Masa WhiteHub provides AAC manufacturers with a state-of-the-art plant concept, featuring efficient control systems and a high level of automation.In April, the bauma in Munich will once again provide the international construction machinery industry with a platform for profitable innovations and cross-border exchange. Masa WhiteHub, as part of the Masa family, will be focusing on the topic of reinforcement in one area of the exhibition stand, among other things.Depending on the desired range of reinforced AAC products (lintels, partition wall panels, wall panels for cladding, load bearing wall panels, panels for flooring/ceiling etc. or a combination of these) and their respective capacities, Masa WhiteHub can offer solutions ranging from simple (mostly manual or semi-automatic versions) to highly sophisticated fully automatic reinforcement systems. Attention must be paid to the reinforcement steel itself and to the handling system for the reinforcement.The reinforcement steelThe first step is to manufacture the appropriate reinforcement steel itself. Both the individual reinforcement parts, such as bars, meshes or cages, and the spacers have to be considered.Variants of the reinforcing partsAt the beginning, several possible variants for the specific reinforcement parts are discussed and defined together with the customer and potential reinforcement machine manufacturers:Variant 1: The customer can start, for example, with steel reinforcement bars. These can be purchased tailor-made or produced by the customer. If the customer only wants to produce partition wall panels, for example, only rods/reinforcement bars (so-called %u2018wires%u2019) are sufficient as reinforcement.Variant 2: If steel mesh is required for reinforced products, the customer can have it welded together manually or opt for a machine-based (semi- or fully automatic) production process. With a machine-based solution, the customer can choose between starting with reinforcement bars (if the desired capacities allow) or with coils.Variant 3: For even more heavily loaded reinforced products, reinforcement cages are required. These can also be hand or machine welded. If machine-welded, the customer can again choose whether to start from reinforcement bars (if capacity allows) or from coils. In many cases, several (separate) machines are required to produce the reinforcement cages in several stages. Various suppliers also offer highly automated systems in which the reinforcement cages are completed in one step.Whichever variant is choosen, there is one important requirement: every weld has to be performed in accordance with the specifications for reinforced AAC products.Plus, the reinforcement mesh or cage has to be designed and calculated for each desired product, ac-
