Grid of steel supports, design and production of professional manufacturers, seismic grid steel bearing ball joint is provided by Hengshui HaoTong Engineering Rubber Company. Grid of steel supports, design and production of professional manufacturers, seismic grid steel bearing ball joints are Hengshui HaoTong Engineering Rubber Co. (www.htgcxj.com) launched this new upgrade, the above picture is only for reference, please call this page or contact phone picture on to obtain the latest information, contact: Liu. Steel truss bearing raw data collation and preservation, master design conditions bearing steel grid construction and installation conditions, changes and repair records and other information on the full bridge occurred in the past, to understand the function of the status quo bearing steel grid and the degree of change, repair time and the selected method of fixing the grid of steel ball bearings, although it is a very complicated one-way truss steel ball bearing slide, complicated, and important maintenance work, but this is A guiding significance for the future management of valuable information truss steel bearing, so I hope to information and full bridge design conditions when the bridge will be completed to collect and collate two-way truss steel ball bearing slide, and be reflected in future maintenance and management, the resume file and save this information in a relatively long period of time off is very important. These records should include the following: bridge name, including bridges form area, 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. It must not only requires seat location and extent of damage to figure out in advance, and after a full analysis and research for the surrounding environment and traffic conditions brought about by the construction period, the construction space, bridge structures, construction methods and construction equipment to do a reasonable choice, block diagram shown in repair work research matters. Bearing steel grid location and extent of damage. Location and extent of damage to the bearing steel grid will directly affect the repair method chosen, so the first thing to grasp is the seat causes of damage is important. Different causes of damage which repair method is also different, for example due to bearing steel grid itself bound damage and deformation structure, should be supplemented for its ability to ensure the displacement of the provisions of the bridge design. If you are due to irrational use of bearing steel grid forms, such as bridges longitudinal slope greater than specification, and direct use of shelving, steel truss supports, beams were leveled bottom damage, replace the steel mesh frame must be at the bottom of the beam bearing leveling treatment, then put on a seat designed only, and can not simply be replaced with one that will do something wrong, bearing damage caused by factors must be eliminated from the root. If the reason for the lower part of tectonic deformation caused, it must be taken into consideration to determine their future deformation Xu repair methods. That is, the repair method should be clear for the type, can not be stereotyped, otherwise fail to achieve the purpose and effect.
