Description

この考案は、図６と図７に例示したように、開口部が幅狭のシート止着溝１０ａを有するシート止め材１０の前記シート止着溝１０ａの上に拡げた、ビニルハウス等の農業用温室２０の被覆材であるシート１１を、前記シート止着溝１０ａ内へ押し込みつつ挿入して止着する弾性な波形シート止め線１による止着構造の技術分野に属する。   As illustrated in FIG. 6 and FIG. 7, the present invention is an agriculture such as a vinyl house that is expanded on the sheet fixing groove 10 a of the sheet fixing material 10 having a sheet fixing groove 10 a having a narrow opening. It belongs to the technical field of the fastening structure by the elastic corrugated sheet fastening line 1 that inserts and fastens the sheet 11 that is a covering material of the greenhouse 20 for use while being pushed into the sheet fastening groove 10a.

ビニルハウス等の農業用温室２０は、一般に、パイプ材や軽量鉄骨等でハウス骨組１２を組み立て、同ハウス骨組１２の外側面の桁行方向や梁間方向等に上記のシート止め材１０を取り付け、同シート止め材１０のシート止着溝１０ａの上に拡げた、ハウス被覆材としてのシート１１を、弾性な波形シート止め線１によりシート止着溝１０ａ内へ押し込みつつ挿入して止め付ける手法で構築されている（例えば、特許文献１〜３を参照）。   An agricultural greenhouse 20 such as a vinyl house generally assembles a house frame 12 with pipe materials, lightweight steel frames, etc., and attaches the above-mentioned sheet stoppers 10 in the direction of the beam of the outer side of the house frame 12 or the direction between beams. Constructed by a technique in which a sheet 11 as a house covering material expanded on the sheet fixing groove 10a of the sheet fixing material 10 is inserted into the sheet fixing groove 10a by an elastic corrugated sheet fixing line 1 and fixed. (For example, see Patent Documents 1 to 3).

前記シート止め材１０のシート止着溝１０ａは、横断面をみると、底面部の両側に立ち上がる両溝壁を漸次内方へ傾斜させて開口部が幅狭となるように形成されている。前記波形シート止め線１は、その（振動の）幅が、前記シート止着溝１０ａの開口部の幅寸よりも大きく形成されている。
ちなみに図６中の符号１０ｂ、１０ｃは、シート止め材１０の両溝壁の天端部に形成した内向きのカール部を示し、符号１０ｄは、シート止め材１０の底面部の軸線方向中央部に形成した凹溝部を示している。該凹溝部１０ｄは、シート止め材１０をハウス骨組１２へビス止めする際に有効利用される。 The sheet fixing groove 10a of the sheet fixing material 10 is formed such that, when viewed in cross section, both groove walls rising on both sides of the bottom surface portion are gradually inclined inward to narrow the opening. The corrugated sheet retaining line 1 has a width (vibration) larger than the width of the opening of the sheet securing groove 10a.
Incidentally, reference numerals 10b and 10c in FIG. 6 denote inwardly curled portions formed at the top end portions of both groove walls of the sheet stopper material 10, and reference numeral 10d denotes an axially central portion of the bottom surface portion of the sheet stopper material 10. The recessed groove part formed in is shown. The concave groove portion 10d is effectively used when the sheet stopper 10 is screwed to the house framework 12.

前記波形シート止め線１は、その寸法や材質、構成等が既に広く標準化されている。具体的には、道路搬送上の規制等を勘案して、２ｍ程度の長さで定寸切断して出荷されたものが好適に用いられている。線径は２．０〜２．３ｍｍが一般的である。材質は、スプリング性に富む中或いは高炭素鋼とされ、通例その表面に亜鉛メッキ等が施されている。構成は、ほぼ台形波状タイプ（同一台形が交互に反転して連続するような形状）のほか、ほぼ半円弧波状タイプ（同一半円弧が交互に反転して連続するような形状）も用いられている（例えば、特許文献２を参照）。波形の形態は、一例として、（振動の）幅が３３〜３５ｍｍ程度、一波長のピッチが１０５〜１２０ｍｍ程度とされている。
前記シート止め材１０は、道路搬送上の規制のほか、現場で作業者が一人で持ち運ぶことができ、且つスムーズに取付作業を行うことができる重量等を勘案し、３〜６ｍ程度の長さで定寸切断して出荷されたものが好適に用いられている。
前記シート１１は、例えば、ポリオレフィンシート、塩化ビニルシート、又はプラスチックフィルムシートが好適に用いられている。１枚で実施する場合もあるし、２枚重ねで実施する場合もある。 The corrugated sheet retaining line 1 has already been widely standardized in size, material, configuration and the like. Specifically, in consideration of restrictions on road transportation and the like, those that have been shipped after being cut to a length of about 2 m are preferably used. The wire diameter is generally 2.0 to 2.3 mm. The material is medium or high carbon steel with high spring properties, and the surface is usually galvanized. In addition to the almost trapezoidal wave type (a shape in which the same trapezoid is alternately reversed and continuous), a substantially semicircular wave type (a shape in which the same semicircular arc is alternately reversed and continuous) is also used. (For example, refer to Patent Document 2). As an example, the waveform has a width (of vibration) of about 33 to 35 mm and a pitch of one wavelength of about 105 to 120 mm.
The sheet stopper 10 has a length of about 3 to 6 m in consideration of restrictions on road transportation, a weight that can be carried by a worker alone on the site, and can be mounted smoothly. Those that have been shipped after being cut to a certain size are preferably used.
For example, a polyolefin sheet, a vinyl chloride sheet, or a plastic film sheet is preferably used as the sheet 11. In some cases, it may be carried out by one sheet, or in two layers.

