Description

The present invention relates to a trough for an agricultural house.

Conventionally, a valley gutter for an agricultural house has a substantially U-shaped cross section and is bent so as to have the same inclination angle of an arch pipe (Patent Document 1).

According to Patent Document 1, when the arch pipe is fixed to the trough, the film receiving member orthogonal to the film receiving member attached to the upper surface of the arch pipe is also fixed to the trough.

JP-A-2002-291348 (Fig. 7)

Therefore, conventionally, the work of attaching the film receiving member has been complicated.

Therefore, an object of the present invention is to eliminate the complexity of the work of attaching the film receiving member in an agricultural house.

The valley gutter for an agricultural house of the present invention made to achieve the above object is characterized in that it is formed in a U-shaped cross section having an upper opening and further has the following configuration.
(1) The U-shaped cross-section of the main body has a vertical portion forming at least a part of the side wall, a horizontal portion extending inward from the vertical portion, and an outward opening at the tip of the horizontal portion. The film receiving part and the film receiving part must be provided integrally so that they are symmetrical.

According to the valley gutter for an agricultural house of the present invention, the lower end of the film constituting the roof surface may be inserted beyond the roof side end portion of the valley gutter and fixed to the film receiving portion integrally provided by the valley gutter. .. Further, the film constituting the side wall of the house may be fixed to the film receiving portion integrally provided with the trough by allowing the upper end thereof to pass over the outer end portion of the trough and penetrate into the inside. Since the trough is provided with a film receiving portion so as to be symmetrical, the films on the left and right roofs and the film on the side wall on the eaves side can be fixed without blocking the opening of the trough. As a result, the complexity of the film receiving member mounting work can be improved.

Here, the valley gutter for an agricultural house of the present invention can further include the following configurations.
(2) A drain hole that penetrates in the vertical direction is formed in the horizontal portion.

The agricultural house trough of the present invention improves the complexity of the film receiving member mounting work, but on the other hand, a portion where water collects is generated between the film receiving portion and the vertical portion. , The new problem of "rainwater collecting in the horizontal part" can also be solved.

These agricultural house troughs of the present invention can further include the following configurations.
(3) The symmetrical film receiving portions are configured to be inclined upward so that the upper portions are separated from each other.

By providing such a configuration, the film mounting work can be facilitated, and the tip of the screw can be projected so as to be hidden behind the horizontal portion and the film receiving portion, so that the inspection work can be facilitated.

These agricultural house troughs of the present invention can further be provided with the following configurations.
(4) The main body portion is provided with a horizontal bottom surface portion, and an inner bottom portion separated from the bottom surface portion is integrally provided on the inner surface of the side wall, and a vertical portion connecting the inner bottom portion and the bottom surface portion. Must have a bottom structure with multiple box-like spaces.

By providing such a configuration, the trough can be directly attached to the top surface of the column by the horizontal bottom surface, and the strength can be increased by the bottom structure having a plurality of box-shaped spaces. It can also serve as an eaves gutter member. This simplifies the configuration of longitudinal structural strength members in agricultural houses.

On the other hand, in the central building 3 of both heavens, a film is put on the short arch pipes APS and APS extending from the valley gutter TT to the skylight receiver 25 to form the east-west roof surface.

The butt plates 22 and 22 have an area that protrudes vertically and horizontally from the gassho beams 21 and 21, so that flat plate-shaped bracket members 23 and 23 for supporting the skylight project outward at the upper ends, respectively. It is fixed by welding. Further, the central pillar UCP of the upper space is vertically fixed to the lower ends of the butt plates 22 and 22 via an angle member. The lower end of the central pillar UCP is joined to the lower beam member UB1 passed in the east-west direction between the main columns MP and MP. Further, the upper beam member UB2 passed in the east-west direction between the gassho beams 21 and 21 is also fixed at a position slightly above the middle of the central pillar UCP. A light-shielding curtain CTN is installed in the upper space, and a curtain winding device is installed in the vicinity of the main column MP of the lower beam member UB1. The upper center girder member UCG is also bolted to the west side surface of the butt plate.

As shown in FIGS. 2B, 2C, and 3, the bracket members 23, 23 projecting outward from the butt plates 22, 22 have a downward U-shape so as to be externally fitted from above. The outer fitting members 31, 31 are attached so as to be rotatable around the bolt shaft as a fulcrum. The bolt shafts are inserted so as to be located on the same horizontal axis in each of the plurality of pairs of gassho beams 21 and 21.

The upward U-shaped skylight receiving members 32, 32 are welded and fixed to the upper surfaces of the outer fitting members 31, 31 which are externally fitted to the bracket members 23, 23 from above. Then, the upper rails 33, 33 on the rotation fulcrum side of the skylight are fitted from above and fixed to the skylight receiving members 32, 32 by bolt tightening.

