Abstract

PROBLEM TO BE SOLVED: To provide an attachment which, when a modification window is installed with the nearly entire part of a gap between an existing window frame and a newly installed window frame being filled with form hardened body, can temporarily fix the newly installed window frame to the existing window frame with great appearance and good efficiency, and also to provide an attachment which, when a window is newly installed with the nearly entire part of a gap between a wall part and the newly installed window frame being filled with form hardened body, can form a caulking groove with an appropriate depth between a peripheral part on the outdoor side of the newly installed window frame and an opening part in order to prevent intrusion of rain water.SOLUTION: An attachment in the present invention comprises: an engaging part having a substantially lying-U-shaped cross section, which has an engaging groove capable of engaging with an outdoor-side protrusion which substantially perpendicularly protrudes in the outer peripheral direction from an outdoor-side peripheral part of a window frame and bends to the indoor side forming a substantially L-shaped cross section; and a shield part having a substantially straight-line cross section, which protrudes substantially perpendicularly from a substantial tip end of one of the opposing bottom parts of the engaging part having the substantially lying-U-shaped cross section to a direction opposite to another one of the bottom parts.

Description

本発明は、既設窓枠と新設窓枠との間の空間部分、或いは、躯体と新設窓枠との間の空間部分の略全体に発泡硬化体を充填して、止水性、気密性、断熱性、遮音性、耐風圧性、耐震性、免震性、又は、制振性に優れた窓構造体（改装窓を含む）を製造する際に用いられるアタッチメント及び抑え部材に関する。   The present invention fills the foamed hardened body into the entire space part between the existing window frame and the new window frame, or the entire space part between the housing and the new window frame, to provide water-stop, air-tightness and heat insulation. The present invention relates to an attachment and a restraining member used when manufacturing a window structure (including a refurbished window) excellent in performance, sound insulation, wind pressure resistance, earthquake resistance, seismic isolation, or vibration control.

老朽化した窓をリフォームする場合、既設窓枠を撤去せずに、既設窓枠を基礎にしてその上から新設窓枠を取り付ける、いわゆる「かぶせ工法」が一般的である。この工法は、既設窓枠を取り外す必要が無いため、外壁等を壊す必要が無く、また足場が不要、工事音が少ない、工期が短い、粉塵・廃棄物が出ない、など様々な利点があり、窓を改装する方法として非常に有用である。   When renovating an aging window, a so-called “covering method” is generally used in which a new window frame is attached on top of the existing window frame without removing the existing window frame. This method has various advantages such as no need to remove the existing window frame, no need to break the outer wall, etc., no need for scaffolding, less construction sound, short construction period, no dust and waste. Very useful as a way to refurbish windows.

かぶせ工法において、新設窓枠を既設窓枠に取り付けるには、既設窓枠に新設窓枠を、介装部材を介して溶接又はビス止め等により取り付ける方法が一般的であるが、既設窓枠と新設窓枠との間に隙間が生じるため、この隙間部分を塞ぐことが必要である。例えば、この空間を塞ぐため、新設窓枠の室外側外周部に外部アタッチメントを備えることで、新設窓枠と既設窓枠との間に形成される空間を塞ぐことが開示されている（例えば、特許文献１参照）。   In the covering method, in order to attach the new window frame to the existing window frame, it is common to attach the new window frame to the existing window frame by welding or screwing via an interposition member. Since a gap is generated between the new window frame, it is necessary to close the gap. For example, in order to close this space, it is disclosed that an external attachment is provided on the outer periphery of the new window frame to close the space formed between the new window frame and the existing window frame (for example, Patent Document 1).

しかし、窓の改装が必要な場合というのは、そもそも窓枠の周りの柱や梁などの躯体に、歪みや撓み、傾きなどの不具合が生じている場合が多く、この不具合が生じた状態のまま新設窓枠を取り付けても、既設窓枠との間に生じる空間が四辺で一定ではなく、例えば、窓枠の上枠が水平でない場合などが挙げられるが、窓枠のサイズが大きければ大きいほど、このような不具合は大きく生じているのが通常である。このような躯体の歪みや撓み、傾きは、上下方向、左右方向にだけ生じるのではなく、前後方向にも生じることがあり、３次元的に生じる。また、このような躯体の不具合は、全て一様ではなく個別に異なるものである。   However, when a window needs to be refurbished, there are many cases in which there are problems such as distortion, flexure, and tilt in the frame such as pillars and beams around the window frame. Even if the new window frame is attached as it is, the space generated between the existing window frame is not constant on all four sides, and for example, the upper frame of the window frame is not horizontal. In general, such a problem usually occurs greatly. Such distortion, deflection, and inclination of the housing do not only occur in the vertical direction and the horizontal direction, but may also occur in the front-rear direction and occur three-dimensionally. Moreover, all the defects of such a case are not uniform and differ individually.

そのため、窓の改装は、個別に異なる躯体に合わせて行わなければならないため効率が悪く、一度窓枠を取り付けた後に傾き等が発見されても、後から補正することができない。したがって、外部アタッチメントにより既設窓枠と新設窓枠との間の隙間部分を塞ぐ場合においても、現場で特別に加工を施す必要が生ずるなど熟練技術を要し、さらに、新設窓枠は、メーカーによって構造が異なる汎用性の無い商品であるため、施工には専門知識を要する。そのため、かぶせ工法による窓の改装には、高度な専門知識と技能を有する職人が必要であり、人手不足や施工が高コストになり易いという問題があった。   Therefore, the refurbishment of the window has to be performed individually for different housings, so that the efficiency is low, and even if an inclination or the like is found after the window frame is once attached, it cannot be corrected later. Therefore, even when the gap between the existing window frame and the new window frame is blocked by an external attachment, skill is required such that special processing is required on site, and the new window frame is determined by the manufacturer. Since it is a non-generic product with a different structure, it requires specialized knowledge for construction. For this reason, refurbishment of windows by the cover construction method requires craftsmen with advanced expertise and skills, and there is a problem that labor shortages and construction are likely to be expensive.

また、いかに腕の良い職人により施工されたとしても、既設窓枠と新設窓枠との間の空間部分を完全に塞ぐことは困難であり、地震などによる水平応力が働いた場合、既設窓枠と新設窓枠との間の空間部分に変位が生じ、既設窓枠の変形が新設窓枠に直接作用することになり、ガラスが破壊しやすくなるといった問題が発生する。   In addition, even if it is constructed by skilled craftsmen, it is difficult to completely block the space between the existing window frame and the new window frame. A displacement occurs in the space between the new window frame and the existing window frame, and the deformation of the existing window frame directly acts on the new window frame, which causes a problem that the glass is easily broken.

また、既設窓枠と新設窓枠との間の空間部分には、室内外の温度差による結露により水滴が生じ、また止水処理に用いたコーキングの劣化によって雨水が空間部分に入り込むことがあり、これらがサビやカビの温床になったり、窓枠を腐食させて窓枠の寿命を短くしたり、さらには、壁の内部にまで浸水して壁面にヒビ割れを生じさせる要因にもなる。特に、溶接した部分は、ペイント補修を行っても、空間部分の水分によってサビが生じることが多い。また、窓の開口部が大きいほど窓には強い風圧がかかるため、風圧性能が弱ければ窓が撓んで、カバー部分が損傷し、損傷した箇所から雨風が入り込むなどの問題が発生する。   In addition, water droplets may form in the space between the existing window frame and the new window frame due to dew condensation due to temperature differences between the inside and outside of the room, and rainwater may enter the space due to deterioration of coking used for water stop treatment. These become hotbeds of rust and mold, corrode the window frame to shorten the life of the window frame, and further cause water to enter the inside of the wall and cause cracks on the wall surface. In particular, the welded portion is often rusted by moisture in the space portion even if the paint is repaired. In addition, the larger the window opening, the stronger the wind pressure is applied to the window. Therefore, if the wind pressure performance is weak, the window bends, the cover part is damaged, and rain wind enters from the damaged part.

