[0009] [First Embodiment] Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 to 7, the stepped window 10 as a building fixture according to this embodiment is a window provided in an opening of a building to partition the space between the interior and exterior, and is configured with fixed window sections 11 and 12 (FIX window sections) at the top and bottom. In the following description, the left-right direction of the stepped window 10 is defined as the X-axis direction, the up-down direction of the stepped window 10 is defined as the Y-axis direction, and the depth direction of the stepped window 10 is defined as the Z-axis direction. The X, Y, and Z axes are orthogonal to each other.
[0010] The stepped window 10 comprises a window frame 20 (frame body) and facing materials 15, 15 placed inside the window frame 20. The window frame 20 is composed of an upper frame 21, a lower frame 22, left and right vertical frames 23, and a transom 24. The upper frame 21 and lower frame 22 along the X-axis direction and the left and right vertical frames 23 along the Y-axis direction frame the four sides of the stepped window 10, and the transom 24 extends in the X-axis direction at an intermediate position in the Y-axis direction of the stepped window 10 and is connected to the left and right vertical frames 23. In the stepped window 10 of this embodiment, the upper frame 21 and lower frame 22 are the short sides, and the left and right vertical frames 23 are the long sides. The upper frame 21, lower frame 22, left and right vertical frames 23 and transom 24 are frames, with the upper frame 21 constituting the upper frame, the lower frame 22 constituting the lower frame, and the left and right vertical frames 23 constituting the left and right vertical frames. The upper frame 21, lower frame 22, left and right vertical frames 23, and transom 24 are arranged along the periphery of the facing material 15, 15. The upper frame 21, left and right vertical frames 23, and transom 24 hold the facing material 15 at the top of the stepped window 10, while the lower frame 22, left and right vertical frames 23, and transom 24 hold the facing material 15 at the bottom of the stepped window 10. The upper frame 21, lower frame 22, left and right vertical frames 23, and transom 24 have exterior metal members 21A, 22A, 23A, 24A and resin members 21B, 22B, 23B, 24B, 34B, 24C that cover at least the interior facing pieces 213, 223, 233, 243, 343 of the metal members 21A, 22A, 23A, 24A from the interior side. In this embodiment, the metal members 21A, 22A, 23A, and 24A are made of aluminum extruded profiles.
[0011] As shown in Fig. 4, the metal member 21A of the upper frame 21 has a prospective piece portion 211 along the Z-axis direction, an outdoor finding piece portion 212 on the outdoor side extending downward from the prospective piece portion 211, and an indoor finding piece portion 213 on the indoor side extending downward from the prospective piece portion 211 and facing the outdoor finding piece portion 212. The outdoor finding piece portion 212, the indoor finding piece portion 213, and the prospective piece portion 211 constitute a substantially U-shaped face material holding groove 214 (short-side face material holding groove) for holding the upper edge portion of the face material 15. Since this face material holding groove 214 is made of metal and has sufficient strength to hold the face material 15, it is possible to eliminate the need to provide a reinforcing material or the like on the indoor side portion of the face material holding groove 214, thereby reducing costs. Engaging portions 215A with which the resin member 21B is engaged are formed at the lower end portion of the indoor finding piece portion 213 and the indoor-side end portion of the prospective piece portion 211. In the present embodiment, the dimensions of the outdoor finding piece portion 212 and the indoor finding piece portion 213 in the Y-axis direction are equal to each other, and at least half or more of the region facing the spacer 115 in the Z-axis direction described later is the outdoor finding piece portion 212 and the indoor finding piece portion 213. For this reason, the face material 15 is held more firmly in the face material holding groove 214. Further, concave portions 216 along the X-axis direction are formed on the indoor surface of the outdoor finding piece portion 212 and the outdoor surface of the indoor finding piece portion 213, and a sheet-like thermal expansion refractory material 9 is provided along the X-axis direction over the entire length of the upper frame 21 in these concave portions 216. The resin member 21B of the upper frame 21 has a hollow frame-shaped resin frame portion 217 and engaging portions 215B provided on the outdoor-side portion and the indoor-side portion of the resin frame portion 217, respectively, and engaging with the respective engaging portions 215A described above. The resin frame portion 217 forms two hollow portions 218 arranged in parallel in the Z-axis direction, and by forming the hollow portions 218, the heat insulation property of the stepped window 10 is improved. The two hollow portions 218 are formed to have substantially the same size as each other.
[0012] As shown in Figure 5, the metal member 24A of the transom 24 has a hollow frame-shaped metal frame portion 241 that forms three hollow portions 240 and has upper and lower projection portions 2411, 2412 along the Z-axis direction, an outdoor projection portion 242 extending upward from the metal frame portion 241 on the outdoor side, and an indoor projection portion 243 extending upward from the metal frame portion 241 and facing the outdoor projection portion 242 on the indoor side. The outdoor projection portion 242, the indoor projection portion 243, and the projection portion 2411 form a roughly U-shaped panel material holding groove 244 (short-side panel material holding groove) that holds the lower edge of the panel material 15. Since this panel material holding groove 244 is made of metal and has sufficient strength to hold the panel material 15, it is possible to eliminate the need to provide reinforcing materials on the indoor side portion of the panel material holding groove 244, thereby reducing costs. An engaged portion 245A is formed at the upper end of the interior facing piece 243 and the upper interior end of the metal frame portion 241, into which the resin member 24B engages. In this embodiment, the dimensions of the exterior facing piece 242 and the interior facing piece 243 in the Y-axis direction are equivalent, and at least half of the area facing the spacer 115 (described later) in the Z-axis direction is comprised of the exterior facing piece 242 and the interior facing piece 243. As a result, the facing material 15 is held more firmly in the facing material holding groove 244. Furthermore, a concave portion 246 is formed along the X-axis direction on the interior surface of the exterior facing piece 242 and the exterior surface of the interior facing piece 243, and a sheet-like heat-expandable fire-resistant material 9 is provided along the X-axis direction along the entire length of the transom 24 in these concave portions 246. A setting block 8 for receiving the facing material 15 is provided on the facing piece 2411. Furthermore, the metal member 24A has an outdoor-facing piece 342 extending downward from the metal frame 241 on the outdoor side, and an indoor-facing piece 343 extending downward from the metal frame 241 and facing the outdoor-facing piece 342 on the indoor side. The outdoor-facing piece 342, the indoor-facing piece 343, and the projection piece 2412 form a roughly U-shaped panel holding groove 344 (short-side panel holding groove) that holds the upper edge of the panel 15. Since this panel holding groove 344 is made of metal and has sufficient strength to hold the panel 15, it is not necessary to provide reinforcing materials on the indoor side of the panel holding groove 344, thereby reducing costs. The lower end of the indoor-facing piece 343 and the lower indoor end of the metal frame 241 have engaged portions 345A into which the resin member 34B engages. In this embodiment, the dimensions of the exterior facing piece 342 and the interior facing piece 343 in the Y-axis direction are equivalent, and at least half of the area facing the spacer 115 (described later) in the Z-axis direction is comprised of the exterior facing piece 342 and the interior facing piece 343. As a result, the facing material 15 is more firmly held in the facing material holding groove 344. Furthermore, concave portions 346 are formed along the X-axis direction on the interior surface of the exterior facing piece 342 and the exterior surface of the interior facing piece 343, and a sheet-like thermal expansion fire-resistant material 9 is provided along the X-axis direction over the entire length of the transom 24 in these concave portions 346.
