Claims (6)

1. A vertical frame connecting structure in which vertical frames are connected to mullions by connecting members, The aforementioned vertical frame is arranged along the indoor-outdoor direction and has a connecting portion that connects to the connecting member, The mullion is arranged along the indoor-outdoor direction and has a connecting portion to which the connecting member is connected, The connecting member has a first fixing portion arranged along the longitudinal direction of the vertical frame and fixed to the connecting portion by a first fixing device, and a second fixing portion arranged along the longitudinal direction of the mullion and fixed to the connected portion by a second fixing device . A vertical frame connecting structure that is attached to the connecting member and comprises a cover that covers the connecting member, the first fastener, and the second fastener .
2. In the vertical frame connecting structure described in claim 1, The aforementioned vertical frame is a vertical member that partitions the frame body forming the frame opening, The first fixing portion has a first insertion hole and is positioned on the frame opening side of the connecting portion. The second fixing portion has a second insertion hole and is positioned on the frame opening side of the connected portion. The first fixing device is fixed to the connecting portion with the first insertion hole inserted from the frame opening side, thereby connecting the first fixing portion to the connecting portion. The second fixing device is fixed to the connected portion with the second insertion hole inserted from the frame opening side, thereby connecting the second fixing portion to the connected portion in a vertical frame connecting structure.
3. In the vertical frame connecting structure described in claim 1 or 2, The vertical frame has a groove that extends in the longitudinal direction of the vertical frame, The connecting member is a vertical frame connecting structure having an engaging portion that fits inside the groove and engages with the groove.
4. In the vertical frame connecting structure described in claim 1 or 2, The mullion has a stepped portion extending in the longitudinal direction of the mullion, The connecting member is a vertical frame connecting structure having a contact portion that abuts against the stepped portion and is positioned along the stepped portion.
5. In the vertical frame connecting structure described in claim 1 or 2, The vertical frame is a vertical frame connecting structure having a clamping portion that is sandwiched between the connecting member and the mullion.
6. In the vertical frame connecting structure described in claim 1 or 2 , The cover is a vertical frame connecting structure that is positioned flush with the side surface of the mullion.

Description

This invention relates to a vertical frame connecting structure in which vertical frames are connected to mullions by connecting members. In horizontally aligned windows, the window sections are installed side-by-side, and the vertical frames of the window sections are connected to the mullions. The vertical frames are connected to the mullions by connecting members and are held in place by the mullions via these connecting members. Regarding such vertical frame connection structures, a conventional sash connection structure is known in which a support member, which acts as a connecting member, is used to connect the vertical frames of fixed windows to the mullions (see Patent Document 1). In the conventional sash connection structure described in Patent Document 1, the support member is attached to the vertical frame using a fixing device for the vertical frame, and then the support member is attached to the mullion using a fixing device for the mullion. However, when wind pressure acts on the vertical frame, the fixing device for the vertical frame receives an axial force from the indoor-facing part of the vertical frame and the outdoor-facing part of the support member. Thus, the fixing device for the vertical frame receives the force associated with the wind pressure as a force pulling it out of the vertical frame (pull-out direction). Therefore, the conventional sash connection structure has room for improvement in terms of more stably receiving the force associated with wind pressure. Furthermore, it is necessary to attach the support member to the vertical frame first using the fixing device for the vertical frame, which may make it difficult to adjust the fixing device and support member at the construction site, potentially increasing the time and effort required during installation. Patent No. 5144140 This is a front view showing the series of windows in this embodiment.This is a longitudinal cross-sectional view showing the series of windows in this embodiment.This is a cross-sectional view showing the series of windows in this embodiment.This is a cross-sectional view showing the vertical frame connecting structure of this embodiment. 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. 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. When viewing the connected windows 1, window sections 2, and vertical frame connecting structure installed in building 10 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 sections 2, and vertical frame connecting structure installed in building 10. Furthermore, the indoor/outdoor direction T is the front-to-back direction when viewing the connected windows 1, window sections 2, and vertical frame connecting structure installed in building 10 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 sections 2, and vertical frame connecting structure are specified by their orientation when installed in building 10. Also, the indoor and outdoor sides of the connected windows 1, window sections 2, an
