Description

Prefabricated Panel for Greenhouse {Panel for prefab green-house}

The present invention relates to a prefabricated panel for a greenhouse, and more particularly, to provide a heat insulating performance by providing a fixed panel for simplifying installation and maintenance while having a double cover covering the panel assembled to the ceiling and the side wall of the greenhouse. The present invention relates to a prefabricated panel for greenhouses, which increases the opening ratio by increasing the opening ratio by increasing the aperture ratio by increasing the assembly rate and improving the assemblability, and the folding panel is located at an alternate position with the fixed panel.

In general, in order to intensively produce crops such as vegetables, flowers or fruit trees, greenhouses such as large greenhouses or glass greenhouses are installed and operated. However, crops such as vegetables and flowers require proper temperature and mining due to their growth characteristics. Therefore, ventilation for maintaining proper indoor temperature while ensuring proper mining in the installation operation of a greenhouse is the best. It is important. For example, shading to maintain the proper temperature in the room during a high temperature period will result in poor light mining and adversely affect the growth of crops. On the contrary, in order to ensure sufficient light, it will be difficult to maintain the proper temperature in the room, which will also affect crop growth. . Therefore, the method of providing the window to a greenhouse, ventilating a greenhouse as needed, ensuring the light required for the growth of a crop, and maintaining the temperature of the room is common.

However, most of the windows in a conventional greenhouse adopt a typical hinge method in which the other end is rotated and opened about one end thereof. Therefore, the opening ratio of the windows in the structural characteristics (for the support of the greenhouse by the wind when the windows are opened) is different. Since it is difficult to exceed 12-20% of the total surface area, it is impossible to maintain the required room temperature only by windows. In other words, the proper temperature required for the growth conditions of the crop is slightly different depending on the type of crop to be grown, but about 25 ~ 30 ℃ is appropriate, the temperature of the greenhouse at the high temperature is about 70 ~ 80 ℃ when sealed, Even if the windows are completely opened, the area is too narrow and the flow of the internal and external air is not made smoothly due to the structure of the windows, so it reaches about 40 to 50 ° C.

Accordingly, in the past, the indoor temperature of the greenhouse is forcibly lowered by using spraying water, a fan, or an air conditioner during a high temperature period, which requires a huge cost, which is a great economic burden for farmers, but it is difficult to be effective in a large greenhouse. There was.

In addition, in order to reduce heat loss to the outside during the low temperature period, the greenhouses are constructed by double or triple installation of vinyl, etc. The installation and maintenance of the greenhouse is quite complicated, and enormous costs are required for crop cultivation. This will further stimulate excessive temperature rise.

On the other hand, the above problems appear the same in other structures that require a large amount of indoor ventilation, such as factories or various barns.

The present invention has been made in view of the above-described conventional problems, and has an object to provide a prefabricated panel for a greenhouse that can easily perform the installation and maintenance of the greenhouse while having excellent heat insulating performance.

Another object of the present invention is to increase the opening ratio significantly while being able to withstand the wind sufficiently even when opening the window of the greenhouse, so that the room temperature is maintained appropriately to the growth conditions such as crops or livestock raising without a separate cooling means in the high temperature period. It is to provide a prefabricated greenhouse panel that can be naturally ventilated.

In order to achieve the above objects, the cooking panel for a greenhouse according to the present invention has a plurality of coupling slits on the inner circumferential surface, an inner frame having a fixed slit on the outer circumferential surface, and a space portion in the center. ); A plurality of cross bars arranged in a lattice shape in a space portion of the inner frame and having both ends fitted into and fixed to the coupling slit; Covers fixed to both sides of the inner frame to seal the space; And an outer frame coupled to an outer surface of the inner frame to surround the edge of the cover by providing a coupling channel on the inner circumferential surface thereof.

According to one preferred feature of the prefabricated panel for a greenhouse of the present invention, the cover is made of a rigid or soft transparent sheet having a tubular shape, and an edge portion thereof is fitted into a fixed slit by a wedge bar.