[0013] The resin members 24B and 34B of the blind 24 each have a hollow frame-shaped resin frame portion 247 and 347, and engaging portions 245B and 345B provided on the outdoor side portion and the indoor side portion of the resin frame portions 247 and 347 respectively and engaging with the respective engaged portions 245A and 345A described above. The resin frame portions 247 and 347 form two hollow portions 248 and 348 arranged side by side in the Z-axis direction, and by forming the hollow portions 248 and 348, the heat insulation property of the stepped window 10 is improved. The two hollow portions 248 in the resin frame portion 247 are formed such that the one on the outdoor side is larger and the one on the indoor side is smaller, and the two hollow portions 348 in the resin frame portion 347 are formed to be approximately the same size as each other. Further, engaged piece portions 249 and 349 extending indoors are formed at the indoor ends of the resin frame portions 247 and 347, and a resin member 24C of the blind 24 is engaged with the engaged piece portions 249 and 349. The resin member 24C covers the metal frame portion 241 from the indoor side.
[0014] As shown in Figure 6, the metal member 22A of the lower frame 22 is formed in a hollow frame shape by forming hollow portions 2201 and 2202, and has a metal frame portion 221 having an outer peripheral projection portion 2211 and an inner peripheral projection portion 2212 along the Z-axis direction, an outdoor exterior facing portion 222 extending upward from the metal frame portion 221 on the outdoor side, and an indoor interior facing portion 223 extending upward from the metal frame portion 221 and facing the outdoor exterior facing portion 222 on the indoor side. The outdoor exterior facing portion 222, the indoor exterior facing portion 223 and the projection portion 2212 form a roughly U-shaped facing material holding groove 224 (short side facing material holding groove) that holds the lower edge of the facing material 15. Since this facing material holding groove 224 is made of metal and has sufficient strength to hold the facing material 15, it is possible to eliminate the need to provide reinforcing materials on the indoor side portion of the facing material holding groove 224, thereby reducing costs. An engaged portion 225A is formed at the upper end of the interior facing piece 223 and the interior end of the metal frame portion 221, into which the resin member 22B engages. In this embodiment, the dimensions of the exterior facing piece 222 and the interior facing piece 223 in the Y-axis direction are equivalent, and at least half of the area facing the spacer 115 (described later) in the Z-axis direction is comprised of the exterior facing piece 222 and the interior facing piece 223. As a result, the facing material 15 is held more firmly in the facing material holding groove 224. Furthermore, a concave portion 226 is formed along the X-axis direction on the interior surface of the exterior facing piece 222 and the exterior surface of the interior facing piece 223, and a sheet-like thermal expansion fire-resistant material 9 is provided along the X-axis direction over the entire length of the lower frame 22 in these concave portions 226. In addition, the thermal expansion fire-resistant material 9 is also provided on the outer peripheral surface of the facing piece 2212 in the portion that forms the hollow portion 2202. Furthermore, a setting block 8 for receiving the facing material 15 is provided on the projected portion 2212. The resin member 22B of the lower frame 22 has a hollow frame-shaped resin frame portion 227 and engaging portions 225B provided on the outdoor and indoor portions of the resin frame portion 227, which engage with the aforementioned engaged portion 225A. The resin frame portion 227 forms two hollow portions 228 arranged side by side in the Z-axis direction, and the formation of these hollow portions 228 improves the thermal insulation of the stepped window 10. The two hollow portions 228 are such that the one on the outdoor side is larger and the one on the indoor side is smaller.
[0015] As shown in Figure 7, each of the metal members 23A of the left and right vertical frames 23 has a metal frame portion 231 formed in a hollow frame shape and having an outer peripheral projection portion 2311 and an inner peripheral projection portion 2312 along the Z-axis direction, an outer surface projection portion 232 extending in the X-axis direction toward the inner circumference from the metal frame portion 231, and an indoor surface projection portion 233 extending in the X-axis direction toward the inner circumference from the metal frame portion 231 and facing the outer surface projection portion 232. The outer surface projection portion 232, the indoor surface projection portion 233, and the projection portion 2312 form a roughly U-shaped surface material holding groove 234 (long side surface material holding groove) that holds the vertical edges of the surface material 15 of the fixed window portion 11 (see Figure 1, etc.) and the surface material 15 of the fixed window portion 12. The panel material holding groove 234 is made of metal and has sufficient strength to hold the panel materials 15, 15, thus eliminating the need to provide reinforcing materials on the indoor side of the panel material holding groove 234 and reducing costs. Engaged portions 235A are formed on the indoor surface of the indoor facing piece 233 and on the indoor end of the facing piece 2311 of the metal frame portion 231, into which the resin member 23B engages. In this embodiment, the dimensions of the outdoor facing piece 232 and the indoor facing piece 233 in the X-axis direction are equivalent, and at least half of the area facing the spacer 115 (described later) in the Z-axis direction is comprised of the outdoor facing piece 232 and the indoor facing piece 233. Therefore, the upper and lower panel materials 15, 15 are more firmly held in the panel material holding groove 234. Furthermore, recessed portions 236 are formed along the Y-axis direction on the indoor surface of the exterior facing portion 232 and on the inner circumferential surface of the projection portion 2312, and a sheet-like heat-expandable fire-resistant material 9 is provided in these recessed portions 236 along the entire length of the vertical frame 23. Here, the visible piece portion 2312 has an engagement groove portion 2313 formed on the interior side of its concave portion 236, and a metal trim strip 5, made of an aluminum extruded profile in this embodiment, is engaged with this engagement groove portion 2313. The trim strip 5 constitutes the aforementioned interior visible piece portion 233. Each of the resin members 23B of the left and right vertical frames 23 has a hollow frame-shaped resin frame body 237 that forms a hollow portion 2371, and a resin body 238 that is fitted onto the interior facing piece 233 and engages with the resin frame body 237. The resin frame 237 has an engaging portion 235B which is provided on both its exterior and interior sides and engages with each of the aforementioned engaged portions 235A. The resin frame 237 has the aforementioned hollow portion 2371 formed therein, thereby improving the thermal insulation of the stepped window 10. The resin body 238 is formed in the shape of a hollow frame with two hollow sections 2381 and 2382 arranged side by side in the X-axis direction. A fitting section 2383 is formed on the exterior side of the resin body 238, which fits into the interior facing section 233. An engaging section 239 is formed on the interior side of the resin body 238, which extends outward and engages with the resin frame 237. Furthermore, the resin body 238 improves the thermal insulation of the stepped window 10 by forming the aforementioned hollow sections 2381 and 2382.
