Description

本発明は、C形鋼からなる母屋間に屋根材を落とし込んで施工できる建築物の屋根構造及び屋根の施工方法に関する。   The present invention relates to a roof structure of a building and a roof construction method that can be constructed by dropping a roof material between purlins made of C-shaped steel.

従来、金属屋根を施工するには、C形鋼などの母屋の上に野地板や断熱材を敷き込んで金属屋根を葺くのが一般的であった。例えば特許文献1には、建築物の構造材(C形鋼)上にフレーム3、取付具4、取付部材5などを取り付け、この取付部材5に網状の支持部材9を配することで、取付部材5と下地材1で矩形の受部を形成してこの受部内に天井板2を配設する構成が提案されている。或いは折板等のように野地板なしで母屋上に葺く工法もある。   Conventionally, in order to construct a metal roof, it has been common to spread a metal roof by laying a base plate or a heat insulating material on a main building such as C-shaped steel. For example, in Patent Document 1, the frame 3, the fixture 4, the attachment member 5, etc. are attached on the structural material (C-shaped steel) of the building, and the mesh-like support member 9 is arranged on the attachment member 5. There has been proposed a configuration in which a rectangular receiving portion is formed by the member 5 and the base material 1 and the ceiling plate 2 is disposed in the receiving portion. Or there is a construction method that goes up to the main roof without a field board like a folded board.

一方、本願出願人は、断面「ユ」型の構造材を用いることにより屋根厚みを低減する提案(例えば特許文献2など)を行っている。   On the other hand, the applicant of the present application has made a proposal (for example, Patent Document 2) to reduce the roof thickness by using a structural material having a “Y” cross section.

実公平7−51536号公報No. 7-51536 特開平11−336244号公報JP-A-11-336244

しかしながら、前記特許文献1に記載の構造では、母屋(C形鋼)上からの屋根厚みが厚くなるものであった。このように屋根厚みが厚いという問題は、例えば母屋上にタイトフレーム状の支持部材を配して屋根板を配する多くの構造にも共通する問題でもあり、地球環境を叫ばれている現在では高断熱や屋上緑化、太陽電池などの仕様も増え、さらに屋根の厚みが増すばかりである。
さらに、前記特許文献1の構造では、多種類の部材3〜5が必要であるため、部材管理の面で面倒となり、部材数が増加することで当然取付作業の手間もかかっていた。また、高さ方向の厚みの変化(天井板2の有無、天井板2の厚さ等)に併せて取付具4やフレーム3を変更しなければならず、天井板2の有無や天井板2の厚さがその上方に施工される屋根構造に影響するという問題もあった。
However, in the structure described in Patent Document 1, the thickness of the roof from the top of the purlin (C-shaped steel) is increased. The problem that the roof thickness is thick in this way is also a problem common to many structures in which a roof frame is arranged by arranging a tight frame-like support member on the main roof, for example, and now the global environment is being screamed. The specifications for high thermal insulation, rooftop greening, solar cells, etc. have increased, and the thickness of the roof has only increased.
Furthermore, in the structure of Patent Document 1, since many types of members 3 to 5 are necessary, it is troublesome in terms of member management, and naturally, it takes time and effort for mounting due to an increase in the number of members. Further, the fixture 4 and the frame 3 must be changed in accordance with changes in the thickness in the height direction (the presence or absence of the ceiling plate 2, the thickness of the ceiling plate 2, etc.), and the presence or absence of the ceiling plate 2 or the ceiling plate 2 There is also a problem that the thickness of the roof affects the roof structure constructed above.

また、前記特許文献2の構造では、使用される断面「ユ」型の構造材がH形鋼、C形鋼(コ形鋼)、I形鋼などの形鋼のように一般資材でないため、一般的には受け入れ難く、特に強度特性を重視する公共物件にも受け入れにくいという問題があった。   Further, in the structure of Patent Document 2, the structural material having a cross-section “Y” shape used is not a general material such as a shape steel such as H-shape steel, C-shape steel (co-shape steel), and I-shape steel. In general, it was difficult to accept, and in particular, it was difficult to accept even public properties that emphasize strength characteristics.

そこで、本発明は、前記従来の問題点を解消することができる屋根構造及びその施工方法を提供することを目的とする。   Then, an object of this invention is to provide the roof structure which can eliminate the said conventional problem, and its construction method.

本発明は、上記に鑑み提案されたもので、躯体に所定間隔にて二本のC形鋼を背中合わせに組み合わせて固定し、各C形鋼に屋根材を取り付けた屋根構造であって、それぞれ屋根材の端縁を各C形鋼の開口部内に位置させ、各端縁にカバー材を重合させて取り付けてなることを特徴とする建築物の屋根構造(以下、第二の態様という)に関するものである。   The present invention has been proposed in view of the above, and is a roof structure in which two C-shaped steels are combined and fixed back to back at predetermined intervals, and a roofing material is attached to each C-shaped steel, The roof structure of a building (hereinafter referred to as the second aspect) is characterized in that the edge of the roof material is positioned in the opening of each C-shaped steel, and the cover material is polymerized and attached to each edge. Is.

