Description

本発明は、扉の改修方法、及び扉に関する。 The present invention relates to a door repair method and a door.

従来、建物の開口部に設けられている扉を対象とした技術であって、扉によって区画される空間の気密性を高めるための技術の一つとして、開口部の周縁に設けられた扉枠と、扉枠に対して丁番を介して取り付けられた扉本体であって開口部を開閉する扉本体と、扉枠の部分のうち開口部の周縁側の部分に設けられた気密材であって、扉本体によって開口部を全閉した状態において気密材と開閉体との当接により上記空間の気密性を高めるための気密材と、を備えた技術が提案されている（例えば、特許文献１参照）。 Conventionally, it is a technology for doors provided at the opening of a building, and as one of the technologies for improving the airtightness of the space partitioned by the door, a door frame provided at the periphery of the opening. A door body that is attached to the door frame via a number and opens and closes the opening, and an airtight material provided on the peripheral edge side of the opening in the door frame. Further, a technique has been proposed comprising an airtight material for enhancing the airtightness of the space by abutting the airtight material and the opening / closing body in a state where the opening is fully closed by the door body (for example, Patent Document). See 1).

また、このような扉の改修方法については、例えば、まず、扉枠を残存させながら扉本体及び丁番を撤去し、次いで、残存させた扉枠に対して平鋼を介して新設される新規丁番を取り付けた後に、新設される扉本体を新規丁番に取り付ける方法がある。このような改修方法により、平鋼によって新規丁番の取り付けに用いるネジの必要はめ合い長さを確保しやすくなるので、新規丁番を扉枠に対して強固に固定することが可能となる。 Regarding the method of repairing such a door, for example, first, the door body and the hinge are removed while the door frame remains, and then the remaining door frame is newly installed via flat steel. After attaching the hinge, there is a method of attaching the newly installed door body to the new hinge. By such a repair method, it becomes easy to secure the necessary fitting length of the screw used for attaching the new hinge by the flat steel, so that the new hinge can be firmly fixed to the door frame.

Further, as shown in FIG. 1, the horizontal frame material main body 13a is provided with a recess and an airtight recess (not shown), and the recess and the airtight recess are the recess 11d and the airtight of the vertical frame material main body 11a described above. It is configured in substantially the same manner as the recess 11e.

固定材は、横枠材本体１３ａを躯体２に対して固定するためのものである。この固定材は、板状体にて形成されており、具体的には、当該固定材の前後方向の長さが横枠材本体１３ａのコ字状の開放端部における前後方向の長さと略同一（又はそれ以上の長さ）であり、当該固定材の左右方向の長さが横枠材本体１３ａの左右方向の長さよりも短くなるように形成されている。また、この固定材は、横枠材本体１３ａのコ字状の開放端部側（横枠材本体１３ａの上下方向の外側の端部側）において、所定間隔を隔てて左右方向に沿って複数並設配置されており、横枠材本体１３ａ及び躯体２に対して溶接等によって固定されている。 The fixing material is for fixing the horizontal frame material main body 13a to the skeleton 2. This fixing material is formed of a plate-like body, and specifically, the length of the fixing material in the front-rear direction is abbreviated as the length in the front-rear direction at the U-shaped open end of the horizontal frame material main body 13a. The length is the same (or longer), and the fixing material is formed so that the length in the left-right direction is shorter than the length in the left-right direction of the horizontal frame member main body 13a. Further, a plurality of the fixing members are provided along the left-right direction at predetermined intervals on the U-shaped open end side of the horizontal frame material main body 13a (the outer end side in the vertical direction of the horizontal frame material main body 13a). They are arranged side by side and are fixed to the horizontal frame material main body 13a and the skeleton 2 by welding or the like.

既存気密部は、上側横枠材１３又はくつずり横枠材１４と新規開閉体２０又は後述の既存開閉体１１０との相互間の気密性を高めるための気密部である。この既存気密部は、例えば公知の長尺な気密材（一例として、エアタイトゴム等）を用いて構成されており、気密凹部において横枠材本体１３ａの左右方向の略全長にわたって埋設されている。なお、以下では、既存気密部のうち、上側横枠材１３に設けられた既存気密部を「上側既存気密部」と称し、くつずり横枠材１４に設けられた既存気密部を「くつずり側既存気密部」と称する。 The existing airtight portion is an airtight portion for enhancing the airtightness between the upper horizontal frame member 13 or the slippery horizontal frame member 14 and the new opening / closing body 20 or the existing opening / closing body 110 described later. This existing airtight portion is configured by using, for example, a known long airtight material (for example, airtight rubber or the like), and is embedded in the airtight recess over substantially the entire length of the horizontal frame material main body 13a in the left-right direction. In the following, among the existing airtight portions, the existing airtight portion provided on the upper horizontal frame member 13 will be referred to as an "upper existing airtight portion", and the existing airtight portion provided on the slipping horizontal frame member 14 will be referred to as "kutsuzuri".

（構成－気密構造）
図２に戻り、次に、改修後扉１の気密構造について説明する。この改修後扉１は、全閉状態において、当該改修後扉１の気密性を高めるための気密構造を備えている。そして、この気密構造の特徴については、実施の形態１では、図２に示すように、新規開閉体２０に当接部５０が設けられている。 (Structure-airtight structure)
Returning to FIG. 2, next, the airtight structure of the door 1 after the repair will be described. The repaired door 1 has an airtight structure for enhancing the airtightness of the repaired door 1 in a fully closed state. As for the feature of this airtight structure, in the first embodiment, as shown in FIG. 2, the new opening / closing body 20 is provided with the contact portion 50.