[0016] The facing materials 15, 15 are each formed in the shape of a rectangular plate, with the top and bottom edges along the X-axis being the shorter sides and the vertical edges along the Y-axis being the longer sides. The facing material 15 has two glass panels 113 and 114 and a spacer 115 placed between the glass panels 113 and 114, with a hollow layer 116 (space) formed between the glass panels 113 and 114 with the spacer 115 in between. Also, a sealing material (sealant) is provided between the glass panels 113 and 114 and around the spacer 115, although this is not shown. Glass panel 113 is made of ordinary glass (float glass) and is positioned on the exterior side relative to glass panel 114. Glass panel 114 is made of heat-resistant tempered glass and is positioned on the interior side relative to glass panel 113. This heat-resistant tempered glass is fire-resistant glass without wires, and its strength is increased by heating and cooling. Because heat-resistant tempered glass is used in the stepped window 10, the view is maintained while fire resistance is enhanced. Since the surface material 15 is constructed in the same way as surface material 15, the same reference numerals as those used for surface material 15 will be used for the construction of surface material 15, and a detailed explanation of its structure will be omitted.
[0017] A sealing section 7 is formed between the aforementioned window frame 20 and the facing materials 15, 15. The sealing section 7 consists of a backup material 71 and an irregularly shaped sealing material 72 provided on the inner circumference side relative to the backup material 71, and is provided between the exterior facing pieces 212, 222, 232, 242, 342 and the glass panel 113, and between the interior facing pieces 213, 223, 233, 243, 343 and the glass panel 114.
[0018] In the stepped window 10 described above, the upper frame 21, the left and right vertical frames 23 and the transom 24, the facing material 15 and the sealing part 7 constitute the fixed window section 11, and the transom 24, the left and right vertical frames 23, the lower frame 22 and the sealing part 7 constitute the fixed window section 12.
[0019] [In case of fire] In the event of a fire, in the stepped window 10 of the first embodiment, each heat-expanding fire-resistant material 9 expands due to heat and seals the gaps between the window frame 20 and the facing material 15. Furthermore, since heat-resistant tempered glass has a high coefficient of linear expansion, when subjected to heat during a fire, it tends to expand in the Y-axis direction, which is along its long side, resulting in a bow-like warp in the Y-axis direction. However, since the interior facing pieces 213, 223, 233, 243, and 343 are made of metal members 21A, 22A, 23A, and 24A, the warping of the facing materials 15, 15 can be suppressed. Furthermore, even if the facing materials 15,15 warp, the irregularly shaped sealing material 72 deforms to follow the warp, thereby suppressing the formation of a gap between the facing materials 15,15 and the window frame 20. Moreover, since the surrounding area of the facing materials 15,15 is surrounded by the heat-expanding fire-resistant material 9, the formation of the aforementioned gap between the facing materials 15,15 and the window frame 20 is further suppressed.
[0020] [Second Embodiment] The stepped window 10B according to the second embodiment of the present invention will be described below. In Figure 8(A) and Figures 9 to 11, the stepped window 10B according to the second embodiment has a vertical sliding window section 11B at its upper part and a fixed window section 12 at its lower part that is substantially the same as that of the first embodiment. The stepped window 10B comprises a window frame 40, a sash 50 positioned at the upper part of the window frame 40, and a facing material 15 similar to that of the first embodiment positioned at the lower part of the window frame 40.
[0021] The window frame 40 comprises an upper frame 41, a lower frame 42, left and right vertical frames 43, and a transom 44, which include a metal member on the exterior side and a resin member on the interior side. The upper frame 41 is formed in a hollow frame shape, and a heat-expandable fire-resistant material 9 is provided on the metal member to close the gap between it and the shoji screen 50 through thermal expansion. Since the lower frame 42 is configured in substantially the same way as the lower frame 22 of the first embodiment, the configuration of the lower frame 42 is appropriately denoted by the same reference numerals as the configuration of the lower frame 22, and a detailed explanation thereof is omitted. The transom 44 differs from the transom 24 of the first embodiment in that it does not have an upwardly extending exterior facing piece 242, but its other configurations are substantially the same as those of the transom 24. Therefore, the same reference numerals as those used for the transom 24 are used for the configuration of the transom 44, and a detailed explanation is omitted. Reinforcement members 441 and 442 are provided in the indoor-side hollow portion 240 and the central hollow portion 240 of the transom 44 to reinforce the transom 44. The reinforcement member 441 has a roughly U-shaped cross-section with the lower piece being longer than the upper piece, and is positioned in the indoor-side hollow portion 240. The reinforcement member 442 has a roughly L-shaped cross-section and is positioned in the central hollow portion 240. The portions of the left and right vertical frames 43 below the transom 44 are configured in substantially the same way as the vertical frame 23 of the first embodiment. The portions of the left and right vertical frames 43 above the transom 44 differ in configuration from the vertical frame 23 of the first embodiment in that the hollow portion of the metal frame 231 extends longer in the Z-axis direction and the hollow portion of the resin member is shorter in the Z-axis direction, and it does not have an exterior facing piece 232, but the other configurations are substantially the same as the vertical frame 23. Therefore, the components of the vertical frame 43 are given the same reference numerals as the components of the vertical frame 23, and a detailed explanation is omitted.
[0022] The shoji screen 50 comprises a frame 55 and a facing material 15 similar to that of the first embodiment, which is placed inside the frame 55, and is connected to the window frame 40 so as to be able to slide outwards toward the exterior. The frame 55 is constructed by assembling an upper frame 51, a lower frame 52, and left and right vertical frames 53. In this embodiment, the upper frame 51 and lower frame 52, which are aligned along the X-axis, are on the short side, and the left and right vertical frames 53 are on the long side. The upper frame 51, lower frame 52, and left and right vertical frames 53 constitute a frame, with the upper frame 51 forming the upper frame, the lower frame 52 forming the lower frame, and the left and right vertical frames 53 forming the left and right vertical frames. The upper frame 51, lower frame 52, and left and right vertical frames 53 are arranged along the periphery of the surface material 15. The upper frame 51, lower frame 52, and left and right vertical frames 53 each have exterior metal members 51A, 52A, 53A and resin members 51B, 52B, 53B that cover at least the interior facing pieces 513, 523, 533 of the metal members 51A, 52A, 53A (described later) from the interior side. In this embodiment, the metal members 51A, 52A, 53A are made of aluminum extruded profiles.
