A mullion 5 connects the left and right window portions 3A and 3B.
In the following description, the facing direction of the window connecting structure 10 is the X-axis direction, the vertical direction of the window connecting structure 10 is the Y-axis direction, and the viewing direction of the window connecting structure 10 is the Z-axis direction. The X-, Y-, and Z-axis directions are orthogonal to each other.

Although the left and right windows 3A and 3B can be configured by various fireproof windows, they are configured by double sliding windows in the first embodiment. The window portions 3A and 3B are slidingly separated into a window frame 35 composed of an upper frame 31, a lower frame 32, and left and right vertical frames 33, 34 (frame members) formed of extruded aluminum members. It has an outer shoji 36 and an inner shoji 37 that can be installed. The outer shoji 36 and the inner shoji 37 are constructed by arranging a face material 39 such as a glass panel in a shoji frame 38 formed of an extruded aluminum profile.
As shown in FIG. 3, the vertical frames 33 and 34 have projection pieces 331 and 341 along the Z-axis direction, and outdoor extension pieces continuous to the outdoor ends of the projection pieces 331 and 341 along the X-axis direction. It has pieces 332 and 342 and indoor fitting pieces 333 and 343 that are continuous with the indoor ends of the projection pieces 331 and 341 along the X-axis direction. Regulated pieces 335 and 345 extending in the Z-axis direction are formed on the outer peripheral edges of the indoor facing pieces 333 and 343 in the Y-axis direction. Further, fins 336, 346 are formed on the outer peripheral edges of the outdoor tabs 332, 342 so as to extend indoors along the Z-axis direction.

The mullion 5 includes a mounting steel material 51 disposed between the vertical frames 33 and 34 in the X-axis direction, an outdoor holding member 52 that holds the vertical frames 33 and 34 on the outdoor side, and a vertical frame 33 and 34 on the indoor side. The mounting steel member 51 has a restricting body 54 (anchor) that restricts the separation in the X-axis direction (horizontal direction) of the restricted piece portions 335 and 345 of the vertical frames 33 and 34. are mechanically fastened. A fireproof member 55 is installed on the indoor side with respect to the indoor connection member 53, and the fireproof member 55 is screwed to the mounting steel member 51 (in this embodiment, a mounting bracket attached to the mounting steel member 51) with a screw 8 ( mechanically fastened). A square hole is formed in the indoor connection member 53, and the mounting bracket is arranged in this square hole. Screws 6 to 9, which will be described later, are fasteners having heads and shafts (threaded shafts). Alternatively, the fireproof member 55 may be directly screwed and fastened to the mounting steel material 51 by screws 8 without using a mounting bracket. Here, the term "mechanically fastened (fixed)" means mechanically fixed with fasteners (fasteners) such as screws and bolts.

The mounting steel member 51 is made of a metal such as steel, and includes an outdoor front surface portion 511 and an indoor rear surface portion 512 along the X-axis direction, and a front surface portion 511 and a rear surface portion 512 continuous along the Z-axis direction. It has left and right side portions 513 and 514 and is formed to have a substantially rectangular cross section. In this embodiment, the front portion 511 and the rear portion 512 are short sides, and the left and right side portions 513 and 514 are long sides. Upper and lower ends of the mounting steel members 51 are fixed to the building frame 1 via angle members, anchor bolts, and the like.

The outdoor holding member 52 is formed by extruding aluminum so as to extend in the Y-axis direction. It has a holding prospective piece portion 522 extending in the Z-axis direction from 521 toward the indoor side, and an indoor held piece portion 523 extending in the X-axis direction from the indoor end of the holding prospective piece portion 522 . The holding prospective piece portion 522 is screwed (mechanically fastened) to the side portion 514 of the mounting steel material 51 by the screw 6 . The indoor held piece portion 523 is arranged along the rear surface portion 512 of the mounting steel member 51 . The indoor held piece portion 523 is sandwiched between the rear surface portion 512 and the restricting body 54 to increase the mounting strength of the outdoor holding member 52 to the mounting steel member 51 .
