Example Embodiment

[0031] (Embodiment 1).

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

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

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

Example Embodiment

[0046] (Embodiment 2)

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

[0048] in Figure 12A , 12B Two examples of the arrangement (position and unfolding direction in the stored state) of the shading and thermal insulation curtains are shown in. Figure 12A It is the case where the direction of the ridgeline of the roof of the greenhouse is at right angles to the direction in which the curtain expands. 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 unfolding direction of the curtain. The two are distinguished and used by the location of the greenhouse or the spacing of the columns, and the structure of the curtain driving device.

[0049] Here, the present invention is Figure 12A That is, the storage position of the curtain is the joint part of the roof on the north side, and the unfolding direction is the situation that it unfolds to the south. F...

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...
