DOUBLE T
SLAB : TT
“Double T” or “TT” is a pre-stressed concrete slab which can be casted in varying width from 170-250 centimeters and varying height from 30-102 centimeters. The height of the TT slab is dependent on the amount of reinforcements required. TT slabs with depth between 95-102 will have π (pi) shaped legs to accommodate for additional reinforcements.
Function
Supported by L and Reversed T beams, TT slabs are suitable for the construction of intermediate floors in industrial buildings such as factories, ware houses, low rise offices and parking buildings. In addition, TT slabs can be used as roof structure when topped with insulation and waterproofing membrane. This is particularly useful for buildings that require flat slab roofing such as parking buildings and buildings that may require utilization of roof area. When used as a roof TT slabs can span up to 30 meters without intermediate columns.
