Description

本発明は、サッシやドアなどの開口部装置と外壁材の間の隙間を埋めるための技術に関する。   The present invention relates to a technique for filling a gap between an opening device such as a sash and a door and an outer wall material.

従来、建物の開口部に設けられたサッシ（窓）やドアなどの開口部装置と、それを取り囲むようにして配置される外壁材の間においては、両者の間に形成される隙間からの水の浸入を防ぐための目地構造が必要とされる。   Conventionally, between an opening device such as a sash (window) or door provided in an opening of a building and an outer wall member arranged so as to surround the opening device, water from a gap formed between the two is provided. A joint structure is required to prevent the intrusion.

このような目地構造に関し、特許文献１では、開口部装置の周辺と外壁材の間にパッキンやシーリング材を設置して止水を図るとともに、パッキンやシーリング材を化粧部材によって覆い隠す構造を開示している。   With respect to such joint structure, Patent Document 1 discloses a structure in which a packing or sealing material is installed between the periphery of the opening device and the outer wall material to stop water, and the packing or sealing material is covered with a decorative member. doing.

また、この特許文献１において、開口部装置の周囲枠に沿う様にベース部材が付設され、この周囲枠とベース部材の間の隙間がパッキンで止水される。ベース部材のうち、開口部装置の角部（コーナー部など）に設置されるものは端部ベース部材として構成され、開口部装置の角部の間に設置されるものは中間部ベース部材として構成されている。   Moreover, in this patent document 1, a base member is attached along the surrounding frame of an opening part apparatus, and the clearance gap between this surrounding frame and a base member is water-stopped by packing. Of the base members, those installed at the corners (corner portions, etc.) of the opening device are configured as end base members, and those installed between the corners of the opening device are configured as intermediate base members. Has been.

そして、端部ベース部材と中間部ベース部材の境界部において連続的にパッキンを配置するために、隣接間パッキン材（境界部パッキン材）が設けられる。この隣接間パッキン材は、端部ベース部材に対して取り付けられるベースカバー材に設けられ、ベースカバー材を端部ベース部材に上から取り付けることによって、隣接間パッキン材が境界部に挿入される。   And in order to arrange | position packing continuously in the boundary part of an edge part base member and an intermediate | middle part base member, the adjacent packing material (boundary part packing material) is provided. The adjacent packing material is provided on a base cover material attached to the end base member, and the adjacent packing material is inserted into the boundary portion by attaching the base cover material to the end base member from above.

特開２０１２−００１９６７号公報JP 2012-001967 A

上述した構成のように、境界部において連続的にパッキンを配置するための構成として、端部ベース部材とベースカバー材を別部材で構成する場合には、部品点数が多く、施工現場での施工性や、部品管理の容易性の観点から改良が望まれる。   As in the configuration described above, when the end base member and the base cover material are configured as separate members as a configuration for continuously arranging the packing at the boundary portion, the number of parts is large, and the construction is performed at the construction site. Improvement is desired from the standpoint of performance and ease of component management.

そこで、端部ベース部材に隣接間パッキン材を備える部位を設け、ベースカバー材を省略することが考えられるが、この場合、中間部ベース部材を設置した後に端部ベース部材を取り付ける施工手順となってしまう。つまり、端部ベース部材が先に取付けられてしまうと、隣接間パッキン材を備える部位が邪魔になって、中間部ベース部材を端部ベース部材に重ねるように設置することができないものとなる。   Therefore, it is conceivable that the end base member is provided with a portion having an adjacent packing material and the base cover material is omitted, but in this case, the installation procedure is to attach the end base member after installing the intermediate base member. End up. In other words, if the end base member is attached first, the portion including the adjacent packing material becomes in the way, and the intermediate base member cannot be installed so as to overlap the end base member.

また、この場合、開口部装置の二つの角部に端部ベース部材を設置した上で中間部ベース部材の長さ寸法を設定するといった施工手順が採れなくなり、中間部ベース部材の最適な寸法設定が困難なものとなる。そして、この場合、境界部の隙間が大きくなってしまい、止水性が悪くなってしまうことも懸念される。   Also, in this case, it is not possible to take the construction procedure of setting the length dimension of the intermediate base member after installing the end base members at the two corners of the opening device, and the optimal dimension setting of the intermediate base member Is difficult. In this case, there is a concern that the gap at the boundary portion becomes large and the water stoppage is deteriorated.

そこで、本発明は以上の問題に鑑み、ベース部材を用いた目地構造について新規な技術を提案するものである。   In view of the above problems, the present invention proposes a new technique for joint structures using a base member.

本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。   The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

Next, the intermediate decorative member 60 is attached to the intermediate base member 30 so as to cover the boundary portion between the linear portion of the frame 10 and the outer wall materials 2A, 2B, and 2C from above. Finally, the corner decorative member 70 is attached at the corner 11A of the frame 10 and the construction work is completed.

