The present invention relates to a fireproof panel and a method of manufacturing the same, in particular, excellent in fire resistance and durability, and the core material is not exposed to the outside to improve the safety, the fireproof panel and its manufacturing method can be improved workability during manufacture and construction It is about.

In general, in the building, various functional panels are used as interior materials and exterior materials to ensure insulation, sound absorption, fire resistance, antibacterial properties, and the like, and the functional panels are made of various materials according to the purpose to be installed in the building.

As the functional panel as described above, EPS panels using expanded polystyrene (EPS) as an inner core material, and fire resistant panels using glass wool and mineral wool as inner core materials are typical.

The EPS panel has a light weight, low cost, easy handling and construction, and the fireproof panel has an excellent fire resistance and nonflammability.

In particular, in recent years, the regulations on the fireproof structure of buildings have been strengthened, and since the EPS panel has a high risk of spreading to a large fire when a fire occurs, the EPS panel is fireproof for the purpose of reducing human and material damage caused by a large fire. The use of panels is recommended.

The fireproof structure is a structure having a performance that can withstand fire for a predetermined time in the main structure (column, beam, wall, floor, roof, etc.) of the building, means a structure having a fireproof performance prescribed by the Ministry of Construction and Transportation.

1 is a perspective view showing the configuration of a fireproof panel according to the prior art, Figure 2 is a cross-sectional view showing a fireproof panel according to the prior art.

As shown in FIG. 1 or 2, the fireproof panel according to the prior art has a pair of metal plates 2 disposed to face each other and a core material 4 disposed between the pair of metal plates 2. And a fire resistant adhesive 6 applied to both sides of the core 4 such that the metal plate 2 is adhesively fixed to both sides of the core 4.

The pair of metal plates 2 is typically formed of a thin steel sheet.

The core 4 is formed of glass wool or mineral wool that is excellent in fire resistance and incombustibility.

Here, the core material (4) is a plate-shaped raw material formed of the glass wool or mineral wool to a predetermined thickness and then cut the refractory material (4A) cut from the raw material in the longitudinal direction between the pair of metal plate (2) A plurality is arranged and formed.

The thickness of the core material 4 may be changed according to the fireproof time required for the fireproof panel 1, but if the fireproof panel 1 is formed too thick, the actual square number of the building decreases and workability is poor during construction. Therefore, the glass wool or mineral wool is made of a core material 4 having a very high density.

That is, the core material 4 is formed of glass wool having a density of 70 kg / m 3 or more, or is formed of mineral wool having a density of 140 kg / m 3 or more.

When the core material 4 is formed of glass wool or mineral wool of high density in this way, the incombustibility and fire resistance of the core material 4 are improved to satisfy the desired fire resistance time without forming the thickness of the fireproof panel 1 too thick. It becomes possible.

In addition, the core material 4 is formed of a structure in which a plurality of fireproof materials 4A are disposed to be in contact with each other, and a contact surface of the fireproof material 4A is formed long in the thickness direction of the fireproof panel 1, A fire resistant adhesive 6 is applied to the contact surface of the fire resistant material 4A so that the plurality of fire resistant materials 4A are adhesively fixed.

On the other hand, at both ends of the fireproof panel 1, the connecting groove 10 and the connecting projection 12 is formed so that the connection between the fireproof panel 1 and the neighboring fireproof panel (1) when the construction, the connection is formed, the connection The riveting is performed at 300 mm intervals at the connecting portion of the fireproof panel 1 so that the strength of the portion where the groove 10 and the connecting protrusion 12 are connected is improved.

If the riveting is not performed at the connection portion of the fireproof panel 1, the metal plate 2 forming the connection portion of the fireproof panel 1 is thermally deformed due to a fire. The connection site of) is opened and separated so that the plurality of fire resistant panels 1 are collapsed arbitrarily.

In this way, the connection part of the fireproof panel 1 is subjected to riveting so as to prevent collapse due to heat deformation during a fire, thereby reinforcing the connection strength.

However, in the fireproof panel according to the related art, the pair of metal plates 2 are thinly formed, and the core material 4 is also formed of a material having a very low strength such as glass wool or mineral wool. ) Is very fragile, so there is a problem that is easily broken by an external impact.

