Description

The present invention relates to a framework structure of a simple building such as a greenhouse, a cherry house, a livestock barn, and an insect-proof house for outdoor vegetables.

Conventionally, for the purpose of obtaining a house that is simple and strong in frame structure, prevents deformation due to the weight of the covering body of the sheet or the like and the frame body and makes the shape perfect, and can be enlarged in size, as shown in FIG.
A frame 51 made of a plurality of PC steel wires shown in a) to (e) is bent in an arc shape, and both outer ends thereof are inserted into the ground and appropriately connected to form a framework to form a vinyl or other sheet or film. In the agricultural or horticultural house, the frame body 51 is alternately inclined in the opposite direction and inserted into the ground, and at least the crossing portion of each frame body is connected by a slant metal or metal fittings 54, 55, etc. An agricultural or horticultural house has been proposed in which each frame 51 is tightened and tightened in a direction in which the frame 51 is bent by a tightening member 53.

On the other hand, in the conventional agricultural house, a plurality of arch-shaped curved members 61 are mounted in parallel to the left and right foundations 62 at intervals, and the plurality of arch-shaped curved members are connected by braces and tie bars. After composing the body, the surface of the frame body was covered with a covering film, so in the conventional framework, it is not possible to increase or decrease between beams and increase or decrease column pitch with the same material. Depending on the size of the agricultural house, it is necessary to prepare arch-shaped curved materials as well as braces and tie bars of different sizes, which not only increases the production cost but also takes a lot of time to assemble. In order to improve the disadvantages such as weakening in strength, the connecting brackets 67a and 67b shown in FIG. Proximal side Four bent members 61 of the same member, which are respectively mounted, are attached to each other in a crossed manner, and the attached portions of the bent members 61 are connected to each other in a crossed manner so that they can be rotated around a pivot shaft. Crossed arch frame A formed by sequentially connecting tools 67a and 67b
A cross-type arch type agricultural house is proposed in which a plurality of sets are adjacent to each other and a covering film is covered with an auxiliary member on the surface of the cross-type arch frame A that is continuously formed.
Japanese Unexamined Patent Publication No. 57-181621

The invention described in Patent Document 1 will be outlined with reference to FIG.
A frame 51 made of a plurality of PC steel wires is bent in an arc shape, and both outer ends thereof are inserted into the ground,
It is only described that the frame 51 is alternately crossed and the crossing portion is appropriately connected by the metal fittings 54, 55, etc. to constitute a frame. This frame is described with reference to FIGS. 9 (a) and 9 (b). However, it does not have a skeleton member. Therefore, this frame cannot transmit the stress to other frames through the building members in the ridge direction and cannot disperse the load. Therefore, it is necessary to increase the rigidity of the frame itself, which increases the cost. It becomes. Furthermore, as shown in (d) and (e) of FIG. 9, the PC steel wire of the frame 51 is joined at the site of the X-shaped coupling metal 55, and is itself non-continuous. Moreover, since the hole 56 for penetrating the tightening member 53 is formed in the X-shaped connecting metal 55, the load on the agricultural house is concentrated on the part of the connecting metal 55 due to the structural stress. It can be a weak point, and the rigidity cannot be so high for the expensive PC steel wire.

On the other hand, since the invention described in Patent Document 2 requires a concrete foundation to be laid as shown in FIG. 10 (d), the construction period becomes longer and causes an increase in cost. Moreover, since the pipe diameter used as a frame material is not different from the conventional one, it is impossible to reduce the total amount of pipe material used.
Furthermore, since there are no ridge-direction members at the intersection of the cross-type arch frame, the strength against the load in the ridge direction is not particularly high, and the fluttering of the covering film is large when wind blows, and the strength of the covering film is degraded. When rainwater accumulates on the ceiling of the house, it requires work to push up the covering film from the house and drain it, and maintenance is not easy.

In view of the above situation, the present invention has an object to overcome the disadvantages of the prior art, and by making the framework structure of a simple building a very unique structure, it is made of carbon steel that has been conventionally used as the framework of a simple building. While reducing the total amount of pipe material used on a weight basis, and eliminating the foundation work itself and simplifying assembly work, significantly reducing construction costs,
The object is to provide a high-strength simple building framework.

3 is fixed.

As is clear from the above description, according to the framework structure of the simple building of this embodiment, in the ridge, four steel pipe pipes are integrated by the X-shaped connecting pipe 16 to constitute the framework unit 3;
The frame unit 3 is fixed to the purlin 5 with a semicircular curved plate 13 and a pedestal 14, and the arch members of adjacent frame units are joined to each other at an intermediate portion between the purlin 5 and the girder 6 with an X-shaped joint 21. The arch members of the frame units 3 that are adjacent to each other in the shoulder portion are brought close to each other and joined to the beam member 6 to constitute the roof surface.
Between the purlin 5 and the girder 6 on the roof surface, a truss having the purlin 5 as the upper chord material and the girder 6 as the lower chord material is doubled, and a frame with excellent strength is constructed. be able to.

The frame structure of the present invention is a steel pipe pipe with a diameter of 22.2 mm, a building with a frontage of 5.4 m and a span of 0.9 m of the frame unit, and a conventional steel pipe pipe with a diameter of 25.4 mm, The results of a comparative test of frame structures constructed with a frontage of 5.4 m and a span of 0.45 m and spaced in parallel to the purlin direction are shown below.
《Horizontal tensile test》
In this test, a tensile load was applied in the direction of the ridge, and the moving distance of the wife arch material was measured. The results are shown in Table 1.

<< Vertical tensile test >>
In this test, vertical distance was applied to measure the descending distance of purlin and arch. The results are shown in Table 2.
According to this test result, the strength in the ridge direction is about 6 times with a tensile load of 30 kg compared to the conventional type despite the fact that the framework structure of the present invention is constructed from a smaller diameter than the conventional type. It can be seen that the strength in the vertical direction is about 4 times with a load of 65 kg.

As described above, the amount of use of the arch material is that the frame structure of the present invention has a span set to about twice that of the conventional type, so that the frame unit is composed of members arranged diagonally, Although the length of use is slightly increased, the diameter of the steel pipe used can be reduced, and the weight used can be reduced by about 40 to 50%. Therefore, the strength is extremely high while reducing the construction cost of a simple building. Can be built.

As described above, the single building has been described as an example. However, in the case of a continuous building, as shown in FIG. 8, the arch members 2a and 2b, 3a and 3d, and 3c and 3b having adjacent frame structures are brought close to or intersecting with each other. What is necessary is just to install the trough 9 in the shoulder part of a mutual house where the arch material adjoins. The covering material is spread on the surface other than the lower part of the trough 9.
