These profiles fit together tightly due to their clever, standardised form. For anchoring into concrete, these profiles are provided with ø10 mm, 125 mm long anchor bolts that are automatically welded on every 200 mm using resistance butt weldin

g. The top sides of the profiles are milled after being assembled to guarantee practically perfect flatness and straightness. The profiles are connected together using wing bolts with plastic nuts that do not need to be removed after being put in place. The profiles are assembled with an overlap of 15mm so that the next profile can easily be connected to the previous profile during installation. The profile is made in standard lengths of 3 m and is available in heights from 120 to 300 mm. We provide custom solutions above 300 mm. With their continuous form, these profiles prevent strain being concentrated during load transfer. This means that a higher and more smoothly load transfer is possible in comparison to discontinuous profiles. The patent pending Sinus Slide® joint with corrugated upper side in 5 mm thick steel ensures continuous support of passing wheels regardless of the direction, size and form of the wheel, from the placement of the joint to its maximum opening of 20 mm. B

y neutralising the striking impact of the wheels, forklift drivers experience unprecedented comfort. At the same time, maximum edge protection and load transfer are achieved, significantly reducing the chance of damage to the floor, the vehicle, or the goods being transported. This Sinus Slide® joint is especially recommended in thoroughfares and/or other areas of the floor that experience high forklift traffic. The Sinus Slide® Joints enables not only joint free floor slabs but the whole floor is experienced as Joint free. You can still see a joint but you don’t feel it anymore. This is a new age in industrial flooring technology. This shock-and vibration free crossing will prevent any damage on your floor and save the investor huge amounts on wear and tear of forklifts. Only with the replacement costs of wheels the payback period of the investment is less than one year.

fo@hcjoints.be page. 3 of 18 www.hcjoints.eu Technical sheet HC-Omega (SinusSlide®) armour joint Characteristics  Free horizontal expansion and contraction of the industrial floor. As the poured concrete dries, the inevitable contraction is taken up by the horizontal spreading of the HC-Omega expansion joint. This prevents the formation of cracks as a result of the drying process. This crack formation also occurs if a hole is cut into the floor too late, which is unnecessary with the installation of a dilatation joint.  Preventing vertical movement The minute tolerances between the profiles and the typical Omega form connection prevent the slightest vertical movement between the separate floor sections that are created. The steel profiles also ensure the elastic behaviour of the joint.  Load transfer With forklift traffic, the HC-Omega expansion joint provides a transfer of loads from one floor section to another. This means that the floor is less subject to wear, the ch

ance of damage is reduced, and the lifetime of the industrial floor is lengthened considerably. The Sinus Slide® version realize this load transfer is a noiseless and smoothly way. The wheels of the forklifts are sliding shock- and vibration free from one floor section to another. This creates an unprecedented level of comfort.  Maximum load. The rigid steel structure ensures that maximum loads are handled with minimum deformation.  Edge protection. The 5 mm thick steel profiles and especially the Sinus Slide® joint give maximum edge protection. The Sinus Slide® joint will not only create an unprecedented level of comfort but will also avoid any crumbling of the edges of the floor sections.  Construction joint profile The HC-Omega profiles are placed according to a layout plan with limited dimensions to separate the different floor sections. We advice floor slabs 30x30 meters in order to limit the opening gap of the joints to maximum 15 mm. The sections can then be poured a

nd finished according to the daily schedule.  Easy installation and compatible. The HC-Omega expansion joint is quite easy and quick to install according to the installation instructions given below in this technical documentation. The HC-Omega is 100% compatible with the HC-Omega Sinus Slide® Joint for every available height.  Compliant with the European directive 2002/44/EC. The Sinus Slide® joint guarantees shock- and even vibration free transfer between two floor sections even with forklifts with very small and hard wheels. With this feature the HC-Sinus Slide® Joint is compliant with the European directive 2002/44/EC concerning exposures of workers to whole body vibrations.

This indicates the

position of the load relative to the joint and support.  Fv= P x (L-A)  L o A second factor is the size of the load in proportion to the thickness of the floor. Load transfer is only provided from the moment that the load is large enough to move or deform the floor section until any play between the sections has been taken up. Small load Large load o A third factor that affects load transfer is the foundation. With a massive foundation, the loads will be supported by the foundation. In the case of a floor on piles, the load will have to be fully supported by the profile. Unstable foundation Massive foundation If a load is placed on the edge of a slab, the strain in the concrete is about 50% higher than a load in the middle of the slab. The expansion joint compensates this increase and will transfer up to 100% of this load to the adjoining slab, depending on the foundation, the position and size of the load.

Test setup It was decided to test the joint without support such that the load transfer through the joint was maximized. The joint was placed in a test specimen with dimensions 1 m x 1.05 m. The joint openings of 10 mm and 20 mm were tested. For the concrete, a test was done with non-reinforced concrete (c30/37) and with fibre 3 reinforced concrete (45 kg fibres/m ).
