Summary of the Invention

Problems to be Solved by the Invention

[0004] In the decorative skirts described in Patent Document 1 and Patent Document 2, in addition to the design function of hiding the joints of the outer wall and the waterproof sheet, they have a waterproof function by pressing the waterproof sheet. Generally, the surface to which the waterproof sheet is attached needs to be flat. In order to press and hide the waterproof sheet attached to the flat surface by the decorative skirt, the vertical width of the decorative skirt, that is, the apparent part may become wider.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a decorative girth that has both a design function and a waterproof function while achieving a small visible part, and a building equipped with this decorative girth. [Means for solving the problem]

[0006] The decorative girder in the first embodiment includes a decorative flashing member that conceals more than half of the horizontal joints of adjacent exterior wall panels above and below, and a waterproof flashing member that is located below the decorative flashing member, is composed of a separate part from the decorative flashing member, and has a waterproof function against water spraying up on the decorative surface of the exterior wall panel located below.

[0007] According to the first aspect, the decorative girth includes a decorative drainage member having a design function and a waterproof drainage member that is a separate part from the decorative drainage member and has a waterproof function against water splashing up. In this way, by making the decorative girth into separate parts for each function, each part can be made smaller while still fulfilling its respective role. This allows the visible part to be made smaller while still having both a design function and a waterproof function.

[0008] The decorative girder in the second aspect, in the configuration described in the first aspect, comprises a waterproof sheet whose upper end is attached to the back surface of the exterior wall panel located on the upper side and whose lower end extends between the decorative girder member and the waterproof girder member, and which is fixed to the main body of the building together with the decorative girder member.

[0009] Generally, waterproof sheets are fixed to exterior wall panels etc. with double-sided tape etc. According to the second aspect, the waterproof sheet is fixed to the building body together with the decorative flashing member, so that, for example, when the decorative flashing member is fixed to the building body with screws etc., the waterproof sheet is also fixed with screws etc., which improves the adhesion of the waterproof sheet to the application surface.

[0010] The decorative girder in the third aspect, in the configuration described in the second aspect, has a drainage channel on the design surface side of the exterior wall panel between the design drainage member and the waterproof drainage member to drain water that has seeped in through the waterproof sheet.

[0011] According to the third aspect, a drainage channel is provided between the decorative drainage member and the waterproof drainage member on the decorative surface side of the exterior wall panel to drain water that has seeped in through the waterproof sheet. Therefore, for example, even if only a small amount of water seeps in through the fixing part of the waterproof sheet, the seeped water can be discharged from the drainage channel.

[0012] The decorative girder in the fourth aspect is configured as described in any one of the first to third aspects, in which the waterproof drainage member is integrally provided with a water-stopping material that is arranged on the edge surface of the exterior wall panel located below.

[0013] According to the fourth aspect, since the waterproof dripping member is integrally provided with the water-stopping material, it is possible to reduce the use of water-stopping tape that has conventionally been affixed to the edge surface of the exterior wall panel.

[0014] The decorative girder of the fifth aspect, in the configuration described in the first aspect, is provided with a waterproof sheet whose upper end is attached to the back surface of the exterior wall panel located on the upper side and whose lower end is extended between the decorative surface of the exterior wall panel located on the lower side and the waterproof drainage member.

[0015] According to the fifth aspect, the lower end of the waterproof sheet is extended between the design surface of the exterior wall panel and the waterproof drainage member, so that the waterproof drainage member can hold the lower end of the waterproof sheet against the design surface of the exterior wall panel. This improves the adhesion of the waterproof sheet to the design surface of the exterior wall panel.

[0016] The decorative girth according to the sixth aspect has the configuration described in the first or fifth aspect, in which the decorative drainage member and the waterproof drainage member are provided with engagement means for engaging with each other.

[0017] According to the sixth aspect, the decorative drainage member and the waterproof drainage member are provided with engaging means for engaging with each other, so that the decorative drainage member and the waterproof drainage member can be integrated by engaging the decorative drainage member and the waterproof drainage member with each other via the engaging means.

[0018] A decorative girth according to a seventh aspect is configured as described in any one of the first, fifth and sixth aspects, wherein the waterproof drainage member is configured from a sheet metal member.

[0019] Conventional decorative girths are provided with a surface material having a decorative surface and a fireproof material arranged to hold the waterproof sheet against the exterior wall panel, so that the thickness in the direction of the interior and exterior of the building is thick. According to the seventh aspect, the waterproof girth is made of a sheet metal material, so that the thickness can be reduced. Since the waterproof girth is held against the exterior wall panel by the waterproof girth, the decorative girth does not need to hold the waterproof sheet against the exterior wall panel. For this reason, the decorative girth can be made thinner by simply arranging a noncombustible material in the horizontal joints of the exterior wall panels adjacent above and below. In this way, the thickness of both the waterproof girth and the decorative girth can be reduced, so that the overall thickness of the decorative girth can be reduced.

[0020] A building according to an eighth aspect includes the decorative girth structure according to any one of the first to seventh aspects.