また、本発明は、前記屋根構造において、C形鋼の内部に取り付けられる固定部材により屋根材の端縁をC形鋼の開口部に挟着させたことを特徴とする建築物の屋根構造をも提案する。   According to the present invention, there is provided a roof structure of a building characterized in that, in the roof structure, an edge of the roof material is sandwiched between openings of the C-shaped steel by a fixing member attached to the inside of the C-shaped steel. I also propose.

さらに、本発明は、躯体に所定間隔にて二本のC形鋼を背中合わせに組み合わせて固定し、隣り合う組み合わせ形鋼の間に屋根材を配設する屋根構造の施工方法であって、それぞれ屋根材の端縁を各C形鋼の開口部内に位置させ、各端縁にカバー材を重合させて取り付けることを特徴とする建築物の屋根の施工方法をも提案する。   Furthermore, the present invention is a construction method of a roof structure in which two C-shaped steels are combined and fixed back-to-back at a predetermined interval on a frame, and a roofing material is disposed between adjacent combined steel shapes, The construction method of the roof of a building characterized by positioning the edge of a roof material in the opening part of each C-shaped steel, and superposing | attaching a cover material on each edge is also proposed.

本発明の建築物の屋根構造は、母屋として用いられているC形鋼に直接的に屋根材を取り付ける構造であって、母屋(C形鋼)自体を屋根材の支持部材として用いる構造と言い換えることもできるので、屋根構造の厚みを薄くすることができる。そして、従来の多数種の部材を母屋に取り付ける構造に比べて面倒な部材管理、面倒な取付作業を不要とし、溶接不良の心配もなく、安全且つ確実に、手間もかからず施工できる。
さらに、カバー材が必要となるが、例えば屋根材は左右対称とすることもできる。
The roof structure of the building of the present invention is a structure in which a roof material is directly attached to a C-shaped steel used as a main building, and is rephrased as a structure in which the main building (C-shaped steel) itself is used as a supporting member for the roof material. As a result, the thickness of the roof structure can be reduced. Compared to the structure in which a large number of conventional members are attached to the purlin, troublesome member management and troublesome attachment work are not required, and there is no concern about poor welding, and construction can be performed safely and reliably without any trouble.
Furthermore, although a cover material is required, for example, the roof material can be symmetrical.

また、一般資材として用いられているC形鋼を用いるので、一般的に受け入れ易く、特に強度特性を重要視する公共物件にも受け入れ易いものとなる。また、同時に野地板の敷き込みが不連続になることはなく、内部結露、遮音、熱収縮音発生などのクレームの心配が軽減される。   In addition, since the C-shaped steel used as a general material is used, it is generally easy to accept, and in particular, public properties that emphasize strength characteristics are also easily accepted. At the same time, the laying of the field board does not become discontinuous, and the concerns about complaints such as internal condensation, sound insulation, and heat contraction noise are reduced.

特に、C形鋼の内部に取り付けられる固定部材により屋根材の端縁をC形鋼の開口部に挟着させた場合、ビス止めする場合に比べて屋根材の端縁を容易に且つ強固に取り付けることができる。   In particular, when the edge of the roofing material is clamped to the opening of the C-shaped steel by a fixing member attached to the inside of the C-shaped steel, the edge of the roofing material can be easily and firmly made as compared with the case of screwing. Can be attached.

本発明の施工方法は、前記のように母屋として用いられているC形鋼に直接的に屋根材を取り付け、母屋(C形鋼)自体を屋根材の支持部材として用いるので、従来の多数種の部材を母屋に取り付ける構造に比べて面倒な部材管理、面倒な取付作業を不要とし、溶接不良の心配もなく、安全且つ確実に、手間もかからず施工できる。   Since the construction method of the present invention attaches the roof material directly to the C-shaped steel used as the main building as described above, and uses the main building (C-shaped steel) itself as a support member for the roof material, the conventional multiple types Compared to the structure of attaching the members to the purlin, troublesome member management and troublesome attachment work are unnecessary, and there is no worry of welding failure, and construction can be performed safely and reliably without any trouble.

本発明の建築物の屋根構造は、母屋(躯体)として所定間隔に固定されているC形鋼に直接的に屋根材を取り付ける構造である。このC形鋼は、一般資材として用いられ、社団法人日本鉄鋼連盟ではリップ溝形鋼とも称され、極めて強度特性が高いものである。   The roof structure of a building of the present invention is a structure in which a roof material is directly attached to a C-shaped steel that is fixed at a predetermined interval as a main building (frame). This C-shape steel is used as a general material, and is also called a lip groove shape steel by the Japan Iron and Steel Federation, and has extremely high strength characteristics.