In addition, when the core material 4 having a high density is used to reduce the thickness of the fire resistant panel 1 and to improve the fire resistance and the fire retardant performance, the unit cost of the core material 4 is increased, thereby increasing the cost of the fire resistant panel ( There is a problem that the price competitiveness of 1) is lowered.

In addition, the glass wool and the mineral wool, the moisture absorption due to the hygroscopic characteristics, the fire resistance and non-combustible performance is greatly reduced, the conventional fire-resistant panel (1) is a core material (4) between a pair of metal plate (2) ) Has a problem that the moisture is easily penetrated between the metal plate (2).

 If moisture penetrates into the interior of the fireproof panel 1 and the function of the core material 4 is lost, the fireproof structure of the building is destroyed, thereby increasing the risk of fire and incurring a replacement cost of the core material 4. There is a problem.

In addition, since the core material 4 is made of glass wool or mineral wool, fine particles of the glass wool or mineral wool are scattered to the surroundings during construction of the fireproof panel 1, thereby degrading workability, and the glass wool or mineral wool. Respiratory diseases or allergies are caused to workers due to fine particles of wool.

In addition, since the riveting is carried out at the site where the fireproof panel 1 is connected to the neighboring fireproof panel 1 when the fireproof panel 1 is constructed, the number of work steps during the construction of the fireproof panel 1 is increased. There is a problem that the property is lowered, and the unit cost rises due to the riveting process.

In addition, the plurality of fire resistant materials 4A are bonded by the fire resistant adhesive 6 and the metal plate 2 is attached and fixed to the core 2 by the fire resistant adhesive 6, but the fire resistant adhesive 6 Since there is a limit to increase the fire resistance of the fire resistance, the fire resistant adhesive 6 has a high risk of being deteriorated by high heat in case of fire, and due to the deterioration of the fire resistant adhesive 6, the metal plate 2 is peeled off or a plurality of fire resistant There is a problem that the material 4A is separated from each other.

The present invention has been made to solve the above problems, an object of the present invention is to coat the outer surface of the core material with a high-strength non-combustible material, the strength of the core material is reinforced to improve the durability and life of the fireproof panel, It is to provide a fireproof panel and a method of manufacturing the same that can improve the fireproof panel performance by increasing the fire resistance and non-combustible performance.

In addition, another object of the present invention is to form a structure in which the core is completely blocked from the outside by the non-combustible material, the penetration of moisture into the core is prevented to prevent degradation of the fire resistance due to moisture, dust of glass wool or mineral wool It is to provide a fireproof panel and a method of manufacturing the same that can be prevented to improve the safety.

In addition, another object of the present invention is to prevent the occurrence of dust during the construction of the fire-resistant panel is improved the working environment, the fire-retardant panel that can improve the workability by eliminating the riveting work carried out at the connection portion of the fire-resistant panel and It is to provide a method of manufacturing the same.

The fire resistant panel of the present invention for realizing the above object is a core material formed to a predetermined width and thickness, the metal plate mounted on both sides of the core material, the strength and fire resistance of the core material is reinforced and the core material and the metal plate It characterized in that it comprises a high-strength non-flammable coating material is coated on the outer surface of the core material to be welded fixed.

Here, the non-combustible coating material is formed of at least one material of magnesium powder and vermiculite powder, and is coated to seal the entire outer surface of the core material so that the core material can be blocked from the outside.

The core material is formed with a through hole so that a part of the non-combustible coating material can be hardened by penetration. The through hole is formed to penetrate in the thickness direction of the core material.

The metal plate is made of steel.

In addition, the core material is formed of any one of glass wool and glass wool (Mineral Wool), the core material is a glass wool having a density of any one of 48 ㎏ / ㎥ and 10 ㎏ / ㎥ Or mineral wool having a density of 100 kg / m 3.

Unlike the above, the core material may be formed of any one material of expanded polystyrene (EPS) and vacuum extruded polystyrene (Vacuum Extruding EPS).

On the other hand, the connecting means is formed at the end of such a fireproof panel to be connected to the end of the other fireproof panel.

The connecting means includes a connecting protrusion formed at one end of the fireproof panel and a connecting groove formed at the other end of the fireproof panel so that the connecting protrusion of the other fireproof panel is fitted.

Unlike the above, the connecting means comprises a connecting groove formed at an end of the fireproof panel, and a connecting member which is fitted at both ends of the connecting groove of the fireproof panel and the other fireproof panel.

