DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a precast concrete formwork (hereinafter, abbreviated as PC formwork) capable of fixing a planter for planting on the outer wall of a structure.

[0002]

2. Description of the Related Art In the case of concrete retaining walls used for earth retaining and the like, the surface thereof is often exposed to concrete. On the other hand, the exterior walls of concrete buildings are often decorated with exterior wall finishing materials, such as tiles and paints, in order to avoid tasteless and dry designs due to exposed concrete.

Recently, plants have been placed on the surface of a concrete retaining wall or on the outer wall of a concrete structure to provide moisture. Such planting can be performed easily and inexpensively by installing a planter on the outer wall of the concrete structure. Thus, the contrast between the inorganic concrete wall surface and the greenery by planting gives the structure a design-like appearance, and can create a city space in harmony with nature.

[0004]

However, the work of forming the bolt holes for mounting the planter on the concrete wall surface is troublesome, and in order to avoid this, it is conceivable to install a metal fitting for mounting the planter before placing the concrete. However, it is necessary to firmly fix the hardware so that the hardware does not shift during concrete placement. Even if the planters are mounted after such troublesome work, other maintenance such as watering and fertilization must be performed for each planter.

Accordingly, an object of the present invention is to provide a PC-made formwork which can be easily planted on the outer wall of a concrete structure and can be easily maintained thereafter.

[0006]

In order to achieve the above object, the present invention relates to a precast concrete formwork in which concrete is cast on the back side and is buried.
A water pipe is provided on the back side, a plurality of water holes are communicated with the water pipe and penetrate the back side and the front side, and a planter is mounted at a position surrounding the water holes on the front side. It is characterized in that fittings are buried integrally.

Further, according to the present invention, a water supply hole communicating with the water pipe is opened at a position above each of the water holes.
At the position surrounding the water supply hole on the surface side of the concrete formwork, a fitting for mounting a water supply tank can be integrally embedded.

[0008]

In the above construction, the concrete retaining wall or the outer wall of the concrete structure is formed by integrating the PC-made formwork into the cast concrete as a discarded formwork. Therefore, after the construction, the planter is fixed to the surface of the PC-made form via the mounting bracket, and the inside is filled with soil and planted, or a planter planted in advance is attached.

The inside of the planter communicates with a water pipe through a water passage hole, and water, fertilizer diluted in water, and the like are supplied through the water pipe. If a water supply tank communicating with the water pipe is arranged together with the planter, water is supplied from this to each planter through the water pipe.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIGS. 1 to 4 show an embodiment in which a retaining wall is constructed by a PC formwork method according to a preferred embodiment of the present invention and a PC formwork method using the formwork as a waste formwork. In the drawing, a PC-made mold 1 is used for a horizontally long discarded mold, and a substantially L-shaped water guide pipe 2 having a cup-shaped cross section is integrated on the back side thereof via a packing (not shown). And a plurality of water holes 3 communicating with the water pipe 2 and penetrating the inside and outside of the PC mold 1 are opened in a horizontal line, and each water hole 3 on the surface side of the PC mold 1 is closed. Mounting bolts 4 are integrally embedded above and below the enclosing position, and a plurality of planters 5 are fixed to the surface of the PC-made form 1 via the mounting bolts 4.

Further, at a position above each water passage hole 3, P
A water supply hole 6 communicating with the water guide pipe 2 is formed through the C-shaped frame 1, and mounting bolts 4 are similarly embedded integrally above and below a position surrounding the water supply hole 6, and each of the bolts 4 is interposed therebetween. The water tank 7 is attached.

The planter 5 has a top surface opened and has a hole communicating with the water passage hole 3 on the back surface in contact with the surface of the PC-made frame 1, and a plastic material having a lattice portion for drainage formed at the bottom. A mounting flange 5a for contacting the PC-made form 1 is formed around the back of the container, and the bolt 4 is inserted through a bolt hole opened in the container. As shown in FIG. 2, the nut 8 is fixed by tightening.

The water supply tank 7 is also formed in the same shape as the above-mentioned planter, but the bottom face is closed and the bolt is inserted through a bolt hole of a flange 7 a formed around the rear face, and is fixed by a nut 8. It has become.

In order to construct a retaining wall by using the PC formwork 1 having the above-described configuration, the PC formwork 1 is arranged vertically and horizontally according to the height and width of the corresponding retaining wall. After that, if concrete C is cast on the back surface as shown in FIGS. 2 and 3, the PC-made form 1 and the retaining wall made of concrete C integrated on the back surface thereof are completed. In addition, PC form 1
If you embed the dowel on the concrete casting side of
The integrity of the form 1 and the concrete C can be improved.

In this case, not only the PC form 1 but also
As shown in FIG. 4, an appropriate combination can be selected according to the design design, such as a combination with a conventional PC-made frame having the same vertical and horizontal dimensions and formed in a flat plate shape.

After the above construction is completed, the planter 5
And the water tank 7 is fixed to the surface of the PC-made form 1, and after fixing, the planter 5 is filled with soil 9 and planted with flowers, flowers or other plants 10, or a planter on which the plants 10 have been planted in advance. By fixing 5, the front surface of the retaining wall can be occupied by the planting 10 as shown in FIG. 4, and after a predetermined period, the wall surface is concealed according to the growth of the planting 10, and a greened surface is formed. . The planting plan is implemented by selecting plant types according to the sunshine and temperature of the retaining wall, the allowable volume of each planter 5, the planting time, the surrounding environment, etc., and the replacement of the planting is performed for each planting or each planter 5. be able to.

If the water tank 7 is filled with water or fertilizer diluted with water, the water or fertilizer stored in the water tank 7 is supplied from the water supply hole 6 to the water supply pipe 2, the water supply hole 3, and the inside of each planter 5. Alternatively, fertilization is performed, and labor for water supply and fertilization to the individual planters 5 can be omitted.

The shape and size of the planter 5 and the water supply tank 7 in the embodiment, and the number of them to be attached to the PC formwork 1 should be appropriately set according to the design design of the corresponding retaining wall. It is not limited to the shape and the number of the illustrated example. In addition, the water supply tank 7 is not always necessary.
A method of piping on the back surface of the C-made mold 1 can also be implemented. In this case, collective water supply and fertilization can be performed on each planter 5 over the entire wall surface.

Further, in the above embodiment, the case where the present invention is applied to the PC formwork method has been described, but it is needless to say that the present invention can be applied to a PC decorative panel used for an outer wall of a building or the like.
In this case as well, it is possible to obtain a building having an appearance that is in harmony with the planting that is not found in a conventional building.

[0021]

In the PC mold according to the present invention described in detail above, the planter is fixed to the surface of the PC mold via the mounting bracket, and the inside is filled with soil and plants are planted. ,
Alternatively, the planting is completed only by attaching the planted planter, so that the planter can be easily and accurately attached to the outer wall of the structure.

Since the inside of the planter communicates with the water pipe through a water hole, and water or fertilizer diluted in water is supplied through the water pipe, maintenance of planting is easy,
In particular, if a water supply tank communicating with the water conduit is arranged together with the planter, water supply or fertilization is performed from here to each planter, and maintenance can be reduced.