本発明にて、屋根材を取り付けるC形鋼は、保持部材(吊子)として機能させるものであって、このC形鋼の形状的特徴である上顎状の下向き片、下顎状の上向き片、及び溝状の内部空間の何れか一つ或いは複数を取付場所として有効に利用する。
このC形鋼は、躯体上に所定間隔に固定され、断面形状がH形、I形、C形、コ形等、多様な需要分野ごとの目的に応じ、鋼材組成や定形寸法なども多種類に及ぶ形鋼などと共に母屋を構成している。また、鉄骨等に限定されるものではなく、RC、木造等の躯体、或いはその表面上に発泡断熱材(ポリスチレン等)を配した上に取り付けられるものであってもよい。
In the present invention, the C-shaped steel to which the roofing material is attached functions as a holding member (hanger), and is an upper jaw-shaped downward piece, a lower jaw-shaped upward piece, which is a geometric feature of the C-shaped steel, In addition, any one or more of the groove-like internal spaces are effectively used as the mounting location.
This C-shaped steel is fixed on the frame at a predetermined interval, and its cross-sectional shape is H-shaped, I-shaped, C-shaped, U-shaped, etc. The main building is made up of steel shapes and other parts. Moreover, it is not limited to a steel frame or the like, but may be attached to a RC or wooden frame, or a foam insulation (polystyrene or the like) on the surface thereof.

前記C形鋼に取り付ける屋根材は、屋根表面に用いられる外装材でもよいし、屋根内部に用いられる下葺き材でもよい。このような屋根材としては、表面化粧鋼板、ラミネート鋼板、メッキ鋼板、ステンレス鋼板、アルミ合金板、チタン合金板、銅板、真鍮板、鉛板等の公知の金属素材等が適宜に用いられ、また表面側に防水シートが全面的に貼設されたものでもよく、逆に裏面側に金属同士の接触を阻害するための裏貼りシートを貼設したものでもよい。そして、これらを必要に応じてロール成形、或いはプレス成型、或いは両者の組合せにより成形(成型)したものを用いればよく、その素材厚は特に限定するものではない。また、C形鋼との接触部分や屋根材同士の接触部分に発泡系ゴム等の適宜材料を添設して止水作用や接触阻害作用を得るようにしてもよい。   The roofing material attached to the C-shaped steel may be an exterior material used on the roof surface or an underlaying material used inside the roof. As such a roofing material, well-known metal materials such as surface decorative steel plates, laminated steel plates, plated steel plates, stainless steel plates, aluminum alloy plates, titanium alloy plates, copper plates, brass plates, lead plates, etc. are used as appropriate. The waterproof sheet may be entirely pasted on the front surface side, or conversely, the back sheet may be pasted on the back surface side to inhibit contact between metals. And what is necessary is just to use what was shape | molded by roll molding, press molding, or the combination of both as needed (the material thickness), and the raw material thickness is not specifically limited. Further, an appropriate material such as foam rubber may be added to the contact portion with the C-shaped steel or the contact portion between the roof materials to obtain a water stop action or a contact inhibition action.

屋根材は、図示参考例の態様では、一方の端縁をC形鋼の開口部内に位置させる取付端部とし、他方の端縁をC形鋼を覆うと共に一方の端縁に重合する重合端部とする。尚、「端縁」とは、先端のみを指すものではなく、先端付近(近傍)を指すものとする。したがって、「端縁を開口部内に位置させる」とは、先端は必ずしも開口部内に位置していなくてもよく、先端付近(近傍)の一部が開口部内に位置していればよい。   In the aspect of the illustrated reference example, the roofing material has one end edge as a mounting end portion positioned in the opening of the C-shaped steel, and the other end covers the C-shaped steel and overlaps with the one end edge. Part. It should be noted that the “edge” does not indicate only the tip, but indicates the vicinity (near) of the tip. Therefore, “the end edge is positioned in the opening” means that the tip does not necessarily have to be positioned in the opening, and only a part in the vicinity (near the tip) needs to be positioned in the opening.

そして、取付端部(一方の側縁)は、開口部内にビス止め、係止(嵌合を含む)、或いは挟着などにて取り付けられる。ビス止めの場合には、ビス孔からの水の浸入を防止するため、止水材を用いることが望ましいが、その外側を他方の端縁(重合端部)にて覆う(重合する)ので、必ずしも止水材は必要ではない。尚、挟着とは、C形鋼と固定部材(部分吊子)との間に係止することを指す。   The attachment end (one side edge) is attached to the opening by screwing, locking (including fitting), or pinching. In the case of screwing, it is desirable to use a water-stopping material in order to prevent water from entering from the screw hole, but the outside is covered (polymerized) with the other edge (polymerization end), so A waterstop material is not always necessary. In addition, clamping refers to latching between C-shaped steel and a fixing member (partial suspension).

