Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for a top roof support and a double roof in a greenhouse, and more specifically, for example,
In a greenhouse with a double roof structure, such as a greenhouse with a mud roof for placing a light-shielding film, cheesecloth, etc. on the lower roof, it relates to columns for supporting the upper roof on the lower roof, and a support structure for the upper roof. It is something.

``Prior art J'' In a conventional greenhouse, for example, when a sloped frame of the upper roof is provided in a floating state above a glass roof, etc., and a light-shielding film is placed on top of this sloped frame, a support as shown in Fig. 11 is used. It has a structure.

In the lower roof 1, the glass plates 12 are supported on top of the inclined members (rafters) 11 provided at regular intervals in the direction of the ridge, and the gJ1 end of this glass plate I2 is pressed with a presser I3. The glass plate 12 is fixed to the inclined member 11 by screwing the glass plate 12 to the inclined member 11.

A support 6 made of a metal rod or a metal vibrator of a certain length is welded upright to the upper surface of a metal substrate 61, and the substrate 61 is screwed to the upper surface of the holding member 13 of the lower roof. The pillars 6 are placed upright against the slope of the lower roof and are placed at regular intervals vertically and horizontally, and each of the pillars 6
The tilted bones 21 of the upper roof made of a metal vibrator are fixed to the upper end using suitable fixing fittings (not shown), and each tilted bone 21 is
The upper ends of the pillars 6 are connected to each other by a connecting rod 62 made of a suitable metal rod or a metal bike, and a light-shielding film 24 is stretched over the connecting rod 62 to form the upper roof 2.

"Problem to be Solved by the Invention" In the conventional support structure described above, each support column 6 stands upright with respect to the slope of the lower roof 1, and with respect to the horizontal plane, it only moves in one direction by the slope of the roof. Because it is sloping, the upper roof 2
The load is 41 exclusively for all columns 6! It only acts in the direction of the hem, and the support structure is weak.

Therefore, a large-diameter metal rod or a metal vibrator must be used for the strut 6, and the strut 6 must be closely arranged on the upper surface of the lower M root 1. Due to the necessity of interconnecting the roofs, the load on the lower roof l increases accordingly, and the double roof structure itself becomes expensive.

Also, it is preferable to make the sloped ribs 21 of the upper roof 2 into an arch shape so as to be slightly upwardly arcuate, since tension is easily applied to the light-shielding film 24. If so, is the upper end of the support 6 or the slope f?
If it protrudes above -21, the light-shielding films 2 and 1 cannot be stretched, so it is necessary to align the struts 6 of different heights, and furthermore, the struts 6 of different sizes (lengths) are arranged in the arch shape of the inclined bone 21. Must be placed accurately to fit.

Furthermore, when changing the floating distance W of the shed jfi2, it is necessary to prepare a support column 6 of a size that matches the change.

An object of the present invention is to solve the above-mentioned problems and to provide stronger support for the upper roof using a lighter material. To provide a support structure for an upper roof and a supporting structure for an upper roof, which can be used with supports of the same size even when the floating interval of the roof is changed.

"Means for Solving the Problems" In order to achieve the above-mentioned object, the support for the upper roof according to the present invention is a round metal bar bent into a substantially inverted V shape, and the support for the upper roof is attached to the top of the rod. Forms a support part to fix the inclined bone of 5
Means is adopted for forming horizontal bases extending outward or inward of the inverted V shape at both ends.

In addition, in order to achieve the above-mentioned object, the support structure for the upper roof according to the present invention is made of a metal round bar bent into a substantially inverted V shape, and has a support structure at the top that supports the sloped bones of the upper roof. The pillars each having a horizontal base extending outwardly or inwardly of the inverted V-shape at both ends thereof are arranged so as to overlap the inverted V-shape toward the upper surface of the lower roof in the direction of its inclination. At least four pillars are arranged at desired intervals, and each pillar is attached to the upper surface of the lower roof so as to be swingable in the direction of inclination thereof, and at least two of the pillars and the other pillars are connected to the slope of the lower roof. upward aIj! to the support portion of each of the pillars in a state where they are tilted in opposite directions to each other. A means of fixing the tilted bone is adopted.

