Description

Technical Field

[0001] The utility model relates to the technical field of cable clamps, in particular to a wind-resistant main cable clamp for a pedestrian suspension bridge. Background Art

[0002] Pedestrian suspension bridges, characterized by their strong span capacity, elegant lines, and ease of construction, have become the primary form of long-span bridge construction in recent years, particularly in scenic areas and mountainous areas like canyons. Pedestrian suspension bridges also have the characteristics of large spans, narrow decks, and low beam stiffness. Wind loads often cause the structure to torsion or lateral instability, making wind resistance a major design challenge for these structures.

[0003] The existing main cable clamp lacks a supporting structure nearby and is easily loosened under the action of wind, causing the clamp to deform or be damaged, which will eventually pose a safety hazard to the pedestrian suspension bridge. Therefore, a wind-resistant main cable clamp for a pedestrian suspension bridge is proposed.

[0004] A wind-resistant main cable clamp for a pedestrian suspension bridge disclosed in announcement number CN216973120U can effectively solve the problem of slippage of the wind-resistant cable on the wind-resistant main cable, thereby improving the working efficiency of the wind-resistant cable and the wind-resistant performance of the pedestrian suspension bridge. The utility model comprises an upper splint, a lower splint, a U-shaped bolt, a nut and a limiting ring; the upper splint and the lower splint are symmetrically arranged in the upper and lower parts, and the upper splint is located above the lower splint; an upper splint groove is provided on the bottom surface of the upper splint, and a lower splint groove is provided on the top surface of the lower splint, and the upper splint groove and the lower splint groove enclose a space for clamping the wind-resistant main cable; an upper splint bolt hole is provided on the upper splint, and a lower splint bolt hole is provided on the lower splint; the limiting ring is fixedly provided at the tail end of the arc segment of the U-shaped bolt; the straight section of the U-shaped bolt passes through the upper splint bolt hole and the lower splint bolt hole, the nut is threadedly connected and tightened with the straight section, and the nut and the limiting ring clamp the upper splint and the lower splint in the middle and tighten them.

[0005] Although the above patent has achieved the goal of increasing the friction between the wind-resistant cable and the main cable by increasing the contact area, thereby improving the anti-slip ability of the wind-resistant cable on the wind-resistant main cable, and better fixing the wind-resistant cable at the specified design position of the wind-resistant main cable, ensuring that the wind-resistant cable system can work according to the specified design line, improving the working efficiency of the wind-resistant cable and the wind-resistant performance of the pedestrian suspension bridge; however, the device lacks the function of adjusting the height and angle between the two cable clamps.
