Description

本発明は、主に馳締タイプ及び嵌合キャップ材を使用した嵌合タイプの折板屋根板にて施工される屋根を構成する屋根用受具及びその折板屋根に関する。 The present invention relates to a roof support that constitutes a roof constructed mainly with fastening type and fitting type folded roof panels using fitting cap material, and the folded roof.

近年、種々の金属製の折板タイプの屋根板材が多く使用された屋根（急傾斜状の壁等も含む）が施工されている。この種の屋根用板は、母屋，胴縁等の構造材に屋根用受具を介して固定されているものであり、前記屋根用板同士の連結構造として、馳締タイプ及びキャップ材を使用した嵌合タイプのものが存在し、これらのタイプのものが多く使用されている。また、折板屋根では、急傾斜に施工された略壁面状としたものも存在し、このような折板屋根も多く存在している。 In recent years, roofs (including steeply sloping walls, etc.) have been constructed using a wide variety of metal folded-plate roofing materials. This type of roofing plate is fixed to structural materials such as purlins and furring strips via roof supports, and the connecting structures between the roofing plates include a fastening type and a fitting type using a cap material, and these types are widely used. There are also folded-plate roofs that are constructed at a steep slope to resemble a wall, and many such folded-plate roofs exist.

これらの馳締タイプの屋根用板にて施工された屋根では、屋根用板同士の連結は、馳締部と屋根用受具の頂部に固着される吊子を介して行われる。つまり、馳締タイプの屋根は、吊子と、屋根用板の馳締部同士との連結のみで、屋根用板が屋根用受具に固定される構成となっている。 In roofs constructed with these fastening-type roof panels, the panels are connected to each other via retaining clips that are fixed to the fastening parts and the tops of the roof supports. In other words, a fastening-type roof is configured so that the roof panels are fixed to the roof supports only by connecting the retaining clips to the fastening parts of the roof panels.

ところが、それぞれの屋根用板に風による負圧が作用したときに、その平坦面が広ければ広いほど、大きな負圧外力が作用し、屋根用板は上方に持ち上げられるような力がかかる。そして、近年では、自然環境の変化により大型且つ強力な台風が増加し、その規模も強大となる傾向にある。 However, when negative pressure from the wind acts on each roof board, the larger the flat surface, the greater the negative external pressure force that acts, and the roof board is lifted upward. In recent years, due to changes in the natural environment, the number of large and powerful typhoons has increased, and they tend to be larger in scale.

そのために、屋根では、屋根用板同士の馳締連結部が屋根用受具から屋根用板が外れて飛ばされてしまうという状況が以前よりも増加する傾向にあり、屋根の耐久性を向上させることがより一層強く求められることになった。そこで、受金具には、吊子と共に屋根用板を強固に固定するために工夫が行われている。このような強風による負圧対策は、前述した馳締タイプの折板屋根と共に、嵌合キャップ材を使用する嵌合タイプの折板屋根に対しても要求されている。 As a result, there has been an increasing tendency for roof panels to be blown away by the roof brackets at the joints between the panels, creating a greater need to improve the durability of roofs. To address this issue, the brackets have been designed to firmly secure the panels together with the retaining clips. This type of measure against negative pressure caused by strong winds is required not only for the aforementioned fastened type folded plate roofs, but also for interlocking type folded plate roofs that use interlocking cap materials.

屋根を構成する屋根用板が、強風による負圧にて破損することを防止するための具体的な対策の一例として、馳締部等の連結箇所以外の部分で屋根用受具に屋根用板を固定する構造としたものが存在する。その具体例として特許文献１を挙げる。特許文献１を概説する。なお、符号は特許文献１に使用されたものをそのまま使用する。 One example of a specific measure to prevent roof panels that make up a roof from being damaged by negative pressure caused by strong winds is a structure in which the roof panels are fixed to the roof bracket at a location other than the connection points such as the fastening parts. Patent Document 1 is cited as a specific example. An overview of Patent Document 1 is given below. The reference numerals used in Patent Document 1 are used as they are.

特許文献１には、屋根材取付部(3)と脚部(1)が開示されている。折板屋根材(10)の側部の上下方向中間に係止部(12)が形成されている。また、タイトフレーム(T)には、折板同士の馳締部を支持固定するハゼ受部(6)が具備されている。この特許文献１に見られるように近年では、馳締タイプの屋根用板には、馳締部以外に被係止部が形成され、タイトフレーム（屋根用受具）は、馳締連結部と共に被係止部でも屋根用板が固定される構成としたもの多く使用されている。 Patent Document 1 discloses a roof material mounting part (3) and a leg part (1). A locking part (12) is formed in the vertical middle of the side part of the folded plate roof material (10). The tight frame (T) is also equipped with a seam receiving part (6) that supports and fixes the fastening part between the folded plates. As seen in Patent Document 1, in recent years, fastening type roof plates are formed with an engaged part in addition to the fastening part, and tight frames (roof supports) are often used that are configured so that the roof plate is fixed not only to the fastening connection part but also to the engaged part.

ところで、特許文献１では、屋根材取付部(3)は、立方体状の箱の開口を下向きにしたような形状であり、該屋根材取付部(3)の外周の対向する一辺を係止受部(5)としたものである。そして、前述したように、近年気象環境が大きく変化し、台風も発生も増加し、しかも大型化している状況にある。 In Patent Document 1, the roofing material mounting part (3) is shaped like a cubic box with the opening facing downward, and one opposing side of the outer periphery of the roofing material mounting part (3) serves as the locking receiving part (5). As mentioned above, the weather environment has changed significantly in recent years, and the occurrence of typhoons has increased, and they are also becoming larger.

そのため、特許文献１における屋根材取付部(3)の係止受部(5)の領域は小さく、折板屋根材(10)の係止部(12)との係止範囲も狭くなり、その係止状態は必ずしも万全とは言えず、強風によって係止受部(5)と係止部(12)とが外れてしまうおそれは十分にある。さらに、特許文献１では、屋根材取付部(3)と脚部(2)が別部材とした実施形態においては、ボルト締めにて接合されていることが開示されている。そして、このような金属部品同士の接合手段として、上記のようにボルト締めとしたものや、溶接としたものが一般的に行われている。 Therefore, the area of the locking receiving portion (5) of the roof material mounting portion (3) in Patent Document 1 is small, and the range of engagement with the locking portion (12) of the folded plate roof material (10) is also narrow, so the locking state cannot be said to be perfect, and there is a possibility that the locking receiving portion (5) and the locking portion (12) may come off due to strong winds. Furthermore, Patent Document 1 discloses that in an embodiment in which the roof material mounting portion (3) and the leg portion (2) are separate members, they are joined by bolting. And, as a means of joining such metal parts together, the above-mentioned bolting and welding are generally used.

しかし、ボルトによる接合又は溶接による接合も、その構造によっては十分な接合が行われず、前述したような、台風等による大きな負圧荷重には、ボルトや溶接では耐えられず、屋根板と共に脚部(2)から屋根材取付部(3)が外れてしまうことも十分に有り得る。また、溶接による接合は、その作業時に、高温により、脚部(2)から屋根材取付部(3)に対して変形を生じさせるおそれも十分にあり、溶接範囲を最小にしなければならない。しかし、溶接範囲を最小にすると、十分な接合力を得ることはできないという、相反する状態になる。そこで、本発明の目的は、強風によって折板屋根板が受具から極めて外れ難く、優れた耐久性を有する屋根用受具及びその折板屋根を提供することにある。 However, depending on the structure, bolted or welded joints may not provide sufficient joints, and as mentioned above, bolts and welds cannot withstand large negative pressure loads caused by typhoons, etc., and it is quite possible that the roof material attachment part (3) will come off the leg (2) along with the roof plate. In addition, welding joints are likely to cause deformation of the roof material attachment part (3) from the leg (2) due to high temperatures during the work, so the welding area must be minimized. However, minimizing the welding area creates a contradictory situation in which sufficient joining strength cannot be obtained. Therefore, the object of the present invention is to provide a roof support and a folded plate roof that are extremely unlikely to come off the support due to strong winds and have excellent durability.

