Description

Assembled greenhouse structure

Technical Field

The present invention relates to an assembled greenhouse structure, and more particularly, to an assembled greenhouse structure that can reduce damage and breakage by coping with strong and frequent wind or large snow accumulation in a process of forming a greenhouse for promoting cultivation of vegetables or flowers or for winter cultivation and cultivation of tropical plants.

Background

A general plastic greenhouse is a greenhouse structure covered with a plastic film for promoting growth of vegetables or growth of tropical plants, and is widely spread since application of the plastic film to agriculture, and is a popular gardening facility.

The plastic greenhouse is characterized in that the heat preservation capability is higher due to high air tightness, and a favorable environment is provided for the growth of crops due to higher light transmittance.

However, a plastic film used as a covering material for a vinyl house is easily torn by a constant pressure when blown by wind frequently and has a high strength, and is easily damaged or broken by branches, gravel, or the like caught by wind, and is easily damaged or broken by a load when the amount of snow is large.

Further, the plastic film is likely to be dirty, which may cause a decrease in light transmittance, and may be damaged or broken during cleaning or snow removal of the dirty plastic film.

One of the reasons for the short life of the vinyl house is that the temperature inside the vinyl house is maintained at about 50-80 ℃ in a sunny day, and on the contrary, the temperature drops rapidly at night, so that the vinyl house is damaged by heat and cold.

In particular, in the case of partial damage, the vinyl house is difficult to partially replace.

In the related art, in forming a ceiling structure, a small-sized plate material (referred to as "slate") formed by bending a plastic plate material in a wave pattern in one of a width direction and a longitudinal direction is arranged so that portions of edges thereof overlap each other, and is fixed to a support structure such as a frame.

When the corrugated plastic plate (referred to as a "slate plate" for convenience of description) is used instead of the plastic of the vinyl house, the plastic can be bent in a direction in which the corrugations are repeatedly present (referred to as a "width direction" for convenience of description), but it is difficult to bend in a direction perpendicular to the corrugated direction in a plane (referred to as a "length direction" for convenience of description).

Therefore, when the slate board is used for a greenhouse structure such as a vinyl house, the width direction of the slate board is aligned along the mold frame direction having a substantially arch shape in the framework structure, the longitudinal direction of the slate board is oriented in the direction of a support frame (substantially along the longitudinal direction of the vinyl house) capable of supporting the mold frames while maintaining the interval therebetween, and a part of the overlapping edge of the slate boards is fixed to each other by a common connector such as a rivet or a bolt.

However, the slate board has a high thermal expansion coefficient due to the characteristics of the synthetic resin material of the slate board, and does not have toughness as in plastic, and therefore, has a change in tension or shrinkage caused by a temperature difference between winter and summer.

The above-described change in the tension or contraction of the slate plates occurs substantially along the radial direction of the area, and therefore, the plurality of slate plates provide a force of pushing away or pulling each other with reference to the position where the fixation is achieved.

The force derived from this is confirmed by the following equation 1 and equation 2 based on the pythagorean theorem for obtaining the variable based on the thermal deviation in the longitudinal direction, and is raised from the support structure (the mold frame and the holder) or spread from each other with respect to the area range of the limited installation region.

Mathematical formula 1

b＝a+a(Tl-T0)Ct

d＝b-a＝a(Tl-T0)Ct

Length at time T0 (length at temperature T0)

Length at time T1 (length at temperature T1)

T1-T0 temperature difference (difference in temperature)

Ct-thermal expansion coefficient (thermal expansion coefficient) (70-105 cm/cm2 ppm/T)

d-length deformation based on thermal deviation

In The following description, The coefficient of thermal expansion (Ct) in equation 1 is represented by The coefficient of thermal expansion of 70 to 105cm/cm2 ppm/T of polypropylene (PP) which is generally used (see: J.F.Shackelford and W.Alexander, The CRC Materials Science and Engineering Handbook, 3rd ed., CRC Press, Boca Raton, FL, 2001).

