What Is Jump Form In Construction?
Jump form or climbing formwork is a type of formwork used for constructing large vertical concrete structures like towers and skyscrapers. It is self-supporting, relying on the concrete already cast, and includes working platforms for fixing, cleaning and steel fixing.
Ideal for repetitive structures or those needing seamless walls, jump form systems are a practical solution for buildings where formwork and access from other parts of the building are not feasible.
Jumpform is ideal for building tall concrete structures like shear walls, core walls, lift shafts, stair shafts and bridge pylons. This system is designed to be fast, efficient and reduce labor and crane usage during construction.
The process is done in stages and the components are usually modular, allowing them to be joined together to fit the specific needs of a project. This makes Jumpform a highly productive solution for high-rise construction.
Benefits Of Jump Form
Jumpform construction method offers several advantages in building structures. Firstly, by careful planning, construction can be completed at a fast pace. The self-climbing formwork reduces the need for crane usage and this can lead to lower crane requirement on the construction site.
As the formwork is supported independently, the core and shear walls can be finished before the rest of the building structure. This results in high-quality surface finishes. Moreover, the formwork can be designed to withstand high winds, making it suitable for harsh weather conditions.
The highly engineered nature of jump form systems enables quick and precise adjustments in all planes and some formwork systems can even be used at an incline. The construction process requires a small but skilled workforce making it easier to plan construction activities due to the repetitive nature of the work.
Safety Of Jump Form
Jumpform Safety provides market-leading formwork systems that are built with safe working platforms, guard rails, and ladders. To enhance safety further, self-climbing formwork systems come with emergency braking devices.
This ensures the completed formwork assembly is robust and reliable. As a result, scaffolding and temporary work platform requirements will be at a minimum, which reduces congestion on site. Moreover, the rate of concrete used in areas that support the form must align with safety protocols to determine how quickly construction can progress safely.
Owing to its repetitive nature, workers become quickly versed with its associated health and safety standards.
Different Types Of Jump Form
Jump form is a formwork system used for the construction of multi-story buildings. There are four types of jump form: normal jump or the climbing form, guided climbing jump form, self-climbing jump form, and gliding form.
Normal jump uses a crane to lift units off one structure and relocate them to the next level; guided climbing requires an anchored structure as well as crane use; self-climbing uses hydraulic jacks that climb up rails without the need for a crane; and gliding involves continuous process using mounting mechanisms, creating seamless structures with an uninterrupted process.