そこで、発明者は上記課題を解決すべく鋭意，研究を重ねた結果、請求項１の発明を、長方形状で幅方向両端に嵌合端部としたベース板状部と該ベース板状部上に形成され下方に開口を有し、吊子装着用孔が形成された長方形状の膨出部とを備えた嵌合取付部材と、平坦状の面で接合用孔と該接合用孔箇所の下面に内ネジ部材が溶接固着された受頂部を有する受本体とを備え、前記受頂部が前記膨出部内に収容可能とされ、前記嵌合取付部材の前記膨出部は、膨出段差立上り面部の一方側に前記吊子装着用孔を有する膨出低位頂部が形成され他方側に膨出高位頂部が形成され、前記受本体の前記受頂部は、受段差立上り面部の一方側に前記接合用孔及び前記内ネジ部材を有する受低位頂部が形成され他方側に受高位頂部が形成され、前記膨出低位頂部には前記受低位頂部が収容され、前記膨出高位頂部には前記受高位頂部が収容され、溶接固着の位置は、前記膨出高位頂部と前記受高位頂部との接触面としてなることを特徴とする屋根用受具としたことにより、上記課題を解決した。 Therefore, the inventors have conducted intensive research to solve the above problems, and as a result, have developed the invention of claim 1 as a fitting attachment member comprising a rectangular base plate portion having fitting ends at both widthwise ends, a rectangular bulge portion formed on the base plate portion, having an opening at the bottom, and having a retaining clip attachment hole, and a receiving body having a flat surface with a joint hole and a receiving top portion with an internal thread member welded to the underside of the joint hole, the receiving top portion being capable of being accommodated within the bulge portion, and the bulge portion of the fitting attachment member having a front end on one side of the bulge step rising surface portion. The above problem was solved by providing a roof support that is characterized in that a bulging low-level top having a hole for attaching the retaining clip is formed on one side and a bulging high-level top is formed on the other side, and the top of the support body has a low-level top having the connection hole and the internal screw member on one side of the support step rising surface and a high-level top on the other side, the low-level top is accommodated in the bulging low-level top, and the high-level top is accommodated in the bulging high-level top, and the welding and fixing position is the contact surface between the bulging high-level top and the high-level top.

請求項３の発明を、長方形状で幅方向両端に嵌合端部としたベース板状部と該ベース板状部上に形成され下方に開口を有し、吊子装着用孔が形成された長方形状の膨出部とを備えた嵌合取付部材と、平坦状の面で接合用孔と該接合用孔箇所の下面に内ネジ部材が溶接固着された受頂部を有する受本体とを備え、前記受頂部が前記膨出部内に収容可能とされ、前記嵌合取付部材の前記膨出部は、膨出段差立上り面部の一方側に前記吊子装着用孔を有する膨出低位頂部が形成され他方側に膨出高位頂部が形成され、前記受本体の前記受頂部は、受段差立上り面部の一方側に前記接合用孔及び前記内ネジ部材を有する受低位頂部が形成され他方側に受高位頂部が形成され、前記膨出低位頂部には前記受低位頂部が収容され、前記膨出高位頂部には前記受高位頂部が収容され、溶接固着の位置は、前記膨出高位頂部と前記受高位頂部との接触面としてなる屋根用受具と、主板の幅方向両側より立上り部が形成され、幅方向一方の立上り部の上端に連結頂部が形成され、且つ両前記立上り部の高さ方向中間箇所には被嵌合屈曲部が形成された折板屋根板を備え、前記屋根用受具上に隣接する前記折板屋根板の被嵌合屈曲部が前記嵌合取付部材に嵌合されてなることを特徴とする折板屋根としたことにより、上記課題を解決した。 The invention of claim 3 is a fitting attachment member having a rectangular base plate portion with fitting ends at both ends in the width direction, a rectangular bulge portion formed on the base plate portion, with an opening at the bottom, and a retaining clip attachment hole, and a receiving body having a flat surface with a joint hole and a receiving top portion with an internal screw member welded to the underside of the joint hole, the receiving top portion being capable of being accommodated within the bulge portion, the bulge portion of the fitting attachment member having a bulge lower top portion with the retaining clip attachment hole on one side of the bulge step rising surface portion and a bulge higher top portion on the other side, the receiving top portion of the receiving body having the joint hole and the internal screw member on one side of the receiving step rising surface portion. The above problem was solved by providing a folded plate roof with a roof support that is formed on a lower receiving top and a higher receiving top on the other side, the lower receiving top is accommodated in the bulging lower receiving top, and the higher receiving top is accommodated in the bulging higher receiving top, and the welding and fixing position is the contact surface between the bulging higher receiving top and the higher receiving top, and a folded plate roof plate with rising parts formed on both sides of the width of the main plate, a connecting top formed at the upper end of one of the rising parts in the width direction, and a fitted bent part formed at the middle point of both the rising parts in the height direction, and the fitted bent part of the folded plate roof plate adjacent to the roof support is fitted into the fitting mounting member.

請求項４の発明を、請求項３に記載の折板屋根において、前記折板屋根板は主板の幅方向両側より立上り部が形成され、幅方向一方の立上り部の上端に下馳部が形成され他方の立上り部の上端に上馳部が形成され、幅方向に隣接する折板屋根板の下馳部と上馳部とが、馳締吊子を介して馳締されてなることを特徴とする折板屋根としたことにより、上記課題を解決した。 The invention of claim 4 solves the above problem by providing a folded plate roof as described in claim 3, characterized in that the folded plate roof panels have rising sections formed on both sides of the main plate in the width direction, a lower run section is formed at the upper end of one rising section in the width direction and an upper run section is formed at the upper end of the other rising section, and the lower run section and the upper run section of adjacent folded plate roof panels in the width direction are fastened together via a fastening clip.

請求項１の発明では、長方形状で幅方向両端に嵌合端部としたベース板状部と該ベース板状部上に形成され下方に開口を有し、吊子装着用孔が形成された長方形状の膨出部とを備えた嵌合取付部材と、平坦状の面で接合用孔と該接合用孔箇所の下面に内ネジ部材が溶接固着された受頂部を有する受本体とを備え、前記受頂部が前記膨出部内に収容可能とされ、前記受頂部の平坦状面と前記膨出部の下面との接触面同士が溶接される構成としたものである。 The invention of claim 1 is a fitting attachment member that includes a rectangular base plate portion with fitting ends at both ends in the width direction, a rectangular bulge portion formed on the base plate portion with an opening at the bottom and a retaining clip attachment hole, and a receiving body that has a flat surface with a receiving top portion with a joining hole and an internal thread member welded to the underside of the joining hole, the receiving top portion can be accommodated within the bulge portion, and the contact surfaces between the flat surface of the receiving top portion and the underside of the bulge portion are welded to each other.

上記構成により、受本体の受頂部が、嵌合取付部材の膨出部内に収容可能であり、嵌合取付部材と受本体との接触面同士が溶接され、受頂部に形成された接合用孔と、受頂部下面側で且つ前記接合用孔箇所に溶接固着された内ネジ部材とにより、折板屋根の施工において、吊子等の屋根施工に必要な部品が前記内ネジ部材を介してボルト締めされる構成とした。これによって、内ネジ部材が受頂部下面側に溶接固着され、前記吊子がボルト締めされ、且つ嵌合取付部材の膨出部と、受本体の受頂部とが溶接固着部にて固着されることで、本発明の屋根用受具は、極めて強固な構造にできる。 With the above configuration, the top of the receiving body can be accommodated within the bulge of the fitting attachment member, the contact surfaces of the fitting attachment member and the receiving body are welded together, and the connection hole formed in the receiving top and the internal thread member welded and fixed to the underside of the receiving top at the connection hole location allow parts required for roof construction such as retaining clips to be bolted via the internal thread member during construction of a folded plate roof. As a result, the internal thread member is welded and fixed to the underside of the receiving top, the retaining clip is bolted, and the bulge of the fitting attachment member and the top of the receiving body are fixed at the welded fixing portion, making the roof receiving device of the present invention an extremely strong structure.

さらに、受本体は、嵌合取付部材と受本体とを備えたものであり、嵌合取付部材は、ベース板状部と膨出部とを有している。ベース板状部は長方形状であり、そのＸ方向つまり長手方向の両端部分を嵌合端部としたものである。つまり、長方形状のベース板状部のＸ方向両端を嵌合端部としたことにより、折板屋根板の被嵌合屈曲部に嵌合する嵌合端部は直線状で嵌合範囲を大きく且つ有効的に確保することができる。 Furthermore, the receiving body is equipped with a fitting attachment member and the receiving body, and the fitting attachment member has a base plate portion and a bulge portion. The base plate portion is rectangular, and both ends in the X direction, i.e., in the longitudinal direction, are fitting ends. In other words, by making both ends in the X direction of the rectangular base plate portion into fitting ends, the fitting ends that fit into the fitted bent portion of the folded roof panel are linear, and a large and effective fitting range can be ensured.

