Abstract

PURPOSE:To provide a plate joining method for shortening a term of work and reducing a cost of construction by eliminating necessity for joining a floor by butt welding and filling work of a cut in a floor joining part. CONSTITUTION:In a structure formed of a ship bottom shell plate 1, inner bottom plate 2 and a floor 5, a plate joining position is set to a position where a ship bottom longitudinal 3 and an inner bottom longitudinal 4 are opposed in a vertical direction between the ship bottom shell plate 1 and the inner bottom plate 2. Further, scallop cut parts 7 for use of the inner bottom longitudinal 4 and the ship bottom longitudinal 3 are provided in upper/lower ends of a joining part 8 of the one floor 5, the floor 5 is vertically provided between the ship bottom shell plate 1 and the inner bottom plate 2, a backing steel plate 6 is brought into contact orthogonal to the joining part 8 of the floor 5 between the ship bottom longitudinal 3 and the inner bottom longitudinal 4, and the joining part 8 of the one floor 5 is welded to come into contact with a joining part 10 of the other floor 9 by interposing the backing steel plate 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a steel ship, and more particularly to a method for joining plates such as an inner bottom plate and a ship bottom outer plate at the time of construction.

[0002]

2. Description of the Related Art Conventionally, in a plate joining method according to a method of constructing a steel ship of this type, as shown in FIG. 4, a rib plate 25 welded between a ship bottom outer plate 21 and an inner bottom plate 22 is formed. The plate joint 27 is
The scallop notch 26 is provided in each of the ship bottom stringer 23 and the inner bottom plate stringer 24, and the ribs 25
It is known that scallop cutouts 28 are provided at the upper and lower ends of the plate joint 27, and the ribs 25 and 29 are butt welded to each other for plate joining.

[0003]

According to the prior art, the joints of the ribs need to be butt-welded, and both end faces of the ribs to be jointed must be accurately butted. There is a problem in that it is necessary to fill the scallop notch in the joint of the ribs after welding, which causes a long process and a rise in processing cost.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a joint of ribs by butt welding and a notch in a joint of the ribs. It is an object of the present invention to provide a plate joining method that shortens the construction period and reduces the construction cost by eliminating the work of filling the space.

[0005]

In order to achieve the above object, a plate joining method for a steel ship according to the present invention is such that a plate joining position of an inner bottom plate and a ship bottom outer plate is set between an inner bottom plate and a ship bottom outer plate. , The position where the inner bottom plate stringer and the ship bottom stringer face each other in the vertical direction,
Providing scallop cutouts for the inner bottom plate vertical threading and the ship bottom vertical threading at the upper and lower ends of the plate joining section of one of the ribs to be plate spliced,
The rib plate is erected between the outer plate of the ship bottom and the inner plate of the bottom of the ship, and the flat bar for abutting is orthogonal to the joint of the rib plate between the vertical stringer of the ship bottom and the vertical stringer of the inner bottom plate. And the plate joints of the other ribs and the plate joints of the one rib are joined and welded with the flat steel for abutment interposed.

[0006]

[Function] Between the outer bottom plate and the inner bottom plate, the joints of the ribs at the positions where the vertical and inner bottom stringers vertically oppose each other are the vertical and inner bottom stringers. The scalloped notch of (1) includes the scalloped notch of the plate joint.

[0007]

EXAMPLES Examples will be described with reference to the drawings.
As shown in FIG. 1, in a structure formed by a bottom outer plate 1, an inner bottom plate 2, and a rib 5, a plate joint 8 is located between the bottom outer plate 1 and the inner bottom plate 2 in the longitudinal direction of the bottom of the ship. For the inner bottom plate vertical stringer 4 and the ship bottom vertical stringer 3 at the upper and lower ends of the plate joint 8 of one of the ribs 5 to be plate-spliced at the position where the material 3 and the inner bottom plate vertical stringer 4 face each other in the vertical direction The scallop notch 7 is provided and the rib 5 is attached to the bottom plate 1 of the ship.
And the inner bottom plate 2 are erected.

A rib board 5 is provided between the ship bottom stringer 3 and the inner bottom plate stringer 4.
The flat bar 6 for abutting is abutted orthogonally to the plate joint 8 and the flat plate 10 for abutting the plate joint 10 of the other rib 9 and the plate joint 10 of the one rib 9 to be plate jointed. 6 is interposed and abutted and welded.

[0009]

Since the present invention is configured as described above, it has the following effects. Since it is not necessary to butt weld the joints of the ribs and the flat steel for abutment is interposed between the ribs to be jointed, strength does not deteriorate even if misalignment occurs on both end faces of the joints. Further, the work of filling the scallop notch in the plate joint of the rib after butt welding is not required, and the construction period is shortened and the construction cost is greatly reduced.
