METHOD FOR MANUFACTURING PARTITION PANEL FOR ARCHITECTURE AND COMPOSITION PANEL FOR ARCHITECTURE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a partition panel for a building and a partition panel for a building, in which, in order to manufacture a partition panel for a building used as a partition or a door panel in an internal space environment of a building requiring water- A hot melt adhesive is applied in a heated and melted state through a coating roll rotating on a flat part of the core board to sequentially laminate the finishing materials and cure And more particularly, to a method for manufacturing a partition panel for a building and a partition panel for a building, which are configured to provide a better quality in terms of the beauty of the surface of a partition panel for construction and the mechanical properties as compared with the conventional woodworking adhesive.

Architectural partition panels are used in a variety of architectural interiors, such as for partitioning individual spaces from a building's internal space, or for forming partitions or doors in a toilet.

FIG. 1 is a perspective view showing a partition formed in a toilet using a partition panel for a building, FIG. 2 is a perspective view showing an example of a composite panel in a conventional building partition panel, and FIG. Sectional view.

As shown in FIGS. 1 to 3, an example of a partition panel 10 used in a conventional toilet is constructed by attaching a sheet-like finish material 15 to both sides of a core board 11.

The core board 11 may be made of a core board, a particle board, a synthetic resin panel, an aluminum sheet, a urethane board, a resin impregnation board, or the like, in order to provide a predetermined mechanical property (e.g., strength, resistance to deformation, durability, Reinforcing plate, plywood, medium-density fiberboard, etc. are used.

Further, in order to impart flame retardancy to a fire in consideration of the nature of use environment, i.e., the inner space of the building, and to impart waterproofness against moisture deformation due to long-term use in a humid environment such as a toilet, A melamine-impregnated paper such as melamine-impregnated paper (HPM) is used.

Preferably, frame members 13 having flame retardancy and / or waterproof properties are attached to the upper, lower, left, and right edges of the core board 11 to prevent moisture from penetrating through the rims of the partition panel for building, . ≪ / RTI > As such a frame member 13, for example, a compact panel product which is marketed under the trade name of " Lamis " is used, and a plurality of coupling grooves 11a and a plurality of coupling projections 13a are assembled together to increase a coupling force .

However, in the conventional partitioning panel for construction, in the process of attaching the finishing material 15 provided on both sides of the core board 11 with the high density melamine impregnated paper (HPM), a general woodworking adhesive (a mixed form of an aqueous binder for woodworking and a hardening agent In the case of the woodworking adhesive, since the thickness of the adhesive layer (reference numeral 19 in Figs. 4 to 6) is thin and the viscosity is low, the surface of the core board 11 has fine surface defects, steps, micro bending, In this case, adhesion of such portions is not completely achieved, and adhesion of pores, voids, and the like occurs in some cases (see F in FIG. 4). Further, in the case of the adhesive for woodworking, the bond is evaporated in the bonding process, and the peeling phenomenon of the partial finishing material 15 after bonding is caused.

Further, in a more severe case, such surface defects, level differences, fine bending, warping and the like may be observed in the naked eye of the user in the final finishing state in which the finishing material 15 is attached, which may deteriorate the appearance, (See F in Fig. 5).

On the other hand, in the case of the toilet door, since the size (for example, 1800 * 600 mm) of the core board 11 is relatively small, a piece of the finishing material 15 prepared in the commercial product size is cut to an appropriate size, However, in the case of a toilet wall partition, the size (for example, 1800 * 1600 mm) is relatively large, so that it is impossible to attach the entire area to a single finishing material 15 prepared in a commercial product size. The finishing material 15 may be subsequently attached.

However, in the case of using a conventional general woodworking adhesive in order to subsequently attach the two or more sheets of the finishing material 15, fine surface defects or steps present on the surface of the core board 11 may cause a problem, (See Fig. 6F). [0051] As shown in Fig.

When the partition member 13 is joined to the upper, lower, left, and right edges of the core board 11 as described above, a partition panel for a building is manufactured. The above-mentioned problems have also arisen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a method of manufacturing a partition panel for a building, which is used as a partition or door panel in an internal space environment of a building requiring waterproofing and flame resistance. A typical example of an environment requiring waterproofing and flame resistance is an environment used as a partition wall and a toilet door in a toilet. In the case of a toilet, a predetermined flame retardancy is required according to the environmental conditions inside the building in accordance with the building regulations, and water resistance is particularly required depending on environmental characteristics such as being easily exposed to moisture and moisture.

