Description

この発明は、温室を覆う膜材であるビニルシートやポリオレフィンシート等（以下、単にシートと云う。）を骨組み材へ止着するためのシート定着用溝形材、特にシート定着用溝が２本平行して一体形成されたダブル型シート定着用溝形材を、長手方向に一連に突き合わせて接続でき、長尺材として使用する接続構造の技術分野に属し、更に云うと、シート定着用溝形材の一端部を絞り加工して雄ジョイント部に成形したダブル型シート定着用溝形材の接続構造に関する。   The present invention relates to a sheet fixing channel for fixing a vinyl sheet, a polyolefin sheet or the like (hereinafter simply referred to as a sheet), which is a film material covering a greenhouse, to a frame material, in particular, two sheet fixing grooves. It belongs to the technical field of connection structure that can be connected as a series of double-type sheet fixing groove members formed in parallel in the longitudinal direction, and is used as a long material. The present invention relates to a connection structure for a double-type sheet fixing channel member formed by drawing one end of a material into a male joint.

従来、所謂ビニルハウスの構築に際し、被覆材であるシートをハウス骨組み材へ止着する手段として、ビニルハウスの骨組に設置される、開口部が幅狭のシート定着用溝を有するシート定着用溝形材が広く知られ実用に供されている。
通例のシート定着用溝形材は、シート定着用溝が一つのシングルタイプであるが、近年、側面や屋根面に空気層を設けるためにシートを二重張りにしたり、シートの上面に遮光ネットシート及び／又は防虫ネットを張るなど、複数のシート材を重複して張る必要性が高くなり、二つのシート止着用溝を連結片により長手方向に２本平行するように一体形成したダブル型シート定着用溝形材も多く使用されている。 Conventionally, when a so-called vinyl house is constructed, a sheet fixing groove having a sheet fixing groove having a narrow opening is installed in the frame of the vinyl house as a means for fixing a sheet as a covering material to the house frame material. Profiles are widely known and put into practical use.
The usual sheet fixing groove shape is a single type with one sheet fixing groove. However, in recent years, the sheet has been doubled to provide an air layer on the side surface or roof surface, or a light shielding net is provided on the upper surface of the sheet. There is a high need to stretch a plurality of sheet materials, such as a sheet and / or insect net, and two double-sheets are integrally formed so that two sheet fastening grooves are parallel to each other in the longitudinal direction by connecting pieces. Many fixing grooves are also used.

いずれのシート定着用溝形材であれ、トラック輸送では長尺物の輸送が敬遠される関係上、２ｍ〜６ｍ程度の長さに定寸切断したシート定着用溝形材が多く市販されている。ビニルハウスの棟の長さは通例５０ｍとか１００ｍなので、前記定尺物のシート定着用溝形材は、長手方向に一連に突き合わせ接続して必要な長さとした上で使用されるのが普通で、現場におけるシート定着用溝形材の接続作業の重要性が増している。   For any sheet fixing groove, any sheet fixing groove that has been cut to a length of about 2 m to 6 m is commercially available because the transportation of long objects is avoided in truck transportation. . The length of a vinyl house ridge is usually 50m or 100m, so the sheet-fixing groove material of the above-mentioned standard is usually used after abutting and connecting in series in the longitudinal direction to the required length. In addition, the importance of connecting the sheet fixing groove material in the field is increasing.

上記シート定着用溝形材の接続構造としては、下記の特許文献１に、シート定着用溝の一端部を絞り加工して本来の横断面形状の肉厚分だけ縮小した雄ジョイント部を形成し、他のシート定着用溝形材の本来形状の端部の内側へ差し込み突き合わせ接続することを可能にした接続技術が記載されている。   As a connection structure for the sheet fixing groove shape material, a male joint portion is formed in the following Patent Document 1 by drawing one end portion of the sheet fixing groove to reduce the thickness of the original cross-sectional shape. In addition, there is described a connection technique that enables insertion and butt connection to the inside of the end portion of the original shape of another sheet fixing groove.

