Steel box girder with grid structure and splicing method of segments of steel box girder
A steel box girder with a grid structure comprises a top plate, a bottom plate and web plates located on the two sides of the top plate and the two sides of the bottom plate, the grid structure is connected between the top plate and the bottom plate, and the grid structure is formed by connecting a plurality of truss monomer arrays; each truss single body is in a rectangular pyramid shape and is formed by connecting four connecting nodes and four connecting rods, and the four connecting nodes are welded to the top plate and the bottom plate respectively. Due to the fact that each face of each truss single body is of a triangular stable structure, the truss single bodies and the grid structure have good stability and can bear forward and oblique loads, the bearing capacity, rigidity and distortion resistance of the truss single bodies and the grid structure are all superior to those of a rectangular grid structure composed of transverse partition plates and longitudinal partition plates, and under the same bearing capacity, the truss single bodies and the grid structure are not prone to deformation. The steel consumption of the grid structure is less, and the manufacturing cost is lower. According to the splicing method of the steel box girder sections, the connecting joints are used as oppositely-inserted structures, and rapid splicing of the steel box girder sections is achieved through the telescopic rods.
一种具有网架结构的钢箱梁，包括顶板、底板、以及位于顶板、底板两侧的腹板，在顶板与底板之间连接有网架结构，网架结构由多个桁架单体阵列连接而成；桁架单体呈四棱锥形，由四个连接节点和四根连接杆连接而成，其中，四个连接节点分别焊接在顶板和底板上。由于桁架单体的每一面都具有三角形的稳定结构，因此桁架单体以及网架结构具有良好的稳定性，能够承载正向、斜向的载荷，其承载能力、刚性和抗扭曲性都优于由横隔板和纵隔板构成的矩形网格结构，而且在同样的承载能力下，网架结构的用钢量更少、制造成本更低。一种钢箱梁节段的拼接方法，将连接节点作为对插结构，并通过伸缩杆实现了各钢箱梁节段的快速拼接。
