Hao Tong Engineering Rubber | laminated rubber bearings | rubber bearings 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 down demolition After the bearing plate, bearing the appearance inspection, and timely installation of bearing outer dust cover, when bearing beam and pier with welded connections, should now stand accurately positioned, with symmetrical intermittent welding, The lower bearing plate and on the piers embedded steel welding, welding should prevent burns and concrete circular bearing laminated rubber bearing, spherical bearing courses specific operation mounted by the relevant norms and standards. Stand-in relation to the safety and durability of major structural components of the bridge structure, and therefore need to ensure that the load transfer in the usual bridge bearing deformation adaptation functions. Those changes holder of injury and aging. Most are caused by the impact of complex factors and. If you find rubber bearing steel truss bearing changes and take prompt measures to control the majority of its development and reduce the function of the deformation, but if shelved matter, bearing deformation will become increasingly large, which not only cause bearing function reduce, but will give the upper and lower parts of the bridge structure proxy very bad influence, so pay attention to check in daily, regular maintenance rubber bearings, even if damage is found to repair or replacement of the maintenance and management is very important. Form the lower part of the bridge structure, bridge bearing repair or replacement, the use of pre-liter methods and construction scaffolding, the form should be based on the lower part of the bridge structure is concrete or steel structure, seat targeted research. When jacking construction, bearing repair and construction, on many occasions to consider the beam from the top, then you must pay attention to the local bearing stress jacking equipment location, soldiers should take a different approach to strengthen the structure of different materials. To be from the top of the main beam in bear parts should check their jack whether to allow the top, measures must be taken to strengthen the time. Jacking operations are generally due to the lower construction height between the main beam and are relatively small. It should be based on the actual need to select the appropriate jack type. If the original design of the bridge is not considered a placeholder placed jacks, construction scaffolding erection is usually considered to achieve. If you use the beams were jacking end, should also end composite beam for safety checking to avoid the destruction of concrete edge beam end laminated rubber bearings, when performing lifting operations, you must compare the amount of top-up analysis, Deck does not appear possible to make cracks and adversely affect the bridge superstructure, has reached a reasonable value, meet the requirements of the construction.
