What is bondek formwork?
The original name in steel formwork, BONDEK® is an efficient, versatile and robust structural decking and ceiling system for concrete slabs. It is a highly regarded formwork product offering efficiency and speed of construction.
How thick is a bondek slab?
BONDEK PLUS® comes in a variety of thicknesses: 0.60mm 0.75mm, and 1.00mm and provide 550MPa of yield stress strength. This inherent strength means BONDEK® offers top of the class spanning capacities. Embossed ribs at 200mm centres add to the structural and bonding strength with the concrete.
How is bondek made?
bondek profiled steel decking is roll-formed from hot dipped, zinc-coated, hi-tensile steel strip, in base metal thicknesses (bMt) of 0.60, 0.75, 0.90 and 1.0 mm. the steel strip conforms to as1397 grade g550, Z350.
Why is the bondek Coloured blue?
BlueScope Lysaght’s Senior Design Engineer, Con Papageorgiou says, “We produced LYSAGHT BONDEK BLUE® in response to industry concern about glare, when working with steel formwork.
Is bondek fire rated?
The performance of BONDEK has been improved from recent analysis and confirmatory testing for formwork spanning and fire design. Most suitable for thin slabs up to 120mm. Slab can be designed for fire rating of up to 90 minutes without additional fire reinforcement.
What is metal deck?
In the construction industry, the term ‘metal decking’ covers all forms of the profiled steel sheeting commonly used together with concrete and steelwork to create a composite floor system or as a structural element to support a built-up roof system.
What is suspended slab?
Suspended slabs are slabs that are not in direct contact with the ground. They form roofs or floors above ground level. Suspended slabs are grouped into two types: one way slabs which are supported on two sides. two way slabs which are supported on all four sides.
How is a suspended slab made?
Suspended slabs are made of concrete and steel mesh, the same as a ground slab. Some slabs have hollow channels running through them – these ‘hollow core slabs’ are used to help reduce weight, and also to allow cabling and piping to be run through the slab.
How is a suspended slab built?
Precast concrete suspended slabs are constructed off site and later are craned into the construction site. This type uses precast concrete panels or planks spanning only in one direction. The concrete is poured after the reinforcement is placed in reusable and adjustable moulds.
What is BMT bondek?
An advancement of the original name in steel formwork, BONDEK® II is an efficient, versatile and robust structural decking and ceiling system for concrete slabs in conventional as well as composite slab design. Excellent spanning capacities for greater strength and less deflection.
