METHOD OF MOUNTING PLATE BODY ON CONCRETE STRUCTURE
Document Type and Number:
Japanese Patent JP3022514
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent adhesiveness and tightness between a plate body and impregnant from being impaired by eliminating the need for extracting bolts tightening the plate body to a concrete structure when a retaining device is removed.
SOLUTION: A plate body 2 obtained by installing, on a counter bolt 3, an elastic retaining collar 6 comprising a countersunk bolt hole, a conical cylindrical part 6a along the slanted surface of the countersunk bolt, and a cylindrical part 6c having a retaining part 6b arresting the countersunk bolt hole end part from the inner surface of the plate body 2 is positioned on a structure 1 with the countersunk bolt 3 aligned with an anchor 5. The countersunk bolt 3 obtained by forming a female screw 3a is inserted into the inner surface of an elastic retaining collar 6 so as to screw the male screw of the countersunk bolt 3 to the female screw 3a of the anchor 5 buried in the structure 1.
