Abstract

A constraint device (1), adapted for interposition between parts of works, e.g. between two girder members (12, 16) of a viaduct to hold them securely together on the occurrence of such sharp movements as may be brought about by earthquakes, and allow of slow relative movements, as due to thermal expansion, which device has shown to be uncommonly reliable, comprises a cylinder-piston unit (2) having a cylinder (3) wherein a piston (7) defines two oppositely located working chambers (24, 25), a conduit (26) between the chambers (24, 25) provided with a throttle (27), and a gas accumulator (34) formed in the piston (7) and being communicated to one chamber (25) through a passageway (32) provided with a throttle (33).
