T-beams and hollow blocks are an important part of combination -or composite floors and they are referred to like this because they are composed out of several elements, of which T-beams and hollow blocks (also known as filling elements) are part of.
To be more precise, this kind of floor is being made by first laying out pre-stressed concrete reinforced beams. By pouring concrete on the compounded floor is becomes one uninterrupted unit. The concrete forms a wedge between the beam and the filling element, while at the same time acting as a pressure layer. While constructing such a composite floor struts are often being placed, but by using a combination of lattice beams and pre-stressed reinforcements it is possible to go without them.
A big advantage of a combined floor system is that it can be placed manually, without the need for a crane, just as it can be applied to all floors and on all types of buildings, both for new construction as with renovation of old and/ or monumental buildings.
Concerning T-beams, these are being made by pouring the molten metal in T shaped molds, at the factory. This gives them an exceptional amount of dimensional stability. After that the reinforcement is being pre-stressed, giving the beams proper performance. The small measurements of these T-beams ensure the optimal use of the primal construction materials. In practice this is being done be placing these construction elements parallel, usually with a regular interval of 60 cm (h.o.h) and sometimes two by two.

Hollow blocks, also known as “filling elements” are in fact the formwork of the T-beams and the stuffing of the floor. As the name implies, hollow blocks are being used to fill up the area of the floor between the several T-beams. Hollow blocks are also being used in the construction of spans. Regarding the construction of a composite floor, these elements are being placed between the T-beams, after which a layer of concrete is being poured over this combination of hollow blocks and T-beams, acting as a compressive layer.
The hollow blocks can measure a height of 12 to 16 cm, making it possible to achieve the ideal size in regards to the bearable load, span and other possible demands like fire resistance. Both the hollow blocks as the T-beams are always in stock.
