Modes for Carrying Out the Invention

[0010] Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative examples.

[0011] First, with reference to FIGS. 1 to 3, the configuration of an exterior building material support structure according to some embodiments will be described. Hereinafter, the exterior building material support structure may be abbreviated as the "support structure". FIG. 1 is a cross-sectional view of an exterior building material support structure in the width direction of an exterior building material according to an embodiment. FIG. 2 is a schematic view showing the state of a waterproof sealing material before and after deformation according to an embodiment. Note that the general shape of the waterproof sealing material before deformation is drawn with a two-dot chain line, and the general shape of the waterproof sealing material after deformation is drawn with a solid line. FIG. 3 is a cross-sectional view of an exterior building material support structure according to an embodiment, and is a cross-sectional view obtained by cutting the exterior building material support structure shown in FIG. 1 along line A-A.

[0012] The exterior building material support structure 1 is for supporting an exterior building material 2 that partitions the inside and outside of a building 9. As shown in FIG. 1, the exterior building material 2 includes an outdoor side surface 2a facing the outside of the building 9 and an indoor side surface 2b facing the inside of the building 9. In the embodiment shown in FIG. 1, the exterior building material 2 is a lightweight foamed concrete building material (ALC). In other embodiments not shown, the exterior building material 2 may be, for example, a sash or an extruded cement board (ECP).

[0013] In some embodiments, as shown in FIGS. 1 and 3, the exterior building material support structure 1 includes a support concrete 3, an angle member 4 extending along the width direction X2 of the exterior building material 2 on the support concrete 3, and a waterproof sealant 5. The waterproof sealant 5 is installed in a state of being sandwiched between the upper surface 31 of the support concrete 3 and the lower surface (the lower surface 42c of the first plate portion 42 described later) of the angle member 4 in the height direction X1 of the exterior building material 2. Note that the support concrete 3 may be, for example, slab concrete constituting the building 9 or beam concrete.

[0014] As shown in FIG. 1, the angle member 4 includes a first plate portion 42 extending along the thickness direction X3 of the exterior building material 2 and a second plate portion 44 extending along the indoor side surface 2b of the exterior building material 2. The second plate portion 44 is connected to the first plate portion 42 and extends along the height direction X1.

[0015] As shown in FIG. 1, the first plate portion 42 includes an outdoor end portion 42A on the outdoor side in the thickness direction X3 and an indoor end portion 42B on the indoor side in the thickness direction X3. In the embodiment shown in FIG. 1, the first plate portion 42 is connected to the second plate portion 44 at the indoor end portion 42B. That is, the angle member 4 has an L-shaped cross-sectional shape when viewed from the width direction X2. Thus, the angle member 4 may be, for example, an equal-leg angle steel or an unequal-leg angle steel. In other embodiments (not shown), the first plate portion 42 may be connected to the second plate portion 44 at a position between the outdoor end portion 42A and the indoor end portion 42B in the thickness direction X3. That is, the angle member 4 may have a T-shaped cross-sectional shape when viewed from the width direction X2.

[0016] In some embodiments, the outdoor end portion 42A of the first plate portion 42 has an end face 42a in the thickness direction X3. The end face 42a of the first plate portion 42 is located on the indoor side of the outdoor side surface 2a of the exterior building material 2 and on the outdoor side of the indoor side surface 2b when viewed from the height direction X1. In the embodiment shown in FIG. 1, when the position of the indoor side surface 2b of the building exterior material 2 in the thickness direction X3 is set to 0% and the position of the outdoor side surface 2a is set to 100%, the end surface 42a of the first plate portion 42 is located at a thickness direction position of 40% to 60%. In other embodiments (not shown), the end surface 42a of the first plate portion 42 may be located at the same position as the outdoor side surface 2a of the building exterior material 2 in the thickness direction X3.

[0017] At least a part of the first plate portion 42 is located between the upper surface 31 of the support concrete 3 and the lower surface 2c of the building exterior material 2 in the height direction X1 as described above. Therefore, the first plate portion 42 transmits the load received from the building exterior material 2 located above the first plate portion 42 to the support concrete 3 via the waterproof sealing material 5. That is, the first plate portion 42 supports the building exterior material 2 in the height direction X1.