従来のビニルハウスにおけるシートの止着作業は、ハウス骨組１２に取り付けたシート止め材１０のシート止着溝１０ａ内に、図８Ａ、Ｂに示したように、左右に隣接する波形シート止め線１、１’同士を一連に突き合うように（連続するように）継ぎ足して止着する手法が一般的であった。
具体的には、シート止め材１０の開口部の上にシート１１（図８では図示の便宜上省略）を拡げ、その上から先ず、左側の波形シート止め線１の左方の挿入始端をシート止着溝１０ａ内の一方の溝壁へほぼ平行に当てがう姿勢でシートと共に押し込み、続く台形波の山部の角を他方の溝壁へ向かって押し入れる作業を、該波形シート止め線１の右方の端末部まで繰り返し行い、次に、該端末部と連続するように右側の波形シート止め線１’の左方の挿入始端を前記端末部に一連に突き合わせつつシート止着溝１０ａ内の一方の溝壁へほぼ平行に当てがう姿勢でシートと共に押し込み、続く台形波の山部の角を他方の溝壁へ向かって押し入れる作業を、該波形シート止め線１’の右方の端末部まで繰り返し行っていた。以後、図示は省略するが、前述した波形シート止め線１’の止着作業と同様の手法で、所要数の波形シート止め線を、一定方向のシート止め材１０の全長にわたり順次行っていた。 As shown in FIGS. 8A and 8B, the corrugated sheet retaining line 1 adjacent to the left and right in the sheet retaining groove 10a of the sheet retaining member 10 attached to the house framework 12 is used to secure the sheet in the conventional vinyl house. In general, a technique is used in which 1 ′ are joined together so as to face each other (continuously) and fixed.
Specifically, the sheet 11 (not shown in FIG. 8 is omitted for convenience) is spread over the opening of the sheet stopper 10, and from the top, the left insertion start end of the left corrugated sheet stopper line 1 is fixed to the sheet. The operation of pushing together with the sheet in a posture that is almost parallel to one groove wall in the landing groove 10a, and pushing the corner of the trapezoidal wave peak toward the other groove wall is performed on the corrugated sheet retaining line 1. Repeat until the right terminal portion, and then continuously insert the left insertion start end of the right corrugated sheet retaining line 1 ′ into the terminal portion so as to be continuous with the terminal portion. Pushing together with the sheet in a posture almost parallel to one groove wall, and pushing the corner of the trapezoidal wave peak toward the other groove wall, the terminal on the right side of the corrugated sheet retaining line 1 ′ Repeated to part. Thereafter, although not shown in the drawings, the required number of corrugated sheet retaining lines are sequentially performed over the entire length of the sheet retaining material 10 in a certain direction by the same method as that for fixing the corrugated sheet retaining line 1 ′ described above.

ちなみに、前記波形シート止め線１、１’の止着作業は手作業で行う場合もあるし、止着工具を用いて行う場合もある。また、前記波形シート止め線１、１’の定寸切断の位置は、同線材の製造機械の仕組み上、切断しやすい台形波の山の部分の中間位置とするのが一般的である。   Incidentally, the fixing operation of the corrugated sheet fixing lines 1, 1 'may be performed manually or may be performed using a fixing tool. Further, the position of the sizing cut of the corrugated sheet retaining lines 1 and 1 ′ is generally set at an intermediate position of a trapezoidal wave peak portion that is easy to cut due to the mechanism of the manufacturing machine of the wire.

波形シート止め線１、１による止着構造は、該止め線１、１’が、シート止め材１０のシート止着溝１０ａ内から外方へ飛び出ないようにすることが肝要であり、この点が止着構造全体の引張強度（止着強度）に強い影響を与える。
図９は、シート止め材１０にシート１１と共に止着した波形シート止め線１の止着構造の引張強度を測定するための試験を概略的に示している。
この引張試験は、図８に示す止着構造について、幅１００ｃｍの２枚重ねのポリオレフィンシート１１（１枚の厚み０．１５ｍｍ）を、左右に隣接（連続）する波形シート止め線１、１’で均等（符号Ｘ線を境界線として左右）に各５０ｃｍずつシート止め材１０に止着してなる止着構造の引張強度を測定するものであり、該シート止め材１０を固定した状態で、前記シート１１の一側（図示例ではカール部１０ｂの外方へ延設した側）の端部（上端部）を巻装した回転機１３を回転させることによりトルク荷重を徐々にかけて前記止着構造の止着状態の目視確認を行った。 The fastening structure using the corrugated sheet retaining lines 1 and 1 is important to prevent the retaining lines 1 and 1 'from jumping out from the inside of the sheet fastening groove 10a of the sheet fastening material 10. Strongly affects the tensile strength (fastening strength) of the fastening structure as a whole.
FIG. 9 schematically shows a test for measuring the tensile strength of the fastening structure of the corrugated sheet fastening line 1 fastened to the sheet fastening material 10 together with the sheet 11.
In this tensile test, corrugated sheet retaining lines 1, 1 ′ adjacent to (continuous) two sheets of a polyolefin sheet 11 (one thickness of 0.15 mm) having a width of 100 cm for the fastening structure shown in FIG. In the state where the tensile strength of the fastening structure formed by fastening to the sheet stopper 10 by 50 cm each equally (left and right with the X-ray as a boundary line) is fixed, and the sheet stopper 10 is fixed, The fastening structure is configured so that a torque load is gradually applied by rotating a rotating machine 13 wound around an end (upper end) of one side of the sheet 11 (in the illustrated example, the side extending outward from the curled portion 10b). Visual confirmation of the fixed state of was performed.

その結果、図８Ａに係る止着構造は、測定値が３５０ｋｇｆ・ｃｍの段階で、左右の波形シート止め線１、１’の突き合わせ端部が、ともにシート止め材１０（シート止着溝１０ａ）から飛び出した。よって、引張強度は、３５０ｋｇｆ・ｃｍ程度と考えられる。
一方、図８Ｂに係る止着構造は、測定値が２００ｋｇｆ・ｃｍの段階で、左右の波形シート止め線１、１’の突き合わせ端部が、ともにシート止め材１０から飛び出した。よって、引張強度は、２００ｋｇｆ・ｃｍ程度と考えられる。 As a result, in the fastening structure according to FIG. 8A, when the measured value is 350 kgf · cm, the butt end portions of the left and right corrugated sheet fastening lines 1 and 1 ′ are both the sheet fastening material 10 (sheet fastening groove 10 a). Jumped out of. Therefore, the tensile strength is considered to be about 350 kgf · cm.
On the other hand, in the fastening structure according to FIG. 8B, the butt end portions of the left and right corrugated sheet fastening lines 1, 1 ′ jumped out of the sheet fastening material 10 when the measured value was 200 kgf · cm. Therefore, the tensile strength is considered to be about 200 kgf · cm.

