Description

[Technical Field]

[0001] The present invention relates to a fitting, and more particularly to a fitting provided with a dry sealing member surrounding the periphery of a frame. [Background technology]

[0002] In fixtures such as curtain walls, dry sealing members are provided around the periphery of the frame, ensuring a tight seal. The sealing members extend along the length of each of the upper and lower horizontal frames and the left and right vertical frames, and are endless by connecting their ends (see, for example, Patent Document 1). In this type of fixture, for example, when curtain walls are adjacent, the sealing members can be abutted against each other to prevent outside water, such as rainwater, from entering the room. Furthermore, when a fixture is installed in an opening in the exterior wall of a building, the sealing member can be abutted against the inner wall surface of the opening to ensure a tight seal.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-184816 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when using this type of fixture to construct a bay window, that is, when constructing a bay window by installing the vertical frame so that it protrudes from the exterior wall surface to the outside, it is necessary to protrude the vertical frame to the outside while ensuring that the above-mentioned sealing member is in contact with the interior wall surface of the opening. This means that the dimension of the vertical frame along the projected direction becomes long, which is not necessarily desirable when considering manufacturing costs.

[0005] In view of the above circumstances, the present invention aims to provide a fitting that can reduce manufacturing costs and ensure sealing performance even when forming a bay window. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objectives, the building fixture of the present invention is a building fixture comprising a frame body having upper and lower horizontal frames and left and right vertical frames, and a dry sealing member arranged to surround the periphery of the frame body, wherein the sealing member is arranged on the visible surface facing the room on at least one of the left and right vertical frames, and is characterized by comprising a vertical sealing portion extending along the length of the vertical frame. [Effects of the Invention]

[0007] According to the present invention, a bay window can be constructed with the vertical seal portion provided on the visible surface of the vertical frame on the indoor side abutting the exterior wall surface of the building, thereby ensuring sealing without increasing the dimension along the visible direction of the vertical frame, which is advantageous in terms of manufacturing costs.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Preferred embodiments of the fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" will be used below. The "invisible direction" is the direction along the depth of the fittings, as indicated by arrow A in the drawings. A surface along the invisible direction will be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction in the case of an object that extends horizontally, such as a sill. In the case of an object that extends vertically, such as a vertical frame, the "visible direction" is the horizontal direction perpendicular to the invisible direction. A surface along the invisible direction will be referred to as a "visible face."

[0010] 1 to 7 show fittings according to an embodiment of the present invention, illustrating a curtain wall 2 that is placed between exterior wall panels 1 to form the exterior wall of a building together with the exterior wall panels 1. The building has a ceiling panel C provided between an upper floor slab S1 and a lower floor slab S2, thereby forming an interior space below the ceiling panel C and an attic space above the ceiling panel C. The exterior wall panel 1 and curtain wall 2 are disposed on the outdoor side of the upper and lower floor slabs S1, S2.

[0011] The exterior wall panel 1 has an outer shape that is vertically long and rectangular, with the vertically long sides extending vertically. The exterior wall panels 1 are arranged side by side, one above the other, with their end faces close together, and are also arranged side by side, with a gap between their side faces. In the example shown, the exterior wall panel 1 has a length equivalent to the distance between the upper and lower floor slabs S1, S2. A panel seal member 1e (see Figure 15) is provided between the upper and lower exterior wall panels 1.

[0012] The curtain wall 2 is made up of a frame 10 formed by assembling an upper frame (horizontal frame) 11, a lower frame (horizontal frame) 12, and left and right vertical frames 13, 14 all around, with transoms 15 arranged horizontally between the left and right vertical frames 13, 14. An upper panel 16 made of single-pane glass or the like is attached to the area surrounded by the upper frame 11, transom 15, and left and right vertical frames 13, 14, and a lower panel 17 made of double-pane glass or the like is attached to the area surrounded by the transom 15, lower frame 12, and left and right vertical frames 13, 14. The upper frame 11, lower frame 12, left and right vertical frames 13, 14, and transom 15 are all extruded shapes formed from metal such as aluminum alloy, and each is configured to have a cross-sectional shape that is approximately uniform along its length.

