Description

本発明は、採光部を備えた折板屋根において、火災等の際の飛び火に対する防火安全性を高めた構造を提供する屋根構造に関するものである。   The present invention relates to a roof structure that provides a structure with improved fire safety against a flying fire in the event of a fire or the like in a folded-plate roof provided with a daylighting unit.

工場や倉庫等の屋根に用いられる折板屋根に採光部を設ける場合、鋼板からなる金属折板屋根材の一部を透明な合成樹脂板からなる樹脂折板屋根材に置き替えることが考えられる。しかしながら、樹脂折板屋根材は、火災等の際に飛び火が飛来すると樹脂が溶融して孔があき、この孔から飛び火が屋内に入り込んだり、溶融した樹脂が屋内に落下するために、防火安全性に問題がある。   When installing a daylighting part on a folded-plate roof used for the roof of a factory or a warehouse, it is possible to replace a part of the metal folded-plate roof material made of a steel plate with a resin folded-plate roof material made of a transparent synthetic resin plate. . However, the resin folded plate roofing material is a fireproof safety because the resin melts and perforates when a spark comes in the event of a fire, etc., and the spark enters the interior from this hole or the molten resin falls indoors. There is a problem with sex.

そこで、従来は、金属折板屋根材の一部をガラス板に置き替えた発明がなされていた(例えば、特許文献1参照。)。ところが、ガラス板を金属折板屋根材の間に嵌め込む場合には、このガラス板を水密構造で取り付ける必要があるため、構造が複雑となり施工が面倒になるという問題があった。しかも、ガラス板は、変形による応力に耐えられず破損しやすいため、応力を受け止めガラスに伝えないような強固で精度の高い枠材を設けることが必要がとなり、これによっても構造が複雑となり高価になるという問題があった。さらに、ガラス板は、不燃性は高いが耐衝撃性が低いために、強風等で屋根に物が飛来すると破損しやすく、一旦破損した場合には修理作業が面倒になるという問題もあった。   Therefore, conventionally, an invention has been made in which a part of the metal folded plate roofing material is replaced with a glass plate (for example, see Patent Document 1). However, when the glass plate is fitted between the folded metal roof materials, it is necessary to attach the glass plate with a watertight structure, so that there is a problem that the structure becomes complicated and the construction becomes troublesome. Moreover, since glass plates cannot withstand the stress caused by deformation and are easily damaged, it is necessary to provide a strong and high-accuracy frame material that receives stress and does not transmit it to the glass, which also makes the structure complicated and expensive. There was a problem of becoming. Furthermore, since the glass plate has high incombustibility but low impact resistance, it easily breaks when an object comes to the roof due to strong winds or the like, and once broken, the repair work becomes troublesome.

また、従来は、金属折板屋根材の一部を、透光性の合成樹脂板の裏面に透光性と不燃性を有する透光不燃板を積層一体化した強化透光折板屋根材に置き替えた発明もなされていた(例えば、特許文献2参照。)。この強化透光折板屋根材は、合成樹脂板がガラス板等の透光不燃板に比べてある程度の耐衝撃性があり、この合成樹脂板に飛び火によって孔があいても、裏面の透光不燃板が飛び火や溶融樹脂を遮蔽することができるので、防火安全性が高い。ところが、この強化透光折板屋根材は、合成樹脂板の裏面に透光不燃板を積層一体化した複雑な構造であるため、単なる鋼板や合成樹脂板だけからなる折板屋根材に比べて製造コストが極めて高価になるという問題があった。

Moreover, conventionally, a part of the metal folded plate roofing material is changed to a reinforced translucent folded plate roofing material in which a translucent and incombustible translucent incombustible plate is laminated and integrated on the back surface of the translucent synthetic resin plate. A replacement invention has also been made (see, for example, Patent Document 2). This reinforced translucent folded plate roofing material has a certain level of impact resistance compared to a translucent incombustible plate such as a glass plate. Fireproof safety is high because the non-combustible plate can shield fire and molten resin. However, this reinforced translucent folded plate roofing material has a complex structure in which a translucent incombustible plate is laminated and integrated on the back surface of a synthetic resin plate, so compared to a folded plate roofing material consisting of only a steel plate or a synthetic resin plate. There has been a problem that the manufacturing cost becomes extremely high.

母屋材1は、屋根に配置される構造材であり、図2に示すように、左右に長尺なI形綱又はH形綱からなり、前後方向に2本以上(図2では2本だけを示す)が並んで平行に配置されている。また、これらの母屋材1は、図では示していないが、本実施形態の場合には、前方が水下となるように、前方のものほど高さが低く配置されている。なお、この母屋材1は、本実施形態のようなI形綱やH形綱には限定されず、任意の型綱やその他の材料の構造材が用いられていてもよい。
[Mounting structure of metal folded plate roofing material and resin folded plate roofing material]
The main building 1 is a structural material arranged on the roof, and as shown in FIG. 2, is composed of a long I-shaped rope or a H-shaped rope on the left and right, and two or more in the front-rear direction (only two in FIG. 2) Are arranged in parallel. Further, although not shown in the figure, these purlins 1 are arranged such that the height of the front one is lower so that the front is under water. The purlin material 1 is not limited to the I-shaped rope and the H-shaped rope as in the present embodiment, and any type of rope or other structural material may be used.

