Description

本発明は、屋根パネルの施工方法に関し、特に木質建材を用い施工を容易にした屋根パネルの施工方法に関する。 The present invention relates to a method for constructing a roof panel, and more particularly to a method for constructing a roof panel that is easily constructed using a wooden building material.

木造建築における屋根の施工方法として、従来工法では、棟木、母屋、軒桁の間に垂木を架け、その上に野地板を張ってさらに断熱材やシール部材をおいて防水処理をし、その上に瓦や屋根板などの屋根外装材を置くなどの方法が採られていた。しかし、このような方法は、部材数が多く、また、高所での作業が多くなるなどの点で、施工工期が長くなり、結果的に高価になりがちであった。
このような問題を解決するために、屋根パネルを予め工場で作成しておき、これを施工現場に輸送して建設現場での作業を短縮する方法が提案されている。例えば、屋根パネルに嵌合孔を設け、これに横架材に設けた太柄を嵌め合わせることで位置決めする方法（特許文献１参照。）、屋根構成体に複数の係合部を設け、各係合部を互いに連結した状態で各屋根構成体を保持手段で連結したもの（特許文献２参照。）、屋根パネルを２つの傾斜面を有する支持部材上で棟用固定部材と規制材の間に固定するようにし、取り付け作業を屋根裏から可能にした構造（特許文献３参照。）が報告されている。
しかしながら、これらの従来の方法では、屋根パネルを所定の角度で取り付けるために特定の傾斜断面をもつ棟木や支持部材などが必要であり、これらの作成や取り付け作業に特別の工夫を要するため、必ずしも充分に施工工期が短縮できるとはいえないという問題があった。
特開平１１−２１０１４３号公報特開平１０−１９６０３５号公報特開平６−４２０９４号公報 As a construction method for roofs in wooden buildings, in the conventional construction method, a rafter is built between purlins, purlins, eaves girder, a ground plate is stretched on top of it, and a heat insulating material and a sealing member are provided for waterproofing. A method such as placing roof exterior materials such as tiles and roofing boards on the roof was used. However, such a method tends to be expensive as a result of a long construction period in terms of a large number of members and an increase in work at high places.
In order to solve such a problem, a method has been proposed in which a roof panel is prepared in a factory in advance and is transported to a construction site to shorten the work on the construction site. For example, a method of positioning by providing a fitting hole in a roof panel and fitting a thick pattern provided in a horizontal member to the roof panel (see Patent Document 1), a plurality of engaging portions are provided in a roof structure, Each roof structure is connected by holding means in a state where the engaging portions are connected to each other (see Patent Document 2), and the roof panel is placed between the ridge fixing member and the regulating member on the support member having two inclined surfaces. A structure (see Patent Document 3) in which the mounting operation is made possible from the attic has been reported.
However, in these conventional methods, a purlin or a support member having a specific inclined section is required to attach the roof panel at a predetermined angle, and special creation is required for the creation and attachment work. There was a problem that the construction period could not be shortened sufficiently.

このA側の屋根パネル１０には、棟用金具（ＰＭ２）８と桁用金具（ＰＫ１、ＰＫ２）９とが取り付けられる。図６に、本発明で用いられる金具の斜視図を示す。また、図７は、A側の屋根パネル１０でのこれらの金具と後の工程で取り付けられる棟用金具（ＰＭ１）８の取り付け位置を天井側から見た図で示す。 On the roof panel 10 on the A side, a ridge fitting (PM2) 8 and a girder fitting (PK1, PK2) 9 are attached. FIG. 6 shows a perspective view of the metal fitting used in the present invention. Moreover, FIG. 7 shows the attachment position of these metal fittings in the roof panel 10 on the A side and the metal fitting for building (PM1) 8 to be attached in a later process as seen from the ceiling side.