それに対し、重合端部(他方の側縁)は、C形鋼の他方側から臨んで上フランジを覆い、さらに前記取付端部に重合する。この重合端部の取付手段については係合(嵌合を含む)にてC形鋼に取り付けられることが望ましい。   On the other hand, the overlapping end portion (the other side edge) faces the other side of the C-shaped steel, covers the upper flange, and further overlaps with the mounting end portion. The means for attaching the overlapping end is preferably attached to the C-shaped steel by engagement (including fitting).

本発明においては、二本のC形鋼の開口部がそれぞれ外方を向くように背中合わせに組み合わせて固定する。
また、屋根材は、両方の端縁が開口部内に位置させる取付端部となる。
そして、屋根材の各端縁(取付端部)にカバー材を重合させて取り付ける。
このカバー材は、組み合わせ形鋼の各上フランジを覆う傘状部と、その両端に設けられる脚状部とからなり、脚状部は、前記図示参考例の態様における屋根材の他方の端縁(重合端部)とほぼ同様の構成である。
In the present invention, the two C-shaped steel openings are combined and fixed back to back so that the openings are directed outward.
Further, the roof material is an attachment end portion in which both end edges are positioned in the opening.
And a cover material is superposed | polymerized and attached to each edge (attachment edge part) of a roof material.
This cover material is composed of an umbrella-shaped portion covering each upper flange of the combination steel and leg-shaped portions provided at both ends thereof, and the leg-shaped portion is the other edge of the roof material in the embodiment of the illustrated reference example. The configuration is substantially the same as (Polymerization end).

前記のように本発明においてC形鋼は、保持部材(吊子)として機能させるが、取付端部の取り付けに際して別部材の固定部材(補助保持部材)を用い、取付端部をC形鋼との間に挟着状に保持してもよい。
この固定部材としては、各種の構成があるが、以下の態様のものが好ましい。
As described above, in the present invention, the C-shaped steel functions as a holding member (hanger), but when attaching the mounting end, a separate fixing member (auxiliary holding member) is used, and the mounting end is defined as C-shaped steel. It may be held in a sandwiched manner.
The fixing member has various configurations, but the following modes are preferable.

・固定部材(部分吊子)ア
ビス等にて取り付けた施工後には、この固定部材と取付端部を挟着状に保持するものである。
例えば図示実施例(固定部材4)に示すようにC形鋼の開口部内に位置させた取付端部を押圧する脚片と、C形鋼に固定される固定部とを備え、固定部を固定した状態では脚片は取付端部の外側に沿い、取付端部をC形鋼の内面に挟着状に保持する。
・ After installation with fixing member (partial suspension) screws, etc., the fixing member and the mounting end are held in a sandwiched manner.
For example, as shown in the illustrated embodiment (fixing member 4), a leg piece that presses the mounting end positioned in the opening of the C-shaped steel and a fixing portion that is fixed to the C-shaped steel are provided, and the fixing portion is fixed. In this state, the leg pieces are along the outside of the attachment end portion, and the attachment end portion is held in a sandwiched manner on the inner surface of the C-shaped steel.

・固定部材(固定調整金具)イ
締め付け圧力を加減しつつ取付端部を押圧してC形鋼の内面に挟着状に圧着するものである。
例えば図示実施例(固定部材7)に示すようにC形鋼の開口部内に取付端部を位置させた状態で、調整ボルトを締め付けることにより、縦片状の本体の内端にて取付端部を下フランジの上向き片の内面に圧着すると共に本体の外端を上フランジの下向き片の内面に挟着状に保持して自らの定着性も確保できる。
・ Fixing member (fixing adjustment bracket) b. The mounting end is pressed while adjusting the tightening pressure, and is crimped to the inner surface of the C-shaped steel.
For example, as shown in the illustrated embodiment (fixing member 7), the mounting end is positioned at the inner end of the longitudinal piece of the main body by tightening the adjusting bolt with the mounting end positioned in the opening of the C-shaped steel. Can be pressure-bonded to the inner surface of the upper piece of the lower flange and the outer end of the main body can be clamped on the inner surface of the lower piece of the upper flange to secure its own fixing property.

図1(a)に示す参考例は、躯体1にピース材であるL型アングル材10を介して所定間隔でC形鋼2が固定され、C形鋼2の開口部側(図面左側)に配した屋根材3aの端縁(以下、取付端部という)32を開口部内に位置させ、背面側に配した屋根材3aの端縁(以下、重合端部という)33を開口部側の屋根材3aに重合させて取り付けられている。   In the reference example shown in FIG. 1 (a), a C-shaped steel 2 is fixed to a housing 1 at predetermined intervals via an L-shaped angle material 10 which is a piece material, and the C-shaped steel 2 has an opening (on the left side in the drawing). An edge (hereinafter referred to as an attachment end) 32 of the arranged roof material 3a is positioned in the opening, and an edge (hereinafter referred to as a superposed end) 33 of the roof 3a disposed on the back side is a roof on the opening side. The material 3a is attached by being polymerized.