The coefficient of thermal expansion (Ct) is exemplified by polypropylene, but it is estimated that polyethylene or other synthetic resin materials having higher values have problems in terms of changes in elongation and contraction and the deformation relationship caused by the changes.

Mathematical formula 2

b²＝a²+c²

a is a distance from the center to the edge of the plate before deformation (length at T0)

b is the distance from the center to the edge of the deformed rock plate (length at T1)

c-spacing of the support structure from tilting due to tensile deformation of the slate board

d is the length of deformation due to thermal deviation of the slate plate

In the following, the deformation and the problem caused by the thermal deviation of the slate plate are examined by substituting the exemplified numerical values into

equations

1 and 2.

Note that the deformation in the width direction of the slate board (the direction in which the wave is bent) due to thermal deviation can be replaced by a change in the degree of bending, and the interval between the fixed positions is not imaged, and the

above equations

1 and 2 are described only by replacing the lengthwise direction of the slate board (the lengthwise direction of the valleys).

Therefore, when the temperature in winter reaches-20 ℃ (T0), the length (fixed interval between both sides in the longitudinal direction) a of the slate board is 1m, when the temperature in summer reaches (considering the greenhouse structure) 60 ℃ (T1), the length deformation d of the slate board stretched by the temperature difference (80 ℃) on "a" is 5.6-8.4 mm, and when the length deformation of the adjacent connected slate boards is inclined to one side, the deformation is doubled, namely 11.2-16.8 mm.

In particular, in the greenhouse structure, the length in the longitudinal direction is greater than the length in the width direction, and when a plurality of slate boards are connected, the amount of deformation in the length increases with the number of connected slate boards, and the parts connected to each other or the intermediate parts are forced to be pushed away from each other by the support structure, and the parts connected to each other or the intermediate parts are raised from the support structure.

On the contrary, when the temperature changes from summer to winter, shrinkage corresponding to the deformation occurs along the longitudinal direction of the support structure, and the interconnected portions are pulled apart and broken, which causes a problem.

This eventually leads to the deterioration of the airtightness of the greenhouse structure, and thus there are many difficulties in applying the synthetic resin material sheet to the greenhouse structure.

In addition, on the surface of the cover plate, at least at the edge portion in the width direction overlapping with the pad plate, a recessed portion is formed in the upper surface of each portion at intervals along the longitudinal direction thereof, the recessed portion being recessed or protruded while maintaining the thickness, and on the edge in the width direction of the pad plate or the cover plate, a locking portion is formed to lock the edge in the width direction in accordance with the movement in the width direction of the recessed portion.

Further, it is preferable that a sealing member formed of one of rubber and silicone is further provided at the edge portions in the width direction of the pad plate and the cover plate.

On the other hand, elastic members are provided at both ends of the pad plate, the cover plate, and the cover plate in the longitudinal direction, the elastic members being fixed at one end and fixed at the other end to the support structure or the floor so that the pad plate, the cover plate, and the cover plate are elastically stretched in the longitudinal direction.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 6, the assembled greenhouse structure 10 of the present invention, like a general vinyl house, includes:

support structures

12a and 12b formed by connecting a plurality of mold frames 12a and holders 12b so as to correspond to a cultivated land S having a set width W and length L; and a covering material for covering the periphery of the

support structures

12a, 12 b.

First, the covering material of the present invention includes the backing plate 14, and the backing plate 14 is provided as a band-shaped plate material having a predetermined width and length by being supported by the mold frame 12a and/or the bracket.

That is, as shown in fig. 1, the backing plate 14 may be a structure fixed to the frame 12b in a shape of being aligned with the frame 12a of the

support structures

12a and 12b, or may be a structure arranged in parallel with the frame 12b and fixed to the frame 12a, or may be a structure provided in a shape corresponding to each of the frame 12a and the frame 12 b.

However, when the backing plate 14 is formed as a structure which is fixed to the holder 12b in parallel with the mold frame 12a, it may be formed as a structure which replaces the mold frame 12a, and may be provided so as to be continuously arranged at a predetermined interval along the longitudinal direction of the holder 12b on the outer side of the holder 12 b.

