Method for building scaffolds in closing stage of bottom side tank of bulk cargo ship cargo hold

Abstract

The invention discloses a method for building scaffolds in the closing stage of a bottom side tank of a bulk cargo ship cargo hold. Closing seams of the closing stage of the bottom side tank include ballast tank internal closing seams and bevel board closing seams. The three kinds of scaffolds are included according to the different scaffold building positions. According to the method, the tool type scaffolds are mainly adopted to meet the construction demand of the closing seams of the ship bottom side tank in the closing stage, and the prior mode with a lot of steel tube scaffolds adopted is replaced. Scaffold pore plates can be preassembled in the block stage, and part of the scaffold pore plates can be used both in the block stage and the header stage, so that the utilization rate of scaffold tools is increased.

Description

technical field [0001] The invention relates to a method for building scaffolding for a ship, in particular to a method for building a scaffold for closing joints of a cargo tank hopper tank of a bulk carrier in the large closing stage, and belongs to the technical field of ship engineering equipment. Background technique [0002] With the continuous development of shipbuilding technology, shipbuilding enterprises are increasingly pursuing the integration of shell, outfitting and coating and CIMS shipbuilding methods. Shipbuilding has the characteristics of three-dimensional cross operation, and the painting and construction of ships need to borrow scaffolding. In the process of traditional ship construction, scaffolding steel pipes are often connected with shackles to form a spatial geometric three-dimensional structure. For the construction of this kind of scaffolding, shipyards basically adopt on-site operation methods such as workers to determine the position on site an...

Problems solved by technology

This form of scaffolding uses more materials, and it is time-consuming and labor-intensive to build and disassemble. At the same time, it will cause damage to the paint of the ship, which is not conducive to the protection of PSPC.

Taking the big closing stage of a large bulk carrier as an example, the use of steel pipe scaffolding for the large closing joints in the ballast tank during the large closing construction of the berth / dock stage will cause relatively large damage to the paint. If the steel pipe scaffolding is used at the closing seam of the mouth, the interior of the cargo hold will be full of scaffolding, so whether it is erected or disassembled, it will have a certain impact on the construction period of the ship.