このような中、躯体と窓枠の間隙に発泡ポリウレタンを充填し、さらにカバー部分の内面に発泡ポリウレタンを吹き付ける躯体の改修方法が開示されている（例えば、特許文献２参照）。しかし、この方法によっても、既設窓枠と新設窓枠との間に空間部分は残っているため、結露の発生を完全に防止できるものではなく、耐震性も十分ではなく、また、新設窓枠の取り付けを個別に異なる躯体に合わせて行わなければならないといった、施工の困難性を解決することはできない。   Under such circumstances, there has been disclosed a method for repairing a casing in which the gap between the casing and the window frame is filled with foamed polyurethane and the foamed polyurethane is sprayed onto the inner surface of the cover portion (see, for example, Patent Document 2). However, even with this method, since the space remains between the existing window frame and the new window frame, it is not possible to completely prevent the occurrence of condensation, and the earthquake resistance is not sufficient. However, it is not possible to solve the difficulty of construction, such as having to perform installation for each different housing.

このような問題を解決するため、既設窓枠を取り外すことなく新設窓枠を取り付けた改装窓において、既設窓枠と新設窓枠との間の空間部分の略全体に発泡硬化体を充填した改装窓が開示されている（例えば、特許文献３参照）。この工法によれば、止水性、気密性、断熱性、遮音性、耐風圧性、耐震性、免震性、又は、制振性に優れた改装窓を得ることができる。この際、既設窓枠に新設窓枠を仮止めするためにフラットバーを用いるが、既設窓枠や新設窓枠に穴開けや溶接等の加工を施す必要があった。   In order to solve such a problem, in a refurbished window in which a new window frame is attached without removing the existing window frame, the refurbishment in which the entire space portion between the existing window frame and the new window frame is filled with a foamed hardened body. A window is disclosed (for example, see Patent Document 3). According to this construction method, it is possible to obtain a refurbished window excellent in water-stopping, airtightness, heat insulation, sound insulation, wind pressure resistance, earthquake resistance, seismic isolation, or vibration control. At this time, a flat bar is used to temporarily fix the new window frame to the existing window frame, but it has been necessary to drill or weld the existing window frame or the new window frame.

ところで、上述のように改装窓を取り付ける場合だけでなく、建物の開口部に新しい窓を取り付ける場合にも、窓構造体の止水性、気密性、断熱性、遮音性、耐風圧性又は耐震性等が求められる。特許文献３で開示されたように、新設する窓と、窓を設置する開口部が形成された躯体との間に生じる空間の略全体に発泡硬化体を充填することで、これらの性能を満たす窓構造体を得ることが可能である。この際、新設窓枠を躯体に固定して発泡硬化体の原料を空間部分に充填するが、新設窓枠の室外側の周縁部と壁部の隙間にできるコーキング用溝にまで発泡硬化体が浸入することがあり、確実なコーキングが行えずに、結果として新設窓枠の周縁部からの雨水の浸入等を防ぐことができないことがあった。   By the way, not only when installing a renovated window as described above, but also when installing a new window at the opening of a building, the water tightness, airtightness, heat insulation, sound insulation, wind pressure resistance or earthquake resistance of the window structure, etc. Is required. As disclosed in Patent Document 3, the foamed cured body is filled in almost the entire space generated between the newly installed window and the housing in which the opening for installing the window is formed, thereby satisfying these performances. It is possible to obtain a window structure. At this time, the new window frame is fixed to the housing, and the raw material of the foam cured body is filled into the space portion, but the foam cured body is formed into the caulking groove formed in the gap between the outer peripheral edge of the new window frame and the wall portion. Intrusion may occur and reliable coking cannot be performed, and as a result, intrusion of rainwater from the peripheral portion of the new window frame may not be prevented.

次に、本発明にかかる第一の実施の形態について説明する。図１は、第一の実施の形態にかかる改装窓の横方向の断面図である。改装窓は、窓の改装にあたって新たに設けられる窓枠である新設窓枠１と、窓の改装前に既に設けられていた窓枠である既設窓枠２と、新設窓枠１と既設窓枠２により形成される空間の略全体に充填された発泡硬化体４と、既設窓枠２が固定されたモルタルからなる壁部（図示しない）と、新設窓枠１に設置された引違い窓６と、新設窓枠１を既設窓枠２に接合するためのアタッチメント７及びＺバー９と、アタッチメント７を新設窓枠１に固定する抑え部材８と、アタッチメント７とＺバー９を固定するビス１０と、充填された発泡硬化体４が室内側から見えないようにするためのカバー３（アルミ製）から構成されている。引違い窓６は共に水平方向に開閉が可能である。   Next, a first embodiment according to the present invention will be described. FIG. 1 is a cross-sectional view in the lateral direction of a modified window according to the first embodiment. The refurbished windows are a new window frame 1 which is a window frame newly provided for window renovation, an existing window frame 2 which is a window frame already provided before the window renovation, a new window frame 1 and an existing window frame. The foamed and hardened body 4 filled in substantially the entire space formed by 2, a wall portion (not shown) made of mortar to which the existing window frame 2 is fixed, and the sliding window 6 installed in the new window frame 1 And an attachment 7 and a Z bar 9 for joining the new window frame 1 to the existing window frame 2, a holding member 8 for fixing the attachment 7 to the new window frame 1, and a screw 10 for fixing the attachment 7 and the Z bar 9. And the filled foaming hardening body 4 is comprised from the cover 3 (product made from aluminum) for making it invisible from the indoor side. Both sliding windows 6 can be opened and closed horizontally.

本発明における改装窓の施工手順としては、既設窓枠２に新設窓枠１を接合させたのち、新設窓枠１と既設窓枠２との間に生じる室外側と室内側の隙間部分のいずれか一方あるいは両方を粘着テープで塞ぎ、該粘着テープに発泡硬化体原料を注入する注入孔を穿設し、注入孔から発泡硬化体原料を注入して新設窓枠１と既設窓枠２との間の空間部分の略全体に発泡硬化体４を充填する方法があげられる。   As a construction procedure of the refurbished window in the present invention, after the new window frame 1 is joined to the existing window frame 2, any of the gap between the outdoor side and the indoor side generated between the new window frame 1 and the existing window frame 2 is selected. Either or both of them are closed with an adhesive tape, an injection hole for injecting the foamed cured material into the adhesive tape is formed, and the foamed cured material is injected from the injection hole to establish a connection between the new window frame 1 and the existing window frame 2. There is a method of filling the foamed cured body 4 over substantially the entire space portion between them.

但し、発泡硬化体原料が硬化して発泡硬化体４となることで、既設窓枠２と新設窓枠１とを強固に接着して接合強度を高めるので、既設窓枠２と新設窓枠１のアタッチメント７による接合は、発泡硬化体４が硬化するまでの間、新設窓枠１が安定した状態を維持できる強度があれば足りる。新設窓枠１を傾くことなく水平に維持できれば、アタッチメント７は、新設窓枠１に対してやや傾いた面を有していても良い。また、Ｚバー９は、３００ｍｍ〜４５０ｍｍ程度の幅を有しているため、Ｚバー９が設けられていない隙間は、透明又は半透明の粘着テープで塞ぐことで、発泡硬化体原料を注入した際の流出を防ぐことも可能となる。   However, since the foamed cured body raw material is cured to become the foamed cured body 4, the existing window frame 2 and the new window frame 1 are firmly bonded to increase the bonding strength. For the joining by the attachment 7, it is sufficient that the new window frame 1 has a strength capable of maintaining a stable state until the foamed cured body 4 is cured. If the new window frame 1 can be maintained horizontally without being tilted, the attachment 7 may have a surface slightly inclined with respect to the new window frame 1. In addition, since the Z bar 9 has a width of about 300 mm to 450 mm, the gap where the Z bar 9 is not provided is closed with a transparent or translucent adhesive tape to inject the foamed cured material. It is also possible to prevent outflow.

