TICO Structural Bearings - CV/M

TICO CV/M - Medium Stress Bearing TICO CV/M is a medium load structural bearing material, engineered to reduce the transmission of ground borne and structure borne noise and vibration, for example vibrations transmitted into and through buildings from nearby public transport systems or road networks. TICO CV/M has a maximum recommended working stress of 1400 kN/m2 making it suitable for a wide variety of applications. To achieve a major reduction in structural noise transmission it is necessary to separate one structure from another, or to isolate the complete structure itself from its...

Physical Properties TICO CV/M is formulated from the highest quality neoprene which has been modified by the inclusion of cellular cork particles. Thicker pads may be reinforced with a central layer, or layers, of high tensile fabric. Maximum Recommended Working Stress Working Stress Range In excess of 3 times the maximum recommended working stress (in accordance with BS6177) Hardness (IRHD) Density (Typical) Temperature Range -30 to +70°C Performance of bearing may be impaired at extremes of durable temperature range. Typical Damping Ratio Thermal Conductivity

Design Considerations Because of the wide range of applications for which TICO CV/M is suitable, and the variation of material properties under different operating conditions it is difficult to provide a simple design guide. Key parameters in the specification of TICO CV/M bearing are: TICO CV/M bearings can be employed in thicknesses in multiples of 25 mm to provide the required natural frequency for a specific project. When a low natural frequency dictates that a very thick bearing is required, it may be necessary to provide some form of horizontal restraint, e.g. dowels or side restraint...

Installation Installation of TICO CV/M structural bearings will vary from application to application and also depend on the design and arrangement of the bearings. For plain bearings, pads or strips should be securely fixed in position with Tiflex Marine Epoxy Adhesive. The instructions for use of this adhesive should be followed carefully. Pre-cast units can be placed directly on the top of the bearing without any further bonding. If the bearing surface is sloping or very irregular, a small level plinth can sometimes be cast to support the bearing as in the following diagram. Good surface...

Supply Details TICO CV/M is manufactured in sheet form up to a maximum sheet size of 1200 x 1000 mm. However, it is more common and advisable to employ this material in modular or strip form for the best performance. Typically supplied bearing sizes and load bearing capacities are given in the following table. Length Width (mm) (mm) Maximum Recommended Load (kN) Tiflex recognises that in civil applications bearings often have to custom sized to meet the project requirements and thus we are happy to supply custom sizes up to the maximum sheet size available. Standard thicknesses of TICO CV/M...
