Description

【０００１】
【発明の属する技術分野】
本発明は、屋外の土木建築作業現場や植物栽培施設、スポーツ施設、造船用のドック等の屋外施設において、必要な時に雨除け用に、拡開させて使用する簡易な構造の仮設膜式開閉屋根構造に関する。
【０００２】
【従来の技術】
従来、屋外施設における雨除けや日除けのために使用する簡易な屋根構造には、金属製の骨組み材料や吊り材料を使用し、これに支持させて天幕を張設するようにした構造のものがあり、これは必要な時に骨組み材料を組み立て、その上に天幕を張るものであり、不使用時には天幕を外し、骨組み材料を解体して保管している。
【０００３】
また、開閉式の屋根構造としては、ドーム型その他の屋根を複数分割した複数の屋根構造体を使用し、建物の側壁上端部に設置したレール上をそれぞれ移動自在とし、分割された各屋根構造体が上下多重配置に重なるようにして一方側に格納することにより、屋根が開放されるようにした構造のものがある。
【０００４】
更に、開閉式屋根構造として天幕を使用したものもあり、この種の開閉屋根構造は、建物の両側壁上に設置した一対のレール上に、それぞれ自立して平行移動自在に掛け渡した梁材を多数設置し、該梁材に天幕を固定しておき、各梁材を互いに離反させる方向に平行移動させることにより天幕が拡開されて張設され、各梁材を互いに接近させる方向に移動させて片側に寄せることにより天幕が一方側に寄せられて畳まれ、屋根が開放されるようにした構造のものがある。
【０００５】
【発明が解決しようとする課題】
前述した従来の必要な時に骨組みを組み立てて天幕を張る構造のものは、手作業で骨組みの組み立てや解体ができる程度の大きさである場合には、簡単に設置や解体が可能であるが、数百平方メートルといったような大型のものでは、骨組みや天幕が大きくなり、設置や解体に大型の重機や多数の作業者が必要になり、短時間毎に開閉が必要な屋根構造には不向きである。
また従来の、屋根を複数分割した複数の屋根構造体を使用し、これを水平方向にスライドさせて開閉を行う構造のものは、恒久的な建築物の開閉屋根構造としては使用価値があるが、一定期間例えば数ヶ月乃至数年の使用の後解体し、別の場所で再度使用するような場合には、コスト的に不利であり、適しない。
【０００６】
更に従来の、天幕を複数の梁材に支持させて移動させるようにした構造の物の場合は、簡易な構造であるが、梁材自体の耐曲げ強度によってレール間に自立して掛け渡されるものであるため、梁断面が大きく、長スパンになればなる程、梁断面が大型化し、屋根開放時の屋根材収納スペースを広く要し、その分開放広さを制約し、しかも設置及び解体が困難になるという問題があった。
【０００７】
本発明は、上述のような従来の問題に鑑み、開閉が容易に行えるとともに、屋根開放時の屋根材収納スペースが小さく、開放率が大きく取れ、設置や解体が超スパンものでも比較的容易に低コストで行え、数ヶ月程度の短期間使用後の解体、移設であってもコスト的に不利とならない仮設膜式開閉屋根構造の提供を目的としてなされたものである。
【０００８】
【課題を解決するための手段】
上述の如き従来の問題を解決し、所期の目的を達成するための本発明の特徴は、屋根用膜材と、該屋根用膜材に対して一定間隔毎に平行配置に固定された多数の膜材支持用引張線材と、固定構造部に対してそれぞれ支持される互いに並行配置の一対のレールと、前記各レールに対して長さ方向に移動自在に支持された多数のスライダーと、前記両レールの内の少なくとも一方側を他方側に対して接近離反する方向に平行移動させるレール間隔調整機構とを備え、前記膜材支持用引張線材毎にその一端側を一方側の前記両レールに支持させたスライダーに、他端側を他方側の前記レールに支持させたスライダーにそれぞれ固定し、前記レール間隔調整機構により前記膜支持用引張線材をたるませた状態と緊張させた状態とに調整可能にしたことにある。
【０００９】
尚、両レールとしてＣ型鋼材を使用し、該Ｃ型鋼材の開口溝部を互いに対向させて両レールを配置させ、該Ｃ型鋼材内を転動するローラーと、該ローラーを支持させたフレームをもってスライダーを構成させることが好ましく、レール間隔調整機構は、固定配置の支持部に対して回転自在で移動不能に支持させたネジ軸と、該ネジ軸を回転動作させる駆動手段と、前記ネジ軸に対して螺合した雌ネジを一体に有する複数の移動駒と、該移動駒を固定したレール支持部材とを有し、該レール支持部材にレールを固定し、前記駆動手段によりネジ軸を回転させることによって一方側のレールを移動させるようにすることが好ましい。
【００１０】
【発明の実施の形態】
次に本発明の実施の形態を図面について説明する。
【００１１】
図１は、本発明に係る仮設膜式開閉屋根構造の概略構成を示しており、図において符号１ａ，１ｂは、互いに並行配置のコンクリート壁からなる固定構造部であり、この固定構造部１ａ，１ｂ間に、多数の膜材支持用引張線材２，２……をもって支持させた屋根用膜材３を拡開させることにより屋根Ａが張設され、上記引張線材２，２を片側に寄せる方向に移動させることにより屋根用膜材３が畳まれて屋根Ａが開放されるようになっている。
【００１２】
