図2に示されるように、羽根部材22(なお、羽根部材24については後述する)の回転中心側となる、上弦材26及び下弦材28の一端部及び屋根ユニット12の上弦材16及び下弦材18には、クランク形状を成す蝶番(支持手段)32がそれぞれ取付けられている。   As shown in FIG. 2, one end of the upper chord member 26 and the lower chord member 28 and the upper chord member 16 and the lower chord member of the roof unit 12, which are on the rotation center side of the blade member 22 (the blade member 24 will be described later). A hinge (supporting means) 32 having a crank shape is attached to 18.

具体的には、羽根部材22の上弦材26及び下弦材28が、屋根ユニット12の上弦材16及び下弦材18と重なった状態で、上弦材26及び下弦材28の一端部のウエブ26A、28A(上弦材16、下弦材18の反対側となる面)には、蝶番32の一端部32Aがそれぞれ取付けられている。このように、羽根部材22の上弦材26及び下弦材28が、屋根ユニット12の上弦材16及び下弦材18と重なった状態が、屋根ユニット12の長手方向の側面から張出す前の状態であり、以下、「羽根部材22が閉じた状態」という。   Specifically, the webs 26A and 28A at one end of the upper chord member 26 and the lower chord member 28 in a state where the upper chord member 26 and the lower chord member 28 of the blade member 22 overlap the upper chord member 16 and the lower chord member 18 of the roof unit 12. One end 32 </ b> A of a hinge 32 is attached to each (surface opposite to the upper chord member 16 and the lower chord member 18). Thus, the state in which the upper chord material 26 and the lower chord material 28 of the blade member 22 overlap the upper chord material 16 and the lower chord material 18 of the roof unit 12 is a state before projecting from the side surface in the longitudinal direction of the roof unit 12. Hereinafter, it is referred to as “a state where the blade member 22 is closed”.

そして、蝶番32の中央部32Bが、上弦材26、下弦材28の先端面にそれぞれ面接触し、蝶番32の他端部32Cが、屋根ユニット12の上弦材16、下弦材18のウエブ16A、18Aにそれぞれ取付けられている。蝶番32の中央部32Bと他端部32Cの間には、蝶番32のヒンジ部32Dが設けられており、このヒンジ部32Dを中心に羽根部材22が回転する。   The central portion 32B of the hinge 32 is in surface contact with the tip surfaces of the upper chord member 26 and the lower chord member 28, and the other end portion 32C of the hinge 32 is the web 16A of the upper chord member 16 and the lower chord member 18 of the roof unit 12. Each is attached to 18A. A hinge portion 32D of the hinge 32 is provided between the central portion 32B and the other end portion 32C of the hinge 32, and the blade member 22 rotates around the hinge portion 32D.

以上のような構成により、羽根部材22は閉じた状態から、図3に示されるように、羽根部材22の上弦材26及び下弦材28が、屋根ユニット12の長手方向の側面から張出し、屋根ユニット12の上弦材16及び下弦材18に対して直交した状態(以下、「羽根部材22が完全開放された状態」という)となるまで回転する。つまり、蝶番32の他端部32Cと中央部32Bとが直角を成した状態から、蝶番32の中央部32Bと他端部32Cとが面接触して羽根部材22の回転中心側の移動が規制されるまで、羽根部材22は回転する。   With the configuration as described above, the upper chord member 26 and the lower chord member 28 of the blade member 22 project from the side surface in the longitudinal direction of the roof unit 12 as shown in FIG. 12 is rotated until it becomes a state orthogonal to the upper chord member 16 and the lower chord member 18 (hereinafter referred to as “the state in which the blade member 22 is fully opened”). That is, from the state in which the other end portion 32C and the central portion 32B of the hinge 32 form a right angle, the central portion 32B and the other end portion 32C of the hinge 32 are in surface contact and the movement of the blade member 22 on the rotational center side is restricted. The blade member 22 rotates until it is done.

なお、ここでは、クランク形状の蝶番32を用いたが、羽根部材22を所定の角度内(ここでは、0〜90°)で回転させることができれば良いため、蝶番32の形状は特に限定されるものではなく、平板状やL字形状の蝶番を用いても良い。   Although the crank-shaped hinge 32 is used here, the shape of the hinge 32 is particularly limited as long as the blade member 22 can be rotated within a predetermined angle (here, 0 to 90 °). Instead of a flat plate, an L-shaped hinge may be used.

一方、図4に示されるように、屋根ユニット12の長手方向の一端面には、羽根部材24が回転可能に設けられている。この羽根部材24の回転中心側となる、上弦材26及び下弦材28の一端面には、L字状を成す蝶番(支持手段)33の一端部33Aがそれぞれ取付けられており、蝶番33の他端部33Bは、屋根ユニット12の長手方向の上弦材16及び下弦材18の端面にそれぞれ取付けられている。   On the other hand, as shown in FIG. 4, a blade member 24 is rotatably provided on one end surface of the roof unit 12 in the longitudinal direction. One end portions 33A of L-shaped hinges (supporting means) 33 are attached to one end surfaces of the upper chord member 26 and the lower chord member 28 on the rotation center side of the blade member 24. The end portions 33 </ b> B are respectively attached to the end surfaces of the upper chord material 16 and the lower chord material 18 in the longitudinal direction of the roof unit 12.

