Self-supporting framework modular structure

Abstract

A method to provide a self-supporting pre-fabricated structure framework, for the building industry, comprising main uprights ( 3 ) formed by extruded sections having outside a plurality of longitudinal grooves ( 3 ′), in which connecting elements ( 5,6,7 ) are put at predetermined knots. Each connecting element ( 5,6,7 ) has a first portion ( 13 ), that engages and locks into one of the grooves ( 3 ′), and a second portion ( 13 ′) that protrudes from said groove ( 3 ′). The main uprights ( 3 ) are connected to each other through the use of main girders ( 4 ) having outside a plurality of longitudinal grooves ( 4 ′) in which engage said second portions ( 13 ′) of said connecting elements ( 5,6,7 ) engage and are locked. Further uprights ( 14,14 a ) and/or secondary girders ( 15 ) can be connected having the same width of said uprights ( 3 ) and main girders ( 4 ). The application of supporting modular external and inner boards ( 20 ) is provided having inside flanged elements that engage the main uprights ( 3 ) and are connected to said main girders ( 4 ) at the top and the bottom end.
