Formwork which is also popular as shuttering is the essential part of concrete that you use in construction. It is a temporary structure that holds fresh concrete and gives it a shape as per the required design. You have to remove formwork after the concrete gains minimum strength that it can take various loads on its own.
There are different types of formwork in which the concrete is hardened, matured, and attains its initial strength. For example, slab formwork, beam form-work, pier formwork, and wall formwork. Making formwork should take a lot of effort and time because the whole structure depends on it. You can use different types of materials for different formworks for example wood, steel, plywood, aluminum, etc.
Components of Formwork
Formwork is reusable and made of various components. Basic components of formwork are as below:
A form-work tie is a tensile unit. You can use it to connect opposite sides of the formwork to provide balance or you can say to resist the effective pressure that comes with the fresh concrete. Ties of formwork include an internal tensile member and an external supporting device. You must prefer steel for ties but in some cases, fiber-reinforced plastic ties also prove a good choice. There is a wide range of tie types. Some of them are reusable and some of them are disposable. For example, Coil and bolts ties are reusable and flat and ring ties are disposable ties.
Anchor is a device that you use to mend the form to the pre-placed concrete with satisfactory strength. It is generally rooted in the concrete during the placement process. Following are few factors as below that affects the bearing capacity of the anchor:
- The shape and material of the anchor
- Strength and type of the concrete implanted in the anchor
- The contacting area between the concrete and the anchor
- Embedded depth and position in the member
Hanger is the equipment that you can use for hanging formwork load. Hang formwork loads are the loads that come from structural steel, precast concrete, or other components.
Props are the vertical supports under the formwork. It takes care of the shuttering loads and other additional loads which include structure load, material load, workman crafts load, etc. You can generally use timber in the construction of props for traditional formwork systems. However for heavy constructions and structures, you must use either aluminum or steel props.
Spacer from Side
There must be the proper distance between the vertical shuttering and the steel bars for perfect construction. You can use the side spacer to maintain that distance.
There are different types of formwork based on different requirements in various sizes and shapes. Some of them are reusable and some of them are permanent. Hence for a successful and perfect construction, you should choose a formwork that perfectly fits the required job. But sometimes, the construction of formworks can be expensive; therefore, you should design economical formwork types and mechanize its construction.