発泡硬化体原料の注入は粘着テープに穿設された注入孔から行われる。発泡硬化体原料を注入した後に、新設窓枠１と既設窓枠２との間に生じる室外側と室内側の隙間部分を、アルミ製のカバー３に代わり、化粧部材で塞ぐことも可能である。粘着テープは、化粧部材の取り付けに邪魔にならなければそのままでも良いし、剥がしてから化粧部材を取り付けても良い。新設窓枠１と既設窓枠２との間に生じる室外側と室内側の隙間部分のいずれか一方のみを注入孔を設けてある化粧部材で塞ぎ、他方は注入孔を設けていない化粧部材で塞ぐことも可能である。また、室外に面する既設窓枠２と新設窓枠１との隙間部分はバックアップ材をはめ込みシール等で充填しても良い。   Injection | pouring of a foaming hardening body raw material is performed from the injection hole drilled in the adhesive tape. After injecting the foamed cured material, it is possible to close the gap between the outdoor side and the indoor side generated between the new window frame 1 and the existing window frame 2 with a decorative member instead of the aluminum cover 3. . The adhesive tape may be left as it is if it does not interfere with the attachment of the decorative member, or the decorative member may be attached after peeling off. Only one of the outdoor and indoor gaps between the new window frame 1 and the existing window frame 2 is closed with a decorative member provided with an injection hole, and the other is a decorative member provided with no injection hole. It can also be closed. Further, a gap between the existing window frame 2 and the new window frame 1 facing the outside may be filled with a backup material by inserting a backup material.

本発明の改装窓は、既設窓枠２と新設窓枠１との間に生じる、窓枠の四辺の室内外に通じる隙間部分が（図示しない）化粧部材で塞がれていてもよい。新設窓枠１は、既設窓枠２の内周側に取り付けるものであるから、既設窓枠２よりも小さいものを使用するが、既設窓枠２に対して新設窓枠１が隙間無く収まるということはなく、どうしても既設窓枠２と新設窓枠１との間に若干の隙間部分が生じてしまうし、既設窓枠２自体が傾いていたり、歪んでいれば、隙間部分は必ず生じるものである。このように、既設窓枠２と新設窓枠１との間に隙間部分があることで、窓枠の室内外から、既設窓枠２と新設窓枠１との空間部分に充填した発泡硬化体４が見えてしまう。そこで、隙間部分を化粧部材により塞ぐことで、発泡硬化体４が窓枠の室内外から見えないようにすることができる。   In the refurbished window of the present invention, gap portions that are formed between the existing window frame 2 and the new window frame 1 and that communicate with the interior and exterior of the four sides of the window frame may be closed with a decorative member (not shown). Since the new window frame 1 is attached to the inner peripheral side of the existing window frame 2, a smaller one than the existing window frame 2 is used, but the new window frame 1 fits in the existing window frame 2 without a gap. However, there will be a slight gap between the existing window frame 2 and the new window frame 1, and if the existing window frame 2 itself is tilted or distorted, the gap will always be generated. is there. As described above, since there is a gap between the existing window frame 2 and the new window frame 1, the foamed cured body filled in the space portion between the existing window frame 2 and the new window frame 1 from the inside and outside of the window frame. 4 will be visible. Therefore, the foamed cured body 4 can be prevented from being seen from inside and outside the window frame by closing the gap portion with the decorative member.

化粧部材は、例えば、平板状、又は断面がＬ字形状のアルミ製のものが適しているが、プラスチック製、木製、紙製等の材質でも良い。また、美観向上の観点から、化粧部材の上に、さらに木目が印刷されたプラスチック板や紙片、合板などを貼り付けても良い。化粧部材は、隙間部分が生じる窓枠の四辺に取り付けられ、粘着性の両面テープや接着剤などで窓枠に接着されても良いし、ビス止めされても良い。なお、改装窓の止水性、気密性、断熱性、遮音性は、既設窓枠２と新設窓枠１の間の空間部分の略全体を発泡硬化体４で埋めることで十分得られるので、化粧部材は、単に美観上の問題として隙間部分を隠すだけで良く、強固に取り付ける必要はない。   As the decorative member, for example, a flat plate or an L-shaped aluminum member is suitable, but a plastic member, a wooden member, a paper member, or the like may be used. Further, from the viewpoint of improving aesthetic appearance, a plastic plate, paper piece, plywood, or the like on which a grain is further printed may be pasted on the decorative member. The decorative member is attached to the four sides of the window frame where the gap portion is generated, and may be adhered to the window frame with an adhesive double-sided tape or an adhesive, or may be screwed. The waterproofing, airtightness, heat insulation, and sound insulation of the refurbished window can be obtained sufficiently by filling almost the entire space between the existing window frame 2 and the new window frame 1 with the foamed cured body 4. The member only needs to hide the gap as an aesthetic problem, and does not need to be firmly attached.

隙間部分は、室内側と室外側の両方に生じるが、化粧部材は両方とも同じ部材を用いる必要は無い。例えば、室内側は、常に居住者から見える部分であるため、美観を損なわないように配慮する必要があるが、室外側は、美観よりも機能を重視する必要があるから、雨風に強い部材を用いる必要がある。   The gap portion is generated on both the indoor side and the outdoor side, but it is not necessary to use the same member for both decorative members. For example, the indoor side is a part that is always visible to the resident, so it is necessary to consider so as not to impair the aesthetics. It is necessary to use it.

化粧部材は、発泡硬化体４を充填した後に取り付けても良いし、発泡硬化体４を充填する前に取り付けても良い。発泡硬化体４を充填する前に化粧部材を取り付けた場合は、化粧部材によって発泡硬化体４が溢れ出ないようにすることができる。それとは逆に、発泡硬化体４を充填した後に化粧部材を取り付ける場合は、発泡ポリウレタンが充填され、溢れ出た場合には削ぎ落としてから取り付けることになる。   The decorative member may be attached after filling the foam cured body 4 or may be attached before filling the foam cured body 4. When the decorative member is attached before filling the foam cured body 4, the foam cured body 4 can be prevented from overflowing by the decorative member. On the contrary, when the decorative member is attached after the foamed cured body 4 is filled, the foamed polyurethane is filled, and when it overflows, it is attached after being scraped off.

化粧部材を取り付ける際には、バックアップ材及びシーリング材などの充填材によってコーキングを施しても良いし、これらのコーキングを施さないで、そのまま化粧部材を取り付けるだけでも良い。これは、発泡硬化体がコーキングの役目を果たすためである。但し、室外側の雨風に曝される場所については、化粧部材の剥がれや汚れを防ぐために、コーキングを施しておくことが好ましい。   When the decorative member is attached, caulking may be performed with a filler such as a backup material and a sealing material, or the decorative member may be attached as it is without being subjected to such caulking. This is because the foamed cured product plays a role of coking. However, it is preferable to caulk the place exposed to rain and wind outside the room in order to prevent the decorative member from peeling off and soiling.

