Description

本発明は、農業用温室等に張設されるフィルムシートの取付部材に関する。 The present invention relates to a mounting member for film sheets that are installed in agricultural greenhouses, etc.

従来、農業用温室に張設されるフィルムシートは、フッ素樹脂またはＰＥＴ樹脂を使用した硬質系シートと、塩化ビニールまたはポリフィルムを使用した軟質系シートがあり、軟質系シートでは、一般的に溝型の保持具にシートを挿入してシートの上からバネ材を溝に嵌合してシートを定着する方法が採用されており、他方、硬質系シートでは、一般的に長尺の溝形保持具に両面テープなどで仮止めされたシートを、概略２００ｍｍの等間隔に貫通穴の開いたレール状のシート押え材を、シート上方から溝形の保持具に嵌合し貫通穴毎にビスで挟持して固定している方法が採用されている。 Conventionally, film sheets installed in agricultural greenhouses are divided into two types: hard sheets made of fluororesin or PET resin, and soft sheets made of polyvinyl chloride or polyfilm. With soft sheets, the sheet is generally inserted into a groove-shaped holder and a spring material is fitted into the groove from above to secure the sheet in place. On the other hand, with hard sheets, the sheet is generally temporarily attached to a long groove-shaped holder with double-sided tape or the like, and then a rail-shaped sheet pressing material with through holes at equal intervals of approximately 200 mm is fitted into the groove-shaped holder from above the sheet, and the sheet is fixed by clamping each through hole with a screw.

前記従来のフィルムシートの取付部材としては、例えば、図８に示すような、特開２０１９－６２８２０号公報（特許文献１）記載のものが公知である。前記特許公報１に記載のフィルムシートの取付部材は、透明シートに強風等の強い外力が作用してもシートの定着が解消されず、雨水の侵入を防止でき、シートの破断も防止できるように、上端の開口部３を幅狭に形成した長尺な蟻溝フレーム１と、上記蟻溝フレーム１の開口端部に着脱自在に嵌合するシート押えキャップ２とからなり、蟻溝フレーム２内に透明シートＳ１を押し込みながら透明シートＳ１を蟻溝フレーム１とシート押えキャップ２とで挟持するシートの定着装置において、シート押えキャップ２を板フレーム４と、板フレーム４の一端に設けた上下一対の二股状の支持片５と、板フレーム４の他端近傍に下方に向け起立した垂直又は傾斜した押え片６ｂとで構成している。 As the conventional film sheet mounting member, for example, the one shown in FIG. 8 and described in Japanese Patent Application Laid-Open No. 2019-62820 (Patent Document 1) is known. The film sheet mounting member described in Patent Publication 1 is designed so that even if a strong external force such as a strong wind is applied to the transparent sheet, the fixation of the sheet will not be released, it can prevent rainwater from entering, and it can also prevent the sheet from breaking. , consists of an elongated dovetail frame 1 with a narrow opening 3 at the upper end, and a sheet holding cap 2 that is removably fitted to the open end of the dovetail frame 1. In a sheet fixing device that clamps the transparent sheet S1 between a dovetail frame 1 and a sheet holding cap 2 while pushing the transparent sheet S1 into It consists of a bifurcated support piece 5 and a vertical or inclined presser piece 6b standing downward near the other end of the plate frame 4.

これにより、 シート押えキャップが板フレームと、板フレームの端部に設けた二股状の支持片と、上記板フレームの他端近傍に下方に向け起立した垂直又は傾斜した押え片とで構成させたので、これらの部材の作用で蟻溝フレームと協働して透明シートにテンションを付与しながら当該シートを定着でき、併せて、シートに強風等に強い外力が作用してもシート押えキャップが蟻溝フレームから外れるのが防止でき、また、シートの定着操作時に手を痛めず、操作性を向上させ、シートを破断させるのも防止できるとしている。 As a result, the seat presser cap is composed of a plate frame, a bifurcated support piece provided at the end of the plate frame, and a vertical or inclined presser piece standing downward near the other end of the plate frame. Therefore, these members work together with the dovetail frame to apply tension to the transparent sheet while fixing the sheet, and at the same time, even if a strong external force such as a strong wind is applied to the sheet, the sheet presser cap will not cause dovetailing. It is said that it can prevent the sheet from coming off the groove frame, it will not hurt your hands when fixing the sheet, it will improve operability, and it will also prevent the sheet from breaking.