In order to provide a partition panel with waterproof property and flame retardancy, a method for manufacturing a partition panel for a building according to the present invention comprises preparing a square core board prepared by cutting a base material for a core board to a required size, (1) and a second flat surface portion, wherein the first and second finishing materials are made of a high-density melamine impregnated paper (HPM). In particular, as a bonding method for adhering the first and second finishing materials, a moisture- The hot-melt adhesive is applied in a heated molten state so as to be laminated so as to have a thickness of preferably 80 to 120 탆. This bonding method provides better quality in terms of the beauty of the surface of the partition panel for construction and the mechanical properties compared to the conventional woodworking adhesive.

Particularly, since the moisture-curing polyurethane hot-melt adhesive does not merely provide a simple adhesive function unlike the adhesive for woodworking after forming the cured layer to a thickness of 80 탆 or more, it plays a role of one structural layer providing its own strength and hardness The mechanical properties (strength, hardness, durability) of the entire partition panel are improved.

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

FIG. 7 is a flowchart illustrating a method of manufacturing a partition panel for a building according to an embodiment of the present invention. FIG. 8 is a schematic view illustrating a process of preparing a square core board according to an embodiment of the present invention. FIG. 10 is a schematic view showing a process of attaching a finishing material on a flat portion of a core board according to an embodiment of the present invention. FIG. 10 is a schematic view illustrating a process of applying a hot melt adhesive in a heating and melting state according to an embodiment.

First, a base material 110R for a core board made of any one of a core board, a particle board, a synthetic resin panel, aluminum, urethane, a resin impregnated board, a plywood board and a medium density board is cut into a required size, 110 are prepared (S100). Such cutting can be accomplished by using a general sawing rotary saw or by using a CNC milling machine for woodworking.

Then, the hot-melt adhesive 60 is applied in a heated and melted state through the application roll 50 rotating on the first flat surface portion 110-1 of the core board 110 while the core board 110 is being conveyed (S200). Preferably, the hot-melt adhesive is a moisture-curing polyurethane hot-melt adhesive, and the hot-melt adhesive is applied to a thickness of 80 to 120 μm. When a conventional hot-melt adhesive is applied, it is general that the coating thickness is not thicker than 60 탆. However, when applying a hot-melt adhesive for the purpose of adhering a high-density melamine impregnated paper (HPM) to form a partition panel for a building, the inventor has found that forming a coating thickness at a thickness of 80 [ And that it is desirable for ensuring the quality of the surface and the like. However, considering that the hot melt adhesive is excessively used and the thickness is excessively increased, there is no significant difference in securing the required adhesive strength and mechanical properties after curing even if the coating thickness is 120 탆 or more, the coating thickness of the hot melt adhesive is 80 to 120 탆 Of the total. If necessary, the coating thickness of the hot-melt adhesive may be formed to be thicker than 120 탆, and the present invention does not exclude this.

The hot-melt adhesive is an adhesive made by using a thermoplastic resin as a main component without using water or a solvent. The adhesive powder of the pellet type is melted at a high temperature to form a liquid, which is then applied to the adherend, Hot melt adhesive. The hot-melt adhesive is classified into EVA, PE, PP, SIS, polyester, polyamide, and polyurethane depending on the type of the base resin.

In the present embodiment, a moisture-curing polyurethane hot-melt adhesive is preferably used. The moisture-curing polyurethane hot-melt adhesive generally comprises a urethane prepolymer having an isocyanate group as a main component, and is solid at room temperature. When the adhesive is applied to an adherend by heating and melting, the adhesive strength is firstly exhibited while being cooled. The reaction between the water and the isocyanate groups at the ends in the air and on the surface of the adherend gradually progresses to cause crosslinking, thereby increasing the adhesive strength. The moisture-curing polyurethane hot-melt adhesive used in the present embodiment includes, for example, 30 to 50% of a polyester / isocyanate prepolymer as a main component, and has a temperature of 110 to 130 ° C (a temperature at which a coating operation can be performed in a molten state) It is preferable to use a material having a viscosity of about 40,000 cps at 120 DEG C for 3 minutes for a working time (time in which the adhesive work can be performed in a molten state).

