ESZ type 150

Product catalog summary
Overview: This document provides technical specifications and guidelines for ESZ type 150 elastomeric bearings, used in static component bearing applications. It includes load-bearing capacities, design considerations, and installation instructions.
Specifications: ESZ type 150 bearings are designed for use between precast reinforced concrete elements and as in-situ concrete point or strip bearings. They have national technical approval Z-16.32-483 and can withstand compressive stress up to 21 N/mm², available in thicknesses of 10, 15, or 20 mm.
Design Considerations: The document highlights the interaction between compressive stress and rotation, which is not fully covered in the tables. Drilling holes in the bearing changes the shape factor, affecting design. The ESZ dimensioning tool is recommended for specific applications.
Load-Bearing Capacity: Tables provide maximum permissible load-bearing capacities with corresponding rotational capacities. The capacity is limited to 21 N/mm², though higher capacities are possible depending on the shape factor. Effects of compressive stress and rotation on neighboring components should be considered.
Installation Guidelines: Conditions for boreholes include up to four per bearing, with the area not exceeding 10% of the total bearing area. The distance between holes must be at least twice the diameter, with a maximum hole diameter of 50 mm.
Design Formulas: Formulas for calculating load-bearing capacity consider support torsion, with specific calculations for rectangular and round bearings.
Contact Information: For assistance, contact ESZ Wilfried Becker GmbH at Weilerhéfe 1, 41564 Kaarst, with phone and email details provided.
Specifications and Standards: The document discusses the interaction of load action and angular torsion, emphasizing mathematical analysis to verify load-bearing capacity. Deviations in plane parallelism and contact surface unevenness are treated as planned rotations.
Transverse Tensile Forces: The ESZ type 150 bearing is incompressible, leading to transverse expansion under compressive load. This expansion is restricted by neighboring components, causing shear stresses. The document compares old DIN 4141-Part 15 standards with DIBt approval for calculating transverse tensile forces.
Calculation Examples: Examples for calculating transverse tensile forces and load capacity under rotation are provided, with detailed formulas and assumptions.
Installation Instructions: Practical guidelines emphasize clean, debris-free bearing surfaces and proper alignment. Instructions are given for handling environmental influences and surface imperfections.
Key Recommendations:
  • Ensure mathematical verification of load-bearing capacity considering torsion and geometric imperfections.
  • Follow updated DIBt approval standards for calculating transverse tensile forces.
  • Maintain clean and properly aligned bearing surfaces during installation.
  • Avoid stacking storage units and ensure proper joint separation to prevent unintended fixed points.

Deformation behaviour | Compression characteristic and bulging behaviour ESZ type 150 | for static component bearing The following pages show pressure compression characteristic curves and the bulging behaviour for selected bearing formats in diagram form. The orientation diagrams make it possible to estimate the deflection as a function of the existing compressive stress. The characteristic curves were centric load application. The diagrams each show the evaluation at the third load on the bearing. In construction practice, the deflection may deviate from the values of the compressive compression...
