Slide ball bearing hinge mechanical properties of steel beam steel beam damping good quality two-way hinge support in its symmetry axis in the plane of the lateral loads, generally only produce bending moment, shear and deflection in the plane. However, due to the cross-section steel beam is usually high, narrow beam, or trough, lateral bending stiffness and torsional rigidity is small, it may happen lateral bending and torsional buckling lose overall stability [2]. For bi-directional hinge bearing slide composite beam than the national standard, when relatively thin webs or flanges, but also may occur in the compression zone of local instability and destruction. Slide ball bearing hinge, therefore, should be fully taken into account when designing the steel beam and were checking their bending stress and shear strength, deflection, overall stability and local stability. Sliding ball joints such as the three-hinged arch bearing species can eliminate compression of an elastic hinge arch, stress and temperature changes caused by the displacement of foundation settlement, while the reinforced concrete hinge hinge cheaper than metal, construction is relatively easy and does not require special conservation . Slide ball bearing hinge design of reinforced concrete in addition to the factors, the effect of the hinge good or bad, depends largely on the detail treatment of its construction. Due to unreasonable construction process sliding ball joint bearing hinge, is not ideal, but the example often lead to structural damage exists. Because concrete hinge has its unique advantages bidirectional hinge support, all at home and abroad have a lot of engineering and technical personnel of the long-term comparison and analysis, made a lot of good advice and design. Slide ball bearing hinge hinge common type of concrete reinforced concrete hinge according to its structural form, there are a variety of types of hinge, in the case of a lot to be used on various occasions. According to Qi unidirectional rotating rotation requirements and bi-directional rotation of the points. According to the information, some of the commonly used reinforced concrete hinges largely providers can be summarized into the following categories. [Slide ball bearing hinge] Therefore polyether urethane rubber disc should have sufficient rigidity to withstand the vertical loads, excessive deformation does not occur, and also sufficient flexibility to accommodate the needs of the corner, but not void, and no excessive stress is passed to another member (such as PTFE skateboard), [slide] ball bearing hinge displacement remains flat PTFE by stainless steel plate and sliding to achieve. Meanwhile, polyether polyurethane disc should be fixed position, so as not to slip away from the correct location. [Slide ball bearing hinge] {8} According to literature reports, the first disc holder designed by R.Fyfe Canadian products around the 1980s. This class is a polyether urethane rubber bearings instead of neoprene rubber bearings and a disc of natural rubber materials, its products in the "Mid-Atlantic States SCEF106 order" classified as large-tonnage universal savings seat dish mount a class. [Slide] ball bearing hinges for welded joints, weld size and form should comply with the relevant provisions of the existing norms. Such as the selection and should be connected to the metal electrode material strength adapt, e43 corresponding q235, e50 corresponding q345. In addition, the welding seam design should consider the possible center of gravity and the center of gravity closer to the connecting member. For Bolted Joints, ordinary bolt shear due to its poor performance, use only a minor part of the structure. Relatively widespread use of high-strength bolts rolling two-way hinge support a broader range commonly s8.8 and s10.9 two intensity levels, high strength bolts connecting points according to the mechanical characteristics of two kinds of pressure and friction-type connection, the design should Note the difference between the two calculation methods. Whichever webs may simply increase the thickness of the beam web thickness of 4 mm, and then press the corresponding checking our current specifications.
