Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0025] Such as image 3 As shown, the auxiliary structure for ship block construction of the preferred embodiment of the present invention includes ship ribs and ship longitudinals 3, which include a plurality of false ship ribs 1, and a plurality of false ship ribs 1 are overlapped in sequence An inverted triangular fake ship rib frame 2 is formed, and the fake ship rib 1 is provided with positioning holes 11 through which corresponding ship longitudinals pass.

The invention discloses an auxiliary structure for ship block construction and a manufacturing method thereof, which comprises a plurality of fake ship ribs, and is mainly used to pass materials through the neutral rib positions on the ship body according to the line shape of the ship ribs. Carry out lofting and blanking, and form a plurality of fake ship ribs with the function of ship ribs at the neutral rib position, and the plurality of fake ship ribs are respectively along the main deck line, left and right sides of the neutral rib position of the ship body. The outer plate line and the right outer plate line are sequentially built to form an inverted triangle fake ship rib frame. The auxiliary structure in the present invention is mainly applied in the segmental reverse-building process of the ship body. When the ship body is reversed in segments, the position of the neutral rib or the distance between the ribs of the ship is relatively large, so that the positioning of some longitudinal frames of the ship is inaccurate. At this time The auxiliary structure not only ensures the positioning of the ship's longitudinal beam, but also strengthens the strength at the neutral rib, thereby ensuring the segmented line shape of the ship body and the construction accuracy of the ship.
Description
technical field [0001] The invention relates to the technical field of ship block building, in particular to an auxiliary structure for ship block building and a manufacturing method thereof. Background technique [0002] At present, the block construction methods of ships are generally divided into positive building with the outer plate as the upper plate or reverse with the deck, platform plate and wall plate as the upper plate. The orthographic tire frame can ensure the segmented line type, while the reverse construction mainly relies on the ship's ribs and ship longitudinal frame to ensure the segmented line type. When the frame spacing of the ship is too large or there is a gap in the rib position, the segmented reverse fabrication method, the ship ribs and the ship longitudinal frame are not enough to ensure the segmented line shape. Moreover, the ship longitudinals at the neutral ribs cannot be positioned accurately, which seriously affects the accuracy of segmented ...
