Finished steel truss bearing _ _ unidirectional activity bearing professional manufacturers of steel ball bearings supplied by the grid HaoTong Engineering Rubber Co., Ltd. Hengshui. Finished steel truss bearing _ _ unidirectional activity bearing professional manufacturers of steel ball bearings are grid Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) launched this new upgrade, the above picture is for reference only, please You call Tel picture on this page or to obtain the latest information, contact: Liu. Steel truss bearing raw data collation and save truss steel bearings, master design conditions and installation of steel truss bearing construction status, changes and repair records and other information on the full bridge occurred in the past, to understand the steel mesh rack mount functional status and degree of variation, selection and method of repair time, though is a very complicated, complex and its important work of maintenance and management of the fixed grid of steel ball bearings, but this is the kind of future management instructive valuable information, so I hope the information bridge full bridge design conditions and when completed will be collected and collated and reflected in future maintenance and management, save the file and resume information in a relatively long time to come down very important. These records should include the following: bridge name, including the area in the form of universal rotation bridge truss steel spherical bearings, line names, including schematic diagram of the bridge structure. Bearing steel grid form, dunks bearing type, bearing materials and steel grid layout and so on. Design conditions, including the steel truss bearing type, bearing materials and layout, and other design conditions, including the design of steel truss bearing reaction force, designed horizontal force, displacement, bearing characteristics and the use of standards and down steel center gap when the temperature conditions and measuring the amount of grid bearing. Bearing steel grid should be further study found that many problems, prostitution only in Japan related universities, research institutions have Earthquake Disaster Reduction Committee conducted a multi-center field, many in-depth research, has made significant progress, and the establishment of the station device Extended use of the direction of the long-span bridges. Bearing steel grid due to our roads and bridges in the study results starting station equipment and design methods of late, and foreign compared to a considerable distance one-way activity truss steel ball bearings, but China's vast territory, geological the situation is complex. This head-grams to just design ideas or just called design theory, steel truss bearing a strong earthquake in the case, even with just grams just taken a seismic measures designed many bridges to no avail. Steel truss bearing different earthquakes in different regions, the impact of the bridge structure are not the same, so simple that the introduction of foreign research style can not meet the conditions, must be based on domestic research results closely mediated a Our situation is not clear to many problems in the future should be kept for an in-depth study of the plane type very necessary, earthquake caused severe damage to the bridge, around the world, especially bearing steel grid Dai Zhen-prone countries in accordance with their actual situation customized nationally appropriate measures to bridge seismic design specifications and corresponding various configurations. But the conventional bearing steel grid carrying the dominant ideology designed by unanimous wants some initial resistance to improve the structural strength of the earthquake.
