Ribbed floor shell concrete.

These are designed for flooring a height of 350 mm regardless of the insulation value and are suitable for use as a self supporting suspended floor in the home or commercial buildings.

Ribbed waffle slab system. This is a strong and resilient material in fact it is the most widely used man made building material in the world.

Our aim is to enable all those involved in the design use and performance of concrete and masonry to realise the potential of these materials. This form of construction is not very common because of the formwork costs and the low fire rating. Ribbed slabs are made up of wide band beams running between columns with narrow ribs spanning the orthogonal direction. The thicker floor may require less prestress and shear reinforcing which can go some way towards offsetting the cost of the extra concrete in the precast unit.

A ribbed rubber mat is an effective concrete flooring solution. Stahlton s rib and in fill flooring system incorporates pre stressed concrete ribs permanent formwork and an in situ concrete topping to give an extremely lightweight and versatile suspended floor.

Depending on the loads ribbed floors can be realized with prestressed free spans of up to 7 000 mm in length. The repair of the ribbed floor slabs was undertaken by the company betos gmbh gelnhausen germany with.

This reduction in the volume of concrete in the tension zone below the neutral axis is based on the assumption that the tensile strength of concrete is zero hence all the. Ribbed and waffle slabs they provide a very good form of construction where slab vibration is an issue such as laboratories and hospitals.