膨出部は、ベース板状部をベースとして上方に向かって膨出する構造としたものであり、そのため膨出部は、略シェル的な構造或いは略モノコック的な構造となる。したがって、ベース板状部と膨出部とが相互に他方を補強することができ、嵌合取付部材は、力学的強度に優れたものにできる。 The bulging portion is structured to bulge upward from the base plate portion, and therefore has a roughly shell-like or monocoque structure. As a result, the base plate portion and the bulging portion can mutually reinforce each other, and the fitting attachment member can have excellent mechanical strength.

請求項１の発明では、前記嵌合取付部材の前記膨出部は、膨出段差立上り面部の一方側に前記吊子装着用孔を有する膨出低位頂部が形成され他方側に膨出高位頂部が形成され、前記受本体の前記受頂部は、受段差立上り面部の一方側に前記接合用孔及び前記内ネジ部材を有する受低位頂部が形成され他方側に受高位頂部が形成され、前記膨出低位頂部には前記受低位頂部が収容され、前記膨出高位頂部には前記受高位頂部が収容され、前記膨出低位頂部と前記受低位頂部と、前記膨出高位頂部と前記受高位頂部との少なくとも何れか一方の面同士が溶接固着された構成によって、馳締タイプの折板屋根の施工に好適な屋根用受具にできる。 In the invention of claim 1 , the bulging portion of the fitting mounting member has a bulging low-level top having a hole for attaching the retaining clip on one side of the bulging step rising surface portion and a bulging high-level top on the other side, and the receiving top portion of the receiving body has a low-level top having the joining hole and the internal screw member on one side of the receiving step rising surface portion and a high-level top on the other side, the bulging low-level top is accommodated in the bulging high-level top and the high-level top is accommodated in the bulging low-level top, and at least one of the surfaces of the bulging low-level top and the receiving low-level top, and the bulging high-level top and the receiving high-level top are welded and fixed to each other, making it possible to make a roof receiving device that is suitable for constructing a fastening type folded plate roof.

具体的に述べると、段差立上り面部の一方側に低位頂部が形成され他方側に高位頂部が形成された構造であり、特に馳締タイプの折板屋根板による折板タイプの屋根，壁面の施工に好適となる。つまり、膨出部に低位頂部及び高位頂部が設けられており、折板屋根板を装着するための吊子を前記低位頂部に設置することで、馳締タイプの折板屋根板同士の馳締連結部を安定した状態で配置することができる。 Specifically, this structure has a low peak on one side of the step rising surface and a high peak on the other side, making it particularly suitable for construction of folded-plate type roofs and walls using fastening type folded-plate roof panels. In other words, a low peak and a high peak are provided on the bulge, and by installing a retaining clip for attaching the folded-plate roof panel at the low peak, the fastening connection between fastening type folded-plate roof panels can be arranged in a stable state.

さらに、請求項１の発明では、前記溶接固着の位置は、前記膨出高位頂部と前記受高位頂部との接触面とした構成により、膨出高位頂部における溶接固着部と、膨出低位頂部の馳締吊子の装着における内ネジ部材とボルトによって、溶接固着部の領域と、内ネジ部材とボルトによる固着領域とが所定間隔をおいて離れた位置に存在することになり、両固着部によって一層強固な屋根用受具にすることができる。 Furthermore, in the invention of claim 1 , the position of the welded fastening is configured to be the contact surface between the bulging high top and the receiving high top, so that the welded fastening area at the bulging high top and the fastening area by the internal thread member and bolt are located at positions spaced a predetermined distance apart by the welded fastening area at the bulging high top and the internal thread member and bolt used to attach the fastening clip at the bulging low top, and the two fastening areas make it possible to make the roof receiving fixture even stronger.

請求項２の発明では、前記受頂部の平坦状面と、前記膨出部の下面との接触面同士の溶接はスポット溶接としたことにより、嵌合取付部材と受本体相互に溶接による熱歪の変形を最小限にすることができる。そして、このスポット溶接とし、前述した受頂部に形成された接合用孔と、受頂部下面側で且つ前記接合用孔箇所に溶接固着された内ネジ部材とにより、折板屋根の施工において、吊子等の屋根施工に必要な部品が前記内ネジ部材を介してボルト締めされる構成とが相乗的に作用することで、強固な屋根用受具にすることができる。 In the invention of claim 2 , the welding of the contact surfaces between the flat surface of the receiving top and the underside of the bulging portion is performed by spot welding, thereby minimizing the thermal distortion caused by welding between the fitting mounting member and the receiving body. This spot welding, the joint hole formed in the receiving top, and the internal thread member welded and fixed to the underside of the receiving top and to the joint hole location work synergistically with the configuration in which parts necessary for roof construction such as retaining clips are bolted via the internal thread member during the construction of the folded plate roof, making it possible to make a strong roof receiving device.

請求項３の発明では、極めて強固な屋根用受具を使用した折板屋根としたことにより、折板屋根板によって施工された屋根を極めて強固に支持固定し、特に台風による強風の負圧に対しても、折板屋根板が吹き飛ばされないように支持し、耐久性の優れた折板屋根とすることができる。請求項４の発明では、極めて強固な馳締タイプの折板屋根を施工できる。
In the invention of claim 3 , by using an extremely strong roof support, the roof constructed with the folded plate roof panels can be supported and fixed extremely strongly, and the folded plate roof panels can be supported so as not to be blown away even by the negative pressure of strong winds caused by typhoons, making it possible to make a folded plate roof with excellent durability. In the invention of claim 4 , an extremely strong fastening type folded plate roof can be constructed.

以下、本発明の実施形態について図面に基づいて説明する。本発明は、折板屋根を構成する屋根用受具Ａと、該屋根用受具Ａによって施工される折板屋根である。また、本発明において折板屋根を構成する折板屋根板によって急傾斜で略壁面状に施工されたものについても本発明における屋根に含まれるものとする。 The following describes an embodiment of the present invention based on the drawings. The present invention relates to a roof support A that constitutes a folded-plate roof, and a folded-plate roof that is constructed using the roof support A. In addition, the present invention also includes roofs that are constructed in a steeply inclined, approximately wall-like shape using the folded-plate roof panels that constitute the folded-plate roof.

まず、本発明では、方向を示す文言としてＸ方向及びＹ方向を使用する。本発明の屋根用受具Ａによって、施工される複数の折板屋根板８，８，…が並列される方向をＸ方向とし〔図４（Ｂ）参照〕、各折板屋根板８の長手方向となる方向をＹ方向とする。したがって、本発明の屋根用受具Ａが装着される構造材９の長手方向はＸ方向となる（図４参照）。Ｙ方向及びＸ方向については、図中に記載した。 First, in this invention, the terms X-direction and Y-direction are used to indicate directions. The direction in which the multiple folded roof panels 8, 8, ... installed by the roof support A of the present invention are arranged side by side is the X-direction (see Figure 4 (B)), and the direction that is the longitudinal direction of each folded roof panel 8 is the Y-direction. Therefore, the longitudinal direction of the structural material 9 to which the roof support A of the present invention is attached is the X-direction (see Figure 4). The Y-direction and X-direction are indicated in the figure.

本発明ににおける屋根用受具Ａには、第１実施形態及び第２実施形態が存在し、何れも金属製の嵌合取付部材Ａ1と、金属製の受本体Ａ2とによって構成される。嵌合取付部材Ａ1は、ベース板状部１と膨出部２とから構成される（図１参照）。ベース板状部１は、Ｘ方向を長手方向とした長方形の板状に形成されたものである。ベース板状部１の板厚寸法は、約２mm至約２.５mm程度が好適である。 There are a first and a second embodiment of the roof support A in this invention, both of which are composed of a metal fitting attachment member A1 and a metal support body A2. The fitting attachment member A1 is composed of a base plate portion 1 and a bulge portion 2 (see Figure 1). The base plate portion 1 is formed in a rectangular plate shape with the X direction as the longitudinal direction. The plate thickness dimension of the base plate portion 1 is preferably about 2 mm to about 2.5 mm.

