Steel ball bearing slide hinge design problems and countermeasures sliding steel ball bearing hinge is a relatively new form of building structure, the recent rapid development, its advantage is particularly evident. From the characteristics of the steel structure, the system analyzes the steel structure design, selection, cross-sectional design, design support, node design and other issues, some of the steel structure design proposals, providing some guidance to slide the ball for practical engineering design hinged bearing on steel beams bear concentrated loads at fixed, when the load acting on the flange, where the flange of the horizontal section of the web and the web site of the junction, should have sufficient resistance to vertical partial pressures. The partial pressure of the area subjected to the vertical web of the horizontal cross section, for the vertical stress distribution in the product of the assumed length of the horizontal cross section of the web thickness on the checking, and assume that the vertical stress in the horizontal cross section is uniformly distributed. If the calculation of the vertical section of the local anti-bearing capacity is insufficient, you can magnify the vertical load bearing pad length, or where to set the web stiffeners. Slide ball bearing hinge, swing hinge pillar bearing sliding ball joint bearing, put one in the form of concrete columns also hinge pin hinge, which can be used to provide a considerable amount of deformation due to shrinkage and creep to accommodate temperature changes bearer and the beam length allowable bearing potential changes caused by subsidence. Britain had to put the hinge bearing column tests conducted research model. Test basic conclusion is: the applied load 300KN, overloaded or destroyed bridge over the safety factor of displacement under very high; load up 1500KN, the holder of the rotational angle of up to 11.5o ball bearing hinges, the stress exceeds the ultimate strength of concrete Concrete several times, without any danger of signal failure; the same time as increasing the bearing steel bending stiffness, reinforced through the neck can be reduced. According to the test structure was designed to make recommendations as long neck reinforced to withstand the stress of installation and processing requirements to the. [Slide] stability ball bearing hinge is one of the elements of steel structure engineering design considerations need to focus on engineering accident case in real life due to the instability caused by the steel is greater, such as flat-American Stadium 92m Hartford City × 110m grid structure, and suddenly falling to the ground in 1978, is due to strut buckling; 1988 have occurred in our country 13 · 2m × 18 · 0m steel truss webs due to lack of steady slump in the construction process accidents; January 3, 2010 in the afternoon, Kunming new airport 38m steel bridge span suddenly collapsed, killing seven people were killed and eight people injured, 26 people were slightly injured ball bearing hinge professional manufacturers to Guangrun because steel bridge Suddenly structural support system instability, 8m high bridge then collapsed down. As can be seen from the above case, [slide] steel ball bearing hinge FAILURE usually due to their irrational supply structure design seismic ball bearing hinge specialty materials, due to the presence of structural design flaws, to eliminate this fundamentally Class accident occurred, steel stability design is the key. [Slide ball bearing hinge] GPZ (111) damping pot bearings GPZ (111) is one of the damping pot bearings Guangrun Hebei Hengshui Rubber Co., Ltd. production bearing products, is a kind of energy dissipation damping effect of the bridge support for basic intensity 8 degrees for the bridge project area. This class has a one-way bearing activities (DX-type) and fixed (GD type) of two types. [Slide] bearing ball bearing hinge design parameters 1) Design of vertical bearing capacity of 0.8--80MN, divided into 31 specifications. 2) Design horizontal bearing: Fixed bearing in each direction and a one-way bearing activities of non-sliding direction (perpendicular to the longitudinal direction of the guide block) level for bearing design vertical bearing capacity of 20%. 3) Design Corner bit 0.02rad.
