Description
【0001】[0001]
この考案は、ビニールハウスの骨組み材とシート止め材とを楔を仲介として連 結する楔式連結具の技術分野に属する。 This invention belongs to the technical field of a wedge-type connecting device that connects a frame material of a greenhouse and a sheet stopper using a wedge as an intermediary.
【0002】[0002]
従来、ビニールハウスの骨組み材とシート止め材とを楔を仲介として連結する 楔式連結具は、一例を図6Aに示したように、その連結具本体1が、ビニールハ ウスの骨組み材2を横断方向に跨ぐコ字形状(及びU字形状を含む、以下同じ) をなし、その両側壁の先端部中央に、シート止め材3と楔4を前記骨組み材2と 直交する方向へ通すに足る大きさ、形状で切り欠き形状をなす開口部5が形成さ れ、同開口部5の口縁部にシート止め材3の両側壁部外面を抱き止める爪部6が 形成されている。 Conventionally, as shown in FIG. 6A, an example of a wedge-type connecting device that connects a frame material of a greenhouse and a sheet stopper using a wedge as an intermediary is that a connecting device body 1 crosses a frame material 2 of a vinyl house. A U-shape (including the U-shape, the same applies hereinafter) that straddles the directions, and is large enough to pass the sheet stopper 3 and the wedge 4 in the direction orthogonal to the framing member 2 at the center of the tip of both side walls. An opening 5 having a cutout shape is formed, and a claw portion 6 for holding the outer surfaces of both side walls of the sheet stopper 3 is formed at the edge of the opening 5.
【0003】 特筆すべきは前記コ字形状をなす連結具本体1の背部1aの中心(力の中心) と前記開口部5の中心(楔力の中心)とは図6A中のa−a線上に位置しほぼ共 通していることである。It should be noted that the center of the back portion 1a (center of force) of the U-shaped connecting member body 1 and the center of the opening 5 (center of wedge force) are on the line aa in FIG. 6A. And are almost common.
【0004】 したがって、楔4を打ち込んでシート止め材3を固定した場合の固定力(楔止 め力)は、楔4が骨組み材2の片面を押す力F1と、連結具本体1の背部1aが 骨組み材2の反対側面を押す力F2とで釣合を保つ構成である。Accordingly, the fixing force (wedge fixing force) when the sheet stopper 3 is fixed by driving the wedge 4 includes a force F 1 for pressing the wedge 4 on one side of the frame member 2 and a back portion of the connecting member body 1. 1a is configured to maintain a balance between the force F 2 to press the opposite sides of the frame member 2.
【0005】[0005]
従って、上記シート止め材3の定着溝へ弾性な止め線7でシート8を止着した 使用状態において、強風時の風圧ないし浮揚力でシート8が矢印T方向の張力で 強く引っ張られた場合、前記F1、F2に起因する骨組み材2との摩擦力よりも 前記張力Tが勝ると、この楔式連結具の取付け位置がずり動き、シート8の張力 が緩むという問題がある。したがって、ビニールハウスの構築における楔4の打 ち込み量のバラツキ、換言すれば前記楔止め力に対応する固定力F1、F2の大 小のバラツキは、重大問題である。Therefore, when the sheet 8 is fixed to the fixing groove of the sheet stopper 3 with the elastic stopper line 7 in the use state, the sheet 8 is strongly pulled by the tension in the direction of the arrow T by the wind pressure or the levitation force at the time of strong wind. If the tension T exceeds the frictional force with the frame member 2 caused by F 1 and F 2 , there is a problem that the mounting position of the wedge-type connecting member shifts and the tension of the seat 8 is loosened. Therefore, the variation of the driving amount of the wedge 4 in the construction of the greenhouse, in other words, the variation of the fixing forces F 1 and F 2 corresponding to the wedge fixing force is a serious problem.
【0006】 特に最近多用されているポリオレフィン系のシートは「こすれ」に弱く、所謂 ハウスバンドで押さえ付けることには適さず、唯一、連結具の固定力に頼ってピ ンとした張力状態に張ることが条件付けられている。その関係上、前記した連結 具の取付け位置がずり動くことは致命的とさえ考えられ、その解決策が急務とさ れている。[0006] In particular, polyolefin-based sheets, which have been widely used recently, are vulnerable to "scratching" and are not suitable for holding down with a so-called house band. It is conditioned. In this connection, it is considered that it is even fatal that the mounting position of the connecting member is shifted, and a solution is urgently needed.
