Description

Blast Wall {BLAST WALL}

The present invention relates to blast walls.

Generally, a ship or a marine structure is divided into a plurality of layers in a vertical direction using a deck (deck), and a space sandwiched between decks of each layer is divided in a horizontal direction using a partition wall, A housing area is formed such as a wheelhouse, an engine room, a passage or a stairway. These residential areas are crowded with passengers, which can cause large-scale casualties in the event of a fire accident. In addition, various facilities necessary for living are disposed in a residential area, so that fire is liable to be transferred, which may lead to an explosion.

Therefore, the bulkheads that compartmentalize the residential area are required to have Class B fire rating. These compartments should be completely blocked from the deck to the upper deck. On the other hand, there is a gap between the cabin and the upper part of the deck, and a class B fire rating is required for the gap. Accordingly, the wall or ceiling (partition wall) forming the closed unit compartment constituting the residence area above the deck is generally made of a steel plate made of a steel material so as to withstand the explosion load and to prevent the fire from being easily transferred. A partition made of a steel material performing such a function is called a blast wall or an explosion-proof wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an embodiment of a blast wall according to the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, Is omitted.

FIG. 1 is a view showing an offshore structure having a blast wall, and FIG. 2 is a view showing a blast wall according to an embodiment of the present invention.

Referring to FIGS. 1 and 2, a blast wall 10 according to an embodiment of the present invention may include a plate member 100 and an arcing member 200.

The plate member 100 may extend upwardly from the deck 11. The deck 11 may provide a cargo loading space or a residential area 13 of a person with an offshore structure 1 or a member mounted on the ship. 1, an example of an offshore structure 1 to which a blast wall is applied is shown as an example, but the present invention is not limited thereto.

Herein, the offshore structure 1 is a floating offshore structure, for example, a floating production storage and offloading (FPSO), a floating production unit (FPU) Including LNG-FPSO (Liquefied Natural Gas), Floating Production Storage and Offloading (LNG-FPU), Liquefied Natural Gas - Floating Production Unit (LNG-FPU) .

The plate member 100 may be a bulkhead separating the cargo loading space or the occupation 13 of the person. The plate member 100 may be plate-shaped. A plurality of plate members 100 may be combined to form one partition.

The plate member 100 may be formed of a material including steel, thereby preventing the flame from propagating outside the plate member 100, and may withstand an explosion load in the event of an explosion, but may be damaged in a high temperature environment .

The fire-fighting member 200 may cover one side of the plate member 100. Here, 'cover' means that the fireproof member 200 covers the plate member 100, and the fireproof member 200 may be in contact with the plate member 100 or may be spaced apart. The fire shield 200 may cover both sides of the plate member 100.

The fireproof member 200 may perform an insulation function to prevent the plate member 100 from being damaged by heat.

The fire-fighting member 200 may be composed of airgel.

In general, aerogels have a low thermal conductivity, excellent insulation performance, and are structurally robust enough to withstand explosive loads. In addition, since the density is low and the weight is light, the weight of the entire marine structure 1 is remarkably reduced by using the fire-fighting member 200 as a heat insulating material, so that the operating efficiency of the marine structure 1 can be increased.

The fire-fighting member 200 may be made of a material including cryogel Z or pyrogel XT. Cryzel and pyrogel are a type of airgel, and Cryuzel is a low temperature aerogels used in cryogenic and lower temperature regions in LNG, gas processing and petrochemical markets. Pyrogel is used in smelting, It is a high temperature airgel used in high temperature fields such as solar market. Since the importance of adiabatic heat is different depending on the installation position of the blast wall in the fire-fighting member 200, a cryogen or pyrogel can be selectively used as needed, and a cryogen and a pyrogel can be mixed in an appropriate ratio.

The fire-fighting member 200 may have a plate shape. When the fire-fighting member 200 is in the form of a plate, the thickness of each fire-fighting member 200 may be different depending on necessity. The arcing member 200 may be formed in the same area as the plate member 100.

FIG. 3 is a view illustrating a state in which a blast wall is disassembled according to an embodiment of the present invention, and FIG. 4 is a view showing a coupling member 300.

Referring to FIGS. 3 and 4, the blast wall 10 according to an embodiment of the present invention may further include a coupling member 300 and a buffer member 400.

The engaging member 300 can engage the fire-fighting member 200 with the plate member 100. The coupling member 300 may include a coupling pin 310, a plurality of projections 311, and a coupling cap 330.

The coupling pin 310 may be coupled to one surface of the plate member 100. A plurality of the coupling pins 310 may protrude from the surfaces adjacent to the respective corners of the plate member 100 so that the flap members 200 are not separated from the plate member 100. The end of the coupling pin 310 may be tapered so as to easily penetrate the fire-fighting member 200 and the buffer member 400.

The plurality of protrusions 311 may protrude from the outer circumferential surface of the coupling pin 310. The plurality of protrusions 311 may protrude obliquely from the coupling pin 310 toward the plate member 100. [ The plurality of protrusions 311 may be spaced apart from each other along the longitudinal direction of the coupling pin 310. Due to the shape of the protrusion 311, the coupling pin 310 is easy to be coupled with the coupling cap 330, but may be difficult to disassemble. The protrusion 311 may be formed of a flexible material, for example, a material including silicon.

The coupling cap 330 may be coupled to an end of the coupling pin 310 protruding through the fireproof member 200. The coupling cap 330 may have a plurality of detent grooves formed on the inner circumferential surface thereof so as to receive a plurality of protrusions 311 therein. The plurality of escape prevention grooves can be engaged with the plurality of projections 311.

The coupling can be made by inserting the end of the coupling pin 310 into the coupling cap 330. When the thickness of the fireproof member 200 is different or the plurality of fireproof members 200 are used in a stacked manner, the fireproof member 200 may be coupled to the plate member 100. [

A heat insulating coating layer 331 may be formed on the outer surface of the coupling cap 330.

The heat insulating coating layer 331 is coated on the outer peripheral surface of the coupling cap 330 to prevent heat from being transmitted to the plate member 100 through the coupling cap 330 and the coupling pin 310 when the flame is generated.

The heat insulating coating layer 331 may be formed by applying a heat insulating material to the outer circumferential surface of the coupling cap 330. The insulation may be liquid type PFP (passive fire protection) of epoxy type or liquid aerogels.

When the heat insulating coating layer 331 is disposed on the outer circumferential surface of the coupling cap 330, the heat insulating coating layer 331 may be formed thicker to improve the heat insulating performance.

The buffer member 400 may be interposed between the plate member 100 and the fireproof member 200.

The buffer member 400 can buffer the lifting between the face of the plate member 100 and the face of the fire-fighting member 200.

The buffer member 400 may be attached to the surfaces of the plate member 100 and the fireproof member 200 with adhesives formed on both sides thereof. The detachment of the fireproof member 200 from the plate member 100 can be prevented even if the coupling cap 330 is disassembled from the coupling pin 310 due to the buffer member 400. [

The buffer member 400 may be formed of a material such as rubber, silicone, or sponge, and may perform an additional thermal insulation function in this case.

5 is a view showing a blast wall 10 according to another embodiment of the present invention.

Referring to FIG. 5, the fire-fighting member 200 may be formed of an airgel coating layer.

The airgel coating layer may be formed by spraying liquid aerogels onto one surface of the plate member 100. The liquid aerogels may be injected from the nozzles and may be formed directly by a tool such as a brush. Accordingly, the process can be simplified and the process time can be shortened, so that the production efficiency can be increased.