当接部５０は、全閉状態において当該当接部５０と戸尻側既存気密部１１ｃとの当接により戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を高めることを可能にする当接手段である。この当接部５０は、図２に示すように、新規開閉体２０において戸尻側既存気密部１１ｃに向けて突出するように設けられている。具体的には、当接部５０が新規開閉体２０の建物の屋内側の側面と面一となるように、新規開閉体２０から左右方向の外側（図２では、右側）に向けて張り出されている（より具体的には、図２に示すように、新規開閉体２０の側面のうち新規ヒンジ部４０が取り付けられる側面よりも右側に突出するように設けられている）と共に、新規開閉体２０の上下方向の略全長にわたって形成されている。 The abutting portion 50 enhances the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20 by abutting the abutting portion 50 with the existing airtight portion 11c on the door tail side in a fully closed state. It is a contact means that enables. As shown in FIG. 2, the contact portion 50 is provided so as to project toward the existing airtight portion 11c on the door tail side in the new opening / closing body 20. Specifically, the contact portion 50 projects from the new opening / closing body 20 toward the outside in the left-right direction (right side in FIG. 2) so as to be flush with the indoor side surface of the new opening / closing body 20. (More specifically, as shown in FIG. 2, the side surface of the new opening / closing body 20 is provided so as to project to the right side of the side surface to which the new hinge portion 40 is attached). It is formed over substantially the entire length of the body 20 in the vertical direction.

また、当接部５０の大きさについては任意であるが、実施の形態１では、全閉状態において当接部５０と戸尻側既存気密部１１ｃとが当接可能な大きさに設定しており、具体的には、当接部５０の先端から基端までの長さＣＬを、取付補助材３０の厚さと略同一に設定している。これにより、全閉状態において当接部５０と戸尻側既存気密部１１ｃとを確実に当接させながら、新規開閉体２０の回動によって当接部５０と戸尻側縦枠材１１とが接触することで損傷することを抑制でき、全閉状態において戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保しながら、当接部５０が健全な状態を維持しやすくなる。ただし、上記設定に限らず、例えば、当接部５０の先端から基端までの長さＣＬを、取付補助材３０の厚さよりも長く設定してもよい。 The size of the contact portion 50 is arbitrary, but in the first embodiment, the size is set so that the contact portion 50 and the existing airtight portion 11c on the door tail side can come into contact with each other in the fully closed state. Specifically, the length CL from the tip end to the base end of the contact portion 50 is set to be substantially the same as the thickness of the mounting auxiliary material 30. As a result, while the contact portion 50 and the existing airtight portion 11c on the door tail side are surely brought into contact with each other in the fully closed state, the contact portion 50 and the door tail side vertical frame member 11 are brought into contact with each other by the rotation of the new opening / closing body 20. Damage can be suppressed by contact, and the contact portion 50 maintains a sound state while ensuring the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20 in the fully closed state. It will be easier. However, the present invention is not limited to the above setting, and for example, the length CL from the tip end to the base end of the contact portion 50 may be set longer than the thickness of the mounting auxiliary material 30.

また、この当接部５０の形成方法については任意であるが、実施の形態１では、新規開閉体２０を構成する表面材（図２では、屋内側表面材２３）の一部を折り返すことにより形成している。具体的には、図２に示すように、当接部５０が新規開閉体２０の当該当接部５０以外の部分よりも戸尻側縦枠材１１側（図２では、右側）に向けて突出するように、屋内側表面材２３の戸尻側部分を折り返すことにより形成している。これにより、当接部５０を新規開閉体２０とは別体に形成する場合に比べて、当接部５０と周辺部材との意匠の調和を図ることができ、改修後扉１の意匠性を維持しやすくなる。また、例えば、当接部５０の先端部と人の手とが触れることで当該手が損傷することを回避でき、改修後扉１の使用時における安全性を確保しやすくなる。さらに、当接部５０を取り付ける手間を省略でき、改修作業を効率的に行うことが可能となる。 The method of forming the contact portion 50 is arbitrary, but in the first embodiment, a part of the surface material (in FIG. 2, the indoor side surface material 23 in FIG. 2) constituting the new opening / closing body 20 is folded back. Is forming. Specifically, as shown in FIG. 2, the contact portion 50 faces the door tail side vertical frame member 11 side (right side in FIG. 2) with respect to the portion of the new opening / closing body 20 other than the contact portion 50. It is formed by folding back the door tail side portion of the indoor side surface material 23 so as to protrude. As a result, the design of the abutting portion 50 and the peripheral members can be harmonized as compared with the case where the abutting portion 50 is formed separately from the new opening / closing body 20, and the design of the door 1 after repair can be improved. It will be easier to maintain. Further, for example, it is possible to prevent the hand from being damaged by the contact between the tip of the contact portion 50 and a human hand, and it becomes easy to secure the safety when the door 1 is used after the repair. Further, the trouble of attaching the contact portion 50 can be omitted, and the repair work can be efficiently performed.

このような気密構造により、新規ヒンジ部４０を強固に固定できると共に、全閉状態において当接部５０によって戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保することができ、改修後扉１の使用性を高めることが可能となる。 With such an airtight structure, the new hinge portion 40 can be firmly fixed, and the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20 is ensured by the contact portion 50 in the fully closed state. It is possible to improve the usability of the door 1 after the repair.

（扉の改修方法）
続いて、扉の改修方法について説明する。図２、図４から図６に示すように、改修前に開口部３に既設されている図４の扉１０１（以下、「改修前扉１０１」と称する）を図２の改修後扉１に改修する改修方法は、撤去工程、修繕工程、第１取付工程、第２取付工程、及び塗装工程を含んでいる。 (How to repair the door)
Next, the method of repairing the door will be described. As shown in FIGS. 2 and 4 to 6, the door 101 of FIG. 4 (hereinafter referred to as “pre-repair door 101”) existing in the opening 3 before the refurbishment is replaced with the post-repair door 1 of FIG. The repair method to be repaired includes a removal step, a repair step, a first mounting step, a second mounting step, and a painting step.

