[Slide] ball bearing hinge bearing laminated rubber tension and compression is designed to pull a screw to mount the roof and fell together at the center of the plate laminated rubber bearing. In order to meet the supply of bearing slide longitudinally sliding seismic universal ball joint bearing, but slipped between bearing plate and anchor gusset plate and stainless steel plate and PTFE slide set. Section design] [slide ball bearing hinge section design is reasonable directly related to the safety of the structure, cost and convenience of construction projects. After the structure is determined, you can make a preliminary estimate of the member section based on experience. Including assumptions beams, columns and other components to support cross-sectional shapes and sizes, usually steel beams selectable channels, rolled or welded h beam cross section and so on. According to the case load and bearing its section height is usually between the span of 1/20 ~ 1/50 selection. According to China's current steel flange width specification limits determined by the beam spacing between lateral support, try to avoid the calculation of the overall stability of steel beams. Determine the cross-sectional height and flange width, its plate thickness according to the specification of the structure of local stability to preliminary determination. Column section slenderness ratio according to estimates usually 50≤λ≤80, then consider the different stress situation, choose section in the form of steel and other steel or h. [Slide ball bearing hinge tension and compression] pot pot holder bearing tension and compression, usually achieved through a fixed pot bearing center wearing a prestressed reinforcement (prestressed anchor) approach. Prestressed prestressing steel shall be 1.2 times the pulling force to ensure seat not because of bolt elongation disengaged. Prestressed anchor rotation axis can also be set in the pot bearings on both sides, and for pot bearings bearing activities, prestressed rod can only be set on both sides of the shaft bearing. By prestressing steel fixed support center in the seat height range should be equipped with a closed casing production and sales of the three ball bearing hinge to form a rotating seat cushion to make the buffer layer. [Slide] ball bearing hinge steel industry development status of steel represents the trend of world architectural development of large new high-rise steel buildings are constantly emerging. Stable and rapid economic development of the iron and steel industry, especially from 1996 steel production exceeded 100 million tons in the future, more than 500 million tons last year, the steel industry development policy has significant change ball bearing hinges, and the advantages of steel has been attention and rapid development. Major projects, the widespread use of landmark projects, presents a universal phenomenon. [Slide] ball bearing hinge hybrid bearing, in addition to a rubber bearings to adapt the following main features, due to the rotation function is separated from the rubber bearings, the rotation range of adaptation can be further expanded with rubber bearings compared to the same time increase After the rubber closures, not only has the ability to withstand the vertical loads, and to adapt to the requirements of the rotation function, vertical load bearing function 1. 2. Horizontal displacement adaptation function (usually) 3. elastic support function (earthquake) [sliding ball joint support Block] As a result of the sealing rubber cap structure (BP · B structure) is deformed to absorb the deformation of the bridge of the rotation, so rubber bearing itself does not affect the rotation of the transfer. DOF structure significantly increased costs have also been reduced. [Slide ball bearing hinge bearing highway bridge construction]: [] slide ball bearing hinge factory requirements: First, to ensure the quality of products is an important prerequisite bearing bearing installation and maintenance of the whole. So high-quality universal ball joint bearing sliding seismic finished, before bearing factory, the response of each batch of product quality inspection before delivery. Factory inspection by factory quality control department, confirmed after passing the factory, the factory should be accompanied by the product quality certification document, together with bearing specifications and other relevant information in order to use the unit for acceptance and sampling. Three-ball hinge support production and sales, ball bearing hinges, rubber-Run-Run Company is provided by Hengshui Rubber Co. project. Hengshui Guangrun Engineering Rubber Co. (www.grgcxj.cn) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Guangrun Rubber Company and you work into the brilliant, for a better future!
