Hollowcore Slabs

1.1 Hollowcore Slabs One of the most advanced precast products. Millions of square meters of hollowcore slabs are used every year in the building constructions all over the world (villas, multistorey buildings, car parks, schools and shopping malls, etc.) where high quality control and safety standards are guaranteed at the Precast Plant. Hollowcore slabs are used mainly for flooring and roofing, but can also be used for wall purposes. Hollowcore slabs give the following advantages : a.) Lighter compared to equivalent cast in situ solid slab,thus material savings in design of all structural components b.) Provide excellent fire resistance and sound resistance c.) Smooth and excellent soffits for painting works d.) Fast erection, thus savings in time and manpower e.) Designed according to ACI, PCI and CPCI international codes f.) Overall savings in Time, Labor, Shutter ing, Scaffolding & Building Materials Bina standard slab types are 150mm, 200mm, 265mm, 320mm, 400mm and 500mm deep with 1200mm width

As specified in ACI 318M-08 16.6.2.2-(a) Each member and its supporting system shall have design dimensions selected so that after consideration of tolerances, the distance from the edge of the support to the end of the precast member in the direction of the span is at least Ln/180 but not less than; For Solid or Hollowcore Slabs.............. 50 mm For Beams or Stemmed Members ....... 75 mm

The nominal Length of simply supported Hollowcore floor units is given in the table.

1.5 Typical Connections Details

Holes in the Hollowcore slabs are made as indicated in the cross section drawing. Small holes are limited to the width of the voids. Small holes are usually made on the erection site. Big openings are made to the fresh concrete during production process.

1.6.1 Large Openings Hollowcore Slab

The size of large openings depends on the span and the load required. Location of the holes are indicated in the drawing. Large openings, which are larger than the slab are supported by steel headers.

Penetrations and block-outs in slab should not cut through the strand unless these have been allowed for in the design (Figure A). Any coring on site should be restricted to defined parts of members. Where large penetrations are required, full width headers (Figure B) may be used to support the end of a slab and transfer the load to the adjacent slabs. These slabs must be designed for the additional load. Figure (A) Penetrations Positions

Applications requiring close control of differential camber between adjacent members of the same design should be discussed in detail with the producer to determine applicable tolerances.

1.8 Transport and Erection Clear access for delivery trucks and mobile crane is necessary for the erection of Hollowcore slabs. Erection procedure is executed in accordance with the design layout to ensure an uninterrupted continuous operation. Hollowcore slabs are placed directly on their places with shims for leveling and grouting purposes. Hollowcore slabs are lifted with specially designed clamps hanging on a steel spreader.

Wall Elements

2.1 Wall Elements Bina Precast produces wall elements with the latest technology, machineries and know-how. Wall elements like sandwich (insulated) panels, cladding panels or solid walls (load bearing or non-load bearing) are produced on horizontal, flat-steel surfaced tilting tables. Precast Concrete Wall Panel system gives the following advantages : a.) More freedom for architectural design b.) Economical, low maintenance cost due to its excellent quality concrete c.) Unique visual appearance and image for the building due to availability of widerange surface options d.) Can be used for all types of building like villas, multi-storey buildings, car parks, schools and shopping malls etc. e.) Electrical conduits and other required cast in parts can be incorporated into the element during production stage. f.) Fast erection, thus savings in time and manpower g.) Higher quality control & safety standards are guaranteed at the Precast Plant h.) Designed according to ACI, PCI and CPCI international codes i.) Overall savings in Time, Labor, Shutter ing, Scaffolding & Building Materials

2.2 Sandwich Panels Panels are made of two layers of steel reinforced concrete separated by insulation material. Insulation material (extruded polystyrene, etc.) provides a low thermal U-value and improved sound insulation properties. Two concrete layers are connected together using stainless steel girders or pins.

Panel elements are delivered to the erection site by A-frame trailers and erected to its place by mobile or tower crane. External surface option can be gray, white or colored concrete. Surface finishing can be smooth for painting, exposed aggregate or sand blasted. Bina Precast tilting tables provides and ensures high quality product for Customers satisfaction and elements as required for the erection needs.

2.3 Cladding Panels Panels are solid concrete units architectural finishing. Elements are used as wall panels for facing the building.

2.4 Solid Wall Panels Panels are used as part of the building system for load-bearing walls or non loadbearing walls.

Columns & Beams

5.2 Beams / Prestressed Precast Prestressed Beams are produced in different sizes and shapes (rectangular beams, inverted T-beams, L-shape beams and I-shapes beams).

5.2.1 I-Beams I-beams are used for floor beams where heavy loading and large spans are required, but can be used also for roof structures.

5. Columns & Beams

5.1 Columns

Precast concrete columns and beams provide advantages in designing buildings for shopping malls, schools, warehouse etc.

Precast columns are produced in different sizes and shapes.

Long span precast columns and beams provide benefits for large open area structure. Precast beams can be designed and produced using ordinary reinforced concrete or prestressed concrete. Precast components are delivered by trailers to the erection site for installation.

30

Typical PC Column - Footing Connection Details:

Rectangular column size varies from 300mm to 600 x 600mm (or as per Structural Design Requirements) Precast columns are fixed to the foundations with pockets, projecting reinforcing bars or holding down bolts, the first solutions is mainly used for foundations of good soil; the second and third in the case of foundation piles.
