Description

【０００１】
【発明の属する技術分野】
この発明は、現場施工における取付作業が容易で、軒裏の換気も良好な軒天井取付構造に関する。
【０００２】
【先行技術】
図３は、従来の軒天井取付構造の縦断面図を示すものである。
従来の軒天井取付構造は、軒裏に軒天井110を形成するために、この軒天井110を建物躯体140等に固定するための複数の下地材120を使用していた。具体的には、下地材120は、建物躯体140の外周表面に沿って、建物躯体140である壁パネル141や軒先170の屋根パネル171等に固定される長尺状の長尺下地材121と、建物躯体140の外方に向かって延びて長尺下地材121間を連結する短尺状の短尺下地材122とを備えていた。そして、この短尺下地材122の下面に薄板状の軒天井110を釘等の締結部材123を介して固定していた。
【０００３】
なお、外壁となる建物躯体140は、特に図示しないが、木質からなり四角枠状の枠材及びその枠内を塞ぐ面材からなる壁パネル141から形成されているものである。そして、この壁パネル141の外側表面には、横方向に沿って木質からなる長尺状の胴縁160が固定され、この胴縁160の外側にセラミック等からなり表面に凹凸模様を有する外壁化粧材150が固定されていた。
【０００４】
なお、この軒天井110に関する技術を、日本特許情報機構（ＪＡＰＩＯ）の先行技術調査（パトリス）の利用により、以下の検索式で昭和５５年以後の特許出願、実用新案登録出願を調査した。
検索式：Ｅ０４Ｂ０５／６０Ｃ
その結果、特許出願８０余件、実用新案登録出願１８０余件を抽出した。
その中で関連する技術としては、特開平２−３０４１５８号に記載された技術のように、軒天井を固定するために下地材を使用するもので、その下地材の固定位置を工夫したものや、特公平６−５００１３号に記載された技術のように、軒先側にのみ木質からなる下地材を利用して軒天井の一端を固定するが、建物躯体側には、軒天井の他端を挟み込むような軒天井支持具を使用するもの等がある。
【０００５】
【発明が解決しようとする課題】
しかし、上記した図３に示すものや、特開平２−３０４１５８号や、特公平６−５００１３号に示す従来の軒天井取付構造は、いずれも、下地材や軒天井支持具を固定した後に軒天井をそれらに固定するため、軒天井を固定した後、軒天井の下面が僅かに傾斜していた場合、その傾斜角度を水平に戻すためには、軒天井に加えて、下地材や軒天井支持具等を取り外さなければならず、水平のレベル調整が容易ではないという第一の問題点があった。
【０００６】
また、複数の種類の下地材を多数、組まなければならず、現場施工において、大変、手間がかかるという第二の問題点があった。
そこで、請求項１記載の発明は、上記した従来の技術の有する第一及び第二の問題点に鑑みてなされたものであり、その目的とするところは、下地材の使用数を減らすことができるとともに、軒天井の水平レベルの調整を容易にすることができて、現場施工における取付作業を簡単にすることができる軒天井取付構造を提供しようとするものである。
【０００７】
これに加え、この請求項１記載の発明は、換気口を形成したことにより、軒裏の換気を容易にすることができる軒天井取付構造を提供しようとするものである。
【０００８】
【０００９】
請求項２記載の発明は、軒天井の水平レベルの調整を容易にすることができる軒天井取付構造の取付方法を提供しようとするものである。
なお、上記の課題を解決する技術は、上述した日本特許情報機構（ＪＡＰＩＯ）の先行技術調査（パトリス）によっては、発見できなかった。
【００１０】
【課題を解決するための手段】
本発明は、上記した目的を達成するためのものである。
請求項１記載の発明は、軒裏に形成される軒天井(10)の取付構造であって、軒天井(10)は、縦断面形状が略Ｌ字状であって、軒先(70)と建物躯体(40)との間を横方向に渡した平板状の軒天井本体(20)と、この軒天井本体(20)の建物躯体(40)側から下方に向かって延びて、軒天井本体(20)よりも下方の建物躯体(40)に固定可能な延設部(30)とを備え、延設部(30)には、軒裏換気のために上下方向に貫通する換気口(34)が所定間隔で複数個形成されるとともに、延設部(30)は、延設用締結部材(48)により建物躯体(40)となる壁パネル(41)の外側表面側に固定され、軒天井本体 (20) との間に隙間をあけた状態で壁パネル(41)の外側表面側に胴縁(60)を介して固定された外壁化粧材(50)の上部で前記延設部(30)を固定した延設用締結部材(48)が覆い隠されるように構成され、前記軒裏と外部とが前記換気口 (3 4) および軒天井本体 (20) と外壁化粧材 (50) の上部との間の隙間を介して連通されていることを特徴とする。

【００１３】
【００１４】
【００１５】
また、本発明において、延設部(30)には、上下方向に貫通する換気口(34)を形成し、さらに軒天井本体 (20) と外壁化粧材 (50) の上部との間に隙間をあけて壁パネル (41) の外側表面側に外壁化粧材 (50) を固定しているから、軒天井(10)を形成した後も、この換気口(34)および軒天井本体 (20) と外壁化粧材 (50) の上部との間の隙間を介して、軒裏と外部との間で、空気が自由に移動することができ、軒裏の換気を良好なものにすることができる。

