hollowcore flooring units 04

Prestressed hollowcore units are the ideal solution for all suspended floor applications – especially where a clear spanning durable deck is required.

• Clear unpropped spans up to 14.0 metres • Can be used on masonry, steel or concrete structures • Fast to erect and structure provides an immediate working platform • Service holes and notches can be preformed • Excellent sound and fire resistance properties The structural properties of the hollowcore units rely on the prestressing strands cast into the lower half of the units. The number of strands and the degree of the prestress determines the ultimate load/span capacity of the units. Hanson can provide software to assist the designer to design the floor units for a particular application. All units are machine produced ensuring consistently high quality and the steel beds produce a smooth, regular soffit When grouted together hollowcore units can provide diaphragm action without structural topping. Enhanced structural performance can be achieved by using a composite topping.

transfloor A direct equivalent of an insitu slab, Transfloor provides the facility to combine precast and insitu concrete and offers major benefits to specifiers, engineers and builders.

• Fast to erect, acts as fully participating permanent formwork, saving time and money • Exceptional flexibility where each panel can be designed to suit a specific location and load • Irregular shaped buildings easily accommodated • Service holes etc formed and positioned during manufacture • Smooth level soffit suitable for direct decoration The use of site placed concrete effectively ties all the Transfloor panels together providing safety, rigidity and structural redundancy. The lattice girder truss ensures a practical bond between the precast and insitu concrete. All Transfloor panels incorporate triangular lattice girder trusses. Each truss is cut to size and attached to the layer of reinforcement. Concrete is then poured to create the Transfloor panel. The trusses cast into each panel provides the strength and stiffness for handling and transport, allows the panels to support construction loads with a minimum of temporary propping and contributes to the bottom steel. The length, width, thickness, plan shape and reinforcement steel of a Transfloor panel can easily be varied to suit design requirements.

beamshells 06

Beamshells are composite precast elements that usually contain all the positive main beam reinforcement and stirrups in an efficient use of concrete for economy and ease of handling. Beamshells are most economical when part of a system comprising

• insitu concrete columns • standard beamshells • hollowcore floor planks • insitu structural topping

benefits of beamshells • precast in a factory, away from your building site • minimum trades required on site • simple column connections • fast construction times • multiple work faces Hanson can also offer precast beams for suspended floors. Precast beams are not a stock item, but are manufactured to suit each particular situation, hence there are no preset restrictions. There are a number of profiles that can be used from inverted tee beams to solid rectangular beams. Reinforcing can be prestressed or conventionally reinforced

manufacturing facilities and services Hanson supplies precast products from three modern factories located in the Sydney metropolitan area. Hanson can offer a precast concrete solution for most building applications. Architectural precast, hollowcore walling and flooring, structural grey panels, beams and columns are all part of the extensive range of products that Hanson offers.
