Description of elements

Ribbed floor shuttering or TT slabs are made fromprestressed concrete. They are used for the construction of flat or oblique roof and also as plate floor. For standard modules, width of 250cm, there are four heights of elements: H=30cm, H=40cm, H=50cm i H=60cm. Fire resistance to R60’.


In using of TT slabs as roof covering, monolythisation is optional. Thermal insulation is laid over it, and than waterproofing, consecutively. During construction of plate floor, it’s planned to put a stabilizing bed of concrete (minimum thickness of 5 cm) over TT slabs, reinforced with wire mesh. In execution of a stabilizing plate, the upper surface are grouted with concrete class not less than 30N/mm2 , granulometric composition of 0-12.
