Scaffold for connecting piles with circular pile legs

Abstract

The invention relates to the ship assembling tool technical field, and specifically relates to a round pile leg pile extension scaffold arranged in the closing portion between two pile legs; the scaffold comprises two semicircle inner clasps enclosing the outer wall of the round pile leg, wherein the two semicircle inner clasps are fixed on a tooth bar plate in the round pile leg closing portion; the scaffold also comprises an outer frame structure arranged on the two semicircle inner clasps; a steel plate is flatted on the outer frame structure, and protection rails are arranged outside the outer frame structure; the outer frame structure can be directly arranged in the closing portion in pile extension construction; the round pile leg pile extension scaffold is simple in making, low in investment, convenient in dismounting, can be repeatedly used, can prevent the conventional mode in which a steel pipe scaffold is erected from ground upward, thus reducing height, and improving safety.

Description

technical field [0001] The invention relates to the technical field of ship assembly tooling, in particular to a scaffold for connecting piles with circular pile legs. Background technique [0002] The self-elevating platform with cylindrical legs usually operates at a water depth of 60-80 meters, and the length of the legs is 80-120 meters. The pile legs are generally constructed in sections, and the length of each section of the pile leg is determined according to the capacity of the lifting equipment of each shipyard and the height of the hoisting height. Usually, it is divided into one section of 20 to 40 meters. Then lengthen each section of pile leg sequentially from bottom to top. When the pile legs are connected to the pile, the closing mouth is welded. If there are ladders and platforms in the pile leg cylinder, a scaffolding construction platform needs to be set up on the outside. Because the hull of the platform has been basically formed when the piles are conne...

AI Technical Summary

Problems solved by technology

Because the hull of the platform has been basically formed when the piles are connected, the external scaffolding of the pile legs is usually set up from the main deck or the top deck or steel structure platform of the open-air area of ​​the pile legs. Too high is less safe

Regardless of the long time required for erection and dismantling, it will affect the platform construction and future lifting tests.
