Document Type and Number:
WIPO Patent Application WO/2007/083428
Kind Code:
A1
Abstract:
A reinforcing-bar engagement device that can be easily engaged with a position
relatively far from an end of a reinforcing bar and exhibits strong engagement
force relative to the reinforcing bar. The reinforcing bar (10) has a body member
(11) having a through-hole (11a) in which the reinforcing bar is insertable and
also has a pair of fitting members (12) fitted between the reinforcing bar inserted
in the through-hole (11a) and the inner peripheral surface of the through-hole
(11a). The inner peripheral surface (11b) of the through-hole (11a) is of a funnel
shape whose diameter is reduced in the direction of the axis (C). A female screw-thread
section (12a) with which the reinforcing bar engages is formed on the inner peripheral
surface of the fitting member (12). The outer peripheral surface (12b) of the
fitting member (12) is a conical surface that is in surface contact with the inner
peripheral surface (11b) of the body member (11). On the outer periphery of the
body member (11) are provided a substantially circular tube-like insertion
section (11c) and a flange section (11d) having a larger diameter than the insertion
section (11c). The fitting member (12) has a slit (12c) in the direction of the
axis (C) of the through-hole (11a).