タイトフレーム2は、左右に細長い鋼板に上下方向の凸部である山部2aと凹部である谷部を左右方向に交互に形成したものであり、谷部を母屋材1の上面に溶接する等の方法により固着している。また、このタイトフレーム2の山部2aの頂部には、最も高い頂上よりも少し下がった平坦部が形成されると共にねじ孔が穿設されている。さらに、本実施形態のタイトフレーム2は、図示のような単なる細長い平板状ではなく、実際には、補強のために、長手方向に沿って横断面が半円形となるリブが形成されている。   The tight frame 2 is formed by alternately forming a crest 2a that is a convex portion in the vertical direction and a trough portion that is a concave portion in the left-right direction on a steel plate that is elongated to the left and right, and welding the trough to the upper surface of the base material 1. It is fixed by the method of. In addition, a flat portion slightly lower than the highest top is formed at the top of the peak portion 2a of the tight frame 2, and a screw hole is formed. Further, the tight frame 2 of the present embodiment is not a simple elongated flat plate as shown in the figure, but actually, a rib having a semicircular cross section along the longitudinal direction is formed for reinforcement.

なお、このタイトフレーム2の山部2aや谷部の形状は、金属折板屋根材3や樹脂折板屋根材4の折れ曲がり形状に合わせて任意であり、山部2aの頂部の構成、即ち平坦部やねじ孔の有無も任意である。また、このタイトフレーム2は、図1〜図9では山部2aが2箇所だけのものを示しているが、さらに多数の山部2aと谷部が形成されていてもよく、逆に山部2aが1箇所だけであってもよい。ただし、山部2aが少ないタイトフレーム2を用いる場合には、各母屋材1ごとに複数のタイトフレーム2を左右方向に連続して並べて固着する。さらに、このタイトフレーム2は、必要な強度が得られるならば、鋼板に限らず、その他の鋼材やステンレス綱等の他の金属材からなるものであってもよく、リブの有無も任意である。   In addition, the shape of the peak part 2a and the trough part of this tight frame 2 is arbitrary according to the bending shape of the metal folded-plate roof material 3 or the resin folded-plate roof material 4, and the structure of the top part of the peak part 2a, ie, flat The presence or absence of a part and a screw hole is also arbitrary. 1 to 9, the tight frame 2 has only two peak portions 2a. However, a large number of peak portions 2a and valley portions may be formed. 2a may be only one place. However, when using the tight frame 2 with few ridges 2a, a plurality of tight frames 2 are arranged in a row in the left-right direction for each purlin member 1 and fixed. Further, the tight frame 2 is not limited to a steel plate as long as a required strength is obtained, and may be made of other metal materials such as other steel materials and stainless steel, and the presence or absence of ribs is also arbitrary. .

金属折板屋根材3は、鋼板からなり、図1に示すように、上下左右方向に沿った断面の形状が、タイトフレーム2の山部2aの頂部から谷部を経て隣の山部2aの頂部に至る形状とほぼ同じ凹凸形状に形成されている。ただし、図1では、右側の金属折板屋根材3は、タイトフレーム2の山部2aの頂部からその右側の谷部までの一部だけを示し、左側の金属折板屋根材3は、タイトフレーム2の谷部からその右側の山部2aの頂部に至る一部だけを示している。なお、この金属折板屋根材3は、本実施形態のような鋼板に限らず、アルミニウムやステンレス綱等の他の金属板からなるものであってもよい。   The metal folded plate roofing material 3 is made of a steel plate, and as shown in FIG. 1, the shape of the cross section along the vertical and horizontal directions is from the top of the peak 2 a of the tight frame 2 to the valley of the adjacent peak 2 a. It is formed in substantially the same uneven shape as the shape reaching the top. However, in FIG. 1, the right metal folded plate roofing material 3 shows only a part from the top of the peak portion 2 a of the tight frame 2 to the right trough portion thereof, and the left metal folded plate roofing material 3 is tight. Only a part from the valley of the frame 2 to the top of the peak 2a on the right side is shown. In addition, this metal folded-plate roof material 3 may consist of other metal plates, such as not only a steel plate like this embodiment but aluminum, a stainless steel rope.

