Double-layer curve triangular truss girder structure
The invention relates to a double-layer curve triangular truss girder structure. The double-layer curve triangular truss girder structure comprises an upper-layer cross beam, a lower-layer cross beam opposite to the upper-layer cross beam, upper chords arranged on the two sides of the upper-layer cross beam, lower chords arranged on the two sides of the lower-layer cross beam and inclined rods. An upper layer gusset plate is connected between any two adjacent upper chords; a lower-layer gusset plate is connected between any two adjacent lower chords; an inclined rod is connected between the upper-layer gusset plate and the lower-layer gusset plate, so that the upper chord, the lower chord and the inclined rod are connected into a whole to form a triangular truss; the lower-layer gusset plate is a bent gusset plate, and the upper chord member corresponding to the lower-layer gusset plate in the vertical direction is a bent chord member. According to the double-layer curve triangular truss girder structure, the lower-layer gusset plate is a bent gusset plate, the corresponding upper chord member is a bent chord member, and the curve function of a double-layer bridge floor is achieved; the upper chords, the lower chords and the inclined rods form a stable triangular truss structure, the vertical face of the whole bridge is not provided with vertical rods and only provided with the inclined rods, stability is good, and the steel consumption is small.
本申请涉及一种双层曲线三角桁梁结构，包括上层横梁、与上层横梁相对设置的下层横梁、设于上层横梁两侧的上弦杆、设于下层横梁两侧的下弦杆、斜杆；任意两相邻的上弦杆之间连接有上层节点板；任意两相邻的下弦杆之间连接有下层节点板；上层节点板与下层节点板之间连接有斜杆，使得上弦杆、下弦杆、斜杆连接为一体以形成三角桁架；下层节点板为弯折节点板，与下层节点板沿竖直方向对应的上弦杆为弯折弦杆。本发明提供一种双层曲线三角桁梁结构，下层节点板为弯折节点板，对应的上弦杆为弯折弦杆，实现了双层桥面的曲线功能；上弦杆、下弦杆、斜杆形成了稳定的三角桁架结构，整个桥梁立面没有竖杆，只有斜杆，稳定性好、用钢量小。