[0021] According to the eighth aspect, it is possible to enjoy the effects of the decorative tensioner according to any one of the first to seventh aspects. Effect of the Invention

[0022] As described above, the decorative girth according to the first aspect has the excellent effect of realizing a miniaturized visible portion while having both a design function and a waterproof function.

[0023] The decorative girth according to the second aspect has the excellent effect of improving adhesion to the application surface of the waterproof sheet.

[0024] The decorative girth according to the third aspect has the excellent effect of enabling water that has seeped in through the fixing parts of the waterproof sheet, etc., to be discharged through the drainage channel.

[0025] The decorative girth according to the fourth aspect has the excellent effect of making it possible to reduce the need for waterproof tape that has conventionally been affixed to the edge surface of an exterior wall panel.

[0026] The decorative girth according to the fifth aspect has the excellent effect of improving the adhesion of the waterproof sheet to the decorative surface of the exterior wall panel.

[0027] The decorative girth according to the sixth aspect has the excellent effect of integrating a decorative drainage member and a waterproof drainage member.

[0028] The decorative drum strap according to the seventh aspect has the excellent effect of reducing the overall thickness of the decorative drum strap.

[0029] The building according to the eighth aspect can enjoy the effects of the decorative girder panels according to the first to seventh aspects. [Brief description of the drawings]

[0031] First Embodiment Hereinafter, the decorative girth 30 according to the first embodiment will be described with reference to Figs. 1 to 3. Fig. 1 shows a schematic front view of the structure of a building 10 to which the decorative girth 30 according to the first embodiment is applied. Fig. 2 shows a vertical cross-sectional view of the exterior wall panel 20 including the decorative girth 30, and Fig. 3 shows an exploded enlarged cross-sectional view of the decorative girth 30 in Fig. 2. In each drawing, the height direction of the building 10 is described as the up-down direction. In this embodiment, the building 10 is an ordinary house composed of a two-story unit-type building as an example, and is composed of a plurality of building units connected together. The building 10 can also be composed of a single building unit. In addition, as each building unit, for example, a configuration (not shown) in which four pillars are erected between a ceiling frame and a floor frame assembled in a rectangular frame shape can be adopted, but this is not limited thereto, and other box-shaped frame structures may also be used.

[0032] As shown in Fig. 1, a building 10 is constructed to have multiple floors (two floors as an example) by using a plurality of building units 12 placed on a foundation (not shown). Each building unit 12 has a rectangular parallelepiped shape, and the building units 12 are stacked in the vertical direction of the building to form a lower floor (first floor in this embodiment) and an upper floor (second floor in this embodiment) of the building 10. In this embodiment, the building unit 12 that constitutes the first floor is referred to as a lower floor unit 12A, and the building unit 12 that constitutes the second floor is referred to as an upper floor unit 12B.

[0033] The lower floor unit 12A and the upper floor unit 12B are attached with exterior wall panels 20. In this embodiment, a lower exterior wall panel 20A is attached as the exterior wall panel 20 to the lower floor unit 12A, and an upper exterior wall panel 20B is attached as the exterior wall panel 20 to the upper floor unit 12B.

[0034] Furthermore, at a height position of the exterior wall panels 20 of the building 10 corresponding to the boundary between the first and second floors of the building 10, a long decorative girth 30 that conceals the gap between the lower exterior wall panel 20A and the upper exterior wall panel 20B from the outside is disposed approximately around the entire periphery of the building 10. In other words, the decorative girth 30 conceals the horizontal joint formed along the boundary between the lower exterior wall panel 20A and the upper exterior wall panel 20B.

[0035] As shown in Fig. 2, the exterior wall panels 20, i.e., the lower exterior wall panel 20A and the upper exterior wall panel 20B, each include an exterior wall surface material 22 and a plurality of decorative surface materials 24 arranged along the outer peripheral surface of the exterior side (outside of the room) of the building of the exterior wall surface material 22. The decorative surface material 24 is formed in a rectangular plate shape using an exterior material such as a siding board made of a material with excellent weather resistance. The exterior side (outside of the room) of the decorative surface material 24 is a decorative surface 24A with unevenness or the like formed thereon.

[0036] The lower exterior wall panel 20A is attached to a lower floor exterior wall frame 13 arranged on the building inward side of the lower exterior wall panel 20A by fasteners not shown. The lower floor exterior wall frame 13 is arranged at each end of the exterior wall surface material 22 of the lower exterior wall panel 20A in the vertical direction of the building, and is composed of horizontal frames 14 that are arranged at the ends in the vertical direction of the building of the exterior wall surface material 22 of the lower exterior wall panel 20A and extend with the horizontal direction along the ends as the longitudinal direction, and vertical frames not shown that connect the horizontal frames 14 at the ends in the vertical direction of the building of the exterior wall surface material 22 of the lower exterior wall panel 20A in the vertical direction of the building.

