The covering member 36 is an example of a covering portion. Also, the covering member 36 is arranged outside the fixing member 34 in the Y direction. Furthermore, the covering member 36 has an L-shaped cross-sectional shape when viewed from the X direction and extends in the X direction. Specifically, when viewed from the X direction, the covering member 36 is integrated with a plate-like lateral wall 37 whose thickness direction is the Z direction and a plate-like parting wall 39 whose thickness direction is the Y direction. formed as one integrated member. In addition, the covering member 36 is made of aluminum, for example.

The lateral wall 37 has a thickness comparable to that of the top wall 45 . The height of the upper surface of the lateral wall 37 in the Z direction and the height of the upper surface of the upper wall 45 in the Z direction are substantially the same. In the horizontal wall 37, the length in the Y direction from the inner end in the Y direction to the parting wall 39 is L2 [mm]. L2<L1.

The parting wall 39 is erected upward in the Z direction from the outer end of the lateral wall 37 in the Y direction. Moreover, the parting wall 39 has the same thickness as the lateral wall 37 . The height h2 [mm] of the parting wall 39 in the Z direction is such that when the parting wall 39 and the outer wall panel 20 (see FIG. 6B) are viewed from the outside in the Y direction, the step 29 (see FIG. 6B) is outside the Y direction. is set to be covered from In other words, the covering member 36 is formed so as to cover the lower end portion 25 of the outer wall surface member 24 when viewed in the Y direction.

The length corresponding to the height h2 is, for example, longer than the length L2 and shorter than the length L1. The side surface of the parting wall 39 on the inner side in the Y direction is a flat surface along the XZ plane, and can be in surface contact with the outer wall surface member 24 (see FIG. 1).

(Expansion member)
The elastic member 38 shown in FIG. 2 is an example of an elastic portion. Specifically, the elastic member 38 has a plurality of rubber plates 41 made of silicone rubber as an example of an elastic member. The plurality of rubber plates 41 are arranged at intervals in the X direction. Note that each of the plurality of rubber plates 41 has the same configuration. Therefore, in the following description, it is simply referred to as "rubber plate 41".

The rubber plate 41 shown in FIG. 3 is formed in a plate shape with the Z direction as the thickness direction. The shape of the rubber plate 41 is, for example, a rectangular shape that is short in the X direction and long in the Y direction when viewed from the Z direction. The thickness of the rubber plate 41 is, for example, approximately the same as the thickness of the upper wall 45 or the thickness of the lateral wall 37 . For example, the height of the top surface of the rubber plate 41 in the Z direction is aligned with the height of the top surface of the upper wall 45 and the height of the top surface of the lateral wall 37 .

The Y-direction inner end surface of the rubber plate 41 is, for example, adhered (fixed) to the Y-direction outer end surface of the upper wall 45 using an adhesive (not shown). The Y-direction outer end face of the rubber plate 41 is, for example, adhered (fixed) to the Y-direction inner end face of the lateral wall 37 using an adhesive (not shown). The rubber plate 41 is formed to be elastically deformable in the Y direction. In this manner, the rubber plate 41 is elastically deformed in the Y direction so that the relative position of the lateral wall 37 with respect to the upper wall 45 in the Y direction can be changed. In other words, the elastic member 38 connects the fixing member 34 and the covering member 36 in the Y direction, and the elastic member 38 itself can be expanded and contracted in the Y direction.

The size and arrangement of the rubber plate 41 are set in advance so that the rubber plate 41 can expand and contract in the Y direction, and the rubber plate 41 can hold the parting wall 39 so as to suppress its tilt in the Z direction. Let L3 [mm] be the natural length of the rubber plate 41 from the inner end to the outer end in the Y direction (the length in a state in which it is not elastically deformed). Also, when the rubber plate 41 is stretched from its natural length state, or when the rubber plate 41 is contracted after being stretched to some extent, the length from the inner end to the outer end of the rubber plate 41 in the Y direction is L4 [mm].

Here, when each member is not replaced, the length L1 and the length L2 are constant, but the length L4 is variable within a set range. That is, the total length LS [mm]=L1+L2+L4 in the Y direction is variable by expanding and contracting the rubber plate 41 in the Y direction.

It should be noted that the extension of the elastic member 38 means that the rubber plate 41 is extended from its natural length. Further, contraction of the elastic member 38 means that the rubber plate 41 is elongated to a certain length from its natural length and then elongated to a length shorter than this length. In this way, when the thickness of the outer wall surface material 24 (see FIG. 1) is changed, the outer wall decorative material 32 is such that the elastic member 38 expands and contracts in the Y direction according to the thickness of the outer wall surface material 24 in the Y direction. Therefore, it can be used for a plurality of types of exterior wall surface materials 24 having different thicknesses.

