Abstract

A joint element for a pneumatic structural element. The joint element includes a sleeve, a compression member, two tension members and two spherical caps. In each case one joint element is fitted for the spherical caps. The joint elements serve for introducing tensile and compressive forces, in a manner free of bending moments, into the pneumatic structural element. The joint element has holes for fastening the compression member with a screw, on the one hand, and holes for accommodating the tension members, on the other hand. The symmetrical arrangement of the holes ensures that the vectors of bearing forces and of the tensile and compressive forces in the joint element added together give zero and, furthermore, the bending moments occur symmetrically in relation to the compression members. Configuring the joint element as a plate ensures that torques are neither introduced from the outside nor diverted to the outside.
