Assembly solutions with industrial reinforcements.
Practical example of adaptation of a project carried out in the conventional way to another carried out using industrial reinforcements.
The cost of the structure does not exceed 15% or 20% of the total cost of the works, but represents 50% of the time of its construction, hence the importance of an analysis of its execution methods.
In structures, reinforcements represent 1/3 of the cost of each m³ of reinforced concrete already placed.
Reinforcements that make up the structures have considerable differences as regards their mechanical characteristics and their nature. The same assembly can be made either from simple elements (bars), which have to be cut, produced, assembled and placed on the formwork, or with more complex prefabricated elements. In this case, the most individually hand-made work is replaced, although it is done in fixed installations, for composite products, manufactured automatically and industrialised, with the benefits that entails.
CHARACTERISTICS
Rationalisation of the reinforcements
Our Engineering Department analyses the traditional reinforcement drawings, provided by the customer, and proposes changes for the use of other manufactured in an industrialised way, easy to place in the formwork and that provide all the economic, technical, safety and environmental advantages.
The factors to be taken into account for the rationalisation of the reinforcements are:
From a technical point of view
Use assembly shapes and patterns that make it possible to use industrialised reinforcements.
Standardise, as much as possible, the reinforcements while maintaining the safety of the structures. In particular, this affects the layout of splices in areas that are not traditionally common in conventional reinforcements, and which may be high stress areas, bearing in mind the influence these stresses can have on them.
From a construction point of view
Reduce labour in production and placing, making viable reinforcements.
Change complex structures of bars and stirrups, in elements that are easy to fit on site.
Apply a regular distribution of the assembly, with the least number of bars, and larger diameters, in compliance with the conditions of anchorage, overlapping, cracking, separation and coating.
Analyse the position of the splices and the crossings of the reinforcements, so that this facilitates the placing of the prefabricated elements.
From an economic point of view
Use the most appropriate equivalent mean diameter, in accordance with is economic performance.
Steel savings, using new construction methods and new working techniques.
Use standard or industrialised reinforcements in the shop that optimise total costs of industrialised reinforcements, by reducing labour in production and placing.
