Description

[Detailed explanation of the invention] [Industrial application field] This invention is attached to the frame of a greenhouse,
This invention relates to improvements in receiving members for holding hard and soft (thick) vinyl sheets.

[Conventional technology]

In recent years, there has been proposed Utility Model Application No. 1835-1983 by the present applicant as a simple and reliable fixing means for soft vinyl sheets when constructing greenhouses and the like.

This involves covering a long square structural member (rafter) with a dovetail groove on the top with a soft vinyl sheet, pushing the sheet into the dovetail groove, and attaching a synthetic resin protector with a square grip from above to both ends. It is secured by the attached corrugated wire.

In this way, the fixing means for soft (thin) vinyl sheets has become quick and reliable, but on the other hand, the fixing means for hard and soft (thick) vinyl sheets are shown in Figures 8 and 9. Only what is shown is known.

A conventional seat locking receiving member P is made by bending both left and right sides of a bottom portion 1 of a strip-shaped thin steel plate upward to form both side portions 2 and 2a to form a substantially triangular channel portion 3. A tube 4 is formed on the upper edge, and screws 6 for fixing a hard and soft (thick) vinyl sheet 5 are inserted into the gap between the two tubes 4 and 4 via an aluminum stopper 7, and the elasticity of the channel member 3 is The fixing screw 6 was held between the tubes 4 and 4 by force, and the thick vinyl sheet was locked.

[Problem that the invention attempts to solve]

However, the above-mentioned conventional sheet receiving members cannot be directly screwed to the main building material that serves as the framework of the greenhouse, and workability is poor.
For example, a fixing metal fitting 8 as shown in FIG. 9 was required.

That is, one side 2 of the hard and soft (thick) vinyl sheet receiving channel member 3 is held down by one side 9 of this fixing metal fitting 8, and the elongated hole 11 bored in the folded piece 10 on the opposite side is held down. C type steel 12
By inserting the fixing bolt 13 into the C-shaped steel 12 and screwing it into the C-shaped steel 12,
0, the other side 2a of the channel member 3 is pressed and fixed as shown in FIG. The properties were poor, and there were also problems with durability.

The present invention was devised in view of the above circumstances, and has a simple structure, is extremely easy to install and fasten, has good workability, and is strong and durable for long-term use. The purpose of the present invention is to provide a receiving member for retaining a soft (thick) vinyl sheet.

[Means for solving problems]

In order to achieve the above object, the present invention bends the left and right sides of a strip-shaped thin steel plate upward to form a nearly triangular channel member, and attaches an elastic set screw for securing a hard vinyl sheet to the upper part of the channel member. forming an opening having a gap capable of holding the channel member, folding both end edges outward from each other, and extending one folded edge of the channel member to form a fixing member;
The end edge of the fixing member is folded back inward, the bottom of the fixing member is formed on the same plane as the bottom of the channel member, and a screw guide is formed on the top surface of the fixing member.

[Effect]

Next, to explain the operation of the present invention, when installing hard and soft (thick) vinyl sheets on the frame of a greenhouse, the receiving member according to the present invention spans a large number of purlin materials fixed to the frame. is mounted, and the receiving member is fixed to the purlin material with bolts using the screw guide formed on the fixing member. Next, cover the receiving member with a hard and soft (thick) vinyl sheet, and twist and insert the set screw into the upper opening provided in the channel member of the receiving member through the long plastic stopper. Hard and soft (thick)
A vinyl sheet is secured between the stopper and the receiving member.

In this way, the vinyl sheet receiving member can be easily fixed to the main building material, and hard and soft (thick) vinyl sheets can be stretched extremely quickly.
Moreover, it is possible to do it robustly.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Figures 1 to 3 show an embodiment of the present invention, in which a large number of C-shaped steels 14, which are the main building material of greenhouse A, are arranged side by side to form the frame of greenhouse A, and a large number of them are installed side by side. Hard and soft (thick) vinyl sheet receiving members 15 are placed directly on top of the C-shaped steel 14 and fixed with screws.

The receiving member 15 is made by bending the left and right sides of the bottom part 16 of a strip-shaped thin steel plate upward, and forming both side parts 17, 17.
a to form a substantially triangular channel portion 18, and the upper edges of both side portions 17, 17a are folded back to the outside to form folded pieces 19, 19a, and a plastic greenhouse is placed over the gap between these two folded pieces 19, 19a. Place the hard and soft (thick) vinyl sheets 20 to be stretched on A, place the long aluminum stopper 21 on top of it, and twist the set screws 22 from above to open the openings of the folded pieces 19, 19a. Insert into gap Q.

On the other hand, one folded piece 19a of the receiving member 15
extends along the outside of the side portion 17a to form a fixing member 24 having a bottom surface 23 similar to the bottom surface 16 of the channel member 18, the end edge 25 of which is folded back inward. Therefore, the triangular channel member 1
8 and the bottom surface 23 of the fixing member 24 can be placed on the same plane.

Note that if the width of the conventional dovetail-shaped long rectangular structural member (support frame) for soft vinyl sheets is made to be the same as the width of the receiving member of this embodiment, the frame of the already described vinyl house can be formed. Hard and soft (thick) vinyl sheets can be easily replaced without changing the material.

Further, a screw guide 26 is provided on the upper surface of the fixing member 24.
Since this is provided, the receiving member 15 can be easily fixed to the C-shaped steel 14 of the purlin material with the set screw 27.

Furthermore, the receiving member 15 of this embodiment fixed to the main building material in this way transfers water droplets condensed inside the greenhouse to the channel member 18 and the fixing member 24.
It is also possible to discharge to the side of the house.

[Effect of idea]

According to the above-mentioned present invention, a fixing member is formed by extending one folded edge of a substantially triangular channel member, the bottom of the fixing member is formed in a plane equivalent to the bottom of the channel member, and a screw is attached to the top surface of the fixing member. Since the guide is provided, there is no need for separate fixing hardware to fix the seat locking receiving member to the house, and it is possible to easily fix it to the frame member of the house. By folding it back, condensed water inside the greenhouse can be drained to the side, preventing root rot of cultivated plants.

Further, since both edges of the upper opening of the triangular channel member are folded outward, the channel member has sufficient elasticity to hold the set screws that lock the hard and soft (thick) vinyl sheets.
