ABSTRACT OF THE DISCLOSURE The invention relates to a joint connection for girders having more than two members connected in a joint, in particular for steel structures. The members are formed as circular pipes and the ends of the circular pipes converging in a joint are attached to one each joint element by means of screw connections arranged in the axis of the pipe. The ends of the pipes, without reduction of their cross section and flexural strength, are provided with an external thread whose core diameter is at least equal to the outer diameter of the circular pipes. On this external thread, a union nut slidable over the circular pipe is screwable by means of its internal thread and the union nut can also be screwed down on the joint element. The joint elements are preferably hollow and formed with openings extending along the axes of the adjacent circular pipes. It is possible to provide a girder which is filled with a liquid such as water with which it communciates via the joint elements and is connected to a liquid cycle.