参考のため、図１０と図１１に示した止着構造についても同様の引張試験を行った。ちなみに、図１０Ａ、Ｂは、左右に隣接する波形シート止め線１、１’同士を突き合わせないで継ぎ足した止着構造を示している。図１１Ａ、Ｂは、１本物の波形シート止め線１の止着構造を示している。
その結果、図１０Ａに係る止着構造は、測定値が１９０ｋｇｆ・ｃｍの段階で、右側の波形シート止め線１’の左端部がシート止め材１０から飛び出した。よって、引張強度は、１９０ｋｇｆ・ｃｍ程度と考えられる。
一方、図１０Ｂに係る止着構造は、測定値が１５０ｋｇｆ・ｃｍの段階で、左側の波形シート止め線１の右端部がシート止め材１０から飛び出した。よって、引張強度は、１５０ｋｇｆ・ｃｍ程度と考えられる。
続いて、図１１Ａに係る止着構造は、測定値が４００ｋｇｆ・ｃｍの段階であっても、一本物の波形シート止め線１の止着状態に特に変化はなかった。
一方、図１１Ｂに係る止着構造も、測定値が４００ｋｇｆ・ｃｍの段階であっても、一本物の波形シート止め線１の止着状態に特に変化はなかった。 For reference, the same tensile test was performed on the fastening structures shown in FIGS. Incidentally, FIGS. 10A and 10B show a fastening structure in which corrugated sheet fastening lines 1 and 1 ′ adjacent to each other on the left and right sides are joined without being brought into contact with each other. 11A and 11B show the fastening structure of a single corrugated sheet fastening line 1.
As a result, in the fastening structure according to FIG. 10A, the left end portion of the right corrugated sheet fastening line 1 ′ jumped out of the sheet fastening material 10 when the measured value was 190 kgf · cm. Therefore, the tensile strength is considered to be about 190 kgf · cm.
On the other hand, in the fastening structure according to FIG. 10B, the right end portion of the left corrugated sheet fastening line 1 jumped out of the sheet fastening material 10 when the measured value was 150 kgf · cm. Therefore, the tensile strength is considered to be about 150 kgf · cm.
Subsequently, in the fastening structure according to FIG. 11A, there was no particular change in the fastening state of the single corrugated sheet fastening line 1 even when the measured value was 400 kgf · cm.
On the other hand, even in the fastening structure according to FIG. 11B, there was no particular change in the fastening state of the single corrugated sheet fastening line 1 even when the measured value was at the stage of 400 kgf · cm.

以上、前記引張試験の結果を対比検討すると、図８Ａ、Ｂに係る左右に隣接する波形シート止め線１、１’を突き合わせて継ぎ足した止着構造は、該止め線１、１’の山部の向きによって引張強度が異なるという方向性を有するものの、図１０Ａ、Ｂに係る左右に隣接する波形シート止め線１、１’を突き合わせないで継ぎ足した止着構造と比し、総じて引張強度が高いと判断することができ、一応の効果はあると云える。
しかしながら、前記止め線１、１’の山部の向きによって引張強度が異なるという方向性をほぼ解消し、図１１Ａ、Ｂに係る一本物の波形シート止め線１を用いた止着構造の引張強度に近づけることができれば、より有益であることは明らかである。 As described above, when the results of the tensile test are compared, the fastening structure in which the corrugated sheet fastening lines 1 and 1 'adjacent to the left and right according to FIGS. Although the tensile strength varies depending on the orientation of the sheet, the tensile strength is generally higher than that of the fastening structure in which the corrugated sheet fastening lines 1 and 1 ′ adjacent to the left and right sides according to FIGS. It can be determined that there is a temporary effect.
However, the directionality in which the tensile strength varies depending on the direction of the peak portions of the retaining lines 1 and 1 ′ is almost eliminated, and the tensile strength of the fastening structure using the single corrugated sheet retaining line 1 according to FIGS. It is clear that it is more useful if it can be approached.

したがって、本考案の目的は、従来一般に行われている左右に隣接する波形シート止め線１、１’同士を突き合わせた止着構造（図８Ａ、Ｂ参照）と比し、部材点数や作業工程を増やすことなく、継ぎ足す側の波形シート止め線１’の止着（止め付け）手法に工夫を施すことにより、経済的かつ合理的に引張強度を高めることができる、波形シート止め線の止着構造を提供することにある。   Therefore, the object of the present invention is compared with the fastening structure (see FIGS. 8A and 8B) in which the corrugated sheet fastening lines 1 and 1 'adjacent to each other on the left and right are generally used, and the number of members and work processes are reduced. It is possible to increase the tensile strength economically and reasonably by fixing the corrugated sheet fastening line 1 'on the side to be added without increasing the number. To provide a structure.

開口部が幅狭のシート止着溝を有するシート止め材のシート止着溝内へシートを押し込みつつ挿入して止着する弾性な波形シート止め線による止着構造であって、
前記シート止着溝内へ先行して止着した波形シート止め線の端末部において少なくとも１／２波長相当の長さ部分をラップさせて後付け波形シート止め線の先端部分をシート止着溝内へ押し込み止着されていることを特徴とする。 As a means for solving the above-mentioned problem, the fastening structure of the corrugated sheet fastening line according to the device described in claim 1 is:
It is a fastening structure with an elastic corrugated sheet fastening line that is inserted and fastened while pushing the sheet into the sheet fastening groove of the sheet fastening material having a narrow sheet fastening groove in the opening,
At the end portion of the corrugated sheet retaining line that has been secured in advance in the sheet fastening groove, a length portion corresponding to at least a half wavelength is wrapped so that the leading end portion of the retrofitting corrugated sheet fastening line enters the sheet fastening groove. It is characterized by being pressed and fixed.

請求項２に記載した考案は、請求項１に記載した考案に係る波形シート止め線の止着構造において、前記波形シート止め線は、ほぼ台形波状に形成されていること、又は、ほぼ半円弧波状に形成されていることを特徴とする。   According to a second aspect of the present invention, there is provided a corrugated sheet retaining line fixing structure according to the first aspect, wherein the corrugated sheet retaining line is formed in a substantially trapezoidal wave shape, or a substantially semicircular arc. It is characterized by being formed in a wave shape.

請求項３に記載した考案は、請求項１又は２に記載した考案に係る波形シート止め線の止着構造において、前記波形シート止め線の端部における少なくとも１／２波長相当の長さ部分の表面に、波形シート止め線の地色とは異なる色彩が着色されていることを特徴とする。   According to a third aspect of the present invention, there is provided a corrugated sheet retaining line fastening structure according to the first or second aspect of the present invention, wherein the corrugated sheet retaining line has an end portion corresponding to at least a half wavelength. A color different from the ground color of the corrugated sheet retaining line is colored on the surface.

