Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative pillar structure of a building, and is constructed in a state of being exposed to the outside and has a design function, like a front porch pillar arranged at a front edge of a front porch. The aim of this project is to apply technology for planting the decorative pillars.

[0002]

2. Description of the Related Art Plants such as ivy crawl on the wall of a building for growth, and plant cultivation containers and flower pots are attached to the wall to green the wall. Growing plants directly on the wall requires techniques for plant management and maintenance, and is difficult in ordinary houses. There is also a concern that the roots and stems of the plant may damage the wall material. Furthermore, when the plant is removed from the wall on which the plant was growing, traces of the plant growing on the wall are clearly left as irregularities or discoloration, and the appearance is extremely poor.

[0003] Therefore, it has been proposed to prepare a greening member provided with plants separately from the wall surface and attach the greening member to the wall surface. JP-A-1-43140 discloses an apparatus having a structure in which a root holding body such as rock wool is attached to a plate-shaped wall protection member, and a plant is planted in the root holding body. By arranging such devices on a wall surface and fixing the back surface of the wall protection member to the wall surface with bolts, the wall surface is greened by plants. Water is supplied to the root holder through a water pipe. Next, in a building, a decorative pillar may be provided on an entrance porch or the like. The structure of a general decorative pillar is a core pillar made of steel, etc., which functions as an original pillar that supports loads such as the entrance roof,
It is composed of a decorative surface material that covers the outside of the core pillar material and exerts an external design effect. As the decorative surface material, various inorganic boards, wood materials, synthetic resin materials, and the like similar to wall surface finishing materials for buildings are used.

[0004] In order to apply a greening treatment to such a decorative pillar structure, a flower pot or a planter in which a plant is planted is suspended from the outside of the decorative pillar, or ivy or vine is crawled from the root of the decorative pillar. Covering is done.

[0005]

The above-mentioned JP-A-1-431
In the prior art disclosed in Japanese Patent Publication No. 40, there is a problem that the entire device for greening is attached to the front surface of the wall so as to protrude greatly, so that the bulk is increased and the appearance is not good. Since the plate and frame material for holding the plants are exposed and overhanging on the surface, they will inevitably give a mechanical and rugged impression, greatly impairing the environmental improvement effect of the natural appearance of the plants. . Since the root holding body that holds the plant is merely attached to the surface of the plate-shaped wall protection member, it is not possible to sufficiently hold the water and nutrients required for the plant. For this reason, in the above-mentioned conventional technology, water is supplied by a water pipe. However, the water pipe and its related structure are also exposed on the front surface of the wall surface, which impairs the appearance.

[0006] Since the prior art is intended for greening the wall of a structure such as concrete, all the device structures must be mounted in front of the wall of an existing structure. It will happen. Similarly, in the above-described greening technology in the decorative pillar structure, the device structure for greening is greatly protruded outside the decorative pillar structure, and the appearance is not good.
In particular, in the case of a decorative pillar structure, a person may pass very close to the decorative pillar, so if a flower pot etc. protrudes outside the decorative pillar, a person will collide and drop the flower pot, or vice versa There is also a risk of injury to the injured person. The water and fertilizer supplied to the flower pots may fall, causing a passing person to feel uncomfortable or staining clothes.

An object of the present invention is to solve the above-mentioned problems of the prior art in a decorative pillar structure of a building as described above,
It is an object of the present invention to make it possible to satisfactorily achieve the effect of greening by plants without having a good appearance and without impairing the surrounding environment.

[0008]

A decorative pillar structure for a building according to the present invention is provided between a core pillar material which is erected on the floor of the building and mainly bears mechanical strength. A decorative face structure having a decorative face material arranged so as to surround the outer periphery of the core pillar material at an interval, wherein the decorative face material having an opening in the surface, the core pillar material and the decorative face material, And a greening board material attached to the inner surface of the decorative surface material, the greening material having a flat box shape with one open side, and an open surface attached to the decorative surface material. A box, a water retention layer filled in the storage box, a coated fiber layer that covers the open surface of the storage box, and a planted in the water retention layer, penetrating the coated fiber layer, passing through the opening of the decorative facing material from the open surface. And a green plant extending to the outer surface.