既設窓枠２と新設窓枠１との間の空間部分の略全体に発泡硬化体４を充填する前に化粧部材を取り付ける場合は、化粧部材の任意の箇所に、発泡硬化体原料を空間内に注入する注入孔が設けられていても良い。発泡硬化体４を充填した後に化粧部材を取り付ける場合、発泡硬化体４は既に空間内部に充填されているため、化粧部材を取り付けた後に発泡硬化体４を充填する必要は無いが、発泡硬化体４を充填する前に化粧部材を取り付けた場合は、発泡硬化体原料を空間内部に充填する隙間を確保しておくか、化粧部材自体に発泡硬化体原料を注入する注入孔を設けておく必要がある。   When the decorative member is attached before filling the foamed cured body 4 over substantially the entire space between the existing window frame 2 and the new window frame 1, the foamed cured material raw material is placed in any space of the decorative member. There may be provided an injection hole for injecting. When the decorative member is attached after filling the foam cured body 4, the foam cured body 4 is already filled in the space, and therefore it is not necessary to fill the foam cured body 4 after attaching the decorative member. When the decorative member is attached before filling 4, it is necessary to secure a gap for filling the foamed cured material into the space or to provide an injection hole for injecting the foamed cured material into the decorative member itself. There is.

化粧部材の任意の箇所に発泡硬化体原料を注入する注入孔を設ける場合、空間内部で発泡した発泡硬化体４は、注入孔から溢れ出ることになるが、隙間部分全体から発泡硬化体４が溢れ出る場合と比べ、溢れ出る量を極めて少なくできるだけでなく、溢れ出た発泡硬化体４を削り落とす作業が大幅に減ることになり、発泡硬化体４の充填量の節約にもつながる。   In the case where an injection hole for injecting the foamed cured product material is provided at an arbitrary position of the decorative member, the foamed cured product 4 foamed inside the space overflows from the injection hole, but the foamed cured product 4 extends from the entire gap portion. Compared with the case of overflowing, not only can the amount of overflowing be extremely small, but also the work of scraping off the overflowing foamed cured body 4 will be greatly reduced, leading to saving of the filling amount of the foamed cured body 4.

次に、新設窓枠１が既設窓枠２にどのように固定されているかについて、より詳しく説明をする。図２（ａ）は、新設窓枠１に取り付けられたアタッチメント７と抑え部材８を表す図の一例である。また、図２（ｂ）は、改装窓の窓枠の上枠部分を表す図の一例である。アタッチメント７は、係合溝７ｃを有する略断面コの字状の係合部７ｂと、係合部７ｂの相対する平行な略断面直線状の底辺部（コの字の上下の平行な横線に相当する部分）のうちの一方（以下、下辺部７ｆという）の略先端から、下辺部７ｆから見て他方の底辺部（以下、上辺部７ｄという）が存在する方向とは反対方向へ、略垂直に突出した略断面直線状の遮蔽部７ａと、下辺部７ｆにおいて遮蔽部７ａよりも室内側の位置から、下辺部７ｆから見て上辺部７ｄが存在する方向とは反対方向へ略垂直に突出した略断面直線状の固定部７ｇとから構成されている。すなわち、遮蔽部７ａと固定部７ｇは下辺部７ｆから同じ方向へ突出している。固定部７ｇは、遮蔽部７ａよりも室内側に位置しており、通常、係合部７ｂのコの字の縦線に相当する断面直線状の連結部７ｅと同一直線状になるように形成されている。遮蔽部７ａの下辺部７ｆからの長さは、固定部７ｇの約２倍の長さを有する。なお、アタッチメント７の素材としては特に限定されないが、新規窓枠１の室外側の表面と同じ素材であることが好ましく、例えば、アルミなどが好ましい。   Next, how the new window frame 1 is fixed to the existing window frame 2 will be described in more detail. FIG. 2A is an example of a diagram illustrating the attachment 7 and the holding member 8 attached to the new window frame 1. Moreover, FIG.2 (b) is an example of the figure showing the upper frame part of the window frame of a refurbished window. The attachment 7 includes an engagement portion 7b having a substantially U-shaped cross section having an engagement groove 7c, and a parallel bottom surface portion of the engagement portion 7b that is parallel to the substantially parallel cross section (in parallel horizontal lines above and below the U shape). From the approximate tip of one of the corresponding portions (hereinafter referred to as the lower side portion 7f), in a direction opposite to the direction in which the other bottom side portion (hereinafter referred to as the upper side portion 7d) exists as viewed from the lower side portion 7f, The shielding part 7a having a substantially straight section protruding vertically and the position of the lower side 7f from the indoor side of the shielding part 7a is substantially perpendicular to the direction opposite to the direction in which the upper side 7d exists when viewed from the lower side 7f. The fixed part 7g of the substantially cross-sectional linear form protruded is comprised. That is, the shielding part 7a and the fixing part 7g protrude in the same direction from the lower side part 7f. The fixing part 7g is located on the indoor side of the shielding part 7a, and is usually formed to be collinear with the connecting part 7e having a linear cross section corresponding to the U-shaped vertical line of the engaging part 7b. Has been. The length from the lower side part 7f of the shielding part 7a is about twice as long as the fixed part 7g. In addition, although it does not specifically limit as a raw material of the attachment 7, It is preferable that it is the same material as the surface of the outdoor side of the new window frame 1, for example, aluminum etc. are preferable.

新設窓枠１には、室外側周縁部から外周方向へ略垂直に突出し、室内側へ屈曲した略断面Ｌ字状の室外側突起部１１が設けられている。室外側突起部１１のＬ字状の室内側へ屈曲した先端部１１ａは、アタッチメント７の係合溝７ｃと係合可能である。例えば、先端部１１ａの幅が７ｍｍ、厚さが１．６ｍｍである場合は、係合溝７ｃの遮蔽部７ａからの深さは７ｍｍであり、溝の幅１．６ｍｍである。先端部１１ａと係合溝７ｃが係合すると、遮蔽部７ａの室外側の面は、新規窓枠１の室外側の平面と同一平面を形成するため、室外から改装窓を見たときであっても見栄えが良くなる。   The new window frame 1 is provided with an outdoor protrusion 11 having a substantially L-shaped cross section that protrudes substantially perpendicularly from the outer peripheral edge to the outer peripheral direction and is bent toward the indoor side. The distal end portion 11 a bent toward the L-shaped indoor side of the outdoor projection 11 can be engaged with the engagement groove 7 c of the attachment 7. For example, when the tip portion 11a has a width of 7 mm and a thickness of 1.6 mm, the depth of the engaging groove 7c from the shielding portion 7a is 7 mm, and the groove width is 1.6 mm. When the distal end portion 11a and the engaging groove 7c are engaged, the outdoor side surface of the shielding portion 7a forms the same plane as the outdoor side plane of the new window frame 1. Therefore, when the modified window is viewed from the outside. But it looks better.

固定部７ｇは、Ｚバー９のＺの文字の横線に相当する部分（上辺部）と重ねあわされ、ビス１０によりビス止めされる。なお、固定部７ｇとＺバー９の上辺部には、ビス止め用の孔が設けられている。一方、Ｚバー９におけるＺの文字のもう一方の横線に相当する部分（下辺部）と遮蔽部７ａとの間に、既設窓枠２の室外側周縁部から窓の内周方向へ向かって突出した略断面直線状の室外側表面部２ａを挟みこむことで、既設窓枠２がアタッチメント７に接合される。   The fixing portion 7g is overlapped with a portion (upper side portion) corresponding to the horizontal line of the letter Z of the Z bar 9, and is screwed with a screw 10. In addition, the fixing part 7g and the upper side part of the Z bar 9 are provided with holes for screwing. On the other hand, between the part (lower side part) corresponding to the other horizontal line of the letter Z in the Z bar 9 and the shielding part 7a, it protrudes from the outdoor peripheral edge part of the existing window frame 2 toward the inner peripheral direction of the window. The existing window frame 2 is joined to the attachment 7 by sandwiching the outdoor-side surface portion 2a having a substantially straight section.

