[Slide ball bearing hinge [slide] The main technical features of ball bearing hinge] GPZ (111) damping pot bearings retained the original pot bearings bearing capacity, flexible rotation, building height is low. Its basic structure is the addition of a rubber plate on its surface has a lower energy dissipation plate steel liner plate, and one-way activity in the middle of plates bearing or fixed bearing basin has a plug on the lower surface energy dissipation board, and in the mouth of the basin margin bearing steel notch features a dry-friction surface, at the level of seismic force dry friction surfaces can slide, earthquake energy consumption. In the usual dry friction surface does not slip, it does not produce damping rubber ring extrusion. [Slide] steel ball bearing hinge instability classification 1) a stable equilibrium problem bifurcation (branch point instability). Perfect straight bar and plate buckling buckling surface pressure during axial compression when both fall into this category. Stability 2) no equilibrium bifurcation (extreme point instability). [Slide] ball bearing hinge made from construction steel steel hinge bearing eccentric compression members, incapacity at the time of the plastic to a certain extent more stable steel hinge support to the activities of national standards, fall into this category. 3) Jump instability is a problem different from the above two types of stability, it is the loss of jumping to another stable equilibrium state after a stable equilibrium. [Slide ball bearing hinge] GPZ (111) damping pot bearings require installation sequence 1. Press the design requirements set aside bolt position. 2. styling template will bolt cast in stone pier pad bidirectional damping steel hinge bearing trustworthy, bolts and steel piers connection (Note: flatness, bearing centerline according to design requirements) 3 stone floor mat. 2mm epoxy mortar overlay on the stand in place and tighten the bolts. 4. After the upper beam in place, remove the positioning slab. [Slide] ball bearing hinge frame beam fabrication and installation. [Slide] ball bearing hinge executives and high-rise steel frame beam usually h, steel columns and beams frame suitable rigid connections inside the steel columns, beams of the upper and lower flange of the frame to set the transverse stiffeners. Frame beams produced at the factory, in order to ensure that the node domain steel columns and beams frame junction with good connection reliability and ductility storey guarantee the accuracy of the location, the framework should be set up where the cantilever beam, also known as short corbel . When the group is connected using high-strength bolts. For hole position accuracy requirements are very stringent. Currently, the general system of multi-axis CNC drilling and templates are two methods bore hole, the former high accuracy. The latter low precision, priority should be given to the former. If using a template system holes, in order to ensure the accuracy of the assembly of high-strength bolts hole mounting holes and site requirements, you should first ensure the accuracy of the template. If the hole deviation occurs locally, prohibited the use of gas cutting reamer seismic steel hinge bearing GB quality, but should be used reamer reaming. [Slide] ball bearing hinge height adjustable pot bearings currently include adjustable height and slope adjustable categories. According to Reference 8 introduced abroad there is a height-adjustable seat after installation by pressure injection of silicone rubber to adjust the seat height of the pot bearings. Grouting pipe design on the floor of the bearing, in the continuous girder bridge used for the adjustment of the stress generated by differential settlement of the foundation by grouting pressure injection of silicone rubber, the thickness of the inner pot bearings to increase the pressure of the rubber sheet , thereby adjusting the seat height. [Slide ball bearing hinge] There have been specially designed by the Ministry of Railways Institute of Science and height adjustable pot bearings, these bearings are provided with trapezoidal thread in the general pot bearing height adjuster, and through trapezoidal thread The height adjuster to achieve height adjustment bearing.