前記発明においては、単一の押え片６ｂがあれば、前記発明の目的は達成されるが、上記押え片６ｂに対向して垂直なガイド片６ａを起立し二つの押え片６ｂとガイド片６ａとでソケット６を構成させ、更に、板フレーム４を貫通してソケット６内に嵌入するソケット拡径部材を設けても良いとしているが、実施例においては、フランジ７ａとこのフランジ７ａから延びるネジ棒からなるビス７から構成されるソケット拡径部材を設けたもののみが記載されており、シートの定着時には、硬質の透明シートＳ１を蟻溝フレーム１上に載置させ、両面粘着テープＸに貼付しておいて仮止めし、板フレーム４の右側支持片５をシートＳ１を押え込みながら蟻溝フレーム１の右側側壁１ｂの上端湾曲部１ｃに嵌合させ、ソケット６をシートＳ１を下方に押し込んでテンションを掛けながら蟻溝フレーム１の開口部３内に嵌合させ、ソケット６内にビス７を螺合させて圧入させて、それにより、ビス７の太さに対応してソケット６を拡げ、突起６ｃによりシートＳ１にテンションを付与しながら蟻溝フレーム１の左側側壁１ｂの内周に圧接させるている。すなわち、シートＳ１は蟻溝フレーム１とシート押えキャップ２とで強制的にテンションを付与されながら挟持され、屋根面上に均一に展張されている。 In the above-mentioned invention, the object of the invention is achieved if there is a single pressing piece 6b, but it is also possible to erect a vertical guide piece 6a opposite the pressing piece 6b, and to form a socket 6 with the two pressing pieces 6b and the guide piece 6a, and further to provide a socket diameter expanding member that penetrates the plate frame 4 and fits into the socket 6. However, in the examples, only a socket diameter expanding member consisting of a flange 7a and a screw 7 made of a threaded rod extending from this flange 7a is provided, and when the sheet is fixed, the hard transparent sheet S1 is inserted into the dovetail frame. The sheet S1 is placed on the roof 1, attached to the double-sided adhesive tape X for temporary fixation, and the right support piece 5 of the plate frame 4 is fitted into the upper curved part 1c of the right side wall 1b of the dovetail frame 1 while pressing down the sheet S1, the socket 6 is pressed downward to press the sheet S1 into the opening 3 of the dovetail frame 1 while applying tension, and the screw 7 is screwed into the socket 6 to press it in, thereby expanding the socket 6 according to the thickness of the screw 7, and the sheet S1 is pressed against the inner circumference of the left side wall 1b of the dovetail frame 1 while applying tension to the sheet S1 with the protrusion 6c. In other words, the sheet S1 is clamped between the dovetail frame 1 and the sheet pressing cap 2 while being forcibly applied with tension, and is evenly spread over the roof surface.

しかしながら、前記従来のフィルムシートの取付部材においては、蟻溝フレーム１上に両面粘着テープで仮止め載置した透明シートＳ１を下方に押し込んでテンションを掛けながら蟻溝フレーム１の開口部３内に右側支持片５を嵌合させ、ビス７の螺合によりソケット６を拡げテンションを付与して挟持しているだけなので、フィルムシートの定着は、実質的にビス７の螺合によるソケット６の拡径の押圧力だけで行われている状態である。このため、ビス７が入っている部分周辺は、ある程度、蟻溝フレーム１の板フレーム４に対する保持力があるものの、ビス７とビス７間においては保持力が弱くなる。すなわち、シートの定着を点で保持している状態であり、したがって、ビス７とビス７間においては、シートＳ１の谷樋に面した端部が風でめくり上がったりする場合は、フィルムシートの定着が好適に行われない場合が生じる。 However, in the conventional film sheet mounting member, the transparent sheet S1, which is temporarily fixed on the dovetail frame 1 with double-sided adhesive tape, is pressed downward to apply tension while fitting the right support piece 5 into the opening 3 of the dovetail frame 1, and the socket 6 is expanded by screwing in the screw 7 to apply tension and clamp it, so the film sheet is essentially fixed only by the pressing force of the socket 6 expanding by screwing in the screw 7. Therefore, although there is a certain degree of holding force to the plate frame 4 of the dovetail frame 1 around the part where the screw 7 is inserted, the holding force is weaker between the screws 7. In other words, the sheet is fixed at a point, and therefore, if the end of the sheet S1 facing the valley gutter is turned up by the wind between the screws 7, the film sheet may not be fixed properly.