【0007】 また、ビニールハウスの構築に際しては、往々にして作業員が連結具を足場代 わりに使用することも多く、その体重が原因で連結具の取付け位置がずり動くこ とも指摘されている。[0007] Further, when constructing a greenhouse, it is pointed out that workers often use a connecting tool instead of a scaffold, and the mounting position of the connecting tool shifts due to the weight thereof.
【0008】 同じくビニールハウスの構築に際しての問題点を挙げると、構築作業の効率的 な段取りとして、連結具本体は予めシート止め材3の取付け位置(水平横方向の 高さ)に沿って骨組み材2へ予め仮止めしておく。ところが、従来の連結具は仮 止め作用が弱く(又は無いに等しく)、わずかな外力或いは骨組み材の振動など で落下してしまい、それを拾ったり探すことが、かえって面倒になる場合があっ た。[0008] Similarly, when constructing a greenhouse, as an efficient setup of the construction work, the connecting member main body is preliminarily arranged along the mounting position of the sheet stopper 3 (height in the horizontal direction). Temporarily fix to 2 in advance. However, the conventional fasteners have a weak (or no equivalent) temporary fixing action, and fall due to slight external force or the vibration of the framing material. .
【0009】 また、シート止め材3の連結手順として、同シート止め材3の一方の端から他 方に向かって、または両端部から中央に向かって連結具による取付け作業を進め ることが多い。その場合、多くの連結作業は、既にシート止め材3の位置や姿勢 が他の連結具によって固定化された条件で進めるほかないことが多い。しかるに 骨組み材2を跨がせた連結具本体1の開口部4へその口縁部の爪部6を潜らせて 入れ込む為には、シート止め材3を適度に捻り、且つ連結具本体1を回転する操 作(例えば図4を参照)とをうまく組み合わせる必要があるところ、従来の連結 具本体1の構成では背部1aが骨組み材2へ突っかえて回転姿勢に限度があり、 なかなかうまくシート止め材3を開口部4内へその口縁部の爪部6を潜って入れ 込む誘導が難しく、手間がかかり、ひいては作業の能率が悪いという問題点も強 く指摘されている。In addition, as a connection procedure of the sheet stopper 3, an attachment operation using a connector is often performed from one end of the sheet stopper 3 to the other or from both ends to the center. In such a case, it is often the case that many connecting operations must be performed under the condition that the position and the posture of the sheet stopper 3 are already fixed by other connecting members. However, in order to insert the claw portion 6 of the rim into the opening 4 of the connecting member main body 1 over which the frame member 2 is straddled, the sheet stopper 3 is suitably twisted and the connecting member main body 1 is twisted. It is necessary to combine well with the operation of rotating the seat (for example, see FIG. 4). However, in the configuration of the conventional connecting member main body 1, the back portion 1a sticks to the framing member 2 and the rotation posture is limited, so that the seat is not easily formed. It is also strongly pointed out that it is difficult to guide the stopper 3 into the opening 4 by digging into the claw 6 on the edge thereof, which is troublesome, and that the work efficiency is poor.
【0010】 よって本考案の目的は、楔止め力によって骨組み材の両面に発生する力に起因 する上述の作用力F1、F2が偏位して発生し、そのため連結具の取付け状態に 効き勝手を生じ、前記の効き勝手を積極的に応用、利用することにより、シート に発生する張力の大きさ、或いは作業員が足場代わりに利用することに十分耐え て、取付け位置がずり動く心配がなく、ひいては楔を打ち込む量のバラツキ(楔 止め力のバラツキ)がさして問題にならず、ポリオレフィン系シートの使用に好 適な楔式連結具を提供することである。Therefore, an object of the present invention is to generate the above-described acting forces F 1 and F 2 which are caused by the force generated on both sides of the framing material due to the wedge fastening force, which is effective for the attachment state of the connecting tool. By taking advantage of the above-mentioned effectiveness and using it positively, there is a concern that the magnitude of the tension generated in the seat or the worker will be able to withstand the use as a substitute for scaffolding and the mounting position will shift. Accordingly, the present invention is to provide a wedge-type connecting tool suitable for use of a polyolefin-based sheet, which does not cause any problem due to a variation in the amount of driving the wedge (variation in a wedging force).
【0011】 本考案の次の目的は、骨組み材への仮止め効果に優れ、また、シート止め材を 開口部へ入れ込む操作性に優れた構成の楔式連結具を提供することである。[0011] A second object of the present invention is to provide a wedge-type connector having a configuration that has an excellent temporary fixing effect on a frame member and has excellent operability for inserting a sheet stopper into an opening.

【0016】[0016]
図1〜図4は、請求項1記載の考案に係るビニールハウス用の楔式連結具の実 施形態を示している。 1 to 4 show an embodiment of a wedge-type connecting device for a greenhouse according to the invention of claim 1.
