DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film fixing device for assembling a greenhouse in which the roof surface and the wall surface of the greenhouse have a double structure.

[0002]

2. Description of the Related Art Generally, a greenhouse for cultivating a house is constructed by assembling a house-shaped frame with a steel frame, attaching a film fixing device to a tree-like shape at an appropriate interval, and covering this with a transparent film.

[0003] However, in a greenhouse in a cold region, the temperature of the greenhouse drops at night, so that there are places where heating is performed only at night. In this case, when the humid air heated by the heating rises to the ceiling side and the outside air cools in the morning, the humid air in contact with the film on the ceiling side is cooled, and water droplets condense on the inner surface of the film. Like frosted glass,
There was a problem that the sunlight did not sufficiently irradiate the inside of the greenhouse in the morning until the water droplets evaporated. In addition, water droplets condensed on the inner surface of the film may fall on crops such as flowers and vegetables grown in the greenhouse and damage the crops, and the attached water may cause germs to propagate and cause disease and insect damage. Was.

[0004] For this reason, a curtain is installed in the middle of the greenhouse so as to be openable and closable so as to cover the upper part of the crop, and the curtain is closed at night to prevent the air heated by heating from escaping to the ceiling to save energy. It has also been practiced to reduce the generation of water droplets on the inner surface of the film. However, the structure equipped with this curtain is expensive, and it is not possible to reliably prevent water droplets from being generated on the ceiling surface, and it is possible to prevent falling water droplets from being caught by the curtain and directly hitting the crops. There is a problem that the curtain is broken due to the weight of the water because the water gathers and accumulates in a low place of the curtain.

[0005] For this reason, the roof surface and the wall surface of the greenhouse have a double structure, and a heat insulating space portion is formed between the outer wall film and the inner wall film to enhance the heat insulating effect of the greenhouse and to save energy. Double-structure greenhouses, which prevent dew condensation in the forest and protect crops, have become widespread.

Hitherto, various structures have been developed as an assembling film fixture for use in assembling this double-structure greenhouse. For example, as shown in FIG. 3, a lower fixing member 4 in which screw pockets 3, 3 each having a V-shaped cross section are provided at both ends of a mounting plate 2 connected to a frame 1 of a greenhouse.
And a film presser 5 overlapping the lower fixing member 4.
An upper fixing member 7 in which a support rail 6 having a concave section is formed at the tip of the support 6 and one side wall of which is a screw pocket 3 having a V-shaped cross section;
The upper fixing member 7 includes a film holding plate 8 which overlaps the screw pocket 3.

The film fixing device for assembling a greenhouse having this structure is as follows.
The lower fixing member 4 is disposed on the frame 1 at right angles to the frame 1, and the mounting plate 2 is fixed to the frame 1 with screws 9. Next, the inner wall film 11 is provided so as to cover the lower fixing member 4, and the film holding portion 5 of the upper fixing member 7 is overlapped from above, and the screw 9 is joined to the screw pocket 3 of the lower fixing member 4 from above. Then, the inner wall film 11 is fixed.

Next, an outer film 12 is provided so as to cover the upper fixing member 7, and the film holding plate 8 is stacked from above the screw pocket 3 of the upper fixing member 7, and the screw is screwed into the screw pocket 3 from above. 9 and the outer wall film 12 was fixed to assemble a greenhouse having a double structure.

In this conventional structure, when the internal pressure of the greenhouse increases, the inner wall film 11 is lifted, and the lower fixing member 4 is lifted.
The film holding portion 5 of the upper fixing member 7 holding the inner wall film 11 is lifted from above. Since the screw pockets 3, 3 of the lower fixing member 4 are formed upward, the screws 9 are lifted by the inner wall film 11, and
There is a problem that the film 11 cannot be supported because it comes out of the screw pocket 3.

[0010] Further, the film holding portion 5 is provided with a screw pocket 3,
At the time of fixing to 3, the screwdriver for mounting the screw 9 is close to the upper receiving rail 10, so that there is a problem that the assembling workability is poor. Further, the film holding portion 5 of the upper fixing member 7 which is superimposed on the screw pockets 3 of the lower fixing member 4 is
Since it is formed in a flat plate shape, the lateral width is long, and there is also a problem that the amount of sunlight entering the greenhouse is reduced.

[0011]

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned problems, can reliably prevent the upper fixing member from coming off, has excellent assembling workability, and has a large number of sunlight rays entering the greenhouse. A film fixing device for assembling a structural greenhouse is provided.
