Continuous rigid frame side span steel beam erecting method
The invention discloses a continuous rigid frame side span steel beam erecting method which comprises the steps that firstly, a stress conversion frame is installed on a concrete beam section, a first adjusting jack and a hoist crane are installed on the stress conversion frame, and the first adjusting jack is connected with a sling; installing a second adjusting jack on the bridge pier of the side span; then a lifting lug is welded to one end of the steel beam, the whole steel beam is lifted to the installation position through a floating crane, and one end of the steel beam is supported on a second adjusting jack; connecting the lifting lugs by using a sling, and finishing stress conversion through a first adjusting jack; then the position of the steel beam is adjusted through a hoist crane, a first adjusting jack and a second adjusting jack, then the steel beam is welded to the steel connector of the concrete beam section, and concrete is poured between the steel beam and the concrete beam section; and finally dismounting the second adjusting jack and the stress conversion frame. The hoisting device has the effects of facilitating hoisting and positioning of the steel beam and improving the hoisting speed of the steel beam.
本发明公开了一种连续刚构边跨钢梁架设方法，首先在混凝土梁段上安装应力转换架，应力转换架上安装第一调节千斤顶和葫芦吊，第一调节千斤顶连接有吊索；然后在边跨的桥墩上安装第二调节千斤顶；之后在钢梁的一端焊接有吊耳，通过浮吊将钢梁整体吊至安装位置，钢梁的一端支撑于第二调节千斤顶上；然后使用吊索连接吊耳，并通过第一调节千斤顶完成应力转换；之后通过葫芦吊、第一调节千斤顶和第二调节千斤顶调节钢梁的位置，然后将钢梁与混凝土梁段的钢接头焊接，再在钢梁和混凝土梁段之间浇筑混凝土；最后拆除第二调节千斤顶和应力转换架。本申请具有方便钢梁的吊装定位，提高钢梁的吊装速度的效果。
