Description

Technical Field

[0001] The present disclosure relates to a fitting connecting structure.

Background Art

[0002] Conventionally, when fittings are provided side by side in the left-right direction at an opening of a building, a mounting member to which the left and right fittings are respectively fixed is provided between the left and right fittings (see, for example, Patent Document 1). The mounting member is a steel member that extends over the entire vertical direction of the opening, and has an upper end portion and a lower end portion fixed to a building frame. A plurality of piece-shaped anchor members are fixed at intervals in the vertical direction to the vertical frame of each of the left and right fittings. By fixing the anchor members to the mounting member, the fittings are fixed to the mounting member via the anchor members, and the fittings are connected to each other. In order to increase the strength of the connecting portion between fittings, it is common to increase the depth dimension (dimension in the indoor-outdoor direction) of the mounting member toward the indoor side to increase the strength of the mounting member.

The fixing member 5 is, for example, made of steel or aluminum. The fixing member 5 fixed to the fixing portion 24 of the first vertical frame 211 and the fixing member 5 fixed to the fixing portion 24 of the second vertical frame 212 have the same shape and are fixed to the fixing portion 24 of the first vertical frame 211 and the fixing portion 24 of the second vertical frame 212 in a symmetrical orientation in the left-right direction. The fixing member 5 fixed to the fixing portion 24 of the first vertical frame 211 will be described in detail, and the description of the fixing member 5 fixed to the fixing portion 24 of the second vertical frame 212 will be omitted.

[0026] The fixing member 5 comprises a first fixing member 51 and a second fixing member 52. The first fixing member 51 is fixed to the mounting member 4. The second fixing member 52 is fixed to the first fixing member 51. In this embodiment, the fixing member 5 is fixed such that the first fixing member 51 and the second fixing member 52 sandwich the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247, and the first fixing member 51 is fixed to the mounting member 4.

[0027] The first fixing member 51 is a long, L-shaped member that extends vertically. The first fixing member 51 is approximately the same length as the first vertical frame 211, and when fixed to the first vertical frame 211, its upper end 51a is located at a height near the upper end of the first vertical frame 211, and its lower end 51b is located at a height near the lower end of the first vertical frame 211. The first fixing member 51 is a continuous member that extends over approximately the entire height of the first vertical frame 211. The first fixing member 51 has a first fixing piece 511 and a second fixing piece 512. The first fixing piece 511 is flat and is one of the L-shaped cross-sectional shapes of the first fixing member 51.

When the first fixing member 51 is positioned in the above orientation, the second fixing piece 512 protrudes to the other side in the left-right direction from the outdoor-facing edge of the first fixing piece 511.

[0028] The second fixing member 52 is a long, L-shaped member that extends vertically. The second fixing member 52 is approximately the same length as the first vertical frame 211, and when fixed to the first vertical frame 211, its upper end 52a is located at a height near the upper end of the first vertical frame 211, and its lower end 52b is located at a height near the lower end of the first vertical frame 211. The first fixing member 51 is a continuous member that extends almost the entire height of the first vertical frame 211. The second fixing member 52 has a third fixing piece 521 and a fourth fixing piece 522. The third fixing piece 521 is flat and is one of the L-shaped cross-sectional pieces of the second fixing member 52. Third fixed piece 521 The second fixing member 512 is positioned so that its plate surface is the visible surface. The fourth fixing piece 522 is flat and is the other L-shaped piece of the cross-sectional shape of the second fixing member 52. The fourth fixing piece 522 is positioned so that its plate surface is the visible surface. When the second fixing member 52 is positioned in the above orientation, the fourth fixing piece 522 protrudes from the outdoor edge of the second fixing piece 512 to one side in the left-right direction.

[0029] The first fixing member 51 is positioned on the other side in the left-right direction of the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247 of the first vertical frame 211. The first fixing piece 511 is positioned along the other side in the left-right direction of the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. The corner between the first fixing piece 511 and the second fixing piece 512 is positioned along the corner between the first vertical frame fixing piece 246 and the vertical frame intermediate plate portion 243. One side of the second fixing piece 512 in the left-right direction (the part near the corner with the first fixing piece 511) faces the interior side of the vertical frame intermediate plate portion 243 and the interior side of the second protruding piece 249. The other side of the second fixing piece 512 protrudes further to the other side in the left-right direction than the second protruding piece 249. The outdoor end face of the first fixing piece 511 is adjacent in the left-right direction to the indoor surface of the indoor panel portion 242 of the first vertical frame 211.

