Ribbed Floor Shell Concrete

Depending on the loads ribbed floors can be realized with prestressed free spans of up to 7 000 mm in length.

Ribbed floor shell concrete.

This form of construction is not very common because of the formwork costs and the low fire rating. The concrete centre part of the mpa mineral products association mpa is the trade association for aggregates asphalt cement concrete dimension stone lime mortar and silica sand industries. Loadbearing capacity and fire protection restored. Ribbed slabs are made up of wide band beams running between columns with narrow ribs spanning the orthogonal direction.

Ribbed and waffle slabs they provide a very good form of construction where slab vibration is an issue such as laboratories and hospitals. Ribbed floors consisting of equally spaced ribs are usually supported directly by columns they are either one way spanning systems known as ribbed slab or a two way ribbed system known as a waffle slab. Often the thinnest floor is not the most economical. This system is an economical alternative to timber floors while achieving good sound transmission and fire ratings.

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. Increasing the floor thickness may only require a small amount of additional concrete to form a deeper rib or web. The ribbed concrete floor slabs underneath showed serious damage extending to partly exposed reinforcement so that the loadbearing capacity of the floor was no longer ensured.

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. Ribbed slab systems we have an extensive range of precast pre stressed slab systems which provide a fast cost effective and simple solution for any suspended slab requirement. When it comes to industrial flooring options there s little question as to why concrete is the preferred choice. A ribbed rubber mat is an effective concrete flooring solution.

Ribbed waffle slab system. 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. Project specific slab designs are created using an optimised combination of pre stressed slab beams in conjunction with our infill options. This is a strong and resilient material in fact it is the most widely used man made building material in the world.
