Description

[Detailed description of the invention] The present invention relates to a board installation device, and more specifically, a board installation device suitable for attaching and detaching corrugated synthetic resin boards installed on the roof, wall, and gable of a greenhouse. Installation concerns the device.

Generally, greenhouses are used for growing vegetables, fruits, flowers and trees, or for cultivating fish, and these greenhouses consist of glass houses with transparent or translucent glass panels installed on the roof, walls, and gables, and transparent or translucent vinyl sheets. The developed greenhouses are becoming popular.

However, the transmittance of sunlight, especially ultraviolet rays, is less than 90% in glass houses, so the transmittance is poor, and the coloring of fruits such as pears and tomato is poor, and the quality is inevitably lower than that of natural products. Because glass itself is hard, it breaks easily, and when an external force is applied to it, such as the weight of a person climbing into a greenhouse, or when stones, roof straw, trees, etc. hit during a typhoon, the glass plate breaks and the glass pieces break. If glass falls into the soil inside the greenhouse, it is difficult to remove the pieces, and the glass plates themselves are expensive, so installing them on the entire surface of the greenhouse would make the construction cost of the greenhouse extremely high, making it uneconomical. The downside is that the size of the glass plate itself is limited, so it cannot be used in houses with large frontages, and when installing the glass plate, the number of parts for the fasteners is large and the cost is too high. be.

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. It is easy to tear when riding on it, its light transmittance is poor compared to glass, it is difficult to remove dirt when it adheres to the surface, it is difficult to work on the vinyl sheet roof, and the number of parts of this installation equipment is many,
Disadvantages include: increasing costs; re-covering the sheet is difficult as it is easily damaged; management is difficult; and the transmittance of sunlight is not good due to the fact that dirt adheres to it. It has the following.

For this reason, recently, greenhouses using corrugated panels made only of acrylic resin components have been developed and are becoming popular in place of the above-mentioned glass houses and vinyl greenhouses.

Acrylic panels made of acrylic resin have excellent transparency, ultraviolet transmittance, weather resistance, heat retention, etc., and are ideal as covering materials for greenhouses and other similar greenhouses.

In other words, acrylic panels have the following properties: ■ There is no loss due to light diffusion, reflection, or absorption, and the light transmittance is over 93%, so it prevents the occurrence of plant diseases and improves the coloring of fruits. ■ It is a composite material. Prevents the peeling and clouding of resin and fibers that often occur, and prevents rainwater and dirt from entering and contaminating the interior. ■It has excellent tensile strength and abrasion strength, and has a service life of more than 2 capes, so it can be used against typhoons and strong winds. - It can withstand other external forces and does not require repair or re-covering work, - The house itself has good airtightness and can be expected to save energy, - It comes in a wide range of standards and sizes, and is easy to install, and can be used even in large houses. ■Since it is cheaper than glass plates, it has the advantage of reducing greenhouse construction costs.

However, while acrylic panels have the advantages mentioned above, the method of mounting them has not been sufficiently researched other than by inserting hook bolts into the bolt holes, so it has the following major drawbacks. are doing.

That is, as shown in FIG. 11, when installing as a covering material on the roof, walls, and gables of a greenhouse, transparent corrugated acrylic panels 1 and 2 are stacked one on top of the other.

The upper end of the lower acrylic panel 1 is brought into contact with the pipe or C-shaped channel 3 that forms the framework of the greenhouse, and the lower end of the upper acrylic panel 2 is superimposed on the upper end of the lower acrylic panel 1 via the acrylic nonwoven packing 4, and then A bolt hole is drilled in the upper acrylic panel 2, a hook bolt 5 is inserted into the bolt hole, and the lower hook 6 of the hook bolt 5 is hooked onto the bent part of the pipe or C-shaped channel 3. The upper end is tightened and fixed with a nut 9 via a rubber packing 7 and a washer 8, and the upper end of the lower acrylic panel 1 is held between the C-shaped channel 3 and the upper acrylic panel 2 to provide some play. It has been devised so that it can be expanded and contracted freely.

However, the biggest flaw in the above installation method is that the bolt holes are drilled in the upper acrylic panel 2. ■When drilling this bolt hole with a tool, since the acrylic panel 2 is hard, it is difficult to drill the bolt holes when drilling the holes. A crack will occur from the position of the hole, and this crack will extend to the entire panel, making it unusable. ■Drilling multiple holes in the upper panel 2 makes the drilling work difficult, and it is difficult to prevent cracks from occurring. ■Even if the hole machining is completed successfully, stress will be concentrated on the bolt holes during long-term use during typhoons or when someone steps on the panel, and these external forces can cause complex cracks to form from the bolt holes. Due to the necessity of replacing parts and the drilling of a large number of 0 bolt holes, the hook bolt 5 to be penetrated through these holes is
, there are many parts such as the packing 7, which increases the parts cost, and [F] When inserting the hook bolt 5, two workers are required: one to hook it to the C-shaped channel 3 and the other to tighten the nut 9. [F] Furthermore, if the rubber gasket 7 becomes worn, rainwater and cold air will enter the greenhouse through the bolt holes, impairing heat retention and airtightness. It has the following drawbacks.

