hollow core. a hollow core plank is a prefabricated slab of prestressed concrete typically used in the construction of floors and roofs in residential and commercial applications. the slabs are typically 4 feet wide with standard thicknesses of 8' and 12. the planks are produced in our plant using an ultra span machine.
less weight; the hollow core slabs are lighter in weight compared to the custom prestressed or cast in situ slabs from 37 to 54 %. thus the load transfer is reduced from slabs to beams and from beams to columns, thereby lowering the construction cost the also, we have smaller dimension for foundations.
hollowcore floors load/span table. largely because of fast on-site construction, bison hollowcore floors are one of the most economic flooring solutions for the widest variety of situations including masonry, steel and concrete structures for retail, commercial and industrial buildings.
load-span tables. the above load-span table takes into account self weight, finishes, imposed load, service/ultimate conditions, deflection and natural frequency. they are given as a guide only, please contact us on 01636 for further advice.
hollow core concrete plank bridges are highly economical and quickly constructed. when compared with the construction of traditional beam and decking bridges, the cost of a hollow core plank bridge not only compares favourably but in addition offers a far more rapid construction time. for example in the case of a regional road, hollow core concrete
hollow core slabs, or plank, are precast prestressed concrete components typically used as structural floor or roof deck systems in single and multi-story buildings. to reduce weight and provide a more efficient product, the planks are cast with continuous voids that run the length of the panel.
hollow core pre-cast concrete slabs dura-stress inc . hollow core pre-cast concrete slabs. primarily used as floor or roof deck systems hollow core slabs also have applications as pedestrian bridge deck units. hollow core is the product of choice in buildings requiring sound barriers between floors.

this technique is usually found in concrete beams, spandrels, columns, single and double tees, wall panels, segmental bridge units, bulb-tee girders, i-beam girders, flat slabs and hollow-core slabs. during post-tensioning of concrete, the compression is added following the curing process.
hollow core slab bridge deck structural behavior of bubbledeck* slabs and . 2.1.1. hollow-core slabs in the mid-20th century, the voided or hollow core floor system was created to reduce the high weight-to-strength ratio of typical concrete systems. this concept removes and/or replaces concrete from the center of the slab, where it is less useful, with a lighter material in order to
structural precast. insulated wall panels hollow core slabs precast bridge girders directly support the bridge deck and are more economical than steel girders. the durable, maintenance-free bridge product is prestressed to achieve favorable span-to-depth ratios.

our precast hollowcore slabs feature high-strength, pre-stressing stands embedded in slip formed concrete. strategically engineered longitudinal cores run the length of the slabs, reducing the overall weight. this reduction in weight not only reduces costs, but also increases the ability to handle greater loads or span greater distances.