As shown in FIG. 4B, the skylights 5a to 5f have horizontal rails 34, 34, ... (4500 mm pitch) in the eaves direction in which the upper rail 33 and the lower rail 35 on the tip side are joined at each position of the gassho beam. It has an outer frame assembled in a ladder shape by. Although not shown, the hanging timber is assembled at an intermediate position (2250 mm pitch) between the cross rails 34, 34, .... Then, as shown in FIGS. 3A and 3B, a film receiving rail CUP is attached to the upper surface of the crosspiece members 33 to 35 with the opening facing upward. Although not shown, a film receiving rail CUP is also attached to the upper surface of the hanging timber attached at a pitch of 2250 mm with the opening facing upward. With these film receiving rails CUP, the film FLM can be stretched to the upper surface side of the skylight.

Further, as shown in FIG. 4B, a skylight receiving member 26 is also attached to the upper surface of the gassho beam 21. As a result, the skylight is closed with the crosspieces 33 to 35 receiving the lower surface by the skylight receiving members 25 and 26.

[Overview of Tanihi]
Next, the trough TT adopted in the agricultural house 1 of this embodiment will be described. The Tanihi TT is made of an integrally molded product made of an aluminum alloy, and as shown in FIGS. 5 (A) to 5 (C), the bottom surface portion 51 and the bottom surface portion 51 are opened diagonally about 45 degrees from both ends. The downward inclined portion 52, 52 extending, the vertical portion 53, 53 extending vertically upward from the upper end of the downward inclined portion 52, 52, and the upper end inclined portion extending diagonally about 45 degrees from the upper end of the vertical portion 53, 53. 54, 54, an inner bottom portion 55 connecting the insides of the downward inclined portions 52, 52, a central vertical portion 56 connecting the inner bottom portion 55 and the bottom surface portion 51, and horizontal from the inner surface side of the left and right vertical portions 53, 53. It has a symmetrical cross-sectional shape consisting of horizontal portions 57, 57 extending in the horizontal direction and film receiving portions 58, 58 formed so as to open outward at the tips of the horizontal portions 57, 57, and has a symmetrical cross-sectional shape in the length direction. It has a total length (4500 mm) that can be hung between the main columns MP and MP. The width of the bottom surface portion 51 is the same as the width of the top surface of the main support column MP.

Bolt insertion holes for fixing the lower ends of the arch pipes APS and APL by bolting are penetrated in the upper end inclined portions 54 and 54 at predetermined positions in the length direction. Further, at both ends of the downwardly inclined portions 52 and 52 in the longitudinal direction, gassho mounting holes 71 and 71 for inserting bolts and the like when mounting the gassho beams 21 and 21 are also formed. Further, as shown in FIG. 5C, a drain hole 59 is penetrated in the vicinity of both ends in the length direction and the vicinity of the center in the length direction of the horizontal portions 57, 57.

As shown in FIG. 5C, the film FLM is pushed into the film receiving portion 58 from the outside and then fixed by the fixing spring SPR. Further, the cover member CAP is further fitted into the film receiving portion 58 from the outside, and is fixed by screwing with a screw BIS. At this time, the tip of the screw BIS protrudes to the back side of the film receiving portion 58, and the portion is a blind space 60 on the back side of the horizontal portion 57 and the film receiving portion 58.

The bottom portion of the trough TT is formed into two box-shaped spaces by the bottom surface portion 51, the downward inclined portions 52 and 52, the inner bottom portion 55, and the central vertical portion 56. By providing this box-shaped space, the bending strength of the valley gutter TT is enhanced, and by being joined to the gassho beam, it also serves as an eaves girder member.

Since the Tanihi TT integrally includes the film receiving portions 58, 58 on the inner surface of the vertical portions 53, 53 via the horizontal portions 57, 57, work such as attaching the film receiving rails becomes unnecessary. The integrated structure of the vertical portions 53, 53 and the film receiving portions 58, 58 via the horizontal portions 57, 57 also contributes to the improvement of the strength of the valley gutter TT. The drain holes 59 provided in the horizontal portions 57 and 57 are effective as a means for solving a new problem that "rainwater collects in the horizontal portions 57 and 57 provided for improving convenience and strength". ..

[Action / effect of Examples]
Next, the actions and effects of the examples will be described.

(1) Increasing the size of the skylight In this embodiment, the bracket member 23 projecting the rotation fulcrum side of the skylights 5a to 5f from the upper part of the butt member 22 provided at the upper end joint of the gassho beam 21 toward the outside. In addition to the above, the skylights 33 to 35 are configured to be received by the skylight receiving members 25 and 26 attached to the gassho beam 21, so that the skylight can be enlarged.

