PURPOSE:To measure stresses accurately, by fixing a diaphragm type stress gage beforehand with a concrete block, curing the block approximately at a specified temp. and embedding such block in concrete. CONSTITUTION:A diaphragm type stress gage 7 is beforehand embedded and held in a concrete block 8. Mortar is poured in the block 8 and the block is formed at the temp. which is kept constant during setting by underwater curing or the like, so that no abnormal stresses are generated at the boundary between a pressure receiving surface 2 and the concrete. In using the block 8 wherein such gage 7 is fixed, the block is installed in the measuring position in the form of a structure, and the concrete for forming the structure is placed thereon, whereby the block is formed integrally with the structural concrete. The formation of gap, between the pressure receiving surface and the concrete is thus eliminated and the accurate measurement is made possible. |
