Abstract
For a cable bearing system, preferably I-shaped, bearers arranged vertically at intervals, one behind the other and several brackets fixed horizontally at the sides to the bearers are used, whereby the bearers have, at one or both ends, holding plates which can be fixed in position, to obtain an earthquake-proof design, particularly for use in nuclear power stations, at least two neighboring bearers are braced together to form a stiff elementary unit of the bearing structure, and the holding plates are designed to be fixed in position with the intermediate insertion of spring elements, effective in all directions, and absorber elements, effective in one direction, whereby the spring and absorber elements, retain their function in a minimum range of 268.degree. K. to 470.degree. K. and the bearing layers have a load capacity of 5 kp/cm.sup.2 (approx. 0.5 n/mm.sup.2) at 473.degree. K.
