Description

[Detailed explanation of the invention] This invention leaves the sash frame installed in the opening of the building as it is without removing it.
This invention relates to a renovated sash which is installed by covering the existing sash frame with a cover piece formed by extending the new sash frame toward the indoor side.

In recent years, aluminum sashes have become extremely widespread and can now be installed in most openings in buildings, whether they are houses or buildings.

However, even with aluminum sashes, which generally have excellent corrosion resistance (in addition, iron sashes were temporarily used), they are often exposed to salt air, acid rain, etc., so they cannot be used for many years. As a result, it is inevitable that staining and corrosion will progress, and that the tight material will deteriorate and wear out, resulting in a decline in airtightness and watertightness. Therefore, there is a demand for replacing these old sashes with newer and better performance sashes.

In response to such requests, if you are attempting to remove the existing sash and install a new sash,
In conjunction with the removal of the existing sash, the interior and exterior of the building must also be updated or reworked, which poses problems in that it requires complicated work, takes many days for construction, and increases costs.

Therefore, in order to solve such problems,
Leave the existing sash frame as it is without removing it, and cover and secure the new sash frame's extended indoor side cover piece over the prospective surface of the existing sash frame.
A refurbished sash has also been developed that improves the airtightness and watertightness of the sash by sealing between the outer periphery of the new sash frame and the building opening.

However, in the case of such conventional refurbished sashes, when a large difference occurs between the outdoor atmospheric pressure Po and the indoor atmospheric pressure Pi bordering on the seal, such as during a rainstorm, the pressure difference As a result, air from outside the room flows into the room between the sealing materials, and rainwater enters the room along with this air.

This idea was developed by focusing on the problems of the conventional sash frames mentioned above.In a renovated sash frame in which a new sash frame is installed on top of an existing sash frame, pressure between the outdoor side and the indoor side can be reduced even during rainstorms. To provide a renovated sash that can prevent rainwater, etc. from entering the indoor side through a sealing part even when the difference becomes large.

That is, in this invention, a cover piece extending toward the indoor side of a new sash frame is placed and fixed on the prospective surface of the existing sash frame, and a cover piece extending toward the indoor side of the new sash frame is placed between the existing sash frame and the indoor side cover piece of the new sash frame. The formed vertical and horizontal spaces are communicated with each other, and the outdoor side of the upper space of the space is sealed, and the space is connected to the atmosphere through the opening formed in the outer peripheral part of the new sash frame. It is characterized by being connected.

Even in this case, the risk of rainwater infiltrating into the indoor side can be extremely reduced, and the new sash lower frame 60 can be well supported on the draining piece 27 via the extension piece 69. become.

As explained above, in the remodeling sash according to this invention, a cover piece extending toward the indoor side of the new sash frame is placed and fixed on the prospective surface of the existing sash frame, and the existing sash frame and the new sash frame are fixed together. The vertical and horizontal spaces formed between the indoor side cover piece and the indoor side cover piece are communicated with each other to seal the outdoor side of the upper space of the space, and the opening formed on the outer periphery of the new sash frame is sealed. Since the space is communicated with the atmosphere through the structure, even when the pressure difference between the outdoor side and the indoor side becomes large during a rainstorm, etc., the indoor side of the existing sash frame and the new sash frame can be connected to each other. Since the above-mentioned space formed by the extended cover piece is always at the same pressure as the outdoor side, the pressure on the indoor and outdoor surfaces of the caulking material that isolates the upper space from the outdoor side is equal, and therefore the pressure of the caulking material is Since there is no air flow between the spaces, it is possible to prevent rainwater from entering the space, and even if rainwater does enter the space, there will be no major damage to the space. Since the pressure is equal to the atmospheric pressure, rainwater does not accumulate in the space, and once it falls into the lower frame of the existing sash, it quickly flows out from the lower opening, improving the watertight performance of the renovated sash. It has the very excellent effect of significantly improving the
