Then iron pipes 1 of a flank and iron pipes 2 of a roof are coupled by coupling members 10 to form an arch, and a depth-directional iron pipe 3 is inserted into the hole 23 in the key hole shape of the iron plate piece 21 and fixed with the channel shaped wedge 28.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an institutional horticultural house and, more particularly, to a skeleton using a straight iron pipe which is easily available and is easily assembled.

[0002]

2. Description of the Related Art Conventionally, a vinyl house has been used for artificially adjusting cultivation environment conditions such as vegetables, fruit trees, and flowers to create an environment different from outdoor cultivation, improving productivity and high profitability. There is.

In a conventional vinyl house, as shown in FIG. 7, a pair of curved iron pipes 4 are opposed to each other, and the rear ends of the iron pipes are inserted into the ground to insert a pair of iron pipes 4 into the ground. An arch is formed by abutting and joining the tips 5 together. A large number of arches are arranged in the depth direction to form a skeleton, and vinyl is attached.

[0004]

In such a conventional vinyl house, it is difficult to bend the iron pipe in the field when forming the arch-shaped aggregate, and therefore, it is difficult to bend the iron pipe in the factory beforehand. The pipes are bent and transported to the site to form a framework.

In addition, a long seamless steel pipe bent in an arch shape cannot be carried unless a large vehicle is used, and the load capacity of the bent pipe is smaller than that of a straight pipe. A lot of cost and labor was required for transportation and unloading.

[0006] Further, long iron pipes have a long delivery time because they are made to order, and a supplier supplying a framework of a vinyl house must always keep a certain amount of them in stock.

Therefore, the present invention has been conceived in order to solve such a problem, and an arch is formed by connecting linear iron pipes without bending the iron pipes, and each arch is formed. Are connected to form a frame of a house.

[0008]

In the greenhouse for greenhouses of the present invention, the double pipe 11 is provided at the center of the double pipe 11 in which a long and thin iron pipe 13 is inserted into a short and thick pipe 12. A connecting member 10 bent while forming a groove-shaped recess 14 parallel to the inside and an iron plate piece having an arc 27 formed on the top of a pentagon.
21 with a round hole 24 and a channel wedge 28 in the center
An iron plate piece 21 having a keyhole-shaped hole 23 composed of a groove 25 for driving a hole and two small holes 26 through which a screw for fixing a band formed at a position symmetrical to this keyhole-shaped hole 23 is inserted; A connecting member 20 including a band 30 for fixing 21 and a wedge 28 for fixing the pipe 3 to the iron plate piece 21 is provided, and the iron pipe 1 on the side surface and the iron pipe 2 for the roof are provided by the connecting member 10.
To form an arch, and the keyhole-shaped hole of the iron plate piece 21
The iron pipe 3 in the depth direction is inserted through 23 and fixed by a channel-shaped wedge 28.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION
As shown in FIG. 1, two linear iron pipes 1 forming both side surfaces of the arch, two linear iron pipes 2 forming the roof of the arch, and each of these linear iron pipes. 1
It is composed of three connecting members 10 which are connected at an angle of 20 °.

As shown in FIG. 2 (a), each connecting member 10 has a double pipe 11 in which a long and thin iron pipe 13 is inserted into a short and thick iron pipe (sleeve) 12 at 120 °. It is bent at an angle of.

When the connecting member 10 is made, the double pipe 11 is housed in a parallel form having a distance substantially equal to the outer diameter of the thick iron pipe 12, and the central portion of the double pipe 11 has a roundness. Press the plate-shaped mold and the groove-shaped recess parallel to the double pipe 11.
While forming 14, the double pipe 11 is bent at an angle of 120 ° with the groove-shaped recess 14 inside. The cross-sectional shape of each portion of the coupling member 10 thus manufactured is shown in FIG.
It is as shown in (b).

When the four linear iron pipes 1 and 2 are joined by this joining member 10 to form an arch, thin iron pipes 13 projecting from both ends of the joining member 10 are used.
And it is connected by inserting it into the iron pipe 2.

A large number of arches made up of the iron pipe 1 and the iron pipe 2 joined by the joining member 10 are arranged in the depth direction with a constant interval, and the arches are connected by the pipe 3 in the depth direction to form a framework. To do. At this time, the connecting member 20 is used to connect the connecting member 10 and the pipe 3.

As shown in the perspective view of FIG. 3, the connecting member 20 includes an iron plate piece 21 having a pentagonal top portion with an arc 27, a band 30 for fixing the iron plate piece 21 to the coupling member 10, and a pipe 3 for the iron plate. It is constituted by a wedge 28 fixed to the piece 21.

As shown in the perspective view of FIG. 4, the iron plate piece 21 is
The angle of the top side 22 is 120 °, the arc 27 is formed at the top, and the keyhole-shaped hole 23 has a round hole 24 and a groove 25 into which a channel-shaped wedge 28 is driven in the central part, and this keyhole. There are two small holes 26, which are formed at symmetrical positions with respect to the shaped holes 23 and through which screws for fixing the band are inserted. A round hole
A small hole 29 formed in the center adjacent to 24 is a hole used for connecting other members such as columns and beams. In addition,
When punching the round hole 24, if the punch is not punched by the press die and the hole is pushed by the die, as shown in the cross-sectional view of FIG. 5, a ridge 24a is formed around the round hole 24 and the iron plate piece 21 The strength of the round hole 24 can be increased.

Next, a procedure for assembling the framework of the house by combining the iron pipes 1 to 3 with the connecting member 10 and the connecting member 20 thus constructed will be described.

After fitting the arcuate portion 27 of the top side 22 of the iron plate piece 21 into the groove-shaped recess 14 of the coupling member 10, the two bands 30 are fixed by the bolts 31 and the nuts 32.

After the joining member 10 and the iron plate piece 21 are combined in this way, the thin iron pipes 13 projecting from both ends of the joining member 10 are inserted into the iron pipes 1 and 2 to join them. , Form arches at equal intervals in the depth direction.

In this connection, if the length of the thin iron pipe 13 of the connecting member 10 is more than a certain length (15 cm), a frictional force is generated by the gravity of the two iron pipes 2 forming the arch roof. The iron pipe 13 of the connecting member 10 is simply inserted into the iron pipe 1 or the iron pipe 2 and does not come out.

Next, as shown in FIG. 6, the pipe 3 is inserted into the round holes 24 of each iron plate piece 21 of each arch arranged at equal intervals in the depth direction, and the channel is inserted into the groove 25 of the keyhole-shaped hole 23. Wedge
The frame of the house is completed by driving 28 and fixing the iron plate piece 21 and the pipe 3.

(Other Embodiments of the Invention) In the embodiment described above, the bending angle of the coupling member 10 is 1 or less.
Although it is 20 °, it is set to an arbitrary angle so that the total bending angle of the three connecting members 10 becomes 360 °, and the length of each iron pipe is appropriately determined to match the type of plant to be cultivated. You can make a house of different height and shape.

[0022]

As is apparent from the description based on the above-described embodiments, according to the greenhouse gardening house of the present invention, the straight pipes are assembled by using the joining member 10 that is pre-bent. Therefore, the bending process of the pipe is unnecessary and the assembling is easy, so that the labor and cost required for the construction can be reduced.

In addition, since the facility gardening house of the present invention has vertical side surfaces and the side walls are not bent unlike the conventional vinyl house, the internal space can be effectively utilized.