また、ダブル型シート定着用溝形材についても、その接続構造として、下記の特許文献２には、図８Ａ、Ｂに示すように、ダブル型シート定着用溝形材７０の一端部に、端部から接続に必要な長さ範囲にわたり、２本のシート定着用溝７１、７１の横断面形状が本来の横断面形状の肉厚分だけ小さい形状に絞り加工された雄ジョイント部Ｊが形成された接続構造が開示されている。
実用新案登録第３０３５１４２号公報 意匠登録第１０９５３３９号公報 Further, as for the connection structure of the double-type sheet fixing groove member, as shown in FIG. 8A and FIG. 8B, as shown in FIG. A male joint portion J is formed in which the cross-sectional shape of the two sheet fixing grooves 71, 71 is drawn to a shape that is smaller by the thickness of the original cross-sectional shape over the length range necessary for connection from the portion. A connection structure is disclosed.
Utility Model Registration No. 3035142 Design Registration No. 1095339

上述した特許文献１及び特許文献２は、いずれも本出願人の提案に係るもので、雄ジョイント部のシート定着用溝と、接続される他のシート定着用溝形材のシート定着用溝が略同形の横断面形状で、接続部において内外二重にぴったり密着した状態で重なり合い、互いを拘束し合うので、接続の強度及び剛性が十分に大きいし、シート定着用溝が連続するので、シートの止着構造も連続する。その上、前記接続部の横断面外形は、本来のシート定着用溝形材の横断面形状そのものであるから、接続部の外側にパイプジョイント等の在来部品類を使用することに一切支障がないという利点がある。   Patent Document 1 and Patent Document 2 described above both relate to the proposal of the present applicant, and the sheet fixing groove of the male joint portion and the sheet fixing groove of another sheet fixing groove member to be connected are provided. It has a substantially identical cross-sectional shape, and overlaps in a state of being closely attached to the inner and outer doubles at the connecting part and restrains each other, so that the strength and rigidity of the connection are sufficiently large, and the sheet fixing groove is continuous. The fastening structure is continuous. In addition, since the cross-sectional profile of the connecting portion is the cross-sectional shape of the original sheet fixing channel, the use of conventional parts such as pipe joints on the outside of the connecting portion is completely obstructed. There is no advantage.

しかしながら、上記の接続構造は、シングルタイプのシート定着用溝形材の場合は容易に実施（製造）できるが、上記特許文献２に示した、シート定着用溝が２本平行に一体化されたダブル型シート定着用溝形材の場合は、実施（製造）に技術上の問題点がある。   However, the above connection structure can be easily implemented (manufactured) in the case of a single type sheet fixing groove, but the two sheet fixing grooves shown in Patent Document 2 are integrated in parallel. In the case of a double-type sheet fixing channel, there is a technical problem in implementation (manufacturing).

