Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention includes an upper edge of a ventilation vinyl sheet that is rolled up and stretched over the side wall of an agricultural greenhouse for ventilation; This invention relates to a vinyl sheet tensioning tool for agricultural greenhouses, which can be used to secure the lower edge of a ceiling-side vinyl sheet stretched above the vinyl sheet.

(Prior art and its problems) As mentioned above, in agricultural greenhouses,
When fixing the upper edge of a ventilation vinyl sheet that can be rolled up for ventilation on a side wall and the lower edge of a ceiling-side vinyl sheet that is stretched above this, the ventilation vinyl sheet a rod-shaped member for fixing the vinyl sheet for fixing the upper edge of the
A vinyl sheet fixing rod member for fixing the lower edge of the vinyl sheet on the ceiling side must be installed horizontally in parallel to the pillars of the greenhouse. Conventionally, the upper and lower vinyl sheet fixing rod members were each attached to the support separately through attachment means, resulting in a relatively large gap between the upper and lower vinyl sheet fixing rod members. This gap caused negative effects such as reducing the heat retention effect of the greenhouse.

(Means for Solving the Problems) The present invention provides a vinyl sheet stretching tool that can solve the conventional problems as described above. It consists of a fixing means for fixing the fixing rod-like members in parallel to the greenhouse pillars, and a band-like plate that covers the gap between the two vinyl sheet fixing rod-like members fixed by the fixing means,
This band-shaped plate is fixed to the support column integrally with the two vinyl sheet fixing rod-shaped members.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In Figures 1 and 2, reference numeral 1 indicates an arch-shaped support on the side wall of the greenhouse, and a main body is placed outside near the upper end of the vertical part of this arch-shaped support 1 (approximately 1.8 m above the ground). Vinyl sheet 3 on the ceiling side via the invented vinyl sheet tensioning tool 2
The lower edge and the upper edge of the rollable ventilation vinyl sheet 4 are fixed.

As shown in FIGS. 3 to 5, the vinyl sheet tensioning tool 2 is attached to a vinyl sheet 3 on the ceiling side.
To attach a vinyl sheet fixing rod member 5 for fixing the lower edge and a vinyl sheet fixing rod member 6 for fixing the upper edge of the rollable ventilation vinyl sheet 4 to the arch-shaped support 1 in parallel. and a belt-like plate 8 which covers the gap between the upper and lower rod-shaped members 5 and 6 and also serves as a part of the fixing means 7.

The fixing means 7 includes a main body 9 and a fixing wedge 1.
0, the strip plate 8 and the auxiliary pipe support member 11
It consists of The main body 9 has a U-shaped side surface, and has upper and lower side plate portions 12 having recesses 13 into which the support columns 1 are fitted, and recesses 1.
Folded locking portions 14 are formed at both free ends of 3. The auxiliary pipe support member 11 is
A pair of left and right support plates 16 each having an auxiliary pipe material through hole 15, and a connecting plate portion 1 that connects both support plates 16.
7, and in this connecting plate part 17, the strip plate 8 is fixed at the center position in the width direction at appropriate intervals in the length direction, and locking parts 18 are provided at the bases of both side edges of both support plates 16. It is formed.

To explain how to use it, the strip plate 8 is placed on the outer side of the support 1 at an appropriate height with the side where the auxiliary pipe support member 11 is removed, and the strip plate 8 is placed on the top and bottom of the auxiliary pipe support member 11. One side edge of the rod-shaped members 5 and 6 for fixing the vinyl sheet is fitted into the locking portion 18. In this state, the main body 9 is applied from inside the support 1 so that the support 1 fits into the recessed part 13, and the upper and lower sides of the strip plate 8 and the adjacent vinyl sheet fixing rod members 5 and 6 are Folding locking part 1 above and below against the side edge
4 is pressed so as to pass forward with elastic deformation of the upper and lower side plate portions 12. As a result, as shown in the figure, the outer edges of the two vertically parallel vinyl sheet fixing rod members 5 and 6 are connected to the strip plate 8 and the main body 9.
It is in a state where it is sandwiched between the folded back locking part 14.

