DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure such as a large plastic greenhouse constructed by using a concrete electric pole and its joint fitting.

[0002]

2. Description of the Related Art Recently, concrete poles have been used exclusively for concrete. However, since the poles are as long as about 6 meters or more, used concrete poles that have been removed can be used for other purposes. At present, they are crushed and disposed of without being reused.

On the other hand, in recent years, cultivation using a greenhouse or a greenhouse has been frequently performed in order to produce horticultural crops having high added value. However, since the conventional greenhouse has a simple structure using an iron pipe or a vinyl chloride pipe as a structural material, the strength is weak, and it is difficult to construct a large greenhouse with a high roof. On the other hand, construction costs are high, and they are easily damaged by typhoons or the like. Attempts have been made to grow mangos and other tropical fruit trees in plastic greenhouses in order to produce higher value-added crops. Therefore, a greenhouse structure having a higher height and a larger area is required. A greenhouse with a large roof and large area can be made by using a steel frame structure, etc., but there are various inconveniences, such as high construction costs, long-term construction, and large-scale foundation work in the field. . Therefore, conventionally, tall tropical plants have been suitable for cultivation only in permanent buildings such as greenhouses. Also,
Conventionally, in the case of a structure having a relatively high roof and requiring a large area, such as a warehouse or an exhibition hall, there has been no steel structure, a concrete structure, or the like, which has a high construction cost and can be easily constructed at a low cost.

[0004]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a part of a structure using a concrete electric pole as a pillar according to an embodiment of the present invention.
FIG. 6 is a top view as seen from the direction of arrows BB in the column arrangement diagram shown in FIG. First,
Before describing the overall configuration of the structure, a description will be given of a joint fitting and a beam that are fitted to the top of a concrete utility pole used in the present structure and that connect a beam or the like. FIG. 2 shows a joint fitting. The joint fitting 1 has an inside diameter capable of freely fitting to the top of a concrete electric pole, and has an appropriate length with the top 3 closed and the lower end open, in this embodiment about 50 c.
It has a joint bracket body 2 made of iron pipe of about m, along its outer circumference direction, are constructed by welding the radiating shape of the connecting flange 5 of the beam, such as in a predetermined direction. The connection flange 5 has a plurality of holes 6 for connecting beams and the like with a bottle. The joint fitting body 2
In order to prevent the concrete pole from being pulled out from the state covered with the concrete pole, a hole 4 for engaging a fastener such as a bolt screw hole or a hook is formed, and a scaffold provided on the concrete pole is provided. Connect and fix the bolt with a turnbuckle or the like. However, the provision of the locking hole is provided when there is a risk of separation during a typhoon or the like, and is not necessarily provided. The radial direction and number of the connection flanges 5 of the joint fitting 1 differ depending on the position where the concrete utility pole is erected, and the one shown in FIG. 2 needs to connect the beams except in the side wall direction as shown in FIG. A joint fitting 1a covered by a concrete utility pole 11a erected at a position 10a where there is no mark is shown.
In the structure of the present embodiment, in addition to the joint fittings shown in FIG. 2, those shown in FIG. 3 are used.

In FIG. 3, for convenience of description, the same parts as those in FIG. 2 are denoted by the same reference numerals. The one shown in FIG.
It is a joint fitting 1b covered by a concrete utility pole 11b erected on a corner 10b, and two connection flanges 5 are arranged at right angles. Also, what is shown in (b) is a joint fitting 1c covered by a concrete electric pole 11c erected at a position 10c where beams need to be connected in three directions, and two joints arranged at 180 ° intervals Another connecting flange 5 is disposed at a right angle between the connecting flanges 5. Further, the one shown in (c) is a joint fitting 1d for covering a concrete electric pole 11d erected at an internal position 10d of a structure in which beams need to be connected in four directions, and four connecting flanges are provided. They are arranged at right angles to each other. However, it is needless to say that the number and the direction of the connection flanges are not limited to these, and can be arbitrarily selected as needed.

FIG. 4 shows an embodiment of a beam used in this embodiment. The beam 15 is composed of two upper and lower iron pipes 16,
A connecting plate 18 overlapping with the connection flange of the joint fitting is fixed to both ends of the joint 17 by welding, and a middle portion of the upper and lower iron pipes is formed by appropriately arranging round bars 19 and the like. The connection plate 18 is formed with a round hole 20 or a long hole at the same pitch as the holes 6 formed in the connection flange.

Using the above members, for example, 50,000 × 66,000 as shown in the column arrangement diagram of FIG.
Next, an example of a construction method for building a large-sized greenhouse structure having a plane rectangular shape of mm (3,300 m ² ) will be described.
First, a hole in which a concrete electric pole can be erected is excavated with an auger or the like at the four corner positions 10b of the greenhouse in the field, and the concrete electric pole 11b is erected. At this time, if the concrete poles are not properly centered, a large error occurs in the top space between the concrete poles 11. As the centering method, point surveying is effective, but the cost is high. Therefore, in this embodiment, the farmland plane matching method is adopted.
That is, first, a mark of the height is put on the concrete electric pole 11b at the four corners, the concrete electric pole 11b is erected, a thread is drawn on the mark, a point is pressed from the thread, and the pillar is centered by the thread, Simple and effective centering was achieved. In the case where a concrete pole with a short length is required for standing on an inclined surface or the like on an inclined surface or the like, it is not necessary to drill a deep hole by appropriately cutting the base of the concrete pole.

