Method for installing upper cross beam of bridge tower steel structure
The invention discloses a method for installing an upper cross beam of a bridge tower steel structure, which relates to the technical field of bridge construction, and comprises the following steps: constructing embedded parts, installing a lifting bracket, laying a sliding rail on the top surface of a box girder, placing a sliding plate on the sliding rail, hoisting to a bridge floor by using a crane, splicing into a whole, and falling on the sliding plate. The sliding plate and the upper cross beam are fixedly connected in a welded mode, four lifting lugs are installed on the top face of the upper cross beam, two sets of sliding devices are installed, and the two sets of sliding devices are controlled by one set of system so as to guarantee synchronous sliding. External restriction interference is small; a sliding lifting method is adopted, and high-altitude installation of a large component can be achieved under the condition that a large floating crane cannot enter a site.
本发明公开了一种桥塔钢结构上横梁安装的方法，涉及桥梁施工技术领域，包括施工预埋件、安装提升支架、在箱梁的顶面铺设滑移轨道，于滑移轨道上放置滑板、采用吊机吊至桥面拼接成整体后落于滑板上，滑板与上横梁采用焊接连接固定、于上横梁的顶面安装四个提升吊耳，并安装两套滑移设备，两套滑移设备由一套系统进行控制，以保证同步滑行等步骤，本发明采用滑移提升方法，可以取代常规的吊装设备，减少吊装所需的场地空间，外界制约干扰较小；采用滑移提升方法，在大型浮吊无法进场的情况下，可以实现大型构件高空安装。
