FIG. 7 is a front view showing a state in which plants are born on the surface of the cast-in-place concrete formwork panel according to Embodiment 1 of the present invention.

In the figure, the cast concrete-integrated formwork panel 10 of the first embodiment is a concrete formwork having a size of 1200 m and a size that facilitates frame work and transportation.
m, a 30 mm-long concrete panel base 11 having an area of 600 mm in length and having a mechanical strength enough to withstand the casting pressure of the concrete to be cast into the formwork; A wood chip 2 obtained by crushing thinned wood in a forest is bonded to one surface of a base 11 with a binder to form a flat panel 12 having a thickness of 30 mm. The area of the cast-in-place concrete formwork panel 10 is standardized to a size that facilitates framing work and transportation as a concrete formwork. , The side is 500 ~
It can be formed as an area having a size of 1200 mm and a length of 500 to 600 mm.

A metal fitting 14 projecting from the back surface of the panel base 11 is connected to a reinforcing bar buried in the center of the panel base 11, and the cast concrete-integrated form panel 1 is connected.
It is used for fixing when stacking 0s or assembling and forming a formwork of a structure by framing. Therefore, it may be continuous in the front and back directions on the paper surface of FIG. 1 or may have a predetermined length.

Next, a method of manufacturing the cast concrete-integrated formwork panel 10 thus configured will be described.

First, as shown in FIG. 3A, a reinforcing member is inserted to form a panel base 11 having a predetermined strength. The panel base 11 manufactured in a block shape is covered with a panel form 30 having the same internal dimensions as the panel base 11 so that the panel base 11 is accommodated therein, with the metal fitting 14 as a lower surface.

Then, a synthetic resin-based adhesive as a binder was applied to the surface of the panel substrate 11, and before the applied binder was solidified, thinned lumber such as cedar and cypress, which had low value as a building material, was crushed. Wood chips 2 obtained by kneading wood chips 2 with a binder as an adhesive made of synthetic resin
Is poured into the upper surface, which is one surface of the panel base 11 surrounded by the panel formwork 30. FIG. 3B shows the state during the pouring.

When the pouring of the wood chips 2 is completed, the surface of the wood chips 2 is usually finished flat. The surface of the decorative panel 12 made of the wood chips 2 does not necessarily have to be flat. However, if necessary, the surface may be flattened by pressing the surface with an iron or the like or pressing with a pressing force of a machine.
Vibration is applied together with the panel base 11 and the panel form 30 to make them flat. When the material is vibrated, and at the same time is breathed by mechanical force and flattened, the wood chips 2 are more closely packed,
The bonding strength with the panel base 11 also increases.

The surface of the decorative panel 12 made of the wood chips 2 does not necessarily have to be flat. For example,
It may be formed as a convex hill. Of course, in this case,
Can be breathed by mechanical force.

Depending on the viscosity of the kneaded binder and the wood chip 2 and the material of the binder, after 30 minutes to 24 hours, the wood chip 2 solidifies to a predetermined strength and can be taken out of the panel form 30. It becomes possible.

As described above, the wood tube 2 is connected to the panel form 30.
The decorative panel 12 is obtained by solidifying the wood chips 2 in a state of being poured onto the panel base 11 surrounded by.

Then, from the panel form 30 to the panel base 1
1 and the hardened wood chip 2, that is, the decorative panel 12 is taken out. FIG. 3 (c) shows the cast concrete integrated form panel 10 according to the present embodiment in a state in which it is taken out. The height of the frame of the panel formwork 30 is set to a thickness obtained by adding the thickness of the panel base 11 and the thickness of the decorative panel 12, that is, the thickness of the cast-in-place concrete integrated formwork panel 10 to 60 mm. ing.

The thickness of the panel base 11 is
Although it depends on the size of the inner reinforcing bar of the panel base 11 and its structure, it has mechanical strength enough to withstand the casting pressure of the concrete to be cast. In this embodiment, the thickness is 30 mm. Decorative panel 12
In this embodiment, the thickness is 30
mm. The thickness of the decorative panel 12 is such that the wood chips 2 and the binder in the decorative panel 12 are deteriorated by sun rays, wind and rain, or decayed by decay or the like.
Is gradually reduced, so that the thickness is set so that plants such as plants and plants can grow on the decorative panel 12 in the meantime.