In the support structure, in order to attach the support column to the upper surface of the lower roof so as to be able to swing in the direction of its inclination, a mounting bracket having a pin holding portion formed at a right angle to the slope of the lower roof is attached to the upper surface of the lower roof. It is preferable that the base of the support column is rotatably guided to the bottle holder described in +iii.

In addition, among the four or more pillars in the support structure, each two adjacent pillars are arranged close to each other and the number of the lower roof pillars is
It is preferable to incline the two pillars toward each other upward with respect to the J side slope, and in this state, fix the sloped material of the earthen roof to the support part of each pillar.

Preferably, metal vibrators are used for the sloped members of the upper roof.

E Effect J The pillars of the above structure according to the present invention are arranged such that four or more pillars are arranged at desired intervals in the above-mentioned inverted V shape or overlapping toward the upper surface of the lower roof in the direction of inclination thereof, and each pillar is arranged in the above-mentioned manner. Each of the pillars is attached to the upper surface of the lower roof so as to be swingable in the direction of its inclination, with at least two of the pillars and the other pillars tilting in opposite directions relative to the slope of the lower roof. The upper roof supporting structure according to the present invention is obtained by fixing the sloped bones of the upper roof to the supporting portion of the upper roof.

Therefore, one part (two) of the pillars and the other pillars are tilted towards the bottom of the roof and the other towards the line, and the sloped bones of the upper roof fixed to the support at the top of the pillars allow , the mutual supports with different inclination directions have a structure similar to a truss when viewed from the gable side, and the space formed by the mutual inverted V-shaped supports with different inclination directions and the inclined bones. If we understand it as a virtual surface, it forms a kind of polyhedron, so even though the pillars themselves are relatively thin, they are extremely strong, and the supporting structure of the upper roof itself can be made lighter.

This feature is achieved by arranging two adjacent pillars of four or more pillars close to each other, and slanting the two pillars upward toward each other in a way that spreads out toward the bottom of the slope of the lower roof. 6 also becomes noticeable when Even when using posts of the same size.

By changing the angle of inclination of the support columns with respect to the slope of the lower roof, it is possible to adjust the floating distance of the upper roof from the lower roof, and also to adjust the angle of inclination of the supports at the center of the slope of the lower roof when viewed from the gable side. If you increase #41 on the upper roof.
Even if it has 4 bones or a gentle arch shape, it can be assembled accordingly.

"Example" No. 113 is an example of a roof board support structure according to the present invention,
FIG. 2 is an example of a support column according to the present invention.

In FIG. 1, the inclined members 11 of the lower roof l are supported by a main building material (not shown) and are provided at regular intervals (for example, 50 cm apart). Glass plates 12 are supported between the inclined members 11, and the glass plates are The glass plate 12 is fixed to the upper surface of the inclined member 11 by pressing the end portion of the glass plate 12 with a holding member 13 and screwing the holding member 13 onto the inclined member 11. A skylight (not shown) may be provided in the ridge of the lower roof 1.

On the upper surface of the lower roof l configured as described above, a support 3 made of a metal round bar bent into an inverted V shape as illustrated in FIG. At least four pillars are arranged so as to overlap in the inclination direction and at appropriate intervals, and two pillars are also arranged in the ridge part, and each of these pillars 3
is attached to the upper surface of the lower roof l so that it can swing in the diagonal direction.

The pillar 3 has a horizontal support part 3 at the top as shown in FIG.
At the tips of both legs 31, which form a shape of 2 and spread downward, base portions 33 extending horizontally outward are formed.

