AI Technical Summary

Technical Problem

Existing welded anchoring points in shipbuilding suffer from high costs, long construction periods, low efficiency, significant safety hazards, and serious material waste, and do not meet the aesthetic requirements of ships.

Method used

A non-welded anchoring and fixing device adapted to the protruding structure of the hull plating is adopted, including a connecting plate and a limiting plate. It is connected to the protruding structure of the hull plating by hook grooves and through holes. Scaffolding steel pipes are erected and fixed firmly to avoid high-altitude welding operations and achieve reusability.

Benefits of technology

It achieves simple, short-cycle, safe, and damage-free scaffolding erection and dismantling, improving construction efficiency and safety, and ensuring the aesthetics of the ship's outer plating.

Abstract

This invention discloses a non-welded anchoring and fixing method for segmented outer plate scaffolding, applying an anchoring and fixing device adapted to the protruding structure of the ship's outer plate. The method includes the following steps: First, design and manufacture the anchoring and fixing device according to the protruding structure of the pre-erected area's outer plate; second, install the anchoring and fixing device in advance according to scaffolding erection standards; third, erect the scaffolding working platform using the anchoring and fixing device; fourth, after the painting work is completed, dismantle the scaffolding working platform according to the scaffolding steel pipe erection and dismantling sequence, and recycle and reuse the anchoring and fixing device; finally, quickly complete the painting work in the reserved area according to the painting repair requirements. This invention utilizes the anchoring and fixing device for scaffolding erection, which is simple to erect and dismantle, eliminates high-altitude welding, cutting, and dismantling operations, shortens the construction cycle, increases safety, and improves construction efficiency; simultaneously, it ensures zero damage to the ship's outer plate surface, enhancing the overall aesthetics.
