TICO CV-CA High Stress Bearings
As building land in modern cities is at a premium, it is common practice to build on sites near or above main line and underground rail systems.
In addition, construction is becoming more closely allied to other major transport networks. These trends in construction demographics result in large amounts of ground borne noise and vibration which is transmitted directly into buildings through their, often deep, foundations. Such vibrations are a nuisance, particularly in parts of buildings where quiet is of paramount importance.
To achieve a major reduction in structural noise transmission it is necessary to separate one structure from another, or to isolate a complete structure itself from its foundation, depending on the source of vibration and amount of reduction required.
TICO CV/CA bearings have been developed for high load applications and have a maximum recommended working stress of 7000 kN/m2. TICO CV/CA bearings are typically used for isolating medium to large structures from ground borne vibration although they can also be successfully employed on other application, e.g. isolation of internal structures or high stress seating's in bridge bearing applications.
TICO CV/CA Structural Bearings can be used in a number of different configurations from modular pad arrangements on pile caps to continuous strip footings. In suitable configurations, isolation systems based around TICO CV/CA Structural Bearings can achieve natural frequencies of 8 -10 Hz.
TICO CV/CA bearings are dimensionally stable under widely varying atmospheric conditions and should provide
acceptable vibration attenuation properties for 50 years or more - the high quality constituents used in manufacture will render them durable and age resistant over many decades with a total bearing life expectancy well in excess of the normal working life of the building.
TICO CV/CA bearings have been designed and tested to meet and exceed the requirements of BS6177:1982 ‘Guide to selection and use of elastomeric bearings for vibration isolation of buildings’.
Typical CV-CA Bearing construction
TICO CV/CA is a high stress material composed of vulcanized laminates of the highest quality neoprene elastomer, modified by the inclusion of cellular cork, and reinforcing layers of high tensile fabric. The bearing surfaces are of a special formulation created to accept slight irregularities in bearing surfaces and to facilitate bonding on site using adhesives.
