Description

The present disclosure relates to joinery connection structures.

2. Description of the Related Art Conventionally, when fittings are provided side by side in the left-right direction in an opening of a building, mounting members to which the left and right fittings are respectively fixed are 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 opening in the vertical direction, and has upper and lower ends fixed to the frame of the building. A plurality of piece-shaped anchor members are fixed to the vertical frames of the left and right fittings at intervals in the vertical direction. By fixing the anchor member to the mounting member, the fitting is fixed to the mounting member via the anchor member, and the fittings are connected to each other. In order to increase the strength of the connecting portion between the fittings, it is common to increase the strength of the mounting member by increasing the projected dimension (dimension in the indoor/outdoor direction) of the mounting member toward the indoor side.

In the joinery connecting structure 1 according to the above-described embodiment, the fixing member 5 is a through member that extends substantially over the vertical frames 211 and 212 in the height direction. For this reason, in the fittings connection structure 1 according to the present embodiment, compared to the conventional fittings connection structure in which the members fixed to the vertical frames 211 and 212 and fixed to the mounting members 4 are piece-shaped anchor members, fixing The strength of the member 5 is high. Thereby, both the mounting member 4 and the fixing member 5 can bear the strength of the connecting portion 3 . Therefore, it is not necessary to increase the size of the mounting member 4 in the indoor and outdoor directions in order to increase the strength of the connecting portion 3 . As a result, in the fitting connection structure 1 according to the present embodiment, the mounting member 4 is enlarged in the indoor and outdoor directions, and does not interfere with other parts such as a handle attached to the fitting 2 or degrade the design. The strength of the connection part 3 that connects the fittings 2, 2 can be increased.

In the joinery connecting structure 1 according to the above embodiment, the fixing member 5 is composed 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 fitting connection structure 1 according to the present embodiment, the strength of the fixing member 5 is higher than in the case where the member fixed to the vertical frames 211 and 212 and to the mounting member 4 is one member. Thereby, the fixing member 5 can further bear the strength of the connection part 3, and the strength of the connection part 3 that connects the fittings 2, 2 can be increased.

In the fitting connection structure 1 according to the above-described embodiment, the second fixing member 52 is arranged on the inner peripheral side of the outer peripheral surfaces of the vertical frames 211 and 212 . Therefore, the second fixing member 52 does not protrude outside the outer peripheral surfaces of the vertical frames 211 and 212 . In this embodiment, the second fixing member 52 is arranged in the second hollow portion 262 of the vertical frames 211 and 212 . For this reason, the space inside the vertical frames 211, 212 can be effectively used for connecting the fittings 2, 2, which saves space. It can be fixed strongly.

In the joinery connecting 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 in which the vertical frames 211 and 212 are sandwiched. 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 the screws 81 . Therefore, when the vertical frames 211, 212 and the fixing member 5 are heated by a fire or the like and the vertical frames 211, 212 and the fixing member 5 have different thermal elongations, the vertical frames 211, 212 and the fixing member 5 are directly Deformation can be suppressed compared to the case where it is fixed. If the fittings 2, 2 are fire doors, the fireproof performance can be enhanced.

In the joinery connecting structure 1 according to the above embodiment, the upper end portion 51a of the first fixing member 51 and the upper end portion 52a of the second fixing member 52 are arranged near the upper end portion 4a of the mounting member 4 . The lower end portion 51 b of the first fixing member 51 and the lower end portion 52 b of the second fixing member 52 are arranged near the lower end portion 4 b of the mounting member 4 . That is, the upper end of the fixing member 5 is arranged near the upper end of the mounting member 4 , and the lower end of the fixing member 5 is arranged near the lower end of the mounting member 4 . With such a configuration, the fixing member 5 is provided over substantially the entire vertical direction of the mounting member 4, so that the strength of the connecting portion 3 can be increased.

The present disclosure is not limited to the above embodiments, and can be modified as appropriate. In the above embodiment, the fixing member 5 is two members, the first fixing member 51 fixed to the mounting member 4 and the second fixing member 52 fixed to the first fixing member 51. may be

The form in which the fixing member 5 is fixed to the vertical frames 211 and 212 and the mounting member 4 may be other than the 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-described embodiment, the first fixing member 51 and the second fixing member 52 are fixed by the screws 81 while sandwiching the first vertical frame fixing piece 246 and the second vertical frame fixing piece 247 of the vertical frames 211 and 212. and fixed to vertical frames 211 and 212 . The portions of the vertical frames 211 and 212 sandwiched between 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 and 212 without sandwiching the vertical frames 211 and 212, respectively. The second fixing member 52 may be fixed to the vertical frames 211 and 212, and the first fixing member 51 and the second fixing member 52 may be fixed.

In the above embodiment, the upper end of the fixing member 5 is arranged near the upper end of the mounting member 4 , and the lower end of the fixing member 5 is arranged near the lower end 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.
