Description

[Detailed Description of the Invention] The present invention relates to a drip-proof structure for the roof of a greenhouse for agriculture and horticulture.

The roof of conventional general agricultural and horticultural greenhouses is
As shown in the figure, a plurality of purlin materials 1 having an approximately C-shaped cross section with open sides are arranged on beams 2 at intervals with the side openings facing the ridge. It is formed by attaching a roofing material 3, such as a corrugated sheet made of synthetic resin, on top of the panels 1 and 1.

However, in the case of a roof having such a structure, when the water vapor inside the house is cooled and condensed on the lower surface of the roofing material 3 due to the temperature difference between the inside and outside of the house, the condensed water droplets 4 are deposited on the roofing material 3 as shown in FIG. Tanibe 3
1, transfers to the purlin material 1, and then the purlin material 1.
Since the water drops travel down the back side of the plant and fall from the lower end, there are problems in that these falling water droplets can adhere to cultivated plants, causing disease in the plants, or cause discomfort to workers.

The present invention was developed in view of the above problems.The existing purlin material is used as a gutter for collecting and draining condensed water droplets, and a specific drip-proof member is fixed to this purlin material to prevent condensed water droplets from forming on the underside of the roof material. The present invention aims to provide a novel drip-proof structure that can sufficiently prevent condensed water droplets from falling from the roof by efficiently guiding them into the interior of the purlin material.

The present invention will be described in detail below with reference to examples. That is, the drip-proof structure for the roof of an agricultural and horticultural greenhouse according to the present invention is a structure in which purlin materials 1... with a roughly C-shaped cross section and open sides are arranged at an angle so that the side openings face the ridge as shown in Fig. 1, and roofing materials 3 are attached to the purlin materials 1..., and a belt-shaped drip-proof member 5 equipped with hair-like bodies 51... for guiding water droplets is fixed to the outer surface of the hanging pieces 12 at the upper edges of the side openings 11 of the purlin materials 1 as shown in Fig. 3.

As shown in FIG. 4, this drip-proof member 5 has a large number of hair-like bodies 51 for guiding water droplets that are relatively strong and stand up, with mutual spacing such that condensed water droplets do not pass through without contact. This hair-like body 51 is provided on the upper edge of the band-shaped base material 52 with an opening, as shown in FIG.
... is bent over the entire length of the hanging piece 12 of the purlin material 1 so that its tip is in contact with the lower surface of the roofing material 3 in a state where it is curved to the side opposite to the purlin material 1 (ridge side). In this case, if the roofing material 3 is a flat plate made of synthetic resin, it is necessary to contact the hair-like bodies 51 over the entire width of the roofing material 3, but if the roofing material 3 is a corrugated sheet as shown in FIG. If so, it is sufficient to simply bring the hair-like bodies 51 into contact with the lower surface of the valley portion 31 through which the condensed water droplets 4 flow.

A desirable specific example of such a drip-proof member 5 is as shown in FIG. and apply the adhesive 5
3, to which the base of a hair-like body 51 made of short threads of soft or semi-hard synthetic resin, glass fiber, synthetic fiber, natural fiber, etc., like a brush, is attached with adhesive force to the upper part of As shown in FIG.
An example is one in which an adhesive 53 is applied to one side of the band-shaped base material 52. Since these are coated with adhesive 53, they can be easily fixed without using any fasteners by simply pasting them on the outer surface of the hanging piece 12 of the main building material 1, and the band-shaped base material 52 has flexibility. This is because it has the advantage that it can be stored in a rolled state like ordinary adhesive tapes.

In addition, if the raw material resin of the hair-like body 51 or the strip-shaped base material 52 is highly water-repellent, the wetting characteristics can be improved by applying hydrophilic treatment to the surface, and the dew condensation water droplets 4 on the lower surface of the roofing material 3 can be improved. It is desirable that the liquid can be easily transferred to the drip-proof member 5.

In the drip-proof structure of the present invention as described above, the third
As shown in the figure, when the condensed water droplets 4 flowing along the lower surface of the roofing material 3 come into contact with the hair-like bodies 51 of the drip-proof member 5, they transfer to the hair-like bodies 51, and then flow along the surface of the strip-like base material 52 to the main building. The material 1 falls from the lower end of the hanging piece 12.
This fallen condensed water droplet 4 is absorbed by the side opening 11 of the main building 1 because the main building 1 has a substantially C-shaped cross section with a side opening 11 and is tilted so that the side opening 11 faces the ridge. It enters the interior and accumulates at the bottom, then flows inside the main building material 1 and is drained from the end along the side wall of the house.

Particularly, in the present invention, the drip-proof member is attached to the hanging piece 1 of the purlin material 1.
2, the drip-proof member 5 can be fixed to the hanging piece 12 without modifying the roof by using the existing main building material 1 as a gutter, making it extremely inexpensive and easy to install the drip-proof member 5. It is possible to configure the structure. When using the drip-proof member 5 as shown in FIGS. 5A and 5B, the construction is very easy because the drip-proof member 5 only needs to be attached. Nevertheless, since the elastic hair-like body 51 is curved toward the ridge and its tip is in contact with the lower surface of the roofing material 3, the condensed water droplets 4 flowing along the lower surface of the roofing material 3 are transferred to the hanging piece 1.
Before it hits the upper end of the hanging piece 12, it is captured by the elastic hair-like body 51 and quickly guided to the lower end of the hanging piece 12. Therefore, not only is it possible to prevent the condensed water droplets 4 from hitting the upper end of the hanging piece 12 and spreading laterally and reaching the back surface of the main roof material 1, but also to prevent the roof material 3 from floating due to strong winds, etc. There is an advantage in that even if the contact goes up, the contact state can be maintained at all times.

The present invention efficiently guides and collects the condensed water droplets 4 on the lower surface of the roofing material 3 into the interior of the purlin material 1 by means of the drip-proof member 5 fixed to the purlin material 1 as described above, and the water is collected from the end of the purlin material 1 into the house. By discharging water along the side walls, it prevents condensed water droplets from falling from the roof, so there is no risk of falling water droplets adhering to cultivated plants and causing diseases, or causing water droplets to boil over workers. It is possible to sufficiently eliminate the drawbacks that cause discomfort.
