Description

[Detailed Description of the Invention] The present invention relates to a new aluminum window frame mounting device that uses the frame main body of an old window frame, such as an old steel plate or other iron window frame, as a mounting base.

Steel plate window frames used in buildings constructed a long time ago are severely stained and deteriorated due to rust or corrosion due to air pollution, etc., and their soundproofing effects against noise pollution are also poor. Renovation work will be completed to replace the steel plate window frames with new aluminum window frames that have excellent corrosion resistance and soundproofing properties.

In order to make the replacement work easier, faster, and cheaper, the present invention replaces the old steel plate window frames without having to remove the old steel plate window frames by removing the concrete walls. Peel off the window frame, leaving the base part intact.
The plan is to use this as a mounting base for a newly installed aluminum window frame.

The present invention makes it possible to perform the installation work extremely easily and quickly when attaching the frame main body of a new window frame to the mounting base using the above-mentioned construction method, and it also has a simple structure, is easy to manufacture, and can be installed robustly. The present invention provides a mounting device for obtaining the desired results.

Below, one embodiment of the present invention will be explained based on the drawings. In the drawing, 1 shows the main frame of an old window frame such as an old steel plate window outer frame attached to a building base 2 such as a concrete wall. In this process, the old frame main body 1 is left as a mounting base by appropriately cutting off unnecessary projecting parts and the like.

3 shows the frame body of an aluminum window frame to be newly installed, and the frame body 3 to be cut has a hook-shaped protrusion 3as on a part of its anchor.
3b are provided to extend opposite each other, and an auxiliary anchor for the anchor may be attached thereto as required, although not shown.

There is a subsidy item 4 between the old frame subject 1 and the new frame subject 2.
is interposed, its flat surface 5 is fixed to the old frame main body 1 by welding 6 or screws 7, and an L-shaped bent end 8 is bent inward on the indoor side of the new frame main body 30. The L-shaped bent end 8 is brought into contact with the indoor end surface 9 and is secured by a screw 10.
is fixed to the end surface 9, and a part of the auxiliary fitting 4, which is located further toward the indoor side than the bent end 8, is bent parallel to the bent end 8 to attach the picture frame. A frame mounting bracket 12 is fixed to the bent end 11 by welding or screws 13, and the indoor side edge 14 is attached to the mounting bracket 12 by screws 15. is fixed by

Note that even if the auxiliary hardware 40 is located on the outdoor side, an L-shaped bent end 16 is bent inward, and an outdoor frame mounting bracket 17 is fixed to this with screws 18, and the outdoor frame 19 is attached to the mounting bracket 17. is engaged.

In the figure, 20 and 21 are caulking materials, and 22 is the interior frame of the new window frame.

When interposing the auxiliary hardware 4 between the frame upper body 1 of the old window frame and the frame upper body 3 of the new window frame to fix both, the auxiliary hardware 4
A steel plate piece is used for its strength, whereas the new frame upper body 3 is made of aluminum, so when fixing the new frame upper body 3 to the auxiliary fitting 4, screw fastening means is often used instead of welding. Ru.

Then, as in the present invention, an L-shaped bent end portion 8 formed by bending the interior side of the auxiliary hardware 40 fixed to the old frame upper body 1 inward.
When fixing the new frame upper body 3 to the old frame upper body 1 by fixing the screw 10 to the indoor side end face 9 of the new frame body 30, the screw head 10' protrudes from the indoor side end face 9 of the new frame body 30. As a result, either the frame mounting bracket 12 could not be mounted on the same end face due to this problem, or the frame mounting bracket 12 had to be mounted in an unstable state by contacting the screw head 10'.

J On the other hand, in the present invention, the frame-mounting bracket fixing bent end 11 is formed in parallel with the frame upper body screw-fastening bent end 8 in such a state that it protrudes further toward the indoor side. In order to
A screw head 10 is fixed to the L-shaped bent end 8 of the latter.
', the frame mounting bracket 12 can be stably mounted on the indoor end surface 9, and since it is integrally formed with the auxiliary hardware 4, it has sufficient strength.
