CV/LF and CV/CF TICO Structural Bearings

Isolation of vibrations from one part of a building to another is as equally important as isolating the whole building itself. Indeed, in many cases, isolating key parts of the structure internally is often more practical, convenient and economical than isolating the whole building at foundation level. TICO low stress, low frequency bearings - TICO CV/LF and TICO CV/CF - have been designed specifically for total or partial support of all types of internal structures such as anechoic chambers, recording studios, floating floors, theatre stages and any other structures where quiet is of...

TICO CV/LF- Low Frequency Bearings TICO CV/LF bearings comprise a specially moulded central layer of highest quality neoprene in a fluted configuration sandwiched between two flat face plies of a cork loaded neoprene composite material that facilitates bonding of the bearing on-site with adhesive. TICO CV/LF/B There are two grades of TICO CV/LF available: TICO CV/LF/B For stresses up to 70 kN/m2 TICO CV/LF/N Both materials are supplied as standard in a single layer configuration which can be doubled up to provide enhanced performance. With appropriate configurations isolation system natural...

TICO CV/LF- Low Frequency Bearings Bearing Stress vs Static Deflection Stress/Deflection Characteristics TICO CV/LF/B 6 These graphs have been prepared from the results of extensive testing over many years. Where appropriate, data has been presented in the form of a shadow graph to illustrate the effect of shape factor on performance of the pads. All data is presented for guidance only.

TICO CV/CF bearings are natural rubber based mirco-cellular materials with high tensile geotextile upper and lower surfaces which protect the bearing surface, facilitate bonding and accommodate small surface irregularities. TICO CV/CF/B TICO CV/CF/N Maximum Recommended Working Stress 100 kN/m2 Working Stress Range 25-100 kN/m2 In excess of 3 times the maximum recommended working stress (in accordance with BS6177) Weight Density (Typical) TICO CV/CF bearings, unlike TICO CV/LF, are manufactured in sheet form and can be cut to virtually any size within the maximum sheet dimensions of 1000...

TICO CV/LF and TICO CV/CF can be used in plied up layers to give even better performance. However we strongly suggest contacting our Technical Department when considering such options as thicker bearings can lead to instability within a structure which may need to be addressed with some form of reinforcement or restraint. The incorporation of resilient structural bearings into a structure has to be considered at an early design stage to enable a safe, effective and economical system to be engineered. Detailing such systems late in the construction process can cause major complications and...

TICO CV/LF and TICO CV/CF bearings are available in a range of standard sizes as follows: TICO CV/LF/B TICO CV/LF/N 25 mm (single layer) 32 mm (single layer) Tiflex recognises that in civil applications bearings often have to be custom sizes to meet the project requirements and thus we are happy to supply custom sizes up to the maximum sheet size available. TICO CV/LF bearings can be supplied in single units up to a maximum of 600 x 150 mm. Each grade of CV/LF is also available in multiples of standard thicknesses, e.g. a double layer CV/LF/B pad is 50 mm thick and similarly a double layer...