本考案に係る波形シート止め線の止着構造によれば、止着強度が低いと懸念される波形シート止め線の端末部を、継ぎ足す側の波形シート止め線の始端部（挿入始端）で押さえつけて補強する構成で実施するので、従来一般に行われている左右に隣接する波形シート止め線同士を突き合わせた止着構造（図８Ａ、Ｂ参照）と比し、止着構造全体の引張強度を飛躍的に高めることができる。さらには、一本物の波形シート止め線を用いた止着構造の引張強度に匹敵するほどに高めることができる。ひいては、突風や強風等によりシートが外れにくい、耐用性とメンテナンス性に優れたビニルハウス等の農業用温室を実現することができる。
また、部材点数や作業工程を一切増やすことなく実施できるので、非常に経済的かつ合理的である。
さらに、隣接する波形シート止め線の端部同士を互い違いの配置（クロス配置）にラップさせて実施する場合は、該止め線の端部を一見して判別できるので、シートの張り替え作業を滞りなく速やかに行うことができる。隣接する波形シート止め線の端部同士を重ね合わせ配置にラップさせて実施する場合は、該端部を地色とは異なる色で着色表示することにより、該止め線の端部を一見して判別できるので、シートの張り替え作業を滞りなく速やかに行うことができる。 According to the fastening structure of the corrugated sheet retaining line according to the present invention, the end portion of the corrugated sheet retaining line, which is concerned that the fastening strength is low, is added at the start end (insertion start end) of the corrugated sheet retaining line on the side to be added. Since it is implemented with a structure that presses down and reinforces, the tensile strength of the entire fastening structure is compared with the fastening structure (see FIGS. 8A and 8B) in which the corrugated sheet fastening lines adjacent to the left and right are generally abutted. It can be improved dramatically. Furthermore, it can be increased to be comparable to the tensile strength of a fastening structure using a single corrugated sheet fastening line. As a result, it is possible to realize an agricultural greenhouse such as a vinyl house, which has excellent durability and maintainability, in which the sheet is not easily detached due to gusts or strong winds.
Moreover, since it can implement without increasing the number of members and work processes at all, it is very economical and rational.
In addition, when the ends of adjacent corrugated sheet retaining lines are wrapped in a staggered arrangement (crossed arrangement), the ends of the retaining lines can be discriminated at a glance, so that the sheet replacement work can be performed without delay. It can be done promptly. When the ends of adjacent corrugated sheet retaining lines are overlapped and overlapped, the ends are colored and displayed in a color different from the ground color, so that the ends of the retaining lines can be seen at a glance. Since the determination can be made, the sheet replacement work can be performed promptly without any delay.

図１は、本考案に係る波形シート止め線１、１’の止着構造の枢要部を示している。
この波形シート止め線１、１’の止着構造は、開口部が幅狭のシート止着溝１０ａを有するシート止め材１０のシート止着溝１０ａ内へシート１１（図示の便宜上省略）を押し込みつつ挿入して止着する弾性な波形シート止め線１、１’による止着構造であり、前記シート止着溝１０ａ内へ先行して止着した波形シート止め線１の端末部において少なくとも１／２波長（図１では１波長）相当の長さ部分をラップさせて後付け波形シート止め線１’の先端部分をシート止着溝１０ａ内へ押し込み止着されていることを特徴とする。 FIG. 1 shows a pivotal portion of a fastening structure for corrugated sheet fastening lines 1, 1 ′ according to the present invention.

It is a fastening structure with elastic corrugated sheet retaining lines 1, 1 ′ that are inserted and secured while being at least 1 / at the end of the corrugated sheet retaining line 1 that has been secured in advance into the seat securing groove 10 a. A length portion corresponding to two wavelengths (one wavelength in FIG. 1) is wrapped, and the leading end portion of the retrofitting corrugated sheet fixing line 1 ′ is pushed into the sheet fixing groove 10a to be fixed.

要するに、本出願人は、上述の図９に示した引張試験の結果を踏まえ（段落[0008]、[0009]参照）、部材点数や作業工程を極力増やすことなく、先付けした波形シート止め線１の端末部の止着（定着）強度をいかにして高めるかを熟慮・検討した結果、該端末部と、後付けする波形シート止め線１の始端部とを所要の長さラップさせて補強することを案出した。   In short, based on the results of the tensile test shown in FIG. 9 described above (see paragraphs [0008] and [0009]), the applicant of the present invention has attached the corrugated sheet retaining line 1 that has been advanced without increasing the number of members and work steps as much as possible. As a result of careful consideration and examination of how to increase the fastening (fixing) strength of the terminal part of the terminal, the terminal part and the starting end part of the corrugated sheet fastening line 1 to be retrofitted are wrapped for a required length and reinforced. Devised.

具体的には、シート止め材１０の開口部の上にシート１１を拡げ、その上から先ず、左側の波形シート止め線１の左方の挿入始端をシート止着溝１０ａ内の一方の溝壁へほぼ平行に当てがう姿勢でシートと共に押し込み、続く台形波の山部の角を他方の溝壁へ向かって押し入れる作業を、該波形シート止め線１の右方の端末部まで繰り返し行う（図１、図６参照）。ここまでの作業は従来技術となんら変わりはない。
本考案に係る実施例１は、次に、前記波形シート止め線１の端末部において１波長相当の長さ部分（符号λ参照）をラップするように、右側の波形シート止め線１’の左方の挿入始端をシート止着溝１０ａ内の一方の溝壁へほぼ平行に当てがう姿勢でシートと共に押し込むことを大きな特徴点とし、続く台形波の山部の角を他方の溝壁へ向かって押し入れる作業を該波形シート止め線１’の右方の端末部まで繰り返し行う。
以後、図示は省略するが、前述した波形シート止め線１’の止着作業と同様の手法で、所要数の波形シート止め線を、１波長相当の長さ部分をラップするように一定方向のシート止め材１０の全長にわたり順次継ぎ足し、もって波形シート止め線の止着構造を実現する。 Specifically, the sheet 11 is spread over the opening of the sheet stopper 10, and from the top, the left insertion start end of the left corrugated sheet stopper line 1 is used as one groove wall in the sheet fixing groove 10a. The operation of pushing together with the sheet in a posture almost parallel to the sheet and pushing the corner of the trapezoidal wave crest toward the other groove wall is repeated until the right end of the corrugated sheet retaining line 1 ( 1 and 6). The work so far is no different from the prior art.
In the first embodiment of the present invention, the left side of the right corrugated sheet retaining line 1 ′ is then wrapped so as to wrap a length portion corresponding to one wavelength (see reference numeral λ) at the terminal portion of the corrugated sheet retaining line 1. The main feature of this is that it is pushed together with the sheet in such a way that the insertion start end of one side is applied to one groove wall in the sheet fixing groove 10a almost in parallel, and the corner of the trapezoidal wave crest is directed to the other groove wall. The pushing operation is repeated until the terminal portion on the right side of the corrugated sheet retaining line 1 ′.
Thereafter, although not shown in the figure, the required number of corrugated sheet retaining lines are arranged in a certain direction so as to wrap a length portion corresponding to one wavelength by the same method as the above-described fixing operation of the corrugated sheet retaining line 1 ′. The sheet stopper material 10 is successively added over the entire length, thereby realizing a structure for fixing the corrugated sheet stopper line.

