General information | Product description ESZ Type 200 Composite | for static component storage Load-bearing capacity up to 37 N/mm? (depending on format) Materials: Vulcanisate based on CR rubber/steel $235 JR Maintenance-free and very durable Very good mechanical-physical characteristics ESZ Type 200 Composite is a steel-reinforced structural bearing with compact elastomer combined with reinforcement layers made larger than the elastomer layers all round. is intended for the static support of components, particular for large bearing heights. It is used in accordance with the provisions of the...

General information | Product description ESZ Type 200 Composite | for static component storage Temperature range The temperature application range is between -25 °C and +50 °C. The bearings may be exposed to temperatures of up to +70 °C for short, recurring periods of less than 8 hours. Delivery form As blanks for all standard reinforced and prestressed precast concrete construction elastomer base surfaces with drill holes. Total bearing height t = 15 / 25*/30/35/40/45/50/55/60 and 65 mm. (*not regulated in the approval) Boreholes Up to four boreholes are permitted per bearing, whereby the surface...

Planning tools | Load capacity and rotation ESZ Type 200 Composite | with national technical approval Calculation of the load-bearing capacity and consideration of the angle of rotation incl. surcharges The load-bearing capacity of the ESZ Type 200 Composite is limited by the manufacturerto 37 N/mm, the design function in Table 1 of the approval indicates significantly higher load-bearing capacities depending on the form factor. If the specific support situation is known and in direct consultation with ESZ, higher pressures may also be possible. The vertical load on an elastomeric bearing leads...

Planning tools | Rotation - rotation surcharge ESZ Type 200 Composite | with general building authority approval reduction in load-bearing capacity. Deviations from the plane parallelism and unevenness of the contact surfaces of the adjacent Geometric imperfections and deviations from the plane parallelism of the contact surfaces must be recognised with at least 0.01 rad [= 10 %e] and added to the calculated value of the bearing torsion. If contact surfaces must be taken into account with 625/a [%o] and calculated in the Same way as planned rotations. Bearing side a is always the shorter bearing...

Planning tools | Transverse tensile forces ESZ Type 200 Composite | with general building authority approval Information on transverse tensile forces in the bearing joint The elastomeric part of the bearing ESZ type 200 Composite is practically incompressible. As a result, the bearing expands transversely under compressive load at constant volume. transverse expansion by the neighbouring components - depending on the surface properties of the component. Roughness and surface friction are decisive influencing factors here. If the adjacent surfaces now counteract the lateral expansion of the elastomer...