以下、各部材の構成について実施例を用いて詳細に説明する。なお、以下の説明では、開口部装置のコーナー部に設置される角部端部ベース部材２０Ａと中間部ベース部材３０の継目箇所への適用について説明するが、コーナー部以外の直線部分や、直線部分の終端部分において継目箇所が形成される場合においても、本発明の構成を適用することができる。   Hereafter, the structure of each member is demonstrated in detail using an Example. In addition, although the following description demonstrates application to the joint part of the corner | angular part edge part base member 20A and the intermediate | middle part base member 30 which are installed in the corner part of an opening part apparatus, The configuration of the present invention can be applied even when a seam portion is formed at the end portion of the portion.

まず、図２及び図３に示す角部端部ベース部材２０Ａの構成について説明する。なお、図２（Ａ）（Ｂ）はパッキンが設けられていない状態の角部端部ベース部材２０Ａについて示しており、図２（Ｃ）（Ｄ）、及び、図３（Ａ）（Ｂ）は各種パッキンが設けられた状態の角部端部ベース部材２０Ａについて示している。   First, the configuration of the corner end base member 20A shown in FIGS. 2 and 3 will be described. 2A and 2B show the corner end base member 20A in a state where no packing is provided, and FIGS. 2C and 2D and FIGS. 3A and 3B. Shows the corner end base member 20A in a state where various packings are provided.

角部端部ベース部材２０Ａは、樹脂成形などによって平面視略Ｌ字状に構成される。Ｌ字を構成する互いに直行する辺部分２１ａ・２１ｂには、それぞれ、厚み方向に長孔２２ａ・２２ｂが形設されており、各長孔２２ａ・２２ｂは、辺部分２１ａ・２１ｂの長手方向に長い形状となっている。また、各辺部分２１ａ・２１ｂの端部には、高さを一段低くするようにして端部表面２３ａ・２３ｂが形設されている。また、辺部分２１ａ・２１ｂ上面には、平面視略Ｌ字状のシーリング材境界壁部２５ｄが形設され、図８に示すごとく、シーリング材境界壁部２５ｄと外壁材２Ａの端面２ｍの間にシーリング材５０を充填するための隙間部５が形成されるようになっている。また、辺部分２１ａ・２１ｂの内側には、平面視略Ｌ字状の連続する内側壁部２５ａを構成している。   The corner end base member 20A is formed in a substantially L shape in plan view by resin molding or the like. Long side holes 22a and 22b are formed in the thickness direction in the side portions 21a and 21b that form an L shape, and the long holes 22a and 22b are formed in the longitudinal direction of the side portions 21a and 21b. It has a long shape. Further, end surfaces 23a and 23b are formed at the end portions of the side portions 21a and 21b so as to make the height one step lower. Further, a sealing material boundary wall portion 25d having a substantially L shape in plan view is formed on the upper surfaces of the side portions 21a and 21b, and as shown in FIG. 8, between the sealing material boundary wall portion 25d and the end surface 2m of the outer wall material 2A. A gap 5 for filling the sealing material 50 is formed. Further, inside the side portions 21a and 21b, a continuous inner wall portion 25a having a substantially L shape in plan view is formed.

また、図２及び図３に示すごとく、内側壁部２５ａにおいて、辺部分２１ａ・２１ｂの長手方向の中途部には、それぞれ隣接間パッキン材Ｐ６のパッキン位置切替機構４０が設けられる。パッキン位置切替機構４０は、角部端部ベース部材２０Ａに設けられる支持部２４ａ，２４ｂと、隣接間パッキン材Ｐ６を設けた可動部材４１，４１とを有して構成され、可動部材４１，４１は支持部２４ａ，２４ｂに対する隣接間パッキン材Ｐ６の位置が変更可能なように支持部２４ａ，２４ｂに取付けられる。本実施例では、可動部材４１，４１が支持部２４ａ，２４ｂに対して回動可能に支持されることで、隣接間パッキン材Ｐ６の位置が変更可能となっている。図２（Ｄ）では、詳しくは後述するように、パッキン位置切替機構４０によって、隣接間パッキン材Ｐ６を退避位置に退避させた際の様子を示している。   Moreover, as shown in FIG.2 and FIG.3, in the inner-wall part 25a, the packing position switching mechanism 40 of the packing material P6 between adjacent is provided in the middle part of the side parts 21a * 21b in the longitudinal direction, respectively. The packing position switching mechanism 40 includes support portions 24a and 24b provided on the corner end base member 20A and movable members 41 and 41 provided with an adjacent packing material P6.

In the present embodiment, the movable members 41 and 41 are rotatably supported with respect to the support portions 24a and 24b, so that the position of the adjacent packing material P6 can be changed. FIG. 2D shows a state in which the adjacent packing material P6 is retracted to the retracted position by the packing position switching mechanism 40, as will be described in detail later.

