JPS595751B2 - Construction method for replacement sash - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a replacement sash in which an existing sash is removed and then renovated into a new sash. The outside of the frame is removed by pushing it inward, resulting in damage caused by rainwater intruding into cracks and the interface of new mortar being filled into the demolished wall, and damage caused by filling the damaged wall with mortar inside and outside. However, there are drawbacks such as the need to carry out waterproofing spraying, etc., which is time-consuming and increases costs.

This invention was developed in order to solve the above-mentioned conventional problems, and its purpose is to repair the damaged wall without damaging the mounting wall by pulling out and removing the sash in the in-plane direction with a smaller force. To provide a method of constructing a replacement sash that eliminates finishing work, makes the work efficient, improves rain protection, and can be installed at low cost.

Hereinafter, when this invention is applied to the existing sashes shown in FIGS. 1 and 2, the upper frame 2, the lower frame 3, and the left and right vertical frames are first moved near a part of the corner of the existing frame 1 so that they can be pulled out more easily. 4
Cut it with a cutting machine and make a cut 5 into straight member A and corner member B. Next, the upper, lower, left and right straight members A can be pulled out, and then corner member B at the four corners can be pulled out in this order. 1. The existing frame 1 is sequentially removed from the sash mounting wall 6 by pulling it inward in the frame plane as shown by the arrows in FIG.

Next, the mounting tool 7 exposed on the existing frame trace of the sash mounting wall 6
As shown in FIG.
The new frame 9 is connected to the sash mounting wall 6 by welding, etc.
Fixed to.

Then, the gap between the new frame 9 and the sash mounting wall 6 is filled with mortar 13, and the outdoor opening is closed with caulking agent 14.

In the above configuration, the upper, lower, left and right sides of the existing frame 1 are cut near a part of the corner, and the corner member B is attached to the sash mounting wall 6.
By making the corner member B separate from the straight member A, the corner member B can be easily attached without being pulled out inward of the frame surface and damaging the mounting surface of the sash mounting wall 6. I can put it out.

Furthermore, although the linear member A is connected to the sash attachment wall 6 via the fixture 7, it can be removed smoothly by pulling it out in the direction of the frame surface without damaging the mounting surface of the sash attachment frame 6.

Therefore, when dismantling and removing the existing frame 1, the sash mounting wall 6
Since the mounting surface of the frame 9 is not damaged so much and the inner and outer finished surfaces are not damaged, the installation and finishing of the new frame 9 can be easily and quickly done using the inner and outer finished surfaces as they are, and the construction time can be significantly shortened.

Furthermore, compared to the conventional cover construction method in which the existing sash is left as is and the new sash is installed after removing the existing sash, the window opening can be made larger, and since the old sash is not used as the mounting board, the installation strength is improved. Excellent durability.

Furthermore, in this invention, the existing frame can be dismantled and removed by the simple operations of cutting and pulling out as described above, and a new frame can be easily installed based on the state of removal. can be used as is, and replacement sash construction can be done simply, quickly, and cheaply.

Claims (1)

[Claims] 1. Cut the upper, lower, left, and right frames near a part of the existing frame corner to separate them into a straight member and a corner member, then pull out the straight member and the corner member in the direction of the frame surface, and attach the existing frame to the sash mounting wall. A method for constructing a replacement sash, which comprises removing the sash from the body, and then attaching a new sash to the sash mounting wall so as to cover the area where the existing sash frame was pulled out.