On the other hand, the manufacturing method of the fireproof panel according to the present invention is a melting step of melting the non-flammable coating material formed of at least one material of magnesium powder and vermiculite powder, and coating to apply the melt of the non-combustible coating material to the outer surface of the core material And a welding step of welding and fixing the metal plate to both sides of the core material to which the non-combustible coating material is applied.

The manufacturing method of the fireproof panel further comprises a drilling step of forming a through-hole in the core material before the coating step.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

3 is a perspective view showing the configuration of a fireproof panel according to an embodiment of the present invention, Figure 4 is a cross-sectional view showing a fireproof panel according to an embodiment of the present invention, Figures 5a, 5b, 5c, 5d The state diagram of the connection structure of the fireproof panel according to an embodiment of the invention is shown.

As illustrated in FIG. 3 or 4, the fire resistant panel according to an embodiment of the present invention is disposed between a pair of metal plate 52 and a pair of metal plate 52 disposed to face each other. It comprises a core 54 and a high-strength non-flammable coating material 56 is coated on the outer surface of the core 54.

The metal plate 52 is formed of a thin steel sheet.

The metal plate 52 as described above is preferably formed with a separate plating layer or coating layer on the outer surface to improve aesthetics or non-combustibility.

That is, zinc plating is performed on the outer surface of the metal plate 52, and the surface of the zinc plating layer is coated with silicon polyester or fluorine. In this embodiment, a galvanized steel sheet having a thickness of 0.5 mm is used as the metal plate 52.

The core 54 is formed of any one material of glass wool and mineral wool having excellent fire resistance and nonflammability.

Here, since the core material 54 is improved in fire resistance and incombustibility by the non-flammable coating material 56, even if low-density glass wool or mineral wool is used, it satisfies the fire time prescribed by the building method.

That is, the core 54 is formed of glass wool having a density of any one of 48 kg / m 3 and 60 kg / m 3, or is formed of mineral wool having a density of 100 kg / m 3.

The core 54 is preferably formed on the outer surface by a fabric 58 woven from glass fiber so that fine particles of the glass wool or mineral wool do not scatter to the outside.

In addition, since the core 54 is sufficiently reinforced by the non-combustible coating 56, the raw material of glass wool or mineral wool can be used as the core 54 without any additional processing. Therefore, since the plurality of refractory materials cut after cutting the raw material to the required thickness for reinforcing the strength of the core as in the prior art is not bonded with an adhesive, not only the manufacturing process of the refractory panel 50 is simplified but also during the manufacturing operation. Workability is also improved.

Unlike the above, the core 54 may be formed of any one of a foamed polystyrene (EPS) and a vacuum extrusion polystyrene (Vacuum Extruding EPS).

The foamed polystyrene is a structural material commonly referred to as 'styrofoam', and has excellent sound insulation, sound insulation, heat insulation, low cost, and small specific gravity, and thus easy handling and construction.

The vacuum extruded polystyrene is a structural material having an independent bubble structure commonly referred to as 'Isopink', and is manufactured at a higher density than the expanded polystyrene, so that the soundproofing, the soundproofing, and the insulating property are better, as well as moisture resistance, water resistance, and compression. There is an advantage of further strength.

Such foamed polystyrene and vacuum-extruded polystyrene are non-fireproof materials that are very poor in fire resistance and non-flammable performance, but when manufactured in a structure completely covered by the non-flammable coating material 56 as in the present invention, a certain level of fire resistance and non-flammability This ensures that the building can be used for buildings where the fire resistance regulations are not strictly applied.

The non-combustible coating material 56 is coated to seal the entire outer surface of the core material 54 to a predetermined thickness, is formed of at least one material of magnesium powder and vermiculite powder.

That is, the non-combustible coating material 56 is a material having excellent strength, fire resistance, and non-combustible performance. The strength, fire resistance, and non-combustibility of the core material 54 are not only improved, but the core material 54 is isolated from the outside to penetrate moisture. And dust generation is completely blocked.

The non-combustible coating material 56 as described above is applied to the outer surface of the core material 54 in a molten state and then hardened by cooling, and also serves to weld and fix the metal plate 52 to both sides of the core material 54. Will be performed.

