Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an exhibition tower device used as a monument at an exhibition hall, an exhibition hall, or the like.

(Prior Art) Conventionally, as a plant growing device that can be installed on an upright wall surface in a structure or the like without using soil, for example, Japanese Utility Model Publication No. 55-3799, Japanese Utility Model Publication No. 52-1639, According to Japanese Patent Publication No. 50-16910, etc., and in this type of plant cultivating apparatus, a type using soil is, for example, Japanese Utility Model Publication No. 63-104417, Japanese Patent Publication No. 63-26253, Japanese Patent Laid-Open No. 53253/1983.
-5823 and the like are publicly known.

(Problems to be solved by the invention) However, the former plant growing apparatus of this type, that is, the one without soil, is an open-cell foam such as polyurethane foam, a polyvinyl chloride monofilament, or a natural fiber as a growing bed. Since it is a hydroponic type that uses water, it is necessary to supply the fertilizer-containing water to the growing bed without interruption, which requires special equipment and troublesome labor and is not suitable for hydroponic cultivation. There is a problem that suitable plants cannot be cultivated by this, and the latter, that is, the type of using soil, fills the soil into the body of a specially constructed hollow plate or housing and the body. A hole is opened in the front of the plant, and the plant is planted in the soil and the seeds are sown through the hole, so the whole structure is complicated and the planting seeds are sown. Not only is the work troublesome, but there is also the problem that the soil inside the container may spill from the above-mentioned holes.

(Means for Solving the Problem) The present invention is a means for spinning a large number of thermoplastic synthetic resin filaments downward from a nozzle and pulling them out at a drawing speed slower than the swelling speed while these filaments are not yet solidified. The inside of a flat three-dimensional reticulated aggregate having fine meshes for soil retention on the surface and edge surface obtained by curving with a line and intersecting the filaments by this winding and fusing the intersections and then solidifying by cooling. It is an object of the present invention to solve such a problem by providing an exhibition tower device in which a plant cultivation device configured by filling and holding a soil in a void portion is attached to an outer surface of a tower body substantially vertically.

(Example) An upper ring 4 having a diameter of about 3 m, in which a large number of hooks 1 are provided on the entire outer circumference, and a plurality of hooks 3 are similarly provided on the entire outer circumference, at the upper end of a triangular column 2 having a height of about 12 m. Is fixed in a state in which it is laid horizontally and in a state in which it surrounds the upper end, and a large number of hook portions 6 are provided on the entire outer surface around a portion of the triangular prism portion 2 slightly higher than the height of the human head. Lower ring 7 of about 6m
Are laid horizontally and floated in the air, and the lower ring 7 is attached to the upper ring 4 by a plurality of wires 8.
It is hung by and the tower 9 is obtained.

Further, the thermoplastic synthetic resin filaments 11 are spun downward from a plurality of downward nozzles (not shown) provided in the extruder die separately from the tower 9 and the filaments 11 are formed. While still not solidifying, the surface and the edge surface are made to bend by a means of taking out with a drawing speed slower than the spinning speed, and the wire 11 is crossed by this winding to fuse the intersection, and then to solidify by cooling. Flat three-dimensional net structure with a thickness of 3 to 7 cm, which has a fine mesh 12 for soil retention
3, the culture soil 14 is sufficiently filled and held in all the internal void portions of the three-dimensional reticulated structure 13, and the back plate of the three-dimensional reticulated structure 13 is made of plastic corrugated board for preventing the culture medium from falling off. 15 is placed, and a frame 17 with hooks 16 obtained by assembling a thin metal rod into a cross girder is arranged on the outside of the contact plate 15 and a puncture stop projection 19 with a plurality of barb needles 18 is provided on the frame 17. The three-dimensional net-like structure 13, the hitting plate 15 and the frame 17 are integrated by sticking the equal puncture stopping projections 19 to the touch plate 15 and the three-dimensional net-like structure 13 to obtain a large number of plant cultivation devices 20.

Furthermore, after sowing seeds or planting seedlings on these plant cultivation devices 20, the whole is placed horizontally on a flat place and cultivated, and when it grows to a certain degree or when flowers come into appreciation time The entire device 20 is fixed to the entire outer circumference of the tower main portion 2, the entire outer circumference of the upper ring 4 and the entire outer circumference of the lower ring 7 by hooking the hooks 16 onto the hook portions 1, 3, 6 so as to be detachable. Has been completed.

Another different plant cultivation device shown in FIG. 5 has a chamber 21 and a watering hole 22.

(Operation and effect of the invention) The present invention firstly sows the seeds or seedlings in the soil filled and retained in the internal voids of the three-dimensional net-like aggregate, and then lays them horizontally on a flat place and raises them to a certain extent. At the time of growing up, the entire plant cultivating device is obtained by, for example, hanging and decorating it on a vertical wall on the outer surface of the tower main body, and in particular, the display tower device in the present invention is thermoplastic as shown above. A large number of synthetic resin filaments are spun down from the nozzle, and while these filaments are not yet solidified, the filaments are made to bend with a means of taking them out at a drawing speed slower than the spinning speed and the filaments are made to cross each other by this meandering It is composed of a flat three-dimensional reticulated aggregate obtained by fusing the crossing points and then solidifying by cooling, and the soil filled and held in the internal voids of the three-dimensional reticulated aggregate. formula Unlike that, it does not require constant supply of fertilizer-containing water to the growing bed, does not require special equipment and troublesome labor for this, and it does not require any selection of plants to be cultivated, and In the present invention, when the soil is used as described above, each of the filaments forming the three-dimensional net-like aggregate filled with the soil and the roots of the plant grown in this soil firmly hold the soil and the soil is applied to one of them. In addition, it is possible to prevent deviation, etc. In addition, since the three-dimensional net-like aggregate has a fine mesh portion for soil retention on the surface and the edge surface, the soil in the three-dimensional net-like body is prevented from spilling outward. The present invention can be surely prevented, and the present invention can achieve the effect of sufficiently solving the above problems.
