T-beams and hollow blocks
T-beams and hollow blocks are important components in combination or composite floors. As their name suggests, such floors are made of a number of different elements, including T-beams and hollow blocks (also known as filling elements).
Combination or composite floors are made by:
- Laying out concrete beams with filling elements, with additional reinforcement.
- Pouring a layer of concrete on the compounded floor to create a single unit. In doing so, the concrete forms a wedge between the beam and the filling element whilst also acting as a pressure layer.
- Floor struts are placed when assembling a combination or composite floor. Working without the floor struts? Then a combination of pre-stressed reinforcements and lattice beams are used.

A combination floor system can be laid manually and without a crane. It can be used in all types of building, including new buildings and in the renovation of old and/or monumental buildings and at all levels.
T-beams are made by pouring molten metal into T-shaped moulds. This gives them an exceptional amount of dimensional stability. The reinforcement is then pre-stressed, which makes the beams highly effective. The small size of these T-beams means that optimal use is made of the primary resources. In practice, construction elements are placed in parallel, usually with an average interval of 60 cm and in some cases two by two.

Hollow blocks, also known as “filling elements”, create the formwork of the T-beams and filling for the floor stuffing. As their name suggests, hollow blocks are used to fill the parts of the floor between the different T-beams. Hollow blocks are also often used in the construction of spans.
When laying a composition floor, hollow blocks are placed between the T-beams. A layer of concrete is then poured over, creating a pressure layer.
The hollow blocks can be between 12 and 16 cm high. This size is ideal in allowing them to support the load and span whilst also being fire resistant. Both hollow blocks and T-beams are always in stock.