ここでは、蝶番33の中央部がヒンジ部33Cとなっており、当該ヒンジ部33Cを中心に、羽根部材24の上弦材26及び下弦材28が、仮想線で示されるように、屋根ユニット12の上弦材17及び下弦材19と重なった状態(以下、「羽根部材24が閉じた状態」という)から、実線で示されるように、屋根ユニット12の上弦材17及び下弦材19の同一直線状にそれぞれ配置された状態(以下、「羽根部材24が完全開放された状態」という)となるまで羽根部材24は回転する。つまり、蝶番33の一端部33Aが、上弦材16及び下弦材18のウエブ16A、18Aに面接触して羽根部材24の回転中心側の移動が規制されるまで、羽根部材24は回転する。   Here, the central portion of the hinge 33 is a hinge portion 33C, and the upper chord material 26 and the lower chord material 28 of the blade member 24 are centered on the hinge portion 33C, so that the roof unit 12 From the state where it overlaps with the upper chord material 17 and the lower chord material 19 (hereinafter referred to as “the blade member 24 is closed”), the upper chord material 17 and the lower chord material 19 of the roof unit 12 are aligned in a straight line as shown by the solid line. The blade members 24 rotate until they are arranged (hereinafter referred to as “the blade member 24 is fully opened”). That is, the blade member 24 rotates until the one end portion 33A of the hinge 33 comes into surface contact with the webs 16A, 18A of the upper chord member 16 and the lower chord member 18 and movement of the blade member 24 on the rotation center side is restricted.

したがって、屋根ユニット12の長手方向に沿って配置された羽根部材22が90°回転するのに対して、屋根ユニット12の長手方向の一端面に配置された羽根部材22は180°回転する。そして、これにより、屋根ユニット12の長手方向の両端部及びその間に羽根部材22が配置されることとなる。   Accordingly, the blade member 22 disposed along the longitudinal direction of the roof unit 12 rotates 90 °, whereas the blade member 22 disposed on one end surface of the roof unit 12 in the longitudinal direction rotates 180 °. And thereby, the blade member 22 will be arrange | positioned among the both ends of the longitudinal direction of the roof unit 12, and between them.

なお、ここでは、図1に示されるように、羽根部材22は4つ用いられているが、屋根ユニット12の長さによってその数は変わる。また、ここでは蝶番32、33を用いて羽根部材22、24をそれぞれ回転可能としたが、屋根ユニット12の側面に対して、羽根部材22、24を回転させることができれば良いため、これに限るものではない。   Here, as shown in FIG. 1, four blade members 22 are used, but the number varies depending on the length of the roof unit 12. Further, here, the blade members 22 and 24 can be rotated by using the hinges 32 and 33, respectively, but the blade members 22 and 24 may be rotated with respect to the side surface of the roof unit 12, so that the present invention is limited thereto. It is not a thing.

例えば、図示はしないが、屋根ユニット12の上弦材16及び下弦材18側(或いは羽根部材22の上弦材26及び下弦材28側)にシャフト又はピンを設け、羽根部材22、24の上弦材26及び下弦材28側(或いは屋根ユニット12の上弦材16及び下弦材18側)に、当該シャフト又はピンを回転可能に支持する軸孔が形成された軸板を設けて、羽根部材22、24が回転可能となるようにしても良い。   For example, although not shown, a shaft or a pin is provided on the upper chord material 16 and lower chord material 18 side (or the upper chord material 26 and lower chord material 28 side) of the roof unit 12, and the upper chord material 26 of the blade members 22 and 24 is provided. A shaft plate in which a shaft hole for rotatably supporting the shaft or pin is provided on the lower chord member 28 side (or on the upper chord member 16 and lower chord member 18 side) of the roof unit 12, and the blade members 22 and 24 are provided. It may be configured to be rotatable.

以上のように、本実施形態では、屋根ユニット12に対して羽根部材22、24を回転可能に支持したが、屋根ユニット12の輸送時や建込み時においては、図2に示されるように、羽根部材22が閉じた状態となるようにする。   As described above, in the present embodiment, the blade members 22 and 24 are rotatably supported with respect to the roof unit 12, but when the roof unit 12 is transported or built, as shown in FIG. The blade member 22 is closed.

例えば、屋根ユニット12の上弦材及び羽根部材22の上弦材26、屋根ユニット12の下弦材18及び羽根部材22の下弦材28の幅と略同一の幅を有するコ字状の被せ材(係止手段)38を用いて、当該被せ材38を上弦材16及び上弦材26、下弦材18及び下弦材28の上部にそれぞれ嵌め込むようにする。これにより、羽根部材22は閉じた状態のまま保持される。   For example, the upper chord member of the roof unit 12 and the upper chord member 26 of the blade member 22, the lower chord member 18 of the roof unit 12, and the lower chord member 28 of the blade member 22 having a substantially U-shaped width (locking) Means) 38 is fitted into the upper chord material 16 and the upper chord material 26, the lower chord material 18 and the lower chord material 28, respectively. Thereby, the blade member 22 is held in a closed state.

