In this structure, a supporting piece 3 having a convex cross section is provided in the extending direction of the blind material 2 on the upper part of the outdoor side of the blind material 2 of the curtain wall frame A, and On the lower surface of the lower frame 4 of the frame B, a gripping piece 5 having a downwardly concave cross section corresponding to the support piece 3 is provided in the extending direction of the lower frame 4, and the gripping piece 5 is engaged with the support piece 3. At the same time, a hook-shaped hook piece 7 that opens toward the outdoor side is provided on the upper part of the upper frame 6 on the indoor side of the sash frame B in the extending direction of the upper frame 6, and A hook-shaped bracket 8 that opens toward the indoor side is provided to be fitted to the piece 7, and with the bracket 8 fitted to the hooking piece 7, the bracket 8 is screwed to the blind material 2. The present invention consists in a curtain wall sash mounting structure in which a sash frame B is screwed onto a frame body A, and the sash frame B is easily and quickly attached to a frame body A.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Fig. 1 is a front view of a frame A of a curtain wall, in which mullions 1 and blind members 2 are arranged in a lattice pattern vertically and horizontally, and a sash frame B is placed inside this frame A, that is, within the lattice frame. By further fitting a desired wall panel, glass plate, folding window, etc. into the sash frame B, the outer wall of a building or the like, that is, the curtain wall, is completed. In addition, the frame A is generally made by attaching L-shaped steel to anchor bolts embedded in the end of the floor slab.
A mullion 1 is bolted to it so that it can be attached to a building (not shown).

FIG. 2 is a longitudinal cross-sectional view of the curtain wall frame A, in which the support piece 3 is constructed with the upper end of a vertical wall 10 formed on the outdoor side surface of the blind material 2; A horizontal piece 11 is provided protruding from the inner surface of. On the other hand, the gripping piece 5 is composed of a hanging piece 5a and a channel-shaped piece 5b, and is suspended from the center of the lower surface of the lower frame 4, and a packing 12 is interposed in the channel-shaped piece 5b. Support piece 3
It has come to be combined with

By the way, the lower frame 4 is attached to the upper surface of the blind member 2 as the supporting piece 3 and the gripping piece 5 engage with each other. The hanging pieces 5a abut each other, and the channel-shaped piece 5b as described above is interposed with a packing 12 that contacts the outer surface of the support piece 3.
As the supporting piece 3 and the gripping piece 5 engage, it is possible to both support the lower frame 4 to the blind material 2 and seal it. On the other hand, the indoor end of the lower frame 4 is supported by a blind member 2, and a packing 12 is also interposed thereon. In addition, the lower frame 4
is doubled inside and outside.

In addition, an air intake port 16 is provided in the upright vertical wall 10 of the blank material 2, and the air pressure in the gap between the frame body A and the sash frame B is made equal to the outside pressure.
2, it helps prevent rainwater from entering.

On the other hand, on the indoor side portion of the upper surface of the upper frame 6, a hook-shaped (approximately U-shaped) hook piece 7 that opens toward the outdoor side is provided in a strip in the direction in which the upper frame 6 extends. The head of a hook-shaped (approximately U-shaped) bracket 8 that opens toward the indoor side is fitted and locked onto the stopper 7, and the tail of this bracket 8 is attached to the bottom surface of the blind member 2. It is screwed under the liner 13 with screws 9. An appropriate number of brackets 8 are provided in the longitudinal direction of the hooking piece 7 to ensure that the upper frame 6 is securely fixed. Further, a flange plate 14 with a packing 12 interposed therebetween is attached to the indoor end of the upper frame 6, so that the attachment of the upper frame 6 to the lower surface of the blind material 2 is completed. Furthermore,
A gasket 12 is attached to the upper surface of the central portion of the upper frame 6 so as to be in contact with the outer lower end of the vertical wall 10 of the blind material 2, so that a double seal between the inside and outside similar to that of the lower frame 4 is formed. It's summery.

FIG. 3 is a cross-sectional view of the curtain wall frame A, showing the state in which the mullions 1 and the vertical sash frames 15 are fitted together. The lower frame 4 and the upper frame 6 are made of solid wood 2
However, as mentioned above, since it is securely attached, no special fixing method is adopted here, and the packing 12 that communicates with the inner and outer packing 12 of the lower frame 4 and the upper frame 6 is interposed. , is configured to seal the sash vertical frame 15 inside and outside of the mullion 1.

Now, FIG. 4 is a longitudinal cross-sectional view showing the state in which the sash frame B is attached to the frame body A, and shows that the lower frame 4 is built on the upper surface of the blind material 2, that is, the gripping piece 5 is attached to the supporting piece 3. By engaging the sash frame B, the sash frame B is positioned and supported relative to the frame body A. Also, erect the sash frame B on this frame A in an inclined state, pull the upper part of the sash frame B toward the frame A side in the pivoted state, and attach the head of the bracket 8 to the hooking piece 7 of the upper frame 6. While hooking the part like a key,
The sash frame B is attached to the frame A by fixing the tail portion of the bracket 8 to the lower surface of the blind member 2 with screws. Note that since the bracket 8 is only engaged with the upper frame 6 in a key-like manner at its head, the bracket 8 is engaged with the upper frame 6 in the extending direction of the upper frame 6, in other words, the curtain shown in FIG. In the front view of the wall, it is possible to slide in the left-right direction (in the direction perpendicular to the paper surface in Figure 2), and as a result, even if the frame A of the curtain wall is deformed due to an earthquake or the like, the bracket 8 and the upper frame 6 can be moved. It is also possible to effectively avoid damage to the sash frame B due to sliding between the sash frames B, and of course, with the above-described mounting structure, the sash frame B can be placed inside the frame A. This means that it can be easily installed.

Furthermore, a wall panel or a glass plate is attached to the sash frame B attached to the frame body A in this way to complete a prescribed curtain wall. This shows an example of a window or inlaid window installed on top of this.

Furthermore, as is clear from FIGS. 2 and 3, the sash frame B is attached to the frame A through a double inner and outer packing 12 wrapped around its outer periphery, and the curtain wall is kept free of moisture. Preservation of sex is considered to be more reliable.

In addition, FIG. 5 shows another example of the blind material 2, in which the attachment parts of the upper and lower frames 4 and 6 are box-shaped bodies with a hollow cross section, which increases the robustness. It is being

As is clear from the above description, the curtain wall sash mounting structure according to the present invention includes support pieces with a convex cross section provided on the outdoor side of the blind material, and