本実施例１では、先付けした波形シート止め線１の端末部に対し、後付けする波形シート止め線１’の始端部を、重ね合わせることなく１／２波長分だけずらした互い違いの配置（クロス配置）にラップさせて実施している。
前記クロス配置で実施する意義は、後付けする波形シート止め線１’の始端部の山部を、先付けした波形シート止め線１の山部と同様に、シート止め材１０のシート止着溝内の底面部にきっちり嵌め込むことにより、該波形シート止め線１’の止着性（定着性）、ひいては止着構造全体の引張強度を高めるためである。また、ビニルハウス等の農業用温室は、通例２、３年程度のサイクルで老朽化または破損したシート１１の張り替えを行っており、この場合、先ずシート止め線１、１’の端部をシート止め材１０から引き外す必要があるが、クロス配置がマーキングの役割を果たし、スムーズな引き外し作業を実現するためである。 In the first embodiment, a staggered arrangement (cross arrangement) in which the starting end portion of the corrugated sheet retaining line 1 ′ to be retrofitted is shifted by ½ wavelength with respect to the terminal portion of the corrugated sheet retaining line 1 attached in advance. ).
The significance of carrying out by the cross arrangement is that the peak portion of the starting end portion of the corrugated sheet retaining line 1 ′ to be retrofitted is in the sheet fastening groove of the sheet stopper material 10 in the same manner as the peak portion of the corrugated sheet retaining line 1 attached in advance. This is because the corrugated sheet retaining line 1 ′ is firmly fitted into the bottom surface portion, thereby increasing the fastening property (fixing property) and thus the tensile strength of the entire fastening structure. In addition, agricultural greenhouses such as vinyl houses usually renew the aged or damaged sheet 11 in a cycle of about 2 to 3 years. In this case, first, the end of the sheet retaining lines 1 and 1 'is the sheet. This is because the cross arrangement plays a role of marking and realizes a smooth pull-out operation.

なお、本考案に係る止着構造を構成するシート止め材１０、波形シート止め線１、及びシート１１の仕様（形態）については、従来一般の部材が好適に用いられるので詳しい説明は省略する（前記段落［0004］参照）。
ちなみに、本実施例１に係るシート止め材１０は、図６に示したように、カール部１０ｂ、１０ｃが内向きの深型タイプを用いているが、これに限定されず、図１２に示したように、カール部が外向きの浅型タイプでも同様に実施できる。また、本実施例１に係る波形シート止め線１は、ほぼ台形波状タイプ（同一台形が交互に反転して連続するような形状）で実施しているが、これに限定されず、ほぼ半円弧波状タイプ（同一半円弧が交互に反転して連続するような形状）でも同様に実施することができる（例えば、本出願人が先に出願した前記特許文献２を参照）。さらに、止着構造を概略的に示した図１では図示の便宜上、凹溝部１０ｄを省略した。
以下に説明する実施例２〜実施例５についても同様の技術的思想とする。 In addition, about the specification (form) of the sheet | seat stop material 10, the corrugated sheet | seat stop line 1, and the sheet | seat 11 which comprise the fastening structure based on this invention, since a conventional general member is used suitably, detailed description is abbreviate | omitted ( See paragraph [0004] above).
Incidentally, as shown in FIG. 6, the sheet stopper 10 according to the first embodiment uses a deep type in which the curled portions 10 b and 10 c are inward. As described above, the same can be applied to a shallow type with the curled portion facing outward. Further, the corrugated sheet retaining line 1 according to the first embodiment is implemented in a substantially trapezoidal corrugated type (a shape in which the same trapezoid is alternately reversed and continuous), but is not limited thereto, and is substantially a semicircular arc. A wavy type (a shape in which the same semicircular arcs are alternately reversed and continued) can also be implemented in the same manner (see, for example, Patent Document 2 previously filed by the present applicant). Further, in FIG. 1 schematically showing the fastening structure, the concave groove portion 10d is omitted for convenience of illustration.
The same technical idea applies to Examples 2 to 5 described below.

ここで、この実施例１に係る止着構造について、図９に示した引張試験と同様の試験を行った。すなわち、図１に示す止着構造について、幅１００ｃｍの２枚重ねのポリオレフィンシート１１を、端部同士をクロス配置とした波形シート止め線１、１’で均等（符号Ｘ線を境界線として左右）に各５０ｃｍずつシート止め材１０に止着してなる止着構造の引張強度を測定した。
その結果、図１に係る止着構造は、図１１Ａ、Ｂに係る一本物の波形シート止め線１を用いた止着構造と同様に、測定値が４００ｋｇｆ・ｃｍの段階であっても、波形シート止め線１、１’の止着状態に特に変化はなかった。
したがって、実施例１に係る波形シート止め線１、１’の止着構造によれば、部材点数や作業工程を一切増やすことなく、先付けした波形シート止め線１の端末部の止着強度、ひいては当該止着構造全体の引張強度を、前記一本物の波形シート止め線１を用いた止着構造の引張強度に匹敵するほどに高めることができると云える。 Here, the fastening structure according to Example 1 was subjected to the same test as the tensile test shown in FIG. That is, with respect to the fastening structure shown in FIG. 1, two sheets of polyolefin sheet 11 having a width of 100 cm are evenly distributed on corrugated sheet fastening lines 1 and 1 ′ whose ends are arranged in a crossed manner (left and right with the X-ray as a boundary line). The tensile strength of the fastening structure formed by fastening to the sheet stopper 10 by 50 cm each was measured.
As a result, the fastening structure according to FIG. 1 is similar to the fastening structure using the single corrugated sheet fastening line 1 according to FIGS. 11A and 11B even if the measured value is at a stage of 400 kgf · cm. There was no particular change in the fastening state of the sheet fastening lines 1, 1 ′.
Therefore, according to the fastening structure of the corrugated sheet retaining lines 1, 1 ′ according to the first embodiment, the fastening strength of the terminal portion of the corrugated sheet retaining line 1, and thus without any increase in the number of members and work processes, It can be said that the tensile strength of the entire fastening structure can be increased to be comparable to the tensile strength of the fastening structure using the single corrugated sheet fastening line 1.