樹脂折板屋根材4は、透光性を有する合成樹脂板からなり、上下左右方向に沿った断面の形状が、タイトフレーム2の山部2aの頂部から谷部を経て隣の山部2aの頂部に至る形状とほぼ同じ凹凸形状に形成されている。ここで、透光性とは、可視光を透過する性質をいい、透明に限らず、例えば光を散乱させながら透過するものであってもよく、光の一部を吸収するものであってもよい。また、合成樹脂板としては、光透過率の高いポリカーボネート樹脂やアクリル樹脂の板材が最適であり、ポリエステル樹脂や塩化ビニル樹脂等の他の熱可塑性樹脂も好適に用いられるが、必ずしも熱可塑性樹脂には限定されない。しかも、この合成樹脂板は、合成樹脂に各種添加剤を加えたものからなる板材であってもよく、耐候性層等を設けることにより多層構造となった板材であってもよい。さらに、この合成樹脂板は、合成樹脂にガラス繊維等を含有させた強化樹脂からなる板材であってもよい。   The resin folded plate roofing material 4 is made of a synthetic resin plate having translucency, and the shape of the cross section along the vertical and horizontal directions is from the top of the peak 2a of the tight frame 2 through the valley to the adjacent peak 2a. It is formed in substantially the same uneven shape as the shape reaching the top. Here, translucency refers to the property of transmitting visible light and is not limited to being transparent. For example, it may transmit light while scattering it, or may absorb part of light. Good. In addition, as the synthetic resin plate, a plate material of polycarbonate resin or acrylic resin with high light transmittance is optimal, and other thermoplastic resins such as polyester resin and vinyl chloride resin are also suitably used. Is not limited. Moreover, the synthetic resin plate may be a plate material made of a synthetic resin with various additives added thereto, or may be a plate material having a multilayer structure by providing a weather resistant layer or the like. Further, the synthetic resin plate may be a plate material made of a reinforced resin containing glass fiber or the like in a synthetic resin.

なお、これらの金属折板屋根材3や樹脂折板屋根材4は、本実施形態のように左右方向に凹凸形状が1サイクル分だけが形成されたものに限らず、さらに多くの凹凸形状が形成されていてもよい。また、これらの金属折板屋根材3や樹脂折板屋根材4の前後方向の長さは、少なくとも2本の母屋材1の上に架け渡すことができる長さがあればよく、3本以上の母屋材1の上に架け渡すような長さがあってもよい。   In addition, these metal folded-plate roof materials 3 and resin folded-plate roof materials 4 are not restricted to what was uneven | corrugated shape only for 1 cycle in the left-right direction like this embodiment, Furthermore, many uneven | corrugated shapes are It may be formed. The length of the metal folded plate roofing material 3 and the resin folded plate roofing material 4 in the front-rear direction only needs to be long enough to be bridged on at least two main building materials 1, and three or more. There may be a length that spans over the main purlin 1 of the house.

上記金属折板屋根材3は、前後に並ぶ複数本の母屋材1の上に、左右に並べて載置される。この際、各金属折板屋根材3は、母屋材1の上に固着されたタイトフレーム2の山部2aの頂部と隣の山部2aの頂部との間の上に載置され、タイトフレーム2の各山部2aの頂部に取り付けられた前後に長尺な金属製の吊子5を介して、隣接する他の金属折板屋根材3と端部同士をかしめることにより連結される。また、これらの金属折板屋根材3は、1枚だけを上記樹脂折板屋根材4と置き替えて配置することにより、この部分を折板屋根の採光部としている。従って、この樹脂折板屋根材4も、左右の端部を吊子5を介して隣接する金属折板屋根材3の端部とそれぞれかしめることにより連結される。金属折板屋根材3や樹脂折板屋根材4は、このように端部同士を吊子5を介してかしめることにより水密構造となる。   The metal folded plate roofing material 3 is placed side by side on a plurality of purlins 1 arranged in front and rear. At this time, each metal folded plate roofing material 3 is placed between the top of the peak 2a of the tight frame 2 fixed on the purlin 1 and the top of the adjacent peak 2a. The other metal folded plate roofing materials 3 are connected by caulking the ends to each other via a long metal suspension 5 attached to the top of each peak portion 2a. Moreover, these metal folded-plate roof materials 3 replace only the said resin folded-plate roof material 4, and arrange | position this part as the lighting part of a folded-plate roof. Therefore, the resin folded plate roofing material 4 is also connected by caulking the left and right end portions with the end portions of the adjacent metal folded plate roofing material 3 via the suspension 5. The metal folded plate roofing material 3 and the resin folded plate roofing material 4 have a watertight structure by caulking the end portions with the suspension 5 in this manner.

ただし、図1の左側の吊子5は、金属折板屋根材3の端部同士ではなく、金属折板屋根材3の端部とは材質や厚さの異なる樹脂折板屋根材4の端部が覆うようにしてかしめられるので、通常の吊子5とは異なり、厚さの薄い金属製であり、前後に短いものをタイトフレーム2の山部2aごとに取り付けたものを用いている。しかも、この図1の左側の吊子5による金属折板屋根材3と樹脂折板屋根材4の端部同士のかしめ部は、水密構造を確実にするために、前後に長尺なアルミニウム板からなるキャップ部材で覆っている。   However, the left hanging element 5 in FIG. 1 is not the ends of the metal folded plate roofing material 3 but the ends of the resin folded plate roofing material 4 having a different material and thickness from the ends of the metal folded plate roofing material 3. Since it is caulked so as to cover the part, it is made of a metal having a small thickness, different from the normal hanging element 5, and a short thing attached to each peak part 2 a of the tight frame 2 is used. In addition, the caulked portion between the ends of the metal folded plate roofing material 3 and the resin folded plate roofing material 4 by the left hanging element 5 in FIG. 1 is an aluminum plate that is long in the front and rear directions in order to ensure a watertight structure. It is covered with a cap member made of

なお、金属折板屋根材3や樹脂折板屋根材4の水密構造は、必ずしも吊子5を介したかしめによるものに限らず、他の連結手段によって水密構造とすることもできる。また、樹脂折板屋根材4は、本実施形態のように1枚だけを金属折板屋根材3と置き替えるのではなく、連続する複数枚の金属折板屋根材3と置き替えたり、連続しない複数枚の金属折板屋根材3と置き替えるようにしてもよい。   In addition, the watertight structure of the metal folded plate roof material 3 or the resin folded plate roof material 4 is not necessarily limited to caulking via the suspension 5, but may be a watertight structure by other connecting means. Further, the resin folded plate roof material 4 is not replaced with the metal folded plate roof material 3 as in the present embodiment, but is replaced with a plurality of continuous metal folded plate roof materials 3 or continuously. You may make it replace with the several metal folded-plate roof material 3 which is not.

