[Prior art]

 Conventionally, in a greenhouse for plant cultivation, a large number of arch pipes are sequentially arranged side by side in the depth direction with a predetermined gap, and a plurality of straight pipes (horizontal pipes) orthogonal to these are arranged inside them. Are arranged in the depth direction, the intersections are firmly connected to assemble the structural aggregate, and a vinyl sheet is stretched on the outer side to cover the structural aggregate. In addition, the sheet is easily damaged by the effects of wind, so many sheet restraints, for example vinyl restraints, are applied to restrain the sheet in order to increase its resistance. .

The above-mentioned seat restraint string is usually attached in the same direction as the arch pipe and one between each arch pipe, and both ends thereof are connected to the legs of the arch pipe group on both sides. It is tied to each side horizontal pipe. In addition, this restraint string is tightened inwardly in the house so as to hold the seat more stably, so that part of the seat is easily attached to the horizontal pipe, especially the shoulder horizontal pipe at the top of the house. Contact was inevitable.

[0004]

[Issues to be solved by the device]

 In such a house, the condensed water generated on the inner surface of the vinyl sheet above the shoulder horizontal pipe gathers on the restraint string while flowing down the inner surface of the sheet, and is transferred to the contact shoulder horizontal pipe. Then, there was the inconvenience of dripping from that part into the house and damaging the cultivated plants. This condensate spillage phenomenon frequently occurs in the shoulder lateral pipes on both sides of the upper part of the house, so it may damage plants at about twice the number of arch pipes or more and cause root rot. Therefore, the damage is extremely large. In the actual situation of such a greenhouse, a dropless connection method has been required to eliminate the phenomenon of condensed water spillage.

However, while the conventional connecting fitting has a connecting function of cross-connecting the horizontal pipes to the pipes of the columns at the side wall of the house, it does not have a dropless function of condensed water, so that the upper part of the house, especially the shoulder part, has no function. It had the drawback that it could not be used. Therefore, the inventors of the present invention conducted various trial researches on the development of the connecting fitting used for the upper part of the house having the dropless function, and as a result, developed a highly desirable dropless connecting tool having the above-mentioned functions that are practically satisfactory. .

The present invention has been made in view of the above circumstances, and it is possible to firmly and stably connect a shoulder lateral passage pipe on the upper part of a vinyl house to an arch pipe, and use the upper part of a greenhouse for plant cultivation.

Further, a U-shaped plate-shaped member having a U-shaped cross section and two leg plates slightly widened is combined with a wedge member that engages with both inner side surfaces of the U-shaped plate-shaped member. In a dropless connecting metal fitting for a plastic greenhouse using a connecting metal fitting and a seat restraint, the U-shaped plate-shaped member has a bent top formed on an inner surface of a bent surface that holds the vinyl house arch pipe, and both leg plates. Each of the portions is formed with a notch having a shape capable of receiving and holding the shoulder lateral threading pipe at a position separated from the bent top by a distance necessary for providing a drop pressing effect, while the wedge member forms the arch pipe. The U-shaped plate-shaped member has a curved part that presses and holds the bent inner surface and both plate-shaped leg parts. The same taper is formed to allow the wedges to be wedged, and the position of the notch formed in both leg plates of the U-shaped plate member gives a drop-press function to the arch pipe and the lateral shoulder pipe. It is a drop-press connecting metal fitting in a vinyl house characterized by being connected.

Furthermore, a U-shaped plate-shaped member having a U-shaped cross-section and two leg plates slightly widened, and a wedge member that engages with both inner side surfaces of the U-shaped plate-shaped member are combined. In a vinyl house using a connecting metal fitting and a seat restraint string, the U-shaped plate member is formed with a bent top part on the inner surface of a bent surface that holds the arch pipe of the vinyl house, and on both leg plate parts. A cutout having a shape capable of receiving and holding the shoulder transverse pipe is formed at a position separated by a distance required for providing a dropless effect from the bent top, while the wedge member forms the arch pipe by the U-shaped plate. Each of the plate-shaped members has a pad-shaped portion that presses and holds the bent-shaped inner surface of the plate-shaped member, and both plate-shaped leg portions. A dropless connecting metal fitting is used, which forms a taper of the U-shaped plate-like member and gives a dropless function to the shoulder portion inside the greenhouse by the positions of the notches formed in both leg plate portions of the above U-shaped plate member. It is a plastic greenhouse. The U-shaped plate member and the wedge member are both made of a rigid metal material having elasticity.

[Action]

 Next, the operation of the present invention will be described. Generally, in a greenhouse, first, a large number of arch pipes are sequentially arranged in parallel in the depth direction at predetermined intervals, and inside of them, a plurality of arch pipes orthogonal to these arch pipes are arranged. Horizontal straight pipes (horizontal pipes) are arranged in the depth direction, and at their intersections, wedge members that engage with both inner side surfaces of U-shaped plate-like members are connected to each other at the time of this driving. In this case, the arch pipe with the curved portion curved can be inserted securely while holding it in both the front and rear parts, so that it can be inserted securely, and the arch pipe is firmly pressed and held by the curved portion even after driving into the structural aggregate. After that, a vinyl sheet is stretched on the outside of this structural aggregate so as to cover it, but at that time, especially at the place where it hits the shoulder of the arch pipe, the shoulder horizontal pipe is fixed. Connecting bracket And remembering drop-less function in the leg plate section itself.

Condensed water generated on the inner surface of the vinyl sheet above the shoulder lateral passage pipe flows along the inner surface of the sheet and collects on the restraining string portion while flowing down, and is transferred to the shoulder lateral passage pipe which comes into contact. Since it drips from that part to the cultivated plant in the greenhouse and damages the cultivated plant, condensed water generated on the inner surface of the vinyl sheet above these shoulder lateral pipes should not be touched by the shoulder lateral pipes. Further, the leg plate portion of the U-shaped plate member, which is the connecting metal member, is formed to have a dropless effect in order to flow down to both sides of the house along the inner surface of the side wall of the house.

With this, it is possible to provide a dropless function between the arch pipe gripped by the bent surface of the U-shaped plate member and the shoulder lateral passage pipe held in the notch, and also the U-shaped plate. Since a drop-less function can be given to the shoulders inside the vinyl house by the shaped members, all the condensed water generated on the inside surface of the vinyl sheet travels down the inside surface of the house side wall and flows down to the ground on both sides of the house, Does not damage cultivated plants or cause root rot.