[0013] As shown in Figure 8, the upper frame 11 has an upper inner peripheral wall 11a, an upper inner wall 11b, an upper outer wall 11c, an upper groove-forming wall 11d, and an upper outer peripheral wall 11e. The upper inner peripheral wall 11a is a flat plate extending approximately horizontally along the projection direction. The upper inner wall 11b is a flat plate extending upward from the edge of the upper inner peripheral wall 11a located on the indoor side. A panel bracket 11f is attached to the indoor side surface of the upper inner wall 11b, and an upper fire-resistant panel receiving groove 11g opening downward is formed between the panel bracket 11f and the upper outer wall 11c. The upper outer wall 11c is a flat plate extending upward from the edge of the upper inner peripheral wall 11a located on the outdoor side. The upper groove-forming wall 11d is a flat plate extending approximately horizontally from the upper edge of the upper outer wall 11c toward the exterior. An upper ledge 11h is attached to the upper groove-forming wall 11d, and an upper panel accommodating groove 11i is formed between the upper ledge 11h and the upper outer wall 11c. The upper outer peripheral wall 11e extends from the upper edge of the upper inner wall 11b toward the exterior. The upper outer peripheral wall 11e is provided with an inner sealant mounting portion 20a and an outer sealant mounting portion 20b from the interior side. The inner sealant mounting portion 20a and the outer sealant mounting portion 20b are groove-like spaces that open upward and extend the entire length of the upper frame 11 with a gap between them. The longitudinal dimension of the upper frame 11 is set to the length spanning the outer wall surfaces 1a of the side-by-side exterior wall panels 1.

[0014] As shown in Figure 9, the lower frame 12 has a lower inner peripheral wall portion 12a, a lower inner wall portion 12b, a lower outer wall portion 12c, a lower groove-forming wall portion 12d, and a lower outer peripheral wall portion 12e. The lower inner peripheral wall portion 12a is a flat plate extending approximately horizontally along the projection direction. The lower inner wall portion 12b is a flat plate extending downward from the edge of the lower inner peripheral wall portion 12a located on the indoor side. The lower outer wall portion 12c is a flat plate extending downward from the edge of the lower inner peripheral wall portion 12a located on the outdoor side. The lower groove-forming wall portion 12d extends approximately horizontally from the lower edge of the lower outer wall portion 12c toward the outdoor side. A lower ledge 12f is attached to the lower groove-forming wall 12d, and a lower panel accommodating groove 12g is formed between the lower ledge 12f and the lower outer wall 12c. The lower outer peripheral wall 12e extends between the lower edge of the lower inner wall 12b and the lower edge of the lower outer wall 12c. An inner sealant mounting portion 20a and an outer sealant mounting portion 20b are provided on this lower outer peripheral wall 12e from the interior side. The inner sealant mounting portion 20a and the outer sealant mounting portion 20b are groove-shaped cavities that open downward and extend the entire length of the lower frame 12 with a gap between them. The distance between the inner sealant mounting portion 20a and the outer sealant mounting portion 20b is the same as the distance between the inner sealant mounting portion 20a and the outer sealant mounting portion 20b provided on the upper frame 11. The distance from the visible surface of the lower inner wall portion 12b facing the room to the inner seal material mounting portion 20a and the distance from the visible surface of the upper inner wall portion 11b facing the room to the inner seal material mounting portion 20a and the distance from the visible surface of the upper inner wall portion 11b provided on the upper frame 11 to the inner seal material mounting portion 20a and the outer seal material mounting portion 20b. The dimension of this lower frame 12 along the projection direction is the same as the dimension of the upper frame 11 along the projection direction, and the dimension along the longitudinal direction is also the same as that of the upper frame 11.