一方、図3に示されるように、屋根ユニット12には、束材20が設けられているが、羽根部材22、24を所定角度(ここでは90°、180°)回転させた状態で、羽根部材22の上弦材26及び下弦材28の一端部のウエブ26A、28Aが、束材20のフランジ20Aに面接触可能となるように配置されている。   On the other hand, as shown in FIG. 3, the roof unit 12 is provided with a bundle member 20, but the blade member 22, 24 is rotated by a predetermined angle (here, 90 °, 180 °), and the blade The webs 26 </ b> A and 28 </ b> A at one end of the upper chord member 26 and the lower chord member 28 of the member 22 are arranged so as to be in surface contact with the flange 20 </ b> A of the bundle member 20.

そして、蝶番32の中央部32Bと他端部32Cが面接触した状態、または、蝶番33の一端部33Aが、上弦材16及び下弦材18のウエブ16A、18Aに面接触した状態では、羽根部材22、24の上弦材26及び下弦材28が、束材20のフランジ20Aにそれぞれ面接触する。   When the central portion 32B and the other end portion 32C of the hinge 32 are in surface contact, or when the one end portion 33A of the hinge 33 is in surface contact with the webs 16A and 18A of the upper chord member 16 and the lower chord member 18, the blade member The upper chord member 26 and the lower chord member 28 are in surface contact with the flange 20A of the bundle member 20, respectively.

ここで、屋根ユニット13は、屋根ユニット12との間に羽根部材22、24(なお、羽根部材24の図示は省略する)が配置可能な隙間を置いて配置され、屋根ユニット12の束材20と対面する位置には、屋根ユニット13の束材34が配置されている。   Here, the roof unit 13 is disposed with a gap in which the blade members 22 and 24 (illustration of the blade member 24 is omitted) can be disposed between the roof unit 12 and the bundle unit 20 of the roof unit 12. A bundle member 34 of the roof unit 13 is disposed at a position facing the front side.

このため、羽根部材22、24の回転中心側に位置する上弦材26及び下弦材28の一端部が束材20のフランジ20Aに面接触した状態で、羽根部材22、24の自由端側に位置する上弦材26及び下弦材28の他端部が束材34のフランジ34Aに面接触する。   Therefore, the upper chord member 26 and the lower chord member 28 located on the rotation center side of the blade members 22 and 24 are positioned on the free end side of the blade members 22 and 24 in a state where the end portions of the upper chord member 26 and the lower chord member 28 are in surface contact with the flange 20A of the bundle member 20. The other ends of the upper chord member 26 and the lower chord member 28 are in surface contact with the flange 34A of the bundle member 34.

つまり、羽根部材22、24はその回転中心側及び自由端側が、それぞれ束材20、34に当接して羽根部材22、24は張り出し方向への移動が規制される。この状態で、羽根部材22、24の上弦材26及び下弦材28の自由端部が束材34に留め付けられる(固定される)。   That is, the blade members 22 and 24 have their rotation center side and free end side in contact with the bundle members 20 and 34, respectively, so that the blade members 22 and 24 are restricted from moving in the protruding direction. In this state, the free ends of the upper chord member 26 and the lower chord member 28 of the blade members 22 and 24 are fastened (fixed) to the bundle member 34.

(作用・効果) (Action / Effect)

次に、本実施形態に係る屋根ユニット12について、その作用・効果を説明する。   Next, the operation and effect of the roof unit 12 according to the present embodiment will be described.

本実施形態では、図1及び図5(A)に示されるように、屋根ユニット12の側面に羽根部材22を回転可能に支持している。このため、屋根ユニット12の輸送時や建込み時においては、図2に示されるように、コ字状の被せ材38を用いて、当該被せ材38を上弦材16及び上弦材26、下弦材18及び下弦材28の上部にそれぞれ嵌め込むことで、屋根ユニット12の輸送時や建込み時に羽根部材22の回転を防止し、羽根部材22が邪魔にならないようにすることができる。したがって、作業性が良い。   In this embodiment, as shown in FIGS. 1 and 5A, the blade member 22 is rotatably supported on the side surface of the roof unit 12. Therefore, when the roof unit 12 is transported or built, as shown in FIG. 2, a U-shaped covering material 38 is used, and the covering material 38 is used as the upper chord material 16, the upper chord material 26, and the lower chord material. The blade member 22 can be prevented from rotating at the time of transporting or erection of the roof unit 12, and the blade member 22 can be prevented from getting in the way by being fitted into the upper portions of the 18 and the lower chord material 28, respectively. Therefore, workability is good.