[0037] The horizontal frame 14 has an approximately U-shaped cross section perpendicular to the longitudinal direction, and is formed by the outer vertical wall portion 14A, the inner vertical wall portion 14B, and the bottom wall portion 14C that connects one end of the outer vertical wall portion 14A in the vertical direction of the building with the corresponding one end of the inner vertical wall portion 14B in the vertical direction of the building in the approximately horizontal direction. The horizontal frame 14 provided at the position corresponding to the upper end portion 22A of the exterior wall surface material 22 of the lower exterior wall panel 20A is arranged with the cross-sectional opening open toward the upper side of the building. The inner vertical wall portion 14B is formed so that the length from the bottom wall portion 14C is shorter than that of the outer vertical wall portion 14A.

[0038] The ceiling girder 40A, which constitutes part of the lower floor unit 12A where the inner vertical wall portion 14B of the horizontal frame 14 and the inner vertical wall portion 14B abut, each has a through hole (not shown) that penetrates in the thickness direction of the plate, and by inserting bolts 18A from the ceiling girder 40A side into these through holes and fastening them with nuts 18B from the horizontal frame 14 side, the horizontal frame 14 and ultimately the lower floor exterior wall frame 13 are fixed to the ceiling girder 40A.

[0039] The upper exterior wall panel 20B is attached to an upper floor exterior wall frame 15 arranged on the building 10 side of the upper exterior wall panel 20B by fasteners (not shown). The upper floor exterior wall frames 15 are arranged at the ends of the exterior wall surface material 22 of the upper exterior wall panel 20B in the vertical direction of the building, respectively, and are composed of horizontal frames 16 extending with the horizontal direction along the ends as the longitudinal direction, and vertical frames (not shown) that connect the horizontal frames 16 at the ends of the exterior wall surface material 22 of the upper exterior wall panel 20B in the vertical direction of the building in the vertical direction of the building.

[0040] The horizontal frame 16, like the horizontal frame 14 in the lower floor exterior wall frame 13 of the lower floor unit 12A constituting the first floor of the building 10, is formed with an approximately U-shaped cross section perpendicular to the longitudinal direction by an outer vertical wall portion 16A, an inner vertical wall portion 16B, and a bottom wall portion 16C that connects one end of the outer vertical wall portion 16A in the vertical direction of the building and one end of the corresponding inner vertical wall portion 16B in the vertical direction of the building in the approximately horizontal direction. In addition, the horizontal frame 16 provided at a position corresponding to the lower end portion 22B of the exterior wall surface material 22 of the upper exterior wall panel 20B is arranged with the cross-sectional opening open toward the lower side of the building. In addition, the inner vertical wall portion 16B is formed so that the length from the bottom wall portion 16C is longer than that of the outer vertical wall portion 16A.

[0041] Further, the outer vertical wall portion 16A is disposed so as to protrude downward from the lower end portion 22B in order to attach the decorative girth 30. As shown in Fig. 3, an insertion hole 16D through which a tapping screw 19 described later is inserted is formed in the portion of the outer vertical wall portion 16A protruding downward from the lower end portion 22B.

[0042] Through holes (not shown) are formed in the floor girder 40B, which constitutes part of the upper floor unit 12B where the inner vertical wall portion 16B of the horizontal frame 16 and the inner vertical wall portion 16B abut, in the plate thickness direction, and the horizontal frame 16 and therefore the upper floor exterior wall frame 15 are fixed to the floor girder 40B by inserting bolts 18A from the horizontal frame 16 side into these through holes and fastening them with nuts 18B from the floor girder 40B side. In this embodiment, the fastener 18 is composed of the bolts 18A and the nuts 18B.

[0043] As shown in Fig. 3, a gap S is provided between the lower exterior wall panel 20A and the upper exterior wall panel 20B, and this gap S forms a horizontal joint. In other words, the horizontal joint is a joint between the lower exterior wall panel 20A and the upper exterior wall panel 20B. By disposing a decorative girth 30 in this joint, i.e., the gap S, the horizontal joint is concealed.

[0044] The decorative girth 30 includes a decorative water drainage member 30A that conceals more than half of the horizontal joint, and a waterproof water drainage member 30B that is located below the decorative water drainage member 30A and has a waterproof function against water spraying up on the decorative surface 24A of the exterior wall panel 20.

[0045] The decorative flashing member 30A is, for example, formed into a long shape from a plate material such as composite resin or ceramic material, and is configured in a color that matches the exterior appearance of the building 10. Various designs are incorporated to enhance the aesthetic look of the building 10. The decorative flashing member 30A has an upper wall portion 32A extending downward from an upper end disposed on the lower end portion 22B side of the exterior wall surface material 22 of the upper exterior wall panel 20B toward the lower side of the building, and an intermediate wall portion 32B extending obliquely downward from the upper wall portion 32A toward the outside of the building.

[0046] The decorative flashing member 30A also has a lower wall portion 32C that extends from the lower end of the middle wall portion 32B toward the lower side of the building. The lower wall portion 32C is formed with a folded portion 32D. This folded portion 32D is formed by bending a part of the lower wall portion 32C diagonally upward toward the inside of the building. The upper wall portion 32A also has a mounting hole 32E that is formed through the plate thickness direction. A plurality of mounting holes 32E are formed at intervals in the longitudinal direction of the decorative flashing member 30A.

