PCT No. PCT/SE81/00291 Sec. 371 Date May 28, 1982 Sec. 102(e) Date May 28, 1982 PCT Filed Oct. 8, 1981 PCT Pub. No. WO82/01388 PCT Pub. Date Apr. 29, 1982.A flexible terminal point, specially for lattice work constructions comprising a tube formed terminal means (5), which is secured to one of the bars (1), and which at its one end (7) receives the other bar (3) in a manner which allows limited flexibility. Through the tubelike terminal means (5) runs one or several tie-rods, by which the terminal means (5) is attached to the other bar, and by which the terminal means can be pretensioned, whereby load changes in the other bar (3) only to a lesser degree cause strain changes in the tie-rod (15) while the major part of the loads in the other bar (3) is taken up by the tube-like terminal means (5) which is set under compression forces. Coupling between terminal means (5) and the movable bar (3) is effected by means of a bearing socket via a rubber pad (13) or spherical surfaces in the terminal means (5) and movable bar (3). The tie-rod (15) 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. |
