Load bearing support assembly for e.g. bridge structure

摘要

The load bearing support comprises a pair of pressure distribution pads (2) separated by an elastomer cushion (3). The force distribution across the upper pressure pad is shown by the graph (5) and is measured by a strain gauge (6) cemented into a cavity in the pad (2) contoured to provide a flexible diaphragm (9) which is able to flex under load. The strain gauge signals are routed via the leads (7) to the instrument (10) for periodic checking or continuous display.
