Description

Fire protection panel and fire protection device using the fire protection panel

The present invention relates to a fire protection panel that blocks the propagation of a flame when a fire occurs, and more particularly, there is no thermal deformation by the flame by absorbing water supplied from the outside and holding it for a long time, and it does not burn and does not burn toxic gas It relates to a fire protection panel and a fire protection device using the fire panel, which does not emit.

A sandwich panel widely used as a building panel has a basic structure of a plate-shaped insulating material and two outer plates covering the front and rear surfaces of the insulating material. The insulating material embedded between the outer plates includes, for example, styrofoam, urethane foam, glass wool, mineral wool, and the like. These sandwich panels are pre-fabricated in a factory according to the intended use, and then cut and assembled to an appropriate size at the job site.

Although the sandwich panel has the characteristics that mass production is possible, assembly and installation is relatively simple, and the unit price is low, it has a disadvantage in that it is vulnerable to fire. In other words, the low flash point of the insulating material ignites easily and generates a large amount of toxic gas during combustion.

In order to solve this problem, a gypsum board panel (Steel Gypsum board Panel) in the form of attaching a gypsum board to an iron plate is sometimes used. However, in case of a fire, the adhesive for fixing the iron plate and the gypsum board is melted, and the iron plate and the gypsum board are decomposed, thereby losing their function.

As a background technology related to a sandwich panel, there is a sandwich panel disclosed in Korean Patent Publication No. 10-1048860 and a method for manufacturing the same. The disclosed sandwich panel comprises: a pair of surface plates; a panel frame formed so that the inside becomes a receiving part by a side member sealing the four sides between the surface boards; And it is filled in the receiving part, and is excellent in heat insulation, heat insulation and flame retardancy, and is composed of a filler formed by mixing a non-toxic and heat-resistant inorganic binder with rice husk as the main material, which is an eco-friendly material. However, the conventional sandwich panel described above has disadvantages in that the panel frame is assembled from a surface plate, a side member, and a diaphragm, so that the structure is complicated and its own weight is heavy.

As a panel that can be used for construction or other industrial purposes, there is a need for a fire protection panel that is light and does not burden construction, does not burn, and does not generate soot or toxic gas.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is an exploded perspective view of a fire protection panel 10 according to an embodiment of the present invention.

As shown, the fire protection panel 10 according to the present embodiment includes a panel body 12 and a receiving case 18 . The panel body 12 takes the shape of a substantially rectangular plate, and depending on use, as shown in Figs. ) can be configured.

The panel body 12 includes a retention form plate 14 and a cover part.

The retention foam plate 14 is a square plate made of melamine foam or phenol foam having an open cell structure. An open cell is a micropore of an open structure, and is a space for accommodating fire-fighting water supplied from the outside in the event of a fire.

The retention form plate 14, in a state of absorbing fire-fighting water, retains fire-fighting water through the action of the surface tension of the water itself and the adsorption force with the fire-fighting water. In other words, water molecules of fire water accommodated in each cell have a property of being adsorbed to the inner wall surface of the cell and have their own surface tension, so they do not escape from the cell and remain inside the cell. . This is the same principle as the well-known capillary phenomenon. The fire-fighting water retention force of the retention form plate 14 corresponds to the sum of the above-described adsorption force and surface tension.

For reference, if water is continuously poured in the state where 100% of water is absorbed in the retention form plate 14, some of the water is not absorbed and flows along the outer surface of the retention form plate 14, and the rest of the cells pass and descend At this time, some of the water that had previously entered the cell drains from the cell to the bottom, and the newly poured water takes its place.

In particular, melamine foam and phenol foam are non-flammable materials. Since the non-combustible material holds water inside, when a fire occurs, the retention form plate 14 itself forms a water wall made of water.

The cover part is a cover plate 16 that covers the front and back surfaces of the retention form plate 14 to block direct contact between the retention form plate and the flame and suppress the evaporation of water for firefighting. The cover plate 16 is a metal plate having a certain thickness.

The cover plate 16 is not thermally deformed even in contact with a flame. The reason is that the relatively cold retention form plate 14 is being interviewed. In the event of a fire, cold fire water is continuously supplied through the water supply pipe (57 in FIG. 7), and the supplied fire water is filled in the retention foam plate 14, so the fire water maintained inside the retention foam plate 14 is Even when boiling, the cover plate 16 is maintained at a temperature of 100 DEG C or lower. For a metal plate, a temperature of 100° C. is not high enough to deform.