図示参考例のC形鋼2は、前述のようにリップ溝形鋼とも言われるものであって、縦ウエブ21は鉛直状で、共に図面左方へ延びる上フランジ22及び下フランジ23は水平状である。また、上フランジ22の先端には上顎状の鉛直状下向き片221が設けられ、下フランジ23の先端には下顎状の鉛直状上向き片231が設けられている。そして、このC形鋼2は、極めて強度特性が高いものである。   The C-shaped steel 2 of the illustrated reference example is also called a lip groove-shaped steel as described above, and the vertical web 21 is vertical, and the upper flange 22 and the lower flange 23 both extending leftward in the drawing are horizontal. It is. Further, an upper jaw-shaped vertical downward piece 221 is provided at the distal end of the upper flange 22, and a lower jaw-shaped vertical upward piece 231 is provided at the distal end of the lower flange 23. And this C-shaped steel 2 has a very high strength characteristic.

図示参考例の屋根材3aは、図1(b)に示すように略平坦状の面板部31に左右非対称状の取付端部32,重合端部33を設けた構成であり、取付端部32は、面板部31の右端を傾斜状に折り上げると共に、外側へ略コ状に突出する隆起部分321を形成した構成であり、ぞの上下には基端側の下側折り上げ部分322、上端側の上側折り上げ部分323が形成されている。
C形鋼2を覆うと共に前記取付端部32に重合する重合端部33は、面板部31の左端を傾斜状に折り上げて途中に略く字状の折曲部分を形成し、その上端を略水平方向に折曲して水平部331とし、その先端を傾斜状に折り下げて前記折り上げ傾斜部分とほぼ同様に加工した。そして、略く字状の折曲部分を332、その下方の添設部を333とした。
As shown in FIG. 1B, the roof material 3 a of the illustrated reference example has a configuration in which a substantially flat face plate portion 31 is provided with left and right asymmetric mounting ends 32 and overlapping end portions 33. Is a structure in which the right end of the face plate portion 31 is folded up in an inclined shape and a raised portion 321 protruding substantially in a U shape outward is formed. An upper folded portion 323 on the side is formed.
The overlapping end portion 33 that covers the C-shaped steel 2 and overlaps with the attachment end portion 32 folds the left end of the face plate portion 31 into an inclined shape to form a substantially square-shaped bent portion in the middle, and the upper end thereof The horizontal portion 331 was bent in a substantially horizontal direction, and the tip thereof was folded in an inclined shape and processed in substantially the same manner as the above-mentioned inclined portion. The substantially bent portion is 332, and the lower portion is 333.

そして、図1(a)の屋根構造を施工するには、躯体1にL型アングル材10を介して固定したC形鋼2,2間に、屋根材3aを落とし込むように配し、まずC形鋼2の開口部側に配した屋根材3aの取付端部32を開口部内に位置させるように取り付ける。
より具体的には、取付端部32の隆起部分321を、C形鋼2の開口部から、即ち上向き片231と下向き片221との間から内部に配置させる(係止させる)と共に、上側折り上げ部分323を下向き片221の外側に沿わせる。尚、この上側折り上げ部分323と下向き片221については、図2(c)に示すようにビス止めするようにしてもよい。
And in order to construct the roof structure of Fig.1 (a), it arrange | positions so that the roofing material 3a may be dropped between the C-shaped steels 2 and 2 fixed to the housing 1 via the L-shaped angle material 10, and C It attaches so that the attachment end part 32 of the roofing material 3a distribute | arranged to the opening part side of the shape steel 2 may be located in an opening part.
More specifically, the raised portion 321 of the attachment end portion 32 is disposed (locked) from the opening of the C-shaped steel 2, that is, between the upward piece 231 and the downward piece 221 and is folded upward. The raised portion 323 is placed along the outside of the downward piece 221. The upper folded portion 323 and the downward piece 221 may be screwed as shown in FIG.

次に、C形鋼3の背面側に配した屋根材3aの重合端部33を、C形鋼2を覆うと共に取付端部32に重合するように取り付ける。
より具体的には、重合端部33の水平部331を、C形鋼3の上フランジ22の上面に被覆状に沿わせ、略く字状の折曲部分332及びその下方の添設部333が前記隆起部分321の外側(より詳細には隆起部分321の外側にで形成された凹状空間)に配置するように取り付けた。
Next, the overlapping end portion 33 of the roofing material 3 a disposed on the back side of the C-shaped steel 3 is attached so as to cover the C-shaped steel 2 and overlap with the mounting end portion 32.
More specifically, the horizontal portion 331 of the overlapping end portion 33 is covered with the upper surface of the upper flange 22 of the C-shaped steel 3 so as to cover the substantially rectangular shape and the additional portion 333 below the bent portion 332. Is attached so as to be arranged outside the raised portion 321 (more specifically, a concave space formed outside the raised portion 321).

