Description

[Detailed explanation of the invention] A. Purpose of the invention (industrial application field) This invention is an aluminum sash with an external frame that is attached to the window opening of a building with a structure in which panels are attached to a steel frame (hereinafter referred to as a steel frame panel structure). Regarding.

(Conventional technology) In order to install aluminum sashes to window openings in buildings with steel frame panel structures, conventionally, aluminum sashes were attached to the steel frame exposed at the edge of the window opening (a lightweight steel frame with a rectangular cross section and a cutout on one side was often used). , by welding a steel anchor and screwing the frame of the sash to the window opening, or by attaching wood 47 to the steel frame 1 as shown in the example of lower frame installation shown in Fig. 5. The lower frame 6 was placed on the liner 48 fixed to the frame and fixed with nails 49, and the outer frame 11 was fixed to the wood 47 with wood screws 50.

(Problems to be solved by the invention) With this type of sash mounting structure, not only is it cumbersome to connect the anchor and the sash frame with screws and attach the sash frame through wood, but it also requires drilling holes in the aluminum frame. The problem was that the anti-rust coating applied to the aluminum frame and outer frame to prevent rust was broken, and corrosion progressed from the holes.

B. Composition of the invention (Means for solving the problem) In this invention, the sash is placed on a lower anchor fixed to the steel frame to support its weight, and the sash is attached to the building integrally with the frame of the sash. The structure in which the frame of the sash is held down by the outer frame eliminates the need for mounting holes in areas where rainwater may enter, thereby solving the above-mentioned problems.

(Function) Since it is configured as above, most of the weight of the sash is supported by the lower anchor, and the movement of the sash inside and outside the building and in the left and right directions is suppressed by the outer frame, fixed pieces, and connecting pieces. The sash can be installed reliably, the installation work becomes simple, and the sash can be quickly installed.

(Example) Fig. 1 is a vertical cross-sectional view with the middle part omitted showing a structure in which the upper and lower frames of aluminum sash are attached to the window opening of a building with a steel frame panel structure, and Fig. 3 shows the vertical frame and the window opening. FIG.

At the bottom of the window opening, the steel frame 1 of the building has a box-shaped projecting piece 2 at the upper inner and outer ends (in this specification, the building side is called the inside, and the outside side of the building is called the outside).
Anchors 4 made of short aluminum extrusion with protruding lengths are fixed at several locations with bolts 5, and the lower frame 6 of the aluminum sash is placed on the outer protrusion 2, and the cross section is bent. The outer edge 7 of the lower frame 6 extending downward is fixed to the anchor 4 with rivets 8 or screws, and the inner edge 9 extending downward is fixed to the projecting piece 3 with screws 10. .

The lower outer frame 11 is attached to the anchor 4 by bolts 13 and nuts whose heads are unrotatably engaged in grooves 12 formed therein, and are pressed against the outer surface of the anchor 4 and the outer surface of the sash outer frame by tightening the nuts. A sealing material 14 interposed at the upper part prevents rainwater from entering between the outer picture frame and the outer frame of the sash. Even so, the small amount of rainwater that has entered flows through the grooves 15 formed in the outer frame, enters the box-shaped outer frame 11 through holes 16 drilled here and there, and enters the box-shaped outer frame 11 through holes drilled in the lower surface. Since it is discharged from 17, it does not enter the outer edge 7 of the lower frame.

A connecting piece 21 made of an extruded aluminum profile is assembled in advance to the upper frame 20 of the sash before installation.
A restraining arm 22 is formed at the outer end of the lower surface of the coupling piece 21, and elastically clamps the bent part 23 at the outer upper end of the upper frame together with the outer end of the coupling piece 21, and the inner end of the coupling piece 21 is a bent part 25 at the inner upper end of the upper frame with a screw 24.
is combined with

With the sash frame placed on the lower anchor 4 as described above, the connecting piece 21 is fixed by connecting the intermediate ridge 26 to the anchor 27 with the screw 28. As shown in FIG. 2, the anchor 27 has a portion of its inner and outer edges bent and bent, and the bent portion and the remaining unbent portion elastically clamp the opening edge of the steel frame 1. , with an L-shaped piece 29 welded to the bottom surface,
A plurality of them are provided scattered over the entire length of the upper frame 20.

The upper outer frame 30 is connected to the outer ridge 3 of the connecting piece 21.
1, it is attached with bolts 32 in the same way as the lower outer frame 11, and a sealing material 33 is pressed against the upper frame 20 to prevent rainwater from entering. In the upper part of the sash, there is little risk of rainwater entering between the sealing material 33 and the upper frame 21, so no drainage passage for intruding rainwater is provided.

Like the upper frame 20, the vertical frame 35 of the sash is supported on the steel frame 1 via the anchor 21 by a connecting piece 38 of an extruded aluminum member having ridges 36, 37. The connecting piece 38 holds the bent part of the outer end of the vertical frame with the elastic restraining arms 22, and the inner end is fixed by pulling the fixing piece 40 to the connecting piece 38 with the screw 39, so that the bent part of the inner end of the vertical frame is held. The bent portion 41 is held between the connecting piece 38 and the fixed piece 40. Fixed piece 4
0, as shown in FIG. 4, has one end bent to about the thickness of the bent portion 41 and a female threaded hole into which the screw 39 is screwed.

The vertical outer frame 42 has grooves 4 like other outer frames.
The vertical frame 35 is connected to the vertical frame 35 and the connecting piece 38 by a bolt 44 and a nut whose heads are connected to the sealing material 45.
This prevents rainwater from entering. Even if a small amount of rainwater invades the sealing material 45, this rainwater flows down and is discharged from the space 46 formed by the coupling piece 38 and the vertical outer frame 42.

C. Effect of the invention Since the frame of the aluminum sash is attached to the window opening of the building as described above, there is no need to drill holes in the frame for attachment in places where corrosion is likely to occur when wet with rainwater, and the frame is coated with anti-corrosion coating. The effect can be maintained for a long time, and there are fewer parts to be screwed together at the construction site, making installation work easier. A sash that connects the upper frame to the steel frame and attaches the outer frame to the upper frame is described in Japanese Utility Model Application Publication No. 183139/1983, but this one uses separate metal fittings to attach to the steel frame and to attach the outer frame. Therefore, the number of metal fittings used increases. Since the present invention performs the above two attachments using only one metal fitting, the preparation, management and use of the metal fitting are much easier.