In this embodiment, as illustrated in FIG.
This mounting bracket 4 is fixed to the upper surface of the presser member 13 that presses the glass plate 12 at a desired interval with screws 42 in a state where the bottle holding part 41 intersects the slope of the lower roof 1 at right angles. By guiding the base 33 of the support 3 to the bottle holding part 41 of the mounting bracket 4 in a rotational direction and caulking its tip to prevent it from coming out, the support 3 can be freely swung toward the upper surface of the upper roof 1. It is installed on. When manufacturing the support column 3, the distance between the two legs 31 is set slightly wider than the state shown in FIG.
When the base 33 is guided to the bottle holding portion 41 of the mounting bracket 4 as shown in the figure, it is preferable that the support 3 or the mounting brackets 4 and 4 be stretched between each other.

At least four pillars 3 are installed in a row on one slope of the lower roof l, and two of them and the other two are tilted once in opposite directions to the slope of the lower roof l. In this state, the inclined bones 21 made of fully bent pipes of the upper roof 2 are fixed to the support portions 32 of each pillar 3 by appropriate means, and the inclined bones 21 are connected to each other with a ridge member 22 made of a fully bent vibrator. The rod members 23 having the shape shown in FIG. 1 are used for connection.

A light-shielding film 24 whose upper end is fixed to the ridge material 22 is stretched over the inclined rib 21 to form the upper roof 2, and a winding shaft 2a is fixed to the hem of this light-shielding film 24. 2af
: It is rotated by a winder (not shown) to wind up or unwind the light shielding films 2 and 1 to open and close them.

In this embodiment, there are 3 or 2 pillars in pairs, and 6
The distance between the pairs of columns 3, 3 is made close to each other, the bases 33 of each other are supported by a common mounting bracket 4, and the six pairs of columns 3, 3 are arranged in opposite directions so as to diverge upwardly. The #4 oblique bone 21 is supported in a tilted state.

In order to fix the inclined bone 21 to the support part 32 of the strut 3, the sixth
It is preferable to use a connector 5 as illustrated in the figure.

The connector 5 is integrally made of an elastic metal wire and has a U-shaped holding part 51 that holds the inclined bone 21.
The holding parts 53 and 53 are extended through hook parts 52 and 52 hooked onto the support part 32 of the pillar 3 at both ends of the holding part 51, and the tips of the six holding parts 53 are bent to face each other to form arc-shaped hooks. 54.54, and the inclined bone 21 is located below the U-shaped holding part 51. : Guide it, then hook the hook part 52.52 from below to the support part 32 of the column 3,
Pull up the presser part 53.53 and hook part 54 at the tip
．． 54 is hooked onto the inclined bone 21 to fix the inclined bone 21 onto the support portion 32. Due to the elasticity of the connector 5, the inclined bone 2
1 is strongly fixed on the support part 32 in a cross-point contact state.

If the light shielding film 24 is not used for convenience, the inclined bone 2
1 can also be removed from the support column 3 and removed; in this case, the support column 3 will be in a state of being collapsed onto the upper surface of the lower roof l.

In this embodiment, the upper roof struts and support structure are tilted in opposite directions with respect to the tilted surface of the lower roof 1, and the tilted ribs 21 are fixed to the tops of the struts 3, 3. When viewed from the gable side of the greenhouse, it has a shape similar to a pin truss.
1, and if we consider the plane connecting the legs 31 of the struts 3, 3 and the legs 31 to the inclined bone 2 as an imaginary plane, the entire structure forms a polyhedron and is extremely strong. Therefore, there is no need for the connecting rod 62 as in the conventional structure shown in FIG. It is possible to reduce the load on the

For example, when the sloped rib 21 is a scrap metal pipe with a slope length of 6 m on one side of the lower roof l, an outer diameter of 19 mm, and a wall thickness of 0.7 tmti, and the light-shielding film 24 is stretched over it, the wire diameter is 5 to
Manufacture pillar 3 with 6 metal rods (aluminum alloy) and 1
It is sufficient to attach four columns 3 to one slope of the lower roof 1 and two columns to the ridge at intervals of 1.5 m in the ridge length direction.