[0023] As shown in Figure 10, the metal member 51A of the upper frame 51 has a metal frame portion 511 which is formed in a hollow frame shape and has a projection portion 5111 on the inner circumference side that is aligned with the Z axis direction, an outdoor facing portion 512 which extends downward from the metal frame portion 511 on the outdoor side, and an indoor facing portion 513 which extends downward from the metal frame portion 511 and faces the outdoor facing portion 512 on the indoor side. The outdoor facing portion 512, the indoor facing portion 513, and the projection portion 5111 form a roughly U-shaped facing material holding groove 514 (short side facing material holding groove) that holds the upper edge of the facing material 15. Since this facing material holding groove 514 is made of metal and has sufficient strength to hold the facing material 15, it is not necessary to provide reinforcing material on the indoor side portion of the facing material holding groove 514, thereby reducing costs. In this embodiment, the dimensions of the exterior facing piece 512 and the interior facing piece 513 in the X-axis direction are equivalent, and at least half of the area of the surface material 15 facing the spacer 115 in the Z-axis direction is comprised of the exterior facing piece 512 and the interior facing piece 513. As a result, the surface material 15 is held more firmly in the surface material holding groove 514. Furthermore, a concave portion 516 is formed along the X-axis direction on the interior surface of the exterior facing piece 512 and the inner circumferential surface of the facing piece 5111, and a sheet-like heat-expandable fire-resistant material 9 is provided in these concave portions 516 along the entire length of the upper frame 51. Here, the visible portion 5111 has an engagement groove 5112 formed on the portion on the interior side of its concave portion 516, and a trim piece 5, similar to that in the first embodiment, is engaged with this engagement groove 5112. The trim piece 5 constitutes the interior visible portion 513 described above. The resin member 51B of the upper frame 51 is fitted and attached to the interior facing piece 513 and engages with the interior side portion of the metal frame 511, and is formed in a hollow frame shape with two hollow portions 518 and 519 arranged side by side in the Y-axis direction. Furthermore, the formation of the aforementioned hollow portions 518 and 519 in the resin member 51B improves the thermal insulation of the stepped window 10B.
[0024] As shown in Figure 10, the metal member 52A of the lower frame 52 has a metal frame portion 521 which is formed in a hollow frame shape and has a projection portion 5211 on the inner circumference side that is aligned with the Z axis direction, an outdoor facing portion 522 which extends upward from the metal frame portion 521 on the outdoor side, and an indoor facing portion 523 which extends upward from the metal frame portion 521 and faces the outdoor facing portion 522 on the indoor side. The outdoor facing portion 522, the indoor facing portion 523, and the projection portion 5211 form a roughly U-shaped facing material holding groove 524 (short side holding groove) that holds the lower edge of the facing material 15. Since this facing material holding groove 524 is made of metal and has sufficient strength to hold the facing material 15, it is not necessary to provide reinforcing materials on the indoor side of the facing material holding groove 524, thereby reducing costs. In this embodiment, the dimensions of the exterior facing piece 522 and the interior facing piece 523 in the X-axis direction are equivalent, and at least half of the area of the surface material 15 facing the spacer 115 in the Z-axis direction is comprised of the exterior facing piece 522 and the interior facing piece 523. As a result, the surface material 15 is held more firmly in the surface material holding groove 524. Furthermore, a concave portion 516 is formed on the interior surface of the exterior facing piece 522 along the X-axis direction, and a sheet-like heat-expandable fire-resistant material 9 is provided in this concave portion 516 along the entire length of the lower frame 52. Here, the visible piece 5211 has an engagement groove 5212 that opens on the inner circumference side, and a retaining strip 5 similar to that in the first embodiment is engaged with this engagement groove 5212. The retaining strip 5 constitutes the interior visible piece 523 described above. The resin member 52B of the lower frame 52 is constructed in substantially the same manner as the aforementioned resin member 51B, and, like the resin member 51B, is designed to improve thermal insulation. The resin member 52B is fitted into the interior facing piece 523 and engages with the interior side portion of the metal frame 521. The detailed description of the resin member 52B is omitted, as it is assigned the same reference numerals as the resin member 51B.
[0025] As shown in Figure 11, the left and right vertical frames 53 are formed in a hollow frame shape and have a metal frame portion 531 with a projection portion 5311 on the inner circumference side that is aligned with the Z-axis direction, an outdoor facing portion 532 extending in the X-axis direction toward the inner circumference from the metal frame portion 531, and an indoor facing portion 533 extending in the X-axis direction toward the inner circumference from the metal frame portion 531 and facing the outdoor facing portion 532. The outdoor facing portion 532, the indoor facing portion 533, and the projection portion 5311 constitute a surface material holding groove 534 (long side surface material holding groove) that holds the vertical edge of the surface material 15. Since this surface material holding groove 534 is made of metal and has sufficient strength to hold the surface material 15, it is not necessary to provide reinforcing materials on the indoor side portion of the surface material holding groove 534, thereby reducing costs. In this embodiment, the dimensions of the exterior facing piece 532 and the interior facing piece 533 in the X-axis direction are equivalent, and at least half of the area of the surface material 15 facing the spacer 115 in the Z-axis direction is comprised of the exterior facing piece 532 and the interior facing piece 533. As a result, the surface material 15 is more firmly held in the surface material holding groove 534. Furthermore, a concave portion 536 along the Y-axis direction is engaged with the interior surface of the exterior facing piece 532 and the inner circumferential surface of the facing piece 5311, and a sheet-like heat-expandable fire-resistant material 9 is provided in this concave portion 536 along the entire length of the vertical frame 53. In addition, the outer circumferential portion of the metal member 53A is provided with a heat-expandable fire-resistant material 9 to close the gap with the vertical frame 43 due to thermal expansion. Here, the visible portion 5311 has an engagement groove 5312 formed on the portion on the interior side of its concave portion 536, and the aforementioned trim piece 5 is engaged with this engagement groove 5312. The trim piece 5 constitutes the aforementioned interior visible portion 533. The resin members 53B of the left and right vertical frames 53 are constructed in substantially the same manner as the aforementioned resin member 51B, and are designed to improve thermal insulation in the same way as the resin member 51B. The resin member 53B is fitted into the interior facing piece 533 and engages with the interior side portion of the metal frame 531. The detailed description of the resin member 53B is omitted, as it is assigned the same reference numerals as the resin member 51B.
[0026] Sealing portions 7 are provided between the window frame 40 and the facing material 15 of the fixed window section 12, and between the frame 55 and the facing material 15, in substantially the same manner as in the first embodiment. The sealing portions 7 consist of a backup material 71 and an irregularly shaped sealing material 72, and are arranged in the same manner as in the first embodiment in the fixed window section 12, and in the vertical sliding window section 11B, they are provided between the exterior facing pieces 512, 522, 532 and the glass panel 113, and between the interior facing pieces 513, 523, 533 and the glass panel 114, respectively.
[0027] In the stepped window 10B described above, the upper frame 41, the left and right vertical frames 43 and the transom 44 and the sash 50 constitute the vertical sliding window section 11B, and the transom 44, the left and right vertical frames 43, the lower frame 42 and the sealing section 7 constitute the fixed window section 12.
[0028] In the stepped window 10B of the second embodiment described above, heat-resistant tempered glass is used for each panel 15, similar to the first embodiment, thereby maintaining the view and enhancing fire resistance. Furthermore, in the event of a fire, the heat-resistant tempered glass of each panel 15 may bend in an arc in the longitudinal direction, the Y-axis direction. However, similar to the first embodiment, the interior facing pieces 513, 523, and 533 are constructed of metal members 51A, 52A, and 53A, thereby improving the fixing strength of the heat-resistant tempered glass and suppressing the bending of each panel 15. Furthermore, even if warping occurs in each of the panel materials 15, the irregularly shaped sealing material 72 deforms to follow the warping, thereby suppressing the formation of gaps between the panel materials 15, 15 and the window frame 40 and frame 55. Moreover, since the periphery of the panel materials 15, 15 is surrounded by the heat-expanding fire-resistant material 9, the formation of the aforementioned gaps between the panel materials 15, 15 and the window frame 40 and frame 55 is further suppressed. Furthermore, the upper frame 51, lower frame 52, and left and right vertical frames 53 of the shoji screen 50 are configured with interior facing pieces 513, 523, and 533 by battens 5 that engage with the surface material holding grooves 514, 524, and 534, making it easy to assemble the surface material 15 and improving workability. In this embodiment, battens 5 are provided on all four frames of the upper frame 51, lower frame 52, and left and right vertical frames 53, but this is not limited to this configuration. Battens 5 may be provided on only three of the frames of the upper frame 51, lower frame 52, and left and right vertical frames 53, and even in this case, it is easy to assemble the surface material 15 and improve workability.
