Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixture for an upper roof sloped frame in a greenhouse and a support structure for the upper roof. The present invention relates to a mounting tool for attaching the sloped frame of the upper roof to the lower roof in a greenhouse having a double roof structure in which an upper roof is provided for roofing purposes, and a support structure for the upper roof.

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

In the lower roof 1, glass plates 12 are supported on top of inclined members (rafters) 11 provided at regular intervals, and the side edges of the glass plates 12 are held down by pressers 13. A glass plate 12 is fixed to the inclined member 11 by screwing to the member 11.

A support 6 made of a metal rod or metal pipe of a certain length is welded upright to the top surface of a metal base plate 61, and the base plate 61 is screwed to the top surface of the holding member 13 of the lower roof. 6 are set upright on the sloped surface of the lower roof and at regular intervals vertically and horizontally, and the sloped ribs 21 of the upper roof made of metal pipes are attached to the upper ends of each of these pillars 6 by suitable fixing fittings (not shown). are fixed, each of the inclined bones 21 is connected to each other at the upper end of the pillar 6 by a connecting rod 62 made of a suitable metal rod or metal pipe, and a light-shielding film 24 is placed on top of the connecting rod 62 to form the upper roof 2. There is.

"Problems 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. Since it is slanted, the load of the upper roof 2 acts on all the supports 6 exclusively in the direction of the roof hem, making the support structure weak.

Therefore, large-diameter metal rods or metal pipes must be used for the struts 6, and the struts 6 must be closely arranged on the upper surface of the lower roof 1. As a result, the load on the lower roof 1 increases accordingly, and the double roof structure itself becomes expensive.

Furthermore, it is preferable to make the sloped ribs 21 of the upper roof 2 into an arch shape so that the slope is slightly upwardly arcuate, since tension is easily applied to the light-shielding film 24. In this case, if the upper end of the strut 6 protrudes above the inclined bone 21, the light shielding film 24 will not be able to be stretched, so it is necessary to align the struts 6 of different heights, and furthermore, it is necessary to align the struts 6 of different sizes (lengths). It must be placed accurately to match the arch shape of the inclined bone 21.

An object of the present invention is to solve the above-mentioned problems, to support the upper roof more firmly with a lighter material, and to make the sloped bones of the upper roof into a gentle arch shape, or to An object of the present invention is to provide a mounting device for a sloped upper roof frame that can be used with the same size even when changing the floating interval of the roof, and a lightweight and more durable support structure for the upper roof using the mounting device. .

"Means for Solving the Problems" In order to achieve the above-mentioned object, the first fixture according to the present invention is bent into a substantially inverted V shape, and has a sloped rib of the upper roof at the top of the inverted V shape. A post made of a metal round bar, on which a support part for fixing is formed, and a horizontal base part extending outward or inward of the inverted V shape at both ends, and a pin holder in which the base part is rotatably guided. It is equipped with a pair of mounting brackets that are fixed to the upper surface of the lower roof.

Further, the second fixture according to the present invention has a substantially inverted V
Metal that is bent into an inverted V-shape, with a supporting part for fixing the sloped bones of the upper roof formed at the top of the inverted V-shape, and horizontal bases extending outward or inward of the inverted V-shape at both ends. A pair of pillars made of round rods and two pin holding parts, in which the base of each pillar is rotatably guided, are arranged in parallel with a predetermined distance apart, and are fixed to the upper surface of the lower roof. It is equipped with a mounting bracket.

In the first upper roof support structure according to the present invention, at least four of the above-mentioned first fixtures are arranged at predetermined intervals in a state in which the bases of the pillars are perpendicular to the inclination direction of the lower roof and the bases are parallel to each other. The mounting brackets of each fixture are fixed to the top surface of the lower roof, and the two pillars located on the lower side of the lower roof in the slope direction are connected to each other and the other two adjacent pillars are connected to each other. The slanted bones of the upper roof are fixed to the support portions of each support column in a state in which the pillars are opened upward.

Further, in the second upper roof support structure according to the present invention, at least two sets of the above-mentioned second fixtures are arranged in such a manner that the bases of the pillars are perpendicular to the inclination direction of the lower roof and the bases are parallel to each other. The mounting brackets of each fixture are fixed to the top surface of the lower roof at intervals of It is made by fixing the sloping bones of the hemlock roof.

"Operation" According to the first upper roof support structure using the first fixture and the second upper roof support structure using the second fixture according to the present invention, this When viewed from the side, it has a structure similar to a pin truss, and even when using supports of the same size, the upward opening of the adjacent supports (angle of inclination of the support relative to the slope of the lower roof) , the height from the lower roof to the upper roof sloped bone in this part can be selected as appropriate.