【0017】 この楔式連結具の連結具本体10は、ビニールハウスの骨組み材2を横断方向 に跨ぐコ字形状をなし、その両側壁12、12の先端部に、シート止め材3と楔 4を前記骨組み材2と直交する方向へ通すに適切な形状、大きさで切り欠き形状 をなす開口部15がほぼ矩形状に形成されている。更に同開口部15の口縁部に 、シート止め材3の両側壁外面を抱き止める爪部16、16が形成された構成で ある。骨組み材2の横断面が円形であると必然的に連結具本体10がU字形状と なるが、前記コ字形状に含めた考え方である。The connecting member body 10 of the wedge-type connecting member has a U-shape that straddles the frame member 2 of the greenhouse in the transverse direction, and has sheet stoppers 3 and wedges 4 at the distal ends of both side walls 12, 12. The opening 15 is formed in a substantially rectangular shape having a notch shape with a shape and a size suitable for passing the material in a direction orthogonal to the frame material 2. Further, at the edge of the opening 15, claw portions 16, 16 for holding the outer surfaces of both side walls of the sheet stopper 3 are formed. If the cross section of the framework 2 is circular, the connector body 10 necessarily has a U-shape.
【0018】 前記コ字形状をなす連結具本体10の側壁12は、図2で明らかなように、両 側壁12、12の背部11に近い両縁に平行な斜辺部13、13を形成して、全 体として菱形に形成されている。そして、背部11は、前側の斜辺部13の終端 から約20mm位の範囲W(図1を参照)を平行に切除した形状とされている。As shown in FIG. 2, the side wall 12 of the connector main body 10 having the U-shape forms oblique sides 13, 13 parallel to both edges near the back 11 of the side walls 12, 12. Are formed in a diamond shape as a whole. The back portion 11 has a shape in which a range W (see FIG. 1) of about 20 mm from the end of the oblique side portion 13 on the front side is cut in parallel.
【0019】 したがって、この連結具本体10の使用状態を示す図2で明らかなように、前 記開口部15へ挿入した楔4の楔止め力F1の中心(開口部15の中心とほぼ一 致する。)と、背部11が前記楔止め力F1の反力として骨組み材2の反対側面 を押す力F2の中心(背部11の中心とほぼ一致する。)とが一定の寸法eだけ 偏位した形状となっている。前記偏位量eの大きさは自由に設計されるが、基本 的には、当該連結具本体10でビニールハウスの骨組み材2と直交する配置のシ ート止め材3を図4のように開口部15の爪部16の内側へ誘い込む際に必要な 範囲wの背部を切除することが、大きな設計要因となる(請求項2記載の考案) 。Therefore, as is apparent from FIG. 2 showing the use state of the connecting member main body 10, the center of the wedge fixing force F 1 of the wedge 4 inserted into the opening 15 (substantially equal to the center of the opening 15). match. a), the back 11 substantially coincides with the center of the wedging force center of force F 2 to press the opposite sides of the frame member 2 as a reaction force of F 1 (back 11.) and only certain dimensions e It has a deviated shape. Although the magnitude of the deviation amount e is freely designed, basically, the seating member 3 arranged orthogonally to the frame member 2 of the greenhouse in the connecting member body 10 as shown in FIG. A significant design factor is to cut off the back part of the area w necessary for guiding the inside of the claw part 16 of the opening part 15 (the invention according to claim 2).
【0020】 図1の範囲Wを切除された背部11は、図4のように連結具本体10が骨組み 材2を跨いでシート止め材3を開口部15へ誘い込むにあたり、前記範囲Wの分 だけ骨組み材2へ突き当たるまでの回転角を大きくとれ、シート止め材3の誘い 込み作業が楽である。つまり、前記誘い込み作業だけを考えると、前記範囲Wは 大きいほど好ましいのである。The back portion 11 from which the range W in FIG. 1 has been cut out has a length corresponding to the range W when the connector body 10 guides the sheet stopper 3 into the opening 15 across the frame member 2 as shown in FIG. A large rotation angle until it comes into contact with the frame member 2 can be taken, and the work of inviting the sheet stopper 3 is easy. That is, considering only the invitation work, the larger the range W, the better.
