High labour costs on construction sites increasingly require easier and faster formwork systems. Without exception, the number of components to be moved determines the shuttering times and ultimately the cost of construction.
Thus a versatile formwork system creates a minimum of different components which meets and exceeds the demands of the modern-day job site in a simple way. Fewer individual components for faster forming.
The standard 'jump' height is the typical floor height approx. 4.2 metres. The shutter height can be extended up to approximately 4.5 metres to suit non- standard floor heights; for extensions beyond that, it is typical to construct the lift in 2 pours.
In order to enable the construction team to work safely and efficiently, there are two working platforms, one at the top (upper) and the other at the bottom (main platform) of the shutter. After concrete has been poured and the concrete has achieved its 'initial set and strength', typically after 12 - 16 hours, the shutters are withdrawn from the walls using the rack system (no cranage required), and cleaned/prepared for the next lift.
In addition to the upper and main working platforms there are 'hanging or trailing platforms, as many as three in some cases, to give safe access for follow-up work such as recovery of the 'shoes' fixing of brackets for supporting internal slabs, welding of 'fin-plates' in preparation for erection of structural steelwork or preparatory work by other trade contractors.
Advantages
- The external structural frame is constructed normally within 6 floors of the core, therefore the core there is generally no requirement to alter the structural design.
- Internal slabs and stairs can be constructed with the core walls.