Further, according to the support structure of the upper roof according to the present invention, two spaces surrounded by each pillar in an inverted V-shape that is opened upward and the lower roof, and two spaces that are inclined with respect to each other of the adjacent pillars. If the two spaces surrounded by the bones are understood as virtual surfaces, the virtual surfaces form a tetrahedron in the portions of the mutual pillars that open upward. Therefore, even though each column is relatively thin, it becomes a very strong support structure, and the support structure of the upper roof itself can be made lighter.

This feature becomes particularly noticeable when two adjacent columns among four or more columns are arranged with a relatively narrow interval.

Embodiment FIG. 1 is an example of a supporting structure for an upper roof according to the present invention, and FIG. 2 is an example of a mounting tool for a sloped rib of an upper roof according to the present invention.

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

Attachments 3a are fixed at predetermined intervals on the upper surface of the lower roof 1 constructed as described above.

Each fixture 3a of this embodiment is bent into an inverted V shape as illustrated in FIG. A pair of pillars 3, 3 made of metal round bars each having a horizontal base 33 extending outward in the inverted V shape, and two pin holders in which the base 33 of each pillar 3 is rotatably guided. It is comprised of a pair of mounting brackets 4, 4, which have portions 41 in parallel with each other separated by a predetermined distance, and are fixed to the upper surface of the lower roof 1 with screws 43 (FIG. 3).

The support column 3 has two legs 31, 31 which are continuous with a horizontal support part 32 at the top and spread downward.
A base portion 33 extending horizontally outward is formed at the tip of the legs 31, 31.

In this embodiment, as illustrated in FIG.
The base 33 of the base 33 is rotatably guided.

A plurality of screw guide holes 42 are formed in the mounting bracket 4, and the mounting brackets 4 are held against the glass plate 12 with the pin holding portion 41 intersecting the slope of the lower roof 1 at right angles. Fix to the upper surface of the presser member 13 with screws 42 at desired intervals, and attach the base 3 of the support 3 to the pin holding portion 41 of the mounting bracket 4.
The fittings 3a are attached to the upper surface of the upper roof 1 at predetermined intervals by guiding the fittings 3 in a rotatable manner and caulking the ends of the fittings 3a so as to prevent them from coming off.

When manufacturing the fixture 3a, both legs 3 of the support 3
1 and 31 is set slightly wider than the state shown in FIG. 2, for example, the center distance L between the inclined members 11 of the lower roof 1, and the base 33 is attached to the pin holding part 41 of the mounting bracket 4 as shown in FIG. When guided, it is preferable that the support column 3 be in a tensioned state between the mounting brackets 4, 4.

The fixtures 3a are installed in two or more sets so that there are at least four columns 3 on one slope of the lower roof 1, and the lower two columns 3 in the slope direction are attached to each other and the other two columns 3 are attached to each other. are opened upward, and in this state, the inclined bones 21 made of metal pipes of the upper roof 2 are fixed to the support portions 32 of each support column 3 by appropriate means, and the inclined bones 21 are fixed to each other as shown in FIG. They are connected by a ridge material 22 made of a metal pipe as shown in FIG. 1, and also by an eaves material 23 having the shape shown in FIG.

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

To fix the inclined bone 21 to the support part 32 of the post 3, it is preferable to use a coupling device 5 as illustrated in FIG.

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, and has a U-shaped holding part 51 at both ends of which is pulled to the support part 32 of the column 3. Hook parts 52, 52 for hanging
The holding parts 53, 53 are extended through the holding parts 53, and the tips of the holding parts 53 are bent to face each other to form arc-shaped hooks 54, 54, and the U-shaped holding parts 5
1, the hooks 52, 52 are hooked from below to the support part 32 of the column 3, the presser parts 53, 53 are pulled upward, and the hook parts 54, 54 at the tips are tilted. The inclined bone 21 is fixed on the support part 32 by hooking it onto the bone 21. Due to the elasticity of the connector 5, the inclined bone 21 crosses over the support part 32 and is strongly fixed in point contact.

If the light shielding film 24 is not used depending on the season,
The sloped rib 21 can also be removed from the column 3 and removed, in which case the column 3 is left lying on the upper surface of the lower roof 1.

