PURPOSE:To increase the strength of cement mortar by a method in which chain links are set on a concrete foundation, a level-regulated base plate is set on the chain links, and cement mortar is placed between the base plate and the foundation. CONSTITUTION:A chain link 11 for reinforcing cement mortar is set on a concrete foundation 3, and a base plate 6 is set at a given interval between the base 6 and the concrete foundation face 3a. In this case, the regulation of the level is made through a spacer by fixing the spacer to the place where the level is to be regulated by clamping a nut 9 screwed with an anchor bolt 1. Afterwards, a non- shrink cement mortar 10 is poured between the base plate 6 and the foundation concrete 2. Since the chain link 11 is buried in the cement mortar 10, the strength of the mortar 10 is increased and the foundation which can sufficiently withstand earthquake, etc., for spherical tank, etc., can thus be constructed. |