一方、羽根部材22を構成する斜材30はここでは2本用いられており、下弦材28から上弦材26へ行くにしたがって斜材30の上端部が互いに近接する方向へ傾斜している。そして、斜材30の上端部同士の間には、隙間が設けられている。この隙間内に、被せ材38を嵌め込むようにする。この被せ材38を隙間に合わせて形成し、被せ材38の両端部が斜材30の上端部に接触するようにする。これにより、被せ材38は上弦材16の延出方向に沿った移動(矢印方向の移動)が規制され、結果的に、屋根ユニット12の長手方向に沿った羽根部材22の移動が規制される。   On the other hand, two diagonal members 30 constituting the blade member 22 are used here, and the upper ends of the diagonal members 30 are inclined toward each other as they go from the lower chord member 28 to the upper chord member 26. A gap is provided between the upper ends of the diagonal member 30. The covering material 38 is fitted into the gap. The covering material 38 is formed in accordance with the gap so that both end portions of the covering material 38 are in contact with the upper end portion of the diagonal member 30. Thereby, the movement of the covering material 38 along the extending direction of the upper chord material 16 (movement in the arrow direction) is restricted, and as a result, the movement of the blade member 22 along the longitudinal direction of the roof unit 12 is restricted. .

ところで、屋根ユニット12の上面には、工場内において、予め屋根葺材14(図1参照)が留め付けられているが、羽根部材22の屋根葺材15は、建築地において留め付けされる。このため、羽根部材22の屋根葺材15は屋根ユニット12の屋根葺材14の上面に重ねて配置され、この状態のまま輸送される。   By the way, on the upper surface of the roof unit 12, the roof covering material 14 (see FIG. 1) is fastened in advance in the factory, but the roof covering material 15 of the blade member 22 is fastened in the building area. For this reason, the roof covering material 15 of the blade member 22 is arranged on the upper surface of the roof covering material 14 of the roof unit 12 and is transported in this state.

本実施形態では、建築地において、図1及び図5(A)に示されるように、屋根ユニット12を配置(第1屋根ユニット配置工程)した後、この屋根ユニット12との間に隙間を空けて屋根ユニット13を配置する(第2屋根ユニット配置工程)。   In the present embodiment, as shown in FIGS. 1 and 5A, after the roof unit 12 is arranged (first roof unit arranging step) in the building site, a gap is formed between the roof unit 12 and the roof unit 12. The roof unit 13 is arranged (second roof unit arranging step).

そして、屋根ユニット12の羽根部材22を回転させて、当該隙間に配置し、羽根部材22の上弦材26及び下弦材28の自由端部を屋根ユニット13の束材34にそれぞれ留め付ける(羽根部材固定工程)。   Then, the blade member 22 of the roof unit 12 is rotated and arranged in the gap, and the free ends of the upper chord member 26 and the lower chord member 28 of the blade member 22 are fastened to the bundle member 34 of the roof unit 13 (blade member). Fixing process).

次に、屋根ユニット12の屋根葺材14の上面に配置された屋根葺材15を屋根ユニット12から水平移動させて羽根部材22、24の上面へ配置し、タッピンネジなどによって羽根部材22、24の上面に屋根葺材15を留め付ける(屋根葺材固定工程)。   Next, the roof covering material 15 arranged on the upper surface of the roof covering member 14 of the roof unit 12 is horizontally moved from the roof unit 12 and placed on the upper face of the blade members 22 and 24, and is placed on the upper face of the blade members 22 and 24 by a tapping screw or the like. The roof covering 15 is fastened (roof covering fixing process).

通常のユニット屋根100では、図5(B)に示されるように、屋根ユニット102と屋根ユニット102を隣接させた状態で並設し、互いに建付けてユニット屋根100を形成するが、この場合、屋根ユニット102の上弦材104、下弦材及び束材と屋根ユニット102の上弦材104、下弦材及び束材などが隣り合った状態で配置されることとなり、これらの部品が重複し、結果的に、部品点数が多くなってしまう。   In the normal unit roof 100, as shown in FIG. 5B, the roof unit 102 and the roof unit 102 are juxtaposed in a state where they are adjacent to each other, and are built together to form the unit roof 100. The upper chord material 104, the lower chord material and the bundle material of the roof unit 102 and the upper chord material 104, the lower chord material, the bundle material and the like of the roof unit 102 are arranged adjacent to each other. The number of parts will increase.

しかし、本実施形態では、図5(A)に示されるように、屋根ユニット12と屋根ユニット13の間に羽根部材22、24を配置することで、屋根ユニット12と屋根ユニット13とが隣接して配置されることはなく、上弦材16及び下弦材18等の部品が重複することはない。このため、部材費を削減することができる。   However, in this embodiment, as shown in FIG. 5A, the roof unit 12 and the roof unit 13 are adjacent to each other by arranging the blade members 22 and 24 between the roof unit 12 and the roof unit 13. The parts such as the upper chord member 16 and the lower chord member 18 do not overlap each other. For this reason, member costs can be reduced.

また、本実施形態では、屋根ユニット12を少なくとも一つ置きに配置するため、その分屋根ユニット12の数量が削減される。これによると、屋根ユニットの数量が少なくなるため、積載費が減少し、また、輸送台数が減り輸送費が削減される。また、屋根ユニット12の数量が少なくなるため、取付部材の減少により施工が容易になり、施工費が削減される。さらに、作業工数が削減される分、工期が短縮される。   In the present embodiment, since at least every other roof unit 12 is arranged, the number of roof units 12 is reduced accordingly. According to this, since the number of roof units is reduced, the loading cost is reduced, and the number of transported units is reduced to reduce the transportation cost. In addition, since the number of roof units 12 is reduced, construction is facilitated by reducing the number of attachment members, and construction costs are reduced. Furthermore, the work period is shortened by the amount of work man-hours reduced.

