Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a greenhouse with an openable canopy using a composite transparent panel made of plastic as a covering material.

Some conventional greenhouses use glass panels as covering materials, for example. Glass is often used as a covering material because of its good translucency and beautiful appearance.However, due to its brittleness, glass is vulnerable to external pressure such as wind pressure and snow load in snowy areas and is easily broken. ,
A single board that is too wide cannot be used, and a board that is at most several tens of centimeters square is used. For this reason, we produced
The problem was that repairs were time-consuming and costly. In addition, in addition to being easily broken, it is difficult to construct a greenhouse with a canopy that can be opened and closed because the material is relatively heavy, and even if it can be constructed, it is difficult to construct a canopy with a relatively canine shape. For this reason, there was a problem that ventilation by opening the canopy and the intake of ultraviolet rays etc. could not be achieved sufficiently. Furthermore, glass veneers have a problem in that their heat transmittance is not sufficiently low to create a greenhouse with good heat retention.

The present invention aims to solve these various conventional problems.

The present invention will be explained below based on the drawings. Figures 1 to 7
The figure shows an embodiment of the present invention.

First, the covering material will be explained with reference to Figures 1 and 2.
Two plastic transparent plates (1) (1) are opposed to each other with an interval of about 10m+n, for example, and a honeycomb-shaped intermediate core material (2) is placed between these two transparent plates (1) (1).
is mediated. The intermediate core material (2) is made of the same transparent plastic as the transparent plate (1), and its hexagonal cell size (2a) is approximately 12n+m. The transparent plate <1) (1) and the intermediate core material (2) are adhered with a transparent adhesive to form a composite transparent panel (3) as a covering material.

The impact resistance or rigidity of the covering material is improved by the interposition of such an intermediate core material (2), and furthermore, the insulation property, that is, the heat retention property is improved by the interposition of small independent spaces made of nicum. ing. The edge of the intermediate core material (2) is crushed under heating to form a strong plate part (3a) as shown in FIG. It is used as a mounting part during installation and is fixed to a steel material (4) such as a frame member by screws or the like.

The covering material consisting of such a composite transparent panel (3) is then assembled to the frame to construct a domed greenhouse with a retractable canopy as shown in Figures 3 and 4. (5)
(6) is a canopy (skylight), (7) is an entrance/exit door, and canopies (5) and (6) are arranged on both sides of the breast (8), respectively. The bottom chamber width (bottom width in Figure 4) of greenhouse body A is approximately 3 m, and the chamber length (depth length)
is approximately 4m in size. As described above, the composite transparent panel (3) serving as the covering material has high rigidity and is lightweight, so relatively large panels each having a size of about 1 x 2 m are used. Each of the canopies (5) and (6) is large in width and spans the entire length of the room. (9)
α is a handle, which is used when opening and closing the canopy (5) (6). Further, the side walls of the canopy (5) (6) and the greenhouse main body A have a cylindrical curved surface with a radius of curvature of about 2.3 m to form a round roof type. By forming such a curved surface, the rigidity of the covering material against external pressure is further increased.

Incidentally, the composite transparent panel (3) can be easily formed into a curved surface with the above-mentioned radius of curvature by heat forming.

Next, the opening/closing mechanism of the canopy (5) (61) will be explained with reference to FIGS. A roller (14) (141) is attached to the part of this panel support frame a''IJ. Guide rails (15a) (i5b) made of angle iron are arranged on the greenhouse body A side.The guide rails have a guide rail part (15a) corresponding to the closed position (upper part of the roof) of the canopy (5). , a step portion (15c) is formed at the intermediate portion between the guide rail portion Qsb) corresponding to the open state, and the guide rail portion (15b) on the open state side is configured to be one step higher.
c) is the canopy (5) in the closed state as shown in Figure 7;
It is considered as a locking part. In addition, an eave-like overhang (5a) is provided at the lower edge of the canopy (5), and when the canopy (5) is closed, the overhang (5a) is attached to the side wall (
Airtightness is maintained against the outer surface (external surface). In FIG. 4, αe is a weight for balancing the canopy (5), and is connected to the upper end of the canopy (5) by a wire αυ via a pulley (zla) (21b). Wholesale is canopy (6)
With the weight for the wire α value, the pulley (ztc)
(21d) is connected to the upper end of the canopy (6).

Next, the opening/closing operation and function of the canopy will be explained. First, the case of opening operation will be described. Lift the handle (9) from the closed state as shown in Figure 4 and move the lower roller (14) α4 to the step part (15).
c) and lower the guide rail part (15b).
). Then, the handle (9) is pulled downward against the weight of the weight aQ to open the canopy (5).

Although the canopy (5) is formed to be as large as half the size of the roof, it is relatively lightweight, so it can be easily opened by such an operation. The operation for opening the other canopy (6) is also similar to the above. When the canopies (5) and (6) are opened, about half of the roof of the greenhouse body A is opened, allowing for sufficient ventilation and sufficient ultraviolet rays. If the state is
It is also possible to draw sufficient natural rainwater into the greenhouse.

When closing from the open state, perform the reverse operation to the above.

In the closed state, the canopy (5) (f6) is ensured to be in the closed state due to the locking action of the stepped portion (15c) and the action of the wave (f9 (17)). Also, the overhanging part (5a) (6
Airtightness or heat retention is achieved by the contact action in a).

FIG. 8 shows another embodiment of the invention. In FIG. 8, members or parts that are the same as or equivalent to those in FIGS. 1 to 7 are designated by the same reference numerals and redundant explanations will be omitted. This embodiment is a double-roof type greenhouse in which side windows (c) are also provided in the side walls of the greenhouse body A. The width of the side window (to) is almost the same as the total length of the room, and it is formed large like the canopy (5). The opening/closing mechanism is a sliding door type that can be opened and closed in the vertical direction.

According to the present invention, as described in detail above, two
A composite transparent panel with a plastic honeycomb-shaped intermediate core material interposed between two plastic plates is used, and at least the canopy can be opened and closed freely, making the covering material highly impact resistant and rigid. This makes it possible to make the greenhouse extremely strong against external pressures such as wind pressure and snow loads. Further, since the composite transparent panel has high rigidity and is heavy, the size of one sheet of the covering material can be made considerably large. Therefore, the number of man-hours required during manufacturing can be reduced, reducing manufacturing costs, and repairing can also be facilitated, reducing repair costs and reducing overall costs. Furthermore, the area of the canopy can be made quite large, so 1. .

When this is opened, the ventilation capacity is sufficiently large, and ultraviolet rays can be sufficiently taken in. Furthermore, when it is opened during rain, natural rainwater can be sufficiently taken into the greenhouse. Furthermore, the sheathing material has a large number of small independent spaces due to the presence of the nicum-shaped intermediate core material, so the heat transmission coefficient is about 2 when compared to that of a single glass plate.
It has a sufficiently small value of about 1/2 that of the average temperature, and various effects can be obtained by providing a greenhouse with extremely good heat retention.

In addition to the above-mentioned common effects, each of the embodiments also provides the following effects.

According to an embodiment in which the greenhouse is of a round roof type and the covering material has a curved surface, the tonality of the covering material is further increased and the greenhouse can be made even stronger against external pressure. In addition, a step is formed in the middle between the guide rail section corresponding to the closed position of the canopy and the guide rail section corresponding to the open state, so that the guide rail section corresponding to the open state is configured one step higher. is the locking part of the canopy in the closed state, and an eave-like overhang is provided at the lower edge of the canopy, and when the canopy is in the closed state, the overhang is in contact with the outer surface of the greenhouse body According to this embodiment, it is possible to improve heat retention when the fire lid is closed.
