GPZ pot rubber bearing, although natural rubber with high tensile strength, excellent flexibility and good low temperature resistance, aging resistance, but its performance is poor. Therefore there is a need to study both aging and resistance to low temperature rubber for use in rubber bearing basin in the low-temperature region. EPDM is a synthetic rubber development this year, has excellent resistance to aging and low temperature properties. EPDM resistance to ozone aging and weathering performance is much larger than the natural homesick and neoprene. Thickness GPZ pot rubber bearing the same cross-sectional dimensions of the wall in the seismic shear wall structures. Seismic wall surrounding the beam should be set (or dark beams) and end column consisting of the border end: end column section should be the same column with the same layer framework and shall meet the requirements of the frame column. Reinforcement requirements ① seismic strengthening parts of the bottom end wall columns and walls close to the hole seismic end leg stirrups should be required to post the encrypted area along the full height encryption stirrups. ② seismic vertical and lateral distribution of the wall reinforcement steel strings should not be less than 0.25%, and should double layout; reinforcement spacing should not exceed 600mm, diameter of not less than 6mm. Frame - core tube structure shall meet the following requirements: ① floor between the core barrel and frame cast slab system should be adopted. ② below 9 degrees when using a reinforcement layer, reinforcing layer girders or trusses should be the core barrel through Pier: Connecting girders or trusses and perimeter columns should adopt the framework articulated or semi-rigid connection ③ structure should be included in the overall analysis strengthened layer deformation. ④ fortification should not be used as a reinforcing layer 9 degrees. ⑤ on the construction program and connecting structure, should take measures to reduce the vertical temperature structure of the axial compressive deformation and the strengthening layer. [] Rubber bearing basin in order to increase the amount of displacement calculation smooth driving, and now a large bridge expansion joints are large spacing, which requires a large amount of displacement of the bearing. Each level has a large bearing activities, a small amount of two kinds of displacement. Therefore, in the design of rubber bearing basin, need to calculate the maximum amount of vertical displacement of the bridge bearing activities. Vertical displacement of the bearing to the bridge should include temperature changes, concrete creep, displacement and displacement caused by braking force caused by the shrinkage of concrete. Bearing transverse displacement can meet the requirements to the general, without checking. Rubber bearing basin] [construction] [rubber bearing basin preparatory work before installation pot rubber bearing parts should be checked before installation is complete. Application for movable bearing alcohol or acetone to clean the surface seismic activity relative DX pot rubber bearing good quality dry after 295 painted in the PTFE slide grease grooves. Bearing pad stone top and bottom of the beam bearing installation site must be clean and smooth. According highway bridge construction specifications, bearing corners height not greater than 2mm. [Pot] installation of cast rubber bearing girder should be the cradle and the floor under the temporary fixed relative position, lifting the overall seismic technology class GD pot rubber bearing, fixed in the design position. For lifting precast girder, it should be fixed on the bearing plate girders attendance, and then determine the end of pots on the pier location. Specializing in the production of continuous beam WX seismic rubber bearing basin has a temporary seat and should be fixed Xiazuo plate girder construction to be completed, and after adjustment for location, remove the temporary supports, so that the beam falls on the stand. If the Department of sulfur mortar temporary bearing rubber bearing basin, in the removal of temporary supports, insulation measures must be taken between the bearing and the temporary supports, to avoid damaging the PTFE slide. When the seat is installed, it must be coincident or along the bridge girder centerline parallel or tangential to the centerline.
