Title:
EXPANDING-TYPE ANCHOR AND EXPANDING MEMBER USED THEREIN
Document Type and Number:
WIPO Patent Application WO/2018/159697
Kind Code:
A1
Abstract:
This anchor is a split-tip type of anchor in which a slit 2 opens to a distal end surface 3a of an expanding part 3, and the expanding part 3 expands in diameter due to balls 4 pushed by a bolt 6. The inner peripheral surface of the expanding part 3 is straight. Therefore, the entire expanding part 3 expands in diameter straightly throughout a wide range. Because the entire expanding part 3 expands in diameter, protruding (or wedging) in a lower hole 10 is satisfactory. As a result, high pull-out resistance is exhibited.
