Description

本発明は建物の既存サッシを新規サッシに交換するサッシの交換方法及びサッシの交換構造に関する。   The present invention relates to a sash replacement method and a sash replacement structure for replacing an existing sash of a building with a new sash.

住宅などの建物の改築工事等において、建物外周部の開口部に設けられた既存サッシを新規サッシに交換することがしばしば行われる。鉄骨軸組に対し軽量気泡コンクリートパネルからなる外壁を取付けて構成された建物では、例えば特許文献１に記載のように開口部の周囲にフレームが配置されており、既存サッシは該フレームに取り付けられた状態となっている。このような構成の建物の場合、サッシ周りの軒天、シーリング、石膏ボードにクロスを貼付するなどして構成された内装壁、木下地、開口枠を順次解体して既存サッシを開口部のフレームごと撤去し、新規サッシを取付けた後、木下地、開口枠、内装壁、軒天、シーリングを復旧させていく工法を採用することができ、このような工法によれば新築同様の仕上がりが得られる。しかし、この工法では、工事内容が大規模になるため、工期が長くかかり、コストが嵩むという問題があった。   In renovation work of a building such as a house, it is often performed to replace an existing sash provided at an opening in the outer periphery of the building with a new sash. In a building constructed by attaching an outer wall made of a lightweight cellular concrete panel to a steel frame, a frame is arranged around the opening as described in Patent Document 1, for example, and an existing sash is attached to the frame. It is in the state. In the case of a building with such a structure, the interior wall, wood base, and opening frame constructed by attaching a cloth to the eaves, sealing, and gypsum board around the sash are disassembled in order, and the existing sash is opened to the frame of the opening. After installing the new sash, it is possible to adopt a method that restores the wood substrate, opening frame, interior wall, eaves, and ceiling. According to such a method, a finish similar to a new construction can be obtained. It is done. However, this construction method has a problem that the construction content is large and the construction period is long and the cost is increased.

そこで、既存サッシのサッシ枠は撤去するが、開口部のフレームは残して新規サッシ枠に取り替える簡易な工法が採られることもある。しかし、かかる工法においても、従来は、サッシ枠の解体時に、サッシ周りの内装壁、木下地、開口枠を解体し、また新規サッシ枠の取付け後、木下地、開口枠、内装壁を取付けていたため、相応の工期、コストが必要であった。   Therefore, although the sash frame of the existing sash is removed, a simple construction method may be adopted in which the frame of the opening is left and replaced with a new sash frame. However, even in this method, conventionally, when disassembling the sash frame, the interior wall, wood base, and opening frame around the sash are dismantled, and after installing the new sash frame, the wood base, opening frame, and interior wall are attached. As a result, a reasonable construction period and cost were necessary.

また上記工法において、内装壁、木下地、開口枠を解体せずに、既存サッシ枠のみを撤去することは可能であるが、新規サッシ枠と既存開口枠との納まりが悪く、隙間が発生してしまうという問題があった。   In the above construction method, it is possible to remove only the existing sash frame without dismantling the interior wall, the wood substrate, and the opening frame, but the new sash frame and the existing opening frame are not well accommodated, and a gap is generated. There was a problem that.

なお、本発明に関連する先行技術としては特許文献２が知られている。しかし、特許文献２は、電磁波の浸入や漏洩を防止するための電磁波遮断構造に関するもので、サッシの交換方法や交換されたサッシ構造に関するものではない。また、サッシ取付構造に特許文献２の構造を利用したとしても、カバー材を開口枠及び／又は壁にねじにより固着するために、新規開口枠にねじ頭が露出してしまい、美観を損ねるという問題がある。
実公昭５７−２４８１３号公報 特開平７−０９４８９３号公報 Patent Document 2 is known as a prior art related to the present invention. However, Patent Document 2 relates to an electromagnetic wave blocking structure for preventing electromagnetic wave intrusion and leakage, and does not relate to a sash replacement method or a replaced sash structure. Moreover, even if the structure of Patent Document 2 is used for the sash mounting structure, the cover material is fixed to the opening frame and / or the wall with screws, so that the screw head is exposed to the new opening frame, and the appearance is impaired. There's a problem.
Japanese Utility Model Publication No. 57-24813 Japanese Unexamined Patent Publication No. 7-094893

本発明は、上記事情に鑑みてなされたもので、開口部のフレーム、サッシ周りの内装壁、木下地、開口枠を解体することなく、既存サッシを新規サッシに短納期でかつ簡易に交換することができるサッシの交換方法を提供することを目的とする。
本発明はまた前記サッシの交換方法によって交換されたサッシの交換構造を提供することも目的とする。 The present invention has been made in view of the above circumstances, and easily replaces an existing sash with a new sash with a short delivery time without disassembling the frame of the opening, the interior wall around the sash, the wood substrate, and the opening frame. An object of the present invention is to provide a sash replacement method that can be used.
Another object of the present invention is to provide a sash exchange structure exchanged by the sash exchange method.

第一の発明によれば、既存サッシを新規サッシに交換する方法において、
（ａ）既存開口枠と既存サッシ周囲の外壁構造を残存させたまま前記既存サッシを撤去する工程と、
（ｂ）前記既存サッシに比べ開口枠取付片の内法寸法が小さな新規サッシを準備する工程と、
（ｃ）前記既存サッシと前記新規サッシの開口枠取付片の内法寸法の差に対応した厚みを有するカバー式の新規開口枠を前記既存開口枠に重ね合わせて貼付する工程と、
（ｄ）前記新規サッシを前記残存した外壁構造に取付ける工程と
を具備してなる方法が提供される。 According to the first invention, in a method of replacing an existing sash with a new sash,
(A) removing the existing sash while leaving the existing opening frame and the outer wall structure around the existing sash;
(B) preparing a new sash having a smaller inner dimension of the opening frame mounting piece than the existing sash;
(C) a step of attaching a cover-type new opening frame having a thickness corresponding to a difference in internal dimensions of the opening frame mounting pieces of the existing sash and the new sash so as to overlap the existing opening frame;
(D) attaching the new sash to the remaining outer wall structure.

