Also, the peripheral side edges of the glass receiving surfaces 5A and 6B of the right vertical frame 1A and the bottom frame 2B (the peripheral side refers to the outer peripheral side of the framed unit. In other words, in this example, the bottom edge of the bottom frame, the right vertical frame ) are formed with flange portions 7 and 8 that protrude from approximately the center of the space toward the outdoors. The flange portions 7 and 8 are formed over substantially the entire length of the flat surfaces 5A and 6B, respectively. As a result, one flange is formed in each of the horizontal joints and vertical joints of adjacent unit frames.

Adjacent vertical frames 1A, 1B and horizontal frames 2A, 2B
Grooves 9 facing each other are formed near the outdoor side of the side edges, and C grooves 10 facing each other are formed near the indoor side of the side edges, and a tight material 11 is fitted into the C grooves 10. to wear When the unit frame is attached to the outer surface of a building, the tight materials 11 are elastically pressed against each other to make the indoor side between the unit frames watertight.

An elastic spacer 12 made of rubber or the like is applied to the above-mentioned face material receiving surfaces 5A, 5B, 6A, and 6B formed on the outdoor side surface of the unit frame, and one sheet is applied to each unit frame through the spacer 12. Attach the facing material 13. At this time, setting blocks 14 (FIG. 2B) are placed on both ends of the flange portion 8 of the lower frame 2B, and the facing material 13 is placed thereon.
