And one panel 6 is fixed to each of them. Here, the skeleton on the upper floor may be the roof, and the skeleton on the lower floor may be the floor on the first floor. The floor 11 of each floor comprises a floor 1, a skeleton 2 supporting the floor, a ceiling 12, etc. The fireproof board 8 is installed between the panel 6 and the floor 11, and the middle floor 3 is provided.
4 and the lower floor 35 are covered with an interlayer covering material 9;
Even if a fire occurs, it has a fire resistant structure that does not easily spread to other floors. Hereinafter, the configuration of the present curtain wall will be described in detail. The cubic member 3 is an extruded product of an aluminum alloy.
As shown in FIG. 2, a plate-shaped fin 13 is provided on the outside of the vehicle, a rail section 14 having a U-shaped cross section is provided on the inside of the room, and a panel mounting portion 15 is provided at the center. A ridge 16 is attached to the panel mounting portion 15, and the ridge 16 and the panel mounting portion 1 are attached.
The side edge of the panel 6 is sandwiched between the outdoor side wall 5 and the side wall 5. The fins 13 have an effect of blocking solar radiation to produce an energy-saving effect, an effect of improving the cross-sectional performance of the cubic material, and a function of reducing the amount of protrusion of the cubic material to the indoor side and expanding the indoor space. The cubic member 3 has the same length as the height of the first floor, and the joint sleeve 17 is inserted into the rail portion 14.
Are connected vertically. As shown in FIG. 1, the connecting portion 18 of the cubic material is located in front of the skeleton 2, and the connecting portion 18 of the cubic material is connected to a fastener 20 attached to a bracket 19 projecting from the skeleton to the outside of the room by a metal fitting 21. ing. The upper and lower blind members 4, 5 are arranged below the connecting portion 18 of the left and right upright members 3, 3 so that the lower upright members 5 are fitted up and down with the lower upright members 5 facing upward. Are fixed to the side surface of the cubic member 3 with angle-shaped fixing brackets 22. Thus, the left and right cubic members 3 and 3 for one floor, the upper blind material 4 erected between the upper end portions of the cubic members, and the lower seamless material erected between the upper end portions of the cubic members for the immediately lower floor A single panel 6 is attached to the opening constituted by 5. A horizontal member 7 is provided between the upper and lower blind members 4 and 5 and on the indoor side of the panel 6 so as to span the left and right cubic members 3 and 3. Both ends of the cross member 7 are fixed to the cubic member 3 by angle-shaped fixing brackets 23. There is a gap between the outdoor surface of the cross member 7 and the indoor surface of the panel 6, and the gap is formed by resilient backup material 25 as shown in FIG. The refractory sealing material 1 is embedded on the backup material 25 while being locked and embedded in the projection 24.
0 and sealed. Further, the horizontal member 7 and the lower blind member 5 are provided with fire-resistant board mounting plates 26 and 27, and the upper and lower ends are fixed to the fire-resistant board mounting plate with screws, and the fire-resistant board 8 is mounted. It is. The side edges of the refractory board 8 are held by holding members 28 provided on the side surfaces of the left and right cubic members 3 in the longitudinal direction. Further, an interlayer sealing material 9 is provided between the indoor side surface of the fireproof board and the outdoor side surface of the floor material. The interlayer sealing material 9
Locking plates 32, 32 each having an L-shaped cross section are fixed to the indoor side surface of the fireproof board 8 and the outdoor side surface of the flooring material 1 so as to face each other. The material 36 is filled. The space between the horizontal member 7 and the floor material 1 is closed by a table board 29, and the upper blind material 4 and the ceiling 1
The space between the two is closed by a blind box 30. Also, an eaves material 31 is attached to the outdoor side of the lower blind material 5,
It prevents strong sunlight from shining into the room. As described above, the present curtain wall has a single panel for the height of the first floor.
The man-hour required for panel mounting can be greatly reduced. Also, after installing the panel, install the fireproof board,
Construction work with the floor, such as installation of interlayer blocking material, can be performed efficiently in an orderly manner. [0011] The curtain wall of the present invention is not limited to the embodiments described herein. The fixing structure of the cubic members to the frame, the structure of the connecting portions between the cubic members, and the position where the connecting portions are to be brought are design matters and can be changed as appropriate. The curtain wall according to the present invention can use a single panel for the height of the first floor, so that the time required for construction is longer than that of the conventional curtain wall in which the panels are vertically divided. Can be greatly reduced, the structure can be simplified, the number of parts can be reduced, and the cost can be reduced. At the same time, the appearance design is improved by reducing the upper and lower seams of the panel. Moreover, since a sufficient fireproof structure is constituted by the fireproof board, the interlayer sealing material, and the fireproof seal, the fire resistance is excellent.
