Table 5.2 BUILDING Indology
Beam and Slab
ASSEMBLY
MATERIAL Form material: Beam: deodar wooden board. 10’-12’ length. Slab: ms plate Primary supports: 3”x5” wall plate, wooden section framing for beam form, angle section framing for slab form. Scaffolding: nilgiri wooden shores, working charpai with wooden shores
Indology
Overhang slab
Form material: Beam bottoms and side: deodar wooden boards Slab: ms plate Primary supports: 3”x5” wall plate, wooden section framing for beam form, angle section framing for slab form.
TECHNIQUE Wooden boards used for beams to get longer lengths. Boards joined with groove detail, to avoid leakage of slurry. Shuttering of beam is slightly tapered for easy removal. For slab, ms plate used in slabs, but they are plastered later. At junction of ms plate and wooden board, two different types of shuttering is either tied with each other or overlapped to avoid leakage
Beam bottom and side are wooden form. Slab bottom is ms plates. Near corner of overhang slab, for residue, pattern is created using steelwood farma as form panel, to maintain the texture.
Scaffolding: nilgiri wooden shores, working charpai with wooden shores

Beam and slab
Form material: Beam: Laminated plywood Slab: ms plate Primary supports: ms angle section framing to slab, wooden sections framing to beams Scaffolding: H-frames and ms shores, wooden shores
CEPT Library Slab
Form material: Laminated plywood sheet4’x8’
ms plates used for slab and plywood used for beams. Imprint of line at joining of two form panels continues from slab to beam. Both form panels are of same dimension. At junction inside, where two form materials meet; imprint of thickness of edge of either one is avoided. Casting is done in two parts, metal form overlaps plywood form. Pour joint of casting done in two parts can be seen outside, which is rendered later. Use of maximum size of panel to avoid wastage. Pattern of form sheet changes near cut outs in slab.
Primary supports: PERI girders
Scaffolding: Adjustable cup lock system
