The above-mentioned conventional planters have achieved a certain effect from the viewpoint of their respective purposes of improvement, but there is still room for improvement from the actual use. Is what it is. That is, GRC
Is superior in strength to a planter made of ordinary concrete which has been widely used in the past, so that the plate thickness can be reduced and the weight thereof can be reduced, but there is a problem that heat is easily conducted. As for heat conduction, it is necessary to pay attention to heat damage to the soil due to its high heat conductivity. To prevent root rot of plant roots due to heat damage, the wall thickness (plate thickness) of the planter must be a certain value. Thickness is desired. Therefore, even though it can be formed thin as a planter by GRC, it requires a thickness that is not much different from ordinary concrete in practical use. Thus, although excellent in durability, it is extremely disadvantageous in terms of economy, handling, and the like.

As a solution to the above disadvantages of the GRC, a planter made of so-called lightweight cellular concrete is provided as disclosed in Japanese Utility Model Publication No. 1-5487, for example. In addition, there is a problem in durability in order to be installed outdoors such as a park where an unspecified number of people come and go and are likely to receive an unexpected impact.

The present invention has been made in view of the above-mentioned conventional problems, and provides a planter excellent in handleability by focusing on the advantages of GRC and the lightweight and heat insulating properties of lightweight cellular concrete. There is an object of the present invention where it is attempted.

[0007]

In order to achieve the above object,
The planter according to the present invention is an assembling type planter in which a wall material piece is erected around a base stand to form a required shape and dimensions, and the base stand is provided with a perimeter of a perforated bottom plate reinforced by a reinforcing frame. A wall plate is formed by joining a base plate provided with a material attachment allowance, and a wall material piece is composed of several pieces of unit plates forming the required planter outer dimensions. In addition to forming a bolt insertion hole that penetrates up and down, at least the required thickness of the outer peripheral side surface and the upper surface during assembly and the joint portion are made of glass fiber reinforced concrete, and the inside is made of lightweight cellular concrete. The above-mentioned wall material pieces are sequentially placed on the wall material piece mounting allowance of the base stand, and through bolts are inserted through the bolt insertion holes of the splicing portion into the base stand to integrally connect adjacent wall material pieces. In which was to be Tightened to the base table to.

[0008]

[Function] The outer periphery of the planter, which is susceptible to impact, is GR
C and the inside is made of lightweight cellular concrete,
Lightweight and excellent in heat insulation performance and strength. Further, assembling of the planter is possible only by placing each wall material piece on the base table and tightening it with a through bolt, and can be easily assembled without special skill. By using this assembling type, even if the assembling dimensions are large, it is possible to make the form easy to transport separately to the installation site, and to improve the transportation efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially omitted perspective view showing the structure of the assembly type planter according to the present invention. In the figure, planter P
Consists of a steel base 1 and a wall piece 2.

The base 1 has a perforated bottom plate 3 made of a punched metal, an expanded metal, or the like, which is reinforced by a replenishing frame 4 to prevent the outer periphery and an intermediate portion of the perforated bottom plate 3 from bending, and a base plate 5 is joined to the outer periphery of the lower surface thereof. The base plate 5 projects further outward than the outer periphery of the reinforcing frame 4, and the projected portion is used as a mounting margin 5 a for the wall material piece 2. A bolt fastening hole 5b of a through bolt B for fastening the wall material piece 2 when necessary is formed at the wall material piece fastening position of the base plate 5.

In the embodiment, the binding holes 5b are formed at four corresponding corner portions because the base table 1 has a rectangular shape so as to form a rectangular planter P with four wall material pieces 2.

Reference numeral C denotes a caster, which is mounted on the lower part of the reinforcing frame 4 in a required number to make it easy to move. However, instead of the caster C, a bolt leg whose height can be adjusted is provided, or both casters are arranged in parallel. It is also possible to set it according to the use mode of the planter P.

The wall member 2 is formed as a unit plate having a required height and width so as to form a required shape at the time of assembling a planter. The wall material piece 2 has both side ends formed in the shape of the splicing connection 6, and the number of the mortises 6a on both sides is set so that the wall material piece 2 can be sequentially connected to the adjacent wall material piece 2. I have. And
A bolt insertion hole 2a is formed at an intermediate portion of each tenon 6a, that is, at a portion where the through bolt B is inserted concentrically when the respective wall material pieces 2 are joined as a joint.

The wall material 2 is made of GRC (glass fiber reinforced concrete) 21 and lightweight cellular concrete 22.
Molded in two layers. That is, the required thickness of the joint 6 and the outer side and upper and lower surfaces during assembly is GRC, and the other inner surfaces are lightweight cellular concrete 2.
It is 2. In this case, the layer thickness of the GRC 21 on the outer peripheral side surface and the upper and lower surfaces may be set to, for example, about 10 mm in the case of a wall material piece having a thickness of 50 mm. In short, when the main material is the lightweight cellular concrete 22, it is sufficient that the concrete can be reinforced easily to the extent that it is not easily chipped or broken by an external impact. Therefore, it is also possible to form the GRC 21 only on the outer peripheral side surface and the upper surface in addition to the joint portion 6 or to form the lightweight cellular concrete 22 so as to cover the entire surface with the GRC 21.

The production of the wall material pieces 2 is possible by general means. For example, a lightweight cellular concrete plate molded to a required size is prepared in advance, and when the slurry of GRC22 is poured into a predetermined formwork corresponding to the size of a wall material piece, the lightweight cellular concrete plate is buried almost at the same time. Means for curing and integrating, or conversely, means for forming an outer body by GRC with a hollow inner surface in advance, filling it with lightweight cellular concrete slurry, and curing and integrating Various methods can be used, such as means for fitting and integrating the two.

In the above configuration, when assembling the planter P, the completed base table 1 and the wall material pieces 2 are produced at a factory. Then, they are transported to the planter P installation site as members that have been divided. At the installation site, the wall material pieces 2 are sequentially placed on the wall material piece mounting allowance 5a of the base table 1, and the tenon 6a is joined and spliced. Then, the bolt B is inserted through the bolt insertion hole 2a of the joint portion and the bolt tightening hole 5b of the base 1 to insert the base 1
A nut (not shown) is screwed and tightened from the lower surface of the. The nut may be previously joined to the lower surface of the bolt fastening hole 5b of the base 1 by welding or the like. The above operation completes the assembly of the planter P.

When the above-mentioned assembled planter P is filled with a required culture soil or the like, a considerable earth pressure is applied to the joint 6 of the wall piece 2, but this joint has sufficient strength. Nag
By molding with RC, it can withstand sufficiently.
