The roof frame, the vertical frame member is a common frame positioned inside the width side portions of the roof surface member,
The common frame is characterized in that a second vertical frame member according to a roof specification can be attached to an outer surface of the vertical frame member.
本発明によれば、上記構成によって、屋根パネルの生産性を向上することなどができる。 According to the present invention, with the above configuration, it is possible to improve the productivity of the roof panel.
以下、本実施の形態を、図面を用いて詳細に説明する。
図１〜図９は、この実施の形態を説明するためのものである。
Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 9 are for explaining this embodiment.
＜構成＞以下、構成について説明する。 <Structure> The structure will be described below.
図１に示すように、住宅などの建物１の屋根２を屋根パネル３，４によって構成する。 As shown in FIG. 1, a roof 2 of a building 1 such as a house is composed of roof panels 3 and 4.
ここで、建物１は、どのような構造のものであっても良いが、例えば、ユニット建物５などとすることができる。ユニット建物５は、予め工場で製造した建物ユニット６を建築現場へ搬送して、建築現場で組み立てることによって短期間のうちに建物１を構築し得るようにしたものである。建物ユニット６は、基本形状が直方体状とされており、鋼製のものや木製のものなどが存在している。 Here, the building 1 may have any structure, but may be, for example, a unit building 5. The unit building 5 is configured so that the building unit 6 manufactured in advance in a factory is transported to a building site and assembled at the building site so that the building 1 can be constructed in a short period of time. The building unit 6 has a rectangular parallelepiped basic shape, and is made of steel, wood, or the like.
屋根２は、各種のものが存在しているが、この実施例の場合には、複数の建物ユニット６で構成された建物本体７の上部中央に屋根構造体８を設置し、屋根構造体８の外周に沿って、複数枚の屋根パネル３，４を斜めに設置したものなどとされている。 There are various types of roofs 2. In the case of this embodiment, a roof structure 8 is installed in the center of the upper part of a building body 7 composed of a plurality of building units 6, and the roof structure 8 A plurality of roof panels 3 and 4 are installed obliquely along the outer periphery of the.
屋根パネル３，４には、平面視ほぼ三角形状をした三角パネル（屋根パネル３）や、平面視ほぼ矩形状をした矩形パネル（屋根パネル４）などがあり、三角パネル（屋根パネル３）は屋根２のコーナー部分などに設置され、矩形パネル（屋根パネル４）は、三角パネル（屋根パネル３）の間などに設置される。屋根パネル３，４は、クレーンによって吊り上げられて、屋根構造体８の上部に取付けられた水上固定金具１１と、建物本体７の上部に取付けられた軒元固定金具１２との間に斜めに傾斜させた状態で支持固定される。但し、屋根パネル３，４を用いて構成される屋根２の構造は、これに限るものではない。 The roof panels 3 and 4 include a triangular panel (roof panel 3) having a substantially triangular shape in a plan view and a rectangular panel (roof panel 4) having a substantially rectangular shape in a plan view. The triangular panel (roof panel 3) is The rectangular panel (roof panel 4) is installed in a corner portion of the roof 2 or the like, and is installed between triangular panels (roof panel 3) or the like. The roof panels 3 and 4 are hoisted by a crane, and are inclined obliquely between a water fixture 11 attached to the upper part of the roof structure 8 and an eaves fixture 12 attached to the upper part of the building body 7. It is supported and fixed in this state. However, the structure of the roof 2 configured by using the roof panels 3 and 4 is not limited to this.
このうち、矩形パネル（屋根パネル４）は、図２（図３）に示すように、一対の縦枠材１３と一対の横枠材１４とを組み合わせて成る矩形状の屋根枠１５と、屋根枠１５の上面に張設された矩形状の屋根面材１６（図３）とを有するものとされる。 Among them, the rectangular panel (roof panel 4) is, as shown in FIG. 2 (FIG. 3), a rectangular roof frame 15 formed by combining a pair of vertical frame members 13 and a pair of horizontal frame members 14, and a roof. It has a rectangular roof surface member 16 (FIG. 3) stretched on the upper surface of the frame 15.
屋根パネル４は、どのような大きさとしても良いが、この実施例では、幅の広いパネルなど（例えば、幅約２５００ｍｍなどの幅広パネルまたは大判パネル）とされている。このような幅広パネルとすることにより、屋根２に対する屋根パネル４の施工効率を向上することが期待できる。 The roof panel 4 may have any size, but in this embodiment, it is a wide panel (for example, a wide panel having a width of about 2500 mm or a large format panel). With such a wide panel, it can be expected that the construction efficiency of the roof panel 4 on the roof 2 is improved.
