Description

Description: TECHNICAL FIELD The present invention relates to a method of manufacturing a house curtain in a greenhouse, which is hung above an upper part of the greenhouse to effectively protect the cultivated crop from heat and shade. It is provided for use.

(Prior Art) Conventionally, in a greenhouse made of glass, vinyl, or the like, in order to efficiently keep cultivated crops warm or to shield light, a transparent or light-shielding heat-insulating curtain or light-shielding material is provided at the upper part of the house room. A curtain (hereinafter referred to as a house curtain) is stretched and suspended, and of course, it has a two-shaft, two-layer structure, that is, its drive system and curtain structure are doubled, so that it is kept warm during cold season and at night. It deals with the effects and the light-shielding effects in summer and during the daytime.

(Problems to be Solved by the Invention) However, in order to form the house curtain into a two-axis two-layer structure, not only the number line must be doubled in accordance with that, but also the house curtain is placed above the greenhouse. A manual winch device or a motor-driven winch device for winding up a house curtain to the side of a greenhouse or a winch device driven by a motor, and its ancillary equipment, etc. Therefore, it is difficult to say that a conventional two-shaft two-layer house curtain is necessarily efficient in terms of a device. Of course, by winding the house curtain on one winding shaft and storing it, or by winding the winding cord connected to the leading end of the wound curtain on the other winding shaft, When the house curtain is deployed to the upper part of the house, the house curtain is subjected to a repetitive pulling force, and the more frequently it is performed, the more the local tension acts and the more it is broken. It often causes adverse effects such as tearing, and often requires repair of the damaged portion or replacement with a new curtain in a relatively short period of time.

Therefore, one of the applicants of the present invention is to provide a heat-insulating sheet having an air-filled structure (a light-shielding sheet is also acceptable) formed as shown in FIGS. 5 to 9 of Japanese Utility Model Application Laid-Open No. 62-91950. By proposing a means to be stretched and hung above the upper part, it not only achieves the same heat retention effect as in the case of a two-shaft, two-layer house curtain, but also simplifies auxiliary facilities. We have come up with a device that can contribute.

However, a large number of tube-shaped air layers are formed at intervals on such a long sheet member, and, of course, a mat body having an air-filled structure that requires a sufficient width in the left-right width direction,
It is difficult to manufacture the device in a simple and inexpensive manner as a device, and as a transitional means until its practical use, it has been desired to develop a means for relatively easily producing and installing a house curtain on site.

(Means for Solving the Problems and Their Functions) Therefore, in view of the above-described circumstances, the present invention considers the above-described circumstances, and the side trunk portions of the flat tubular duct tubes T1 to Tn near the front and rear ends in the longitudinal direction. The communication port 16 is drilled, the position of the communication port 16 of the adjacent duct tubes T1 to Tn, i.e., the outer peripheral edge of the perforated position located inside the entire communicating duct tube is superposed on the front and back, and bonded. The outer peripheral edge of the perforated position is pinched by the clipping tools B and 17, and a large number of the duct tubes T1 to Tn are connected so that air can freely communicate in the left-right width direction, and the upper edges of the duct tubes T1 to Tn are connected.

(Manufacturing method) Next, a procedure for manufacturing a required house curtain using the above-described duct tube T, the clamping tool B and the like will be described.
First, the duct tube T is stretched flat so that the side trunk portion with the perforated mark 1 is turned to the front side, and a perforation operation for cutting the inner inner peripheral portion of the perforated mark 1 indicating a perforated portion is performed thereon.

In this case, the duct tube T ₁ of the base end portion configured to lateral sides of the room house H, for the duct tubes T _n of the central upper portion configured tip greenhouse house H, flat tubular duct Inside the tubes T ₁ , T _n , after inserting an appropriate plate etc. so that the cut is not made in the back side trunk,
The cutout is cut into a rectangular mouth with the cutout edge of the inner peripheral portion of the perforated mark 1 displayed on the front side body part as a guide.

Further, the duct tube T _1, defined between T _n duct tube T ₂ ~T _n-1 (hereinafter, referred to as an intermediate portion of the duct tube) in the case of the inner inner peripheral portion of the perforated marks 1 As shown in FIG. 6, the front and back sides are cut at the same time based on the cut edge.

If this intermediate portion of the duct tube T ₂ through T _n-1, in principle or cut simultaneously processed sides one by one in a facility site or the like, substantially the same position several sheets of duct tube T ₂ through T _n-1 It is dealt with by cutting and processing at once.

