Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for renovating an existing window frame into a new window frame.

Conventionally, various renovation methods have been known as methods for renovating an existing window frame into a new window frame when it becomes obsolete.

For example, the window frame mounting part where 6 frames of the existing window frame are installed,
After demolishing and removing 6 frames by chisel work and installing 6 frames of new window frames in the demolished parts, mortar etc. is injected between the frames and the window frame attachment part to firmly attach the frames, and the demolished parts are A renovation method that involves repairing windows and installing new window frames to make them look better.

In addition, the renovation method involves pulling the six frames of the existing window frame inward in the frame plane, pulling them out from the window frame attachment part, attaching the frame of the new window frame, and then repairing the frame attachment part with mortar or the like.

Furthermore, a so-called cover renovation method is known in which a new window frame is attached to an existing window frame using a fixture.

However, with the second renovation method, a large impact sound is generated during the chisel work, which creates a lot of noise, and fragments of the window frame attachment part, such as concrete, are scattered around, which is dangerous.
Furthermore, since the chiseling work takes time, the construction period becomes longer, and since it damages the window frame attachment part and the interior, there are problems such as repair work having to be carried out after the new window frame is installed. If so, when you pull out the frame of an existing window frame, the part that protrudes inward from the window frame attachment part of the other frame will get in the way. Since the underframe is pulled out and removed, it takes a long time to pull it out and remove it, lengthening the renovation period.Furthermore, it is necessary to repair the 6-point attachment part of the new window frame.
It has problems such as troublesome repair work.

As described above, in the first and second renovation methods, the underframe of the existing window frame is removed by tearing it down and pulling it out, which increases the removal work time and the construction period. At the same time, when removing the underframe, the protruding parts of other frames get in the way, making it difficult to enlarge the work space, making it difficult to perform lifting and pulling operations. In addition, the first and second renovation methods have problems such as having to be repaired, making the repair work troublesome, and there is no standard part when installing a new window frame with the first and second renovation methods. It also has the disadvantage that it is difficult to install it correctly.

In the third renovation method, the opening area of the new window frame becomes smaller by the dimension of the part that protrudes from the window frame attachment part of the existing window frame, resulting in insufficient lighting after the new window frame is installed. At the same time, hollow parts are formed between the underframe of the existing window frame and the underframe of the new window frame by the protruding parts, so the new window frame resonates, reducing the soundproofing properties and the heat insulation properties. It has problems such as deterioration.

The present invention was made in view of the above circumstances, and its purpose is to allow window frame renovation work to be carried out in a relatively short period of time, without damaging the window frame mounting part or the interior, and after installing a new window frame. There is no need to perform repair work, and the new window frame can be correctly positioned and installed using a part of the existing window frame as a reference, and a part of the existing window frame can be used as an anchor for installing the new window frame. To provide a method for renovating a window by which a new window frame can be easily installed at low cost, and sufficient light can be obtained without reducing the opening area of the new window frame.