Further, the decorative panel 12 is formed of a concrete-integrated formwork panel 11 as shown in FIG.
Then, a form of the structure is formed, and concrete is poured into the form to complete the construction. As shown in FIG. 7 described later, plants E are generated on the decorative panel 12 on the surface of the structure. It is to make it.

Next, a method of using the cast-in-place concrete integrated formwork panel according to the first embodiment of the present invention will be described.

As shown in FIG. 4, at a construction site where a structure is to be constructed, a book is provided so as to be opposed to a facing mold 20 called a control panel made of a veneer plate or the like at a predetermined distance. The metal fittings 14 and the connecting tools 23 and the fixing tools 21 so that the surface of the decorative panel 12 of the cast-in-place concrete formwork panel 10 according to the first embodiment is exposed.
The formwork of the predetermined structure is formed by stacking or framing using, for example. In the drawing, a reinforcing bar buried in the center of the cast concrete A is omitted.

Then, as shown in FIG. 5, kneaded cast concrete A is cast into a formwork. Thereafter, when the curing of the cast concrete A is completed, the nut 22 of the fixing tool 21 is removed, and the opposing formwork 20 is removed. Then, the stone and the soil are backfilled to bury the soil to complete the construction of the structure. This state is shown in FIG.

In this way, the cast-in-place concrete formwork panel 10 according to the first embodiment of the present invention becomes a formwork panel that is integrated with the cast-in concrete and forms the surface of the structure. Therefore, there is no need to remove it after using it as a formwork, so dismantling and clearing it are unnecessary,
Of course, no waste material is produced, and the exposed surface of the structure is not concrete but the wood chips 2 on the surface of the decorative panel 12 are exposed. Within a few months after construction, the surface of the decorative panel 12 will rot, become earthy, and become a color that exists in nature. In other words, even during this state from the construction, the surface of the wood chip 2 fixed with the binder is exposed and has a color similar to natural wood skin, so that it hardly dissolves and damages the natural scenery very little. Naturally, after a few months, the surface of the decorative panel 12 will rot and become earthy, so that it becomes a color that exists in the natural world and does not feel uncomfortable.

In addition, while the wood chips 2 and the binder in the decorative panel 12 are deteriorated or decomposed and decayed due to sun rays, wind and rain, etc., the wood chips 2, that is, the decorative panel 12, are removed from surrounding plants and trees. The seed of the plant E that has been dropped or carried by the wind adheres, and the plant E such as a plant grows naturally. FIG. 7 shows the state during the growth. Of course, the seeds (including spores) of the plant E may be directly sown. According to experiments by the inventors, ferns are suitable as the plant E. In the experiment, attachment of moss was confirmed at an early stage.

In this way, after one to three years have passed, the plants E of the same kind as the surrounding plants naturally cover the entire surface of the structure, and the natural landscape is not impaired at all. Even so, it does not cause any discomfort.

Also, since the surface of the structure is not as hard as concrete and wood chips are shown on the main decorative panel 12 or the native plants E, there is no sound reflection,
A sound absorbing effect also occurs. Therefore, the cast concrete-integrated formwork panel 10 produces a reverberation and is difficult.

As described above, the method for manufacturing a cast-in-place concrete formwork panel according to the first embodiment has a predetermined area that can be used as a form for cast-in-place concrete A.

Further, it has a mechanical strength enough to withstand the casting pressure of the casting concrete A, and a concrete panel base 11 integrated with the casting concrete A and the wood chip 2 are joined with a binder to form a flat surface. And the panel base 11
And a decorative panel 12 joined to one surface of the decorative panel.

Therefore, the decorative panel 1 of the cast-in-place concrete formwork panel 10 exposed as the surface of the structure
While the wood chips 2 are decayed due to deterioration or decay, etc., the plant E dropped from the surrounding plants or carried by the wind
The seeds adhere to the decorative panel 12 and grow naturally, and thus naturally cover the surface of the structure, and do not impair the natural landscape.

The decorative panel 12 is made of the wood chip 2
Wood chips 2 kneaded with a binder and a panel form 3
However, the present invention is not limited to this, and a binder may be applied on the panel base 11 and a wood chip may be placed thereon. 2 may be joined to the dispersing panel base 11. Further, the seeds of the plant E may be distributed together with the wood chips 2. Alternatively, the decorative panel 12 may be formed in the same size as the panel base 11 in advance, and joined to the panel base 11 with a binder.

