November 23, 2010 Performance concrete for flooring June 17, 2008 Ramundo.it, the new website is online archive Panels in production The prestressed products for the construction industry are made with the use of high quality steels, which, if required, make the prestressed reinforced concrete sections entirely reactive, eliminating that concrete that in the partialized section of traditional reinforced concrete unnecessarily burdened weight of the structure, ultimately obtaining a greater load-bearing capacity of the construction components, and their smaller overall space. The hollow core slabs can be inserted in all types of structures, resting them on these, for 4-5 cm, or by fitting them to these as in the case of thick beams. The anchoring of the panel, with reinforcement reinforcement, in case it is placed, is not necessary, while it is useful in case it is stuck, Generally it is sufficient to place some iron between one panel and the next; however, it is possible to place more iron in the holes in the panel, where the concrete will flow back during the casting phase. At the request of the customer, it is possible to open, at the end of the panel, some alveoli at the top in which to arrange, if necessary, reinforcement reinforcement. This operation is done with fresh concrete on the track, and carried out by hand, therefore the opening is chipped. It should be emphasized that the concrete flowing back into the cavities during the casting creates a comb effect in the head area, which is remarkably strong, like a joint that is not realized in any other type of floor; therefore the rebound may be superfluous. THE MATERIALS - Quality assurance The materials used are the best available on the market and have the following characteristics: - Concrete with characteristic resistance of a class of not less than 550 kg / cm2, obtained with crushing stone and with cement complying with European community standards. - Harmonic prestressing steel, with a very high yield index with a characteristic working tension of 19,600 kg / cm2 and breaking values greater than 36,000 kg / cm2. The production of prestressed reinforced concrete elements is obtained by: - A fully automated batching plant, with planetary centrifugal mixer, provides concrete with constant characteristics also because it is assisted by an electronic sensor that evaluates the humidity of the aggregates used and regulates the constant water / cement ratio. - Jacks and dynamometers, checked in the run by official laboratories, ensure the excellent stringing of the steel braids on the prestressing tracks. - A vibratory finishing machine spreads the concrete in two successive layers, vibrating it, compacting it, and giving the right shape to the product. THE PRODUCTION - Controlled production Specialized technicians, in a laboratory inside the plant, continuously follow the production of the products; from the quality control of the materials used in the processing, up to the right maturation of the finished product, in its scheduled stop, on the storage areas. The laboratory is equipped with a bench, set up with a steel anchor, to perform load tests of the honeycomb panels with the possibility of studying, with appropriate cycles, the fatigue phenomenon, and also the final collapse with the breaking of the structural element. The plant's technical consultant is at the disposal of designers and DD.LL. who needed clarifications and clarifications. THE ELEMENTS Concrete cover The hollow core slab for the REI has a concrete covering of: ~ 40 mm. on the lower braids, standard, which makes it suitable for use in aggressive areas or outdoors. Finishing All the panels supplied must be considered structural elements in cap; to be covered with plaster, with stucco smoothing, with false ceilings or other. Their use in sight is at the sole discretion and benefit of the customer. The intrados is flat, the headboards and the special pieces may have irregular profiles. The manufacturer reserves the right to make any production improvements to the floors by varying some geometric characteristics and the weights of the artifacts. Tolerances - Lengths +/- 3cm; - Widths +/- 2 cm, standard pieces; +/- 3 cm, special pieces; - Average thickness in the section +/- 3%; - The panels may present some displanarity in place according to the L / H slackness. The reports The calculation reports of the panels fully comply with the requirements of the law. powered by netplanet home | about us | operating units | products | link | contact us copyright 2016 Ramundo.it VAT number 03537590717
