  4. 4. Chapter – 1 Introduction to Formwork 4
  5. 5. 1. Introduction: 1.1 Definition of Formwork: When concrete is placed, it is in plastic state. It requires to be supported by temporary supports and castings of desired shape till it becomes sufficiently strong to support its own weight. This temporary casing is known as the formwork or forms or shuttering. 1.2 General Introduction: • Formwork plays a key role in concrete construction. • Forms are the moulds & dies of concrete construction. • They mould the concrete to the desired size & shape & control its alignment & position. • Formwork also carries the weight of freshly placed concrete and itself besides live load due to materials, equipment and workmen 5
  6. 6. 1.3 Importance of Formwork: •In the Construction of any building concreting and reinforcement binding is the main activity after that to hold them in their position Formwork is most important • Formwork constitutes 20% of the standard cost and 60% of the time in concrete construction. • Thus a good formwork system helps in achieving speed, quality, economy and safety in reinforced concrete construction 6
  7. 7. 1.4 Requirement of Formwork: • To obtain the required shape, size, finish, position and alignment of concrete members. • To have enough load carrying, or transferring capacity to take pressure or weight of fresh concrete and any other loads, without distortion, deflection, leakage, failure or danger to workmen. • To have design for quick erection and removal. • To handle easily using available equipment or manpower. • Joints between formwork must be tight enough to prevent leakage of grout.
  8. 8. 1.5 Based on material Various Types of Formwork are :  Plywood (Fig-1.1)  Bamboo (Fig-1.2)  Steel (Fig-1.3)  Aluminium (Fig-1.4)  Plastic (Fig-1.5) 8

  14. 14. Chapter – 2 Mivan Formwork System 14
  15. 15. 15
  16. 16. The technology has been used extensively in other countries such as Europe, Gulf Countries, Asia and all other parts of the world. MIVAN technology is suitable for constructing large number of houses within short time using room size forms to construct walls and slabs in one continuous pour on concrete. Early removal of forms can be achieved by hot air curing / curing compounds. This facilitates fast construction, say two flats per day. All the activities are planned in assembly line manner and hence result into more accurate, well – controlled and high quality production at optimum cost and in shortest possible time. 16
  17. 17. Fig-2.1 Wall Assembly Details 2.3 Mivan Formwork Assembly: MIVAN aims in using modern construction techniques and equipment in all its projects. On leaving the MIVAN factory all panels are clearly labeled to ensure that they are easily identifiable on site and can be smoothly fitted together using the formwork modulation drawings. All formwork begins at a corner and proceeds from there. 17
  18. 18. Chapter - 3 Procedure For Using Mivan Formwork 18
  19. 19. 3.0 Procedure For Using Mivan Formwork: 3.1 PRE – CONCRETE ACTIVITIES: a) Receipt of Equipment on Site – The equipments is received in the site as ordered. b) Level Surveys – Level checking are made to maintain horizontal level check. c) Setting Out – The setting out of the formwork is done. d) Control / Correction of Deviation – Deviation or any correction are carried out. e) Erect Formwork – The formwork is erected on site. f) Erect Deck Formwork – Deck is erected for labours to work. g) Setting Kickers – kickers are provided over the beam. 19
  20. 20. i. Dislodging of pins/wedges due to vibration. ii. Beam/deck props adjacent to drop areas slipping due to vibration. iii. Ensure all bracing at special areas slipping due to vibration. iv. Overspill of concrete at window opening etc. 3.2 ON CONCRETE ACTIVITIES: 20
  21. 21. A) CLEANING: • All components should be cleaned with scrapers and wire brushes as soon as they are struck. Wire brush is to be used on side rails only. B) TRANSPORTING: • The heaviest and the longest, which is a full height of wall panel, can be carried up the nearest stairway. Passes through void areas. C) STRIKING: • Once cleaned and transported to the next point of erection, panels should be stacked at right place and in right order. •D. Erecting of Formwork: • After that formwork is erect again on the next floor. 3.3 POST – CONCRETE ACTIVITIES: 21
  22. 22. 3.4 Sequence For Striking And Erecting The Wall Mounted On Working Platform is as follows: Fig-3.4.1 Erection of Platform On 2nd Floor 22
