In this paper, a connection between precast beam and precast slabl to be used in decks of precast composite bridges is studied. The difference between this connection and the common connection used in bridge construction is that in this paper the steel connector is associated with a shear-key which is formed on the top
deck. Furthermore, it is analysed how different heat transfer models influence the overall heat transfer and heat storage in the hollow-core decks. The presented results allow comparison between detailed results from 2D-COMSOL simulations and simple 1D calculations from the whole building simulation tool such as BSim
or roof deck systems, hollow core slabs also have applications as wall panels, spandrel members and bridge deck units. by making cost comparison between the precast beam-slab system and pre-stressed hollow core slab system.

HOLLOW VS SOLID SLAB FOR YOUR DECKING. 7 Jun 2017 . For instant, there are different types of slabs like: solid slabs, hollow ribbed slab, waffle slab, and flat slab. So how does one choose the best. Advantages of Rib (Clay pot) slab over solid… 13 Jan 2017 .of the slab. The reinforcement is located between the
(Reinforced hollow-core slabs). Available in Gauteng and surrounding areas. Echo Floors provide a complete service: design, manufacture, installation and grouting of reinforced precast hollow-core concrete floor slabs. “Echo Floors” slabs are suitable for short span applications (up to 7.0m between support structures), like
In addition, the slab or deck materialises the separation between consecutive storeys and performs other functions, such as insulation between storeys, and substrate In building construction that demands speed and resistance, prestressed hollow core slab and prefabricated 'double I' pieces also have an assured future.
Whilst beams and slabs are very common in UK construction, indeed there exist a number of different basic types of composite beam, composite columns and The profiled metal decking that forms the basis of the composite slabs is sandwiched between the base of the stud and the top flange, and the welding process
Primarily used for floors and roof decks, Hollow Core is a precast slab of prestressed concrete designed for greater structural efficiency. Molin Concrete offers two types of Hollow Core plank: Flexicore and Extruded. Our product options give you the design flexibility you need while reducing your lead time.
A concrete slab is a common structural element of modern buildings. Horizontal slabs of steel reinforced concrete, typically between 4 and 20 inches (100 and 500 millimeters) thick, are most often used to construct floors and ceilings, while thinner slabs are also used for exterior paving. Sometimes these thinner slabs,
Fast in construction; No additional formwork or any special construction machinery is required for reinforcing the hollow block masonry. Disadvantages: If not properly handled, the hollow core ribbed slab units may be damaged during transport. It becomes difficult to produce satisfactory connections between the precast

A Precast concrete deck is made of precast hollow-core concrete slabs that are supported by steel beams. The disadvantage is the depth of the Also because of the differences in expansion between concrete and steel waterproofing and screeding often ends up with cracks. Construction depth can be saved using shelf
Concrete slabs are a good alternative for small extensions (where beam and block floors are uneconomic); Beam and block systems which utilise Hollow core decks are used mainly for upper floors in flats, but are ideal for cantilevered balconies, although cold bridging can be a potential design issue.

The floor slab may be in the form of a precast concrete slab or a composite slab with metal decking (either shallow or deep decking may be used). An added benefit is that some forms of shallow floor construction inherently achieve composite interaction between the beams and slab, thereby enhancing structural efficiency.
This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The reduced weight is important because it lowers the costs of transportation as well as material (concrete) costs. The slabs are typically 120 cm wide with standard thicknesses between 15 cm and 50 cm. Reinforcing
