Description
Technical field
The utility model relates to a kind of shock-absorption technical field, particularly relates to a kind of steel work shock isolating pedestal.
Background technology
Shock isolating pedestal can directly select corresponding bearing model specification according to the earthquake motion peak acceleration of the bridge location such as (house building), and should consider to select the horizontal rigidity of bearing and the maximum shear strain inspection no instructions for use met under the effect of sympathetic earthquakes power at last.According to span and range of temperature, and should consider that the factors such as construction deviation select the bearing of corresponding displacement.Should meet the locus requirement of the structure of actual bridge construction etc., sleeve and anchor pole should be avoided conflicting mutually with structure stress reinforcing bar.Owing to making production thing according to the difference adapting to rotational angle theta, rubber design shear modulus G value size, distinguish respectively, bridge construction engineer should carry out type selecting according to the actual conditions of every bridge block, with stressed and service condition of optimizing structure, ensures that product plays its due effect.
Should examine when bearing is arranged and calculate the design displacement of bearing and whether meet the displacement demand that bridge causes because of the actings in conjunction such as brake force, concrete shrinkage and creep and temperature and seismic forces.Fixed bearing conventional sense bottom offset amount must not exceed susceptor design and normally use shearing strain, and earthquake state bottom offset amount must not exceed susceptor design earthquake and use shearing strain.Continuous beam simply connected length no more than 200m, across number no more than six across; If desired more than six across time, bearing arranges whether should examine the displacement of fixed bearing calculated near sliding-type bearing meets displacement demand, more according to circumstances sets up sliding-type bearing or carry out custom design.Rectangular fixed-type bearing should adopt bearing minor face and suitable bridge to being arranged in parallel, and when bridge lateral is size-constrained, the long edge of bearing can be adopted to indulge bridge to layout.Should notice during sliding-type bearing settlement that its glide direction is consistent with the main displacement direction of bridge.Current existing shock isolating pedestal shock insulation scope is less, and isolating affection is general, can not meet large-scale use.
