Components of Mivan Formwork

The components of Mivan formwork are divided into 4 types based on the location of use –

1. Wall Components

A. Wall Panel

The basic and major component of Mivan formworks is the wall panels. It forms the face of the wall made out of an aluminum sheet properly cut to fit the exact size of the wall.

B. Rocker

Rocker is an L-shaped panel having allotment holes for stub pin to support the wall panels.

C. Kickers

It acts as a ledge to support the wall panels by forming a wall face at the top of the panel.

D. Stub Pin

It is the joining component of all other wall components.

2. Beam Components

A. Beam Side Panel

It is a rectangular structure cut into the required size of the beam which forms the sides of the beams.

 B. Prop Head and Panel for Soffit Beam

In the beams, where there is no support from the bottom, prop heads are used to support the beam. It has a V-shaped head for easy dislodging of the formwork.
A soffit beam panel is a rectangular aluminum structure placed in the prop head to support the soffit beams.

3. Deck Components

A. Deck Panels

A horizontal flat surface upon which the slab is cast.

B. Deck Prop and Prop Length

Deck prop is the same as that of the beam deck prop, here it is used to support the slab and bears the load coming on the deck panel.
Prop lengths are the vertical support to the deck prop which are adjustable as per the slab height.

C. Soffit Length

Soffit length provides support to the edge of the deck panels at their perimeter of the room.

Mivan Formwork Erection Process

1. Placement of Aluminum Formwork

  1. Mivan formwork is majorly used in the places where the whole structures made of concrete.
  2. All formwork is cleaned and coated with an approved realize agents.
  3. The wall reinforcing steel is placed with the floor slab.
  4. Along with the wall reinforcing steel, prefabricated room-sized walls panels and floor slabs panels are erected.
  5. Plumb, level, and dimensions are checked.
  6. The aluminum alloy slabs are accurately made as per the required sizes.
  7. Spaces for windows, ducts, doors and other features such as staircases, façade panels, and chajjas are also integrated into these structures.

Limitations of MIVAN Formwork

Even though there are so many advantages of MIVAN formwork the limitations cannot
be ignored. However, the limitations do not pose any serious problems. They are as
follows: –

1) Because of small sizes finishing lines are seen on the concrete surfaces.
2) Concealed services become difficult due to the small thickness of components.
3) It requires uniform planning as well as uniform elevations to be cost-effective.
4) Modifications are not possible as all members are caste in RCC.
5) Large volume of work is necessary to be cost-effective i.e. at least 200 repetitions
of the forms should be possible at work.
6) The formwork requires a number of spacers, wall ties, etc. which are placed @ 2 feet
c/c; these create problems such as seepage, leakages during monsoon.
7) Due to box-type construction shrinkage cracks are likely to appear.
8) Heat of Hydration is high due to shear walls.

Remedial Measures

In external walls, ties used in shutter connection create holes in the wall after deshuttering. These may become a source of leakage if care is not taken to grout the holes.

Due to box-type construction shrinkage cracks are likely to appear around door and window openings in the walls.

It is possible to minimize these cracks by providing control strips in the structure which could be concreted after a delay of about 3 to 7 days after major concreting. The problem of cracking can be avoided by minimizing the heat of hydration by using a flash.
