Description

Detailed Description of the Invention (Field of Application and Object of the Invention) The present invention provides a method for repairing and repairing old window frames of buildings that have become obsolete due to long-term use, or for remodeling or improving insulation performance or functionality. This relates to window renovation methods that involve replacing old window frames with new window frames, and in particular applies to renovation methods that leave old window frames in place without removing them from the building frame and use them as mounting bases for new window frames.

(Prior art) Use old window frames as building walls and other structures! In recent years, many renovation methods have been proposed and are actually being implemented, in which a new window frame is placed over the window frame without removing the entire window frame. The advantage of this renovation method is that it eliminates the difficulty of removing the old window frame from the building frame and the need for a scaffolding frame for that purpose, but in the conventional construction method, the latter, in particular, is completely free of the scaffolding frame. It was especially difficult to do, and a lot of the work was done outdoors and near windows, which was quite dangerous. In addition, old window frames have unevenness and distortion on their surface due to long-term use.
It is extremely difficult to form a new window frame accurately. In this case, if there is a scaffolding frame, it can be installed with sufficient centering, but it is impossible to perform sufficient centering work under dangerous work without a scaffolding frame, so In the past, it was extremely difficult to accurately install new window frames adjacent to each other in alignment for each of the many old window frames installed in a building.

(Problems to be Solved by the Invention) Therefore, it is an object of the present invention to enable a new window frame to be accurately attached to an old window frame with less outdoor work and window work.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a structure! In a window renovation method in which a new window frame 3 is attached to an old window frame 2 that remains without being removed from the I body 1, a lower frame mounting hardware 4b is fixed to the lower frame 2b of the old window frame 2, and the lower frame is attached to the lower frame. The installation reference piece part 6.7 in the direction of the mounting hardware 4b.
On the other hand, of the new window frame 3 that was framed in a four-frame rectangular manner, mounting hardware for the upper frame and left and right vertical frames 4a, 4c, and 4d were fixed to the upper frame 3a excluding the lower frame 3b, and the left and right vertical frames 3c and 3d. This is made into an integrated object 5, and this is inserted into the older window frame 2 from the indoor side, and the lower frame 3b of the new window frame 3 is directly attached to the mounting reference pieces 6, 7 of the lower frame mounting hardware 4b, or the liner The mounting surface of the new window frame 3 is centered in the direction of the new window frame 3 by indirectly applying it through the adjusting tool 8, and then the mounting hardware 4a for the upper frame and the left and right vertical frames,
4c and 4d are the upper frame 2a and the left and right vertical frames 2 of the old window frame 2.
c, At the same time as fixing to 2d, lower frame 3b of new window frame 3
This method adopts a window renovation method in which the window is fixed to the lower frame mounting hardware 4b.

(Example) Unnecessary protruding parts of an old window frame 2 made of steel or aluminum attached to a building frame 1, which is a building wall, are removed as appropriate, and the rusted parts are coated with anti-rust paint. After that, a new window frame 3 made of aluminum or the like is attached to the old window frame 2 using the mounting hardware 4. First, attach the lower frame mounting hardware 4b to the lower frame 2b of the old window frame 2 using screws or anchor bolts (hole-in anchors). ) 15a. This mounting hardware 4b is mainly manufactured by bending steel or iron plates, and the vertical mounting reference piece 6 serves as the mounting reference for the new window frame 3 in the expected direction (indoor/outdoor direction) in the indoor I11. A horizontal mounting reference piece 7 is provided to serve as a mounting reference for the outdoor direction (1), and an outdoor vertical piece 10 is provided as appropriate for fixing the draining frame 9 and the new lower frame 3b with screws. As a whole, the cross section is formed into a substantially step-like shape.