Since the partition panel of the present embodiment is used in an environment such as a bathroom having a lot of moisture and moisture as described above, if a moisture-curing polyurethane hot-melt adhesive is used as an adhesive, The advantage is that it can be obtained.

In the present embodiment, the hot-melt adhesive 60 is preferably applied using a roll coater. 9, molten hot-melt adhesive 60 is supplied to a roll coater through a supply unit (not shown) and supplied and stored between the metering roll 52 and the application roll 50, The metering roll 52 and the application roll 50 are rotated in the direction of the arrow with the core board 110 being transported in the right direction on the portion 56 so that an appropriate amount of hot melt adhesive 60 is applied to the core board And is applied over the entire area. Reference numeral 54 is an auxiliary roll used for conveying the core board or applying the hot melt adhesive to the lower side of the core board at the same time.

Next, a first finishing material 130-1 composed of a high density melamine impregnated paper (HPM) is attached on the first flat surface portion 110-1 of the core board 110 on which the hot melt adhesive 60 is laminated (S300 ). The high density melamine impregnated paper (HPM) uses commercial products having a thickness of 0.8 to 3 mm, and these commercial products are provided by the manufacturer, for example, in the size of 1220 * 2440 mm, and cut to the size of the core board Thereby preparing an attachment size.

The attachment of the finishing material may be accomplished, for example, by applying a high-density melamine impregnated paper (HPM) of appropriate size onto the first flat surface portion 110-1 of the core board 110 on which the hot-melt adhesive 60 is laminated, And then the core board with the finishing material attached thereto is passed through a general roll press apparatus such as that shown in Fig. 10, as described above. The transfer from the roll coater to the roll press can be accomplished by conventional rail-type transfer equipment. Reference numerals 72 and 74 denote upper and lower pressure rolls of the roll press apparatus, respectively.

Next, a predetermined curing condition is applied to the hot melt adhesive 60 to bond the first finish material 130-1 to the first plane portion 110-1 (S400). The curing conditions may be provided by the desired cooling environment (curable temperature and time) over which the curing of the adhesive may be effected.

Next, the hot-melt adhesive 60 is heated and melted through the application roll 50 rotating on the second flat surface portion 110-2 of the core board 110 while the core board 110 is being transported in an inverted state (S500). At this time, preferably, the hot-melt adhesive is applied so as to have a thickness of 80 to 120 탆.

Next, a second finishing material 130-2 composed of a high density melamine impregnated paper (HPM) is attached on the second flat surface portion 110-2 of the core board 110 on which the hot melt adhesive 60 is laminated (S600 ).

Finally, a predetermined curing condition is applied to the hot melt adhesive 60 to bond the second finishing material 130-2 onto the second flat surface portion 110-2 (S700).

If necessary, the curing adhesion in step S400 may be performed together with the step S700 as a final step.

Meanwhile, a base material for a core board sold as a general commercial product is generally cut and sold in a predetermined standard size. When a size of either one of the lateral or longitudinal size of the partition panel required is larger than the standard size, It may be necessary to fabricate it as a unit. For example, the standard size of base material for commercially available core board is 1800 * 1200 mm, and the required partition panel size is 1800 * 1600 mm. Such a case does not occur in the case of a toilet door (for example, 1800 * 600 mm) smaller than the standard size of the base material for a core board, but it may occur in the case of a toilet wall partition (for example, 1800 * 1600 mm).

In such a case, two or more square core boards (for example, one 1800 * 1200 mm, one 1800 * 400 mm, and the like) provided so as to achieve the size of the required partition panel in a state where each of the frames are butt- ) Are prepared, and the above-described basic processes are suitably combined to manufacture a partition panel of a desired size. Here, the term 'butt joint' refers to a state in which the opposing edge faces of both core board are butted against each other, and an adhesive may be applied by applying a separate adhesive, but this does not necessarily mean a state in which the adhesive treatment is performed.

11 is a schematic view for explaining a method of manufacturing a partition panel for a building according to another embodiment of the present invention.

First, when at least one of the size of the required partition panel in the horizontal or vertical direction exceeds the size of the core material base material 110R, the number of the square core material boards 110 'and 110 " Step S100 is performed on at least two of the core material base material 110R so that the size of the required partition panel can be achieved in a state where each of the frame parts is butt-jointed with each other.

