Description

[Detailed description of the invention] [Field of industrial application] The present invention is a dovetail support frame for fixing sheets in an arch-shaped vinyl greenhouse to catch and drain condensed water inside the greenhouse. This invention relates to a condensation water receiving member for a vinyl greenhouse.

[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 vinyl sheets when constructing greenhouses and the like.

This is a corrugated structure in which a long rectangular structural material with a dovetail groove formed on the top is covered with a vinyl sheet, the sheet is pushed into the dovetail groove, and a synthetic resin protector with a square grip part is attached to both ends from above. It is secured by a wire rod.

In this way, although the means for fixing vinyl sheets has become quick and reliable, the problem of removing condensed water inside arch-shaped greenhouses has not yet been solved. It is in.

In conventional arch-shaped greenhouses, a large number of arch-shaped structural members are arranged side by side, and the present applicant has proposed a method according to Utility Application No. 84721/1983, in which the dovetail-shaped support frame is used as a horizontal member for the arch-shaped structural members. The frame of the house was formed by fixing the house using fasteners proposed by the company, which was then covered with a vinyl sheet, and this was secured to a dovetail support frame using corrugated wire rods.

[Problem that the invention attempts to solve]

However, in the above-mentioned arch-shaped greenhouse, several dovetail-shaped support frames are installed horizontally around the outer periphery of the arch-shaped structural member, so that condensation water generated especially near the house ceiling on the upper support frame is There was a problem in that the water collided with the water as it flowed down and dripped onto the plants being cultivated, causing diseases such as root rot in the plants.

Therefore, a dovetail support frame shown in FIGS. 8 and 9, in which a groove for receiving condensed water is integrally formed, has come to be used. This is a conventional dovetail support frame 1 with one upper edge 2 extended and a condensation water receiving groove 3 integrally formed therein.

Further, in the system proposed in Japanese Utility Model Application Publication No. 56-3762, the gutter portion is formed separately from the sheet holding frame and is attached to the sheet holding frame.

However, in all of the conventional products mentioned above, one upper edge of the support frame is used as a drainage part, so when the vinyl sheet is blown by the wind, condensed water does not enter the condensation receiving groove but flows into the support frame. There were flaws.

Furthermore, there was a risk that the water flowing into the support frame would damage the sheets within the frame, and that the damage would eventually spread to the entire house.

Furthermore, if the support frame has a complicated shape as shown in Japanese Utility Model Application Publication No. 56-111652, special fixing metal fittings are required to attach it to the arch-shaped structural member, which reduces installation workability. There was a problem.

The present invention was devised in view of the above circumstances, and is a condensation water receiving member for a vinyl greenhouse that has a simple structure, is extremely easy to install, has good workability, and can reliably drain condensation water. is intended to provide.

[Means for solving problems]

In order to achieve the above object, the present invention has a folded part of the upper edge of the dovetail-shaped support frame for fixing the sheet of a greenhouse with a circular cross section, and a hard plastic dew condensation plate that is removably fitted into this folded part. In the water receiving member, an arc-shaped hook portion that can be fitted into a folded portion having a circular cross section formed on the upper edge of the dovetail support frame is provided at one end of the receiving member main body, and the hook portion and A side wall is formed by bending the other end of the upper surface extending at regular intervals downward, and a small protrusion protruding upward is provided on the ridgeline of the bent portion, and a lower part of the side wall is extended. It is characterized by forming a drainage groove portion for receiving dew condensation water.

[Effect]

Next, to explain the operation of the present invention, when constructing an arch-shaped greenhouse, a large number of arch-shaped structural members are arranged in parallel, and a horizontal pipe member is fixed to the top of each of the members. A dovetail support frame is fixed to the left and right shoulders of each of the arch-shaped structural members in parallel with the structure, and the drain groove part of the condensation water receiving member according to the present invention is positioned upward in the circular folded part of the upper edge of the support frame. and then fit it in place to complete the framework. Next, a vinyl sheet is covered from above the frame assembled in this way, the sheet is pushed into the dovetail groove of the dovetail support frame, and synthetic resin protectors with square grips are attached to both ends from above. It is secured by the attached corrugated wire.

When the vinyl sheet is stretched over the frame of the greenhouse in this way, the small protrusions protruding on the ridgeline of the side wall of the receiving member come into contact with the vinyl sheet, so condensation that occurs near the ceiling of the greenhouse When water flows down along the vinyl, the small ridges allow it to flow into the drain from the side wall and be reliably discharged, preventing it from dripping onto the cultivated plants in the greenhouse.

〔Example〕

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