A support device (8) for a rib (14) between a floor (18) and a roof (16).
The device includes an expansion means (10) and a pair of resilient
members (12a, 12b). Each of the resilient members (12a, 12b) have a
proximal end (27a, 27b) adapted for connection to the expansion mean (10)
and a distal end (28a, 28b) curved away from the expansion means (10) and
adapted for engagement with the floor (18) and roof (16) respectively.
When the device (8) is positioned towards or against the rib (16) and the
expansion means (10) is activated to drive the members (12a, 12b) apart,
the member's distal ends (28a, 28b) are driven substantially vertically
into engagement with the floor (18) and the roof (16) and a portion of
the device (8) is driven substantially laterally (32) into abutment
against the rib (14).
