BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film fixing method and apparatus for a vinyl house for fixing a polyolefin film sheet or the like to a film sheet supporting frame in a vinyl house or the like with a corrugating wire for fixing through a film stopper. In particular, the present invention relates to a film fixing method for a vinyl house, which can surely fix a polyolefin-based film sheet without damaging it, and does not cause wrinkles on the film sheet, and can be used as a house for a long time, and a film stopper used in the method.

2. Description of the Related Art Conventionally, various vinyl sheet tensioning tools have been proposed and used, but among them, a support frame having a dovetail-shaped cross section is said to be particularly excellent. This is done by inserting a vinyl sheet into the dovetail groove of the support frame with corrugated wire rods for fixing in which the trapezoidal parts alternate alternately on the left and right, and the elastic force of the corrugated wire rod sandwiches the vinyl sheet on both the left and right sides of the dovetail groove. It is pressure-fixed. Since the corrugated wire for fixing is cut into a fixed length (usually 2 m), a burr is often formed at the cut end and is sharp. For this reason, when the vinyl sheet 4 is fixed in the dovetail groove of the support frame with the fixing corrugated wire, the vinyl sheet may be caught at the cut end of the fixing corrugated wire and may be torn. It is often necessary to partially replace and stretch the vinyl sheet as it tears away.

Further, since the fixing corrugated wire is cut to a certain length, for example, when fixing the original sheet of the vinyl sheet in the dovetail groove of the support frame long along the rafters or purlins of the vinyl house. In order to fix the vinyl sheet, the corrugated wire rod must be continuously fixed. In this case, if the end of the corrugated wire is wrapped, the vinyl sheet can be halved and damage can be reduced.Therefore, the end of the corrugated wire is always wrapped, but in actual work, the vinyl sheet should be wrapped. The wrap length of the end of the corrugated wire rod is one peak, two peaks, or one peak because it is necessary to quickly stretch and fix it and it is difficult to check the length of the wrapped end. It is half of the above and is not constant. Also, Japanese Utility Model Publication No. 58-27639 and Japanese Utility Model Publication 58-60.
In the proposal disclosed by Japanese Patent No. 009, both ends of the corrugated wire are covered so that the vinyl sheet is not caught by the end faces of the corrugated wire and is not torn, and when the corrugated wire is continued by coloring the covering, it is easy to identify. There is something like this.

In the proposal disclosed in Japanese Utility Model Publication No. 4-25951, only the trapezoidal portion except the both end portions of the corrugated wire is covered with vinyl or the like, and the trapezoidal portion is cut in half to have one side. A synthetic resin having a rectangular grip portion formed to have the same length as the end portion, and a tubular portion formed on the side portion formed to have the same length as the end portion of the square grip portion so as to project from the side portion. The tubular part of the knob made of metal is inserted, and it is inserted and attached until the corner of the rectangular gripping part touches the bending point after passing the bending point of the corrugated wire rod, thereby fastening the vinyl sheet to the support frame. In some cases, there is something that can be easily worked by holding the rectangular grip.

[0005]

However, since the conventional corrugated wire for fixing is simply cut at both ends, it is pressed into the dovetail groove of the supporting frame to fix the original material of the vinyl sheet. When stopping, the vinyl sheet may be damaged by the both ends, or after the sheet is fixed,
There is a drawback in that the vinyl sheet is blown by the wind and is also torn from both end portions of the corrugated wire rod. Further, since the corrugated wire is a steel wire of about 2 m and is used to settle in the dovetail groove of the support frame by utilizing its elasticity, there is a problem that there is a risk of scratching the face and eyes during the work. It was

Further, the fixing corrugated wire rods proposed in Japanese Utility Model Publication No. 58-27639 and Japanese Utility Model Application Laid-Open No. 58-60009 also have coatings on both ends, so that both ends can be easily identified. Although it is convenient to easily keep the length of the wrapping edge constant, it is not possible to completely prevent damage to the vinyl sheet at both ends of the corrugated wire rod. When removing from the dovetail, it is necessary to pry it off with a screwdriver or the like, which is very troublesome and requires a special technique as in the case of the conventional example. Furthermore, the above-mentioned corrugated wire rod is exposed to wind and rain during use to cause rust, and when the vinyl sheet is fanned by wind or the like, the portion in contact with the corrugated wire rod of the vinyl sheet is damaged due to the rust, It had the drawback of breaking from there.

Furthermore, the corrugated wire for fixing disclosed in Japanese Utility Model Publication No. 4-25951 can completely prevent the vinyl sheet from being damaged, and the tubular portion ensures that the vinyl sheet is secured to the corners of the dovetail groove of the support frame. Can be fastened to
In addition, since the rectangular grip does not stick out from the end surface of the corrugated wire, it does not get caught and damages the vinyl sheet, and there is no rust on the trapezoidal part where the vinyl sheet of the corrugated wire is fastened during use. It is possible to completely prevent damage to the vinyl sheet, and especially when replacing a fixed vinyl sheet, you can easily pull out by pulling the square grip and pull it out directly, but the trapezoidal part of the corrugated wire directly. Since it fixes the vinyl sheets to the left and right sides in the dovetail, it is used in the case of easily stretchable materials such as vinyl sheets, during use, the middle part of the arch-shaped structural material juxtaposed by the retaining band. However, there is a problem that the amount of sunlight transmitted decreases.

