Description

Technical Field

[0001] The utility model relates to the technical field of ladders, in particular to a ladder bracket installed on a pipe pile. Background Art

[0002] The ladder bracket on the traditional pipe pile is often fixed by welding. During installation, the ladder is hoisted as a whole to one side of the steel pipe pile and welded to the outer wall of the steel pipe pile. This method requires construction workers to weld the ladder at high altitude, which poses a great risk. In addition, when the ladder needs to be dismantled, it needs to be cut off, which will cause serious damage to the wall of the steel pipe pile and affect its reuse.

[0003] In view of the above problems, a clamp-type installation structure of a steel pipe pile support safety ladder disclosed in publication number CN213391958U has the disadvantage that the two ladder beams of the ladder are respectively welded to each clamp through a connecting plate, which makes it difficult to adjust the circumferential position of the ladder and the clamp.