[0047] The waterproof flashing member 30A includes a flashing body 34, a noncombustible portion 36, and a water-stopping portion 38 serving as a water-stopping material. The flashing body 34 includes an upper wall portion 34A extending downward from an upper end disposed on the lower end portion 22B side of the exterior wall facing material 22 of the upper exterior wall panel 20B, and an intermediate wall portion 34B extending obliquely downward from the upper wall portion 34A toward the outside of the building.

[0048] The main body 34 also has a lower wall 34C extending from the lower end of the middle wall 34B toward the lower side of the building. The lower wall 34C has a folded portion 34D. This folded portion 34D is formed by bending a part of the lower wall 34C diagonally upward toward the inside of the building, similar to the folded portion 32D of the lower design flashing member 30A. The upper wall 34A also has a mounting hole 34E formed through the plate thickness direction. The mounting hole 34E is formed at a position corresponding to the mounting hole 32E of the design flashing member 30A. That is, a plurality of mounting holes 34E are formed at intervals in the longitudinal direction of the main body 34.

[0049] The noncombustible section 36 is disposed on the building inner side of the upper wall section 34A of the drainage main body 34, on the building lower side excluding the vicinity of the mounting hole 34E, and is formed, for example, from an inorganic fiber material such as rock wool or glass wool. Note that the noncombustible section 36 may be a resin foam such as urethane foam or phenol foam, or may be a composite material combining a board material such as a gypsum board or a calcium silicate board with an inorganic fiber material or a resin foam.

[0050] The waterproof section 38 is formed of, for example, EPT SEALER, which is a semi-independent, semi-continuous type flexible foam made by mixing EPDM rubber (Ethylene Propylene Rubber) with a flame retardant and foaming the admixture. The waterproof section 38 is disposed on the lower side of the building of the intermediate wall section 34B and on the inner side of the building of the lower wall section 34C.

[0051] Also, a waterproof sheet 50, such as a stacking sheet made of a waterproof material such as a CR (chloroprene rubber) sheet, is attached to the decorative girth 30. As shown in Figures 2 and 3, one surface of the upper end 50A of the waterproof sheet 50 is attached to the back surface of the lower end 22B of the exterior wall facing material 22 of the upper exterior wall panel 20B, and the other surface of the upper end 50A is attached to the exterior side of the building of the outer vertical wall portion 16A of the horizontal frame 16, each surface being attached by a double-sided tape (not shown) having a waterproof function such as butyl tape.

[0052] Moreover, the waterproof sheet 50 has a lower end 50B extending between the decorative drainage member 30A and the waterproof drainage member 30B as shown in Fig. 2. As shown in Fig. 3, the waterproof sheet 50 has a double-sided tape 52 made of, for example, butyl tape or the like attached to the building interior side of the lower end 50B, and is attached to the building exterior side of the upper wall portion 34A of the waterproof drainage member 30B as shown in Fig. 2.

[0053] In addition, at positions on the lower end 50B of the waterproof sheet 50 corresponding to the mounting holes 32E, 34E of the decorative drainage member 30A and the waterproof drainage member 30B and the insertion hole 16D of the horizontal frame 16, through holes (not shown) are formed.

[0054] Next, a method of attaching the decorative girth 30 will be described. As shown in FIG. 3, the waterproof sheet 50 is attached to the back surface of the lower end 22B of the exterior wall surface material 22 of the upper exterior wall panel 20B and to the outer side surface of the building of the outer vertical wall portion 16A of the horizontal frame 16, with the lower end 50B positioned on the upper side of the building. In this state, the waterproof water-repelling member 30B is placed in the gap S. As shown in FIG. 2, the waterproof water-repelling member 30B has the water-stopping portion 38 pressed against the small end surface 21 of the lower exterior wall panel 20A, and as shown in FIG. 3, the mounting hole 34E formed in the upper wall portion 34A is aligned with the insertion hole 16D of the horizontal frame 16 to abut the upper wall portion 34A against the horizontal frame 16. The water-stopping portion 38 is elastically deformed when pressed.

[0055] Next, the lower end 50B of the waterproof sheet 50 is attached to the outer side of the building of the upper wall 34A of the waterproof flashing member 30B with double-sided tape 52. Then, the mounting hole 32E formed in the upper wall 32A of the decorative flashing member 30A is aligned with the through hole of the waterproof sheet 50, the mounting hole 34E formed in the upper wall 34A, and the insertion hole 16D of the horizontal frame 16, and the tapping screw 19 is inserted from the outer side of the building of the decorative flashing member 30A through the mounting hole 32E of the decorative flashing member 30A, the mounting hole 34E of the waterproof flashing member 30B, the through hole of the waterproof sheet 50, and the insertion hole 16D of the horizontal frame 16 in this order to fasten them. As a result, the decorative flashing member 30A, the waterproof flashing member 30B, and the waterproof sheet 50 are fixed to the horizontal frame 16.

[0056] As shown in Figure 2, when the waterproof sheet 50 is fixed to the horizontal frame 16, the upper end 50A is attached between the back surface (the building interior side) of the lower end 22B of the exterior wall facing material 22 of the upper exterior wall panel 20B and the building exterior side of the outer vertical wall portion 16A of the horizontal frame 16, and the lower end 50B is attached to the building exterior side of the upper wall portion 34A of the waterproof water drainage member 30B, so that the cross-sectional shape perpendicular to the longitudinal direction is approximately crank-shaped.

