Tension anchor driven into ground - has shock absorber which absorbs energy when anchor tension member fractures and supports load

摘要

A spring or hydraulic shock absorber (10, 20) is used to absorb energy after the anchor is fractured. The anchor has a clamping head (5) clamped against the foundation wall (7). The anchor has an internal helical compression spring (11). This spring is loaded by a flange (12) of holding tube (13) held on the anchor head plate (6). In case of fracture of the anchor tension rod the spring will absorb the energy. Alternatively a piston and cylinder filled with a plastic medium can be used. This medium is forced through a perforation for energy absorption.