抑え部材８は、室外側突起部１１に係合溝７ｃが係合したアタッチメント７を固定する役割を果たすもので、アタッチメント７が室内側に移動することを防ぐものである。抑え部材８の素材としては合成樹脂が用いられ、例えば、塩化ビニル系樹脂、スチレン系樹脂、ポリオレフィン系樹脂を用いることが好ましい。新設窓枠１には、新設窓枠１の室内側周縁部から外周方向へ略垂直に突出し、かつ、室外側へ屈曲した略断面Ｌ字状の室内側突起部１２が設けられており、抑え部材８は、アタッチメント７と室内側突起部１２との間に嵌入可能な略断面直線状の抑え部８ａと、抑え部８ａの両端から抑え部８ａに対して略垂直に略断面直線状に立設され、且つ、該直線の抑え部８ａに平行な突起を有する係止部８ｂ、８ｃとから構成されている。   The restraining member 8 plays a role of fixing the attachment 7 with the engagement groove 7c engaged with the outdoor protrusion 11 and prevents the attachment 7 from moving to the indoor side. A synthetic resin is used as the material of the restraining member 8, and for example, a vinyl chloride resin, a styrene resin, or a polyolefin resin is preferably used. The new window frame 1 is provided with an indoor-side protruding portion 12 having a substantially L-shaped cross section that protrudes substantially perpendicularly from the indoor peripheral edge of the new window frame 1 to the outer peripheral direction and is bent outward. The member 8 has a substantially cross-section linear holding portion 8a that can be fitted between the attachment 7 and the indoor-side protruding portion 12, and a substantially cross-sectional linear shape that is substantially perpendicular to the holding portion 8a from both ends of the holding portion 8a. It is comprised from the latching | locking part 8b, 8c which is provided and has a protrusion parallel to this linear holding | suppressing part 8a.

係止部８ｂ及び８ｃが有する抑え部８ａに平行な突起は、抑え部８ａとその両端において段を形成しており、係合部７ｂのコの字の縦線に相当する断面直線状の連結部７ｅと、室内側突起部１２の先端部１２ａとの間に抑え部８ａが嵌入されると、該段が引っ掛かるため、窓枠の外周方向への抑え部材８の移動が制限されることになる。係止部８ｂ及び８ｃと、抑え部８ａにより形成される段の大きさは、係合部７ｂと先端部１２ａの大きさに合わせて、抑え部８ａが新設窓枠１の厚さ方向（室内から室外へ向かう方向）と平行になるように形成されている。   The protrusions parallel to the restraining portion 8a of the locking portions 8b and 8c form steps at the restraining portion 8a and both ends thereof, and are connected in a straight line section corresponding to the U-shaped vertical line of the engaging portion 7b. When the restraining portion 8a is inserted between the portion 7e and the distal end portion 12a of the indoor-side protruding portion 12, the step is caught, so that the movement of the restraining member 8 in the outer peripheral direction of the window frame is limited. Become. The size of the step formed by the locking portions 8b and 8c and the holding portion 8a is adjusted according to the size of the engaging portion 7b and the tip portion 12a. In the direction from the outside to the outside).

係止部８ｂ及び８ｃのそれぞれは、抑え部８ａが嵌入された場合に新設窓枠１の外周側の底面部１３と当接するように、抑え部８ａから略垂直に直線状に伸びている。このため、窓枠の内周方向への抑え部材８の移動を制限することができる。このように係止部８ｂ及び８ｃの役割により、発泡硬化体４の原料が注入された際であっても、抑え部材８の移動を防ぐことができる。   Each of the locking portions 8b and 8c extends substantially vertically from the holding portion 8a so as to come into contact with the bottom surface portion 13 on the outer peripheral side of the new window frame 1 when the holding portion 8a is fitted. For this reason, the movement of the restraining member 8 in the inner peripheral direction of the window frame can be restricted. Thus, the movement of the restraining member 8 can be prevented by the roles of the locking portions 8b and 8c even when the raw material of the foam cured body 4 is injected.

既設窓枠２は、アンカーボルト２２を用いて躯体５に固定されている。より具体的には、既設窓枠２から外周方向に突出した略断面Ｌ字状の室外側突起部の先端部２ｂ及び、同じく略断面Ｌ字状の室内側突起部の先端部２ｃを２枚の固定板２３ａ及び２３ｂで挟みこみ、これをアンカーボルト２２で固定することにより行われる。既設窓枠２の室外側周縁部と相対する躯体５との間には、コーキング２０ａが施されている。また、既設窓枠２の室内側周縁部と相対する内装部材２４との間には、コーキング２０ｂが施されている。   The existing window frame 2 is fixed to the housing 5 using anchor bolts 22. More specifically, the front end portion 2b of the outdoor-side projection portion having a substantially L-shaped cross-section projecting from the existing window frame 2 in the outer peripheral direction and the front end portion 2c of the indoor-side projection portion having a substantially L-shaped cross-section are also provided. The fixing plates 23 a and 23 b are sandwiched between the fixing plates 23 a and 23 b and fixed with the anchor bolts 22. A caulking 20a is applied between the outer peripheral edge of the existing window frame 2 and the opposite casing 5. Further, caulking 20b is applied between the indoor side peripheral portion of the existing window frame 2 and the facing interior member 24.

既設窓枠２に新設窓枠１を固定する手順としては、まず、新設窓枠１の先端部１１ａにアタッチメント７を係合させ、その後、抑え部材８をアタッチメント７と新設窓枠の先端部１２ａの間に嵌入させることで、新設窓枠１にアタッチメント７を固定させる。その後、Ｚバー９を用いてビス１０により、既設窓枠２にアタッチメント７を固定させる方法が挙げられる。また或いは、先に、Ｚバー９を用いてビス１０により、既設窓枠２にアタッチメント７を固定させ、その後、新設窓枠１の先端部１１ａにアタッチメント７を係合させ、抑え部材８をアタッチメント７と新設窓枠１の先端部１２ａの間に嵌入させても良い。これらの方法をとることで、既設窓枠２に新設窓枠１を固定する際に、特に溶接などの接合作業を行う必要なく、効率よく、改装窓を施工することが可能となる。   As a procedure for fixing the new window frame 1 to the existing window frame 2, first, the attachment 7 is engaged with the tip 11 a of the new window frame 1, and then the holding member 8 is attached to the attachment 7 and the tip 12 a of the new window frame. The attachment 7 is fixed to the new window frame 1 by being inserted between the two. Then, the method of fixing the attachment 7 to the existing window frame 2 with the screw | thread 10 using the Z bar 9 is mentioned. Alternatively, first, the attachment 7 is fixed to the existing window frame 2 with the screw 10 using the Z bar 9, and then the attachment 7 is engaged with the distal end portion 11 a of the new window frame 1 to attach the holding member 8. 7 and the front end 12a of the new window frame 1 may be fitted. By adopting these methods, when the new window frame 1 is fixed to the existing window frame 2, it is possible to construct the refurbished window efficiently without particularly performing a joining operation such as welding.

図３は、本発明の実施の形態にかかる改装窓の内観姿図の一例である。図中、実線が新設された窓を表すもので、破線は改装前に既設されていた既設窓枠２、及び、アタッチメントを固定するために用いたＺバー９ａ〜ｃを表示するものである。窓は略長方形の引き違い窓であり、木製又は金属製の窓枠が窓の四辺に設けられている。窓枠の内側に溝が形成されており、この溝に透明又は半透明のガラスが嵌めこまれている。新規窓枠１と既設窓枠２の隙間に、発泡硬化体が充填されている。図３からわかるように、アタッチメントを用いた新設窓枠１と既設窓枠２の固定は、上枠と左右枠の３点にて行われる。用いられたＺバー９の幅は新設窓枠１の縦横の長さの約３分の１である４００ｍｍ程度が好ましい。   FIG. 3 is an example of an interior view of the modified window according to the embodiment of the present invention. In the figure, the solid line represents a newly installed window, and the broken line represents the existing window frame 2 that was installed before refurbishment and the Z bars 9a to 9c used to fix the attachment. The window is a substantially rectangular sliding window, and wooden or metal window frames are provided on the four sides of the window. A groove is formed inside the window frame, and transparent or translucent glass is fitted in the groove. A foamed cured body is filled in a gap between the new window frame 1 and the existing window frame 2. As can be seen from FIG. 3, the new window frame 1 and the existing window frame 2 using the attachment are fixed at three points: the upper frame and the left and right frames. The width of the Z bar 9 used is preferably about 400 mm, which is about one third of the length and width of the new window frame 1.