Of course, these duct tubes T _{1 to} T _n are housed at room temperature H
Perforated mark 1 at an appropriate length depending on the length in the longitudinal direction, for example, after cutting first at about 50 m, and at a position of about 50 cm to 1 m from the front and rear openings in the longitudinal direction.
As described above, several or more pieces are prepared as one set according to the roof width of the house.

For example, a house 1 having a double flow roof structure as shown in FIG.
If the width of the building is about 6m and the width of the house curtain per body is about 3m, the tube width of the duct tube T will be
About 45cm to 50cm, about 10 pieces per side, about 20 pieces per building are required, and if it is a double building, about 40 pieces are needed in total.

Next, the duct tubes T _1-
The T _n, the coupling connected to the left-right width direction is performed in a state where the flat installed in the longitudinal direction as shown the duct tube T ₁ through T _n in Figure 7.

First, the surface outer peripheral portion of the perforated portion having an opening formed on one side of the duct tubes T _1, stuck peel off one side of double-sided adhesive tape 15, overlapped back surface of the perforated portion of the duct tube T ₂ of the next order thereon The work of peeling off and adhering the other side of the double-sided adhesive tape 15 is performed for each of the perforated portions formed in the longitudinal direction, whereby the duct tube T ₁ and the duct tube T ₂
Is connected so that air communication is possible.

Then, the surface peripheral surface of the perforated portion in the duct tube T ₂ of the next order, again after having adhered the double-sided adhesive tape 15, is deposited stuck on superimposed as in the successive positions of the duct tube T ₃ continue working like, further, the performs repeatedly from the duct tube T ₂ toward the duct tube T _n-1 which, in its end, the double-sided adhesive tape on an outer peripheral surface of the perforated portion of the duct tube T _n-1 15 on which the perforated portion of the last duct tube T _n is superimposed as a back surface, and by pasting them, the duct tube T ₁ at the base end to the duct tube T at the distal end are attached. _n is configured so that air can freely communicate in the left-right width direction.

By affixing superimposed perforated portion of the duct tube T ₁ through T _n as the communication port 16 formed by opening in a rectangular shape therebetween the duct tube T ₁ through T _n of these things is formed Is done.

However, only by sticking with double-sided adhesive tape 15,
The connection strength may be lacking.

Therefore, after stuck by superimposing a perforated portion processed into a position closer to the front and rear end opening portions of the longitudinal direction of the duct tube T ₁ through T _n as above, the peripheral portion of the connecting portion, FIG. 2 5. The holding member 17 having a leaf spring function as outlined in FIG.
The clip B is cut in accordance with the inner width in the vertical and horizontal directions of 16 and the clamp B is folded in two with the peripheral portion of the connecting portion facing between the left piece 4 and the right piece 6 of the clamp B. In this case, the connection strength of the communication port 16 is clamped to a strong one.

Note that the above-described bonding operation, the operation of clamping the clamping piece 17, or the fixing operation with the clamping tool B are performed by the duct tube T1.
It is performed by inserting both hands or one hand as needed from the ends of ~ Tn.

Of course, the duct tubes T1 to Tn are formed extremely long,
In the case where the communication port 16 must be formed also in the central portion in the longitudinal direction, the duct tube T1 at the base end or the distal end is used.
One of Tn to Tn may be perforated on both the front and back surfaces, and after the internal pinching operation or the like is completed, the periphery of the last perforated portion may be sealed by separately attaching a sheet material of the same quality.

Next, the left piece 4 and the right piece 6 of the clipper B cut to an appropriate length face the portion of the hanging mark 2 displayed on the upper edge of the duct tube T, and the hanging of the clipper B is performed. 14
The lower lever 14b faces the concave portion 8 of the clamp B in the opened state, and then the clamp B is folded in two. the upper edge of the duct tube T ₁ through T _n is engaged sandwiched by bullets設嵌between the fitting凹爪7.

Furthermore, among the duct tube T ₁ through T _n, except one or both of the front and rear open ends of the longitudinal duct tube T ₁ which is disposed at the proximal end portion, the front and rear of all of the longitudinal The openings are closed by tightly binding the openings at both ends with a string or the like.

(Construction process of house curtain) A house curtain is usually manufactured at a construction site or the like by the above-mentioned procedure. To extend and support a number of guide wire rods 9, and when the guide wire rod 9 is stretched, a ring such as a coil spring is used.
The guide rollers 11 which suspend the guides 13 are inserted and supported at the same time.