[0018] In the embodiments shown in FIGS. 1 and 3, the first plate portion 42 supports the building exterior material 2 via the filler 7. That is, the filler 7 is located between the first plate portion 42 and the lower surface 2c of the building exterior material 2 in the height direction X1. In the embodiments illustrated in FIGS. 1 and 3, the filler 7 is a refractory material. The type of the refractory material is not particularly limited, and for example, it may be rock wool. In other embodiments (not shown), the first plate portion 42 directly supports the building exterior material 2. That is, the first plate portion 42 is arranged to directly contact the lower surface 2c of the building exterior material 2.

[0019] The waterproof sealing material 5 installed on the upper surface 31 of the supporting concrete 3 is installed in a state of being sandwiched between the upper surface 31 of the supporting concrete 3 and the lower surface 42c of the first plate portion 42, as shown in FIGS. 1 to 3. That is, the waterproof sealing material 5 is installed in a deformed state under the load in the height direction X1 from the first plate portion 42. More specifically, as shown in FIG. 2, the waterproof sealing material 5 viewed from the width direction X2 has a cross-sectional shape as illustrated by the two-dot chain line before the first plate portion 42 is installed. After that, when the first plate portion 42 is installed, the cross-sectional shape of the waterproof sealing material 5 deforms so that the height becomes lower and it spreads in the thickness direction X3, as shown by the solid line in FIG. 2. Note that the waterproof sealing material 5 is not particularly limited, and for example, it may be butyl rubber.

[0020] According to the above configuration, it is possible to prevent water from entering the room from between the upper surface 31 of the supporting concrete 3 and the lower surface 42c of the first plate portion 42 of the angle member 4. Therefore, it is possible to effectively prevent water from entering the room from the outside.

[0021] In the embodiment shown in FIGS. 1 to 3, the lower surface 42c of the first plate portion 42 is a flat surface extending along the upper surface 31 of the supporting concrete 3. In other embodiments (not shown), a recess may be provided in the lower surface 42c of the first plate portion 42. At this time, the depth of the recess in the lower surface 42c is shallower than the height of the waterproof sealing material 5. By installing the first plate portion 42 so that the waterproof sealing material 5 is received in the recess of the lower surface 42c, the waterproof sealing material 5 is sandwiched between the supporting concrete 3 and the first plate portion 42, and the positioning of the first plate portion 42 in the thickness direction X3 can be easily performed.

[0022] In the embodiment shown in FIG. 1, the first plate portion 42 of the angle member 4 is fixed to the support concrete 3 by the anchor 8. The shaft portion 82 of the anchor 8 penetrates the first plate portion 42 along the height direction X1, and is fixed in the hole 33 provided in the support concrete 3 or in the hole 33 formed by driving the shaft portion 82 into the support concrete 3. The head portion 84 of the anchor 8 abuts against the upper surface 42d of the first plate portion 42 and fixes the first plate portion 42 in the height direction X1. Note that the type of the anchor 8 is not particularly limited, and it may be a metal-based anchor or an adhesive anchor.

[0023] According to the above configuration, since the waterproof sealing material 5 is more reliably sandwiched between the upper surface 31 of the support concrete 3 and the lower surface 42c of the first plate portion 42, the waterproof property between the support concrete 3 and the first plate portion 42 can be improved.

[0024] In the embodiment shown in FIG. 1, the waterproof sealing material 5 is located on the outdoor side of the anchor 8. That is, the indoor-side end face 5b of the waterproof sealing material 5 in the thickness direction X3 is located on the outdoor side of the anchor 8 in the thickness direction X3.

[0025] According to the above configuration, it is difficult for the water that has entered between the support concrete 3 and the first plate portion 42 to reach the anchor 8. Therefore, deterioration of the anchor 8 can be prevented, and the durability of the support structure 1 can be improved.

[0026] In the embodiment shown in FIG. 3, the waterproof sealing material 5 includes a first portion 52 extending along the width direction X2 and a second portion 56 rising from an end portion 54 of the first portion 52 in the width direction X2.

[0027] As described above, the first portion 51 is installed in a state of being sandwiched between the upper surface 31 of the support concrete 3 and the lower surface 42c of the first plate portion 42.

[0028] As shown in FIG. 3, the second portion 56 extends along the side surface 202 of the structure 200 adjacent to the support structure 1. That is, the second portion 56 extends along the height direction X1. Note that the structure 200 is not particularly limited and may be, for example, the outer wall or column of the building 9.

[0029] According to the above configuration, even if water accumulates outside the building 9, it is possible to more effectively prevent water from entering the building from the outside. Therefore, the waterproof performance of the support structure 1 can be further improved.

