Abstract

The invention relates to a method for processing and installing a rigid suspender of a pedestrian suspension bridge, belonging to the field of bridge engineering. Both ends of the existing wire rope sling or rigid pull rod sling are provided with anchor heads, the upper end is anchored to the main cable clamp, and the lower end is anchored to the main beam. If the existing technology is applied to short slings with a length of less than 1m, the anchor heads at both ends will take up more than 2 / 3 of the length and cost, and the amount of the cable body itself will be small, so that the manufacturing cycle and production cost of the entire bridge will be greatly reduced. Increase. The processing method of the present invention is used for processing the rigid suspenders of pedestrian suspension bridges, and is characterized in that: the rigid suspenders of pedestrian suspension bridges include flat plates, pin shafts, pin holes and ventilation holes, and the two ends of the flat plates are Each pin hole is provided with a pin shaft installed in each pin hole, the pin shaft penetrates the flat plate, and the ventilation hole is arranged in the middle of the flat plate.

Description

technical field [0001] The invention relates to a method for processing and installing a rigid suspender of a pedestrian suspension bridge, belonging to the field of bridge engineering. Background technique [0002] Suspension bridges are widely used as long-span pedestrian bridges in cities and scenic spots because of their large spanning capacity, beautiful line shape and good economy. Suspension bridge suspenders are also called suspenders, and their function is to transmit dead loads such as stiffening beams and bridge deck live loads to the main cables. Due to the catenary shape of the suspension bridge, the length of each sling is different, and the sling in the mid-span is the shortest, which is generally called a short sling. In long-span vehicular bridges, the minimum length of the sling is generally designed to be 3 to 5 m, considering the fatigue damage caused by the vehicle load to the short sling at the mid-span position. For pedestrian bridges, there is no cl...