ここで、改修前扉１０１の具体的な構成については任意であるが、実施の形態１では、図４に示すように、既存枠体１０、既存開閉体１１０、及び既存ヒンジ部１２０を備えている。このうち、既存枠体１０は、図１の既存枠体１０と同一のものである。また、既存開閉体１１０は、開口部３を開閉するための平板状の開閉体であり、当接部５０が省略され、且つ既存開閉体１１０の平面形状の大きさが新規開閉体２０の平面形状の大きさに比べて若干大きく設定されていることを除き、新規開閉体２０と略同様に構成されている。また、既存ヒンジ部１２０は、既存開閉体１１０を戸尻側縦枠材１１に対して回動自在に軸支するためのヒンジ部である。この既存ヒンジ部１２０は、例えば公知の丁番（一例として、掘り込み式の旗丁番等）を用いて構成されており、図４に示すように、既存開閉体１１０の戸尻側の端部（図４では、右端部）において、相互に間隔を隔てて上下方向に沿って複数並設されており、既存開閉体１１０の内部に設けられた図４の補助板１１１を介して既存開閉体１１０に対して固定具によって取り付けられ、且つ裏板１１ｆを介して戸尻側縦枠材１１に対して固定具によって取り付けられている。このような改修前扉１０１の構成により、既存ヒンジ部１２０を強固に固定できると共に、全閉状態において戸尻側既存気密部１１ｃによって戸尻側縦枠材１１と既存開閉体１１０との相互間の気密性を確保することができ、改修前扉１０１の使用性を高めることが可能となる。 Here, the specific configuration of the pre-repair door 101 is arbitrary, but in the first embodiment, as shown in FIG. 4, the existing frame body 10, the existing opening / closing body 110, and the existing hinge portion 120 are provided. There is. Of these, the existing frame body 10 is the same as the existing frame body 10 in FIG. Further, the existing opening / closing body 110 is a flat plate-shaped opening / closing body for opening / closing the opening 3, the contact portion 50 is omitted, and the size of the planar shape of the existing opening / closing body 110 is the plane of the new opening / closing body 20. It is configured in substantially the same manner as the new opening / closing body 20 except that it is set slightly larger than the size of the shape. Further, the existing hinge portion 120 is a hinge portion for rotatably supporting the existing opening / closing body 110 with respect to the door tail side vertical frame member 11. The existing hinge portion 120 is configured by using, for example, a known hinge (for example, a digging type hinge number or the like), and as shown in FIG. 4, the end of the existing opening / closing body 110 on the door tail side. A plurality of portions (in the right end portion in FIG. 4) are arranged side by side in the vertical direction at intervals from each other, and the existing opening / closing via the auxiliary plate 111 of FIG. 4 provided inside the existing opening / closing body 110. It is attached to the body 110 by a fixing tool, and is attached to the door tail side vertical frame member 11 by a fixing tool via the back plate 11f. With such a configuration of the pre-repair door 101, the existing hinge portion 120 can be firmly fixed, and in the fully closed state, the door tail side vertical frame member 11 and the existing opening / closing body 110 are mutually connected by the door tail side existing airtight portion 11c. It is possible to secure the airtightness of the door 101 and improve the usability of the pre-repair door 101.

（扉の改修方法－撤去工程）
まず、撤去工程について説明する。撤去工程は、図５に示すように、改修前扉１０１の既存開閉体１１０及び既存ヒンジ部１２０を撤去する工程である。具体的には、まず、略全開状態において既存開閉体１１０を上方に持ち上げることで、既存開閉体１１０を既存ヒンジ部１２０の一部（具体的には、戸尻側縦枠材１１に取り付けられる部分）から取り外す。そして、上記既存ヒンジ部１２０の一部に取り付けられた固定具を取り外すことで、既存ヒンジ部１２０を戸尻側縦枠材１１から取り外すことにより、撤去する。ただし、これに限らず、例えば、略全開状態において既存ヒンジ部１２０に取り付けられた固定具を取り外すことで、既存開閉体１１０及び既存ヒンジ部１２０を戸尻側縦枠材１１から同時に取り外すことにより、撤去してもよい（特に、開口部３の上方に庇がある場合には有効である）。 (Door repair method-removal process)
First, the removal process will be described. As shown in FIG. 5, the removal step is a step of removing the existing opening / closing body 110 and the existing hinge portion 120 of the pre-repair door 101. Specifically, first, by lifting the existing opening / closing body 110 upward in a substantially fully open state, the existing opening / closing body 110 is attached to a part of the existing hinge portion 120 (specifically, the door tail side vertical frame member 11). Remove from the part). Then, by removing the fixture attached to a part of the existing hinge portion 120, the existing hinge portion 120 is removed from the door tail side vertical frame member 11. However, the present invention is not limited to this, for example, by removing the fixture attached to the existing hinge portion 120 in a substantially fully open state, the existing opening / closing body 110 and the existing hinge portion 120 can be simultaneously removed from the door tail side vertical frame member 11. , May be removed (especially effective if there is an eaves above the opening 3).

（扉の改修方法－修繕工程）
次に、修繕工程について説明する。修繕工程は、撤去工程の後に、戸尻側縦枠材１１を修繕するための工程である。具体的には、戸尻側縦枠材１１に設けられた挿通孔であって、既存ヒンジ部１２０の一部（具体的には、裏板１１ｆに取り付けられる部分）を戸尻側縦枠材１１の内部に挿通させるための挿通孔（図示省略）を、図示しない塞ぎ材（一例として、パテ材又はシール材等）で塞ぐことにより、修繕する。 (Door repair method-repair process)
Next, the repair process will be described. The repair step is a step for repairing the door tail side vertical frame member 11 after the removal step. Specifically, it is an insertion hole provided in the door tail side vertical frame material 11, and a part of the existing hinge portion 120 (specifically, a portion attached to the back plate 11f) is a door tail side vertical frame material. The insertion hole (not shown) for inserting into the inside of 11 is repaired by closing it with a closing material (for example, a putty material or a sealing material) (not shown).

