[Grid] rubber bearings used to calculate a foundation and basic aspects of multi-storey housing construction 1.1 no detailed geological survey report, based solely on the construction unit oral or general reference to the basic design information on nearby buildings for construction design plans. Foundation and foundation design to achieve reasonable grid slide bearing maintenance and installation, safe application, the designer must be based on geological survey data, unified study many factors underlying type and superstructure design Fang Ning, this endurance alone comprehensive data is incomplete, and it is unsafe, but not blindly endurance made smaller allowable value is considered as no one lost. [Grid] factory direct 1.2 rubber bearing soil replacement cushion using soft ground treatment, not-for-soil cushion design, just by experience disposal. Sometimes designers recognize hazards weak foundation deficiencies, simply by virtue of experience in the use of sand cushion to strengthen what capacity, no cushion width and thickness calculation, is neither safe nor economical. 1.3 Civil column, base load beam and failure to regulate the reduction factor is multiplied. When designers to multi-grid civil rubber bearing technology class, in the calculation of beams, columns and base load current design specification fails to Ge reduction factor is calculated by multiplying the load value of its load, thus load values ??accurately. [Grid] cheap rubber bearings! [Grid] rubber bearings PTFE slide bearing size and thickness gauge bridge in the calculation only PTFE slide bearing friction requests, did not directly explain how to determine the grid rubber PTFE slide bearings [branch Block] plane the size and thickness of the rubber layer. Many times truss supports, designers will PTFE slide bearing plane size and thickness of the adjacent pier made of ordinary laminated rubber bearings and other thick or simply too large values, this is not a strict approach. [Grid] Installing rubber bearing T-beam, if the seat bottom width than the beam reinforcement should stand in between the bottom and the additional reinforcement beams larger than bearing thick steel reinforced concrete pad or make the transition layer, in order to avoid bearing partial pressure, and the formation of stress concentration. Thick steel reinforced concrete pad or use a mortar and beams reinforced epoxy bonding adhesive bottom. After falling beams, seat top and beams to keep it level under normal circumstances. Prestressed simply supported beam, its top surface tilting seat later; non-prestressed beams its top surface can seat slightly forward, but the tilt angle should not exceed 5 "[grid] by adjusting the rubber bearings installed at the After the rubber bearing installation, if found the following circumstances, should adjust: A, individual seat dashed uneven force B, there is a greater initial bearing shear deformation C, [grid] partial rubber bearings severe pressure, partial pressure, abnormal bulging side, and local adjustment methods generally available fall jacking beam end, the upper and lower surfaces of the bearing shop coat of cement mortar (or epoxy mortar). off the beam again, in gravity the role of the upper and lower bearing surfaces parallel to each other and the same beam at the end, all of the top surface of tight pier; while bearing a dye ends in the same plane, the vertical beam tilt should be controlled seismic grid bearing installation and construction, When the seat is not to have a significant initial shear deformation is better. [grid] Rubber Bearing Installation Notes 2.4.1, bearing short side of the rectangle should be placed parallel to the direction along the bridge, in order to facilitate the beam end rotation. For a long When the edge is parallel to the direction along the bridge, to be checking through the corner. 2.4.2, isotropic circular bearing installation without considering directionality, simply mount the center position of the center coincides with the design can be. To prevent Under the centrifugal beam lateral movement, can be installed transversely stopper. grid bearing design parameters, grid bearing, rubber-Run-Run Company is provided by Hengshui Rubber Co., Ltd.