ここで、サッシとは、建物の内外を区画する窓ガラスを直接あるいは間接的に保持する枠のことをいう。間接的に保持する場合とは、例えば窓ガラスが開閉するタイプの場合であり、サッシは窓ガラスを直接保持するのではなく窓ガラス周囲の框を保持する。
また、開口枠とは、サッシの室内側の周縁部に沿って取り付けられ内装壁とサッシとを見切る部材であり、通常は略長方形断面の木質系あるいは合成樹脂系の長尺の材料からなる。そして断面長手方向が外壁面と直角をなすようにロ字状に組み合わせて、室内側の端部が内装壁面から突出するように設置される。
また、外壁構造とは、建物の外周部に設けられた外壁自体と、外壁に付帯したサッシが設置される外壁の開口部近傍の付帯構造、例えば、外壁の開口部周縁（外壁と開口部との境界部分）に沿って設けられたフレームなどを含む。
第一の発明では、既存開口枠と外壁構造を残存させるが、既存開口枠に新規開口枠を重ね合わせて貼付するので、開口枠にビス等の金具が露出することはなく、良好な美観が保てる。 Here, the sash refers to a frame that directly or indirectly holds the window glass that partitions the inside and outside of the building. The case of indirectly holding is, for example, a type in which the window glass is opened and closed, and the sash does not hold the window glass directly, but holds the wrinkles around the window glass.
The opening frame is a member that is attached along the peripheral edge on the indoor side of the sash and that covers the interior wall and the sash, and is usually made of a long material having a substantially rectangular cross section of wood or synthetic resin. And it installs so that the edge part of an indoor side may protrude from an interior wall surface, combining in a square shape so that a cross-sectional longitudinal direction may make a right angle with an outer wall surface.
In addition, the outer wall structure is an outer wall provided on the outer periphery of a building and an incidental structure in the vicinity of the opening of the outer wall where a sash attached to the outer wall is installed, for example, the outer periphery of the opening of the outer wall (the outer wall and the opening). Frame provided along the boundary portion).
In the first invention, the existing opening frame and the outer wall structure remain, but since the new opening frame is overlapped and pasted on the existing opening frame, a metal fitting such as a screw is not exposed to the opening frame, and a good aesthetic appearance is obtained. I can keep it.

第二の発明によれば、第一の発明の工程（ｃ）において、前記新規開口枠と前記既存開口枠との間に、弾力性を有する接着層を介在させることを特徴とする方法が提供される。
ここで、接着層は、化学硬化型接着剤や発泡接着剤等、任意の接着剤を、既存開口枠と新規開口枠の間に何らかの手段で介在させたものであり、接着剤のテープを用いても流動性のある接着剤を用いても構わない。また新規開口枠と既存開口枠との間に接着層を介在させる具体的方法は任意であり、接着剤のテープを用いる場合は、既存開口枠の表面に全面に亘って接着剤テープを貼付していき、その上から新規開口枠を被覆することが可能であり、流動性のある接着剤を用いる場合には、既存開口枠と新規開口枠との間にスペーサを介在させ、形成された間隙に接着剤を注入していくことができる。
第二の発明では、接着層により新規開口枠を既存開口枠に取付けているので、新規開口枠の表面に取付ビス等が露出するおそれはなく、良好な美観が担保される。また、接着層は弾力性を有するため、施工に起因する寸法誤差を吸収することができるので新規開口枠の納まりが良好である。 According to the second invention, there is provided a method characterized in that in step (c) of the first invention, an elastic adhesive layer is interposed between the new opening frame and the existing opening frame. Is done.
Here, the adhesive layer is obtained by interposing an arbitrary adhesive such as a chemical curable adhesive or a foamed adhesive between the existing opening frame and the new opening frame by any means, and using an adhesive tape. Alternatively, a fluid adhesive may be used. The specific method of interposing the adhesive layer between the new opening frame and the existing opening frame is arbitrary, and when using an adhesive tape, the adhesive tape is applied to the entire surface of the existing opening frame. It is possible to cover the new opening frame from above, and when using a fluid adhesive, a gap is formed by interposing a spacer between the existing opening frame and the new opening frame. Adhesive can be injected into
In the second invention, since the new opening frame is attached to the existing opening frame by the adhesive layer, there is no possibility that the mounting screw or the like is exposed on the surface of the new opening frame, and a good aesthetic appearance is ensured. In addition, since the adhesive layer has elasticity, it can absorb a dimensional error caused by construction, so that the new opening frame fits well.

第三の発明によれば、第一又は第二の発明において、前記既存開口枠の室内側端部は、内装壁表面から突出した構成であり、前記新規開口枠は、前記既存開口枠の露出面を覆う略Ｊ字状断面を有することを特徴とするサッシ交換方法が提供される。
第三の発明では、新規開口枠の断面形状を既存開口枠の露出部分に対応させて略Ｊ字状としたので、容易に既存開口枠を覆い隠すことができ、手間をかけずに良好な美観を確保することができる。 According to a third invention, in the first or second invention, the indoor side end portion of the existing opening frame protrudes from the interior wall surface, and the new opening frame is an exposure of the existing opening frame. There is provided a sash exchange method characterized by having a substantially J-shaped cross section covering the surface.
In the third invention, since the cross-sectional shape of the new opening frame corresponds to the exposed portion of the existing opening frame and is substantially J-shaped, the existing opening frame can be easily obscured, and it is good without trouble. A beautiful appearance can be secured.

