Abstract
In a square array with a modulus (M), the plug-in building blocks of the building set have protruding connecting pins (1) and corresponding mating connecting sockets. In order that bendproof trusses can also be built, the building set has single-row connecting bars (34) with two terminal pins (35), whose spacing from one another amounts to .sqroot.2 times an integral multiple of the modulus (M), and girder elements (10), which at two bordering sides faces (13, 14) each have a single row of pins with modular spacing and parallel to these side faces each have a projection (19) set back by the thickness of the connecting bar (34). In this way, stable, aesthetically appealing trussings can be built with the building set.