一対の縦枠材１３および一対の横枠材１４は、それぞれ平行に設置される。縦枠材１３および横枠材１４は、例えば、２×４材などで構成することができる。縦枠材１３および横枠材１４は、それぞれ断面が縦長の状態で設置される。屋根枠１５の内側には、必要に応じて、横枠材１４と平行な横桟１７を単数または複数本設けることができる。横桟１７は、横枠材１４と同様に断面が縦長の状態で設置される。また、屋根面材１６は、屋根下地材などとなるものである。 The pair of vertical frame members 13 and the pair of horizontal frame members 14 are installed in parallel. The vertical frame member 13 and the horizontal frame member 14 can be composed of, for example, 2×4 material. Each of the vertical frame member 13 and the horizontal frame member 14 is installed with its cross section being vertically long. Inside the roof frame 15, one or a plurality of horizontal rails 17 parallel to the horizontal frame member 14 can be provided, if necessary. Like the horizontal frame member 14, the horizontal rail 17 is installed in a state where the cross section is vertically long. In addition, the roof surface material 16 serves as a roof base material and the like.
そして、上記のような構成に対し、この実施例は、以下のような構成を備えることができる。 Further, in contrast to the above configuration, this embodiment can have the following configuration.
（１）屋根枠１５は、縦枠材１３が、屋根面材１６の幅両側部よりも内側に位置された共用枠２１とされる。
共用枠２１は、縦枠材１３の外側面に屋根仕様に応じた第二の縦枠材２２を取付けられるようになっている。
(1) The roof frame 15 is the common frame 21 in which the vertical frame member 13 is positioned inside the width side portions of the roof surface member 16.
The common frame 21 is configured such that a second vertical frame member 22 according to roof specifications can be attached to the outer surface of the vertical frame member 13.
ここで、縦枠材１３は、屋根２の水上側から水下側へ向けて延ばされる部材であり、共用枠２１にとって、内垂木（第一の縦枠材）となるものである。縦枠材１３の外側面は、第二の縦枠材２２に対する取付面とされる。 Here, the vertical frame member 13 is a member that extends from the water side of the roof 2 toward the water side, and serves as an inner rafter (first vertical frame member) for the common frame 21. The outer side surface of the vertical frame member 13 is a mounting surface for the second vertical frame member 22.
共用枠２１は、縦枠材１３の外側面に第二の縦枠材２２を取付けたときに、第二の縦枠材２２が屋根面材１６の幅両側部からハミ出さないように、縦枠材１３を第二の縦枠材２２の分だけ内側に設置したものとされる。即ち、縦枠材１３は、屋根面材１６の幅両側部の位置よりも第二の縦枠材２２の断面の幅寸法分、または、それよりも僅かに大きい分だけ、幅方向の内側に設置される。 When the second vertical frame member 22 is attached to the outer surface of the vertical frame member 13, the common frame 21 has a vertical length so that the second vertical frame member 22 does not protrude from the width side portions of the roof surface member 16. It is assumed that the frame member 13 is installed inside by the amount of the second vertical frame member 22. That is, the vertical frame member 13 is positioned inside the width direction by the width dimension of the cross section of the second vertical frame member 22 or the position slightly larger than the positions of the width side portions of the roof surface member 16. It is installed.
共用枠２１は、一対の横枠材１４を同じ長さにしても良いが、例えば、水上側の横枠材１４が短くなり、水下側の横枠材１４が長くなるように、長さを異ならせても良い。この場合、水上側の横枠材１４は、一対の縦枠材１３の間に介在されて、両端部が縦枠材１３の上端部の内側面にそれぞれ当接固定される長さとされる。また、水下側の横枠材１４は、屋根面材１６の幅寸法とほぼ同じ長さとされる。そして、水下側の横枠材１４の水上側の面の端部近傍に、縦枠材１３の下端部が当接固定されるようにする。 The common frame 21 may have a pair of horizontal frame members 14 having the same length, but for example, the horizontal frame member 14 on the water side becomes shorter and the horizontal frame member 14 on the water side becomes longer. May be different. In this case, the horizontal frame member 14 on the water side is interposed between the pair of vertical frame members 13 and has a length such that both ends thereof are in contact with and fixed to the inner surface of the upper end portion of the vertical frame member 13, respectively. Further, the horizontal frame member 14 on the underwater side has substantially the same length as the width dimension of the roof surface member 16. Then, the lower end portion of the vertical frame member 13 is abutted and fixed near the end portion of the surface on the water side of the horizontal frame member 14 on the water side.
