Jacking and pulling device and method for adjusting steel truss girder closure gap
The invention relates to the technical field of bridge construction, and discloses a construction method for adjusting and controlling a closure position of a steel truss girder. The method comprisesa supporting seat, a jacking seat and a jack. The supporting seat and the jacking seat are connected with a closure gap steel truss girder. The supporting seat and the jacking seat are connected withthe closure gap steel truss girder through high-strength bolts. According to a jacking and pulling device for adjusting the steel truss girder closure gap, the steel truss girder is jacked or pulled to be close in a jack position adjusting mode, a longitudinal coordinate of cantilever closure of the steel truss girder is guaranteed, and the closure resisting difficulty of a steel girder is lowered. On the premise that safety is guaranteed, a large number of temporary supports and inhaul cables are saved, cost is saved, and a construction progress is accelerated.
本发明涉及桥梁建设技术领域，公开了一种钢桁梁合龙位置的调节控制的施工方法。本发明包括支承座，顶拉座，千斤顶。所述支承座和顶拉座与合龙口钢桁梁连接；所述支承座和顶拉座与合龙口钢桁梁连接方式为高强螺栓连接；所述钢桁梁合龙口调整的顶拉装置采用千斤顶调整位置的方式对钢桁梁进行顶推或拉近作用保证钢桁梁悬臂合龙的纵向坐标，降低钢梁抗合龙难度。本发明在保证安全的前提下节省了大量的临时支架、拉索的安装使用，节省了成本，加快了施工进度。
