THE HOLLOW-CORE SLABS WILL BE INSTALLED BY USING A SPREADER BEAM AND LIFTING CLAMPS. MAINTAIN EYE OR RADIO CONTACT WITH THE CRANE OPERATOR. TIGHTEN AND LOCK THE SAFETY CHAIN WHEN THE HEIGHT OF THE SLAB IS LESS THAN 100 MM. DO NOT LIFT A DAMAGED SLAB.

Hollowcore planks are precast, pre-stressed concrete slabs that are generally used as flooring for both commercial buildings and homes. Floor Voids and Penetrations are available, Trimmer Beams can also be used.

As their name suggests, hollow blocks are used to fill the parts of the floor between the different T-beams. Hollow blocks are also often used in the construction of spans. When laying a composition floor, hollow blocks are placed between the T-beams. A layer of concrete is then poured over, creating a pressure layer.

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. Slabs in prestressed concrete are usually produced in lengths of up to 200 meters.

Precast concrete costs between $20 and $30 per square foot. This cost is for a 200-square-foot cast and 100-square-foot cast, respectively. This price can go down based on the size of the cast, according to the Precast/Prestressed Concrete Institute.

Beam & block floors While a simple concrete slab can be relatively cheap, it takes time to lay and dry out, so over the last few years, the beam and block suspended floor has become more prominent. It’s slightly more expensive, especially on relatively small jobs, but for speed and convenience it’s hard to beat.

Maximize space in any house plan for approximately $20 per square foot with Hollowcore Roof and Floor Systems from County Materials. Hollowcore systems are prestressed concrete plank that serve as both a readymade sub floor for a garage, and a ceiling for additional living areas.

COST OF PRECAST PANEL (NON-ARCHITECTURAL) Precast concrete panels (or slabs) will typically range from $450 to $750 per cubic yard. This is a wider range of cost because there are a wider range of options and factors affecting the total cost.

How to Install Precast Concrete Panels

1. Step 1: Plan Ahead.
2. Step 2: Get Required Permits.
3. Step 3: Build Gravel Base for Panels.
4. Step 4: Set First Panel.
5. Step 5: Set Second Panel.
6. Step 6: Seal Concrete Panels.
7. Step 7: Continue Setting Panels.

This EnCon Hollow-core Building System Design Manual has been designed to illustrate the many ways in which hollow-core precast concrete can function as a multi- purpose building system or as an integral component of a building system.

Floor slabs and steel beams act compositely together to enhance load capacity of steel beams (composite steel beams). Precast floors are manufactured on high quality steel beds and, where appropriate, are suitable for direct decoration. Exposed soffits accommodated upon request.

Pre-cast concrete floors provided excellent levels of fire, sound and noise transfer resistance. The hollow core construction also provides outstanding thermal properties. TarantoBeam and Block Floors provides a traditional and cost effective ground floor, particularly suitable to domestic dwelling, apartments blocks and extensions.

Precast concrete floor units are prestressed concrete slabs and are available as solid elements or with longitudinal hollow cores. The units are available in different depths in order to satisfy the various performance needs for span and loading. The units are normally 1200 mm wide and can be up to 20 m long.