図２は、本考案に係る波形シート止め線１、１’の止着構造の異なる実施例を示している。
この実施例２に係る止着構造は、上記実施例１と比し、波形シート止め線１、１’の山部の位置をともに上下に逆転（反転）させた点が相違する。
すなわち、この実施例２に係る止着構造は、本実施例１と同様に、先付けした波形シート止め線１の端末部に対し、後付けする波形シート止め線１’の始端部を、重ね合わせることなく１／２波長分だけずらした互い違いの配置（クロス配置）にラップさせて実施していることに変わりはない。よって、作業工程等の説明は重複するので省略する（前記段落［0021］参照）。 FIG. 2 shows different embodiments of the fastening structure of the corrugated sheet fastening lines 1, 1 ′ according to the present invention.
The fastening structure according to the second embodiment is different from the first embodiment in that both the positions of the crests of the corrugated sheet fastening lines 1 and 1 ′ are reversed (reversed) up and down.
That is, in the fastening structure according to the second embodiment, as in the first embodiment, the end portion of the corrugated sheet retaining line 1 ′ to be retrofitted is overlapped with the terminal portion of the corrugated sheet retaining line 1 attached in advance. It is still the same that it is implemented by wrapping in a staggered arrangement (cross arrangement) shifted by ½ wavelength. Therefore, the description of the work process and the like is omitted because it is redundant (see paragraph [0021] above).

この実施例２に係る止着構造についても、図９に示した引張試験と同様の試験を行った。すなわち、図２に示す止着構造について、幅１００ｃｍの２枚重ねのポリオレフィンシート１１を、端部同士をクロス配置とした波形シート止め線１、１’で均等（符号Ｘ線を境界線として左右）に各５０ｃｍずつシート止め材１０に止着してなる止着構造の引張強度を測定した。
その結果、図２に係る止着構造は、図１１Ａ、Ｂに係る一本物の波形シート止め線１を用いた止着構造と同様に、測定値が４００ｋｇｆ・ｃｍの段階であっても、波形シート止め線１、１’の止着状態に特に変化はなかった。
したがって、実施例２に係る波形シート止め線１、１’の止着構造によれば、上記実施例１と同様に、部材点数や作業工程を一切増やすことなく、先付けした波形シート止め線１の端末部の止着強度、ひいては当該止着構造全体の引張強度を、前記一本物の波形シート止め線１を用いた止着構造の引張強度に匹敵するほどに高めることができると云える。 The fastening structure according to Example 2 was also tested in the same manner as the tensile test shown in FIG. That is, with respect to the fastening structure shown in FIG. 2, a two-layer polyolefin sheet 11 having a width of 100 cm is evenly distributed on the corrugated sheet fastening lines 1 and 1 ′ whose ends are arranged in a cross arrangement (left and right with the X-ray as a boundary line). The tensile strength of the fastening structure formed by fastening to the sheet stopper 10 by 50 cm each was measured.
As a result, the fastening structure according to FIG. 2 is similar to the fastening structure using the single corrugated sheet fastening line 1 according to FIGS. 11A and 11B even when the measured value is 400 kgf · cm. There was no particular change in the fastening state of the sheet fastening lines 1, 1 ′.
Therefore, according to the fastening structure of the corrugated sheet retaining lines 1, 1 ′ according to the second embodiment, as in the first embodiment, the corrugated sheet retaining lines 1 that have been attached in advance can be used without increasing the number of members and work steps. It can be said that the fastening strength of the terminal portion and thus the tensile strength of the whole fastening structure can be increased to be comparable to the tensile strength of the fastening structure using the single corrugated sheet fastening line 1.

図３Ａ、Ｂは、本考案に係る波形シート止め線１、１’の止着構造の異なる実施例を示している。
この実施例３に係る止着構造は、上記実施例１、２と比し、先付けした波形シート止め線１の端末部に対し、後付けする波形シート止め線１’の始端部を、上下に重ね合わせた配置でラップさせて実施している点が相違する（図１と図３Ａ、図２と図３Ｂを対比して参照）。ラップ長は、同じく一波長相当の長さ部分（符号λ参照）である。
すなわち、図３Ａ、Ｂに係る止着構造は、上記実施例１、２と比し、後付けする波形シート止め線１’を反転させて止着作業を行う以外は同様の作業工程で実施するのでその説明は省略する（前記段落[0021]参照）。 3A and 3B show different embodiments of the fastening structure of the corrugated sheet fastening lines 1 and 1 'according to the present invention.
In the fastening structure according to the third embodiment, as compared with the first and second embodiments, the end portion of the corrugated sheet retaining line 1 ′ to be retrofitted is overlapped vertically with respect to the terminal portion of the corrugated sheet retaining line 1 attached in advance. It is different in that it is carried out by wrapping in a combined arrangement (see FIG. 1 and FIG. 3A, and FIG. 2 and FIG. 3B in comparison). The wrap length is also a length portion corresponding to one wavelength (see symbol λ).
That is, the fastening structure according to FIGS. 3A and 3B is performed in the same work process as in the first and second embodiments except that the fastening work is performed by inverting the corrugated sheet fastening line 1 ′ to be retrofitted. The description is omitted (see paragraph [0021] above).

