Description

Fire panel for vessels

The present invention relates to a fire protection panel for ships, and more particularly, to constitute a wall surface or a ceiling surface that is installed from the outside to form a closed unit compartment, and of course, the performance of the fire protection panel is excellent and its use range is expanded. The present invention relates to a fire protection panel for ships that can reduce the effort and effort required for the construction of a unit compartment, thereby enabling design work in a short time, and consequently reducing the manufacturing cost of the ship.

In general, a vessel divides the hull into a plurality of floors in a vertical direction using a plurality of decks, and divides the space sandwiched by the deck of each floor into a plurality of units in a horizontal direction by using a partition wall. It forms a closed unit compartment such as a pantry, a crew or passenger cabin, a steering room, a radio room, a loading control room, a passage room or a staircase room, a locker room or a store room, an engine room. For example, decks and bulkheads, which are unit divisions requiring Class A fire protection standards prescribed by the International Maritime Safety Treaty, are made of steel and are fixed by welding to the hull. Therefore, the deck or partition wall made of steel must remove the distortion due to the heat of welding, and it takes a long time to form the unit compartment, and there is a problem that it is difficult to design the unit compartment.

In order to solve such a problem, as disclosed in Japanese Patent Laid-Open No. H10-273093, a wall surface or a ceiling surface that forms a unit compartment in place of a steel plate partition wall is formed by imposing a fire protection panel. The technique to say is proposed. The fire protection panel used in this prior art is a structure which covered the core material, such as rock board or rock wool, with a makeup steel board, and a panel is mutually assembled by fitting the seam in the groove installed in the left and right edges. .

In the case of ships, the walls or ceilings constructed by assembling panels must meet the Class A or B standards established by the International Maritime Safety Treaty. It is necessary to improve the fire protection performance of the ceiling surface. For example, in the case of the A0 standard, it is necessary to irradiate the flame from one side of the wall surface and the ceiling surface, so that the flame does not penetrate for at least 60 minutes. As a result, in particular, the assembly parts of the panels which are likely to penetrate the flames, that is, the structures of the left and right edges of the fire protection panel become important in ships.

The flame penetrates through the assembled parts of the panel panels is a case where the deformation of each fireproof panel caused by the irradiation of the flames extends to both left and right edges, and the assembled parts of the assembled panel panels are flipped to form a gap. As a result, the left and right edges to be assembled may suppress or prevent each other's deformation, and for example, the deformation may be reduced so as not to form a gap even if the deformation is allowed. This does not necessarily mean that no deformation of the fire protection panel is allowed, but in some cases it means that the influence of the deformation does not have to reach the mutually assembled part of the panel while allowing the deformation of the fire protection panel itself.

In this regard, the fire protection panels disclosed in Japanese Patent Application Laid-open No. Hei 10-273093 are nothing more than assembling panels through a seam without directly assembling each other. Accordingly, the left and right edges to assemble do not suppress or prevent each other's deformation, and if the joints to assemble the panel mutually deform by heat, the deformation causes deformation of the left and right edges of the fire protection panel to form a gap. There is a fear that the flame penetrates from the gap.

Therefore, there is an urgent need for the development of a fire protection panel that satisfies the class A fire protection standard set by the International Maritime Safety Treaty.

The present invention has been made to solve the above problems, the fire protection panel performance, in particular, the fire protection performance of the assembly portion is excellent, as well as its use range is extended, it is possible to reduce the effort and effort required to build the unit compartment short time It is intended to provide a fire protection panel for ships that enables the design work in Korea and consequently reduces the cost of manufacturing the ship.

In order to achieve the above object, the fire protection panel for ships of the present invention sandwiches a plate-shaped insulating block molded into the panel shape by a thin steel plate and a back plate, and holds the top plate and the back plate at right and left edges. It is formed by forming the concave and convex portions of the connecting structure which is bent to form a pair, respectively, the joining width of the concave portion and the convex portion is 90% or more of the panel thickness, and the joining depth of the concave portion and the convex portion is the panel thickness. The size is 60% to 100%.

Preferably, the surface plate and the back plate is characterized in that the sheet steel of 0.4mm ~ 1.5mm ordinary steel sheet or stainless steel sheet.