The inner wall 53 shown in FIG. 4 is formed in a plate shape with the Y direction as the thickness direction. The height h3 [mm] of the inner wall 53 in the Z direction is slightly lower than the height h1 (see FIG. 3). As a result, the inner wall 53 can be inserted between the lower wall 44 and the upper wall 45 (see FIG. 3) from the outside in the Y direction toward the engaged portion 46 while being straight in the Z direction. ing. A lower end portion of the inner wall 53 contacts the lower vertical wall 47 (see FIG. 3) from the outside in the Y direction. The upper end of the inner wall 53 contacts the upper vertical wall 48 (see FIG. 3) from the outside in the Y direction. An engaging portion 60, which will be described later, is formed on the inner surface of the inner wall 53 in the Y direction.

The upper wall 54 is an example of an extension. The upper wall 54 is formed in a plate shape having a thickness direction in the Z direction. When viewed from the X direction, the upper wall 54 extends outward along the Y direction from the upper end of the vertical wall 42 . In other words, the upper wall 54 extends from the engaging portion 60 to the outside of the outer wall decorative member 32 (see FIG. 1) in the Y direction. Specifically, the upper wall 54 extends outward in the Y direction from a portion slightly below the upper end of the inner wall 53 and outside in the Y direction when viewed in the X direction. exist. The length of the upper wall 54 in the Y direction is such that when the drainer main body 52 is attached to the fixing member 34 (see FIG. 3), the outer portion of the upper wall 54 in the Y direction is are set in advance so that they are arranged outside in the Y direction.

The outer wall 55 is formed in a plate shape having a thickness direction in the Y direction. The outer wall 55 extends downward in the Y direction from the Y-direction outer end of the upper wall 54 when viewed in the X direction. Furthermore, the outer wall 55 is formed in a rectangular shape that is long in the X direction and short in the Z direction when viewed from the Y direction. In addition, the outer wall 55 is arranged outside the inner wall 53 in the Y direction and covers the inner wall 53 when viewed in the Y direction. In other words, the inner wall 53 is arranged inside the region of the outer wall 55 when the outer wall 55 is projected in the Y direction. The area of the outer wall 55 is larger than the area of the inner wall 53 when viewed in the Y direction.

The lateral wall 56 extends inward in the Y direction from a portion slightly above the lower end of the outer wall 55 in the Z direction. The length of the lateral wall 56 in the Y direction is less than 1/3 of the length of the top wall 54 in the Y direction.

The lower wall 57 is formed in a plate shape having a thickness direction in the Y direction. The lower wall 57 extends downward in the Y direction from the Y-direction inner end of the lateral wall 56 when viewed in the X direction. The lower wall 58 extends inward in the Y direction from a portion slightly above the lower end of the lower wall 57 in the Z direction. The Y-direction length of the lower wall 58 is longer than the Y-direction length of the lateral wall 56 and shorter than the Y-direction length of the upper wall 54 . The Y-direction inner end of the lower wall 58 is bent downward.

The attached portion 59 has, for example, a raised portion 59A that stands upright from the upper surface of the lower wall 58 upward in the Z direction, and a protruding portion 59B that protrudes downward from the lower surface of the upper wall 54 . The rising portion 59A is formed in a substantially rectangular shape that is longer in the Z direction than in the Y direction when viewed from the X direction. In addition, the upright portion 59A forms a substantially U-shaped cross section that opens upward in the Z direction together with the lower wall 57. As shown in FIG.

The projecting portion 59B is formed in an inverted L shape when viewed from the X direction. In addition, the projecting portion 59B forms a substantially U-shaped cross section opening outward in the Y direction together with the upper wall 54 . Here, two draining body portions 52 adjacent in the X direction are connected by a joiner (connecting material) 51 .

As an example, the joiner 51 is formed to have a cross-sectional shape substantially similar to a part of the drainer main body 52 when viewed from the X direction. The joiner 51 is arranged along the Y-direction inner surface and the Z-direction lower surface of the drainer main body 52 . The Z-direction lower end of the joiner 51 is inserted between the lower wall 57 and the rising portion 59A, and the Z-direction upper end of the joiner 51 is inserted between the upper wall 54 and the projecting portion 59B. It is designed to be

The inner portion in the Y direction of the lower claw portion 62 is bent upward in the Z direction with respect to the outer portion. A protruding portion that protrudes upward is formed in this bent portion. The inner portion in the Y direction of the upper claw portion 64 is bent downward in the Z direction with respect to the outer portion. A protruding portion that protrudes downward is formed in this bent portion.

