The present invention relates to a manufacturing apparatus of a prefabricated air panel used for construction, and more particularly, to manufacture a prefabricated panel for building a consistently and quickly in a continuous and consistently excellent excellent firewall function by flame protection and good thermal insulation and soundproofing at a lower price It relates to an apparatus for manufacturing a prefabricated air panel for construction that can be provided to.

In general, prefabricated panels for building are configured to be continuously assembled for the interior and exterior walls or partitions of the building, for this purpose, one end is formed with a coupling recess and the other end is formed with a coupling protrusion to be engaged with each other. The coupling recesses and the coupling protrusions are formed by bending the upper / lower plates (meaning the inner and outer plates: hereinafter referred to as upper / lower plates) made of mostly steel sheets.

In addition, between the upper and lower plates, a filler having heat insulation / thermal insulation or nonflammable / flame retardancy is put to impart heat insulation / thermal insulation or impart nonflammability / flame retardancy. However, the use of non-flammable / flame-retardant materials such as glass wool or mineral wool, which are resistant to fire as a filling material filled between the upper and lower plates, has the effect of delaying the generation of flames in case of fire, but once the fire is fired from either side, Because the flames spread easily, the firewall function is reduced, and the panel itself is usually warped so that the strength of the panel itself is considerably reduced.

In view of this, panels filled with fillers filled between the upper and lower plates have been developed by repeatedly stacking insulation / heat insulating members and non-flammable / flame retardant members, but such a degree does not improve the strength of the panel. Most of them must be made in continuous manufacturing equipment to achieve cost reduction by mass production.

However, in the conventional manufacturing apparatus, the process of continuously stacking the insulation / heat insulating member or the non-flammable / flame retardant member in the line between the upper plate and the lower plate is difficult and takes a long time, so the productivity is not so good.

In the production line where the upper and lower plates are joined together, the foamed urethane liquid is put between the upper and lower plates, and then the foamed filler is filled between the upper and lower plates by curing the injected filler before the panel is transferred to the cutting line. Produce and sell.

However, since the panel is filled with the foam filler in the space between the upper plate and the lower plate, the strength of the panel is improved to some extent, but it is not always said that the thermal insulation insulation or sound insulation is very good, and the upper / lower plate in case of fire occurs. When heated, the entire foamable filler inside was easily engulfed in flames, which prevented the firewall from improving.

The present invention was developed in view of the above-described conventional problems, and an object of the present invention is to put an air plate having an air hole between the upper and lower plate members made of steel sheets, and between the air plate and the upper and lower plates. The present invention provides a manufacturing apparatus for a prefabricated air panel for building which can continuously manufacture a three-ply structured panel having a foamable heat-resistant filler thereon more easily.

In the drawings, reference numeral 140 is a foamed filler.

The process of manufacturing the panel 100 by the manufacturing apparatus of the present invention formed as described above will be described in detail for each process as follows.

First process (material supply and molding process)

In the upper plate material supply unit 10 formed of the uncoiler and the coil car of the first line, the upper plate material is supplied to the upper plate roll forming unit 11 to form the upper plate 110 in a predetermined shape and then sent to the heating oven 40.

In addition, the lower plate material supply unit 20 formed of the uncoiler and the coil car of the second bottom line sends the lower plate material to the lower plate roll forming unit 21 to form the lower plate 120 in a predetermined shape, and then sends the heating plate 40 to the heating oven 40. .

In addition, the air plate material supply unit 30 including the uncoiler and the coil car of the third line located between the first line and the second line sends the air plate material to the air plate roll forming unit 31 so that the air hole 131 The air plate 130 is formed in a predetermined shape to be provided, and then sent to the heating oven 40.

At this time, the third line, if necessary, that is, the type in which one air plate 130 is installed is installed in the singular, and the type in which two or more air plates 130 are installed in plurality is installed by the air plate 130 To be supplied.

In addition, when the air plate 130 is formed in the air plate roll forming part 31, the material is bent in a zigzag form as shown in FIGS. 4 and 5 so that the air hole 131 is completely formed by itself. Send to the heating oven (40).

In addition, when the air hole 131 of the air plate 130 is not completely molded in the air plate roll forming unit 31 and is bent and molded in an open state, one end of the air plate 130 is opened in the taping unit 50 as shown in FIG. 6. To cover the cover 51 so that the air hole 131 is formed and then supplied to the heating oven (40).

