Beam and joist assembly

Abstract

The present invention is an I beam including a web, a top flange and a bottom flange. The flanges are parallel with the web extending therebetween so as to form spaces, at both sides of the web. Notches are formed in the top and bottom flanges of a joist of a height for fitment into the space of beam. A plate with at least four holes equi-spaced top and bottom is welded to each end of the stock length supplied beam, perpendicular to the web. The invention includes the method for providing a beam to beam connection, wherein the top and bottom flanges of beams are notched such that a first end is disposed between the top and bottom flanges of the first beam, and wherein the second beam web includes a connection plate to attach to the first beam web via fasteners.
