Steel truss bearing steel truss mount examination should pay particular attention to the site and matters bearing on the activities of steel grid, the displacement situation combined with outside air temperature checks bearing checking, mainly to check the fulcrum beam end changes in beam end gap between the abutment back. When the steel truss bearing pedestal base near contentment cement mortar change, even if i Macau telescopic device does not appear at the elevation and other reasons beyond bearing steel grid should also be checked. On the curved bridge, line, parallel to the bridge or not cool case, since the steel truss bearing mounting direction and the only direction is likely to cause a different bearing damage and abnormal sound problem, so deal with bearing on the 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, while leaking steel truss bearing pedestal 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 floor steel beams welded parts, so pay special attention. The maintenance aspect, the sliding surface, rolling surface is not flat, dirty fixed grid of vertical damping steel ball bearings, dust and other foreign matter not timely cleaning, fasteners loose reinforcement is not timely, because the waterproof device makes bearing defects or link area water corrosion, accelerated aging processes. Again is due to the piers, abutments uneven subsidence, tilt and horizontal shift of the upper structure, vibration displacement and other superstructure steel truss bearing directly affect the normal use. Bearing steel grid can make safe and effective use of normal, it should strengthen the holder of regular inspection and repair and reinforcement work, and dedicated to the steel truss seat for the daily management and maintenance purposes, put into practice style is very difficult, it is usually combined with other conservation work with bridge steel truss seat and pay attention to the site to check the integrity of its own two-way sliding grid damping steel ball bearings, observing the presence or absence of dislocation, void, activities Supports bi-directional activity is flexible grid damping steel ball bearings, fixed bearing is displaced, the amount of displacement is normal, whether fixed grid connection intact damping steel ball bearings, bearing pad crushed stone concrete or without rupture dust deposition and rubber bearings is aging cracking, deformation is uniform, steel truss bearing steel pots, ball bearings with or without the appearance of rust dust cover is intact and so change phenomenon.
