Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an old window frame removal device implemented in the renovation of a window equipped with a rectangular old window frame formed by an upper frame part, a lower frame part, and left and right vertical frame parts. It is something.

In general, most of the old windows that are subject to renovation are old windows with old iron window frames, and the upper frame, lower frame, and left and right vertical frames of the old window frames are The old window frame is welded together to form a rectangular shape, and is welded via anchors to an embedded metal body embedded in the concrete wall of the building structure.

To renovate an old window with an existing old window frame as described above, there are two methods: removing the architectural structure and then replacing the old window frame with a new window frame, and leaving the old window frame in place. A conventionally known method is to cover the old window frame with a cover renovation method. The former renovation method had the problem that the work was extremely complicated and large-scale, and it also caused cracks to occur. In addition, in the latter renovation method, the corrosion of the old window frame itself continues to progress, which tends to cause rust to ooze out onto the surface of the building structure.Also, if the new window frame is made of aluminum alloy, the old window frame There was a problem that corrosion was likely to occur due to contact with the windows, and that the window openings after renovation became narrower.

The present invention was invented in view of the above-mentioned conventional problems, and its purpose is to enable renovation without leaving the old window frame, and to be able to remove the old window frame compared to the chisel method. This not only simplifies the construction work, but also prevents cracks from occurring.Furthermore, it is possible to reliably accommodate old window frames with different widths in the indoor and outdoor directions, and to connect the indoor and outdoor mounting parts to the outdoor and indoor sides of the frame. To provide an old window frame removal device which can be attached to the inside and can be pulled out equally from the outdoor side and the indoor side.

The old window frame removal device of the present invention has a removing means 4 for pulling and removing the old window frame 1, and a frame part 1 of the old window frame 1.
A mounting part 6 is provided on each of the indoor side and the outdoor side of a, and the facing distance between the indoor side mounting part 6 and the outdoor side mounting part 6 is adjustable. By adopting such a configuration, the above-mentioned object of the present invention is achieved. That is, in the present invention, the frame part 1a can be removed by attaching the attachment part 6 to the frame part 1a of the old window frame and pulling it with the removal means 4, and in this case, the indoor side and the outdoor side of the frame part 1a can be removed. Since the attachment part 6 is attached to each side and pulled, the outdoor side and the indoor side of the frame part 1a are pulled equally, making it possible to pull out accurately. Furthermore, since the facing distance between the indoor-side mounting part 6 and the outdoor-side mounting part 6 is freely adjustable, by adjusting this distance, it is possible to accommodate various indoor and outdoor widths of the frame part 1a. Thus, the attachment part 6 can be reliably attached to the outdoor side and the indoor side of the frame part 1a.

The present invention will be explained in detail below with reference to Examples. The attached drawing shows an example of an iron window frame as the old window frame 1. A part of the old window frame 1 is buried or attached to an architectural structure 2 such as a concrete wall. 1st
The figure shows an example of an old window frame removal device 4 according to the present invention. In the drawing, legs 30 protrude from both ends of the central base 29, and the tips of the legs 30 serve as the abutment members 21. An elastic member 31 such as rubber is provided on the distal end surface of the abutment member 21. A removal means 4 is attached to the central base 29. The removal means 4 is constituted by a threaded rod 24, which is movably attached to a central base 29. At the tip of the threaded rod 24, which is the removing means 4, there are mounting parts 6 for mounting on the indoor side and the outdoor side of the frame part 1a of the old window frame 1, respectively. When attaching the attachment part 6, in the embodiment shown in the drawings, a hole 1d is made in the frame part 1a and this hole 1 is
d, the attachment part 6 is inserted into the frame part 1a, but it is not necessarily limited to the above embodiment, and other attachment parts can be used as long as the attachment parts 6 on both sides are attached to the indoor side and the outdoor side of the frame part 1a. It is possible to adopt the following mounting method. Here, the facing distance between the indoor side and outdoor side mounting parts 6 is adjustable (that is, the dimension can be adjusted in the direction of the arrow in Fig. 1), and this facing distance can be adjusted. This allows it to be attached to frame portions 1a of various widths. However, in the above embodiment, the abutting members 21 at the tips of the legs 30 on both sides
With the frame 1a in contact with the building structure 2, attach the attachment parts 6 to the outdoor and indoor sides of the frame 1a, and then operate the handle 24a provided on the threaded rod 24 to move the threaded rod 24 and attach the frame 1a. The outdoor side and the indoor side of the portion 1a are simultaneously pulled and pulled out using the attachment portion 6. In this way, each frame 1
The old window frame 1 is removed by pulling out each part a separately.

After the old window frame 1 is removed using the old window frame removal device 4 of the present invention as described above, a new window frame 3 is attached to the part where the old window frame 1 was removed. Fig. 2 shows an example of attaching a new window frame 3, and the one shown in the upper half of Fig. 2 uses reinforcing bars 35 left in the area where the old window frame 1 has been removed to install an intermediate interposition. The metal material 64 is welded to the mounting bracket 65 attached to the new window frame 3, and the one shown in the lower half of FIG. Fix it with bolts 40, etc., and attach the new window frame 3 to this fixing bracket 66.
It is designed to be installed. Of course, the new window frame 3 may be attached using various attachment methods other than those described above. Further, the recess after the removal of the old window frame 1 is filled with a heat insulating material 62. As a heat insulating material, a foamed synthetic resin such as urethane is injected and foamed into the recess, or glass wool or the like is filled. Reference numeral 67 in FIG. 2 indicates a picture frame.

In the present invention, as described above, the removal means for pulling and removing the old window frame is provided with attachment parts for attaching it to the indoor side and the outdoor side of the frame part of the old window frame, respectively, and Since the facing distance between the mounting part and the outdoor mounting part can be adjusted, renovations can be made without leaving the old window frame, and when removing the old window frame, the construction work is simpler compared to the chisel method. In addition to being able to be used in a variety of ways, it does not cause cracks or the like. Moreover, since the attachment parts are attached to the indoor and outdoor sides of the frame and pulled, the outdoor and indoor sides of the frame are tensioned evenly, making it possible to pull out accurately. In addition, the facing distance between the indoor and outdoor mounting parts can be adjusted freely, so by adjusting this distance, it can be used even if the indoor and outdoor widths of the frame parts are different. Corresponding to this, the attachment part can be reliably attached to the outdoor side and the indoor side of the frame part.