According to another preferred feature of the prefabricated panel for a greenhouse of the present invention, the cover is made of a glass plate, and its edge is interposed between the inner frame and the outer frame and then fixed by silicon caulking.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

First, the prefabricated panel 1 for greenhouses according to the present invention is divided into a fixed panel 10 and a flexing panel 60, except that the flexing panel 60 is flexed, and both have substantially the same configuration. For the basic configuration of the fixed panel 10 will be described as an example in order to avoid redundant description.

1 to 4, the fixed panel 10 is disposed in a grid shape in the inner frame 20 having a rectangular frame shape having a space portion 25 at the center, and the space portion 25 of the inner frame 20. The inner frame (1) is fixed to both side surfaces of the plurality of crossbars (30) and the inner frame (20) to enclose an edge of the cover (40) and the cover (40) to form an air layer by sealing the space (25). The outer frame 50 is coupled to the outer surface of 20).

The inner frame 20 is constructed by assembling or welding the pieces of the upper, lower, left and right four bars made of hollow rectangular bars. In each bar, the hollow part 21 is divided into the inner and outer hollow parts 22 and 23 by the baffle 24 arrange | positioned in the longitudinal direction. A plurality of coupling slits 26 for coupling the crossbars 30 are formed on the inner surface of the inner hollow part 22 at regular intervals, and fixed slits for fixing the cover 40 on the outer surface of the outer hollow part 23. (27) is formed in the longitudinal direction. The coupling slit 26 is a continuous first slit 26a formed along the longitudinal direction of each bar and a second slit 26b formed to be orthogonal to and spaced along the first slit 26a. This is because the crossbar 30 is formed crosswise (+) as described below. Therefore, the shape of the coupling slit 26 may be appropriately changed according to the shape of the crossbar 30.

On the other hand, the fixed slit 27 is for fixing the edge portion of the cover 40 by the wedge bar 43 when the cover 40 is made of a soft material, such as vinyl sheet 41, At its inner edge, elastic pieces 28 are formed to protrude in contact with the contact surface of the wedge bar 43.

The crossbar 30 is intended to stably maintain the shape of the fixed panel 10 and to support the cover 40. The crossbar 30 may have any shape as long as it can exert a desired function, but preferably has a cross-shaped cross section. Have A plurality of such crossbars 30 are provided to be combined to be orthogonal to each other to form a lattice in the space 25 of the inner frame 20. Thus, two adjacent ribs 31 and 32 are formed longer than the other two ribs 33 and 34 by their thickness, and any one of the ribs 31 and two adjacent ones formed relatively long is formed. Ribs 32, 34 are formed with a plurality of assembly slits 35, 36, 37 at regular intervals for coupling with other cross bars 30 that are perpendicular to each other. This is because the crossbars 30 are formed crosswise to match the upper and lower ends of each crossbar 30 when assembled. Accordingly, the first slit 26a of the coupling slit 26 of the inner frame 20 has a width corresponding to at least twice the thickness of the ribs 31 to 34 of the crossbar 30.

In this case, only one rib 31 of the crossbar 30 may be formed relatively long, but the inner frame 20 is increased in length to fit the coupling slit 26 of the inner frame 20 to realize a more stable assembly state. The rib 32 fitted to the engaging slit 26 of 20 is formed to be long together.

The cover 40 may be used in various ways. In the case of a greenhouse, since appropriate lighting is required, the cover 40 is made of a soft transparent sheet such as a vinyl sheet 41 or a transparent body such as a glass plate 42. For example, when the vinyl sheet 41 is formed, the edge portion of the vinyl sheet 41 is fitted into the fixing slit 27 of the inner frame 20 by the wedge bar 43 to fix the air layer to the space 25 of the inner frame 20. Bar is formed, it is preferable that the vinyl sheet 41 is configured in a cylindrical shape so that the inner frame 20 can be inserted for convenience of production.