本発明における屋根用受具Ａの第１実施形態では、膨出部２は、下方に開口２ｋを有しており、前記ベース板状部１の上方から見ると凸状の膨らみ状で且つ下方から見ると凹状の窪みとなる部位であり、ベース板状部１を土台として、四方及び上方が全て閉鎖状となった構造である（図１，図２参照）。具体的には、カプセルを半割にした略方形状容器のような形状である。膨出部２は、上面から見ると略長方形状であり、その４つの角部は丸み、つまり円弧状に形成されている〔図３(Ｂ)，（Ｅ）参照〕。 In the first embodiment of the roof support A of the present invention, the bulge 2 has an opening 2k on the bottom, and is a part that is a convex bulge when viewed from above the base plate part 1 and a concave recess when viewed from below, and has a structure in which all four sides and the top are closed with the base plate part 1 as the base (see Figures 1 and 2). Specifically, it is shaped like a roughly square container made by splitting a capsule in half. The bulge 2 is roughly rectangular when viewed from above, and its four corners are rounded, that is, formed in an arc shape (see Figures 3(B) and (E)).

また、膨出部２は、ベース板状部１に対して、その内部に収まるようにして、最大限の面積を有するように形成されている〔図３(Ｂ)，（Ｅ）参照〕。つまり、膨出部２の平面形状は、ベース板状部１の平面形状の範囲内において占める割合が大きい。膨出部２の４個の角は円弧状であり、そのためにベース板状部１の４個の隅は、平坦状の部位として残されている。さらに、ベース板状部１の長辺付近は僅かに略平坦となる部位が残されている〔図１（Ｃ），図２（Ａ），図３（Ｂ），（Ｅ）等参照〕。 The bulge 2 is formed to have the maximum area possible so that it fits inside the base plate 1 (see Figures 3(B) and (E)). In other words, the planar shape of the bulge 2 occupies a large proportion of the planar shape of the base plate 1. The four corners of the bulge 2 are arc-shaped, so the four corners of the base plate 1 remain flat. Furthermore, there are small areas that are approximately flat near the long sides of the base plate 1 (see Figures 1(C), 2(A), 3(B), (E), etc.).

膨出部２には、Ｘ方向の中間箇所に膨出段差立上り面部２１が設けられている〔図１（Ｂ），（Ｃ），図２，図３等参照〕。該膨出段差立上り面部２１は、膨出部２のＸ方向或いは長手方向に直交且つ略垂直状の面である。該膨出段差立上り面部２１を境にしてＸ方向における一方側の部分を膨出低位頂部２２であり、Ｘ方向における他方側の部分を膨出高位頂部２３である。膨出低位頂部２２は、膨出高位頂部２３よりも低い位置となっている〔図１（Ｂ），（Ｃ），図２，図３等参照〕。膨出低位頂部２２には、後述する馳締吊子８４が装着される部位となる（図４参照）。 The bulging portion 2 has a bulging step rising surface 21 at the middle in the X direction (see Figs. 1B, 1C, 2, 3, etc.). The bulging step rising surface 21 is a surface that is perpendicular to the X direction or the longitudinal direction of the bulging portion 2 and is substantially vertical. The portion on one side in the X direction of the bulging step rising surface 21 is the bulging low-level apex 22, and the portion on the other side in the X direction is the bulging high-level apex 23. The bulging low-level apex 22 is located lower than the bulging high-level apex 23 (see Figs. 1B, 1C, 2, 3, etc.). The bulging low-level apex 22 is the portion to which the swivel clamp 84, described later, is attached (see Fig. 4).

膨出部２のＸ方向（長手方向）の両側面、つまり、膨出低位頂部２２及び膨出高位頂部２３の外方に面する側面は、上方から下方に向かって外方に傾斜する傾斜状の面として形成されている。そして、膨出低位頂部２２側に連続する傾斜面を低位傾斜面２４と称し、膨出高位頂部２３側に連続する傾斜面を高位傾斜面２５と称する〔図１(Ｂ)，図２（Ｂ），図３（Ａ），（Ｄ）参照〕。前記膨出低位頂部２２と低位傾斜面２４との角部２２ｔは、円弧状の丸みを有している。同様に、膨出高位頂部２３と高位傾斜面２５との角部２３ｔも円弧状の丸みを有している〔図１(Ｂ)，図２（Ｂ），図３（Ａ），（Ｄ）参照〕。 The two side surfaces of the bulging portion 2 in the X direction (longitudinal direction), that is, the outward facing side surfaces of the bulging low-level apex 22 and the bulging high-level apex 23, are formed as inclined surfaces that incline outward from above to below. The inclined surface continuing to the bulging low-level apex 22 side is called the low-level inclined surface 24, and the inclined surface continuing to the bulging high-level apex 23 side is called the high-level inclined surface 25 (see Figures 1(B), 2(B), 3(A), and (D)). The corner 22t between the bulging low-level apex 22 and the low-level inclined surface 24 has an arc-shaped roundness. Similarly, the corner 23t between the bulging high-level apex 23 and the high-level inclined surface 25 also has an arc-shaped roundness (see Figures 1(B), 2(B), 3(A), and (D)).

前記ベース板状部１の長手方向つまりＸ方向の両端の位置は、嵌合端部１１，１１となっている〔図１(Ｂ)，図２（Ｂ），図３（Ａ），（Ｄ）参照〕。両該嵌合端部１１，１１は、長方形状の前記ベース板状部１の対向する両短辺部分で、直線の縁となっている。両該嵌合端部１１，１１は、後述する折板屋根板８の被嵌合屈曲部８２ａ，８２ａに嵌合して、折板屋根板８を屋根用受具に固定する役目をなす（図４参照）。つまり、ベース板状部１の嵌合端部１１は、その全体が折板屋根板８の被嵌合屈曲部８２ａに当接することができる〔図４（Ｃ）参照〕。また、嵌合端部１１は、前記膨出部２の低位傾斜面２４及び高位傾斜面２５の下端と同一位置となっている。 The positions of both ends of the longitudinal direction, i.e., the X-direction, of the base plate-shaped portion 1 are fitting ends 11, 11 [see Figs. 1(B), 2(B), 3(A), and (D)]. The fitting ends 11, 11 are straight edges on both opposing short sides of the rectangular base plate-shaped portion 1. The fitting ends 11, 11 fit into the fitting bent portions 82a, 82a of the folded roof panel 8 described later, and serve to fix the folded roof panel 8 to the roof support (see Fig. 4). In other words, the fitting end 11 of the base plate-shaped portion 1 can abut the fitting bent portion 82a of the folded roof panel 8 in its entirety [see Fig. 4(C)]. In addition, the fitting end 11 is located at the same position as the lower ends of the lower inclined surface 24 and the higher inclined surface 25 of the bulging portion 2.

両前記嵌合端部１１，１１には、ベース板状部１の下面側に向かって折り返し状の屈曲片１１ａが形成されている〔図１(Ｂ)，図２（Ｂ），図３（Ａ），（Ｄ）参照〕。両屈曲片１１ａは、共に略逆「ハ」字形状、又は水平状となるように屈曲形成される。両該屈曲片１１ａがベース板状部１の両嵌合端部１１，１１に形成されることにより、両嵌合端部１１，１１部分の力学的強度を向上させると共に、折板屋根板８の被嵌合屈曲部８２ａとの当接状態をより確実なものにできる。 At both of the fitting ends 11, 11, a bent piece 11a is formed that is folded back toward the underside of the base plate-like portion 1 [see Figures 1(B), 2(B), 3(A) and (D)]. Both of the bent pieces 11a are bent so that they are roughly inverted "U" shape or horizontal. By forming both of the bent pieces 11a at both of the fitting ends 11, 11 of the base plate-like portion 1, the mechanical strength of both of the fitting ends 11, 11 can be improved and the abutment state with the fitted bent portion 82a of the folded roof panel 8 can be made more reliable.

さらに、折板屋根板８の被嵌合屈曲部８２ａを、嵌合取付部材Ａ1の嵌合端部１１と嵌合させるときに、折板屋根板８の内面側に傷が付くことを防止することができる。前記膨出部２の膨出低位頂部２２には吊子装着用孔２８が形成されている。該吊子装着用孔２８は、後述する馳締吊子８４又は嵌合吊子８５を嵌合取付部材Ａ1上に固着するための連結用ボルト６１が貫通する孔である。 Furthermore, when the fitted bent portion 82a of the folded roof panel 8 is fitted with the fitting end portion 11 of the fitting mounting member A1, it is possible to prevent damage to the inner surface side of the folded roof panel 8. A retaining clip attachment hole 28 is formed in the bulging lower top portion 22 of the bulging portion 2. The retaining clip attachment hole 28 is a hole through which a connecting bolt 61 passes to fix the tightening retaining clip 84 or the fitting retaining clip 85 described later onto the fitting mounting member A1.

