Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching a new aluminum window frame to an existing old steel window frame.

Conventionally, this type of installation method involves assembling the new window frame integrally with the upper and lower frames and the left and right vertical frames in advance, and then attaching it to the existing old window frame using auxiliary fittings (for example, Japanese Patent Publication No. 54-12749). (Japanese Patent Publication No. 53-1587) are known.

However, with this installation method, the new window frame is assembled in one piece, so it takes time to transport it to the site, and there is inevitably a gap between the new window frame and the old window frame. The new window frame was installed after removing the liner and other inclusions, which had the disadvantage of being cumbersome to install.

This invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to provide an installation method that does not require an intervening material such as a liner, is easy to install, and can firmly mount a new window frame. There is a particular thing.

The present invention will be described below based on illustrated embodiments.

In FIGS. 1 and 2, 2 is an old window frame that is integrally attached to the building frame 1, including an old upper frame 2A, an old lower frame 2B,
It consists of the old vertical frame 2C12D.

The new window frame 3 is the new upper frame 3A, the new lower frame 3B, and the new vertical frame 3C13.
These frames 3A and 3B consist of D.

The dimensions 3C and 3D are slightly smaller than the vertical and horizontal lengths of the opening of the old window frame 2, respectively.

To be more specific, the new vertical frames 3C and 3D have a thickness equal to the thickness of the receiving part protrusion (described later) of the caulking receiving material located between the end of the new vertical frame 3C and the inner peripheral surface of the old upper frame 2A and the old lower frame 2B. The tilled soil lower frames 3A and 3B are made smaller in size by the width of the caulking material filling which will be described later.

The new window frame 3 having such a configuration is directly attached to the old window frame 2 with screws, and there are two methods for this attachment: attaching the upper and lower frames first or attaching the vertical frame first.

When attaching the upper and lower frames first, as shown in FIGS. 3 to 8, the caulking receiver material 4 is attached to the end of the new lower frame 3B, and the caulking receiver material 5 is attached to the end of the tillage frame 3A.

The caulking receptacle material 4 of the new lower frame 3B consists of a base 4a, a caulking receptacle 4b, and a receptacle projecting piece 4c, as shown in FIGS. 3 to 5.

The upper surface of the base 4a is formed in a stepped shape corresponding to the inner surface at the end of the new lower frame 3B, and the base 4a is connected to the new lower frame 3B.
By inserting the caulking receiver into the end portion, the material 4 of the caulking receiver is fixed to the new lower frame 3B.

Note that there is a support piece 3B1 on the lower surface of the lower frame 3B and a mounting piece 3B2 on the interior surface, but the caulking receiver is notched in the part where the material 4 is located (not shown).

The upper surface of the caulking material receiving portion 4b is lowered one step lower than the upper surface of the base portion 4a, and is formed in a stepped shape similar to this upper surface.

The receiving portion protrusion 4c has a flat upper surface and is configured to extend and come into contact with the lower end surface of the new vertical frame 3C or 3D.

The caulking material 5 of the tillage frame 3A consists of a base portion 5a and a caulking material receiving portion 5b, as shown in FIGS. 6 to 8.

The base portion 5a is shaped to be inserted into the end of the tillage frame 3A, and the caulking material receiving portion 5b has a flat shape and is attached to the new vertical frame 3C.
Or it can extend upwards in 3D.

In a trap with such a configuration, a caulking receiver material 4 is attached to the end of the new lower frame 3B, and a caulking receiver material 5 is attached to the end of the tillage frame 3A. Attach directly to the paddy base frames 2A and 2B with screws.

Here, since the distance between the receiving part protrusion 4c and the coking material receiving part 5b is slightly larger than the length of the new vertical frame 3C or 3D, it is easy to insert the new vertical frame 3C, 3D into the old vertical frame 2C, 2D.
Can be installed on.

Next, by filling the caulking material receiving portions 4b and 5b with caulking material 6, the joint between the tilled soil lower frame and the new vertical can be protected from rain.

After the installation is completed, attach the decorative frame 7 on the indoor side as shown in Fig. 1, and then attach the new lower frame 3B on the outdoor side.
At the same time as fixing the water cutter 8 to the new window frame 3 on the outside of the room.
The outer periphery of the caulking material 9 is filled.

Next, if you are installing the vertical frame first, please refer to Figures 9 to 15.
As shown in the figure, caulking receiver material 10 is attached to the lower end of the new vertical frames 3C and 3D, and caulking receiver material 11 is attached to the upper end.

The caulking receiver 10 at the lower end consists of a base 10a and a receiver 10b, as shown in FIGS. 9 to 11.

The base 10a is formed into a step-like shape and is a new vertical frame 3C.

It is attached to the back surface of the base piece at the lower end of the 3D with screws 12.

The base 10& and the receiving part 10b are integrally formed. There are new vertical frames 3C, 3 between the base 10 and the receiving part 10b.
A groove 10c into which the lower end of the base piece D can be inserted is provided.

The upper surface of the receiving part 10b is formed in a stepped shape corresponding to the inner surface at the end of the new lower frame 3B, and is also formed so that it can extend at a predetermined distance from the inner surface at the end of the new lower frame 3B. .

Note that on the lower surface of the new lower frame 3B, there is a support piece 3B1 and a mounting piece 3B2 on the indoor side, but the caulking receiver is notched in the part where the material 4 is located (not shown).

The caulking receiving material 11 at the upper end consists of a base portion 11a and a receiving portion 11b, as shown in FIGS. 12 and 13.

The base portion 11a has a shape that is integrally bent from the receiving portion 11b, and is attached to the back surface of the base piece at the upper end of the new vertical frames 3C, 3D with screws 13.

The receiving portion 11b is a flat member that can extend at a predetermined distance from the inner surface of the end portion of the tillage frame 3A.

In such a configuration, caulking plates 10° and 11 are fixed to the upper and lower ends of the new vertical frames 3C and 3D, respectively, and the new vertical frames 3C are thus constructed.

Attach 3D directly to the old window frames 2C and 2D using screws.

In this state, as shown in Fig. 14, the tilled soil lower frame 3A
, 3B in the Kendon style and open the upper and lower mouth frames 2 A , 2
Fix directly to B with screws.

Here, as shown in FIG. 15, a new vertical frame 3C.

The inner peripheral protrusion 7272 piece at the lower end of 3D has a predetermined width of 11
Then, cut out the distance (caulking material width) 1 between the end face of the tilled soil lower frame 3A, 3B and the base piece of the tilled soil lower frame 3A, 3B.
2 must satisfy 72>-x.

In addition, a vertical piece on the outdoor side at the end of the new lower frame 3B is cut out to prevent this vertical piece from hitting the caulking member 10 during insertion.

In this way, the tilled soil lower frames 3A and 3B can be easily inserted in a sliding manner.

Next, by filling the receiving portions 10b and 11b with caulking material 6, the joint between the tilled soil lower frame and the new vertical can be protected from rain.

The subsequent steps are the same as those for attaching the tilled soil subframe in advance.

As described above, according to the present invention, the new vertical frame and the tilled soil lower frame are directly attached to the old window frame separately, thereby making the attachment work extremely easy and ensuring a strong attachment.

Furthermore, since the joint between the new vertical frame and the tilled soil lower frame is connected by the caulking material and the caulking catcher material, rain protection can be easily accomplished.

Furthermore, installation work is easy because no intervening material such as a liner is required.

Furthermore, there is an advantage that mutual displacement of the frames due to external force can be absorbed by the caulking material, and no displacement is transmitted to the narrow frame.
