DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a sash frame on a building frame so that the sash frame can be displaced between layers.

[0002]

2. Description of the Related Art As a structure for attaching a sash frame to a building frame, for example, as shown in Japanese Utility Model Laid-Open Publication No. 63-12584, a sash frame is mounted on four sides of an opening of a building frame made of concrete via an anchor. It has been known.

With this mounting structure, since the vertical frame constituting the sash frame is supported by the building frame with the anchor, it does not bend in the longitudinal direction due to wind pressure. When the lower building frame to which the frame and the lower part of the sash frame are attached is displaced between layers due to an earthquake or the like, the interlayer displacement cannot be absorbed.

For this reason, in order to attach a sash frame to a building frame in which the upper building frame and the lower building frame are displaced between layers, the above-described interlayer displacement is absorbed without connecting the left and right vertical frames forming the sash frame to the building frame. I can do it.

[0005]

However, as described above, if the left and right vertical frames are not connected to the building frame, the vertical frames may be bent and deformed in the longitudinal direction due to wind pressure. And has a large rigidity so as not to bend in the longitudinal direction by wind pressure.

If a vertical frame having a hollow portion is used, the weight of the entire vertical frame is increased, the amount of necessary materials such as aluminum is increased, and processing and mounting of the hollow portion are troublesome, resulting in cost. Becomes a high vertical frame.

[0007] The vertical frame of the sash frame is extruded from an aluminum material and is formed by extrusion. However, if the vertical frame has a hollow portion as described above, the shape of the mold becomes complicated, and the molding cost is high.

Accordingly, an object of the present invention is to provide a sash frame mounting structure capable of solving the above-mentioned problems.

[0009]

According to a first aspect of the present invention, there is provided a sash frame mounting opening composed of a lower building frame, an upper building frame, and right and left wall members mounted over the lower building frame and the upper building frame. In the structure in which the sash frame is mounted, the vertical frame constituting the sash frame has a plate-shaped body integrally provided with an indoor-side outward piece and an outdoor-side outward piece, and a hollow portion is formed at a longitudinally intermediate portion of the vertical frame. A short supporting metal member having a longitudinally movable end which is in contact with the indoor outward piece and the outdoor outward piece and does not move in the out-of-plane direction so as to be movable in the longitudinal direction. This is the mounting structure of the sash frame connected to the material. A second invention provides a structure in which a sash frame is attached to a sash frame mounting opening formed of a lower building frame, an upper building frame, and left and right wall materials mounted over the lower building frame and the upper building frame. The vertical frame that makes up the frame,
Shall have to face the outdoor recess toward the interior side recesses and the indoor side toward the exterior side in the plane direction near both ends in the outer surface of the plate-like body, the middle in the longitudinal direction intermediate portion of the vertical frame
A short supporting bracket having a vacant portion is supported by fitting both ends in the out-of-plane direction to the indoor-side concave portion and the outdoor-side concave portion so as to be movable in the longitudinal direction, and the supporting metal member is connected to the wall material. This is the mounting structure of the sash frame.

[0010]

According to the first aspect of the present invention, the vertical frame forming the sash frame can move in the longitudinal direction with respect to the support bracket, so that the vertical frame and the wall material are displaced when the lower building frame and the upper building frame are displaced between layers. It relatively moves in the longitudinal direction and absorbs interlayer displacement. In addition, the middle part in the longitudinal direction of the vertical frame has a hollow part with a hollow part.
The vertical frame of insufficient rigidity consisting of the plate-shaped main body, the indoor-side outward piece, and the outdoor-side outward piece is bent in the longitudinal direction by wind pressure due to being supported in the out-of-plane direction by the wall material through the support metal of the shaku. There is no. According to the second invention, the vertical frame constituting the sash frame can move in the longitudinal direction with respect to the support bracket, so that when the lower building frame and the upper building frame are interlayer-displaced, the vertical frame and the wall material are opposed to each other in the longitudinal direction. Move to absorb interlayer displacement. The middle part of the vertical frame in the longitudinal direction is a hollow part.
Since the vertical frame is supported in the out-of-plane direction by the wall material via the short supporting metal having the plate and the vertical frame is prevented from being displaced in the in-plane direction with respect to the supporting metal, the plate-shaped main body and the indoor side are prevented. The vertical frame having insufficient rigidity formed by the concave portion and the outdoor concave portion is not bent and deformed in the longitudinal direction by wind pressure, and the support bracket is provided.
High rigidity ensures that the vertical frame is twisted and deformed
Can be prevented.

A wall material 2 below a PC board, an ALC board, etc. is attached to the lower building frame 3, and a PC board, AL
An upper wall member 5 such as a C-plate is attached to form an upper building frame 6, and the lower building frame 3 and the upper building frame 6 undergo interlayer displacement due to an earthquake or the like, and the lower wall member 2 and the upper wall member 5 A sash frame mounting opening 8 is formed by the left and right middle wall materials 7 and the upper and lower wall materials 5.2, and a sash frame mounting opening 8 is formed. A sash frame A is attached to the opening 8.