[Decorative Column] The basic structure of the decorative column can be the same as the structure of the decorative column in a normal building. Examples of the place where the decorative pillars are constructed include an entrance porch, a porch, a veranda, and a garden gazebo. The present invention can also be applied to an electric wire drop column, a columnar rainwater tank, a garden light, and the like. The decorative pillars are erected on the floor of the building and serve to support the roof, eaves, etc., which are the upper structures. In the case of an electric wire drop-in column or the like, there is no upper structure such as a roof, but a function corresponding to a use such as supporting an electric wire is required. In addition, the decorative column is required to be exposed to the outside in the entire periphery or in a large part of the periphery, and to exhibit an external design effect.
The decorative column may be installed independently of a surrounding wall surface or the like, or a part of the decorative column may be connected to a structure such as a wall surface.

The decorative pillar has a core pillar material and a decorative face material. [Pillar material] The pillar material mainly bears the mechanical strength necessary for supporting the above-described upper structure. As the material of the core pillar material, a steel frame material, a shaped steel material, a concrete pillar, a reinforced concrete pillar, or the like is used. The core material may have either a solid structure or a hollow structure. If the core structure has a hollow structure, weight reduction can be achieved while maintaining necessary strength. Electric wires can be passed through the hollow structure, and rainwater can be collected. The cross-sectional shape of the core pillar material may be rectangular, polygonal, circular, elliptical, or another different shape according to the cross-sectional shape of the decorative column as a whole. The cross-sectional shape of the entire decorative pillar and the cross-sectional shape of the core pillar material may be different.

[0011] It is common that one core pillar is provided on one decorative pillar, but a plurality of core pillars can be provided on one decorative pillar. [Decorative face material] The decorative face material is arranged around the outer circumference of the core pillar material with a space between the decorative pillar material and expresses the appearance design of the decorative pillar. As the material of the decorative surface material, a material having surface characteristics such as color, surface texture, unevenness, and pattern that can express a desired external design is used. A material excellent in weather resistance, stain resistance and the like is preferable. Specific materials include metals such as aluminum and stainless steel, synthetic resins, ceramics, glass, inorganic boards, wood, and natural stone boards. A composite material in which a plurality of materials are combined can also be used.

The decorative surface material has an opening in the surface. The opening may have a shape corresponding to the entire surface of the greening board material, or may have a large number of small openings through which stems and roots of the greening plant can pass. In order to form an opening in the decorative surface material, a material such as cutting, punching, and etching may be applied to the material of the decorative surface material to form an opening therethrough. The openings may be provided by combining or knitting linear or bar-shaped materials at intervals. The openings may be provided by connecting the plate members arranged at intervals with a wire or a bar. These structures can be combined.

[0013] The cross-sectional shape of the decorative surface material surrounding the outer periphery of the core pillar material may be similar to the cross-sectional shape of the core pillar material,
The shape may be different from the cross-sectional shape of the core column material. Specifically, rectangles, polygons, circles, ellipses, ovals, and other irregular shapes can be adopted. The core pillar material and the decorative surface material surrounding the outer periphery of the core pillar material may be arranged concentrically, or the core pillar material may be arranged at a position off the center of the decorative surface material. The decorative face material is attached to the core material via bolts and metal fittings. [Green board material] A member for holding a green plant and growing the green plant, and is attached to a decorative surface material having a decorative pillar structure.

The greening board includes a storage box, a water retention layer, a coated fiber layer, and a greening plant. <Storage box> The storage box has a flat box shape with one side open,
It has a shape and a size that can accommodate a water retention layer, a coated fiber layer, and a part of a green plant. As a material of the storage box, a metal such as aluminum or stainless steel, a synthetic resin, or a ceramic is used. It is preferable to use a material having airtightness that does not allow moisture or nutrients held in the water retention layer to leak out. However,
It may have a certain degree of air permeability and moisture permeability. Generally, a rectangular shape such as a square is employed as the planar shape of the storage box, but a polygonal shape such as a hexagon, a circular shape, an elliptical shape, an oval shape, and other irregular shapes can also be employed.

[0015] The housing box may be provided with mounting means for mounting the greening board material to the decorative surface material. As the attachment means, a fastening structure in an ordinary mechanical device such as an insertion hole or a screw hole of an attachment screw, an engagement piece, or a fitting protrusion can be adopted. Mounting by magnetic force using a magnet is also possible. If the attachment means has a detachable structure, it is easy to attach and detach the greening board material to and from the decorative pillar structure. If the mounting means extends outward from the outer peripheral edge of the storage box, the thickness of the greening board does not increase due to the mounting means. <Water retention layer> The water retention layer retains the water and nutrients necessary for the growth of the green plant and supplies it to the green plant, and supports the root of the green plant.

