[Example] As shown in Fig. 1, a large beam 1 on a steel frame or the like
The upper wall plate 2 such as RC plate, PC plate, ALC plate, etc. is attached to the upper building frame 3 and the RC plate is attached to the girder 4 such as a steel frame.
A lower wall plate 5 such as a PC plate and an ALC plate is attached to form a lower building frame 6, and the upper building frame 3 and the lower building frame 6 are attached.
A sash frame A is attached over the entire length.

The sash frame A is a rectangular frame composed of an upper frame 10, a lower frame 11, and left and right vertical frames 12, and the upper frame 10 is connected to an upper wall plate 2 by an anchor 13, and the lower frame 11 is a lower wall. It is connected to the plate 5 by an anchor 14.

As shown in FIG. 2, the upper frame 10 has a cross-sectional shape in which an upward groove 21 and a door stop 22 are integrally provided on the indoor side of a main body 20 having a hollow cross-section. As shown in FIGS. 2 and 3, the horizontal piece 23 and the both-side vertical pieces 2

It is slidably fitted in the inside thereof in the longitudinal direction, and the streak 27 is welded and fixed to the fixing piece 26. The anchor 14 of the lower frame 11 is the same as the conventional one.

Because of this, when the upper building frame 3 is interlayer displaced in the direction of arrow a and the lower building frame 4 is displaced in the direction of arrow b, the sash frame A moves in the direction of arrow b together with the lower building frame 6, and the sash frame Since the upper frame 10 of A slides in the in-plane direction with respect to the anchor 13 to absorb the interlayer displacement, the sash frame A does not deform.

Moreover, since the upper frame 10 and the anchor 13 do not move relative to each other in the out-of-plane direction, the upper frame 10 does not move in the out-of-plane direction due to strong wind and rain acting on the shoji attached to the sash frame A.

Further, the anchor 13 can be manufactured at a low cost by using a sheet metal, and it suffices to be fitted in the upward groove 21 of the upper frame 10 and welded to the streak 27, so that special work is not required and complicated work is unnecessary. Then, the upper frame 10 can be mounted in the same manner as a normal anchor mounting.

Next, a second embodiment of the present invention will be described. FIG.
As shown in FIG. 5, the upper frame 10 constituting the sash frame A has a cross section having an upward recess 31 by detachably attaching the ridge 30 to the outdoor side of the body 20 having a hollow cross section, and the horizontal piece 33 of the upper fastener 32. Is the fastener 34 with the upper building frame 3
The circular end 35a of the vertical piece 35 of the upper fastener 32 is fitted into the upward recess 31, the upper portion of the main body 20 is separated from the inner surface of the upper building body 3, and the sealing material 36 is mounted between them. I am doing it.

Because of this, when the upper building frame 3 and the lower building frame 6 are displaced between layers, the upper frame 10 and the lower frame 11 are in the in-plane direction relative to the upper building frame 3 and the lower building frame 6. The sash frame A is not deformed by moving and absorbing interlayer displacement.

When the upper building body 3 and the lower building body 4 relatively move in the out-of-plane direction, the upper frame 10 and the lower frame 11 are oscillated and displaced with respect to the upper fastener 32 and the lower fastener 38 in the out-of-plane direction. Absorb relative movement in the outward direction.

Next, a method of mounting the sash frame A shown in FIG. 4 will be described. The upper fastener 32 and the lower fastener 38 are fixed to each other, and with the ridge 30 removed, the downward recess 37 of the lower frame 11 of the sash frame A is inserted into the vertical piece 4 of the lower fastener 38.

0 does not move in the out-of-plane direction, but is relatively movable in the in-plane direction and the vertical direction.

By doing so, the vertical frame 12 can move in the in-plane direction with respect to the vertical building frame 52, and the vertical frame 12 does not bend and deform due to the force in the out-of-plane direction. When the upper frame was fixed with an anchor so that it would not move in the in-plane direction and the lower frame was fixed with an anchor so that it did not move in the in-plane direction, the upper building frame and the lower building frame were displaced between layers. At this time, the vertical frame 12 moves in the longitudinal direction relative to the vertical building frame to prevent deformation of the sash frame, and the wind pressure resistance of the vertical frame 12 can be improved.

[0027]

Also,
Since the upper frame and the anchor do not move in the out-of-plane direction, the upper frame does not move due to the out-of-plane force due to strong wind and rain.

According to the second aspect of the invention, since the upper frame and the upper fastener and the lower frame and the lower fastener can be moved relative to each other in the in-plane direction, when the upper building body and the lower building body are displaced between layers, the interlayer displacement is caused. Can be absorbed to prevent deformation of the sash frame. Further, the upper frame and the upper fastener, the lower frame and the lower fastener can be respectively swung in the out-of-plane direction, and between the upper frame and the inner surface of the upper building body, and between the lower frame and the inner surface of the lower building body. Since there are respective gaps, it is possible to prevent the sash frame from being deformed by absorbing the movement of the upper building body and the lower building body when they relatively move in the out-of-plane direction.