(その他の実施形態) (Other embodiments)

(1) ところで、図3に示されるように、束材20、34のリップ側は開口となっている。このため、図6に示されるように、羽根部材22の上弦材26及び下弦材28の自由端側に、束材34のリップ34Bに係止され羽根部材22を移動規制する規制金物(規制手段)40を取付けても良い。 (1) By the way, as FIG. 3 shows, the lip side of the bundle materials 20 and 34 is an opening. For this reason, as shown in FIG. 6, on the free end side of the upper chord member 26 and the lower chord member 28 of the blade member 22, a restriction metal (restricting means) that is locked to the lip 34 </ b> B of the bundle member 34 and restricts the movement of the blade member 22. 40) may be attached.

例えば、この規制金物40は平面視で略L字状を成しており、一端部40Aが上弦材26及び下弦材28に取付けられ、他端部40Bは上弦材26及び下弦材28のウエブ26A、28Aの表面から張出し、先端部には爪部42が形成されている。この爪部42の移動軌跡上に束材34のリップ34Bが配置され、束材34のリップ34Bの先端部に爪部42が係止される。   For example, the regulation hardware 40 is substantially L-shaped in plan view, and one end 40A is attached to the upper chord material 26 and the lower chord material 28, and the other end 40B is the web 26A of the upper chord material 26 and the lower chord material 28. , 28A, and a claw portion 42 is formed at the tip. The lip 34B of the bundle 34 is disposed on the movement locus of the claw 42, and the claw 42 is locked to the tip of the lip 34B of the bundle 34.

これによると、図7に示されるように、羽根部材22を回転させて、羽根部材22の自由端部が束材34に当接するとき、規制金物40の爪部42が束材34のリップ34Bの先端部に係止される(羽根部材22がいわゆる仮止めされる)。このため、この後、羽根部材22を隣の屋根ユニット13に留め付ける際に、羽根部材22が移動しないので作業性が良い。   According to this, as shown in FIG. 7, when the blade member 22 is rotated and the free end portion of the blade member 22 comes into contact with the bundle member 34, the claw portion 42 of the restriction metal 40 is the lip 34 </ b> B of the bundle member 34. (The blade member 22 is temporarily fixed). For this reason, after that, when the blade member 22 is fastened to the adjacent roof unit 13, the blade member 22 does not move, so that workability is good.

(2) なお、ここでは、羽根部材22の自由端側を束材34に仮止めさせることができれば良いためこれに限るものではない。例えば、図8(A)に示すように、羽根部材22の上弦材26及び下弦材28(なお、下弦材28については図示を省略している)の自由端側のウエブ26A、28Aに円錐状の突起部(接続手段)44を設ける。この突起部44は中空部を備えており、複数の三角状の板バネを並べて円錐形状を形成し、弾性変形可能とする。この突起部44を束材34のフランジ34Aに形成された孔部(接続手段)46へ係合させるようにしても良い。 (2) Here, the free end side of the blade member 22 only needs to be temporarily fixed to the bundle member 34, and the present invention is not limited to this. For example, as shown in FIG. 8A, the webs 26A and 28A on the free ends of the upper chord member 26 and the lower chord member 28 (not shown for the lower chord member 28) of the blade member 22 are conical. Protrusion (connecting means) 44 is provided. The protrusion 44 has a hollow portion, and a plurality of triangular leaf springs are arranged to form a conical shape, which can be elastically deformed. The protrusion 44 may be engaged with a hole (connection means) 46 formed in the flange 34A of the bundle 34.

孔部46を通過するときは、突起部44は縮径され孔部46を通過し、突起部44が孔部46を通過すると、突起部44は復元して孔部46の周辺部に係止される。つまり、屋根ユニット13に対して羽根部材22をいわゆるワンタッチで接続させることができ、作業性が向上する。   When passing through the hole 46, the projection 44 is reduced in diameter and passes through the hole 46. When the projection 44 passes through the hole 46, the projection 44 is restored and locked to the periphery of the hole 46. Is done. That is, the blade member 22 can be connected to the roof unit 13 by so-called one-touch, and workability is improved.

また、これ以外にも、図8(B)に示されるように、羽根部材22の上弦材26及び下弦材28の自由端側のウエブ26A、28Aに突起部(接続手段)48を設け、該突起部48を塑性変形させて、束材34のフランジ34Aに形成された孔部46へ係止させるようにしても良い。   In addition to this, as shown in FIG. 8B, protrusions (connection means) 48 are provided on the webs 26A, 28A on the free ends of the upper chord member 26 and the lower chord member 28 of the blade member 22, The protrusion 48 may be plastically deformed and locked to the hole 46 formed in the flange 34A of the bundle 34.

