Description

[Detailed Description of the Invention] This invention relates to a device mainly consisting of a waterproof sheet for the valleys of the house, which is completely covered in the valleys between the rows of a multi-building vinyl greenhouse for cultivation.

First, an example of the structure of this type of multi-building greenhouse will be explained with reference to FIGS. 1 and 2.

Figure 1 shows the appearance of two rows of houses in the row of houses covered with vinyl covers 1, but as shown in Figure 2, they are assembled in a semi-cylindrical shape to form the framework of each house. The resin roof pipes 2 are connected and supported between rows of houses as described below, and form valleys 3 of the houses.

In other words, on the ground directly below the center line of valley 3,
Supports 4 are erected at multiple locations, and each support 4
A beam 5 made of overlapping sleepers is vertically suspended on the top surface of a C-shaped steel frame, and the top surface of the beam 5 has a large number of joints with ears extending diagonally upward on both the left and right sides. A metal fitting 6 is fixed, and the side ends of each roof pipe 2 of an adjacent house are connected to the same joint metal fitting 6.
It is fixed and held on the back side of the ear piece.

By the way, the roof surface of the valley 3 is covered with a waterproof sheet that acts as a gutter to drain accumulated water to both the front and back sides of the house.
As shown in FIG.
The sheet 7 is placed over the roof pipes 2 and the roof pipes 5 and 5, and both side edges of the sheet 7 are secured to the hem of each roof pipe 2 by clips 8.

Here, as a characteristic of the house structure, during times of sunshine such as in summer, a phenomenon occurs in which the beams 5 receive direct heat from sunlight and are overheated to a high temperature. The tarpaulin sheet 7 had the drawback that thermal deterioration occurred due to heat transfer from the overheated slats 5, and as a result, the life of the tarpaulin sheet 7 was inevitably shortened.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a waterproof sheet device for a house trough that has a long service life.

As a means to achieve this purpose, the present invention provides a beam 5 that extends almost entirely through the lower part of the valley between the rows of a multi-building vinyl greenhouse for cultivation, and is built on top of a support 4 that is erected on the ground. The cross section is approximately U along the frame of the house, and extends completely along the upper surface of the beam 5.
In a waterproof sheet device for a house valley in which a shape is covered with a waterproof sheet 9, the waterproof sheet 9 is
The house trough is made of a long plastic sheet, and is characterized in that a plurality of rows of protrusions 9a extending in the longitudinal direction opposite to the upper surface of the beam 5 are integrally formed on the back surface of the sheet. In the tarpaulin equipment.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

As shown in FIGS. 4 and 5, the waterproof sheet 9 of the embodiment is made of a long elastic plastic sheet that covers the bottom of the roof pipe 2, and has double rows on the back side of the sheet. Convex strip 9 along the longitudinal direction of
The sheets a are thickly formed at approximately equal intervals, and are covered in the valleys 3 between the rows of houses, as in the case of the conventional waterproof sheet described above.

In the waterproof sheet 9 of the embodiment configured in this way, when the trough portion 3 is covered, the tip edges of the protrusions 9a on the back side of the sheet 9 only come into contact with the ridges 5 and the fittings 6. Most of the lower surface is in contact with the space such as the gap 10, so even if both members 5 and 6 become overheated, the waterproof sheet 9 will not reach a high temperature, meaning that the degree of thermal deterioration during use is extremely low. Very little. The material of the waterproof sheet 9 is the same as that of a normal agricultural plastic sheet, that is,
It is made of various thermoplastic plastics or thermoplastic elastomers such as polyethylene, polyvinyl chloride, and ethylene/vinyl acetate copolymers. Further, the thickness of the waterproof sheet 9 is preferably about 1 mm.

As described above, according to the waterproof sheet device for the valley of a house according to the present invention, the convex stripes along the longitudinal direction are integrally formed in double rows on the back surface of the waterproof sheet, and the convex stripes of the sheet are placed downward. Since it is made to extend along the top surface of the waterproof sheet 5, it is possible to create a gap between the sheet and the top surface of the house skeleton, and as a result, the sheet is prevented from becoming hot and the service life of the waterproof sheet is extended. It has a stretching effect.

In addition, since the double-row protruding stripes 9a are integrally formed to protrude from the back surface of the waterproof sheet 9,
This has the effect of making it easier to manufacture and handle.
