Description

[Detailed Description of the Invention] The present invention relates to a board mounting device, and more specifically, it is suitable for attaching and detaching boards such as corrugated synthetic resin boards installed on the roof, walls, and gables of greenhouses. This invention relates to a plate mounting device.

Greenhouses are used for growing vegetables, fruits, flowers and trees, or for cultivating fish.There are two types of greenhouses: glass houses with transparent or translucent glass panels installed on the roof, walls, and gables; Vinyl greenhouses made of vinyl sheets have been popular for a long time.

However, glass houses have poor transparency because the transmittance of sunlight, especially ultraviolet rays, is less than 90%, and the coloring of vegetables and fruits, such as pears and tomatoes, is poor, and the quality is inevitably lower than that of natural ones. Since the glass itself is hard, it breaks easily, and when external force is applied to it, for example, when a person climbs into a greenhouse, or when a stone blown away by a typhoon, straw on the roof, or a tree hits the glass plate, the glass plate breaks. However, if the glass fragments fall into the soil in the greenhouse, it will be difficult to remove them.The glass panels themselves are expensive, so if they are installed all over the greenhouse, the cost of constructing the greenhouse will be extremely high. It is not economical, and the size of the glass plate itself is limited.
Disadvantages include that it cannot be used in houses with large frontages, and that the number of parts required for fixing the glass plate is too large and the cost is too high.

In addition, although vinyl houses are relatively easy to construct and cost-effective compared to glass houses, they lack durability because the vinyl sheets themselves are thin sheets, and are susceptible to external forces such as feng shui and people. The light transmittance is poor compared to glass, it is difficult to remove dirt when it gets on the surface, it is difficult to work on roofs with vinyl sheets, and the number of parts of the installation equipment is difficult. There are many problems, such as increasing costs, the fact that the sheet is easily damaged, making it difficult to replace it, and it is difficult to manage it, and the transmittance of sunlight is not good, as it also attracts dirt. It has the following drawbacks.

For this reason, in recent years, instead of the above-mentioned glass houses and plastic greenhouses, greenhouses using corrugated plates made only of acrylic resin components, that is, acrylic panels, have been developed and are becoming popular.

Acrylic panels have excellent transparency, ultraviolet transmittance, weather resistance, and heat retention properties, making them ideal as covering materials for greenhouses and similar greenhouses.

In other words, acrylic panels can diffuse and reflect light,
There is no loss such as absorption, and the light transmittance is over 93%, so it prevents the occurrence of plant diseases, improves the coloring of fruits, and prevents peeling and clouding of resin and fibers, which often occur with composite materials, and rainwater. It has excellent tensile strength and abrasion strength, and has a service life of over 20 years, so it can withstand typhoons, strong winds, and other external forces, and does not require repair or reupholstery. The greenhouse itself has good airtightness and can be expected to save energy; it comes in a variety of standards and sizes, making it easy to install; it can also be used in large greenhouses; it is cheaper than glass panels, so the cost of constructing the greenhouse is also low. It has the advantage of being able to be downloaded.

However, although acrylic panels have the above-mentioned advantages, the mounting method other than inserting hook bolts into bolt holes has not been sufficiently studied.

That is, as shown in Fig. 8, when installing as a covering material on the roof, wall, and gable of a greenhouse, plates 1 and 2 made of transparent corrugated acrylic panels are stacked one on top of the other. The upper end of the lower plate 1 is brought into contact with the pipe or C-shaped channel 3 that forms the frame of the greenhouse, and the lower end of the upper plate 2 is superimposed on the upper surface of the lower plate 1 via the acrylic nonwoven fabric packing 4, and then , a bolt hole is drilled in the upper plate body 2,
The hook bolt 5 is inserted into this bolt hole, the lower hook 6 of the hook bolt 5 is hooked onto the pipe or the bent part of the C-shaped channel 3, and the upper end of the hook bolt 5 is tightened and fixed with a nut 9 via a rubber packing 7 and a washer 8. The upper end of the lower plate 1 is held between the C-shaped channel 3 and the upper plate 2 to give it some play, so that it can freely expand and contract in summer and winter.