固定構造部１ａ，１ｂの頂部内側には互いに平行配置にレール４，５が設置されている。この両レール４，５はＣ型チャンネル状をした型鋼材をもって構成され、Ｃ型の開口溝状部６を互いに対向させて並行配置に設置されている。
【００１３】
一方のレール４は一方の固定構造部１ａに固定されているのに対し、他方のレール５は他方の固定構造部１ｂに対して幅方向、即ち一方のレール１ａ接近離反する方向に往復移動自在に支持されている。即ち、レール５は、図２に示すように固定構造部１ｂに対して複数の間隔調整機構７を介して支持されている。
【００１４】
この間隔調整機構７は、図３に示すように、固定構造部１ｂから突設した支持腕７１、該支持腕７１上に固定したガイド軸７２，及び該支持腕７１上に回転自在に軸受け７３，７３を介し、前記レール４の向きと直行する向きに支持させたネジ軸７４、該ネジ軸７４に螺合した一対の雌ネジ７５，７５を底部に固定した移動台７６及び前記ネジ軸７４に対してギヤ機構７７を介して回転駆動を与える駆動手段である電動モータ７８をもって構成され、前記移動台７６にレール５を固定している。
【００１５】
従って、モータ７８を正又は逆転させることにより、ネジ軸７４が回転され、これに底部の雌ネジ７５が螺合している移動台７６が移動され、これによって移動台７６に支持されているレール５が一方のレール４に対して接近離反する方向に平行移動し、両レール４，５間の間隔が調整されるようになっている。
【００１６】
各レール４，５には、図４に示すように引張線材の数に合わせた数のスライダー８，８……が長手方向に移動自在に挿入されている。このスライダー８はフレーム８１と、該フレーム８１に回転自在に軸支させた４個のローラー８２，８２……とから構成され、各ローラー８２がレール４又は５の開口溝状部６を構成している両側縁部６１の内面を転動するように構成され、フレーム８１の中央部分に引張線材連結部８３が突設され、これが溝状開口部６から突出されている。尚、レール４，５の端部開口部は閉鎖され、スライダー８が抜け出ないようにされている。
【００１７】
このように構成される各スライダー８が、前述した各引張線材２の両端にそれぞれ１個当て備えられ、引張線材２の一端側が一方のレール４内に挿入したスライダー８の引張線材連結部８３に固定され、他端側が他方のレール５内に挿入したスライダー８の引張線材連結部８３に固定されている。
【００１８】
そして、前述した間隔調整機構７によってレール５をレール４から遠ざかる方向に平行移動させることにより引張線材２に張力が付加されて真っ直ぐに近い状態に張設されて、スライダー８が容易には移動しない状態となり、膜材３が雨で撓んでも水勾配が確保されるようになり、逆にレール５をレール４に近づける方向に平行移動させることにより、引張線材２がたるんだ状態となり、スライダー８を容易に移動させることができる状態となるようにしている。
【００１９】
このように構成される仮設膜式開閉屋根構造は、レール５を移動させ、スライダー８が容易に移動できる状態に引張線材２をたるませた状態で、屋根用膜材３が広がる方向に各スライダー８を移動させ、所望の広がり状態とした後、レール５引張材緊張側に移動させて引張力を付加させ、屋根Ａの拡開状態を維持させる。
【００２０】
また、屋根Ａを畳む際には、引張線材２がたるむ方向にレール５を移動させ、各スライダー８をレール４，５の一端側に寄せることにより、屋根用膜材３は、隣り合う引張線材２，２の接近によって自重によってたる片側に寄せられた状態で畳まれる。
【００２１】
尚、一方のレール４は他方のレール５より低い位置に設置され、屋根用膜材３を拡開させて引張線材２を緊張させた際に、雨水が流下するための勾配をもたせている。また、低い側のレール下には雨樋９を設置し、雨水を集めて流すようにしている。
【００２２】
尚、上述した実施例では、固定構造部が平行なコンクリート壁体である場合を示しているが、この他、両レール４，５を支持できるように互いに並行配置に設置した固定梁であってもよく、また、両レール４，５を支持できるように２列配置に立設した支柱であってもよい。
【００２３】
【発明の効果】
上述のように、本発明に係る仮設膜式開閉屋根構造は、屋根用膜材と、該屋根用膜材に対して一定間隔毎に平行配置に固定された多数の膜材支持用引張線材と、固定構造部に対してそれぞれ支持される互いに並行配置の一対のレールと、前記各レールに対して長さ方向に移動自在に支持された多数のスライダーと、前記両レールの内の少なくとも一方側を他方側に対して接近離反する方向に平行移動させるレール間隔調整機構とを備え、前記膜材支持用引張線材毎にその一端側を一方側の前記両レールに支持させたスライダーに、他端側を他方側の前記レールに支持させたスライダーにそれぞれ固定し、前記レール間隔調整機構により前記膜支持用引張線材をたるませた状態と緊張させた状態とに調整可能にしたことにより、従来の天幕を使用した開閉屋根構造のように屋根用膜材を支持させるための自立した構造の梁が不要になり、屋根が軽量化され、設置及び解体が容易に行え、製造及び使用コストも低廉となる。
【００２４】
また、屋根用膜材が線材によって支持されるため、屋根を開放する方向に折り畳んだ際に、場所を取らず、屋根の開放率が大きい。
【００２５】
