Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a fastening fitting for vinyl house pipes, which is used to fasten double arch rods made of pipes at a constant interval in a vinyl house. It is something.

[Problems to be solved by conventional techniques and ideas]

Conventionally, greenhouses for greenhouse cultivation were made with a single layer of vinyl, but recently, in order to reduce heating costs (fuel), it has been devised that greenhouses are covered with two layers of vinyl to increase the room temperature effect. It has come to be.

Conventionally, metal fittings for securing the arch rods of such a double-layered greenhouse by maintaining a constant interval have been disclosed in, for example, Japanese Utility Model Application No. 58-59447 and Japanese Utility Model Application No. 54-39333. It is extremely troublesome to tighten and fix the plastic greenhouse to the opposing arch rods one by one using bolts, etc., which has the disadvantage of reducing the efficiency of the greenhouse assembly work.

The present invention solves these two drawbacks.
The present invention provides pipe fastening fittings for greenhouses used in heavy-structured greenhouses.

[Means to solve the problem]

The gist of the present invention will be explained with reference to the accompanying drawings.

Support plates 4 are provided at both left and right ends of an arch spacing regulating body 2 that is equal to the spacing between the inner and outer arch rods 1 constituting the greenhouse, and both side edges of the left and right support plates 4 are bent into a channel shape at both ends, respectively. Engagement part 4'
The pipe holding plate 5 is provided with angle engaging pieces 5' on both ends that engage with the front engaging piece 4'' of the engaging portion 4'. This relates to a pipe fastening fitting for a vinyl house, characterized in that it is press-fitted and fixed to the support plate 4 by being locked inside the pipe.

[Effect]

A supporting plate 4 is provided with opposing arch rods 1 provided in a double layer, and is provided at both left and right ends of an arch spacing regulating body 2, and has engaging portions 4' formed at both ends with both side edges bent into a channel shape. It consists of a pipe holding plate 5 having angle engaging pieces 5' on both side edges that engage with the inside of the front engaging piece 4'' of the engaging part 4' of the support plate 4,
By locking the angle engagement piece 5' inside the front side engagement piece 4'', the pipe holding plate 5 is held by the fastening fitting 3 constructed by press-fitting and fixing the pipe holding plate 5 to the support plate 4, and a predetermined interval is maintained. and bond together.

〔Example〕

Inner and outer arch rods that make up the greenhouse 1
(Made of pipe) Support plate 4 that tightly connects the inner and outer arch rods 1 to both ends of the arch spacing regulating body 2 that is equal to the spacing.
and a pipe holding plate 5 that is press-fitted and fixed to this support plate 4.
A fastening fitting 3 consisting of these is provided to form a pipe fastening body a.

The fastening fitting 3 shown in the drawing is a wedge type in which a pipe holding plate 5 is press-fitted to a support plate 4.

FIG. 1 shows a pipe binding body a in which such binding fittings 3 are riveted to both ends of an arch spacing regulating body 2 made of a square pipe. (Welding or bolting may be used instead of riveting.) Figure 2 shows a pipe clamping body a in which support plates 4 are riveted to both ends of an arch spacing regulating body 2 formed into a U-shape by press working. There is.

Fig. 3 shows an arch spacing regulating body 2 formed by pressing a single plate into a U-shape, with supporting plates 4 on both end surfaces, and channel-shaped engaging portions 4' on both left and right ends of the plate. This figure shows an integral type of pipe binding body a formed with. (6 is the vinyl, 7 is the trunk rim.) [Effects of the invention] Since the invention is constructed as described above, the inner and outer arch rods 1 are double provided at regular intervals in the vertical direction of the greenhouse. A predetermined space is formed between the inner and outer arch rods 1 by tightening one side with one support plate 4 and pipe holding plate 5 of the pipe tightening body a, and similarly tightening the other side with the other support plate 4 and pipe holding plate 5. It is possible to maintain the distance and tighten.

In particular, the present invention provides a support plate 4 which is provided at both left and right ends of the arch spacing regulating body 2 and has engaging parts 4' formed at both ends with both side edges bent into a channel shape, and an engaging part of this support plate 4. It consists of a pipe holding plate 5 with angle engaging pieces 5' on both side edges that engage with the inside of the front engaging piece 4''. By fixing the pipe holding plate 5 to the support plate 4 by press-fitting it, the inner and outer arch rods 1 can be easily tied together while maintaining a predetermined distance from each other. The assembly work will be improved.

Furthermore, since the structure of the proposed product is simple, it can be mass-produced by press processing, and it has excellent practical effects such as providing the product at a correspondingly low cost.
