The challenge of construction joints for
industrial flooring

COSINUS SLIDE® ENSURES EFFICIENT CONTROL OF BOTH STATIC AND VOLTAGE LOADS
DYNAMIC AND A PASSAGE OF TROLLIES WITHOUT LOCALIZED SHOCKS AND BREAKAGES IN
CORRESPONDENCE OF CONSTRUCTION JOINTS

The growing demand for logistics platforms has encouraged research in the field of industrial concrete flooring, as this is one of the most important components of an industrial building. The professionals of the
sector over the years have paid increasing attention to the issue of industrial flooring and in particular to construction joints due to the delicate role that the latter play. As regards construction joints, which we can define as lines of discontinuity in the concrete floor determined by the limits of daily productivity for the creation of the castings

there has been a rapid evolution over the years, moving from simple sheathed bars to real prefabricated devices that integrate the function of load transfer with that of protection of the concrete near the edges of the joint. In fact, the construction joint is invested with the dual antithetical function of allowing, on the one hand, the freedom of movements due mainly to the shrinkage and flow of the concrete and, on the other, ensuring the
elastic congruence between the parts adjacent to the construction joint ensuring its continuity and perfect coplanarity. This function is performed in a complete manner the higher the capacity of
load transfer of the construction joint. The innovative design of the Cosinus Slide® construction joint patented by Hengelhoef Concrete Joints (HCJ) and distributed in Italy by CPRGIUNTI, offers a dual response to the performance requirements of a construction joint. Cosinus Slide®
revolutionizes the concept of static and dynamic load transfer by moving from the traditional discrete scheme using bars or plates to a continuous scheme in which the floor itself acts as a construction joint. In fact, Cosinus Slide® creates a continuous shelf designed by a surface sinusoid sliding on a lower cosinusoid. The transfer efficiency of this type of configuration reaches values ​​that largely exceed 40%. The special shape of the exposed sinusoid has been designed to achieve a significant reduction in noise when trolleys with rigid wheels pass and at the same time to preserve the integrity of the
concrete along the development of the sinusoid in sight.
