Description

この発明は、工事用シートの折り畳み方法およびこの折り畳み方法で折り畳まれた工事用シートに関するものである。 The present invention relates to a method for folding a construction sheet and a construction sheet folded by this folding method.

ブルーシートなどの工事用シートを折り畳む場合、工事用シートの中央で折り返して端同士を重ね合わせて、重ね合わせたものの中央で折り返して端同士を重ね合わせることを繰り返して、まず一方を折り畳む。こうして得られる長尺体を、その長手方向の中央で折り返して端同士を重ね合わせて、重ね合わせたものの中央で折り返して端同士を重ね合わせることを繰り返して、コンパクトに折り畳まれている。そして、工事用シートは、折り畳んだ状態で流通し、現場に提供されている。 When folding a construction sheet such as a blue sheet, fold it back at the center of the construction sheet and stack the ends together, then fold back at the center of the stacked product and stack the ends together, and then fold one side first. The long body thus obtained is folded back at the center in the longitudinal direction, the ends are overlapped with each other, and the folded back is repeated at the center of the overlapped product so that the ends are overlapped with each other to be compactly folded. The construction sheet is distributed in the folded state and provided to the site.

例えば、枠組壁工法は、基礎を構築した後に１階床を施工してから１階外壁および２階を組み立て、最後に屋根を取り付ける順序で建物を作っている。屋根を取り付けられていない施工中の現場で雨が降った場合、１階や２階の床面が濡れてしまうことを回避するため、仮に屋根になるもので覆うことが行われている(例えば、特許文献１および特許文献２参照)。 For example, in the framed wall construction method, after constructing the foundation, the first floor is constructed, then the first floor outer wall and the second floor are assembled, and finally the roof is attached to make the building. If it rains on a construction site where the roof is not attached, it is temporarily covered with something that will become a roof in order to avoid getting the floors of the first and second floors wet (for example, , Patent Document 1 and Patent Document 2).

次に、本発明に係る工事用シートの折り畳み方法および工事用シートにつき、好適な実施例を挙げて、添付図面を参照して以下に説明する。 Next, a method for folding a construction sheet and a construction sheet according to the present invention will be described below with reference to the accompanying drawings with reference to preferred embodiments.

図２に示すように、実施例に係る工事用シート１０は、１枚に広げた展開状態において正方形であり、４辺の縁部のそれぞれに、複数のハトメ１２が所定間隔で設けられている所謂ブルーシートである。工事用シート１０において、横方向中央を縦方向へ通って、展開したときの基準となる仮想ラインを基準中央線(中央線)Ｃといい、基準中央線Ｃと平行する端を横端１６といい、基準中央線Ｃと交差する端を縦端１８という。 As shown in FIG. 2, the construction sheet 10 according to the embodiment has a square shape when unfolded into one sheet, and a plurality of eyelets 12 are provided at predetermined intervals on each of four edge portions. It is a so-called blue sheet. In the construction sheet 10, a virtual line that passes through the horizontal center in the vertical direction and serves as a reference is referred to as a reference center line (center line) C, and an end parallel to the reference center line C is referred to as a horizontal end 16. The end intersecting with the reference center line C is called the vertical end 18.

図１に示すように、工事用シート１０は、矩形状に折り畳まれた折り畳み状態が荷姿であり、この折り畳み状態で搬送されて、工事現場などの使用場所に提供される。折り畳み状態にある工事用シート１０は、該工事用シート１０の基準中央線Ｃ(図２参照)で折り返して形成された中央折り目(折り目)１４と、中央折り目１４を挟んで配置されて、展開状態にある該工事用シート１０において平行する一対の横端(端)１６,１６とを備えている。折り畳み状態の工事用シート１０は、中央折り目１４および該中央折り目１４を挟む一対の横端１６,１６が、折り畳まれた工事用シート１０における同じ側面に露出すると共に、一対の横端１６,１６よりも中央折り目１４が出っ張るように配置されている。また、折り畳み状態の工事用シート１０は、横端１６を含む縁部に設けられたハトメ１２が露出している。 As shown in FIG. 1, the construction sheet 10 is in a package shape when folded in a rectangular shape, and is transported in this folded state to be provided to a use place such as a construction site. The construction sheet 10 in the folded state is arranged with the central fold (crease) 14 formed by folding back at the reference center line C (see FIG. 2) of the construction sheet 10 and the central crease 14 sandwiched between the sheets. The construction sheet 10 in the state is provided with a pair of parallel lateral ends (ends) 16. In the construction sheet 10 in the folded state, the central fold 14 and the pair of lateral ends 16 and 16 sandwiching the central fold 14 are exposed on the same side surface of the folded construction sheet 10, and the pair of lateral ends 16 and 16 are provided. It is arranged so that the central fold line 14 projects more than the center fold line. Further, in the folded construction sheet 10, the eyelets 12 provided on the edge portion including the lateral end 16 are exposed.

