Brick suspended ceiling with concrete

Ceiling type in which ceiling tiles are hung on site between prefabricated reinforced concrete beams with brick shells underneath. In addition, the slab is given a layer of in-situ concrete which, depending on its thickness and the slab statics, may require its own reinforcement. Depending on the thickness of the concrete layer, brick suspended slabs with concrete are

    referred to
  • as beam slabs with a thickness of the concrete layer of up to 3 cm,
  • as ribbed slabs with a thickness of the concrete layer of at least 5 cm and
  • as slab beam slabs with a thickness of the concrete layer of at least 7 cm.

 

The beams are usually laid in a grid of 62.5 cm and are considered to be uniaxially tensioned systems. The ceiling tiles are hung by hand between the aligned beams. The concrete layer is then concreted, whereby the bricks and beams are also poured together in the same step. The bond is achieved via the reinforcement protruding from the precast girder. If necessary, the slab is also poured in the same operation with circumferential ring anchors and beams. Assembly support is always required.

 

This type of ceiling is used, among other things, in the renovation of old buildings and in confined spaces. Its individual parts are lightweight and can be transported and used without heavy equipment, lifting equipment is not mandatory. Since the concrete layer can have a strong influence on the statics of the brick slab, the variant of the brick suspended slab with a reinforced concrete layer is used, especially in the case of large loads. The reinforced concrete beams must be approved by the building authorities.