また、図２及び図３に示すごとく、内側壁部２５ａの端部の上面には、高さを一段低くするようにして端部表面２６ａ・２６ｂが形設されている。また、略Ｌ字状の内側壁部２５ａの両端部の下部において、板状の舌片部２８ａ・２８ｂが内側に突設されている。   Further, as shown in FIGS. 2 and 3, end surfaces 26a and 26b are formed on the upper surface of the end portion of the inner wall portion 25a so as to be lowered by one step. In addition, plate-like tongue pieces 28a and 28b project inwardly at lower portions of both end portions of the substantially L-shaped inner wall portion 25a.

また、図３（Ａ）に示すごとく、角部端部ベース部材２０Ａのシーリング材境界壁部２５ｄの外側であって、端部表面２３ａ・２３ｂを除く部位には、辺部分２１ａ・２１ｂ（図２（Ａ）参照）の表面を覆うように外壁裏パッキンＰ１が貼設されている。なお、外壁裏パッキンＰ１は、少なくとも、２２ａ、２２ｂを覆うものであればよい。   Further, as shown in FIG. 3 (A), side portions 21a and 21b (see FIG. 5) are provided on the outside of the sealing material boundary wall 25d of the corner end base member 20A and excluding the end surfaces 23a and 23b. The outer wall back packing P1 is stuck so as to cover the surface of 2 (see (A)). In addition, the outer wall back packing P1 should just cover 22a, 22b at least.

また、図２（Ｃ）に示すごとく、シーリング材境界壁部２５ｄの内側であって、その両端部が二つの舌片部２８ａ・２８ｂに載りかかるようにして、枠側パッキンＰ２が内側壁部２５ａの縦壁面に対して隙間なく貼設されている。各パッキンＰ１・Ｐ２は、いずれも平面視略Ｌ字に構成されている。また、図２（Ａ）に示すごとく、舌片部２８ａ・２８ｂは、内側壁部２５ａから内側へ突出幅Ｈ１だけ突出されおり、枠側パッキンＰ２は舌片部２８ａ・２８ｂから突出幅Ｈ３だけ突出されるようになっている。   Further, as shown in FIG. 2C, the frame side packing P2 is located on the inner side wall portion 25d so that both ends of the sealing material boundary wall portion 25d are placed on the two tongue pieces 28a and 28b. It is affixed with no gap to the vertical wall surface of 25a. Each of the packings P1 and P2 has a substantially L shape in plan view. Further, as shown in FIG. 2A, the tongue pieces 28a and 28b protrude inward from the inner wall portion 25a by the protruding width H1, and the frame side packing P2 has a protruding width H3 from the tongue pieces 28a and 28b. It is designed to protrude.

また、図２（Ａ）（Ｂ）に示される角部端部ベース部材２０Ａの辺部分２１ａの端部に形成される端部表面２３ａと、シーリング材境界壁部２５ｄが立設される基材部２５の端部に形成される端部表面２６ａと、舌片部２８ａの上表面には、図２（Ｃ）（Ｄ）に示すように、各表面の形状に沿うようにして接続部パッキンＰ３が貼設されている。辺部分２１ｂの端部においても同様にして接続部パッキンＰ３が貼設されている。   Moreover, the base material on which the edge part surface 23a formed in the edge part 21a of the corner | angular part edge part base member 20A shown by FIG. 2 (A) (B) and the sealing material boundary wall part 25d are standingly arranged. As shown in FIGS. 2C and 2D, the end portion surface 26a formed at the end portion of the portion 25 and the upper surface of the tongue piece portion 28a are connected to the connection portion packing so as to follow the shape of each surface. P3 is affixed. Similarly, the connection portion packing P3 is attached to the end portion of the side portion 21b.

以上のようにしてパッキンＰ１・Ｐ２・Ｐ３、及び、隣接間パッキン材Ｐ６を備えた角部端部ベース部材２０Ａが構成され、各パッキンＰ１・Ｐ２・Ｐ３・Ｐ６が設けられた状態で、施工現場に提供されることとしている。   As described above, the corner end portion base member 20A including the packings P1, P2, and P3 and the adjacent packing material P6 is configured, and the construction is performed with the packings P1, P2, P3, and P6 provided. It is supposed to be provided on site.

