桥梁橡胶支座厂家是连接桥梁上部结构和下部结构的重要构件,可谓一座桥梁的咽喉地点,关系严重,一旦呈现病害,将影响到上下部结构的使用寿命和交通安全。现在,新建的公路桥梁简直悉数选用桥梁橡胶支座厂家。特别是高速公路桥梁,桥梁橡胶支座厂家的用量大,病害多,事故频频产生,支座病害处治及替换刻不容缓。
Bridge rubber bearing manufacturer is an important component connecting the superstructure and substructure of the bridge. It can be said that the throat of a bridge has a serious relationship. Once the disease appears, it will affect the service life and traffic safety of the superstructure and substructure. Now, almost all new highway bridges use bridge rubber bearing manufacturers. Especially for highway bridges, the amount of rubber bearings used by bridge manufacturers is large, with many diseases and frequent accidents. Therefore, it is urgent to treat and replace the bearing diseases.
扁型千斤顶法把超薄的液压千斤顶安放在主梁与盖梁的狭小的空间内,直接顶升梁体,利用百分表观测梁体上升的速度,以保证桥跨各梁体受力均匀同步提高。该办法是现在使用广泛的顶升办法。鞍型支架法,用桥墩自身做支撑在盖梁上搭设支架。
规划成“鞍型支架”,放置千斤顶来顶升梁体。枕木满布式支架法,在地面上设置枕木,以枕木为根底,设置满布式或部分木支架至桥梁梁体处,在支架上安置千斤顶顶升梁体。鞍型支架法,用桥墩自身做支撑在盖梁上搭设支架,规划成“鞍型支架”,放置千斤顶来顶升梁体。
为保证一孔桥梁的全体受力及同步顶升,应按照规划文件计算桥面、中梁、边梁、护栏等上部构造的重量,然后根据全体重量均衡的准则进行配载,一般选用车辆均匀安置配载,保证顶升过程中受力均衡。
搭设的顶升支架要有满足的强度刚度和稳定性保证在梁被顶起的时候支架不呈现倒塌倾斜沉降应小且均匀必要时在支架底设置混凝土根底。油压千斤顶应保证油路突出,各串联千斤顶油压均匀工作状态正常以免在施工过程中呈现不均匀顶升。http://www.hbyanye.com/
