Highway bridge rubber bearing basin installation specifications are as follows: rubber bearing basin can apply to the design of the bridge, of course, the first consideration is the level which allows the corner and can withstand the thrust can meet the requirements. Generally, GPZ pot rubber bearing holder of each series can meet these two requirements. If the corners and horizontal thrust outside the allowable range, we need to change the bearing design. Corner King, can be ball bearings. Choose highway bridge rubber bearing basin the size of the bearing capacity, should be calculated according to the bridge dead load, live load settings on the sum of the reaction forces and the number of piers support. Suitable bearings generally: the maximum reaction force does not exceed 5% of the allowable bearing capacity of the holder, the minimum allowable bearing reaction force of not less than 80%. Specified minimum reaction force designed to ensure a good slip bearing performance, because the pressure is inversely proportional to the friction coefficient and the pot bearings, if less than a predetermined value, the friction coefficient will increase. When the optional seat, generally do not have too much to worry about bearing safety margin, such as a bearing calculated maximum reaction force of 4100, the minimum reaction force of 3,700, it is the choice of the bearing capacity of 4000 seat, this is because reaction force range allows support 4000 bearing 3200 - 4200, and choose not to consider increasing the carrying capacity of 5000 seat seat from a safer perspective. The lowest since 5000 bearing the appropriate carrying capacity is 4000, but 3700 has been minimal reaction forces less than this value, it is not appropriate to use. While we require maximum reaction force does not exceed allowable bearing capacity of 5%, but the actual seat safety factor of 5 or more in general. Here by the Hengshui Xu Rui professional and technical personnel to provide you with professional rubber bearing basin installation steps: 1, the proposed pier, table top surface is provided support cushion stone. 2, pot bearings should be installed before unpacking a comprehensive inspection and cleaning. Remove oil, especially relative sliding surface of stainless steel and filled with plates carefully cleaned with alcohol, other bearing each member should be cleaned, painted anti-rust oil can not be inside the holder. 3, the carrier must meet the design in addition to elevation requirements to ensure performance bearing shall ensure horizontal plane in three directions. 4, on a support, at each member must be in the vertical and horizontal, or at different temperatures due to the temperature and design the installation, bearing longitudinal distance between the upper and lower parts offset must be equal to the calculated value. 5, bearing centerline should coincide with the centerline of the main beam or parallel. 6, continuous bridge implementation system conversion, insulation measures must be taken between the seat and the grout block.