The tight frame 2 having two peak portions 2a shown in FIGS. 2 to 9 has a resin folded plate roof material 4 arranged between the tops of both peak portions 2a shown in FIG. Then, as shown in FIG. 2, two light-transmitting non-combustible plates 6 are arranged side by side in the left-right direction position of these tight frames 2 between the two purlins 1. Also, a left receiving member 7 and a right receiving member 8 are disposed on the left and right sides of the two light-transmitting non-combustible plates 6. And the front and rear receiving materials 9 are respectively arranged below the fixing positions of the tight frames 2 on the two purlins 1. Further, a front / rear joint receiving material 10 is disposed under the two light-transmitting non-combustible plates 6. Since FIG. 2 is an assembly drawing, all members other than the purlin material 1 are shown displaced upward.

透光不燃板6は、透光性を有する不燃材料からなる板状の透光不燃材であり、本実施形態では方形の網入りガラスからなる。なお、ここでの透光性も、樹脂折板屋根材4の場合と同じであり、透明も含む。   The translucent incombustible plate 6 is a plate-shaped translucent incombustible material made of a translucent incombustible material, and in the present embodiment, is made of a square netted glass. In addition, the translucency here is also the same as the case of the resin folded-plate roof material 4, and transparent is also included.

左側受材7は、前後の長さが2本の母屋材1の間とほぼ同じで、上下がタイトフレーム2の山部2aの高さより少し長いほぼ方形の金属板であり、上端部を右方向に直角に折り曲げると共に、この折り曲げた部分を前後方向にさらに突出させてそれぞれ係止部7aとしている。また、この左側受材7の下端部は、母屋材1との干渉を避けるために前後の隅部をそれぞれ切り欠くと共に、この前後を切り欠いた部分の下部を右方向に直角に折り曲げて支持部7bを形成している。前後の係止部7aは、母屋材1の上に固着したタイトフレーム2の山部2aに係止されるものであり、係止のための孔が形成されている。支持部7bは、2枚の透光不燃板6の左の端部をそれぞれ支持するものである。   The left receiving member 7 is a substantially rectangular metal plate whose front and rear length is substantially the same as that between the two purlins 1 and whose top and bottom are slightly longer than the height of the peak portion 2a of the tight frame 2, and the upper end is on the right side. The bent portions are bent at right angles to the direction, and the bent portions are further protruded in the front-rear direction to form locking portions 7a. Moreover, in order to avoid interference with the purlin 1, the lower end portion of the left-side receiving member 7 is cut out at the front and rear corners, and the lower portion of the cut-out portion is bent at right angles to the right and supported. Part 7b is formed. The front and rear locking portions 7a are locked to the peak portions 2a of the tight frame 2 fixed on the purlin member 1, and holes for locking are formed. The support part 7b supports the left end part of the two translucent incombustible plates 6, respectively.

右側受材8も、前後の長さが2本の母屋材1の間とほぼ同じで、上下がタイトフレーム2の山部2aの高さより少し長いほぼ方形の金属板である。そして、上端部を左方向に直角に折り曲げると共に、この折り曲げた部分を前後方向にさらに突出させてそれぞれ係止部8aとしている。また、この右側受材8の下端部は、母屋材1との干渉を避けるために前後の隅部をそれぞれ切り欠くと共に、この前後を切り欠いた部分の下部を左方向に直角に折り曲げて支持部8bを形成している。前後の係止部8aは、母屋材1の上に固着したタイトフレーム2の山部2aに係止されるものであり、係止のための孔が形成されている。支持部8bは、2枚の透光不燃板6の右の端部をそれぞれ支持するものである。   The right receiving member 8 is also a substantially rectangular metal plate whose front and rear length is substantially the same as that between the two purlins 1 and whose top and bottom are slightly longer than the height of the peak portion 2 a of the tight frame 2. Then, the upper end portion is bent at a right angle in the left direction, and the bent portion is further protruded in the front-rear direction to form a locking portion 8a. Further, the lower end portion of the right receiving member 8 is notched at the front and rear corners in order to avoid interference with the purlin material 1, and is supported by bending the lower portion of the notched portion at a right angle to the left. Part 8b is formed. The front and rear locking portions 8a are locked to the peak portions 2a of the tight frame 2 fixed on the purlin member 1, and holes for locking are formed. The support part 8b supports the right end part of the two translucent incombustible plates 6, respectively.

