【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、旧窓枠をアルミ製等の新窓枠に取替えるため
の窓枠の改装工法に関する。TECHNICAL FIELD The present invention relates to a method for remodeling a window frame for replacing an old window frame with a new window frame made of aluminum or the like.
サッシ改装に当って、旧窓枠を撤去する場合と、旧窓枠
は残置させ、これに新窓枠を取付ける場合との２通りの
方法がある。There are two methods for removing the old window frame during the sash remodeling and for leaving the old window frame and attaching the new window frame to it.
前者の例としては特開昭58−210275号公報等のものがあ

を用いている。後者の例としては、特公昭54−27063号
公報等のものがある。An example of the former is that disclosed in Japanese Patent Laid-Open No. 58-210275, which is usually called a drawing method and uses a large and complicated tool. An example of the latter is, for example, Japanese Patent Publication No. 54-27063.
しかしながら、通常カバー工法と呼ばれる上記後者の方
式では、開口部が狭くなる難点があり、この面で前者の
方式が優れる。However, the latter method, which is usually called a cover construction method, has a drawback that the opening is narrowed, and the former method is superior in this respect.
ところが、前者の方法の場合、強引に引抜いて旧窓枠を
撤去するものであるため、前記工法にみられるように、
複雑かつ大がかりな工具を要し、しかも作業性にも難が
ある。However, in the case of the former method, it is forcibly pulled out to remove the old window frame, so as seen in the above construction method,
It requires complicated and large-scale tools, and it is difficult to work with.
そこで、本考案の目的は、簡単な工具を用いてしかも作
業性にも優れる窓枠の改装工法を提供することにある。Therefore, an object of the present invention is to provide a method for remodeling a window frame that uses a simple tool and is excellent in workability.

カー金物を、アンカー鉄筋から除去する工程と、 新窓枠を開口部に取り付ける工程と、 を有することを特徴とするものである。The present invention, which has solved the above-mentioned problems, has a structure in which an old window frame is fixed to an anchor rebar of a skeleton through an anchor metal fixture; an upper frame, a lower frame, and a left-right vertical direction which constitute the old window frame. On the prospective surface of the frame, a step of cutting an intermediate portion of the prospective width over the entire circumference along the longitudinal direction of the frame material, and a piece of the frame material individualized by this cutting, which is engaged with the anchor metal fitting. Or removing any other piece from the remaining piece by leaving the remaining piece, or if there is an integrated piece of the group of pieces that does not depend on engagement with the anchor metal piece, While releasing the engagement with the engagement piece,
Alternatively, it is characterized by including a step of removing the anchor metal piece from the anchor rebar together with the integrated remaining integrated piece, and a step of attaching a new window frame to the opening.
本発明では、従来の引抜き工法やカバー工法とは異っ
て、旧窓枠を切断することによって撤去することを主要
点としている。In the present invention, unlike the conventional drawing method or cover method, the main point is to remove the old window frame by cutting it.

さな力で足りる。As an example of removing the old window frame, first, the middle portion is cut off while leaving the inside and the outside of the old window frame. When the middle part of the old window frame is cut, the anchor metal fitting is exposed, so depending on the form of this anchor metal fitting, for example, after cutting the joint with the core rebar or without cutting,
You can easily remove it by twisting the anchor. Further, since the remaining indoor and outdoor parts of the old window frame are only bonded to the mortar part of the opening, a small force is sufficient to remove them.

性からみれば旧窓枠の撤去はきわめて容易となる。That is, in the present invention, among the pieces of the frame material that are individualized by cutting in the middle portion of the prospective width, the peaks that engage with the anchor metal fittings are left, or engage with the anchor metal fittings of the piece group. If there is one that is integrated regardless of the other, it is left alone and other pieces are separated and removed from the remaining piece, so with a small force with the anchor metal itself or the piece integrated with the anchor metal. The removal setup by twisting and twisting is completed, so that the anchor metal piece can be easily separated from the anchor rebar. Therefore, it is very easy to remove the old window frame from the viewpoint of overall workability.

費が安価でかる可搬性に優れる。On the other hand, in order to remove the old window frame, the old window frame is disassembled by cutting the entire length in the longitudinal direction. As the cutting means in this case, it is preferable to use air plasma arc fusing while using a cutting torch. As a result, unlike the case of using a rotary disc blade, the cutting torch can be reliably moved to the corner portion of the window frame, so that cutting can be performed over the entire length and no chips or slag are generated. In addition, the equipment to be used is mainly a cutting power source, an air compressor, and a cutting torch type, so the equipment cost is low and the portability is excellent.
以下本発明を図面を参照しながらさらに詳説する。 Hereinafter, the present invention will be described in more detail with reference to the drawings.
第２図および第３図は旧窓枠が残存している状態を示
す。2 and 3 show a state in which the old window frame remains.