次に、本発明にかかる第二の実施の形態、すなわち、躯体５に新設の窓を設置する場合について説明する。説明する。図４（ａ）は、新設窓枠１に取り付けられたアタッチメント７と抑え部材８を表す図の一例である。また、図４（ｂ）は、窓構造体の窓枠の上枠部分を表す図の一例である。躯体５に窓を設置する場合に用いるアタッチメント７は、固定部７ｇが設けられていないこと以外は、改装窓を施工する場合と同じで、遮蔽部７ａと係合部７ｂから構成される。係合部７ｂは、新設窓枠１の先端部１１ａと係合可能な係合溝７ｃを有する。遮蔽部７ａの下辺部７ｆからの長さは、所望のコーキング用溝の深さを得るために適宜定めることが可能である。また、抑え部材８は、改装窓を施工する場合と同じ形状のものが用いられる。抑え部材８を用いた新設窓枠１へのアタッチメント７の固定は、改装窓を施工する際と同様に行われる。   Next, a second embodiment according to the present invention, that is, a case where a new window is installed in the housing 5 will be described. explain. FIG. 4A is an example of a diagram illustrating the attachment 7 and the holding member 8 attached to the new window frame 1. Moreover, FIG.4 (b) is an example of the figure showing the upper-frame part of the window frame of a window structure. The attachment 7 used when installing a window on the housing 5 is the same as the case where a refurbished window is constructed except that the fixing part 7g is not provided, and is composed of a shielding part 7a and an engaging part 7b. The engaging portion 7 b has an engaging groove 7 c that can be engaged with the distal end portion 11 a of the new window frame 1. The length from the lower side portion 7f of the shielding portion 7a can be appropriately determined in order to obtain a desired depth of the caulking groove. Moreover, the thing of the same shape as the case where the control member 8 constructs a refurbished window is used. The attachment 7 is fixed to the new window frame 1 using the holding member 8 in the same manner as when the refurbished window is constructed.

新設窓枠１に抑え部材８を用いてアタッチメント７を固定した後に、新設窓枠１の躯体５への固定が行われる。新設窓枠１の躯体５への固定は、図示しないが、新設窓枠１の室外側突起部１１の先端部１１ａ及び室内側突起部１２の先端部１２ａを２枚の固定板で挟みこみ、これをアンカーボルトで固定することにより行われる。また、発泡硬化体原料の充填作業に際し、躯体５と新設窓枠１との間の空間部分に仮止め用のスペーサを、等間隔毎（例えば、３５〜４０ｃｍ毎）に挿入し、窓本体を壁に固定しても良い。発泡硬化体原料が充填された後、仮止め用のスペーサを外し、スペーサが挿入されていた部分（発泡硬化体が充填されていない部分）にも発泡硬化体原料を注入することで、接合強度に優れた窓構造体が得られる。   After fixing the attachment 7 to the new window frame 1 using the restraining member 8, the new window frame 1 is fixed to the housing 5. Although fixing the new window frame 1 to the housing 5 is not shown, the front end portion 11a of the outdoor projection 11 and the front end portion 12a of the indoor projection 12 of the new window frame 1 are sandwiched between two fixing plates, This is done by fixing with an anchor bolt. In addition, when filling the foamed cured material, a temporary fixing spacer is inserted into the space between the housing 5 and the newly installed window frame 1 at regular intervals (for example, every 35 to 40 cm). It may be fixed to the wall. After filling the foam hardened material, remove the temporary fixing spacer, and inject the foam hardened material into the part where the spacer was inserted (the part not filled with the foam hardened material). An excellent window structure can be obtained.

新設窓枠１にアタッチメント７を固定することで、アタッチメント７を用いない場合に比べ、新設窓枠１の周縁部の室外側表面と、該表面と相対する躯体５との間に形成されるコーキング用溝２１を深くすることが可能となる。コーキング用溝２１が浅くなると、新設窓枠１と躯体５との間に生じる空間に、発泡硬化体原料を室内側から充填した場合に、原料がコーキング用溝２１まで浸入し、場合によっては、コーキング用溝２１から溢れてしまい、その結果、漏れなくコーキングができない場合もある。しかし、本発明のアタッチメント７を用いることで、発泡硬化体４の原料がコーキング用溝２１まで浸入することを防ぐことができるため、漏れのない確実なコーキング２０ｃを施工することができる。なお、発泡硬化体原料を設窓枠１と躯体５との間に生じる空間に注入する際に、室内側に仮材２５を設けることで、原料の室内側への漏れを防ぐことができる。   Compared to the case where the attachment 7 is not used by fixing the attachment 7 to the new window frame 1, the caulking formed between the outdoor surface of the peripheral edge of the new window frame 1 and the housing 5 facing the surface. It becomes possible to make the groove 21 deep. When the caulking groove 21 becomes shallow, when the foamed cured material is filled from the indoor side into the space formed between the new window frame 1 and the casing 5, the raw material enters the caulking groove 21. In some cases, the caulking groove 21 overflows, and as a result, coking cannot be performed without leakage. However, by using the attachment 7 of the present invention, it is possible to prevent the raw material of the foam cured body 4 from entering the caulking groove 21, and thus it is possible to construct a reliable coking 20 c without leakage. In addition, when inject | pouring a foaming hardening body raw material into the space produced between the installation frame 1 and the housing 5, the provisional material 25 is provided in an indoor side, and the leakage to the indoor side of a raw material can be prevented.

本発明で用いられる発泡硬化体４とは、発泡ポリウレタン、発泡ポリオレフィン等の発泡性樹脂や発泡石膏等の、発泡しつつ（比較的短時間で）硬化する物質をいう。発泡ポリオレフィンとは、ポリエチレンやポリプロピレン等のポリオレフィンに発泡剤を加えて発泡させたものをいう。石膏は、高速攪拌機を用いて焼石膏と水の混合物に空気を導入することにより発泡させることができる。また、硬化に要する時間は、１０〜２０分程度である。   The foamed cured product 4 used in the present invention refers to a substance that cures while foaming (in a relatively short time), such as foamed resins such as foamed polyurethane and foamed polyolefin, and foamed gypsum. The foamed polyolefin refers to a foamed material obtained by adding a foaming agent to a polyolefin such as polyethylene or polypropylene. The gypsum can be foamed by introducing air into the mixture of calcined gypsum and water using a high speed stirrer. The time required for curing is about 10 to 20 minutes.