また、図３（Ｂ）に示すように、辺部分２１ａ・２１ｂの下側から突条部２１ｍ・２１ｎが下方に突設される構成とてもよい。これにより、辺部分２１ａ・２１ｂの下面２１ｘを、突条部２１ｍ・２１ｎの突出量に相当する分だけ底上げすることができ、この底上げ箇所に、例えば、サッシの取り付け片１０ｍを配置することが可能となる。そして、辺部分２１ａ・２１ｂの下面２１ｘをサッシの取り付け片１０ｍに当接させるとともに、取り付け片１０ｍが無い箇所において、突条部２１ｍ・２１ｎを胴縁などの躯体面１０ｘに当接させることで、角部端部ベース部材２０Ａにぐらつきが生じないように固定することが可能となる。この構成によれば、サッシの取り付け片１０ｍの出幅寸法１０ｎが施工箇所において異なる場合であっても、適宜対応することが可能となる。   Moreover, as shown to FIG. 3 (B), the structure by which the protrusion part 21m * 21n protrudes below from side part 21a * 21b very good is very good. Accordingly, the lower surface 21x of the side portions 21a and 21b can be raised by an amount corresponding to the protruding amount of the protruding portions 21m and 21n, and for example, a sash attachment piece 10m can be disposed at the raised portion. It becomes possible. Then, the lower surfaces 21x of the side portions 21a and 21b are brought into contact with the sash attachment piece 10m, and the protrusions 21m and 21n are brought into contact with the housing surface 10x such as the trunk edge in a place where the attachment piece 10m is not provided. The corner end base member 20A can be fixed so as not to wobble. According to this configuration, even if the projecting width 10n of the sash attachment piece 10m is different at the construction site, it is possible to cope with it appropriately.

Thus, as shown in FIG. 5, after the engaging piece portions 61a and 61b of the intermediate decorative member 60 are fitted between the frame side vertical wall portion 33 and the outer wall material side vertical wall portion 34, the ridge portion 62a. -62b (FIG. 7) and the protrusions 33a and 34a engage, so that the intermediate decorative member 60 can be prevented from falling off.

また、図４及び図５に示すごとく、枠側設置面部３１と枠側縦壁部３３に接するように、断面方形の棒状の枠側パッキンＰ４が貼設されている。また、図４に示すごとく、枠側設置面部３１は、枠側縦壁部３３から左側へ突出幅Ｈ２だけ突出されおり、枠側パッキンＰ４は枠側設置面部３１から突出幅Ｈ４だけ突出されるようになっている。   Moreover, as shown in FIG.4 and FIG.5, the rod-shaped frame side packing P4 of a square cross section is stuck so that the frame side installation surface part 31 and the frame side vertical wall part 33 may be contact | connected. As shown in FIG. 4, the frame-side installation surface portion 31 protrudes from the frame-side vertical wall portion 33 to the left by the protruding width H2, and the frame-side packing P4 protrudes from the frame-side installation surface portion 31 by the protruding width H4. It is like that.

また、図６に示すごとく、枠側パッキンＰ４は、その端面が角部端部ベース部材２０Ａの枠側パッキンＰ２の端面に当接し得る構成となっており、両枠側パッキンＰ２・Ｐ４によって連続した一連のパッキンが構成されるようになっている。   Further, as shown in FIG. 6, the frame side packing P4 has a configuration in which the end surface thereof can abut against the end surface of the frame side packing P2 of the corner end portion base member 20A, and is continuous by both frame side packings P2 and P4. A series of packings are configured.

また、図４及び図５に示すごとく、外壁材側設置面部３２の右端部の上面には、断面方形の棒状の外壁裏パッキンＰ５が貼設されている。この外壁裏パッキンＰ５は、上側から外壁材２Ａが押し付けられることで圧縮し、スペーサー材３と外壁材２Ａの間の止水性が確保されるようになっている。   Moreover, as shown in FIG.4 and FIG.5, on the upper surface of the right end part of the outer wall material side installation surface part 32, the rod-shaped outer wall back packing P5 with a square cross section is stuck. The outer wall back packing P5 is compressed when the outer wall material 2A is pressed from above, and water-stopping between the spacer material 3 and the outer wall material 2A is ensured.

また、図５に示すごとく、外壁材２Ａと外壁材側縦壁部３４と第二の水平部３６で囲まれて、溝状に形成される隙間部５には、シーリング材５０が充填される。なお、隙間部５の幅は、シーリング材５０のはみ出しが抑えやすく、外壁材２Ａ表面の養生テープなどによるマスキングの作業を省いて仕上げを容易に可能とする観点から、５ｍｍ程度の幅に設定することが好ましい。   Further, as shown in FIG. 5, the sealing material 50 is filled in the gap portion 5 that is surrounded by the outer wall material 2 </ b> A, the outer wall material-side vertical wall portion 34, and the second horizontal portion 36 and is formed in a groove shape. . The width of the gap 5 is set to a width of about 5 mm from the viewpoint that it is easy to prevent the sealing material 50 from protruding and masking work using a curing tape or the like on the surface of the outer wall material 2A can be easily performed. It is preferable.