The sash frame A is formed into a rectangular frame by an upper frame 10, a lower frame 11, and left and right vertical frames 12. The upper frame 10 is connected to an upper wall member 5 by an anchor 13, and the lower frame 11 is connected to a lower wall. The wall member 7 is connected to the member 2 by an anchor 14, and the intermediate wall member 7 is also connected to the upper wall plate 5 and the lower wall plate 2 by a connection fitting 15, respectively.

Thus, when the lower building frame 3 is displaced between layers in the direction of arrow a and the upper building frame 6 in the direction of arrow b, the sash frame A is deformed as shown in FIG. As shown in FIG. 2, the sash frame A is in an oblique posture and absorbs interlayer displacement, so that the vertical frame 12 of the sash frame A and the intermediate wall member 7 are relatively displaced in the longitudinal direction.

For this reason, if the vertical frame 12 and the intermediate wall member 7 are connected to each other by an anchor or the like, they cannot be relatively displaced in the longitudinal direction. Therefore, conventionally, the vertical frame 12 is not connected to the intermediate wall member 7 by the anchor or the like. In addition, since the vertical frame 12 is formed to have a hollow portion so as not to be bent and deformed in the longitudinal direction by wind pressure, the above-described problem occurs.

As shown in FIG. 3, the vertical frame 12 is provided with an indoor outward piece 21 and an outdoor outward piece 22 integrally provided on the outer surface of a plate-shaped main body 20 facing outward, and has a substantially cross-sectionally outward facing direction. It has a U-shape, and the indoor-side outward piece 21 is integrally provided with an indoor-side support piece 23 facing the outdoor side, and forms an indoor-side concave portion 24 facing the outdoor side with the plate-shaped main body 20.

The projecting end of the outdoor outward piece 22 is bent into a hook shape to form a seal receiving piece 25, and a sealing material 26 is mounted between the outdoor wall 22 and the intermediate wall member 7. The outdoor piece 22 is provided integrally with an outdoor support piece 27 facing the indoor side to form an outdoor recess 28 facing the indoor between the plate-shaped main body 20. The indoor-side concave portions 24 face each other, and a support fitting 30 is supported between the two.

As shown in FIGS. 3 and 4, the supporting bracket 30 is a short member having a hollow section 33 formed by a plate 31 and a U-shaped member 32. The dimension of the plate 31 in the out-of-plane direction is the same as that of the chamber. The inner surface of the inner outward piece 21 (the indoor recess 2)
4 and the inner surface of the outdoor outward piece 22 (the bottom surface of the outdoor concave portion 28).
Is formed by bending a plate material in a cross-sectional shape in which bent pieces 35 are integrally provided on both sides of the U-shaped piece 34, and the U-shaped material 32 has the same out-of-plane dimension as the plate 31,
The bent piece 35 is fixed to the plate 31 by welding or the like to form a hollow portion 33 between the U-shaped piece 34 and the plate 31, and the plate 31 and the bent piece 35 form a support portion 36.

The thickness of the supporting portion 36 is the same as that of the recess 24 on the indoor side.
The width of the opening is substantially the same as (slightly smaller than) the opening width of the outdoor concave portion 28, and the support portion 36 is attached to the indoor concave portion 24 and the outdoor concave portion
The supporting bracket 30 is supported at the intermediate portion in the longitudinal direction of the vertical frame 12 by fitting into the vertical frame 12. The vertical frame 12 and the supporting bracket 30 cannot be displaced in the out-of-plane direction but can be displaced in the longitudinal direction.

A pair of reinforcing bars 41 are fixed to the intermediate wall member 7 via an L-shaped member 40 so as to be vertically separated from each other.
1 is fixed to the upper and lower portions of the U-shaped piece 34 of the support bracket 30 by welding or the like, and the mounting bracket 30 is connected to the intermediate wall member 7.

Before the sash frame A is mounted, the support bracket 30 may slide down on the vertical frame 12 and drop. Therefore, the screw 37 is folded from the indoor outward piece 21 to the indoor support piece 23. The support fitting 30 is temporarily supported so as not to be screwed into the bent piece 35 and dropped, and the screw 37 is removed when the support fitting 30 is fixed to the reinforcing bar 41.

As described above, the vertical frame 12 can be relatively moved in the longitudinal direction with respect to the intermediate wall member 7, and the intermediate portion in the longitudinal direction is supported by the support bracket 30 so as not to move in the out-of-plane direction. In addition, the interlayer displacement between the lower building frame 3 and the upper building frame 6 can be absorbed, and the vertical frame 12 does not bend in the longitudinal direction due to wind pressure.

Further, since the support portions 36 on both sides of the support fitting 30 are fitted into the indoor recess 24 and the outdoor recess 28 of the vertical frame 12, it is possible to prevent the vertical frame 12 from being twisted.
0 can prevent it. In particular, since the support fitting 30 has a rigid shape having the hollow portion 33, the torsion deformation can be reliably prevented.

A sliding member having a small sliding resistance is provided between the support portion 36 of the support fitting 30 and the indoor recess 24 and the outdoor recess 28 so that the vertical frame 12 moves smoothly in the longitudinal direction. Is also good.
