IPC: E04C5/16
Filed: 2002-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To previously assemble a reinforcement structural body without using any welding means.  <P>SOLUTION: The shape of this assembly formed by assembling multiple reinforcement bars together is maintained by forming a form block also serving as a spacer.
