FIELD: construction.

SUBSTANCE: pendulum sliding support (1) is designed to separate soil (2) of the base from a structure (3), for instance, in case of base soil (2) movements caused by an earthquake or as an alternative for traditional deformed supports. The support (1) comprises the first support sliding plate (5) with the first concave sliding surface (5'), a support block (4), being in a sliding contact with the first surface (5'), and also the second support plate (6) with the second concave surface (6'), which contacts with the support block (4). The first sliding surface (5') provides at least in one position a stable position of the support block (4) balance, in which it returns independently after deviation caused by exposure to external forces. Antifriction material (9a, 9b) contains plastic with elastic-plastic compensating properties and with low friction coefficient, at the same time plastic has compensating properties, which make it possible to compensate for deviation of 0.5 mm from the specified plane of the specified sliding surface (5').

EFFECT: increased durability, strength and provision of most accurate return of a sliding element into balance position.
