the hollow core slab has a variety of uses, including floors and roofs for buildings and parking garages, decks for piers, and lagging for retaining walls. cast-in-place, composite concrete topping is highly recommended to provide a smooth, level floor surface that serves as a horizontal diaphragm when properly reinforced.
the floor slab may be in the form of a precast concrete slab or a composite slab with metal decking either shallow or deep decking may be used . an added benefit is that some forms of shallow floor construction inherently achieve composite interaction between the beams and slab, thereby enhancing structural efficiency.
precast beams and columns provide the ability to prestress the beams and columns as production occurs off-site. the product thickness is designed as 75, 95, or 115 mm prestressed slabs and used on site with a 50 mm reinforced topping screed in an unpropped construction.
learn how to model a hollow core type family. known issues for hollow core families . strands only have one diameter. free form rebar will pass through inner openings. voids do not update when the width of the hollow core slab is modified. to update this geometry, re-split the floor. strand diameters should be more than 5 mm.
maximize space in any house plan with hollowcore roof and floor systems. create extra living and storage space by using a home's entire footprint, even neglected space available under a garage, porch or stoop. as more residential covenants dictate restrictions, hollowcore helps home owners gain more usable space. second garage; indoor sport court

we can also form holes for services and soil pipes during manufacture at no extra cost. hollowcore planks also offer increased fire protection as the increased mass acts dramatically to slow the spread of fire. made to measure concrete slabs.
note: each producer of hollow-core slabs uses a trademarked process that creates different shapes to form the voids within the pieces. information on the key types of hollow-core and the signature shapes produced by each process can be found in the pci design handbook 7th edition. load tables and span charts can be found under design resources.
precast concrete hollow core floor slabs.. hollow core slabs are precast, prestressed concrete elements that are generally used for flooring. the concrete hollow core slabs have between four and six longitudinal cores running through them, the primary purpose of the cores being to decrease the weight, and material within the floor, yet maintain maximal strength.

my litedeck rep came back with $3.25sqft for the floor forms. it would probably be cheaper to form it with plywood, however this space could be used as a heated shop, so an insulated floor may not be a bad idea. still, the litedeck, poured, is pushing half the price of a hollow plank.
as a result, hollowcore plank offers a higher span-to-depth ratio. the underside of hollowcore plank is steel form smooth, and can be either left as is or painted with a textured paint. in many floor applications, hollowcore plank may be used without concrete topping.