[0030] The second fixing member 52 is positioned within the second hollow portion of the first vertical frame 211. The second fixing member 52 is positioned on one side in the left-right direction relative to the other side surface 245a of the vertical frame outer plate portion 245. That is, the second fixing member 52 is positioned on the inner side relative to the outer circumferential surface of the first vertical frame 211. The third fixing piece 521 of the second fixing member 52 is positioned along one side in the left-right direction of the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. The fourth fixing piece 522 is positioned along the interior side surface of the vertical frame intermediate plate portion 243. The fourth fixing piece 522 is positioned between the first vertical frame fixing piece 246 and the first protruding piece 248. The corner between the third fixing piece 521 and the fourth fixing piece 522 is positioned along the corner between the vertical frame intermediate plate portion 243 and the first vertical frame fixing piece 246. The outdoor end face of the third fixing piece 521 faces the outdoor surface of the indoor panel portion 242 of the first vertical frame 211 with a gap between them.

[0031] The fixing member 5, positioned as described above with respect to the first vertical frame 211, has a first fixing piece 511 and a third fixing piece 521 that sandwich the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. In this state, the first fixing piece 511 and the third fixing piece 521 are fixed together with a screw 81 from the side of the first fixing piece 511. The first fixing piece 511 and the third fixing piece 521 are fixed together with the screw 81 at a position that overlaps with the groove 263 between the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. In other words, the screw 81 does not penetrate the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. When the screw 81 is fastened, the first fixing piece 511 and the third fixing piece 521 sandwich the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247, respectively, thereby fixing the fixing member 5 to the first vertical frame 211.

[0032] The fixing member 5 is fixed to the first vertical frame 211 as follows. As shown in Figures 4 and 5, the first fixing member 51 and the second fixing member 52 are placed on top of each other so that the first fixing piece 511 and the third fixing piece 521 face each other, and temporarily fastened with screws 81. A gap is left between the first fixing piece 511 and the third fixing piece 521. As shown in Figures 6 and 7, the second fixing member 52 of the first fixing member 52, which is temporarily fastened with screws 81, is inserted from above into the second space 262 of the first vertical frame 211, so that the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247 are sandwiched between the first fixing piece 511 and the third fixing piece 521. The screws 81 are moved along the groove 263 of the first vertical frame 211. Once the fixing member 5 is positioned in the predetermined location, the screws 81 are tightened to firmly sandwich the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247 between the first fixing piece 511 and the third fixing piece 521. In this way, the fixing member 5 is fixed to the first vertical frame 211.

[0033] The vertical frame to which the fixing member 5 is fixed is arranged such that the first fixing piece 511 is positioned along one side surface in the left-right direction of the first side plate portion of the mounting member 4, and the second fixing piece 512 is positioned along the outdoor surface of the mounting outdoor plate portion of the mounting member 4. The indoor end face of the first fixing piece 511 is adjacent to the outdoor surface of the mounting member 4 in the left-right direction. As a result, the indoor surface of the vertical frame indoor plate portion 242 of the vertical frame adjacent to the indoor end face of the first fixing piece 511 is also positioned flush with the indoor surface of the mounting member 4 on the same apparent mounting surface. The other end of the second fixing piece 512 in the left-right direction overlaps approximately the center in the left-right direction of the outdoor surface of the mounting outdoor plate portion 41.