【0021】 しかも、前記楔止め力F1の中心と、その反力として押す力F2の中心とが偏 位した構成であるがために、図2のように止め線7で止着したシート8に風圧又 は浮揚力による張力Tが大きく作用した場合には、偏位量eに起因する反時計回 り方向の回転力を増幅する結果となり、つまり連結具本体10をこじる形となり 、前記の力F1、F2に原因する摩擦力が増大して、連結具の位置ズレを防ぐ作 用効果をもたらす。要するに効き勝手を発揮するのである。Moreover, since the center of the wedge fixing force F 1 and the center of the pressing force F 2 as the reaction force are deviated from each other, the sheet fixed by the fixing line 7 as shown in FIG. When the tension T due to the wind pressure or the levitation force acts on the motor 8, the counterclockwise rotation force caused by the displacement amount e is amplified, that is, the connecting member main body 10 is prying. The frictional force caused by the forces F 1 and F 2 increases, and an effect of preventing the displacement of the connecting tool is brought about. In short, it is effective.
【0022】 したがって、ビニールハウスの構造上、シート8に対する風圧、浮揚力が特に 大きく発生する部分には、この連結具を図2の態様で使用すると、位置ズレ防止 に効果的である。また、シートを押さえるハウスバンドを使用できないポリオレ フィン系シートによるビニールハウスの構築にすこぶる好適である。Therefore, in a portion where the wind pressure and the levitation force on the sheet 8 are particularly large due to the structure of the greenhouse, the use of the connecting tool in the mode shown in FIG. 2 is effective in preventing the displacement. Further, it is very suitable for constructing a greenhouse using a polyolefin-based sheet in which a house band for holding the sheet cannot be used.
【0023】 連結具本体10の両側壁12には、ビニールハウスの骨組み材2へ跨らせた際 に同骨組み材2の両側面を挟み付けて止まる仮止め部14が、内方への打ち出し 加工突起として形成されている(請求項3記載の考案)。On both side walls 12 of the connecting member main body 10, a temporary fixing portion 14 that sandwiches and stops both side surfaces of the framed material 2 when straddling the framed material 2 of the greenhouse is punched inward. It is formed as a processed projection (the invention according to claim 3).
【0024】 したがって、図3に示したように、スリット2aを有する開放断面形状で、両 側面がスリット2aに向かって撓み易い骨組み材2であっても、仮止め部14に よる仮止め効果を十分に発揮する。骨組み材2が円形断面の金属パイプである場 合には、必然的に連結具本体はU字形状とされるので、仮止め部14は、同パイ プの横断面において180゜を少し超えた位置に設けることにより、同様の作用 効果を得ることができる。仮止め部14は、突起構造に限らず、連結具本体10 の背部11或いは側壁12の一部分を片持ちバネ形式に打ち起こした構造で実施 することができる。しかも前記仮止め部14を設ける位置は、図1のように骨組 み材2の側面へ当たる範囲の位置のほか、便宜上図6A、Bに示したように、骨 組み材2へ両側壁12が完全に跨った状態で丁度抜け止め作用を奏する位置に片 持ちバネ形式の仮止め部14’を設けることも実施される。Therefore, as shown in FIG. 3, even if the frame 2 has an open cross-sectional shape having the slit 2 a and both sides are easily bent toward the slit 2 a, the temporary fixing effect by the temporary fixing portion 14 can be obtained. Demonstrate fully. When the frame member 2 is a metal pipe having a circular cross section, the connecting member body is inevitably U-shaped, so that the temporary fixing portion 14 slightly exceeds 180 ° in the cross section of the pipe. By providing it at the position, the same function and effect can be obtained. The temporary fixing portion 14 is not limited to the protrusion structure, and may be implemented by a structure in which a part of the back portion 11 or the side wall 12 of the connecting member main body 10 is raised in a cantilever spring type. Further, the position where the temporary fixing portion 14 is provided is not only a position in a range where the temporary fixing portion 14 is in contact with the side surface of the frame member 2 as shown in FIG. 1, but also, as shown in FIGS. It is also practiced to provide a cantilever spring type temporary fixing portion 14 ′ at a position where the retaining action is exactly exerted when completely straddling.
【0025】 更に、コ字形状又はU字形状をなす連結具本体10の背部11に小さなU字形 状の折曲げ部を形成して、両側壁が内方へ向かってバネ性を発揮する構成、或い は両側壁が骨組み材2の外径寸法よりも若干小さくて、ビニールハウスの骨組み 材を弾力的に挟み付ける形状で実施することもできる(請求項4記載の考案)。Further, a small U-shaped bent portion is formed on the back portion 11 of the connecting member main body 10 having a U-shape or a U-shape so that both side walls exhibit inward spring characteristics. Alternatively, it is also possible to implement the present invention in a shape in which both side walls are slightly smaller than the outer diameter of the frame material 2 so that the frame material of the greenhouse is elastically sandwiched between them.
