The Composite Slab
Description of the Composite Slab Solution
This is a unidirectional composite slab in which concrete is poured onto a corrugated sheet profile that serves both as formwork and as positive framework. Once the concrete sets, this profile collaborates absorbing the tensile stresses.
This type of slab was first used in the U.S. in the 50's for the construction of skyscrapers as it can be constructed without the use of props. Since then, its use has extended throughout Europe (late sixties) until the present day.
Composite sheet slabs support both repetitive and abrupt static and mobile loads that do not exceed the limits indicated in the current building regulations.
Although they are specially designed for installation on metallic structures, they may also be used on concrete, wood or masonry structures.
Advantages of the composite slab
The main advantages of the collaborative slabs are the following:
- Versatibility; It accommodates many practical cases and a multitude of solutions in plant.
- Resistance / Weight ratio; It achieves greater resistances with a lower own weight, which allows to reduce the overall weight of the structure. It starts from slabs of only 12 cm.
- Quick installation; the possibility of avoiding shoring allows the concreting of more than one plant at the same time reducing the construction time per plant.
- Cost reduction; both labor, since shoring is avoided, as materials, because it uses less volume of concrete with the consequent decrease in the weight of the structure and waste.
In addition to these advantages we obtain other additional no less important ones like the constructive facility, the non-contamination of other materials, the ease of collection and cleaning, its function of formwork and secure platform on which to work, the bracing of the structure and the ease of installation of the facilities, among others.
Applications
This type of slab is suitable for a wide range of applications:
- Housing
- Industrial buildings
- Car parks
- Offices
- Public buildings
- Shopping and leisure centres
- Warehouses