【００１９】
本発明に係る軒天井取付構造の取付方法は、先ず、最初に軒先(70)の下面側に下地材(45)を固定する。
次に、その固定した下地材(45)の下面に、軒天井本体(20)の反建物躯体(40)側の端部上面を固定する。これにより、軒天井本体(20)の反建物躯体(40)側のみが固定され、その反対側の建物躯体(40)側の端部は自由端となる。
【００２０】
次に、軒天井本体(20)の反建物躯体(40)側の端部のみを固定した状態で、軒天井本体(20)の建物躯体(40)側の端部を、上下方向に移動して軒天井本体(20)の取付位置を決定する。
軒天井本体(20)の軒先(70)側の端部のみを固定した状態であるため、軒天井本体(20)の全体を持つ必要がなく、延設部(30)のみを上下方向に移動するだけで簡単に取付位置を決定することができる。
【００２１】
次に、軒天井本体(20)の建物躯体(40)側の端部の取付位置を決定した後、延設部(30)を延設用締結部材(48)により建物躯体(40)となる壁パネル(41)の外側表面側に固定する。その後、壁パネル (41) の外側表面に胴縁 (60) を固定し、その外側表面に外壁化粧材 (50) を、その上部と軒天井本体 (20) との間に隙間をあけて固定する。これにより、軒天井(10)の取付作業が終了する。

【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて、更に詳しく説明する。
図１及び図２は、本発明の第一の実施の形態であって、図１は軒天井取付構造の縦断面図、図２は軒天井の一部外観斜視図をそれぞれ示すものである。
まず、本実施の形態の構成について説明する。
【００２３】
本実施の形態に係る軒天井取付構造は、軒裏に形成される軒天井10の取付構造である。この軒天井10は、縦断面形状が略Ｌ字状であって、締結部材46(47,48) を介して、建物躯体40及び軒先70に固定されている。具体的には、軒天井10は、軒先70と建物躯体40との間を横方向に渡した平板状の軒天井本体20と、この軒天井本体20の建物躯体40側から下方に向かって延びて、軒天井本体20よりも下方の建物躯体40に固定可能な延設部30とを備えている。

【００２６】
次に、その固定した下地材45の下面に、軒天井本体20の反建物躯体40側の端部上面を下地用締結部材47を介して固定する。これにより、軒天井本体20の反建物躯体40側のみが固定され、その反対側に位置する軒天井本体20の建物躯体40側の端部は自由端となる。
次に、軒天井本体20の反建物躯体40側の端部のみを固定した状態で、軒天井本体20の建物躯体40側の端部を、上下方向に移動して軒天井本体20の取付位置を決定する。その際、軒天井本体20の軒先70側の端部のみを固定した状態であるため、取付作業者は、軒天井本体20の全体を手等で持つ必要がなく、延設部30のみを上下方向に移動するだけで簡単に取付位置を決定することができる。
【００２７】
次に、軒天井本体20の建物躯体40側の端部の取付位置を決定した後、延設部30を延設用締結部材48により建物躯体40に固定する。これにより、軒天井10が軒裏に固定された状態となる。
その後、壁パネル41の外側表面に胴縁60を固定し、その外側表面に外壁化粧材50を、その上部と軒天井本体 20 との間に隙間をあけて固定する。
この外壁化粧材50の上部により、延設用締結部材48は覆い隠され、外部からは見えないように隠される。これにより、軒天井取付構造の取付作業が終了する。
【００２８】
次に、上述した実施の形態の作用及び効果について説明する。
本実施の形態は、延設部30が軒天井本体20の建物躯体40側から下方に延びて、軒天井本体20よりも下方の建物躯体40に固定可能に形成されている。このため、軒天井本体20の軒先70側の端部のみを軒裏に固定した状態で、軒天井本体20の建物躯体40側の端部を上下方向に移動させて、軒天井本体20の水平状態を確認しながら、軒天井本体20の取付位置を決定することができる。そして、軒天井本体20の取付位置を決定した後、延設部30を建物躯体40に固定することができる。これにより、軒天井本体20の水平レベルの調整を容易にすることができ、現場施工における取付作業を簡単にすることができる。
【００２９】
また、軒天井本体20の建物躯体40側の端部は、直接、延設部30により建物躯体40に固定するため、軒天井本体20を建物躯体40に固定するための下地材を組む必要がない。これにより、軒天井本体20の取付作業に使用する部材を減少させることができるとともに、作業自体を簡単なものにすることができる。
また、本実施の形態において、保持部32には、上下方向に貫通する換気口34を形成している。このため、軒天井10を形成した後も、この換気口34および軒天井本体 20 と外壁化粧材 50 の上部との間の隙間を介して、軒裏と外部との間で、空気が自由に移動することができ、軒裏の換気を良好なものにすることができる。