上記左側受材7と右側受材8は、軽量化を図るためにアルミニウムやアルミニウム合金の板材を用いることが好ましい。また、鉄板でもよく、耐食性を重視する場合にはステンレス綱板を用い、耐火性を重視する場合には鋼板を用いればよい。さらに、これらの左側受材7と右側受材8は、本実施形態のようなほぼ方形である必要はなく、上部から前後方向にそれぞれ突出する係止部7a,8aが形成されると共に、下部からは互いに向かい合う左右の方向に突出する支持部7b,8bが形成されていればよい。そして、係止部7a,8aは、タイトフレーム2の山部2aに係止するために、この山部2aの平坦部等の構成に対応した適宜構造のものでよく、支持部7b,8bも、透光不燃板6を支持するために、例えば適所に数箇所のみ突出させる等の適宜構造のものでよい。しかも、これらの左側受材7と右側受材8は、板状である必要もなく、例えば細長い金属板や金属棒を方形の縁部にのみ配置したりトラス構造状に配置したものであってもよい。   The left receiving member 7 and the right receiving member 8 are preferably made of aluminum or an aluminum alloy plate in order to reduce the weight. Further, an iron plate may be used, and a stainless steel plate is used when emphasizing corrosion resistance, and a steel plate may be used when emphasizing fire resistance. Further, the left receiving member 7 and the right receiving member 8 do not need to be substantially rectangular as in the present embodiment, and are formed with locking portions 7a and 8a that protrude from the upper part in the front-rear direction, and the lower part. Need only be formed with support portions 7b, 8b protruding in the left and right directions facing each other. The locking portions 7a and 8a may be of an appropriate structure corresponding to the configuration of the flat portion or the like of the peak portion 2a in order to be locked to the peak portion 2a of the tight frame 2, and the support portions 7b and 8b are also provided. In order to support the translucent incombustible plate 6, for example, it may have an appropriate structure such as protruding only at a few places in place. In addition, the left receiving member 7 and the right receiving member 8 do not have to be plate-like, for example, an elongated metal plate or a metal rod is arranged only at the edge of a square or arranged in a truss structure. Also good.

前後受材9は、左右方向の長さが上記左側受材7と右側受材8との間隔とほぼ等しい方形の金属板を、開口部が下方に向く横断面コの字形状に折り曲げたものであり、前側の下部をさらに前方に直角に折り曲げて突出させると共に、後側の下部をさらに後方に直角に折り曲げて突出させることによりそれぞれ支持部9aが形成されている。前後の支持部9aは、後方の透光不燃板6の後の端部と前方の透光不燃板6の前の端部をそれぞれ支持するものである。この前後受材9は、母屋材1における上記左側受材7と右側受材8との間の左右位置に、この母屋材1の上を前後に跨ぐように載置されて溶接等によって固着される。   The front / rear receiving material 9 is formed by bending a rectangular metal plate having a lateral length substantially equal to the distance between the left receiving material 7 and the right receiving material 8 into a U-shaped cross section with the opening facing downward. The lower portions on the front side are further bent forward at a right angle and protruded, and the lower portions on the rear side are further bent at a right angle and protruded rearward to form the support portions 9a. The front and rear support portions 9a support the rear end portion of the rear translucent incombustible plate 6 and the front end portion of the front translucent noncombustible plate 6, respectively. The front and rear receiving members 9 are placed on the left and right positions between the left receiving member 7 and the right receiving member 8 in the main building material 1 so as to straddle the main building material 1 and are fixed by welding or the like. The

上記前後受材9は、母屋材1の上を前後に跨ぐように配置されるものであれば、必ずしも方形の金属板を横断面コの字形状に折り曲げたものには限らず、例えば細長い金属板や金属棒を用いて母屋材1の上を前後に跨ぐように配置することができるように構成した金属製の枠体等であってもよい。また、支持部9aも、前後受材9の前後に跨いだ下部から前後に突出するものであれば、例えば適所に数箇所のみ突出させる等の適宜構造のものでよい。さらに、前後受材9は、透光不燃板6を前後で支持するものであるから、透光不燃板6の支持は左右の左側受材7と右側受材8だけに任せて、この前後受材9の使用を省略することもできる。   As long as the said front-and-rear receiving material 9 is arrange | positioned so that the top of the main building material 1 may be straddled back and forth, it does not necessarily need to be a thing which bent the square metal plate into the U-shaped cross section, for example, elongate metal The metal frame etc. which were comprised so that it could arrange | position so that it might straddle on the front and back materials 1 using the board and the metal rod may be sufficient. Further, the support portion 9a may also have an appropriate structure, for example, if it protrudes forward and backward from the lower portion straddling the front and rear of the front and rear receiving material 9, for example, only a few locations protrude at appropriate positions. Further, since the front and rear receiving material 9 supports the translucent incombustible plate 6 in the front and rear directions, the support of the translucent incombustible plate 6 is left to the left and right left receiving materials 7 and the right receiving material 8 only. The use of the material 9 can also be omitted.