本発明の発泡硬化体４として発泡ポリウレタンが用いられる場合、発泡硬化体原料は２種類のポリウレタン原料と発泡剤とを含む混合物である。発泡ポリウレタンとは、ポリウレタン原料に発泡剤を加えて発泡及び硬化させたものをいい、例えば、２種類の液体ポリウレタン原料（イソシアネート及びポリオール等）と、代替フロン液化ガス等の発泡剤とを高圧容器に密封してあり、使用時にこれらを混合して空気中に放出することにより、発泡しつつ硬化する一般的な市販品を採用すればよい。発泡ポリウレタンであれば、既設窓枠２と新設窓枠１の間の空間部分といった複雑な形状であっても、空間の略全体にわたって、簡便に硬化体を充填することが可能である。なお、発泡ポリウレタン、特に一般に硬質発泡ポリウレタンと呼ばれるものは、硬化後の硬度が比較的高く、新設窓枠の接着強度が高まるため、より好ましい。   When foamed polyurethane is used as the foamed cured product 4 of the present invention, the foamed cured material is a mixture containing two types of polyurethane materials and a foaming agent. Foamed polyurethane refers to a polyurethane raw material that is foamed and cured by adding a foaming agent. For example, two types of liquid polyurethane raw materials (isocyanate, polyol, etc.) and a foaming agent such as alternative chlorofluorocarbon liquefied gas are used in a high-pressure container. What is necessary is just to employ | adopt the general commercial item which hardens | cures while foaming by mixing these at the time of use and discharge | releasing in the air at the time of use. If it is a polyurethane foam, even if it is a complicated shape such as a space portion between the existing window frame 2 and the new window frame 1, it is possible to easily fill the cured body over substantially the entire space. In addition, foamed polyurethane, particularly what is generally called rigid foamed polyurethane, is more preferable because the hardness after curing is relatively high and the adhesive strength of the new window frame is increased.

一般の市販品においては、２種類のポリウレタン原料を同一の高圧容器に充填してあり、使用時にその高圧容器内で混合するもの（１液性）と、２種類のポリウレタン原料を別個の高圧容器に充填してあり、使用時に注入ノズル内等で混合するもの（２液性）が存在している。２液性の発泡ポリウレタンは、２種類のポリウレタン原料が別個の高圧容器に充填してあり、使用時に注入ノズル内等で混合させ化学反応により硬化させるタイプの発泡ポリウレタンである。発泡剤は、２種類のポリウレタン原料と一緒に高圧容器に充填してあるものが一般的である。２液性のポリウレタンは、１液性の発泡ポリウレタンよりも発泡量が大きく発泡不良が生じ難いため、施工時に取り扱い易い。   In general commercial products, two types of polyurethane raw materials are filled in the same high-pressure vessel, and mixed in the high-pressure vessel at the time of use (one component) and two types of polyurethane raw materials are separated into separate high-pressure vessels There are those that are mixed in the injection nozzle during use (two-component). The two-component foamed polyurethane is a type of foamed polyurethane in which two types of polyurethane raw materials are filled in separate high-pressure containers and mixed in an injection nozzle or the like at the time of use and cured by a chemical reaction. The foaming agent is generally filled in a high-pressure container together with two types of polyurethane raw materials. Two-component polyurethane has a larger amount of foaming than one-component foamed polyurethane and is less likely to cause poor foaming.

このように、改装窓又は新設した窓構造体において、空間部分の略全体に発泡ポリウレタンを充填することで、止水性、気密性、断熱性、遮音性が高まるだけでなく、接合強度が高まり、耐風圧性能が増す。新設窓枠１と既設窓枠２との間の空間部分、或いは、新設窓枠１と躯体５との間の空間部分は、新設窓枠１の外周側、すなわち窓枠の上下左右の四辺に生じるが、それら四辺全ての空間部分に発泡ポリウレタンが充填される。但し、当該空間部分の全てに一切の隙間なく発泡ポリウレタンを充填することを要求するものではなく、発泡ポリウレタンの発泡不足や充填量の不足により、多少の隙間が残存しても差し支えない。   In this way, in the refurbished window or the newly established window structure, by filling the entire area of the space with foamed polyurethane, not only the waterproofing, airtightness, heat insulation, and sound insulation properties are increased, but also the bonding strength is increased. Increases wind pressure resistance. The space portion between the new window frame 1 and the existing window frame 2 or the space portion between the new window frame 1 and the housing 5 is on the outer peripheral side of the new window frame 1, that is, on the four sides of the window frame. Although it occurs, the foamed polyurethane is filled in the spaces on all four sides. However, it is not required to fill all of the space part with foamed polyurethane without any gaps, and some gaps may remain due to insufficient foaming or insufficient amount of foamed polyurethane.

発泡ポリウレタンの充填作業は、新設窓枠１と既設窓枠２との間の空間部分、或いは、新設窓枠１と躯体５との間の空間部分の所望の箇所に注入ノズルを差し込み、２種類のポリウレタン原料と発泡剤とを、高圧容器内（１液性）又は注入ノズル内等（２液性）で混合しつつ注入するなどの方法によって行う。発泡ポリウレタンは、注入（充填）された箇所から徐々に発泡して空間部分を埋めていき、最終的には空間部分の隅々にまで行き渡る。このようにして、人の手が届かない隙間にも簡単に発泡ポリウレタンを充填することができるため、注入ノズルを差し込めない隙間に対しても発泡ポリウレタンを充填することが可能となる。   There are two types of foaming polyurethane filling operations: an injection nozzle is inserted into a desired portion of the space between the new window frame 1 and the existing window frame 2 or the space between the new window frame 1 and the housing 5. The polyurethane raw material and the foaming agent are injected while being mixed in a high-pressure vessel (one-component) or in an injection nozzle (two-component). The foamed polyurethane gradually foams from the injected (filled) portion to fill the space portion, and finally reaches every corner of the space portion. In this way, the polyurethane foam can be easily filled into the gap that cannot be reached by human hands, and therefore, the polyurethane foam can be filled into the gap where the injection nozzle cannot be inserted.

仮に、発泡ポリウレタンを過剰に充填してしまい、空間部分から発泡ウレタンが溢れ出てしまっても、硬化後にカッターナイフなどで溢れ出た発泡ポリウレタン部分だけを簡単に削ぎ落とすことができるので、充填する量を気にせずに作業を行うことができる。そして、発泡ポリウレタンは、その種類によって異なるが、一般に約２分〜２０分間で硬化し、既設窓枠２と新設窓枠１とを強固に接着する。充填作業は、熟練の技術を一切要せず、非常に簡便に、且つ、短時間で完了することができ、極めて高い耐震性、免震性、制振性、耐風圧性、止水性、気密性、断熱性、又は、遮音性を得ることができる。   Even if the polyurethane foam is excessively filled and the urethane foam overflows from the space, only the polyurethane foam that overflows with a cutter knife after curing can be easily scraped off. You can work without worrying about the amount. And although polyurethane foam changes with kinds, generally it hardens | cures in about 2 minutes-20 minutes, and adheres the existing window frame 2 and the new window frame 1 firmly. Filling work does not require any skilled skills, can be completed very easily and in a short time, and has extremely high earthquake resistance, seismic isolation, vibration control, wind pressure resistance, waterstop, and airtightness , Heat insulation or sound insulation can be obtained.

