Description

Technical Field

[0001] The present invention relates to a vertical frame connection structure in which vertical frames are connected to a gable by a connecting member.

Background Art

[0002] In a horizontally continuous window (horizontal continuous window) in the left - right direction, window portions are arranged side by side in the left - right direction, and vertical frames of the window portions are connected to the gable. The vertical frames are connected to the gable by a connecting member and are held by the gable via the connecting member. Further, regarding such a vertical frame connection structure, conventionally, a sash connection structure for connecting vertical frames of a FIX window to a gable using a support member as a connecting member is known (see Patent Document 1).

[0003] In the conventional sash connection structure described in Patent Document 1, after attaching the support member to the vertical frame with a fixture for the vertical frame, the support member is attached to the gable with a fixture for the gable. However, when wind pressure acts on the vertical frame, the fixture for the vertical frame receives a force in the axial direction of the fixture from the finding portion on the indoor side of the vertical frame and the portion on the outdoor side of the support member. Thus, the fixture for the vertical frame receives the force associated with the wind pressure as a force in the direction of being pulled out from the vertical frame (pull - out direction). Therefore, in the conventional sash connection structure, there is room for improvement from the viewpoint of more stably receiving the force associated with the wind pressure. Also, since it is necessary to first attach the support member to the vertical frame with a fixture for the vertical frame, there is a possibility that the construction may be troublesome, such as being difficult to adjust the fixture for the vertical frame and the support member at the construction site.

[0008] [Figure 1] This is a front view showing the series of windows in this embodiment. [Figure 2] This is a longitudinal cross-sectional view showing the series of windows in this embodiment. [Figure 3] This is a cross-sectional view showing the series of windows in this embodiment. [Figure 4] This is a cross-sectional view showing the vertical frame connecting structure of this embodiment. [Modes for carrying out the invention]

[0009] One embodiment of the vertical frame connecting structure of the present invention will be described with reference to the drawings. The vertical frame connecting structure of this embodiment is a connecting structure for vertical frames to mullions, in which the vertical frames are connected to the mullions by connecting members. The vertical frames are provided on the frame and constitute a part of the frame. In the following, the vertical frame connecting structure will be described using a series of windows (horizontal series windows) in which two or more window sections are arranged in the left-right direction as an example. Therefore, the vertical frames are the vertical frames of the window section frame, and the vertical frame connecting structure is provided on the series of windows. The series of windows, the window sections, and the vertical frame connecting structure are installed on the exterior wall of the building and are positioned between the interior (indoors) and exterior (outdoors) of the building.

[0010] Figure 1 is a front view showing the connected window 1 of this embodiment, showing the connected window 1 installed in building 10 as seen from the interior. Figure 2 is a vertical cross-sectional view showing the connected window 1 of this embodiment, and Figure 3 is a horizontal cross-sectional view showing the connected window 1 of this embodiment. Figures 2 and 3 show a part of building 10 in which the connected window 1 and window section 2 are installed. As shown in the figure, the building 10 has an opening (building opening 12) formed in the exterior wall 11. The continuous window 1 is installed in the building opening 12 and closes the building opening 12.

[0011] When the connected windows 1, window section 2, and vertical frame connecting structure installed in building 10 are viewed from the front, the vertical direction is R, and the horizontal direction is S. In Figure 1, the vertical direction R is the vertical direction, and the horizontal direction S is the horizontal direction. The indoor / outdoor direction T is the indoor / outdoor direction (indoor / outdoor direction) for the connected windows 1, window section 2, and vertical frame connecting structure installed in building 10. Furthermore, the indoor / outdoor direction T is the front-to-back direction when the connected windows 1, window section 2, and vertical frame connecting structure installed in building 10 are viewed from the front, and in Figure 1, it is the horizontal direction perpendicular to the left-to-right direction S. Thus, the directions related to the connected windows 1, window section 2, and vertical frame connecting structure are specified by the direction when they are installed in building 10. Also, the indoor side and outdoor side of the connected windows 1, window section 2, and vertical frame connecting structure refer to the indoor side and outdoor side when they are installed in building 10.

[0012] The connected window 1 comprises multiple (in this case, two) window sections 2 installed side by side in the left-right direction S in a building opening 12 formed in the building 10. The window sections 2 are adjacent to each other in the left-right direction S in the building opening 12 and are connected to the building frame 13 of the building 10 and the mullions 20. The mullions 20 are formed in a hollow shape, extend in the vertical direction R in the building opening 12, and are installed where the left and right window sections 2 are adjacent to each other. The upper and lower ends of the mullions 20 are attached to the building frame 13 of the building 10 by mounting fixtures 30 and 31, respectively.

In this state, the lid portion 51 is positioned along the indoor-outdoor direction T, and acts as a lid for the open portion on the frame opening 3A side of the connecting member 40, thus closing the open portion.