【0026】 上記のように連結具本体10が仮止め部14を備えているため、これを骨組み 材2のシート止め材取付け位置の近傍へ仮止めして準備することにすこぶる好都 合で、作業能率を高めることができる。Since the connecting member main body 10 is provided with the temporary fixing portion 14 as described above, it is extremely convenient to temporarily fix the temporary fixing portion 14 in the vicinity of the position where the sheet fixing member is attached to the frame member 2. Work efficiency can be improved.
【0027】 次に図5は、上記と同じ構成の連結具本体10を、図2とは正反対の態様で使 用した使用例を示している。これはビニールハウスの構築又はメンテナンス(シ ートの張り替えその他)において、作業者が足場代わりに連結具の上に足を乗せ ても、その人の体重その他の負荷Pに十分耐える使用態様であることを示してい る。Next, FIG. 5 shows a usage example in which the connector main body 10 having the same configuration as described above is used in a mode opposite to that of FIG. This is a mode of use that can withstand the weight and other loads P of the person even when the worker puts his foot on the connecting device instead of the scaffold in the construction or maintenance of the greenhouse (replacement of the sheet, etc.). It is shown that.
【0028】 すなわち、上述したように楔止め力F1の中心と、その反力として骨組み材2 を押す力F2の中心とがeだけ偏位した構成である。しかも楔止め力F1の中心 が骨組み材2を押す力F2の中心よりも下位に位置する使用態様であるため、図 5のように負荷Pが作用すると、偏位量eに起因する反時計回り方向の回転力を 増幅する結果となる。つまり連結具本体10をこじる形となり、前記の力F1、 F2に起因する摩擦力が増大して位置ズレを防ぐ作用効果をもたらす。要するに 効き勝手を発揮するのである。That is, as described above, the center of the wedge fixing force F 1 and the center of the force F 2 that pushes the frame material 2 as the reaction force are displaced by e. Moreover, since the center of the wedging force F 1 is a usage mode positioned below the center of the force F 2 pushing the framework member 2, the load P acts as in Figure 5, anti due to deviation amount e This results in amplifying the clockwise rotational force. In other words, the connecting member main body 10 is pryed, and the frictional force resulting from the forces F 1 and F 2 increases to provide an effect of preventing displacement. In short, it is effective.
【0029】 したがって、ビニールハウスの構造上、作業者が足場代わりに連結具の上に足 を乗せるケースの多い部分では、図5の使用態様(効き勝手)で使用すると、位 置ズレ防止に効果的で、ビニールハウスの構造に支障をきたさないから、好都合 である。Therefore, in a part of the structure of the greenhouse where the worker often puts his foot on the connecting tool instead of the scaffold, when used in the mode of use shown in FIG. This is convenient because it does not hinder the structure of the greenhouse.
【0030】[0030]
請求項1〜4に記載した考案に係る楔式連結具は、楔止め力によって骨組み材 の両面に発生する力(上述の作用力F1、F2)が偏位して発生する構成なので 、当該連結具の取付け状態に効き勝手を生じ、その効き勝手を積極的に応用、利 用することにより、例えばシートに発生する張力の大きさ、或いは作業員が足場 代わりに利用することに十分耐えて、取付け位置がずり動く心配がない。したが っては楔を打ち込む量のバラツキ(楔止め力のバラツキ)がさして問題にならず 、ビニールハウス構築の品質が一定し、作業性が向上し、シートを押さえ付ける ハウスバンドを使用できないポリオレフィン系シートを使用するビニールハウス の構築に好適である。The wedge-type connecting device according to the invention described in claims 1 to 4 has a configuration in which the forces (the above-described acting forces F 1 and F 2 ) generated on both surfaces of the framing material due to the wedge fixing force are generated in a deviated manner. Properly used in the installation state of the connecting device, and by actively applying and utilizing the effect, for example, the magnitude of the tension generated in the seat, or sufficient durability for workers to use it as a scaffold There is no need to worry about the mounting position shifting. Therefore, variations in the amount of wedges driven (variations in the wedging force) do not cause a problem, and the quality of the greenhouse construction is constant, workability is improved, and the sheet is pressed down. It is suitable for building greenhouses that use system sheets.
【0031】 また、この楔式連結具は、骨組み材への仮止め効果に優れ、また、シート止め 材を開口部へ入れ込む操作性に優れた構成なので、やはりビニールハウス構築の 作業性向上に大きく貢献するのである。Further, the wedge-type connecting device is excellent in the effect of temporarily fixing the frame material, and is excellent in the operability of inserting the sheet stopping material into the opening, so that the workability of the greenhouse construction is also improved.
