Abstract

This invention relates to semi-rigid inflatable spanning members which are used for bridging purposes particularly for laying down temporary bridges over gaps in open terrain, or over a watercourse. In the prior art these spanning members are constituted by a plurality of inflatable members housed within an envelope above which are arranged rigid plates: these plates are connected together end to end so as to form an arched bearing surface. In accordance with the invention, the envelope is bordered by a cable which engages laterally in channels provided at either side of the rigid plates and this cable is held in place by a suitable locking means.
