Description

[Detailed description of the invention] Industrial field of application The present invention relates to various types of houses such as pipe houses and vinyl houses, for example, by molding the roof with plastic film so that air can be freely taken in and out, and in addition, the whole or part of the roof is made of plastic film. The roof is made of a plastic film that is not breathable but is water-wicking, and the roof is sloped laterally in the width direction.

Prior Art There are various types of houses such as pipe houses and vinyl houses. As an example, the one shown in Figure 1A is a single-building type, and the one shown in Figure 1B is a multi-building type. In both of these, struts a arranged at appropriate intervals in the front and rear direction are connected by front and rear connecting members b, and a semicircular support member c is placed between adjacent front and rear connecting members b.
is constructed, and a vinyl sheet d is placed on top of this support material c.
It is covered with a roof to form a roof.

Therefore, this agricultural greenhouse necessarily requires supporting materials c, which makes assembly troublesome, and requires many supporting materials, which increases the material cost.

In order to solve this difficulty, the applicant has shown in Figure 2,
We developed a house as shown in Figure 3. In this method, struts 1 erected at appropriate intervals in the front and rear direction are connected in the front and rear direction by front and rear connecting members 2, horizontally adjacent struts 1 are connected by horizontal connecting members 3, and further between adjacent front and rear connecting members 2. A plastic film roof 4 through which air can be taken in and out is provided.

However, this is a plastic film roof4.
There was a problem in that the moisture in the air that was introduced into the roof 4 liquefied and accumulated in the lower central part 5 of the roof 4, causing the lower part to sag due to the weight of the water.

In order to further solve this problem, the applicant has developed a roof 4 in which all or part of the roof 4 is made of a plastic film (for example, polyvinyl alcohol film: PVA) that is not breathable but has water absorption properties.

Problems to be solved by this invention However, in this case, if a non-breathable but water-absorbing plastic film is installed in the lower central part 5 of the roof, where water tends to accumulate, as shown in Figure 4, the water that accumulates there will be removed. There was a problem in that the water turned into water droplets and fell onto the fields below, hitting the vegetables grown in the fields and damaging them.

Means for Solving the Problems The purpose of the present invention is to solve the above problems.

Therefore, as shown in FIG. 6, the present invention has a plastic film roof 4 that allows air to be freely taken in and out, and is sloped laterally in the width direction, and the entire roof or at least the lowermost part 15 of the roof is ventilated. It is molded from a plastic film that is water-absorbent but has no water-absorbing properties.

Embodiment In Figures 2 and below, 1 is a support column, 2 is a front and rear connecting member, 3 is a horizontal connecting member, and 4 is a roof. Among these, as the pillars 1 and the horizontal connecting members 3, round pipes are used as in conventional agricultural greenhouses.

The front and rear connecting members 2 are round pipes 6 as shown in FIG.
and roof mounting material 7 may be used in combination, or only roof mounting material 7 may be used as shown in FIG.

When using the round pipe 6 and the roof mounting material 7 in combination, connect the round pipe 6 and the support column 1 via the connector 8 as shown in FIG. Attach by welding etc.

Various types of connectors 8 are possible, but the one shown in FIG. This is a flexible clamp that is attached so that it can rotate freely in the direction of arrow A-B in the figure.

The upper member 12 and the lower member 10 have the same structure but are combined in different orientations, with the upper member 12 oriented horizontally and the lower member 10 oriented vertically. Moreover, when the nuts 13 are loosened, the movable pieces 14 of both members 12 and 10 can be rotated outward, and when the nuts 13 are tightened, the columns 1 inserted into the vertical holes 9 and the horizontal holes 11, and the front and rear connecting members 2 formed by the pipes 6 are fixed respectively.

When only the roof attachment material 7 is used as the front and rear connection material 2, it is attached to the upper end of the support column 1 and slightly below it as shown in FIGS. 6 and 7.

The roof 4 is made of plastic film and is formed into a tube shape, for example. The plastic film that has been commonly used for this type of agricultural greenhouse may be used, but in that case, when it is installed at an angle between the front and rear connecting members 2 as shown in Fig. The lowest part 15, which is the lowest position, is made of polyvinyl alcohol film (PVA), which has no air permeability but has water absorbency.

In some cases, the entire roof may be made of a plastic film that is not breathable but has water absorption properties.

To attach the roof 4 between the attachment members 7 and 7 of different heights, for example, as shown in FIG. Then, insert the push tool 19 shown in FIG.
17 should be fixed. In this case, as shown in FIG. 7, one end 17 in the width direction of the roof 4 is extended to the end to form an opening/closing part 20, which is suspended below the roof attachment material 7, and is used for general purpose ventilation (not shown). The ventilation hole 23 may be formed in a stepped portion between the high portion 21 and the bottom portion 22 of adjacent roofs so as to be openable and closable by an opening/closing device. The opening/closing part 20 is not formed by extending one widthwise end 17 of the roof 4,
One side edge 17 of plastic film prepared separately.
At the same time, it may be fitted into the groove 18 of the roof attachment material 7 and attached to the pusher 19.

Effect of invention The air house of this invention has the following effects.

(1) A roof 4 made of plastic film is provided so as to be inclined laterally in the width direction, and the entire roof 4 or at least the lower lowest part 15 is formed of a plastic film that is not breathable but has water absorption properties. Therefore, water generated by liquefaction of moisture in the air injected into the roof 4 accumulates in the lower lowest part 15 of the roof 4, and falls near the pillar 1 through the water-absorbing plastic film. Therefore, the water droplets falling from the lower lowest part 15 of the roof 4 will fall on the edge of the field, and the vegetables grown in the field will never be damaged by being hit by the water droplets.

(2) Since the water accumulated on the roof 4 falls naturally, the roof 4 does not sag due to the weight of the water.

(3) Since the plastic film has water absorbency but is not breathable, air within the roof 4 does not escape.

(4) Since air can be freely taken in and out of the roof 4 using a blower or the like, the roof can be expanded or contracted as needed. Moreover, the roof 4
The insulating effect of the air inside the house maintains the temperature inside the house even during winter and at night when the temperature drops.
