INSULATED PRECAST CONCRETE PANEL
INSULATED PRECAST CONCRETE PANEL: Insulated precast concrete panels consist of interior and exterior thickness of concrete with the rigid insulation inserted or ‘’sandwiched’’ between the two layers, thus their alternate name of insulated panel is “sandwich panels”. LAYERS IN INSULATED PRECAST CONCRETE PANEL: The two layers of concrete thickness, often referred to as concrete…

Load Bearing & Non-load bearing concepts in precast
What is load bearing (LB) precast element? Load bearing precast element is anything that receives load from a precast or structural members and transfers the load to another structural member or precast. These precast elements can also be used along as façade, boundary walls, or for architectural design purposes. What is non-load bearing(NLB) precast element?…

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…

BEAM Vs COLUMN
BEAM Vs COLUMN BEAM: A beam is a horizontal structural component that resists vertical loads. Its mode of deflection is primarily bending. It transfers loads imposed along its length to its endpoints to walls, column and foundations. The beam is structural element that stands against the bending. Mainly beam carries vertical gravitational forces, but also…

HOB AND ITS TYPES
HOB Hob is projection or recess on the top of slab, which is made up of concreate or sometimes precast. It will act as a base or foot for the precast panels and balustrade which are to be placed above the actual SSL (Structural surface level) and a locating guide sometimes with weather proof. HOB…
