SHORING SYSTEM LEDGER FRAME;STUD CONNECTORS

摘要

A shoring system consists of a number of vertical legs 1 with a ledger frame 20 between each pair of adjacent legs. The ledger frame comprises an upper horizontally extending member 21 and a lower horizontally extending member 22 There are vertical side members 23, 24 adjacent the sides of the frame. The horizontal members extend beyond the vertical side members and each horizontal member is provided with terminal connectors 25 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. The connectors preferably comprise headed studs 38 shaped so as to be insertable in a channel in the legs 1 and then rotated (see fig. 8) so that the head engages overhanging walls of the channel. A wedge member 53 with an oblique slot 52 engages in pin 33 in the stud and is used to draw the stud inwardly to tighten the connection.