屋根用受具Ａの第１実施形態の変形例では、特に図示しないが、嵌合取付部材Ａ1の前記ベース板状部１に対して膨出部２が占有する面積を少なくしたものである。この変形例では、ベース板状部１の平坦状部が多く現われる。つまり、ベース板状部１には、膨出部２が形成されていない部位が第１実施形態の場合よりも広く存在することになり、ベース板状部１のＸ方向の両側部分のみならず、Ｙ方向の両側部分にも平坦状の部位が存在することになる。 In a modified version of the first embodiment of the roof support A, although not shown, the area occupied by the bulge 2 relative to the base plate portion 1 of the fitting attachment member A1 is reduced. In this modified version, the flat portions of the base plate portion 1 are more prominent. In other words, the base plate portion 1 has a larger area where the bulge 2 is not formed than in the first embodiment, and flat portions exist not only on both sides of the base plate portion 1 in the X direction, but also on both sides in the Y direction.

また、屋根用受具Ａの第１実施形態の第２変形例として、特に図示しないが、嵌合取付部材Ａ1の膨出部２の低位傾斜面２４及び高位傾斜面２５を、略垂直状にすることもある。これによって、嵌合取付部材Ａ1は、膨出部２の成形範囲をより一層狭くし、ベース板状部１の平坦状部分を大きくすることができる。第１実施形態のこれらの変形例のように、ベース板状部１に対して膨出部２の形成領域を小さくすることにより、ベース板状部１の嵌合端部１１，１１の形状がより一層、突出し且つ嵌合端部１１における屈曲片１１ａ部分の角度がより一層鋭角となり、折板屋根板の被嵌合屈曲部８２ａに食い込み易くすることができ、折板屋根板８の屋根用受具に対する固定状態をより一層強固なるものにすることができる。 In addition, as a second modification of the first embodiment of the roof support A, although not shown, the lower inclined surface 24 and the higher inclined surface 25 of the bulge portion 2 of the fitting mounting member A1 may be made substantially vertical. This allows the fitting mounting member A1 to further narrow the molding range of the bulge portion 2 and to enlarge the flat portion of the base plate portion 1. As in these modifications of the first embodiment, by reducing the forming area of the bulge portion 2 relative to the base plate portion 1, the shape of the fitting end portions 11, 11 of the base plate portion 1 protrudes further and the angle of the bent piece 11a portion at the fitting end portion 11 becomes even more acute, making it easier to bite into the fitted bent portion 82a of the folded roof panel, and making the fixed state of the folded roof panel 8 to the roof support even stronger.

第１実施形態及び第１実施形態の変形例の嵌合取付部材Ａ1は、前述したように、ベース板状部１に膨出部２が膨出形成されることにより、膨出部２はカプセルを半割にした容器のような形状となる。したがって、膨出部２は、略シェル的な構造或いは略モノコック的な構造となり、ベース板状部１と膨出部２とが相互に他方を補強することができ、嵌合取付部材Ａ1は、相乗的に力学的強度に優れたものにできる。 As described above, in the fitting attachment member A1 of the first embodiment and the modified example of the first embodiment, the bulge portion 2 is formed by bulging out from the base plate portion 1, so that the bulge portion 2 has a shape similar to a container formed by splitting a capsule in half. Therefore, the bulge portion 2 has a roughly shell-like structure or a roughly monocoque structure, and the base plate portion 1 and the bulge portion 2 can mutually reinforce each other, so that the fitting attachment member A1 can be synergistically made to have excellent mechanical strength.

次に、第１実施形態における受本体Ａ2は、受頂部５１と脚部５２，５２とから構成されている〔図１，図２（Ａ），（Ｂ），図３，図４等参照〕。前記受頂部５１は、受段差立上り面部５１０と受低位頂部５１１と受高位頂部５１２とを有している〔図１，図２（Ａ），（Ｂ），図３，図４等参照〕。そして、受段差立上り面部５１０は、受頂部５１において、略垂直状の段差境界部である。受段差立上り面部５１０を境として、受頂部５１の幅方向（Ｘ方向）の一方側に受低位頂部５１１が形成され、他方側に受高位頂部５１２が形成されている〔図２（Ａ），（Ｂ）参照〕。 Next, the receiving body A2 in the first embodiment is composed of a receiving top 51 and legs 52, 52 (see Fig. 1, Fig. 2 (A), (B), Fig. 3, Fig. 4, etc.). The receiving top 51 has a receiving step rising surface 510, a receiving low-level top 511, and a receiving high-level top 512 (see Fig. 1, Fig. 2 (A), (B), Fig. 3, Fig. 4, etc.). The receiving step rising surface 510 is a substantially vertical step boundary portion in the receiving top 51. With the receiving step rising surface 510 as a boundary, the receiving low-level top 511 is formed on one side of the receiving top 51 in the width direction (X direction) and the receiving high-level top 512 is formed on the other side (see Fig. 2 (A) and (B)).

該接合用孔５１３の箇所で、受低位頂部５１１の下面側には、内ネジ部材６２が溶接手段によって固着されている〔図１（Ｂ），図２（Ｂ），図３（Ａ），（Ｄ）等参照〕。該内ネジ部材６２は、貫通孔の内周に内ネジ６２ａが形成された部材であって、具体的にはナットが使用されることが好適である。また、内ネジ部材６２は、特に図示しないが、直方体又は扁平直方体等の金属材に内ネジ６２ａが形成された部材であっても構わない。 At the location of the connection hole 513, an internally threaded member 62 is fixed by welding to the underside of the receiving lower top 511 (see Figs. 1(B), 2(B), 3(A), (D), etc.). The internally threaded member 62 is a member in which an internal thread 62a is formed on the inner circumference of a through hole, and specifically, a nut is preferably used. Although not shown, the internally threaded member 62 may also be a member in which an internal thread 62a is formed in a metal material such as a rectangular parallelepiped or flattened rectangular parallelepiped.

前記脚部５２，５２は、前記受頂部５１の幅方向（Ｘ方向）両端から外方下向きに傾斜するようにして形成されたものである。そして、嵌合取付部材Ａ1の膨出低位頂部２２は、受本体Ａ2の受低位頂部５１１と対応し、嵌合取付部材Ａ1の膨出高位頂部２３は受本体Ａ2の受高位頂部５１２と対応するようにして、嵌合取付部材Ａ1が受本体Ａ2上に配置される〔図１，図２，図３（Ａ），（Ｄ），図４等参照〕。 The legs 52, 52 are formed so as to slope outward and downward from both ends of the receiving top 51 in the width direction (X direction). The fitting mounting member A1 is placed on the receiving body A2 so that the bulging low top 22 of the fitting mounting member A1 corresponds to the receiving low top 511 of the receiving body A2, and the bulging high top 23 of the fitting mounting member A1 corresponds to the receiving high top 512 of the receiving body A2 (see Figures 1, 2, 3(A), (D), 4, etc.).

受頂部５１は、膨出部２内に収容可能とされ、受頂部５１の平坦状面と膨出部２の下面との接触面同士が溶接される（図３参照）。さらに詳細には、膨出部２の下方の開口２ｋ側から受本体Ａ2の受頂部５１が挿入される〔図２（Ｂ）参照〕。嵌合取付部材Ａ1の膨出部２の、膨出低位頂部２２に受本体Ａ2の受低位頂部５１１が収容され、膨出高位頂部２３には受高位頂部５１２が収容される〔図３（Ｃ）参照〕。そして、膨出低位頂部２２と受低位頂部５１１と、膨出高位頂部２３と受高位頂部５１２との少なくとも何れか一方の面同士が溶接固着される〔図１（Ｂ），（Ｃ），図３，図４（Ａ），（Ｃ）等参照〕。この溶接固着された溶接部位を溶接固着部Ａｗと称する。 The receiving top 51 can be accommodated in the bulging portion 2, and the contact surfaces of the flat surface of the receiving top 51 and the lower surface of the bulging portion 2 are welded together (see FIG. 3). More specifically, the receiving top 51 of the receiving body A2 is inserted from the opening 2k side below the bulging portion 2 (see FIG. 2(B)). The receiving low top 511 of the receiving body A2 is accommodated in the bulging low top 22 of the bulging portion 2 of the fitting mounting member A1, and the receiving high top 512 is accommodated in the bulging high top 23 (see FIG. 3(C)). At least one of the surfaces of the bulging low top 22 and the receiving low top 511, and the bulging high top 23 and the receiving high top 512 are welded together (see FIG. 1(B), (C), FIG. 3, FIG. 4(A), (C), etc.). This welded and secured portion is called the welded portion Aw.