The lower claw portion 62 and the upper claw portion 64 are opposed to each other with a gap in the Z direction. In addition, the lower claw portion 62 and the upper claw portion 64 are arranged vertically symmetrically with respect to the center of the inner wall 53 in the Z direction. When viewed in the X direction, the length corresponding to the height from the lowermost portion of the lower claw portion 62 to the uppermost portion of the upper claw portion 64 is the length of the lower vertical wall 47 and the upper vertical wall. It is slightly longer than the length corresponding to the Z-direction spacing from wall 48 (see FIG. 3). As a result, when an external force directed inward in the Y direction is applied to the drainer main body portion 52, the lower claw portion 62 and the upper claw portion 64 move the lower vertical wall 47 and the upper vertical wall 48 inward in the Y direction. By moving over, the engaging portion 60 and the engaged portion 46 (see FIG. 3) are engaged.

[Action]
Next, the operation of the external wall decorative material 32 and the base drainer 30 according to this embodiment will be described.

As shown in FIG. 5A, an exterior wall panel 24 is attached to the exterior wall frame 22 using screws 23 . A plurality of exterior wall surface members 24 are arranged in contact with each other in the X direction and attached to the exterior wall frame 22 . Let T1 [mm] be the thickness of the outer wall surface material 24 in the Y direction.

The outer wall panel 24A and the outer wall panel 24B shown in FIG. 6A are attached separately to the outer wall frame 22 (see FIG. 5A). Therefore, a step 29 may occur between the lower end surface 27A and the lower end surface 27B due to a positional deviation that occurs during the mounting work.

Subsequently, as shown in FIG. 5A , the vertical wall 42 is pushed against the rat-proof net 28 in the Y-direction while the upper part of the rat-proof net 28 is pressed against the outer wall frame 22 from the outside in the Y direction. pressed from the outside of the At this time, the upper wall 54 is in contact with the lower end surface 27 of the outer wall surface member 24 . The covering member 36 covers the Y-direction outer lower end portion 25 of the outer wall surface member 24 from the Y-direction outer side. In this state, the vertical wall 42 and the rat-proof net 28 are fastened together to the outer wall frame 22 using the screws 26 , thereby fixing the outer wall decorative material 32 to the outer wall frame 22 .

As shown in FIG. 6B, even if there is a step 29 between the lower end surface 27A and the lower end surface 27B, when viewed from the outside in the Y direction, the outer wall decorative material 32 (coating member 36) does not cover the lower end portion 25. is covered, the step 29 becomes invisible. This prevents the building 10 from looking bad.

As shown in FIG. 7A, it is assumed that the thickness of the outer wall surface material 24 in the Y direction is T1 [mm] and the total length of the outer wall decorative material 32 is LS=T1. Furthermore, it is assumed that the upper wall 54 , the rubber plate 41 , the lateral wall 37 and the parting wall 39 are in contact with the outer wall surface material 24 .

Here, as shown in FIG. 7B, the thickness in the Y direction of the exterior wall panel 72 used in other buildings or replaced due to design changes or the like is T2 [mm] (T2>T1). Suppose there was In this case, by fixing the exterior wall decorative material 32 to the exterior wall frame 22 (see FIG. 1), the rubber plate 41 is elastically deformed (stretched) in the Y direction. Therefore, the parting wall 39 can be slid in the Y direction while maintaining the height position of the parting wall 39 in the Z direction, so that the outer wall decorative material 32 can keep the lower end 25 covered. can.

Subsequently, an external force F is applied by a hammer (not shown) to the outer wall 55 of the drainer main body 52 while the engaged portion 46 and the engaging portion 60 shown in FIG. 5B are aligned in the Y direction. Thereby, the engaging portion 60 is engaged with the engaged portion 46 . Specifically, the lower claw portion 62 and the upper claw portion 64 (see FIG. 4) are inserted from the outside in the Y direction between the lower vertical wall 47 and the upper vertical wall 48 (see FIG. 3). The lower vertical wall 47 and the upper vertical wall 48 are then brought into contact with the inner wall 53 . As a result, the drainer body 52 is fixed to the outer wall decorative material 32, and the base drainer 30 is completed. The base drainer 30 drains rainwater and the like.

As described above, the external wall decorative material 32 is fixed to the external wall frame 22 by fixing the fixing member 34 to the external wall frame 22 . When the exterior wall decorative material 32 is fixed to the exterior wall frame 22, the covering member 36 covers the lower end portion 25 of the exterior wall surface member 24 when viewed from the Y direction. As a result, when there is a step 29 (see FIG. 6B) at the lower end portion 25 of the adjacent outer wall surface material 24, the step 29 is covered with the covering member 36, so that the appearance of the building 10 is deteriorated (step 29 remains exposed).