（扉の改修方法－第１取付工程）
次いで、第１取付工程について説明する。第１取付工程は、修繕工程の後に、取付補助材３０を戸尻側縦枠材１１に取り付ける工程である。具体的には、図６に示すように、工場等で製造された取付補助材３０であって、取付補助材３０の上下方向の長さが戸尻側縦枠材１１の長手方向の全長と略同一である取付補助材３０を戸尻側縦枠材１１の内縁側の側面に当接させた状態で、この取付補助材３０を戸尻側縦枠材１１に対して固定具３１によって固定することにより、取り付ける。これにより、取付補助材３０を戸尻側縦枠材１１に対して比較的強固に固定できると共に、新規ヒンジ部４０の取付位置の自由度を高めることができ、取付補助材３０や新規ヒンジ部４０の設置性を向上させることができる。 (Door repair method-first installation process)
Next, the first mounting step will be described. The first mounting step is a step of mounting the mounting auxiliary material 30 to the door tail side vertical frame member 11 after the repair step. Specifically, as shown in FIG. 6, in the mounting auxiliary material 30 manufactured in a factory or the like, the vertical length of the mounting auxiliary material 30 is the total length in the longitudinal direction of the door tail side vertical frame member 11. The mounting auxiliary material 30 is fixed to the door tail side vertical frame material 11 by the fixture 31 in a state where the substantially same mounting auxiliary material 30 is in contact with the side surface of the door tail side vertical frame material 11 on the inner edge side. By doing so, it is attached. As a result, the mounting auxiliary material 30 can be relatively firmly fixed to the door tail side vertical frame material 11, and the degree of freedom in the mounting position of the new hinge portion 40 can be increased, so that the mounting auxiliary material 30 and the new hinge portion can be fixed. The installability of 40 can be improved.

（扉の改修方法－第２取付工程）
次に、第２取付工程について説明する。第２取付工程は、図２に示すように、第１取付工程の後に、新規ヒンジ部４０を取付補助材３０を介して戸尻側縦枠材１１に取り付け、且つ新規開閉体２０を新規ヒンジ部４０に取り付けると共に、新規開閉体２０に当接部５０を設けることで、全閉状態において当該当接部５０と戸尻側既存気密部１１ｃとの当接により戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を高めることを可能とする工程である。具体的には、まず、新規ヒンジ部４０を、戸尻側縦枠材１１に取り付けられる部分（以下、「新規ヒンジ部４０の一部」と称する）と、新規開閉体２０に取り付けられる部分（以下、「新規ヒンジ部４０の他の一部」と称する）とに分解する。次に、新規ヒンジ部４０の一部を取付補助材３０に当接させた状態で、この新規ヒンジ部４０の一部を取付補助材３０及び戸尻側縦枠材１１に対して固定具４１によって固定する。次いで、工場等で製造された新規開閉体２０であって、屋内側表面材２３の一部を折り返すことで形成された当接部５０を有する新規開閉体２０に新規ヒンジ部４０の他の一部を当接させた状態で、この新規ヒンジ部４０の他の一部を新規開閉体２０に対して固定具４１によって固定する。そして、新規ヒンジ部４０の他の一部が新規ヒンジ部４０の一部に差し込まれるように、上記新規開閉体２０を持ち上げ且つ持ち下げることにより、取り付けてもよい。あるいは、これに限らず、例えば、まず、新規ヒンジ部４０を分解することなく、新規ヒンジ部４０の一部を取付補助材３０に当接させた状態で、この新規ヒンジ部４０の一部を取付補助材３０及び戸尻側縦枠材１１に対して固定具４１によって固定する。そして、上記工場等で製造された新規開閉体２０を新規ヒンジ部４０の他の一部に当接させた状態で、この新規開閉体２０を新規ヒンジ部４０の他の一部に対して固定具４１によって固定することにより、取り付けてもよい（特に、開口部３の上方に庇がある場合には有効である）。なお、新規ヒンジ部４０を戸尻側縦枠材１１に取り付ける際に、取付補助材３０を用いることなく、戸尻側縦枠材１１の裏板１１ｆのみを用いることも考えられるが、既存枠体１０が躯体２に取り付けられている状態では、裏板１１ｆの設置位置を確認することが難しいため、新規ヒンジ部４０を裏板１１ｆに取り付けることが困難になることから、実施の形態１では、取付補助材３０を用いることにしている。 (Door repair method-second mounting process)
Next, the second mounting process will be described. In the second mounting step, as shown in FIG. 2, after the first mounting step, the new hinge portion 40 is attached to the door tail side vertical frame member 11 via the mounting auxiliary material 30, and the new opening / closing body 20 is attached to the new hinge. By attaching to the portion 40 and providing the contact portion 50 on the new opening / closing body 20, the contact portion 50 and the existing airtight portion 11c on the door tail side come into contact with each other in the fully closed state to form the vertical frame member 11 on the door tail side. This is a step that makes it possible to improve the airtightness between the new opening / closing body 20 and the new opening / closing body 20. Specifically, first, a portion where the new hinge portion 40 is attached to the door tail side vertical frame member 11 (hereinafter referred to as "a part of the new hinge portion 40") and a portion where the new hinge portion 40 is attached to the new opening / closing body 20 (hereinafter referred to as "a part of the new hinge portion 40"). Hereinafter, it is referred to as "another part of the new hinge portion 40"). Next, with a part of the new hinge portion 40 in contact with the mounting auxiliary material 30, a part of the new hinge portion 40 is attached to the mounting auxiliary material 30 and the door tail side vertical frame member 11 with the fixture 41. Fixed by. Next, in the new opening / closing body 20 manufactured in a factory or the like, the new opening / closing body 20 having the contact portion 50 formed by folding back a part of the indoor side surface material 23 is combined with the other one of the new hinge portions 40. The other part of the new hinge portion 40 is fixed to the new opening / closing body 20 by the fixing tool 41 in a state where the portions are in contact with each other. Then, the new opening / closing body 20 may be attached by lifting and lowering the new opening / closing body 20 so that the other part of the new hinge portion 40 is inserted into the part of the new hinge portion 40. Alternatively, the present invention is not limited to this, for example, first, without disassembling the new hinge portion 40, a part of the new hinge portion 40 is brought into contact with the mounting auxiliary material 30 and a part of the new hinge portion 40 is removed. It is fixed to the mounting auxiliary material 30 and the hinge side vertical frame material 11 by the fixing tool 41. Then, in a state where the new opening / closing body 20 manufactured in the above factory or the like is in contact with another part of the new hinge portion 40, the new opening / closing body 20 is fixed to the other part of the new hinge portion 40. It may be attached by fixing it with the tool 41 (especially effective when there is an eave above the opening 3). When attaching the new hinge portion 40 to the door tail side vertical frame material 11, it is conceivable to use only the back plate 11f of the door tail side vertical frame material 11 without using the attachment auxiliary material 30, but the existing frame. In the state where the body 10 is attached to the skeleton 2, it is difficult to confirm the installation position of the back plate 11f, and it is difficult to attach the new hinge portion 40 to the back plate 11f. , The mounting auxiliary material 30 is used.

