Abstract
A truss frame for a bridge and/or support includes two elongated, parallel longitudinally-extending post pipes having an outer circumference; two parallel crossbars extending perpendicularly to the post pipes; and a length-adjustable elongated diagonal element. The parts are hingedly and detachably bolted to one other. Two parallel connecting plates secured near each post pipe end extend away from one another on a common, imaginary plane containing the post pipe and crossbar longitudinal axes. Each crossbar and diagonal element has opposite ends hingedly and detachably bolted to a connecting plate. At least two rosettes are welded to each post pipe at a distance from one another corresponding to an integer multiple of a module scaffold modular size. A connecting body is welded to the connecting plate near at least two post pipe ends associated with the same crossbar and surrounds the respective post pipe outer circumference.