また、本発明は、両レールとしてＣ型鋼材を使用し、該Ｃ型鋼材の開口溝部を互いに対向させて両レールを配置させ、該Ｃ型鋼材内を転動するローラーと、該ローラーを支持させたフレームをもってスライダーを構成させることにより、スライダーがレールから外れる事がなくなり、風によって飛ばされる恐れが少ない。
更に、本発明では、レール間隔調整機構は、固定配置の支持部に対して回転自在で移動不能に支持させたネジ軸と、該ネジ軸を回転動作させる駆動手段と、前記ネジ軸に対して螺合した雌ネジを一体に有する複数の移動駒と、該移動駒を固定したレール支持部材とを有し、該レール支持部材にレールを固定し、前記駆動手段によりネジ軸を回転させることによって一方側のレールを移動させるようにしたことにより、屋根の使用時即ち屋根用膜材の拡開時には容易に移動することがなく、移動操作時には容易に移動させることができ、拡開時の安定性が良く、移動時の操作性が良い。

[0002]
[Prior art]
Conventionally, a simple roof structure used for rain protection and sun protection in outdoor facilities has a structure in which a awning is stretched using a metal frame material or suspension material supported by this. Yes, this is to assemble the frame material when necessary, and to put a tent on it. When not in use, the awning is removed and the frame material is disassembled and stored.
[0003]
In addition, as the openable roof structure, a plurality of roof structures obtained by dividing a plurality of roofs, such as dome type, are used, and each of the divided roof structures can be moved on the rail installed at the upper end of the side wall of the building. There is a structure in which the roof is opened by storing the body on one side so as to overlap the upper and lower multiple arrangements.
[0004]
In addition, there is also an openable roof structure that uses a awning, and this type of openable roof structure is a beam of material that spans a pair of rails installed on both side walls of the building so that they can stand independently and translate freely. The awning is expanded and stretched by moving the beam members in parallel to move away from each other, and moving the beam members in a direction approaching each other. There is a structure in which the roof is opened by bringing the awning to one side and folding it by bringing it to one side.
[0005]
[Problems to be solved by the invention]
The conventional structure that assembles the skeleton and stretches the tent when necessary can be easily installed and disassembled if it is large enough to be assembled and disassembled manually. Large ones such as hundreds of square meters have a large skeleton and awning, require large heavy machinery and many workers for installation and dismantling, and are not suitable for roof structures that need to be opened and closed every short time. .