[0030] In the embodiment shown in FIG. 3, the end portion 54 of the first portion 52 abuts against the side surface 202 of the structure 200 adjacent to the exterior building material support structure 1. Also, at least a part of the second portion 56 is located between the first plate portion 42 of the angle member 4 and the side surface 202 of the structure 200 in the width direction X2.

[0031] As shown in FIG. 3, it is preferable that the height h of the second portion 56 satisfies the condition of 0.25 ≦ h / H ≦ 1 when the distance between the lower surface 2c of the exterior building material 2 and the upper surface 31 of the support concrete 3 is H. By the second portion 56 satisfying the above conditions, even if water accumulates outside the building 9, it is possible to more reliably prevent water from entering the building from the outside.

[0032] In the embodiment shown in FIG. 1, the exterior building material support structure 1 may include a plate member 102 and bolts 104 for fixing the plate member 102 to the indoor side surface 2b of the exterior building material 2. The plate member 102 is configured to sandwich the upper end portion 44D of the second plate portion 44 located above the height position of the lower surface 2c of the exterior building material 2 between the plate member 102 and the exterior building material 2 in the thickness direction X3. Therefore, the exterior building material 2 is fixed in the thickness direction X3.

[0033] Subsequently, with reference to FIGS. 1, 4, and 5, a further configuration of the exterior building material support structure according to several embodiments will be described. FIG. 4 is a view showing an embodiment in the region B shown in FIG. 1, and is a partially enlarged view of a cross-sectional view of the exterior building material support structure. FIG. 5 is a view showing another embodiment in the region B shown in FIG. 1, and is a partially enlarged view of a cross-sectional view of the exterior building material support structure.

[0034] In some embodiments, as shown in FIGS. 1, 4, and 5, the exterior building material support structure 1 (1A, 1B) further includes at least one waterproof seal 20 (22, 24) installed on the outdoor side of the angle member 4. That is, the indoor side surface 20b (22b, 24b) of the waterproof seal 20 (22, 24) is located on the outdoor side of the end surface 42a of the first plate portion 42. Further, the waterproof seal 20 (22, 24) extends along the width direction X2 between the support concrete 3 and the exterior building material 2. Note that the waterproof seal 20 (22, 24) is not particularly limited and may be polyurethane or silicone.

[0035] According to the above configuration, it is difficult for water to enter between the support concrete 3 and the first plate portion 42. Therefore, the waterproof property of the exterior building material support structure 1 (1A, 1B) can be further enhanced.

[0036] In the embodiments shown in FIGS. 1, 4, and 5, the indoor side surface 22b (20b) of the waterproof seal 22 (20) is in contact with the end surface 42a of the first plate portion 42. Therefore, even if water intrudes from between the exterior building material 2 and the waterproof seal 20, it is difficult for water to intrude between the angle member 4 and the support concrete 3. Further, the indoor side surface 22b (20b) of the waterproof seal 22 (20) may be in contact with the end surface 5a of the waterproof seal material 5.

[0037] In the embodiments shown in FIGS. 1, 4, and 5, the lower surface 20c (22c, 24c) of the waterproof seal 20 (22, 24) is adhered to the upper surface 31 of the support concrete 3. Similarly, the upper surface 20d (22d, 24d) of the waterproof seal 20 (22, 24) is adhered to the lower surface 2c of the exterior building material 2. Therefore, it is difficult for water to enter between the support concrete 3 and the first plate portion 42.

[0038] In the embodiments shown in FIGS. 1, 4, and 5, the waterproof seal 20 includes a pair of waterproof seals 22 and 24 that are arranged side by side in the thickness direction X3. That is, one waterproof seal 22 and the other waterproof seal 24 are separate from each other and are arranged side by side in the thickness direction X3. One waterproof seal 22 is installed between the end face 42a of the first plate portion 42 and the indoor side surface 24b of the other waterproof seal 24 in the thickness direction X3. That is, the other waterproof seal 24 is installed on the outdoor side of the outdoor side surface 22a of one waterproof seal 22. Further, one waterproof seal 22 and the other waterproof seal 24 may be arranged in contact with each other or separated from each other in the thickness direction X3. Note that the pair of waterproof seals 22 and 24 may be made of the same material or different materials from each other.

[0039] According to the above configuration, when lateral shaking such as an earthquake occurs, the possibility that the waterproof seals 22 and 24 pull on each other and break can be reduced. Therefore, the durability of the exterior building material support structure 1 (1A, 1B) can be enhanced.