第四の発明によれば、既存サッシ撤去後に残存する既存開口枠と、
前記既存サッシに代わって取付けられた、前記既存サッシの開口枠取付片の内法寸法より所定寸法小さな開口枠取付片の内法寸法を有する新規サッシ枠と、
前記既存サッシと前記新規サッシの開口枠取付片の内法寸法の差に対応した厚みを有し前記既存開口枠に重ね合わせて貼付されたカバー式の新規開口枠と、
を具備してなるサッシの取付け構造が提供される。
第四の発明では、既存開口枠等を撤去することなく新規サッシを取付けた構造としているので、施工が簡易であり、コストを抑えることができる。 According to the fourth invention, the existing opening frame remaining after the existing sash removal,
A new sash frame attached in place of the existing sash and having an inner dimension of the opening frame mounting piece smaller than the inner dimension of the opening frame mounting piece of the existing sash;
A cover-type new opening frame that has a thickness corresponding to the difference in the internal dimensions of the opening frame mounting pieces of the existing sash and the new sash and is affixed to the existing opening frame,
A structure for attaching a sash is provided.
In 4th invention, since it is set as the structure which attached the new sash, without removing the existing opening frame etc., construction is simple and can suppress cost.

第五の発明によれば、第四の発明において、前記新規開口枠と前記既存開口枠との間に、弾力性を有する接着層が介在されたことを特徴とする構造が提供される。
新規開口枠と既存開口枠の間に、弾力性を有する接着層を介在させたので、新規開口枠の表面には取付ビス等の露出はなく、また既存開口枠に施工に起因する寸法誤差を吸収することができるので新規開口枠の納まりが良好で、美観が担保される。 According to a fifth invention, in the fourth invention, there is provided a structure characterized in that an elastic adhesive layer is interposed between the new opening frame and the existing opening frame.
Since an elastic adhesive layer is interposed between the new opening frame and the existing opening frame, there is no exposure of mounting screws etc. on the surface of the new opening frame, and there is no dimensional error due to construction in the existing opening frame. Since it can be absorbed, the new opening frame fits well and the aesthetics are secured.

第六の発明によれば、第四又は第五の発明において、前記既存開口枠の室内側端部は、内装壁表面から突出した構成であり、前記新規開口枠は、前記既存開口枠の露出面を覆う略Ｊ字状断面を有することを特徴とするサッシの交換構造が提供される。
第六の発明では、新規開口枠の断面形状を既存開口枠の露出部分に対応させて略Ｊ字状としたので、容易に既存開口枠を覆い隠すことができ、手間をかけずに良好な美観を確保することができる。 According to a sixth invention, in the fourth or fifth invention, the indoor side end portion of the existing opening frame protrudes from the interior wall surface, and the new opening frame is an exposure of the existing opening frame. A sash replacement structure characterized by having a substantially J-shaped cross section covering the surface is provided.
In the sixth invention, since the cross-sectional shape of the new opening frame is made substantially J-shaped corresponding to the exposed portion of the existing opening frame, the existing opening frame can be easily obscured, and it is good without taking time and effort. A beautiful appearance can be secured.

本発明に係るサッシ交換方法及びサッシ構造によれば、開口枠、内装壁、木下地等を撤去しないで新規サッシを取付けていくので、良好な美観を確保しながらも、施工が簡易であり、コストを抑えることができる。   According to the sash replacement method and the sash structure according to the present invention, since the new sash is attached without removing the opening frame, the interior wall, the wood base, etc., the construction is simple while ensuring a good aesthetic, Cost can be reduced.

本発明に係るサッシ交換方法は、如何なる用途の建物に設備されたサッシに対してでも実施されうるが、通常は住宅に設備されたサッシについて、該住宅の改築等の際に実施される。そのような住宅の建築様式についても任意であるが、より好ましくは、鉄骨を組み合わせて構築される鉄骨造の架構と、該架構に取付けられる軽量気泡コンクリートパネル（以下、ＡＬＣパネルという）等からなる外壁構造を備えた工業化住宅が対象とされ、例えば外壁に開口部が形成され、その開口部にサッシが取付けられている。本発明に係るサッシ交換方法は、かかる開口部に設備された既存サッシを新規サッシに簡便に交換するのに適している。
以下、図面を参照して、本発明のサッシ交換方法に係る好ましい実施形態を説明する。 The sash replacement method according to the present invention can be carried out for a sash installed in a building of any use, but is usually carried out for a sash installed in a house when the house is remodeled. The construction style of such a house is also arbitrary, but more preferably, a steel frame constructed by combining steel frames, a lightweight cellular concrete panel (hereinafter referred to as an ALC panel) attached to the frame, and the like. An industrialized house having an outer wall structure is an object. For example, an opening is formed in the outer wall, and a sash is attached to the opening. The sash exchanging method according to the present invention is suitable for simply exchanging an existing sash provided in the opening with a new sash.
Hereinafter, a preferred embodiment according to a sash exchanging method of the present invention will be described with reference to the drawings.