Like the inner frame 20, the outer frame 50 is formed by assembling the pieces of four bars up, down, left, and right in a rectangular frame shape, and each bar has a substantially c-shaped cross section opened inward. Accordingly, a continuous coupling channel 51 for inserting the inner frame 20 is formed on the inner circumference of the outer frame 50. Preferably, the inlet of the coupling channel 51, that is, the inner end of the outer frame 50 is formed so that the engaging jaw 52 elastically caught on the inner end of the inner frame 20 to face each other. In addition, rainwater for preventing rainwater from entering the interior of the greenhouse at both edges of the outer surface of the outer frame 50, that is, at both edges in a direction in which the plurality of panels 1 are continuously disposed during the construction of the greenhouse. Inflow preventing jaws 53 are formed.

Such inner and outer frames 20 and 50 and the crossbar 30 are preferably made of a hard metal such as aluminum or a high strength synthetic resin material.

Next, the manufacturing method of the prefabricated greenhouse panel according to the present invention having such a configuration will be described.

First, a plurality of crossbars 30 are assembled to each assembly slit 35 to 37 to form a lattice, and both ends of each crossbar 30 are corresponding coupling slits 26 of the inner frame 20. The upper, lower, left and right bars are combined to be fitted into the fields, and adjacent ends of the bars are assembled to each other. Next, the cylindrical vinyl sheet 41 is put on the inner frame 20 to which the crossbar 30 is assembled, and the wedge bar 43 is fitted to the fixing slit 27 on both sides thereof. Then, the vinyl sheet 41 is fixed to the inner frame 20 while being tensioned by the wedge bars 43, wherein the elastic piece 28 of the inner frame 20 is elastically deformed by the wedge bar 43. As a result, the vinyl sheet 41 is fixed very firmly. Next, after folding the upper and lower ends of the vinyl sheet 41 with respect to the inner frame 20, and then inserting the upper and lower wedge bars 43 into the fixing slits 27, the upper and lower ends of the vinyl sheet 41 are respectively. Is sucked into the fixing slit 27 of the inner frame 20 along the wedge bar 43 is fixed to form an air layer in the space portion 25 of the inner frame 20. In this state, the upper, lower, left and right bars of the outer frame 50 are respectively coupled to the outer surface of the inner frame 20. Then, the latching jaw 52 formed at the inner end of each bar of the outer frame 50 is elastically latched and fixed to the inner end of the inner frame 20, and is then manufactured by fixing adjacent ends of the bars to each other. .

5 shows a state in which the glass plate 42 is adopted as the cover 40 instead of the vinyl sheet 41 described above. In this case, the glass plate 42 is placed on the inner and outer surfaces of the inner frame 20 to which the crossbar 30 is assembled, and the upper, lower, left, and right bars of the outer frame 50 are combined to surround the edges of the two glass plates 42. After fixing to each other, the inner end of the outer frame 50 and the two glass plates 42 are produced by fixing each with silicon caulking. Therefore, when the glass plate 42 is adopted as the cover 40, the wedge bar 43 is unnecessary.

On the other hand, Figure 6 to 8 is shown the flexural panel 60 of the prefabricated panel for greenhouses according to the present invention, which is the same as the basic configuration of the fixed panel 10 and the inner frame, crossbar cover and outer frame, etc. Therefore, the same reference numerals are written in corresponding parts, and thus detailed description thereof will be omitted.

As shown, the flexural panel 60 is a panel body separated from each other consists of two partitions of the upper panel 61 and the lower panel 62, the upper and lower panels 61, 62 are hinges 63 It is comprised by being connected so that each other can be bent by folding means, such as these. Cover flanges 65 and 66 which cover the edges of the adjacent fixing panels 10 on both outer surfaces of the upper and lower panels 61 and 62, that is, both sides of the arrangement direction during the construction of the greenhouse. Are each provided. The cover flange 64 is for preventing rainwater from flowing into the greenhouse through the gap between the adjacent fixed panel and the flexural panel 10, 60, and at least the rainwater inflow prevention step of the fixed panel 10. It is formed so as to cover 53 sufficiently.