Of course, the pitch of the guide wire rod 9 is disposed on substantially the same as the attachment spacing of the clamping device B which is attached to the upper edge of the duct tube T ₁ through T _n, also inserted into the guide wire rod 9 The guide roller 11 thus gathered is naturally located at the upper side portion of the room temperature house H at the inclined lower end of the guide rod 9.

After this the guide roller 11 ring 13 which is hung on, through the upper rod 14a of the duct tube T ₁ through T _n of the upper edge clamping device is attached to the portion hanging-held connecting bar 14 B support By doing
These duct tubes T _{1 to} T _n are suspended from the greenhouse house H in a state of being folded at the upper side portion.

Then, among the duct tube T ₁ through T _n of these things, a proximal end,
That is, the distal end portion 18a of the supply / exhaust tube 18 is inserted from one or both of the front and rear or both of the duct tube T ₁ (the duct tube near the base end) disposed at the lower end portion. Then, the ends are closed by binding.

S is an air supply / exhaust blower which is installed at an appropriate place of the greenhouse H, and its air supply / exhaust port is connected to the base end portion 18b of the pipe 18 to form a pipe.

The duct tube T manufactured as described above and attached to the greenhouse H is usually constructed by appropriately switching between a heat insulating material and a light shielding material in accordance with winter, summer and the like.

And Thus (operation method of the house curtain) and actuates the blower S to supply air to the duct tube T ₁ of the proximal end, the most, the air in the earliest is the duct tube T _n of the tip that is not working with its own weight the fed and with膨成pushes gradually along the duct tube T _n to the guide wire rod 9. Next, the next adjacent duct tube T
_n-1 is gradually extruded while expanding, and the above-described phenomenon works one after another. As a result, the entirety of the duct tubes T _{1 to} T _n is gradually self-propelled, and the duct tube T is placed above the greenhouse H. ₁ through T _n is operated expansion, house curtain air-filled structure as shown in FIG. 1 is constituted by this.

In the above case, as a practical matter, the duct tube T ₁
Although the leakage phenomenon of some air from the through T _n are those inevitable that occurs, and actuated a blower S always either continue a weak air blowing into the duct tube T ₁ through T _n, or, It suffices to respond by intermittently operating the blower S to supply air. Wherein Conversely, a is the exhaust air actuating a blower S, most are from the duct tube T ₁ of the base end portion that is working with its own weight, will be air earliest is exhaust air is reverse drawn,
This said duct tube T ₁ is folded is narrowed at.

Then, adjacent exhaust air phenomenon from the duct tube T ₂ of the next order happened acts phenomena such as pressing down gradually along the duct tube T ₂ to the guide wire rod 9, which is all of the duct tubes T ₁ ~ Work on T _n sequentially.

And to such, while sequentially exhaust air by folding from the duct tube T ₁ of the base end portion to the duct tube T _n of the tip portion,
By gradually running the entirety of these duct tubes T _{1 to} T _{n on} their own, the upper part of the greenhouse H is released and the duct tubes T
T _{1 to} T _n are folded and stored.

(Effects of the Invention) As described above, the present invention provides a flat tubular duct tube T1.
A communication port 16 is formed in the side trunk near the opening at the front and rear ends in the longitudinal direction at ~ Tn, and is located at the position of the communication port 16 of the adjacent duct tubes T1 to Tn, that is, located inside the whole of the connected duct tubes. the outer periphery of the punching position superimposed sides and bonded, air outer peripheral edge portion of the punching position pinched by clamping members B, 17, a large number of the duct tube T ₁ through T _n, in the left-right width direction Connect freely so that the duct tube
Since the method of manufacturing the house curtain is such that the upper edges of T _{1 to} T _n are sandwiched by the holding fixture B, the width and the length in the longitudinal direction of the greenhouse H at the facility site or the like. Depending on,
The user himself can produce it relatively easily and can expect great versatility.

In addition, a perforated mark 1 indicating a perforated portion for allowing the duct tube to communicate with the air in the width direction is displayed on a side trunk portion of the duct tube integrally molded in a flat cylindrical shape,
The upper edge of the duct tube T may be a duct tube for a house curtain which displays a hanging mark 1 indicating a hanging point for hanging the duct tube T in the longitudinal direction. Is not only useful as a stand-alone product, but also the perforating process based on the perforated mark 1 and the hanging mark 2 and the mounting operation can be performed extremely easily and quickly, and the usefulness in use is extremely remarkable. And other effects.