As the material of the water retention layer, various water retention materials used in ordinary plant cultivation can be used. A mat-like material obtained by knitting or accumulating a natural or synthetic fiber material or wire material can be used. Synthetic resin foams can also be used. It is desirable that the water retaining layer has a space that allows the roots of the green plant to freely extend.
The water retaining layer holds the water necessary for the growth of the green plant. Substances necessary for the growth of green plants, such as fertilizers and other nutrients, can be held in the form of an aqueous solution or powder. The culture soil can be supported on a water retention layer. As the water retention layer, a layer holding nutrients and a layer holding moisture can be separately prepared and laminated inside the storage box.

After the greening board material is installed on the decorative face material having the decorative pillar structure, moisture and nutrients can be supplied to the water retaining layer.
For example, moisture or the like can be supplied from the open surface of the storage box to the water retention layer through the coated fiber layer. It is also possible to provide a water absorption hole or a water absorption pipe connected to the water retention layer on the outer wall of the storage box, or to connect a water absorption tube. <Coated fiber layer> The coated fiber layer is disposed inside the storage box on the surface side of the water retention layer, and covers the open surface of the storage box. It also functions to prevent water and nutrients retained in the water retention layer from leaking, and to prevent the water retention layer and greening plants from falling off.

As the material for the coated fiber layer, basically the same material as the material for the water retaining layer can be used. Compared to the water retaining layer, it is possible to use a material having a higher density, a lower water permeability, or a material having different characteristics in accordance with a required function. Since the growth of the green plant is mainly performed in the water retaining layer, the coated fiber layer is less required for the function of growing the green plant. When the green plant grows, it is necessary to set the properties such as the strength and deformability of the coated fiber layer to the extent that the gap between the coated fiber layers can be expanded or pierced and extended to the outer surface. desirable. <Green plants> Normal plants for wall surface greening can be used as long as they can grow and prosper while being held by the greening board. A green plant that can grow with the open surface of the storage box vertical or nearly vertical is preferable. Those that can grow only with water and nutrients held in the water retaining layer are preferable. When the irradiation amount of the sunlight is small or the temperature condition is restricted depending on the installation location of the handrail structure, a green plant that is suitable for those environmental conditions is preferable.

Specific examples of greening plants include lichen plants and succulent plants. Sedum plants are preferred. The green plant can be germinated and grown by planting seeds in the water retaining layer, or seedlings of the green plant that have germinated or grown in advance can be planted in the water retaining layer of the greening board. The greening plants pass through the coated fiber layer from the front of the water retaining layer, grow outside from the open side of the storage box, and prosper on the entire surface of the greening board. It can also extend outward from the outer periphery of the greening board material and spread over the entire surface of the decorative surface material of the decorative pillar structure to which the greening board material is attached, and can prosper.

[Installation of greening board material] The greening board material is arranged in a gap formed between the core pillar material of the decorative column and the decorative surface material, and is attached to the inner surface of the decorative surface material. A mounting structure for a greening board material can be provided in a place where the greening board material is mounted in the decorative surface material. An attachment member corresponding to the attachment member provided in the storage box for the greening board material can be provided in the decorative surface material. Specifically, mounting screw holes and uneven fitting parts in the decorative surface material,
An engagement fitting or the like can be provided. The greening board material may be fixedly attached to the decorative surface material by attaching means such as adhesion or welding, or may be attached or detached as necessary by attaching means such as screwing or fitting. It may be mounted where possible.

The greening board is attached with the open side of the storage box facing the inner side of the decorative facing. Greening plants that prosper from the open surface pass through the opening of the decorative surface material and extend to the outside.
The greening board material can be arranged without gaps on the entire surface of the decorative surface material, or can be partially arranged at intervals. If they are arranged at equal intervals in the vertical and horizontal directions, arranged in a striped pattern, a checkered pattern, a staggered pattern, or the like, and the greening board is arranged according to a certain pattern, the design can be enhanced. With the decorative pillar structure attached to the decorative pillar structure, the decorative pillar structure shows a decorative surface material and a green plant that extends out from the opening of the decorative surface material, and the other structural parts of the green panel material are decorative surfaces. Stored inside the timber. Therefore, the outer diameter of the decorative pillar structure does not increase significantly by attaching the greening board material.

have. The greening plant 40 takes root in the water retaining layer 34,
The roots and stems of the green plant 40 pass through the coated fiber layer 36 and extend from the open surface of the storage box 32 to the outside to prosper. Water retention layer 3
As No. 4, a synthetic fiber mat formed by spirally crimping heat-bondable synthetic fibers and heat-bonding them can be used. Specifically, a CP mat (trade name: manufactured by Nippon Poly Products Co., Ltd.) can be used. This synthetic fiber mat has a large space inside, and a sufficient amount of water retention is secured. Also, the holding power of the green plant 40 is high.

