Description

I

The invention relates to shipbuilding and concerns the construction of bottom overlaps of ship hulls.

Known flat overlap of the bottom of the hull with a transverse system of the set of outer skin, in which the area of the cheekbones supported by flora and stiffening ribs, continuing idle frames of the side {1).

However, this overlap is not strong enough and has low manufacturability due to manual. fits the curved profile of the stiffener to the zygomatic outer skin sheet.

Closest to the present invention is a flat overlap of the bottom of the hull of the vessel, which contains a casing with attached kilksons, floras, beam beams frame and idle set and zygomatic knits connected to the frames of the ship hull and the aforementioned beams of the transverse set (2).

However, in this overlap the zygomatic, the brackets are not reliable reinforcement.

the zygomatic sections of the skin are weak because of their fastening on the weak beams of the idle set, the knot attachment to the beams is weak, and the presence of the poultry pork curds in the cheek knives also reduces their stability under the action of concentrated forces.

The purpose of the invention is to increase the durability and reliability of the overlap.

This goal is achieved by the fact that the overlap is made with longitudinal zygomatic beams 10, the wall height of which is 2 to 2.5 times the height of the wall of the beams of the transverse idle set, and the walls of the above zygomatic beams are located between the ends of the brackets and the beams of the transverse idle set.

In addition, with such an overlap, the longitudinal zygomatic beams are advisable to perform with blueberries, which can be located in the spans between the edental cheeks.

FIG. Figure 1 shows schematically the planar overlap of the bottom of the hull of the ship, an axonometric display: in FIG. 2 - the same. 390 cross section; in fig. 3 shows section A-A in FIG. 2. On the casing 1 are fixed beams 2 of the transverse idling set, knives 3, flora 4 and cheekbone brackets 5, connected to the side of the board 6. With the ends of the beams 2 and knits 5, the longitudinal zygomatic beams 7 installed in this zone are connected with 8 pancakes made in them in spans between knitsdmi 5. Above the top of the beams 7 there is a free juice 9 located on the side facing the center plane of the vessel. Beams 2 are additionally fastened with beams 7 knitsaksh 10. Flora 4 are connected with beams 11 of the transverse frame set. The height of Balkn 7 is 2-2.5 times the height of Beam 2 and is determined by the need to securely fix the ends of the beams 2 knits Yu, having a viewpoint not less than the height of the beams 2, as well as the span length of the beam 7 (the distance between floras) and the need to ensure normal access to perform welds connecting the knots 5 to the beam 7. When landing a vessel on the ground, the force of interaction is perceived by the sheathing 1, 1 15, which load the frames 6 and the beam 7. The latter transfers the load on the flora 4 and the beams 11. Beams 7 allow to increase the strength of the cross ti due to more reliably secure the brackets 5 and povpieni stiffness due to reducing the skin -size unsubstantiated its sections (plates). Beams 7, it is advisable to have as far as possible on the greater length of the hull, and the thickness of their walls to be equal to the thickness of the bottom 1 of the hull. The technical and economic effect of the implementation of the proposed invention is that the strength of the bottom in the cheek area is both

Claims (2)

# 4 is redistributed by concentrated loads in the event of a ship being stranded on its frame set by means of longitudinal zygomatic beams. Claims 1. Flat bottom floor of the ship hull. containing them on the keelsons, floras, beams of the transverse frame and idle set and cheeky knits connected to the frames of the hull side of the vessel with the above mentioned beams across the set, characterized in that longitudinal zygomatic beams) the wall height of which is 2-2.5 times the height of the wall of the beams of the transverse idle set, and the walls of the above zygomatic beams are located between the ends of the knitting and beams of the cross holo full set. 2. The overlap of claim. 1, characterized in that the longitudinal zygomatic beams are made with poultry poultry, which are located in the spans between these zygomatic knits.