Further, it is preferable that, among the intervals of the plurality of tie plates 14, the interval between the centers in the width direction of the adjacent tie plates 14 is larger than the length in the width direction of the

cover plates

16, 20, and the interval between the edge portions in the opposing width direction is smaller than the length in the width direction of the

cover plates

16, 20, so that a part of the edge portions in the width direction of the

cover plates

16, 20 provided between and at the periphery thereof is lapped.

In this case, it is preferred that the length direction of the

cover plates

16, 20 is alongside the length direction of the mat 14.

Further, it is preferable that a sealing member 28a made of rubber, silicone, or the like is further provided at an edge portion in the width direction of the upper surface of the mat 14 so as to be in close contact with the bottom surface of the corresponding covering

panel

16, 20, thereby improving the airtightness of the greenhouse inside.

As described above, the pad 14 is fixed to the bracket 12b by a method such as forming a through hole (not shown) in the pad 14 corresponding to the bracket 12b, and then connecting the pad to the bracket 12b through the through hole by a fastening means (not shown) such as a wire, a bolt, and a nut, or welding the bracket 12b when the pad 14 is made of a metal material.

As shown in fig. 5a and 5b, a locking portion 14a having a shape curved upward may be formed at an edge portion in the width direction of the pad 14, and this locking portion 14a may be used to restrict a movement position of the recess portion 20a formed in the cover plate 20 by stretching or shrinking in the width direction in a modification described later.

It is preferable that the protruding height of the locking portion 14a is greater than the thickness of the mold frame 12a so that the

cover plates

16 and 20 do not interfere with the mold frame 12a in the process of fixedly disposing the backing plate 14 in contact with and supported by the outer periphery of the bracket 12 b.

On the other hand, the backing plate 14 can be arranged and fixed on the mold frame 12a so as to be aligned with the holder 12b with the above-described gap therebetween, and in this case, the backing plate 14 can be fixed to the mold frame 12a by a common clamping unit.

In the case where the mat 14 and the bracket 12b are arranged side by side, it is preferable that the

cover plates

16 and 20 arranged side by side in the longitudinal direction of the mat 14 be limited to a predetermined length, and the

cover plates

16 and 20 arranged continuously in the longitudinal direction of the mat 14 be disposed with a space therebetween in consideration of a temperature difference and a deformation amount of stretching and/or shrinking corresponding to the length of the

cover plates

16 and 20.

In contrast, it is preferable that the

cover plates

18 and 22, which will be described later, be provided in a shape corresponding to the mat 14 so as to cover the gap between the

cover plates

16 and 20 arranged in the longitudinal direction of the mat 14.

The mat 14 can be fixed to the support structure along the frame 12a and the support 12b in a grid-like manner like a go-kart, and the

corresponding cover plates

16, 20 are arranged in such a way that the shape corresponds to the area planned by the plurality of mats 14, so that the peripheral part of the bottom edge is supported, and the

cover plates

18, 22 are also arranged in a shape corresponding to the mats 14.

On the other hand, as can be confirmed in fig. 1 and 2a, the cover plate 16 of the present invention may be formed of a synthetic resin material (plastic material) having a set width, length and thickness different from those of the tie plate 14, and a plate material normally supplied in a roll form wound in the longitudinal direction may be used.

Further, the cover plate 20 shown in fig. 2b is formed with a recessed portion 20a, and the recessed portion 20a is formed in a recessed shape or a shape protruding upward at each portion where the space is left, as in the case of the surface of the cover plate 16, and protrudes or is recessed in a shape opposite to that when viewed from the upper surface, as in the bottom surface of the same portion.

As shown in fig. 2b to 5, the recess 20a of the cover plate 20 is formed on all surfaces of the cover plate 20, but is not limited thereto, and is preferably formed at least in a peripheral portion.

As shown in fig. 5a and 5b, the recessed portion 20a of the cover plate 20 is configured to function as a locking portion 14a formed at the edge portion in the width direction of the tie plate 14 so as to prevent the cover plate 20 from being detached to the outer periphery of the edge of the tie plate 14 supporting the cover plate 20 when the cover plate 20 is stretched or contracted due to thermal deterioration.

