Steel truss girder construction method, steel truss girder and bridge structure
The invention relates to a steel truss girder construction method, a steel truss girder and a bridge structure. The method comprises the steps that S1, modeling is conducted on the steel truss girder, and data information of all rod pieces of the steel truss girder is obtained and comprises rod piece assembling alignment data; s2, the steel truss girder is divided into a plurality of truss sections in the longitudinal bridge direction, and each truss section comprises a plurality of truss units in the transverse bridge direction; s3, welding of rod pieces in the truss sections is completed in a factory, and welding of joints at intersecting lines is included; and S4, the adjacent truss units are connected, the adjacent truss sections are welded, and the steel truss girder is obtained. According to the method, the steel truss girder is modeled through forward design of the BIM information technology, the positions of all rod pieces and tubular joints in the steel truss girder are more accurate, accurate positioning can be achieved, and the welding effect is guaranteed; the steel truss girder is divided into a plurality of truss sections, a modular assembly mode can be adopted, the truss sections are machined in a factory, tubular joints are welded in the factory, the welding effect and the welding quality can be guaranteed, the strength and the rigidity of the truss are guaranteed, the field welding requirement is lowered, and the construction efficiency is improved.
本发明涉及钢桁架梁施工方法及钢桁架梁、桥梁结构；S1：对钢桁架梁进行建模，获取钢桁架梁各杆件的数据信息，包括杆件拼装对位数据；S2：将钢桁架梁沿纵桥向分成多个桁架节段，各个桁架节段包含了横桥向的多个桁架单元；S3：在工厂完成桁架节段中杆件焊接，包括对相贯线处接头焊接；S4：将相邻的桁架单元进行连接，对相邻的桁架节段进行焊接，得到钢桁架梁。本发明采用BIM信息技术正向设计对钢桁架梁建模，钢桁架梁中各杆件以及相贯节点位置更准确，能够准确定位，保证焊接效果；且将钢桁架梁分为多个桁架节段，可采用模块化组装方式，桁架节段在工厂进行加工，相贯节点均在工厂进行焊接，可保证焊接效果及焊接质量，保证桁架强度及刚度，降低现场焊接要求，提高施工效率。
