Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of renovating an old existing frame for a building opening such as a window with a new frame made of aluminum.

When renovating old existing frames used for openings such as windows in existing buildings, new frames are fixed with the existing frames remaining in order to reduce work noise and reduce renovation costs. It is desirable to
Various proposals have already been made regarding specific methods for this purpose.

However, these methods do not give special consideration to simplifying the on-site work as much as possible and thereby shortening the on-site construction period. In particular, when the work site is a residence where people live, a hospital where patients are hospitalized, or a business building where business is performed, it is required to shorten the work time at the site.

The present invention provides a method for renovating a building opening that satisfies such requirements. In particular, a rectangular mounting frame is integrally fixed in advance around a new aluminum frame, and the mounting frame is attached to the building opening. The new frame can be installed in a short time by an extremely simple method of fixing it to anchor bolts driven into the outer wall surface around the four sides of the frame.

Hereinafter, a case in which the method of the present invention is applied to window frame renovation will be specifically described with reference to the drawings. Figures 1 to 3 show the configuration of a building opening that has been renovated using the method of the present invention. In this renovation, the old existing frame 1 is left without being removed, and aluminum Install new frame 2.
Leaving the existing frame 1 in place is effective in suppressing the work noise that accompanies its removal work, and is also effective in reducing construction costs because it shortens the construction period and simplifies the renovation work. Note that protruding or corroded parts of the existing frame, members that can be easily removed with screws, etc. may be removed.

The new frame 2 to be installed as a new window frame is assembled in advance at the factory or on site on the top, bottom, left and right sides, and the required spacing is placed between the top side 2a and left and right sides 2b, 2b as shown in Figures 1 and 3. The anchor 3 is attached, and iron reinforcing members 4a to 4c are fixed around it. These iron reinforcing materials 4a to 4c supplement the strength of the new frame 2 made of aluminum, and
This is to allow a mounting frame 6, which will be described later, to be easily fixed around the new frame 2.It is formed into a frame shape by attaching it to the top, bottom, left and right sides of the new frame 2, and the lower surface of the reinforcing material 4c at the lower side 2c is A mounting base 5 made of angle material is fixed. The reinforcing material is fixed to the new frame 2 by welding the reinforcing material 4a, 4b, 4b to the anchor 3 on the upper side 2a and the left and right sides 2b, 2b by spot welding from the outside, and on the lower side 2b, 2b.
Step c is performed by fixing the reinforcing member 4c and the new frame 2 with screws screwed into appropriate positions. Furthermore, a rectangular mounting frame 6 is fixed around the new frame 2 to which the reinforcing frames 4a to 4c and the mounting base 5 are attached in this manner. The mounting frame 6 is configured to have a larger diameter than the new frame 2 by arranging angle members vertically and horizontally and connecting them to each other. When the mounting frame 6 is fixed to the new frame 2, On the upper side 2a and the left and right sides 2b, reinforcing members 4a, 4b, 4
b and each side 6a, 6b of the mounting frame 6 facing this,
6b, a plurality of connecting fittings 7 are arranged at appropriate intervals, and on the lower side 2c, they are arranged in the same way as the connecting fittings 7 between the mounting base 5 and the lower side 6c of the mounting frame 6. Both ends of the connecting fitting 7 are connected to the reinforcing members 4a, 4b, 4b, the mounting base 5 and the mounting frame 6.
Each side is fixed by welding.

The new frame 2 to which such a mounting frame 6 has been fixed in advance in a factory or on-site is installed from the outside into a building opening. A plurality of anchor bolts 9 are driven at the same pitch as the plurality of mounting holes 8 provided in each of the holes 8 to 6c, and the anchor bolts 9 are inserted into the mounting holes 8 and the nuts 10 are screwed, thereby making the installation possible. The frame 6 is fixed to the anchor bolt 9.

After installing the new frame 2 in this way, screws
At the same time, an interior frame that covers the peripheral side of the building opening, that is, the existing frame 1, is attached to the inside of the new frame 2 with screws 13, and the renovation is completed by filling the required places with caulking material.

As is clear from the detailed description above, according to the method of the present invention, a mounting frame is fixed in advance around a new aluminum frame, and the mounting frame is fixed to anchor bolts driven into the wall surface. As a result, the work to install the new frame on site can be done in an extremely short time.

Claims (1)

[Claims] 1 The existing frame at the opening of the building will remain without being removed, anchor bolts will be driven into the outer wall surface around the opening, and the new aluminum frame to be fitted into the opening will be fitted with steel around it. In addition to fixing the reinforcing material, a rectangular mounting frame with a larger diameter than the new frame is fixed via connecting metal fittings interposed between the opposite sides of both frames, and this new frame is attached to the outside of the opening in the building. A method for renovating an opening in a building, characterized by fitting the surrounding mounting frame into the new frame, fixing the surrounding mounting frame to the anchor bolt, and appropriately connecting and fixing an exterior material covering the wall surface to the new frame.