（扉の改修方法－塗装工程）
続いて、塗装工程について説明する。塗布乾燥工程は、第２取付工程の後に、既存枠体１０を塗装するための工程である。具体的には、戸尻側縦枠材１１の外表面のうち、修繕工程において塞ぎ材が取り付けられた部分及びその近傍部分に公知の塗装材（図示省略）を塗布した後に、所定時間経過するまで乾燥させることにより、塗装する。 (Door repair method-painting process)
Next, the painting process will be described. The coating / drying step is a step for painting the existing frame body 10 after the second mounting step. Specifically, a predetermined time elapses after applying a known coating material (not shown) to the portion of the outer surface of the door tail side vertical frame member 11 to which the closing material is attached and the portion in the vicinity thereof in the repair process. Paint by drying to.

以上のような改修方法により、新規ヒンジ部４０を強固に固定できると共に、全閉状態において当接部５０によって戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保することができ、改修後扉１が少なくとも改修前扉１０１と同等の使用性を維持することが可能となる。また、既存ヒンジ部１２０及び新規ヒンジ部４０の各々が丁番であるので、既存の丁番から新規の丁番に改修する際に上記改修方法を適用することができ、改修後扉１が改修前扉１０１と同等の使用性を一層維持することが可能となる。 By the above-mentioned repair method, the new hinge portion 40 can be firmly fixed, and the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20 is ensured by the contact portion 50 in the fully closed state. This makes it possible for the post-repair door 1 to maintain at least the same usability as the pre-repair door 101. Further, since each of the existing hinge portion 120 and the new hinge portion 40 is a hinge, the above repair method can be applied when repairing from an existing hinge to a new hinge, and the door 1 is repaired after the repair. It is possible to further maintain the same usability as the front door 101.

（実施の形態の効果）
このように実施の形態１によれば、撤去工程の後に、戸尻側縦枠材１１の内縁側の側面に設けられる取付補助材３０を戸尻側縦枠材１１に取り付ける第１取付工程と、第１取付工程の後に行われる第２取付工程であって、撤去工程において既存開閉体１１０及び既存ヒンジ部１２０が撤去された場合には、新規ヒンジ部４０を取付補助材３０を介して戸尻側縦枠材１１に取り付け、且つ新規開閉体２０を新規ヒンジ部４０に取り付けると共に、戸尻側既存気密部１１ｃに向けて突出した当接部５０を新規開閉体２０に設けることで、全閉状態において当該当接部５０と戸尻側既存気密部１１ｃとの当接により戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を高めることを可能とする第２取付工程と、を含むので、新規ヒンジ部４０を強固に固定できると共に、全閉状態において当接部５０によって戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保することができ、改修後扉１が少なくとも改修前扉１０１と同等の使用性を維持することが可能となる。 (Effect of embodiment)

Since the process is included, the new hinge portion 40 can be firmly fixed, and the abutting portion 50 ensures the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20 in the fully closed state. This makes it possible for the post-repair door 1 to maintain at least the same usability as the pre-repair door 101.

また、当接部５０の先端から基端までの長さＣＬを、取付補助材３０の厚さと略同一としたので、全閉状態において当接部５０と戸尻側既存気密部１１ｃとを確実に当接させながら、新規開閉体２０の回動によって当接部５０と戸尻側縦枠材１１とが接触することで損傷することを抑制できる。よって、全閉状態において戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保しながら、当接部５０が健全な状態を維持しやすくなる。 Further, since the length CL from the tip end to the base end of the contact portion 50 is substantially the same as the thickness of the mounting auxiliary material 30, the contact portion 50 and the existing airtight portion 11c on the door tail side are surely secured in the fully closed state. It is possible to prevent damage caused by the contact between the contact portion 50 and the door tail side vertical frame member 11 due to the rotation of the new opening / closing body 20 while making contact with the door tail side vertical frame member 11. Therefore, it becomes easy to maintain a sound state of the contact portion 50 while ensuring the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20 in the fully closed state.