Preferably, the insulating block is characterized in that the rock wool (rock wool) is formed by forming a density of 60 kg / ㎥ ~ 160 kg / ㎥.

Preferably, the insulating block is characterized in that the glass wool (glass wool) is formed by forming a density of 20kg / ㎥ ~ 300kg / ㎥.

Preferably, the insulating block is characterized by forming a ceramic wool (ceramic wool) to a density of 40kg / ㎥ ~ 300kg / ㎥.

According to the marine fire protection panel of the present invention, by assembling the mutually assembled portions of the panel with a connection structure for assembling concave and convex portions having a specific size, not only the panel unit but also the wall surface or the ceiling surface formed by assembling the fireproof panel are also known as By being able to pass Class A or B standards set by the Safety Treaty, the scope of use of fire protection panels in ships is expanded, reducing the effort and effort required to construct unit compartments, and enabling design work in a short time. This results in an effect of reducing the manufacturing cost of the vessel.

Hereinafter, with reference to the accompanying drawings will be described in more detail the fire protection panel for ships of the present invention.

Edges of unit compartments constructed using A partial perspective view showing a minute.

As shown in Fig. 1, the fire protection panel 1 of the present embodiment is formed by bending a conventional steel sheet having a plate thickness of 0.6 mm to be symmetrically shaped as opposed to the front and rear direction (direction connecting the upper left and the right in Fig. 1). The surface plate 11 and the back plate 12 hold | maintain the heat insulation block 13 shape | molded by the outer surface part of the panel at the density of 120 kg / m <3>. In the fire protection panel 1 of this embodiment, the panel thickness Hp is 50 mm. Although the heat insulation block 13 is exposed in the up-down direction, this fire prevention panel 1 is an assembly part of fire protection panel 1 mutually at both edges of the left-right direction, and the recessed part 14 and the convex part ( 15) are formed respectively. As will be described later, the unit compartment can be made by assembling a plurality of fire protection panels 1 of the present embodiment with respect to the bottom surface 4 made of, for example, a steel sheet to form the wall surface 2 and the ceiling surface 3. (See FIGS. 8-10)

The fire protection panel (1) of the present invention is characterized in that the assembly of the fire protection panel (1) mutually has a specific connection structure in order to satisfy the class A fire protection standards and B fire protection standards prescribed by the International Maritime Safety Treaty. Have As shown in Figs. 2 and 3, the fire protection panel 1 according to the present embodiment has a coupling width H1 and H2 of the concave portion 14 and the convex portion 15 in the connecting structure. It is about 93% in size, and the depths of engagement D1 and D2 of the concave portion 14 and the convex portion 15 are the same size as the coupling widths H1 and H2, that is, about the panel thickness Hp. It is 93% size, and comprises the square recessed part 14 and the convex part 15 in planar view.

As shown in FIG. 2, the concave portion 14 includes a surface plate such that the protrusion amount of the flange 1411 surrounds each of the flanges 1411 of the reinforcement 141 having a c-shaped cross section having about 93% of the panel thickness. (11) and back plate 12 are respectively folded to form a recessed outer joining surface 143 which protrudes in parallel to face in the front and back direction, and the heat insulating block which the surface plate 11 and the back plate 12 sandwich. The end face 131 of 13 is in contact with the outer surface 1412 of the reinforcing material 141. Accordingly, the depth of engagement D1 of the recess 14 is approximately the amount of protrusion of the flange 1411 of the reinforcing member 141, which is about 93% of the panel thickness. In addition, when the plate thickness of the steel plate constituting the reinforcing material 141 is 0.6 mm, the thickness of each of the recess outer engagement surfaces 143 is the plate thickness of the surface plate 11 and the back plate 12 (0.6 mm). The plate thickness (0.6 mm) of the reinforcing material 141 is added to each other, that is, 1.8 mm to 2 times (1.2 mm) of, and the strength or rigidity required to clamp the convex portion 15 to be joined can be secured. have. Then, the joining width H1 of the recess 14, which is obtained by subtracting the thickness of each recess outer joining surface 143 from the panel thickness Hp, is about 93% (= (50 mm −) of the panel thickness Hp. 1.8mmX2) / 50X100%).