[0029] [Third Embodiment] A third embodiment of the present invention will be described below with reference to the drawings. In Figure 8(B) and Figures 12 to 13, the vertical sliding window 10C as a joinery according to the third embodiment is configured in substantially the same way as the vertical sliding window section 11B of the second embodiment, except that a lower frame 60 is provided instead of a transom 44. For this reason, the same reference numerals as those used for the vertical sliding window section 11B are appropriately used for the vertical sliding window 10C, and their detailed explanation is omitted.
[0030] The lower frame 60 comprises an outdoor metal member 60A and an indoor resin member 60B. In this embodiment, the metal member 60A is made of an aluminum extruded profile and has a hollow frame-shaped metal frame portion 61 and an indoor facing portion 63 extending upward from the metal frame portion 61. The resin member 60B engages with the upper end of the interior facing piece 63 and the interior side portion of the metal frame 61, and covers the interior facing piece 63 from the interior side. In addition, a concave portion 631 is formed on the exterior surface of the interior facing piece 63 along the X-axis direction, and a heat-expandable fire-resistant material 9 is provided in the concave portion 631 along the X-axis direction.
[0031] Here, as shown in Figure 13, a drain hole 56 for draining water is formed at the end of the lower frame 52 of the sash 50 of the vertical sliding window 10C in the X-axis direction, and a roughly U-shaped thermal expansion fire-resistant material 9A is provided around the drain hole 56. The thermal expansion fire-resistant material 9A is provided on both sides in the X-axis direction and on the interior side in the Z-axis direction relative to the drain hole 56. Therefore, in the event of a fire, the thermally expanding fire-resistant material 9A expands, which can seal the drainage holes 56 and prevent flammable gases from leaking from the sealing material of the face material 15. Furthermore, according to the vertical sliding window 10C of the third embodiment, while maintaining the view and enhancing fire resistance, similar to the shoji screen 50 in the second embodiment, the fixing strength of the heat-resistant tempered glass of the facing material 15 can be improved, and warping of each facing material 15 can be suppressed. In addition, even if warping occurs in the facing material 15, the irregularly shaped sealing material 72 deforms to follow the warping, thereby suppressing the formation of a gap between the facing material 15 and the frame 55, thereby suppressing the warping of the facing material 15. Moreover, since the periphery of the facing material 15 is surrounded by the heat-expanding fire-resistant material 9, the formation of the gap between the facing material 15 and the frame 55 is further suppressed.
[0032] [Fourth Embodiment] Embodiments of the present invention will be described below with reference to the drawings. As shown in Figure 8(C), Figures 14 and 15, the sliding window 10D as a building component according to the fourth embodiment comprises a window frame 80 (frame body) and an outer sash 90 and an inner sash 100 arranged to slide open within the window frame 80.
[0033] The window frame 80 is composed of an upper frame 81, a lower frame 82, and left and right vertical frames 83. The upper frame 81 and lower frame 82 are aligned along the X-axis, and the left and right vertical frames 83 are aligned along the Y-axis. The upper frame 81, lower frame 82, and left and right vertical frames 83 each have hollow frame-shaped metal members 81A, 82A, and 83A on the exterior side, and resin members 81B, 82B, and 83B on the interior side that engage with the metal members 81A, 82A, and 83A. In this embodiment, the metal members 81A, 82A, and 83A are made of aluminum extruded profiles. The metal member 81A of the upper frame 81 has an upper rail 811 aligned along the X-axis that fits with the outer sash 90, and a fitting groove 812 aligned along the X-axis that fits with the inner sash 100. The metal member 82A of the lower frame 82 has a projection portion 823 extending in the Z-axis direction and a hollow frame-shaped interior frame portion 824 that is continuous with the interior end of the projection portion 823. A lower rail 821 is formed on the projection portion 823 so that the roller 9212 of the outer sash 90, which will be described later, can be fitted to move in the X-axis direction. The interior frame portion 824 has a rising portion 825 that rises upward from the interior end of the projection portion 823, an upper portion 826 and a lower portion 827 that extend in the Z-axis direction toward the interior from the rising portion 825, and an interior portion 828 that is continuous with the upper portion 826 and the lower portion 827 and extends in the Y-axis direction, with the interior portion 828 extending vertically more than the upper portion 826 and the lower portion 827. A lower rail 822 is formed by raising the vertical section 825 and the upper section 826, into which the roller 9212 of the inner sliding door 100 is fitted so that it can move in the X-axis direction. In addition, the lower frame 82 has an extended section 829 that extends in the Z-axis direction toward the outside from the upper part of the vertical section 825 and has an airtight material attached to its tip that abuts against the lower frame 92. Furthermore, the lower frame 82 is appropriately provided with heat-expandable fire-resistant material 9. This heat-expandable fire-resistant material 9 is provided, for example, on the exterior surface of the rising piece 825, the upper piece 827, and the upper surface of the extended projection piece 829. The heat-expandable fire-resistant material 9 provided on the exterior surface of the rising piece 825 is made of two layers and is arranged so that it can close the gap between the lower frame 82 and the lower frame 92 of the outer sash 90 through thermal expansion. The heat-expandable fire-resistant material 9 provided on the upper piece 827 and the upper surface of the extended projection piece 829 is arranged so that it can close the gap between the lower frame 82 and the lower frame 92 of the inner sash 100 through thermal expansion.
[0034] The outer sliding door 90 comprises a frame 95 and a facing material 15 similar to that of the first embodiment, which is placed inside the frame 95. The frame 95 is composed of an upper frame 91, a lower frame 92, and left and right vertical frames 93 and 94. In this embodiment, the upper frame 91 and lower frame 92, which are aligned along the X-axis, are on the short side, and the left and right vertical frames 93 and 94 are on the long side. The upper frame 91, lower frame 92, and left and right vertical frames 93 and 94 form a frame, with the upper frame 91 forming the upper frame, the lower frame 92 forming the lower frame, and the left and right vertical frames 93 and 94 forming the left and right vertical frames. The upper frame 91, lower frame 92, and left and right vertical frames 93 and 94 are arranged along the periphery of the surface material 15. The upper frame 91, lower frame 92, and left and right vertical frames 93, 94 each have exterior metal members 91A, 92A, 93A, 94A and resin members 91B, 92B, 93B, 94B that cover at least the interior facing pieces 913, 923, 933, 943 of the metal members 91A, 92A, 93A, 94A (described later) from the interior side. In this embodiment, the metal members 91A, 92A, 93A, 94A are made of aluminum extruded profiles.