また、新規開閉体２０に設けられる当接部５０が、新規開閉体２０を構成する表面材の一部を折り返すことにより形成されるので、当接部５０を新規開閉体２０とは別体に形成する場合に比べて、当接部５０と周辺部材との意匠の調和を図ることができ、改修後扉１の意匠性を維持しやすくなる。また、例えば、当接部５０の先端部と人の手とが触れることで当該手が損傷することを回避でき、改修後扉１の使用時における安全性を確保しやすくなる。さらに、当接部５０を取り付ける手間を省略でき、改修作業を効率的に行うことが可能となる。 Further, since the contact portion 50 provided on the new opening / closing body 20 is formed by folding back a part of the surface material constituting the new opening / closing body 20, the contact portion 50 is separated from the new opening / closing body 20. Compared with the case of forming, the design of the contact portion 50 and the peripheral member can be harmonized, and it becomes easier to maintain the design of the door 1 after the repair. Further, for example, it is possible to prevent the hand from being damaged by the contact between the tip of the contact portion 50 and a human hand, and it becomes easy to secure the safety when the door 1 is used after the repair. Further, the trouble of attaching the contact portion 50 can be omitted, and the repair work can be efficiently performed.

また、第１取付工程においては、取付補助材３０を戸尻側縦枠材１１の長手方向の全長にわたって設けるので、取付補助材３０又は新規ヒンジ部４０を取り付けるための固定具３１又は固定具４１の固定箇所や固定数を状況に応じて設定しやすくなる。よって、例えば、取付補助材３０を戸尻側縦枠材１１に対して比較的強固に固定できると共に、新規ヒンジ部４０の取付位置の自由度を高めることができ、取付補助材３０や新規ヒンジ部４０の設置性を向上させることが可能となる。 Further, in the first mounting step, since the mounting auxiliary material 30 is provided over the entire length of the door tail side vertical frame member 11 in the longitudinal direction, the fixing tool 31 or the fixing tool 41 for mounting the mounting auxiliary material 30 or the new hinge portion 40 is provided. It becomes easier to set the fixed location and the fixed number according to the situation. Therefore, for example, the mounting auxiliary material 30 can be relatively firmly fixed to the door tail side vertical frame material 11, and the degree of freedom in the mounting position of the new hinge portion 40 can be increased, so that the mounting auxiliary material 30 and the new hinge can be fixed. It is possible to improve the installability of the unit 40.

また、既存ヒンジ部１２０が丁番であり、新規ヒンジ部４０が丁番であるので、既存の丁番から新規の丁番に改修する際に当該改修方法を適用することができ、改修後扉１が改修前扉１０１と同等の使用性を一層維持することが可能となる。 Further, since the existing hinge portion 120 is a hinge and the new hinge portion 40 is a hinge, the repair method can be applied when repairing from an existing hinge to a new hinge, and the door after repair can be applied. 1 can further maintain the same usability as the pre-repair door 101.

実施の形態２において、図７に示すように、既存枠体１０の戸尻側縦枠材１１及び戸先側縦枠材１２の各々は、縦枠材本体１１ａ、固定材１１ｂ、及び新規気密部２１０を備えている。また、戸尻側縦枠材１１は、これらの構成要素に加えて、裏板１１ｆをさらに備えている。このうち、新規気密部２１０は、戸尻側縦枠材１１又は戸先側縦枠材１２と新規開閉体２０との相互間の気密性を高めるための気密部である。この新規気密部２１０は、例えば公知の長尺な気密材（一例として、エアタイトゴム等）を用いて構成されており、図７に示すように、縦枠材本体１１ａの気密凹部１１ｅにおいて縦枠材本体１１ａの上下方向の略全長にわたって埋設されている。なお、以下では、新規気密部２１０のうち、戸尻側縦枠材１１に設けられた新規気密部２１０を「戸尻側新規気密部２１０」と称し、戸先側縦枠材１２に設けられた新規気密部（図示省略）を「戸先側新規気密部」と称する。 In the second embodiment, as shown in FIG. 7, each of the door tail side vertical frame material 11 and the door end side vertical frame material 12 of the existing frame body 10 has a vertical frame material main body 11a, a fixing material 11b, and a new airtightness. The unit 210 is provided. Further, the door tail side vertical frame member 11 further includes a back plate 11f in addition to these components. Of these, the new airtight portion 210 is an airtight portion for enhancing the airtightness between the door tail side vertical frame member 11 or the door end side vertical frame member 12 and the new opening / closing body 20. The new airtight portion 210 is configured by using, for example, a known long airtight material (for example, airtight rubber or the like), and as shown in FIG. 7, the vertical frame is formed in the airtight recess 11e of the vertical frame material main body 11a. It is buried over almost the entire length of the material body 11a in the vertical direction.

The new airtight part (not shown) is referred to as a "door-to-door side new airtight part".

また、上側横枠材１３及びくつずり横枠材１４の各々は、横枠材本体１３ａ、固定材（図示省略）、及び新規気密部（図示省略）を備えている。このうち、新規気密部は、例えば公知の長尺な気密材（一例として、エアタイトゴム等）を用いて構成されており、横枠材本体１３ａの気密凹部において横枠材本体１３ａの左右方向の略全長にわたって埋設されている。なお、以下では、新規気密部のうち、上側横枠材１３に設けられた新規気密部を「上側新規気密部」と称し、くつずり横枠材１４に設けられた新規気密部を「くつずり側新規気密部」と称する。 Further, each of the upper horizontal frame material 13 and the slippery horizontal frame material 14 includes a horizontal frame material main body 13a, a fixing material (not shown), and a new airtight portion (not shown). Of these, the new airtight portion is configured by using, for example, a known long airtight material (for example, airtight rubber or the like), and is formed in the airtight recess of the horizontal frame material main body 13a in the left-right direction of the horizontal frame material main body 13a. It is buried over almost the entire length. In the following, among the new airtight portions, the new airtight portion provided on the upper horizontal frame member 13 will be referred to as an "upper new airtight portion", and the new airtight portion provided on the slipping horizontal frame member 14 will be referred to as "kutsuzuri". It is called "side new airtight part".

