NAILING CONSTRUCTION METHOD FOR REMOVING NAIL

摘要

PURPOSE: A nailing construction method is provided to remove and recycle a nail without obstructing other structure constructions. CONSTITUTION: A spiral bar(1) alternatively combines many sockets(2) and hollow pipes(3). A grout hose(9) is combined with a recessed groove in flanges(7,7') of the socket and inserted into a drilled hole(20). A space(11) among sockets, hollow pipes and hole is filled with grout(12) through the grout hose and grout is hardened to be nailing. The socket installs a stopper to prevent grout from inletting into the socket. After nailing, a nail is easily removed by rotating the spiral bar combined with the sockets and penetrated through the hollow pipe.
