Crash resistant construction with double hull

 

The invention relates to shipbuilding and construction, in particular to design the ship with double hull. Crash resistant construction with double hull has an external cladding and internal lining. The design contains a number of channels, made of plastic material and located next to or above each other. Channels attached to the edges of their side walls to the inner surface of the outer casing. The base of each channel is connected to at least a stringer, essentially perpendicular to the bottom, to the inner hull or structure attached to the latter. The Foundation of the serial channels can be connected to each other by means of strips or stringers. The side walls of the channel directed toward the inner surface of the outer casing may be formed with the outer casing angleless than 90. The channels can be formed on the inner surface of the inner shell. These channels can be attached edges of the side walls to the inner surface. The stringers may extend between the channels formed on the outer skin, and channels formed on the interior of the casing a result of implementation of the invention is to improve stability of the structure with a double hull to impact and explosion. 5 C.p. f-crystals, 5 Il.

The invention relates to a crash resistant construction with double hull type of the ship with double outer skin.

If oil tankers collide or get stranded, then the formation of the hull holes it can lead to serious environmental pollution. The same applies to tankers for transportation of chemicals on the inland waterways. Existing transportation craft are at risk of formation of holes in the side in the event of a collision, which in some circumstances leads to a significant risk to the safety of passengers. Thus it is obvious that it is extremely important to increase resistance to shock and blast designs with double hull ships, coastal equipment and facilities for the manufacturing industry.

The task of the invention to provide improved substantially resistant to impact and blast design with double hull. In accordance with the invention, this design contains a number of channels, made of plastic material and arranged side by side or one above the other, and these channels are attached by their edges makinano at least a stringer, essentially perpendicular to the bottom, to the inner hull structure or building attached to it.

Substantially increased resistance to the formation of holes is achieved by the fact that in the event of a collision appears dent, of considerable width, is ideal membrane voltage and the maximum resistance to the formation of holes.

An even better result is achieved if the Foundation of the serial channels are connected to each other by means of strips or stringers. Strip or stringer provide a symmetrical deformation of the both side walls of the channels at the beginning of the collision. Then strip or stringer breaks off. If strip or stringer absent, then the collision, there is a risk that one of the side walls of the channels sags, essentially in one direction and the other side wall follows the first side wall. This asymmetrical displacement of the side walls of the channels leads to a decrease in resistance to the formation of holes.

The idea is that part of the channel or the side walls, which are directed to the inner surface of the exterior side of the vehicle, formed with the outer casing angleless is inate with each other for the formation of a single corrugated plate.

In the case of concrete structures, channels also feature on the inner surface of the inner casing, and these channels are attached edges of the side walls to the inner surface, and the stringers extend between the channels located on the outer skin, and the channels located on the inside lining.

The construction material should be plastic steel 37, which has proven itself as an excellent material, but also can handle some plastics and materials that have a so-called trajectory destruction of some type of composite and multi-layer materials.

Below the invention is explained on the basis of the description of the drawings.

Fig.1 depicts a perspective view of part of the ship with double hull according to the first variant embodiment of the invention.

Fig.2 depicts the vertical section of the ship corresponding to Fig.1.

Fig.3 depicts the vertical section of the ship corresponding to Fig.1, after heavy clashes.

Fig.4 depicts a vertical section of a second variant implementation of the ship.

Fig.5 depicts a vertical section of a third variant of the implementation of the ship.

Design with double clapboard the inner surface of the outer casing 1. The channels have two side walls 4, 5 which form an angle equal to 45with the outer casing 1 and the base 6, which connects the two side walls 4 and 5 to each other. Stringer 7 extends from the base 6 channels perpendicular to the base to the inner surface of the inner shell 2. Reason 6 serial channels are connected to each other by strips 8. Material parts 1-8 plastic and consists, for example, of steel 37.

In Fig.3 shows a case where the corresponding Fig.1 and 2, the section of the ship with double hull subjected to a severe collision. The outer casing 1 has shifted slightly inward and the side walls 4 and 5 of the channel bent. Stringer 7 was curved. During the collision the holes are not formed. In fact, it is a question of the membrane voltage.

In the embodiment according to Fig.4 channels are semi-cylindrical design.

In Fig.5 shows an implementation option, in which the channels 3 are attached to the inner surface of the outer casing and the inner surface of the inner shell and the stringers 7 extend between the bases of the channels opposite each other.

Was tested conforming to the invention design, espolla energy in violent collision with terrasim ship was so effective, the outer sheathing showed a small indentation on a large surface (this covering behaved like a membrane), and the hole was not formed.