As a result, even if the panel body 12 in this embodiment is in a flame during a fire, as long as fire water is continuously supplied, it is not deformed and maintains the first construction state as it is. In addition, even if the water for firefighting is cut off, the retention form plate 14 does not burn, so at least no toxic gas is generated.

The receiving case 18 is included in the fire protection panel 10 of this embodiment as a container for providing the receiving space 18a opened upward. The receiving case 18 accommodates the lower end of the panel body 12 and temporarily accommodates the fire-fighting water flowing downward when the fire-fighting water is excessively supplied.

The receiving case 18, in particular, also serves to slow down the descending speed of water (which passes downwardly through the inside of the retention form plate 14). As mentioned above, when fire-fighting water is continuously supplied from the outside, some of the fire-fighting water descends through the cells inside the retention form plate 14. It falls out immediately, but if the receiving case 18 is installed, fire water is once clogged in the receiving case, and the descending speed is slowed to some extent. When the descending speed is slow, the flow rate per unit time of the fire-fighting water passing through the retention form plate 14 is reduced. This means that the supply flow rate of firefighting water supplied through the water supply pipe can be reduced. In other words, with a relatively smaller amount of fire water (compared to when the receiving case 18 is not present), the ability of the fire protection panel 10 can be maintained to the maximum.

2A and 2B are views for explaining a modified example of the fire protection panel 10 shown in FIG. 1 . 2b is a side cross-sectional view of FIG. 2a.

As shown, the retention form plate 14 interposed between the both side cover plates 16 is composed of two unit retention forms 14a and 14e in combination. The lower unit retention form 14a provides a triangular groove 14b open upward, and the upper unit retention form 14e is fitted into the triangular groove 14b. In particular, the upper unit retention form 14e has a lower relative density than the lower unit retention form 14a. That is, the holding power of water is smaller than that of the lower unit retention form 14a. Less water retention means that water gets through less difficult when the firefighting water is constantly pouring down.

In this way, by forming a triangular groove 14b in the lower unit retention form 14a, and inserting a relatively low-density upper unit retention form 14e into the triangular groove 14b, initial firefighting water is added to the retention form plate. It can lead to the lower end of (14) more quickly.

FIG. 3 is a cutaway perspective view showing another modified example of the fire protection panel 10 shown in FIG. 1 .

Referring to FIG. 3 , it can be seen that the retention form plate 14 is laminated with four unit retention forms 14f, 14g, 14h, and 14k. Each of the unit retention forms 14f, 14g, 14h, and 14k takes the form of a block in the form of a hexahedron and is vertically stacked. In addition, the density of the four unit retention foams decreases from bottom to top. That is, the density of the lowermost unit retention form 14f is the largest, and the density of the unit retention form 14k positioned at the uppermost layer is the lowest. This arrangement is taken into consideration so that the continuously supplied fire-fighting water quickly moves toward the lower end of the retention form plate 14 and fills each unit retention form with an appropriate amount of fire-fighting water.

4 is a cutaway perspective view showing another modified example of the fire protection panel 10 of FIG. 1 .

Referring to the drawings, it can be seen that a vertical guide passage 14m is formed in the center of the retention form plate 14 . The guide passage (14m) is a passage having a certain inner diameter, and accommodates the extended water supply pipe (59) as shown in FIG. The extended water supply pipe 59 is a branch pipe of the water supply pipe 57, and serves to guide the fire water passing through the water supply pipe to the vertical lower part. By forming the guide passage (14m) and embedding the extended water supply pipe (59) in the guide passage (14m), it is possible to quickly reach the fire water to the lower end of the retention form plate (14).

5A and 5B are cutaway perspective views illustrating another modified example of the fire protection panel 10 shown in FIG. 1 . Figure 5b is a side cross-sectional view of Figure 5a.

As shown, the retention form plate 14 is accommodated in the cover case 21 . The cover case 21 provides an accommodating space 21a for accommodating the retention form plate 14 and is opened upward. The cover case 21 plays the same role as the cover plate 16 described above. In addition, since the lower portion of the cover case 21 is blocked, the receiving case 18 does not need to be used. In addition, since both sides of the cover case 21 are blocked, when configuring the firewall body 51, butt welding with the side surface of the neighboring cover case 21 is also possible.

