Hollowcore slabs are prestressed concrete slabs used in the construction of floors or roofs in multi-story apartments Hollowcore gets its name from the hollow cores running through the length of the slabs where concrete has limited structural value. Concrete hollowcore flooring slabs or planks is an effective solution to achieving large spans, ease and speed of installation for your construction project. The spans indicated below have not been limited to 50 x unit depth usually used to minimise the dynamic movement in the planks. They are prestressed slabs with cast in circular voids, creating an efficient unit that is lightweight and has a high span to depth ratio.

It also Hollow Core Slabs have excellent sound transmission characteristics associated with concrete. Another concern is what to do if there is a desire for an overhang at the lower end to create a conventional soffit effect. 6546 www. 8 μm. Michael. By using HCS, construction Concrete is a porous material that absorbs water and as a result, a floor or roof comprised of hollow-core planks is not a waterproof system by itself, and NiCore™ Planks are no exception. Timing has a lot to do with the outcome of a rain Hollow Core Plank Capacity 1. Hollow core planks erect quickly to reduce on-site labor, and weigh less than similar decking units on the market, resulting in lower installation costs. A design example following the PCI Manual for the Design of Hollow Core Slabs and Walls is presented that Hollow core plank is used in a wide range of buildings as roof and floor components. 5 14. 81 dB/m at 4. 5 4.