[0015] As shown in Figures 10 and 11, the left and right vertical frames 13, 14 are configured with cross-sectional shapes that are approximately symmetrical to each other, and include a vertical main body portion 13a, a vertical outer peripheral sight wall portion 13b, a vertical groove-forming wall portion 13c, a vertical room-forming wall portion 13d, a vertical inner peripheral sight wall portion 13e, a vertical inner peripheral sight wall portion 13f, a vertical inner sight wall portion 13g, and a vertical outer peripheral sight wall portion 13h. The vertical main body portion 13a is flat and extends at an angle gradually inward toward the interior. In the illustrated example, the outer peripheral portion of the vertical main body portion 13a is inclined at an angle of approximately 45° from the exterior wall surface of the building, with the inner peripheral side of the vertical main body portion 13a as the center. The vertical outer peripheral sight wall 13b extends inward from the outer peripheral edge of the vertical main body 13a in the sight direction, while the vertical groove-forming wall 13c extends from the outer peripheral edge of the vertical main body 13a in the sight direction toward the exterior. A vertical ledge 13i is attached to the vertical groove-forming wall 13c, and a vertical panel storage groove 13j is formed between the vertical ledge 13i and the vertical outer peripheral sight wall 13b. As is clear from the figure, a cover 13k is integrally formed with the vertical ledge 13i. The cover 13k extends from the outer peripheral edge of the vertical main body 13a toward the interior of the room in the sight direction. The extending edge of the cover 13k is located on the same plane as the sight surface facing the interior of the vertical inner sight wall 13g, described below. An engaging claw 13m is provided on the inner peripheral portion of the cover portion 13k so as to protrude toward the inner peripheral side. The vertical chamber-forming wall portion 13d extends from the inner peripheral edge of the vertical main body portion 13a along the projection direction toward the exterior of the room, then gradually slopes toward the exterior toward the outer peripheral side, extending toward the extending edge of the vertical outer peripheral sight wall portion 13b. As shown in FIG. 11, the vertical frame located on the right side as viewed from the exterior (hereinafter referred to as the right vertical frame 14 for distinction) has a chamber cover 14a attached to close the gap between the vertical chamber-forming wall portion 13d and the vertical outer peripheral sight wall portion 13b. As shown in FIG. 10, the vertical frame located on the left side as viewed from the exterior (hereinafter referred to as the left vertical frame 13 for distinction) has a ventilation cover 18 attached between the vertical chamber-forming wall portion 13d and the vertical outer peripheral sight wall portion 13b.The ventilation cover 18 has multiple horizontal slits 18a arranged vertically and horizontally, and is arranged to close the gap between the vertical chamber-forming wall 13d and the vertical outer peripheral sight wall 13b via the cover holder 19. As shown in Figures 10 and 11, the vertical inner peripheral sight wall 13e extends inward from the inner peripheral edge of the vertical main body 13a in the sight direction. The vertical inner peripheral sight wall 13f extends in the sight direction from the inner peripheral edge of the vertical inner peripheral sight wall 13e toward the room. As shown in Figure 6, inner panel brackets 13n and outer panel brackets 13p are attached to the inner peripheral sight surface of the vertical inner peripheral sight wall 13f above the ceiling panel material C, forming a vertical fire-resistant panel storage groove 13q between them. As shown in Figures 10 and 11, the vertical inner sight wall 13g extends from the interior edge of the vertical inner peripheral sight wall 13f toward the exterior. The vertical inner sight wall 13g is provided with an inner sealant mounting portion 20a and an outer sealant mounting portion 20b from the inner periphery. The inner sealant mounting portion 20a and the outer sealant mounting portion 20b are groove-shaped cavities that open toward the interior and extend along the entire length of the vertical frames 13 and 14, with a gap between them. The spacing between the inner sealant mounting portion 20a and the outer sealant mounting portion 20b is the same as the spacing between the inner sealant mounting portion 20a and the outer sealant mounting portion 20b on the upper frame 11. The vertical outer peripheral sight wall 13h extends from the portion of the vertical inner sight wall 13g that corresponds to the inner wall of the outer sealant mounting portion 20b toward the exterior. The edge of this vertical outer peripheral projection wall 13h located on the exterior side of the room is connected to a portion of the vertical main body 13a located near the exterior periphery, and a vertical frame hollow portion 21 is formed between the vertical main body 13a, the vertical inner peripheral projection wall 13e, the vertical inner peripheral projection wall 13f, and the vertical inner peripheral projection wall 13g. A cover engagement piece 13r is provided on the exterior peripheral surface of the vertical outer peripheral projection wall 13h, closer to the interior side and spaced apart from the bottom wall of the external seal material mounting portion 20b. The cover engagement piece 13r extends from the projection surface of the vertical outer peripheral projection wall 13h toward the exterior periphery and then bends toward the interior side of the room, and engages with the engagement claw 13m of the cover portion 13k described above.