本発明は、かかる事情に鑑みてなされたものであって、フィルムシート取付部材において、フィルムシートの保持を点ではなく、線で保持を行い、より定着力に優れるフィルムシートの取付部材を提供することを目的とする。 The present invention has been made in view of the above circumstances, and provides a film sheet mounting member that holds the film sheet not at points but in lines, and which has better fixing power. The purpose is to

そして、前記嵌合部３１の幅方向先端部は下方内方に向けて湾曲させ湾曲部３３として形成し、一方、幅方向基端部においては、凹部３４ａと凸部３４ｂを連続して断面略Ｓ字状部３４となるように形成し、前記凹部３４ａと前記凸部３４ｂによって前記突出部２６を嵌合固定時において挟持できるように形成している。 The widthwise tip of the fitting portion 31 is curved downward and inward to form a curved portion 33, while the widthwise base end is formed such that the recess 34a and the protrusion 34b are continuous to form a substantially S-shaped cross section 34, and the protrusion 26 can be clamped by the recess 34a and the protrusion 34b when the fitting is fixed.

また、前記嵌合部３１の幅方向長さＸは、前記開口部２１の幅方向長さＹより長いが、前記開口部２１に斜めに挿入可能な長さに設定している。 Further, the length X in the width direction of the fitting part 31 is longer than the length Y in the width direction of the opening 21, but is set to a length that allows the fitting part 31 to be inserted diagonally into the opening 21.

上記のように形成されるフィルムシート取付部材１０使用して前記フィルムシートＦＳを張設するには、図２（ａ）～（ｄ）に示す工程により行うと良い。 In order to stretch the film sheet FS using the film sheet attachment member 10 formed as described above, it is preferable to carry out the steps shown in FIGS. 2(a) to 2(d).

図２（ａ）～（ｄ）は前記フィルムシート取付部材１０使用して前記フィルムシートＦＳを農業用温室に張設する工程を示す要部拡大端面図である。 Figures 2(a) to 2(d) are enlarged end views of the main part showing the process of using the film sheet mounting member 10 to stretch the film sheet FS in an agricultural greenhouse.

図２に示すように、前記フィルムシート取付部材１０使用して前記フィルムシートＦＳを農業用温室に張設するには、まず、図２（ａ）に示すように、農業用温室に前記シート受部材２０を取り付け、その上に前記フィルムシートＦＳを載置する。 As shown in FIG. 2, in order to install the film sheet FS in an agricultural greenhouse using the film sheet mounting member 10, first, as shown in FIG. The member 20 is attached and the film sheet FS is placed thereon.

次に図２（ｂ）に示すように、前記シート押さえ部材３０を前記シート受部材２０の前記開口部２１に前記湾曲部３３を斜めから突入させる。 Next, as shown in FIG. 2(b), the sheet pressing member 30 is caused to obliquely enter the curved portion 33 into the opening 21 of the sheet receiving member 20. Then, as shown in FIG.

そして、図２（ｃ）に示すように、前記シート押さえ部材３０を前記シート受部材２０の奥隅に突入させて、前記断面略Ｓ字状部３４を前記シート受部材２０の溝内において、前記凹部３４ａが前記突出部２６に嵌め込まれ、前記突出部２６を前記凹部３４ａと前記凸部３４ｂによって挟持するように嵌め込むのである。 Then, as shown in FIG. 2(c), the sheet pressing member 30 is pushed into the inner corner of the sheet receiving member 20, and the substantially S-shaped section 34 is placed in the groove of the sheet receiving member 20. The recess 34a is fitted into the protrusion 26, and the protrusion 26 is inserted so as to be sandwiched between the recess 34a and the protrusion 34b.

この状態においては、前記シート押さえ部材３０は、前記シート受部材２０の溝内において、遊嵌されている状態であり、前記シート押さえ部材３０は、前記シート受部材２０の溝内において幅方向にスライド可能な状態である。 In this state, the sheet pressing member 30 is loosely fitted in the groove of the sheet receiving member 20, and the sheet pressing member 30 is capable of sliding in the width direction within the groove of the sheet receiving member 20.

そして、その状態で、図２（ｃ）の矢印の方向に、前記湾曲部３３側の前記フィルムシートＦＳを引っ張ると、図２（ｄ）に示すように、前記シート押さえ部材３０は前記突出部２６側にスライド移動し、前記フィルムシートＦＳは、前記断面略Ｓ字状部３４と前記突出部２６により嵌合固定されると共に、前記湾曲部３３は、前記突出部２５に当接し規制されて、その状態で固定される。 In this state, when the film sheet FS on the curved portion 33 side is pulled in the direction of the arrow in FIG. 2(c), the sheet pressing member 30 slides toward the protruding portion 26 as shown in FIG. 2(d), and the film sheet FS is fitted and fixed by the S-shaped cross-section portion 34 and the protruding portion 26, while the curved portion 33 abuts against and is restricted by the protruding portion 25, and is fixed in this state.

