Description

Technical Field

[0001] The present disclosure relates to a fitting connection 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 each of the left and right fittings is fixed is provided between the left and right fittings (see, for example, Patent Document 1). The mounting member is a steel member extending over the entire vertical direction of the opening, and its upper end and lower end are fixed to the building frame. A plurality of piece - shaped anchor members are fixed to the vertical frames of each of the left and right fittings at intervals in the vertical direction. 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 connection part between the fittings, it is common to increase the expected dimension (dimension in the indoor - outdoor direction) of the mounting member on the indoor side to increase the strength of the mounting member.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the mounting member and a cover member that covers the indoor side of the mounting member may interfere with components such as the handle for opening and closing provided on the fitting when the expected dimension of the mounting member increases on the indoor side. There is a risk that the mounting member and a cover member that covers the indoor side of the mounting member may protrude to the indoor side and the design property may deteriorate.

[0005] An object of the present disclosure is to provide a fitting connection structure capable of increasing the strength of the connection part between fittings without interfering with other components or deteriorating the design property.

Means for Solving the Problems

[0006] To achieve the above object, a fitting connection structure according to the present disclosure includes a pair of fittings provided adjacent to each other in the left-right direction in an opening provided in a wall portion, a mounting member disposed between vertical frames adjacent to each other in the left-right direction of each of the pair of fittings and extending in the vertical direction, and a fixing member extending in the vertical direction and fixed to the vertical frame and fixed to the mounting member. The fixing member includes a first fixing member extending in the vertical direction and fixed to the mounting member, and a second fixing member extending in the vertical direction and fixed to the first fixing member. Moreover, the second fixing member is disposed on the inner side in the left-right direction rather than on the outer side surface in the left-right direction of the vertical frame. 。

The fourth fixing piece 522 is flat and is the other L-shaped piece of the cross-section of the second fixing member 52. The fourth fixing piece 522 is arranged in a direction in which the plate surface becomes the finding surface. When the second fixing member 52 is arranged in the above direction, the fourth fixing piece 522 protrudes from the outdoor-side edge of the second fixing piece 512 to one side in the lateral direction.

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

[0030] The second fixing member 52 is disposed in the second hollow portion of the first vertical frame 211. The second fixing member 52 is disposed on one side in the left-right direction from the surface 245a on the other side in the left-right direction of the vertical frame outer plate portion 245. That is, the second fixing member 52 is disposed on the inner peripheral side rather than the outer peripheral surface of the first vertical frame 211. The third fixing piece 521 of the second fixing member 52 is disposed along the surface on one side in the left-right direction of the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247.

The outdoor-side end surface of the third fixing piece 521 faces the outdoor-side surface of the vertical frame indoor plate portion 242 of the first vertical frame 211 with a gap therebetween.

[0031] The fixing member 5 arranged as described above with respect to the first vertical frame 211 has the first fixing piece 511 and the third fixing piece 521 sandwiching the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. In such a state, the first fixing piece 511 and the third fixing piece 521 are fixed with screws 81 from the side of the first fixing piece 511. The first fixing piece 511 and the third fixing piece 521 are fixed with screws 81 at positions overlapping the groove portion 263 between the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. That is, the screw 81 does not penetrate the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. By tightening the screw 81, 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 FIGS. 4 and 5, the first fixing member 51 and the second fixing member 52 are overlapped so that the first fixing piece 511 and the third fixing piece 521 face each other, and temporarily fixed with screws 81. A gap is provided between the first fixing piece 511 and the third fixing piece 521. As shown in FIGS. 6 and 7, the second fixing member 52 of the first fixing member 51 and the second fixing member 52 temporarily fixed with screws 81 is inserted into the second empty portion 262 of the first vertical frame 211 from above, and 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 screw 81 is moved along the groove portion 263 of the first vertical frame 211. When the fixing member 5 is arranged at a predetermined position, the screw 81 is tightened so that the first fixing piece 511 and the third fixing piece 521 firmly sandwich the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247. 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 along the surface on one side in the left - right direction of the first side plate portion of the mounting member 4, and the second fixing piece 512 is along the outdoor - side surface of the outdoor - side plate portion of the mounting member 4. The indoor - side end face of the first fixing piece 511 is adjacent in the left - right direction to the outdoor - side surface of the mounting member 4. Thereby, the indoor - side surface of the vertical - frame indoor plate portion 242 of the vertical frame adjacent to the indoor - side end face of the first fixing piece 511 is also flush - mounted on the same finding surface as the indoor - side surface of the mounting member 4. The other end in the left - right direction of the second fixing piece 512 overlaps with the approximate center in the left - right direction of the outdoor - side surface of the outdoor - side plate portion 41 of the mounting member 4.

