Description

[Detailed description of the invention] This invention relates to a window frame structure that constitutes a double window by attaching a new window frame to an existing window frame, and particularly relates to a structure for attaching a new window frame to the top of the new window frame. .

In the past, various proposals have been made to create double-glazed windows by installing a new window frame on the indoor or outdoor side of the existing window frame in addition to the existing window frame. There are other problems, such as the need to repair the exterior wall and the large number of man-hours required for installation.Furthermore, if the thickness of the exterior wall differs, it takes time and effort to install the upper window frame in the new window frame.

This idea was devised in view of the above circumstances, and its purpose is to install a new window frame in the existing state without modifying the exterior wall, regardless of the shape or thickness of the exterior wall of the existing window frame. To provide a window frame structure of a double-glazed window that can be easily installed and has good rain protection.

This invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a longitudinal section showing the window frame structure of a double-glazed window according to this invention.

A in the figure indicates the existing window frame.

The existing window frame A has been installed in advance over the lintel B1 and window sill B2 at the opening of the building frame B.

Incidentally, an attachment aid 3 is attached to the outdoor side flange 2 of the upper frame 1 of the existing window frame A.

Here, the mounting auxiliary material 3 consists of a base piece 4 attached and fixed to the outdoor side flange 2 of the upper frame 1 of the existing window frame A, and a mounting piece 5 extending from the base piece 4 to the outdoor side. .

In addition, C in the drawing indicates a newly installed window frame.

The new window frame C is located on the outdoor side of the existing window frame A, which has been previously installed in the building frame B, and is attached to the existing window frame A.

To explain this juxtaposed state in detail, first, the upper frame 6 of the newly installed window frame C has a connecting piece 7 projecting from the upper frame 6 body to the indoor side.

The connecting piece 7 and the attachment piece 5 of the attachment aid 3 attached to the existing window frame A overlap each other.

A sealing material 8, which also serves as a heat insulating material, is interposed in the molded portion, and both pieces 7.5 are connected by screw members 9 or the like.

By the way, for the new window frame C, the upper frame 6 of the new window frame C is positioned below the end face of the existing exterior wall, and the existing window frame C is placed between the end face of the existing exterior wall and the upper surface of the upper frame 6 of the new window frame C. A gap S is provided between the connected portion of the upper frame 1 of A and the upper frame 6 of the newly installed window frame C so as to communicate with each other, and the gap S is filled with joint material 10 for installation.

The above is the configuration showing the state in which the upper frame 6 is installed in the newly installed window frame C.

According to this configuration, the upper frame 6 of the newly installed window frame C can be installed concurrently without modifying the existing exterior wall.

Further, even if the eaves 11 are provided protruding from the side surface of the existing exterior wall outside the room, a new window frame C can be installed without damaging the eaves 11.

Note that FIGS. 3 and 4 are longitudinal cross-sectional views showing other embodiments of the mounting structure for the newly installed window frame C according to this invention.

In the embodiment shown in FIG. 3, the base piece 4 of the mounting aid 3 is attached and fixed to the outdoor side flange 2 of the existing window frame A, and the mounting piece 5 of the mounting aid 3 is made to protrude to the outdoor side. The mounting piece 5 is connected to the connecting piece 7 of the newly installed window frame C and the upper sill 6 with a sealing material 8 interposed therebetween.

Then, a gap S is provided between the outdoor side surface of the existing exterior wall and the upper surface of the upper frame 6 of the new window frame C, and a joint material 1 is applied to the gap S.
0 is filled with the upper frame 6 of the newly installed window frame C.

Next, to explain the embodiment shown in FIG. 4, the upper frame 6 of the new window frame C is directly screwed to the outdoor side flange 2 of the upper frame 1 of the existing window frame A with a sealing material 8 interposed. .

Then, position the upper edge 6 of the new window frame C below the end face of the existing exterior wall, and connect the end face of the existing exterior wall with the new window frame C.
A gap S is provided between the upper surface of the upper frame 6 and the gap S is filled with a joint material 10, and the newly installed window frame C is attached.

In addition, in each of the embodiments shown in FIGS. 3 and 4 described above, the gap S is provided to communicate with the connected portion of the upper frame 1 of the existing window frame A and the upper frame 6 of the new window frame There is.

. Furthermore, regarding the installation of the lower frame 6a of the new window frame C, as shown in FIG. and the lower frame 6a of the newly installed window frame C may be connected with the sealing material 8 interposed.

Furthermore, the installation of the short frame 12 of the newly installed window frame C is shown in FIG.

That is, the mounting aid 3b is fixed in advance to the short frame 13 of the existing window frame A, and the mounting aid 3b and the short frame 12 of the new window frame C are connected via the sealing material 8.

Next, the gap S between the outdoor side surface of the short frame 12 of the new window frame C and the existing exterior wall is filled with joint material 10, and the short frame 12 of the new window frame C is attached.

Thus, the window frame structure of the double-glazed window in this invention is constructed as described above.

The window frame structure of a double-glazed window according to this invention, particularly the newly installed window frame top mounting structure, has the following advantages.

■ The newly installed window frame is the exterior wall of the existing window frame...
It can be attached to any shape or thickness without any modification.

■ The new window frame upper frame is attached directly or indirectly to the outdoor flange of the existing window frame upper frame, and a gap is provided between the existing exterior wall and the new window frame upper frame. The upper part of the new window frame can be attached simply by filling the joint with joint material, making the installation process extremely easy.

■ Since the structure is such that a joint material is filled between the end face of the exterior wall and the top surface of the new window frame, there is no risk of rainwater, etc. dripping down the exterior wall surface entering the window frame.

■ Also, since the gap filled with joint material is provided to communicate with the connection between the upper edge of the existing window frame and the upper edge of the new window frame, there is a risk of rainwater leaking from the connection between the upper frames. do not have.

-Furthermore, even if an eaves protrudes from an existing exterior wall, a new window frame can be easily installed without the eaves getting in the way.

Therefore, the practical value of this idea is extremely high.