[0034] The first vertical frame 211 and the fixing member 5, positioned on the mounting member 4 as described above, are fixed to the mounting exterior plate portion 41 of the mounting member 4 from the exterior side by screws 82, with the second fixing piece 512 of the first fixing member 51 being fixed to the mounting exterior plate portion 41 of the mounting member 4 from the exterior side. In this way, the first vertical frame 211 is fixed to the mounting member 4 via the fixing member 5. The second vertical frame 212 is also fixed to the mounting member 4 in the same way as the first vertical frame 211. Once the first vertical frame 211 and the second vertical frame 212 are fixed to the mounting member 4 via the fixing member 5, the interior side surfaces of the interior plate portions 242 of the vertical frames of the first vertical frame 211 and the second vertical frame 212, the interior side end faces of the first fixing pieces 511 of the fixing member 5 fixed to the first vertical frame 211 and the second vertical frame 212, and the interior side surface of the mounting member 4 are all arranged flush on the same visible surface. As shown in Figure 2, the upper end 51a of the first fixing member 51 and the upper end 52a of the second fixing member 52 are positioned near the upper end 4a of the mounting member 4. The lower end 51b of the first fixing member 51 and the lower end 52b of the second fixing member 52 are positioned near the lower end 4b of the mounting member 4.

[0035] As shown in Figure 3, the connecting member 6 is positioned along the interior side surfaces of the interior panel portions 242 of the first vertical frame 211 and the second vertical frame 212, the interior side end faces of the first fixing pieces 511 of the fixing members 5 fixed to the first vertical frame 211 and the second vertical frame 212, and the interior side surfaces of the mounting members 4. The connecting member 6 is fixed to the interior panel portions 242 of the first vertical frame 211 and the second vertical frame 212 with screws 83. The connecting member 6 is a C-shaped member and is positioned to extend in the vertical direction. The connecting member 6 is made of, for example, steel or aluminum. The connecting member 6 has a connecting plate portion 61 whose plate surface is the visible surface, and a pair of cover mounting protrusions 62, 62 that protrude inward from the left and right ends of the connecting plate portion 61.

[0036] The connecting plate portion 61 is positioned to overlap with the vertical frame interior plate portion 242, the interior end face of the first fixing piece 511, and the interior face of the mounting member 4. The connecting plate portion 61 is fixed to the first vertical frame 211 and the second vertical frame 212 by screws 83 at positions where it overlaps with the vertical frame interior plate portion 242 of the first vertical frame 211 and the vertical frame interior plate portion 242 of the second vertical frame 212. The connecting plate portion 61 also connects the first vertical frame 211 and the second vertical frame 212. The pair of cover mounting protrusions 62, 62 have claw portions 63 formed near their exterior ends (on the connecting plate portion 61 side) that protrude away from each other in the left-right direction.

[0037] The cover member 7 is a C-shaped profile, positioned to extend vertically. The cover member 7 has an inner cover panel 71, whose surface is the visible surface, and a pair of cover protrusions 72, 72 that project outwards from the left and right ends of the inner cover panel 71. The inner cover panel 71 is formed to be slightly larger in the left-right direction than the connecting panel 61. The pair of cover protrusions 72, 72 are formed to be larger in the in-indoor and out-out directions than the pair of cover mounting protrusions 62, 62. The pair of cover protrusions 72, 72 have claw portions 73 formed on their out-of-door ends, projecting toward each other in the left-right direction. The cover member 7 overlaps the indoor side of the connecting member 6. The cover member 7 is attached to the connecting member 6 by the interlocking of the claw portions 73 of the cover protrusions 72, 72 with the claw portions 63 of the cover protrusions 72, 72 and the claw portions 63 of the cover protrusions 62, 62. The cover interior plate portion 71 and the connecting plate portion 61 are separated and face each other. A fire-resistant member 9 (see Figure 1) is provided between the cover interior plate portion 71 and the connecting plate portion 61.

[0038] In the above embodiment of the joinery connection structure 1, the fixing member 5 is a continuous member that extends substantially over the entire height of the vertical frames 211, 212. Therefore, in the joinery connection structure 1 according to this embodiment, the strength of the fixing member 5 is higher compared to the case of a conventional joinery connection structure in which the member fixed to the vertical frames 211, 212 and fixed to the mounting member 4 is a piece-shaped anchor member. As a result, both the mounting member 4 and the fixing member 5 can bear the strength of the connecting part 3. Therefore, it is not necessary to enlarge the mounting member 4 in the interior-exterior direction to increase the strength of the connecting part 3. Consequently, in the joinery connection structure 1 according to this embodiment, the strength of the connecting part 3 that connects the joinery 2, 2 can be increased without enlarging the mounting member 4 in the interior-exterior direction, without interfering with other parts such as handles attached to the joinery 2, or reducing the aesthetic appearance.