そして、その前記フィルムシートＦＳが嵌合固定された状態で、タッピンビスＢを前記ネジ取付部３２に開けられたネジ孔（図示せず）から前記ネジ保持溝２７にねじ込み、前記シート押さえ部材３０を前記シート受部材２０に対して位置固定するのである。 Then, with the film sheet FS fitted and fixed, a tapping screw B is screwed into the screw holding groove 27 from a screw hole (not shown) drilled in the screw attachment part 32, and the sheet holding member 30 is screwed into the screw holding groove 27. The position is fixed relative to the seat receiving member 20.

本発明に係るフィルムシート取付部材１０は以上のように取り付けられるので、前記フィルムシートＦＳは、前記断面略Ｓ字状部３４と前記突出部２６とによる嵌合固定及び前記湾曲部３３と前記突出部２５との挟持固定により、前記シート押さえ部材３０を前記シート受部材２０の長手方向の全長に亘り、線状に固定されることとなり、部分的に固定状態に強弱が生じることはない。また、前記シート押さえ部材３０は、前記シート受部材２０の溝に、スライド代をもって遊嵌されるため、張設される前記フィルムシートＦＳの厚さが限定されず、また、硬質シート及び軟質シートのいずれにも対応できる。さらに、嵌合状態における組み付け精度も厳密には要求されず、設計の自由度が増すこととなる。 Since the film sheet mounting member 10 according to the present invention is attached as described above, the film sheet FS is fixed linearly to the sheet pressing member 30 over the entire length of the sheet receiving member 20 in the longitudinal direction by the engagement and fixation of the approximately S-shaped cross-section portion 34 and the protruding portion 26 and the clamping and fixation of the curved portion 33 and the protruding portion 25, and there is no partial strength or weakness in the fixed state. In addition, since the sheet pressing member 30 is loosely fitted into the groove of the sheet receiving member 20 with a sliding allowance, the thickness of the film sheet FS to be stretched is not limited, and it can be used with both hard and soft sheets. Furthermore, there is no strict requirement for assembly accuracy in the fitted state, which increases the freedom of design.

上記のように形成されるフィルムシート取付部材１０を使用して前記フィルムシートＦＳを農業用温室の屋根に張設する場合においては、例えば、次のような構造の農業用温室が好適である。 When using the film sheet mounting member 10 formed as described above to attach the film sheet FS to the roof of an agricultural greenhouse, for example, an agricultural greenhouse having the following structure is suitable.

図３は本発明にかかる農業用温室の要部斜視図であり、図４は同農業用温室の屋根面の要部拡大図であり、図５（ａ）は図４のＡ－Ａ部分拡大図であり、（ｂ）は同Ｂ－Ｂ部分拡大図である。また、図６（ａ）はフィルムシートの取付機構を示す要部拡大断面図であり、（ｂ）は（ａ）の要部拡大平面図である。
 FIG. 3 is a perspective view of the main parts of the agricultural greenhouse according to the present invention, FIG. 4 is an enlarged view of the main parts of the roof surface of the agricultural greenhouse, and FIG. 5(a) is an enlarged view of the section AA in FIG. FIG. 3(b) is a partially enlarged view taken along line BB. Moreover, FIG. 6(a) is an enlarged cross-sectional view of the main part showing the attachment mechanism of the film sheet, and FIG. 6(b) is an enlarged plan view of the main part of FIG. 6(a).

図３乃至図５において、５０は間口方向に連設している連棟型の農業用温室であり、５１は支柱である。前記支柱５１は、奥行方向および間口方向に複数本が夫々立設されている。前記支柱５１の上部には間口方向に向けてトラス梁５８を架設している。 In FIGS. 3 to 5, 50 is a multi-building type agricultural greenhouse that is connected in the frontage direction, and 51 is a support. A plurality of the pillars 51 are erected in the depth direction and the frontage direction. A truss beam 58 is installed above the support column 51 in the direction of the frontage.