また、図５に示す隙間部５の目地幅の５ｍｍの設定について、シーリング材５０を用いた通常の湿式目地の場合では、一般的に目地幅を１０ｍｍ以上とすることが要求されることになるが、本実施例では、このシーリング材５０は中間部ベース部材３０による乾式目地を形成した上での補強的なものであるため、一般的な湿式目地において要求される目地幅を確保する必要がない。   Further, regarding the setting of the joint width of 5 mm of the gap portion 5 shown in FIG. 5, in the case of a normal wet joint using the sealing material 50, the joint width is generally required to be 10 mm or more. However, in this embodiment, since the sealing material 50 is a reinforcing material after forming a dry joint by the intermediate base member 30, it is necessary to secure a joint width required in a general wet joint. Absent.

さらに、本実施例では、隙間部５を止水するためにシーリング材５０を充填する構成としたが、このほか、隙間部５に乾式のパッキンが配置される構成とすることとしてもよい。これによれば、後述する施工作業において、シーリング材５０の充填作業が不要な構成が実現される。なお、シーリング材については、外壁の目地を埋めるものとして広く知られている市販のものを使用することができる。また、パッキンについては、例えば、ＥＰＤＭ（エチレン−プロピレン−ジエンゴム）などからなる市販の素材を使用することができる。   Furthermore, in the present embodiment, the sealing material 50 is filled in order to stop the gap 5, but in addition to this, a dry packing may be arranged in the gap 5. According to this, the structure which does not need the filling operation | work of the sealing material 50 in the construction operation mentioned later is implement | achieved. In addition, about the sealing material, the commercially available thing widely known as what fills the joint of an outer wall can be used. Moreover, about packing, the commercially available raw material which consists of EPDM (ethylene-propylene-diene rubber) etc. can be used, for example.

また、図６に示すごとく、中間部ベース部材３０の長手方向の端部３０Ａは、角部端部ベース部材２０Ａの接続部パッキンＰ３の部位に覆い被せられるようになっており、これにより、角部端部ベース部材２０Ａの表側の面（表面２３ａ・２６ａ、舌片部２８ａの表面）と、中間部ベース部材３０の裏側の面との間の隙間が、接続部パッキンＰ３によって塞がれるようになっている。   Further, as shown in FIG. 6, the end portion 30A in the longitudinal direction of the intermediate base member 30 is configured to cover the portion of the connecting portion packing P3 of the corner end base member 20A. The gap between the front side surface (surface 23a, 26a, the surface of the tongue piece portion 28a) of the end portion base member 20A and the back side surface of the intermediate base member 30 is blocked by the connecting portion packing P3. It has become.

また、中間部ベース部材３０の端部３０Ａが、角部端部ベース部材２０Ａの接続部パッキンＰ３の部位、及び、パッキンＰ７に対し隙間無く覆い被せられるようにするために、角部端部ベース部材２０Ａの接続部パッキンＰ３の表側に形成される凹凸形状は、図４に示す中間部ベース部材３０の断面裏側に形成される凹凸形状に沿う形状とすることが好ましい。   In addition, in order to cover the end portion 30A of the intermediate base member 30 with the gap portion of the connecting portion packing P3 of the corner end portion base member 20A and the packing P7 without gaps, The uneven shape formed on the front side of the connection portion packing P3 of the member 20A is preferably a shape along the uneven shape formed on the back side of the cross section of the intermediate base member 30 shown in FIG.

また、図６に示すごとく、角部端部ベース部材２０Ａにおいて、中間部ベース部材３０側に向けて突出し、中間部ベース部材３０の溝空間３５ａ（図１１（Ｃ）参照）に入り込むように突出するパッキンＰ７を設けることとしてもよい。   Further, as shown in FIG. 6, the corner end base member 20 </ b> A protrudes toward the intermediate base member 30 and protrudes into the groove space 35 a (see FIG. 11C) of the intermediate base member 30. It is good also as providing packing P7 to do.

これにより、角部端部ベース部材２０Ａと中間部ベース部材３０の間に発生する隙間を埋めることが可能となり、当該隙間における止水性を高めることができる。   Thereby, it becomes possible to fill the gap generated between the corner end base member 20A and the intermediate base member 30, and the water stoppage in the gap can be increased.

次に、図７に示す中間部化粧部材６０の構成ついて説明する。
中間部化粧部材６０は、長尺の板状部材であって、板面部６２の裏面側において、二列の係合片部６１ａ・６１ｂが長手方向に突設される構成としている。また、図４、図５、図７に示すごとく、この係合片部６１ａ・６１ｂは、中間部ベース部材３０の枠側縦壁部３３と外壁材側縦壁部３４の間に挿入されるとともに、係合片部６１ａ・６１ｂの側面に形設された突条部６２ａ・６２ｂが突条部３３ａ・３４ａの下方まで移動される。このようにして、中間部化粧部材６０が中間部ベース部材３０に嵌着される。 Next, the configuration of the intermediate decorative member 60 shown in FIG. 7 will be described.
The intermediate decorative member 60 is a long plate-like member, and has two rows of engaging piece portions 61 a and 61 b protruding in the longitudinal direction on the back surface side of the plate surface portion 62. Further, as shown in FIGS. 4, 5, and 7, the engaging piece portions 61 a and 61 b are inserted between the frame-side vertical wall portion 33 and the outer wall material-side vertical wall portion 34 of the intermediate base member 30. At the same time, the protrusions 62a and 62b formed on the side surfaces of the engagement pieces 61a and 61b are moved to below the protrusions 33a and 34a. In this manner, the intermediate decorative member 60 is fitted to the intermediate base member 30.