溶接固着部Ａｗの具体的な位置は、嵌合取付部材Ａ1の膨出高位頂部２３と、受本体Ａ2の受高位頂部５１２との接触面同士となる部位が好適である〔図１（Ｂ），（Ｃ），図３（Ａ），（Ｂ），（Ｃ）等参照〕。該溶接固着部Ａｗは、嵌合取付部材Ａ1と受本体Ａ2の共に平坦な接触面同士の適宜の位置に設けられるものである。本発明において、嵌合取付部材Ａ1と受本体Ａ2との溶接が行われる溶接固着部Ａｗは、スポット溶接が好適である。 The specific location of the welded and fixed portion Aw is preferably the portion where the contact surfaces of the bulging high top 23 of the fitting attachment member A1 and the receiving high top 512 of the receiving body A2 meet (see Figs. 1(B), (C), 3(A), (B), (C), etc.). The welded and fixed portion Aw is provided at an appropriate position on the flat contact surfaces of both the fitting attachment member A1 and the receiving body A2. In the present invention, the welded and fixed portion Aw where the welding between the fitting attachment member A1 and the receiving body A2 is performed is preferably spot welding.

具体的には、膨出高位頂部２３と、受高位頂部５１２との接触面同士が前後方向（Ｙ方向）において２箇所設けられる〔図１（Ｃ），図３（Ｂ），（Ｃ）参照〕。また、前後方向の２点を結ぶようにして、シーム溶接とすることもある。前記溶接固着部Ａｗをスポット溶接又はシーム溶接とすることにより、製造時における溶接による嵌合取付部材Ａ1及び受本体Ａ2の熱変形を略防止できる。 Specifically, the contact surfaces between the bulging high apex 23 and the receiving high apex 512 are provided at two points in the front-to-rear direction (Y direction) [see Fig. 1 (C), Fig. 3 (B), (C)]. In addition, seam welding may be used to connect the two points in the front-to-rear direction. By spot welding or seam welding the welded fixing portion Aw, thermal deformation of the fitting attachment member A1 and receiving body A2 due to welding during manufacturing can be substantially prevented.

スポット溶接又はシーム溶接とした溶接固着部Ａｗは、嵌合取付部材Ａ1の膨出高位頂部２３と、受本体Ａ2の受高位頂部５１２との接触面同士に設けられることが好適である。嵌合取付部材Ａ1の膨出低位頂部２２と、受本体Ａ2の受低位頂部５１１とは、吊子設置面箇所及び支持箇所となり、膨出高位頂部２３と受高位頂部５１２とがスポット溶接又はシーム溶接による溶接固着部Ａｗが設けられ、且つ馳締吊子８４，膨出低位頂部２２及び受低位頂部５１１とが連結用ボルト６１及び内ネジ部材６２で固着されることで、溶接固着部Ａｗと連通、相互の固着力により、嵌合取付部材Ａ1と受本体Ａ2とが強固に接合され、極めて強固な屋根用受具にすることができる。 The spot-welded or seam-welded welded fastening portion Aw is preferably provided on the contact surfaces of the bulging high top 23 of the fitting attachment member A1 and the receiving high top 512 of the receiving body A2. The bulging low top 22 of the fitting attachment member A1 and the receiving low top 511 of the receiving body A2 become the retaining clip installation surface and support portion, and the bulging high top 23 and the receiving high top 512 are provided with a spot-welded or seam-welded welded fastening portion Aw, and the fastening clip 84, the bulging low top 22, and the receiving low top 511 are fastened with the connecting bolt 61 and the internal thread member 62, so that the welded fastening portion Aw is connected, and the fitting attachment member A1 and the receiving body A2 are firmly joined by the mutual fastening force, making it possible to make an extremely strong roof support.

また、スポット溶接又はシーム溶接とした溶接固着部Ａｗが、嵌合取付部材Ａ1の膨出低位頂部２２と受低位頂部５１１との接触面同士に設けられることもある〔図３（Ｄ），（Ｅ）参照〕。この場合、スポット溶接又はシーム溶接の位置は、嵌合取付部材Ａ1の膨出段差立上り面部２１の直近であることが好適である。 In addition, a spot weld or seam welded welded attachment portion Aw may be provided on the contact surfaces of the bulging lower top portion 22 and the receiving lower top portion 511 of the fitting attachment member A1 (see Figures 3 (D) and (E)). In this case, it is preferable that the spot weld or seam weld is located immediately adjacent to the bulging step rising surface portion 21 of the fitting attachment member A1.

第１実施形態における屋根用受具Ａに対応する折板屋根板８は、馳締タイプの折板屋根Ｂ1を１施工するものである。該折板屋根板８は、主板８１の幅方向（Ｘ方向）両側に傾斜状の立上り部８２，８２が形成され、該立上り部８２，８２の上端に連結頂部８３，８３が形成されている。 The folded roof panel 8 corresponding to the roof support A in the first embodiment is used to install a fastening type folded roof B1. The folded roof panel 8 has inclined rising parts 82, 82 formed on both sides of the width direction (X direction) of the main panel 81, and connecting tops 83, 83 formed at the upper ends of the rising parts 82, 82.

折板屋根板８の幅方向一方側の連結頂部８３には、下馳部８３ａが形成され、他方側の連結頂部８３には上馳部８３ｂが形成されている。下馳部８３ａ及び上馳部８３ｂは、その断面形状に円弧形状の部分が存在する丸馳形状に形成されたものである（図４参照）。その他に特に図示しないが、形状を略方形状とした角馳タイプのものや、形状を略逆Ｌ字形状とした立馳タイプのものが存在する。 A lower run portion 83a is formed on the connecting apex 83 on one side of the width direction of the folded roof panel 8, and an upper run portion 83b is formed on the connecting apex 83 on the other side. The lower run portion 83a and the upper run portion 83b are formed in a round run shape with an arc-shaped portion in their cross-sectional shape (see Figure 4). In addition, although not specifically shown, there are also angular run types that are roughly square in shape and vertical run types that are roughly inverted L-shaped.

次に、両前記立上り部８２には、被嵌合屈曲部８２ａがそれぞれ形成されている。該被嵌合屈曲部８２ａは、両前記立上り部８２の高さ方向の中間箇所に段状部として形成されたものであり、該立上り部８２において、前記段状部の上方側が下方側よりも外方に突出するように形成された部位である〔図４（Ｂ），（Ｃ）参照〕。 Next, a fitted bent portion 82a is formed on each of the rising portions 82. The fitted bent portion 82a is formed as a step portion at the midpoint of the height of each of the rising portions 82, and is a portion of the rising portion 82 formed so that the upper side of the step portion protrudes outward more than the lower side (see Figures 4(B) and (C)).

該被嵌合屈曲部８２ａは、前記嵌合取付部材Ａ1の嵌合端部１１と嵌合し、隣接する折板屋根板８，８同士の下馳部８３ａと上馳部８３ｂとによる馳締箇所と共に折板屋根板８を、本発明における屋根用受具Ａによって梁，母屋，胴縁等の構造材９上に固定する役目をなすものである（図４参照）。 The bent portion 82a engages with the engaging end 11 of the engaging mounting member A1, and together with the fastening points between the lower running portion 83a and the upper running portion 83b of adjacent folded roof panels 8, 8, serves to fix the folded roof panel 8 to the structural material 9 such as a beam, purlin, or furring strip by the roof support A of the present invention (see Figure 4).

次に、本発明の屋根用受具Ａと折板屋根板８と構造材９にて馳締タイプの折板屋根Ｂ1を施工する工程について説明する。まず、複数の本発明の屋根用受具Ａ，Ａ，…が、母屋等の構造材９上に配置される。このとき、それぞれの隣接する屋根用受具の間隔は、折板屋根板８の幅方向両側に形成された被嵌合屈曲部８２ａ，８２ａに対して、隣接する嵌合取付部材Ａ1，Ａ1のそれぞれの嵌合端部１１，１１が適正に嵌合することができる範囲に設定される〔図４（Ａ）参照〕。 Next, the process of constructing a fastening type folded plate roof B1 using the roof support A of the present invention, a folded plate roof panel 8, and a structural material 9 will be described. First, multiple roof supports A, A, ... of the present invention are placed on a structural material 9 such as a purlin. At this time, the spacing between adjacent roof supports is set to a range in which the fitting ends 11, 11 of the adjacent fitting mounting members A1, A1 can be properly fitted into the fitting bent portions 82a, 82a formed on both sides of the width of the folded plate roof panel 8 [see Figure 4 (A)].

