Steel truss supports, Hao Tong is a professional manufacturer of steel bearing fixed grid provided by Hao-engineered rubber. Steel truss supports, Hao Tong is a professional manufacturer of bearings are fixed grid Steel Engineering Rubber Co., Ltd. Hengshui HaoTong (www.htgcxj.com) 2014 has been newly upgraded launched bearing steel mesh steel grid rack mount examination should pay particular attention to the site and matters bearing on the activities of steel grid, the gap displacement situation combined with outside air temperature checks bearing inspection, the inspection beam main beam ends at the end of the fulcrum between the station back change. When bearing steel grid base near contentment cement mortar base changes, even if i Macau telescopic device does not appear at height and other reasons beyond bearing steel grid should also be checked. On the curved bridge, bridge or parallel polyline cool occasions, due to the installation of steel truss bearing a different direction and the only direction is likely to cause bearing damage and abnormal sound problem, so deal with right bearing steel grid installation directions for further examination to verify. Side span is significantly shorter compared with the mid-span continuous girder bridge, the bridge of the bevel and the small span of the Bay Bridge because of the possibility of the emergence of negative rebate, but also prone to produce steel truss bearing damage, should be detailed examination. Under the telescopic device from dust at the opportunity and the water leak, and cause corrosion of steel bearing steel truss members, particularly the use of antifreeze in areas such effects will be greater grid Steel holder, while leaking steel structural truss bearing base cement mortar aging, cracking and crushing steel grid is one of the reasons for failure to use seat. Should also be careful to check. When the steel truss bearing swivel function and mobility emerge failure, most likely caused by damage to the steel beam tension and compression plate weld steel truss supports, so pay special attention. Adjust individual grid Steel bearings, replace laminated rubber bearings, steel truss supports, using the following method Felt cushion seat, set the jack at the bottom beam steel truss bearing compartment next to or at the end of hum the Slab adapted regularly to make holder void entertained, be adjusted or replaced after people. Adjustment is completed or after the new seat on the right, off the beam to the use position, high seat when needed, can be used in several ways depending on the size of the following high beams. Pad into steel or cast steel plate, replace the grid Steel laminated rubber bearings sliding bearings, in situ reinforced concrete pouring steel grid support cushion stone, stone pad height settings as needed, should generally be greater than 100mm. Research Matters repair works. Bridge bearings Once damaged, it must make a judgment according to their degree of damage, and make treatment plan as soon as possible, can not hold no matter what. Because most of the steel truss bridge bearings are disposed in a relatively narrow part of the space, if the decision is reinforced or replaced, will be bound by these conditions, and such work is often required to complete within a short period of time. To safely, quickly, and quality and quantity.
