摘要： A shoring leg comprises an extrusion of aluminum or the like. The leg has a plurality of axially extending slots in its exterior at substantially equi-angularly spaced positions. The wall of the leg defines a substantially circular outer periphery and a hollow interior. The wall is interrupted by slot formations at substantially equi-angularly spaced positions, each slot formation comprising a pair of inwardly directed lips defining a slot therebetween and an inwardly directed web of substantially semi-circular form extending between the points where the lips, on each side of the slot, extend from the said circular wall.

摘要： An isolator includes a load bearing part arranged for deflection against the action of a series of compression springs and tension springs whose axes are pivotal with respect to the axis of deflection. The arrangement is such that the isolator can operate in a range in which an incremental increase in deflection causing compression of springs is such as to result in an incremental decrease in the restoring force of springs resolved along the deflection axis. The tension springs produce an increasing restoring force throughout this range, and the net result is a load/deflection performance in which a region of zero or near zero stiffness of the entire system, along the deflection axis, is provided, bounded by regions of positive stiffness.

摘要： A connector for a shoring system comprises a housing adapted to be mounted on a frame which is to be connected to legs which define the plurality of axially extending channels. The housing slidable receives a bolt. The bolt has a head shaped and dimensioned so that in one orientation axial movement of the bolt may introduce the head through the slot into the channel, and in an alternate orientation the bolt may not be withdrawn from the channel by axial movement. The bolt is associated with means adapted to rotate the bolt and to move the bolt axially relative to the housing.

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.