Next, step S200 is performed on the first core board 110 'among the prepared core boards 110' and 110 '', step S200 is performed on the second core board 110 '', The hot melt adhesive 60 is laminated on each of the first flat portions of the first and second flat surfaces 110 'and 110' '. The working time of the hot-melt adhesive is, for example, about 3 minutes, and the application speed corresponds to about several seconds per side, so that it is possible to proceed the application as described above.

Next, the core boards 110 'and 110' 'are made to be butt-joined to each other so as to form the required size of the partition panel, and the core boards 110' and 110 '' in the mutually butt- Step S300 is performed.

Finally, steps S400, S500, and S600 are performed for the core board 110 ', 110 "in a mutually butt-joined state where the first finishing material 130-1 is attached on the first plane portion , The step S700 is performed.

As described above, the moisture-curing polyurethane hot-melt adhesive acts as one structural layer having its own strength and hardness after being cured. While the finish material is attached to cover the mutual butt joint between the core boards as described above, When the adhesive is applied so as to have a thickness of 80 to 120 mu m, the hardened layer of the hot-melt adhesive 60 and the high-density melamine impregnated paper (HPM) as the finishing materials 130-1 and 130-2 firmly bond the core board on both sides , There is an advantage that the overall mechanical properties of the partition panel are improved despite connecting two or more core boards. These properties can not be obtained with conventional woodworking adhesives.

On the other hand, a finishing material (high-density melamine impregnated paper (HPM)) sold as a general commercial product is generally cut and sold in a standardized predetermined size, and one of the lateral or longitudinal sizes of the partition panel It may be necessary to produce a larger size. For example, the standard size of commercially available high-density melamine impregnated paper (HPM) is 1220 * 2440 mm, and the required partition panel size is 1800 * 1600 mm.

In this case, it is preferable that two or more square-shaped core boards provided so as to achieve the size of the required partition panel in a state in which each of the frame portions are butt-jointed together are prepared, and at the same time, Two or more quadrangular finishing materials provided so as to achieve the size of the partition panel can be prepared, and the basic processes described above can be suitably combined to manufacture the required partition panel.

Particularly, in this case, it is preferable to attach the finishing material so that the position of the mutual butt joints between the core boards and the mutual butt joints between the finishing materials do not coincide with each other (such that the butt joint between the core boards is not exposed) A partition panel can be manufactured.

12 is a schematic view illustrating a method of manufacturing a partition panel for a building according to another embodiment of the present invention.

11, the size of at least one of the lateral or longitudinal size of the required partition panel may be smaller than the size of the first finishing material 130-1 or the second finishing material 130 The size of the partition panel is made to be in a state where the edges of the first and second finishing materials 130'-1 and 130'-1 are in close contact with each other, The first finishing material 130'-1 and the first finishing material 130 '' - 1 are positioned such that the butt joint CP between the first finishing material 130 'and the first finishing material 130' is not exposed.

In addition, a size of the partition panel is formed in such a state that the edges of two or more second finishing members 130-2 are in close contact with each other, and a butt joint CP between the core boards 110 'and 110 " The second finishing material 130-2 is placed in a state where the second finishing material 130-2 is not placed.

When the hot-melt adhesive is applied so as to have a thickness of 80 to 120 탆 while attaching the finish material so that the positions of the mutual butt joints between the core boards and the mutual butt joints of the finish materials do not coincide with each other, And the high-density melamine impregnated paper (HPM) as the finishing materials 130-1 and 130-2 firmly bond the core board on both sides, so that even though two or more finishing materials are successively attached while connecting two or more core boards, There is an advantage that the mechanical properties are improved.

On the other hand, in the case where the size of either one of the lateral or longitudinal size of the partition panel required to be larger than the standard size of the finishing material (high-density melamine impregnated paper (HPM) sold as general commercial products) A partition panel can be manufactured.

That is, two or more square-shaped core boards prepared so as to achieve the required size of the partition panel in a state in which each of the frame parts are butt-joined together, and at the same time, It is also possible to prepare two or more quadrangular finishing materials to achieve the size of the panel and suitably combine the basic processes described above to produce the required partitioning panels so that the orientation of the mutual butt joints between the core boards and the mutual butt By attaching the finishing material so that the joint direction is perpendicular to each other, it is possible to manufacture a partition panel having better characteristics.

13 is a schematic view for explaining a method of manufacturing a partition panel for a building according to another embodiment of the present invention.

