[Prior art]

 Conventionally, various types of vinyl sheet stretching devices have been proposed and used, and among them, a support frame having a dovetail-shaped cross section is said to be particularly excellent. In this method, a vinyl sheet is inserted into the dovetail groove of the support frame with a fixing corrugated wire having a trapezoidal part alternately connected to the left and right, and the vinyl sheets are placed on both left and right sides of the dovetail groove by the elastic force of the corrugated wire. It fixes by clamping. Since the fixing corrugated wire is cut to a fixed length (usually 2 m), a burr is formed at a cut end of the cut wire in many cases. For this reason, when a vinyl sheet is fixed in the dovetail groove of the support frame with the fixing corrugated wire, the vinyl sheet may be caught on the cut end of the fixing corrugated wire and may be broken. In many cases, it is necessary to partially replace and extend vinyl sheets.

[0003] Therefore, the proposals disclosed in Japanese Utility Model Publication No. 58-27639 and Japanese Utility Model Application Laid-Open No. 58-60009 cover both ends of a corrugated wire, and a vinyl sheet is caught on the end face of the corrugated wire. It is known that the coated portion is colored so that it can be easily identified when the corrugated wire is continued.

[0004] Further, a proposal disclosed in Japanese Utility Model Publication No. 4-25951 discloses that only the trapezoidal portion is covered with vinyl or the like except for both ends of the corrugated wire, and the trapezoidal portion is cut in half at both ends. A rectangular grip portion having one side formed to have the same length as the end portion, and a tubular portion protruding from the side portion at a side portion having the same length as the end portion of the rectangular grip portion. The tubular portion of the synthetic resin knob formed is inserted and inserted and attached until the corner of the rectangular gripping portion passes the bending point of the corrugated wire and touches the bending point. It is also known that a work piece that can be easily worked by holding a square grip portion when fastening to a support frame is known.

[0007] Further, as shown in FIGS. 6 and 7, the proposal disclosed in Japanese Patent Application Laid-Open No. 7-75451 discloses a method in which a film stopper 1 is formed of a pair of substantially Z-shaped side portions 3 and 3 made of vinyl chloride. The main body in which the opposite side edges are connected in the longitudinal direction by a central connecting portion 2 made of soft vinyl chloride is integrally molded, so that the film stopper material main body 1 can be easily formed into a W-shape as a whole. Bendable. The film stopper member body 1 is provided with a large number of stretchable pieces 4 which can be raised at regular intervals in the longitudinal direction. The extending piece 4 rises, and the folded film stopper member body 1 is sandwiched between the wing portions 6 and 6 of the film stopper member member 1 to extend in the width direction, and the both wings 6 and 6 are supported by the supporting frame for the vinyl house. 8, and the elastic piece 4 of the fixing corrugated wire 10 is inserted into the dovetail groove 9 of the support frame 8 while pushing down the stretched piece 4 in the rising state with the corrugated fixing wire 10. This is a method of fixing by pressing.

[0006]

[Problems to be solved by the invention]

 However, in all of the above devices, a fixing corrugated wire is used, and the trapezoidal portion of the corrugated wire clamps and fixes vinyl sheets on both the left and right sides of the dovetail groove. In the case of a material that stretches out, it is necessary to tighten the middle part of the arched structural material that is juxtaposed by a retaining band to prevent the wind during use, but this reduces the amount of sunlight transmitted. Problem.

Therefore, recently, a house using a polyolefin film has been proposed in order to further increase the amount of transmitted light in the house. Although there is an advantage that a stop band is not required, when a polyolefin film is used, the elasticity is not very good if it is partially clamped and fixed with the trapezoidal part of the corrugated wire rod attached to the left and right sides in the dovetail groove. Due to the poor quality, wrinkles are formed at portions of the film that do not come into contact with the fixing corrugated wire, and this causes a problem that the amount of transmitted sunlight decreases.

The present invention has been completed in view of the above circumstances. Even when a film having poor elasticity such as a polyolefin film is used, the film does not wrinkle and the amount of transmitted light in the house is not increased. A film fixing device for a greenhouse, which has a simple structure, does not damage the vinyl sheet during mounting and use with a simple structure, and is extremely easy to mount and remove, and a film used for the film fixing device. The purpose is to provide a fixing material.
