Self-supporting and insulating lightweight slab for the construction of a unidirectional reinforcement

摘要

The panel (1) is made from two components - an inner member (2) of solid expanded polystyrene with trapezoid-section grooves (5) in its under-surface for electrical wiring, and an outer member (6) of concrete reinforced with steel rods (7) covering the top and sides of the inner member. The outer lateral surfaces of the outer member have lengthwise channels (8) and recesses (9) to provide keys for a covering layer of concrete.