Therefore, recently, a house using a polyolefin film has been proposed in order to further increase the amount of transmitted light in the house. However, this polyolefin film has a large amount of transmitted light of sunlight, and it is Although there is an advantage that a stop band is not necessary, when using a polyolefin film, if the trapezoidal part of the fixing corrugated wire rod is partially fixed on the left and right sides in the dovetail, the stretchability is not very good. In addition, wrinkles are generated in a portion of the film that is not in contact with the fixing corrugated wire, and the amount of transmitted light of sunlight is reduced.

The present invention has been completed in view of the above circumstances, and even if a film having a poor stretchability such as a polyolefin film is used, wrinkles do not occur in the film and the amount of transmitted light in the house is increased. The film fixing method for a vinyl house and the film stopper used in the film fixing method are simple and easy to install and remove, with a simple structure that does not damage the vinyl sheet at all during installation and use. The purpose is to provide wood.

SUMMARY OF THE INVENTION The present invention provides a film fixing method for a vinyl house in which the film sheet is pressure-fixed by the elastic force of the fixing corrugated wire rod in the dovetail groove of the supporting frame for the vinyl house to achieve the above object. In the method
After arranging the polyolefin film sheet on the vinyl frame supporting frame, the film sheet is pushed into the groove of the supporting frame by the W-shaped bent film stopper, and then in the longitudinal direction of the film stopper. After sandwiching the polyolefin-based film sheet in the groove by launching a large number of spread pieces and spreading the film stopper in the groove, the corrugated wire for fixing is attached while pushing down the spread pieces. A method for fixing a film for a vinyl house, characterized in that a polyolefin film sheet is pressure-fixed on both sides in the groove via the film stopper by elastic force of the corrugated wire for fixing, and the film fixing method. Film stopper material body made of vinyl chloride connected by a central connecting part made of soft vinyl chloride used for Foldable to form the W-shaped, and a film sealing material which is characterized in that arranged a number while maintaining a constant interval stretched piece which can rise to the film stopper material body in the longitudinal direction.

[0011]

Next, the operation of the present invention will be described. After the polyolefin film sheet is placed on the dovetail groove of the support frame for the vinyl house, the film is placed in the groove of the support frame by the W-shaped film stopper. The film sheet is pushed in, and then a plurality of spreading pieces arranged in the longitudinal direction of the film stopping member are respectively raised, and both inner surfaces of the film stopping member are pushed by both side surfaces of the expanding piece and bent into a W shape. Spread the film stopper in the groove. By this operation, the polyolefin film sheet is temporarily held between the film stopper and the inner surfaces of both sides of the dovetail groove. Then, while pushing down the stretched piece in the rising state with the fixing corrugated wire, the fixing corrugated wire is attached to both corners of the film stopper from the leading end of the fixing corrugated wire, and is supported by the elastic force of the fixing corrugated wire. Polyolefin film sheets are sequentially pressure-fixed to the inner surfaces of both sides of the dovetail groove formed on the frame via film stoppers. Finally, when the corrugated wire rod reaches the terminal end, the end portions are similarly pushed into both corners of the film stopper, and the mounting of one corrugated wire rod is completed. Furthermore, when continuously mounting the corrugated wire, push it so that the tip of the next corrugated wire is positioned on the opposite surface of the film stopper in the dovetail groove facing the end of the corrugated wire,
Repeat the same procedure below.

As described above, during the fixing operation of the film sheet, the resistance increases due to the elastic force of the wire material toward the end of one corrugated wire material, and it is difficult to push the end part, which may damage the film sheet. However, since the corrugated wire for fixing is attached through the film stopper, damage to the film sheet can be completely prevented, and wrinkles do not occur on the polyolefin film sheet during use, so the amount of transmitted light in the house is reduced. Further, the film stopper can completely prevent the damage of the film sheet due to the generation of rust from the corrugated wire. Also, when replacing the fixed film sheet, the film stopper and the film sheet can be easily and quickly removed by picking out both ends of the corrugated wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the film fixing method for a greenhouse according to the present invention and the film stopping material used therefor will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which a polyolefin film sheet is fixed to a supporting frame for a vinyl house using the film stopper of this embodiment, and FIG. 2 is a drawing of the spreading piece of the film stopper of this embodiment. FIG. 3 is an explanatory view showing a state where the film stopper of the bent embodiment is inserted into the vinyl house support frame, and FIG. 4 is a perspective view showing the state where the film stopper of the embodiment is inserted into the vinyl house support frame. FIG. 5 is a perspective view showing a state in which the film stoppers are inserted and the stretched pieces of the film stoppers are respectively raised to temporarily hold the film stoppers on the support frame. FIG. 5 is a side view of the film stopper of the embodiment. It is a figure.

