TEMPORARY CONNECTION WITH DETAILS
Precast erection procedure having the set of sequences. When the panel is installed on the slab, props are fixed to stable the panel, then panel was unhooked from crane then the temporary stich plate or stich angles are connected to the next panel through cast in ferrule, which is casted on the precast panel. The…

CAST-IN PLATE WITH DETAILS
A steel plate which is casted in to concrete for connection purpose is named cast-in-plate. Connections may be required to carry shear and axial force between the precast elements for applied load conditions. Cast-in plates are used to tie/ fix, Concrete or precast panels to each other. Precast to insitu slab. Steel beams to the…

TABLE PRECAST FINISHES
Table precast finishes is the replication process. The surface of the manufacturing table affecting the precast surface. Sometimes the table is covered by form liners, bricks, signage letters & pattern to make the finishes. a) Normal table finish: Non-exposed surface of the precast is made by this type of table. Same table is used for…

DEMOULDING SLOPE
Demoulding of precast member without damage to either the components like lifter or mould is critical to successful replication process for the particular complicated design. During mould design, the designers concentrate to make minimum draft (nearly 10 ) on mould to wherever the possible to minimize demoulding force and resultant stress on lifters and prevent…
