What is construction formwork?
Construction formwork is a concrete mold in many professional documents, it is often called a formwork system. Formwork is also known by Vietnamese as Coffrage, because it comes from French, Coffrage, and in English, Form-work. Construction formwork is construction equipment, used to fabricate structures of concrete and reinforced concrete.
Some notes when designing formwork in construction works
Construction formwork
– The cost ratio for formwork is usually quite high, so it is necessary to spend time researching formwork structure types and formwork technology to suit the project.
– The labor and material costs of formwork are quite different; So when researching formwork should not only consider material factors, but should pay attention to labor factors (processing, installation and dismantling).
– Choose formwork materials to suit large or small workloads, short or long construction time.
– When designing formwork, attention should be paid to standardizing formwork parts so that they can be used many times, in many places. It is recommended to set up standard formwork with many size modules, many bearing strength modules, applicable to many different types of structures. For example, the support bar underneath the bottom formwork can be made of a variety of materials (wood, shaped steel, steel pipe), many different sizes and many different bearing capacity.
– It is necessary to tabulate the allowable loads for each formwork part in all usage conditions. Unified how to determine construction loads, determine concrete lake pressure on all forms of formwork; US documents say that the concrete pressure in the column formwork is greater than the concrete pressure in the wall formwork. Horizontal pressure of the concrete tank how to pour concrete and the capacity of the reservoir tank.
Vietnam Construction Board Company has always released generations of construction formwork such as plastic formwork, iron formwork, especially high-grade film-coated boards are used in projects that require high quality such as hotels, Traffic underground tunnels, high-rise apartment buildings, luxury villas.
