CLAIMS:

I claim:

1. A modular slab formwork with easy shuttering and de- shuttering assembly comprising:

a formwork panel, wherein the formwork panel comprises a plurality of side connectors, a base frame, and a form-lining, wherein the base frame comprises a corner element on each corner;

a drophead, wherein the drophead is connected to each comer of the formwork panel through the comer element; and

a prop, wherein the prop creates a vertical support to the formwork panel through the drophead over a ground surface;

wherein, the drophead is hooked to a slotted window of each corner element, wherein the corner element facilitates locking of at least two formwork panel with each other as well as with the drophead through the slotted window.

2. The slab formwork as claimed in claim 1, wherein the base frame has a chamfered corner element with a slotted window and a bottom rim.

3. The slab formwork as claimed in claim 1, wherein, the drophead comprises a top plate, a fly plate, a wedge, a stem, a bottom plate and a locking bolt.

4. The slab formwork as claimed in claim 3, wherein a base plate of the prop is connected to the bottom plate through the locking bolt, wherein the stem is fixed at a central axis of the bottom plate and further connected vertically to the wedge and the top plate respectively.

5. The slab formwork as claimed in claim 1, wherein a comer of the base frame is chamfered at an angle range 40°-50° leading to a connection with a top plate of the drophead.

6. The slab formwork as claimed in claim 1, wherein a comer of the base frame is chamfered at a preferable angle range 45°.

7. The slab formwork as claimed in claim 5, wherein the wedge has dual action of successive detachment of a corner element formwork panel by releasing the locking followed by gravity-based dropping of fly plate.

8. The slab formwork as claimed in claim 3, wherein the wedge comprises a side guiding and an inner slopping level, wherein the fly plate is interlocked with the wedge through the side guiding.

9. The slab formwork as claimed in claim 8, wherein the fly pate comprises a fly plate pin hinged to the comer element, wherein the fly plate pin is unhinged by applying a lateral force on the wedge leading to an angular movement of the fly plate through the inner slopping level.
