Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the improvement of rain gutter members for greenhouses, and in particular, the rain gutter members can be easily connected, prevent rain leaks, and have side openings. Regarding rain gutter parts for vinyl greenhouses that are free of charge.

[Conventional technology]

Conventionally, regardless of whether a greenhouse is a single building or a multi-building type, it is necessary to guide rainwater, snowmelt water, etc. flowing down from the roof to the gable side and drain it to a predetermined location without causing it to drip.

In other words, in the case of a single building, rainwater flowing down from the roof,
If snowmelt water, etc. is allowed to flow straight down, the water will seep into the soil on both sides of the greenhouse, creating an excess of moisture, which can cause root rot and disease in severe cases, so install side gutters. It is necessary to guide rainwater, snowmelt water, etc. to the gable and drain it to a designated location.

In addition, in the case of multi-buildings, if rainwater, snowmelt water, etc. is allowed to flow down from the roof, a large amount of water accumulates in the valleys and does not flow smoothly to the gable side, causing the vinyl sheet to sag and, in severe cases, If the sheet is torn, a large amount of water will flow into the house, so it is necessary to install valley gutters to guide rainwater and snowmelt water to the gable and drain it to a designated location. Of course, it is necessary to install side gutters not only in the valley but also on the outside for the same reason as in the case of a single building.

Furthermore, the side gutters and valley gutters must be attached to the frame before the vinyl sheet is stretched, and the vinyl sheet covering the roof surface must be fixed at the side gutters and valley gutters.

Conventionally, the method of clamping the ends of a vinyl sheet between strips and fixing them by nailing is extremely troublesome and requires a lot of labor and time. Also,
When the vinyl sheet is agitated by strong winds, it begins to tear at the nail holes at the ends, and often completely tears after being used for a year. Furthermore, with the above-mentioned fixing method, it is very troublesome to remove the vinyl sheet, making it difficult to replace the vinyl sheet for partial repair.

Furthermore, due to dew condensation in greenhouses, large amounts of water droplets adhere to the inner surface of the vinyl sheet that covers the roof, and this drops onto the sheet and into the greenhouse, causing root rot in some crops. In addition, high humidity can cause diseases in crops, and fruit vegetables such as tomatoes may split.

For this reason, conventionally, vinyl sheets that have been subjected to drip-proof treatment, drip-proof treatment, or drip-proof treatment have been used,
A double gutter system is used, with a gutter installed underneath the external side gutter and valley gutter.

In addition, as shown in FIGS. 3 to 7, both sides of a rain gutter member 1 made of a strip-shaped thin steel plate are bent upward, and the side sides 2 and 2, a strip groove 3 having a dovetail cross section is provided on the side edges 2, 2, and both side portions 5, 5 connected to the opening edges of the strip groove 3 are inclined to form a gap 6, A large number of depressions 8 are provided in both side portions 5, 5 by press molding.

Then, this rain gutter member 1 is placed and fixed on a vertical beam installed on a support, and the ends of the vinyl sheet that covers the roof surface are arranged on the sides of the rain gutter member 1, and the corrugated locking wire is attached. The wire is pushed into the strip groove 3 and fixed to the left and right inner walls of each strip groove 3 by the elastic force of the wire itself.

In addition, the method disclosed in Japanese Utility Model Application Publication No. 54-145642 forms a band-shaped groove on one side or both left and right sides of a band-shaped thin steel plate, bends both left and right sides upward at an appropriate angle, and The part is bent outward over its entire length to form a water droplet receiving groove with an appropriate cross-sectional shape.

[Problem that the invention attempts to solve]

However, in conventional greenhouses, the drip-proof treatment applied to the vinyl sheet disappears within a short period of time, and a large amount of water droplets will adhere to it. It is smooth and concentrated at the bottom of side gutters and valley gutters, and flows through the framework of vertical beams, side columns, intermediate supports, etc., and permeates to the ground.
There were drawbacks such as the surrounding crops being overgrown due to excess moisture, and the frames such as the vertical beams and intermediate supports corroding early, resulting in a shortened lifespan.

In addition, double gutters have the advantage of being able to receive and eliminate all water droplets other than those that fall on the way.
Houses that can be installed are limited to pipe houses, etc., which lacks versatility, and not only is assembly and repair troublesome, but the supporting members are weak, making the upper side gutter and valley gutter easy to damage and deform, and the upper gutter is prone to damage and deformation. The lower side gutter or valley gutter quickly corrodes due to the difference in the amount of water flowing between the side gutter or valley gutter and the droplets of rainwater/melted snow water. In other words,
There was a problem in that water droplets accumulated in the lower side gutters and valley gutters and stagnated, resulting in significant corrosion.

Furthermore, in the method disclosed in the above-mentioned Japanese Utility Model Publication No. 59-42, the ends of the vinyl sheet covering the roof surface are clamped and fixed in the strip grooves 3 using corrugated locking wires. However, water droplets that adhere to the inner surface of the vinyl sheet covering the roof surface due to dew condensation flow down the upper part of the rain gutter member, but when the vinyl sheet is not pressed against the side surface of the gutter, the wavy locking line depression on the edge of the opening between the peaks of the mountain 8
This has the drawback that it does not easily enter the strip groove 3, and most of it drips into the greenhouse, causing root rot in some parts of the crop.

