Description

Getzner High load elastomeric bearings (Sylodyn® HRB HS) are state-of-the-art solutions engineered for use in modern building construction. These bearings fulfill a dual purpose: they facilitate the safe, targeted transfer of concentrated structural loads (up to 12 N/mm²) under critical elements like columns, walls, and pile foundations, while simultaneously providing reliable protection against disruptive vibrations and shocks.

Made from the high-performance material Sylodyn® HRB HS, these bearings achieve an optimal tuning frequency of between 8 Hz and 12 Hz, effectively isolating the building interior from external influences such as road or rail traffic noise. Their targeted application makes them an economical choice for achieving superior dynamic performance without compromising structural integrity.

Product Variations and Applications of High load elastomeric bearings :

Gitco-sa.com offers the complete range of Getzner’s high-load elastomeric bearings in various forms to suit all construction requirements:

• Point Bearings: Designed for transferring concentrated individual loads directly under supports, offering high load-bearing capacity and local vibration isolation.

• Strip Bearings: Used under load-bearing walls for uniform load distribution and easy integration into masonry or concrete structures.

• Special Bearings for Pile Foundations: Custom solutions for the elastic decoupling of pile heads, supplemented with filler material for complete load transfer in dynamically loaded foundations.

Key Applications of High load elastomeric bearings :

• Column and Wall Isolation: Inserting bearings under structural columns and load-bearing walls to locally decouple concentrated forces from the foundation.

• Building Base Isolation: Used in conjunction with other systems to protect entire buildings constructed in areas exposed to heavy railway or road traffic vibration.

• Vibration-Sensitive Structures: Isolation of specific zones or floors in hospitals, research facilities, and high-tech manufacturing plants requiring an ultra-stable environment.

Know More about Getzner High-Load Elastomeric Bearings:

1. What are Getzner High Load Elastomeric Bearings?

   They are specialized, high-performance elements made from polyurethane elastomers, primarily the Sylodyn® HRB (Highly Resilient Bearing) HS series, designed to withstand extremely high static and dynamic loads.

2. What is the main function of these bearings?

   Their primary function is to provide reliable and efficient isolation of vibrations and shocks in buildings and structures, especially those caused by heavy external influences like rail or road traffic, or internal heavy machinery.

3. What key properties make Getzner’s material ideal for high loads?

   The material (Sylodyn® HRB HS) is a closed-cell elastomer with pronounced spring characteristics, a high dynamic load capacity, and a low creep tendency, ensuring it maintains its performance under constant, high-pressure use for decades.

4. How do these bearings achieve high load transfer in a small space?

   The special formulation of the Sylodyn® HRB HS series allows it to transfer concentrated loads very efficiently, providing the required degree of elasticity even in the smallest space.

5. Are these bearings used for structural support or just vibration isolation?

   They perform both functions. They enable the targeted transfer of concentrated loads within the load-bearing structure while simultaneously providing effective vibration isolation.

6. What is the maximum static load capacity of the high-load series?

   The top-tier Sylodyn® HRB HS range can withstand a high load transfer up to 12 N/mm²

7. What is the typical natural frequency achieved with these bearings?

   When used in building base isolation, these bearings are engineered to achieve a target tuning frequency generally between 8 Hz and 12 Hz for optimum vibration protection.

8. How does the closed-cell structure of Sylodyn® HRB HS benefit its use?

   Its closed-cell structure is critical because it means the material does not absorb water, making it highly suitable for applications involving foundation bedding and environments with high groundwater levels.

9. Where are High Load Elastomeric Bearings most frequently applied?

   They are essential for isolating vibration in: high-rise building base isolation, pile foundations, column heads, steel structures, and under heavy machinery (e.g., crane installations, heavy industrial equipment).

10. Are they suitable for railway track applications?

    Yes, Sylodyn® is extensively used in the railway sector, including for mass-spring systems, baseplate pads, and continuous rail bearings, to protect both the track components and adjacent properties.

11. Do these bearings come in different installation configurations?

    Yes, they are available as point bearings (for concentrated loads under columns), strip bearings (for load-bearing walls), or special customized bearings for pile foundations.

12. How are they used in pile foundations?

    They are used as elastic decoupling elements at the pile heads, often supplemented with filler material, to ensure the vibration from the ground is isolated before it enters the building structure.

13. Are they suitable for use under steel structures?

    Yes, their high load capacity and compact design make them ideal for the elastic bearing of steel structures where high loads act on very small support areas.

14. Do they have building inspectorate approvals?

    Yes, Getzner’s certified elastic bearings made of Sylomer® and Sylodyn® have been approved by building inspectorates, allowing for secure static proof procedures.

15. What is the expected long-term performance?

    The materials have a proven long-term behavior and are guaranteed to maintain their elastic and isolation properties for several decades (often over 50 years) with a very low creep rate.

16. Are they resistant to construction chemicals?

    Yes, Sylodyn® and Sylomer® have good resistance properties against diluted alkaline, acids, oils, and grease commonly encountered in construction.

17. What does the “HRB HS” designation signify?

    HRB stands for Highly Resilient Bearing, and HS stands for High Stress/High Strength, denoting the product’s classification for supporting extremely high vertical loads.

18. Is technical consulting necessary for designing a system with these bearings?

    Absolutely. Due to the high loads and complex dynamic calculations required to achieve the optimal tuning frequency, specialist engineering and acoustic consultation from Gitco are essential for proper system design.
