Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for renovating a window frame, and particularly to a method for renovating a window frame that is suitable for replacing a plastic window frame onto an existing copper window frame.

Traditionally, 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. In this case, the general method is to remove the old existing window frame and replace it with a new window frame, and to install the new window frame on top of the trench where the existing window frame remains. The method of installing a new window frame is complicated and uneconomical, as it involves folding the concrete wall around the window to remove the old window frame, and using special equipment to pull the window frame completely out of the frame.

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 then fixed. Conventional construction methods for this removal 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 simply connecting it with mounting brackets does not provide enough strength to shatter it, and mechanical The structure must be complicated in order to provide sufficient strength. Furthermore, the biggest concern is that parts of the plastic window frame may discolor or deteriorate due to the heat effects of welding. Therefore, new window frames other than aluminum sash have traditionally not been used in the construction methods described above.

In view of the above-mentioned problems, the inventors of the present invention conducted various tests on the construction method of using a glass window frame on an old existing window frame. The inventors have discovered that the above problem can be solved by connecting the reinforcing metal fittings to a part of the existing window frame via the metal reinforcing metal fittings, and have come to provide the present invention.

That is, the present invention is a window frame renovation method characterized by connecting at least a portion of the plastic window frame and a reinforcing metal fitting onto a mounting member via a mounting metal fitting.

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.

In addition, reinforcing metal fittings are supported on the plastic window frame used, and the metal fittings and mounting members, such as anchor bolts (
The mechanical strength of the plastic window frame can be increased and the thermal effects caused by welding can be reduced because the mounting hardware connected to the existing window frame (base hardware) or the existing window frame is connected by welding, etc. . Furthermore, the most preferred embodiment of the present invention is to insert a heat insulating sheet between the glass window frame and the mounting fittings in contact with the window frame, thereby reducing the thermal effects on the plastic window frame. It can be completely prevented.

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 mounted 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 thick line area 1 is an existing steel window frame.

3 and 8'i11. Mounting brackets (B!/ are accessory mounting brackets), 4 and 4' are accessories (4 is a cover, 4' is a drain cap, and 5 and 5' are reinforcing brackets. In the construction method of the present invention, the existing steel A mounting bracket 8 is connected to a part of the window frame (and/or base hardware 6).In this case, the material of the mounting bracket 8 is generally iron.There are no particular restrictions on the shape and number of the mounting bracket 8. For example, in FIG. 1, an L-shaped angle is shown, but it may be selected as appropriate depending on the shape of the window frame, li M, etc.

Regarding the installation method, in Fig. 1, a broken metal fitting 8 is connected to a part of the existing steel window frame 2 (and/or base metal fittings 6) by welding, and another number clasp 8'
Although the most commonly used extension method is shown, in which the parts are connected by welding, the attachment method is not limited to welding, but methods such as using narrower bolts can also be used.

On the other hand, a reinforcing metal fitting 5' is supported on the plastic window frame l. In this case, the reinforcing metal fittings are generally bolted to the plastic window frame l. By adopting such a structure, the mechanical strength of the plastic window frame 1 can be increased.

In the construction method of the present invention, the plastic window frame l and the reinforcing metal fittings 5 are
and are connected to the existing window frame 2 via a mounting fitting 8'. By doing so, it is possible to maintain the mechanical strength of the plastic window frame 1 while preventing heat effects caused by welding or the like. In this case, the mounting metal fitting 3' and the reinforcing metal fitting 5 are generally fastened with bolts, but there is no particular restriction on the method, such as bonding.

In the construction method of the present invention as shown above, the material of the new window frame is made of plastic such as vinyl chloride, and when connecting the mounting bracket to the existing window frame, strength is required, so welding is not required. Since the method is commonly used, the primary concern is that plastic window frames will deteriorate due to thermal effects during welding. Therefore, it is necessary to devise ways to avoid this influence.

For this purpose, for example, in the case of the construction method shown in Fig. 1, after bath-bonding the mounting bracket 8, the existing window frame, the base hardware 6, the connection parts 7, 8, 9 of the metal fitting 3', and the IO, It is preferable to fasten the mounting bracket 8' and the reinforcing bracket 5 with one bolt. Also,
If it is structurally necessary to weld the mounting bracket 8' and the reinforcing bracket 5 after tightening them, it is preferable to insert a heat insulating sheet 11 between the mounting bracket 8' and the plastic window frame. . Asbestos or the like is used as the heat insulating sheet.

The present invention has the above-mentioned characteristics, and other construction methods, such as assembly order, accessories (cover 4.

It is also possible to adjust the temperature between the first and second heats as desired by removing the cover 4 or 4'.