この実施例３に係る止着構造についても、図９に示した引張試験と同様の試験を行った。すなわち、図３Ａ、Ｂに示す止着構造について、幅１００ｃｍの２枚重ねのポリオレフィンシート１１を、端部同士を重ね合わせ配置とした波形シート止め線１、１’で均等（符号Ｘ線を境界線として左右）に各５０ｃｍずつシート止め材１０に止着してなる止着構造の引張強度を測定した。
その結果、図３Ａに係る止着構造は、図１１Ａ、Ｂに係る一本物の波形シート止め線１を用いた止着構造と同様に、測定値が４００ｋｇｆ・ｃｍの段階であっても、波形シート止め線１、１’の止着状態に特に変化はなかった。
一方、図３Ｂに係る止着構造も、測定値が４００ｋｇｆ・ｃｍの段階であっても、波形シート止め線１、１’の止着状態に特に変化はなかった。
したがって、実施例３に係る波形シート止め線１、１’の止着構造によれば、上記実施例１、２と同様に、部材点数や作業工程を一切増やすことなく、先付けした波形シート止め線１の端末部の止着強度、ひいては当該止着構造全体の引張強度を、前記一本物の波形シート止め線１を用いた止着構造の引張強度に匹敵するほどに高めることができると云える。 For the fastening structure according to Example 3, the same test as the tensile test shown in FIG. 9 was performed. That is, with respect to the fastening structure shown in FIGS. 3A and 3B, a two-layered polyolefin sheet 11 having a width of 100 cm is evenly aligned with corrugated sheet fastening lines 1 and 1 ′ with end portions arranged in an overlapping manner (boundary reference sign X-rays). The tensile strength of the fastening structure formed by fastening the sheet fastening material 10 by 50 cm to the left and right) was measured.
As a result, the fastening structure according to FIG. 3A is similar to the fastening structure using the single corrugated sheet fastening line 1 according to FIGS. 11A and 11B even if the measured value is 400 kgf · cm. There was no particular change in the fastening state of the sheet fastening lines 1, 1 ′.
On the other hand, even in the fastening structure according to FIG. 3B, there was no particular change in the fastening state of the corrugated sheet fastening lines 1 and 1 ′ even when the measured value was 400 kgf · cm.
Therefore, according to the fastening structure of the corrugated sheet retaining lines 1, 1 ′ according to the third embodiment, the corrugated sheet retaining lines that have been attached in advance without increasing the number of members and the work steps as in the first and second embodiments. It can be said that the fastening strength of the terminal portion of 1 and the tensile strength of the fastening structure as a whole can be increased to be comparable to the tensile strength of the fastening structure using the single corrugated sheet fastening line 1. .

図４Ａ、Ｂは、本考案に係る波形シート止め線１、１’の止着構造の異なる実施例を示している。
この実施例４に係る止着構造は、上記実施例１、２と比し、クロス配置にラップさせて継ぎ足している点は同様であるが、ラップ長を１／２波長（１／２λ）短くして継ぎ足している点、及び、後付けする波形シート止め線１’を反転させて止着作業を行う点が主に相違する。それ以外は同様の作業工程で実施するのでその説明は省略する（前記段落[0021]参照）。 4A and 4B show different embodiments of the fastening structure of the corrugated sheet fastening lines 1, 1 'according to the present invention.
The fastening structure according to the fourth embodiment is similar to the first and second embodiments in that the wrap length is shortened by ½ wavelength (½λ), although the wrap length is similar to that of the first and second embodiments. Thus, the main difference is that the fastening operation is performed by reversing the corrugated sheet retaining line 1 'to be retrofitted. Other than that, since it is carried out in the same work process, its description is omitted (see paragraph [0021] above).

この実施例４に係る止着構造についても、図９に示した引張試験と同様の試験を行った。すなわち、図４Ａ、Ｂに示す止着構造について、幅１００ｃｍの２枚重ねのポリオレフィンシート１１を、端部同士を重ね合わせ配置とした波形シート止め線１、１’で均等（符号Ｘ線を境界線として左右）に各５０ｃｍずつシート止め材１０に止着してなる止着構造の引張強度を測定した。
その結果、図４Ａに係る止着構造は、測定値が３００ｋｇｆ・ｃｍの段階で、右側の波形シート止め線１’の左端部がシート止め材１０から飛び出した。よって、引張強度は、３００ｋｇｆ・ｃｍ程度と考えられる。
一方、図４Ｂに係る止着構造は、測定値が２２０ｋｇｆ・ｃｍの段階で、右側の波形シート止め線１’の左端部がシート止め材１０から飛び出した。よって、引張強度は、２２０ｋｇｆ・ｃｍ程度と考えられる。
したがって、実施例４に係る波形シート止め線１、１’の止着構造は、従来一般に行われている左右に隣接する波形シート止め線１、１’同士を突き合わせた止着構造（図８Ａ、Ｂ参照）と比し、引張強度を高めるとは云えないことが分かった。 The fastening structure according to Example 4 was also tested in the same manner as the tensile test shown in FIG. That is, for the fastening structure shown in FIGS. 4A and 4B, the two-layered polyolefin sheet 11 having a width of 100 cm is evenly aligned with the corrugated sheet fastening lines 1 and 1 ′ with the ends overlapped (between the reference X-rays). The tensile strength of the fastening structure formed by fastening the sheet fastening material 10 by 50 cm to the left and right) was measured.
As a result, in the fastening structure according to FIG. 4A, the left end portion of the corrugated sheet fastening line 1 ′ on the right side jumped out of the sheet fastening material 10 when the measured value was 300 kgf · cm. Therefore, the tensile strength is considered to be about 300 kgf · cm.
On the other hand, in the fastening structure according to FIG. 4B, the left end portion of the corrugated sheet fastening line 1 ′ on the right side jumped out of the sheet fastening material 10 when the measured value was 220 kgf · cm. Therefore, the tensile strength is considered to be about 220 kgf · cm.
Therefore, the fastening structure of the corrugated sheet fastening lines 1 and 1 'according to Example 4 is a fastening structure in which the corrugated sheet fastening lines 1 and 1' adjacent to the left and right, which are generally performed in the related art (FIG. 8A, B)), it was found that the tensile strength cannot be increased.

図５Ａ、Ｂは、本考案に係る波形シート止め線１、１’の止着構造の異なる実施例を示している。
この実施例５に係る止着構造は、上記実施例１、２と比し、ラップ長を１／２波長（１／２λ）短くし、先付けした波形シート止め線１の端末部に対し、後付けする波形シート止め線１’の始端部を、上下に重ね合わせた配置でラップさせて実施している点が相違する（図１と図３Ａ、図２と図３Ｂを対比して参照）。それ以外は同様の作業工程で実施するのでその説明は省略する（前記段落[0021]参照）。 5A and 5B show different embodiments of the fastening structure of the corrugated sheet fastening lines 1, 1 'according to the present invention.
The fastening structure according to the fifth embodiment has a wrap length shorter by ½ wavelength (1 / 2λ) than the first and second embodiments, and is attached later to the terminal portion of the corrugated sheet retaining line 1 that is attached in advance. The difference is that the starting end of the corrugated sheet retaining line 1 ′ is wrapped in an overlapping arrangement (see FIG. 1 and FIG. 3A and FIG. 2 and FIG. 3B in comparison). Other than that, since it is carried out in the same work process, its description is omitted (see paragraph [0021] above).