[0016] Each of the left and right vertical frames 13, 14 has two support walls 13s, and as shown in Figure 12, sealant holders 22, 23 are attached to the upper and lower ends of the vertical outer peripheral projection wall 13h. The support walls 13s are flat plates extending approximately parallel to each other along the projection direction and are formed in the vertical frame hollow 21 at the portions corresponding to the inner sealant mounting portions 20a. That is, the support walls 13s extend from the portions of the vertical inner projection wall 13g corresponding to the inner and outer peripheral side walls of the inner sealant mounting portions 20a toward the exterior in the projection direction, and each extending edge is connected to the vertical main body 13a, dividing the vertical frame hollow 21. Between the support walls 13s, end inner sealant mounting portions 20c are formed, each having a width approximately equal to the groove width of the inner sealant mounting portion 20a formed in the upper frame 11. The sealing material holders 22, 23 have mounting portions 22a, 23a extending along the vertical outer peripheral projected wall portion 13h, bottom wall portions 22b, 23b extending perpendicularly from the end side edges of the mounting portions 22a, 23a, and side wall portions 22c, 23c extending perpendicularly from the edges of the bottom wall portions 22b, 23b toward the edge of the vertical outer peripheral projected wall portion 13h, and form an end outer sealing material mounting portion 20d between the vertical outer peripheral projected wall portion 13h. As is clear from the figure, the sealing material holder 23 attached to the upper end of the vertical outer peripheral projected wall portion 13h has a canopy portion 23d extending perpendicularly outward from the base side edge of the mounting portion 23a and then extending toward the base end side, and a drainage space 23e is secured between the vertical outer peripheral projected wall portion 13h.

[0017] Furthermore, two baffle plates 13t are provided in the drainage hollow portion 21a, which is composed of the vertical main body portion 13a, the support wall portion 13s, the vertical inner sight wall portion 13g, and the vertical outer peripheral sight wall portion 13h. One baffle plate 13t extends inward along the sight direction from a portion of the vertical outer peripheral sight wall portion 13h corresponding to the cover engagement piece 13r, then bends toward the interior of the room. The other baffle plate 13t protrudes in a direction perpendicular to the vertical main body portion 13a from a portion approximately midway between the support wall portion 13s and the vertical outer peripheral sight wall portion 13h, then bends toward the support wall portion 13s. The longitudinal dimension of these vertical frames 13, 14 is approximately the same as the height dimension of the exterior wall panel 1, and the sight dimension is larger than the sight dimension of the upper frame 11.

[0018] As shown in FIG. 13( a), the upper frame 11 and the lower frame 12 are connected to the left and right vertical frames 13, 14 configured as described above, with joint end surfaces 24 at both ends. That is, the upper frame 11 and the lower frame 12 have joint end surfaces 24 that are inclined so that the longitudinal dimensions gradually decrease toward the interior of the room, and are connected to the ends of the vertical frames 13, 14 via the joint end surfaces 24. In the illustrated example, the joint end surfaces 24 are formed so that the inclination angle is approximately 45°. In the upper frame 11 and the vertical frames 13, 14 connected to each other via the joint end surfaces 24, as shown in FIG. 13( b), the inner sealant mounting portion 20a formed on the upper frame 11 is positioned corresponding to the end inner sealant mounting portion 20c provided on the vertical frames 13, 14, and the inner sealant mounting portion 20a and the end inner sealant mounting portion 20c are bent 90° and connected to each other. The outer seal material mounting portion 20b of the upper frame 11 corresponds to the outer seal material mounting portion 20d, and the outer seal material mounting portion 20b and the outer seal material mounting portion 20d are bent 90° and connected to each other. Although not shown in the figure, the inner seal material mounting portion 20a of the lower frame 12 corresponds to the inner seal material mounting portion 20c of the vertical frames 13 and 14, and the inner seal material mounting portion 20a and the inner seal material mounting portion 20c are bent 90° and connected to each other. The outer seal material mounting portion 20b of the lower frame 12 corresponds to the outer seal material mounting portion 20d, and the outer seal material mounting portion 20b and the outer seal material mounting portion 20d are bent 90° and connected to each other.

[0019] That is, an endless outer peripheral seal member 25 can be attached to the series of outer seal material attachment portions 20b and end outer seal material attachment portions 20d of the four-way assembled upper frame 11, lower frame 12, and left and right vertical frames 13, 14, and an endless inner peripheral seal member 26 can be attached to the series of inner seal material attachment portions 20a and end inner seal material attachment portions 20c. More specifically, as shown in Figures 6 and 7, the outer peripheral seal member 25 is endless and has horizontal seal portions 25a along the length of the upper frame 11 and lower frame 12, vertical seal portions 25b along the length of the vertical frames 13, 14, and prospective seal portions 25c extending in the prospective direction at the end faces of the vertical frames 13, 14 and connecting the horizontal seal portions 25a and vertical seal portions 25b. Similarly, the inner circumferential seal member 26 is endless and has horizontal seal portions 26a extending along the length of the upper frame 11 and lower frame 12, vertical seal portions 26b extending along the length of the vertical frames 13, 14, and prospective seal portions 26c extending in the prospective direction at the end faces of the vertical frames 13, 14 and connecting the horizontal seal portions 25a and the vertical seal portions 25b. The outer circumferential seal member 25 may be a dry seal member known as a rain barrier, the main function of which is to provide watertightness, and the inner circumferential seal member 26 may be a dry seal member known as a wind barrier, the main function of which is to provide airtightness.