On the other hand, the connecting means is formed at the end of the fire-resistant panel 50 configured as described above so as to be connected to the end of the other fire-resistant panel 50 'neighboring during construction, an embodiment of the connecting means shown in Figures 4 to 5d When described in detail with reference to as follows.

As shown in Figure 4 and 5a, the first embodiment of the connecting means is a connecting projection 61 formed on one side of the end portion of the fire panel 50, and the connecting projection of the other fireproof panel (50 ') 61 ') is formed of a connection groove 60 formed at the other end of the end portion of the fire resistant panel 50 so as to be connected to each other.

Since the connection groove 60 and the connection protrusion 61 as described above are formed by the metal plate 52 and the non-flammable coating material 56, even if the flame is propagated between the connection groove 60 and the connection protrusion 61. The core 54 is not directly exposed to the flame, and the strength of the connection groove 60 and the connection protrusion 61 is sufficiently secured by the metal plate 52 and the non-flammable coating material 56.

As shown in FIG. 5B, the second embodiment of the connecting means includes a connecting protrusion 63 and a connecting groove 62 formed at both ends of the fireproof panel 50, respectively, and the connecting protrusion 63. And the connection groove 62 are alternately disposed at one end and the other end of the fireproof panel 50, and the other configuration is the same as in Figs. 4 and 5a.

Therefore, the connection protrusion 63 and the connection groove 62 formed at the other end of the fireproof panel 50 are connected to the groove 62 'and the connection protrusion 63' formed at one end of the other fireproof panel 50 '. Connected with

As shown in FIG. 5C, the third embodiment of the connecting means includes connecting grooves 64 formed at both ends of the end portion of the fireproof panel 50, and a fireproof panel 50 ′ different from the fireproof panel 50. Both ends of the connecting groove 64 'is fitted into the coupling member 65 is coupled, the other configuration is the same as the configuration of Figs. 4 and 5a.

The connecting member 65 is a tubular member formed of a material having excellent incombustibility and fire resistance. The connecting member 65 is formed to have the same width as that of the fire resistant panel 50, and is different from the fire resistant panel 50. It is formed with the same width and thickness as the connecting grooves 64, 64 '.

As shown in FIG. 5D, the fourth embodiment of the connecting means includes connecting grooves 66 formed at both ends of the end portion of the fireproof panel 50, and mounting grooves mounted at one side of the connecting groove 66. 69 are formed at both ends of the coupling guide 68 and the coupling grooves 69 and 69 'formed in the connection guides 68 and 68' of the fireproof panel 50 and the other fireproof panel 50 '. It is made of a connecting member 67 to be coupled, and the other configuration is the same as in Figs. 4 and 5a.

The connecting member 65 is a rod-shaped member formed of a material having excellent incombustibility and fire resistance. The connecting member 65 is formed to have the same width as that of the connecting guide 68, and connects the fireproof panel 50 to another fireproof panel 50 '. It is formed to the same width and thickness as the coupling grooves 69 and 69 'formed in the guides 68 and 68'.

The other side of the connection guide 68 is fixed to the connection groove 66 of the fire panel 50, the bar is preferably formed of the same material as any one of the metal plate 52 and the non-flammable coating material (56). .

Hereinafter, in the present embodiment, the connecting means of the fireproof panel 50 is limited to the connection groove 60 and the connecting protrusion 61 shown in FIGS. 4 and 5A.

Looking at the manufacturing method and the operation effect of the fireproof panel according to an embodiment of the present invention configured as described above are as follows.

First, the non-flammable coating material 56 formed of at least one of magnesium powder and vermiculite powder is melted and then evenly applied to the entire outer surface of the core material 54.

Since the core material 54 is completely blocked from the outside air by the non-flammable coating material 56, moisture does not penetrate into the core material 54, thereby preventing the loss of the function of the core material 54 due to moisture. Dust is not generated to the outside of the core material 54 is prevented deterioration of the working environment due to dust.

In particular, since various diseases such as respiratory diseases and allergies due to dust are prevented during manufacture and construction of the fire resistant panel 50, safety and workability of the fire resistant panel 50 are improved.

When the molten non-combustible coating material 56 is applied to the outer surface of the core material 54, the metal plate 52 is welded to both sides of the core material 54, respectively. That is, as the non-flammable coating material 56 is hardened in the molten state, the metal plate 52 is firmly attached to both sides of the core material 54 by the non-flammable coating material 56.

