Municipal rigid frame bridge corbel bracket mechanism and finished bridge linear control method thereof
The invention relates to the technical field of bridge construction, in particular to a bracket bracket mechanism of a municipal rigid frame bridge and a bridge forming linear control method of the bracket bracket mechanism of the municipal rigid frame bridge. An upper support, a middle support and a lower support are sequentially and horizontally arranged on one side of a large-mileage overhanging part and a small-mileage overhanging part of the concrete pier body from top to bottom, the bracket bracket is rapidly assembled through a pin connecting assembly before being installed, and the bracket bracket and the concrete pier body are fixedly installed through hoisting equipment after assembly is completed. The pin connecting assembly is safely limited through the limiting assembly before hoisting, construction safety and operation convenience are improved, gaps and inelastic deformation of vertical rod pieces of the bracket under the prepressing load effect are eliminated through prepressing and deformation monitoring after the bracket bracket is installed, control over the construction process is facilitated, pouring on the bracket bracket is completed in three times, and the construction efficiency is improved. The structure is safe and stable.
本发明公开涉及桥梁施工技术领域，具体为一种市政刚构桥牛腿托架机构及其成桥线形控制方法，包括混凝土墩身、若干托架组件、销连组件和限位组件，混凝土墩身的大小里程悬挑部位一侧由上而下依次水平设有上部支座、中部支座和下部支座，在牛腿托架安装前通过销连组件对其进行快速的组装装配，装配结束后通过吊装设备将其与混凝土墩身进行固定安装，吊装之前通过限位组件对销连组件进行安全限位，提高施工安全和操作的便利性，在牛腿托架安装后通过预压和变形监测，消除预压荷载作用下托架各竖向杆件的间隙及非弹性变形，利于施工过程的控制，牛腿托架上分三次浇筑完成，结构安全稳固。