[0034] The first vertical frame 211 and the fixing member 5 arranged as described above with respect to the mounting member 4 are fixed such that the second fixing piece 512 of the first fixing member 51 is screwed to the outdoor - side plate portion 41 of the mounting member 4 from the outdoor side with screws 82. 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 manner as the first vertical frame 211. When the first vertical frame 211 and the second vertical frame 212 are fixed to the mounting member 4 via the fixing member 5, the indoor - side surfaces of the vertical - frame indoor plate portions 242 of the first vertical frame 211 and the second vertical frame 212 respectively, the indoor - 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 respectively, and the indoor - side surface of the mounting member 4 are flush - mounted on the same finding surface. As shown in Figure 2, the upper - end portions 51a of the first fixing member 51 and the upper - end portions 52a of the second fixing member 52 are arranged near the upper - end portion 4a of the mounting member 4. The lower - end portions 51b of the first fixing member 51 and the lower - end portions 52b of the second fixing member 52 are arranged near the lower - end portion 4b of the mounting member 4.

The connecting plate portion 61 is fixed to the first vertical frame 211 and the second vertical frame 212 with screws 83 at positions overlapping with the vertical frame inner plate portion 242 of the first vertical frame 211 and at positions overlapping with the vertical frame inner 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. A pair of cover mounting projecting pieces 62, 62 are formed with claw portions 63 projecting outward in the left and right direction away from each other in the vicinity of the outdoor-side end (on the side of the connecting plate portion 61).

[0037] The cover member 7 is a C-shaped profile member and is arranged in a direction extending vertically. The cover member 7 has a cover inner chamber plate portion 71 whose plate surface serves as the finding surface, and a pair of cover protruding pieces 72, 72 protruding outward from the left and right ends of the cover inner chamber plate portion 71 in the outdoor direction. The cover inner chamber plate portion 71 is formed with a slightly larger dimension in the left-right direction than the connection plate portion 61. The pair of cover protruding pieces 72, 72 are formed with a larger dimension in the indoor-outdoor direction than the pair of cover mounting protruding pieces 62, 62. The pair of cover protruding pieces 72, 72 are formed with claw portions 73 protruding toward the side approaching each other in the left-right direction at the outdoor-side ends. The cover member 7 overlaps the indoor side of the connection member 6. The cover member 7 is attached to the connection member 6 by arranging the pair of cover protruding pieces 72, 72 outside the left and right directions of the pair of cover mounting protruding pieces 62, 62 and engaging the claw portions 73 of the cover protruding pieces 72, 72 with the claw portions 63 of the cover mounting protruding pieces 62, 62. The cover inner chamber plate portion 71 and the connection plate portion 61 face each other with a gap therebetween. A fireproof member 9 (see FIG. 1) is provided between the cover inner chamber plate portion 71 and the connection plate portion 61.

