PSCS Fully Adjustable Bollard Embed Specially Made For Freezer Slabs.

Our adjustable height, from 5-1/2 - 9-1/2" thick slabs, makes matching the embed to the slab thickness extremely easy. Bollards are used to protect various building and racking elements from potential damage. By first casting a bollard embed into the floor, the bollard should then fail at or just above the weld. Making for easy replacement of the bollard, while preserving the concrete floor.

Before and after video of floor joint - HCJ Sinus Slide® repair joint

This is a very busy baggage operation where the floor joints were experiencing continued deterioration even after multiple repair attempts.

The Problem: The continued impacts from the wheels were the culprit. Prior joint repairs did not address this culprit. Rather, they only attempted to fix the symptom, the spalled out joints.

The Solution: The HCJ Sinus Slide® repair joint has a unique 2 x 5 mm sinus wave shape. This unique sinus wave geometry is not realized by the wheels themselves when crossing the joint. By eliminating the culprit, this best assures a sustainable solution.

Important: It must be determined that a known and adequate load transfer system is in place.

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 heavy continuous service. A Rewe logistic center in Germany after 4 years. And Essers logistic center in Belgium. All these facilities' floor joints are in excellent 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.

PSCS HCJ Sinus Repair Joint - Repair Process

In today's modern environment, almost all MHE fleets are electric. This means that the wheels are extremely hard and small, which often wreaks havoc on floor joints. Due to these small hard wheels, traditional joints have a hard time holding up in such high traffic facilities. It is not uncommon for joints to continue to deteriorate even after they have been repaired.

The Sinus Slide® repair joint has a unique 2 x 5 mm sinus wave shape. The sinus waved shape of the joint itself is not realized by the MHE wheels when crossing the 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.

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.

Mitigating Spalling

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.
