Seismic ball bearing manufacturers 13,833,855,982, ball bearing seismic grid provided by Hao-engineering rubber. Seismic ball bearing manufacturers 13,833,855,982, ball bearing seismic grid is Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) 2014 年 launched a new upgraded pendulum column bearing steel grid whether the relative position of the components accurately, the force is uniform. Whether roller bearing steel grid roller allowed crawling, skewed. Whether rocking shaft bearing steel grid tilt. Steel cast concrete pendulum bearing steel grid column note the presence or absence of concrete peeling, cracking, exposed tendons and steel with or without corrosion. In regular testing stage, bearing steel grid defect site, type, nature bidirectional seismic ball bearing, range, quantity and description of the extent of the external situation carefully and provide typical defects of photographs and pictures. Multi requirements for special bridge inspection report should clearly state the reasons inspection. Special investigation. The so-called special investigation is in regular checks, periodic inspection after bearing steel grid should be based on the status and nature of the grid earthquake damaged ball bearings for dictation steel truss bridge or a particular seat, using the instrument to coordinate awakened scene testing, load testing machine other auxiliary seismic testing multi ball bearings, made a detailed survey conducted during the inspection, emergency treatment decisions goods repair methods and to obtain design data repair two investigations by the special investigation. Furthermore, the survey items bearing steel grid checking operations may include environmental conditions, traffic, bridge bearings MI characteristics and conditions. Small changes in environmental conditions in the short term, it is usually in the daily inspection remove it. However, when the results of the comprehensive determination of periodic inspection, weather conditions, the bridge features steel truss bearing status has become necessary items. Special examination should be based on damaged condition and the nature of bridge bearings, bearing steel grid using field test equipment and other auxiliary test checks bearing steel grid to analyze the status quo, forming a conclusion. Steel truss bearing special examination report shall include the following main elements: general overview of inspection, including the basic situation of bridge bearings, the organization checks, time, Beijing and inspection processes. Steel truss bridge bearing bearing describe the current state of technology, including project and methods sausage investigation, testing and inspection, testing and analysis of data and evaluation of the technical condition of the bridge abutment. Detailed description of the extent of damage and the cause of the examination site and proposed bridge bearing structural parts or the whole of the ball bearing seismic repair, strengthen or replace the advice motion. Typical defects and diseases and diseases of the photo and description. The term describes the application of professional standards defective condition, indicating the defect site, type, nature and scope.
