Slab rehabilitation is key to ensuring structural safety in deteriorated buildings. Among the most effective solutions is structural reinforcement with mechanobeams, an innovative system that offers minimal intervention and excellent results without the need for major construction work.
Thanks to its ability to integrate with different materials, this method has positioned itself as one of the preferred techniques for restoring beams in old homes and buildings.
What is structural reinforcement with a mechanobeam?
Origin and evolution of the system
The mechanobeam emerged in the 1990s as a response to the most common structural problems in slabs. Over time, its use has spread due to its effectiveness, adaptability, and speed of installation, becoming a benchmark among reinforcement solutions.
Components of the telescopic mechanobeam
This is a metal structure with a steel sheet profile and bolted joints that require no welding. Its telescopic design allows it to be adjusted to the exact length of the beam to be reinforced, ensuring stability and strength.
Pathologies that it corrects
Structural reinforcement with mechanobeam is effective in a wide variety of structural pathologies, such as:
- Wooden beams: affected by termites or humidity.
- Metal beams: with oxidation processes.
- Concrete beams: with aluminosis, carbonation, presence of chlorides or sulfates.
How does the mechanobeam system work?
Preliminary analysis and preparation of the beam
Before any intervention, an inspection is performed to diagnose the condition of the beam. The surface is then cleaned, and any damaged areas are removed to ensure proper application of the system.
Telescopic mounting and anchoring
The telescopic metal structure is adapted to the beam by means of brackets and the application of special resins. This system restores the mechanical stability of the original beam.
Load transmission and reinforcement
An internal metal cable allows for the transfer of tensile loads, reinforcing the structure and complying with structural safety regulations. The result is a robust and long-lasting solution.
Advantages and applications
Quick installation without invasive works
One of the greatest advantages of structural reinforcement with mechanobeams is its rapid installation, which doesn't require evacuating the home or major interventions. It's ideal for inhabited buildings.
High durability and resistance to aggressive agents
This system offers excellent resistance to:
- Corrosion and oxidation.
- Carbonation of concrete.
- Chemical and climatic agents.
Furthermore, it is approved and meets the technical requirements for its application in building structures.
Common use cases
It is recommended for pathologies such as:
- Aluminosis.
- Carbonation.
- Active forgings.
- Attacks by sulfates, chlorides or termites.
Step-by-step installation process
Structural inspection and calculation
The project begins with a technical diagnosis of the structure to calculate the dimensions, loads, and degree of deterioration. This allows for precise reinforcement design.
Fixing of brackets and telescopic assembly
Thick metal brackets are installed to provide additional support, and the telescopic profile is adjusted to the exact dimensions of the beam.
Application of repair and validation mortar
The damaged area is filled with technical mortar to restore the structural section. Once hardened, tests are performed to verify its safety, and the final finishes are applied.
Comparison with other systems
Compared to traditional metal profiles
- The mechanobeam minimizes water consumption and allows for cleaner assembly.
- The traditional system usually requires more time and greater intervention in the original structure.
Carbon fiber front
- Carbon fiber adapts better to uneven surfaces but is more expensive.
- The mechanobeam is more resistant to extreme temperatures and high loads.
Against welds and steel plates
Advantages:
- Firm and durable union of different materials.
- High structural penetration.
- Effective treatment of deep pathologies.
Disadvantages:
- Requires qualified personnel.
- Thin metals can be deformed.
- Higher cost in some cases.