As shown in FIG. 3, the convex part 15 has the inside of the convex part which formed the step | step 151 of the sum total of each plate thickness and the said thickness of the said reinforcing material 141 on the surface plate 11 and the back plate 12 as shown in FIG. The coupling surface 152 is formed in the range of about 93% of the panel thickness from the end surface 131 of the heat insulation block 13 which the surface plate 11 and the back plate 12 hold | maintain. The convex portion engaging surface 152 constitutes the convex portion connecting surface 153 folded in a predetermined width from the end edge, and the convex portion connecting surface 153 does not protrude from the end face 131 of the insulating block 13. Is being pressed. As a result, the depth of engagement D2 of the convex portion 15 becomes about 93% of the panel thickness, similar to the range in which the convex portion inner engaging surface 152 is formed. In addition, when the plate thickness of the reinforcing material 141 is set to 0.6 mm as described above, the step 151 of each convex portion engaging surface 152 with respect to the surface plate 11 or the back plate 12 is a surface plate. The thickness of the reinforcing material 141 combined with the plate thickness (0.6 mm) of the thickness (0.6 mm) of the 11 or the back plate 12 is 1.8 mm. Then, the joining width (H2) of the convex portion (15) remaining after subtracting the step (151) of each convex portion engaging surface 152 with respect to the surface plate 11 or the back plate 12 from the panel thickness (Hp). Silver becomes about 93% (= (50mm-1.8mmX2) / 50X100%) of the panel thickness Hp.

As described above, the concave portion 14 and the convex portion 15, which are actual structures in the fire protection panel 1 of the present invention, have the coupling widths H1 and H2 and the coupling depths D1 and D2 with respect to the panel thickness Hp. Because of the high ratio, the firmly assembled parts of the fire protection panels 1 are realized. In addition, in particular, since the ratio of the coupling depths D1 and D2 to the panel thickness Hp is high, it is possible to suppress or prevent deformation of the convex outer surface continuous to the surface plate 11 or the back plate 12, for example Even when the surface plate 11 or the back plate 12 is deformed by heat, even when the outer surface of the convex portion is deformed, the coupling relationship of the connection structure is not broken, so that the assembled parts of the fire panel 1 are mutually assembled. No gaps are formed in the consequently the penetration of heat can be prevented.

Here, the shape of the outer surface of the convex portion is proportional to the amount of heat applied to the surface plate 11 or the back plate 12 and inversely proportional to the thermal conductivity of the insulating block 13. That is, when the thermal conductivity of the insulating block 13 is low, for example, the heat applied to the surface plate 11 is difficult to be transmitted to the back plate 12 and accumulates in the surface plate 11 to greatly deform the outer surface of the convex portion. When the thermal conductivity of the insulating block 13 is high, the heat applied to the surface plate 11 is also transmitted to the back plate 12 so that the convex continuous to the surface plate 11 can be emitted from the back plate 12. The deformation of the negative outer surface can be suppressed. As a result, the protection panel 1 of the present embodiment forms the concave portion 14 and the convex portion 15 of the connection structure as described above, and at the same time sets the thermal conductivity of the thermal insulation block 13 to be relatively high. The density of the rock wool which comprises the block 13 is 120 kg / m <3>. The density of the rock wool formed in this way is the size of the fire protection panel 1, the coupling depths D1 and D2 of the concave portion 14 and the convex portion 15, which are the connecting structures, and the coupling widths H1 and H2 or the surface plate ( 11) and the thickness of the back plate 12, it is desirable to determine appropriately in accordance with the Class A fire protection standards and Class B fire protection standards prescribed by the International Maritime Safety Treaty.

