次に、このように構成する簡易構造物の施工手順について説明する。なお、以下において、垂木1には妻垂木1aを含み、連結具3には妻垂木1a用の連結具3aを含む。まず、図7(a)に示すように、躯体Sの前側の各柱4の立設位置に、基礎穴Hを形成する。この際、躯体Sの基礎が布基礎である場合、地中の基礎が躯体S自体よりも前側に突出しており、基礎穴Hを形成する際の障害物S1となり得る。またそれ以外にも、埋設された種々の配管などが障害物となり得る。そこで、各基礎穴Hは、躯体Sから所定間隔でそれらの障害物を避けた位置に形成される。この実施形態では、柱4が90mm角であって、後側の柱4は、中心が躯体Sの前側面から最低220mm離隔し、そこから簡易構造物の出幅に応じて300mm〜500mmの範囲で前側に移動可能である。また、前側の柱4は、簡易構造物の出幅に応じて躯体Sの前側面からの最大距離が定まり、そこから簡易構造物の出幅に応じて300mm〜500mmの範囲で後側に移動可能である。さらに、前後の柱4とも、左右方向に関して、内側に最大500mm、外側に最大47mmの範囲で移動可能である。 Next, the construction procedure of the simple structure configured in this way will be described. In the following, the rafter 1 includes the wife rafter 1a, and the connector 3 includes the connector 3a for the wife rafter 1a. First, as shown in FIG. 7A, a foundation hole H is formed at an erection position of each pillar 4 on the front side of the skeleton S. At this time, when the foundation of the skeleton S is a cloth foundation, the foundation in the ground protrudes to the front side of the skeleton S itself, and can be an obstacle S1 when forming the foundation hole H. In addition to that, various buried pipes and the like can be obstacles. Therefore, each foundation hole H is formed at a position avoiding those obstacles at predetermined intervals from the skeleton S. In this embodiment, the pillar 4 is 90 mm square, and the center of the rear pillar 4 is at least 220 mm away from the front side surface of the skeleton S, and the range from 300 mm to 500 mm is provided depending on the protruding width of the simple structure. It is possible to move to the front side with. Further, the front pillar 4 has a maximum distance from the front side surface of the skeleton S determined according to the protruding width of the simple structure, and then moves to the rear side within a range of 300 mm to 500 mm according to the protruding width of the simple structure. It is possible. Further, both the front and rear pillars 4 can be moved in a range of a maximum of 500 mm inward and a maximum of 47 mm outward in the left-right direction.
続いて、2本の柱4に桁2を横架して門形に組み、これを2組作って、図7(b)に示すように、それぞれ柱4を前側と後側の左右の基礎穴Hに立て、基礎穴Hにコンクリート又はモルタルを流し込んで固定する。ただし、垂木1の傾斜に合わせて、前側の柱4よりも後側の柱4の方が高くなっている。 Subsequently, the girder 2 is laid horizontally on the two pillars 4 and assembled in a gate shape, and two sets are made, and as shown in FIG. 7 (b), the pillars 4 are used as the front and rear left and right foundations, respectively. Stand in the hole H and pour concrete or mortar into the foundation hole H to fix it. However, the pillar 4 on the rear side is higher than the pillar 4 on the front side in accordance with the inclination of the rafter 1.
