If the design calculations fully consider the impact of all constraints, support may also be considered tangential arrangement. In this way the structural support, under the temperature and contraction, bearing displacement tends to polar coordinate direction. Tangential way activities will be bound (bound activity), bearing chant tangentially oriented and able to withstand the horizontal forces, the sum of these binding, depending on the size and structure of the stiffness curve radius. The binding may be quite large seismic grid KQGZ type steel ball bearings, and other forces must (braking force winds and the inertia force) by the vector overlay. In short, usually due to the sliding part of the activities and the rotating part of the bearing are separated, bearing in displacement, but also can be applied to each rotation, as long as the bearing design takes full account of the displacement of the binding of the bearing beam The role of the two seat arrangement system are available. Piers is a relatively newly plate pier, bridge set up a central fixed bearing, fixed bearing support on the remaining side pier, located one-way bearing activities tangentially, on the other side set up multi-directional sliding bearings, abutments in fixed bearing side, set up a one-way activity laminated rubber bearing tangentially, on the other side to set up multi-laminated rubber bearing activities. Piers is a relatively newly pier plate, set a fixed central bridge abutment, piers and abutments remaining in the fixed bearing side LKQZ steel ball bearing type seismic grid, located along the tangential direction unidirectional bearing activities, The rest are set to more bearing activities. Are used for full-bridge is GKGZ laminated rubber bearing steel ball bearing type seismic grid, polar direction arrangement: a relatively rigid piers for seismic pier plate steel ball bearings, bridge in a fixed set of laminated rubber bearings Another side to set up multi-laminated rubber bearing activities, abutments are located along a one-way activity laminated rubber bearing polar direction. Deck hinge narrow curved continuous girder bridge (eg ramp bridge) can also be arranged on the middle pier located monopile, try to set the double seat at the end of the beam to the Union, in order to withstand the torque curve of the beam to the stand deviates outward curve, torque adjustable beam cross section. Lateral plate by five pinch bolts M24 × 2 seismic steel ball bearings. In the middle of the bolt when the test patch on the intermediate measured stress. According to the analysis of the pressure on the theoretical value of the bolts around the rubber side force H of 2.14 times. Measured bolt tension with the calculated values ??are also very similar. Seismic steel ball bearing steel hardness lateral force stress, not the vertical displacement and compression of the rubber itself influence is negligible. Simply select the appropriate size of the bezel thickness bolts, you can ensure the seismic stress ball bearing steel bearing and allows lateral steel bezel yield stress under appropriate conditions, the loss of carrying capacity to meet consumer earthquake energy purposes. You can replace the seismic steel ball bearings and bearing lateral steel bezel for repair after the earthquake. Seismic steel ball bearing construction details due to seismic steel ball bearings are exposed to seismic horizontal force in 0.2P above, then contact stress acting on the bearing plate and the lower middle seat between steel pots significantly greater than the general steel support Block (design level force 0.1P), check this purpose on the one hand by Hertz formula calculation, steel flange contact stress in the middle, on the other hand to improve the basin under the seat material strength steel and bearing steel in the lower basin surface, surface hardening treatment, in order to improve the surface hardness, the surface of the steel sheet to prevent bad eating flange mixing bowl.