In this embodiment, the upper roof slope frame attachment and the upper roof support structure are such that the pair of columns 3, 3 are connected to the lower roof 1.
Since the sloped ribs 21 are fixed to the tops of the pillars 3, 3, the shape resembles a pin truss when viewed from the gable side of the greenhouse, and the pillars 3, 3 are tilted to open upward. By changing the angle Θ (the angle of inclination of the supports 3, 3), the floating interval w of the upper roof 2 from the lower roof 1 can be appropriately selected.

Further, the pillars 3, 3 which are opened upward are connected at their tops by an inclined bone 21, and each pillar 3, 3 is connected at the top by an inclined bone 21.
and the lower roof 1, each support 3,
If the space surrounded by the legs 31 of No. 3 and the legs 31 and the inclined bone 21 is understood as a virtual plane, the entire part of the fixture 3a forms a tetrahedron and becomes extremely strong. Therefore, the connecting rod 62 unlike the conventional structure shown in FIG.
It is possible to obtain sufficient strength to support the upper roof 2, and the load on the lower roof 1 can be further reduced.

For example, when the slope length of one side of the lower roof 1 is 6 m, the slope frame 21 is a metal pipe with an outer diameter of 19 mm and a wall thickness of 0.7 mm, and the light shielding film 24 is placed on top of the metal pipe,
Manufacture the struts 3 with metal rods (aluminum alloy) with a wire diameter of 5 to 6 mm, and install two sets of fixtures 3a on one slope of the lower roof 1 at intervals of 1.5 m in the ridge length direction, one on each ridge. It is sufficient to install each pair.

On the other hand, for example, the pin truss-like rod-shaped body connecting metal fitting disclosed in Japanese Utility Model Application Publication No. 164806/1980 has two rod-shaped bodies connected side by side, and as in the above-mentioned embodiment, it is not a tetrahedron. Therefore, the connection state is much weaker than in this embodiment.

For example, as shown in FIG. 7, when an arch-shaped sloped bone 21 is used for the upper roof 2, the sloped bone 21 is
If it is fixed, it is possible to use a support 3 of the same size.

Pin holding part 4 of the mounting bracket 4 in the fixture 3a
1 can be implemented even if it is in the form of a downward groove as shown in FIG. 4, or the support column 3 can be fixed to the lower roof with separate mounting brackets 4 as shown in the same figure and FIG. 8. It can also be implemented with a structure that

Further, the base portion 33 of the support column 3 may be bent inward of the inverted V-shape of the support column 3 as shown in FIG. 5. In this case, after guiding the base 33 to the pin holding part 41 of the mounting bracket 4,
The ends of the screws are crimped 34 or other means to prevent them from coming out.

In the embodiment described above, the paired support columns 3, 3 are placed close to each other, but this can also be done by mounting them with a wider gap as shown in FIG. 8, for example.

If the lower roof 1 is not a glass roof but a transparent corrugated roof made of synthetic resin, the pillars 3 are attached to the lower roof 1.
9 and 10, for example.

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

A base 1 made of hard rubber or synthetic resin with a shape that matches the required part of the upper surface of the corrugated plate 15 is installed.
6, a screw 43 made of a hook bolt is hooked onto the inward lip 17 of the purlin material 14, and this screw 43 is attached to the corrugated plate 15 and the base 1.
6. Fix the mounting bracket 4 on the lower roof 1 by passing it through the mounting bracket 4 and protruding upward by tightening the nut 44 on the screw 43, and attach the base 33 of the support post 3 to the pin holding part 41 of the bracket 4. It guides you in a freely rotatable manner.

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

Although each of the above embodiments has been described for a greenhouse with a glass roof and a greenhouse with a corrugated roof, the invention can also be applied to a greenhouse.

"Effects of the Invention" According to the upper roof sloped frame attachment device and the upper roof support structure according to the present invention, the upper roof can be installed very easily, and four pillars are installed on one slope of the lower roof. By installing the fixtures so that they line up and fixing the inclined bones with each two pillars open upward, each pillar in an inverted V-shape and the lower roof are opened upward. If we grasp the two spaces surrounded by the two spaces, the space surrounded by the adjacent pillars and the slanted bones, and the two spaces surrounded by the adjacent pillars and the slanted bones as virtual surfaces, In the parts of the mutual pillars that open upward, the virtual planes form a tetrahedron, so each pillar becomes a very strong support structure even though it is relatively thin, and the support structure of the upper roof itself. can be made lighter.

Furthermore, even when using fixtures of the same size, the floating distance from the lower roof of the upper roof can be appropriately selected by changing the upward opening angle between adjacent pillars.