[0039] In the above embodiment of the joinery connection structure 1, the fixing member 5 consists of two members: a first fixing member 51 fixed to the mounting member 4, and a second fixing member 52 fixed to the first fixing member 51. Therefore, in the joinery connection structure 1 according to this embodiment, the strength of the fixing member 5 is higher compared to the case where there is only one member fixed to the vertical frames 211, 212 and fixed to the mounting member 4. As a result, the fixing member 5 can bear an additional burden of strength for the connecting part 3, and the strength of the connecting part 3 that connects the joinery 2, 2 together can be increased.

[0040] In the above embodiment of the joinery connection structure 1, the second fixing member 52 is positioned on the inner side of the outer circumferential surface of the vertical frames 211, 212. Therefore, the second fixing member 52 does not protrude outward from the outer circumferential surface of the vertical frames 211, 212. In this embodiment, the second fixing member 52 is positioned in the second space 262 of the vertical frames 211, 212. Therefore, the internal space of the vertical frames 211, 212 can be effectively utilized for connecting the joinery 2, 2, saving space, and the mounting member 4 and the vertical frames 211, 212 can be fixed with high strength by the fixing member 5.

[0041] In the above embodiment of the joinery connecting structure 1, the first fixing member 51 and the second fixing member 52 are fixed with screws 81 while sandwiching the vertical frames 211 and 212. As a result, the first fixing member 51 and the second fixing member 52 are not directly fixed to the vertical frames 211 and 212 with screws 81. Therefore, if the vertical frames 211 and 212 and the fixing member 5 are heated due to a fire or the like, and the vertical frames 211 and 212 and the fixing member 5 undergo different thermal expansions, deformation can be suppressed compared to the case where the vertical frames 211 and 212 and the fixing member 5 are directly fixed. If the joinery 2,2 is a fire door, the fire resistance performance can be enhanced.

[0042] In the above embodiment of the joinery connection structure 1, the upper end 51a of the first fixing member 51 and the upper end 52a of the second fixing member 52 are positioned near the upper end 4a of the mounting member 4. The lower end 51b of the first fixing member 51 and the lower end 52b of the second fixing member 52 are positioned near the lower end 4b of the mounting member 4. That is, the upper end of the fixing member 5 is positioned near the upper end of the mounting member 4, and the lower end of the fixing member 5 is positioned near the lower end of the mounting member 4. With this configuration, the fixing member 5 is provided over substantially the entire vertical length of the mounting member 4, thereby increasing the strength of the connection portion 3.

[0043] This disclosure is not limited to the embodiments described above and can be modified as appropriate. In the embodiments described above, the fixing member 5 consists of two members: a first fixing member 51 fixed to the mounting member 4 and a second fixing member 52 fixed to the first fixing member 51, but it may consist of one member.

[0044] The form in which the fixing member 5 is fixed to the vertical frames 211, 212 and the mounting member 4 may be other than those described above. In the above embodiment, the first fixing member 51 is fixed to the mounting member 4 with screws 82, but fixing other than screw fixing may be used. In the above embodiment, the first fixing member 51 and the second fixing member 52 are fixed to the vertical frames 211, 212 by screws 81 while sandwiching the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247 of the vertical frames 211, 212. The portion of the vertical frames 211, 212 that is sandwiched by the first fixing member 51 and the second fixing member 52 may be other than those described above. The first fixing member 51 and the second fixing member 52 may be fixed directly to the vertical frames 211, 212, respectively, without sandwiching the vertical frames 211, 212. The second fixing member 52 may be fixed to the vertical frames 211, 212, and the first fixing member 51 and the second fixing member 52 may be fixed.

[0045] In the above embodiment, the upper end of the fixing member 5 is positioned near the upper end of the mounting member 4, and the lower end of the fixing member 5 is positioned near the lower end of the mounting member 4. The positional relationship between the fixing member 5 and the mounting member 4 may be other than that described above, as long as the fixing member 5 is a member that extends in the vertical direction.
