Abstract: A frame structure, especially for a portable bridge, which comprises at least one pair of struts to be interconnected and equipped with coupling members having such a profile that the coupling members when positively engaging each other permit a pivoting in which the coupling members are able to convey forces in all directions between the two struts. A pivoting back of one strut relative to the other strut from the coupling position is prevented by additional coupling elements.