図１〜２は、戸建住宅の外壁の開口部に既存サッシが取付けられている状態を示すもので、図１は縦断面図、図２は平断面図である。外壁１０は、長尺のＡＬＣパネルが複数並列状に並べて形成されてなり、布基礎上に設置された梁等の架構に自重受け金具や稲妻プレート等の金物を介して支持され、窓が形成される部分にはその上下に短尺のＡＬＣパネルが並べられて正面視矩形の開口部１１が画成されている。   1 and 2 show a state in which an existing sash is attached to an opening of an outer wall of a detached house. FIG. 1 is a longitudinal sectional view and FIG. 2 is a plan sectional view. The outer wall 10 is formed by arranging a plurality of long ALC panels in parallel, and is supported on a frame such as a beam installed on a cloth foundation via a metal fitting such as a weight holder or a lightning plate, thereby forming a window. A short ALC panel is arranged on the upper and lower sides of the portion to be formed, and a rectangular opening 11 is defined.

すなわち、開口部１１とされる外壁部分には、開口部１１の左右幅に相当する一定間隔を左右方向に保ってアングル形鋼からなる竪枠１２（一方のみを図示）が設けられている。図示は省略するが、竪枠１２の下端は布基礎まで延び、その下端間に連結された横桟が布基礎上の受鋼材上にモルタル、ボルト等によって固定される一方、竪枠１２の上端は、Ｈ型鋼からなる梁鉄骨近傍まで延び、その上端間に連結された横桟が梁鉄骨に沿設された受鋼材にボルト等によって固定されている。   That is, the outer wall portion which is the opening 11 is provided with a flange frame 12 (only one of which is shown) made of angle-shaped steel while maintaining a constant interval corresponding to the left-right width of the opening 11 in the left-right direction. Although illustration is omitted, the lower end of the eaves frame 12 extends to the cloth foundation, and a horizontal rail connected between the lower ends is fixed on the steel receiving material on the cloth foundation by mortar, bolts, etc. Is extended to the vicinity of the beam steel frame made of H-shaped steel, and a horizontal beam connected between the upper ends thereof is fixed to a steel receiving material provided along the beam steel frame by bolts or the like.

また、竪枠１２の上下方向の間には、鋼材を成形してなる上フレーム１３ａと下フレーム１３ｂが、開口部１１の上下幅に相当する一定間隔を上下方向に保ち、各両端を竪枠１２に固定されて連結されている。そして、開口部１１の下側の短尺ＡＬＣパネルは、下端が布基礎側の横桟上に載置され上端が下フレーム１３ｂと取付片１４によって固定される一方、開口部１１の上側の短尺ＡＬＣパネルは、下端が上フレーム１３ａに保持され、上端が梁側の横桟と受鋼材に取り付けられた取付片（不図示）によって挟持されて固定されている。
また、竪枠１２の上フレーム１３ａと下フレーム１３ｂの間には、左右の側フレーム１３ｃが設けられ、該左右の側フレーム１３ｃと上下フレーム１３ａ、１３ｂが相互に連結されて、開口部１１に設置されたフレーム１３となっている。 Further, between the vertical direction of the collar frame 12, an upper frame 13a and a lower frame 13b formed by forming a steel material maintain a certain distance corresponding to the vertical width of the opening 11 in the vertical direction, and both ends are arranged on the collar frame. 12 is fixed and connected. The lower ALC panel on the lower side of the opening 11 is placed on the cross rail on the fabric base side and the upper end is fixed by the lower frame 13b and the mounting piece 14, while the short ALC on the upper side of the opening 11 is fixed. The lower end of the panel is held by the upper frame 13a, and the upper end of the panel is clamped and fixed by an attachment piece (not shown) attached to the cross beam on the beam side and the steel receiving material.
In addition, left and right side frames 13c are provided between the upper frame 13a and the lower frame 13b of the collar frame 12, and the left and right side frames 13c and the upper and lower frames 13a and 13b are connected to each other to form the opening 11. It is an installed frame 13.

サッシ（既存サッシ）１５は、通常はアルミ製であり、上サッシ枠１５ａと、下サッシ枠１５ｂと、該上下サッシ枠１５ａ、１５ｂに連設された左右の側サッシ枠１５ｃからなり、各サッシ枠１５ａ、１５ｂ、１５ｃの外縁側（開口部と反対側）が各フレーム１３ａ、１３ｂ、１３ｃの内縁側（開口部側）に固定されている。そして、サッシ１５に、サッシ開閉窓本体１６が摺動可能に取付けられている。   The sash (existing sash) 15 is usually made of aluminum and includes an upper sash frame 15a, a lower sash frame 15b, and left and right side sash frames 15c connected to the upper and lower sash frames 15a and 15b. The outer edge sides (opposite sides of the openings) of the frames 15a, 15b, and 15c are fixed to the inner edge sides (opening sides) of the frames 13a, 13b, and 13c. A sash opening / closing window body 16 is slidably attached to the sash 15.

また、開口部１１の上記フレーム１３よりも室内側にずれた位置には、上枠１７ａと、下枠１７ｂと、該上下枠１７ａ、１７ｂに連結された左右の側枠１７ｃからなり開口部１１及びフレーム１３よりも小さい枠体からなる開口枠（既存開口枠）１７が配設されている。既存開口枠１７は、ロ字状に組み立てたのちに室内側に突出したサッシの開口枠取付片１８にビス止めされて固定されている。
また、既存開口枠１７の室内側端部には、壁面に沿って配設される内装壁１９が取付けられている。なお、図中、２０は柱、２１はシーリング材である。 The opening 11 is located at a position shifted from the frame 13 to the indoor side, and includes an upper frame 17a, a lower frame 17b, and left and right side frames 17c connected to the upper and lower frames 17a and 17b. In addition, an opening frame (existing opening frame) 17 made of a frame smaller than the frame 13 is disposed. The existing opening frame 17 is fixed to a sash opening frame mounting piece 18 that is projected to the indoor side after being assembled into a square shape by screws.
Further, an interior wall 19 disposed along the wall surface is attached to the indoor side end of the existing opening frame 17. In the figure, 20 is a column and 21 is a sealing material.

