7 shows a system in which a raised floor (41) is supported by supports (42) above a pre-cast concrete unit (39) having a structural topping (40), which in turn is supported by a cellular beam (37) having openings (38). The pre-cast concrete units (39) are tied together by reinforcement rods (43) or other
Range pre cast systems hollow core, pre cast beams with timber infill, flat slab, beam and slab;. permanent formwork. Performance criteria. 1.1 Proprietary suspended concrete floor systems are identified and described in terms of purpose, components and differences between types. 1.2 Proprietary suspended concrete
commercial projects, schools, clinics and suspended ground floors in areas of clay heave and shrinkage. These slabs are traditionally used as suspended floors for buildings up to 4 floors. 2 DESIGN OVERVIEW. 2.1 Hollow-Core Used As Flooring. Hollow-core concrete slabs offer several advantages over insitu floor casting
When building with precast concrete products, a significant advantage is that all components are cast off-site and can be assembled quickly, saving time To see an example of how our Hollowcore Flooring and Precast Stairs and Landing can be used, have a look at this Case Study of a recent project.
Lifting inserts are cast into the units during production, these lifting points are then used to handle the planks within the factory and once again on site. The wideslab floor lifting system also eliminates the need to “bar” individual floor beams into final position as is typical of hollowcore flooring lifted with chains or beam
Prestressed Concrete Floors. This type of slab is a slipformed casting process on continuous steel beds 130m long. Core formers are part of the casting machine and forms the hollows during the casting process. Find out more. Prestressed-hollow-core-security-walls
ing suspended slabs in buildings tend to impact significantly on the delivery time of building project. Thus, this . Pre cast floor system could be subdivided into pre cast solid reinforced slabs and hollow core (Pre cast or Pre stressed). Construction Methods Of Cast. In-Situ Floor System. Generally, the on-site construction.

Hollowcore flooring is an efficient and modern flooring solution that can be implemented within a great many structures. Comprised of precast concrete with lengthwise voids, Hollowcore is the ideal solution for those who are looking to take advantage of the strength of traditional concrete while simultaneously enjoying a low
Hollowcore floor systems have many advantages that have made them the backbone of sustainable, durable precast concrete building components. To help reduce flooring weight for transportation, erection and foundation loading, hollowcore precast concrete planks are cast with continuous circular voids
This animation shows a simplified process of casting reinforced concrete beams and slab on upper floor level, completed with formwork and falsework. For more
The range of steel based floor systems is presented in general terms, with the advantages and disadvantages of each system identified so that these can be .. Hollowcore units: Every 2nd core broken out and filled with concrete and reinforced through the cell; Solid in-situ slabs: Concrete cast level with (or above) the top
