Problems solved by technology

[0002] Although plastic greenhouses for agriculture refer to spreading a transparent plastic film (vinyl film) on a frame made of metal, etc., trapping the sun's heat to keep the inside of the greenhouse warm, to promote the growth of crops, or to stagger the harvesting period, thus Achieving a high price transaction, but in the case of only one piece of film, due to the heat conduction of the film, the temperature inside the greenhouse at night is reduced to almost the same as the outside temperature, and these goals cannot be fully achieved

Embodiment approach 1

[0032] figure 1 An agricultural greenhouse of the type called a flat-sheet greenhouse is shown in which a film is spread flatly on a metal frame. figure 2 is a perspective view of panel members arranged side by side on the roof surface of the agricultural greenhouse, image 3 It is a side view of the main part of this panel part.

[0033] Such as figure 1 As shown, a plurality of roof panel members 1 are arranged side by side on the roof surface of an agricultural greenhouse (hereinafter referred to as a greenhouse). The roof panel part 1 is supported by the agricultural greenhouse structure part 2 .

[0034] Such as figure 2 As shown, the roof panel part 1 has a rectangular frame part 3 forming an outer frame. Inside the frame member 3, wooden strips are provided as reinforcement members as required. On both sides of the frame part 3, unfold like image 3 Light-diffusing light-transmitting films 4, 5 are shown.

Embodiment approach 2

[0047] Next, an example in which a curtain for shading or heat retention is combined is shown.

[0048] exist Figure 12A , 12B Two examples of the arrangement (the position in the stored state and the unfolding direction) of the light-shielding and heat-retaining curtains are shown in . Figure 12A It is the case where the ridgeline direction of the roof of the greenhouse is at right angles to the unfolding direction of the curtain, Figure 12B This is the case where the direction of the ridge line of the roof of the greenhouse is in the same direction as the direction in which the curtain is deployed. These two are differentiated and used by the location of the greenhouse, the interval of the columns, the structure of the curtain driving device, and the like.

[0049] Here, the invention is Figure 12A In this case, the storage position of the curtain is the seam part of the roof on the north side, and the deployment direction is southward. Figure 13 A cross-sectional ...

Abstract

A building direction of a greenhouse with double-layer light-transmissive films is an east and west beam, and light incidence angle is smaller than that of a north and south beam, so Fresnel reflection ratio is reduced and light transmittance of the double-layer light-transmissive film as a whole can be improved. The greenhouse has double-layer light-transmissive film or double-layer light-transmissive plates which form an air heat insulated layer. In the light-transmissive film or the light-transmissive plate, the light-transmissive film or the light-transmissive plate of at least any one of the inner side surface of the greenhouse and the outer side surface of the greenhouse is a photo diffusion light-transmissive film (4,5) or a photo diffusion light-transmissive plate which make light diffused, construction is performed in an east and west beam manner that a ridge direction of a roof is roughly in east and west direction.

Description

technical field [0001] The invention relates to a double-layer light-transmitting film or a covering structure of a light-transmitting board for improving thermal insulation in agricultural plastic greenhouses. The so-called film or plate differs only in thickness and hardness, and does not differ in the function of blocking air and roughly transmitting light. In this specification, when the expression "film" is used, the so-called "plate" is also included. Case. Background technique [0002] Although plastic greenhouses for agriculture refer to spreading a transparent plastic film (vinyl film) on a frame made of metal, etc., trapping the sun's heat to keep the inside of the greenhouse warm, to promote the growth of crops, or to stagger the harvesting period, thus Realize high-priced transactions, but in the case of only one film, due to the heat conduction of the film, the temperature in the greenhouse at night is reduced to almost the same as the external temperature, and...