As shown in the drawing, the film stopper 1 of this embodiment has a pair of substantially Z-shaped vinyl chloride side portions 3, 3 whose opposite side edges are longitudinally made of soft vinyl chloride. The main body in a state of being connected by the connecting portion 2 is integrally molded, so that the whole film stopper material main body 1 can be easily bent into a W shape. The film stopper main body 1 is provided with a large number of extension pieces 4 that can be started up at a constant interval in the longitudinal direction.
Further, the spreading piece 4 has recesses 5 and 5 symmetrically provided on both sides, and when the spreading piece 4 stands up, the neck portions 6 and 6 of the film stopper material body 1 are clamped to bend the film stopper. The material body 1 is stretched in the width direction and temporarily held in that state. Reference numeral 7 is a small hole formed in the film stopper material main body 1 in order to make it easier to start the spreading piece 4 by hooking it with a nail.

Next, by using the film stopper 1 of this embodiment, the polyolefin-based film sheet 11 is pressure-fixed by the elastic force of the corrugated wire rod 10 for fixing in the dovetail groove 9 of the support frame 8 for a vinyl house. Explaining the method, the dovetail groove 9 of the support frame 8 for the greenhouse.
After arranging the polyolefin film sheet 11 thereon, the film sheet 11 is pushed into the groove 9 of the supporting frame 8 by the film stopper 1 bent into a W shape, and then a large number of film stoppers 1 are formed in the longitudinal direction of the film stopper 1. The spread pieces 4 thus arranged are respectively raised, and the inner surfaces of both sides of the film stopper are pushed by the both side surfaces of the spread piece 4, so that the recesses 5 and 5 formed on both sides of the stretch piece 4 are removed from the main body 1 of the film stopper. Film stopper 1 bent into a W shape with the necks 6 and 6 held in between
Is spread in the dovetail groove 9. By this operation, the polyolefin film sheet 11 is temporarily held between the film stopper 1 and the inner surfaces of both sides of the dovetail groove 9. Then, while pushing down the stretched piece 4 in the rising state with the fixing waveform wire 10, the fixing waveform wire 10 is attached to both corners of the film stopper 1 from the tip end portion of the fixing waveform wire 10. The polyolefin-based film sheet 11 is sequentially fixed to the inner surfaces on both sides of the dovetail groove 9 formed in the support frame 8 by elastic force through the film stopper 1 until the end of the corrugated wire 10 is reached. Similarly, the film stopper 1 is pushed into both corners to complete the mounting of one corrugated wire. Further, when continuously mounting the corrugated wire, push it so that the tip of the next corrugated wire is located on the opposite surface of the film stopper in the dovetail groove facing the end of the corrugated wire, and perform the same work below. Repeat.

As described above, during the fixing operation of the film sheet, the resistance increases toward the end of one corrugated wire 10 due to the elastic force of the wire, which makes it difficult to push the end, which is dangerous. If a corrugated wire rod with knobs having square grips at both ends is used, it is safe and easy to push the end portion, and the corrugating wire rod 10 for fixing is mounted via the film stopper 1. Therefore, the film sheet 11 can be completely prevented from being damaged, and the amount of transmitted light in the house can be further increased because the polyolefin-based film sheet 11 is not wrinkled at all during use, and the film sheet 11 due to the generation of rust from the corrugated wire rod 10 The film stopper 1 also completely prevents the damage. Also, when replacing the fixed film sheet,
By pulling out the knobs attached to both ends of the corrugated wire rod, the film stopper and the film sheet can be easily and quickly removed.

Further, by using this embodiment, the polyolefin film sheet 11 is securely clamped between the inner surfaces of both sides of the film stopper 1 and the dovetail groove 9, so that the preparatory work for attaching the film sheet can be carried out quickly. I can do it. And

According to the present invention described above, after the polyolefin film sheet is placed on the dovetail groove of the support frame for the vinyl house, it is placed in the groove of the support frame by the W-shaped film stopper. By pressing the film sheet and then raising a plurality of spreading pieces arranged in the longitudinal direction of the film stopper, the film stopper bent in a W shape can be easily spread in the groove,
Therefore, the polyolefin film sheet is securely held between both inner surfaces of the film stopper and the dovetail groove, so that the preparation work for mounting the film sheet can be performed quickly. Then, in the state in which this preparatory work is completed, the fixing corrugated wire is mounted in the groove while pushing down the spreading piece that has risen with the fixing corrugated wire. It is easy to do, and the elastic force of the corrugated wire for fixing is used to sequentially press the polyolefin film sheet at both corners of the dovetail groove formed on the support frame through the film stoppers. The polyolefin film sheet can be reliably fixed on both inner surfaces of the sheet without generating wrinkles. In addition, since the corrugating wire for fixing is attached via the film stopper as described above, damage to the film sheet can be completely prevented.

Further, since the film stopping material is interposed, wrinkles do not occur at all in the polyolefin-based film sheet which is not very stretchable even during use, so that the amount of transmitted light in the house can be further increased. Damage to the film sheet due to generation of rust from the corrugated wire can be completely prevented by the film stopper. Further, even when the fixed film sheet is replaced, the film stopper and the film sheet can be easily and quickly removed by picking out both ends of the corrugated wire.