In addition, as shown in FIG. 8, the bottom surface of each cover flange 65 and 66 may be in close contact with the outer surface of the adjacent fixing panel 10 to maintain airtightness. It is preferable that the packing 67, such as a rubber material, is provided together.

In addition, the flexural panel 60, which is separated from each other, the upper and lower panels 61 and 62 are integrally connected by the hinge 63, so it is necessary to surely prevent the gap therebetween. To this end, as shown in FIG. 7, a second cover flange 68 is provided at the lower end of the outer side of the upper panel 61 to cover the upper end of the outer side of the lower panel 62. A second rainwater inflow prevention jaw 69 is positioned at an inner side of the second cover flange 68.

The prefabricated panels 10 and 60 for greenhouses according to the present invention have an air layer between the inner and outer covers 40, and thus, the thermal insulation performance is significantly improved as compared with the conventional greenhouse simply surrounded by several layers of vinyl. The installation and maintenance by the assembly structure as described above becomes very simple.

On the other hand, Figure 9 is a schematic perspective view of a greenhouse constructed using the prefabricated panels according to the present invention as described above, Figure 10 is a cross-sectional view of FIG. As can be seen in these figures, the greenhouse is constructed by alternately arranging a plurality of fixed panels 10 and flexural panels 60 on the frame 110, which configuration only applies to the ceiling of the greenhouse 100. Alternatively, it is possible to employ both ceilings and side walls as necessary. Each fixed panel 10 is fastened and fixed to the frame 110 through a C-shaped steel 130, for example, and the flexural panels 60 are movable supporting means (described below) between the respective fixed panels 10 ( 70 is installed to be stretchable with respect to the frame 110.

In the greenhouse having such a configuration, the opening of the window is divided into two parts by the upper panel 61 of the flexing panel 60, the upper part is exposed to the front side, and the lower part is exposed to the side by the flexing panel 60. In addition, the flow of internal and external air is very smoothly and quickly. That is, as shown in FIG. 9, the high temperature bet is quickly exited to the outside through the upper front exposed portion and at the same time, the low temperature outside air is rapidly introduced into the inside of the greenhouse 100 through the lower side exposed portion. The flow is made at the same time almost all parts of the greenhouse 100 is to maximize the ventilation rate. Therefore, it is possible to maintain the internal temperature of the greenhouse 100 at a temperature suitable for the growth of the crops without a separate cooling means at a high temperature, while also ensuring proper lighting.

On the other hand, in the above-described and illustrated embodiments, only the example of applying the present invention to a greenhouse, but this is merely for the purpose of illustration, the present invention is not limited thereto, for example, such as barn, barn, barn and pig house Of course, it can be applied to similar structures that require indoor ventilation, such as barns, factories, and warehouses.

As described above, according to the present invention, as the greenhouse is assembled into a unit, the production is simple, the transportation and installation is easy, and even if a part is damaged, only the corresponding panel can be simply replaced, thereby making maintenance extremely simple. In addition, since the unit panel constituting the greenhouse has an air layer between its inner and outer covers and has excellent heat insulating performance, a prefabricated panel for greenhouses is provided which is very advantageous for maintaining an appropriate indoor temperature of the greenhouse. It is able to withstand strong winds at the time of opening, and its opening ratio is greatly increased, and the inflow and outflow of internal and external air through windows and windows is made very smoothly and quickly. The temperature can be maintained to be suitable for the growing conditions of the crop.

The present invention can also greatly improve the ventilation, heat insulation and robustness of the greenhouse, as well as having a great effect on reducing the cost of crop cultivation. In addition, there is also an excellent effect that exerts excellent ventilation even when constructing a structure such as a barn or a factory using a general prefabricated panel.
