AMELIORATION POUR UN DISPOSITIF D'ETAYAGE.

摘要

A shoring system consists of a number of vertical legs, with a ledger frame between each pair of adjacent legs. The ledger frame comprises an upper horizontally extending member and a lower horizontally extending member. There are vertical side members adjacent the sides of the frame. The horizontal members extend beyond the vertical side members and each horizontal member is provided with terminal connectors adapted to connect the horizontal members to the vertical legs. Consequently the vertical members on the ledger frame are spaced away from the vertical legs.
