Hollow core is what every property developer is choosing now-a-days to make constructions cost effective, efficient and easy. The hollow core slabs are the basic construction elements made from prestressed concrete. They may be used for construction of roof, floors or walls in the multistoried constructions such as apartments, high rise office/industrial buildings and so on.
There are number of ways through which hollow core concrete planks are produced in concrete production facilities. Nevertheless the two basic methods employed in most of them are extrusion and slip forming. The common factor about these methods is that both of them make use of casting beds where the slabs are formed on top of seventy to two hundred meters lengthy casting pallets.
Hollowcore Manufacturing
The hollowcore slab manufacturing process starts with preliminary preparation of the casting beds followed by series of steps including pulling and affixing the pre-stressing cables or strands to the concrete, pre-stressing the concrete, developing the slab round the reinforcement, marking and identifying the slabs, curing of the slabs, shaping the slabs to required lengths, drilling the drainage holes and last but the least lifting and conveying the slabs to stockyard.
Hollow Core Production Equipment
Different types of hollow core machinery operate in manufacture of precast hollow core elements. A few of the fundamental machines used in process include the slab extruder, slab cutting saws, erecting and lifting equipment as well as casting bed maintenance equipment.
Hollow Core Extruder
The job of an extruder in a hollowcore manufacturing process is to cast slabs. An extruder machine is responsible for framing out slabs of preferred dimensions from the prestressed concrete mix in casting beds. Dosing, forming, compacting as well as finishing of the slabs all of the tasks are possible to execute on a single extruding device. The quality of slabs produced depends on compaction of dry cast concrete and this compaction feature in turn depends on frequency of vibration of this machine. Frequency of vibration of this hollow core machine makes the concrete particles circulate and allow uniform slab production that or else will be a challenging procedure due to absence of drinking water.
Hollowcore Saw
After the slabs are casted through extruders, they are reduced to the needed dimensions as well as shape using special slab cutting saws. Different types of slab cutting saws are employed in the hollowcore manufacturing process such as cross cut saws, rip cut saws and angle cut saws. The modern cross cut as well as angle cut saws tend to be sophisticated machineries which offer secure as well as efficient operating system to the producers allowing them to cast slabs of almost any form and measurements.
Hollowcore Lifting Equipment
After the manufacture of slabs they're erected and lifted off the casting bed and then transported to the stock yard for storage. These are usually really large and heavy and cannot be raised by manually. Therefore instead of manual force these are lifted by the lifting beams or clamps. These types of slab lifting tools can help in swift and efficient conveyance tasks at the slab production units.
