Plug-up structural system of cross-linked beams uses angle profiles as beams to form parallelograms from facing leg sides all linked by transverse connectors.

摘要

The longitudinal beams (4) consist of two-leg angle profiles whose one or both profile angle legs (16,20) form a parallelogram section (46,48). The other two legs are also in parallelogram section with fitted rectangle (40). The angle legs mirror one another to give a common parallelogram side which terminates at the angle apex (22). The transverse connectors (10,12) have facing sides parallel to the adjoining sides of the beam angle legs as fitted with anchoring elements to engage the corresponding elements on the respective angle legs, thus joining connectors and angle legs. The length of the connectors so relates to that of the angle legs that the tangent (64) to the apex of the beam normal to the lengthways direction of the support structure (2) intersects the second angle leg of the following beam.
