The free ends of the corresponding horizontal girders 3 are open. In this case, the space of the head part is very narrow, and if the conventional welding form is adopted between the outer plate and the horizontal structure, the welding quality cannot be guaranteed.

Therefore, a new bow outer plate structure is required.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a ship bow planking structure, the utility model discloses a liner welds the welding quality of dead capsule structure, assurance prelude planking for need not the welding between inner structure and the planking, it is narrow and small to avoid the space, guarantees welding quality.

The utility model aims at realizing through the following technical scheme that a bow outer plate structure comprises a stem and an outer plate, wherein a plurality of horizontal trusses are arranged on the outer plate from top to bottom, and the bow outer plate structure is characterized in that a rib plate is arranged on the free end of each horizontal truss, and the rib plate, the stem and the outer plate are enclosed to form a sealed cabin;

the planking includes a plurality of planking subassembly that top-down set up, sets up horizontal purlin between two adjacent planking subassemblies, and welded connection between two adjacent planking subassemblies, the horizontal purlin three that corresponds.

Preferably, the two adjacent outer plate assemblies and the corresponding horizontal girders are connected by adopting plunger welding.

Preferably, the thickness of the horizontal girder is 20-40 mm.

Preferably, the spacing between adjacent horizontal girders is less than or equal to 500 mm.

Preferably, the rib plate is connected with the free end of the horizontal truss in a welding mode.

Preferably, the welding ends of the outer plate components are grooves, the angle of each groove is 45-55 degrees, and the distance between the welding ends of the adjacent outer plate components is 5-8 mm.

Compared with the prior art, the utility model discloses following beneficial effect has:

first, the utility model discloses need to seal up the cabin to the unable welded narrow and small space in bow, make the planking subassembly with the planking, adopt plug welding form lid planking at last, utilize the thickness of horizontal purlin as the liner, guarantee welding quality.

And secondly, the utility model discloses increase horizontal purlin thickness to 20-40mm for between horizontal purlin and two shrouding subassemblies that correspond, sufficient area of contact and intensity have, further guarantee the plug welding quality.

Third, the utility model discloses with the welding of current narrow and small space in the bow convert into at the outer welding of bow, the operation of being convenient for further guarantees welding quality.
