DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe house as a greenhouse having a framework formed by a large number of arched pipes and the like, in which a transparent sheet made of synthetic resin spread on the framework can be fixed and water droplets condensed on the sheet. The present invention relates to a dew collection device capable of discharging water to the outside.

[0002]

2. Description of the Related Art Generally, a pipe house of this type has a large number of arched pipes erected on the ground, a sheet fixing device is erected between the pipes in a lateral direction, and is extended above the arched pipes. It is stated that a transparent sheet made of a synthetic resin is fixed via a sheet fixing device.

[0003] This sheet fixing device is widely known in the industry as "Vinipet (registered trademark)", which includes a dovetail frame having a narrow opening portion and an elastic locking member fitted into the dovetail frame. And fixing the sheet by pushing the sheet into the dovetail frame with an elastic locking line.
The sheet fixed by the sheet fixing device is considerably tensed because it is fixed at a plurality of places, but is installed between the fixing devices of the plurality of sheets to prevent flutter due to wind pressure or the like. It is usually held down with a synthetic resin band or string.

[0004] Further, usually, a ventilation device is provided on a shoulder portion or a side portion of the pipe house, and air in the house is ventilated to adjust temperature and humidity in the house. This ventilation system
This is performed by connecting a pipe to one end of the sheet and rotating the pipe below a band or the like to take up or rewind the sheet.

Further, in recent pipe houses, it is required to treat water droplets condensed on the inner surface of the sheet. This is because if water droplets attached to the sheet fall on the soil in the house, the root of the plant will rot, causing disease, poor growth, and poor greenhouse. It is necessary to drain outside. For this reason, recently, a dew collecting device has been attached to the sheet fixing device, and the dew condensation is integrally formed at one end of the dovetail groove frame as disclosed in Japanese Utility Model Publication No. 2-6770. A gutter frame having an L-shaped cross-section, a hollow joint attached to an arbitrary position of the dovetail frame, and a hose connected to an end of the joint, and a gutter for water droplets condensed on the inner surface of the sheet. It is led to the frame and then drained out of the house via a joint and a hose.

[0006]

The above-mentioned conventional sheet fixing apparatus has the following disadvantages.

There is no problem in fixing one sheet to the sheet fixing device. For example, a roof-side sheet that allows only sunlight to pass therethrough, and a sheet that transmits and winds the sunlight and takes up ventilation. In the case of simultaneous fixing, it is necessary to overlap the sheets to fix the ends of the sheets with a single fixing device. In this case, two elastic locking lines are required, and a narrow space is required. However, there are disadvantages that two fixing operations are required within the above, increasing the number of parts and making workability difficult. In particular, when the roof side sheet and the ventilation sheet are overlapped, the rainwater falls smoothly, and the ventilation sheet is fixed first so that the rainwater does not seep into the house and fall. The roof side sheet is fixed on the ventilation sheet. However, the ventilation sheet loses its durability due to repeated winding and rewinding work, and it needs to be replaced from time to time.In this case, the fixing of the roof side sheet must also be released. In addition, there is a problem that the work of replacing the ventilation sheet is troublesome, and sometimes the roof sheet is damaged.

When the band or the string is erected, the gap between the band and the arch pipe is formed at an interval corresponding to the seat height of the dovetail frame. For this reason, when sequentially winding or rewinding the sheet wound on the pipe, if the diameter of the sheet bundle wound on the pipe becomes larger than the above gap, the sheet bundle interferes with the band and is rubbed, and the sheet is damaged. In addition, uniform winding and rewinding of the sheet cannot be performed, and the sheet becomes uneven or the sheet bundle becomes oblique. Furthermore, the operation of winding and unwinding the sheet against the elasticity of the band or the like is heavy and the operation is difficult.

On the other hand, the above-mentioned conventional dew collecting device has the following disadvantages.

That is, since the L-shaped gutter frame connected to the end of the dovetail frame can be used only for collecting dewdrops, it has no versatility as a sheet fixing part and is bothersome. It is necessary to mold separately from a general dovetail frame, which increases the processing cost and increases the manufacturing cost of the greenhouse itself.

[0011] Therefore, an object of the present invention is to make it possible to extend only one sheet and to extend two sheets independently. It is an object of the present invention to provide a dew collection device which can smoothly wind up or rewind a ventilation sheet by enlarging the gap, and can be used not only for fixing the sheet but also for collecting and draining dew on the back surface of the sheet.

[0012]

In order to achieve the above-mentioned object, a means of the present invention combines a fixing device for two sheets longitudinally arranged at an arbitrary interval with a fixing device for each sheet. A first dovetail frame with a narrow opening, a second dovetail frame with a narrow opening connected diagonally below the first dovetail frame, The dovetail frame is formed of an elastic locking line fitted to one or both of the first and second dovetail frames, and the first and second dovetail frames are inclined obliquely from both ends of the horizontal bottom. And a pair of first and second sheet support pieces standing upright, and the second dovetail frame is located near the lower end of the first dovetail frame via one of the first sheet support pieces. Are joined together, the joints have a horizontal bottom and holdings at both ends of this bottom And two adjacent fixing devices are connected via a joint to form a groove formed by the horizontal bottom portion of the first dovetail frame and the first sheet supporting piece of the second dovetail frame. The apparatus is characterized in that it is used as a gutter and is opened in a gap between the fixing devices of the two sheets, and water droplets condensed on the inner surface of the sheet are discharged to the outside through the groove and the gap.

In this case, it is preferable that the upper end of one of the first support pieces forming the second dovetail frame is directly and integrally connected to the lower end of the first dovetail frame.

Similarly, one of the first sheet supporting pieces constituting the second dovetail frame is connected to the first sheet supporting piece via the connecting piece folded from the upper end of the second supporting piece constituting the first dovetail frame. Is preferably provided continuously with the lower end of the dovetail frame.

[0015]

With the first and second dovetail frames,
By using only the first dovetail frame, only one sheet can be extended, and two sheets can be independently extended using the first and second dovetail frames. When a sheet holding band or a string is passed over the first dovetail frame, the distance between the band and the like and the framed arch pipe is equivalent to the total height of each seat of the first and second dovetail frames. Therefore, the wound bundle of the ventilation sheet can smoothly rotate without interfering with the band or the like. Water droplets condensed on the sheet can be collected outside using the grooves formed by the first dovetail frame and the second dovetail frame as gutters.

[0016]
