Description

[Detailed Description of the Invention] Industrial field of use The present invention uses a part of the trough to promptly receive the condensed water generated on the inner surface of the sheet of the multi-storey greenhouse and flowing down to the trough. The present invention relates to a drainage structure for dew condensation water, which is carried out in order to prevent the harmful effects of drip or accumulation of dew condensation by flowing it into the trough.

Conventional technology In a multi-storey vinyl house, the roofs of each building are connected in series through a trough (Japanese Utility Model Publication No. 56-50753, Japanese Utility Model Publication No. 62-202150). In a greenhouse, since the room temperature is high and the amount of water sprayed on the crops is large, a large amount of dew condensation is generated on the entire inner surface of the sheet, and the dew grows gradually into large water droplets and propagates along the inner surface of the sheet to form valleys. It descends to the gutter. Therefore, a large amount of dew condensation water drops intensively at the trough, but in the past, no active measures for wastewater treatment have been provided for such concentrated dew condensation water drop. So that's the situation.

Problems to be Solved by the Present Invention As described above, the dew condensation water that is generated on the inner surface of the sheet and drops down to the trough trough intensively along the sheet, if left as it is, the trough trough Condensation water drips from the place, and the workers in the room are forced to wear rain kappa, and the crops at the location where the condensation water is dripping tend to cause root rot and disease, so the condensation water A measure to prevent dripping has become an issue to be solved immediately.

Means for Solving the Problems As means for solving the problems of the above-mentioned conventional techniques, the drainage structure of the dew condensation water in the valley gutter of the multi-storey vinyl house according to the present invention is as shown in the preferred embodiment in the drawings. At the upper end of the side wall of the valley gutter 1 and at the rear side of the seat tension position, a dew condensation water receiving part 4 for receiving the flow down of the dew condensation water 3 condensed on the inner surface of the sheet 2 is formed. A drip hole 5 is provided at the deepest part of the dew condensation water receiving part 4 in the trough 1, and a groove type gutter piece 6 for receiving the dew condensation water 3 is attached to the lower side of the water drop hole 5, and the gutter piece 6 is attached. The lower part of is connected to the valley of Tani 1.

In the drainage structure of the dew condensation water in the trough of the multi-storey type greenhouse, the water drop hole 5 is formed as the notch 5 at the joint end of the trough 1, and the trough piece 6 has the hooking piece 6a at the upper end thereof. It is elastically locked to the water receiving wall 7 standing outside the dew condensation water receiving portion 4. Further, the lower part of the gutter piece 6 is located below the seat tension position of the trough 1 and is inserted into a communication port 8'formed as a notch 8 at the end of the seam so that the trough 1 can be connected to the valley. Also features.

Action Condensation water 3 generated on the inner surface of the sheet 2 of the vinyl house and traveling down the sheet 2 reaches the condensation water receiving portion 4 of the trough 1 and is transferred to the condensation water receiving portion 4. In this way, the dew condensation water 3 whose water amount is gradually increased on the dew condensation water receiver 4 is
It flows upwards in the longitudinal direction of the trough 1, reaches the water drop hole 5, and flows down from there. The condensed water 3 that has flowed down the water drop hole 5 reaches the waiting trough piece 6 at a position directly below it, and is guided by the trough piece 6 to flow down into the valley of the trough 1.

Embodiment Next, an embodiment of the present invention shown in the drawings will be described.

FIG. 1 specifically shows the structure of the trough part in the multi-storey vinyl house. An inwardly bent curved surface portion 1b is formed on the upper portions of both side walls 1a, 1a of the trough 1 having a groove shape in which the groove width is expanded upwardly into an inverted trapezoidal shape, and then an opening is formed on the upper portion. A sheet fixing groove 1c having a narrow cross section and a groove shape is formed, and this is the sheet tension position. Further, on the upper side thereof, there is formed a dew condensation water receiving portion 4 which is bent outward in a direction substantially parallel to the bent surface portion 1b and has a flowing water gradient which goes outward with respect to a horizontal line. At the tip of the dew condensation water receiving portion 4, a water receiving wall 7 is erected at a height such that the received dew condensation water 3 does not overflow.

As shown in FIGS. 2 and 3, the troughs 1 are butt-connected to each other on the joint / receiver 28 arranged at the trough connection position. The support 28 and the valley gutter 1 are bolts 9
They are firmly bonded together (Fig. 4). The support 28 is the support 1
0 to the upper end with bolts 11 and 11 (second
(Fig.) Therefore, the trough 1 is supported by an elevated structure at a fixed height above the ground. In addition, the left and right arm portions 28a, 28 of the receiving tool 28
The beam member 12 is connected to a by bolts 13, and the skeleton between the adjacent troughs has a structure with high structural stability.

A pipe hole 22 is provided in the dew condensation water receiving portion 4 of the trough 1 and the curved surface portion 1b located directly below the dew condensation water receiving portion 4, and an end portion of an arch pipe 14 forming a roof frame of each building of the vinyl greenhouse is inserted and held therein. ing. The end portion of the arch pipe 14 is brought into contact with and supported by the pipe receiver 15b of the joint 15 which is attached by hooking the hook 15a on the curved surface portion 1b of the trough 1, and the wedge 16 is driven into the joint 15. The arch pipe 14 is fixed so as not to come off.

