Modular units are connected to each other with the aid of recesses provided in the edges of the modular units and with the aid of clamping bolts each carrying two nuts and a clamping nut in a mirror-symmetrical arrangement relative to a plane passing centrally through the clamping nut and perpendicularly to the longitudinal axis of the clamping bolt. The recesses are correspondingly dimensioned and located so that two sets of recesses in a mirror-symmetrical arrangement can receive the clamping bolt with its nuts. A clamping bolt has oppositely threaded ends so that the rotation of the bolt in one direciton tightens both nuts and rotation in the opposite directions loosens the nuts. |