Therefore, when the metal plate 52 is welded to the outer surface of the core 54 by the non-flammable coating material 56, the refractory adhesive for attaching the conventional metal plate and the core material is omitted, thereby reducing the unit cost, fire-resistant in case of fire Fire resistance and deterioration of durability due to deterioration of the adhesive are also prevented at the source.

On the other hand, the fireproof panel 50 according to the present embodiment is a process in which the non-flammable coating material 56 is coated on the outer surface of the core material 54, and the outer surface of the core material 54 to which the non-combustible coating material 56 is applied Since the process of attaching the metal plate 52 can be carried out in one process in a single device, production automation of the fireproof panel 50 is easily realized, and the number of processes during manufacture is reduced.

On the other hand, the process of coating the non-flammable coating material 56 on the outer surface of the core material 54, and the process of mounting the metal plate 52 on both sides of the core material 54 coated with the non-flammable coating material 56 Of course, they can be carried out at different times by different companies. That is, when the primary company manufactures the core material 54 coated with the non-flammable coating agent 56, the secondary company that purchases the core material 54 attaches the metal plate 52 to both sides of the core material 54 to provide fire resistance. By manufacturing the panel 50, division of labor and specialization between companies can be realized.

In the fireproof panel 50 manufactured as described above, the strength, the fire resistance, the non-combustible performance, and the like of the core 54 are reinforced by the non-flammable coating material 56.

Here, when the strength of the core material 54 is reinforced by the non-flammable coating material 56, since the fire resistant panel 50 is not easily broken or deformed by an external impact, the durability of the fire resistant panel 50 is improved. The service life is extended and a separate reinforcing structure for strength reinforcement is unnecessary as in the prior art.

That is, in the related art, the core material of the core material is supplemented by cutting the raw material of the core material to a predetermined thickness and then arranging a plurality of cut raw materials between the metal plate materials. Even if the raw material is used as it is, the strength is sufficiently secured by the non-flammable coating material 56. Therefore, since the work for processing the core 54 is omitted during the manufacture of the fire-resistant panel 50, the work maneuver is reduced, workability and productivity is increased, the raw material of the core 54 is used as it is, manufacturing convenience This is improved.

In addition, even if the core material 54 is formed of low-density glass wool and mineral wool, since the fire resistance and the non-combustible performance of the core material 54 is reinforced by the non-flammable coating material 56, the fireproof panel 50 is It satisfies the fire resistance performance of the building code, but the manufacturing cost is greatly reduced.

As described above, since the strength and fire resistance of the fire resistant panel 50 is greatly improved, the thickness of the fire resistant panel 50 is the same as that of the conventional fire resistant panel, or the thickness thereof is the same as that of the conventional fire resistant panel. It is also possible.

When the thickness of the fire resistant panel 50 is made thin, the installation space of the fire resistant panel 50 is reduced, so that the actual square number of the building is increased, and when the performance of the fire resistant panel 50 is increased, the fire resistance regulation of the recently strengthened building It fully satisfies and the merchandise is improved.

On the other hand, when the fireproof panel 50 manufactured as described above in the building, the connecting projection 61 formed on one side of the end portion of the fireproof panel 50 is connected to the groove 60 'of the other fireproof panel 50' The connecting projection 61 'of another fireproof panel 50' is connected to the connecting groove 60 formed at the other end of the fireproof panel 50.

In the same manner as described above, a plurality of fire resistant panels 50 and 50 'are constructed at desired portions of the building.

Since the connection protrusion 61 and the connection groove 60 of the fireproof panel 50 are sufficiently secured by the non-flammable coating material 56, the connection portions of the fireproof panels 50 and 50 'are not the same as in the related art. Otherwise riveting is not performed.

Because the connection part of the fireproof panels 50, 50 'is minimized thermal deformation by the non-combustible coating material 56 and the metal plate 52 in the event of a fire of the building not only reduces the risk of collapse, but also the fireproof This is because the flame is blocked by the non-combustible coating material 56 so that the core material 54 does not burn directly even when the connection portion of the panels 50 and 50 'is opened.