The connection structure in the fire protection panel 1 of this invention can also be comprised as follows. As shown in FIG. 4, the recess 14 protrudes the surface plate 11 and the back plate 12 as it is to form an opposing recess outer joining surface 143, and the surface plate 11 and the back plate. The end face 131 of the insulating block 13 sandwiched by (12) can be formed in a recessed position by only about 93% of the panel thickness from the end edge of the recess outer engaging surface 143. The depth of engagement D3 of the recess 14 is set to about 93% of the panel depth as described above, but the width of engagement H3 is about 98% of the panel thickness Hp (= (50 mm-0.6 mmX2). / 50x100%). Accordingly, the pair of convex portions 15 have convex inner engagement surfaces 152 in which the step 151 corresponding to the thickness of each plate is formed on the surface plate 11 and the back plate 12 as shown in FIG. 5. Is formed in the range of about 93% of the panel thickness from the end surface 131 of the heat insulation block 13 which the surface plate 11 and the back plate 12 hold | maintain, and the joining width H4 and the joining depth D4 are carried out. Is matched to the coupling width H3 and the coupling depth D3.

In addition, as shown in FIG. 6, the recessed part 14 folds the surface plate 11 and the backplate 12, respectively, and overlaps two sheets, and forms the recessed outer coupling surface 143, and the surface plate 11 And the end face 131 of the insulating block 13 sandwiched by the back plate 12 are formed at a position of about 93% of the panel thickness from the end edge of the concave outer engaging surface 143. can do. Here, in the recess 14 of this other embodiment, the recessed connection surface 144 is formed using the folded surface plate 11 and the back plate 12 to push the end face 131 of the insulating block 13. Doing. The depth of engagement D5 of the recess 14 is about 93% of the panel depth as described above, but the width of engagement H5 is about 95% of the panel thickness Hp (= (50mm-0.6mmX2X2) / 50X100%). As a result, the pair of convex portions 15 are formed on the front plate 11 and the back plate 12 as shown in FIG. 7. 152 is formed in the range of about 93% of the panel thickness from the end surface 131 of the heat insulation block 13 which the surface plate 11 and the back plate 12 hold | maintain, and the joining width H6 and the joining depth ( D6) is matched with the coupling width H5 and the coupling depth D5.

Next, the unit compartment comprised using the fire prevention panel 1 of this embodiment (FIGS. 1-3) is demonstrated. The fire protection panel 1 of this invention can be used for both the direct unit compartment comprised on the deck of a ship, or the modular unit compartment comprised as the partition module constructed outside a ship. The direct unit section has a deck made of a steel sheet as the bottom surface 4, and the modular unit section has only a steel sheet or a steel sheet provided with a reinforcing floor frame. In the latter modular unit section, when only the steel sheet is the bottom surface 4, the steel sheet serving as the bottom surface 4 is grounded on the deck of the ship, and the steel sheet is welded and fixed to the deck. In addition, when the steel plate provided with the bottom frame is made into the bottom surface 4, the deck of the ship is opened by the said bottom surface 4, the bottom surface 4 is put into the opening, and the bottom surface 4 is made into the deck. It is also possible to combine.

As shown in FIG. 8, the wall surface 2 of the unit compartment constitutes a base frame 41 fixed on the bottom surface 4 along the horizontal cross section of the unit compartment by welding the C-type steel plate downward. The panel receiving port 42 made of a channel member opened upward on the base frame 41 is fixed by welding, and a plurality of fire protection panels 1 are fitted along the panel receiving port 42. . Since the panel receiving port 42 also serves as a guide member for aligning the row direction of the fire protection panel 1 constituting the wall surface 2, the channel is long along the continuous wall surface 2 as in the present embodiment. It is preferable to use ash. Further, the reason for fixing the panel receiving port 42 to the base frame 41 composed of the C-shaped steel plate fixed to the bottom surface 4 is to improve the rigidity of the steel plate constituting the bottom surface 4 and at the same time. This is to improve the rigidity of the channel material made of a thin steel plate to maintain a stable established state of the wall surface (2).