[0042] The cover 50 (here, the lid portion 51) is located on the frame opening 3A side of the connecting member 40, the first fastener 32, and the second fastener 33, and covers the connecting member 40, the first fastener 32, and the second fastener 33 on the frame opening 3A side. The connecting member 40, the first fastener 32, and the second fastener 33 are shielded by the cover 50. In addition, the cover 50 is located between the side portion 21 of the mullion 20 and the protruding portion 7C of the vertical frame 7 in the indoor-outdoor direction T, and is arranged flush with the side portion 21 of the mullion 20. The cover 50 is located on the outdoor side of the side portion 21 of the mullion 20, abuts against the side portion 21, and is arranged continuously with the side portion 21 in the indoor-outdoor direction T.

[0043] In the vertical frame connection structure 9 described above, the force that the vertical frame 7 receives due to wind pressure is transmitted from the connection portion 7E of the vertical frame 7 to the first fixing portion 43 of the connecting member 40 via the first fixing device 32. At this time, the first fixing device 32 receives shear force from the connection portion 7E which is aligned with the indoor-outdoor direction T and the first fixing portion 43 which is aligned with the longitudinal direction of the vertical frame 7. Therefore, the first fixing device 32 and the first fixing portion 43 can stably receive the force associated with wind pressure. In addition, the force that the connecting member 40 receives from the vertical frame 7 is transmitted from the second fixing portion 44 of the connecting member 40 to the connected portion 25 of the mullion 20 via the second fixing device 33. At this time, the second fixing device 33 receives shear force from the connected portion 25 which is aligned with the indoor-outdoor direction T and the second fixing portion 44 which is aligned with the longitudinal direction of the mullion 20. Therefore, the second fixing device 33 and the connected portion 25 can stably receive the force associated with wind pressure.

[0044] When connecting the vertical frame 7 to the mullion 20, the fixings 32, 33 and connecting members 40 can be adjusted and the fixing parts 43, 44 of the connecting members 40 can be fixed while the vertical frame 7 is positioned at the connection point to the mullion 20. Therefore, the vertical frame 7 can be easily connected to the mullion 20 using the connecting members 40. In this way, the vertical frame connection structure 9 can increase its strength against wind pressure and improve its wind pressure resistance, and the construction of the vertical frame connection structure 9 can be made easier. Thus, the wind pressure resistance and constructability of the vertical frame connection structure 9 can be improved.

[0045] During the construction of the vertical frame connection structure 9, the first fastener 32 can be easily fixed to the connection portion 7E of the vertical frame 7 from the frame opening 3A side, and the first fixing portion 43 of the connecting member 40 can be easily connected to the connection portion 7E of the vertical frame 7 by the first fastener 32. In addition, the second fastener 33 can be easily fixed to the connected portion 25 of the mullion 20 from the frame opening 3A side, and the second fixing portion 44 of the connecting member 40 can be easily connected to the connected portion 25 of the mullion 20 by the second fastener 33.

[0046] By engaging the engaging portion 42 of the connecting member 40 with the groove portion 7G of the vertical frame 7, the connecting member 40 can be positioned relative to the vertical frame 7, allowing it to be accurately placed on the vertical frame 7. Furthermore, the connecting member 40 can be stably fixed to the vertical frame 7. By bringing the contact portion 45 of the connecting member 40 into contact with the stepped portion 26 of the mullion 20, the connecting member 40 can be positioned relative to the mullion 20, allowing it to be accurately placed on the mullion 20. Furthermore, the connecting member 40 can be stably fixed to the mullion 20.

[0047] By inserting the clamping portion 7F of the vertical frame 7 between the connecting member 40 and the mullion 20, the vertical frame 7 can be stably connected to the mullion 20. The force received by the vertical frame 7 is transmitted from the clamping portion 7F to the mullion 20 and directly received by the mullion 20. In addition, in the indoor-outdoor direction T, the connecting member 40 receives the protruding portion 7C of the vertical frame 7 with its outdoor surface portion 41, and the mullion 20 receives the contact portion 45 of the connecting member 40 with its stepped portion 26. As a result, the force received by the vertical frame 7 can be stably received by the connecting member 40, and the force received by the connecting member 40 from the vertical frame 7 can be stably received by the mullion 20.

[0048] The cover 50 conceals the connecting member 40, the first fastener 32, and the second fastener 33, thereby improving the aesthetic appearance of the vertical frame connecting structure 9. Furthermore, by positioning the cover 50 flush with the side portion 21 of the mullion 20, the aesthetic appearance of both the side portion 21 of the mullion 20 and the cover 50 can be improved. The connecting portion 7E of the vertical frame 7 to which the first fastener 32 is fixed is positioned along the indoor-outdoor direction T. Therefore, the dimension of the vertical frame 7 in the left-right direction S can be reduced compared to a vertical frame 7 in which the connecting portion 7E is positioned along the left-right direction S.

[0049] Furthermore, the vertical frame connecting structure 9 may be used to connect only one of the left or right vertical frames 7 to the mullion 20. Also, when connecting only one vertical frame 7 to the mullion 20, the vertical frame connecting structure 9 may be used to connect the vertical frame 7 to the mullion 20. The window section 2 is not limited to a stepped window or a fixed window, but may be other window sections (for example, an opening window). The vertical frame 7 is not limited to the vertical frame 7 of the frame body 3 of the window section 2, but may be the vertical frame 7 of other frame bodies 3.
