GUIDELINES
Guidelines for Quantity and Maximum Permissible Spacing Between Adjacent Gupta Concrete Spacers.
The following recommendations are based on our observations and analysis across various construction sites. These guidelines ensure proper cover to reinforcement and assist site engineers in estimating and procuring the appropriate quantity of spacers prior to concreting.
| Structural member | Diameter of rebar | Permissible distance | NOS. Required |
|---|---|---|---|
| Slab | 10mm | 50 cms 70 cms |
4per m2 2 per m2 |
| Beam | 10mm 10 to 16mm above 16mm |
50 cms 100 cms 125cms |
2 per meter 1 per meter 0.8 per meter |
| Column | 12mm 10 to 20mm above 20mm |
25 cms 50 cms 80 cms |
4per meter 2 per meter 1.25 per meter |
Important Note
For heavy multilayred reinforcement kindly work out the number of spacers requried, by using the maximum load bearing capacity of individual spacers as against the weight of reinforcement. For this purpose please refer the breaking load data of every spacer given in the technical specification tables mentioned on above.
