Steel formwork is a steel formwork used for concrete pouring. In addition to steel formwork, there are wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects due to its multiple use and beautiful appearance of concrete pouring. According to the purpose of steel formwork, it can be divided into: civil construction (house construction) steel formwork. There is also a combined steel formwork divided into: large formwork, small formwork, medium formwork, internal corner, external corner, etc.
Forms are molds to receive concrete in its’ plastic form.• Formwork is temporary structure, as such, it is notnormally shown on the drawings.Formwork for Beams and Slabs
Steel Formwork Definition
Its is an artificial support provided below and around theprecast or cast in situ concrete work.• Formwork is commonly made of• Steel• wood• Formwork construction & casting is of prime importancein concrete industry. It share a significant amount ofconcrete cost.
Qualities of Steel Formwork
It should be water tight• It should be strong• It can be reusable• Its contact surface should be uniform• It should be according to the size of member.
Types of formwork
Formwork are mainly of two types• Steel formwork• Wooden formwork• Steel formwork is made of• Steel sheets• Angle Iron• Tee Iron• Wooden formwork consists of• Props• Planks battens• Ledgers• sheeting
Temporary Structure- Temporary structure required to safely support concreteuntil it reaches adequate strength.• Permanent Structure-Permanent formwork remains in situ for the life of thebuilding
This consist of panels fabricated out of thin steel platesstiffened along the edges by small steel angles.• The panel units can be held together through the use of suitableclamps or bolts and nuts.• The panels can be fabricated in large number in any desiredmodular shape or size.• Steel forms are largely used in large projects or in situationwhere large number reuses of the shuttering is possible.• This type of shuttering is considered most suitable for circularor curved structures.
For heavy concrete work
With reasonable care will last indefinitely• High initial cost and high handling cost
The first floor circular columns were constructed using steelcolumn forms. The steel column form should be oiled beforeconcreting.
After concreting to the first floor columns, the steel column formswere dismantled easily.
Compared with timberformwork• Steel forms are stronger, durable and have longer life thantimber formwork and their reuses are more in number.• Steel forms can be installed and dismantled with greaterease and speed.• The quality of exposed concrete surface by using steelforms is good and such surfaces need no furthertreatment.• Steel formwork does not absorb moisture from concrete.• Steel formwork does not shrink or warp.
STEEL FORMWORK ANDACCESSORIES
Steel formwork systems for every size and shape ofground plan, in practical dimension & equipped withdifferent features to make shuttering more efficient.
