Description

本発明は、トラス構造体を用いた屋根の端部を建物の躯体（外壁を含む）に固定して設置する簡易建物に関する。   The present invention relates to a simple building in which an end of a roof using a truss structure is fixed and installed on a building frame (including an outer wall).

玄関前や庭などに設置される簡易建物の一形態として、屋根の一方側を支柱で支持し、屋根の他方側端部を建物の躯体に固定するものがある。このような簡易建物の屋根では、特許文献１の図１，２に記載されているように、屋根パネル１３を支持する垂木３の躯体側端部を、躯体に固定した垂木掛け２に掛けてネジ４で直接固定したり、特許文献１の図３，４に記載されているように、ブラケット５を介して垂木掛け２に固定したりしている。
このような簡易建物の屋根に、特許文献２に開示されているような、上下の弦材と水平材と斜材とからなるトラス構造体を用い、且つその上弦材及び下弦材を躯体と交差する方向に配置しようとすると、その固定が困難であり、また、その固定手段によっては、弦材の端部にだけ荷重が集中し、破損したりするおそれがあり、屋根の強度が保持できない。また屋根を施工する際に、トラス構造体を梁の上で組立てたり、屋根の躯体側を作業者が支持していなければならないのでは、屋根の施工が容易に行えない。
特開２００３−２２７１７６号公報 特開２００６−１５２７５４号公報 As one form of a simple building installed in front of the entrance or in the garden, there is one in which one side of the roof is supported by a column and the other end of the roof is fixed to the building frame. In the roof of such a simple building, as described in FIGS. 1 and 2 of Patent Document 1, the end of the rafter 3 supporting the roof panel 13 is hung on the rafter 2 fixed to the rafter. They are fixed directly with screws 4 or fixed to the rafter 2 via brackets 5 as described in FIGS.
The roof of such a simple building uses a truss structure composed of upper and lower string members, horizontal members and diagonal members as disclosed in Patent Document 2, and intersects the upper and lower chord members with the frame. If it is going to be arranged in the direction, the fixing is difficult, and depending on the fixing means, there is a possibility that the load concentrates only on the end of the chord material and breaks, and the strength of the roof cannot be maintained. Moreover, when constructing a roof, the construction of the roof cannot be easily performed because the truss structure must be assembled on the beam or the worker must support the roof side of the roof.

First, the columns 1 and 1 are erected at a predetermined position on the ground, and the beam 2 is installed between the columns 1 and 1. Next, the housing side frame 5 is fixed to the housing 4 with a coach screw 22. Each of the roof bodies 3a is assembled in advance, and a mounting bracket 6 is attached to each upper chord member 7 of the roof body 3a. Next, the plurality of roof bodies 3 a are sequentially placed on the beam 2. At this time, the frame side frame mounting piece 14 of the mounting bracket 6 is placed on the protruding piece 12 on the lower side of the frame side frame 5, and the frame side of the roof body 3 a is temporarily placed on the frame side frame 5. Next, while adjusting the position of each roof body 3a, the adjacent roof bodies 3a are connected by the connection cover 26, the lower chord material 8 of the roof body 3a is fixed to the beam 2 with the metal fitting 32, and the housing side of the attachment metal fitting 6 is provided. The frame attaching piece 14 is fixed to the projecting piece 12 of the housing side frame 5 with a screw 31. Next, the gutter 18, the gust 19 and the gutter 23 are attached.

本簡易建物は、図１に示すように、屋根体３ａの各上弦材７に取付金具６の上弦材取付片１３が、斜材９と水平材１０ａと上弦材７の接合部１６ａの梁側と躯体側の両方でネジ３０で固定してあるので、上弦材７が補強されて変形を防止でき、尚且つ上弦材７が取付金具６を介して躯体側枠５に強固に固定されるとともに、荷重が斜材９と水平材１０ａに効率良く分散する。また、下弦材８の前後方向中間部を梁２に載置固定したため、トラス構造体を用いた屋根３の強度を保持できる。また、屋根体３ａ，３ａ，…の下弦材８の前後方向中間部を梁２に載置し、上弦材７を取付金具６で躯体側枠５に固定することで、屋根３の施工が容易に行える。さらに、取付金具６を上弦材７に取付けてから取付金具６の躯体側枠取付片１４を躯体側枠５の突出片１２に載置することで、屋根体３ａの躯体側を躯体側枠５に仮置きできるので、屋根体３ａの取付けがより一層容易に行える。さらに本簡易建物は、屋根３がアルミ製部材からなるトラス構造体１１で形成されているので、大型で高強度の屋根を比較的軽量に構成することができ、間口の広い屋根付き空間を戸外に形成できる。屋根３の左右寸法は、使用する屋根体３ａの数を変えることで容易に変更できる。   As shown in FIG. 1, this simple building has an upper chord material mounting piece 13 on each upper chord member 7 of the roof body 3a, and a beam side of a joint portion 16a of the diagonal member 9, the horizontal member 10a and the upper chord member 7. Since the upper chord material 7 is reinforced to prevent deformation, the upper chord material 7 is firmly fixed to the frame side frame 5 via the mounting bracket 6. The load is efficiently distributed to the diagonal member 9 and the horizontal member 10a. Moreover, since the middle part in the front-rear direction of the lower chord member 8 is placed and fixed on the beam 2, the strength of the roof 3 using the truss structure can be maintained. Further, the roof 3a, 3a,... Can be easily constructed by placing the middle portion of the lower chord member 8 in the front-rear direction on the beam 2 and fixing the upper chord member 7 to the frame 5 with the mounting bracket 6. It can be done. Furthermore, after the mounting bracket 6 is mounted on the upper chord member 7, the casing-side frame mounting piece 14 of the mounting bracket 6 is placed on the protruding piece 12 of the casing-side frame 5, so that the casing side of the roof body 3 a is placed on the casing-side frame 5. Therefore, the roof 3a can be attached more easily. Furthermore, in this simple building, the roof 3 is formed of a truss structure 11 made of an aluminum member, so that a large, high-strength roof can be configured to be relatively light, and a roofed space with a wide frontage can be opened outdoors. Can be formed. The left and right dimensions of the roof 3 can be easily changed by changing the number of roof bodies 3a to be used.

本発明は以上に述べた実施形態に限定されない。屋根体を構成する上弦材等の各部材の形状、材質は任意であり、各部材の配置の仕方（部材同士の重なり順、各部材の配置ピッチ等）も適宜変更できる。梁を３本以上の支柱で支持するものであってもよい。また、図７に示すように、屋根の前側だけでなく躯体側にも支柱１と梁２を設けてもよい。本発明は、カーポート、テラスの屋根、通路用シェルターなど、あらゆる簡易建物に適用できる。   The present invention is not limited to the embodiments described above. The shape and material of each member such as the upper chord material constituting the roof body is arbitrary, and the arrangement method of each member (the overlapping order of members, the arrangement pitch of each member, etc.) can be changed as appropriate. The beam may be supported by three or more struts. Moreover, as shown in FIG. 7, you may provide the support | pillar 1 and the beam 2 not only on the front side of a roof but on the housing side. The present invention can be applied to all simple buildings such as carports, terrace roofs, and passage shelters.