（構成－気密構造）
次に、改修後扉２０１の気密構造について説明する。この気密構造の特徴については、実施の形態２では、図７、図８に示すように、戸尻側新規気密部２１０に当接部２２０が設けられている。 (Structure-airtight structure)
Next, the airtight structure of the repaired door 201 will be described. Regarding the feature of this airtight structure, in the second embodiment, as shown in FIGS. 7 and 8, a contact portion 220 is provided on the door tail side new airtight portion 210.

当接部２２０は、全閉状態において当該当接部２２０と新規開閉体２０との当接により戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を高めることを可能にする当接手段である。この当接部２２０は、図７、図８に示すように、戸尻側新規気密部２１０において新規開閉体２０に向けて突出するように設けられている。具体的には、当接部２２０が戸尻側新規気密部２１０から左右方向の内側（図８では、左側）に向けて張り出されている（より具体的には、図６の戸尻側既存気密部１１ｃよりも左側に突出するように設けられている）と共に、戸尻側新規気密部２１０の上下方向の略全長にわたって形成されている。 The abutting portion 220 makes it possible to improve the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20 by abutting the abutting portion 220 with the new opening / closing body 20 in a fully closed state. It is a contact means to be used. As shown in FIGS. 7 and 8, the contact portion 220 is provided so as to project toward the new opening / closing body 20 in the door tail side new airtight portion 210. Specifically, the contact portion 220 projects from the new airtight portion 210 on the door tail side toward the inside in the left-right direction (left side in FIG. 8) (more specifically, the door tail side in FIG. 6). It is provided so as to project to the left side of the existing airtight portion 11c), and is formed over substantially the entire length of the new airtight portion 210 on the door tail side in the vertical direction.

また、当接部２２０の大きさについては任意であるが、実施の形態２では、図８に示すように、実施の形態１と同様に、当接部２２０の先端から基端までの長さＣＬを、取付補助材３０の厚さと略同一に設定している。ここで、「当接部２２０の基端」とは、実施の形態２では、戸尻側新規気密部２１０の部分のうち戸尻側既存気密部１１ｃの左右方向の内側の端部（図８では、左端部）に対応する部分として説明する。これにより、全閉状態において当接部２２０と新規開閉体２０とを確実に当接させながら、新規開閉体２０の回動によって当接部２２０と戸尻側縦枠材１１とが接触することで損傷することを抑制でき、全閉状態において戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保しながら、当接部２２０が健全な状態を維持しやすくなる。 The size of the contact portion 220 is arbitrary, but in the second embodiment, as shown in FIG. 8, the length from the tip end to the base end of the contact portion 220 is the same as in the first embodiment. The CL is set to be substantially the same as the thickness of the mounting auxiliary material 30. Here, the "base end of the contact portion 220" is the inner end portion in the left-right direction of the existing airtight portion 11c on the door tail side of the portion of the new airtight portion 210 on the door tail side in the second embodiment (FIG. 8). Then, it will be described as a part corresponding to the left end part). As a result, while the contact portion 220 and the new opening / closing body 20 are surely brought into contact with each other in the fully closed state, the contact portion 220 and the door tail side vertical frame member 11 come into contact with each other due to the rotation of the new opening / closing body 20. In the fully closed state, the contact portion 220 can easily maintain a healthy state while ensuring the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20.

また、この当接部２２０の形成方法については任意であるが、実施の形態２では、気密材を射出成形することにより、当接部２２０と戸尻側新規気密部２１０とを一体に形成している。これにより、当接部２２０を戸尻側新規気密部２１０とは別体に形成する場合に比べて、当接部２２０と周辺部材との意匠の調和を図ることができ、改修後扉２０１の意匠性を維持しやすくなる。また、当接部２２０を取り付ける手間を省略でき、改修作業を効率的に行うことが可能となる。 Further, the method of forming the contact portion 220 is arbitrary, but in the second embodiment, the contact portion 220 and the new airtight portion 210 on the door tail side are integrally formed by injection molding the airtight material. ing. As a result, the design of the abutting portion 220 and the peripheral members can be harmonized as compared with the case where the abutting portion 220 is formed separately from the new airtight portion 210 on the door tail side. It becomes easier to maintain the design. In addition, the trouble of attaching the contact portion 220 can be omitted, and the repair work can be efficiently performed.

このような気密構造により、実施の形態１に係る気密構造と同様に、新規ヒンジ部４０を強固に固定できると共に、全閉状態において当接部２２０によって戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保することができ、改修後扉２０１の使用性を高めることが可能となる。 With such an airtight structure, the new hinge portion 40 can be firmly fixed as in the airtight structure according to the first embodiment, and the door tail side vertical frame member 11 and the new opening / closing body are provided by the contact portion 220 in the fully closed state. It is possible to secure the airtightness between the door 20 and the door 201, and improve the usability of the door 201 after the repair.

（扉の改修方法）
続いて、扉の改修方法について説明する。図４、図７、図９、図１０に示すように、図４に示す改修前扉１０１を図７の改修後扉２０１に改修する改修方法は、撤去工程、修繕工程、第１取付工程、第２取付工程、及び塗装工程を含んでいる。なお、修繕工程、第１取付工程、及び塗装工程は、実施の形態１に係る修繕工程、第１取付工程、及び塗装工程とそれぞれ略同様に行われるので、以下では、その説明を省略する。 (How to repair the door)
Next, the method of repairing the door will be described. As shown in FIGS. 4, 7, 9, and 10, the repair methods for repairing the front door 101 shown in FIG. 4 to the door 201 after the repair in FIG. 7 include a removal process, a repair process, and a first mounting process. It includes a second mounting process and a painting process. Since the repair step, the first mounting step, and the painting step are performed in substantially the same manner as the repair step, the first mounting step, and the painting step according to the first embodiment, the description thereof will be omitted below.