6 is a cut-away perspective view showing the configuration of a fireproof panel according to another embodiment of the present invention, Figure 7 is a cross-sectional view showing a fireproof panel according to another embodiment of the present invention, Figure 8 is a line AA of FIG. 9A, 9B, 9C, 9D and 9E are diagrams illustrating various shapes of through-holes of a fireproof panel according to another exemplary embodiment of the present invention.

For reference, the same reference numerals are given to the same or similar components as those of the exemplary embodiment, and detailed description thereof will be omitted.

6 or 7, the fireproof panel according to another embodiment of the present invention, the through-hole 70 is formed in the core material 54, the non-combustible coating material 56 is coated on both sides of the core material 54 Supported portion 71 is penetrated and hardened inside the through-hole 70 so that the parts 56A and 56B can be supported by each other, and other configurations are configured in the same manner as in the above embodiment.

The through hole 70 is formed to penetrate in the thickness direction of the core material 54, and the non-flammable coating material 56 is a portion (56A, 56B) coated on both sides of the core material 54 is the support portion ( 71) is connected and supported.

Therefore, since the non-flammable coating material 56 is a structure in which the portions 56A and 56B coated on both side surfaces of the core material 54 are supported by the support parts 71 formed inside the plurality of through holes 70. The overall strength of the non-combustible coating material 56 is greatly increased so that the fire resistant panel 51 can be used as a structural material for buildings.

Meanwhile, the through hole of the present invention is formed in various shapes according to the design conditions of the fire resistant panel 51, as shown in FIGS.

That is, a plurality of through holes are formed in the core material 54 in any one cross-sectional shape of a circle, a polygon, and a cross, and in FIG. 6 to FIG. 8, a core material having a through hole 70 and a support part 71 having a circular cross section. A 54 is shown, and a core 54 having a through hole 72 and a support 73 of a cross section is shown in FIG. 9A.

As described above, the through holes 70 and 72 are formed in the core 54 so as to be spaced apart at regular intervals, and the plurality of through holes 70 and 72 are spaced 250 mm in the width direction of the core 54 and 300 mm in the longitudinal direction. It is preferably formed spaced apart.

In addition, a plurality of through-holes are formed in the cross section of any one of a straight line and a comb-shape in the core 54, and in FIG. 9B, a core 54 having a through-hole 74 and a support portion 75 having a straight cross section is provided. 9c shows a core 54 having a through hole 76 and a support 77 of a comb-shaped cross section.

As described above, the through holes 74 and 76 are formed in the core 54 so as to be spaced apart from each other at regular intervals. The through holes 74 and 76 are formed in the width direction of the core 54 and extend in the longitudinal direction of the core 54. The plurality is preferably formed to be spaced apart at equal intervals.

In addition, the through hole is formed in any one cross-sectional shape of the lattice shape and the honeycomb shape in the core material 54, the core material 54 having the through hole 78 and the support portion 79 of the lattice cross section 9E shows a core 54 having a through-hole 80 and a support 82 of a honeycomb cross section.

The through holes 78 and 80 as described above are uniformly formed over the entire surface of the core 54.

Therefore, the strength reinforcing effect of the core material 54 by the through holes 78 and 80 and the support parts 79 and 80 is increased, and the non-combustible coating material 56 provided with the support parts 79 and 82 is provided. Since the plurality of cores 54 are arranged in a structure in which the plurality of cores 54 are separated from each other, the plurality of cores 54 are independently protected to improve durability of the fire resistant panel 51.

For example, when a portion of the non-combustible coating material 56 is broken, moisture penetrates into the core material 54 adjacent to the damaged portion of the non-combustible coating material 56 to reduce fire resistance or cause a fire to occur. While propagated and combusted, the core 54, which is not adjacent to the broken portion of the non-combustible coating 56, is blocked from penetration of moisture or propagation of flame. As described above, even if a part of the non-flammable coating agent 56 is broken, the fire resistant panel 51 has a reduced fire resistance performance and a non-flammable performance, thereby improving product reliability.

Hereinafter, in this embodiment, the fireproof panel 51 will be limited to having a through hole 70 and a support portion 71 having a circular cross section shown in FIGS. 6 to 8.

On the other hand, in the manufacturing method of the fireproof panel according to another embodiment of the present invention configured as described above a plurality of through-holes 70 are formed in the core material 54, formed of at least one material of magnesium powder and vermiculite powder The nonflammable coating material 56 is melted.