図１〜２に示したサッシ構造において、既存サッシ１５を新規サッシ２２に交換するための本発明の方法は、
（ａ）既存開口枠１７と既存サッシ周囲の外壁構造を残存させたまま既存サッシ１５を撤去する工程と、
（ｂ）既存サッシ１４に比べ開口枠取付片の内法寸法が小さな新規サッシ２２を準備する工程と、
（ｃ）既存サッシ１４と新規サッシ２２の開口枠取付片の内法寸法の差に対応した厚みを有するカバー式の新規開口枠２３を既存開口枠１７に重ね合わせて貼付する工程と、
（ｄ）新規サッシ２２を外壁構造であるフレーム１３に取付ける工程
を含む。以下、各工程を詳細に説明する。 In the sash structure shown in FIGS. 1 and 2, the method of the present invention for exchanging the existing sash 15 with a new sash 22 is as follows.
(A) removing the existing sash 15 while leaving the existing opening frame 17 and the outer wall structure around the existing sash;
(B) preparing a new sash 22 having a smaller inner dimension of the opening frame mounting piece than the existing sash 14;
(C) a step of attaching a cover-type new opening frame 23 having a thickness corresponding to the difference in the internal dimensions of the opening frame attaching pieces of the existing sash 14 and the new sash 22 to the existing opening frame 17;
(D) A step of attaching the new sash 22 to the frame 13 which is the outer wall structure is included. Hereinafter, each process will be described in detail.

既存サッシ撤去工程（ａ）：
この工程では、開閉窓本体１６を既存サッシ１５から取り外した後、既存サッシ１５を解体、撤去する。窓の上方部に欄間が設けられている場合は、欄間も撤去する。既存サッシ１５の解体は、サンダー、バール等を用いて各サッシ枠１５ａ、１５ｂ、１５ｃやシーリング材２１を、フレーム１３及び既存開口枠１７から引き剥がしていくことにより実施するが、フレーム１３と既存開口枠１７は、内装壁１９と共にそのまま残す。なお、開口枠取付片１８のビスを緩めることで既存サッシ１５と既存開口枠１７とは容易に分離することができる。
すなわち、従来のサッシ交換方法においては、サッシ枠１５ａ、１５ｂ、１５ｃだけでなく、フレーム１３や既存開口枠１７も撤去し、場合によっては、内装壁１９や更には周辺部材も解体撤去していたが、本発明の方法では、サッシ枠１５ａ、１５ｂ、１５ｃをシーリング材２１と共に撤去解体するだけである。
図３〜４は、既存サッシ１５を新規サッシ２２に交換した後の状態を示すもので、図３は縦断面図、図４は平断面図であるが、フレーム１３、既存開口枠１７、内装壁１９等は、サッシ交換前のものがそのまま残されている。 Existing sash removal process (a):
In this step, after the opening / closing window main body 16 is removed from the existing sash 15, the existing sash 15 is disassembled and removed. If a space is provided in the upper part of the window, the space is also removed. The existing sash 15 is disassembled by peeling off the sash frames 15a, 15b, 15c and the sealing material 21 from the frame 13 and the existing opening frame 17 using a sander, a bar, or the like. The opening frame 17 is left as it is together with the interior wall 19. The existing sash 15 and the existing opening frame 17 can be easily separated by loosening the screws of the opening frame mounting piece 18.
That is, in the conventional sash replacement method, not only the sash frames 15a, 15b, and 15c, but also the frame 13 and the existing opening frame 17 are removed, and in some cases, the interior wall 19 and further peripheral members are dismantled and removed. However, in the method of the present invention, the sash frames 15a, 15b, and 15c are simply removed and disassembled together with the sealing material 21.
3 to 4 show the state after the existing sash 15 is replaced with the new sash 22, FIG. 3 is a longitudinal sectional view, and FIG. 4 is a plan sectional view, but the frame 13, the existing opening frame 17, the interior The wall 19 and the like are left as they are before the sash replacement.

既存サッシ１５に代えて取付ける新規サッシ２２は、通常は既存サッシ１５よりも性能の優れたものとなり、細部の仕様が既存サッシ１５と異なると共に、既存サッシ１５に比べ開口枠取付片１８の内法寸法が小さなサッシが選択され準備される。この新規サッシ２２は、工程（ｃ）において取付けられる新規開口枠２３の寸法に合うように予め製作されている。すなわち、新規サッシ２２は、既存サッシ１５と同様に、上サッシ枠２２ａと、下サッシ枠２２ｂと、該上下サッシ枠２２ａ、２２ｂに連設された左右の側サッシ枠２２ｃからなり、フレーム１３と新規開口枠２３の間に取付けられるが、フレーム１３に取付けられる部位は、既存サッシ１５と同じ構造を有しているか又は既存サッシ１５の場合と同様にしてフレーム１３に取付け可能な構造を有しており、また枠体の幅が拡大されて、開口枠取付片２５の内法寸法が小さく製作されている。更に、その内周縁側は、新規開口枠２３の外壁側端部を端面側から被覆することができるように成形されている。 New sash preparation step (b):
The new sash 22 to be installed instead of the existing sash 15 is usually superior in performance to the existing sash 15, the detailed specifications are different from those of the existing sash 15, and the inner method of the opening frame mounting piece 18 compared to the existing sash 15. A sash having a small size is selected and prepared. The new sash 22 is manufactured in advance so as to match the size of the new opening frame 23 attached in the step (c). That is, the new sash 22 includes an upper sash frame 22a, a lower sash frame 22b, and left and right side sash frames 22c connected to the upper and lower sash frames 22a and 22b. Although it is attached between the new opening frames 23, the part attached to the frame 13 has the same structure as the existing sash 15 or a structure that can be attached to the frame 13 in the same manner as the existing sash 15. In addition, the width of the frame body is enlarged, and the inner dimension of the opening frame mounting piece 25 is made small. Furthermore, the inner peripheral edge side is shaped so that the outer wall side end of the new opening frame 23 can be covered from the end face side.

