Description

[Detailed description of the invention] The present invention relates to a pipe attachment device, and more specifically, a pipe suitable for connecting a string, etc. for holding a vinyl membrane of a greenhouse to a pipe, and fixing this pipe to a valley gutter. relating to the mounting device.

In general, a greenhouse for growing plants, etc. has many pipes bent in an inverted U shape, and a transparent vinyl sheet is stretched around the outer circumference of the pipe to absorb solar energy into the greenhouse through the vinyl sheet.It is a so-called tunnel type greenhouse. is known for its vinyl greenhouses.

In the above vinyl greenhouse, it is difficult to install the stretched vinyl sheet under tension.
Looseness or uneven wrinkles inevitably occur in the vinyl sheet, and especially if the distance between pipes is large, the sheet stretched between them will sag, and if external forces such as strong wind and rain are applied, it will sag outward or inward. A bulging phenomenon occurs, causing the sheet to flap around and cause vibrations, which not only causes the sheet to break, but also makes the greenhouse itself unstable.
There is a risk of destroying the structure.

For this reason, conventionally, a valley gutter was placed between the pipe houses, and one end of the vinyl sheet was dropped into this valley gutter to allow rainwater on the vinyl sheet to flow outside through the valley gutter, but this valley gutter A pipe is fixed to the pipe, and while one end of a string is fixed to this pipe, the tension of the string is used to prevent the vinyl sheet from sagging or becoming uneven.

However, even in such a method, it is troublesome to install the string fixing pipe along the valley gutter, and the mounting structure is also complicated.

In addition, when the temperature inside the pipe house becomes high, one end of the vinyl sheet may be rolled up to form a ventilation window each time, but if the vinyl sheet is held down by the tension of the string mentioned above, this The work of winding and unwinding the vinyl sheet is troublesome and work efficiency is significantly reduced.

Therefore, an object of the present invention is to provide a pipe attachment device suitable for easily fixing a pipe for tying a string for holding a vinyl sheet to a gutter of a greenhouse, and also facilitating the work of winding the vinyl sheet. It is to be.

To achieve this objective, the present invention consists of a pipe insertion member and a wedge, and when the pipe is inserted into the pipe insertion part of the pipe insertion member and the wedge is inserted into the wedge insertion groove of the pipe insertion member, the pipe insertion member comes out. It is characterized in that it expands in the direction and is fitted and held in a groove such as a valley gutter.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Figures 1 and 2, the pipe house 1
A large number of pipes 2 bent into an inverted U-shape stand upright, and a transparent vinyl sheet 3 is spread over the pipes 2 via a sheet fixing device as a roof or wall surface.

Further, a valley is formed between the pipe houses 1 and 1 where the pipes 2 cross, and a valley gutter 4 serving as a rain gutter is provided in this valley, and this valley gutter 4 is detachably held on the pipe 2 via a fitting 5. ing. The lower end of the vinyl sheet 3 held on the pipe 2 is hung down over the valley gutter 4, so that rainwater on the vinyl sheet 3 flows out into the valley gutter 4.

A locking groove 6 having a groove shape with a cross section is formed in the upper part of both sides of the valley gutter 4 along the longitudinal direction.
A pipe insertion member 7 according to the present invention is fixed therein via a wedge 8.

A pipe 10 is inserted into the pipe insertion portion 9 of the pipe insertion member 7 along the longitudinal direction.
The end of the string 11 is connected to an arbitrary position of 0, and the tension of this string 11 pushes the outer surface of the vinyl sheet 3 downward, so that the vinyl sheet 3
This prevents swelling and unevenness.

The pipe insertion member 7 is formed by integrally molding a pair of opposing left and right wedge insertion grooves and a pipe insertion portion that stands upward from the wedge insertion grooves, and inserts the wedge insertion grooves into the locking groove 6. Insert wedge 8 into this wedge insertion groove.
When the wedge insertion groove is inserted, the wedge insertion groove expands outward and fits into the locking groove 6, so that it cannot be removed. In this state, the pipe insertion member 7 stands above both upper surfaces of the valley gutter 4, so a gap is formed between the pipe 10 and the valley gutter 4, and thereby, between the lower part of the string 11 and the upper surface of the vinyl sheet 3. A gap is also formed, and the string 11 does not touch the upper surface of the vinyl sheet 3 within this gap. Therefore, when the vinyl sheet 3 is rolled up and unwound to form the ventilation window 12 in the range of this gap, the tension of the string 11 does not act on the vinyl sheet 3, and the work is carried out smoothly.

Furthermore, the bundle 3a wrapped with vinyl sheet 3 is string 1
Since it is pressed downward by the tension of 1, it does not fall downward, and as a result, the ventilation window 12 remains open.

FIG. 3 is a perspective view of a pipe attachment device according to an embodiment of the present invention.

This attachment device A consists of a pipe insertion member 7 and a wedge 8.
The pipe insertion member 7 consists of a pipe insertion portion 9 having a C-shaped cross section and wedge insertion grooves 1 provided symmetrically on both sides.
3 and 13 and bilaterally symmetrical mounting parts 14 and 14 projecting outward, these pipe insertion part 9, wedge insertion grooves 13 and 13, and mounting parts 14 and 14 are integrally molded, and Insert the pipe 10 and insert the wedges 8 into the wedge insertion grooves 13, 13 with the mounting parts 14, 14 fitted in the locking grooves 6 of the valley gutter 4.
When inserted, the widths of the wedge insertion grooves 13, 13 and the attachment portions 14, 14 expand to the left and right by the width of the wedge 8, and the attachment portions 14, 14 are firmly fitted inside the locking groove 6 and cannot be removed. Therefore, the pipe insertion part 9 stands up on the valley gutter 4 with the pipe 10 inserted therein.

In the above embodiment, the wedge insertion grooves 13, 13 are omitted, and the attachment parts 14, 14 are provided with grooves along the longitudinal direction, and by inserting the wedge 8 into this groove, the wedge insertion groove 13 and the attachment part 14 can be used. It is possible to do so.

It is also possible to provide one or more ribs 15 on the outer periphery of the pipe insertion portion 9 for reinforcement.

FIG. 4 shows another embodiment of the present invention, in which a pipe holding portion is provided protruding from the wedge to prevent the pipe from falling.

That is, the attachment device B includes a pipe insertion portion 16 having a U-shaped cross section, a pair of right and left wedge insertion grooves 17, 17 integrally provided at the lower part of the pipe insertion portion 16, and a wedge inserted into the wedge insertion grooves 17, 17. It consists of 19.

The wedge 19 is a guide 2 inserted into the wedge insertion groove 17.
