Hao-engineering rubber _ fixed hinge bracket _ hinged stand by Hao-engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, spherical steel ball bearing hinge bearing hinge bearing, and the slide plate is supported by a circular elastomer composition basin fathers, only the insertion-type elastomer such as a lower seat plate side of the intermediate tank with a sealing elastomer dry plate in the middle of the top plate do not know embedded in a protruding structure of the intermediate steel plate and the upper seat of a configuration of part of the petals. Such activity of the carriage is moved above the level of the sliding plate to the matter, the use of the full range of the rotation function to complete the elastomeric seal, and a fixed abutment, the intermediate plate is embedded in the upper plate to interact directly with the excel on the small plates are replaced only by deformation of the elastomer seal into the rotation function. In the bottom of the basin of the top surface of the rubber sheet insertion compression rings, wooden thing is to organize the elastomer is extruded from the gap under the bottom pot of weeks to avoid the intermediate steel. The late 1950s began to develop abroad and applied ball joint bearing, ball bearing hinge in 1959 successfully developed in Germany and used on the highway bridge, a long time by the operator, and achieved good results the future of the world have specialized manufacturers have pot bearings, and bearing design tonnage is also increasing, the standard design of Japan in 1976, there 0.5-5mn pot bearings, our Ministry of Railways since 1975 to The performance ball bearing hinge conducted a comprehensive study and design completed Red River railway cable-stayed bridge with the bearing, and with the 1990 completion of the industry standard "highway bridge rubber bearing basin" (JT 3141- 90) the development of seismic damping hinged seat, were developed in 1999 to form a new industry standard, "highway bridge rubber bearing" carrying capacity bearing the original standard 1000-2000kn, increased to 1000KN, expand the scope of use, at present, the ball bearing hinges shall be subject to a wide range of applications on our roads and bridges, and roads and bridges has become one of the main bearing formation, the new industry standard is being revised. Damping structure is applied using constructed with isolation function at the supports, at the supports, generally adopt LRB or rubber bearing, namely isolation and damping integral damping rubber bearings. Using damping structures such as bridges deformation can make to improve performance and energy absorption while. Can also contribute to multi-span continuous and seamless development. Supports various components should be kept intact, clean, at least once every six months living hinge bearing, bearing clearance around the oil, garbage, prevent water, snow, ensure seat to work properly. Rolling bearing rolling surfaces should be regularly lubricated before oiled, rolling surface should be clean. Bearing steel to rust corrosion. In addition to the hinge axis and the rolling surface of the fixed hinged seat, and the rest should be made part of the anti-rust paint brush, timely tightening bolts steel bearing combination ministries, the support plate smooth and firm.