このように施工される屋根構造は、母屋として用いられているC形鋼2に直接的に屋根材3aを取り付ける構造であって、母屋(C形鋼2)自体を屋根材3aの支持部材として用いる構造と言い換えることもでき、屋根構造の全体厚みを薄くすることができる。   The roof structure thus constructed is a structure in which the roof material 3a is directly attached to the C-shaped steel 2 used as the main building, and the main building (C-shaped steel 2) itself is used as a support member for the roof material 3a. It can be paraphrased as the structure to be used, and the overall thickness of the roof structure can be reduced.

また、図示参考例の施工状態では、重合端部33の添設部333と取付端部32の下側折り下げ部分323とは恰も上下に連続するような面を形成した。   Moreover, in the construction state of the illustrated reference example, the attachment portion 333 of the overlapping end portion 33 and the lower folded portion 323 of the attachment end portion 32 formed a surface in which the wrinkles were also continued vertically.

図2(a)に示す参考例は、前記図1の参考例に、図2(b)に示す固定部材(部分吊子)4を取り付けた構成である。
この固定部材4は、材質は主にアルミ、ステンレス、硬質樹脂であり、押出成型、プレス成型、ロール成型などにて成型されるものであって、前記アの態様、即ちC形鋼2の開口部内に位置させた屋根材3aの取付端部32を上方から押さえる脚片41と、C形鋼2の上フランジ22に固定される固定部42(ビス43)とを備える部分吊子であって、配設状態では、脚片41は隆起部分321と折曲部分332,添設部333との間に配設される。そのため、屋根材3aの取付端部32は、開口部内に係止されると共に、固定部材4の脚片41とC形鋼2との間に挟着状に保持され、より安定に取り付けられる。
図2(c)に示す参考例は、前記図1の参考例における屋根材3aの取付端部32の上側折り上げ部分323を、C形鋼2の下向き片221の外側に沿わせた状態で、ビス324によってビス止めしている。この参考例でも、取付端部32はより安定に取り付けられるものとなる。
The reference example shown in FIG. 2A has a configuration in which the fixing member (partial suspension) 4 shown in FIG. 2B is attached to the reference example shown in FIG.
The fixing member 4 is mainly made of aluminum, stainless steel, or hard resin, and is formed by extrusion molding, press molding, roll molding, or the like. It is a partial suspension provided with a leg piece 41 that holds down the attachment end 32 of the roofing material 3a positioned in the part from above and a fixing part 42 (screw 43) fixed to the upper flange 22 of the C-shaped steel 2. In the disposition state, the leg piece 41 is disposed between the raised portion 321, the bent portion 332, and the attachment portion 333. Therefore, the attachment end portion 32 of the roof material 3a is locked in the opening, and is held in a sandwiched manner between the leg piece 41 of the fixing member 4 and the C-shaped steel 2 and is attached more stably.
In the reference example shown in FIG. 2C, the upper folded portion 323 of the attachment end portion 32 of the roof material 3 a in the reference example of FIG. 1 is placed along the outside of the downward piece 221 of the C-shaped steel 2. The screw is fixed with a screw 324. Also in this reference example, the attachment end portion 32 is attached more stably.

この図2(a)の屋根構造は、部分吊子である固定部材4が屋根材3aの取付端部32を挟着状に保持するので、前記図1の屋根構造のように屋根材3aの取付端部32を係止(嵌合)のみで取り付ける場合に比べて、より安定な取付強度が得られる。図2(c)の屋根構造も、屋根材3aの取付端部32をビス止めしたので、係止(嵌合)とビス止めにて取り付けられるものとなり、安定な取付強度が得られる。   In the roof structure of FIG. 2 (a), the fixing member 4 which is a partial suspension holds the attachment end 32 of the roof material 3a in a sandwiched manner. Therefore, like the roof structure of FIG. More stable attachment strength can be obtained as compared with the case where the attachment end portion 32 is attached only by locking (fitting). In the roof structure of FIG. 2C as well, the attachment end portion 32 of the roof material 3a is screwed, so that it can be attached by locking (fitting) and screwing, and stable attachment strength is obtained.

