[0012]

As described above, the present invention provides a precast concrete foundation having a pattern on the surface facing the end faces at an interval, and a precast concrete foundation disposed between the front end portions of adjacent precast concrete foundations and having a back surface. Patterned concrete template with raised legs to enhance adhesion to concrete, and filled with gaps between the end faces of the precast concrete foundation and fixedly integrated with the end face of the opposing precast concrete foundation and patterned concrete The back side of the formwork is fixedly integrated with the connecting base part which is constructed by concrete casting in which the legs are buried. On the front side, the pattern of the precast concrete foundation on both sides and the pattern of the concrete formwork with the pattern therebetween. With this, the entire surface of the foundation becomes a patterned surface, and the back surface of the connection Since the concrete surface of the trace where the frame was removed is exposed, the main body of the foundation can be composed of a precast concrete foundation and a connecting foundation formed by concrete filled in the space between the precast concrete foundation. Therefore, compared to the case where the whole is formed by cast-in-place concrete, the workability is excellent, the construction period can be shortened, and the industrialization rate can be made into a factory. In the case where the main body of the foundation is composed of a precast concrete foundation and a connecting foundation formed by concrete filled in the space between the precast concrete foundation and the surface of the precast foundation formed at the factory, and formed by cast-in-place concrete The surface of the connecting base has an uncomfortable appearance and impairs the appearance of the base. However, in the present invention, the pattern of the surface of the precast concrete foundation and the pattern of the surface of the concrete template that is arranged and left on the surface side of the connection foundation portion are in a state in which the surface of the foundation is patterned. Although it can be said that the foundation can be a foundation with a pattern on the entire surface and the outer surface of the connecting foundation is covered with a patterned concrete formwork that remains even after concrete is cast, When the connecting foundation is formed by assembling the formwork using concrete and pouring concrete, the concrete of the connecting foundation is firmly attached to the legs that are integrally projected on the back of the patterned concrete formwork, When leaving the concrete formwork as a part of the foundation surface, it can be firmly fixed,
There is no danger of the patterned concrete template coming off. Moreover, on the back side of the connecting foundation, the concrete surface where the back-side formwork was removed is exposed. In this way, the surface formwork is fixedly integrated with the connecting base as a foundation pattern using patterned concrete. The backside formwork can be removed and reused as a formwork, and since it is on the backside of the foundation, even if the backside formwork is removed for reuse, it can be used as a precast concrete foundation. The uncomfortable appearance of the connecting foundation with the exposed portion of the concrete surface is not seen from the outside, and therefore, there is no problem even if the back mold is removed for reuse. Furthermore, a linking group
On the back side of the foundation, concrete is removed after removing the back side formwork.
