Thermal and Sound Slab Overview. Prestressed hollowcore slab is predominantly used on first and subsequent floors, though with the additional thermal properties we achieve slabs are increasingly installed at ground level. These 1.2 metre wide slabs can span up to 9 metres depending on the load applied.
A hollow core slab, also known as a voided slab, hollow core plank or simply a concrete plank is a precast slab of prestressed concrete typically used in the construction of floors in multi-story
Hollow Core Slab Techical Sheets. Hollow Core Technical Sheets should be used for guidance only and consultation with Hollow Core Concrete should be made prior to proceeding.
This type of through girder structure with a solid slab continued to be illustrated in design texts well into the 1930s Figure 19 . The 1939 text Reinforced-Concrete Bridges noted that "the simplest design of floor construction for a through bridge consists of a slab spanning between the main girders."
The precast concrete slab has tubular voids running the full length of the slab, making the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. In the cross section of hollow-core slabs, concrete is used only where it is actually needed.
Hollow Floor Slab 1. HOLLOW FLOOR SLAB 2. A hollow core slab refers to a precast slab that is prepared using prestressed concrete. It is generally used in the construction of floors for high-rise apartments or multi- storey buildings. 3.
Prestressed Hollowcore concrete flooring manufactured by Creagh Concrete in Northern Ireland and available throughout the UK and Ireland. Slabs can be designed
Hollow-core slab - Wikipedia, the free encyclopedia This makes the slab much lighter than a massive solid concrete floor slab of equal , The slabs are typically 120 cm wide with standard thicknesses between 15 cm , of precast hollow-core slabs and walls can be made by different extruders.
I'm in the process of converting a car port into a garage and have discovered the ground under the poured concrete floor slab may have dropped. The garage is 48 years old and is in an area susceptible to subsidence big pine trees surrounding the house . One half of the slab sounds hollow when hit with a hammer.
In addition to our beam and block range of flooring, we also manufacture precast concrete hollowcore flooring units. These units are a prestressed concrete slab normally 1200mm wide part widths are also available if required and a current depth range of 150mm to 450mm. In addition to this range, we also manufacture a 100mm deep solid slab.
hollow-core slabs. Applications covered include floors, security walls, reservoir roofs, retaining walls and warehouse walling, multi-storey floor applications to residential, commercial and industrial buildings, as well as suspended ground floor slabs in clay areas and a foundation system for social housing. Services offered:
Hollow clay pot slabs are usually constructed with fewer concrete and reinforcement compare with solid slab. Hollow blocks are used to fill portions of the slab thickness; this results in deeper the amount of concrete and hence the weight of the slab.
Discover precast hollow core concrete flooring from Milbank in Essex. Strong, versatile, cost-efficient concrete slabs for buildings in residential, commercial, and educational settings. Designed and made in the UK with quick supply to areas including London and the Home Counties.
The thermal performance of standard OReilly Hollowcore floor slabs is 25% better in average com- paring to the same slabs with open voids. THERMAL MASS EFFECT Thermal mass is a property that enables precast concrete floors to absorb, store, and later release significant amounts of heat.
FloorCAD is the software of choice for the design, layout, production and dispatching of precast concrete slabs. This intelligent software reduces the slab cost per unit area with seamless integration to every part of the production process.
Hollowcore concrete slab is a versatile precast element. Hardly any building materials available today offer the economy, flexibility and reliability of precast, prestressed concrete. Hollowcore advantages The advantages of Hollowcore slabs. There are several advantages of the precast hollow core slab or prestressed hollow core slab such as:
Concrete Hollow Core Floor Slabs Hollow core slabs are precast, pre-stressed concrete elements that are generally used for flooring for both commercial buildings and homes. Some of there advantages are as follows:

The prestressed floor slabs are used where the loosely reinforced slabs are close to their limits, with regards to load and span width. The width, depending on the production procedure, is up to 3 m, thickness of the concrete board is 80 - 120 mm.
Compared to the hollow core slabs in reinforced concrete, which were 60 cm wide and up to 6m long, the pre-stressed concrete floor slabs usually were wider and longer. An example of the latter is the Ergon SP-floor slab.
All floors consist of a solid prestressed slab acting as fully participating formwork which may be propped or unpropped depending on design requirements and which act compositely with an in situ topping to form an efficient structural section.
The widest composite prestressed flooring slab available. A unique precast concrete flooring product from Flood Precast. At 2.4 metres in width, this is the widest composite prestressed flooring slab available anywhere.
A hollow core slab, also known as a voided slab, hollow core plank or simply a concrete plank is a precast slab of prestressed concrete typically used in the construction of floors in multi-story apartment buildings.
Two-way slab action is assumed in a ribbed floor slab with joist beams made of the precast double-tee section, in the ribbed floor with integral beams, and also in hollow-block or hollow-cored slabs.