また、図５に示すごとく、中間部化粧部材６０の板面部６２は、中間部ベース部材３０に嵌着された状態において、左側端部が中間部ベース部材３０の枠側縦壁部３３よりも枠１０側に突出し、右側端部が外壁材２Ａの外装面端部に覆い被さるように突出することとしている。これにより、枠側パッキンＰ４と、シーリング材５０が中間部化粧部材６０によって覆い隠されることとなっている。特に、シーリング材５０については、中間部化粧部材６０によって完全に隠されることとすることで、シーリング材５０が外壁材２Ａの外装面にはみ出している場合には、このはみ出したシーリング材５０を覆い隠すことができ、仕上げ作業の簡略化を図ることができる。   Further, as shown in FIG. 5, the plate surface portion 62 of the intermediate decorative member 60 has a left end that is more than the frame-side vertical wall portion 33 of the intermediate base member 30 in a state of being fitted to the intermediate base member 30. It protrudes to the frame 10 side and protrudes so that the right side end portion covers the exterior surface end portion of the outer wall material 2A. As a result, the frame side packing P4 and the sealing material 50 are covered with the intermediate decorative member 60. In particular, the sealing material 50 is completely hidden by the intermediate decorative member 60, so that when the sealing material 50 protrudes from the exterior surface of the outer wall material 2A, the protruding sealing material 50 is covered. It can be hidden and the finishing work can be simplified.

また、図５に示すごとく、中間部化粧部材６０によってシーリング材５０への紫外線照射を防ぐことが可能となり、紫外線が照射されることに伴って発生するヒビ割れなどの劣化を防止することができる。   Further, as shown in FIG. 5, the intermediate decorative member 60 can prevent the sealing material 50 from being irradiated with ultraviolet rays, and can prevent deterioration such as cracks caused by the irradiation of ultraviolet rays. .

次に、図８に示す角部化粧部材７０について説明する。
この角部化粧部材７０は、平面視略Ｌ字状のカバー板面７１と、カバー板面７１の裏側に突設される複数の係合突部７２と、を有して構成される。係合突部７２は、角部端部ベース部材２０Ａにおいて上方に突設される複数の係合突部２７と係合されることにより、角部化粧部材７０を角部端部ベース部材２０Ａに嵌着させることができる。 Next, the corner decorative member 70 shown in FIG. 8 will be described.
The corner decorative member 70 includes a substantially L-shaped cover plate surface 71 in plan view and a plurality of engaging protrusions 72 protruding from the back side of the cover plate surface 71. The engagement protrusion 72 is engaged with the plurality of engagement protrusions 27 protruding upward at the corner end base member 20A, thereby turning the corner decorative member 70 into the corner end base member 20A. Can be fitted.

そして、角部化粧部材７０を角部端部ベース部材２０Ａに嵌着させると、角部化粧部材７０の両端部が二本の中間部化粧部材６０のそれぞれの端部の上に覆い被さる。これにより、角部化粧部材７０と中間部化粧部材６０によって隙間の無い一連の外観表面を形成することができる。   Then, when the corner decorative member 70 is fitted to the corner end base member 20 </ b> A, both ends of the corner decorative member 70 cover the respective end portions of the two intermediate decorative members 60. Thereby, a series of appearance surfaces without gaps can be formed by the corner decorative member 70 and the intermediate decorative member 60.

また、嵌着後において、カバー板面７１を押し上げることで、適宜、角部化粧部材７０を角部端部ベース部材２０Ａから取り外すことができる。これにより、角部化粧部材７０や中間部化粧部材６０を取り外して、メンテナンスなどを行うことも可能となる。   Moreover, the corner | angular part decorative member 70 can be suitably removed from the corner | angular part base part 20A by pushing up the cover board surface 71 after fitting. Thereby, it becomes possible to remove the corner | angular part decorative member 70 and the intermediate | middle part decorative member 60, and to perform a maintenance.