次に、折り畳み状態において、中央折り目１４が一対の横端１６,１６の間から出っ張って配置される工事用シート１０の折り畳み方法について、図３〜図１１を参照して説明する。 Next, a method of folding the construction sheet 10 in which the central fold 14 is arranged so as to project from between the pair of lateral ends 16 in the folded state will be described with reference to FIGS. 3 to 11.

（第１ステップ）
図３に示すように、第１ステップの第１段階において、矩形状の工事用シート１０における片側半分を、該片側半分の横端１６が該工事用シート１０の基準中央線Ｃを越えないようにずらして折り返す。図４に示すように、第１ステップの第２段階において、第１段階で形成された片側半分の横折り目(折り目)２０が該片側半分の横端１６を越えないようにずらして、工事用シート１０における片側半分を折り返す。第２段階では、工事用シート１０の基準中央線Ｃとずらして配置される横端１６を含む縁部に設けられたハトメ１２が露出するように折り畳む。更に、図５に示すように、第１ステップの第３段階において、工事用シート１０における片側半分を、折り返して形成される横折り目(折り目)２０が該片側半分の横端１６を越えないようにずらして折り畳む。実施例の第３段階では、工事用シート１０を巻くように折り返して、第３段階で形成される内側の横折り目２０を、第２段階で横端１６とずらして配置された横折り目２０と揃うように配置している。このように、第２段階および第３段階では、工事用シート１０における片側半分を折り返す際に、第１段階で基準中央線Ｃに沿わせて配置された横端１６を含む縁部に設けられたハトメ１２に重ならないように折り畳まれる。なお、第１ステップでは、工事用シート１０の折り返した片側半分は、縦端１８同士を揃えて重ねている。 (First step)
As shown in FIG. 3, in the first stage of the first step, one side half of the rectangular construction sheet 10 is prevented from having a lateral end 16 of the one side half exceeding the reference center line C of the construction sheet 10. Shift and turn back. As shown in FIG. 4, in the second step of the first step, the horizontal folds (folds) 20 of the half on one side formed in the first step are shifted so as not to cross the lateral end 16 of the half on one side, and the work for construction is performed. Fold one half of the sheet 10 back. In the second step, the construction sheet 10 is folded so that the eyelets 12 provided at the edge portion including the lateral end 16 that is arranged offset from the reference center line C are exposed. Further, as shown in FIG. 5, in the third step of the first step, the lateral fold (crease) 20 formed by folding back one half of the construction sheet 10 does not exceed the lateral end 16 of the one half. Shift and fold. In the third step of the embodiment, the construction sheet 10 is folded back so that the inner lateral folds 20 formed in the third step are the lateral folds 20 displaced from the lateral ends 16 in the second step. They are arranged so that they are aligned. Thus, in the second step and the third step, when one half of the construction sheet 10 is folded back, it is provided at the edge portion including the lateral end 16 arranged along the reference center line C in the first step. The eyelets 12 are folded so that they do not overlap. In the first step, the folded back half of the construction sheet 10 has the vertical ends 18 aligned with each other.

（第２ステップ）
図６に示すように、第２ステップでは、第１ステップで折り畳んだ片側半分が下になるように工事用シート１０の基準中央線Ｃで折り返す。次に、図７および図８に示すように、工事用シート１０における残りの片側半分を第１ステップと同じように折り畳む。これにより、図９に示すように、工事用シート１０が横方向に折り畳まれて、縦方向に長い長尺体２２になる。このとき、長尺体２２は、基準中央線Ｃで折り曲げて形成された中央折り目１４を上下に挟んで一対の横端１６,１６が中央折り目１４からずらして配置されて、各横端１６からずらして横折り目２０が配置されている。また、長尺体２２は、中央折り目１４および一対の横端１６,１６が該長尺体２２における同じ側に配置される。更に、長尺体２２は、中央折り目１４が一対の横端１６,１６よりも出っ張ると共に、一対の横端１６,１６が横折り目２０よりも出っ張っている。 (Second step)
As shown in FIG. 6, in the second step, the work sheet 10 is folded back along the reference center line C so that the half on one side folded in the first step is facing down. Next, as shown in FIGS. 7 and 8, the remaining half on one side of the construction sheet 10 is folded in the same manner as in the first step. As a result, as shown in FIG. 9, the construction sheet 10 is folded in the lateral direction to form the elongated body 22 that is long in the longitudinal direction. At this time, the elongated body 22 is arranged such that the pair of lateral ends 16 and 16 are vertically offset from each other with the central fold line 14 formed by being bent along the reference center line C sandwiched therebetween. Lateral folds 20 are arranged in a staggered manner. Further, in the elongated body 22, the central fold line 14 and the pair of lateral ends 16, 16 are arranged on the same side of the elongated body 22. Further, in the elongated body 22, the central fold line 14 projects beyond the pair of lateral ends 16 and 16, and the pair of lateral ends 16 and 16 projects beyond the lateral fold line 20.

