Foot plank mounting structure and design method thereof and foot plank changing method

Abstract

The invention provides a foot plank mounting structure and a design method thereof. The foot plank mounting structure comprises clamping grooves and foot planks, wherein the clamping grooves are mounted on the left and right sides of a foot plank support in the walking direction, and the foot planks are mounted between the two clamping grooves and arranged close to each other in sequence in the walking direction; the foot plank mounting structure is characterized in that the left and right ends of the foot plank are correspondingly in slippage fit with the clamping grooves and extend into theclamping grooves; the foot planks at the front and rear ends of the clamping grooves are in locating fit with the clamping grooves in a detachable manner; openings used for taking out the foot planksfrom the clamping grooves are formed in the clamping grooves; and the parts, at the openings, of the foot planks are fixed to the clamping grooves through bolts. According to the foot plank mounting structure and the design method thereof, the movements of the foot planks in the walking direction are effectively limited, the locating of the foot planks is more convenient, the locating reliabilityis better, the overhauling and changing of the foot planks are made convenient, damage to the foot plank mounting structure caused by changing the foot planks is avoided, the structural stability of the foot plank mounting is better, and the practicability is higher. The invention further provides a foot plank changing method.

Description

technical field [0001] The invention relates to a walking slab installation structure and a design method thereof, which are used for installing the walking slab on a railway bridge. The invention also relates to a walking board replacement method. Background technique [0002] Existing concrete walking slabs are installed in a single span, and the weight of a square meter concrete walking slab is generally more than 100 kilograms, which is very inconvenient for high-altitude operations on both sides of the railway bridge, so the walking slab is easily caused to fall off during the installation process. In addition, the distance between the brackets installed on site has a large error, which leads to insufficient lap length of the ends of the walking board, causing the walking board to fall off. Moreover, the walking board is installed in the F-shaped card slot, but in actual use, the displacement of the walking board along the extending direction of the card slot cannot be...
