Fabricated steel bridge with built-in string structure
The invention relates to the technical field of highway bridges and culverts, in particular to a fabricated steel bridge with built-in string structures. The problems that an existing assembled highway steel bridge is too small in applicable span and too large in deflection are solved. The steel bridge is formed by connecting a truss, a bridge deck system and a string structure system, the bridge deck system is arranged on the truss, the string structure system comprises fixing devices and connecting pieces, the fixing devices are connected with an upper chord or a lower chord of each truss piece of the truss through bolts, and every two adjacent fixing devices are connected through the corresponding connecting piece; each fixing device comprises a channel steel connecting piece and a T-shaped connecting piece, the T-shaped connecting piece is arranged in the middle of the channel steel connecting piece, pin holes with different numbers and sizes are formed in a vertical connecting rod of the T-shaped connecting piece, and the vertical connecting rod of the T-shaped connecting piece is connected with one end of a steel pull rod through a pin shaft; the steel channel connecting pieces are vertically symmetrical, the truss pieces of the truss are connected into a whole through the through long bolts by the steel channel connecting pieces, and the steel bridge is in a multi-row or multi-layer or multi-row or multi-layer deck type or through type.
本发明涉及公路桥涵技术领域，涉及一种内置张弦机构的装配式钢桥。以解决现有装配化公路钢桥适用跨径过小和挠度过大的问题。本发明钢桥由桁架、桥面系和张弦系统连接组成，桥面系设置于桁架上，所述的张弦系统包括固定装置和连接件,固定装置通过螺栓与桁架的每个桁架片的上弦杆或者下弦杆相连接，相邻两个固定装置之间通过连接件连接；每个固定装置包括槽钢连接件和“T”形连接件，“T”形连接件设置于槽钢连接件的中部，“T”形连接件的竖向连接杆上开设数量大小不等的销孔，通过销轴与钢拉杆的一端连接；所述的槽钢连接件上下对称，并设置有多组，多组槽钢连接件将桁架的桁架片通过通长螺栓连接于一体，钢桥为多排、多层或者多排多层的上承式或下承式。