The partition panel is manufactured by the method of the embodiment with reference to FIGS. 11 and 12, and in particular, a seam line CP '' between each edge portion of the two or more first finishing materials 130'-1 and 130 ' Is perpendicular to the butt joint CP between the core boards 110 'and 110' '.

In addition, a close seam between the edges of the at least two second finishing members 130-2 is perpendicular to the butt joint CP between the core boards 110 'and 110' '.

When the hot melt adhesive is applied so that the mutual butt joints between the positions of the mutual butt joints of the core board and the mutual butt joints of the core board are perpendicular to each other and the hot melt adhesive is applied to have a thickness of 80 to 120 탆, the cured layer of the hot melt adhesive 60, Since the high-density melamine impregnated paper (HPM) as the finishing materials 130-1 and 130-2 firmly bonds the core board at both sides, but the joints between the core boards and the seam lines of the finishing material do not fundamentally overlap, There is an advantage that the overall mechanical properties of the partition panel are improved even though two or more finish members are successively attached while connecting the core board.

Meanwhile, in the method for manufacturing a partition panel for a building of the present invention, in order to further improve the waterproof property and the flame retardancy of the upper, lower, right and left edges of the partition panel, a separate edge member excellent in waterproof property and flame resistance is adhered on the upper, The partition panel may also be fabricated in the form of a composite panel.

To this end, a rectangular core inner board prepared by cutting a base material for a core board to a required size is prepared, and a separate frame member excellent in waterproof property and flame retardancy is further adhered to the upper, lower, left and right edges thereof, And the first and second finishes can be bonded.

Particularly, in order to prevent the occurrence of a step due to the thickness deviation between the core inner board and the frame member, the thickness of the side portions of the upper, lower, right, and left side edges of the inner core board is measured and a frame member having the same thickness as the measured value is prepared. Can be prevented.

Hereinafter, an embodiment of a method of manufacturing a composite panel-type building partition panel that provides better water resistance and flame retardancy while preventing the occurrence of steps is described.

FIG. 14 is a perspective view showing a partition panel for construction according to another embodiment of the present invention, FIG. 15 is an exploded perspective view showing a partition panel for construction according to another embodiment of the present invention, and FIG. 17 is a perspective view showing a frame member constituting a partition panel for a construction according to another embodiment of the present invention, and Fig. 18 is a perspective view showing another embodiment of the present invention Sectional view illustrating a manufacturing process of a partition panel for a building according to an embodiment of the present invention.

In the following description, the core board coupled with the frame member is referred to as an " inner core board " in order to distinguish it from the " core board " just before bonding the first and second finishers. In this embodiment, the core board is formed through the following steps.

That is, the core material 110A for a core board made of any one of a core board, a particle board, a synthetic resin panel, aluminum, urethane, a resin impregnated reinforcing board, a plywood board and a medium density fiber board is cut to a required size, (110). Then, the thickness of the side portion of the prepared core inner board 110 is measured (S1100).

The base member 120A having a square board shape is cut to a predetermined width on the basis of a plane portion so that the cut width is the same as the thickness of the actual side surface portion of the core inner board 110, The frame member 120 having a flat portion width equal to the thickness of the side portion of the frame member 110 is provided (S1200).

The flat portion of the frame member 120 is correspondingly attached to each side portion of the core inner board 110 (S1300).

As shown in FIGS. 14 and 15, the partition panel 100 of the present embodiment manufactured in the form of a composite panel includes a core inner board 110, a frame member 120, and a finishing material 130 do.

The process of forming a core board in the form of a composite panel will be described below in more detail. Since the description of the adhesion of the finishing material 130 has been described above, the duplicate description thereof will be omitted.

First, the step S1100 of preparing the core inner board 110 will be described.

The core inner board 110 is formed to have a substantially square shape using a material mainly composed of wood so as to have a predetermined thickness. For example, a core board, a particle board, a synthetic resin panel, a resin impregnated board, (MDF) and a medium density fibreboard (MDF). In addition, the core board inner board 110 may be made of a material that can be used.

For example, the base material 110A for a core board shown in FIG. 16A is cut to fit the size of a partition panel 100 for a building to be manufactured, and the core inner board 110A shown in FIG. The thickness t1 of the side surface of the prepared core inner board 110 is measured.