As a result, as shown in FIG. 6 (A), in the applicant's experimental field (area under confidential control due to restricted access), the crosspiece members 33 to 35 are made of steel with a thickness of 75 mm × 45 mm and a plate thickness of 1.6 mm. It has become possible to use a square pipe assembled in a form in which the longer side is laid on its side, and the largest skylight can have a width of 1500 mm and a length of 18000 mm. In this example, as the skylight receiving members 25 and 26, a steel square pipe having a thickness of 75 mm × 45 mm and a plate thickness of 1.6 mm is attached with the long side sideways as in the case of the crosspiece member.

This makes it possible for an operator to ride on the crosspiece of the skylight when working on the roof. Further, as can be seen from FIG. 6A, there is no arch pipe in the opening under the skylight, and the daylighting property is greatly improved. In FIG. 6A, the reference numeral NET is an insect repellent net attached between the lower rail 35 of the skylight and the horizontal rails 34 at both ends and the skylight receiving members 25 and 26. From FIG. 6A, it is clear that the arch pipe does not exist in the portion of the insect repellent net NET, and the daylighting property is improved. Further, by using the bracket member 23 as the rotation support portion, the skylight can be opened widely, and the ventilation efficiency can be improved by the size of the opening in addition to the size of the opening.

(2) Improvement of workability by the film receiving integrated valley gutter Figure 6 (B) shows the film for the valley gutter TT of the example in the applicant's experimental field (area under confidential control due to restricted access). It shows a stretched state. Since the film receiving portions 58 are provided on the vertical portions 53 and 53 on both sides of the trough, the trough TT can be used for fixing the upper end of the film FLM2 on the side wall side in addition to the film FLM on the roof side. As a result, it is not necessary to separately attach a film receiving rail like the upper end of the side wall of the house. Further, since the tip of the screw BIS is not exposed due to the blind space 60, the safety is enhanced and the workability in the inspection work and the like is also improved.

(3) Drainage hole in the horizontal portion of the trough In the embodiment, a drainage hole 59 is provided in the horizontal portion 57 provided for the film receiving integrated type, and a new problem of "rainwater collects in the horizontal portion" is solved. Has also been resolved.

(4) Effect of reducing the number of parts by the skylight receiving member and the valley gutter The skylight receiving member 25 and the valley gutter TT joined to the gassho beam 21 and the main strut MP have the functions of the skylight receiving member and the valley gutter, as well as agriculture. It also functions as a structural strength member in the longitudinal direction in the house 1. As a result, it became possible to simplify the configuration for exerting the structural strength of the house, and it became possible to reduce the number of parts of the entire house.

In the agricultural house of the second embodiment, as shown in FIG. 7, the gassho beam joint fitting has a downward U-shaped cross section and is combined in a V shape corresponding to the roof inclination of the joint of the gassho beams 21 and 21. A plate-shaped member 82 is attached so as to be sandwiched between 81 and 81, and a metal fitting having a U-shaped cross section is attached to the surface of the plate-shaped member 82 so that the open side of the U-shape faces outward. It constitutes the roof side joining metal fittings 83 and 83. On the sky window side, a flat plate-shaped window-side joint fitting 85 is attached to the lower surface of the upper rail 33. The window-side joint fitting 85 is welded and fixed at intervals of 4500 mm in the length direction of the upper rail.

Then, the gassho beams 21 and 21 are attached to the gassho beam joint fittings 81 and 81 by inserting them, and the gassho beams 21 and 21 and the gassho beam joint fittings 81 and 81 are fastened with a plurality of bolts, respectively.

After joining the upper ends of the gassho beams in this way, insert the window-side joint fitting 85 into the roof-side joint fitting 83 so that it is inserted into the U-shape, and fix it with one bolt each. At this time, at the upper end joints of the gassho beams installed at intervals of 4500 mm with respect to the length direction of the house, all the bolt insertion holes 84 formed in the roof side joint fitting 83 are located on the same axis in the horizontal direction. I'm trying to get my heart out. This centering is easily achieved by joining the upper end portions of the gassho beams 21 and 21 using an integral gassho joining metal fittings 81 and 81 and a plate-shaped member 82. As a result, these bolts are located on the same axis even though they are connected by bolts at a plurality of points in the length direction of the house.

(5) Effect peculiar to Example 2 The joining of the upper ends of the gassho beam and the axis alignment of the roof side joining metal fittings become easy, and the rotation angle of the skylight in the opening direction can be further increased.

(6) Overall effect in each embodiment From these actions and effects, it is possible to reduce the construction cost of the agricultural house.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and it goes without saying that various forms can be further adopted within a range not deviating from the gist thereof.

For example, the trough may be a molded product made of a metal other than an aluminum alloy, or may have an integral structure by welding. It is also possible to use only the eaves gutter.

It can be used for agricultural cultivation equipment.