図3(c)に示す実施例は、躯体1に所定間隔にて二本のC形鋼2,2を背中合わせに組み合わせて固定し、各C形鋼2,2に屋根材6,6を取り付けた屋根構造であって、それぞれ屋根材6,6の取付端部62を各C形鋼2の開口部内に位置させ、各取付端部62にカバー材5を重合させて取り付けている。
この屋根構造における屋根材6は、両方の端縁が開口部内に位置させる取付端部62である以外は、前記屋根材3aと同様と同じ構成であって、固定部材4を用いて取り付ける構成は、前記図2(a)と同様である。さらに、カバー材5は、前記屋根材3a,6と略同様の素材からなり、中央が頂部となる傘状部51と、その両端に設けられる脚状部52,52とからなり、脚状部52の形状は、前記図2(a)の参考例における屋根材3aの重合端部33の折曲部分332,添設部333とほぼ同様である。
In the embodiment shown in FIG. 3 (c), two C-shaped steels 2, 2 are combined and fixed back to back at a predetermined interval, and roofing materials 6, 6 are attached to each C-shaped steel 2, 2. In the roof structure, the attachment end portions 62 of the roof materials 6 and 6 are respectively positioned in the openings of the C-shaped steels 2 and the cover materials 5 are superposed and attached to the attachment end portions 62.
The roofing material 6 in this roof structure has the same configuration as the roofing material 3a except that both end edges are located in the opening, and the configuration for mounting using the fixing member 4 is as follows. This is the same as FIG. 2 (a). Further, the cover material 5 is made of a material substantially the same as the roof materials 3a, 6 and is composed of an umbrella-shaped portion 51 whose top is the top and leg-shaped portions 52, 52 provided at both ends thereof. The shape of 52 is substantially the same as the bent portion 332 and the attachment portion 333 of the overlapping end portion 33 of the roof material 3a in the reference example of FIG.

そして、図3(c)の屋根構造を施工するには、図3(a)に示すように躯体1にL型アングル材10を介してC形鋼2,2を背中合わせに組み合わせて固定し、隣り合う組み合わせ形鋼II,II間に、屋根材6を落とし込むように配し、屋根材6の取付端部62を開口部内に位置させるように取り付ける。より具体的には、取付端部62の隆起部分621を、C形鋼2の開口部から内部に配置させる(係止させる)と共に、上側折り上げ部分623を下向き片221の外側に沿わせる。   And in order to construct the roof structure of FIG.3 (c), as shown to Fig.3 (a), the C-shaped steel 2 and 2 are combined and fixed to the housing 1 through the L-shaped angle material 10 back to back, The roof material 6 is arranged so as to drop between the adjacent combination steels II and II, and the attachment end 62 of the roof material 6 is attached so as to be positioned in the opening. More specifically, the raised portion 621 of the attachment end 62 is disposed (locked) from the opening of the C-shaped steel 2 and the upper folded portion 623 is made to extend along the outside of the downward piece 221.

次に、固定部材4を取り付けるが、前記図2(a)の参考例と同様に脚片41を、C形鋼2の開口部内に位置させた屋根材6の取付端部62を上方から押さえるように臨ませた状態で、固定部42を、C形鋼2の上フランジ22にビス43にて固定する。
その後、図3(b)に示すように、カバー材5を固定部材4の固定部42の上方から被せ、脚状部52が前記隆起部分621の外側(より詳細には隆起部分621の外側にで形成された凹状空間)に配置するように取り付けた。
Next, the fixing member 4 is attached. As in the reference example of FIG. 2A, the leg piece 41 is pressed from above on the attachment end portion 62 of the roofing material 6 positioned in the opening of the C-shaped steel 2. In this state, the fixing portion 42 is fixed to the upper flange 22 of the C-shaped steel 2 with screws 43.
Thereafter, as shown in FIG. 3B, the cover material 5 is covered from above the fixing portion 42 of the fixing member 4, and the leg-shaped portion 52 is outside the protruding portion 621 (more specifically, outside the protruding portion 621. It was attached so as to be disposed in a concave space formed in (1).

こうして得られる図3(c)の屋根構造では、組み合わせ形鋼IIを用いたので開口部が左右両側に形成されるが、それらを固定部材4,4が覆うので、強度の弱点部とならず、高強度の屋根構造が得られ、さらに左右対称の屋根材6を適用することができる。   In the roof structure of FIG. 3 (c) obtained in this way, since the combination shape steel II is used, the openings are formed on both the left and right sides, but since they are covered by the fixing members 4 and 4, they are not weak points. A high-strength roof structure can be obtained, and a symmetrical roof material 6 can be applied.

図4(f)に示す参考例は、図4(a)〜(d)に示す固定部材(固定調整金具)7を用いて屋根材3bの取付端部32を保持するようにした例である。
この固定部材7は、アルミ等の押出材などにて略L字状に成形された本体と、調整ボルト70とからなる固定調整金具であり、前記イの態様、即ちC形鋼の開口部内に位置させた状態で押圧(係止)できる機構を備え、その機構により屋根材3bの端縁を押さえ付けると共に自らの定着性も確保することができる。
The reference example shown in FIG. 4 (f) is an example in which the attachment end 32 of the roofing material 3b is held using the fixing member (fixed adjustment fitting) 7 shown in FIGS. 4 (a) to 4 (d). .
The fixing member 7 is a fixing adjustment fitting including a main body formed in an approximately L shape with an extruded material such as aluminum and an adjustment bolt 70, and the above-mentioned aspect, that is, in the opening of the C-shaped steel. A mechanism that can be pressed (locked) in a positioned state is provided, and by this mechanism, the edge of the roofing material 3b can be pressed down and its own fixing property can be secured.

