Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a removing method, a covering method and other methods are conventionally employed as a method for remodelling a metal sash which has been deteriorated with an elapse of time but none of currently-employed methods are hardly said to be decisive and no other decisive methods are used. <P>SOLUTION: In a novel method, the whole or only an exposed part of a sash frame to be remodelled is removed, and an anchor plate attached to an outside frame requiring a structural strength is directly connected and hooked on a structural wall by using a recessed anchor or the like and an inside frame member can be installed by one touch work with a buckle without using a small screw or the like. In such a constitution, a good appearance without exposing the head of the screw or the like is obtained. A peripheral wall, floor or the like scarcely need be repaired so that environmental pollution accompanying removal work and the total costs of work such as incidental repair expenses for repairing, work time at a site and the like can be reduced. Remodeling work can be executed while a resident is present in the dwelling with consideration of living environment. <P>COPYRIGHT: (C)2003,JPO

As a method, cut out only the existing frame embedded in the wall etc. and the mortar around it with a cutting tool,
Alternatively, if only the exposed parts are cut out together with the frame and a new frame suitable for the removed part is attached, breakage defects such as the wall floor of other parts due to the removal can be prevented, and the time and cost required for repair can be greatly reduced. It has become possible to implement construction methods that reduce construction pollution such as vibration, noise, dust, and stains, in addition to being able to reduce emissions.

る。First, when the existing frame (A) is installed parallel to the walls (a, b, c), the mortar (a2, b2) including the outer peripheral joint portion is also removed, and the frame is installed at a right angle. If it is done, remove the exposed parts of the four circumferences that contact the finishing material (a, b, c) and the filling mortar (a 2, b 2) and remove it by installing a new frame corresponding to the removal part (A 2) Without damaging the walls (I, R, C) due to the construction method, the wall floor (I, R, C)
D, E) The time and cost required for repair can be significantly reduced.

There are various types of finishing materials (a, b, d, ho) for floors (d, b, d) and mortar, tiles, stones, boards, etc. The existing frame (A) in contact with the entire existing frame (A) is cut and cut off using the well-known disc sander (I2) and the like, and the existing frame (A) and finishing materials (A, B, D, E) and anchors (D31) are cut off. However, how to suppress construction pollution due to noise (Z3), dust (Z4), etc. generated by using the disk sander (I2) is a decisive factor for the success of the remodeling method.