即ち、ダブル型シート定着用溝形材の一端部を図８Ａ、Ｂに示すような雄ジョイント部Ｊに成形する方法としては、いわゆるロールフォーミング加工法で無限長に連続して生産されるダブル型シート定着用溝形材７０は、とりあえず運搬に適した長さに単純切断し、その上で、別途用意したプレス成形機を使用して、図８Ｂに示すように、シート定着用溝７１の両内側の側壁７４を両外側の側壁７５と同様に絞り加工するべく、先ず連結片７２を、二つの溝底壁７３、７３の外径部間の幅寸Ｗだけ切断し、残存する連結片を内側へ折り返してカール部７４ａ（点線部）を成形し、且つ絞り加工を行うほかない。したがって、上記ダブル型シート定着溝形材の接続構造を実現するには、単純切断と、絞り加工の二種類の金型を用意し、二つの作業工程で行うほかない。その故に要する人員も増え、設備投資費用や人件費等が相当に嵩み、シート定着用溝形材一本当たりの単価が当然高くなる。現在、シート定着用溝形材の市場は、メートル単位での価格競争が激しく行われていることから、上記製造方法を実施（製造）することは市場経済の面から排斥され、もっと製造が容易で安価な接続構造が要望されている。   That is, as a method of forming one end portion of the double-type sheet fixing groove shape into a male joint portion J as shown in FIGS. 8A and 8B, a double type continuously produced in an infinite length by a so-called roll forming method. The sheet fixing groove 70 is simply cut into a length suitable for transportation for the time being, and then, using a separately prepared press molding machine, as shown in FIG. In order to draw the inner side wall 74 in the same manner as the outer side walls 75, first, the connecting piece 72 is cut by the width W between the outer diameter portions of the two groove bottom walls 73 and 73, and the remaining connecting piece is removed. The curled portion 74a (dotted line portion) is formed by folding back inward, and drawing is performed. Therefore, in order to realize the connection structure of the double-type sheet fixing groove member, two types of molds, simple cutting and drawing, are prepared and performed in two work steps. Therefore, the number of personnel required increases, and the capital investment cost and labor cost increase considerably, so that the unit price per sheet fixing groove is naturally high. Currently, the market for sheet fixing channel materials is fiercely price-competitive in units of meters, so implementing (manufacturing) the above manufacturing method is rejected from the market economy aspect, making it easier to manufacture. And an inexpensive connection structure is demanded.

本発明の目的は、ダブル型シート定着用溝形材の定寸切断と絞り加工による雄ジョイント部の成形をワンプレス工程で安価に迅速に行える接続構造を提供することであり、生産効率に優れ、更に接続作業やシート定着作業等を簡便に行えるダブル型シート定着用溝形材の接続構造を提供することにある。   It is an object of the present invention to provide a connection structure that can quickly and inexpensively form a male joint part by fixed-size cutting and drawing of a double-type sheet fixing groove material, and is excellent in production efficiency. Another object of the present invention is to provide a connecting structure for a double-type sheet fixing groove member that can easily perform a connecting operation, a sheet fixing operation, and the like.

本発明に係るダブル型シート定着用溝形材の接続構造を、図面に示した実施例に基づいて説明する。
図１は、長手方向に一連に接続するべき２本のダブル型シート定着用溝形材１、１を接続する直前の状態で示している。
このダブル型シート定着用溝形材１の構成は既に周知の通り、溝底壁３と両側壁４、４で形成する開口部が横断面が幅狭のシート定着用溝２を有し、二つのシート定着用溝２が中間連結片５によって長手方向に２本平行するように一体形成されている。前記両側壁４、４の上端は外向きに折り返したカール部４ａ、４ａに構成されており、両内側の側壁４の上端部同士が中間連結片５により連結されている。 The double sheet fixing groove connecting structure according to the present invention will be described based on the embodiments shown in the drawings.
FIG. 1 shows a state immediately before connecting two double-type sheet fixing groove members 1 and 1 to be connected in series in the longitudinal direction.
As already known, the double sheet fixing groove 1 has an opening formed by the groove bottom wall 3 and the side walls 4 and 4 having a sheet fixing groove 2 having a narrow cross section. Two sheet fixing grooves 2 are integrally formed by the intermediate connecting piece 5 so as to be parallel to the longitudinal direction. The upper ends of the side walls 4, 4 are configured as curled portions 4 a, 4 a that are turned outward, and the upper ends of the inner side walls 4 are connected by an intermediate connecting piece 5.

