Temporary connecting structure for replacing steel truss girder into steel box girder, and girder replacing method
The invention relates to a temporary connecting structure for replacing a steel truss girder into a steel box girder, and a girder replacing method, and relates to the technical field of bridge maintenance and transformation. The temporary connecting structure is used for connecting a new girder section and an old girder section which have different section sizes. The temporary connecting structure is of a steel box structure and is divided into three sections, namely a new girder butt joint section, a transition section and an old girder butt joint section in sequence; the new girder butt joint section is provided with a new girder connector capable of being in uniform-section butt joint with the new girder section, and the new girder connector is detachably connected to the new girder section; and the old girder butt joint section is provided with an old girder connector capable of being in uniform-section butt joint with the old girder section, and the old girder connector is fixedly connected to the old girder section. The invention discloses a girder replacing method based on the temporary connecting structure. The new girder section and the old beam girder can be firmly connected, mounting and dismounting are convenient, and girder replacing construction is convenient.
本申请涉及一种更换钢桁梁为钢箱梁的临时连接结构及换梁方法，涉及桥梁维修改造技术领域，用于连接不同截面尺寸的新梁节段和旧梁节段，临时连接结构为钢箱结构，其分为三段，依次为新梁对接段、过渡段和旧梁对接段，新梁对接段具有能够与新梁节段等截面对接的新梁接口，新梁接口可拆卸连接于新梁节段；旧梁对接段具有能够与旧梁节段等截面对接的旧梁接口，旧梁接口固定连接于旧梁节段。本申请公开了一种基于上述临时连接结构的换梁方法，能够牢固连接新梁段和旧梁段，且便于安装和拆卸，便于换梁施工。