The sheet 2 as the roof covering material of each building is stretched outside the arch pipes 14 ... Installed as described above. However,
The root of the sheet 2 is not caught in the sheet fixing groove 1c but is simply wound into the take-up pipe 17. This is because it is necessary to ventilate the hot air remaining inside the roof to lower the room temperature, that is, to wind up the root of the sheet 2 in the trough portion to form an opening or to close the opening. Ventilation ventilation is performed by rotating the winding pipe 17 by hand or a rotating device (for example, refer to the rotating device described in Japanese Utility Model Laid-Open No. 62-202150) in forward and reverse directions.

As described above, in order to make it easy to rotate the take-up pipe 17 to open and close the valley bottom of the seat 2, the presser string 18 that presses the seat 2 against the arch pipe 14 is
As shown in the figure, connect the above-mentioned joint 1 to the side wall part on the opposite side of the trough 1.
A large gap 25 is formed at the bottom of the seat 2 for binding the fixed pipe 19 supported by the winding No. 5 to the winding pipe 17 up and down.

By the way, the condensed water 3 generated on the inner surface of the sheet 2 stretched as described above and traveling down the sheet 2 is substantially contacted by the valley hem of the sheet 2 in the trough 1 as shown in FIG. At the position immediately above the sheet fixing groove 1c, which is the sheet tension position, the water drops are transferred to the dew condensation water receiving portion 4 due to the surface tension of the water droplets, and are accumulated at the bottom of the dew condensation water receiving portion 4. The drainage structure for promptly and positively removing the condensed water 3 is configured as follows.

That is, as shown in FIG. 3, a notch 5a of an appropriate size is provided for the fall of the condensed water from the deepest part of the condensed water receiver 4 to the water receiving wall 7 at the seam end of the trough 1 and adjacent to each other. A single water drop hole 5 is formed by combining the two notches 5a, 5a of the sluice trough 1, 1 (FIG. 4). Below the water drop hole 5, a trough piece 6 having a groove width slightly wider than the mouth width of the water drop hole 5 is attached (FIGS. 4 and 5). In the upper portions of both side walls of the gutter piece 6, recessed portions 6b, 6b having substantially the same cross-sectional shape as the cross-sectional shape of the portion from the deepest portion of the dew condensation water receiving portion 4 of the trough 1 to the water receiving wall 7 are formed. A hooking piece 6a that is elastically pressed against the upper edge of the water receiving wall 7 is provided in a protruding manner. The hooking piece 6a is slightly elastically deformed so that the recessed portion 6b,
When 6b is fitted from the deepest part of the dew condensation water receiving portion 4 to the water receiving wall 7 to the outer surface side thereof, the trough piece 6 is in a stable and stable state as shown in Fig. 5 due to the elastic restoring force of the hooking piece 6a. Can be attached to the gutter 1.

Further, in order to connect the lower part of the trough piece 6 to the valley of the trough 1, the curved surface portion 1b at the joint end of the trough 1 corresponds to about half of one side of the cross sectional shape (groove shape) of the trough piece 6. The L-shaped notch 8 is formed with a mouth width that allows water to pass through (3rd
Fig.), A trough piece 6 to a groove-shaped communication port 8'formed by combining two notches 8 and 8 of adjacent troughs 1 and 1.
The lower part of is inserted (Fig. 3).

Therefore, the dew condensation water 3 that has flowed down the inner surface of the seat 2 to the dew condensation water receiving portion 4 quickly falls from the water drop hole 5 and is received by the trough piece 6 and is guided into the trough 1 trough. is there.

By the way, the dew condensation water 3 guided to the valley of the trough 1 is guided to the ground through the downspout 20 provided at some places of the trough 1 along with the rainwater flowing into the trough to the ground. .

The position of the water drop hole 5 is not limited to the structure provided at the joint position of the trough 1. For example, the dew condensation water receiving portion 4 can be provided at any position in the longitudinal direction, and the gutter piece 6 is naturally attached to the position of the water drop hole 5.

Advantageous Effects of the Present Invention As described above in detail in connection with the embodiments, according to the drainage structure of the dew condensation water in the valley gutter of the multi-storey vinyl house according to the present invention, a large amount of water is accumulated on the inner surface of the sheet 2 of the vinyl house. Condensation water 3 that has been generated and dropped along the sheet 2 is positively received by the condensation water receiving portion 4 of the valley gutter 1 and is eliminated, so that there is no risk of it flowing down or dripping to other unexpected places. It is possible to eliminate various harmful effects caused by the flowing or dropping of the condensed water 3.

Moreover, the dew condensation water 3 that has flowed down to the dew condensation water receiving portion 4 of the trough 1 is quickly introduced from the water drop hole 5 through the trough piece 6 into the valley of the trough 1 so that the dew condensation water 3 of the dew condensation receiving portion 4 is large. It is possible to prevent adverse effects such as excessive accumulation and overflow, or accelerated rusting of the dew condensation water receiving portion 4 due to accumulated water for a long time.
