Assembly nodes for three-dimensional framework

摘要

Assembly node for three-dimensional structure. This invention is characterised by: 1. assembling the three-dimensional structure bars by clamping between the faces of two gussets and the superimposed octagonal plates; 2. assembling the purlin-support core in the slide made by the assembly described in 1. This assembly node is produced by means of: a. two octagonal plates 2, which are superimposed and have an axial hole of square cross-section; b. four gussets 1 with a frustoconical vertical ridge; c. a slide 3 of square cross-section. This invention, by extremely simplifying the in situ assembly of three-dimensional structures further solves the problem posed by the adjustment of the heights of purlins and the fixing of their supports (slides). <IMAGE>
