DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greenhouse having a pipe structure suitable for agricultural and horticultural use.

[0002]

2. Description of the Related Art Greenhouses used in agriculture, horticulture and the like have a steel structure and a pipe structure. Since the steel structure can be made a robust structure,
It has the advantage of being able to withstand typhoons and the like, but the high construction cost has become a bottleneck and has not yet spread.

[0003] On the other hand, the pipe structure has an advantage that the construction cost is low, but the disadvantage that the structure is weak and cannot withstand a typhoon cannot be avoided.

In a steel structure, a ventilation window is generally provided on the ridge side. However, in the case of a pipe structure, it is difficult to provide a ventilation window, and when a ventilation window is provided, the structure becomes complicated. Therefore, the construction cost increases accordingly.

The technical problem of the present invention is to pay attention to such a problem, and to make it possible to form a ventilation window with a robust structure and at a low cost in a pipe type house whose construction cost is low.

[0006]

The technical problem of the present invention is solved by the following means. Claim 1 is a structure of a framework before assembling into a house, and has a structure in which each arch set is divided into two at a ridge so as to form an arched pipe set. The connecting pipe is welded and fixed to each of the divided arch sets so that the connecting pipe in the ridge direction can be inserted in a state where each arch set is erected. Further, a fastening bolt can be screwed into the connecting pipe so that the connecting pipe inserted into the connecting pipe can be tightened and fixed.

As described above, since each arch set is divided into two at the ridge so that an arch-shaped pipe set can be formed, it is necessary to transport the pipe set before assembling the arch-shaped house. The construction is easy because the arched house can be assembled simply by connecting the ridges on site.

[0008] Since the ridge direction can be firmly assembled simply by inserting the connecting pipe into the connecting pipe welded and fixed to each arch set and tightening the bolt, the short connecting pipe is transported, and the connecting pipe is used on site. A house can be realized just by connecting.

A second aspect of the present invention relates to a structure of a house assembled by using the pipe set according to the first aspect, wherein an arch set of a pipe structure which is preliminarily divided into two at the ridge and connected at the ridge. Stand at predetermined intervals, insert the connecting pipe in the direction parallel to the ridge through the connecting pipe welded and fixed to each arch set,
The connection pipe is fastened and fixed by bolts screwed into the connection pipe.

As described above, in the house assembled by using the pipe set according to the first aspect, an arch set having a pipe structure in which the arch set divided in advance at the ridge portion is connected at the ridge portion at a predetermined interval. With a structure in which the connecting pipe is inserted and bolted to the connecting pipe welded and fixed to each arch set, a house with high strength in the ridge direction can be realized. The strength in the vertical and horizontal directions can be easily realized by using a double arch structure reinforced with lattices as shown in the figure.

A third aspect of the present invention is a frame structure before assembling into a house, wherein each arch set is divided into two at a ridge so as to form an arched pipe set. The pipe assembly structure is characterized in that a pair of split arches have different lengths of legs in advance so that the two divided arch assemblies can be connected in the ridge portion in a vertically shifted manner.

As described above, the length of the legs of the pair of divided arch sets is previously made different so that the arch set divided into two at the ridge part can be vertically shifted and connected at the ridge part. When assembled, the ventilation window can be easily realized simply by shifting the left and right divided arch sets in the ridge part up and down. In addition, since a split arch set having a symmetrical structure is used, and only one extension leg is added to one side, it can be manufactured at low cost.

A fourth aspect of the present invention is a pipe type in which an arch set previously divided into two at the ridge is vertically shifted at the ridge and connected to each other, and a ventilation window is provided between the upper ridge and the lower ridge. House.

As described above, the arch assembly previously divided into two at the ridge portion is vertically shifted at the ridge portion and connected to form a ventilation window between the upper ridge portion and the lower ridge portion. Although it is a house, a ventilation window can be easily and inexpensively realized, and an abnormal temperature rise in the house can be prevented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a pipe-type house and a pipe assembly according to the present invention. FIG. 1 is a perspective view showing an embodiment of a pipe type house according to the present invention.

Reference numeral 1 denotes an arched pipe set, and a pair of left and right divided arch sets 1a and 1b are connected by a ridge 2. A plurality of such arched pipe sets 1 are assembled at a constant interval D. Each arched pipe set 1 shown in the drawing has a double structure in which an outer pipe 3 and an inner pipe 4 are connected by a zigzag lattice streak 5.

