Description

This invention relates to shipbuilding, in particular, to the manufacture and repair technology of a ship hull.

The purpose of the invention is to increase the productivity of hull work.

FIG. 1 shows the position of sections of the hull structures AB and BC before assembling; in fig. 2 - the first stage of assembly: the reduction in one plane of the ends of the beams and their fastening to the casing; in fig. 3 - the second stage of the assembly: moving the ends of the beams in the plane of their walls before alignment and fixing the edges of the plating on the section AB; in fig. 4 - the third stage of assembly: mixing, fixing and fixing the ends of the beams in height.

The method is carried out as follows.

The prepared section after cutting off the allowance and stripping of the mounting edges is finally installed under the assembly.

By installing and securing a non-welded device in the area of the assembly joint of the first pair of beams, the ends of beams 1 and 2 are aligned and secured between them (Fig. 1). This operation achieves a starting position for the assembly of the skin edges in the areas AB and BC and the joints of beams 3 and 4, 5 and 6.

Then begin the assembly phase of the section AB by installing unsettled

on the joint of beams 3 and 4 (Fig. 2), in one plane of the ends of the beams and fixing them to the casing 7 and 8 with tack 9.

After these operations, the next assembly step is carried out, in which the ends of the beams 3 and 4 are moved in the plane of their walls with the same device until the edges of the casing align over the area EI and fix the reduced points of the casing edges with tacks 10 (Fig. 3).

Due to the further movements of the ends of the beams 3 and 4 by the said device, the edges of the sheathing 7 and 8 of the section AB are successively aligned and secured with tacks (Fig. 4).

At the final stage of assembly of section AB, the ends of beams 3 and 4 are finally aligned in height and secured by tacking 11 (Fig. 4).

The aircraft trim section and the beams 5 and 6 of the kit are joined and fixed in the same way as the assembly steps indicated.

The use of the proposed method allows to reduce the laboriousness of the assembly by eliminating the need to use temporary welded elements (dies, brackets, butts, etc.) when joining the edges of the cladding sheets; simultaneous execution of the operations of assembling the butt joints and the beams of the set on one side of the hull structure.

METHOD FOR ASSEMBLING SHIPBOARD HULL STRUCTURES, including flattening and securing the ends of the set beams to the skin, as well as the ends of the set beams and the edges of the skin of the sections to be joined together, characterized in that, in order to increase the performance of the hull work, the ends of the set beams connected after bringing them into one plane and fixing to the casing are moved relative to each other in the plane of the walls until they are subsequently aligned and fixed at individual points on the edges of the sheets of the casing of the mating sections for spations.