Fourth Embodiment FIG. 10 is a perspective view showing a panel base of a cast-in-place concrete formwork panel according to a fourth embodiment of the present invention. In the drawings, the same reference numerals and symbols as those of the first embodiment denote the same or corresponding components as those of the first embodiment. The description will be omitted, and only the differences will be described.

The difference between the fourth embodiment and the first embodiment is that a large number of columnar holes 1a are formed on the joint surface between the panel base 11 and the decorative panel 12. That is, the panel base 11 is used.

As shown in FIG. 10, using a panel substrate 11 in which holes 1a are regularly formed in a row and a row, the surface formed unevenly by the holes 1a of the panel substrate 11 is used as a joint surface to form a decorative panel. 12 is the cast concrete-integrated formwork panel 10 of the fourth embodiment. In addition, the method of forming the joint surface of the panel base 11 with irregularities is performed using a mold.

As described in the first embodiment, the concrete is cast on the form using the cast concrete-integrated form panel 10 of the fourth embodiment configured as described above. When the structure is constructed by installing, the cast concrete and the cast-in-place concrete integrated formwork panel 10 are integrated, and the surface of the structure is similar to that of the decorative panel 12 as described in the first embodiment. The surface is exposed.

Even if the exposed decorative panel 12 is degraded or decays due to sunlight, wind or rain, or the biodegradability of the binder, the growing plant does not fall off the surface of the structure, The roots and seeds move from the decayed decorative panel 12 which has decayed to the uneven portion which is the hole 1a of the panel base 11 by being held or crawled, and the growth of the plant E does not stop. In particular, in the present embodiment, the bonding area with the decorative panel 12 is increased, so that the bonding strength can be increased.

Further, the panel base 11 is generally not vertical, but is constructed so as to be inclined (see FIG. 6) so that the uneven surface which is the hole 1a becomes the surface (see FIG. 6). Since it is easy to hold water and keep water, it is also possible to supply water to the plants E growing there. Therefore, the mechanical strength between the holes 1a of the panel base 11 is the same even if the holes 1a are formed in a columnar convex shape in order to strengthen the bonding with the decorative panel 12. However, since the water of the native plant E can be secured, it is desirable to use the hole 1a.

By the way, when the present invention is carried out, the hole 1
“a” does not need to be formed regularly in rows and columns, may be random, and may have a tapered or square hole shape.

Fifth Embodiment FIG. 11 is a perspective view showing a panel base of a cast-in-place concrete type form panel according to a fifth embodiment of the present invention. In the figure, the same reference numerals and symbols as those of the above-described fourth embodiment indicate the same or corresponding components as those of the fourth embodiment. The description will be omitted, and only the differences will be described.

The difference between the fifth embodiment and the fourth embodiment is that three groove-shaped portions 1b are formed on the panel base 11 on the joint surface side with the decorative panel 12 described above. That is, the panel base 11 is used.

As shown in FIG. 11, the decorative panel 12 is formed by using the panel base 11 in which the groove-shaped portions 1b are formed in a horizontal row, and using the surface of the panel base 11 formed by the groove-shaped portions 1b as the uneven surface as a bonding surface. Is the cast-in-place concrete integrated formwork panel 10 of the fifth embodiment. The method of forming the groove-shaped portion 1b on the bonding surface of the panel base 11 is performed using a mold.

The cast concrete-integrated formwork panel 10 of the fifth embodiment constructed as described above is constructed by casting cast concrete as described in the first embodiment. When the object is constructed, the cast concrete and the cast concrete-integrated formwork panel 10 are integrated, and the surface of the structure exposes the surface of the decorative panel 12 as described in the first embodiment.

Even if the exposed decorative panel 12 is deteriorated or decays due to sunlight rays, wind and rain, or the biodegradability of the binder, the growing plant E does not fall from the surface of the structure. The roots and seeds move from the decayed decorative panel 12 by holding or crawling from the rotten decorative panel 12 to the concave-convex portion of the panel base 11, and the growth of the plant E does not stop. In addition, since the bonding area with the decorative panel 12 is increased, the bonding strength can be increased.

In addition, the panel substrate 11 is not generally vertical, but is inclined so that the uneven surface becomes the surface (see FIG. 6).
The groove-like portion 1 which is the concave portion
