[Seismic] ball hinge support equipment selection and construction units should try to use a high-performance, low noise, less pollution equipment, construction and non-construction area locales separate standard facilities, the construction site using hot water boiler must use clean fuels urban (1000 meters away from the residential areas) disabled diesel pile shock, vibration pile driver, pile driver and diesel generators seismic rotation ball joint bearing, non-beat and drill pipe, high noise pollution control, comprehensive utilization of construction waste, shall adopt a plan angle lighting to avoid light pollution. Installation [seismic] ball joint bearing plate and anchor bolts, should then the next four weeks with steel bearing plate bearing adjustment module level and use the [earthquake] ball bearing hinge plate above the bottom surface of the pier (Taiwan) Top 20 -50mm, identify the holder longitudinal and transverse centerline position, to conform to the design requirements. When the bolt hole with epoxy mortar perfusion and bearing cushion between the bottom surface of the pot bearing is provided with a support cushion stone pier no shrinkage bedding mortar Taiwanese reserved bolt hole forms generally reserved Seismic ball bearing hinge displacement, there is also the collar holes for practice. Installation should be [the earthquake] ball bearing hinge Notes: 1. Install the front bearing activities carefully wipe with acetone or alcohol wash each relative sliding surface PTFE slide after wiping the reservoir tank is filled with grease poise lubricants, and pay attention to cleaning the grease; grease for oil filling ramp bridge note should pay attention to slip. 2. [seismic] ball joint mount top and bottom plates connected by welding or anchor bolts embedded steel beam on the bottom and the top surface of the pier; when welding corridor seismic ball joint bearing, should prevent burns concrete; When installing anchor bolts look, their exposed screws shall be not greater than the thickness of the nut; cast embedded steel beam bottom, should be based on the temperature of pouring time, prestressed tension, concrete creep and shrinkage effects on the beam length, set with respect to the pre-offset value design support center. [Seismic] ball hinge support action under the bearing capacity of vertical design, bearing compression is not more than 2% of the total height of the holder, the ring diameter steel pots and pots of deformation is not more than 0.05% ring diameter. [Seismic] ball joints bearing horizontal bearing fixed bearing and one-way movable bearing non-displacement direction of the horizontal bearing capacity of bearing vertical bearing capacity of not less than 10%. 3) bearing vertical angle of rotation angle of not less than 0.02 rad. Seismic work properly when the ball joint bearing steel bearings, bearing vertical rotation angle of not more than 0.02 rad. [Seismic] ball joints bearing friction coefficient plus 5201 grease lubricated, room temperature, type of activity bearing friction coefficient of less than 0.03. Plus 5201 grease lubricated, cold-type movable bearing friction coefficient of less than 0.06. 5) the displacement of two-way and one-way bearing activities bearing activities along the bridge to the amount of displacement is divided into five: ± 50 mm, ± 100 mm, ± 150 mm, ± 200 mm, ± 200 mm; transverse to the two-way bearing activities displacement of ± 50 mm. When there are special needs, according to the actual need to adjust the amount of displacement, the displacement of poor adjustment of ± 50 mm. [Seismic] ball joints bearing bridge rubber bearing type selection principle of selection, should be combined with a bridge span, load rating, bridge bearings depending on the working principle of vertical and horizontal to the slope, in the form of a bridge structure, climate and seismic rating, bearing form factors such as a reasonable choice. Seismic Corridor ball hinge support, seismic ball hinge support, provided by the company Guangrun-Engineering Rubber Co., Ltd. Hengshui. Hengshui-Engineering Rubber Co., Ltd.