これらの金具のうち、棟用金具８のＰＭ２は、屋根パネル１０の中間の２本のＩ型ビーム４に取り付けられ、棟部分でA側の屋根パネル１０とＢ側の屋根パネル１０との連結に用いられる。また、後ほど両端のＩ型ビーム４に取り付けられる棟用金具８のＰＭ１は、A側及びＢ側の屋根パネル１０同士の連結とA側の屋根パネル１０とＢ側の屋根パネル１０との連結に用いられる。
棟用金具８は中央で所定の角度に折り曲げられた２片からなり、一方をA側の屋根パネル１０に取り付けられるＡ片８ａとすると、他方はＢ側の屋根パネル１０に取り付けられるＢ片８ｂであり、Ａ片８ａとＢ片８ｂのなす角βは、下地面の水平面に対する傾斜角をαとすると Among these brackets, PM2 of the ridge bracket 8 is attached to the two I-shaped beams 4 in the middle of the roof panel 10, and the ridge portion connects the roof panel 10 on the A side and the roof panel 10 on the B side. Used for. Further, the PM 1 of the ridge fitting 8 that is attached to the I-beams 4 at both ends later is used to connect the A-side and B-side roof panels 10 to each other and to connect the A-side roof panel 10 to the B-side roof panel 10. Used.
The building metal fixture 8 is composed of two pieces bent at a predetermined angle at the center. When one is an A piece 8a attached to the A side roof panel 10, the other is a B piece 8b attached to the B side roof panel 10. And the angle β formed by the A piece 8a and the B piece 8b is α, where the inclination angle of the base surface with respect to the horizontal plane is α.

β＝１８０°−２α
である。 β = 180 ° -2α
It is.

一方、桁用金具９のＰＫ２は、屋根パネル１０の中間の２本のＩ型ビーム４に取り付けられ、桁用レール２３と係合して屋根パネル１０の滑り止めの役割を果たすと共に、最終的に一部が桁２１に固定されて下地面の水平面に対する傾斜角αを形成する機能を有している。
桁用金具９のＰＫ２の桁用レール２３と係合する係合片９ｃは、Ｉ型ビーム４に固定されるビーム片９ａの一部を折り曲げて形成されており、ビーム片９ａと係合片９ｃとのなす角は９０°である。また、最終的に桁２１に固定される桁片９ｂとビーム片９ａとのなす角度γは、 On the other hand, the PK 2 of the girder metal fitting 9 is attached to the two I-beams 4 in the middle of the roof panel 10 and engages with the girder rail 23 to play a role of preventing the roof panel 10 from slipping. Are fixed to the beam 21 and have a function of forming an inclination angle α with respect to the horizontal plane of the base surface.
The engagement piece 9c that engages with the PK2 beam rail 23 of the beam bracket 9 is formed by bending a part of the beam piece 9a fixed to the I-shaped beam 4, and the beam piece 9a and the engagement piece are formed. The angle formed by 9c is 90 °. Further, the angle γ formed between the beam piece 9b and the beam piece 9a finally fixed to the beam 21 is

γ＝９０°＋α
である。また、桁用金具９のＰＫ１は屋根パネル１０の両端の２本のＩ型ビーム４に取り付けられ、ビーム片９ａと桁片９ｂを有している。 γ = 90 ° + α

A側の屋根パネル１０を、その桁用金具９のＰＫ２が桁用レール２３にかみ合うように置いて１１枚並び終えると、１枚目のパネルＡ−1に２枚目のパネルＡ−２を合わせ、両方のパネルの軒先部分と棟側が相互に一致していることを確かめる。同様に２枚目のパネルに３枚目を、というように順次合わせて行き、１１枚目まで合わせ終わるとさらに最後の１２枚目を上げて連結し、棟側、軒先側及び中間部の幅寸法を計測しながら所定の寸法になるように、屋根パネルの両側に角材などを置いて締め付ける。 When 11 pieces of the roof panel 10 on the A side are placed so that the PK2 of the girder metal fitting 9 is engaged with the girder rail 23, the second panel A-2 is attached to the first panel A-1. In addition, make sure that the eaves part and the ridge side of both panels match each other. Similarly, the third panel is sequentially aligned with the second panel, and when the 11th sheet is completed, the last 12th sheet is raised and connected, and the width of the ridge side, eaves side and middle part While measuring the dimensions, place square materials on both sides of the roof panel and tighten them so that the specified dimensions are obtained.