The measured thickness t1 of the side surface of the core inner board 110 is used as a reference value for cutting the edge member 120A to provide the edge member 120. [

Next, the base member 120A is cut to a predetermined width based on the flat surface so that the cut width is equal to the thickness t1 of the actual side surface of the inner board 110, (S1200) of providing a frame member 120 having a flat portion width w2 of the same value as the side portion thickness t1 of the frame member 110 will be described.

The frame member 120 is a beam-shaped member bonded to each side surface of the core inner board 110 to finish the side surface of the core inner board 110. The frame member 120 is made of synthetic resin, resin impregnated reinforcing plate, aluminum, stainless steel , Iron, ceramic, and the like. In addition, the frame member 120 may be made of a material selected from the group consisting of:

Meanwhile, as an example of the frame member 120, a compact panel product, which is commercially available under the trade name of 'Lame', can be used. The 'Lamis' is manufactured by thickening a hard board paper, And is made in the form of hard plastic, and has properties of high strength and elasticity.

For example, the frame member 120A shown in FIG. 17A is cut to fit the size of the frame member 120 to be manufactured, so that the frame member 120 shown in FIG. Can be prepared.

Specifically, as shown in FIGS. 17 and 18A, the base member 120A for a frame member is cut to a predetermined width on the basis of the flat portion, and at this time, the cutting width of the core member inner board 110 The thickness t1 of the side surface portion of the tapered portion is equal to the thickness t1 of the side portion.

The width w2 of the edge member 120 formed by cutting is equal to the thickness t1 of the side surface portion of the core inner board 110 and the thickness t2 of the side surface portion of the edge member 120 is set to be the same Is equal to the thickness t2 of the frame member base material 120A.

At this time, preferably, before cutting the base material base material 120A to a predetermined width, the surface of one or both of the side surface portions of the core inner board 110 and the plane portion of the frame member 120 (A) may be formed in order to increase the adhesive force by the adhesive (G). The processing of the rough surface (A) can be performed by, for example, a sand blast method.

Next, a description will be made of a step S1300 in which the planar portions of the frame member 120 are adhered to the respective side portions of the core inner board 110 in a corresponding manner.

The edge member 120 cut so that the flat portion width w2 is equal to the thickness t1 of the side portion of the core inner board 110 can be determined by the length of each side portion of the core inner board 110 .

14, the frame member 120 to be attached in the longitudinal direction is longer than the longitudinal length of the core inner board 110 by the thickness t2 of the frame member 120 And the frame member 120 attached in the transverse direction is cut to have the same length as that of the core inner board 110.

As described above, after the frame member 120 to be attached in the longitudinal direction and the frame member 120 to be attached in the lateral direction are completed, the side members of the core member inner board 110 are attached to the side surfaces of the frame member 120 And the flat portions are bonded to each other.

At this time, the side surface of the core inner board 110 and the flat surface of the frame member 120 may be made of a silicone or wood bond adhesive. For example, as the above-mentioned adhesive (G), 'Ogong Bond No. 205' manufactured and sold by 'Ohgong Co., Ltd.' can be used.

As described above, since the planar portions of the frame member 120 are made to correspond to the respective side portions of the core inner board 110 and are bonded with the silicone or wood bonding adhesive G, It is possible to prevent moisture from penetrating between the side surface portions of the core inner board 110 and the planar portions of the frame member 120 as well as the planar portions of the frame member 120 being bonded and bonded.

Thereafter, a finishing material 130 is attached on both flat sides of the core inner board 110 to which the frame member 120 is adhered. Explanation of the bonding of the finishing material 130 will be described in detail with reference to the above- Therefore, redundant explanation is omitted.

In order to prevent a step difference from the frame member due to a partial thickness variation that may occur in the core inner board, the thickness of the side walls of the upper, lower, right, and left corners of the core inner board is measured, The step may be prevented from occurring by actually measuring the thickness at a plurality of predetermined positions in a predetermined length over the entire length of each frame and preparing a frame member having the same thickness as the actually measured value.

FIG. 19 is a perspective view showing a core inner board constituting a partition panel for construction according to another embodiment of the present invention. FIG. 20 is a perspective view showing a frame member constituting a partition panel for construction according to another embodiment of the present invention. FIG. 21 is an exploded perspective view illustrating a manufacturing process of a partition panel for a building according to another embodiment of the present invention. Referring to FIG.