[0040] In an embodiment not shown, the pair of waterproof seals 22 and 24 are arranged so as not to adhere to each other. That is, the pair of waterproof seals 22 and 24 are not adhered by an adhesive or the like.

[0041] In the embodiments shown in FIGS. 1 and 4, the pair of waterproof seals 22 and 24 are arranged such that one waterproof seal 22 is separated from the other waterproof seal 24. That is, the outdoor side surface 22a of one waterproof seal 22 and the indoor side surface 24b of the other waterproof seal 24 are arranged with a distance X therebetween in the thickness direction X3. At this time, a gap G is formed between the pair of waterproof seals 22 and 24.

[0042] According to the above configuration, when lateral shaking such as an earthquake occurs, the possibility that the waterproof seals 22 and 24 rub against each other and are damaged can be reduced. Thus, the durability of the exterior building material support structure 1 (1A) can be further enhanced.

[0043] Incidentally, the distance X between the outdoor side surface 22a of one waterproof seal 22 and the indoor side surface 24b of the other waterproof seal 24 is preferably 10 mm or less. If the distance X is too large, the gap G may become a water retention location. Since the water retained in the gap G may cause mold growth and deterioration of the surrounding members, by setting the distance X to 10 mm or less, the possibility of mold growth and deterioration of the surrounding members can be suppressed.

[0044] In the embodiment shown in FIG. 5, the exterior building material support structure 1B further includes a backup material 30 installed between the pair of waterproof seals 22 and 24. That is, the backup material 30 is installed between the outdoor side surface 22a of one waterproof seal 22 and the indoor side surface 24b of the other waterproof seal 24.

[0045] According to the above configuration, when lateral shaking such as an earthquake occurs, the possibility that the waterproof seals 22 and 24 rub against each other and are damaged can be reduced. Therefore, the durability of the exterior building material support structure 1(1B) can be further enhanced.

[0046] In the embodiment shown in FIG. 5, the backup material 30 is made of a material that is difficult to adhere to both of the pair of waterproof seals 22 and 24. Therefore, the outdoor side surface 30a of the backup material 30 and the indoor side surface 24b of the waterproof seal 24 are not adhered to each other. Similarly, the indoor side surface 30b of the backup material 30 and the outdoor side surface 22a of the waterproof seal 22 are not adhered to each other. Therefore, when lateral shaking such as an earthquake occurs, the waterproof seals 22 and 24 can be pulled against each other through the backup material 30, reducing the possibility that the waterproof seals 22 and 24 break. The material of the backup material 30 is not particularly limited, and for example, it may be polyethylene. Note that the backup material 30 may be a sponge in which air bubbles are formed inside the backup material 30. Since the sponge as the backup material 30 has cushioning properties, the backup material 30 in a compressed state can be installed between the upper surface 31 of the support concrete 3 and the lower surface 2c of the exterior building material 2. At this time, since the restoring force of the backup material 30 acts on the support concrete 3 and the exterior building material 2 along the height direction X1, the backup material 30 can be easily fixed.

[0047] In some embodiments, as shown in FIGS. 1, 4, and 5, the exterior building material support structure 1 (1A, 1B) further includes a waterproof film 60 that extends along the height direction X1 of the exterior building material 2 from the upper surface 31 of the support concrete 3 on the outdoor side. The waterproof film 60 includes a vertical attachment portion 62 that is attached to the outdoor side surface 2a of the exterior building material 2.

[0048] According to the above configuration, the gap between the exterior building material 2 and the support concrete 3 can be closed. Therefore, the waterproof property of the exterior building material support structure 1 (1A, 1B) can be further enhanced.

[0049] In the embodiments shown in FIGS. 1, 4, and 5, the vertical attachment portion 62 has a first surface 62b that faces the outdoor side surface 2a of the exterior building material 2, and is attached to the outdoor side surface 2a of the exterior building material 2 on the first surface 62b.

[0050] In the embodiments shown in FIGS. 1, 4, and 5, the vertical attachment portion 62 is located below the first surface 62b and further includes a second surface 62c that faces the waterproof seal 24 (20). The vertical attachment portion 62 is attached to the outdoor side surface 24a (20a) of the waterproof seal 24 (20) on the second surface 62c. By attaching the vertical attachment portion 62 to the exterior building material 2 and the waterproof seal 24 (20), water intrusion between the exterior building material 2 and the waterproof seal 24 (20), and between the waterproof seal 24 (20) and the support concrete 3 can be more effectively prevented.

