Horizontal System in Tower Based Formwork

Light Modular Formwork

The horizontal system is made of secondary and primary beams (in construction jargon: “ligers” and “unterligers”, respectively).

The horizontal system comes in contact with the cast concrete element and transfers the load to the shoring towers. 

The secondary and primary beams that exist in the market are made of wood, steel and aluminum. 

The coating is, often, made of plywood or wooden boards. Yet, it can also be made of steel. 

When economically assessing an overall system, the horizontal system functions as a significant factor, since it determines the distance between the shoring towers. 

The more strength the secondary beams and joists hold (for bending, cutting and sinking), the better and more efficient it will become when using the towers.

It is crucial that the components of the horizontal system will have a low weight, so their assembly will be carried out without any devices for lifting, and that the workers’ manual assembly will require a low work inputs.

A horizontal system made of aluminum and wood is considered as light, especially in comparison to the one made of steel, and can be assembled without any auxiliary devices for lifting.
