Rigid frame bridge girder joint jacking force applying device and construction method
The invention relates to the technical field of bridge engineering, and discloses a rigid frame bridge girder joint jacking force applying device and a construction method. The device comprises a supporting tooth block, an opposite jacking assembly and a locking assembly. The invention also relates to the construction method based on corresponding facilities. The device has the following advantages and effects that: the supporting tooth block is arranged at the intersection position of a bottom plate and a web plate, the steel bar of the supporting tooth block and the steel bar of a beam section are bound together, and the concrete is also poured together, so that huge locking force is skillfully and uniformly diffused to the web plate and the bottom plate of a girder through two concrete contact surfaces. Compared with a mode that the device is directly supported on a top plate, the bottom plate and the web plate of the girder or supported on a bracket and an embedded part, the device has the advantages of being safe in structure, high in bearing capacity, convenient to construct and low in cost, and the overall structure of the girder is not affected even if the supporting tooth block is damaged.
本发明涉及桥梁工程技术领域，公开了一种刚构桥主梁合龙口顶力施加装置及施工方法，包括支撑齿块、对顶组件和锁定组件，以及基于相应设施的施工方法。本发明具有以下优点和效果：本发明在底板与腹板相交位置设置支撑齿块，支撑齿块的钢筋与梁段钢筋绑扎在一起，混凝土也浇筑在一起，巧妙的将巨大的锁定力通过两个混凝土接触面均匀地扩散到主梁的腹板和底板上，相对于直接撑在主梁顶底板和腹板上或支撑在牛腿和预埋件上具有结构安全，承载力强，施工方便，成本低的优势，即使支撑齿块破损也对主梁整体结构没有影响。