In addition, the rain gutter member 1 cannot be connected due to the strip grooves 3 and the depressions 8, and in order to connect it, the end of the rain gutter member 1 must be cut out, and rainwater leaks into the house from here. The disadvantage was that it had a negative impact on the crops in the greenhouse.

Furthermore, in the vinyl sheet disclosed in Utility Model Application No. 54-145642, since both sides near the center are flat, the edges of the vinyl sheet do not come into close contact with the sides and are exposed to wind. Moreover, the structure of this rain gutter member requires notches at both ends for connection, which has the disadvantage that rainwater leaks into the greenhouse and adversely affects crops.

In view of the above circumstances, the inventor has conducted various research and found that
The present invention has been completed, and the connection between rain gutter members is easy, water leakage can be reliably prevented, the vinyl sheet will not be damaged by tearing, and the inner surface of the vinyl sheet that covers the roof surface due to dew condensation. To provide a rain gutter member for a vinyl house capable of guiding and draining all of the water droplets attached to the greenhouse, except those that fall on the way, to the outside of the house.

[Means for solving problems]

In order to achieve the above object, the present invention provides strip grooves on both sides of the central bottom made of a strip-shaped thin steel plate, bends the both sides upwards, and expands both gutter members of a vinyl house outward. The both sides are formed into upwardly curved curved surfaces, and the sides of the both sides are flat surfaces inclined in the opposite direction to the curved surfaces via strip grooves, and the edges of the flat surfaces are free of dew condensation. A water receiving groove is formed, and the strip groove is narrow at one end and wide at the other at both ends of the rain gutter member, so that it can be fitted during connection.

[Effect]

Next, to explain the operation of the present invention, a strip groove with a narrow opening width is formed on the side of the rain gutter member, and this strip groove is narrow at one end and narrow at the other end of the rain gutter member. Since it is wide and can be fitted, it is easy to connect and fix to the gutter part of a greenhouse, and there is no risk of water leaking from the connecting part.

In addition, since condensation water receiving grooves are formed on the edges of both sides of the rain gutter member, water generated by dew condensation inside the vinyl greenhouse flows into these receiving grooves while flowing along the inner surface of the vinyl sheet. Water is drained outside the house without falling into the house.

〔Example〕

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

In the drawings, the same or equivalent parts as in the conventional example will be described with the same reference numerals.

This embodiment is shown in FIGS. 1 and 2, in which both sides of a central portion 11 of a rain gutter member 1 made of a strip-shaped thin steel plate are bent upward. Both sides of the central portion 11 are expanded outwardly to form side edges 12 forming gently curved surfaces. Near the upper end of the side 12, a strip groove 13 with a narrow opening parallel to the longitudinal direction of the rain gutter member 1 is formed.

Furthermore, a condensation water receiving groove 1 is provided at the edge of the side 12.
5 is provided, and this receiving groove 15 is for guiding water condensed on the inner surface of the vinyl sheet to the gable side of the house and draining it to a predetermined position, as shown in a, b, and c in Fig. 2. The cross section is circular or oval.

Next, this example was placed on a vertical beam installed on the support of a greenhouse, and after fixing it with fixing fittings, the end of the vinyl sheet covering the roof of the greenhouse was placed on the side of the rain gutter member 1. A corrugated locking wire is pushed into the strip groove 13 provided on the side 12, and the bottom 14 of the strip groove 13 is pushed by the elastic force of the corrugated wire itself.
Secure it to the nearby inner wall.

At this time, since the side edges 12 of the rain gutter member 1 are curved, the edge of the vinyl sheet adheres to the side edges 12, so it will not tear even if it is blown by the wind, and water will not leak into the house. do not have.

In addition, water droplets that adhere to the inner surface of the vinyl sheet covering the roof surface due to condensation inside the greenhouse can be easily drained by the flat sides on both sides, and most of them are deposited on the upper edges of both sides 12 of the rain gutter member 1. The water is drained outside the greenhouse through the provided condensation water receiving groove 15 and does not adversely affect the crops.

Furthermore, since the strip grooves 13 at both ends of the rain gutter member 1 of this embodiment can be fitted, and the side edges 12 are curved, it can be fitted easily when installed in a house.
Since they are easy to connect and do not shift, water leakage from the connecting parts can be completely prevented.

Further, both sides 12, 12 of the rain gutter member 1 can be easily expanded, and the opening angle can be easily set to suit the greenhouse at the work site.

[Effect of idea]

Since the present invention has the above configuration,
When installing on the vertical beams of a greenhouse, it is extremely easy to fit and connect rain gutter members, and since the connection is made at both ends of the strip grooves on both sides, the connection is strong and can be used for many years. The structure does not come loose, and water leakage from the joints can be completely prevented, greatly extending the life of the greenhouse frame and preventing harmful effects such as root rot on crops.

In addition, since the sides are gently curved, the ends of the vinyl sheet adhere well and rainwater is completely drained.

Furthermore, since condensation water receiving grooves are provided on the sides of the rain gutter members, water droplets generated due to dew condensation inside the greenhouse flow down the inner surface of the vinyl sheet, and the flat sides allow water to drain away. Most of the water goes into this receiving groove and can completely drain water outside the greenhouse, which is highly effective in eliminating the risk of crop root rot.

In addition, the sides are gently curved and generally have a smooth slope, so the water drainage is large and does not rust due to dust.