[0038] In the fitting connection structure 1 according to the above embodiment, the fixing member 5 is a continuous member extending substantially over the entire height direction of the vertical frames 211, 212. Therefore, in the fitting connection structure 1 according to the present embodiment, the strength of the fixing member 5 is higher than that of the conventional fitting 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 portion 3. For this reason, in order to increase the strength of the connecting portion 3, it is not necessary to increase the size of the mounting member 4 in the indoor-outdoor direction. As a result, in the fitting connection structure 1 according to the present embodiment, the strength of the connecting portion 3 that connects the fittings 2, 2 to each other can be increased without increasing the size of the mounting member 4 in the indoor-outdoor direction and interfering with other parts such as a handle attached to the fitting 2 or degrading the design.

[0039] The fitting connection structure 1 according to the above embodiment has two members: a first fixing member 51 to which the fixing member 5 is fixed to the mounting member 4, and a second fixing member 52 fixed to the first fixing member 51. Therefore, in the fitting connection structure 1 according to the present embodiment, the member fixed to the vertical frames 211 and 212 and fixed to the mounting member 4 has higher strength than the case where it is a single member. As a result, the fixing member 5 can further bear the strength of the connecting portion 3, and the strength of the connecting portion 3 that connects the fittings 2 and 2 to each other can be increased.

[0040] In the fitting connection structure 1 according to the above embodiment, the second fixing member 52 is disposed on the inner peripheral side rather than the outer peripheral surface of the vertical frames 211 and 212. Therefore, the second fixing member 52 does not protrude outside the outer peripheral surface of the vertical frames 211 and 212. In the present embodiment, the second fixing member 52 is disposed in the second empty portion 262 of the vertical frames 211 and 212. Therefore, the space inside the vertical frames 211 and 212 can be effectively used for connecting the fittings 2 and 2 to each other, saving space, and the mounting member 4 and the vertical frames 211 and 212 can be fixed to each other with high strength by the fixing member 5.

[0041] In the fitting connection structure 1 according to the above embodiment, the first fixing member 51 and the second fixing member 52 are fixed with screws 81 in a state where the vertical frames 211 and 212 are sandwiched therebetween. 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, when 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 have different thermal elongations, deformation can be suppressed compared to the case where the vertical frames 211 and 212 and the fixing member 5 are directly fixed. When the fitting 2 is a fire door, the fire resistance performance can be enhanced.

[0042] In the fitting connection structure 1 according to the above-described embodiment, the upper end portions 51a of the first fixing member 51 and the upper end portions 52a of the second fixing member 52 are arranged in the vicinity of the upper end portion 4a of the mounting member 4. The lower end portions 51b of the first fixing member 51 and the lower end portions 52b of the second fixing member 52 are arranged in the vicinity of the lower end portion 4b of the mounting member 4. That is, the upper end portion of the fixing member 5 is arranged in the vicinity of the upper end portion of the mounting member 4, and the lower end portion of the fixing member 5 is arranged in the vicinity of the lower end portion of the mounting member 4. With such a configuration, since the fixing member 5 is provided substantially over the entire vertical direction of the mounting member 4, the strength of the connecting portion 3 can be increased.

[0043] The present disclosure is not limited to the above-described embodiment and can be changed as appropriate. In the above-described embodiment, the fixing member 5 is composed of two members, namely, the first fixing member 51 fixed to the mounting member 4 and the second fixing member 52 fixed to the first fixing member 51, but it may be a single 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 the above. In the above-described 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-described embodiment, the first fixing member 51 and the second fixing member 52 are fixed to the vertical frames 211, 212 with screws 81 in a state where the first vertical frame fixing pieces 246 and the second vertical frame fixing pieces 247 of the vertical frames 211, 212 are sandwiched therebetween. The portions of the vertical frames 211, 212 sandwiched by the first fixing member 51 and the second fixing member 52 may be other than the above. The first fixing member 51 and the second fixing member 52 may be directly fixed 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-described embodiment, the upper end portion of the fixing member 5 is arranged in the vicinity of the upper end portion of the mounting member 4, and the lower end portion of the fixing member 5 is arranged in the vicinity of the lower end portion of the mounting member 4. As long as the fixing member 5 is a member extending in the vertical direction, the positional relationship with the mounting member 4 may be other than the above.
