Description

[Detailed Description of the Invention] The present invention relates to a simple retrofitted heat insulation and soundproof sash.

BACKGROUND ART In recent years, due to the trend towards energy conservation and the increase in urban noise, there has been a demand for heat insulation and soundproof properties for windows of buildings. Therefore, it is necessary to replace old sashes or sashes with insufficient performance with high-performance sashes. However, replacement work was difficult and expensive.

In view of the above points, it is an object of the present invention to provide a simple post-installation heat insulation and sound insulation sash that is inexpensive, can be easily installed, and can provide sufficient heat insulation and sound insulation effects.

The structure of the present invention will be explained in detail based on the embodiment shown in the drawings.It is composed of an upper frame 1, a lower frame 2, and both rigid frames 3 and 4.

As shown in FIG. 1, the upper frame 1 has an airtight material attachment part 6 in the form of a groove with a lip that protrudes vertically on the outdoor end of the top plate 5, an inner wall 7 that protrudes from the lower surface on the indoor side, and a central part. Two guide protrusions 8, 8' are provided on the lower surface.

As shown in FIG. 1, the lower frame 2 is provided with an airtight material attachment part 10 in the form of a groove with a lip on the lower surface of the outdoor end of the bottom plate 9, an inner wall vertical piece 11 extending vertically at the indoor end, and Two rails 12, 12' are provided, and a locking piece 13 with an open outdoor side is protruded from the lower surface of the rail 12' on the outdoor side.

As shown in FIG. 2, both rigid frames 3 and 4 are provided with an airtight material attachment part 15 in the form of a groove with a lip at the center of the outdoor end of the side plate 14, and an inner wall 16 extending toward the center at the indoor end.
has been established.

A retrofitted window frame A is constructed by connecting the upper and lower frames 1 and 2 and both rigid frames 3 and 4 configured as described above, respectively.

On the other hand, the existing window frame B is constructed as shown by the chain line in FIGS. 1 and 2, and a frame C is provided on the circumferential surface on the indoor side.

The retrofitted window frame A is inserted into the picture frame C, and one continuous airtight material 17 or separate airtight material 17, etc. is fitted to each of the airtight material mounting portions 6, 10, 15, 15, respectively. This airtight material 17 is brought into close contact with the interior wall D of the existing window frame B, and is fixed to the picture frame C via a frame attachment fitting 18 and a lower frame attachment fitting 19.

The frame mounting bracket 18 is constructed as shown in FIG. At one end of the frame mounting piece 20, a part is bent at a right angle in the width direction to form a connecting piece 21, and the other part is bent further toward the indoor side than this connecting piece 21 in the width direction and then bent at right angles in the same direction. A picture frame mounting member 23 is bent to provide a finished picture frame mounting piece 22, and one end of the frame mounting piece 24 is bent at right angles to form a connecting piece 25, and a long hole 26 is provided in the longitudinal direction of this connecting piece 25. and a frame mounting member 27.

The lower frame mounting bracket 19 is constructed as shown in FIG. That is, a vertical piece 29 extending upward is provided on the outdoor side of the frame mounting piece 28, a locking piece 30 parallel to the frame mounting piece 28 is provided on the upper end of the vertical piece 29 on the indoor side, and a locking piece 30 is provided on the indoor side of the frame mounting piece 28. A continuous piece 31 is provided by bending a part upward in the width direction, and the other part is bent downward after extending further toward the indoor side than the continuous piece 31 in the width direction to form a finished frame mounting piece 32. are doing.

When installing the retrofitted window frame A, attach the frame mounting member 23 of the frame mounting bracket 18 to several predetermined locations on the top and side surfaces of the frame C so that the connecting piece 21 is located on the indoor side of the frame C. Attach the picture frame mounting piece 20 to the picture frame C.
Fasten with screws (not shown) along the On the other hand, attach the frame mounting members 27 to the positions facing the frame mounting members 23 of the upper frame 1 and both rigid frames 3 and 4 so that the connecting pieces 25 face the frame C side.
3. Fix with...

On the other hand, the lower frame mounting bracket 18 has a vertical piece 2 attached to the frame C.
Fasten the frame mounting pieces 28 with screws (not shown) at several locations so that 9 faces upward.

Then, insert the retrofitted window frame A into the space of the picture frame C,
When the locking piece 13 of the lower frame 2 is engaged with the locking piece 30 of the lower frame mounting bracket 19, the connecting piece 31 is connected to the inner wall vertical piece 1.
It will be located on the outdoor side of 1, and the vertical piece of the inner wall 1
It is connected to the connecting piece 31 through screws 34, . . . from the first side. In the upper frame 1 and both rigid frames 3 and 4, the connection piece 25 of the frame attachment member 27 is connected to the connection piece 2 of the frame attachment member 23, respectively.
The connecting pieces 21 and 25 are fixed to each other by passing screws 35, . This completes the attachment of the retrofitted window frame A to the picture frame C.

Incidentally, during installation, the sash of the present invention may be fitted and fixed at the end.

After that, attach each U-shaped finished picture frame E, ... to the finished picture frame mounting pieces 22, ... and 32 with screws 3.
6. Fix it through... At this time, finish the frame E
The inner circumferential wall F is the inner wall 7, 16 and the inner wall vertical piece 1, respectively.
1, and the outer peripheral wall G is packed against the wall H.
Abutted through.

In addition, J in Figure 1 is the curtain rail, and the fixture K is
It is fixed to the finished picture frame E of the upper frame 1 via.

The present invention is constructed as described above, and is designed to be attached to an existing picture frame C via the mounting bracket, so there is no need to perform the removal process as in the past, and it can be easily attached. This creates a double-glazed window, which provides sufficient heat insulation and soundproofing effects. In addition, the frame mounting bracket 18 has a long hole 26 on the frame mounting piece 24 side that is fixed to the rear window frame A, and a long hole 26 on the frame mounting piece 20 that is fixed on the frame C side.
Since the connection is made with screws through 6, even if there is a dimensional error between the retrofitted window frame A and the picture frame C, the position can be adjusted using the elongated hole 26 to securely connect the connecting piece 25 to the connecting piece 21. can do.
