Description

TECHNICAL FIELD The present invention relates to a window connecting structure for connecting two windows aligned in the left-right direction at an opening of a building.

In a horizontal continuous window (horizontal continuous window), a plurality of windows are installed side by side in the horizontal direction at an opening of a building, and two adjacent windows are connected by a window connecting structure. Further, when the windows are fireproof equipment, the two windows are connected to each other by the window connecting structure including the mounting member and the fireproof member. As such a window connection structure, there is conventionally known a window connection structure in which two windows and a fireproof member are attached to a mounting member (mullet) between the two windows (see Patent Document 1).

In the conventional window connection structure described in Patent Document 1, a fireproof member is provided on the indoor side of the mounting member, and the fireproof performance of the window connection structure is improved by the fireproof member. However, the mounting member of the conventional window connecting structure is arranged between the two windows to the outdoor side of the vertical frame and is exposed to the outdoor side of the window. In addition, the distance between the vertical frames of the two windows becomes wider as the mounting member is arranged, and the dimension in the left-right direction of the window connecting structure including the two vertical frames may become larger. When a window part that is a fire prevention facility and a window part that is not a fire prevention facility are arranged across the fire spread line, a difference occurs in the lateral dimension and appearance of each window part connection structure, and the design changes across the fire spread line. Therefore, there is room for improvement in terms of the design of the conventional window connecting structure.