持されている。５は仕上用モルタル、６は額縁である。That is, a reinforcing bar 2 for anchoring is embedded in a skeleton 1 such as concrete of a building, and an old aluminum window frame composed of upper and lower / left and right frames 4A to 4D is held in it by anchor metal fittings 3A to 3D. . Reference numeral 5 is a finishing mortar, and 6 is a frame.
アンカー金具3A〜3Dは、たとえば第５図の形状をなし、
本体31の両端に形成した係合片30で旧窓枠4A〜4Dの爪片
4aを挟み、他方で、起立部32と鉄筋２とを溶接すること
によって、鉄筋２に換言すれば躯体１に保持するもので
ある。The anchor metal fittings 3A to 3D have, for example, the shape shown in FIG.
Engagement pieces 30 formed on both ends of the main body 31 are used to hook the old window frames 4A to 4D.
4a is sandwiched, and on the other hand, the upright portion 32 and the reinforcing bar 2 are welded to each other so that the reinforcing bar 2 is put in another way, that is, the frame 1 is held.
旧窓枠の撤去に際しては、まず第２図および第３図のよ

エアープラズマ溶断により見込み方向に切断し第１図の
ように、室内部分40および室外部分41を残存させて、中
間部分42を取除く。これによって、アンカー金具3Aが露
出する。When removing the old window frame, first, as shown in Figs. 2 and 3, at the X and Y positions of the inner frame and the outer frame of the old window frame, use a cutter such as a rotary disk blade or preferably air plasma fusing. It cuts in the prospective direction, and as shown in FIG. 1, the indoor portion 40 and the outdoor portion 41 are left, and the intermediate portion 42 is removed. As a result, the anchor metal fitting 3A is exposed.
その後、露出したアンカー金具3Aを、第４図のように、
強く捩り回して鉄筋２と強度的に弱い溶接部分において
破断させるか、前述のとおり中間部分42を取り除いた

ながら取除く。After that, the exposed anchor metal fitting 3A, as shown in FIG.
Twist it strongly to break it in the welded part weak in strength with the reinforcing bar 2, or after removing the intermediate part 42 as described above, chip the mortar 5 part around the anchor metal fitting 3A,
After cutting the reinforcing bar 2 by inserting a fusing torch from the space created by this to melt the reinforcing bar 2 and the like, the anchor metal fitting 3A is twisted and twisted, whereby the remaining indoor part 40 and outdoor part 41 and the anchor metal fitting 3A are separated. Remove while disengaging.
次いで、室内部分40および室外部分41をペンチ等把持具
によって把持し引き抜くなどの方式によって除去する。
このとき、それらの部分40,41は付着部分が少ないので
除去に要する力は小さい。Then, the indoor portion 40 and the outdoor portion 41 are removed by a method such as grasping with a grasping tool such as pliers and pulling out.
At this time, since the portions 40 and 41 have few adhered portions, the force required for removal is small.
なお、中間部分42を除去した後、アンカー金具3Aとの係
合を解きながら室内外部分40,41の除去を行い、次いで
アンカー金具3Aの除去を行うようにしてもよい。After removing the intermediate portion 42, the indoor and outdoor portions 40 and 41 may be removed while releasing the engagement with the anchor metal fitting 3A, and then the anchor metal fitting 3A may be removed.
かくして、第６図のように、躯体１に鉄筋２のみが露出
した開口部が得られる。Thus, as shown in FIG. 6, an opening in which only the reinforcing bar 2 is exposed is obtained in the frame 1.
その後は、鉄筋２にアルミ等の新窓枠４′Ａに固定した
新アンカー金具３′Ａを溶接等により一体化し、新窓枠
４′Ａを取付ける。After that, the new anchor metal fitting 3'A fixed to the new window frame 4'A such as aluminum is integrated with the reinforcing bar 2 by welding or the like, and the new window frame 4'A is attached.
他の下、および左右部分においても同様な施工が行なわ
れる。なお、鉄筋２を使用せずに、モルタルまたは躯体
にホールインアンカーを打込み、これに新窓枠のアンカ
ー金具を溶接することもできる。Similar construction is performed under the other parts and on the left and right parts. It is also possible to drive a hole-in anchor into the mortar or the body without using the reinforcing bar 2 and weld the anchor metal fitting of the new window frame to this.

去するものである。By the way, in the present invention, although the window frame removal method of the above example is optimal, as shown in FIG.
After air plasma fusing along the Z line in the middle part of the main body of 4A, the outdoor portion 41 'is tilted in the direction of arrow P, and the claw piece 4a of the outdoor portion 41' is removed from the anchor metal fitting 3A.
The indoor part 40 'may be removed together with the frame 6 by forcibly moving it toward the room as indicated by the arrow Q.
Alternatively, the outdoor portion 41 'may be tilted in the P direction and the indoor portion 40' may be tilted in the R direction to be removed from the anchor fittings 3A. In these cases, the indoor portion 40 'or the outdoor portion 41' is disengaged from the anchor metal fitting 3A in advance, and then the anchor metal fitting 3A is removed from the anchor rebar 2.
また、第10図は、本発明の個別化された枠材のピース群
