ABSTRACT:
A method of erecting multi-story buildings by joining spaced elongated vertical columns of concrete. The method comprises providing a screw threaded metal socket in the face of each column to be connected. The socket of one column has a thread opposite in direction to that of the socket in the other column. One column is disposed over the other with the mouth of the sockets aligned. An elongated coupling, having an external threaded portion at each end, with the thread at one portion being opposite to the direction of the thread in the other portion and including an intermediate portion having a grip surface, is disposed between the sockets and rotated via its grip surface while the columns are spaced so as to simultaneously screw the threaded portions into the corresponding sockets by a sufficient distance to adjust the spacing between the sockets such that the upper column remains spaced above the lower column but supported thereon by the connection between the sockets and the coupling, with the spacing between the sockets being defined by the length of the intermediate portion of the coupling.