[0035] As shown in Figure 14, the metal member 91A of the upper frame 91 is formed in a hollow frame shape and has a projection piece 9111 on its inner circumference that is aligned with the Z-axis direction, an outdoor facing piece 912 extending downward from the metal frame 911 on the outdoor side, and a roughly U-shaped facing groove 914 (short-side facing groove) that holds the upper edge of the facing material 15 by the outdoor facing piece 912, the indoor facing piece 913 and the projection piece 9111. The metal frame 911 has a fitting groove 9112 that fits with the upper rail 811 so as to be movable in the X-axis direction. Since the facing groove 914 is made of metal and has sufficient strength to hold the facing material 15, it is not necessary to provide reinforcing materials on the indoor side of the facing groove 914, thereby reducing costs. In this embodiment, the dimensions of the exterior facing piece 912 and the interior facing piece 913 in the Y-axis direction are equivalent, and at least half of the area of the surface material 15 facing the spacer 115 in the Z-axis direction is comprised of the exterior facing piece 912 and the interior facing piece 913. As a result, the surface material 15 is held more firmly in the surface material holding groove. In addition, a sheet-like thermal expansion fire-resistant material 9 is provided on the inner circumferential surface of the facing piece 9111 along the entire length of the upper frame 91, with the X-axis direction aligned. The resin member 91B of the upper frame 91 engages with the lower end of the interior facing piece 913 and also engages with the interior side portion of the metal frame 911, and is formed in a hollow frame shape with a single hollow section 915. Furthermore, the formation of the aforementioned hollow section 915 in the resin member 91B improves the thermal insulation of the sliding window 10D.
[0036] As shown in Figure 14, the metal member 92A of the lower frame 92 has a metal frame portion 921 which is formed in a hollow frame shape and has a projection portion 9211 on the inner circumference side that is aligned with the Z axis direction, an outdoor facing portion 922 which extends upward from the metal frame portion 921 on the outdoor side, and an indoor facing portion 923 which extends upward from the metal frame portion 921 and faces the outdoor facing portion 922 on the indoor side. The outdoor facing portion 922, the indoor facing portion 923, and the projection portion 9211 form a roughly U-shaped facing material holding groove 924 (short side holding groove) which holds the lower edge of the facing material 15. The metal frame portion 921 is provided with a door roller 9212 which fits with the lower rail 821 so as to be movable in the X axis direction. Since the panel material holding groove 924 is made of metal and has sufficient strength to hold the panel material 15, it is not necessary to provide reinforcing materials on the indoor side of the panel material holding groove 924, thereby reducing costs. In this embodiment, the dimensions of the outdoor facing piece 922 and the indoor facing piece 923 in the Y-axis direction are equivalent, and at least half of the area of the panel material 15 facing the spacer 115 in the Z-axis direction is comprised of the outdoor facing piece 922 and the indoor facing piece 923. As a result, the panel material 15 is held more firmly in the panel material holding groove 924. In addition, a sheet-like thermal expansion fire-resistant material 9 is provided along the X-axis direction on the indoor surface of the outdoor facing piece 922 and on the outdoor surface of the indoor facing piece 923, extending along the entire length of the lower frame 92. The metal frame portion 921 has an exterior piece 9213 extending in the Y-axis direction along the exterior facing piece 922, an interior piece 9214 extending in the Y-axis direction along the interior facing piece 923, an inner circumferential facing piece 9211 extending in the Z-axis direction, and an outer circumferential facing piece 9215 extending in the Z-axis direction. The facing pieces 9211 and 9215 extend further inward than the interior piece 9214, and a stepped portion is formed in the middle part of the facing piece 9215 in the Z-axis direction. The metal frame portion 921 also has a pair of opposing pieces 9216 that extend downward from the facing piece 9215 and face the lower rail 821 from both the interior and exterior directions in the Z-axis direction. Furthermore, the metal member 92A is appropriately provided with thermally expanding fire-resistant material 9. This thermally expanding fire-resistant material 9 is provided, for example, on the outer circumferential surface of the projection piece 9215 that is on the indoor side of the pair of opposing pieces 9216 and faces the lower frame 82 in the Y-axis direction, on the inner circumferential surface of the projection piece 9215 that is on the indoor side of the pair of opposing pieces 9216 and faces the resin member 92B in the Y-axis direction, and on the surface of the pair of opposing pieces 9216 that faces the lower rail 821, and is arranged so as to be able to close the gap between the metal member 92A and the lower frame 82 and the gap between the resin member 92B through thermal expansion. The resin component 92B of the lower frame 92 is formed in a hollow frame shape with two hollow sections 925 and 926, and engages with the upper end of the interior facing piece 923 and the interior side portion of the metal frame 921. By forming the hollow sections 925 and 926 in this resin component 92B, the thermal insulation of the sliding window 10D is improved.
[0037] As shown in Figure 15, one of the left and right vertical frames 93 constitutes the door edge frame, and the other left and right vertical frame 94 constitutes the outer meeting frame. The metal member 93A of the vertical frame 93 as the door edge frame has a metal frame portion 931 which is formed in the shape of a hollow frame and has a projection portion 9311 on the inner circumference side that is aligned with the Z axis direction, an exterior facing portion 932 which extends from the metal frame portion 931 toward the inner circumference in the Y axis direction, and an interior facing portion 933 which extends from the metal frame portion 931 toward the inner circumference in the Y axis direction and faces the exterior facing portion 932 on the interior side. The exterior facing portion 932, the interior facing portion 933 and the projection portion 9311 constitute a surface material holding groove 934 (long side surface material holding groove) which holds the vertical edge of the surface material 15. Since the panel material holding groove 934 is made of metal and has sufficient strength to hold the panel material 15, it is not necessary to provide reinforcing materials on the indoor side of the panel material holding groove 934, thereby reducing costs. In this embodiment, the dimensions of the outdoor facing piece 932 and the indoor facing piece 933 in the X-axis direction are equivalent, and at least half of the area of the panel material 15 facing the spacer 115 in the Z-axis direction is comprised of the outdoor facing piece 932 and the indoor facing piece 933. As a result, the panel material 15 is held more firmly in the panel material holding groove 934. In addition, a sheet-like thermal expansion fire-resistant material 9 is provided on the inner circumferential surface of the facing piece 9311 along the entire length of the vertical frame 93, oriented in the Y-axis direction. Furthermore, the outer circumferential portion of the metal member 93A is provided with a thermal expansion fire-resistant material 9 to close the gap with the vertical frame 83 due to thermal expansion. The resin component 93B of the vertical frame 93 is formed in a hollow frame shape with two hollow sections 935 and 936, and engages with the inner circumferential end of the interior facing piece 933 and the interior side portion of the metal frame 931. By forming the hollow sections 935 and 936 in this resin component 93B, the thermal insulation of the sliding window 10D is improved.
