2. Description of the Related Art In recent years, in plant horticulture cultivation, crops are often cultivated by isolating a medium from soil, such as nutrient solution cultivation, in contrast to conventional soil cultivation. In order to isolate the culture medium from the soil, a block is installed, a cultivation container is placed thereon, and the culture medium is put in the cultivation container. In the present specification, a medium in which a culture medium is placed in a cultivation container is referred to as a cultivation bed. In the cultivation of crops, when it is necessary to increase the height of separating the cultivation bed from the soil to some extent, a combination of pipes and various joints is used to form a mount and mount the cultivation bed on the mount. ing. Conventionally used pipes are galvanized steel pipes for agricultural use which are relatively inexpensively available.

Conventionally, as a frame, a plurality of ramen having two cross beams on two legs as shown in FIG. 6 are arranged in the longitudinal direction as shown in FIG. It was connected and installed.

[0004] Generally, cultivation beds in greenhouse horticulture are:
While the width is about 30 to 150 cm, it is 30 to 40 m or more in the longitudinal direction. Since such a cultivation bed frame has a considerable weight, the cultivation bed is required to have strength to withstand the weight. Therefore, conventionally,
The number of legs of the gantry, that is, the ramen, was increased.

[0005] When installing the above-mentioned gantry, at the installation location, a ramen is made by assembling steel pipes and the like, and after the ramen is made to stand on its own, the ramen is connected by beams. In order to make the ramen self-supporting, for example, as shown in Japanese Patent Application Laid-Open No. 9-23770, a seat plate is provided at the ground portion of the ramen, and a pipe of a leg portion of the ramen is fitted to the seat plate. ing.

SUMMARY OF THE INVENTION As mentioned above,
Conventionally, the installation of the cultivation bed stand took a long time to install because a steel pipe or the like was assembled at the installation location, and the work efficiency was poor. An object of the present invention is to provide a cultivation bed base that can be installed easily with a short time required for installation.

[0007]

The cultivation bed base of the present invention is characterized by a ramen serving as a leg thereof. In the ramen, as shown in FIG. 4, the grounding portions 1 and 5 are perpendicular to the plane formed by the leg portions 2 and 4 and the cross beam portion 3 of the ramen, and the grounding portions 1 and 5 are connected to each other. It is of a shape that is symmetric with respect to the plane and is self-supporting.

The cultivation bed stand of the present invention can be installed simply by installing the above-mentioned ramen at an installation place at a required interval by calculating from the weight of the cultivation bed installed on the stand and connecting them with beams. Good. The time required for installation is reduced as compared with the conventional cultivation bed stand.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A ramen serving as a leg of a cultivation bed stand of the present invention can be manufactured by bending a single pipe as follows. As shown in FIG. 2, the points at which one pipe 10 is bent are defined as a bending point 6, a bending point 7, a bending point 8, and a bending point 9. Part 2, cross beam part 3,
The leg portion 4 and the contact portion 5 are provided. The length of the horizontal girder portion 3 is equal to or greater than the width of the cultivation container placed thereon, and the length of the leg portions 2 and 4 is such that the cultivation bed has a good workability according to the type of crop to be cultivated. The length of the ground contact portions 1 and 5 may be a length necessary for the ramen to stand on its own. First, the pipe 10 is bent at the bending points 7 and 8 on the same side by 90 degrees each. As a result, a plane constituted by the cross beam 3 and the legs 2 and 4 of the ramen is formed. Next, the pipe 10 is bent at 90 degrees at bending points 6 and 9. At this time, the grounding portions 1 and 5 are perpendicular to the plane formed by the cross beams 3 and the legs 2 and 4 of the rigid frame, and the grounding portions 1 and 5 are symmetric with respect to the plane. The pipe 10 is bent at bending points 6 and 9. Thus, a ramen serving as a leg of the cultivation bed stand of the present invention is obtained. As the pipe, a steel pipe can be used.

Further, the ramen of the present invention can be manufactured by separately manufacturing two grounding portions and three portions of a cross beam portion and a leg portion, and assembling them. Specifically, an L-shaped pipe in which the cross beam portion and the leg portion are U-shaped pipes, and the grounding portion is a swage attached to the grounding portion.
Both are made so that the swage portion can be fitted into the end of the U-shaped pipe. And FIG.
As shown in FIG. 2, the L-shaped pipes are arranged so that the grounding portions 1 and 5 are perpendicular to the plane including the U-shaped pipe and the grounding portions 1 and 5 are symmetrical with respect to the plane. By fitting the U-shaped pipe, a ramen serving as a leg of the cultivation bed frame of the present invention can be obtained. The ramen manufactured in this manner may be referred to as a combination ramen in this specification. In FIG. 3, the direction in which the L-shaped pipe is fitted into the U-shaped pipe is indicated by an arrow.

In order to fix the fitted pipe, as shown in FIG. 8, a horizontal hole 16 is formed in the ground contact portion 1 and the leg portion 2 of the ramen.
And a method of inserting the fixing rod 17 into the lateral hole. In addition, a method of forming a section of the fitting portion 18 of the pipe into an elliptical shape as shown in FIG. 9 or denting a part as shown in FIG. In addition, there is a method in which after fitting an L-shaped pipe and a U-shaped pipe, both are caulked.

In the cultivation bed frame of the present invention, as shown in FIG. 1, the above-mentioned ramen 11 is calculated from the weight of the cultivation bed to be set on the gantry and is installed at necessary intervals. Beam 12 is arranged in the longitudinal direction,
The beam 12 and the cross beam portion 3 of the ramen 11 are fixed by a joint 13 at a portion where they intersect with each other.

When a cultivation bed is placed on a beam, two or more pipes need to be used when a rod-shaped one is used. However, when a plate-shaped one is used, One beam may be used.

By changing the directions of the installation portions 1 and 5 by 180 degrees, two types of planes symmetrical can be obtained. In the manufacture of the gantry, it is preferable to arrange the ramen 11 to be arranged so that adjacent ramen are plane-symmetric as shown in FIG. 1 in order to increase the stability of the gantry.

When the ramen at both ends of the cultivation bed stand are combined ramen, it is possible to direct all the grounding portions toward the inside of the stand as shown in FIG. Also,
Even if it is a ramen manufactured by bending a single pipe, as a ramen at both ends of the cultivation bed stand, the ground contact portion of the ramen is perpendicular to the plane formed by the leg portion and the cross beam portion. And if it uses what was manufactured so that it may turn to the same side with respect to this plane, it is possible to manufacture a cultivation bed stand like Drawing 5.

Further, as shown in FIG. 1, it is preferable to form a set of two adjacent ramen and take a stay 14 below a leg portion of the ramen in order to increase the stability of the gantry. The interval between stays can be extended according to the weight of the cultivation bed. The stays may be braided.
