[Slide] steel ball bearing hinge design principles of stability [slide] steel ball bearing hinge arrangement as well as the stability of the whole system must be considered an integral part of the current request is in accordance with the majority of flat steel system to design, such as truss and frameworks. To ensure that these structures do not appear flat plane instability, the overall layout of the structure need to be resolved, such as increasing the necessary support member and so on. Requirements flat planar structural members need stability calculation is consistent with the structural arrangement. KQGZ Seismic Isolation Spherical Bearings [slide] KQGZ seismic ball bearing hinge is spherical bearing Guangrun Hengshui Rubber Products Co., Ltd. specializes in producing steel ball bearings earthquake. The special structure bearing tensile, shear, and can reach the intensity of anti-seismic capacity of 9 degrees. KQGZ seismic spherical bearing main technical performance 1) bearing friction coefficient is 0.03. 2) the level of shear bearing vertical bearing capacity of greater than 20%. 3) bearing anti-pullout force of 10% vertical bearing capacity. 4) bearing vertical bearing capacity for 1000--60000kn, divided into 25 series specifications. 5) bearing adaptation temperature range -40- + 70 degrees. 6) The maximum allowable angle of seat 0.03rad. The maximum allowable amount of displacement 7) bearing positive and negative 50mm KQGZ main characteristics of seismic ball bearing structure boils down to: [] KQGZ sliding ball joint bearing steel ball bearings to seismic universal rotation, universal bearing, well to meet the upper structure of the various loads (such as dead load, live load, wind, seismic forces, etc.) transfer reaction force generated by the rotation movement requirements. [Slide] steel ball bearing hinge design stability Experiences 1) more than the current steel design computer software for structural steel by means of force calculation, strength and overall stability in the plane of the structure and components of the calculation can be done automatically rely on , plane strength and stability of the structure and components of the calculation, the designer needs to do another analysis, calculation and design. Good this time can be decomposed into the entire structure by a plurality of different elevations are arranged in the ball bearing structure of the seismic performance of the one-way system, at different load levels, the strength and stability of the structural system calculations. 2) flexural plate steel components locally stable in two ways: First, as the carrying capacity of buckling limit state bidirectional seismic ball bearings offer professional national standard, and by limiting the thickness ratio of the plate, so it is not a whole component before buckling failure; the second is to allow the panel members before the overall buckling failure, and use its carrying capacity after buckling strength member is determined by the effective cross-section after local buckling. [Slide] ball bearing hinge pipe section for compression members seismic reliable two-way ball bearing quality, should control the outside diameter and wall thickness ratio of seismic ball bearings, stiffeners press "Steel Design Code" (GB50017-2003 ) Section 5.4 provides the setting. [Slide] PQXZ series ball bearing hinge basin seismic ball bearing installation of conservation rules 1. This series bearings, the bridge girder and pier bearing parts of the concrete strength of not less than C40, designed to special circumstances unit agreement. 2. Supports and pier and beam connections using embedded bolts, if necessary, may also be embedded steel welded connections, but when welding, to prevent bearing steel body temperature is too high, so as not to burn the grease and tetrafluoroethylene Ethylene board. 3. Supports mounting height should meet the design requirements, so bearing formation; bearing bearing surface height may not play in the four corners of the earthquake 2mm ball bearings | reliable bi-directional seismic quality ball bearings | Guangrun Guangrun by Hengshui Rubber limited.