Also, for example, as shown in Figure 7, a shed! When using arch-shaped osteoid 21 for fi2, by fixing the inclined bone 21 while changing the inclination angle of the support 3 with respect to the lower roof l, it is possible to use the same size support 3. As shown in FIG. 1, the floating interval W of the shed Mi2 can be adjusted by changing the angle θ formed by the pillars 3° and 3 with respect to each other.

The bottle holding part 41 of the mounting bracket 4 may be shaped like a downward groove, for example, as shown in FIG. It can also be implemented with a structure fixed to the roof.

Further, the base portion 33 of the support column 3 may be bent inside the inverted V-shape of the support column 3 as shown in Fig. 85. In this case, the base 3 is attached to the bottle holding part 41 of the mounting bracket 4.
After guiding the base part 3, it is necessary to make the end of the base part 33 preventable by caulking 4 or other means.

In the above embodiment, the paired support columns 3, 3 are placed close to each other, or
This can be done, for example, by mounting the parts at wide intervals as shown in FIG.

Moreover, four or more pillars 3 for supporting the sloped ribs 21 are provided on one sloped surface of the lower roof 1, and two of them and the others are arranged in the opposite direction to the sloped surface. , ji
Since it is sufficient if the pillar 3 is
It can be carried out even if they are not provided in pairs, and if five or more pillars 3 supporting the sloped wooden ribs 21 are provided, more than four pillars can be installed with respect to the sloped surface of the lower roof 1. Can be performed upright or mixed.

If the lower roof 1 is a transparent corrugated roof made of synthetic resin, the supports 3 are attached to the lower roof 1 as shown in FIGS. 9 and 10, for example.

In both figures, purlins 1=1 made of C-shaped members are fixed at predetermined intervals on top of the inclined member 11 of the lower roof 1, and a transparent corrugated plate 15 is attached on top of the purlins 14.

Attachment fittings 4 are provided at required portions of the upper surface of the corrugated plate 15 via bases 16 made of hard rubber or synthetic wood with a shape that matches the fittings, and hook bolts 43 are pulled into the inward facing sops 17 of the main building material 14. and attach this hook bolt 43 to the corrugated plate 15 and the base 16. The mounting bracket 4 is fixed on the lower roof 1 by passing through the metal fitting 4 and protruding upward, and the nut 44 is tightened on the hook bolt 43, and the base 33 of the support column 3 is rotated to the bottle holding part 41 of the metal fitting 4. I guide you freely.

The other structures and operations in the embodiments shown in FIGS. 9 and 10 are the same as those in the example shown in FIG. 1, and therefore their explanations will be omitted.

Although each of the above embodiments has been described for a greenhouse with a single glass roof and a greenhouse with a corrugated roof, it can also be implemented for a greenhouse.

"Effects of the Invention" The upper roof supports according to the present invention are arranged such that four or more supports are arranged on the upper surface of the lower roof so as to overlap in the direction of inclination thereof and are attached so as to be able to swing. The work is simple, as all you have to do is fix the sloped bones of the upper roof to the top of the sloped surface in a state that is inclined in the opposite direction to the sloped surface. It can be strongly supported.

In addition, the support structure according to the present invention has a structure similar to that of a bin truss, such as the sloped bones of the pillars and the upper roof, and the pillars and sloped bones form a kind of polyhedron when viewed from above, so it is very difficult to use materials that are difficult to measure. become stronger. Therefore, coupled with the fact that there is no need to connect the tilted bones with each other using a connecting rod, the load on the lower roof can be further reduced.

Furthermore, even when using columns of the same size, by changing the angle of the columns, it is possible to change the floating distance of the upper roof, and even if the columns are slanted or arched, the angle of the columns can be changed. It can be made to correspond to this.