寸法が合ったら、パネル野地合板１側から桟材７を使ってパネル１０同士を縫い合わせ、さらに棟側上部を仮固定する。この状態でパネル１２枚をゆっくり起こして行って、図８に点線で示すように、桁用金具９のＰＫ１とＰＫ２が桁２１についたら上げるのを止め、組み合わされた１２枚の屋根パネル１０の両サイド及び中央部の下に妻壁を挟み込み、突っ張り材をA側の屋根パネル１０の下に噛まして支持しておく。 When the dimensions match, the panels 10 are sewn together using the crosspiece 7 from the panel field plywood 1 side, and the ridge side upper part is temporarily fixed. In this state, twelve panels are raised slowly, and as shown by the dotted lines in FIG. 8, when the PK1 and PK2 of the girder metal fitting 9 are attached to the girder 21, the raising is stopped, and the twelve roof panels 10 combined are combined. The wife wall is sandwiched between both sides and the center, and the bracing material is bitten under the roof panel 10 on the A side and supported.

次に、B側の屋根パネル１０に桁用金具（ＰＫ１、ＰＫ２）９を取り付け、B側の１枚目のパネルＢ−１を上に上げて、桁用金具９のＰＫ２が桁用レール２３に噛み合い、さらに、A側の屋根パネル１０の端に合うように、パネルＡ−１の棟用金具８のＰＭ１の上に載せる。
さらに、B側の２枚目のパネルＢ−２を上げて１枚目のパネルＢ−１とに合わせる。以下、順にB側の屋根パネル１０を上げて先のパネルに合せて１２枚並べて行く。１２枚連結したら、幅寸法を計測しながらA側と同じ幅の寸法になるように、屋根パネルの両側に角材などを置いて締め付ける。その後、Ｂ側にも妻壁を取り付け、A側の屋根パネル１０の下に噛ましてある突っ張り材をゆっくり取り去り、A側屋根パネル１０とＢ側屋根パネル１０とが棟部分で合わさるようにして、棟の水平を確認する。 Next, the girder metal fittings (PK1, PK2) 9 are attached to the roof panel 10 on the B side, the first panel B-1 on the B side is raised upward, and the PK2 of the girder metal fitting 9 becomes the rail 23 for the girder. And is placed on PM1 of the ridge bracket 8 of the panel A-1 so as to fit the end of the roof panel 10 on the A side.
Further, the second panel B-2 on the B side is raised to match the first panel B-1. In the following, the roof panel 10 on the B side is raised in sequence, and twelve pieces are arranged according to the previous panel. After twelve pieces are connected, measure the width dimension, and place and tighten square bars etc. on both sides of the roof panel so that it will have the same width as the A side. After that, the wife wall is also attached to the B side, the bracing material biting under the A side roof panel 10 is slowly removed, and the A side roof panel 10 and the B side roof panel 10 are joined together at the ridge part. Check the level of the building.

全パネルが取り付けられ、確認が終わると、棟用金具８のＰＭ１を所定の位置に取付け、ＰＭ２と共にビス止めする。さらに、屋根パネル１０下の妻壁も固定する。その後、棟部分、けらば部分などを処理し、仮桁角材２２などを撤去して終了する。 When all the panels are installed and the confirmation is completed, PM1 of the metal fitting 8 for the building is attached at a predetermined position and screwed together with PM2. Furthermore, the wife wall under the roof panel 10 is also fixed. Thereafter, the ridge portion, the loose portion, and the like are processed, and the temporary girder square member 22 and the like are removed, and the process ends.
