Ship wall door and window hole machining method and door and window hole shape maintaining tool

Abstract

The invention relates to the technical field of shipbuilding, and discloses a ship wall door and window hole machining method and a door and window hole machining hole shape maintaining tool. The shipwall door and window hole machining method comprises the steps of forming a door and window hole in the preset door hole machining position of a wallboard blank to form a wallboard; welding studs tothe periphery of the exterior of the door and window hole of the wallboard at intervals; detachably connecting a reinforcing rib set to the wallboard through the studs, and enabling the reinforcing rib to surround the door and window hole to form a frame structure; carrying out assembly segmentation on a plurality of wallboards, and then carrying out block assembling; and disassembling the reinforcing rib set and the studs on the wallboards. The door and window hole machined through the ship wall door and window hole machining method is small in deformation, and the damage to base metal is small. The door and window hole shape maintaining tool is easy and convenient to operate through the ship wall door and window hole machining method, and the deformation generated in the assembly segmentation process and the block assembling after door and window hole machining can be reduced.

Description

[0001] The invention relates to the technical field of shipbuilding, in particular to a method for processing door and window holes on a ship wall and shape-preserving tooling for the door and window holes. Background technique [0002] Large-scale ships include ro-ro passenger ships, etc., and the ship wall is composed of multiple panels. When building a ship, it is necessary to cut multiple panels in sections first, and then assemble the segmented panels. For the wall panels that need to process holes for installing doors and windows, due to the large size of the doors and windows, and the thin wall panels, it is easy to cause deformation to varying degrees during the entire construction process, which will affect the installation of subsequent door and window holes. [0003] In the prior art, the following three methods are usually used for processing door and window holes on wall panels: 1. figure 1 As shown in (a) (the shaded part in the figure represents the cut-off part...

For the wall panels that need to process the holes for installing doors and windows, due to the large size of the doors and windows, and the thin wall panels, it is easy to cause deformation to varying degrees during the entire construction process, which will affect the installation of subsequent door and window holes

[0003] In the prior art, the following three methods are usually used for processing door and window holes on wall panels: 1. figure 1 As shown in (a) (the shaded part in the figure represents the cut-off part), in the segmental blanking stage of the wall panel, the door and window holes are not opened at the preset door and window hole processing position 11' of the wall panel blank 1'. Maintaining the shape of the hole position and controlling the straightness of the wall panel have a certain effect, but opening the door and window holes after the general assembly requires manual marking and cutting of the holes on the one hand, resulting in poor quality and low precision of the holes; on the other hand, Failure to open the door and window holes will cause inconvenience for the construction personnel to walk and affect the construction progress

Two, such as figure 1 As shown in (b), in the segmental blanking stage of the wall panel, only some door and window holes are opened at the preset door and window hole processing position 11' of the wall panel blank 1'. This method can alleviate certain opening deformation in the general assembly stage. However, the edge of the opened position is still easy to cause deformation, and the position where the door and window holes are not opened will also hinder the construction of the general assembly. In addition, the remaining parts need to be cut by hand, and the accuracy is relatively poor.

Three, such as figure 1 As shown in (c), the door and window holes are fully opened in the segmental blanking stage, and the plasma cutting machine is used to blank the material in the segmental stage, with high precision. At this time, a lot of pyrotechnic work is required to correct the deformation of the door hole position with pyrotechnics, which will consume a lot of manpower and material resources. A large amount of pyrotechnic work will easily cause excessive pyrotechnic damage at the joints of the segmented wall panels. Need to change board
