Cosinus Slide® joint patent pending THE ROXELER ENGINEERING MODEL as guideline for designing Industrial ﬂoors using the Cosinus Slide® technology www.hcjoints.eu 2 X 5 mm SINUS CONTINUOUS ANCHOR SYSTEM CONCRETE OVERFLOW BARRIER DOUBLE COSINUS ADJUSTABLE STEEL PLATE The Cosinus Slide® joint enhances the basic principles a designer has to comply with: securing the stability and the ongoing usability of the ﬂoor STABILITY VERIFICATION Thanks to the Sinus-Cosinus geometrical shaped form of the joint and the concrete, load transfer is not realized by the joint but by the ﬂoor itself. Each sinus corrugation on top is opposed by a cosinus corrugation underneath. These staggered arranged sinus corrugated steel plates shape small vertical reinforced concrete consoles over each other. The load bearing of these columns determines the load bearing capacity of the complete ﬂoor. STABILITY CALCULATION ON REQUEST. ONGOING USABILITY OF THE FLOOR The Cosinus Slide® joint satisﬁe

s the requirements of ﬂoor usability such as shock- and vibration free joint crossings regardless the speed of forklifts. This feature generates extended advantages in the ﬁeld of: Environment Durability of the ﬂoor Healthcare and well-being at work enhanced proﬁtabitability of operators and cost savings www.hcjoints.eu Where theory meets practice THEORY The European standard EN 1991-1-1 takes for granted wheel loads of 13kN until 85kN. The standard also assumes wheel contact surface of 20 x 20 cm which represents pneumatic tyres. The contact pressures and the corresponding shock impact of this type of tyres on a linear proﬁle is minor or even negligible. PRACTICE However, in reality small hard synthetic wheels (vulkollan, polyamide) are used which are not included in the European standard EN 1991-1-1. These types of tyres causes heavy shock impacts on linear proﬁles which will damage the ﬂoor, the joints and the forklifts. The tendency to increase speed of forklift

traffic makes it even worse. THE ROXELER ENGINEERING MODEL eliminates these problems and secures the stability and ongoing usablity of your ﬂoor ONGOING USABILITY by minimum 2x5mm sinus edge protection STABILITY VERIFICATION Cosinus + Sinus = h2 + h1 h1 h1 h2 Forklift category Wheel load Qk Contact area 200x200mm kN h2 Stability veriﬁcation Pneumatic tyres 200x200 mm Cosinus+Sinus Stability veriﬁcation Synthetic tyres 20x100 mm Cosinus+Sinus h2 + h1 in cm min. h2 + h1 in cm min.