前記ダブル型シート定着用溝形材１は使用上に適切な長さに定寸断されており、その一端部は、単純切断しただけで、本来の横断面形状（図５の外側部分の形状）を有する雌ジョイント部１ａとされている。
同ダブル型シート定着用溝形材１の他端部は、図１と図３Ａ、Ｂに詳示するように、二つのシート定着用溝２を形成する内側の側壁４及び溝底壁３の一部が、中間連結片５と共に、端部から突き合わせ接続に必要とされる長さ範囲Ｌ（約３０〜５０ｍｍ位）にわたり、前記中間連結片５の外幅位置即ち、中間連結片５の両端から側壁４へと変化する湾曲外面から真下に引いた垂線Ｙ、Ｙ間の幅Ｗが垂直に切断されている。 The double-type sheet fixing groove 1 is cut to a suitable length for use, and one end of the double-type sheet fixing groove 1 is simply cut to obtain the original cross-sectional shape (the shape of the outer portion in FIG. 5). It is set as the female joint part 1a which has.
As shown in detail in FIGS. 1 and 3A and 3B, the other end portion of the double-type sheet fixing groove 1 is formed on the inner side wall 4 and the groove bottom wall 3 forming the two sheet fixing grooves 2. part, together with the intermediate connection piece 5, over a length range required for butt connection from the end L (about 30~50mm position), the outer width position of the intermediate connecting piece 5 that is, both ends of the intermediate connection piece 5 The width W between the vertical lines Y and Y drawn straight down from the curved outer surface that changes from the side wall 4 to the side wall 4 is cut vertically.

そして、前記長さ範囲Ｌに残存する両外側の側壁４とカール部４ａ及び溝底壁３の横断面形状が、本来の横断面形状から少なくとも肉厚分相当だけ絞られて小断面に形成されている。
更に、シート定着用溝２の外側の側壁４のカール部４ａは接続に支障がないよう若干押し潰された形状に絞り加工されて雄ジョイント部６が形成されている。
上記の通り、本発明の接続構造を構成する雄ジョイント部６は、シート定着用溝２の両内側の側壁４と溝底壁３の一部を中間連結片５と共に垂線Ｙ−Ｙ間の幅Ｗ部分だけ切断するから、上下のプレス金型は垂直な単純動作で切断化工（シャーリング）を行える。したがって、ロールフォーミング加工法で無限長に曲げ成形したダブル型シート定着用溝形材１を、運搬に適した２ｍ〜６ｍの長さに定尺切断すると同時に、前記内側の側壁４と溝底壁３の一部及び中間連結片５の切断並びに外側の側壁４及びカール部４ａの絞り加工とを所謂ワンプレス工程で加工でき雄ジョイント部６を成形できる。 Then, the lateral cross-sectional shapes of the outer side wall 4 and the curl portion 4a and the groove bottom wall 3 remaining in the length range L are narrowed by at least the thickness corresponding to the original cross-sectional shape to form a small cross-section. ing.
Further, the curled portion 4a of the outer side wall 4 of the sheet fixing groove 2 is drawn into a slightly crushed shape so as not to hinder the connection, so that a male joint portion 6 is formed.
As described above, the male joint portion 6 constituting the connection structure of the present invention has the width between the vertical lines Y and Y along the side wall 4 and the bottom wall 3 on both inner sides of the sheet fixing groove 2 together with the intermediate connecting piece 5. Since only the W portion is cut, the upper and lower press dies can be cut (sheared) by a simple vertical motion. Therefore, the double-type sheet fixing groove 1 bent to an infinite length by the roll forming method is cut to a length of 2 to 6 m suitable for transportation, and at the same time the inner side wall 4 and the groove bottom wall. 3 of the drawing of the part and the cutting of the intermediate coupling piece 5 and the outer side wall 4 and the curled portion 4a can be processed in a so-called one-pressing process can be molded male joint portion 6.

