Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a wrapper for a vinyl house that fastens a vinyl sheet to the structural material of the greenhouse.
In particular, the present invention relates to a wrapper for a vinyl house that can securely fasten a thin vinyl sheet to a structural member having a circular cross section without damaging it.

[Conventional technology]

In recent years, forced cultivation of various vegetables, fruits, etc. has become popular, and the need for vinyl greenhouses has further increased. Things began to be invented.

For example, in an arch-shaped vinyl house, a simple and reliable fixing method for a soft vinyl sheet was proposed in Utility Model Application No. 1835-1983, in which the vinyl sheet is covered with a long structural member with dovetail grooves formed on the top. , a sheet is pushed into a dovetail groove and is locked from above by a corrugated wire rod with a synthetic resin protector equipped with a square gripping member attached to both ends;
- When installing a hard (thick) vinyl sheet on the framework of a greenhouse proposed in No. 98863, a receiving member is placed across a large number of purlin materials fixed to the framework, and the fixing member is The receiving member is fixed to the purlin material with bolts using the screw guide formed in the plate, and then a hard (thick) vinyl sheet is covered over the receiving member, and the upper opening provided in the channel member of the receiving member is fixed. A hard (thick) vinyl sheet can be used as a stopper by rotating and inserting a set screw through a long plastic stopper and elastically holding the set screw between the openings. There is something that locks between the receiving members.

On the other hand, in a simple greenhouse, an arch-shaped structural member 1 with a circular cross section as shown in Figure 6 is used.
The fasteners shown in FIGS. 7 to 9 have been used in the past when fastening the vinyl sheet 2 to the pillar 3 on the gable side or when fastening the vinyl sheet to the post 3 on the gable side.

This kind of patcher 5 has a cylindrical body made of vinyl chloride and has an arcuate cross section with a part cut out, and a vinyl sheet 2 is fastened to a vinyl house structural material 1 having an arched circular cross section. In this case, as shown in FIG. 7, when the vinyl sheet 2 is stretched over the structural member 1 and the wrapper 5 is pressed from above, the edges 5a, 5a of the notch of the wrapper 5 expand and the vinyl sheet 2 is stretched. While pressing the vinyl sheet 2 onto the structural material 1 as shown in FIG. 8, the wrapper 5 is fitted onto the structural material 1 as shown in FIG. 9.

In addition, the pair of thin steel plate packer bodies proposed by the present applicant in Utility Model Application Publication No. 64-22244 are each formed into a semi-cylindrical shape, and locking pieces are provided at each joint of the pair of bodies in a staggered manner. A concave portion is formed at the base of the locking piece protruding from one body to engage with the base of the locking piece protruding from the other body and holding the locking piece so as to be rotatable with respect to the other body. There is a fastener in which a sheath tube that is attached to the stopper piece and tightens the pair of bodies together is removably inserted into each stopper piece.

Furthermore, the fixing clip disclosed in Japanese Utility Model Application Publication No. 53-52241 has a pair of clamping pieces having an arcuate inner wall surface and a pair of operating pieces having a V-shaped cross section and an inward engaging groove. A short wedge member having a handle is fitted into the engagement groove.

[Problem that the invention seeks to solve]

However, when the above-mentioned conventional wrapper 5 is fitted onto the structural member 1, it is expanded while sliding on the vinyl sheet 2, so the edge 5a of the wrapper 5,
There was a drawback that the vinyl sheet 2 could be damaged or damaged due to the shape of 5a or poor quality of the product.

In particular, in recent years, there has been a strong tendency to place emphasis on forced cultivation in greenhouse cultivation, and for this reason, thin vinyl sheets that allow sufficient sunlight to pass through are often used, so the vinyl sheets are easily damaged when tightening the pads. , has become a serious problem.

Furthermore, in the fixing clip disclosed in the above-mentioned Japanese Utility Model Publication No. 53-52241, the hinge portion is formed by integral molding of hard synthetic resin, and the edges are also made of hard synthetic resin, so the sheet When tightening objects, especially thin vinyl sheets, there is a drawback that the vinyl sheets are damaged or damaged at both ends of the clamping pieces due to insufficient expansion. Furthermore, since the wedge member is a short piece that is shorter than the clip, the clamping force is biased, and the vinyl sheet has the disadvantage that it easily falls off when it is blown by wind or the like.

The present invention was devised in view of the above circumstances, and the purpose is to provide a cover that has a simple structure and does not cause damage to the vinyl sheet of a greenhouse when fastening the thin vinyl sheet. .

[Means for solving problems]

In order to achieve the above object, the present invention provides a plastic house wrapper for fastening a vinyl sheet to the structural material of a plastic house, in which a pair of hard synthetic resin wrapper bodies are each formed into a semi-cylindrical shape, and the semi-cylindrical A soft synthetic resin edge piece is formed on the lower edge of the body, while a locking piece is formed by extending upwardly from the upper edge of the semi-cylindrical body of the packer body to form an inwardly curved locking piece. At the lower part, the pair of packer bodies are expandably connected by a soft synthetic resin, and
A wedge body having approximately the same length as the packer body is removably engaged between the locking pieces.

[Effect]

Next, to explain the operation of the present invention, a vinyl sheet is stretched over the structural material of a vinyl house with a circular cross section, and when the pair of engaging pieces are pinched and the Patsuka main body is pressed against it, the Patsuka main body expands. In this state, the soft synthetic resin edge at the lower edge slides on the vinyl sheet, and while pressing the vinyl sheet against the structural member having a circular cross section, the packa main body is fitted into the structural member.
Thereafter, the wedge body is locked between the pair of locking pieces, and the packer body can be securely fastened without damaging the vinyl sheet.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.