In addition, a conventional structure that uses a plurality of roof structures obtained by dividing a roof into a plurality of roofs and slides them horizontally to open and close is worth using as a permanent building open / close roof structure. In the case of dismantling after use for a certain period of time, for example, several months to several years, and reusing at another place, it is disadvantageous in terms of cost and is not suitable.
[0006]
Furthermore, in the case of a conventional structure in which the awning is supported by a plurality of beam members and moved, it is a simple structure, but it is stretched independently between the rails by the bending strength of the beam member itself. Therefore, the larger the beam cross-section and the longer the span, the larger the beam cross-section, requiring a larger space for storing the roofing material when the roof is open, and constraining the open space, and installing and dismantling There was a problem that became difficult.
[0007]
In view of the conventional problems as described above, the present invention can be easily opened and closed, has a small roof material storage space when the roof is opened, has a large opening rate, and is relatively easy even when installation and dismantling are super span. The purpose is to provide a temporary membrane-type open / close roof structure that can be performed at low cost, and that is not disadvantageous in terms of cost even if it is dismantled and relocated after a short period of use for several months.
[0008]
[Means for Solving the Problems]
The features of the present invention for solving the conventional problems as described above and achieving the intended purpose are a roofing membrane material and a number of them fixed in parallel with the roofing membrane material at regular intervals. The membrane material supporting tensile wire, a pair of rails arranged in parallel to each other supported by the fixed structure portion, a number of sliders supported to be movable in the length direction with respect to each rail, A rail interval adjusting mechanism that translates at least one side of both rails in a direction approaching and separating from the other side, and one end side of each of the film material supporting tensile wires is used as one rail on both sides. The other end side is fixed to the slider supported by the rail on the other side of the supported slider, and the film support tension wire is adjusted to be slack and tensioned by the rail interval adjustment mechanism. What we made possible A.
[0009]
In addition, C-type steel materials are used as both rails, both rails are arranged with the opening groove portions of the C-type steel materials facing each other, a roller that rolls in the C-type steel material, and a frame that supports the rollers. It is preferable that the slider is configured, and the rail interval adjustment mechanism includes a screw shaft that is rotatably supported with respect to a fixedly arranged support portion, and a drive unit that rotates the screw shaft. A plurality of moving pieces integrally having female screws screwed to each other, and a rail support member to which the moving pieces are fixed, the rail is fixed to the rail support member, and the screw shaft is rotated by the driving means. It is preferable to move the rail on one side.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0011]
FIG. 1 shows a schematic configuration of a temporary membrane-type open / close roof structure according to the present invention. In the figure, reference numerals 1a and 1b denote fixed structure parts composed of concrete walls arranged in parallel to each other. The roof A is stretched by expanding the roof membrane material 3 supported by a large number of membrane material supporting tensile wires 2, 2... Between 1b, and the tensile wires 2, 2 are moved to one side. The roof membrane material 3 is folded so that the roof A is opened.
[0012]
Rails 4 and 5 are installed in parallel to each other inside the top portions of the fixed structure portions 1a and 1b. Both the rails 4 and 5 are made of a steel material having a C-shaped channel shape, and are arranged in parallel with the C-shaped opening groove portions 6 facing each other.
[0013]
One rail 4 is fixed to one fixed structure portion 1a, while the other rail 5 is reciprocally movable in the width direction relative to the other fixed structure portion 1b, that is, in the direction in which one rail 1a approaches and separates. It is supported by. That is, the rail 5 is supported with respect to the fixed structure portion 1b via a plurality of interval adjusting mechanisms 7 as shown in FIG.
[0014]
As shown in FIG. 3, the distance adjusting mechanism 7 includes a support arm 71 projecting from the fixed structure portion 1 b, a guide shaft 72 fixed on the support arm 71, and a bearing 73 that is rotatable on the support arm 71. , 73 via a screw shaft 74 supported in a direction perpendicular to the direction of the rail 4, a pair of female screws 75, 75 screwed to the screw shaft 74 fixed to the bottom, and the screw shaft 74 An electric motor 78 which is a driving means for providing rotational driving via a gear mechanism 77, and the rail 5 is fixed to the moving table 76.
[0015]
Accordingly, by rotating the motor 78 forward or backward, the screw shaft 74 is rotated, and the moving table 76 with the female screw 75 at the bottom is screwed to the moving shaft 76, thereby moving the rail supported by the moving table 76. 5 moves in parallel in a direction approaching and separating from one rail 4 so that the distance between the rails 4 and 5 is adjusted.
[0016]