[0051] In some embodiments, as shown in FIGS. 1, 4, and 5, the waterproof film 60 further includes a horizontal attachment portion 64 that extends outward from the lower end 62C of the vertical attachment portion 62 and is attached to the upper surface 31 of the support concrete 3.

[0052] According to the above configuration, the intrusion of water along the upper surface 31 of the support concrete 3 can be more effectively prevented. Therefore, the waterproof performance of the exterior building material support structure 1 (1A, 1B) can be further improved.

[0053] Note that the waterproof film 60 may be a sheet-shaped sealing material or a film formed by solidifying a liquid waterproof agent. Further, since the waterproof film 60 is exposed to sunlight and rainfall, high waterproof performance and weather resistance are required. Therefore, the waterproof film 60 is preferably, for example, a urethane-based coating film.

[0054] Summarizing the characteristic configurations of the exterior building material support structure 1 (1A, 1B) according to the above-described several embodiments, it is as follows.

[0055] [1] The exterior building material support structure (1 (1A, 1B)) according to several embodiments is an exterior building material support structure (1 (1A, 1B)) that supports an exterior building material (2) partitioning the inside and outside of a building (9), a support concrete (3), an angle member (4) extending along the width direction (X2) of the exterior building material (2) on the support concrete (3), the angle member (4) including a first plate portion (42) extending in the thickness direction (X3) of the exterior building material (2) and supporting the exterior building material (2), and a second plate portion (44) extending along the indoor side surface (2b) of the exterior building material (2), a waterproof sealing material (5) extending along the width direction (X2) on the support concrete (3), the waterproof sealing material (5) being installed in a state of being sandwiched between the upper surface (31) of the support concrete (3) and the lower surface (42c) of the first plate portion (42), and comprising.

[0056] According to the configuration of [1] above, since the waterproof sealing material (5) is installed in a sandwiched state between the upper surface (31) of the support concrete (3) and the lower surface (42c) of the first plate portion (42) of the angle member (4), it is possible to prevent water from entering the room from between the upper surface (31) of the support concrete (3) and the lower surface (42c) of the first plate portion (42) of the angle member (4). Therefore, it is possible to effectively prevent water from entering from the outside to the inside while reducing the construction man-hours of the exterior building material support structure.

[0057] [2] In some embodiments, in the configuration of [1] above, The first plate portion (42) of the angle member (4) is fixed to the support concrete (3) by an anchor (8).

[0058] According to the configuration of [2] above, since the first plate portion (42) is fixed to the support concrete (3) by an anchor (8), the waterproof sealing material (5) is more reliably sandwiched between the upper surface (31) of the support concrete (3) and the lower surface (42c) of the first plate portion (42). Therefore, the waterproof property between the support concrete (3) and the first plate portion (42) can be improved.

[0059] [3] In some embodiments, in the configuration of [2] above, The waterproof sealing material (5) is located on the outdoor side of the anchor (8).

[0060] According to the configuration of [3] above, since the waterproof sealing material (5) is installed on the outdoor side of the anchor (8), it is difficult for water that has entered between the support concrete (3) and the first plate portion (42) from the outside to reach the anchor (8). Therefore, deterioration of the anchor (8) can be prevented, and the durability of the exterior building material support structure (1(1A, 1B)) can be improved.

[0061] [4] In some embodiments, in any of the configurations of [1] to [3] above, The waterproof sealing material (5) is A first portion (52) that extends along the width direction (X2) and is installed in a state of being sandwiched between the upper surface (31) of the support concrete (3) and the lower surface (42c) of the first plate portion (42); A second portion (56) that rises from an end portion (54) of the first portion (52) in the width direction (X2) and extends along the side surface (202) of the adjacent structure (200); It includes.

[0062] According to the configuration of [4] above, since the waterproof sealing material (5) includes the second portion (56) that extends along the side surface (202) of the adjacent structure (200), even if water accumulates outdoors in the building (9), it is possible to more effectively prevent water from entering from the outside to the inside. Therefore, the waterproof performance of the exterior building material support structure (1(1A, 1B)) can be further improved.

[0063] [5] In some embodiments, in any of the configurations of [1] to [4] above, the exterior building material support structure (1(1A, 1B)) Further includes at least one waterproof seal (20(22, 24)) that extends along the width direction (X2) between the support concrete (3) and the exterior building material (2) and is installed on the outdoor side of the angle member (4).