6 is a cutaway perspective view showing a modified example of the fire protection panel 10 shown in FIG. 5A.

Referring to the drawings, it can be seen that the reinforcing rib 21b is further formed inside the cover case 21 . The reinforcing ribs 21b are for improving the strength of the cover case 21 . Of course, the receiving space 21a is partitioned by the reinforcing ribs 21b.

7 is a view for explaining the configuration of a fire protection device 50 according to an embodiment of the present invention. 8 is a cross-sectional view taken along line D-D of FIG. 7 .

Hereinafter, the same reference numerals as the above reference numerals indicate the same members having the same functions.

As shown, the fire protection device 50 according to the present embodiment includes a firewall body 51 constructed of a plurality of fire protection panels 10 , and a fire-fighting water supply for supplying fire-fighting water to the upper end of the firewall body 51 . includes wealth. The receiving case 18 was omitted from the fire protection panel 10 . This is because the lower receiving beam 53 to be described later serves as the receiving case 18 .

A plurality of fire panels 10 are fixed to each other through separate fixing parts (not shown) in a state in which they are in close contact with each other in the lateral direction, and have an upper receiving beam 55 at the upper end and a lower receiving beam 53 at the lower end. .

The lower receiving beam 53 is a straight member obtained by bending a metal plate having a certain width upward in the width direction, and receives and fixes the lower end of the firewall body 51 . The lower receiving beam 53 and the cover plate 16 are fixed with rivets or screws. The lower receiving beam 53 serves as both the role of the above-described receiving case 13 and the role of fixing the firewall body 51 to the indoor floor surface (A).

The upper receiving beam 55 is also a straight member obtained by bending a metal plate having a certain width, and receives and fixes the upper end of the firewall body 51 . The upper receiving beam 55 serves to fix the upper end of the firewall body 51 to the indoor ceiling (B). In particular, a piping space (55a) is provided between the upper receiving beam (55) and the fire protection panel (10). The piping space 55a is a passage through which the water supply pipe 57 passes.

The water supply pipe 57 is a pipe for guiding fire-fighting water supplied from the outside, and is disposed parallel to the upper end of the firewall body 51 . It is to be located in the vertical direction of the upper portion of the retention form plate (14). The water supply pipe 57 is horizontally supported by the fixing bracket 55b inside the upper receiving beam 55 . The water supply pipe 57 is piped on the upper part of the firewall body 51 , and the water supply pipe 57 is not seen by being covered by the upper receiving beam 55 .

In addition, a plurality of water supply nozzles (57a) are installed in the lower portion of the water supply pipe (57). The water supply nozzle 57a ejects firefighting water supplied through the water supply pipe 57 toward the firewall. That is, by ejecting the fire-fighting water downward toward the retention foam plate 14, the retention foam plate retains the fire-fighting water.

Reference numeral 58 denotes a connecting pipe. The connecting pipe 58 is branched from the water supply pipe 57 and horizontally extended, and has a sprinkler 58a at the extended end. When fire-fighting water is ejected through the water supply nozzle 57a, the sprinkler 58a also operates at the same time to spray fire-fighting water.

9 is a view for explaining a modified example of the fire prevention device 50 according to an embodiment of the present invention.

Referring to the drawings, it can be seen that a guide passage 14m is formed in each fire panel 10 constituting the firewall body 51 , and an extended water supply pipe 59 is inserted into the guide passage 14m. The extended water supply pipe 59 is a pipe branched downward from the water supply pipe 57 and has a plurality of water supply nozzles 59a. The water supply nozzle (59a) ejects fire-fighting water coming down through the extended water supply pipe (59) so that the retention form plate 14 holds fire-fighting water.

10 is a side view showing a state in which the fire protection device 50 according to an embodiment of the present invention is applied to the storage tank 61, and FIG. 11 is a cutaway perspective view showing a part of the fire protection device shown in FIG.

