Rigid frame bridge girder closure opening jacking force applying device and closure construction method
The invention relates to the technical field of bridge engineering, and discloses a rigid frame bridge girder closure opening jacking force applying device and a closure construction method, and the rigid frame bridge girder closure opening jacking force applying device comprises a supporting assembly, an opposite jacking locking assembly and a girder closure construction method based on corresponding facilities. The supporting assembly has the following advantages and effects that the supporting assembly is arranged between the top plate and the bottom plate, the supporting beams of the supporting assembly are supported on concrete of the top plate and the bottom plate, and huge locking force is evenly diffused to the top plate and the bottom plate of the main beam through the concrete contact faces of the supporting beams and the top plate and the bottom plate; compared with a mode of directly supporting on a top plate, a bottom plate and a web plate of the main beam or supporting on a bracket and an embedded part or transferring force by pouring a concrete tooth block, the device has the advantages of light structure, definite stress, high bearing capacity, simplicity and convenience in operation, no influence on concrete pouring of the closure gap, no tensile stress crack of the main beam and low cost.
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合龙施工方法，包括支撑组件、对顶锁定组件，以及基于相应设施的主梁合龙施工方法。本发明具有以下优点和效果：本发明在顶板和底板之间设置支撑组件，支撑组件的支撑梁支撑在顶板和底板混凝土上，支撑梁将巨大的锁定力通过与顶板和底板的混凝土接触面均匀地扩散到主梁的顶板和底板上，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，又或是通过浇筑混凝土齿块传力的方式具有结构轻巧，受力明确，承载力强，操作简便，不影响合龙口混凝土浇筑，主梁不产生拉应力裂缝，成本低的优势。
