Description

[Detailed explanation of the invention] This invention was designed to construct the frame of a greenhouse, more specifically, to erect horizontal beams with a square cross section between the main pillars erected on the ground, and to support the roof frame made of pipes on the horizontal beams. Concerning the frame of a greenhouse.

Conventionally, in the framework of this type of greenhouse, the angle at which the roof frame is attached to the horizontal beams is limited to a predetermined angle (usually a right angle).

However, when assembling a greenhouse on flat land, there is not much of a problem, but when assembling it on a undulating land such as a mandarin orange orchard that has both a sloping land and a flat land, the horizontal rod a is parallel to the undulating ground as shown in Figure 1. Since it is constructed via a plurality of supports C, the roof frame d, which is supported perpendicularly to the horizontal beam a, is inclined at the sloped material surface area, and therefore, the sloped ground area may be damaged by wind or the like. There is a risk that the roof frame d may collapse.

In view of the above points, the present invention has been developed so that the roof frame can be attached to the horizontal beam at any angle, and can be firmly attached at any angle. The ribs are installed vertically parallel to the roof ribs on other horizontal areas to prevent the roof ribs from collapsing due to wind or other factors.

The details of the present invention will be explained below based on the embodiments shown in the drawings.

First, Fig. 2 shows the assembled state of a vinyl house on a undulating land (C) consisting of a slope (A) and a flat entrance. The horizontal beams 4, 4 having a square cross section are erected on the main pillars 2 of each row via a large number of supporting metal fittings 3. do.

A large number of semicircular arc-shaped roof ribs 6 made of pipes are fixed to each of the horizontal bars 4, 4 via a large number of mounting brackets 5 so as to straddle the horizontal bars 4. The vinyl house 1 is constructed by covering the plastic sheet 7 to cover the columns 4, 4, and each of the pillars 2.

As shown in detail in FIG. 3, the support fitting 3 for installing the horizontal rod 4 on the main pillar 2 has side pieces 32° 32 at both ends of the opening side of a U-shaped fitting part 31 to fit onto the horizontal rod 4. The fitting portions 31 are fitted into the horizontal rod 4, and with the side pieces 32 and 32 in contact with both sides of the upper part of the support column 2, Each piece 32.32
The horizontal rod 4 is fixed to the column 2 by screwing bolts 33, 33 into the upper and lower portions of the rod, respectively.

A long hole 34 that draws a semicircular locus with the upper bolt 33 as the center is formed in the lower side of the side piece 32 of the support fitting 3, and the lower bolt 33 is screwed between the long holes 34. This makes it possible to adjust the attachment angle of the support fitting 3 to the column 2, that is, the attachment angle of the horizontal rod 4, within the range of the elongated hole 34.

As shown in detail in FIGS. 4 and 5, the attachment fitting 5 for fixing the roof frame 6 to the horizontal beam 4 includes a metal fitting main body 51 having a U-shaped cross section to fit onto the horizontal beam 4, and The wedge body 52 has a U-shaped cross section and is inserted between the lower facing walls to fix the metal fitting body 51 to the horizontal rod 4.

Therefore, the opposing side wall 53° 53 of the metal fitting main body 51
At the lower end of each of the engagement grooves 54.54, a portion thereof is bent inward to form an engagement groove 54.54 having a U-shaped cross section.
The metal fitting 5 is fixed to the horizontal rod 4 by inserting the side plates of the wedge body 52 into the metal fittings 4 and press-fitting the wedge bodies 52 into the metal fitting main body 51.

Further, the lower part of the opposing side wall 53 of the metal fitting main body 51 is formed wider than the horizontal rod 4 so that it can easily fit into the horizontal rod 4, while the outer side of the side wall 53 bulges outward. A through hole 56 is formed in the center of the protruding portion 55, and a chrysanthemum-shaped unevenness 57 is formed around the through hole 56 on the outer surface side of the protruding portion 55.
form.

On the other hand, as is clear from FIG.
At the same time, a through hole 6 is formed on the inner surface side of the flat part 61.
2, there are provided unevenness 63 that engages with the unevenness 57 of the bulged portion 55.

Then, the flat part 61 of the roof frame 6 is brought into contact with the bulge part 55 of the mounting fitting 5, and the bolt 8 is inserted from the inside of the bulge part 55 across both the through holes 56 and 62. The roof frame 6 is fixed to the mounting fitting 5 by screwing a nut 10 onto the insertion end of the bolt 8 through a washer 9.

The above framework will be assembled as follows.

First, two rows of multiple pillars 2 are erected at equal intervals on the sloping ground A and the flat ground entrance of the undulating land C, and using the supporting metal fittings 3 as described above on the top of each row of pillars 2, the pillars 2 are placed parallel to the undulating land C. Each horizontal beam 4 is constructed so that

Next, a plurality of mounting metal fittings 5 are fitted at a plurality of positions on each of the horizontal rods 4 at equal intervals, and the metal fitting bodies 51 thereof are fitted, and a wedge body is fitted along the engagement grooves 54.54 of the opposing side wall 53.53. 52
It is fixed by press-fitting into the metal fitting 5.

After that, the mounting brackets 5, 5 were fixed to each of the horizontal bars 4.4.
Both ends of the roof frame 6 are brought into contact with each of the bulges 55 and 55 of the metal fittings 5 so that the respective projections and recesses 57 and 63 are engaged with each other.
The bolts 8 are inserted between the through holes 56 and 62 of the roof frame 6, and the nuts 10 are screwed onto the ends of the bolts 8 to fix the bolts, respectively.

At this time, the roof ribs 6 are fixed parallel to each other and perpendicular to each other on the sloping ground and the flat ground.

That is, on a sloping site A, the roof frame 6 is fixed vertically by rotating around the bolt 8 and tilting it at a predetermined angle with respect to the horizontal beam 4.

The roof rib 6 and the mounting bracket 5 are provided with concave and convex portions 57 and 63 on their opposing surfaces, respectively, and the concave and convex portions 57 and 63 are interlocked with each other, so that the roof rib 6 does not rotate freely. ,
It is held in the tilted position.

After this, a vinyl sheet 7 is placed on the roof frame 6, horizontal beams 4, and pillars 2.
The plastic house 1 is made by covering the plastic.

As explained above, the present invention involves fitting the main body of the mounting bracket, which has a U-shaped cross section, onto a horizontal beam installed on a support post, and inserting a wedge body between the opposing walls of the bracket to secure the mounting bracket to the horizontal beam. By doing so, it is not only possible to easily attach the mounting bracket to the horizontal beam, but also to securely fix the mounting bracket.

In addition, a bulging portion is formed on the side wall of the mounting bracket, and the end of the roof rib is made flat, and unevenness that engages with the flat portion and the bulging portion is formed on the opposing surface. The roof frame was fixed to the mounting bracket by inserting a bolt between the bulges and screwing the oak I. into the inserted end, so the attachment angle of the roof frame to the horizontal beam could be changed freely. It can be firmly fixed at any angle.

Therefore, when assembling a greenhouse on undulating land, it has become possible to fix each roof frame vertically so that each frame is parallel to the other, thereby preventing the roof frame from collapsing due to wind.
