Technical Field

The invention relates to a ship building device, in particular to a novel longitudinal through hole.

Background

With the continuous development and progress of the ship industry, the ships are also developing to be large-scale, and the requirements on the structural strength are higher and higher in a high-stress area. Because the fatigue stress borne by the through hole area is very large, the stress can not be very high eliminated according to the conventional through hole form, and the reinforcing rib needs to be installed with the longitudinal rib, the field construction difficulty is relatively large and complicated, the error rework rate is high, the production period is prolonged, and the shipbuilding cost is correspondingly increased.

Disclosure of Invention

The invention provides a longitudinal through hole with high fatigue resistance.

The technical scheme adopted by the invention is as follows: a novel longitudinal through hole is characterized in that: the longitudinal through holes are arranged on the rib plates in a staggered mode and comprise longitudinal panel through holes and longitudinal web through holes, the inner ends of the longitudinal web through holes are vertically communicated with the middle parts of the longitudinal panel through holes, the hole bottom edges, close to the longitudinal web through holes, of one side or two sides of the middle parts of the longitudinal panel through holes are convex arc-shaped edges, and the arc-shaped edges are connected with the hole side edges of the longitudinal web through holes through soft toe ends.

The soft toe end is a straight section or a circular arc section.

The longitudinal bone panel through hole is formed by punching as a whole, or one side of the longitudinal bone panel through hole is punched to be an arc edge with a soft toe end, the other side of the longitudinal bone panel through hole is a square opening along the longitudinal bone web plate through hole direction, and the welding patch plate on the square opening is in a symmetrical shape with the arc edge structure with one side with the soft toe end.

The invention improves the straight corner structure of the bottom edge of the traditional hole into an outward convex arc edge with a soft toe end, the soft toe height is proper to ensure smooth transition from a welding seam to an arc part, the soft toe end can effectively avoid stress concentration at the position of a transverse strong frame caused by shearing load and local load conducted through a welding joint, the fatigue resistance strength is greatly improved, the reinforcing rib on the perforated rib plate does not need to be arranged on a longitudinal rib plate for reinforcing ribs, the site construction precision is greatly improved, the error rework rate is reduced, the production period is shortened, and the manufacturing cost is reduced. The through hole form is suitable for all large bulk cargo ships, ore sand ships and the like.
