A ribbed rubber mat is an effective concrete flooring solution.
Ribbed floor shell concrete.
Ribbed waffle slab system.
Loadbearing capacity and fire protection restored.
Depending on the loads ribbed floors can be realized with prestressed free spans of up to 7 000 mm in length.
Ribbed slab is a type of reinforced concrete slabs in which some of the volume of concrete in the tension zone is removed and replaced with hollow blocks or left as voids.
This system is an economical alternative to timber floors while achieving good sound transmission and fire ratings.
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.
The repair of the ribbed floor slabs was undertaken by the company betos gmbh gelnhausen germany with.
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.
Ribbed slabs are made up of wide band beams running between columns with narrow ribs spanning the orthogonal direction.
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.
Often the thinnest floor is not the most economical.
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.
Ribbed and waffle slabs they provide a very good form of construction where slab vibration is an issue such as laboratories and hospitals.
Project specific slab designs are created using an optimised combination of pre stressed slab beams in conjunction with our infill options.
This form of construction is not very common because of the formwork costs and the low fire rating.
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.
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.
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 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.
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.
