Description

[Detailed description of the invention] <<Technical field of the invention>> This invention relates to a rooting system for promoting the self-reliance of the pillars of agricultural structures and preventing the pillars from tipping or sinking.

<<Prior art and its problems>> In the field of agriculture, various structures with pillars are installed, such as windbreak net facilities. If the structure is to be fixed for a long period of time, the pillars are generally supported by pouring concrete at the base, but in the case of agricultural structures that are to be dismantled and moved in a short period of time, it is not economical to fix the pillars with concrete. and unsuitable in terms of resilience.

Conventionally, when fixing with concrete was not done and sufficient stays could not be obtained,
The pillars were made to stand on their own by using root chains as shown in B. A is a drive-in type root clamp, and a vertical tilt prevention plate 1 is installed around a cylindrical body 10 with a pointed lower end.
2, 12, . . . are installed radially. This is driven into the soil, and the lower end of the column is inserted into the cylindrical body 10. In addition, B is an embedded type of root holder, and the cylindrical body 1
A horizontal plate 14 is attached to the lower end of the column, which is buried in the soil, and the lower end of the column is attached to the cylindrical body 10.
Insert into.

Although the anti-tilt plate 12 has a considerable effect on preventing the column A from tipping, there is almost no resistance in the vertical direction, so almost no effect on preventing the column from sinking can be expected. Although the horizontal plate 14 of the root anchor B can be expected to have a sufficient effect of preventing subsidence, it is not possible to effectively prevent the column from tipping unless the horizontal plate 14 has a considerably large area.

In addition, all of these conventional root chains are very large and are extremely difficult to store.
Therefore, there is a problem that the transportation cost and storage cost until the product reaches the user increases, and it also requires a lot of space to store in the warehouse of the farmer, which is very inconvenient.

[Purpose of the invention] The purpose of this invention is to provide a root anchor for agricultural structures that has a large effect on preventing pillars from tilting and sinking, and which can be easily assembled using small parts that are easy to store. It's about doing.

<<Structure of the invention>> The root cage according to this invention which achieves the above object includes a plurality of main parts formed in the same shape and a subsidence prevention plate, and the main parts extend around the outer periphery of the column at equal angular intervals. a surrounding curved portion; a tilt prevention plate that is formed integrally with the curved portion and extends vertically at a predetermined angle from one end thereof; a mounting portion provided at the other end of the curved portion; and the tilt prevention plate. a slit formed horizontally from one end at an intermediate position;
The subsidence prevention plate is formed into a circular arc shape, and is formed into a ring shape by combining a plurality of plates in the circumferential direction, and has connecting parts at both ends, and when in use, the mounting parts are connected to each other. By connecting bolts and nuts to the column, a cylindrical portion is formed that grips the column at the curved portion, and the tilt prevention plates are arranged radially around the cylindrical portion, and the subsidence prevention plates are inserted into the slits. The anti-tilting plate and the anti-subsidence plate are arranged so as to be perpendicular to each other by fixing them to each other with bolts and nuts via the coupling portion.

<<Embodiment>> FIGS. 2, 3, and 4 show an embodiment of the present invention. The anchor of this embodiment is constructed using three main parts 20 of the same shape as shown in FIG. 2 and two subsidence prevention plates 30 of the same shape, and each member is made of a metal material such as a steel plate.

One main part 20 includes a curved part 22 that covers the circumferential surface of the column 50 by 120 degrees, a tilt prevention plate 24 continuous to one side of the curved part 22, and a continuous width part 24 to the other side of the curved part 22. A small mounting plate 26 is provided. The tilt prevention plate 24 and the mounting plate 26 are formed in the radial direction to maintain an interval of 120° with respect to the arc center of the curved portion 22. There are two bolt holes 27 on the mounting plate 26.
Similarly, two bolt holes 27 are formed at the base of the tilt prevention plate 24. Further, a slit 28 formed horizontally from one side end is provided in the central portion that divides the height of the tilt prevention plate 24 into two.

The subsidence prevention plate 30 is a substantially semi-circular donut plate, and a coupling margin is provided at both ends thereof, and a bolt hole 32 is formed in the coupling margin. The inner and outer diameters of the subsidence prevention plate 20 are approximately equal to the distance from the arc center of the curved portion 22 to the inner end of the slit 28 and the distance to the outer edge of the tilt prevention plate 24. Further, the thickness of the subsidence prevention plate 30 is slightly smaller than that of the slit 28.

To assemble the root kase of the present invention, as shown in FIG.
2 to form one cylinder. At this time, the tilt prevention plate 24 of one main component 20
and the mounting plate 26 of the other main part 20 face each other and come into contact with each other, and their respective bolt holes 27 coincide with each other. Bolts and nuts 29 are installed in the matching bolt holes 27 to fix them together. As a result, the three main parts 20 are integrally assembled.

Next, for the assembly of the three main parts 20, insert the two subsidence prevention plates 30 into the slits 2 of the tilt prevention plate 24.
8, the two subsidence prevention plates 30 are overlapped with the connecting margins at both ends, the bolt holes 32 are aligned with each other, and bolts and nuts 34 are installed there to integrally connect the two. At this time, the subsidence prevention plate 30 is perpendicular to the tilt prevention plate 24.

As shown in FIG. 4, the curved portions 22, 22, 22
When the lower end portion of the column 50 is inserted and fixed into the cylindrical portion made of They are arranged horizontally across 24 spaces. By burying the roots in the soil, the pillar 50 becomes self-supporting, and the sinking prevention plate 30 effectively prevents the pillar 50 from sinking. is effectively prevented from tilting.

Furthermore, the root cage of the present invention can be disassembled, stored, and transported when not in use. A large number of the main parts 20 and the subsidence prevention plates 30 can be stacked and stored in a very high density, thereby reducing transportation costs and storage costs.

In the above embodiment, the pillar 50 is held by three main parts 20, but the present invention is not limited to this, and the pillar 50 can be constructed by assembling two or four or more parts. You can also. Similarly, a set of three or more subsidence prevention plates may be used.

《Effects of the invention》 As explained in detail above, the root anchor of the agricultural structure according to this invention has a structure that can be assembled at the time of use using small and easily stored parts, so it can be disassembled and compacted when not in use. It can be stored in a large amount of space, which reduces transportation costs. Furthermore, when assembled at the time of use, both the subsidence prevention plate that effectively prevents the column from sinking and the tilt prevention plate that effectively acts to prevent the column from tipping form a sufficiently large anchorage, and its performance is improved compared to conventional ones.