次に、以上の構成の各部材を使用した施工手順について詳細に説明する。
図１の上列左から順に説明すると、まず、図示せぬ躯体側に開口部装置１の枠１０が取り付けられた状態となっている。この枠１０は方形状に構成されており、各角部１１Ａ・１１Ｂにおいて、それぞれ角部端部ベース部材２０Ａ・２０Ｂが押し当てられ、この角部端部ベース部材２０Ａ・２０Ｂが躯体側に固定される。 Next, the construction procedure using each member having the above configuration will be described in detail.
If it demonstrates sequentially from the upper left of FIG. 1, it will be in the state to which the frame 10 of the opening part apparatus 1 was first attached to the housing side which is not shown in figure. The frame 10 is configured in a square shape, and the corner end base members 20A and 20B are pressed against the corner portions 11A and 11B, respectively, and the corner end base members 20A and 20B are fixed to the housing side. Is done.

ここで、図９（Ａ）に示すごとく、角部１１Ａにおける角部端部ベース部材２０Ａの固定について、まずは、矢印Ｆ１の方向に角部端部ベース部材２０Ａを開口部装置の枠１０に対して押し付けた状態とし、外壁裏パッキンＰ１の端を一時的に剥がし、長孔２２ｂを通して固定具２９ｂを躯体側に仮に固定する。これにより、図において矢印Ｙ方向における角部端部ベース部材２０Ａの位置決めが行われる。   Here, as shown in FIG. 9 (A), for fixing the corner end base member 20A at the corner 11A, first, the corner end base member 20A is moved with respect to the frame 10 of the opening device in the direction of the arrow F1. The end of the outer wall back packing P1 is temporarily peeled off, and the fixing tool 29b is temporarily fixed to the housing through the long hole 22b. Thereby, positioning of the corner | angular part edge part base member 20A in the arrow Y direction in a figure is performed.

また、図９（Ｂ）に示すごとく、矢印Ｆ２の方向に角部端部ベース部材２０Ａを枠１０に対して押し付けた状態とし、外壁裏パッキンＰ１の端を一時的に剥がし、長孔２２ａを通して固定具２９ａを躯体側に仮に固定する。ここでの矢印Ｆ２方向の角部端部ベース部材２０Ａの押し付けは、仮に留め付けられた固定具２９ｂが長孔２２ｂを移動することで可能となる。   Further, as shown in FIG. 9B, the corner end base member 20A is pressed against the frame 10 in the direction of arrow F2, the end of the outer wall back packing P1 is temporarily peeled off, and the long hole 22a is passed through. The fixing tool 29a is temporarily fixed to the housing side. The pressing of the corner end base member 20A in the direction of the arrow F2 here becomes possible when the fixture 29b temporarily fastened moves through the long hole 22b.

そして、固定具２９ａを完全に固定することで、図において矢印Ｘ方向における角部端部ベース部材２０Ａの位置決め固定が行われ、最後に固定具２９ｂを完全に固定することで、角部端部ベース部材２０Ａの留め付けが完了する。なお、一時的に剥がされた外壁裏パッキンＰ１の部位は、その裏面の接着面によって元の貼設された状態に戻される。   Then, by fixing the fixing tool 29a completely, the corner end base member 20A is positioned and fixed in the direction of the arrow X in the figure, and finally the fixing tool 29b is completely fixed, so that the end of the corner part is fixed. Fastening of the base member 20A is completed. In addition, the site | part of the outer wall back packing P1 peeled off temporarily is returned to the state affixed by the adhesive surface of the back surface.

また、角部端部ベース部材２０Ａが止め付けられた状態では、枠側パッキンＰ２が圧縮されることで、枠１０と角部端部ベース部材２０Ａの間の止水性が確保される。この際、舌片部２８ａ・２８ｂが枠１０に当接することで、枠側パッキンＰ２はその突出幅Ｈ３（図２参照）の分だけ圧縮することになる。これにより、枠側パッキンＰ２の圧縮量は一定の値となって、施工によるばらつきの発生が抑えられることとなる。   In addition, in a state where the corner end base member 20A is stopped, the frame side packing P2 is compressed, so that the water stoppage between the frame 10 and the corner end base member 20A is ensured. At this time, when the tongue pieces 28a and 28b abut against the frame 10, the frame side packing P2 is compressed by the protrusion width H3 (see FIG. 2). Thereby, the compression amount of the frame side packing P2 becomes a constant value, and the occurrence of variation due to construction is suppressed.

次に、図１に示すごとく、角部端部ベース部材２０Ａ・２０Ｂの間のスペースに対し、中間部ベース部材３０が取り付けられる。中間部ベース部材３０の長さは、スペースの寸法に合うように切断加工によって適宜調整される。   Next, as shown in FIG. 1, the intermediate base member 30 is attached to the space between the corner end base members 20 </ b> A and 20 </ b> B. The length of the intermediate base member 30 is appropriately adjusted by cutting so as to match the size of the space.

