Variable-breadth movable support and construction method thereof
The invention relates to a variable-breadth movable support and a construction method thereof. A poured lower-layer railway concrete beam is used as a bearing, and an upper-layer box girder construction platform capable of moving longitudinally and transversely is used. The variable-breadth movable support has the advantages of all tubular pile supports, and longitudinal moving wheel sets and transverse moving trolleys are installed at the bottom of the support so that the purposes of longitudinal hole passing and transverse breadth passing of the movable support can be achieved. Secondly, inorder to avoid a highway frame pier capping beam, side wing formworks of the movable support are made into bendable structures, and supporting stand columns are designed to be telescopic stand columns; and in the hole passing or breadth passing process, the height of a body of the whole movable support is reduced in a manner that the side wing formworks are rotatably bent and the movable support is integrally lowered, so that it is guaranteed that the movable support can smoothly pass through a highway frame pier door opening. The operation mechanization degree of the whole movable support ishigh.
本发明涉及一种变幅式移动支架及其施工方法，利用已浇筑下层铁路混凝土梁作支承，可纵、横向移动的上层箱梁施工平台。具备了所有管桩支架的优点，并在支架底部安装有纵移轮组和横移台车，以此来实现移动支架的纵向过孔以及横向过幅的目的；其次为避开公路框架墩盖梁，移动支架侧翼模做成可弯折结构，支撑立柱设计为可伸缩式立柱，在过孔或过幅时，采用侧翼模旋转折弯+移动支架整体下降的方式，将整个移动支架架体高度降低，从而保证移动支架能够顺利通过公路框架墩门洞，整个移动支架操作机械化程度高。
