Highway bridge bearings in an important position on the bridge, the connection point of the lower structure, which directly affect the safety level of reliability and durability of the bridge structure, therefore, in addition to ensuring reasonable highway bridge bearing design selection and processing quality meet the technical standards outside The correct construction and installation of highway bridge bearing the key to the success of the application. Construction of the highway bridge bearings installed special requirements. In order to ensure the requirements of the construction quality of laminated rubber bearing. In order to ensure the quality of construction of the highway bridge bearings, as well as installation, adjustment, and replacement bearings for easy observation, no matter what method is still pouring on existing precast beams made of construction, no matter what type of laminated rubber bearing installation, usually in the top surface of the highway bridge pier support cushion stone setting is necessary ball bearing hinge, roads and bridges support cushion stone set in mortar pedestal steel spherical bearings, highway bridge bearing top surface of the lower structure is a catheter must be corrected handling, processing requirements are standard traits according to the traits suitable circumstances support cushion stone. Highway bridge bearing pad size flat stone bearing strength shall be calculated locally, the general direction of the length and width should be larger than the next one will stand above their corresponding size 50mm. Stone pad height shall be not less than 100mm, to ensure that the end of the pier from the top surface of the beam by enough space height. To place the jack in order to adjust or replace the use support. Highway bridge bearing equivalent stiffness constant equivalent, from LRB hysteresis characteristics equivalent linear model, calculate the total energy absorbed by the seat of elastic bearing the principle of work carried out according to the following formula performance, highway bridge bearing equivalent stiffness, shear stress depends on the money and the value of Q-type non-fixed value, he along with the increase of the deformation decreases bearing supports, its variation, our test Chang'an University The results are basically the same variation with foreign-related tests. Therefore spherical bearing hinges, the money value of the shear stress in the design of LRB, according to the deformation of bearing, is determined by the formula, the design of roads and bridges lead rubber bearings, we must first choose diameter pin set lead, to get the best energy damping effect. Because when the seat height is constant, the highway bridge bearings dissipate energy absorption capacity, with the lead pin diameter increases with the increase, due to increased lead pin diameter increases the yield strength of the highway bridge bearings, the corresponding increase Supports large area due to hysteresis curve, that is, when the lead pin diameter is small, multi-layered rubber bearing on the cash box constraints will be very full.