続いて、図7(c)に示すように、前後の桁2に垂木1を載置して固定する。垂木1と桁2の連結には、上記のとおり連結具3を用いる。ここで、垂木1は所定の位置に取り付けるものであって、この実施形態では、垂木1の後端に取り付ける後枠5bと、躯体Sの間の間隔が、70mmとなる位置とする。この際、上記のように、柱4の前後位置は地中の障害物によって移動するので、垂木1に対する桁2の取付位置はその都度変化するものであり、柱4の前後位置が確定することで、垂木1に対する桁2の取付位置が定まる。よって、垂木1の固定に際しては、まず、地上において、連結具3の係合部32を垂木1の被係合部11に係合させ、連結具3を垂木1の端部から上記のように定まった桁2の取付位置まで摺動させて、連結具3の垂木固定部33を下側から垂木1にネジ止めする。こうして各垂木1に前後2つずつ連結具3を取り付ける。次に、垂木1を持ち上げて、屋根の設置位置である高所において、前後の桁2の上に載置する。既に連結具3の位置合わせをしてあり、前後の連結具3の位置がそれぞれ前後の桁2と一致するので、連結具3の桁固定部34を上側から桁2にネジ止めする。 Subsequently, as shown in FIG. 7C, the rafters 1 are placed and fixed on the front and rear girders 2. As described above, the connecting tool 3 is used to connect the rafter 1 and the girder 2. Here, the rafter 1 is attached at a predetermined position, and in this embodiment, the distance between the rear frame 5b attached to the rear end of the rafter 1 and the skeleton S is 70 mm. At this time, as described above, since the front-rear position of the pillar 4 is moved by an obstacle in the ground, the attachment position of the girder 2 with respect to the rafter 1 changes each time, and the front-rear position of the pillar 4 is fixed. Then, the mounting position of the girder 2 with respect to the rafter 1 is determined. Therefore, when fixing the rafter 1, first, on the ground, the engaging portion 32 of the connecting tool 3 is engaged with the engaged portion 11 of the rafter 1, and the connecting tool 3 is engaged from the end portion of the rafter 1 as described above. The rafter fixing portion 33 of the connecting tool 3 is screwed to the rafter 1 from the lower side by sliding it to the fixed mounting position of the girder 2. In this way, two connecting tools 3 are attached to each rafter 1. Next, the rafter 1 is lifted and placed on the front and rear girders 2 at a high place where the roof is installed. Since the positions of the connecting tools 3 have already been aligned and the positions of the front and rear connecting tools 3 coincide with the front and rear girders 2, the girder fixing portion 34 of the connecting tools 3 is screwed to the girder 2 from the upper side.
その後、垂木1の前後端にそれぞれ前枠5aと後枠5bを取り付けるとともに、前後方向中間部に中桟6を取り付ける。なお、後枠5bには、予めクッション材9を取り付ける。続いて、垂木1の間にパネル材7を取り付けてパネル押さえ具71で固定し、さらに垂木1に垂木カバー8を取り付けて、簡易構造物が完成する。 After that, the front frame 5a and the rear frame 5b are attached to the front and rear ends of the rafter 1, and the middle rail 6 is attached to the middle portion in the front-rear direction. A cushion material 9 is attached to the rear frame 5b in advance. Subsequently, the panel material 7 is attached between the rafters 1 and fixed by the panel retainer 71, and the rafter cover 8 is further attached to the rafters 1 to complete the simple structure.
このように構成した本発明の簡易構造物によれば、垂木1と桁2を連結する際に、予め連結具3を垂木1に固定できるので、作業者は、連結具3を取り付けた垂木1とネジのみを持って高所に上がり、連結具3を桁2にネジ止めすればよく、施工性が良好である。連結具3は予め垂木1の所定の位置に付いており、これだけで垂木1を所定の位置に取り付けられるので、高所で垂木1の位置合わせを行う必要がない。また、連結具3を垂木1に固定する際、連結具3が垂木1に対して摺動自在なので、柱4の取付位置に応じた位置合わせが容易である。 According to the simple structure of the present invention configured in this way, when connecting the rafter 1 and the girder 2, the connecting tool 3 can be fixed to the rafter 1 in advance, so that the operator can fix the rafter 1 to which the connecting tool 3 is attached. It suffices to go up to a high place with only the screw and the fitting 3 and screw it to the girder 2, and the workability is good. Since the connecting tool 3 is attached to the rafter 1 at a predetermined position in advance and the rafter 1 can be attached to the predetermined position only by this, it is not necessary to align the rafter 1 at a high place. Further, when the connecting tool 3 is fixed to the rafter 1, since the connecting tool 3 is slidable with respect to the rafter 1, it is easy to align the connecting tool 3 according to the mounting position of the pillar 4.
本発明は、上記の実施形態に限定されない。たとえば、連結具の形状は、垂木に摺動自在かつ予め固定可能で、さらに桁にも固定可能なものであれば、どのようなものであってもよい。また、この簡易構造物は、前側のみに柱を有し、屋根の後端部を躯体の壁に接合するものであってもよいし、躯体に近接せず独立して設置するものであってもよい。 The present invention is not limited to the above embodiments. For example, the shape of the connector may be any shape as long as it is slidable to the rafters, can be fixed in advance, and can be fixed to the girder. Further, this simple structure may have columns only on the front side and the rear end of the roof may be joined to the wall of the skeleton, or it may be installed independently without being close to the skeleton. May be good.
