Title:
PRECAST-CONCRETE FOUNDATION BLOCK
Document Type and Number:
Japanese Patent JP3096811
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the requirement of time for the installation of forms by forming an opening section for bolting in the irreducible minimum of a demand in bolting on the front side placed on the inside in an indentation and mounting a vertical wall at a rear on the rear side placed on the outside.
SOLUTION: Stepped sections 2A1, 2A1 for filling mortar for preventing displacement are formed to the foundation block 1, and vertical connecting plates 3B, 3B are set up into indentations 3A, 3A. Consequently, when the foundation blocks 1 are arranged so as to be coupled, the mutual stepped sections 2A1, 2A1 or the mutual indentations 3A, 3A are abutted, and opening sections for joints are formed. Connecting works by bolts are conducted by utilizing the opening sections for the joints. Opening sections 3C for bolting in the irreducible minimum of a demand in bolting are formed on the front sides placed on the insides in the indentations 3A, 3A, and vertical walls 3A2 at rears are installed on the rear sides placed on the outside. Accordingly, forms to the opening sections for the joints are formed only in bolting sections, and the time for the completion of foundation setting can be shortened and cost reduced.