そして、隣接する屋根用受具Ａ，Ａの対向する嵌合取付部材Ａ1，Ａ1間に折板屋根板８が配置され、該折板屋根板８を押し込むようにして、その両被嵌合屈曲部８２ａ，８２ａと、隣接する屋根用受具の嵌合取付部材Ａ1，Ａ1の嵌合突出部１１，１１とを嵌合させる〔図４（Ｃ）参照〕。また、屋根用受具の嵌合取付部材Ａ1の膨出低位頂部２２に、馳締吊子８４を連結具６の連結用ボルト６１と内ネジ部材６２によって固着し、隣接する折板屋根板８，８同士の下馳部８３ａと上馳部８３ｂとを馳締して屋根を施工するものである（図４参照）。 Then, the folded roof panel 8 is placed between the opposing fitting attachment members A1, A1 of the adjacent roof support A, and the folded roof panel 8 is pushed in so that its fitted bent portions 82a, 82a fit into the fitting protrusions 11, 11 of the fitting attachment members A1, A1 of the adjacent roof support (see Figure 4 (C)). The fastening bar 84 is fixed to the bulging lower top 22 of the fitting attachment member A1 of the roof support by the connecting bolt 61 and the internal thread member 62 of the connector 6, and the lower running portion 83a and the upper running portion 83b of the adjacent folded roof panels 8, 8 are fastened to each other to construct the roof (see Figure 4).

前記馳締吊子８４は、座金部８４ａと舌片８４ｂとを備えており、前記座金部８４ａが嵌合取付部材Ａ1の膨出低位頂部２２上に載置され、前記連結具６の連結用ボルト６１と内ネジ部材６２によって座金部８４ａが固着されるものである。該座金部８４ａには、連結用ボルト６１が貫通する貫通孔が形成されている。また、隣接する折板屋根板８，８の下馳部８３ａと上馳部８３ｂとは、馳締吊子８４の舌片８４ｂを挟むようにして馳締される〔図４（Ｂ），（Ｃ）参照〕。 The fastening rod 84 has a washer portion 84a and a tongue piece 84b. The washer portion 84a is placed on the bulging lower top portion 22 of the fitting mounting member A1, and the washer portion 84a is fixed by the connecting bolt 61 and the internal thread member 62 of the connector 6. A through hole is formed in the washer portion 84a through which the connecting bolt 61 passes. In addition, the lower running portion 83a and the upper running portion 83b of the adjacent folded roof panels 8, 8 are fastened by sandwiching the tongue piece 84b of the fastening rod 84 [see Figures 4 (B) and (C)].

このように、折板屋根板８は、馳締吊子８４を介して、本発明の屋根用受具Ａの嵌合取付部材Ａ1の膨出低位頂部２２に固定支持されると共に、屋根用受具Ａの両嵌合端部１１，１１によって、折板屋根板８の被嵌合屈曲部８２ａ，８２ａが嵌合部固定されるものである。 In this way, the folded roof panel 8 is fixed and supported to the bulging lower top 22 of the fitting mounting member A1 of the roof support A of the present invention via the clamping clip 84, and the fitted bent portions 82a, 82a of the folded roof panel 8 are fixed to the fitting portions by both fitting ends 11, 11 of the roof support A.

つまり、本発明の屋根用受具Ａは、折板屋根板８を嵌合取付部材Ａ1の膨出低位頂部２２に装着された馳締吊子８４及び嵌合端部１１，１１の複数個所で固定することができるものである。これによって、本発明の屋根用受具Ａは、折板屋根板８，８，…によって施工された屋根を極めて強固に支持固定し、特に強風による負圧に対して優れた耐久性を発揮できるものである。 In other words, the roof support A of the present invention can fix the folded roof panel 8 at multiple points, including the fastening clip 84 attached to the bulging lower top 22 of the fitting mounting member A1 and the fitting ends 11, 11. As a result, the roof support A of the present invention can very firmly support and fix the roof constructed with the folded roof panels 8, 8, ... and can demonstrate excellent durability, especially against negative pressure caused by strong winds.

次に、本発明における屋根用受具Ａの第２実施形態について、主に図５及び図６に基づいて説明する。屋根用受具Ａの第２実施形態では、嵌合キャップ材８６及び嵌合吊子８５を使用した嵌合タイプの折板屋根に対応するものである（図５，図６参照）。第２実施形態における嵌合取付部材Ａ1は、第１実施形態における嵌合取付部材Ａ1と略同等の構成であり、ベース板状部１と膨出部２とから構成される。ベース板状部１は、Ｘ方向を長手方向とした長方形の板状に形成されたものである。ベース板状部１の板厚寸法は、約２mm乃至約２.５mm程度が好適である。 Next, a second embodiment of the roof support A of the present invention will be described mainly with reference to Figures 5 and 6. The second embodiment of the roof support A corresponds to an interlocking type folded plate roof using an interlocking cap material 86 and an interlocking retaining clip 85 (see Figures 5 and 6). The interlocking mounting member A1 in the second embodiment has a configuration substantially the same as that of the interlocking mounting member A1 in the first embodiment, and is composed of a base plate portion 1 and a bulge portion 2. The base plate portion 1 is formed in a rectangular plate shape with the X direction as the longitudinal direction. The plate thickness dimension of the base plate portion 1 is preferably about 2 mm to about 2.5 mm.

膨出部２は、前記ベース板状部１の上方から見ると略台形状とした凸状の膨らみ部分で、且つ下方から見ると凹状の窪みとなる部位であり、ベース板状部１を土台として、四方及び上方が全て閉鎖状となった構造である〔図５（Ａ），（Ｂ）参照〕。そして膨出部２の下方側には開口２ｋが存在する。具体的には、カプセルを半割にした略方形状容器のような形状である。膨出部２は、上面から見ると略長方形状であり、その４つの角部は丸み、つまり円弧状に形成されている〔図５（Ｃ）参照〕。 The bulge 2 is a convex bulge that is approximately trapezoidal when viewed from above the base plate 1, and a concave recess when viewed from below, with the base plate 1 as the base and a structure in which all four sides and the top are closed (see Figures 5(A) and (B)). An opening 2k exists on the lower side of the bulge 2. Specifically, it is shaped like a roughly square container made by splitting a capsule in half. The bulge 2 is approximately rectangular when viewed from above, and its four corners are rounded, that is, formed in an arc shape (see Figure 5(C)).

また、膨出部２は、ベース板状部１に対して、その内部に収まるようにして、最大限の面積を有するように形成されている〔図５（Ｂ），図６（Ａ），（Ｃ）参照〕。つまり、膨出部２の平面形状は、ベース板状部１の平面形状の範囲内において占める割合が大きい。膨出部２の４個の角は円弧状であり、そのためにベース板状部１の４個の隅は、平坦状の部位として残されている。さらに、ベース板状部１の長辺付近は僅かに略平坦となる部位が残されている。 The bulge 2 is formed to have the maximum area possible so that it fits inside the base plate portion 1 (see Figs. 5(B), 6(A) and (C)). In other words, the planar shape of the bulge 2 occupies a large proportion of the planar shape of the base plate portion 1. The four corners of the bulge 2 are arc-shaped, so the four corners of the base plate portion 1 remain as flat areas. Furthermore, a small area that is approximately flat remains near the long sides of the base plate portion 1.

膨出部２は、平坦状の略単一面とした平坦状頂部２６を有し、Ｘ方向の両端には傾斜状の端面２７，２７が形成されている。前記平坦状頂部２６と傾斜状の両前記端面２７，２７との角部２６ｔ，２６ｔは、円弧状の丸みを有している〔図５（Ｂ），（Ｃ），図６（Ａ），（Ｃ）参照〕。 The bulge 2 has a flat top 26 that is a flat, substantially single surface, and has inclined end faces 27, 27 at both ends in the X direction. The corners 26t, 26t between the flat top 26 and the inclined end faces 27, 27 are rounded in an arc shape (see Figures 5(B), (C), 6(A), (C)).