第二の縦枠材２２は、水上側から水下側へ向けて延ばされる部材であり、共用枠２１にとって外垂木となるものである。第二の縦枠材２２には、屋根仕様に応じた材質のものを適宜使用することができる。例えば、図２は、標準仕様の屋根パネル４を示しており、この場合には、第二の縦枠材２２に２×４材などが用いられる。第二の縦枠材２２は、縦枠材１３とほぼ同じ長さを有しており、縦枠材１３に対して釘やビスなどの固定具２３で横から固定されることで、縦枠材１３に対して二重化される（部分二重枠構造）。釘やビスなどの固定具２３は、第二の縦枠材２２の長手方向に沿って複数本設置される。釘やビスなどの固定具２３は、例えば、直線状に取付けても良いが、千鳥状に取付けるのが好ましい。第二の縦枠材２２は、図２（ｂ）に示すように、縦枠材１３に対し上部の位置が１ｍｍ程度以下の誤差となるように揃えて設置固定される。 The second vertical frame member 22 is a member that extends from the upper side of the water toward the lower side of the water, and serves as an outer rafter for the common frame 21. As the second vertical frame member 22, a material according to the roof specifications can be appropriately used. For example, FIG. 2 shows a standard specification roof panel 4, and in this case, 2×4 material or the like is used for the second vertical frame member 22. The second vertical frame member 22 has substantially the same length as the vertical frame member 13, and is fixed laterally to the vertical frame member 13 with a fixing tool 23 such as a nail or a screw, so that the vertical frame member 13 is fixed. The material 13 is doubled (partial double frame structure). A plurality of fixtures 23 such as nails and screws are installed along the longitudinal direction of the second vertical frame member 22. The fixtures 23 such as nails and screws may be attached linearly, for example, but it is preferable to attach them in a staggered manner. As shown in FIG. 2B, the second vertical frame member 22 is installed and fixed so that the upper position of the second vertical frame member 22 has an error of about 1 mm or less.
共用枠２１の上側部や下側部には、上記した水上固定金具１１や軒元固定金具１２に取付ける際に用いられる取付ボルト２４などが、縦枠材１３と第二の縦枠材２２とを貫通するように設置されても良い。また、共用枠２１の上側の内側部における、上側の取付ボルト２４の位置には、水上ジョイント金具２５などを取付けても良い。 At the upper side and the lower side of the common frame 21, the mounting bolts 24 and the like used when mounting the above-mentioned water fixing fitting 11 and the eaves fixing fitting 12 are connected to the vertical frame member 13 and the second vertical frame member 22. You may install so that it may penetrate. In addition, a water joint fitting 25 or the like may be attached to the position of the upper mounting bolt 24 in the upper inner portion of the shared frame 21.
なお、比較例として図４に示す、既存の標準仕様の屋根パネル４０の場合には、屋根枠１５が屋根面材１６とほぼ同じ大きさに形成されており、この屋根枠１５は、縦枠材１３の外側に第二の縦枠材２２のない一重枠構造となっている。よって、既存の標準仕様の屋根パネル４０は、この実施例の屋根パネル４とは、基本構造が異なっている。 In the case of the existing standard roof panel 40 shown in FIG. 4 as a comparative example, the roof frame 15 is formed to have substantially the same size as the roof panel 16, and the roof frame 15 is a vertical frame. It has a single frame structure in which the second vertical frame member 22 is not provided outside the member 13. Therefore, the existing standard roof panel 40 has a different basic structure from the roof panel 4 of this embodiment.
（２）図５（図６）に示すように、第二の縦枠材２２は、鋼製外垂木３１としても良い。
鋼製外垂木３１は、縦枠材１３よりも高さ寸法が小さいものとされて、屋根面材１６との間に隙間３２（図６）を有して取付けられても良い。
(2) As shown in FIG. 5 (FIG. 6 ), the second vertical frame member 22 may be a steel outer rafter 31.
