Tilt up slab
From Wikipedia, the free encyclopedia
Tilt-up (or tilt up) slab, is the widespread method of pouring concrete on the ground in a rectangular mold, then use of one or more cranes to "right it" and place it as a large load-bearing wall within an architectural structure. Strong, but cheaper than labor-intensive masonry walls, tilt-up slabs can commonly be seen in "big box" commercial architecture everywhere. Larger walls offer the greatest cost savings, along with greatest advantages in speed of construction. An early example of this method is found in the innovative Schindler-Chase House (835 North Kings Road, West Hollywood, California, USA, 90069), finished in 1922. Architect Rudolf Schindler claimed that with the assistance of a small hand-operated crane, just two workmen were needed to raise and attach the tilt-up walls.