上記のように成形された雄ジョイント部６を有するダブル型シート定着用溝形材１は、一方の雄ジョイント部６を他方の雌ジョイント部１ａの内側へ差し込むことにより、図４のように一連の構造に接続できる。両溝形材１、１の接続部は二つのシート定着用溝２、２の外側の側壁と溝底壁とが内外二重に密着した状態で重なり合い一連に強固に接続される。その際、図５に示すように、絞り加工された雄ジョイント部６の側壁４’の外側のカール部４ａ’、４ａ’は本来の形状のカール部４ａ、４ａの内側に入り込んで同溝２内へ拘束され、前記重なり合う接続部の雄ジョイント部６の内側の側壁４’と溝底壁３の一部は切断されて存在しないため、その肉厚分だけシート定着用溝２内のふところが広くなり、シート止め材が止め易くなる。   The double-type sheet fixing channel member 1 having the male joint portion 6 formed as described above is inserted into the inside of the other female joint portion 1a by inserting one male joint portion 6 into a series as shown in FIG. Can be connected to any structure. The connecting portions of the two groove-shaped members 1 and 1 overlap each other in a state where the outer side wall and the groove bottom wall of the two sheet fixing grooves 2 and 2 are in close contact with each other, and are firmly connected in series. At that time, as shown in FIG. 5, the curled portions 4a ′ and 4a ′ outside the side wall 4 ′ of the drawn male joint portion 6 enter the inside of the original shaped curled portions 4a and 4a, and the groove 2 Since the inner side wall 4 ′ and the groove bottom wall 3 of the male joint portion 6 of the overlapping connecting portion are constrained inward and are not partly cut, there is a space in the sheet fixing groove 2 corresponding to the thickness thereof. It becomes wide and it becomes easy to stop the sheet stopper.

本実施例のダブル型シート定着用溝形材１は、１本のダブル型シート定着用溝形材１の一端部に雄ジョイント部６を形成し、他端部は単に切断しただけの雌ジョイント部１ａに形成して実施するのが通例であるが、この限りではない。１本のダブル型シート定着用溝形材１の両端部を前記雄ジョイント部６、６に形成し、別異のダブル型シート定着用溝形材１の両端部は単に切断しただけの雌ジョイント部１ａ、１ａに形成し、両タイプの溝形材１、１を組み合わせて接続する方法も実施可能である。   The double-type sheet fixing channel 1 of this embodiment has a male joint portion 6 formed at one end of one double-type sheet fixing channel 1 and the other end simply cut by a female joint. Although it is customary to form the part 1a and implement it, this is not restrictive. Both ends of one double-type sheet fixing channel 1 are formed in the male joints 6 and 6, and both ends of another double-type sheet fixing channel 1 are simply cut. A method of forming the portions 1a and 1a and connecting both types of the groove members 1 and 1 in combination is also possible.

なお、上記雄ジョイント部６における溝底壁３、溝側壁４及びカール部４ａの先端部は、雌ジョイント部１ａへの差し込みを容易にするため前方へ細まるように強く絞られた誘導部７（図３Ａの点線に示す）に形成した構成で実施することも好ましい。斯くすると、一連に接続するべき差し込み作業に便利である。 It should be noted that the leading end portions of the groove bottom wall 3, the groove side wall 4 and the curl portion 4a in the male joint portion 6 are strongly squeezed so as to narrow forward so as to facilitate insertion into the female joint portion 1a. It is also preferable to implement with the configuration formed in (shown by the dotted line in FIG. 3A). This is convenient for insertion work to be connected in series.

本発明が実施されるダブル型シート定着用溝形材１のシート定着用溝２の形状、構造は、図１〜図５に示した限りではない。例えば、図６Ａ、Ｂに示したように深型のダブル型シート定着用溝形材１０の一端部を端部から接続に必要な長さ範囲にわたり、上述したと同様の構造に絞り加工をして雄ジョイント部６０を形成し、接続するべき同形状のダブル型シート定着溝形材１０の雌ジョイント部１０ａ内へ差し入れて接続する構成でも実施可能である。また、図７に示すように、図６Ａ、Ｂと略同形であり、その側壁が内側へ若干傾斜した横断面形状とされたダブル型シート定着用溝形状１１に同様に実施することも好適に実施される。   The shape and structure of the sheet fixing groove 2 of the double sheet fixing groove member 1 in which the present invention is implemented are not limited to those shown in FIGS. For example, as shown in FIGS. 6A and 6B, one end of the deep double-type sheet fixing groove 10 is drawn to the same structure as described above over the length range necessary for connection from the end. Alternatively, the male joint portion 60 can be formed and inserted into the female joint portion 10a of the double sheet fixing groove 10 having the same shape to be connected.