The steel outer rafter 31 may be smaller in height than the vertical frame member 13 and may be attached with a gap 32 (FIG. 6) between the steel outer rafter 31 and the roof surface member 16.
ここで、鋼製外垂木３１は、どのようなものとしても良いが、例えば、ウェブ部３１ａの上下端部に共用枠２１の幅方向の外方へ延びる一対のフランジ部３１ｂ，３１ｃを有するＣ字断面のものなどとしても良い。鋼製外垂木３１には、屋根仕様（例えば、多雪地仕様や、太陽光パネル仕様や、瓦仕様や、幅広パネル仕様など）に応じて必要な強度を有するものが使用される。鋼製外垂木３１は、縦枠材１３とほぼ同じ長さを有しており、縦枠材１３に対してボルト・ナットなどの固定具３３で横から固定されることで、二重化される（部分二重枠構造）。その他の構成については、標準仕様の第二の縦枠材２２とほぼ同様である。 Here, the steel outer rafter 31 may be of any type, for example, a pair of flange portions 31b and 31c extending outward in the width direction of the common frame 21 at the upper and lower ends of the web portion 31a. It may have a letter cross section or the like. As the steel outer rafter 31, one having a necessary strength according to a roof specification (for example, a snowy area specification, a solar panel specification, a roof tile specification, a wide panel specification, etc.) is used. The steel outer rafter 31 has almost the same length as the vertical frame member 13, and is doubled by being fixed to the vertical frame member 13 from the side with a fixture 33 such as a bolt or a nut ( Partial double frame structure). Other configurations are almost the same as those of the second vertical frame member 22 of the standard specification.
鋼製外垂木３１は、図５（ｂ）に示すように、縦枠材１３に対し下部の位置を揃えて設置することで、屋根面材１６との間に所要の隙間３２を形成する。この隙間３２は、図６に示すように、屋根面材１６の上に屋根仕上材３５などを施工する際に、屋根仕上材３５などを固定するための固定具３６の先端部が鋼製外垂木３１に当たらないようにするための間隔が確保される。 As shown in FIG. 5( b ), the steel outer rafter 31 is installed with its lower portion aligned with the vertical frame member 13 to form a required gap 32 with the roof surface member 16. As shown in FIG. 6, when the roof finishing material 35 or the like is installed on the roof surface material 16, the gap 32 has a tip end of a fixture 36 for fixing the roof finishing material 35 or the like made of steel. An interval is secured to prevent the rafters 31 from hitting.
そして、屋根面材１６の上に対する屋根仕上材３５などの施工は、まず、図７に示すように、屋根面材１６の上にルーフィング材などの防水シート３７を敷設する。次に、屋根面材１６の水上側の辺部に沿って水上受鋼板３８を取付け、屋根面材１６の水上側の辺部に沿って軒先受金具３９を取付ける。そして、屋根面材１６の幅方向の側部に必要に応じて捨水切４１を取付ける。捨水切４１の取付けの際には、図８に示すように、第二の縦枠材２２の外側面の位置を基準にして寸法管理を行うようにする（寸法管理用治具４２）。 Then, in constructing the roof finishing material 35 and the like on the roof surface material 16, first, as shown in FIG. 7, a waterproof sheet 37 such as a roofing material is laid on the roof surface material 16. Next, the water receiving steel plate 38 is attached along the water side edge of the roof panel 16, and the eaves receiving bracket 39 is attached along the water edge of the roof panel 16. And the drainage 41 is attached to the side part of the roof surface material 16 of the width direction as needed. At the time of attaching the drainage 41, as shown in FIG. 8, dimension management is performed based on the position of the outer surface of the second vertical frame member 22 (dimension management jig 42).
また、図７に示すように、屋根面材１６の上面に、捨水切４１と平行となるようにアンカークリップ４３を所要の間隔で取付ける。捨水切４１やアンカークリップ４３は、板金用ビスやネジなどの固定具４４などを用いて上から屋根面材１６に取付ける。そして、捨水切４１とアンカークリップ４３との間や、隣接するアンカークリップ４３の間に、屋根仕上材３５を取付ける。そして、ルーフィング材などの防水シート３７を、屋根面材１６の縁部に合わせてカットする。 Further, as shown in FIG. 7, anchor clips 43 are attached to the upper surface of the roof panel 16 at required intervals so as to be parallel to the drainage 41. The drainage 41 and the anchor clip 43 are attached to the roof surface material 16 from above by using a fixing tool 44 such as a sheet metal screw or a screw. Then, the roof finishing material 35 is attached between the drainage drain 41 and the anchor clip 43 or between the adjacent anchor clips 43. Then, the waterproof sheet 37 such as a roofing material is cut along the edge of the roof surface material 16.