前後ジョイント受材10は、左右方向の長さが上記左側受材7と右側受材8との間隔とほぼ等しい左右に長尺な金属材からなる。また、この左右に長尺な横断面が逆T字形状であるため、この逆T字形状による下部の水平部が前後方向にそれぞれ突出する支持部10aとなる。この前後ジョイント受材10は、2枚の透光不燃板6の間に配置して、前後の支持部10aによりこれらの透光不燃板6の前後で隣り合う側の端部を支持するものである。   The front-rear joint receiver 10 is made of a metal material that is long in the left-right direction and whose length in the left-right direction is substantially equal to the distance between the left-side receiver 7 and the right-side receiver 8. In addition, since the lateral cross section that is long to the left and right is an inverted T shape, the lower horizontal portion of the inverted T shape is a support portion 10a that protrudes in the front-rear direction. This front / rear joint receiving material 10 is disposed between two translucent incombustible plates 6 and supports the end portions on the sides adjacent to each other before and after these translucent incombustible plates 6 by front and rear support portions 10a. is there.

上記前後ジョイント受材10は、必ずしも横断面が逆T字形状である必要はなく、例えば単に左右に細長い水平な金属板であってもよい。この場合、金属板の前方側と後方側がそれぞれ支持部10aとなる。また、前後ジョイント受材10は、2枚の透光不燃板6の隣り合う側の端部を支持するものであるから、この前後ジョイント受材10の使用を省略することもでき、特に透光不燃板6が前後に2枚に分割されることなく、1枚ものの網入りガラスである場合には、使用の必要がない。   The front / rear joint receiver 10 does not necessarily have an inverted T-shaped cross section, and may be a horizontal metal plate that is simply elongated to the left and right, for example. In this case, the front side and the rear side of the metal plate are the support portions 10a, respectively. Moreover, since the front-rear joint receiving material 10 supports the end portions on the adjacent side of the two light-transmitting non-combustible plates 6, the use of the front-rear joint receiving material 10 can be omitted. When the non-combustible plate 6 is not divided into two pieces before and after and is a single piece of netted glass, there is no need to use it.

〔透光不燃板の施工手順〕
上記透光不燃板6と受材7〜10の施工手順の一例を図3〜図8に基づいて説明する。
[Procedure for translucent incombustible plate]
An example of the construction procedure of the translucent incombustible plate 6 and the receiving materials 7 to 10 will be described with reference to FIGS.

図3に示すように、各母屋材1には、まず前後受材9を載置して固着する。そして、図4に示すように、この前後受材9を固着した母屋材1の上にタイトフレーム2を載置して、このタイトフレーム2の谷部を前後受材9や母屋材1に固着する。なお、タイトフレーム2と前後受材9は、通常は溶接によって固着されるが、この固着手段は任意であり、例えばねじ止めによってタイトフレーム2と前後受材9を一括して母屋材1に固着することもできる。   As shown in FIG. 3, first, the front and rear receiving materials 9 are first placed and fixed on each main building material 1. Then, as shown in FIG. 4, the tight frame 2 is placed on the purlin member 1 to which the front and rear receiving materials 9 are fixed, and the valleys of the tight frame 2 are fixed to the front and rear receiving materials 9 and the main purlin material 1. To do. The tight frame 2 and the front and rear receiving materials 9 are usually fixed by welding, but this fixing means is arbitrary. For example, the tight frame 2 and the front and rear receiving materials 9 are collectively fixed to the main building material 1 by screwing. You can also

上記のようにして2本の母屋材1の上に固着した前後のタイトフレーム2の各山部2aの間には、図5に示すように、左側受材7と右側受材8が係止される。即ち、左側受材7は、前後の係止部7aをそれぞれ前後のタイトフレーム2の左側の山部2aに形成された平坦部に載置すると共に、右側受材8は、前後の係止部8aをそれぞれ前後のタイトフレーム2の右側の山部2aに形成された平坦部に載置することにより、これら前後のタイトフレーム2の間に架け渡すように配置される。また、この際、左側受材7と右側受材8の支持部7b,8bの前後の端部は、前後受材9の支持部9aの左右の端部と重なるので、この部分をリベットでかしめることにより固着する。なお、この支持部7b,8bと支持部9aの固着手段は、リベットには限定されず、また、必ずしも固着する必要もない。   As shown in FIG. 5, the left receiving member 7 and the right receiving member 8 are locked between the front and rear peak portions 2a of the tight frame 2 fixed on the two purlins 1 as described above. Is done. That is, the left receiving member 7 places the front and rear engaging portions 7a on the flat portions formed on the left ridges 2a of the front and rear tight frames 2, and the right receiving member 8 includes the front and rear engaging portions. 8a is placed on the flat part formed on the right peak part 2a of the front and rear tight frames 2, respectively, and is arranged so as to be bridged between the front and rear tight frames 2. At this time, the front and rear ends of the support portions 7b and 8b of the left receiving member 7 and the right receiving member 8 overlap with the left and right end portions of the supporting portion 9a of the front and rear receiving member 9, so It is fixed by tightening. The fixing means for the support portions 7b and 8b and the support portion 9a is not limited to rivets, and is not necessarily fixed.

