A support for shoring forms at different levels comprises one or more sections each having spaced pairs of vertical legs (35, 37), which are extensible at upper and lower ends thereof, and horizontal beams (135) supported near the top thereof. In one embodiment, the horizontal beams (135) support a first form at one level, and legs (94) extending upwardly past the beams (135) support a second form at a second level. The upper ends of these legs (94) can be retracted and extended without interfering with the forms supported by the beams (135). In another embodiment, Fig. 13 (not shown), beams carry removable blocks (165) that support the second form. <IMAGE> |