[0057] 2, the decorative girth 30 is formed so that the building exterior faces of the lower wall portion 32C of the decorative flashing member 30A and the lower wall portion 34C of the waterproof flashing member 30B are positioned on approximately the same plane when the decorative girth 30 is attached to the horizontal frame 16. The decorative girth 30 is also formed so that there is a gap D1 between the lower end of the lower wall portion 32C of the decorative flashing member 30A and the upper end of the lower wall portion 34C of the waterproof flashing member 30B. In this embodiment, the gap D1 is, for example, 4 mm or more.

[0058] As shown in FIG. 2, in the decorative girth 30, when fixed to the horizontal frame 16, water seeping in between the upper exterior wall panel 20B and the waterproof sheet 50 is drained along the surface of the decorative flashing member 30A facing the outside of the building. The path along which the water flows in this way is the first drainage channel W1 (arrow W1 in FIG. 2). Water seeping in from the waterproof sheet 50 between the decorative flashing member 30A and the waterproof flashing member 30B is drained along the surface of the waterproof sheet 50 facing the outside of the building, as well as the surfaces of the middle wall portion 34B and the lower wall portion 34C of the waterproof flashing member 30B facing the outside of the building. The path along which the water flows in this way is the second drainage channel W2 (arrow W2 in FIG. 2). The second drainage channel W2 corresponds to the drainage channel of the present invention.

[0059] Next, the operation and effects of the first embodiment will be described.

[0060] FIG. 6 shows a vertical cross-sectional view of the vicinity of an exterior wall including a conventional decorative girth 130. As shown in FIG. 6, conventionally, the upper end 150A of the waterproof sheet 150 is fixed between the upper exterior wall panel 120B and the horizontal frame 116, and the lower end 150B of the waterproof sheet 150 extending downward from between the upper exterior wall panel 120B and the horizontal frame 116 is attached to the outer surface of the building of the lower exterior wall panel 120A. In general, the surface to which the waterproof sheet 150 is attached needs to be flat, and in order to attach the lower end 150B to the outer surface of the building of the lower exterior wall panel 120A, the decorative surface material 124 must be scraped off to form a flat surface. Therefore, the shape of the decorative surface 124A of the upper exterior wall panel 120B and the lower exterior wall panel 120A is different.

[0061] Furthermore, the waterproof sheet 150 attached to the flat surface formed on the outer side of the building of the lower exterior wall panel 120A must have a certain amount of width in the vertical direction of the building in preparation for water splashing up, and in order to hold down and hide the waterproof sheet 150, the width H of the decorative girth 130 in the vertical direction of the building becomes large, for example, about 125 mm, and the visible portion of the decorative girth 130 becomes large. Furthermore, the decorative girth 130 needs to have a noncombustible material on its inner surface for fire prevention, and the legs 200 and the like used for reinforcing the decorative girth 130 when it is attached need to be hidden, so the width T in the internal and external directions of the building becomes large, for example, about 20 mm.

[0062] Moreover, in the waterproof sheet 150, a middle portion 150C located between the upper end portion 150A and the lower end portion 150B is not fixed and is in an unstable state.

[0063] In contrast, the decorative girth 30 of the first embodiment includes a decorative water-repellent member 30A having a design function and a waterproof water-repellent member 30B that is a separate part from the decorative water-repellent member 30A and has a waterproof function against water blowing up. The decorative girth 30 can hide more than half of the horizontal joint between the lower exterior wall panel 20A and the upper exterior wall panel 20B with the decorative water-repellent member 30A. In addition, even if water blows up on the design surface 24A of the lower exterior wall panel 20A due to wind or the like, the decorative girth 30 can prevent water from entering the upper side of the building with the waterproof water-repellent member 30B. In this way, by making the decorative girth 30 into a separate part for each function, each part can be made smaller while fulfilling its respective role.

[0064] Specifically, in the decorative girth 30 of the first embodiment, the waterproof sheet 50 is fixed to the horizontal frame 16 as the building body together with the decorative flashing member 30A, and the lower end 50B is located in the gap S formed between the lower exterior wall panel 20A and the upper exterior wall panel 20B. That is, the lower end 50B of the waterproof sheet 50 is not exposed to the outside of the building of the lower exterior wall panel 20A. Therefore, the width of the waterproof sheet 50 in the vertical direction of the building, which needs to be hidden, can be reduced by about 1 / 3, for example. As a result, as shown in FIG. 2, the width H1 from the upper end of the lower wall portion 32C of the decorative flashing member 30A to the lower end of the lower wall portion 34C of the waterproof flashing member 30B can be made smaller than the width H of the conventional decorative girth 130 (see FIG. 6), so that it is possible to realize a reduction in the size of the visible part while having both a design function and a waterproof function.

