As a revolutionary permanent formwork, the Austral Deck solution combines precast concrete panels with a cast in-situ topping to create a suspended concrete slab. Austral Deck is a exible solution designed to be installed with the entire range of Austral Precast Walling, Framework, Stairs and Balcony Solutions offering a complete precast
The first floor slab is a 5-inch-thick slab on ground. The perimeter walls are supported on continuous strip footings, and the interior foundations are spread footings on soft sandstone. The second-floor was an 8-inch-thick PT slab with a 2- to 3-inch-thick topping.
An ideal solution for remote private and public applications, the Tricon Plank-Deck Bridge System delivers safe, flexible and economical options for rapid bridge deployment. With minimal equipment and manpower required, this precast concrete bridge system can be erected and in use in one day.

Interface Horizontal Shear Strength in Composite Decks With Precast Concrete Panels monolithic roadway deck slabs. The use of precast concrete for new bridge construction and for the rehabilitation concrete topping that completes the bridge deck.
Whats Wrong with My Precast Concrete Parking Garage? 2 JOURNAL Glossary of Common Defects precast horizontal slabs, are typically reinforced with steel tendons that are prestressed. Embedded tendons are flanges create a large slab or deck that acts as the parking surface of the garage. Embedded steel plates in each
In this type of structural system, precast planks function as stay-in-place formwork and become a part of an overall composite slab once a field-cast topping is placed and the shoring is removed. Although this type of construction is common in bridge decks, it is more unusual in parking garages, except perhaps in the Delaware Valley and

INNOVATIVE PRECAST CONCRETE DECK SLABS Dr. S. Bala Balakrishnan, Ph.D., P.Eng. precast prestressed concrete deck slab panels for use in new as well as replacement bridge decks, is described. The precast portion of the deck is pre-tensioned and the cast-in-place topping is reinforced with one layer
Exeed Precast hollow core slabs are prestressed concrete elements that are cast with advanced extrusion technology to be used as floor and roof deck systems, partition walls as well as boundary wall panels. The addition of topping will produce fire ratings of up to four hours which will satisfy even the most stringent code requirements.
Precast Hollow Core Concrete Planks vs. Composite Slab 5.1 Problem Statement By using the composite slab, the precast concrete can be eliminated from the project. The Please see Appendix C for an image of the Deck/Slab Property Information window from RAM. The dead and live loads were also applied to the slab before the beams were designed.

Precast slabs are less thickness and thus reduced weight. Different composite slab thickness can be achieved, as required by structural considerations, by varying the topping thickness but keeping the precast thickness constant. The topping concrete and reinforcement provide a simple means of tying the floor and
Our building sturcture has some precast-prestressed hollowcore floor slabs. On top of the hollowcore slabs, a 2 in topping slab is placed to finish it off. The mix design of the topping is the same as the interior slabs on grade 3/4" aggregate w/ min. strenght of 3500psi, but 28-day breaks have been 4000 typically .
Flat slab bridges consist of prestressed, precast concrete deck panels that span from bent to bent. The panels act as permanent forms for a cast-in-place deck. The top surface of the flat slab is roughened to transfer horizontal shear. In some cases, transverse reinforcement is placed, to ensure horizontal shear transfer. A topping is then placed