However, the biggest drawback of the above installation method is that bolt holes are drilled in the acrylic panel serving as the upper plate 2. Therefore, when drilling these bolt holes with a tool, since the acrylic panel is hard, cracks may occur from the hole position when drilling the holes, and these cracks may extend to the entire panel and make it unusable. The holes are to be drilled at multiple locations on the upper plate 2, making the hole drilling work difficult and requiring careful work to avoid cracks.
Even if the hole machining is completed successfully, stress due to external forces will concentrate on the bolt hole part during long-term use, and complex cracks will occur from the bolt hole, making it easy to have to replace the plate. A hook bolt 5 which is penetrated by a large number of holes,
There are many parts such as packing 7, which increases the overall cost, and when inserting the hook bolt 5, C.
Two people are required, one to hook the mold channel 3 and the other to tighten the nut 9, which increases labor costs and makes attachment and detachment troublesome.Furthermore, if the rubber gasket 7 wears out, rainwater can leak through the bolt hole. This method has drawbacks such as the fact that cold air can enter the greenhouse, impairing heat retention and airtightness.

Therefore, the purpose of the present invention is to provide a method for joining a plurality of corrugated acrylic panels and other similar plates.
To provide a mounting device for a plate body suitable for use in a greenhouse, capable of attaching and detaching the plate body with a single touch without making holes in the plate body, and significantly improving attachment and detachment work without damaging the plate body.

In order to achieve this objective, the configuration of the present invention is applied from a wire body to a plate attachment device that connects a plurality of corrugated plates formed by alternately connecting curved peaks and valleys. A pair of left and right panel holding parts are provided, each having a main body and a holding piece, and a plate insertion part formed between the main body and the holding piece, and these panel holding parts are mountain-shaped panels made of wire bodies. They are integrally connected via a holding part, and the main body is further provided with a hook-shaped hook piece facing downward, and the valley part of the plate body is inserted into the insertion part, and the panel holding part is fitted to the peak part of the plate body. It is characterized by allowing

The presser piece 34 is forcibly rotated clockwise in FIG. As a result, the main bodies 30, 30 of the panel holding parts 28, 28 and the C-shaped channel 37 hold the troughs 1a in the corrugations of the lower plate 1 with clamping pressure, and the mounting device 18 connects to the C-shaped channel 14. It can be attached to the lower plate 1 by a so-called one-touch operation and without requiring any other parts.

Next, the lower end of the upper plate 2 is inserted into the gap 35 between the main body 30 and the holding piece 34. As a result, the valley portion 2a of the upper plate 2 is held between the main body 30 and the presser piece 34, and the presser piece 34 presses the upper plate 2 by the spring force of the curved portion 33. At this time, the panel holding part 29 fits onto the upper surface of the upwardly curved peak part 2b of the upper plate body 2, and presses the curved part 3
The upper plate body 2 is pressed down by the spring force of the holding piece 3 and the holding piece 34. Therefore, the upper plate 1 is the main body 3

It is held within the gap 35 by the pressing force of , and is prevented from coming off. A packing 4 is provided on the top surface of the upper end of the lower plate 1, that is, on the top surface of the mountain portion 1b, and this packing 4 prevents rattling when the two plates 1 and 2 are overlapped, prevents misalignment, Preventing damage due to misalignment,
The aim is to provide a buffering effect against external forces.

5 to 7 show a mounting device 18a according to a reference example, which is substantially the same as the embodiment shown in FIG.
The only difference is that there is only one 8a.

The mounting device 18a has a panel holding section 28.
It consists of a single body 36 consisting of a horizontal linear body, a supporting piece 37 with one end of the main body 36 bent downward, and a hook with the lower end of the supporting piece 37 bent towards the main body 36 side. A piece 38, an upwardly curved portion 39 formed by bending the other end of the main body 36, a presser piece 40 that is bent from the curved portion 39 toward the main body 36 and faces the main body 36, and is formed between the main body 36 and the presser piece 40. It consists of a gap 41 which is an insertion part for inserting a panel.

