As shown in both figures of (b), the ground is excavated along the position where the foundation of the building is constructed, the excavation groove 51 is excavated, and the split chestnut / crushed stone 53 is laid at the bottom thereof. Next, after disposing of concrete on the chestnuts / crushed stones 53 and solidifying it, a plurality of base pieces 5
4 are installed via mortar dumplings 55, respectively. Then, while arranging reinforcing bars (not shown), standing molds 56 are arranged side by side on these base pieces 54, and further the base molds are arranged on both sides of the base piece 54, and then concrete C is hit to cure the concrete C. After that, the foundation forms 52 and 56 were removed to construct the foundation of the building.

I have to. Therefore, when installing the base piece 54, it is necessary to perform leveling of the base piece 54 using the mortar dumpling 55. In addition to this, when the standing form 56 is placed on the base piece 54, a spacer (not shown) is bitten as necessary to level the upper end of the standing form 56, resulting in poor work efficiency. There was a point.

施工方法としてもよい。Further, an excavation groove is excavated on the ground surface which constructs a building foundation, a sheet-shaped receiving member is laid on the inner bottom of the excavation groove, and a self-leveling material is laid on the receiving member to make it horizontal. After forming a reference surface, a base piece on the reference surface,
A construction method of a building foundation in which a standing form and a base form are arranged and concrete is placed between the base form and the standing form may be used.

ために、捨てコンクリートの打設を不要とする。Then, by placing the formwork and the base piece on the reference surface and placing concrete, the leveling of the concrete top is facilitated. In particular, when arranging the base piece, it is possible to install the base piece on the reference plane with the upper end of the base piece kept horizontal without using a mortar dumpling, a spacer or the like. Therefore, the upper edges of the rising formwork are aligned and horizontal, and the level can be easily set by leveling the top end of the placed concrete with a trowel etc. as a guide. The work of placing the self-leveling material on is also unnecessary. Further, since the ground marking can be directly performed on the reference surface, it is not necessary to stretch a water thread for disposing the base piece or the mold. Furthermore, since the self-leveling material prevents the concrete from penetrating into crushed stones and split chestnuts, it is not necessary to place waste concrete.

保持する。When a sheet-shaped receiving member is laid on the inner bottom of the excavation groove, and a self-leveling material is placed in this portion to construct a reference plane, the end portions thereof are formed on both side surfaces of the excavation groove. By making it, it becomes a trough and holds the cast self-leveling material. In this case, even if the inner bottom of the excavation groove is not flat, the self-leveling material can be firmly held firmly and firmly held.