[0020] As shown in Figure 14, the transom 15 has a transom main body 15a, an outer sight wall 15b, a lower recessed wall 15c, an inner transom sight wall 15d, a fireproof material support portion 15e, and a transom groove forming wall 15f. The transom main body 15a is flat and slopes downward toward the outside of the room. The outer sight wall 15b extends downward in the sight direction from the edge of the transom main body 15a located on the outside of the room. The lower recessed wall 15c extends downward in the sight direction from the lower edge of the outer sight wall 15b toward the room. The inner transom sight wall 15d extends downward in the sight direction from the edge of the transom main body 15a located on the inside of the room. The distance from the exterior-facing surface of the outer sight wall 15b to the interior-facing surface of the inner sight wall 15d is approximately the same as the distance from the interior-facing surface of the upper inner wall 11b of the upper frame 11 to the exterior-facing surface of the upper outer wall 11c. The fireproofing support 15e extends horizontally toward the interior from approximately the midpoint of the height of the inner sight wall 15d and then bends downward. A panel bracket 15g is attached to the upper surface of the fireproofing support 15e, and a lower fireproof panel accommodating groove 15h is formed between the panel bracket 15g and the upper frame 11, opening upward and facing the upper fireproof panel accommodating groove 11g. The groove-forming wall 15f extends horizontally toward the exterior from approximately the midpoint of the height of the outer sight wall 15b. A transom batten 15i is attached to this transom-forming wall 15f. This transom batten 15i forms an upper panel storage groove 15j that opens upward between itself and the outer sight wall 15b, and forms a lower panel storage groove 15k that opens downward between itself and the outer sight wall 15b. This transom 15 is configured so that its longitudinal dimension is approximately the same as the mutual spacing between the left and right vertical frames 13, 14, and is connected to the left and right vertical frames 13, 14 at a height corresponding to the ceiling panel material C. The above-mentioned upper panel 16 is disposed between the upper panel storage groove 11i of the upper frame 11, the upper panel storage groove 15j of the transom 15, and the vertical panel storage groove 13j of the vertical frames 13, 14, respectively, via upper beat members 16a.Similarly, the lower panel 17 is disposed via lower beat members 17a in the lower panel storage groove 15k of the transom 15, the lower panel storage groove 12g of the lower frame 12, and the vertical panel storage groove 13j of the vertical frames 13 and 14. In addition, a fireproof panel 27 is disposed between the upper fireproof panel storage groove 11g of the upper frame 11, the lower fireproof panel storage groove 15h of the transom 15, and the vertical fireproof panel storage groove 13q of the vertical frames 13 and 14.

[0021] As described above, in this curtain wall 2, as shown in Figures 6 and 7, the outer peripheral sealing member 25 and the inner peripheral sealing member 26 are disposed on the vertical inner peripheral visible wall portion 13e of the vertical frames 13, 14, extending vertically. Therefore, by supporting the curtain wall 2 on the upper floor slab S1 via the mounting bracket 28 with the outer peripheral sealing member 25 and the inner peripheral sealing member 26 abutting against the exterior wall surface 1a of the exterior wall panel 1, a bay window protruding outside beyond the exterior wall surface 1a can be formed while maintaining a tight seal. With this curtain wall 2, the projection dimension of the vertical frames 13, 14 along the projection direction only needs to be such that they protrude from the exterior wall surface 1a of the exterior wall panel 1. In other words, there is no need to provide the vertical frames 13, 14 between the side surfaces of the exterior wall panels 1. This allows the vertical frames 13, 14 to be made smaller, which is advantageous in terms of manufacturing costs.