図6に示すように、上記左側受材7と右側受材8の間の前後の中央部には、前後ジョイント受材10が係止される。即ち、この前後ジョイント受材10は、左の端部を左側受材7の支持部7bに載置して、この支持部7bと前後ジョイント受材10の支持部10aとをリベットでかしめると共に、右の端部を右側受材8の支持部8bに載置して、この支持部8bと前後ジョイント受材10の支持部10aとをリベットでかしめることにより固着する。なお、この前後ジョイント受材10の固着手段は、リベットに限らず任意であり、固着することなく、単に前後ジョイント受材10を載置するだけでもよい。   As shown in FIG. 6, the front and rear joint receiver 10 is locked at the front and rear central portions between the left receiver 7 and the right receiver 8. That is, the front / rear joint receiver 10 has the left end placed on the support 7b of the left receiver 7 and rivets the support 7b and the support 10a of the front / rear joint receiver 10 with rivets. The right end portion is placed on the support portion 8b of the right receiving member 8, and the support portion 8b and the supporting portion 10a of the front and rear joint receiving member 10 are fixed by rivets. The fixing means for the front / rear joint receiver 10 is not limited to a rivet, and any means may be used, and the front / rear joint receiver 10 may simply be placed without fixing.

上記により、左側受材7と右側受材8との間は、これら左側受材7と右側受材8の支持部7b,8bと、前後受材9の支持部9aと、前後ジョイント受材10の支持部10aとによって四方を囲まれた前後2箇所の領域が形成される。そして、図7に示すように、これら左側受材7と右側受材8との間の2箇所の領域に透光不燃板6がそれぞれ載置される。また、これら2枚の透光不燃板6は、それぞれ四隅の支持部7b,8b,9a,10aとの境界付近にコーキング剤を塗布することにより止め付ける。なお、このコーキング剤の塗布に代えて、予め支持部7b,8b,9a,10a上にパッキン剤を塗布しておき、この上に透光不燃板6を載置することにより止め付けてもよい。ただし、透光不燃板6は、これらの支持部7b,8b,9a,10aに支持されていればよく、水密構造は特に必要ないので、振動等の心配がなければ、コーキング剤やパッキン剤等は不要である。   As described above, between the left receiving member 7 and the right receiving member 8, the support portions 7 b and 8 b of the left receiving member 7 and the right receiving member 8, the supporting portion 9 a of the front and rear receiving member 9, and the front and rear joint receiving member 10. The front and rear two regions surrounded by the four sides are formed by the support portion 10a. And as shown in FIG. 7, the translucent incombustible board 6 is each mounted in the area | region of two places between these left side receiving materials 7 and the right side receiving materials 8. As shown in FIG. Moreover, these two translucent incombustible plates 6 are stopped by applying a caulking agent in the vicinity of the boundaries with the support portions 7b, 8b, 9a and 10a at the four corners, respectively. Instead of applying the caulking agent, a packing agent may be applied in advance on the support portions 7b, 8b, 9a, and 10a, and the translucent incombustible plate 6 may be placed thereon to be stopped. . However, the translucent incombustible plate 6 is only required to be supported by these support portions 7b, 8b, 9a, 10a, and a watertight structure is not particularly required. Is unnecessary.

上記では2本の母屋材1の間の施工手順を示したが、さらに多数の母屋材1の上に樹脂折板屋根材4を架け渡す場合には、図8に示すように、これらの母屋材1のそれぞれの間に、上記と同様に受材7〜10と透光不燃板6を取り付ける。この際、タイトフレーム2の山部2aの平坦部上には、前後の左側受材7や右側受材8の係止部7a,8aが2枚重なって載置される。そして、これら2枚の係止部7a,8aの孔を通して山部2aの平坦部に穿設したねじ孔にボルト11を螺着することにより、左側受材7と右側受材8が前後のタイトフレーム2の山部2aに係止固定される。また、前後の端の母屋材1の上に固着したタイトフレーム2の場合や、2本の母屋材1の上にのみ樹脂折板屋根材4を架け渡す場合には、このタイトフレーム2の山部2aの平坦部上には1枚の係止部7a又は係止部8aのみが載置されるが、これらの場合も同様にボルト11を螺着することにより係止固定する。なお、これら左側受材7と右側受材8の係止部7a,8aの係止手段は任意であり、ボルト11以外の係止手段によって係止してもよく、タイトフレーム2の山部2aの平坦部以外に係止することもできる。   Although the construction procedure between the two purlins 1 has been described above, when the resin folded plate roofing material 4 is bridged over a large number of purlins 1, as shown in FIG. Between each of the materials 1, the receiving materials 7 to 10 and the translucent incombustible plate 6 are attached in the same manner as described above. At this time, on the flat portion of the peak portion 2a of the tight frame 2, the front and rear left receiving members 7 and the engaging portions 7a and 8a of the right receiving member 8 are placed in an overlapped manner. Then, by screwing the bolt 11 into the screw hole formed in the flat portion of the peak portion 2a through the holes of the two locking portions 7a and 8a, the left receiving member 7 and the right receiving member 8 are tightly attached to the front and rear. It is locked and fixed to the peak portion 2 a of the frame 2. In the case of the tight frame 2 fixed on the front and rear purlins 1 or when the resin folded plate roof material 4 is bridged only on the two purlins 1, Only one locking portion 7a or locking portion 8a is placed on the flat portion of the portion 2a. In these cases, the bolts 11 are similarly screwed and fixed. The locking means of the locking portions 7a, 8a of the left receiving material 7 and the right receiving material 8 is arbitrary, and may be locked by locking means other than the bolt 11, or the peak portion 2a of the tight frame 2. It can also be locked to other than the flat part.