(3) 一方、本実施形態では、羽根部材22を屋根ユニット12の側面に対して直交させるように配置したが、図9に示されるように、屋根ユニット12と屋根ユニット13の隙間(羽根部材22のトラススパン)が、基準寸法であるモジュールMよりも狭い(M’)場合にも対応させることができる。 (3) On the other hand, in the present embodiment, the blade member 22 is arranged so as to be orthogonal to the side surface of the roof unit 12, but as shown in FIG. 9, the gap (blade member) between the roof unit 12 and the roof unit 13. 22 truss spans) (M ′) that are narrower than the reference dimension module M can also be accommodated.

この場合、束材(調整手段)20、34のウエブ20B、34Bに対するフランジ20A、34Aの角度を変えて、フランジ20A、34Aの表面に羽根部材22の上弦材26及び下弦材28がそれぞれ面接触可能となるようにする。束材20、34のフランジ20A、34Aの表面に、羽根部材22の上弦材26、下弦材28がそれぞれ面接触した状態で、上弦材26、下弦材28を束材20、34に留め付ける。   In this case, the angle of the flanges 20A and 34A with respect to the webs 20B and 34B of the bundle members (adjusting means) 20 and 34 is changed, and the upper chord member 26 and the lower chord member 28 are in surface contact with the surfaces of the flanges 20A and 34A, respectively. Make it possible. The upper chord member 26 and the lower chord member 28 are fastened to the bundle members 20 and 34 in a state where the upper chord member 26 and the lower chord member 28 are in surface contact with the surfaces of the flanges 20A and 34A of the bundle members 20 and 34, respectively.

つまり、ここでは、束材20、34の変形によって、羽根部材22の固定位置を変え、羽根部材22の長さを変えずに、当該羽根部材22を屋根ユニット12の側面に対して傾斜させた状態で配置することで、寸法差(t)分を吸収できるようにして、屋根ユニット12と屋根ユニット13の間で設けられる隙間の幅変更に対応することができる。   That is, here, the deformation of the bundle members 20, 34 changes the fixing position of the blade member 22, and the blade member 22 is inclined with respect to the side surface of the roof unit 12 without changing the length of the blade member 22. By arranging in a state, it is possible to absorb the dimensional difference (t) and cope with a change in the width of the gap provided between the roof unit 12 and the roof unit 13.

(4) また、本実施形態では、屋根ユニット12の長手方向の一側面に羽根部材22を設けたが、図10に示されるように、ユニット屋根10の中央に配置される屋根ユニット25では、当該屋根ユニット25の長手方向の両側面に羽根部材22、23を設けても良い。 (4) Moreover, in this embodiment, although the blade member 22 was provided in the one side surface of the longitudinal direction of the roof unit 12, as FIG. 10 shows, in the roof unit 25 arrange | positioned in the center of the unit roof 10, The blade members 22 and 23 may be provided on both side surfaces in the longitudinal direction of the roof unit 25.

この場合、羽根部材22の自由端部と羽根部材23の自由端部を連結させる必要があるが、例えば、図11(A)、(B)に示されるように、輸送時に用いる被せ材39を、建込み時において、羽根部材22、23の自由端部に被せ、互いに留め付けるようにしても良い。   In this case, it is necessary to connect the free end portion of the blade member 22 and the free end portion of the blade member 23. For example, as shown in FIGS. At the time of erection, the free end portions of the blade members 22 and 23 may be covered and fastened to each other.

この被せ材39には、予めボルト45などの留め付け具が挿通可能な孔部39Aが形成され、羽根部材22、23の上弦材26及び下弦材28(なお、下弦材28については図示を省略している)の自由端部には、被せ材39の孔部39Aと対応する孔部47が形成される。そして、羽根部材22、23の自由端部に被せ材39を留め付け、羽根部材22の自由端部と羽根部材23の自由端部を連結させる。   A hole 39A into which a fastener such as a bolt 45 can be inserted is formed in the covering member 39 in advance, and the upper chord member 26 and the lower chord member 28 of the blade members 22 and 23 (the lower chord member 28 is not shown). A hole 47 corresponding to the hole 39 </ b> A of the covering material 39 is formed at the free end. Then, the covering material 39 is fastened to the free ends of the blade members 22 and 23, and the free ends of the blade member 22 and the free ends of the blade member 23 are connected.

これにより、この被せ材38を輸送時の係止部材としてだけではなく、連結部材としても兼用することができる。勿論、別途連結金物を用いて羽根部材22の自由端部と羽根部材23の自由端部を互いに連結させるようにしても良い。   Thereby, this covering material 38 can be used not only as a locking member during transportation but also as a connecting member. Of course, you may make it connect the free end part of the blade member 22 and the free end part of the blade member 23 mutually using connection hardware separately.