[0022] Furthermore, when the curtain walls 2 are arranged side by side in the vertical direction, the horizontal seal portion 25a of the outer peripheral seal member 25 and the horizontal seal portion 26a of the inner peripheral seal member 26 extending along the length of the lower frame 12 are abutted against the horizontal seal portion 25a of the outer peripheral seal member 25 and the horizontal seal portion 26a of the inner peripheral seal member 26 extending along the length of the upper frame 11, and the prospective seal portion 25c of the outer peripheral seal member 25 and the prospective seal portion 26c of the inner peripheral seal member 26 extending in the prospective direction at the upper ends of the vertical frames 13, 14 are abutted against the prospective seal portion 25c of the outer peripheral seal member 25 and the prospective seal portion 26c of the inner peripheral seal member 26 extending in the prospective direction at the lower ends of the vertical frames 13, 14, thereby ensuring sealing between them.

[0023] The above-described curtain wall 2 is provided with a ventilation mechanism 30 and a drainage mechanism 40. In this embodiment, the ventilation mechanism 30 is formed by providing a first communication hole 31 and a second communication hole 32 in the left vertical frame 13, and the drainage mechanism 40 is formed by providing a catch pan 41 and a water-blocking member 42 in the left and right vertical frames 13, 14, respectively.

[0024] First, regarding the ventilation mechanism 30, as shown in Figures 7 and 10, the left vertical frame 13 has a first communication hole 31 between the vertical inner sight wall 13g and the indoor-side baffle plate 13t in the vertical outer peripheral projection wall 13h, and a second communication hole 32 between the outdoor-side baffle plate 13t and the vertical outer peripheral projection wall 13h in the vertical main body 13a. As shown in Figures 15 and 16, the first communication hole 31 and the second communication hole 32 are each vertically elongated rectangular openings, and multiple first communication holes 31 and second communication holes 32 are arranged side by side along the top and bottom. As is clear from Figure 15, the upper edge of the opening of the uppermost first communication hole 31 is positioned below the lower edge of the opening of the lowermost second communication hole 32. The first communication hole 31 is covered by the cover portion 13k of the vertical flange 13i described above, making it difficult to see from the outside, but it communicates between the drainage hollow portion 21a and the outside through a gap secured between the cover portion 13k and the outer wall surface 1a of the exterior wall panel 1. A lid 19a that opens and closes the second communication hole 32 is provided on the cover holder 19 of the left vertical frame 13 described above.

[0025] In this ventilation mechanism 30, the drainage hollow portion 21a is always in communication with the outside through the gap between the exterior wall panel 1 and the cover portion 13k of the vertical ridge 13i and the first communication hole 31. When the lid 19a is operated to close the second communication hole 32, the drainage hollow portion 21a is isolated from the room, preventing outside air from entering the room. On the other hand, when the lid 19a is operated to open the second communication hole 32, the drainage hollow portion 21a is in communication with the room through the second communication hole 32 and the slit 18a of the ventilation cover 18, allowing ventilation of the room.

[0026] Meanwhile, with the above-described ventilation mechanism 30, the first communication hole 31 is covered by the cover portion 13k of the vertical ridge 13i. This not only improves the appearance quality, but also eliminates the risk of outside water, such as rainwater, directly falling on the first communication hole 31 and easily entering the drainage hollow portion 21a. Even if water does enter the drainage hollow portion 21a through the first communication hole 31, the second communication hole 32 is located a distance away from the first communication hole 31 in the forward direction and is located higher than the first communication hole 31, so there is no risk of water entering the room through the second communication hole 32. In addition, two baffle plates 13t are provided in the path from the first communication hole 31 to the second communication hole 32 in the drainage hollow portion 21a. Therefore, even if water adheres to the inner wall surface of the vertical outer peripheral projected wall portion 13h or the vertical main body portion 13a, the baffle plate 13t makes it difficult for the water to reach the second communication hole 32. As a result, even in windy and rainy conditions, by opening the lid 19a, ventilation can be performed while preventing water from entering the room.