この実施例５に係る止着構造についても、図９に示した引張試験と同様の試験を行った。すなわち、図５Ａ、Ｂに示す止着構造について、幅１００ｃｍの２枚重ねのポリオレフィンシート１１を、端部同士を重ね合わせ配置とした波形シート止め線１、１’で均等（符号Ｘ線を境界線として左右）に各５０ｃｍずつシート止め材１０に止着してなる止着構造の引張強度を測定した。
その結果、図５Ａに係る止着構造は、図１１Ａ、Ｂに係る一本物の波形シート止め線１を用いた止着構造と同様に、測定値が４００ｋｇｆ・ｃｍの段階であっても、波形シート止め線１、１’の止着状態に特に変化はなかった。
一方、図５Ｂに係る止着構造も、測定値が４００ｋｇｆ・ｃｍの段階であっても、波形シート止め線１、１’の止着状態に特に変化はなかった。
したがって、実施例５に係る波形シート止め線１、１’の止着構造によれば、上記実施例１、２と同様に、部材点数や作業工程を一切増やすことなく、先付けした波形シート止め線１の端末部の止着強度、ひいては当該止着構造全体の引張強度を、前記一本物の波形シート止め線１を用いた止着構造の引張強度に匹敵するほどに高めることができると云える。 The fastening structure according to Example 5 was also subjected to a test similar to the tensile test shown in FIG. That is, in the fastening structure shown in FIGS. 5A and 5B, the two-layer polyolefin sheet 11 having a width of 100 cm is evenly aligned with the corrugated sheet fastening lines 1 and 1 ′ with the end portions arranged in an overlapping manner (the boundary between the reference X-rays). The tensile strength of the fastening structure formed by fastening the sheet fastening material 10 by 50 cm to the left and right) was measured.
As a result, the fastening structure according to FIG. 5A is similar to the fastening structure using the single corrugated sheet fastening line 1 according to FIGS. 11A and 11B even if the measured value is at a stage of 400 kgf · cm. There was no particular change in the fastening state of the sheet fastening lines 1, 1 ′.
On the other hand, in the fastening structure according to FIG. 5B, there was no particular change in the fastening state of the corrugated sheet fastening lines 1 and 1 ′ even when the measured value was 400 kgf · cm.
Therefore, according to the fastening structure of the corrugated sheet retaining lines 1, 1 ′ according to the fifth embodiment, the corrugated sheet retaining lines that have been attached in advance without increasing the number of members and work steps as in the first and second embodiments. It can be said that the fastening strength of the terminal portion of 1 and the tensile strength of the fastening structure as a whole can be increased to be comparable to the tensile strength of the fastening structure using the single corrugated sheet fastening line 1. .

＜考察＞
上記実施例１〜実施例３の試験結果より、先付けした波形シート止め線１の端末部に対し、後付けする波形シート止め線１’の始端部を、１波長（λ）相当の長さ部分ラップさせて継ぎ足す止着構造は、ラップ配置（クロス配置、重ね合わせ配置）に拘わらず、従来一般に行われている左右に隣接する波形シート止め線１、１’同士を突き合わせた止着構造（図８Ａ、Ｂ参照）と比し、止着構造全体の引張強度を飛躍的に高めることができると云える。さらには、一本物の波形シート止め線１を用いた止着構造の引張強度に匹敵するほどに高めることができると云える。
また、上記実施例４と実施例５の試験結果より、先付けした波形シート止め線１の端末部に対し、後付けする波形シート止め線１’の始端部を、１／２波長（１／２λ）相当の長さ部分ラップさせて継ぎ足す止着構造は、重ね合わせ配置（図５参照）で実施することを条件に、従来一般に行われている左右に隣接する波形シート止め線１、１’同士を突き合わせた止着構造（図８Ａ、Ｂ参照）と比し、止着構造全体の引張強度を飛躍的に高めることができると云える。さらには、一本物の波形シート止め線１を用いた止着構造の引張強度に匹敵するほどに高めることができると云える。
なお、図示は省略するが、１波長以上の長さ部分（例えば、２〜３波長）をラップさせて継ぎ足す止着構造は、従来に係る止着構造（図８Ａ、Ｂ参照）と比し、特に説明するまでもなく止着構造全体の引張強度を飛躍的に高めることができるのは明らかである。しかし、ラップ長が長ければ長いほど、その分だけシート止め材１０に止め付ける波形シート止め線１の尺が必要となるので、経済的とは云えない。 <Discussion>
From the test results of Examples 1 to 3 above, the end portion of the corrugated sheet retaining line 1 ′ to be retrofitted is partially overlapped with a length corresponding to one wavelength (λ) with respect to the terminal portion of the corrugated sheet retaining line 1 that has been attached in advance. The fastening structure to be added is a fastening structure in which the corrugated sheet fastening lines 1 and 1 'adjacent to the left and right are generally abutted regardless of the wrap arrangement (cross arrangement or overlapping arrangement) (see FIG. 8A and B), it can be said that the tensile strength of the entire fastening structure can be dramatically increased. Furthermore, it can be said that the tensile strength of the fastening structure using the single corrugated sheet fastening line 1 can be increased.
Further, from the test results of Example 4 and Example 5 described above, the start end portion of the corrugated sheet retaining line 1 ′ to be retrofitted with respect to the terminal portion of the corrugated sheet retaining line 1 that has been attached is ½ wavelength (1 / 2λ). The fastening structure to be joined by wrapping a part of a considerable length is provided on the condition that the corrugated sheet fastening lines 1 and 1 'adjacent to the left and right are generally used on the condition that they are carried out in an overlapping arrangement (see FIG. 5). It can be said that the tensile strength of the entire fastening structure can be drastically increased as compared with the fastening structure (see FIGS. 8A and B). Furthermore, it can be said that the tensile strength of the fastening structure using the single corrugated sheet fastening line 1 can be increased.
In addition, although illustration is abbreviate | omitted, the fastening structure which wraps and adds the length part (for example, 2-3 wavelengths) more than 1 wavelength is compared with the fastening structure (refer FIG. 8A and B) which concerns on the past. Needless to say, it is clear that the tensile strength of the entire fastening structure can be dramatically increased. However, the longer the wrap length is, the more the corrugated sheet retaining line 1 that needs to be secured to the sheet retaining member 10 is necessary, which is not economical.

以上に本考案を図示した実施例に基づいて説明したが、本考案の技術的範囲は、図示した実施例の構成に限定されない。いわゆる当業者が必要に応じて行う設計変更や応用、変形の範囲にまで及ぶことを念のため申し添える。
例えば、図示例に係る波形シート止め線１、１’は、左方から右方へ継ぎ足しているが、もちろん右方から左方へ継ぎ足して実施することもできる。
