What Is Slab Formwork?

views

Slab formwork is used to construct a suspended concrete slab that is not directly supported by the ground. It acts as a mold in which fresh concrete can be poured in so that it can get a desired shape and size. When a slab is suspended, the formwork’s job is to support the concrete of the slab till it is perfectly cured. Therefore, you need a formwork to be strong enough to support the weight of the concrete while it sets.

Know the details

You can use different materials to create a formwork. The choice of material depends upon the size of the project. For example, you can use steel for larger projects while plywood or aluminum is suitable for smaller projects. You can also re-use many slab formworks. Hence, you must clean them after their use to ensure that the faces of the panels stay straight. There should be no concrete present on them. You can also prefer lamination for plywood forms so as to protect the wood from moisture damage. Also, plywood forms are very cheap.

Slab formwork includes formwork panels, joists, and stringers. To give the concrete its shape and strength, formwork also adds a variety of materials such as metal, plywood, and in some cases even plastic components. However, there is no wide usage of plastic components seen still now.

You can use wood or metals to build bases- also known as sills. The sill supports the vertical stringers that will in turn support horizontal joists. You can create a flat surface with the help of joists on which you can secure various pieces of plywood.

Types of modular slab formwork to consider

You can not only build horizontal surfaces by slab formwork but also you can set the formwork in a specified way to create a diagonal concrete structure or even an inclined one. Since slab formwork tends to be highly modular and customizable, therefore, we get endless shapes and designs.

Recoverable modular slab formwork

This slab formwork is light. You can recover it soon after the slab has set in. You can use various light elements to create this formwork. Hence, you can easily assemble and disassemble it.

Waffle formwork for grid slabs

This is flexible slab formwork and is optimal for lightweight slabs. The slab form is usually made of recoverable plastic molds. You can use it for different geometries as it is quite flexible.

Metal beam slab formwork

Though the formwork is made up of metal, you can easily customize it in the desired shape of the slab. Also, you can easily assemble and incorporate it anytime anyplace you want. It is most optimal for slab construction within walls