上記のようにして受材7〜10による透光不燃板6の支持が完了すると、2本以上の母屋材1の上に1枚の樹脂折板屋根材4とその左右に複数枚の金属折板屋根材3が載置され、図1に示すように、これらの金属折板屋根材3や樹脂折板屋根材4の端部を吊子5を介してかしめて連結することにより、折板屋根の施工が完了する。ただし、吊子5は、上記ボルト11によってタイトフレーム2の山部2aの平坦部に固着するので、実際には、この山部2aの平坦部には、左側受材7や右側受材8の係止部7a,8aだけでなく、この吊子5の下端部も載置され、ボルト11によってまとめて固着される。   When the support of the translucent incombustible plate 6 by the receiving materials 7 to 10 is completed as described above, one resin folded plate roof material 4 on the two or more purlin materials 1 and a plurality of metal folded plates on the left and right sides thereof. The plate roof material 3 is placed, and as shown in FIG. 1, the ends of the metal folded plate roof material 3 and the resin folded plate roof material 4 are caulked and connected via a suspension 5, thereby folding the plate. The construction of the roof is completed. However, since the hanger 5 is fixed to the flat portion of the peak portion 2a of the tight frame 2 by the bolt 11, in fact, the left receiving member 7 and the right receiving member 8 are not attached to the flat portion of the peak portion 2a. Not only the locking portions 7a and 8a but also the lower end portion of the suspension 5 is placed and fixed together by the bolt 11.

上記構成により、左側受材7や右側受材8等の受材7〜10を用いて透光不燃板6を樹脂折板屋根材4の下方に支持することができるので、飛び火によって合成樹脂からなる樹脂折板屋根材4に孔があいても、この孔を通り抜けた飛び火や溶融した樹脂が屋内に入るのを不燃材料からなる透光不燃板6によって確実に防ぐことができ、防火安全性を確保することができる。例えば、透光不燃板6として網入りガラスを用い受材7〜10として鋼板を用いた場合には、建築基準法第2条第7号の耐火構造に該当し、透光不燃板6と受材7〜10がその他の材料も、少なくとも同条第9号の不燃材料に該当する。   With the above configuration, the translucent incombustible plate 6 can be supported below the resin folded plate roof material 4 using the receiving materials 7 to 10 such as the left receiving material 7 and the right receiving material 8. Even if there is a hole in the resin folded plate roof material 4, it is possible to reliably prevent flying fire that has passed through the hole or molten resin from entering the room by the light-transmitting non-combustible plate 6 made of a non-combustible material. Can be secured. For example, when a glass-filled glass is used as the translucent incombustible plate 6 and a steel plate is used as the receiving materials 7 to 10, it corresponds to the fireproof structure of Article 2, Item 7 of the Building Standards Act, and the translucent incombustible plate 6 The other materials of materials 7 to 10 correspond to at least the non-combustible material of the same article No. 9.

しかも、樹脂折板屋根材4は、金属折板屋根材3と共に取り付けた樹脂折板屋根材4の下方に配置されるので、水密構造を考慮する必要がなく、受材7〜10による簡単な構造で施工も容易となる。   Moreover, since the resin folded plate roofing material 4 is disposed below the resin folded plate roofing material 4 attached together with the metal folded plate roofing material 3, it is not necessary to consider a watertight structure, and the receiving members 7 to 10 are simple. Construction is easy due to the structure.

また、透光不燃板6は、左側受材7や右側受材8の支持部7b,8bだけでなく、前後受材9の支持部9aによっても確実に支持される。さらに、この透光不燃板6は、前後に2分割されて、分割部が前後ジョイント受材10の支持部10aで支持されるので、網入りガラスのサイズを小さくして安定して支持することができるようになる。さらに、この透光不燃板6は、網入りガラスからなるので、透光性は有するものの不透明な他の透光不燃材よりも光透過率が高くなり、樹脂折板屋根材4から入り込んだ光を効率良く屋内に取り込むことができる。しかも、網入りガラスは、何らかの原因で破損したとしても、ガラス破片が飛散したり脱落するようなことがないので、屋根構造の安全性を向上させることもできる。   Further, the translucent incombustible plate 6 is reliably supported not only by the support portions 7 b and 8 b of the left receiving material 7 and the right receiving material 8 but also by the support portions 9 a of the front and rear receiving materials 9. Furthermore, since the translucent incombustible plate 6 is divided into two parts in the front and rear, and the divided part is supported by the support part 10a of the front and rear joint receiving material 10, the size of the meshed glass is reduced and stably supported. Will be able to. Further, since the light-transmitting non-flammable plate 6 is made of meshed glass, the light transmittance is higher than that of other light-transmitting non-flammable materials that have translucency, but light that has entered from the resin folded-plate roofing material 4. Can be taken indoors efficiently. Moreover, even if the glass with a mesh breaks for some reason, the glass fragments do not scatter or fall off, so that the safety of the roof structure can be improved.
