Lightweight modular building structure - has base truss formed of interchangeable sections with extended tubular sections connected by central web

摘要

The basic section consists of a central web (1) and two tubular sections (2, 3) of varying cross-section. The web (1) can be flat metal piece fixed at the edges to two tubular sections (2, 3). One section (2) can incorporate a lengthwise hole on one of its main surfaces. with bent down edges. The modular section incorporates a base truss with at most six different pieces including the end and intermediate uprights. The adjacent crosswise cross sections of two consecutive sections are equal.