前記支柱５１の上部には、複数の合掌材５２を頂部において山型となるように突合状態で奥行方向に向けて並設している。また、前記合掌材５２の頂部には、奥行方向に向けて、長尺状の棟材５３を架設している。前記棟材５３を支点として開閉自在の天窓５４を設けている。前記天窓５４の下部を支持すべく前記合掌材５２の上部に奥行方向に向けて母屋材５６架設される。前記母屋材５６は、図６（ａ）及び（ｂ）にも詳細に示すとおり、前記合掌材５２に取り付けられる。前記母屋材５６は前記合掌材５２よりも幅の広い略Ｌ字状のアングル材５５により、ボルトＢとナットＮにより螺設され取り付けられており、前記母屋材５６は、二組の前記ボルトＢとナットＮの螺合により、前記合掌材５２の斜面上を上下移動して位置調整を行うことができる。また、連棟部を支持する支柱５１上部には谷樋５７を、奥行方向に向けて架設している。 On the top of the support 51, multiple gable members 52 are arranged in a line in the depth direction, butting together at the top to form a mountain shape. In addition, a long ridge member 53 is erected on the top of the gable member 52 in the depth direction. A skylight 54 that can be opened and closed is provided with the ridge member 53 as a fulcrum. A purlin member 56 is erected on the top of the gable member 52 in the depth direction to support the lower part of the skylight 54. The purlin member 56 is attached to the gable member 52 as shown in detail in Figures 6 (a) and (b). The purlin member 56 is attached to the gable member 52 by an approximately L-shaped angle member 55 that is wider than the gable member 52, and is screwed in with a bolt B and a nut N. The purlin member 56 can be moved up and down on the slope of the gable member 52 by screwing in two sets of the bolts B and nuts N, and the position can be adjusted by moving the purlin member 56 up and down on the slope of the gable member 52. In addition, a valley gutter 57 is installed in the depth direction on the top of the support pillars 51 that support the connecting section.

そして、前記母屋材５６の上面には前記フィルムシート取付部材１０を取り付けると共に、前記谷樋５７の上面にも前記フィルムシート取付部材１０を取り付けて、この間にフィルムシートＦＳを張設するのである。 The film sheet mounting member 10 is then attached to the upper surface of the purlin material 56, and also to the upper surface of the valley gutter 57, and the film sheet FS is stretched between them.

図７は、上記のように構成される農業用温室５０に、前記フィルムシート取付部材１０によって前記フィルムシートＦＳを張設する工程を示す。 FIG. 7 shows a process of tensioning the film sheet FS using the film sheet attachment member 10 in the agricultural greenhouse 50 configured as described above.

まず、前記母屋材５６を、図６の破線で示すように、前記ボルトＢと前記ナットＮの螺合を緩めて、下方に位置するように調整しておく。 First, as shown by the broken line in FIG. 6, the bolt B and the nut N are loosened, and the purlin material 56 is adjusted so as to be positioned downward.

次に、図７（ａ）に示すように、前記母屋材５６の上面に取り付けられた前記シート受部材２０と前記谷樋５７の上面に取り付けられた前記シート受部材２０との間に前記フィルムシートＦＳを載置する。このとき、前記シート受部材２０,２０は、前記湾曲部３３が互いに向かい合うように取り付けられている。 Next, as shown in FIG. 7(a), the film sheet FS is placed between the sheet receiving member 20 attached to the upper surface of the purlin material 56 and the sheet receiving member 20 attached to the upper surface of the valley gutter 57. At this time, the sheet receiving members 20, 20 are attached so that the curved portions 33 face each other.

なお、このとき、図３に示すように、巻回された前記フィルムシートＦＳを一方の妻面から、他方の妻面に向けて巻き外すようにして載置すると作業性が良好となる。前記フィルムシートＦＳは通常巻回された状態で販売されており、前記フィルムシートＦＳの幅と前記母屋材５６と前記谷樋５７間の幅長を一致させると、前記フィルムシートＦＳを前記農業温室５０における所要の寸法に幅長を裁断することなく、巻回状態のまま使用することができるので、さらに作業性が高まる。 In addition, at this time, as shown in FIG. 3, if the wound film sheet FS is placed so as to be unwound from one end surface toward the other end surface, the workability will be improved. The film sheet FS is usually sold in a rolled state, and when the width of the film sheet FS and the width between the purlin material 56 and the valley gutter 57 are matched, the film sheet FS can be rolled into the agricultural greenhouse. Since it can be used in the wound state without cutting the width to the required size at 50, the workability is further improved.

