Large-span fabricated cable truss structure for channel covering
The invention discloses a large-span fabricated cable truss structure for channel covering. The structure is characterized in that upper chord section steel (2) is positioned above two lower chord steel inhaul cables (3), and a horizontal steel web member (5) is arranged between the two lower chord steel inhaul cables (3); and a herringbone steel web member (4) is arranged between the single arc-shaped upper chord section steel (2) and the two lower chord steel inhaul cables (3), and a triangle is defined by the upper chord section steel (2), the lower chord steel inhaul cables (3), the herringbone steel web member (4) and the horizontal steel web member (5). The problems that in the prior art, a steel structure platform is arranged in a water conveying channel, the channel span is large, supporting is difficult, and installation is not easy are solved, and the structure has the advantages that the triangle is defined by the upper chord section steel, the herringbone steel web member and the horizontal steel web member, a stable self-balancing system is achieved, and overall stress is reasonable.
本发明公布了一种用于渠道遮盖的大跨度装配式索桁架结构，所述的上弦型钢(2)位于两根所述的下弦钢拉索(3)上方,两根所述的下弦钢拉索(3)之间设置有水平钢腹杆(5)；单根呈圆弧形的所述的上弦型钢(2)与两根所述的下弦钢拉索(3)之间设置有呈人字形钢腹杆(4)，所述的上弦型钢(2)、下弦钢拉索(3)、人字形钢腹杆(4)与水平钢腹杆(5)之间围成三角形，它克服了现有技术输水渠道内设置钢结构平台面临的渠道跨度大、支撑难、不易安装的问题，具有上弦型钢、人字形钢腹杆与水平钢腹杆之间围成三角形，达到一种稳定的自平衡体系，整体受力合理的优点。
