Hao-engineering rubber, seismic spherical bearing walls finished, Baoshan bearing walls provided 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 bearing regular checks in principle, be traffic restrictions. Always check the use of visual methods can also be measured with simple tools, will soon fill in the bridge frequently check the disciplinary table, defect type site to check the level of the project. Shareholders and defects range and conservation work, propose appropriate protection measures for minor repairs, regular checks on major possessions bearing bearing any obvious defects, bearing activities are flexible, the amount of displacement is normal, bearing always check sometime per quarterly, if bearing defects and poor technical condition of development hinges mow, you should shorten the inspection cycle. Regular inspection, the so-called regular inspection, that a cargo twice a year, a period of not more than three years, the aim is to give the conservation and repair plans next year to provide information. Generally in the road along the bridge inspection program carried out. Mainly through the measuring device to investigate determined. Bridge bearings easily damaged due to the location, check in often difficult to be visually inspected, and therefore should be treated as regular inspections focus on examination of the site, the type of material used in bearing more rubber, PTFE plates, reinforced concrete walls bearing, particularly rubber and other polymer material life is relatively short, with particular its aging major periodic inspection. Whether normal working state bridge support. Once the changes in the new situation should be promptly cleaned or repaired outside and check the reason from the degree of change and the surrounding circumstances, as soon as possible to make a judgment whether to repair and strengthen the daily work style is very important. Bridge bearing damage causes are many seismic spherical bearing walls finished, generally considered the forces acting on the bearing and deformation often exceeds the design requirements exceed the design requirements is the main reason, but also the construction and quality management imperfect Reasons one, therefore, should be fully considered in the design of the sliding bearing walls bearing force wholesale, displacement and use of environmental seismic ball bearing hinge curtain manufacturer must also ensure construction quality. The main aspects of the type of bearing damage and its causes can be summarized as follows: bearing itself bearing itself deformation due to structural deformation of the main force curved bridge or ramp bridge complex, resulting in uneven stress concentration at the supports. Not dense or mortar base plate corrosion, processing quality control is lax, bearing itself is flawed. Bolts, nuts and shedding of the construction there is no deformation when tightened, corrosion, deformation, vibration is considered insufficient. Sliding surface or rolling surface corrosion.