In each of the arched pipe sets 1, both ends where an entrance and the like are provided are erected by embedding feet on a concrete foundation 6, whereas the other ends are concrete blocks 7 embedded in a pile shape. The foot is buried in it.

A connecting pipe 8 is welded and fixed to each arched pipe set 1 in a ridge direction (a direction parallel to the ridge). And
The connecting pipe 9 is inserted into the connecting pipe 8 and is fixed by bolting.

At the end, a required number of support pipes 10 are provided.
A horizontal pipe 11 is welded and fixed, and a door 12 is provided.

FIG. 2 is a side view of a pair of divided arch sets 1a and 1b, and FIG. 3 is an enlarged perspective view of a main part thereof. The pair of left and right divided arch sets 1a and 1b has a symmetric structure.

In the ridge portion of the pair of divided arch sets 1a and 1b, as shown in FIG. 3A, the tip of the outer pipe 3 and the tip of the inner pipe 4 are connected to the vertical angle members 13a and 13b.
It is fixed by welding to the inner surface.

Then, each of the angle members 13a, 1
3b, two holes 14a and 14b for inserting bolts are formed in two upper and lower positions, so that the corresponding bolt holes 14a and 14b are formed.
The bolts are inserted and fastened to form an arched pipe set 1 as shown in FIG.

In the ridge part, a connecting pipe 8a is horizontally welded and fixed to the tip of the inner pipe 4 of one of the divided arch sets 1a so that the connecting pipe 9 can be inserted at two upper and lower locations, and the other divided part is assembled. A connecting pipe 8b is attached to the tip of the outer pipe 3 of the arch set 1b.
Is fixed horizontally by welding.

The distance between the outer pipe 3 and the inner pipe 4 is
The ridge side is the widest and gradually narrows toward the feet.
Then, as shown in FIG. 3 (2), two pipes 3
1, 41 are fixed to the inner surface of the angle member 15 by welding.

The angle member 15 may be directly buried in a concrete foundation or the like and a leg may be erected. However, a bolt hole 16 is formed, and a bolt hole 16 is formed in a buried member previously buried in the concrete foundation or the like. Using
You may connect with a bolt. In addition, the hem connecting pipe 8c is fixed to the toe pipe 31 by welding.

Alternatively, as shown in FIG.
It is also possible to insert the pipes 31 and 41 into the pipe 15a and weld and integrate them, insert the pipe 15a into the pipe pile 15b previously driven into the field, and tighten and fix it with the bolt B4. it can. This bolt B
4 is exactly the same as that of FIG.

FIG. 4 is an enlarged sectional view of the connecting pipe. FIG.
The connecting pipe 8 of (1) is short, and one connecting pipe 9 is inserted therethrough, whereas the connecting pipe 8L of FIG. 4 (2) is long, and separate connecting pipe ends 91, 92 are inserted at both ends. ing.

That is, since the long connecting pipe 8L of FIG. 4B is fixed by welding to the connecting portion between the connecting pipe ends 91 and 92, separate connecting pipe ends 91 and 92 are inserted from both sides. The connection pipe ends 91 and 92 can be connected by tightening and fixing the bolts B1 and B1.

On the other hand, in the portion that does not require connection, FIG.
Since the short connecting pipe 8 is fixed by welding as in (1),
The connecting pipe 9 is inserted into the inside, and is fastened and fixed with one bolt B1.

In order to tighten the internal connecting pipe 9 and the connecting pipe ends 91 and 92 at the ends of the bolts B1, a hole 18 through which the ends of the bolts can enter and exit the connecting pipes 8 and 8L is formed. 19 are overlapped and fixed by welding. Therefore, when the connecting pipe 9 and the connecting pipe ends 91 and 92 are inserted into the connecting pipes 8 and 8L and the bolts B1 are tightened, the connecting pipe 9 and the connecting pipe ends 91 and 92 are fixed to the connecting pipes 8 and 8L.

As described above, the arched pipe sets 1 are connected to each other by the connecting pipes 9 inserted into the connecting pipes 8 and 8L and fixed by bolts, so that the strength in the ridge direction is reduced. It can be sufficiently held by the pipe 9. The connecting pipe 9 is suitably made of metal, but may be made of rebar.

