ばよい。 DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window frame renovation method, and more particularly to a window frame renovation method suitable for attaching a plastic window frame onto an existing steel window frame. Conventionally, steel window frames have been the mainstream for building window frames. However, as these window frames age, problems arise such as their appearance worsening due to corrosion and problems such as opening and closing not being smooth, so if a certain period of time has passed, it is necessary to replace them with new steel window frames or aluminum sash. It will be done. Generally, two methods are used at this time: removing the old existing window frame and installing a new window frame, and leaving the existing window frame in place and installing a new window frame on top of it. The method of installing a new window frame is complicated and uneconomical, as it requires scraping the concrete wall around the window to remove the old window frame, and using special equipment to warp the window frame from the frame and pull it out. . Therefore, this method is mainly used when the old window frame is completely unusable due to a decrease in strength, etc., but in cases where the existing window frame is still usable due to its strength, a new window frame is installed on top of the window frame. The window frame is installed. Conventional construction methods used in this case include directly welding the existing window frame and the new window frame, or connecting the two window frames using mounting hardware. According to this construction method, the new window frame can be applied as long as the window frame itself has excellent strength and heat resistance, such as aluminum sash. However, when using a window frame made of plastic such as vinyl chloride, the plastic window frame itself lacks strength and heat resistance, so the strength of the new frame cannot be achieved by simply connecting it with mounting brackets, and the mechanical The structure must be complicated in order to provide sufficient strength. A further concern is that some parts of the plastic window frame may discolor or deteriorate due to the thermal effects of welding. Therefore, new window frames other than aluminum sash are conventionally constructed using the construction methods described above.
It was never used. In view of the above-mentioned problems, the inventors of the present invention have studied various construction methods for using plastic window frames on old existing window frames, and have found that after attaching the mounting bracket in a specific manner to the mounting bracket attachment part of the plastic window frame, The inventors have discovered that the above problem can be solved by welding the mounting bracket onto an existing window frame, and have thus come to provide the present invention. That is, the present invention provides a method for refurbishing a window frame in which a plastic window frame is attached to an existing window frame via a mounting bracket, in which a reinforcing bracket is positioned inside the mounting bracket attachment part of the plastic window frame, and the plastic window frame is After joining the mounting part of the window frame and the mounting bracket with a heat insulating sheet interposed between them, and bolting the reinforcing metal fittings, the mounting part of the plastic window frame, the heat insulating sheet, and the mounting bracket, the mounting This is a method for renovating plastic window frames, which is characterized by directly or indirectly welding metal fittings onto the existing window frame. According to the present invention, since the existing window frame is used as is, there is no need to remove the window frame. Therefore, the construction period can be shortened and it is economical. The biggest feature of the present invention is that after the mounting bracket is joined to the plastic window frame with a heat insulating sheet interposed between them and bolted, the mounting bracket is directly or indirectly welded onto the existing window frame. be. By adopting such measures, it is possible to completely prevent thermal effects on the plastic window frame when the mounting bracket is welded onto the existing window frame. Hereinafter, the construction method of the present invention will be explained in detail based on the drawings. FIG. 1 is a diagram showing a plastic window frame installed on an existing window frame using the construction method of the present invention.
In the figure, the shaded area 1 is a plastic window frame made of vinyl chloride or the like, and the bold line area 2 is an existing steel window frame. 3 and 3' are mounting brackets (3'' is accessory mounting bracket),
4 and 4' are accessories (4 is a cover, 4' is a draining cover), 5 is a reinforcing metal fitting, and 5' is an accessory (cover) mounting metal fitting. In the construction method of the present invention, the mounting bracket 3 is connected to a part of the existing steel window frame 2 (and/or base hardware 6). In this case, the material of the mounting bracket 3 is generally iron. The shape and number of the mounting fittings 3 to be used are not particularly limited. For example, although FIG. 1 shows an embodiment using an L-shaped angle, it may be selected as appropriate depending on the shape and weight of the window frame. Also, regarding the installation method, Figure 1 shows the existing steel window frame 2.
The most commonly used mode is shown in which the mounting bracket 3 is connected to a part of the base metal fitting 6 (and/or the base hardware 6) by welding, and further, another mounting bracket 3' is connected to the mounting bracket 3 by welding. On the other hand, a reinforcing metal fitting 5 is positioned inside the mounting part 3' of the plastic window frame 1 , and a heat insulating sheet 11 is interposed between the fitting part 3' of the plastic window frame 1 and the mounting part 3'. The reinforcing metal fittings 5, the mounting portion of the plastic window frame 1 , the heat insulating sheet 11, and the mounting metal fittings 3' are bolted together. With such a structure, the mechanical strength of the plastic window frame 1 can be increased. In addition, in the present invention, the attachment portion of the plastic window frame 1 and the mounting bracket 3' are joined with a heat insulating sheet 11 made of asbestos or the like interposed therebetween, and the reinforcing metal fitting 5 and the plastic window frame 1 are bonded together. installation site, insulation sheet 11 and mounting bracket 3'
After tightening the bolts, the mounting bracket 3' is welded directly or indirectly (for example, indirectly via another mounting bracket 3) onto the existing window frame 2 . By doing this, when connecting the mounting brackets 3' and 3 to the existing window frame 2 by welding, the welding heat is transmitted through the mounting brackets to the newly installed plastic window frame such as vinyl chloride, thereby preventing deterioration. This can be prevented from becoming a cause. In addition, in FIG. 1, the symbols 7, 8, 9 and 1
0 indicates a welded connection. The present invention has the above characteristics, and other matters such as accessories (covers 4, 4')
, caulking material 12, etc., may be appropriately employed.
