DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving formwork method for constructing a concrete wall using a driving formwork, and a wall constructed by this method.

[0002]

2. Description of the Related Art As a method of constructing a concrete wall, a method of assembling a formwork and casting concrete on the back side of the formwork is generally used. Conventionally, a wooden board (plywood) form has often been used as this form, but a driving form made of concrete or the like is becoming widespread for saving resources. This formwork is assembled on site in the same manner as a normal formwork, and concrete is cast on the back side.
In the case of plywood formwork, demolding is performed after the concrete has hardened, but in the case of driven formwork, it is left as is,
The surface of the concrete wall is formed by the driving formwork.

[0003]

Most of the conventional driving formwork is made of concrete, and the surface of the constructed wall becomes the concrete surface of the driving formwork, which is not beautiful.

[0004] It is an object of the present invention to provide a wall surface which is excellent in aesthetic appearance and a driving formwork method by which this wall can be easily constructed.

In a driving formwork method for placing concrete on the back side of a frame, the driving form comprises siding having a surface subjected to cosmetic treatment.

According to the driving formwork method of the present invention (claim 2), a driving form is installed along a surface to be constructed with a driving form holding member, and concrete is placed on the back side of the driving form. In the driving formwork method to be cast, the driving formwork is a tile locking plate having a tile locking portion on a front surface, and the tile is locked to the tile locking portion after the concrete casting, It is characterized by a tiled wall.

The wall according to the present invention is constructed by this driving formwork method.

The surface of the wall provided by the present invention is made of a siding or a tile-finished surface which has been subjected to a cosmetic treatment, so that the wall has an excellent appearance. In addition, since this wall is constructed using a driving formwork, construction work is also easy.

[0009] Even in the case of tile finishing (claim 2), since the driving formwork itself has the tile locking portion, it can be constructed so that the tile is hooked on the tile locking portion. Also, tile attaching work can be easily performed.

In the present invention, the heat insulating plate may be held and distributed on the back side of the driving form by a holding member for holding the driving form. In this case, the heat insulating wall can be easily constructed. The heat insulating plate also plays a role in protecting the driving formwork during construction.

In the present invention, the driving form has an engaging portion of the driving form holding member and a concealing portion of the driving form holding member at an edge thereof. The leading end side of the driven form holding member may be engaged with the engaging portion, and the leading end side of the driven form holding member may be covered and hidden by a concealing portion of an adjacent driven form form. 4). By doing so, the tip side of the driving form holding member is not exposed at all to the wall surface, and a very beautiful appearance can be obtained. Further, when the driving form holding member is made of metal, by not exposing the metal tip,
The deterioration such as corrosion is also prevented.
