Mivan shuttering

Recent Technology in Construction

1. MIVAN SHUTTERING

2. INTRODUCTION Mivan shuttering is a fast-paced construction technique which offers strength and durability to a building by use of aluminium formworks.

3. Methodology The basic element of these structures is panel. It is made up of aluminium which is of light weight It yields minimum deflection under loading These are manufactured in different sizes as requirement of the project The panels are made thick from high strength aluminium alloy with a 4mm thick plate and 6mm ribbing behind to stiffen the the panels

4. Construction Technique 1.Setting up the Reinforcement – The wall reinforcing steel is given from the footing to the bottom level of slab as given in the design . It is used to give a structure to the building and support the building.

5. 2.Placement of Aluminium formwork – Along the wall reinforcing steel , prefabricated room sized walls and floor slabs are erected. The aluminium alloy slabs are accurately made and are easy to handle. Spaces for Windows ,ducts ,doors , and other features such as staircases , faced panels and chajjas are also integrated in these structures . The forms are joint together using the pin wedge system , which can be dismantled quickly after the concrete structure is made .

6. Components of Mivan Frames

7. Wall Components

8. Grippers These are used to hold the panels of the walls and prevent them from displacement. These are made up of aluminium of thickness 3mm.

9. FOR STAIR CASES Stair cases are also built by placing the Mivan Shutterings in the required shape as size

10. 3.Pouring of Concrete – After the casing of walls and slab is done , high quality self compacting concrete is poured , which takes forms and shapes of the frame used, which is later removed and gives monolithic structure.

11. After the removal of the shuttering plain and smooth walls are obtained which requires no plastering

12. ADVNTAGES OF MIVAN STRUCTURES Increased Durability – The durability of the completed structure is more than general brick masonry walls. Lesser no of joints – thereby reducing the leakages and enhancing the durability. Integral and Smooth finishing of wall and slab – Smooth finish of aluminium can be seen vividly on walls. More seismic resistance – The box type construction provides more seismic resistance of the structure. Negligible maintenance – Strong built up of concrete needs no maintenance.

13. Faster completion – Unsurpassed construction speed can be achieved due to light weight of forms. Lesser manual labour – Lesser labour is required for carrying formworks. Simplified foundation design due to consistent load distribution The natural density of concrete wall result in better sound transmission coefficient.

14. LIMITATIONS OF MIVAN Concealed services become difficult due to small thickness of components. It requires uniform planning as well as uniform elevations to be cost effective. Modifications are not possible in this type of structures as the members are cast in RCC . The formwork requires number of spacer, wall ties etc. which problems of seepage during rainy seasons. Heat of Hydration is high due to shear walls. Due to box-type construction shrinkage cracks are likely to appear

15. S.No Characteristics Mivan formwork Conventional 1 Speed of construction Four days cycle per floor Ten days cycle per floor 2 Quality of surface finish Excellent, plastering is not required Bad 3 Pre-planning of form work system Required Not Required 4 Type of construction Cast in situ cellular construction Simple RCC framed construction 5 Wastage of form work material Very less In great amount 6 Accuracy in construction Accurate construction Less than Aluform 7 Coordination between different agencies Essential Not necessarily required 8 Resistance to earthquake Good resistance Less than Aluform 9 Reusage value 250-300 50 Comparison between Mivan formwork and conventional formwork

16. CONCLUSION It is a good advancement in construction field which is very useful for mass housing with little disadvantages.