[0038] The metal member 94A of the vertical frame 94 as an exterior meeting frame has a metal frame portion 941 which is formed in a hollow frame shape with two hollow portions 940 aligned in the Z-axis direction and has a projection portion 9411 on the inner circumference side that is aligned in the Z-axis direction, an exterior facing portion 942 which extends in the Y-axis direction toward the inner circumference from the metal frame portion 941, and an interior facing portion 943 which extends in the Y-axis direction toward the inner circumference from the metal frame portion 941 and is opposite to the exterior facing portion 942. The exterior facing portion 942, the interior facing portion 943, and the projection portion 9411 constitute a facing material holding groove 944 (long side facing groove) that holds the vertical edge of the facing material 15. Since this facing material holding groove 944 is made of metal and has sufficient strength to hold the facing material 15, it is not necessary to provide reinforcing materials on the interior side of the facing material holding groove 944, thereby reducing costs. In this embodiment, the dimensions of the exterior facing piece 942 and the interior facing piece 943 in the X-axis direction are equivalent, and at least half of the area of the surface material 15 facing the spacer 115 in the Z-axis direction is comprised of the exterior facing piece 942 and the interior facing piece 943. As a result, the surface material 15 is more firmly held in the surface material holding groove 944. In addition, a sheet-like thermal expansion fire-resistant material 9 is provided on the inner circumferential surface of the facing piece 9411 along the entire length of the vertical frame 94, oriented in the Y-axis direction. Furthermore, a thermal expansion fire-resistant material 9 is appropriately provided on the interior side portion of the metal member 94A to seal the gap with the inner sash 100 due to thermal expansion. Furthermore, the two hollow sections 940 are provided with reinforcing members 9412 and 9413, which have a roughly U-shaped cross-section and reinforce the vertical frame 94, and are screwed to the leading piece 9411. Reinforcing member 9412 is located in the hollow section 940 on the indoor side, and reinforcing member 9413 is located in the hollow section 940 on the outdoor side. In Figure 15, the right side piece of the indoor reinforcing member 9412 along the Z-axis is shorter than the left side piece along the Z-axis, and the right side piece of the outdoor reinforcing member 9413 along the Z-axis is longer than the left side piece along the Z-axis. The resin member 94B of the vertical frame 94 is engaged with the interior facing piece 943 and partially covers the interior facing piece 943 from the interior side. By positioning this resin member 94B in the space on the interior side of the metal member 94A, the thermal insulation of the sliding window 10D is improved.
[0039] Between the frame 95 and the facing material 15, as described above, a sealing section 7 is provided, similar in general to the shoji screen 50 of the second and third embodiments. The sealing section 7 is composed of a backup material 71 and an irregularly shaped sealing material 72, and is provided between the metal members 91A, 92A, 93A, 94A and the glass panel 113 of the facing material 15, and between the metal members 91A, 92A, 93A, 94A and the glass panel 114 of the facing material 15.
[0040] The interior shoji screen 100 is positioned on the interior side relative to the exterior shoji screen 90. Although it may differ in shape and size from the exterior shoji screen 90, it is generally constructed in the same manner, except that it has an interior meeting stile instead of an exterior meeting stile. Therefore, for the interior shoji screen 100 that is generally the same as the exterior shoji screen 90, the same reference numerals are used as appropriate, and detailed explanations are omitted.
[0041] In the interior sliding door 100, the upper frame 91 is fitted to the fitting groove 812 of the upper frame 81 so as to be movable in the X direction, the lower frame 92 is fitted to the lower rail 822 of the lower frame 82 so as to be movable in the X direction, one of the left and right vertical frames 93 constitutes the door edge frame, and the other left and right vertical frame 130 constitutes the meeting frame.
[0042] Here, the vertical frame 130, which is an interior meeting frame, comprises an exterior metal member 130A and a resin member 130B that covers at least the interior facing piece 133 of the metal member 130A (described later) from the interior side. The metal member 130A is formed in the shape of a hollow frame with two hollow portions 140 aligned in the Z-axis direction and has a metal frame portion 131 with a projection portion 1301 on the inner circumference side that is aligned in the Z-axis direction, an exterior facing portion 132 extending in the Y-axis direction toward the inner circumference from the metal frame portion 131, and an interior facing portion 133 extending in the Y-axis direction toward the inner circumference from the metal frame portion 131 and facing the exterior facing portion 132 on the interior side. The exterior facing portion 132, the interior facing portion 133, and the projection portion 1301 constitute a facing material holding groove 134 (long side material holding groove) that holds the vertical edge of the facing material 15. Sealing portions 7 are provided between the exterior facing portion 132 and the glass panel 113 and between the interior facing portion 133 and the glass panel 114, in substantially the same manner as the outer sash 90. Since the panel material holding groove 134 is made of metal and has sufficient strength to hold the panel material 15, it is not necessary to provide reinforcing materials on the indoor side of the panel material holding groove 134, thereby reducing costs. In this embodiment, the dimensions of the outdoor facing piece 132 and the indoor facing piece 133 in the X-axis direction are the same, and at least half of the area of the panel material 15 facing the spacer 115 in the Z-axis direction is comprised of the outdoor facing piece 132 and the indoor facing piece 133. As a result, the panel material 15 is held more firmly in the panel material holding groove 134. In addition, a sheet-like thermal expansion fire-resistant material 9 is provided on the inner circumferential surface of the facing piece 1301 along the entire length of the vertical frame 130, oriented in the Y-axis direction. Furthermore, reinforcing members 141 and 142 that reinforce the vertical frame 130 are provided in the two hollow sections 140 by being screwed to the projection section 1301. Reinforcing member 141 is located in the hollow section 140 on the indoor side, and reinforcing member 142 is located in the hollow section 140 on the outdoor side. In Figure 15, the indoor reinforcing member 141 is formed in a roughly L-shape in cross-section, and the outdoor reinforcing member 142 is formed in a roughly U-shape in cross-section. In Figure 15, the left side piece of the outdoor reinforcing member 142 along the Z-axis is formed to be longer than the right side piece along the Z-axis. The resin member 130B is formed in a hollow frame shape with two hollow sections 135 and 136, and engages with the inner circumferential end of the interior facing piece 133 and the exterior and interior portions of the metal frame 131. This resin member 130B covers the interior facing piece 133 and the interior portion of the metal frame 131 from the interior side, as well as the outer circumferential portion of the metal frame 131, and the formation of the hollow sections 135 and 136 improves the thermal insulation of the sliding window 10D.
[0043] According to the sliding window 10D of the fourth embodiment, while maintaining the view and enhancing fire resistance, similar to the sash 50 in the second and third embodiments, the fixing strength of the heat-resistant tempered glass of each panel 15 can be improved, and warping of each panel 15 can be suppressed. Furthermore, even if warping occurs in each panel 15, the irregularly shaped sealing material 72 of the sealing part 7 deforms to follow the warping, thereby suppressing the formation of gaps between each panel 15 and the frame 95, thereby suppressing warping of the panel 15. Moreover, since the periphery of the panel 15 is surrounded by the heat-expanding fire-resistant material 9, the formation of the gap between the panel 15 and the frame 95 is further suppressed.