この固定部材7の略L字状本体は、矩形状の縦面部71と略水平状の底面部72とでL型を形成しており、縦面部71の上端には底面部72と逆方向に突出する横面部73とからなる。
図4(b),(c)に示すように縦面部71の高さ寸法は、C形鋼2の開口部Bより大きくその高さAより小さいものであり、縦面部71の幅寸法Yは、C形鋼2の開口部Bより小さく、斜め寸法Xは、C形鋼2の高さAより小さく形成されている。そして、この縦面部71には、調整ボルト70が軸着されている(701はナット溶接)。
The substantially L-shaped main body of the fixing member 7 forms an L shape with a rectangular vertical surface portion 71 and a substantially horizontal bottom surface portion 72, and an upper end of the vertical surface portion 71 is opposite to the bottom surface portion 72. It consists of a projecting lateral surface 73.
As shown in FIGS. 4B and 4C, the height dimension of the vertical surface portion 71 is larger than the opening B of the C-shaped steel 2 and smaller than the height A, and the width dimension Y of the vertical surface portion 71 is The diagonal dimension X is smaller than the opening B of the C-shaped steel 2 and smaller than the height A of the C-shaped steel 2. An adjustment bolt 70 is pivotally attached to the vertical surface portion 71 (701 is nut welding).

この固定部材7の取付手順は、以下の通りである。尚、固定部材7の取り付けに先立って屋根材3bの取付端部34をC形鋼2に取り付けておく。
まず、C形鋼2の開口部に対し、図4(d)に示すように幅寸法Yが高さになるように本体を回動した状態で矢印方向にスライドさせてC形鋼2の内部に固定部材7を位置させる。
次に、この状態で固定部材7を回動して図4(a)のようにL字形側面を見せるように配する。この時、底面部72は、屋根材3bの取付端部34(谷状部342)上に載置されている。
この状態で、開口部の外側から調整ボルト70を締め付けると、調整ボルト70の内端がC形鋼2の縦ウエブ21の内面に当接し、その後はナット溶接701の作用により本体を開口部側へ押し返すように作用する。そのため、縦面部71の下端であって底面部72の基端部分は取付端部34(山状部341)に側方から強く押し付けられ、取付端部34を安定に保持することができる。さらに、横面部73の先端はC形鋼2の下向き片221の内面に強く押し付けられるので、例えば傾動することもなく、固定部材7自体が安定に取り付けられるものとなる。
The attachment procedure of the fixing member 7 is as follows. Prior to attaching the fixing member 7, the attachment end 34 of the roof material 3 b is attached to the C-shaped steel 2.
First, with respect to the opening of the C-shaped steel 2, as shown in FIG. 4 (d), the body is rotated so that the width dimension Y becomes a height, and is slid in the direction of the arrow to The fixing member 7 is positioned on the surface.

In this state, when the adjusting bolt 70 is tightened from the outside of the opening, the inner end of the adjusting bolt 70 comes into contact with the inner surface of the vertical web 21 of the C-shaped steel 2, and thereafter the body is moved to the opening side by the action of the nut welding 701. Acts to push back. Therefore, the base end portion of the bottom surface portion 72 that is the lower end of the vertical surface portion 71 is strongly pressed from the side to the attachment end portion 34 (mountain portion 341), and the attachment end portion 34 can be stably held. Furthermore, since the front end of the lateral surface portion 73 is strongly pressed against the inner surface of the downward piece 221 of the C-shaped steel 2, for example, the fixing member 7 itself can be stably attached without tilting.

また、この図4の参考例における屋根材3bは、略平坦状の面板部31に左右非対称状の端縁(取付端部、重合端部)を設けた点では共通しているが、その端縁形状が異なる。
この参考例における取付端部34は、図4(e)に示すように面板部31の右端を傾斜状に折り上げてその上端を折り返して形成した山状部341と、その外側に略水平状に延在させてその外縁を折り上げた谷状部342とからなる。また、この参考例における重合端部35は、前記重合端部33とほぼ同様であり、C形鋼2の上フランジ22に沿う部分を水平部351、略く字状の折曲部分を352、その下方の添設部を353とした。

As shown in FIG. 4 (e), the attachment end 34 in this reference example has a mountain-shaped portion 341 formed by folding the right end of the face plate portion 31 in an inclined shape and folding the upper end thereof, and a substantially horizontal shape on the outside thereof. And a valley-shaped portion 342 which is extended to the outer edge and folded up. Further, the overlapping end portion 35 in this reference example is substantially the same as the overlapping end portion 33, a portion along the upper flange 22 of the C-shaped steel 2 is a horizontal portion 351, and a substantially rectangular bent portion is 352, The attachment portion below the reference portion was designated as 353.

そして、図4(f)の屋根構造を施工するには、躯体1にL型アングル材10を介して固定したC形鋼2,2間に、屋根材3bを落とし込むように配し、まずC形鋼2の開口部側に配した屋根材3bの取付端部34を開口部内に位置させるように取り付ける。
