A flexible terminal point, especially for lattice work constructions comprising a tube formed terminal means, which is secured to the disc formed or shell formed bars, and which at its one end receives the bar in a manner which allows limited flexibility. Through the tube-like terminal means runs one or several tie-rods, by which the terminal means is attached to the bar, and by which the terminal means can be pretensioned, whereby load changes in the bar only to a lesser degree cause strain changes in the tie-rod while the major part of the loads in the bar is taken up by the tubelike terminal means which is set under compression forces. Coupling between terminal means and the movable bar is effected by means of a bearing socket via a rubber pad or spherical surfaces in the terminal means and movable bar. The tie-rod can be formed as one or several tie-rods, steel cables, wires or such, which can be tensioned and locked by known methods for pretensioned constructions. |
