By placing horizontal rebars in a series of placement grooves or insertion holes according to the foundation mold and filling mortar in the placement grooves or insertion holes, the connecting horizontal rebars are embedded to integrate the continuous state of the precast foundation mold, and the precast foundation mold This is a method in which only the continuous standing wall of the precast foundation type is exposed by covering the base plate with soil or concrete. Note that the precast foundation molds adjacent to each other may be connected by filling the vertical recesses of the joints with reinforcing bar mortar.

The precast foundation mold used for the precast foundation mold is a precast foundation mold in which a standing wall portion is integrally formed of reinforced concrete in an upward direction at the center of a wide base plate portion. Is a flat cross, a flat T-shape,
A precast foundation die having a plane L shape and a plane straight shape is provided, and a vertical recess is formed at the end of the standing wall portion, which is cut down to the base plate portion. In addition, you may provide the arrangement | positioning groove | channel or the insertion hole of the horizontal reinforcing bar along a longitudinal direction in both or any one of the base plate part and standing wall part of each precast foundation type | mold.

[0006]

In the method invention, the precast base molds are arranged in sequence on the cloth base line, and the adjacent precast base molds are connected to each other by filling the vertical recesses of the joints with reinforcing bar mortar, or at the same time as the connection, continuous arrangement of the precast base molds. By arranging the horizontal rebars in the arrangement groove or insertion hole of the precast foundation mold that is a series of the above, and by filling the mortar in the arrangement groove or insertion hole, the connecting horizontal rebars are embedded and the continuous state of the precast foundation mold is integrated. It is. Then, the base plate portion of the precast foundation mold is covered with soil or concrete to expose only the continuous standing wall portion of the precast foundation mold to form a cloth foundation.

Further, the precast foundation mold is provided with each precast foundation mold in which the base plate portion and the standing wall portion are formed into a plane cross shape, a plane T shape, a plane L shape, and a plane straight line shape.
Since each is a wide base plate part, its installation is stable, and by providing vertical recesses up to the base plate part at the end of the standing wall part, adjacent precast foundation molds can be connected by reinforced mortar filling. Of.

[0008] In addition, if a pre-cast foundation die continuous arrangement is provided by providing a transverse reinforcing bar arrangement groove or insertion hole along the longitudinal direction in the base plate portion and / or the standing wall portion of each pre-cast foundation die. By arranging the horizontal reinforcing bars in the series of arrangement grooves or insertion holes and filling mortar in the arrangement grooves or insertion holes, the connecting horizontal reinforcing bars can be embedded and the continuous state of the precast foundation mold can be integrated, and a solid cloth It can be the basis.
