In the world of construction, the importance of ensuring concrete cover under steel bars cannot be overstated. Traditionally, ordinary cover blocks have been used for this purpose. But they often fall short in providing the fixity required to withstand the challenges of modern construction. They lack a system to securely bind themselves with steel bars. This leads to their displacement during casting due to factors such as human movement, vibrations from vibrators, and the flow of concrete.
CROSS LOCK Spacers & Rebar chairs also called PVC Cover Blocks, addresses these challenges and sets a new standard in construction. Let’s explore the advantages that make CROSS LOCK spacers the preferred choice for builders and engineers.
Best Fixity with Steel Bars
One of the standout features of CROSS LOCK spacers is their ability to securely lock themselves at the crossing of two steel bars without the need for binding wire. This ingenious design ensures that the blocks remain firmly in place throughout the casting process, even in the face of human movement, intense vibrations, and the continuous flow of concrete. The result? A hassle-free and reliable solution for maintaining precise concrete cover under steel bars.
Enhanced Stability
CROSS LOCK spacers go a step further by offering both linear and rotational stability. This means that not only do they stay firmly in place, but they also resist any unwanted movement or rotation before and during the casting process. Builders and engineers can trust that their structural elements will remain exactly where they are intended to be.
Impressive Load-Bearing Capacity
With a remarkable load-bearing capacity of about 400 Kg, CROSS LOCK spacers are more than capable of handling the stresses imposed by repeated human movements during casting. This high load-bearing capacity adds an extra layer of reliability to your construction projects. It ensures that the integrity of your structures remains intact.
Homogeneous Concreting
The hollow structure of CROSS LOCK spacers, boasting over 60% void area, is a game-changer. It allows for the efficient flow of concrete, resulting in homogeneous concreting without the dreaded cold joint formation. This means that your structures are not only stronger but also more aesthetically pleasing.
Meets & Exceeds requirements of codes
As per Indian building code IS 456 : 2000 under section 12.3.2 “Spacers, cover blocks should be of concrete of same strength or PVC.” British standards BS:79673 – 2001 on Spacers and chairs for steel reinforcement states that if material is non cementious then at least 25% area under its periphery should be void. Cross lock spacers and rebar chairs meets and exceeds these requirements.
Long-Term Cost Efficiency
While there may be an initial upfront cost associated with choosing CROSS LOCK spacers. But the long-term cost-efficiency they offer is undeniable. Thanks to their superior durability, load-bearing capacity, and resistance to movement and rotation. These cover blocks ensure that your construction projects stand the test of time. This means fewer maintenance and repair expenses down the road, ultimately saving you money in the long run. The initial investment in CROSS LOCK Cover Blocks pays off handsomely in terms of reduced lifecycle costs and enhanced project longevity.
Conclusion
In conclusion, CROSS LOCK Cover Blocks represent a significant leap forward in the world of construction. They provide unmatched fixity, stability, and load-bearing capacity while ensuring homogeneous structure and flawless finish. Say goodbye to the hassles of ordinary cover blocks and embrace a new era of construction excellence with CROSS LOCK Cover Blocks. Your projects deserve nothing less.
