Production of reinforced cages and main connections
The precast factory often has specialist workshops for the manufacture and maintenance of moulds, and for the production of jig-built reinforcing cages and connections.
0202
Assembly of moulds
The reinforced cage is positioned in the partly assembled mould, then the remaining mould section is completed.
0303
Mix being poured
Carefully specified concrete is placed into the mould. Many precast works now employ computer controlled batching plants.
0404
Compaction of concrete using poker vibrator
To ensure that optimum density is obtained and that specified strengths are achieved, concrete is placed and compacted using high-frequency external vibrators or pokers.
0505
Precast concrete being moved to the storage area
Once an appropriate strength has been reached, the precast units are moved to the
storage area. Units are usually handled within hours of casting as part of the rapid
production cycle.
The product exhibits a high degree of dimensional accuracy and quality of finish.
Economies of production are achieved through the repetitive and automated process.
0606
Storage of high-quality units in works area
The finished precast components are stacked on clean battens or plastic pads positioned to suit the design of the component. Care is taken to keep the stacks vertical and to ensure that battens are placed directly above one another within the stack.