これによれば、ユニット屋根10の中央では、屋根ユニット12を二つ置きに配置することができ、一つ置きに配置する場合と比較して、さらに屋根ユニット12が不要となり、その分の積載費、施工費等が削減される。なお、ここでは、羽根部材22の自由端部と羽根部材23の自由端部を連結させるため、羽根部材22、23自体を強化することが望ましく、例えば、羽根部材22、23の自由端部には束材49を設ける。   According to this, in the center of the unit roof 10, every two roof units 12 can be arranged, and compared with the case where every other roof unit 12 is arranged, the roof unit 12 becomes unnecessary, and the load corresponding to that. Costs and construction costs are reduced. Here, in order to connect the free end portion of the blade member 22 and the free end portion of the blade member 23, it is desirable to reinforce the blade members 22, 23 themselves. Provides a bundle 49.

(5) また、本実施形態では、屋根ユニット12の側面に羽根部材22を設け、当該羽根部材22を水平方向に沿って回転可能に支持するようにしたが、屋根ユニット12の側面から羽根部材22を張出させるようにすることができればよいため、これに限るものではない。 (5) In the present embodiment, the blade member 22 is provided on the side surface of the roof unit 12 and the blade member 22 is rotatably supported along the horizontal direction. Since it is only necessary to be able to project 22, the present invention is not limited to this.

例えば、図示はしないが、屋根ユニット12の幅方向に沿って羽根部材22をスライドさせるようにしても良い。また、羽根部材22のスライド方向先端部に位置する上弦材16に、クランプ金物(連動手段)を取付けて、屋根ユニット12の屋根葺材14の上に配置された屋根葺材15(図1参照)をクランプし、羽根部材22の移動に連動して、当該屋根葺材15をスライドさせるようにしても良い。   For example, although not shown, the blade member 22 may be slid along the width direction of the roof unit 12. Further, a clamp member (interlocking means) is attached to the upper chord member 16 located at the tip of the blade member 22 in the sliding direction, and the roof member 15 (see FIG. 1) disposed on the roof member 14 of the roof unit 12 is attached. It is possible to clamp and slide the roof covering 15 in conjunction with the movement of the blade member 22.

この場合、羽根部材22と屋根葺材15を同時に移動させることができるため、羽根部材22を屋根ユニット13に固定させた後、屋根葺材15を羽根部材22の上に配置する場合と比較して、作業性が向上する。なお、ここでは、屋根葺材14、15の形状を断面波形状としているが、屋根葺材14、15の形状はこれに限るものではない。   In this case, since the blade member 22 and the roof covering material 15 can be moved simultaneously, after fixing the blade member 22 to the roof unit 13, compared with the case where the roof covering member 15 is arranged on the blade member 22, Workability is improved. In addition, although the shape of the roof covering materials 14 and 15 is made into the cross-sectional wave shape here, the shape of the roof covering materials 14 and 15 is not restricted to this.

<第2実施形態> Second Embodiment

次に、図12〜図14を参照して第2実施形態について説明する。なお、第1実施形態と略同一の内容については説明を省略する。   Next, a second embodiment will be described with reference to FIGS. In addition, description is abbreviate | omitted about the content substantially the same as 1st Embodiment.

第1実施形態では、羽根部材22を一つ一つ回転させるようにしたが、本実施形態では、リンク機構によって複数の羽根部材22を互いに連結させて、複数の羽根部材22を一度に回転させるようにした点に特徴がある。   In the first embodiment, the blade members 22 are rotated one by one. However, in the present embodiment, the plurality of blade members 22 are connected to each other by a link mechanism, and the plurality of blade members 22 are rotated at a time. There is a feature in this point.

具体的には、図12に示されるように、各羽根部材22の上弦材26の自由端側には、把持可能な板状の把持プレート(把持手段)50が取付けられている。各羽根部材22の各上弦材26の下部に位置するフランジ26Aには挿通孔52が形成されており、把持プレート50には挿通孔52と同じピッチで複数のピン54が固定され、これらのピン54がそれぞれ挿通孔52へ挿通されている。   Specifically, as shown in FIG. 12, a gripping plate-like gripping plate (grip means) 50 is attached to the free end side of the upper chord material 26 of each blade member 22. Insertion holes 52 are formed in the flanges 26A located below the upper chord members 26 of the blade members 22, and a plurality of pins 54 are fixed to the grip plate 50 at the same pitch as the insertion holes 52. 54 are respectively inserted into the insertion holes 52.

これにより、いわゆるリンク機構が構成され、各ピン54及び挿通孔52を介して、把持プレート50は羽根部材22の回転中心側を支点として回転すると共に、把持プレート50のピン54を中心に挿通孔52を介して羽根部材22の自由端側が回転し、把持プレート50との間で成す角度を変える。   As a result, a so-called link mechanism is configured, and the grip plate 50 rotates about the rotation center side of the blade member 22 via each pin 54 and the insertion hole 52, and the insertion hole about the pin 54 of the grip plate 50. The free end side of the blade member 22 is rotated via 52 to change the angle formed with the grip plate 50.

把持プレート50の内側(羽根部材22側)には、コ字状の切欠き部56が形成されている。この切欠き部56は、図13の実線で示されるように、羽根部材22が閉じた状態で、屋根ユニット12の束材20との干渉を回避するためのものである。   A U-shaped notch 56 is formed inside the grip plate 50 (on the blade member 22 side). This notch 56 is for avoiding interference with the bundle member 20 of the roof unit 12 in a state in which the blade member 22 is closed, as shown by a solid line in FIG.