Therefore, the purpose of this invention is to connect multiple corrugated acrylic panels and other similar plates by simply attaching and detaching them with a single touch without drilling holes in the plates. It is an object of the present invention to provide an apparatus for mounting a plate suitable for use in a greenhouse, which significantly improves the installation and removal operations without causing any problems.

To achieve this objective, the present invention includes a clamping part that forms a plate insertion groove, a connecting part that horizontally connects a plurality of clamping parts, and an elastic retaining part provided downward from the clamping part. , are each integrally formed.

Although the configurations of the U-shaped portion 20 and the connecting piece 21 shown in FIGS. 2 to 4 are approximately the same, the lower piece 20
The structure of the lower part of b is different.

That is, the lower piece 20b has a hanging piece 26 that engages with the bent piece 14c connected to the upper piece 14a of the C-shaped channel 14.
and the horizontal piece 27 and the opening 2B of the C-shaped channel 14.
a vertical piece 29 that is inserted into the inner surface of the vertical piece 14b and joined to the inner surface of the vertical piece 14b; a horizontal piece 30 that is joined to the lower piece 14d of the C-shaped channel 14; and a retaining piece 31 that engages with the bent piece 14e of the C-shaped channel 14. are provided consecutively.

In addition, hanging piece 26, horizontal piece 27, vertical piece 29, horizontal piece 3
0 and the engaging piece 31 are linear, and the lower piece 20b1 horizontal piece 27 and the horizontal piece 30 are the vertical pieces 26 and 29.
are connected to each other to impart a relatively elastic action.

Similarly, the hanging piece 29 and the engagement piece 31 are relatively elastically applied via the horizontal piece 30.

The left and right rain hanging pieces 26 and 29 are inclined so as to gradually open downward, and are relatively elastically applied in the left and right direction.

Such attachment is carried out as follows in order to overlap and connect the upper and lower two acrylic panels 2 using the device 18a.

First, the lower surface of the upper end of the lower acrylic panel 1 is placed against the upper piece 14a of the C-shaped channel 14.

Next, both the left and right vertical pieces 26 and 29 are expanded, and the substantially U-shaped horizontal piece 27, vertical piece 29, and horizontal piece 30 are inserted into the opening 28 of the C-shaped channel 14, and the lower piece 20b and the horizontal piece 27, the upper piece 14a of the C-shaped channel 14 and the upper end of the acrylic panel 1 are elastically sandwiched, and each retaining piece 31 is inserted into the lower bent piece 14e from the inside to the outside. engage toward.

Thus, the horizontal piece 27, the vertical piece 29, the horizontal piece 30,
The engagement piece 31 is stably supported within the C-shaped channel 14 by applying elastic force in the direction of expanding the engagement piece 31 .

Next, the upper acrylic panel 2 has its lower end connected to the upper and lower pieces 20.
It is inserted into the gap 25 between a and 2Ob, and the other parts that are not inserted are superimposed on the upper surface of the upper end of the lower acrylic panel 1.

At this time, a downward spring force is applied to the upper piece 20a to hold the lower end of the upper acrylic panel 2 between it and the lower piece 20b.

Moreover, since the backing is interposed between the acrylic panels 1 and 2, the acrylic panels 12 are prevented from rattling or being damaged, and airtightness and heat retention are maintained.

In this way, the upper acrylic panel 2 is elastically supported between the upper piece 20a and the lower piece 20b, and is prevented from falling off to the acrylic panel 2. Even when an upward force is applied to the acrylic panel 2, the C-shaped channel 14, said vertical piece 29
Coupled with the fact that the holding is stable and reliable, sufficient holding force is ensured.

8 to 10 show a mounting device 18b according to a reference example.

This consists of a hanging piece that engages the bent piece 14c connected to the upper piece 14a of the C-shaped channel 14 on the lower piece 20b of both U-shaped parts 20, and an abbreviation that protrudes in the direction in which the U-shaped part 20 projects. A slanted piece 32 in the shape of a letter, a bent piece 33 in a substantially U-shape that extends in a direction substantially opposite to the protruding direction, and a protruding piece 34 that protrudes upward in a U-shape, continuing from the bent piece 33 and extending in a direction substantially opposite to the protruding direction. A hanging piece 35 that is somewhat longer than the width of the vertical piece 14b of the mold channel 14, a protruding piece 36 that is connected to the hanging piece 35 and protrudes downward in a generally U-shape, and a protruding piece 36 that is connected to the hanging piece 35 and that extends approximately upwardly. It consists of a bent piece 37 projecting in a U-shape.