On the other hand, as shown in Fig. 4, especially Fig. 5, the new window frame 3 is pre-assembled into a four-circumferential frame shape, and the upper frame 3a excluding the lower frame 3b, and the left and right vertical frames 3c and 3d have an upper frame and an upper frame. The mounting hardware 4a, 4c, and 4d for the left and right vertical frames are assembled as an integral part 5. That is, as shown in FIG. 1 or FIG. 5, the upper frame mounting hardware 4a has a disconnect circuit mainly consisting of a horizontal piece 11 to which the new upper frame 3a is attached and a vertical piece 12 to which the old upper frame 2a is attached. The horizontal piece 11 is provided with cut-and-raised pieces 13 as shown in FIG. Engagement piece 14.14
By hooking the screws 15b and 15C from the mounting hardware 48 side toward the upper frame 2a and holding it down,
The reaction force causes the upper frame upper edge 14.14 to be cut and raised and the piece 13
It is designed to strongly connect the two. In this way, attach the upper frame mounting hardware 4 to the new upper frame 3a.
a and, as shown in FIG. 3, mounting hardware 4c for the left and right vertical frames.

4d is also formed in a disconnected circuit shape, and its vertical frame mounting piece portion 16 is placed against the left and right vertical frames 3c and 3d, and this mounting piece portion 16 is placed against the engagement piece portions 17 and 17 of the vertical frames 3c and 3d. Fix the mounting hardware 4c, 4d to the new left and right vertical frames 3c, 3d by screwing in the screws 19 across the parts 18 and 18.

As described above, a new window frame 3 with mounting hardware 4a+4c, 4d attached to the upper frame and the left and right vertical frames is called an integrated unit 5, which is installed in the room as shown in FIGS. 4 and 5. Fit it into the window frame 3 that is older than the inside. At this time, since the lower frame mounting hardware 4b protrudes from the old lower frame 2b,
If this is an obstacle and it is difficult to fit, it can be easily fitted by tightening the upper frame toward the indoor side using a so-called flattening method.

After that, the integrated object 5 is placed vertically in the old window frame 2, and its lower frame 3b is directly applied to the forward direction mounting reference piece 6 of the lower frame mounting hardware 4b to perform centering in the forward direction. At the same time, the lower frame 3b and the direction mounting reference piece part 7
By interposing an adjusting tool 8 such as a liner with a height determined at the site between the two screws 20.2 and 20.2.
1, and then attach the upper frame mounting hardware 4.
An appropriate amount of liner 22 is also applied to the horizontal piece 11 of a.
The horizontal piece 11 is fixed to the old upper frame 2a with screws 23, and the vertical piece 12 is similarly fixed directly to the old upper frame 2a with screws 24. Also, as shown in Figure 3, the left and right vertical frame mounting hardware 4c and 4d are also screws 25.26.
It is fixed to the old vertical frames 2c and 2d. Finally, the outdoor picture frame 27 is secured with screws using the L fittings 28 (the fittings 28 are also screwed to the new upper frame 3a and left and right vertical frames 3c, 3d in advance (see Figure 5)), and the draining frame is attached. 9 and the new lower frame 3b are fixed to the outdoor vertical piece 10 of the lower frame mounting hardware 4b with screws 28, and the indoor frame 29 is fixed to the new upper, lower, left, right, and upper vertical frames 3a, 3b, 3c,
Fasten the screws to 3d. Note that 30 is a shoji screen.

(Effect) Therefore, according to the present invention, a new window frame is framed in a four-periphery frame shape, and mounting hardware for the upper frame and left and right vertical frames are attached to the upper frame and left and right vertical frames of this window frame excluding the lower frame. This is made in advance as a one-piece piece with the two pieces fixed together, and this one-piece piece is fitted into the old window frame from the indoor side and attached to the old window frame, so there is very little work to be done on the outside and near the window. It is possible to reduce the danger of work and increase work efficiency.

In addition, the mounting hardware for the bottom frame that is attached to the bottom frame of the old window frame by the only window installation work is integrally equipped with a mounting reference piece for the expected direction and direction of the new window frame, so it can be attached to the bottom frame of the old window frame. By simply placing the fitted new window frame against these mounting reference pieces directly or indirectly through the adjustment tool, the positioning is automatically performed and the new window frame can be installed accurately and in an aligned state. can.