前記ベース板状部１は、第１実施形態における嵌合取付部材Ａ1のベース板状部１と同等であり、長手方向つまりＸ方向の両端の位置は、嵌合端部１１，１１となっている。両前記嵌合端部１１，１１には、ベース板状部１の下面側に向かって折り返し状の屈曲片１１ａ，１１ａが形成されている。前記膨出部２の平坦状頂部２６には吊子装着用孔２８が形成されている〔図５，図６（Ａ）参照〕。該吊子装着用孔２８は、嵌合吊子８５を嵌合取付部材Ａ1上に固着するための連結用ボルト６１が貫通する孔である。 The base plate portion 1 is the same as the base plate portion 1 of the fitting attachment member A1 in the first embodiment, and the positions of both ends in the longitudinal direction, i.e., the X direction, are fitting ends 11, 11. The fitting ends 11, 11 are formed with bent pieces 11a, 11a that are folded back toward the underside of the base plate portion 1. A retaining clip attachment hole 28 is formed in the flat top 26 of the bulge portion 2 [see Figures 5 and 6 (A)]. The retaining clip attachment hole 28 is a hole through which a connecting bolt 61 passes to secure the fitting retaining clip 85 to the fitting attachment member A1.

次に、本発明における屋根用受具Ａの第２実施形態の受本体Ａ2は、平坦状受頂部５３と脚部５２，５２とから構成されている〔図５，図６（Ａ）参照〕。前記平坦状受頂部５３は、平坦状に形成されている。そして、該平坦状受頂部５３には、幅方向（Ｘ方向）及び前後方向（Ｙ方向）のそれぞれの中心となる位置に接合用孔５１３が形成されている。 Next, the receiving body A2 of the second embodiment of the roof receiving device A in the present invention is composed of a flat receiving top 53 and legs 52, 52 (see Figures 5 and 6 (A)). The flat receiving top 53 is formed flat. The flat receiving top 53 has a connection hole 513 formed at the center position in both the width direction (X direction) and the front-rear direction (Y direction).

該接合用孔５１３の箇所で、平坦状受頂部５３の下面側には、内ネジ部材６２が溶接手段によって固着されている。該内ネジ部材６２は、貫通孔の内周に内ネジ６２ａが形成された部材であって、具体的にはナットが使用されることが好適である。また、内ネジ部材６２は、特に図示しないが、直方体又は扁平直方体等の金属材に内ネジ６２ａが形成された部材であっても構わない。 At the joining hole 513, an internally threaded member 62 is fixed by welding to the underside of the flat receiving top 53. The internally threaded member 62 is a member in which an internal thread 62a is formed on the inner circumference of a through hole, and specifically, a nut is preferably used. Although not shown, the internally threaded member 62 may also be a member in which an internal thread 62a is formed in a metal material such as a rectangular parallelepiped or flat rectangular parallelepiped.

そして、接合用孔５１３には、ボルトとした前記連結用ボルト６１が貫通可能であり、内ネジ部材６２とを介して、嵌合吊子８５が、嵌合取付部材Ａ1が受本体Ａ2に連結される。ボルトとした連結用ボルト６１の先端は、嵌合取付部材Ａの平坦状頂部２６に形成された連結用固定孔２６ａに挿入する。前記脚部５２，５２は、前記受頂部５１の幅方向（Ｘ方向）両端から外方下向きに傾斜するようにして形成されたものである。 The connecting bolt 61 can pass through the joining hole 513, and the fitting retainer 85 connects the fitting mounting member A1 to the receiving body A2 via the internal thread member 62. The tip of the connecting bolt 61 is inserted into the connecting fixing hole 26a formed in the flat top 26 of the fitting mounting member A. The legs 52, 52 are formed so as to be inclined outward and downward from both ends of the receiving top 51 in the width direction (X direction).

そして、嵌合取付部材Ａ1の膨出部２の開口２ｋから受本体Ａ2の平坦状受頂部５３が挿入され、嵌合取付部材Ａ1の平坦状頂部２６と、受本体Ａ2の平坦状受頂部５３とが溶接固着される。この溶接固着箇所は、第１実施形態と同様に溶接固着部Ａｗと称する。溶接固着部Ａｗにおける溶接個の具体的な位置は、嵌合取付部材Ａ1の平坦状受頂部５３と、受本体Ａ2の平坦状受頂部５３との接触面同士であり、この部分で溶接が行われる。 Then, the flat top 53 of the receiving body A2 is inserted through the opening 2k of the bulge 2 of the fitting attachment member A1, and the flat top 26 of the fitting attachment member A1 and the flat top 53 of the receiving body A2 are welded together. This welded attachment point is called the welded attachment portion Aw, as in the first embodiment. The specific location of the weld at the welded attachment portion Aw is the contact surface between the flat top 53 of the fitting attachment member A1 and the flat top 53 of the receiving body A2, and welding is performed at this portion.

具体的には、嵌合取付部材Ａ1の平坦状頂部２６と、受本体Ａ2の平坦状受頂部５３の同士で溶接され、且つその溶接位置は、平坦状頂面部２６の幅方向（Ｘ方向）であって、吊子装着用孔２８を中心として、そのＸ方向両側に溶接固着部Ａｗがそれぞれ設けられるものである（図５参照）。また、両前記溶接固着部Ａｗは、スポット溶接とすることが好ましいが、シーム溶接とすることもある。 Specifically, the flat top 26 of the fitting attachment member A1 and the flat top 53 of the receiving body A2 are welded together, and the welding position is in the width direction (X direction) of the flat top surface 26, with the retaining clip attachment hole 28 at the center, and welded and fixed parts Aw are provided on both sides in the X direction (see Figure 5). In addition, both of the welded and fixed parts Aw are preferably spot welded, but may also be seam welded.

次に、本発明における屋根用受具Ａの第２実施形態の嵌合取付部材Ａ1に対応する嵌合タイプの折板屋根Ｂ2について説明する。この嵌合タイプの折板屋根Ｂ2は、主に、折板屋根板８と、嵌合キャップ材８６と、嵌合吊子８５とが備わっている。この嵌合タイプの折板屋根板８では、主板８１の幅方向両側に傾斜状の立上り部８２，８２が形成され、その上端に前記嵌合キャップ材８６と嵌合する嵌合連結頂部８３ｃ，８３ｃが形成されている〔図６（Ｂ），（Ｃ）参照〕。 Next, we will explain the fitting type folded plate roof B2, which corresponds to the fitting attachment member A1 of the second embodiment of the roof support A in this invention. This fitting type folded plate roof B2 mainly comprises a folded plate roof panel 8, a fitting cap material 86, and a fitting retaining clip 85. In this fitting type folded plate roof panel 8, inclined rising parts 82, 82 are formed on both sides of the width direction of the main panel 81, and fitting connecting top parts 83c, 83c that fit with the fitting cap material 86 are formed at the upper ends of the parts [see Figures 6 (B) and (C)].

嵌合吊子８５は、略直方体状の筐体部８５ａの幅方向（Ｘ方向）両側から舌片８５ｂ，８５ｂが形成されている〔図６（Ａ）参照〕。筐体部８５ａの底部には、連結用ボルト６１が貫通する貫通孔が形成されている。そして、嵌合取付部材Ａの頂部２１上に嵌合吊子８５を配置し、受本体Ａ2の受頂部５１と、嵌合取付部材Ａ1とを連結用ボルト６１と内ネジ部材６２とで固着する。 The fitting retainer 85 has tongue pieces 85b, 85b formed on both sides in the width direction (X direction) of the roughly rectangular parallelepiped housing part 85a [see FIG. 6 (A)]. A through hole is formed in the bottom of the housing part 85a, through which the connecting bolt 61 passes. The fitting retainer 85 is then placed on the top 21 of the fitting attachment member A, and the receiving top 51 of the receiving body A2 and the fitting attachment member A1 are fixed with the connecting bolt 61 and the internal thread member 62.

そして、嵌合吊子８５の両側に隣接する折板屋根用板８，８を配置し、前記嵌合連結頂部８３ｃ，８３ｃが嵌合吊子８５の筐体部８５ａの幅方向(Ｘ方向)両側に形成された舌片８５ｂ，８５ｂによって巻き付け固定され、隣接する両前記嵌合連結頂部８３ｃ，８３ｃ上に嵌合キャップ材８６が嵌合によって被せられる。これを、順次繰り返して嵌合キャップ材８６を使用した嵌合タイプの折板屋根Ｂ2が施工される。 Then, adjacent folded roof panels 8, 8 are placed on both sides of the fitting retainer 85, and the fitting connecting tops 83c, 83c are wrapped and fixed by the tongue pieces 85b, 85b formed on both sides of the width direction (X direction) of the housing part 85a of the fitting retainer 85, and the fitting cap material 86 is fitted over the adjacent fitting connecting tops 83c, 83c. This is repeated in sequence to construct a fitting type folded roof B2 using the fitting cap material 86.