[0044] [Differentiation] In each of the embodiments described above, the indoor-side glass panel 114 of the facing material 15 is made of heat-resistant tempered glass, but the invention is not limited to this, and the outdoor-side glass panel 113 may also be made of heat-resistant tempered glass. In this case, the indoor-side glass panel 114 may also be made of ordinary glass. In each of the above embodiments, the surface material 15 is a double-layered glass having glass panels 113 and 114, but it may also be a multi-layered glass having three or more layers, or it may be a surface material made of a single layer of heat-resistant tempered glass. In each of the above embodiments, irregularly shaped sealing material 72 is provided between the exterior facing pieces 132, 212, 222, 232, 242, 342, 512, 522, 532, 542, 912, 922, 932, 942 and the facing material 15, and between the interior facing pieces 133, 213, 223, 233, 243, 343, 513, 523, 533, 543, 913, 923, 933, 943 and the facing material 15, but is not limited to this. For example, an irregularly shaped sealing material 72 may be provided between the exterior facing pieces 132, 212, 222, 232, 242, 342, 512, 522, 532, 542, 912, 922, 932, 942 and the facing material 15, or between the interior facing pieces 133, 213, 223, 233, 243, 343, 513, 523, 533, 543, 913, 923, 933, 943 and the facing material 15, while a standard sealing material such as a gasket (not shown) may be provided on the other side. In each of the above embodiments, the thermally expanding fire-resistant material 9 is provided in the panel material holding grooves 134, 214, 224, 234, 244, 344, 514, 524, 534, 544, 914, 924, 934, and 944, but is not limited to this. For example, the thermally expanding fire-resistant material 9 is provided along the longitudinal direction of the long-side panel material holding grooves 134, 234, 534, 934, and 944 along the long side (vertical edge side in each embodiment) of each panel material 15, and the thermally expanding fire-resistant material 9 in the short-side panel material holding grooves 214, 224, 244, 344, 514, 524, 544, 914, and 924 along the short side (horizontal edge side in each embodiment) of each panel material 15 may be omitted. In this case, even if the heat-resistant tempered glass of the panel 15 warps in an arc on its long side during a fire, the short side of the heat-resistant tempered glass will hardly warp at all. Therefore, the thermal expansion fire-resistant material 9 provided in the long-side panel holding grooves 134, 234, 534, 934, 944 will expand due to heat, which will prevent gaps from forming between each panel 15 and the window frames 20, 40, 80 and the frame members 55, 95. The drainage holes 56 and the heat-expanding fire-resistant material 9 in the third embodiment may also be provided in the lower frame 52 in the second embodiment. In the first embodiment, the transom 24 is not provided with the reinforcing members 441 and 442 that are placed in the hollow portion 240 of the transom 44 in the second embodiment, but the reinforcing members 441 and 442 may be provided in substantially the same manner as in the second embodiment. In each of the above embodiments, the interior facing pieces 133, 213, 223, 233, 243, 343, 513, 523, 533, 543, 913, 923, 933, and 943 may be formed by a trim piece 5 that engages and connects with the metal members 130A, 21A, 22A, 23A, and 24A, or they may be formed integrally and continuously with the metal members 130A, 21A, 22A, 23A, and 24A.
[0045] [Summary of the invention] (1) The joinery of the present invention is a joinery in which a frame is disposed around the periphery of a facing material, wherein the facing material has heat-resistant tempered glass which is fire-resistant glass without wires, and the frame has a metal member which is formed by a facing material holding groove having an exterior facing piece on the exterior side, an interior facing piece on the interior side and a projection piece, and a resin member which covers at least the interior facing piece from the interior side, and an irregularly shaped sealing material is provided between at least one of the interior facing piece and the exterior facing piece and the facing material. According to the building components of the present invention, by employing heat-resistant tempered glass, it is possible to maintain the view while exhibiting fire resistance and reducing costs compared to cases where wired glass or heat-resistant crystallized glass is employed. Furthermore, by constructing the interior facing portion from a metal component, it is possible to suppress warping due to thermal expansion that may occur in the heat-resistant tempered glass during a fire, compared to cases where the interior facing portion is made from a resin component, and it is also possible to eliminate the need to provide reinforcing material on the interior side of the surface material holding groove. Moreover, since the interior facing portion formed from a metal component is covered with a resin component, it is possible to suppress the reduction in the thermal insulation performance of the building components that would occur if the interior facing portion were made from a metal component. In addition, by providing an amorphous sealing material between at least one of the interior and exterior facing pieces and the surface material, the fixing strength of the surface material can be increased compared to gaskets, and even if the heat-resistant tempered glass warps, the amorphous sealing material will deform to follow, thus maintaining fire resistance between at least one of the interior and exterior facing pieces and the surface material. (2) In the joinery of the present invention, the facing material has a short side and a long side, and a heat-expandable fire-resistant material may be provided along the long side material holding groove located on the long side side of the facing material holding groove. With this configuration, the heat-resistant tempered glass of the facing material may warp in its longitudinal direction when heated during a fire. However, the heat-expanding fire-resistant material provided along the long-side material retaining groove expands due to heat, which can suppress the formation of gaps between the facing material and the frame on the long side, thereby improving fire resistance. Furthermore, since heat-resistant tempered glass is less prone to warping on the short side during a fire, and can maintain sufficient fire resistance with amorphous sealant, it is not necessary to provide heat-expanding fire-resistant material in the short-side side material retention grooves located on the short side of the panel material, thereby reducing costs while maintaining fire resistance. (3) In the building fittings of the present invention, the facing material comprises at least two glass panels, including the heat-resistant tempered glass, and a sealing material is provided between the two glass panels. The frame is composed of an upper frame, a lower frame, and left and right vertical frames. The lower frame has drainage holes for draining water. The three facing material holding grooves on the upper frame and the left and right vertical frames are provided with heat-expandable fire-resistant material along their entire length. The facing material holding grooves of the lower frame may also be provided with heat-expandable fire-resistant material to seal the drainage holes. With this configuration, in the event of a fire, the heat-expandable fire-resistant material expands in the three face material retention grooves of the upper frame and the left and right vertical frames, sealing the periphery of the face material along the entire length of the three frames, and the heat-expandable fire-resistant material expands in the face material retention groove of the lower frame, sealing the drainage holes. This suppresses the generation of flammable gas from the sealing material, for example, when the heat-resistant tempered glass warps. Furthermore, in the lower frame, the heat-expandable fire-resistant material seals the drainage holes due to thermal expansion, thus suppressing the leakage of the flammable gas. (4) In the joinery of the present invention, the frame is composed of an upper frame, a lower frame, and left and right vertical frames, and the interior facing portion of at least three of the upper frame, lower frame, and left and right vertical frames may be a trim that engages with the surface material holding groove. With this configuration, the fixing strength of the heat-resistant tempered glass is increased by constructing the interior facing portion from a metal member, while the ease of assembling the joinery is also improved by using a batten for the interior facing portion on at least three sides of the frame. (5) In the building fittings of the present invention, the facing material comprises at least two glass panels, including the heat-resistant tempered glass, and the heat-resistant tempered glass may be positioned on the interior side relative to the other glass panels. With this configuration, for example, if the fixtures are installed at a high place in a building, even if the heat-resistant tempered glass breaks, it will fall inward instead of outward, thus maintaining safety.