更に、隣接する屋根仕上材３５の側縁部間を上から目地カバー４５で覆い、目地カバー４５の所要位置に雪止金具などを取付けるようにする。途中、必要に応じてアンカークリップ４３の先端部や、水上受鋼板３８と目地カバー４５との間などに、変性シリコーンなどの防水シール剤４７を施工する。 Further, the space between the side edges of the adjacent roof finishing materials 35 is covered with a joint cover 45 from above, and a snow stopper or the like is attached to a desired position of the joint cover 45. Along the way, if necessary, a waterproof sealant 47 such as modified silicone is applied to the tip of the anchor clip 43 or between the water receiving steel plate 38 and the joint cover 45.
なお、比較例として図９に示す、既存の多雪地仕様の屋根パネル４０の場合は、屋根枠１５には、横枠材１４として２×４材が使用され、縦枠材１３として２×８材や、２×８材と同じ大きさの単板積層材４８が部分三重枠構造などとなるように使用されている。この場合には、２×４材と２×８材などとが混在されることによって、屋根枠１５の下側に段差が生じるので、生産設備には段差部分を支持するための定盤などが必要になる。また、２×８材や単板積層材４８はコストが高く、また、単板積層材４８は固くて釘が打ち難いなどの問題がある。 In addition, in the case of the existing heavy snowy roof panel 40 shown in FIG. 9 as a comparative example, the roof frame 15 uses 2×4 as the horizontal frame member 14 and 2× as the vertical frame member 13. Eight materials or a single plate laminated material 48 having the same size as the 2×8 material is used so as to have a partial triple frame structure or the like. In this case, a mixture of 2×4 material and 2×8 material causes a step on the lower side of the roof frame 15, so that the production equipment has a surface plate or the like for supporting the stepped portion. You will need it. Further, there are problems that the cost of the 2×8 material and the single plate laminated material 48 is high, and that the single plate laminated material 48 is hard and it is difficult to nail it.
よって、既存の多雪地仕様の屋根パネル４０は、図４に示す既存の一般地仕様の屋根パネル４０とは、厚みや基本構造などが全く異なるものとなっている。そして、既存の多雪地仕様の屋根パネル４０には、生産性が悪いという問題があった。これに対し、この実施例の場合には、多雪地仕様と一般地仕様とで、屋根パネル４の基本構造は同じで、生産性の良いものとなる。 Therefore, the existing snow panel roof panel 40 is completely different in thickness and basic structure from the existing general roof panel 40 shown in FIG. In addition, the existing roof panel 40 having a lot of snow has a problem of low productivity. On the other hand, in the case of this embodiment, the basic structure of the roof panel 4 is the same between the heavy snow area specification and the general area specification, and the productivity is good.
＜作用＞この実施例の作用は、以下の通りである。 <Operation> The operation of this embodiment is as follows.
この実施例の建物１では、建物本体７の上に複数枚の屋根パネル３，４を斜めに設置することで、屋根２が形成される。 In the building 1 of this embodiment, a roof 2 is formed by obliquely installing a plurality of roof panels 3 and 4 on a building body 7.
屋根パネル４には、例えば、一対の縦枠材１３と一対の横枠材１４とを組み合わせて成る矩形状の屋根枠１５と、屋根枠１５の上面に張設された矩形状の屋根面材１６とを有するものを使用することができる。 The roof panel 4 includes, for example, a rectangular roof frame 15 formed by combining a pair of vertical frame members 13 and a pair of horizontal frame members 14, and a rectangular roof surface member stretched on the upper surface of the roof frame 15. It is possible to use the one having 16 and.
そして、屋根パネル４を、仕様ごとにそれぞれ異なる構造にした場合、複数種類の屋根パネル４が存在することになるため、生産性が悪くなる。 If the roof panels 4 have different structures according to specifications, a plurality of types of roof panels 4 will be present, resulting in poor productivity.
＜効果＞この実施例によれば、以下のような効果を得ることができる。 <Effect> According to this embodiment, the following effects can be obtained.