The housing box 32 is provided with mounting pieces 38 projecting outward from the outer peripheral edge on the open surface side at four corners of the housing box 32. The greening board 30 is attached to the decorative surface material 20 by applying the mounting piece 38 to the decorative surface material 24 and screwing it with a screw. Therefore, if the screw is removed, the greening board 30 can be removed or replaced. If the decorative column 20 is attached so that a part of the decorative surface material 24 can be attached and detached, the greening board material 30 attached to the decorative surface material 24 can be attached and detached together with the decorative surface material 24. FIG. 3 shows a state before the greening board 30 is installed on the decorative pillar 20. The greening board material 30 accommodates the water retention layer 34 and the covering fiber layer 36 in the accommodation box 32,
Greening plants 40 are seeded or seeded in the water retaining layer 34.

In this state, the greening board 30 is arranged in a horizontal state, and seeds and seedlings of the greening plant 30 are planted.
After the green plant 30 has grown to a predetermined stage, it is transported to a construction site or a production site for the decorative pillars 20 to make the decorative surface material 2
4 and immediately after the construction, the green plant 30
Is obtained, and the appearance is improved.
In addition, by performing management operations such as water supply and fertilizer supply in a state where the greening board members 30 are horizontally arranged, the growth conditions of the greening plants 40 can be made uniform and appropriate. Green plant 4
The above-mentioned method is effective because proper management is important at an early stage which is important for the growth and prosperity of the zero. The greening plant 40 that has grown or prospered to some extent is then installed on the vertical makeup column 20,
Good overgrowth can be maintained over a long period of time.

Of course, it is also possible to observe the progress of growth and prosperity of the green plant 40 by attaching the green plant 40 to the decorative pillar 20 immediately after sowing or planting the green plant 30 in the green board 30. . In the above-described embodiment, the green panel 30 is attached to the inner surface of the decorative panel 24, so that the green panel 30 is mechanically protected by the decorative panel 24. Damage to the greening board 30, particularly relatively weak portions such as the coated fiber layer 36 and the water retention layer 34, can be prevented by natural forces such as wind and snow or collision of foreign matter. Even if the moisture and nutrients retained in the water retention layer 34 of the greening board 30 leak from the greening board 30, they are less likely to adversely affect the external environment as long as they are inside the decorative surface material 24.

Even if the green plant 40 withers or grows insufficiently, at least the decorative surface material 24 is present on the surface of the decorative column 20, and the internal structure of the green panel 30 is similar to that of the decorative column 20. Since it does not protrude to the outside and is exposed, it is possible to maintain good appearance.

[0029]

The decorative pillar structure of the building according to the present invention is:
By attaching a greening board composed of a storage box, a water retention layer, a coated fiber layer and a greening plant to the inner surface of the decorative surface material, the greening plants can flourish on the outer surface of the decorative pillar, making it easy and effective. Greening can be achieved. Structures other than greening plants do not protrude on the outer surface side of the decorative pillars that perform greening, and in appearance, greening plants are added to the decorative surface material that constitutes the outer surface of the original decorative pillars, The appearance is good and the design is excellent.

Since there is no need to change the structure of the decorative column itself, the same members as those used in a normal decorative column can be used.
It can be additionally installed on the existing makeup column structure,
Construction costs are reduced. It is also possible to replace only the greening board material while keeping the main structure of the decorative pillars or the decorative surface material as it is, so replace the greening board material with poor greening plants with a good greening board material. Thus, it is possible to always maintain the prosperous state of the green plant in a favorable state, or to change the type of the green plant from time to time to change the design and atmosphere. Since traces of removing the greening board material from the decorative surface material also exist on the inner side of the decorative surface material and are hardly noticeable in appearance, it is possible to repeatedly attach and remove the greening board material as necessary.