First, the configuration of the present embodiment will be described.
[0023]
The eaves ceiling mounting structure according to the present embodiment is an eave ceiling 10 mounting structure formed on the back of the eaves. The eaves ceiling 10 has a substantially L-shaped vertical cross-sectional shape, and is fixed to the building frame 40 and eaves tip 70 via fastening members 46 (47, 48). Specifically, the eaves ceiling 10 extends downward from the eaves ceiling body 20 side of the flat eaves ceiling body 20 across the eaves 70 and the building housing 40, and the eaves ceiling body 20 from the building housing 40 side. And an extending portion 30 that can be fixed to the building frame 40 below the eaves ceiling main body 20.
Then, the eaves tip 70 side of the eaves ceiling body 20 is fixed to a base material 45 made of a long wooden material fixed to the lower surface of the roof panel 71 via a base fastening member 47. The extending portion 30 is fixed to the building frame 40 by an extending fastening member 48 from the outside.
[0024]
The building housing 40 serving as the outer wall is formed from a wall frame 41 made of a wooden frame material and a frame material made of a square frame, and a face material closing the inside of the frame, although not particularly shown. A long trunk edge 60 made of wood is fixed along the lateral direction on the outer surface of the wall panel 41, and the outer wall is made of ceramic or the like and has an uneven pattern on the surface. The decorative material 50 is fixed. As is apparent from FIG. 1, the outer wall decorative material 50 is fixed with a gap between the upper part and the eaves ceiling main body 20, and is fastened for extending the rim portion 30 to the building frame 40. The member 48 is obscured.
[0025]
As shown in FIG. 2, a plurality of ventilation openings 34 penetrating in the vertical direction for eaves back ventilation are formed in the extended portion 30 of the eaves ceiling 10 at predetermined intervals. The ventilation port 34 communicates with a gap between the eaves ceiling main body 20 and the upper portion of the outer wall decorative material 50 , whereby the eaves back and the outside communicate with each other to ventilate the back of the eaves.
Next, a mounting method of the eaves ceiling mounting structure will be described.
In the mounting method of the eaves ceiling mounting structure according to the present embodiment, first of all, a long base material 45 made of wood is not particularly shown on the lower surface side of the roof panel 71 of the eaves 70, but a fastening member such as a screw is not shown. Fix it.
[0026]
Next, the upper surface of the end of the eaves ceiling main body 20 on the side opposite to the building housing 40 is fixed to the lower surface of the fixed base material 45 through the base fastening member 47. Thereby, only the anti-building housing 40 side of the eaves ceiling main body 20 is fixed, and the end of the eaves ceiling main body 20 located on the opposite side to the building housing 40 side is a free end.
Next, in the state where only the end of the eaves ceiling body 20 on the side opposite to the building frame 40 is fixed, the end of the eaves ceiling body 20 on the side of the building frame 40 is moved up and down to install the eaves ceiling body 20 To decide. At that time, since only the end of the eaves ceiling body 20 on the eaves 70 side is fixed, the installation operator does not need to hold the entire eaves ceiling body 20 by hand, and only the extension part 30 is moved up and down. The mounting position can be easily determined simply by moving in the direction.
[0027]
Next, after determining the attachment position of the end of the eaves ceiling main body 20 on the building housing 40 side, the extending portion 30 is fixed to the building housing 40 by the extending fastening member 48. As a result, the eaves ceiling 10 is fixed to the back of the eaves.
Thereafter, the trunk edge 60 is fixed to the outer surface of the wall panel 41, and the outer wall decorative material 50 is fixed to the outer surface of the wall panel 41 with a gap between the upper portion and the eaves ceiling main body 20 .
The upper portion of the outer wall decorative material 50 covers and hides the extending fastening member 48 so that it cannot be seen from the outside. Thereby, the mounting work of the eaves ceiling mounting structure is completed.
[0028]
Next, the operation and effect of the above-described embodiment will be described.
In the present embodiment, the extending portion 30 extends downward from the building housing 40 side of the eaves ceiling main body 20 so as to be fixed to the building housing 40 below the eaves ceiling main body 20. For this reason, with only the end of the eaves ceiling body 20 on the eaves 70 side fixed to the back of the eaves, the end of the eaves ceiling body 20 on the building frame 40 side is moved vertically to The mounting position of the eaves ceiling main body 20 can be determined while checking the state. Then, after determining the mounting position of the eaves ceiling main body 20, the extended portion 30 can be fixed to the building frame 40. Thereby, the horizontal level adjustment of the eaves ceiling main body 20 can be facilitated, and the installation work in the field construction can be simplified.
[0029]
In addition, since the end of the eaves ceiling body 20 on the side of the building frame 40 is directly fixed to the building frame 40 by the extended portion 30, it is necessary to lay a base material for fixing the eaves ceiling body 20 to the building frame 40 Absent. As a result, the number of members used for attaching the eaves ceiling main body 20 can be reduced, and the work itself can be simplified.
In the present embodiment, the holding portion 32 is formed with a ventilation port 34 penetrating in the vertical direction. For this reason, even after the eaves ceiling 10 is formed, air can freely pass between the back of the eaves and the outside through the ventilation port 34 and the gap between the eaves ceiling main body 20 and the upper part of the outer wall decorative material 50. It can be moved, and the ventilation of the eaves can be improved.