[0027] The drainage mechanism 40, which drains water from outside the room that has entered through the gap between the exterior wall panel 1 and the outer periphery seal member 25, is constructed by disposing a catch pan 41 and a water-blocking member 42 at the upper ends of the vertical frames 13, 14, and providing drainage holes 43 at the upper ends of the vertical frames 13, 14. The catch pan 41 extends from a portion of the room that is closer to the interior vertical wall 13g between the outer periphery seal member 25 and the inner periphery seal member 26 toward the outside, with its extended edge positioned within the drainage hollow portion 21a. The top surface of the catch pan 41 slopes gradually downward toward the outside. Both sides of the catch pan 41 protrude upward. This catch pan 41 is installed so that when the curtain wall 2 is supported on the floor slab S1 and the outer periphery sealing member 25 and the inner periphery sealing member 26 each abut against the outer wall surface 1a, the edge located on the indoor side is spaced from the outer wall surface 1a, and the gap between the outer wall surface 1a and the catch pan 41 is filled with sealing material 44. The water-blocking member 42 is installed tightly in the drainage hollow portion 21a to prevent water from moving downward, and is located above the upper edge of the opening of the uppermost second communication hole 32. As shown in the figure, the upper surface of the water-blocking member 42 is gradually sloped downward toward the vertical outer periphery projected wall portion 13h. The drainage hole 43 is a through hole provided in the vertical outer peripheral projected wall portion 13h to connect the drainage hollow portion 21a to the outside of the room, and is provided in a position where its lower edge coincides with the upper surface of the water-blocking member 42 and the entire opening is covered by the eave portion 23d provided on the sealing material holder 23.

[0028] In a curtain wall 2 equipped with the drainage mechanism 40, when outside water, such as rainwater, passes between the exterior wall panel 1 and the periphery seal member 25 and enters the interior of the room, or when water enters the drainage hollow portion 21a through the first communication hole 31, the dripping water is received by the catch pan 41 at the upper end of the lower curtain wall 2 and then moves along its slope to the drainage hollow portion 21a of the lower curtain wall 2, reaching the upper surface of the water-blocking member 42. The water is then guided along the slope of the water-blocking member 42 and discharged outside through the drainage holes 43. Therefore, water that passes between the exterior wall panel 1 and the periphery seal member 25 in the upper curtain wall 2 or that enters the drainage hollow portion 21a through the first communication hole 31 will not reach the second communication hole 32 in the lower curtain wall 2, providing an advantage in terms of sealing performance.

[0029] While the above-described embodiment illustrates a curtain wall 2, the present invention can be applied to other building materials as long as they include dry seal members 25, 26 that surround the frame 10. In this case, it is not necessary for both the left and right vertical frames 13, 14 to have vertical seal members 25b, 26b between them and the exterior wall panel 1; it is sufficient for at least one vertical frame to have a vertical seal member. Furthermore, it is not necessary to provide double seal members; at least one of the outer seal member 25 and the inner seal member 26 is sufficient. Furthermore, while the seal members 25, 26 are shown as connecting the horizontal seal members 25a, 26a and the vertical seal members 25b, 26b via the prospective seal members 25c, 26c extending prospectively, the present invention is not limited to this. For example, it is also possible to provide a seal member extending obliquely between the horizontal seal members 25a, 26a and the vertical seal members 25b, 26b to connect them. Furthermore, the upper frame 11 and the vertical frame 12 each have an inclined joint end surface 24, and are connected to the vertical frames 13, 14 via the joint end surface 24, which makes it possible to ensure a large area for the upper panel 16 and the lower panel 17, but this is not necessarily limited to this.

[0030] As described above, the building fixture of the present invention is a building fixture comprising a frame body having upper and lower horizontal frames and left and right vertical frames, and a dry sealing member arranged to surround the periphery of the frame body, wherein the sealing member is arranged on the visible surface facing the room on at least one of the left and right vertical frames, and is characterized by comprising a vertical sealing portion extending along the length of the vertical frame. According to this invention, a bay window can be constructed with the vertical seal portion provided on the visible surface of the vertical frame on the indoor side abutting the exterior wall surface of the building, thereby ensuring sealing without increasing the dimension along the visible direction of the vertical frame, which is advantageous in terms of manufacturing costs.

[0031] The present invention is also characterized in that, in the above-mentioned building fixture, the sealing member is provided on the outer peripheral surface of each of the upper and lower horizontal frames, and has a horizontal sealing portion extending along the length of the horizontal frame, and a prospective sealing portion extending in the prospective direction at the end face of the vertical frame, connecting between the horizontal sealing portion and the vertical sealing portion. According to this invention, the projection seal portion provided on the end face of the vertical frame makes it possible to provide an endless seal member around the frame body.

[0032] Furthermore, the present invention is characterized in that, in the above-mentioned building fixture, the horizontal frame has a joint end surface that is inclined so that the longitudinal dimension gradually decreases toward the interior of the room, and is connected to the end of the vertical frame via the joint end surface.