[0064] According to the configuration of [5] above, since at least one waterproof seal (20(22, 24)) is installed on the outdoor side of the angle member (4), it is difficult for water to enter between the support concrete (3) and the first plate portion (42). Therefore, the waterproof performance of the exterior building material support structure (1(1A, 1B)) can be further enhanced.

[0065] [6] In some embodiments, in the configuration of [5] above, At least one waterproof seal (20) includes a pair of waterproof seals (22, 24) arranged side by side in the thickness direction (X3).

[0066] When a plurality of waterproof seals are adhesively arranged with each other in the thickness direction (X3), there is a risk that the waterproof seals may pull on each other due to lateral shaking such as an earthquake. If the waterproof seals pull on each other, the waterproof seals may break, and the waterproof performance of the exterior building material support structure may deteriorate. In this regard, according to the configuration of [6] above, since the pair of waterproof seals (22, 24) are arranged side by side in the thickness direction (X3), when lateral shaking such as an earthquake occurs, the possibility that the waterproof seals (22, 24) pull on each other and break can be reduced. Therefore, the durability of the exterior building material support structure (1(1A, 1B)) can be enhanced.

[0067] [7] In some embodiments, in the configuration of [6] above, One of the pair of waterproof seals (22, 24) is installed at a distance from the other waterproof seal (24).

[0068] According to the configuration of [7] above, since one of the waterproof seals (22) is installed at a distance from the other waterproof seal (24), the pair of waterproof seals (22, 24) do not contact each other. Therefore, when lateral shaking such as an earthquake occurs, the possibility that the waterproof seals (22, 24) rub against each other and are damaged can be reduced. Therefore, the durability of the exterior building material support structure (1(1A)) can be further enhanced.

[0069] [8] In some embodiments, in the configuration of [6] above, the exterior building material support structure (1(1B)) further includes a backup material (30) installed between the pair of waterproof seals (22, 24).

[0070] According to the configuration of [8] above, since the backup material (30) is installed between the pair of waterproof seals (22, 24), the pair of waterproof seals (22, 24) do not contact each other. Therefore, when lateral shaking such as an earthquake occurs, the possibility that the waterproof seals (22, 24) rub against each other and are damaged can be reduced. Therefore, the durability of the exterior building material support structure (1(1B)) can be further enhanced.

[0071] [9] In some embodiments, in any of the configurations of [1] to [8] above, the exterior building material support structure (1 (1A, 1B)) is a waterproof film (60) extending along the height direction (X1) of the exterior building material (2) from the upper surface (31) of the support concrete (3) on the outdoor side, and further includes a vertical attachment portion (62) attached to the outdoor side surface (2a) of the exterior building material (2).

[0072] According to the configuration of [9] above, since the vertical attachment portion (62) of the waterproof film (60) is attached to the outdoor side surface (2a) of the exterior building material (2), the gap between the exterior building material (2) and the support concrete (3) can be blocked. Therefore, the waterproof property of the exterior building material support structure (1 (1A, 1B)) can be further enhanced.

[0073]

[10] In some embodiments, in the configuration of [9] above, the waterproof film (60) further includes a horizontal attachment portion (64) extending outward from the lower end (62C) of the vertical attachment portion (62) and attached to the upper surface (31) of the support concrete (3).

[0074] According to the configuration of

[10] above, since the horizontal attachment portion (64) extends outward from the lower end (62C) of the vertical attachment portion (62), the intrusion of water along the upper surface (31) of the support concrete (3) can be more effectively prevented. Therefore, the waterproof property of the exterior building material support structure (1 (1A, 1B)) can be further improved.

[0075] As described above, several embodiments of the present invention have been described. Of course, modifications may be made to the above-described embodiments without departing from the spirit of the present invention.

[0076] In this specification, expressions indicating relative or absolute arrangements such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "concentric", or "coaxial" not only strictly represent such arrangements, but also represent states where there are tolerances, or relative displacements with angles and distances that can achieve the same function. For example, expressions indicating that things such as "identical", "equal", and "homogeneous" are in an equal state not only strictly represent an equal state, but also represent states where there are tolerances, or differences that can achieve the same function. Also, in this specification, expressions representing shapes such as a square shape or a cylindrical shape not only represent shapes such as a square shape or a cylindrical shape in a geometrically strict sense, but also represent shapes including uneven portions, chamfered portions, etc. within a range where the same effect can be obtained. Also, in this specification, the expressions "comprising", "including", or "having" for a component are not exclusive expressions that exclude the existence of other components.