また、この中間部ベース部材３０は、図５に示すごとく、枠側パッキンＰ４を開口部装置の枠１０の側面に対して押し付けるとともに、枠側設置面部３１を枠１０の側面１０ａに当接させた状態とし、スペーサー材３の上面に対しビス４にて固定される。   Further, as shown in FIG. 5, the intermediate base member 30 presses the frame side packing P4 against the side surface of the frame 10 of the opening device, and causes the frame side installation surface portion 31 to contact the side surface 10a of the frame 10. And fixed to the upper surface of the spacer material 3 with screws 4.

また、図５に示すごとく、中間部ベース部材３０が止め付けられた状態では、枠側パッキンＰ４が圧縮されることで、枠１０と中間部ベース部材３０間の止水性が確保される。この際、枠側設置面部３１が枠１０に当接してストップすることで、枠側パッキンＰ４はその突出幅Ｈ４（図４（Ａ）参照）の分だけ圧縮することになる。これにより、枠側パッキンＰ４の圧縮量は一定の値となって、施工によるばらつきの発生が抑えられることとなる。   Further, as shown in FIG. 5, in a state where the intermediate portion base member 30 is fixed, the frame side packing P <b> 4 is compressed, thereby ensuring the water stoppage between the frame 10 and the intermediate portion base member 30. At this time, when the frame side installation surface portion 31 comes into contact with the frame 10 and stops, the frame side packing P4 is compressed by the protrusion width H4 (see FIG. 4A). Thereby, the compression amount of the frame side packing P4 becomes a constant value, and the occurrence of variations due to construction is suppressed.

また、図１０（Ａ）に示すごとく、中間部ベース部材３０の端部３０Ａは、角部端部ベース部材２０Ａの接続部パッキンＰ３の部位に覆い被せられ、角部端部ベース部材２０Ａの表側の面（図２参照：表面２３ａ・２６ａ、舌片部２８ａの表面）と、中間部ベース部材３０の裏側の面との間の隙間が接続部パッキンＰ３によって塞がれる。   Further, as shown in FIG. 10A, the end 30A of the intermediate base member 30 is covered with the connection packing P3 portion of the corner end base member 20A, and the front side of the corner end base member 20A is covered. (See FIG. 2: the surfaces 23a and 26a, the surface of the tongue piece 28a) and the gap on the back side of the intermediate base member 30 are closed by the connecting portion packing P3.

また、図１０（Ａ）に示すごとく、中間部ベース部材３０の端部３０Ａを角部端部ベース部材２０Ａに接続する際には、パッキン位置切替機構４０の可動部材４１を上方に向けるようにして、隣接間パッキン材Ｐ６を退避位置に退避させる。これにより、中間部ベース部材３０が可動部材４１と干渉せずに、角部端部ベース部材２０Ａに対して接続することができる。   Further, as shown in FIG. 10A, when the end 30A of the intermediate base member 30 is connected to the corner end base member 20A, the movable member 41 of the packing position switching mechanism 40 is directed upward. Thus, the adjacent packing material P6 is retracted to the retracted position. Accordingly, the intermediate base member 30 can be connected to the corner end base member 20A without interfering with the movable member 41.

次いで、図１０（Ｂ）に示すごとく可動部材４１を回動させ、図１０（Ｃ）に示すように、隣接間パッキン材Ｐ６をパッキン材間位置に設定することで、隣接間パッキン材Ｐ６をパッキン材間位置４４（継目箇所）に埋め込ませる。本実施例では、図１１（Ａ）に示すごとく、可動部材４１の二箇所に設けた係合箇所４１ｂ，４１ｃを、角部端部ベース部材２０Ａの二箇所に設けた係合箇所２５ｂ，２５ｃに係合させることにより、図１０（Ｃ）、図１１（Ｂ）に示すごとく、パッキンＰ２・Ｐ４により生じる弾性復帰力Ｍに抗して、可動部材４１をパッキン材間位置に保持することができる。なお、パッキンＰ２・Ｐ４の間の境界部４４（パッキン材間位置）に隙間がなく、パッキンＰ２・Ｐ４同士が略接している場合であっても、両者の間に隣接間パッキン材Ｐ６が配置されることで、微小な隙間を塞ぐことができ、より止水性を高めることができる。   Next, the movable member 41 is rotated as shown in FIG. 10B, and the adjacent packing material P6 is set to the position between the packing materials P6 as shown in FIG. It is made to embed in packing material position 44 (seam part). In this embodiment, as shown in FIG. 11 (A), engagement locations 41b and 41c provided at two locations on the movable member 41 are replaced with engagement locations 25b and 25c provided at two locations on the corner end base member 20A. 10 (C) and 11 (B), the movable member 41 can be held at the position between the packing materials against the elastic return force M generated by the packings P2 and P4. it can. In addition, even when there is no gap at the boundary portion 44 (the position between the packing materials) between the packings P2 and P4 and the packings P2 and P4 are substantially in contact with each other, the adjacent packing material P6 is disposed between them. By doing so, a minute gap can be closed and the water stoppage can be further increased.