次に、図７（ｂ）に示すように、前記シート押さえ部材３０を前記シート受部材２０の前記開口部２１に前記湾曲部３３を斜めから突入させ、前記シート押さえ部材３０を前記シート受部材２０の奥隅に突入させて、前記断面略Ｓ字状部３４を前記シート受部材２０の溝内において、前記凹部３４ａが前記突出部２６に嵌め込まれ、前記突出部２６を記凹部３４ａと前記凸部３４ｂによって挟持するように嵌め込む。 Next, as shown in FIG. 7(b), the curved portion 33 of the sheet pressing member 30 is inserted obliquely into the opening 21 of the sheet receiving member 20, and the sheet pressing member 30 is inserted into the inner corner of the sheet receiving member 20, so that the approximately S-shaped cross-section portion 34 is inserted into the groove of the sheet receiving member 20, the recess 34a is fitted into the protruding portion 26, and the protruding portion 26 is sandwiched between the recess 34a and the protruding portion 34b.

次に、前記母屋材５６を、予め緩めてあった前記ボルトＢと前記ナットＮを締めて、図６の実線で示すように、上方に移動させ、前記フィルムシートを上方に引っ張り上げて、図７（ｃ）に示すように、前記フィルムシート取付部材１０において、前記湾曲部３３を上方に持ち上げ、前記突出部２５に当接させて前記フィルムシートＦＳを挟持すると共に、前記突出部２６側にスライド移動させ、前記断面略Ｓ字状部３４と前記突出部２６に前記フィルムシートＦＳを挟持して固定させる。 Next, the bolt B and nut N, which were loosened beforehand, are tightened to move the purlin material 56 upward as shown by the solid line in FIG. 6, and the film sheet is pulled upward. As shown in FIG. 7(c), the curved portion 33 of the film sheet mounting member 10 is lifted upward and abutted against the protruding portion 25 to clamp the film sheet FS, and is slid toward the protruding portion 26, so that the film sheet FS is clamped and fixed between the cross-sectionally approximately S-shaped portion 34 and the protruding portion 26.

そして、前記フィルムシートＦＳが嵌合固定された状態で、タッピングビスＴＢを前記ネジ取付部３２に開けられたネジ孔（図示せず）から前記ネジ保持溝２７にねじ込み、前記シート押さえ部材３０を前記シート受部材２０に対して位置固定するのである。 Then, with the film sheet FS fitted and fixed, a tapping screw TB is screwed into the screw retaining groove 27 through a screw hole (not shown) opened in the screw mounting portion 32, and the sheet pressing member 30 is fixed in position relative to the sheet receiving member 20.

以上の農業用温室５０によると、前記シート押さえ部材３０を前記シート受部材２０の長手方向の全長に亘り、線状に固定されることとなり、部分的に固定状態に強弱が生じることはない。また、前記シート押さえ部材３０は、前記シート受部材２０の溝に、スライド代をもって遊嵌されるため、張設される前記フィルムシートＦＳの厚さが限定されず、また、硬質シート及び軟質シートのいずれにも対応できる。さらに、嵌合状態における組み付け精度も厳密には要求されず、設計の自由度が増すこととなる。 According to the agricultural greenhouse 50 described above, the sheet pressing member 30 is linearly fixed over the entire length of the sheet receiving member 20 in the longitudinal direction, and there is no possibility that the strength of the fixed state is partially different. Further, since the sheet pressing member 30 is loosely fitted into the groove of the sheet receiving member 20 with a sliding allowance, the thickness of the film sheet FS to be stretched is not limited, and the thickness of the film sheet FS is not limited. It can correspond to both. Furthermore, assembly accuracy in the fitted state is not strictly required, and the degree of freedom in design increases.

さらに、前記農業用温室５０においては、垂木材を必要としないため、構造を簡略化することができる。 Furthermore, the agricultural greenhouse 50 does not require rafters, so the structure can be simplified.

なお、前記フィルムシートＦＳを張設する機構としては、図６に示すように、前記合掌材５２の上部に取り付けた略Ｌ字状のアングル材５５と、前記アングル材５５にボルトＢとナットＮにより螺設された前記母屋材５６とにより構成したが、これに限定されないことは言うまでもない。 The mechanism for stretching the film sheet FS is, as shown in FIG. Although the main building material 56 is constructed by screwing the main building material 56, it goes without saying that the present invention is not limited thereto.

また、前記フィルムシート取付部材１０が取り付けられる温室は農業用に限定されず、他の用途に用いられるものであっても良い。 Further, the greenhouse to which the film sheet attachment member 10 is attached is not limited to agricultural use, and may be used for other purposes.
