Abstract

Pre-cast concrete panels bodies for constructions in building industry and a method of construction of structure using the pre-cast panel bodies is disclosed. The pre-cast concrete panels bodies includes pre-cast beams ( 3 ) at an upper edge and at least one bore ( 6 ) extending longitudinally from one end to the other. The bore is adapted to receive starter bars ( 16 ) reinforcement steel bars ( 19 ), wires, pipes or concrete. The upper edges of the panel bodies include cornices ( 4 ) casted simultaneously with the casting of the panel body. All the pre-cast concrete panels and pre-cast concrete slabs ( 26 ) are interlocked together by the introduction of steel bars ( 28 ) through links ( 8 ) extending from the pre-cast concrete panels, adding wires mesh ( 38 ) and top bars ( 40 ) on the pre-cast concrete slab and pouring concrete over the steel bars, wire mesh and top bars to provide a sturdy structure.