Furthermore, in the exterior wall decorative material 32, the elastic member 38 is expandable in the Y direction. As a result, when the thickness T of the outer wall surface material 24 is changed, the expansion/contraction member 38 is expanded and contracted according to the thickness T, so that the position of the covering member 36 is changed and the covering member 36 and the outer wall surface material 24 are in close contact with each other. In this way, by expanding and contracting the elastic member 38 in one external wall decorative material 32, it is not necessary to manufacture the external wall decorative material 32 with different thicknesses according to the thickness T of the external wall surface material 24. The versatility of the material 32 can be enhanced. In summary, the exterior wall decorative material 32 can suppress deterioration of the appearance of the building 10 in which the step 29 is formed at the lower end portion 25 of the adjacent exterior wall surface material 24, and enhance the versatility of the external wall decorative material 32. can. In addition, "versatility" in this embodiment means that the exterior wall decorative material 32 can be used for a plurality of types of exterior wall surface materials 24 having different thicknesses.

When the outer wall decorative member 32 uses a relatively thick outer wall surface member 24 and the covering member 36 is displaced away from the fixing member 34, the rubber plate 41 is pulled in the Y direction. As a result, a tensile force on the side closer to the fixing member 34 acts on the covering member 36 . Thereby, when the thickness T of the outer wall surface material 24 is changed, the contact state between the outer wall surface material 24 and the covering member 36 is ensured, so that the lower end portion 25 of the outer wall surface material 24 is made more difficult to be visually recognized. be able to.

Furthermore, in the external wall decorative material 32, a plurality of rubber plates 41 are arranged at intervals in the X direction, so that spaces are formed between adjacent rubber plates 41. As shown in FIG. Therefore, each rubber plate 41 is more likely to be elastically deformed between the fixing member 34 and the covering member 36 than in a configuration in which one rubber plate 41 is provided over the entire X direction. As a result, when the thickness T of the outer wall surface materials 24 arranged in the X direction is different in the X direction, the inclination of the arrangement direction of the covering member 36 with respect to the X direction is adjusted according to the thickness T of the outer wall surface materials 24. can be made easier.

In the base drainer 30, the base drainer 30 is attached to the outer wall frame 22 by engaging the engaging portion 60 of the drainer body portion 52 with the engaged portion 46 of the fixing member 34 fixed to the outer wall frame 22. Mounted. In this way, when attaching the drainer main body 52 to the outer wall frame 22, the engaging part 60 and the engaged part 46 can be engaged. It is possible to improve the workability of mounting the base drainer 30 compared to the structure in which the base drainer 30 is fastened.

In addition, in the base drainer 30, the upper wall 54 of the drainer main body portion 52 extends to the outside of the outer wall decorative material 32 in the Y direction. Here, since the upper wall 54 extends below the covering member 36, the covering member 36 is supported by the upper wall 54 when the covering member 36 is lowered in the Z direction. be able to.

Furthermore, in the base drainer 30, the outer wall 55 covers the inner wall 53 when viewed from the Y direction. In other words, the area of the outer wall 55 when viewed in the Y direction is larger than the area of the inner wall 53 . The inner wall 53 and the outer wall 55 are integrated as the drainer body portion 52 . Therefore, when the engaging portion 60 and the engaged portion 46 are engaged by applying an external force to the inner wall 53, even if the area of the inner wall 53 is small and it is difficult to apply the external force, By applying an external force to the outer wall 55 having a large area, the external force can be applied to the engaging portion 60 . By having the outer wall 55 in this manner, a large external force can be applied to the engaging portion 60 .

Note that the present invention is not limited to the above embodiments.

The bellows member 86 is an example of an elastic member and an elastic member. The bellows member 86 may be made of either rubber or resin. By using the bellows member 86, compared with the case of using the rubber plate 41, it becomes easier to deform the side where the stretchable portion in the Y direction is contracted (the side where the covering member 36 approaches the fixing member 34). Both ends of the bellows member 86 in the Y direction may be attached to the fixing member 34 and the covering member 36 by adhesion or fitting.

<Fourth modification>
As shown in FIG. 9C, in the exterior wall decorative member 32, the fixing member 34 and the covering member 36 may be connected by an extendable rod 88 that is extendable in the Y direction. The telescopic rod 88 is an example of a telescopic part. Also, the telescopic rod 88 may be made of either metal or resin. As an example, the telescopic rod 88 is composed of three cylindrical members 88A, 88B and 88C having different outer diameters. is configured as a member whose detachment is restricted. Both ends of the telescopic rod 88 in the Y direction may be attached to the fixing member 34 and the covering member 36 by adhesion or fitting.