When the concrete utility pole 11b is erected in a square centered on the center, based on this, in the present embodiment, along the peripheral wall (the left ends of the front and rear walls are 6m apart) at intervals of 5m,
Holes are excavated and concrete utility poles 11a and 11b are sequentially erected. Next, the concrete utility pole 11d is erected on the basis of the concrete utility pole erected on the peripheral wall while centering at an interval of 10 meters along the left-right direction and at an interval of 5m along the front-rear direction. . Before or after the concrete pole, the above-mentioned joint fitting is crowned on the top, but the joint pole 1b is attached to the concrete pole 11b standing upright, and the concrete pole 11a standing upright on the peripheral wall. , 11c has joint fittings
1a, 1c is installed inside a concrete telephone pole 11
d is covered with a joint fitting 1d .

The connecting plate 18 of the beam 15 is fixed between the connecting flanges of the concrete utility poles 11 by bolts 21 so that the concrete utility poles 11 are connected.
Are connected by beams 15. In addition, as shown in the figure, the bolt holes 12 for the scaffold bolts of the concrete utility pole are used to attach the windproof net 25 or the vinyl sheet as the outer wall to the concrete utility pole erected on the peripheral wall portion.
A wall body fixing rod 22 made of a C-shaped angle material is fixed along the axial direction. Then, a wall body edge 23 made of a C-shaped angle material is fixed to the wall body edge fixing rod 22 at appropriate intervals. Further, a holding device 24 which is a member for attaching a windproof net is fixed to the wall body edge 23 in the vertical direction. By attaching the windproof net 25 or the vinyl sheet to the holding device 24, the peripheral wall is easily configured.

In the case of a conventional greenhouse, the windproof net 25 or the vinyl sheet is stretched by first raising the net on the roof, fixing the upper edge of the net along the upper end of the side wall, and then lowering the net along the wall. It is stuck and fixed to the holding device fixed in the vertical direction at appropriate intervals. Therefore, in the conventional method, the operator has to repeatedly move up and down along the clamp. However, if this method is adopted in the present invention having a high roof structure, it is difficult to raise the windbreak net to a high place, and it is dangerous to mount the windproof net at a high place. Alternatively, the ascent and descent of the ground and the roof must be repeated, which is very inefficient. Therefore, in the present embodiment, the following method is employed instead of the conventional method.

First, the windproof net 25 is spread on the ground along the wall, and is wound in a roll shape so that the front and rear or the left and right directions of the house become the axis. Next, the rope is lowered at appropriate intervals from the roof, and the rolled windproof net 25 is tied up.
When the upper and lower walls are 50 meters or more in length as in the above embodiment, for example, the upper end is first fixed to the holding tool 24 by fitting a spring to only half the length. Further, as shown in the figure, the roof is provided with bridges 26 made of pipes at appropriate intervals in the front-rear direction over the beams, and fixed with appropriate fittings. A rafter 27 made of a pipe is laid over the girder 26 at an appropriate interval, and fixed with metal fittings, thereby forming a grid-like roof assembly. A vinyl sheet 28 is provided on the upper surface to form a flat roof. Is done. FIGS. 6 and 7 show perspective views of the greenhouse constructed as described above.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various design changes can be made.
For example, in the above-described embodiment, the flat roof structure has been described. However, the structure of the roof is not limited to the above-described embodiment, and it is needless to say that a gable roof, a Kamaboko roof, a saw-shaped roof, a ridge, and the like can be appropriately used. Nor. In addition, it is of course possible to form a continuous building. 8 and 9 show an embodiment in the case of a kneading-type building. In this embodiment, a gabled roof was formed, only the outer wall portion of the ridge was supported by a concrete utility pole 11, and the beams were directly connected to each other at the middle portion of the ridge by beam connection fittings. FIG. 9A shows a schematic cross section of a ridge located on the outer wall. Joint fitting 2 used at this position
Reference numeral 9 denotes a cylindrical joint fitting main body 30 having an inner peripheral wall fitted to the top of the concrete utility pole, and a connection projecting from the outer peripheral surface of the main body to both sides in the wall direction and having upper and lower edges inclined to match the slope of the roof. And a ridgeboard receiving bracket 34 having a U-shaped cross section provided on the top thereof, and these are welded and integrated. The connection flange 32
The roof can be easily assembled by connecting the kneading plates 33 of the beams 31 with bolts, fitting the purlin 35 to the purlin receiving brackets 34, and fixing them with appropriate bolts (not shown). The middle part of the upper part of the building is shown in Fig. 9.
As shown in (b) , the connection plate 38 welded to the end of the intermediate beam 37 is bolted to the beam connection fitting 39 formed by welding two key-shaped iron plates, and the upper part of the beam connection fitting 39 is formed. Can be assembled by fitting the purlin 35 to the purlin receiving part 36 formed in the above and fixing it with bolts or the like. The purlin,
Although square wood may be used, a metal or plastic square pipe is preferable. In addition, in FIG. 8, 40 is a rain gutter,
41 indicates an entrance.

In each of the above embodiments, the concrete poles are connected only by beams at the upper part.
By providing braces between concrete utility poles, a stronger structure can be obtained. Although the above embodiment has been described with reference to a greenhouse, the present invention is not limited to a greenhouse, and a wall or a roof may be made of a normal wall material or a roof material such as a panel which does not transmit light. It is possible to construct a high-roof structure with a wide area that is optimal for buildings and exhibition halls. Further, in the above-described embodiment, the joint fitting was fitted to the top of the concrete utility pole.However, the joint fitting was formed into a cylindrical shape with an open top and bottom, and a connection flange was provided on the outer periphery in the same manner as in the above-described embodiment. With this configuration, the concrete pole can be fixed to the middle part of the concrete pole using scaffolding bolts of the pole. As a result, floors and ceilings can be constructed, and multi-story structures can be easily and inexpensively obtained.
