GPZ pot rubber bearing, the rubber used in the absence of bond issues, which EPDM is an ideal low-temperature rubber. 1978 Red River Academy of Railway Sciences railway cable-stayed bridge with a rubber bearing basin 9MN were real bridge bearing friction coefficient of determination. Determination is in front of the beam segment close together and set up the cracks in the beam jack, jack pressure by measuring the level of force used sliding bearings, bearing friction coefficient measured 0.019, the results of this trial with the bearing value is close. Altitude slip assembly method 2 to March 1991 Tangshan New stadium used roof truss construction. New stadium for 50 × 60m orthogonal plane being put all-welded steel plate grid, grid height ranging from 3.5 ~ 4.46m respectively, grid capitals elevation of 12.25m, truss total weight of about 250t, grid structure To find the slope, four fell into the roof cornice four weeks 2.5m. In the north of the stands at the stadium, and the erection of high-altitude assembly units, will be arranged in a stadium outside 20t crawler (north), is responsible for high-altitude grid assembly. Slip, using pulleys, chain hoists for use 5t slip traction. Architecture GPZ pot rubber bearing high-rise building with the development of production and social progress of science and technology and evolving. With the increase in the level of economic growth and high-rise buildings, seismic analysis and design has become increasingly important. In particular, China is in an earthquake-prone area, high-rise buildings more earthquake-proof engineering design is an urgent task facing the high-rise building structure earthquake is still an important issue to consider building safety. [Pot] pot bearing rubber bearing installation method A pre-installation check rubber bearing basin is made after the entire assembly factory shipment. Should be fully checked before installing large displacements wx cheap pot rubber bearing, see whether the missing parts, damaged. B installation site requirements for installation of the beam bottom bearing parts of the concrete should be smooth and clean, it is best to use a local steel plate. Pier top surface mount installation site, the application of high-grade epoxy mortar made of sand or stone bearing pad large displacement sx big rush to buy rubber bearing basin, the height should be considered bearing pad stone conservation, convenience checks, and should consider the possibility of replacing the roof beams when support. 【】 Rubber bearing basin installation (1) Installation cast beams, typically bearing large displacement dx overall lifting rubber bearing basin promotions, fixed position in the design, with the upper and lower links in place after construction. Precast beams, on the bearing, lower seat board, only one first link, usually the first link in the bearing plate girders attendance, then according to their position on the pier at the end of pots to determine the position of the last to be fixed . Thrusting Continuous Beam pot rubber bearing, should first Xiazuo plate fixed on the pier, but also set up a temporary seat on the pier, when the main beam push completed, and correct the position, remove the temporary supports, Let the beam falls on the stand. (2)] [rubber bearing basin along the centerline of the bridge to be coincident or parallel to the centerline of the main beam. For the movable bearing centerline Xiazuo plate transverse direction shall be calculated according to the temperature of its staggered away, after staggered on board should be parallel to the center line of the lower seat. Bearing installation elevation should meet the design requirements, to ensure that the level seat plane in both directions, bearing bearing surface height is not greater than 2 mm corners only allowed activity for a seat in one direction, the upper and lower guide bearing plate block block must remain parallel, its crossing angle not greater than 5 ', otherwise it will affect the displacement performance. (3) [] after pot rubber bearing position determination, then its the same bridge, the lower link.
