1 comprising a dividing cubic 2 composed of
The framing 5 is constructed by assembling the cubic components 10 and 11 arranged with the waistless eye 4 and the eyeless eyes 3 and 4 therebetween at the factory,
Carry this frame 5 to the construction site and attach it to the building frame,
Further, a glass panel 6 and a waist panel 7 are attached.

At this time, the respective cubic members 10 and 11 are attached to the frame using fasteners or the like (not shown) for each of the frames 5, and the cubic members 10 and 11 which are adjacent to each other and constitute the divided cubic member 2. 11 was usually only engaged to ensure water tightness.

[0004]

However, the mating portions of the cubic members 10 and 11 are provided with an AT material (air tight material, airtight material, seal material) for ensuring the watertightness of the mating portions. As a result, there is a risk that the AT material becomes a resistance of the engagement, and each of the component members swells outward. In addition, the cubic component 1
0 and 11 themselves are warped, and there is a possibility that the divided cubic 2 may be stuck due to the warp.

For this reason, as shown in FIG. 5, the applicants screwed screws 50 into the holding grooves 15 for holding the glass panel 6 and the waist panel 7 of the cubic members 10 and 11, and The directional component members 10 and 11 are connected to each other to form the directional component member 1

However, when such screwing is performed, the holding groove 15, that is, the outside of the cubic members 10, 11 can be prevented from spreading outside, but the inside of the cubic members 10, 11 can be closed by tightening the outside. On the other hand, there is a problem that it spreads outward. In particular, it is difficult to properly set the tightening position of the screw 50 in the screwing, and the screw 50 is often excessively tightened in order to reliably prevent the screw 50 from being entangled. The problem that the side is easy to spread was remarkable. Then, in the division method 2,
When the directional component members 10 and 11 are stuck, the respective directional component members 1
Since a gap is formed between 0 and 11 and the watertightness is reduced, prevention of the watertightness has been required. Further, when the screw 50 is used, there is a problem that on-site workability is deteriorated because screw fixing work must be performed at a construction site.

In addition, depending on the type of window, the holding groove 15
In some cases, a member such as an attachment is attached to the portion in advance, and there is a problem that connection by screwing cannot be used depending on the type of window or the like.
