Abstract
The invention relates to a novel longitudinal through hole, wherein the longitudinal through hole is formed in a rib plate and is arranged in a staggered mode with a reinforcing rib, the longitudinal through hole comprises a longitudinal panel through hole and a longitudinal web through hole, the inner end of the longitudinal web through hole is vertically communicated with the middle of the longitudinal panel through hole, the bottom edge of one side or two sides of the middle of the longitudinal panel through hole, which is close to the longitudinal web through hole, is an outward-protruding arc-shaped edge, and the arc-shaped edge is connected with the side edge of the longitudinal web through hole through a soft toe end. 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.
Description
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.

Detailed Description
The invention is further illustrated by the following figures and examples.
FIG. 3 shows: the longitudinal through holes are arranged on the rib plates 1 and are staggered with the reinforcing ribs 2.
In the first embodiment shown in fig. 1, the longitudinal through hole comprises a longitudinal panel through hole 3 and a longitudinal web through hole 4, the inner end of the longitudinal web through hole is vertically communicated with the middle part of the longitudinal panel through hole, the hole bottom edge of one side or two sides of the middle part of the longitudinal panel through hole, which is close to the longitudinal web through hole, is an outward convex arc-shaped edge 7, and the arc-shaped edge 7 is connected with the hole side edge of the longitudinal web through hole through a soft toe end 8.
In the second embodiment shown in fig. 2, the second through hole includes a second through hole and a second through hole, one side of the second through hole is punched to form an arc-shaped edge with a soft toe end, the other side of the second through hole is a square opening along the second through hole, a patch 9 is welded on the square opening, and the arc-shaped edge with a patch soft toe end 10 on the patch 9 is buckled on the other side of the second through hole and is structurally symmetrical to one side of the second through hole.
