Structural Protection Systems Technical information, dimensions and weights MAURER SOHNE

The construction principle of a pot bearing corresponds to a xed bearing and thus allows rotations around any horizontal axis (point tilting) by shear deformation of an elastomer pad included in a steel pot. The used elastomer keeps its volume constant under allround compressions and thus is incompressible (no sinking under load).

Fixed pot bearing TF Dimensions and weights acc. to German approval Stura di Demonte viaduct, Italy The table is based on a permissible compression of σ exz. = 26 N/mm2. We supposed normal conditions min. V = 0.5 · max. V and a horizontal force HRes = 0.1 · max. V. Angular rotation tan ϕ = ± 0.01. Dimensions and weights for deviating permissible concrete pressures and unusual load conditions will be calculated on request. Depending on the area of application and country requirements MAURER pot bearings can be supplied in accordance with various standards, e.g. EN 1337, DIN 4141, BS5400, AASHTO,...

Generally mobile pot bearing TGa Dimensions and weights acc. to German approval Twistetalbrücke, BAB A44 Kassel — Dortmund, Germany The pot bearing’s dimensions are determined by the permissible compressions in the elastomer pad, larger permissible concrete compressions do not result in smaller bearing dimensions, therefore the tables are only based on the value σ exz. = 26 N/mm2. We supposed normal conditions min. V = 0.5 · max. V. An angular rotation tan ϕ = ± 0.01 as well as a lateral displacement ey acc. to DIN 4141 of at least ± 20 mm have been assumed. Dimensions and weights for deviating...

Unilaterally mobile pot bearing TGe - 26 N/mm2 Dimensions and weights acc. to German approval Vasco da Gama Bridge, Portugal The table is based on a permissible pressure of σ exz. = 26 N/mm2. We supposed normal conditions min. V = 0.5 · max. V and a horizontal force in lateral direction of Hy = 0.1 · max. V. Angular rotation tan ϕ = ± 0.01. Dimensions and weights for deviating permissible concrete pressures and unusual load conditions will be calculated on request. Depending on the area of application and country requirements MAURER pot bearings can be supplied in accordance with various standards,...

TGV viaduct at Avignon, France building regulations approved quality supervised world-wide proved Economical due to its simpleconstruction method. Reliable by use of proven materials, non-constrained displacement and use of a wear-resistant pot seal. As basic materials steel and elastomer (carbon/PTFE) in bridge bearing quality (PTFE) are used. Small restoring moments in case of the usual superstructural deformations.
