Abstract

The invention discloses a method for erecting scaffold handrails for the top of a hatch coaming. The method comprises the following steps: setting installation positions of scaffold handrails according to operation conditions in ship construction; designing fixtures according to a structure size of the top of the hatch coaming; fixing the fixtures to a rabbet and a hanging keel of the hatch coaming; inserting handrail columns in the fixtures; and erecting the scaffold handrails. The method for erecting scaffold handrails for the top of a hatch coaming is capable of erecting scaffold handrails conveniently and rapidly without damaging the steel parent metal; and the operation safety of the aloft construction personnel can be protected.

Description

technical field [0001] The invention relates to a method for erecting a scaffold railing, in particular to a method for erecting a scaffold rail for the top of a hatch coaming. Background technique [0002] Usually, in ship construction, scaffolding railings need to be set up for high-altitude operations to ensure the safety of construction personnel. The commonly used method of erecting scaffolding railings is to use assembled tooling parts for erection. There are two specific methods as follows: [0003] 1. The collet-type railing column is matched with the edge of the structure. In this method, the chuck-type railing column is clamped at the edge of the structure, and then the scaffolding railing is erected by using the railing column. This method is convenient and fast, but for the hatch coaming area of ​​special materials, taking E47 steel as an example, figure 1 and figure 2 It shows that there is a circular chamfer R of 2~5mm on the edge of the top plate of the ha...