（第３ステップ）
図１０に示すように、第３ステップの第１段階において、前記第１ステップおよび前記第２ステップを経て得られた長尺体２２を、その長手方向の縦中央線(中央線)２４を挟む略半分ずつをそれぞれ折り畳む。実施例の長尺体２２は、略半分を内側から山折り・谷折りを繰り返す所謂蛇腹折りで折り畳んでおり、略半分の折り畳み部分同士の間隔をあけている。図１１に示すように、第３ステップの第２段階において、第１段階で折り畳んだ半分同士を重ねるように、縦中央線(中央線)２４で折り返すことで、工事用シート１０は前述した折り畳み状態になる。 (Third step)
As shown in FIG. 10, in the first step of the third step, the elongated body 22 obtained through the first step and the second step is sandwiched by the longitudinal center line (center line) 24 in the longitudinal direction. Fold approximately half each. In the elongated body 22 of the embodiment, approximately half is folded from the inside by so-called bellows folding in which mountain folds and valley folds are repeated, and approximately half of the folded portions are spaced from each other. As shown in FIG. 11, in the second step of the third step, the construction sheet 10 is folded by the vertical center line (center line) 24 so that the halves folded in the first step are overlapped with each other. It becomes a state.

次に、前述した折り畳み状態にある工事用シート１０の使用方法について説明する。第３ステップの第２段階で折った縦中央線２４を、工事用シート１０を展開したときの中心としたい位置に置く。次に、蛇腹折りにした長尺体２２の半分ずつを、縦中央線２４を基準としてそれぞれ展開する。長尺体２２の一側面に出っ張っている中央折り目１４を、工事用シート１０を展開したときの中心としたい位置に合わせる。長尺体２２における同じ一側面に配置されている一対の横端１６,１６を持って、中央折り目１４を基準として、第１ステップおよび第２ステップで折り畳んだ部分をそれぞれ展開する。これにより、展開状態にある工事用シート１０を、配置したい位置に中心を合わせて簡単に敷設することができる。 Next, a method of using the construction sheet 10 in the folded state described above will be described. The vertical center line 24 folded in the second stage of the third step is placed at a position desired to be the center when the construction sheet 10 is unfolded. Next, the halves of the elongated body 22 folded in a bellows are unfolded with respect to the vertical center line 24. The central fold line 14 projecting from one side surface of the elongated body 22 is aligned with a desired position as a center when the construction sheet 10 is unfolded. With the pair of lateral ends 16, 16 arranged on the same one side surface of the elongated body 22, the parts folded in the first step and the second step are unfolded with the central fold line 14 as a reference. As a result, the construction sheet 10 in the unfolded state can be easily laid with its center aligned with the desired position.

前述した折り畳み状態にある工事用シート１０は、展開状態になったときに中心となる位置が判り易いので、位置合わせを簡単に行うことができる。すなわち、建築中の建物に対して屋根代わりに敷設するときなど、足場が不安定な状態であっても、位置合わせを簡単にでき、工事用シート１０を展開した後に位置調節する手間を省くことができる。また、基準中央線Ｃを折った中央折り目１４と対となる横端１６,１６が同じ側面に位置しているので判り易く、中央折り目１４が出っ張っているので、基準中央線Ｃを簡単に判別することができる。しかも、一対の横端１６,１６も他の横折り目２０より出っ張って露出しているので、横端１６を簡単に掴むことができる。しかも、横端１６に沿って設けられたハトメ１２も、他の横折り目２０よりずれて露出しているので、ハトメ１２へ紐を結びつけたりするなどの作業も行い易い。このように、前述した折り畳み状態にある工事用シート１０は、使い勝手に非常に優れている。 Since the center position of the construction sheet 10 in the folded state described above is easily understood when it is in the unfolded state, the alignment can be easily performed. That is, even when the scaffolding is in an unstable state such as when laying a building under construction as a roof, it is possible to easily align the position and save the labor of adjusting the position after the construction sheet 10 is deployed You can In addition, since the lateral edges 16 and 16 that form a pair with the central fold line 14 obtained by folding the reference center line C are located on the same side surface, it is easy to understand, and since the central fold line 14 is protruding, the reference center line C can be easily identified. can do. Moreover, since the pair of lateral ends 16 and 16 also protrude from the other lateral fold line 20 and are exposed, the lateral end 16 can be easily grasped. In addition, since the eyelets 12 provided along the lateral end 16 are also displaced and exposed from the other lateral folds 20, it is easy to perform work such as tying a string to the eyelets 12. As described above, the construction sheet 10 in the folded state described above is very easy to use.
