Precast Concrete Floor Detail

This section provides information and resources related to design of precast concrete systems as well as integration of precast with other systems.

Precast concrete floor detail.

Structural precast helps us build our foundations faster and better. When you specify an easi span building with a floor it is an all concrete solution. Precast concrete composite flooring is a high quality economical concrete floor construction where long spans and or high load bearing capacities are required. The material properties used are 6000 psi concrete in the precast element and either 250 ksi or 270 ksi prestressing strands.

Suspended concrete floors are constructed using prestressed planks supported by either masonry walls or a supporting steel frame structure. Foundational walls and the 1st floor can be completed in as little as 8 hours.

Easi span buildings can be specified with or without a floor. The floor panel is comprised of a topping or deck supported by a number of parallel longitudinal concrete stems that extend along the length of the panel. However for the spancrete hollowcore plank the fire endurance provided will have an effect on load capacity. We carry a permanent stock of over 25 000m of 155mm concrete floor beams in varying lengths to suit any order.

The precast concrete floor unit is used to span between supporting steel beams as an alternative to in situ concrete and metal decking. We completed excavation to backfill in only five days.

The joints between the units are grouted with in situ concrete and a concrete structural topping is provided for some applications. Connection details adobe pdf file joint details. Precast components can be delivered as needed to fit tight construction schedules with minimal site traffic and neighborhood disturbance. Milbank precast beam and block concrete floor beams are expertly manufactured by our experienced operations team at our facilities in essex uk and are cast to a high quality with excellent durability longevity.

The concrete stems extending between the end blocks are spaced 2 ft on center. Precast concrete shear wall panels provide a lateral load resisting system when combined with the diaphragm action of the floor construction. For the beams and double tees the capacities are somewhat independent of the available fire rating. The easi span floor system is a floating foundation that is post tensioned for added strength and durability.
