Construction method of integral node structure for connecting truss girders with unequal widths
The invention relates to a construction method of an integral node structure for connecting truss girders with unequal widths, and belongs to the technical field of bridge construction. Comprising the following steps that S1, a temporary connecting section is welded to the tail end of a constructed steel truss girder; s2, the steel truss girder to be constructed and the constructed steel truss girder are connected into a whole through the temporary connecting section; s3, after construction of one section of steel truss girder in the step S2 is completed, the temporary connecting section is dismantled to form an expansion joint; s4, the temporary connecting section is welded to the tail end of the steel truss girder constructed in the step S3 again; s5, the steps S2 to S4 are repeated till overall construction of the truss girder is completed; the steel truss girder to be constructed is temporarily consolidated to the adjacent constructed steel truss girder, so that the construction period and cost for erecting a bracket are saved, and the problems that the existing steel truss girder is relatively high in overwater construction difficulty and a bracket needs to be additionally arranged for supporting are solved.
本发明涉及一种连接不等宽桁架梁的整体式节点构造的施工方法，属于桥梁施工技术领域。包括以下步骤：S1：在已施工完成的钢桁梁尾端焊接临时连接段；S2：将即将施工的钢桁梁通过临时连接段与已施工完成的钢桁梁连接成一个整体；S3：当步骤S2中的一节钢桁梁施工完成后拆除临时连接段形成伸缩缝；S4：将步骤S3中已施工完成的钢桁梁尾端再次焊接临时连接段；S5：重复上述步骤S2至S4，直至桁架梁整体施工完成；本发明将要施工的钢桁梁临时固结于相邻已施工完成的钢桁梁，从而省去搭设支架的工期和费用，解决了现有的钢桁梁水上施工难度较大，需要额外设置支架来进行支撑的问题。