[0065] In the decorative girth 30 of the first embodiment, as shown in Fig. 2, the noncombustible portion 36 is provided on the building interior side of the upper wall portion 34A of the waterproof flashing member 30B, so that the noncombustible portion 36 can be positioned inward of the building interior side of the exterior wall panel 20 in the gap S. This allows the width of the decorative girth 30 in the building interior / exterior direction to be smaller than the conventional width T (see Fig. 6).

[0066] In addition, in the decorative girth 30 of the first embodiment, the lower end 50B of the waterproof sheet 50 is not attached to the surface of the lower exterior wall panel 20A facing the outside of the building, so there is no need to form a flat surface by scraping off the decorative surface material 24. Therefore, a common exterior wall panel 20 can be used for the upper exterior wall panel 20B and the lower exterior wall panel 20A.

[0067] In addition, in the decorative girth 30 of the first embodiment, the waterproof sheet 50 is fixed to the horizontal frame 16 by tapping screws 19 together with the decorative drainage member 30A, thereby improving the adhesion of the waterproof sheet 50 to the waterproof drainage member 30B, which is the attachment surface of the waterproof sheet 50.

[0068] In addition, the decorative girth 30 of the first embodiment has a second drainage channel W2 as a drainage channel for draining water that seeps in from the waterproof sheet 50 between the decorative drainage member 30A and the waterproof drainage member 30B on the design surface 24A side of the exterior wall panel 20. Therefore, for example, even if the amount of water seeps in from a portion of the waterproof sheet 50 fixed by the tapping screw 19, the seeped water can be drained from the second drainage channel W2.

[0069] Furthermore, in the decorative girth 30 of the first embodiment, a water-stopping portion 38 serving as a water-stopping material is integrally provided in the waterproof drainage member 30B, so that the water-stopping tape 138 that was conventionally attached to the edge surface of the lower exterior wall panel 120A can be eliminated.

[0070] In addition, the lower wall portion 32C of the decorative drainage member 30A and the lower wall portion 34C of the waterproof drainage member 30B are provided with the folded portions 32D and 34D, respectively, which improves the rigidity of the decorative drainage member 30A and the waterproof drainage member 30B. Therefore, deformation of the decorative drainage member 30A and the waterproof drainage member 30B can be suppressed.

[0071] Furthermore, the bottom wall portion 32C of the decorative flashing member 30A and the bottom wall portion 34C of the waterproof flashing member 30B are provided with the folded portions 32D and 34D, respectively, so that the gap S is less visible when looking up at the decorative flashing member 30A and the waterproof flashing member 30B from the outside of the building. In other words, the appearance quality can be improved.

[0072] Furthermore, the decorative girth 30 has a folded portion 34D on the lower wall portion 34C of the waterproof water-repellent member 30B, so that even if the water flows upward along the design surface 24A of the design panel 24 due to the wind, that is, even if the water is blown up, the folded portion 34D prevents the water from flowing further upward. Even if water does seep in, the waterproof water-repellent member 30B has a water-stopping portion 38 integrally provided as a water-stopping material, so the water does not immediately seep into the building. Therefore, it is possible to prevent the water flowing upward from seeping into the building.

[0073] In addition, the decorative girder 30 is formed so that the exterior building surfaces of the lower wall portion 32C of the decorative drainage member 30A and the lower wall portion 34C of the waterproof drainage member 30B are positioned on approximately the same plane, thereby creating a neat and tidy exterior to the building.

[0074] Furthermore, since the building 10 of the first embodiment is provided with the decorative girth 30, the effects of the decorative girth 30 can be enjoyed.

[0075] In the first embodiment, the exterior side of the building of the lower wall portion 32C of the decorative flashing member 30A and the lower wall portion 34C of the waterproof flashing member 30B are arranged to be located on approximately the same plane, but the present invention is not limited to this. For example, the exterior side of the building of the lower wall portion 34C of the waterproof flashing member 30B may protrude or be recessed slightly from the exterior side of the building of the lower wall portion 32C of the decorative flashing member 30A.

[0076] <Second embodiment> The decorative girth 60 according to the second embodiment will be described below with reference to Figures 4 and 5. Figure 4 is a vertical cross-sectional view of the exterior wall panel 20 including the decorative girth 60 according to the second embodiment, and Figure 5 is an exploded enlarged cross-sectional view of the decorative girth 60 in Figure 4. In each figure, the same components as those in the first embodiment are indicated by the same reference numerals and detailed description will be omitted. Also, in Figure 5, the decorative panel 24 and horizontal frame 16 shown in Figure 4 are omitted. The decorative girth 60 of the second embodiment is applied to a building 10A having a similar configuration to the building 10 of the first embodiment.

[0077] As shown in Figures 4 and 5, the decorative girth 60 comprises a decorative drainage member 60A that conceals more than half of the horizontal joint, and a waterproof drainage member 60B that is located below the decorative drainage member 60A and has a waterproof function against water spraying up on the decorative surface 24A of the exterior wall panel 20.