新規開口枠貼付工程（ｃ）：
この工程では、既存開口枠１７にカバー式の新規開口枠２３を重ね合わせ、その間に接着剤２６を介在させて新規開口枠２３を既存開口枠１７に貼付する。
既存開口枠１７は、上下枠１７ａ、１７ｂ及び左右の側枠１７ｃとも、横断面長方形の板状木材からなり、図１〜２から分かるように、互いに対向する内周面と、室内側の端面と、内周面とは反対側の背面を有し、背面の室内側端部より若干室外側に位置する箇所に内装壁１９が取付けられている。新規開口枠２３は、既存開口枠１７の上に被せた状態で、このような既存開口枠１７の室内側に露出している部分が全体的に被覆されるような形状に形成されている。すなわち、新規開口枠２３は、既存開口枠１７の上枠１７ａ、下枠１７ｂ、左右の側枠１７ｃに対応して、上枠部材２３ａ、下枠部材２３ｂ、左右の側枠部材２３ｃからなると共に、横断面視で略Ｊ字状の屈曲した板材からなり、既存開口枠１７の内周面に対向させられる内面部２４ａと、既存開口枠１７の室内側端面に対向させられる室内側端面部２４ｂと、既存開口枠１７の背面で室内に露出している部分に対向させられる背面部２４ｃとを有している。新規開口枠２３は、既存開口枠１７よりは若干大きな寸法で製作され、新規開口枠２３を既存開口枠１７の上に被せた状態で、既存開口枠１７と新規開口枠２３の間、つまり既存開口枠１７の内周面と新規開口枠２３の内面部２４ａとの間、既存開口枠１７の室内側端面と新規開口枠２３の室内側端面部２４ｂとの間、既存開口枠１７の背面と新規開口枠２３の背面部２４ｃとの間には、一定の間隙が生じ、また新規開口枠２３の背面部２４ｃの端面は内装壁１９に当接させられる一方、新規開口枠２３の内面部２４ａの外壁側端面は、既存開口枠１７の外壁側端面と同一面内に位置する寸法に設定されている。 New opening frame pasting step (c):
In this step, the cover type new opening frame 23 is superposed on the existing opening frame 17, and the new opening frame 23 is attached to the existing opening frame 17 with an adhesive 26 interposed therebetween.
The existing opening frame 17 is made of plate-like wood having a rectangular cross section in both the upper and lower frames 17a, 17b and the left and right side frames 17c. As can be seen from FIGS. And the interior wall 19 is attached to the location which has a back surface on the opposite side to an internal peripheral surface, and is located in a little outdoor side from the indoor side edge part of a back surface. The new opening frame 23 is formed in such a shape that the portion exposed to the indoor side of the existing opening frame 17 is entirely covered in a state of being covered on the existing opening frame 17. That is, the new opening frame 23 includes an upper frame member 23a, a lower frame member 23b, and left and right side frame members 23c corresponding to the upper frame 17a, the lower frame 17b, and the left and right side frames 17c of the existing opening frame 17. The inner surface 24a is made of a bent plate material having a substantially J-shape in cross-sectional view, and is opposed to the inner peripheral surface of the existing opening frame 17, and the indoor side end surface 24b is made to face the indoor side end surface of the existing opening frame 17. And a back surface portion 24c that is opposed to a portion exposed to the room on the back surface of the existing opening frame 17. The new opening frame 23 is manufactured to be slightly larger than the existing opening frame 17, and the new opening frame 23 is placed between the existing opening frame 17 and the new opening frame 23 in a state where the new opening frame 23 is placed on the existing opening frame 17. Between the inner peripheral surface of the opening frame 17 and the inner surface portion 24a of the new opening frame 23, between the indoor side end surface of the existing opening frame 17 and the indoor side end surface portion 24b of the new opening frame 23, and the back surface of the existing opening frame 17 A fixed gap is formed between the rear surface portion 24c of the new opening frame 23 and the end surface of the rear surface portion 24c of the new opening frame 23 is brought into contact with the interior wall 19, while the inner surface portion 24a of the new opening frame 23 is contacted. The outer wall side end surface is set to a dimension located in the same plane as the outer wall side end surface of the existing opening frame 17.