The holding piece 40 is pressed against the main body 36 by the spring force of the curved portion 39.
A guide piece 42 is formed at the end of the presser piece 40 and bent upward, but the guide piece 42 can be used without it.

When attaching the upper and lower plates 1 and 2 using the above-described attachment device 18a, first, the upper end of the lower plate 1 is brought into contact with the C-shaped channel 14. Next, the hooking piece 38 of the attachment device 18a is hooked onto the bent portion 14' of the C-shaped channel 14, and the supporting piece 37, main body 36, and presser piece 40 are rotated clockwise in FIG. As a result, the main body 36 is brought into contact with the upper surface of the trough 1a of the lower plate 1, and the trough 1a is strongly held between the main body 36 and the C-shaped channel 14, and the attachment device 18a is attached to the C-shaped channel. 14 and is fixed to the lower plate 1.

Further, the packing 4 provided on the lower plate 1 prevents the upper plate 2 from rattling, prevents displacement, and has a cushioning effect against external forces.

Next, the lower end of the upper plate 2 is inserted into the gap 41 while being guided by the guide piece 42, and the main body 36 and the holding piece 40 clamp and press the trough 2a of the upper plate 2 from above and below to hold it. At this time, the presser piece 40 is
The trough is pressed down with a spring force of 9. In addition, since a gasket 4 is interposed between the upper and lower plates 1 and 2, the panels 1 and 2 are prevented from shifting, being damaged, and rattling, and absorbing and mitigating shocks from external forces. Airtightness and heat retention will be ensured.

Incidentally, part or all of the mounting device according to the embodiment shown in FIGS. 1 to 4 and the reference example shown in FIGS. This coating prevents the mounting device from slipping and falling or wobbling, and also absorbs and alleviates impact energy even if a load is applied to the plate or the mounting device.

As described above, the present invention has the following effects.

There are a pair of left and right panel holding parts, and since the panel holding part has a mountain shape in the center, the panel holding part holds the troughs of the corrugated plate and follows the shape of the crests. The panel holding section is then fitted, and the plate can be held in three places, providing a large holding force and stably holding the plate.

By holding the corrugated plate at three locations, it is possible to prevent not only the plate but also the mounting device itself from shifting or coming off.

Since the attachment device itself is held on the channel via a hook-like hook, it can be attached and detached with a single touch, significantly improving work efficiency.

The main body, the pressing piece, and the panel pressing portion are integrally formed from a wire, so that they can be easily formed by simply bending them.

Since holes are not formed in the acrylic panels 1 and 2, which are corrugated plates, the hole forming work is omitted, and workability is significantly improved and costs can be reduced.

There are no bolt holes in the panels 1 and 2, and there is no need to bolt them together, so the panel installation work is significantly improved, the number of parts is reduced, and labor and cost reductions can be achieved.

Since there are no holes in the panels 1 and 2, rainwater and cold air can be prevented from entering, ensuring airtightness and heat retention.

Since the panels 1 and 2 are simply inserted into the mounting device, the work of attaching and detaching them is greatly improved.

The installation work can be done by one person, and since the work is so easy that even an amateur can do it, labor costs can be saved.

The number of parts can be reduced because the mounting device is simply installed at the required locations.

Since the panels 1 and 2 are simply held together, they can freely expand and contract depending on temperature changes, and there is no risk of them breaking.

Although the present invention details the installation of acrylic panels as corrugated plates, the plates can be made of metal, synthetic resin, wood, or any other similar material. The plate may be transparent or semi-transparent, or it may be completely opaque, such as a galvanized iron plate.

Furthermore, although the device of the present invention is most suitable for use with corrugated panels on the roofs of greenhouses, it goes without saying that it can also be used to attach plates such as tin roofs of other general houses.