Further, it is preferable that a recessed portion 22a having a size smaller than that of the recessed portion 20a formed in the cover plate 20 is formed in the width direction edge portion of the cover plate 22 covering the recessed portion.

The reason why the size of the depression 22a formed in the cover plate 22 is made smaller in the manner as described above is to cope with a change in the tension or contraction of the cover plate 20 in the process of crimping the cover plate 20 between the cover plate 22 and the shim plate 14 by fixing the cover plate 22 to the shim plate 14.

That is, as shown in fig. 5a and 5b, the edge of the cover plate 20 is provided with a predetermined distance D1 corresponding to the structure such as the alignment groove 22b of the base plate 14 or the cover plate 22 in the width direction, and the predetermined distance D1 is formed on the side of the recess 20a of the cover plate 20 at the side of the recess 22a of the cover plate 22 that is to be fitted into the recess 20a of the cover plate 20, and a distance is maintained between the bottom surface side of the recess 20a of the cover plate 20 and the inner surface of the locking portion 14a of the base plate 14 corresponding thereto, so as to cope with the thermal expansion coefficient of the cover plate 20 due to the temperature difference between winter and summer.

However, as shown in fig. 2b to 5, the recessed portion 22a of the cover 22 is based on a shape recessed downward when viewed from above, but is not limited thereto, and may be configured to protrude upward in a manner opposite to the view of the recessed portion 22a of the cover 22, and in this case, the recessed portion 22a of the cover 22 may be formed at an interval capable of coping with the amount of deformation due to the thermal expansion, and may be larger than the size of the recessed portion 22a of the cover 22.

When the depressions 20a of the cover plate 20 are formed on the entire surface of the cover plate 20, the surface size of the cover plate 20 between the depressions based on the interval between the depressions 20a should be designed in consideration of the amount of deformation due to the thermal expansion.

Further, it is preferable that the sealing members 28 between the shim plate 14 and the

cover plates

16, 20 and between the

cover plates

18, 22 be provided at portions in face-to-face contact with the

cover plates

16, 20, not at portions corresponding to the recessed

portions

20a, 22 a.

When the

cover plates

16 and 20 are arranged side by side with the mold frame 12a, both end portions in the longitudinal direction thereof are provided at predetermined intervals from the ground surface at the edge of the cultivated land.

In this case, elastic members 26 for providing elastic force for stretching the

cladding sheets

16 and 20 in the longitudinal direction thereof between the

cladding sheets

16 and 20 and the support bars provided along the ground or other support structures provided separately are further connected to both end portions in the longitudinal direction of the

cladding sheets

16 and 20.

Furthermore, the space between the floor and the covering

panels

16, 20 is preferably separated from the outside by a unit of other plastic or floor or the like.

The tie bar 24 is provided on the backing plate 14 and the

cover plates

18 and 22, and the tie bar 24 is held in close contact by the

cover plates

16 and 20 that are pressed against each other at the widthwise edges of the backing plate 14 and the

cover plates

18 and 22.

Preferably, the connecting members 24 are formed at positions spaced apart from the widthwise central portions of the mat 14 and the

covers

18 and 22 in the longitudinal direction, and the connecting members 24 can also be formed as a unit for fixing the mat 14 to the bracket 12 b.

As shown in fig. 5a and 5b, the connecting member 24 is provided as a connecting relationship between a bolt 24a and a nut 24b, but is not limited thereto, and various means such as a rivet or a wire for achieving press-fitting fixation between the backing plate 14 and the

cover plates

18 and 22 may be used.

As described above, according to the structure of the present invention, the greenhouse structure 10 is formed by assembling and disposing the synthetic

resin material plates

14, 16, 18, 20, 22 to the mold frame 12a and the support 12b constituting the conventional vinyl house, and thus, not only is compatibility provided, but also rigidity and durability are stronger than those of plastic, so that it is possible to increase the lifespan by reducing the possibility of damage and breakage of the greenhouse structure, and also, in the case where partial damage and breakage occur, partial replacement is possible, thereby facilitating maintenance.