新規開口枠２３の既存開口枠１７への取付け方法は、使用する接着剤２６の種類によって異なる。すなわち、接着剤２６として流動性のある接着剤を利用する場合は、既存開口枠１７と新規開口枠２３の間に複数のスペーサ（図示せず）を介在させながら、新規開口枠２３を既存開口枠１７の上に被せる。ついで、スペーサによって形成された新規開口枠２３と既存開口枠１７の間の間隙に、適当な注入器を用いて接着剤２６を注入していく。接着剤２６の注入場所、注入方法等は任意であり、新規開口枠２３と既存開口枠１７の間の間隙に接着剤２６が満遍なく行き渡るか、もしくは新規開口枠２３が既存開口枠１７に強固に固定される程度に注入されるならば、如何なる方法を使用してもよい。通常は、既存開口枠１７の外壁側端部と新規開口枠２３の外壁側端部の間隙から、接着剤２６を注入していき、好ましくは内装壁１９の十分近傍まで接着剤２６が行き渡るように、注入圧等を調節して注入する。接着剤２６は所定時間で硬化し、新規開口枠２３と既存開口枠１７との間に、弾力性を有する接着層が形成される。   The attachment method of the new opening frame 23 to the existing opening frame 17 differs depending on the type of the adhesive 26 to be used. That is, when a fluid adhesive is used as the adhesive 26, the new opening frame 23 is opened while the plurality of spacers (not shown) are interposed between the existing opening frame 17 and the new opening frame 23. Cover the frame 17. Next, the adhesive 26 is injected into the gap between the new opening frame 23 formed by the spacer and the existing opening frame 17 using an appropriate injector. The place where the adhesive 26 is injected, the injection method, and the like are arbitrary, and the adhesive 26 is evenly distributed in the gap between the new opening frame 23 and the existing opening frame 17, or the new opening frame 23 is firmly attached to the existing opening frame 17. Any method may be used provided it is injected to a fixed extent. Normally, the adhesive 26 is injected from the gap between the outer wall side end of the existing opening frame 17 and the outer wall side end of the new opening frame 23, and preferably the adhesive 26 spreads to a sufficient vicinity of the interior wall 19. Then, the injection pressure is adjusted. The adhesive 26 is cured in a predetermined time, and an elastic adhesive layer is formed between the new opening frame 23 and the existing opening frame 17.

このような方法において使用する接着剤２６としては、特に限定するものではなく、様々な種類のものがあるが、膨張型接着剤、なかでも一液性湿気硬化型ウレタン樹脂系接着材、二液性発泡ウレタン樹脂系接着材を使用することができ、また適切な硬化時間のものを選択することができる。
また、接着剤２６の代わりに接着テープを使用することも可能であり、そのような場合は、既存開口枠１７の上の全面もしくは部分的に接着テープを貼り付けていき、その上から、新規開口枠２３を被せ、接着テープによって新規開口枠２３を既存開口枠１７に固定する。このような接着テープとしては、建築分野で常用されている任意のものを選択することができるが、例えばブチルテープを使用することができる。
また、新規開口枠２３が形成されたところで、新規開口枠２３と内装壁１９との間に不陸があれば、コークボンド等を用いて隙間を埋め、不陸を是正する。 The adhesive 26 used in such a method is not particularly limited, and there are various types of adhesives, such as an expandable adhesive, particularly a one-part moisture-curable urethane resin adhesive, a two-part adhesive. A flexible foamed urethane resin adhesive can be used, and one having an appropriate curing time can be selected.
In addition, it is also possible to use an adhesive tape instead of the adhesive 26. In such a case, the adhesive tape is pasted over the entire surface or part of the existing opening frame 17, and a new one is added from there. The opening frame 23 is covered and the new opening frame 23 is fixed to the existing opening frame 17 with an adhesive tape. As such an adhesive tape, any tape that is commonly used in the construction field can be selected. For example, a butyl tape can be used.
Further, when the new opening frame 23 is formed and there is unevenness between the new opening frame 23 and the interior wall 19, the gap is filled using coke bond or the like to correct the unevenness.

新規サッシ取付工程（ｄ）：
上記のようにして新規開口枠２３を既存開口枠１７に被せ、接着剤２６が硬化して新規開口枠２３が固定されたところで、工程（ｄ）において、新規サッシ２２を新規開口枠２３に取付ける。より詳細には、前述のように、新規サッシ２２のフレーム１３に取付けられる部位は、既存サッシ１５と同じ構造を有しているか又は既存サッシ１５の場合と同様にしてフレーム１３に取付け可能な構造を有しており、内周縁側は、新規開口枠２３の外壁側端部（既存開口枠１７と新規開口枠２３の端部）を端面側から被覆することができるように成形されている。
従って、新規サッシ２２は、ビス等の締結手段によって、左右の側サッシ枠２２ｃの外周面側を、外壁構造であるフレーム１３の左右の側フレーム１３ｃにそれぞれ締結し、上下サッシ枠２２ａ、２２ｂの開口部１１側とは反対側を上下フレーム１３ａ、１３ｂにそれぞれ締結する。
なお、上記において、新規開口枠貼付工程（ｃ）と新規サッシ取付工程（ｄ）の施工順序は、逆転させても構わない。 New sash mounting step (d):
When the new opening frame 23 is put on the existing opening frame 17 as described above and the adhesive 26 is cured and the new opening frame 23 is fixed, the new sash 22 is attached to the new opening frame 23 in the step (d). . More specifically, as described above, the portion attached to the frame 13 of the new sash 22 has the same structure as that of the existing sash 15 or can be attached to the frame 13 in the same manner as in the case of the existing sash 15. The inner peripheral edge side is formed so that the outer wall side end of the new opening frame 23 (the end of the existing opening frame 17 and the new opening frame 23) can be covered from the end surface side.
Accordingly, the new sash 22 is fastened to the left and right side frames 13c of the frame 13 which is the outer wall structure by fastening the outer peripheral surfaces of the left and right side sash frames 22c by fastening means such as screws, respectively. The side opposite to the opening 11 side is fastened to the upper and lower frames 13a and 13b.
In addition, in the above, you may reverse the construction order of a new opening frame sticking process (c) and a new sash attachment process (d).