The storage tank 61 is a cylindrical tank containing a combustible material, for example, oil, gas, or volatile chemical. The fire protection device 50 according to this embodiment surrounds the storage tank 61 , and builds a wall of water around the storage tank to cool the storage tank 61 . In summer, the storage tank 61 itself is heated by the hot solar heat, thereby increasing the risk of explosion or fire. At this time, the storage tank 61 is cooled through the fire protection device 50 .

The fire protection device 50 shown in FIG. 10 protects the storage tank 61 and cools the storage tank when the temperature of the storage tank rises to prevent fire. includes wealth. The firewall body 51 takes a curved shape so as to be in close contact with the outer surface of the storage tank 61 .

The fire-fighting water supply unit supplies fire-fighting water to the inside of the retention form plate when the temperature of the storage tank rises so that the retention form plate holds fire-fighting water, and a plurality of horizontally extending inside the firewall body 51 . It includes a water supply pipe 65 , a pump 67 for supplying water to the water supply pipe 65 , and a water supply pipe 68 .

The water supply pipe 65 is a pipe having a plurality of discharge holes 65a, and is inserted into the pipe mounting passage 14p formed in the retention form plate 14 for fire fighting in the retention form plate 14. spit out the number

Reference numeral 63 denotes an intermediate beam for fixing the adjacent fire panel 10 up and down. In addition, the upper receiving beam 55 located at the upper end of the firewall body 51 supports the upper end of the uppermost fire protection panel 10 so as not to be displaced in the circumferential direction.

When the fire-fighting water supply unit having the above configuration is operated, the retention form plate 14 inside the firewall body 51 is wetted with fire-fighting water and holds fire-fighting water. In addition, if the firefighting water is continuously supplied, the surplus firefighting water flows out of the firewall body 51 and flows down to the ground. The firewall body 51 is wetted with fire-fighting water to cool the storage tank 61 .

The body 74 is composed of a combination of a plurality of plate-shaped hollow plates 74a having an inner space 74c and is opened forward. Each hollow plate 74a is a hollow plate manufactured by bending and welding an iron plate, and forms the left and right side walls, the rear wall, the ceiling plate, and the bottom plate of the main body 74 . In particular, the inner space 74c of the hollow plate 74a constituting the left and right side walls, the rear wall and the ceiling plate are all connected. In other words, the fire-fighting water flowing into the ceiling plate flows down the left and right walls and the rear wall. The hollow plate 74a serves as the fire protection panel 10 .

Industrial equipment 72 is built in the storage space 71a of the main body 74 . The industrial equipment 72 is sealed in the main body 74 when the door 77 is closed.

Reference numeral 74k denotes a bottom through hole. The lower through-hole (74k) is a hole through which the fire-fighting water supplied through the fire-fighting water supply unit can be drained. When firefighting water is continuously supplied, the surplus firefighting water is drained to the outside of the firefighting cabinet 71 through the lower through-hole 74k.

The fire fighting water supply unit includes a water supply pipe 76 , a water tank 75 , and a connection tube 76a. The water tank 75 receives and temporarily stores fire-fighting water supplied from the outside through the water supply pipe 76 . Water in the water tank 75 is supplied to the inner space 74c of the body 74 through the connection tube 76a. The firefighting water introduced into the inner space 74c spreads horizontally and flows down to both side walls and the rear wall of the main body 74 by the action of gravity, and a portion is supplied to the door 77 .

The retention form plate 14 is built into the inner space of the main body 74, is wetted with fire water supplied from the fire water supply unit, and holds fire water. The fire protection cabinet 71 maintains a cooled state by the fire water.

On the other hand, the door 77 is a hinged door connected to the front of the main body 74 by a hinge 77r, and a hollow plate 77a manufactured by pressing and welding a metal plate, and the interior of the hollow plate 77a. Consists of a retention form plate 14 installed in the space (77b). The door 77 constitutes one fire protection panel 10, and seals the storage space 71a in a closed state.

The inner space 77b of the hollow plate 77a communicates with the inner space 74c of the main body 74 in the closed state of the door 77, and is blocked in the open state. That is, in a state in which the door 77 is closed, water for firefighting can be received.

To this end, a slit-type upper hole 77c and a shutter 77e are provided at the upper end of the hollow plate 77a, and a drain hole (74f in FIG. 14) is formed on the bottom surface of the ceiling part of the hollow plate 74a of the body 74, have.