[0078] The decorative flashing member 60A is formed in an elongated shape from a plate material such as a composite resin or a ceramic material, and is configured in a color that matches the exterior of the building 10A. Various designs are used to enhance the beauty of the building 10A. The decorative flashing member 60A includes a flashing body 62 and a non-combustible part 64. The flashing body 62 has an upper wall part 62A that is disposed on the lower end 22B side of the exterior wall surface material 22 of the upper exterior wall panel 20B and extends downward from the upper end of the upper wall part 62A toward the outside of the building. The upper wall part 62A has a mounting hole 62D that is formed through the plate thickness direction. A plurality of mounting holes 62D are formed at intervals in the longitudinal direction of the decorative flashing member 60A.

[0079] The drain body 62 also has a lower wall 62C extending from the building outer end of the horizontal wall 62B toward the building lower side. The lower wall 62C has a horizontal part 62E extending substantially horizontally toward the building inner side below the building vertical center, and a vertical part 62F extending substantially vertically from the building inner end of the horizontal part 62E toward the building upper side. In this embodiment, the horizontal part 62E and the vertical part 62F form an engaged part 80A with which an engaging part 80B described later engages.

[0080] The noncombustible portion 64 is disposed on the building lower side of the horizontal wall portion 62B of the drain body 62, and on the building upper side of the engaged portion 80A on the building inner side of the lower wall portion 62C, and is formed of an inorganic fiber material such as rock wool or glass wool, for example. The noncombustible portion 36 may be a resin foam such as urethane foam or phenol foam, or may be a composite material combining a board material such as a gypsum board or a calcium silicate board with an inorganic fiber material or a resin foam.

[0081] The waterproof drainage member 60B is made of sheet metal and has an upper wall portion 66A extending downward from the upper end of the exterior wall facing material 22 of the lower exterior wall panel 20A, and an intermediate wall portion 66B extending obliquely downward from the lower end of the upper wall portion 66A toward the outside of the building. The waterproof drainage member 60B also has a lower wall portion 66C extending downward from the lower end of the intermediate wall portion 66B toward the lower side of the building.

[0082] The waterproof drainage member 60B has a horizontal section 66D extending substantially horizontally from the top end of the upper wall section 66A toward the outside of the building, and a vertical section 66E extending substantially vertically from the end of the horizontal section 66D on the outside of the building toward the lower side of the building. The vertical section 62F of the decorative drainage member 60A is longer than the vertical section 66E of the waterproof drainage member 60B. In this embodiment, the horizontal section 66D and the vertical section 66E form an engagement section 80B that engages with the engaged section 80A. The engaged section 80A and the engagement section B form the engagement means 80.

[0083] A waterproof sheet 70 made of the same material as the waterproof sheet 50 of the first embodiment is attached to the decorative girth 60. As shown in Figs. 4 and 5, one side of the upper end 70A of the waterproof sheet 70 is attached to the back side of the lower end 22B of the exterior wall surface material 22 of the upper exterior wall panel 20B, and the other side of the upper end 70A is attached to the building exterior side of the outer vertical wall portion 16A of the horizontal frame 16 by a double-sided tape 72 having a waterproof function, such as a butyl tape. As shown in Fig. 4, the lower end 70B of the waterproof sheet 70 extends between the back side (building interior side) of the upper wall portion 66A of the waterproof water drainage member 60B and the surface (building exterior side) of the exterior wall surface material 22 of the lower exterior wall panel 20A. As shown in Fig. 5, the double-sided tape 72 is attached to the building interior side of the lower end 70B of the waterproof sheet 70, and as shown in Fig. 4, the waterproof sheet 70 is attached to the surface (building exterior side) of the exterior wall surface material 22.

[0084] Furthermore, at positions in the upper end portion 70A of the waterproof sheet 70 corresponding to the mounting hole 62D of the decorative drip-water member 60A and the insertion hole 16D of the horizontal frame 16, through holes (not shown) are formed.

[0085] Next, a method of attaching the decorative girth 60 will be described. As shown in Fig. 5, the upper end 70A of the waterproof sheet 70 is attached to the back surface (the building interior side) of the lower end 22B of the exterior wall facing material 22 of the upper exterior wall panel 20B, and the lower end 70B is attached to the surface (the building exterior side) of the exterior wall facing material 22 of the lower exterior wall panel 20A. Then, the engaging portion 80B of the waterproof flashing member 60B is engaged with the engaged portion 80A of the decorative flashing member 60A.

[0086] With the mounting holes 62D formed in the upper wall portion 62A of the decorative flashing member 60A aligned with the through holes of the waterproof sheet 50 and the insertion holes 16D of the horizontal frame 16, tapping screws 19 are inserted from the outside of the building of the decorative flashing member 70A through the mounting holes 62D of the decorative flashing member 60A, the through holes of the waterproof sheet 50, and the insertion holes 16D of the horizontal frame 16, in that order, to fasten them together. This fixes the decorative flashing member 60A and the waterproof sheet 70 to the horizontal frame 16.

[0087] As shown in Figure 4, when the waterproof sheet 70 is fixed to the horizontal frame 16, the upper end 70A is fixed between the back surface (the building interior side) of the lower end 22B of the exterior wall surface material 22 of the upper exterior wall panel 20B and the building exterior side of the outer vertical wall portion 16A of the horizontal frame 16, and the lower end 70B is fixed between the building interior side of the upper wall portion 66A of the waterproof water drainage member 60B and the surface (the building exterior side) of the exterior wall surface material 22 of the lower exterior wall panel 20A.

