All you need to know about Slab Formwork in Construction!!
There isn’t any doubt that formwork is one of the most essential components in any type of concrete construction. This particular term “formwork” refers to temporary or non-temporary molds into which the mix of concrete is filled up, which with time gets harden. It has been in the construction industry for more than tens of thousands of years, and for your better understanding, one of the earliest examples of formwork construction is the Pantheon in Rome, which was built around 120AD.
Without a doubt, when it is about construction, concrete is relatively stronger in resistance than any other material, but not to be forgotten, it has a very poor tensile strength, and because of this reason, most of the earliest concrete formwork consisted arched, vaults and domes. As concrete was available in limited amount and was complex to use, the earlier types of formwork were generally used in masonry.
Various types of Formwork
Depending upon the type of element of the structure to be build and the material of formwork, there are plenty of types of formworks that are accessible in the market. For your better understanding, Slap formwork in construction is utilized to build the concrete slab, whereas column formwork is used to make concrete columns and all this.
Slab Formwork in Construction is required, when suspended concrete slabs are constructed. But, it is important to know that they are not directly supported by the ground. This formwork in construction includes panels, stringers, shores, joists, etc. supporting materials that permit the concrete to be poured and set all above the ground. In slab formwork, ranges of materials are used, which includes plywood, timber, metal, aluminium, and sometimes even plastic components to give proper shape and size to the concrete to form the desired structure.
What exactly is Slab Formwork?
In building construction, slab formwork generally supports the weight of the concrete at the time of the curing process. However, bases are required to support the vertical stringer, which in results, supports horizontal joists. The whole-sole work of the horizontal joist is to make a flat surface where timber, plywood, steel sheets, aluminium, or fiberglass can be used as a base over which the concrete is filled.
In the maximum number of cases, the formwork can be re-utilized, and the method of removing formwork is known as stripping. Once the formwork is stripped, the surface must be cleaned to make sure that the faces of the panels remain straight, and there is no-development is concrete.
Depending on the project’s budget and specifications, it is important to choose the most durable and economical types of Slab Formworks are used. In case if you feel that you need more detailed information, please feel free to get in touch with us.