Such attachment is carried out as follows to overlap and connect the two upper and lower acrylic panels 1 and 2 using the device 18b.

First, the lower surface of the upper end of the lower acrylic panel 1 is placed on the upper piece 14a of the C-shaped channel 14.

Next, push open the left and right rain hanging pieces 35 and
2 and the protruding piece 36 are inserted into the bent pieces 14c and 14e of the C-shaped channel 14, respectively.

After this insertion operation, let go of the hanging piece 35 and insert the inclined piece 3.
In each U-shaped portion of the bent piece 33 continuous to the bent piece 33 and the bent piece 37 continuous to the protruding piece 36, each bent piece 14c, 14
Fit it to e.

At this time, the ends of the inclined pieces 32 come into contact with the inner surface of the upper piece 14a of the C-shaped channel 14, and due to the return elastic force of each hanging piece 35 after the expansion, the bent pieces 33 and 37 of the C-shaped channel 14 It engages with the skewer pieces 14a and 14b so as to bite into them,
When attached to the C-shaped channel 14, the device 18b is held securely and stably.

Also, at this time, each inclined piece 32 is connected to the C-shaped channel 14.
Because it is in elastic contact with the lower surface of the upper piece 14a, the lower piece 2
0b forcibly presses the upper piece 14a and the lower acrylic panel 1 overlapped with the inclined piece 32, thereby preventing the acrylic panel 1 from freely coming off.

Next, the upper acrylic panel 2 has its lower end connected to the upper and lower pieces 20.
It is inserted into the gap 25 between a and 20b, and the other parts that are not inserted are overlapped with the upper surface of the upper end of the lower acrylic panel 1.

At this time, a downward spring force acts on the upper piece 20a to hold the lower end of the upper acrylic panel 2 between it and the lower piece 20b.

At this time, since the backing 4 is interposed between both acrylic panels 1 and 2 as described above, these acrylic panels
, 2 to prevent mutual displacement, damage, and rattling, reduce impact from external forces, and ensure airtightness and heat retention.

Thus, even if an unexpected upward force is applied to the upper acrylic panel 2, the installation of the device 18b is prevented due to the bending pieces 34, 37 biting into the bending pieces 14c, 14e of the C-shaped channel 14. from the C-shaped channel 14 of the upper acrylic panel 2 and the C-shaped channel 14 of the upper acrylic panel 2.
You can reliably prevent it from falling off.

According to the present invention, (1) Since holes are not formed in the acrylic panels 1 and 2, the hole forming work is omitted, and workability is significantly improved and costs can be reduced.

■ There are no bolt holes in panels 1 and 2, so there is no need to bolt them together, which greatly improves panel installation work, reduces the number of parts, and saves labor and costs.

(2) Since no holes are formed in the panels 1 and 2, there is no risk of cracks occurring in the panels during processing.

■ Panels 1 and 2 have no holes, which prevents rainwater and cold air from entering, ensuring airtightness and heat retention.

■ Since there are no holes in the panels 1 and 2, there is no risk of cracks occurring at the hole locations due to wind pressure from typhoons or the weight of people riding in the greenhouse.

■ Since the panels 1 and 2 can be installed by simply inserting them into the device, the work of installing and removing them is significantly improved.

■ Installation can be done by one person, and since the work is so easy that even an amateur can do it, it is possible to save on labor costs.

■ The number of parts required for installation is small because the device can be installed at desired locations and at key points.

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

Furthermore, the configuration of the present invention has the following unique effects.

That is, (1) Since it is integrally molded from an elastic wire material, it has a spring effect, is easy to mold, is lightweight, and is highly economical.

■ Since the connecting portion is curved in the shape of a mountain, it makes uniform contact with the top surface of the corrugated panel, and the panel is held well.

■ Since multiple holding parts are connected in the horizontal direction, it is possible to hold down the troughs of the corrugated panel at multiple locations, preventing the panel from wobbling and ensuring stability.

Since the pair of hanging pieces extending diagonally downward form a V-shape, the spring effect is increased, and when hooked into the channel, the spring effect prevents the item from coming off, resulting in excellent safety and stability.

Although the present invention describes in detail the installation of corrugated acrylic panels 1 and 2, the plate body may be a horizontal plate instead of a corrugated one, and the material may be metal, synthetic resin, wood, or other similar material. Can be used for everything.

Furthermore, the panels 1 and 2 may be transparent or semi-transparent, or completely opaque materials such as galvanized iron plates may be used.

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 for attaching plates such as tin roofs of other general houses.