[0088] 4, the decorative girth 60 is formed so that the building exterior faces of the lower wall portion 62C of the decorative flashing member 60A and the lower wall portion 66C of the waterproof flashing member 60B are positioned on approximately the same plane when the decorative girth 60 is attached to the horizontal frame 16. The decorative girth 60 is also formed so that there is a gap D2 between the lower end of the lower wall portion 62C of the decorative flashing member 60A and the upper end of the lower wall portion 66C of the waterproof flashing member 60B. In this embodiment, the gap D2 is, for example, 4 mm or more.

[0089] Next, the operation and effects of the second embodiment will be described.

[0090] The decorative girth 60 of the second embodiment includes a decorative water-repellent member 60A having a design function and a waterproof water-repellent member 60B that is a separate part from the decorative water-repellent member 60A and has a waterproof function against water blowing up. The decorative girth 60 can hide more than half of the horizontal joint between the lower exterior wall panel 20A and the upper exterior wall panel 20B with the decorative water-repellent member 60A. In addition, even if water blows up on the design surface 24A of the lower exterior wall panel 20A due to wind or the like, the decorative girth 60 can prevent water from entering the upper side of the building with the waterproof water-repellent member 60B. In this way, by making the decorative girth 60 into a separate part for each function, each part can be made smaller while fulfilling its respective role.

[0091] Specifically, in the decorative girth 60 of the second embodiment, the lower end 70B of the waterproof sheet 70 is held down by the waterproof water drainage member 60B. That is, the lower end 50B of the waterproof sheet 70 is not exposed to the building exterior side of the lower exterior wall panel 20A. Therefore, the width of the waterproof sheet 70 in the vertical direction of the building, which needs to be hidden, can be made smaller than in the past. As a result, as shown in FIG. 4, the width H2 from the upper end to the lower end of the lower wall portion 62C of the decorative water drainage member 60A can be made smaller than the width H of the conventional decorative girth 130 (see FIG. 6), so that it is possible to realize a reduction in the size of the visible part while maintaining both the decorative function and the waterproof function.

[0092] Also, as shown in Figure 4, according to the second embodiment of the decorative girth 60, when fixed to the horizontal frame 16, water that seeps in between the upper exterior wall panel 20B and the waterproof sheet 70 is drained along the surface of the decorative water flashing member 60A facing outside the building.

[0093] In addition, according to the decorative girth 60 of the second embodiment, the lower end 70B of the waterproof sheet 70 extends between the design surface 24A of the lower exterior wall panel 20B and the waterproof drainage member 60B, so that the waterproof drainage member 60B can press the lower end 70B of the waterproof sheet 70 against the design surface 24A of the lower exterior wall panel 20B. This can improve the adhesion of the waterproof sheet 70 to the design surface 24A of the lower exterior wall panel 20B.

[0094] In addition, in the decorative girth 60 of the second embodiment, the decorative drainage member 60A and the waterproof drainage member 60B are provided with engagement means 80 for engaging with each other, so that the decorative drainage member 60A and the waterproof drainage member 60B can be integrated by engaging them with each other using the engagement means 80.

[0095] Moreover, the waterproof drainage member 60B of the decorative girth 60 in the second embodiment is made of a sheet metal member.

[0096] As shown in FIG. 6, the conventional decorative girth 130 has a surface material having a design surface and a fireproof non-combustible material arranged to press the waterproof sheet 150 to the lower exterior wall panel 120A side, so that the thickness in the direction inside and outside the building is thick. The waterproof drainage member 60B of the decorative girth 60 of the second embodiment is made of a sheet metal member, so that the thickness can be reduced. Since the waterproof sheet 70 is pressed to the lower exterior wall panel 20A side by the waterproof drainage member 60B, the design drainage member 60A does not need to press the waterproof sheet 70 to the lower exterior wall panel 20A side. For this reason, the design drainage member 60A only needs to arrange a non-combustible material in the horizontal joints of the exterior wall panels 20 adjacent to each other above and below, so that the thickness from the reference line of the exterior wall panel 20 (for example, the center of the decorative surface material in the direction inside and outside the building) to the design surface 24A can be made thinner than in the conventional case. In this way, the thickness of both the waterproof drainage member 60A and the design drainage member 60B can be made thinner.

[0097] In addition, the waterproof sheet 70 can be held down by the entire building interior side surface of the upper wall portion 66A of the waterproof dripping member 60B, thereby improving adhesion.

[0098] Furthermore, since the building 10A of the second embodiment is provided with the decorative girth 60, the effects of the decorative girth 60 can be enjoyed.

[0099] In the second embodiment, the engaging means 80 is formed of the engaged portion 80A and the engaging portion 80B having a U-shaped cross section as shown in Fig. 5, but the present invention is not limited to this. As long as the engaged portion 80A and the engaging portion 80B can be engaged with each other, they may have a concave-convex shape, for example, and the shape can be changed as appropriate.

[0100] Although an embodiment of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement the present invention in various other modified forms without departing from the spirit and scope of the present invention.
