Abstract
This foundation construction method for a building includes: a first step for creating a foundation base; a second step for installing reinforcement on the foundation base; a third step for installing a frame for creating a foundation to be provided to the foundation base; a fourth step for arranging a plurality of anchors so as to follow the inner periphery of the frame; and a fifth step for placing concrete inside the frame. In the fifth step, the concrete is leveled such that the upper surface of the concrete is the same height as the upper end surface of the frame.
Claims6
A method for constructing a foundation of a building, the foundation including a base having a flat upper surface, the foundation not including any rising portion that rises from the upper surface of the base, the method comprising:
- a first step that forms a foundation ground;
- a second step that installs a reinforcing bar on the foundation ground;
- a third step that installs a formwork, the formwork forming the foundation configured to be arranged on the foundation ground;
- a fourth step that arranges anchors along an inner surface of the formwork;
- and
- a fifth step that places concrete in the formwork,
- wherein:
- the fourth step includes a task of installing an anchor support such that at least one of the anchors is supported by the anchor support, the anchor support including a support portion that supports the at least one of the anchors,
- in the task, the anchor support is fixed to the formwork such that a lower surface of the support portion is located at a higher position than an upper end surface of the formwork,
- the anchor support includes a first anchor support,
- the first anchor support includes:
- a support plate including the support portion, the support plate including a first end and a second end in a width direction that is orthogonal to a longitudinal direction, the support plate being configured to be arranged along the formwork, the first end or the second end being arranged on the formwork;
- a fixing jig that fixes the support plate to the formwork;
- and
- a spacer configured to be arranged between the upper end surface of the formwork and an end of either the first end or the second end of the support plate, the end being arranged on the formwork,
- in the fourth step, the spacer is arranged on the upper end surface of the formwork and the support plate is fixed to the formwork using the fixing jig with the end of the support plate placed on the spacer, and
- in the fifth step, the concrete is leveled such that an upper surface of the concrete is located at the same height as the upper end surface of the formwork.
