Detailed Description

The embodiment of the utility model provides a prestress rope ladder structure, which comprises a stay rope a1, a stay rope b2, a plurality of middle rod pieces 3, two groups of masts 7 and an anchor support rod piece 4 as shown in figures 1-4.

The guy wires a1 and b2 are arranged at intervals, and the two ends of the guy wires a1 and b2 are fixed on the two masts 7 in an up-down staggered way. The relative rotation of the inhaul cable a1 and the inhaul cable b2 is spiral, the inhaul cable a1 and the inhaul cable b2 are supported by a plurality of middle rod pieces 3, the middle rod pieces 3 are distributed at equal intervals along the length direction of the inhaul cable a1 and the length direction of the inhaul cable b2, and the mast 7 is in inclined-pulling fixed connection on the bridge deck structure 5 through the anchor support rod pieces 4.

The width of the rope ladder in the length direction can be equal or unequal. The prestress rope ladder structure is flexible to arrange, and the rope ladder width can be adjusted or rotated by different angles of the inhaul cable a1 and the inhaul cable b2 according to the appearance and the structure stress requirement, so that the better structure form is achieved.

As shown in fig. 1, the plurality of middle rod pieces 3 are equal in length, the rope ladder structure is of equal width as a whole, and the relative rotation angle of the inhaul cable a1 and the inhaul cable b2 is about 180 degrees.