The ceiling surface 3 of the unit compartment faces the panel support 21 made of a channel member provided with the same inner flange as the panel receiving port 42 with respect to the fire protection panel 1 constituting the wall surface 2. A plurality of fire protection panels 1 are horizontally coupled to the inner flange of the panel support 21. The panel supporter 21 serves as a guide member for aligning the row direction of the fire protection panel 1 constituting the wall surface 2, and as a horizontal plane of the fire protection panel 1 constituting the ceiling surface 3. Since it also has a role as a guide member to match the castle, it is preferable to use a long channel material along the continuous ceiling surface 3 as in this embodiment. However, if it operates as the same guide member, for example, as shown in Fig. 9, the panel support 22 made of an angle member constituting the inner flange is screwed into the inside of the fire protection panel 1 of the wall surface 2; The ceiling surface 3 may be formed on the inner flange of the panel support 22 so as to horizontally cover the plurality of fire protection panels 1.

The fire protection panel 1 constituting the wall surface 2 and the ceiling surface 3 is continuous without a mutual gap by a real system structure, and is screwed to the panel receiving port 42 or the panel support 21, respectively. Constrained and fixed in position. Here, the ceiling surface 3 with respect to the wall surface 2 on all sides is because the panel support 21 is coupled (see FIG. 8) or screwed (see FIG. 9) to the upper edge of each of the wall surfaces 2. There is no gap in the wall surface 2 and the ceiling surface 3. On the other hand, for example, as shown in FIG. 10, the corner part (edge part) of the wall surface 2 of the front side, and the side wall surface 2 is screwed inward by screwing the panel joint member 23 which consists of angle materials toward the inside. The gap between the fire protection panels 1 constituting the corners can be completely prevented. If the wall surface (2) and the ceiling surface (3) connected without gaps satisfy the Class A fire protection standard or the Class B fire protection standard prescribed by the International Maritime Safety Treaty, the bottom surface 4 is composed of steel plate. The unit compartment of this embodiment satisfies the Class A fire protection standard or the Class B fire protection standard prescribed by the International Maritime Safety Treaty.

The actual unit compartment covers a decorative sheet over a plurality of fire protection panels 1 constituting a floor covering such as a cremating tile on a steel plate constituting the bottom surface 4 or a wall surface 2 or a ceiling surface 3. Stick to improve the appearance and improve the texture of each. For example, when the unit standard is a cusine, the bottom surface 4 preferably has a water repellent makeup tile because it is preferable to have excellent drainage. In addition, by attaching a stainless film over the plurality of fire protection panels 1, the wall surface 2 can improve the apparent integrity as the wall surface 2, improve the texture of the whole wall surface 2, and can also improve fire resistance. As a result, the modular unit compartment can be constructed outside the ship, and thus the design work attaching the makeup tile or the makeup sheet is also free, and as a result, it is possible to provide a cooking chamber of higher quality than the conventional one.

EXAMPLE

Not only the fire protection panel of the present invention but also all the fire protection panels satisfy the Class A fire protection or Class B fire protection standards prescribed by the International Maritime Safety Treaty, but are not determined by structural specifications, but are determined by the International Maritime Organization (IMO). Pass the fire test (see Resolution A. 754 (18)) in accordance with the Uniform Code of Fire Tests (FTP Code Parts 1 and 3). Therefore, the fire protection panel of this invention was tested and the fire test was carried out for the A0 standard (when irradiating the flame for 60 minutes, there is no penetration of the flame and the maximum heat radiation amount (Ew) is less than 56.5 kW / m 2).

The test body is composed of four fire protection panels of the above example (see Fig. 1) in a substantially square test frame to form a wall surface, and irradiated with a gas burner on the front (surface plate) side of the wall surface to back the back surface (back plate). The amount of heat radiation from the side was measured until 60 minutes after the irradiation was started (0 minutes). Four fire prevention panels were used, and the wall surface of 2500 mm in height and 2440 mm in width was comprised. Each fireproof panel had a panel thickness of 50 mm, the surface plate and the back plate consisted of a cold rolled steel plate having a plate thickness of 0.6 mm, and the insulating block consisted of glass wool having a density of 120 kg / m 3. The joining width of the concave and convex portions constituting the connecting structure was about 46 mm, and the joining depth was 46 mm in the same manner. As a result of the test, it was confirmed that the maximum amount of heat radiation was less than the predetermined value even after 60 minutes of irradiation of the flame, and the penetration of the flame from the assembled parts of the panels was not seen and the A0 standard was satisfied.