（扉の改修方法－撤去工程）
まず、撤去工程について説明する。撤去工程は、図９に示すように、改修前扉１０１の既存開閉体１１０、既存ヒンジ部１２０、及び戸尻側既存気密部１１ｃを含む既存気密部を撤去する工程である。具体的には、実施の形態１に係る撤去工程と同様に、既存開閉体１１０及び既存ヒンジ部１２０を撤去した後に、既存枠体１０から各種の既存気密部のすべてを取り外すことにより、撤去する。 (Door repair method-removal process)
First, the removal process will be described. As shown in FIG. 9, the removal step is a step of removing the existing airtight portion including the existing opening / closing body 110, the existing hinge portion 120, and the door tail side existing airtight portion 11c of the door 101 before repair. Specifically, as in the removal step according to the first embodiment, after removing the existing opening / closing body 110 and the existing hinge portion 120, all of the various existing airtight parts are removed from the existing frame body 10 to remove the existing airtight parts. ..

（扉の改修方法－第２取付工程）
次に、第２取付工程について説明する。第２取付工程は、図７に示すように、取付補助材３０を取り付ける図１０の第１取付工程が行われた後に、新規ヒンジ部４０を取付補助材３０を介して戸尻側縦枠材１１に取り付け、新規開閉体２０を新規ヒンジ部４０に取り付け、且つ、戸尻側新規気密部２１０を戸尻側縦枠材１１に取り付けると共に、新規開閉体２０又は戸尻側新規気密部２１０のいずれか一方に向けて突出した当接部２２０を新規開閉体２０又は戸尻側新規気密部２１０のいずれか他方に設けることで、全閉状態において当該当接部２２０と新規開閉体２０又は戸尻側新規気密部２１０との当接により戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を高めることを可能とする工程である。具体的には、まず、工場等で製造された各種の新規気密部（具体的には、新規開閉体２０に向けて突出した当接部２２０と一体形成された戸尻側新規気密部２１０を含む各種の新規気密部）を既存枠体１０に形成された対応する気密凹部にそれぞれ埋設する。そして、実施の形態１に係る第２取付工程と同様に、新規ヒンジ部４０を取付補助材３０を介して戸尻側縦枠材１１に取り付けると共に、新規開閉体２０を新規ヒンジ部４０に取り付ける。 (Door repair method-second mounting process)
Next, the second mounting process will be described. In the second mounting step, as shown in FIG. 7, after the first mounting step of FIG. 10 for mounting the mounting auxiliary material 30 is performed, the new hinge portion 40 is attached to the door tail side vertical frame member via the mounting auxiliary material 30. Attached to 11, the new opening / closing body 20 is attached to the new hinge portion 40, and the new airtight portion 210 on the door tail side is attached to the vertical frame material 11 on the door tail side, and the new opening / closing body 20 or the new airtight portion 210 on the door tail side is attached. By providing the contact portion 220 protruding toward either one on either the new opening / closing body 20 or the door tail side new airtight portion 210, the contact portion 220 and the new opening / closing body 20 or the door are fully closed. This is a step that makes it possible to improve the airtightness between the door tail side vertical frame member 11 and the new opening / closing body 20 by abutting with the tail side new airtight portion 210. Specifically, first, various new airtight portions manufactured in a factory or the like (specifically, a new airtight portion 210 on the door tail side integrally formed with an abutting portion 220 protruding toward the new opening / closing body 20). Various new airtight portions including) are embedded in the corresponding airtight recesses formed in the existing frame 10. Then, as in the second mounting step according to the first embodiment, the new hinge portion 40 is attached to the door tail side vertical frame member 11 via the mounting auxiliary material 30, and the new opening / closing body 20 is attached to the new hinge portion 40. ..

以上のような改修方法により、実施の形態１に係る改修方法と同様に、新規ヒンジ部４０を強固に固定できると共に、全閉状態において当接部２２０によって戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保することができ、改修後扉２０１が少なくとも改修前扉１０１と同等の使用性を維持することが可能となる。 By the repair method as described above, the new hinge portion 40 can be firmly fixed as in the repair method according to the first embodiment, and the door tail side vertical frame member 11 and the new opening / closing are newly opened / closed by the contact portion 220 in the fully closed state. The airtightness between the body 20 and the body 20 can be ensured, and the door 201 after the repair can maintain at least the same usability as the door 101 before the repair.

（実施の形態の効果）
このように実施の形態２によれば、撤去工程の後に、戸尻側縦枠材１１の内縁側の側面に設けられる取付補助材３０を戸尻側縦枠材１１に取り付ける第１取付工程と、第１取付工程の後に行われる第２取付工程であって、撤去工程において既存開閉体１１０、既存ヒンジ部１２０、及び戸尻側既存気密部１１ｃが撤去された場合には、新規ヒンジ部４０を取付補助材３０を介して戸尻側縦枠材１１に取り付け、新規開閉体２０を新規ヒンジ部４０に取り付け、且つ、戸尻側新規気密部２１０を戸尻側縦枠材１１に取り付けると共に、新規開閉体２０に向けて突出した当接部２２０を戸尻側新規気密部２１０に設けることで、全閉状態において当該当接部２２０と新規開閉体２０との当接により戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を高めることを可能とする第２取付工程と、を含むので、実施の形態１に係る扉の改修方法と同様に、新規ヒンジ部４０を強固に固定できると共に、全閉状態において当接部２２０によって戸尻側縦枠材１１と新規開閉体２０との相互間の気密性を確保することができ、改修後扉２０１が少なくとも改修前扉１０１と同等の使用性を維持することが可能となる。 (Effect of embodiment)