As for the strength in the vertical direction and the horizontal direction (perpendicular to the ridge), the arched pipe set 1 has a double-arch structure with the inner and outer pipes 3 and 4, with a zigzag lattice stitch between the two. Since they are connected with each other, sufficient strength can be maintained. Since the lattice bar 5 is formed by bending a single reinforcing bar in a zigzag shape in advance, it is easy to assemble the inner and outer pipes 3 and 4 by welding.

It goes without saying that, in the pipe assembly structure as shown in FIG. 1, a vinyl or net is put on the pipe assembly structure and fixed by a component called a vinylet (trademark). It should be noted that a roof member such as a tin can be used instead of vinyl.

In order to prevent the temperature inside the greenhouse from rising abnormally, it is necessary to wind up the vinyl on the side of the greenhouse or open a ventilation window on the ceiling. However, in the structure as shown in FIG. 1, it is difficult to open the ventilation window on the ceiling.

FIG. 5 solves this problem. The divided arch set 1b on the right side of the divided arch set 1a on the left side of FIG.
Of the foot 15b is increased, for example, by about 20 cm. As a result, the roof part is higher by about 20 cm on the right side divided arch set 1b side than the left divided arch set 1a in the figure.

Therefore, the vertical angle members 13a and 13b of the ridge are connected to the lower left angle material 1
The upper end of 3a and the middle of the right higher angle member 13b are connected by a bolt B2, and the middle of the lower left angle member 13a and the lower end of the right higher angle member 13b are connected to a bolt B3.
Are connected with each other.

In this way, if the ridge is shifted up and down by the height H and only this portion is opened with vinyl,
Since the hot air inside escapes to the outside, it can serve the same function as the ventilation window of the conventional steel structure house. Moreover, since it is sufficient to simply move the connecting portion of the ridge up and down, the structure and construction are extremely simple and can be realized at low cost.

In the example described above, the legs 15b of the right divided arch set 1b are lengthened in order to shift the ridge part up and down. However, if the terrain has a step, the divided arch set 1a having the same size is used.
1b is also possible. Alternatively, it is also possible to raise the height in advance using a concrete foundation or a pile-like foundation only on one side, and to raise the one divided arch set 1b thereon.

As shown by the chain line in FIG. 3 (1), holes for connecting bolts are also formed in the middle, and are provided at equal intervals at the upper, lower, and middle positions. Can be selected. In addition, although the angle members 13a and 13b are illustrated, a flat plate may be used, or an angle member may be interposed for reinforcement in the middle.

[0040]

According to the first aspect of the present invention, each arch set is divided into two at the ridge so that an arched pipe set can be formed. Therefore, the pipe set before assembling the arched house is constructed. Because it is easy to transport and you can assemble an arched house just by connecting the ridges on site,
Construction is also easy.

Then, the ridge direction can be firmly assembled only by inserting the connecting pipe into the connecting pipe welded and fixed to each arch set and tightening with bolts. Therefore, the short connecting pipe is transported, and the connecting pipe is used on site. A house can be realized just by connecting.

According to a second aspect of the present invention, a house assembled by using the pipe set according to the first aspect has an arch set of a pipe structure in which an arch set previously divided into two at the ridge part is connected at the ridge part. With a structure in which the connecting pipes are inserted into the connecting pipes welded and fixed to the respective arch sets and bolted at predetermined intervals, a house with high strength in the ridge direction can be realized.

According to the third aspect, the arch set divided into two at the ridge portion can be vertically shifted and connected at the ridge portion.
Since the lengths of the legs of the pair of divided arch sets are different in advance, when assembled on site, the ventilation window can be easily realized only by shifting the left and right divided arch sets in the ridge part up and down. In addition, since a split arch set having a symmetrical structure is used, and only one extension leg is added to one side, it can be manufactured at low cost.

According to the fourth aspect, the arch assembly previously divided into two at the ridge portion is vertically shifted at the ridge portion and connected to form a ventilation window between the upper ridge portion and the lower ridge portion. Although it is a house having a structure, a ventilation window can be easily and inexpensively realized, and an abnormal temperature rise in the house can be prevented.