The melt of the non-flammable coating material 56 is applied to the entire outer surface of the core material 54, and the metal plate 52 is attached to both sides of the core material 54 on which the melt of the non-flammable coating material 56 is applied. As the non-flammable coating material 56 is solidified, the core 54 and the metal plate 52 are welded and fixed firmly by the non-flammable coating material 56.

At this time, a portion of the non-flammable coating material 56 applied to both sides of the core material 54 is penetrated and hardened in a molten state inside the through hole 70 to form the support portion 71 of the non-flammable coating material 56. do.

When the support portions 71 are formed inside the plurality of through holes 70, the structural strength of the fire resistant panel 51 is further increased by the non-combustible coating material 56.

That is, since the interior of the non-flammable coating material 56 is connected to each other by the plurality of support parts 71, the structure of the fire resistant panel 51 is due to the dispersion effect of the impact and stress applied to the fire resistant panel 51. Use strength is increased.

On the other hand, the fireproof panel 51 according to the present embodiment is a process of drilling a plurality of through-hole 70 in the core material 54, the process of coating the non-combustible coating material 56 on the outer surface of the core material 54 And, the process of attaching the metal plate 52 to the outer surface of the core material 54 to which the non-flammable coating material 56 is applied is carried out in one step by a single device.

Therefore, not only the production automation of the fireproof panel 51 is easily realized, but also the number of processes during manufacturing is reduced.

As described above, the fire resistant panel according to the present invention and a method of manufacturing the same have been described with reference to the illustrated drawings. Of course, variations are possible.

The fireproof panel according to the present invention configured as described above is coated with a high-strength non-flammable coating on the outer surface of the core material, the strength of the core material is reinforced to improve the durability and life of the fireproof panel, the fire resistance performance and the non-combustible performance of the core material is improved The merchandise of the fireproof panel is improved.

In addition, since the core material is completely blocked from the outside by the non-combustible coating material, the penetration of moisture into the core material from the outside of the fireproof panel is blocked, there is an advantage that the loss of the core material due to moisture is prevented.

In addition, when glass wool or mineral wool is used as the core material, since the fine particles of glass wool or mineral wool are prevented from scattering to the outside from the core material, deterioration of the working environment due to dust is prevented, and worker's disease due to dust This is prevented and there is an advantage that the safety is improved.

In addition, when the non-combustible performance and the fire resistance of the core are increased by the non-combustible coating material, the core material formed of low density glass wool or mineral wool can be used, thereby reducing the manufacturing cost of the fire resistant panel, and if necessary, reducing the fire resistance performance of the core. The fireproof panel is manufactured to a thickness, which has the advantage that the actual floor area of the building increases.

In addition, since the strength of the core material is reinforced by the non-combustible coating material, and the fire resistance and fire resistance performance of the core material are increased, even if the non-fireproof foam polystyrene or vacuum extruded polystyrene is used as the core material, the fire resistance and the non-flammability of the fire resistant panel are secured. There is an advantage.

In addition, since the through-hole is formed in the core material in the non-combustible coating intrusion hardening, there is an advantage that the structural strength of the fire-resistant panel is greatly improved by the support of the non-combustible coating material formed inside the through hole.

In addition, since the structural strength of the fireproof panel is improved by the non-combustible coating material, unlike the conventional material, since the core material can be used as it is without additional reinforcing process, there is an advantage that the fireproof panel is easily manufactured and the number of working processes is also reduced.

In addition, when the core material and the metal plate is welded by the non-combustible coating as described above, and the core material is used as it is, the cost saving is realized because expensive fireproof adhesive is not used in the manufacture of the fireproof panel, and deterioration of the fireproof adhesive when a fire occurs Due to this, there is an advantage in that performance degradation and breakage of the fireproof panel are prevented.

In addition, during the construction of the fireproof panel, a portion where the plurality of fireproof panels are connected is reinforced by a non-flammable coating material, and in case of a fire, the connection part of the fireproof panel is thermally deformed and collapsed is prevented, and the flame is connected to the fireproof panel. This propagation has the advantage of preventing the phenomenon that the core material is burned.

In addition, since the process of applying the non-flammable coating material to the core material and the process of adhering the metal plate to the core material coated with the non-flammable coating agent may be performed by separate companies, there is an advantage in that division of labor and specialization are implemented in the manufacture of the fireproof panel. .