また、前記新規サッシ取付工程が終了した後に、更に次の付帯工事がなされるが、この作業は順不同である。
（１）各サッシ枠２２ａ、２２ｂ、２２ｃの開口枠取付片２５に各既存開口枠１７ａ、１７ｂ、１７ｃと一体化された各新規開口枠２３ａ、２３ｂ、２３ｃの外壁側端部をビス等によって固定する。
（２）新規サッシ２２の取付けた後には、新たなシーリング材２１も施していく。
（３）新規サッシ２２の取付けが終わったところで、新規サッシ２２に寸法等の仕様が合致したサッシ開閉窓本体２７を摺動可能に取付ける。 In addition, after the new sash mounting process is completed, the following incidental work is performed, but this work is in no particular order.
(1) The outer wall side end of each new opening frame 23a, 23b, 23c integrated with each existing opening frame 17a, 17b, 17c is attached to the opening frame mounting piece 25 of each sash frame 22a, 22b, 22c with a screw or the like. Fix it.
(2) After the new sash 22 is attached, a new sealing material 21 is also applied.
(3) When the installation of the new sash 22 is completed, the sash opening / closing window main body 27 whose dimensions and other specifications match the new sash 22 is slidably mounted.

以上のように、本発明に係るサッシ交換方法によれば、既存サッシ１５を撤去するのみで、フレーム１３や既存開口枠１７、内装壁１９を解体せずに残すことができるので、施工工事内容が簡易で、工期を短縮でき、コストも低く抑えることができる。
また、新規開口枠２３の形成に際しては、新規開口枠２３と既存開口枠１７との間に接着剤２６を注入等して弾力性のある接着層を形成するので、接着層の変形により、既存開口枠１７の施工誤差が吸収され、既存開口枠１７と新規開口枠２３との隙間が調整される。よって、新規サッシ２２と新規開口枠２３を綺麗に納めることができる。
また、新規開口枠２３は既存開口枠１７に接着剤２６により接着固定し、新規サッシ２２以外は新規開口枠２３にビス固定しないため、美観が良好である。
更に、新規開口枠２３が既存開口枠１７を包み込む断面略Ｊ字状の形状であるため、接着層が露出しないし、部材納まりも良好である。 As described above, according to the sash replacement method according to the present invention, the frame 13, the existing opening frame 17, and the interior wall 19 can be left without being dismantled only by removing the existing sash 15. Is simple, the construction period can be shortened, and the cost can be kept low.
Further, when the new opening frame 23 is formed, an elastic adhesive layer is formed by injecting an adhesive 26 between the new opening frame 23 and the existing opening frame 17, so that the existing opening frame 23 is deformed by the deformation of the adhesive layer. The construction error of the opening frame 17 is absorbed, and the gap between the existing opening frame 17 and the new opening frame 23 is adjusted. Therefore, the new sash 22 and the new opening frame 23 can be stored neatly.
Further, since the new opening frame 23 is bonded and fixed to the existing opening frame 17 with the adhesive 26 and no screws other than the new sash 22 are fixed to the new opening frame 23, the appearance is good.
Furthermore, since the new opening frame 23 has a substantially J-shaped cross section that wraps around the existing opening frame 17, the adhesive layer is not exposed and the member fits well.

以上、本発明に係るサッシ交換方法について説明したが、本発明は、かかるサッシ交換方法によって新規サッシに交換されたサッシ交換構造にも関する。
すなわち、本発明の更なる好ましい実施形態は、図３〜４に示されるサッシ構造である。該サッシ構造は、既存サッシ撤去後に残存する既存開口枠１７と、既存サッシ１５に代わって取付けられた、既存サッシ１５の開口枠取付片１８の内法寸法より所定寸法小さな開口枠取付片２５の内法寸法を有する新規サッシ２２と、既存サッシ１５と新規サッシ２２の開口枠取付片２５の内法寸法の差に対応した厚みを有し既存開口枠１７に重ね合わせて貼付されたカバー式の新規開口枠２３とを具備し、新規開口枠２３と既存開口枠１７の間には間隙が形成され、該間隙に接着剤２６が注入等されて接着層が介在せしめられている。
このようなサッシ交換構造は、交換工事が短納期で簡易である上に、各部材の取合いを綺麗に納めることができ、またビスや接着剤等が露出しないため、美観に優れたものとなる。 Although the sash replacement method according to the present invention has been described above, the present invention also relates to a sash replacement structure that is replaced with a new sash by the sash replacement method.
That is, a further preferred embodiment of the present invention is the sash structure shown in FIGS. The sash structure includes an existing opening frame 17 that remains after the existing sash is removed, and an opening frame mounting piece 25 that is attached in place of the existing sash 15 and that is smaller than the inner dimension of the opening frame mounting piece 18 of the existing sash 15. A new sash 22 having an internal dimension, and a cover-type cover having a thickness corresponding to the difference between the internal dimensions of the opening frame mounting pieces 25 of the existing sash 15 and the new sash 22 and superimposed on the existing opening frame 17. A new opening frame 23 is provided, and a gap is formed between the new opening frame 23 and the existing opening frame 17, and an adhesive 26 is injected into the gap to interpose an adhesive layer.
Such a sash replacement structure is excellent in aesthetics because the replacement work is simple with a short delivery time, and it is possible to cleanly fit the parts, and the screws and adhesives are not exposed. .

なお、本発明に係るサッシ交換方法及び構造は、上記実施形態において説明した住宅構造や窓部構造に適用が限定されるものではなく、既存開口枠やフレームなどを残しながら新規サッシを取付けることができる構造である限り、他の構造に広く適用可能であることは言うまでもない。   The sash replacement method and structure according to the present invention are not limited to the housing structure and window structure described in the above embodiment, and a new sash may be attached while leaving an existing opening frame or frame. Needless to say, the present invention can be widely applied to other structures as long as the structure is possible.