Second process (heating process of molded material)

As described above, the upper plate 110, the air plate 130, and the lower plate 120 supplied to the heating oven 40 are heated to a predetermined temperature in a predetermined shape. Here, the heating of the upper plate 110, the air plate 130 and the lower plate 120 to a predetermined temperature is to facilitate the foaming of the foam filler 140 is injected in the next process.

3rd process (injection of foamable filler liquid)

Filler liquid injection portion (60a) (60b) when the upper plate 110, the air plate 130 and the lower plate 120 passing through the heating oven 40 passes in an overlapping state while maintaining a predetermined interval from each other As in 3, the foaming filler fluid is injected between the upper plate 110 and the air plate 130 and between the air plate 130 and the lower plate 120.

4th process (tapping and foam molding process of panel side)

When the panel 100 into which the foamable filler liquid is injected enters the foam curing unit 70, the upper plate 110 and the lower plate 120 constituting the panel 100 are disposed between upper and lower tracks 71a and 71b. Both tracks 82 of the side tracks 80 are positioned and guided by attaching tapes 84, which enter between the front end rollers 81a and the side surfaces of the panel 100, in close contact with the sides of the panel 100. In addition, the tape 100 is continuously pressed while the panel 100 passes completely through the side track 80 so that the taping state for blocking the side opening of the panel 100 is good.

In addition, both tracks 82 of the side tracks 80 are provided with an air plate placed in the middle of the upper plate 110 and the lower plate 120 when the magnet 83 is installed at a central portion in contact with the side surface of the panel 100. Since the 130 is moved forward in a state where the position is fixed by magnetic force, the distance between the upper plate 110 and the lower plate 120 can be maintained very well.

In addition, since the foam filling liquid injected in this state is foamed, the foaming space of the filler 140 is sufficiently secured, and the foaming is performed satisfactorily. At this time, both side openings of the panel 100 are sealed with a tape 84. Since the state of maintaining the foaming of the filling liquid is maintained there is no fear that the filler 140 is leaked to the outside through the side opening of the panel 100.

Therefore, the filling material 140 that is foamed is filled between the upper plate 110 and the air plate 130 constituting the panel 100 and the air plate 130 and the upper plate 110 without leaking to the outside. While the appearance is clean, the filling state of the filler 140 becomes good, and the foamable filler 140 is completely cured while passing through the foam curing unit 70 in this state.

5th process (cutting and cooling process)

In the foam molding unit, the foaming and molding of the filler 140 is completed, and the panel 100 having the upper plate 110, the air plate 130, and the lower plate 120 integrated is transferred to the panel cutter 90 to have a predetermined length ( After cutting according to the length of the product set in accordance with the intended use) is transferred to the panel cooling unit 91 which is a cooling system is cooled to room temperature.

6th process (lamination and packaging process)

After being transferred to the stacking unit by the auto stacker system and stacked at a predetermined height, the stacker 93 is transported and packaged as it is, and the manufacturing and packaging state of the panel 100 for shipment is completed.

In the present invention, the air plate 130 between the upper and lower plates in the material supply and molding process of the first process is brought into close contact with the inner surface of either one of the upper plate 110 and the lower plate 120 as shown in FIG. 7A. The foaming filler liquid injection process of the third process may be performed in the space between the plate 130 and the opposite panel, or as shown in FIG. 7B, one more air line 130 supply line is installed to form the upper plate 110 and the upper plate 110. The air plate 130 may be supplied to all of the inner surfaces of the lower plate 120 to be in close contact with each other, and the foaming filler liquid may be injected therebetween.

As described above, the panel manufactured according to the present invention inserts an air plate having air holes between upper and lower plates made of steel sheet, and foams and forms a foamed heat-resistant filler therebetween, so that a fire occurs on either side. Even if a flame occurs in the filler, the opposite side of the filler is not easily spread by the air plate provided with the air hole, and thus has excellent firewall function to evacuate in the meantime.

In addition, since the air plate made of a metal sheet is further installed in the foam filling filled between the upper and lower plates, the strength is better than that of the panel filled with the conventional foam filling, and the sound insulation and insulation insulation effect is increased.

According to the present invention, since the upper / lower plate and the air plate form a three-ply, the prefabricated panel for filling and filling the foam filler therebetween can be manufactured more quickly and easily in a continuous manner, so that mass production is possible and the production cost is lowered. You can do it.
