Detailed Product Description: | Our company specializes in the production of seismic pot bearings, sliding bearings, sliding hinge bearing, universal activity hinge bearings, spherical rubber bearings, rubber spherical steel bearings, universal joints slide bearing, steel corridor limit bit support. Customers are welcome to buy. Tel: 15075853136 Cui Contact QQ: 1162984374 seismic pot bearings include fixed bearing and one-way bearing activities of two types, and with supporting the use of well-way bearing activities. Supports requirements into specifications according JT391-1999 31. Supports vertical design capacity, bearing angle, bearing friction coefficient and displacement according to the standard requirements of the design. Fixed bearing only one way in each direction and the direction of the movable bearing non-slip horizontal force bearing design bearing capacity of the original 10% to 20% improvement. Because GPZ (KZ) Series seismic rubber bearing basin design with a fixed bearing and one-way bearing activities, so if the two types of bearings used in conjunction with seismic bearings than setting fixed only on the bridge piers to improve the entire bridge structure seismic capacity is the best. Pot bearing component seismic structure (GD fixed seismic type), mainly by the attendance sheet, energy dissipation plate, seals, rubber sheet, bottom pots and damping apron and other components. GPZ (KZ) DX (one-way pot bearing seismic activity) as well as the intermediate plate, PTFE slide, stainless steel slide and lateral slip devices. The main principle is that when the damping level is greater than 20% bracket bearing design vertical bearing capacity, energy dissipation plate starts slipping, played the first isolation effect, and then play the second damping ring road damping effect, support Block play a role in the earthquake. When the earthquake shock exceeds a certain limit, the rigidity of the series of the third seismic shock effects played. Seismic bearing capacity of a pot bearings, bearing vertical design bearing capacity: This series bearing design bearing capacity of sub-31, that 0.8,1,1.25,1.5,2,2.5,3,3.5,4,5 , 6,7,8,9,10,12.5,15,17.5,20,22.5,25,27.5,30,32.5,35,37.5,40,45,50,55,60MN. Bearing capacity of the bearing design allows overloading 10%. From 0.8 ~ 60MN. In the vertical design load bearing bearing compressive deformation amount not greater than the total height of 2%, the deformation of the basin ring diameter is not greater than the diameter pots collar Zan 0.5 ‰. Fixed bearing seat into GD, DX-way bearing activities, SX-way bearing activities, displacement of the movable carriage into third gear; amount of displacement may require special concrete design. 2, the horizontal bearing capacity: fixed support activities in all directions and one-way bearing non-slip direction of horizontal bearing can withstand 20% bearing design bearing capacity. Seismic pot bearings for seismic earthquake country principle rubber bearing basin countries for acceptance and installation of seismic rubber bearing basin acceptance and installation is very important, so the construction unit when installing seismic rubber bearing basin, to The support pad stone installation settings in order to ensure the construction quality seismic bearings, as well as adjustments to observe and replacement bearings convenience, regardless of method is the use of cast or precast girder beam construction method, no matter what type of installation rubber bearing basin , set up branches at the top of the pier pad stone are required, which has two main requirements: 1, on the seismic bearing flat stone bearing pad size should be able to withstand the load of the upper structure is appropriate, the general length and width than steel pot bearings under large 250mm or more. Should be greater than the height of the stone pad 65mm, in order to ensure that the top surface of the piers have enough space height, for accommodating a jack, used for bearing exchange. Mat made of stone around the slope to prevent water 2, there must be sturdy steel mesh installed in the bearing pad stone, vertical steel piers should be connected when the steel and solid. Pouring cement pad stone with the label of not less than No. C40, the top surface of the concrete pad stone horizontal ruler calibrated in advance, and strive to smooth and clean. 3, for the production of seismic rubber bearing basin type acceptance is based People's Republic of China Ministry of Transportation industry standard requirements for acceptance. Supports various components such as steel, rubber, PTFE plate, stainless steel slide, etc. The material must meet the standards. Stand between quality and appearance parts tolerances shall comply with the standards and requirements of design drawings, with particular attention polytetrafluoroethylene plate and intermediate plate groove seal between the ring and the rubber plate pots and steel pots tolerances, also deal with the appearance of stainless steel and Teflon quality skateboard skateboarding checked, and according to the manufacturer packing list for accessories such as anchor bolts, pillar, washers, etc. for acceptance. 4, for bearing the overall mechanical performance test according to standard methods. Test items include pots bearing vertical compression ring and radial deformation. Standard requirements at the design load bearing vertical compressive deformation shall not be greater than 2% of the total stand high on pot ring diameter no larger than 0.5 ‰ to deform the outer diameter of the ring basin, bearing residual deformation shall not exceed the total amount of deformation of 5 %. Instead of testing the entity bearing friction coefficient chosen bearing carrying capacity of not more than 2MN activities bearing or specimen. Seismic pot bearings, sliding bearings, sliding hinge bearings, universal joints bearing activities, spherical rubber bearings, rubber spherical steel bearings, universal joints slide bearing, steel bearing corridor limit |
