It is known that the concentration of working stresses in ship structures can occur at the intersection points of the girders of the T-beams, these intersections can be sources of cracks, especially if they are located on sections of the hull with increased vibration, while it is advisable to draw cross-shaped intersections with a shaped patch mounted on the belts , in such cases, the intersection of the beams and the shaped overlay is better to pre-assemble in the form of a cross-shaped element, hmilnik.com/books/knisha.t.zhuk

A known knot is the connection set of the hull of the ship's hull, including two intersecting beams, consisting of walls and girdles and connected to the casing by welding, while in the wall of one of the beams made cutouts, RU No. 2031809 C1, B63B 3/14, 03/27/1995.

This technical solution was adopted as the closest analogue of this utility model.

In the closest analogue, on the beams of the main direction, partial open cuts are made in the upper girdle to the walls of these beams at the points of intersection with the beams of the transverse direction, and in the beams of the transverse direction, open cuts are made in the cross section of the walls along the width of the walls of the beams of the main direction and the height of the latter, and the data the cutouts are aligned with the cutouts in the beams of the main direction and are connected by welding along the entire perimeter.

The design of the closest analogue is technologically inefficient. The heights of the profiles of welded intersecting beams of the closest analogue are the same, therefore, where the surface of the skin of the vessel is different from the flat, the surfaces of the belts of the intersecting beams do not coincide, which causes difficulties in ensuring the continuity of the belts of each of the beams in the intersection, and cutting the belt of one of the intersecting beams leads to weakening beam profile.

The present utility model is based on a solution that makes it possible to increase the efficiency of using cross sections of both directions, increase the strength and stability of the joints of intersecting beams, and simplify the assembly technology.

The technical result of this utility model is to ensure continuity of the connection of the belts of each of the beams in the intersection by increasing the profile height of one of the beams compared to the height of the beams of the other direction so that the belt of the first beam passes continuously over the belts of the beams of the other direction and the wall of the first beam has a cut when connected to beams of a different direction, and the belt of the first beam in places of passage above the belts of beams of another direction is separated from its wall, but connected to schyu with brackets with a belt a different direction bars.

According to a utility model, this problem is solved due to the fact that the design of the connection set of the body of the displacement object includes two intersecting beams, consisting of walls and girdles and connected to the skin by welding, while cutouts are made in the wall of one of the beams.

The walls of the beams are located in two intersecting planes, and the bands are located in disjoint surfaces within their width.

The wall of the beam with a cut within the cut is not connected to the girdle and two brackets are installed at the intersection of the beams along the edges of the cut.

The brackets are made in the form of plates in the shape of a quadrangle, the corners of the larger side of which are cropped.

The side of the quadrangle adjacent to the girdle of the intersecting beam has a length no less than its width and is welded to this girdle.

The large side of the quadrangle adjacent to the edge of the girdle of the beam with a notch is welded to the edge of this girdle.

In this case, the other two sides of the quadrangle form with a side adjacent to the girdle of the intersecting beam, the angles are no less than a straight line.

The applicant has not identified sources containing information on technical solutions identical to this utility model, which allows us to conclude that it meets the criterion of "novelty."

The implementation of the wall 2 of the beam 1 with a cut 3, not connected to the girdle 4 within the cut 3, and the installation at the intersection of the beams 1 and 5 along the edges of the cut 3 of two brackets 8 prevent the possible loss of stability of the girdle 4 of the beam 1 and increase the strength of the connection of the intersecting beams 1 and 5.
