PLATE MEMBER FOR FOUNDATION

PROBLEM TO BE SOLVED: To provide a construction member for foundation which can solve inclination or instability of a building caused by irregularity on the upper face of the foundation supporting the building and can realize smooth execution of the foundation part. SOLUTION: There is irregularity on an upper face 10a of a crest plate for foundation 10, while there is irregularity on a lower face 10b. The crest plate 10 is installed on a foundation 80 so that the lower face 10b is brought into close contact with an upper face (crest 80a) of the foundation 80, and the upper face 10a lies horizontally when the foundation 80 is in the middle of hardening. As a result, after the foundation 80 is hardened, there is no inclination or instability of a building. At that time, as the crest 80a is deformed according to the irregularity of the lower face 10b and the foundation 80 is engaged with the crest plate 10, the crest plate 10 is stabled rather than the case where there is no irregularity on the lower face 10b. Moreover, compared to the case where the irregularity of the crest 80a is formed by mortar or covered by a leveler, no time is needed to wait for drying of mortar or leveler, which reduces work time.