（効果 １）屋根パネル４は、屋根枠１５を、屋根面材１６の幅両側部よりも内側に縦枠材１３が位置された共用枠２１としても良い。そして、共用枠２１は、縦枠材１３の外側面に屋根仕様に応じた第二の縦枠材２２を取付けられるようにしても良い。これにより、例えば、共用枠２１に屋根面材１６を張設した基本部分を予め作成して用意しておき、使用するときに共用枠２１を構成する縦枠材１３の外側面に第二の縦枠材２２を取付けるだけで、屋根仕様に応じた屋根パネル４を迅速且つ効率的に製造することができる。 (Effect 1) In the roof panel 4, the roof frame 15 may be used as the common frame 21 in which the vertical frame members 13 are positioned inside the width side portions of the roof surface member 16. The common frame 21 may have a second vertical frame member 22 attached to the outer surface of the vertical frame member 13 according to the roof specifications. Thereby, for example, a basic portion in which the roof surface material 16 is stretched over the common frame 21 is created and prepared in advance, and when used, a second portion is formed on the outer surface of the vertical frame material 13 that constitutes the common frame 21. Only by mounting the vertical frame member 22, the roof panel 4 according to the roof specifications can be manufactured quickly and efficiently.
なお、屋根面材１６は、共用枠２１に第二の縦枠材２２を取付けた後で、共用枠２１に取付けることで製造するようにしても良い。 The roof surface material 16 may be manufactured by attaching the second vertical frame member 22 to the common frame 21 and then attaching it to the common frame 21.
そして、共用枠２１は、既存の屋根枠１５と比べて面積が小さくなっているため、材料コストを抑制することができる。また、共用枠２１は、既存の屋根枠１５と同じ材料と、同じ生産設備とを用いて、ほぼ同様の製造工程で生産できるため、特に製造に手間やコストがかからない。よって、屋根パネル４の基本部分の共用化を図ることや、屋根仕様に応じた最適な屋根パネル４を自在に作れるようにすることや、屋根パネル４の生産性を向上することや、屋根パネル４のコストの削減を図ることなどが可能になる。 Since the common frame 21 has a smaller area than the existing roof frame 15, the material cost can be suppressed. Further, since the common frame 21 can be manufactured in almost the same manufacturing process by using the same material and the same production equipment as those of the existing roof frame 15, it does not particularly require labor and cost for manufacturing. Therefore, it is possible to share the basic parts of the roof panel 4, to make it possible to freely create the optimum roof panel 4 according to the roof specifications, to improve the productivity of the roof panel 4, and to It is possible to reduce the cost of 4.
（効果 ２）第二の縦枠材２２は、鋼製外垂木３１としても良い。これにより、鋼製外垂木３１は上下方向の荷重に対して高い剛性を有するので、共用枠２１に鋼製外垂木３１を取付けることで、高い強度の屋根パネル４を得ることができる。このような高強度の屋根パネル４は、例えば、多雪地仕様や太陽光パネル仕様や瓦仕様や大判パネル仕様などの場合に利用することができる。そして、高強度の屋根パネル４を、標準仕様の屋根パネル４と同じ厚みに仕上げることができる。 (Effect 2) The second vertical frame member 22 may be a steel outer rafter 31. As a result, the steel outer rafter 31 has high rigidity with respect to the load in the vertical direction, and therefore, by mounting the steel outer rafter 31 on the common frame 21, the roof panel 4 having high strength can be obtained. Such a high-strength roof panel 4 can be used, for example, in the case of heavy snowfall specifications, solar panel specifications, roof tile specifications, large-format panel specifications, and the like. Then, the high-strength roof panel 4 can be finished to have the same thickness as the standard-spec roof panel 4.
また、鋼製外垂木３１は、縦枠材１３よりも高さ寸法が小さく形成されて、屋根面材１６との間に隙間３２を有して取付けられるようにしても良い。これにより、屋根面材１６の上に屋根仕上材３５などを施工する際に、屋根仕上材３５などを固定する固定具３６が鋼製外垂木３１に当たらないようにすることができる。 Further, the steel outer rafter 31 may be formed to have a height dimension smaller than that of the vertical frame member 13 so as to be attached with a gap 32 between the steel outer rafter 31 and the roof surface member 16. Accordingly, when the roof finishing material 35 and the like are installed on the roof surface material 16, the fixture 36 that fixes the roof finishing material 35 and the like can be prevented from hitting the steel rafters 31.
