Embodiment 3

[0093] The processing method of the rigid suspender of the pedestrian suspension bridge in the present embodiment is used to process the rigid suspender of the pedestrian suspension bridge in embodiment 1 and embodiment 2, and the processing method is as follows:

[0094] 1. The flat plate 1 is processed and formed by a whole steel plate, and is cut and opened by numerical control plasma cutting technology.

[0095] 2. The plate 1 should check the grade, thickness and surface quality of the steel plate before blanking, and the blank can only be blanked after passing the inspection.

[0096] 3. Carry out a comprehensive inspection of the CNC machine tool before operation; check whether the empty car is running normally according to the procedure. Draw the component installation position line, alignment line and inspection line.

[0097] 4. When cutting the edge and opening of the steel plate, first lift the steel plate to the cutting platform and fix it in place, and remove th...

Abstract

The invention relates to a machining and mounting method of a rigid suspender of a pedestrian suspension bridge, and belongs to the field of bridge engineering. Anchor heads are arranged at the two ends of an existing steel wire rope sling or rigid pull rod sling, the upper end is anchored to a main cable clamp, and the lower end is anchored to a main beam. If the prior art is applied to a short sling with the length smaller than 1 m, the anchor heads at the two ends of the short sling occupy more than 2 / 3 of the length and cost, the using amount of the sling body is small, and therefore the manufacturing period and production cost of the whole bridge are greatly prolonged. The machining method is used for machining the rigid suspender of the pedestrian suspension bridge and is characterized in that the rigid suspender of the pedestrian suspension bridge comprises a flat plate, pin shafts, pin holes and a ventilation hole, the two ends of the flat plate are each provided with one pin hole, one pin shaft is installed in each pin hole, the pin shafts penetrate through the flat plate, and the ventilation hole is formed 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...
