<p>The invention is concerned with a modular prefabricated portal for the erection of buildings. The portal comprises a pillar or abutment portion (20) and a stringer portion (30) which extends cantilever fashion in a substantially normal direction to the abutment portion to provide a manufactured article having, for example an L-, U-, T-, or TT-like or other comparable shapes. The pillar portion (20) has, at one end, two lugs (50) forming an extension of the abutment portion, whereas at the other end thereof, two lug accommodating sockets (66) are provided. Such sockets advantageously comprise either grooves or offsets (66). Bounded between the lugs (50), at one end, and the sockets (66), at the other end of the abutment, is a respective abutting surface (40) for dry resting the portal onto an underlying portal wherewith it is engageable by insertion of the lugs (50) on the one into the the receiving sockets on the other.</p> |