また、発泡ポリウレタンは硬化反応による発熱量が大きいため、その温度を測定することにより、発泡不良による不具合を検出することができる。通常、新設窓枠と既設窓枠との間の空間部分に充填した発泡ポリウレタンは、大部分は外部から見えないため、その発泡状態や硬化状態を視認することができないが、未だ硬化していない状態の発泡ポリウレタンの一部に、温度計の温度検知部を挿入して測定することで、発泡ポリウレタンの発泡状態や硬化状態の良否を簡易に判断することも可能である。発泡ポリウレタンが硬化する際に発する化学反応熱による温度上昇を検知することにより、発泡ポリウレタンの発泡状態や硬化状態の良否を簡易に判断できる。発泡ポリウレタン原料が硬化する際には化学反応により発熱するが、発熱量が小さい場合は、化学反応が十分に生じておらず、発泡ポリウレタンの発泡状態及び硬化状態が不完全となっている可能性がある。発泡状態及び硬化状態が不完全な場合は、新設窓枠と既設窓枠の接着強度が不十分になり、また、窓枠間の空間部分に大きな空洞が残存することがあり、耐震性、免震性、制振性、耐風圧性、止水性、気密性、断熱性、又は、遮音性が低下する。   In addition, since foamed polyurethane generates a large amount of heat due to the curing reaction, it is possible to detect defects due to defective foaming by measuring the temperature. Usually, most of the polyurethane foam filled in the space between the new window frame and the existing window frame cannot be seen from the outside, so its foamed state and cured state cannot be visually recognized, but it has not yet been cured. It is also possible to easily determine whether the foamed polyurethane is in a foamed state or a cured state by inserting a temperature detection part of a thermometer into a part of the foamed polyurethane in the state and measuring. By detecting the temperature rise due to the heat of chemical reaction generated when the polyurethane foam is cured, it is possible to easily determine whether the foamed polyurethane has a foamed state or a cured state. When the foamed polyurethane raw material is cured, it generates heat due to a chemical reaction, but if the calorific value is small, the chemical reaction may not have occurred sufficiently, and the foamed polyurethane may be in an incompletely foamed and cured state. There is. If the foamed or hardened state is incomplete, the bond strength between the new window frame and the existing window frame will be insufficient, and a large cavity may remain in the space between the window frames. Seismic properties, vibration control properties, wind pressure resistance, water blocking properties, airtightness, heat insulation properties, or sound insulation properties are reduced.

発泡ポリウレタンは断熱性が高いため、表面温度と内部温度が大きく異なる。したがって、正確な温度計測のためには、温度計の温度検知部を、充填した発泡ポリウレタンのなるべく中心部に挿入する必要がある。良否判断の基準となる温度は、使用する発泡ポリウレタンの種類により異なるため、適宜、基準となる温度を設けることが可能であるが、２液性簡易発泡硬質ウレタンフォーム（例えば、フォモジャパン株式会社製、品番：♯２２０５）の場合には、最高温度が１１０℃以上に上昇すれば、十分に発泡及び硬化したものと判断できる。より好ましくは１２０℃以上である。   Since the polyurethane foam has high heat insulation properties, the surface temperature and the internal temperature are greatly different. Therefore, for accurate temperature measurement, it is necessary to insert the temperature detection part of the thermometer as centrally as possible in the filled foamed polyurethane. The reference temperature for pass / fail judgment varies depending on the type of foamed polyurethane to be used. Therefore, it is possible to appropriately set the reference temperature, but a two-component simple foamed rigid urethane foam (for example, manufactured by Fomo Japan Co., Ltd.) In the case of product number: # 2205), if the maximum temperature rises to 110 ° C. or higher, it can be determined that the foam has been sufficiently foamed and cured. More preferably, it is 120 ° C. or higher.

本発明における粘着テープとは、紙製のクラフト粘着テープ、布製の布粘着テープ、セロハンテープ、延伸ポリプロピレン製のＯＰＰ粘着テープなど、新設窓枠１と既設窓枠２との間の隙間部分を窓枠に接着するようにして塞ぐことのできるテープ状の素材であれば、いずれでも良い。発泡硬化体４を充填する前に粘着テープで隙間部分を塞ぐことで、充填された発泡硬化体４が隙間部分から溢れ出ないようにすることができる。例えば、透明又は半透明の粘着テープであれば、新設窓枠１と既設窓枠２との間の空間部分に注入された発泡硬化体４の充填具合を見ることができるため、効率良く発泡硬化体４を充填でき、さらに最適な発泡硬化体４の充填量を見極めることができるので、発泡硬化体４の使用量を節約することができる。   The adhesive tape in the present invention refers to a gap between the new window frame 1 and the existing window frame 2 such as a paper craft adhesive tape, a cloth adhesive tape, a cellophane tape, and a stretched polypropylene OPP adhesive tape. Any tape-like material that can be closed by adhering to the frame may be used. By filling the gap portion with the adhesive tape before filling the foam cured body 4, it is possible to prevent the filled foam cured body 4 from overflowing from the gap portion. For example, if it is a transparent or semi-transparent adhesive tape, the filling condition of the foamed cured body 4 injected into the space between the new window frame 1 and the existing window frame 2 can be seen. Since the body 4 can be filled and the optimum filling amount of the foam cured body 4 can be determined, the amount of use of the foam cured body 4 can be saved.

なお、粘着テープは、片面だけに粘着剤が塗られたものだけでなく、いわゆる両面テープのように、両面に粘着剤が塗られたものを使用しても良い。例えば、両面テープを用いた場合、新設窓枠１と既設窓枠２との間の隙間部分を前記の化粧部材によって塞ぐ場合、両面テープの上から両面テープに貼り付くように化粧部材を接着させることができるため、非常に簡便に効率良く作業を行うことができる。片面テープを用いた場合でも、粘着テープを残したまま化粧部材を取り付けることはできるが、粘着テープが不要な場合は、化粧部材を取り付ける前に粘着テープを剥がす必要がある。この場合は、発泡硬化体４が硬化したのちに粘着テープを剥がすことで、充填された発泡硬化体４が隙間部分から溢れ出ることもなく、簡単に粘着テープを剥がして化粧部材を取り付けることができる。   The pressure-sensitive adhesive tape is not limited to one coated with a pressure-sensitive adhesive on one side, but may be one having a pressure-sensitive adhesive coated on both sides, such as a so-called double-sided tape. For example, when a double-sided tape is used, when the gap between the new window frame 1 and the existing window frame 2 is closed by the decorative member, the decorative member is adhered to the double-sided tape so as to stick to the double-sided tape. Therefore, the work can be performed very simply and efficiently. Even when a single-sided tape is used, the decorative member can be attached while leaving the adhesive tape, but when the adhesive tape is unnecessary, it is necessary to peel off the adhesive tape before attaching the decorative member. In this case, by removing the adhesive tape after the foam cured body 4 is cured, the filled foam cured body 4 can be easily peeled off and attached to the decorative member without overflowing from the gap portion. it can.

発泡ポリウレタンの充填作業に際し、壁部とサッシとの間の空間部分に仮止め用のスペーサを、等間隔毎（例えば、３５〜４０ｃｍ毎）に挿入し、窓本体を壁部に固定しても良い。発泡ポリウレタンが充填された後、仮止め用のスペーサを外し、スペーサが挿入されていた部分（発泡ポリウレタンが充填されていない部分）にも発泡ポリウレタンを注入することで、窓構造体が得られる。   When filling polyurethane foam, temporary fixing spacers are inserted into the space between the wall and the sash at regular intervals (for example, every 35 to 40 cm), and the window body is fixed to the wall. good. After filling with the foamed polyurethane, the temporary fixing spacer is removed, and the foamed polyurethane is injected also into the part where the spacer is inserted (the part not filled with the foamed polyurethane), thereby obtaining the window structure.

本発明は、新築だけでなく、築年数が数十年経過した建物、マンション、アパート、ホテル、病院、学校、公共施設等における窓又は扉の取替え工事において利用できる。また、現場で発生する騒音問題も騒音が小さく、建付けにおいても溶接しないため、火気の心配がなく、環境問題においてもエコ工法として推奨できる。また、現在のところ、油を使用する工場（例えば、自動車メーカーの工場や化学製品を使用する工場等）は、窓の修理が困難であるため、この工法を用いて施工されることが期待される。   The present invention can be used not only for new construction but also for window or door replacement work in buildings, condominiums, apartments, hotels, hospitals, schools, public facilities, etc. that have been built for several decades. In addition, noise problems that occur on site are also low in noise and are not welded even during construction, so there is no concern about fire and it can be recommended as an eco method for environmental problems. In addition, at present, factories that use oil (for example, automakers' factories or chemical products) are difficult to repair windows, so it is expected to be constructed using this method. The
