A Toyota Manufacturing Plant: Comparing traditional straight joint to HC-Omega Sinus Slide® - 2011
In this video we are watching the difference in sound and ware of the concrete joint in a Toyota assembly plant. This video was taken in 2011 and the HC-Omega Sinus Slide® joint was placed here in 2007. With over 42 million crossings then, today this joint is carrying over 84 million crossings and counting.
Cosinus Slide® Steel Armored Joint Follow Up On Several Facilities After Years Of Intense Service
This video features follow up visits to several industrial facilities, where HCJ Cosinus Slide® armored joints were installed. A Toyota parts distribution center in Belgium after nine years of continuous service. A Rewe logistic center in Germany after 4 years. And Essers logistic center in Belgium. All these facilities' floor joints are in perfect condition after years and years of intense material handling traffic.
All of these clients have written testimonials confirming the savings and long term benefits of the Cosinus Slide joint.
Both longitudinal and latitudinal free movement of the slab
Concrete shrinks as it dries forcing a gap at some point in the slab. By designing a gap in the slab using our durable and robust steel armor expansion joints, the concrete will naturally shrink and the joint will take up the shrinkage of the concrete. Our joints allow for free expansion and contraction while allowing the slab to freely move side to side. Our continuous load transfer steel armor joints allow for free horizontal movement of the slab.
Mitigating Vertical Movement
One of the biggest problems to concrete slabs is their vertical movement as large dynamic loads move from slab to slab. Differential in height of slabs causes damage to wheels, merchandise, the MHE operator, and to the slab edges. Our armor joints solve this problem of vertical movement while provide continuous sheer load transfer through each of our armor joints. Your concrete slab edges will be more durable and robust, the wheels will last longer, and your facilities work place will improve.
Optimal Load Transfer
Whether loading is static such as racking and machinery or dynamic such as MHE and cat tracked equipment these armor expansion joints transfer extreme loads up to 20kips per foot, depending on the implementation and the depth of the slab. With dynamic loading we recommend the Cosinus Slide® or the HC-Omega Sinus Slide® as this provides a very smooth and quiet load transfer from slab to slab as seen in the Cosinus Slide joint video.
Saw cut joints will eventually deteriorate and spall with continuous traffic crossings. This is due to the straight gap which has no load transfer allowing the dynamic load to vertically move the slab. Each round wheel will fall into the gap formed by the saw and damage the edges of the slab. This phenomenon of spalling plagues nearly all concrete slabs. However, with our armor edge joints, spalling is mitigated because of the continuous load transfer and the 0.2 inch (5mm) thick armored edge which is standard on all of our expansion joints.