また、把持プレート50の外側にもコ字状の切欠き部58が形成されている。この切欠き部58は、図14の実線で示されるように、羽根部材22が完全開放された状態で、屋根ユニット13の束材34との干渉を回避するためのものである。   In addition, a U-shaped notch 58 is also formed outside the grip plate 50. As shown by the solid line in FIG. 14, the notch 58 is for avoiding interference with the bundle 34 of the roof unit 13 in a state where the blade member 22 is completely opened.

なお、羽根部材22が完全開放された状態で、羽根部材22が束材34のフランジ34Aと面接触し、これにより、把持プレート50は移動規制されるが、このとき、切欠き部58が束材34のフランジ34Aと接触してもよい。   In the state where the blade member 22 is fully opened, the blade member 22 comes into surface contact with the flange 34A of the bundle member 34, and thereby the movement of the grip plate 50 is restricted, but at this time, the notch 58 is bundled. You may contact the flange 34A of the material 34.

また、把持プレート50の外側には、把持プレート50の表面から立設する規制片60が設けられている。この規制片60は、図12で示されるように、羽根部材22が完全開放された状態で、屋根ユニット13の上弦材16の内面側に係止可能とされる。つまり、把持プレート50を介して羽根部材22の仮止めが可能となる。   In addition, on the outside of the gripping plate 50, a regulating piece 60 is provided standing from the surface of the gripping plate 50. As shown in FIG. 12, the restriction piece 60 can be locked to the inner surface side of the upper chord material 16 of the roof unit 13 in a state where the blade member 22 is completely opened. That is, the blade member 22 can be temporarily fixed via the grip plate 50.

(作用・効果) (Action / Effect)

次に、本実施形態に係る屋根ユニット12について、その作用・効果を説明する。   Next, the operation and effect of the roof unit 12 according to the present embodiment will be described.

実施形態では、リンク機構を利用し、図13及び図14に示されるように、複数の羽根部材22を把持プレート50に連結している。これにより、図13の実線で示されるように、羽根部材22の閉じた状態では、羽根部材22の延出方向と把持プレート50の延出方向が同じになり、羽根部材22と把持プレート50は平行に配置される。   In the embodiment, a plurality of blade members 22 are coupled to the grip plate 50 using a link mechanism as shown in FIGS. 13 and 14. Thus, as shown by the solid line in FIG. 13, in the closed state of the blade member 22, the extending direction of the blade member 22 and the extending direction of the gripping plate 50 are the same, and the blade member 22 and the gripping plate 50 are Arranged in parallel.

次に、把持プレート50を把持し屋根ユニット13側へ移動させると、把持プレート50は羽根部材22の回転中心側を支点として回転すると共に、把持プレート50のピン54を中心に挿通孔52を介して複数の羽根部材22の自由端側が回転する。   Next, when the gripping plate 50 is gripped and moved to the roof unit 13 side, the gripping plate 50 rotates with the rotation center side of the blade member 22 as a fulcrum, and through the insertion hole 52 around the pin 54 of the gripping plate 50. Thus, the free end sides of the plurality of blade members 22 rotate.

そして、羽根部材22が完全開放された状態では、把持プレート50の規制片60が屋根ユニット13の上弦材16の内面側に係止され移動規制されて、把持プレート50を介して複数の羽根部材22の仮止めされる。   When the blade member 22 is fully opened, the restricting piece 60 of the gripping plate 50 is locked to the inner surface side of the upper chord member 16 of the roof unit 13 and is restricted from moving, and a plurality of blade members are interposed via the gripping plate 50. 22 is temporarily fixed.

本実施形態では、把持プレート50の移動によって、複数の羽根部材22を同時に移動させることができるため、複数の羽根部材22を個々に移動させる場合と比較して作業性が向上し、大変便利である。   In this embodiment, since the plurality of blade members 22 can be moved simultaneously by the movement of the gripping plate 50, the workability is improved compared to the case where the plurality of blade members 22 are individually moved, which is very convenient. is there.

また、把持プレート50の外側に規制片60を設けて、把持プレート50を介して羽根部材22が仮止めできるようにすることで、把持プレート50と羽根部材22を移動規制させる規制部材とを別々に設ける必要が無く、把持手段と規制手段を兼用することができる。このため、把持手段と規制手段を別々に設けた場合と比較して、コストダウンを図ることができる。なお、リンク機構を構成する把持プレート50は羽根部材22を移動させる際に把持することができれば良いため、形状は特にこれに限るものではない。   Further, by providing a regulating piece 60 on the outside of the gripping plate 50 so that the blade member 22 can be temporarily fixed via the gripping plate 50, the gripping plate 50 and the regulating member that restricts the movement of the blade member 22 are separated. Therefore, it is possible to use both the gripping means and the regulating means. For this reason, compared with the case where a holding means and a control means are provided separately, cost reduction can be aimed at. Note that the shape of the gripping plate 50 constituting the link mechanism is not particularly limited as long as it can be gripped when the blade member 22 is moved.
