In the civil construction, safety and resistance are non-negotiable factors. Therefor, choosing the ideal fixation system is essential to ensure performance and structure durability. It is in this context chemichal injection anchor stands out.But after all, when to use and why to choose this type of fixation?
What is the chemical injection anchor?
The Chemical injection ancho is a fixation system that´s uses a resin to fix threaded bars or rebars to substrates such as concrete and masonry. Unlike mechanical anchors, this type of fixation does not depends on expansion to ensure firmness, which turns it with an ideal solution for dynamic load situations, Where the concrete is already cracked or in application close to the edges or close to each other. Beside being ideal for applications with high tensile loads.
When to use the chemical anchor?
- Heavy structural fixations: Ideal for elements that requires high load capacity, such as metal pillars, guardrails and industrial equipment;
- Structural reinforcement works: Excellent solution for fixing rebars in recovery and retrofit works.
- Vibrating environments: As it does not generate tension at the base, the chemical anchor prevents cracks and is recommended for fixings subject to constant vibrations.
- Applications close to the edges: As there is no mechanical expansion, it does not compromise the integrity of the concrete piece.
- Fixings in substrates with reduced resistance: Such as hollow blocks or lower density concrete, where the resistance of the fixing will be equal to the resistance of the hollow block.