Next, the fixing wedge 10 is press-fitted along the strip plate 8 between the rear vertical wall 19 of the body 9 and the column 1 as shown, and the body 9 is drawn inwardly with respect to the column 1. Therefore, the folding locking part 14 clamps and fixes both upper and lower edges of the strip plate 8 with the support 1 via the outer edges of the rod-shaped members 5 and 6 for fixing the vinyl sheet. Moreover, the two vertically parallel vinyl sheet fixing rod members 5 and 6 have their mutually adjacent inner edges connected to the locking portion 18 of the auxiliary pipe support member 11.
At the same time, the outer edge is locked by the folded locking part 14 of the main body 9, and is fixed along both upper and lower edges of the strip plate 8.

In addition, in the drawing, the spacing between the auxiliary pipe support members 11 on the strip plate 8 and the spacing between the struts 1 are made equal, and the auxiliary pipe support members 11 are installed so as to be located at the position of each strut 1. The position of the auxiliary pipe support member 11 may be shifted with respect to the above. Since the strip plates 8 have a predetermined length, the strip plates 8 must be connected in the length direction during use. This connection of the strip plates 8 is performed at the position of the support 1, and the abutting portions of the two strip plates 8 can be fixed simultaneously using one main body 9 and the fixing wedge 10.

The two vinyl sheet fixing rod members 5 and 6 attached to the pillar 1 as described above are conventionally well-known, and the ends of the vinyl sheets 3 and 4 fitted into the rod members 5 and 6 are A clip 2 whose edges are fitted into the rod-like members 5 and 6 against elasticity.
It can be fixed by 0. Further, the auxiliary pipe 21 can be inserted into each through hole 15 of the auxiliary pipe support member 11 along the strip plate 8. This auxiliary pipe 21 can be used for tying a sheet holding rope for holding down the vinyl sheets 3 and 4 from the outside between the supports 1, or for tying a rope for holding the rolled up sheets 4 together. Furthermore,
It is also possible to connect vertical pipes for other purposes to the auxiliary pipe 21.

In the above embodiment, the strip plate 8 for covering the gap between the rod-shaped members 5 and 6 is a part of the fixing means 7 (i.e., the auxiliary pipe support member 1 with the locking part 18
However, in this structure, the auxiliary pipe support member 1 is used as the long strip plate 8.
It is necessary to use a plate material having a thickness that allows the parts 1 to be fixed by welding or the like, which not only increases the weight but also increases the cost. Therefore, if this is a problem,
Instead of fixing the auxiliary pipe support member 11 with the locking part 18 to the strip plate 8 as shown in FIGS. 6 and 7, the auxiliary pipe support member 11 is attached to another substrate 22 (as shown in Although it is desirable that the pair of left and right support plates 16 be used also as the connecting plate section 17, a substrate 22 may be used separately from the connecting plate section 17), and the four corners of the substrate 22 are connected to the main body 9. It can be used to correspond to the folding locking part 14 of. In this case, as the strip plate 8, a thin and inexpensive plate material such as a galvanized iron plate can be used as shown in the figure.

(Operations and Effects of the Invention) As described above, when using the vinyl sheet tensioning tool for agricultural greenhouses of the present invention, the vinyl sheet fixing rod-like member for fixing the upper edge of the ventilation vinyl sheet is used. , the vinyl sheet fixing rod member for fixing the lower edge of the ceiling side vinyl sheet can be installed on the support of the greenhouse at the same time with one fixing means, and the strip plate that is attached at the same time, Since the gap created between the upper and lower vinyl sheet fixing rod members is closed, problems such as a decrease in the heat retention effect of the vinyl greenhouse are also solved. Further, the band-shaped plate cooperates with two parallel vinyl sheet fixing rod members to increase the strength of the vinyl greenhouse.
