Abstract:
PURPOSE: To make it possible to prevent an unit member from being deviated and moved by an external force after the member, which is made of concrete, is connected.
CONSTITUTION: An embedded nut, an embedded bolt or a bolt insertion hole is installed to an unit side surface of each unit member 10 as connectors 11 and 12 so as to connect each of the unit members 10 where two bolt holes 21 and 22 are installed side by side to a connector main body 20 which extends over the connectors 11 and 12 of the adjacent unit members 10. One of them is designed to a long hole extending the parallel direction. An engagement part 23, which comprises projected and recessed parts regularly shaped up, is formed on an outer surface of a main body where its counter part 24, which is projected and recessed and engageable, is formed thereon, thereby binding a bolt 26 and a nut 27 by way of a washer 25 so as to prevent its deviation.