In this embodiment, the core board is formed through the following steps.

That is, the base material 1110A for a core board made of any one of a core board, a particle board, a synthetic resin panel, aluminum, urethane, a resin impregnated board, a plywood board and a medium density board is cut into a required size, (1110).

The thicknesses of the side edges of the upper, lower, left, and right edges of the core inner board 1110 are measured, and the thickness is measured for a plurality of predetermined positions P1 to P7 predetermined over the entire length of each edge.

The upper and lower left and right side edge members 1120 of the core inner board 1110 are provided by cutting the base member 1120A having a square board shape to a predetermined length on the basis of the plane portion, The cutting width is cut so as to be equal to the measured thickness of the side portions measured at the positions of the plurality of predetermined positions on the corresponding rim of the inner board 1110 of the core inner board 1110, A frame member 1120 having a flat portion width equal to the side portion thickness over the length is provided.

The square core board 1110 is prepared by adhering the planar parts SC of the frame members 1120 to the respective side faces CC of the core inner board 1110 in a corresponding manner.

Hereinafter, an embodiment of the method for manufacturing a composite partition panel of a composite panel will be described in more detail, taking into account the partial thickness variations that may occur in the core inner board, while providing better waterproof and flame retardancy while preventing the occurrence of steps .

Materials such as core board, particle board, synthetic resin panel, aluminum, urethane, resin impregnated board, plywood and medium density fiberboard which are actually used as base material for core board (1110A) A thickness variation may occur. For example, in the case of a particle board product commercially available in a standard thickness of 30 mm, the measured thickness of each part may have a value of, for example, 26 to 31 mm.

When the thickness of the core inner board 1110 varies in this way, the thickness of the edge members 1120 to be attached to the upper, lower, right, and left sides may be reduced by a surface cutting method, or a method of further attaching the impregnated paper (for example, In the case of using a lamice as a member) is a theoretically possible method, but it causes a considerably disadvantageous aspect in terms of actual manufacturing efficiency.

In this embodiment, a manufacturing method with improved manufacturing efficiency is proposed in consideration of this point.

First, the base material 1110A for a core material board is cut to a required size to prepare a square core material inner board 1110. [

Next, the thicknesses of the side edges of the upper, lower, left, and right edges of the core inner board 1110 are measured, and the thickness is measured for a plurality of predetermined positions P1 to P7 predetermined over the entire length of each edge.

The positions and the number of the points P1 to P7 at the predetermined positions can be appropriately selected according to the degree of deviation of the thickness of the side portions of the upper, lower, right, and left side edges of the core inner board 1110. [ For example, if the deviation between the uppermost side portion thickness TWa and the lowermost side portion thickness TWb is not large, the thickness actual measurement point may be selected to be about 2 to 3, and the deviation must be large or the deviation of the middle portion must be taken into consideration It is preferable to select five or more actual thickness measuring points. In addition, the measurement position may be measured in all of the upper, lower, right and left sides, or only a part thereof may be measured according to the deviation of the thickness of the side portions of the upper, lower, right, and left sides of the core inner board 1110.

It is preferable that the actual thickness of each of the plurality of predetermined positions P1 to P7 for each of the upper, lower, right and left sides of the core inner board 1110 is measured using an ultrasonic thickness gauge. Actual measurement of the thickness may be performed using manual measurement means such as vernier calipers, but it is preferable to use an ultrasonic thickness gauge in consideration of efficiency and accuracy of measurement. For example, MiniTest 403/405/406 manufactured by ElektroPhysik Co., Ltd. may be used as the ultrasonic thickness gauge, and other known products may be applied.

Next, upper and lower left and right side edge members 1120 of the core inner board 1110 are provided by cutting the frame member base material 1120A having a rectangular board shape to a predetermined length on the basis of the plane portion.

At this time, the cutting width of each of the frame members 1120 is cut so as to be equal to the thickness of the side surface portions measured at the positions of the plurality of predetermined positions on the corresponding rim of the core inner board 1110, A frame member 1120 having a flat portion width equal to the side portion thickness is provided over the entire length of each rim of the inner board 1110. [

The cutting of the frame member 1120A having a rectangular board shape is preferably performed using a CNC machine for woodworking, preferably a CNC milling machine for woodworking with a cutting bit. For example, cutting of the frame member 1120A may be performed by using a general sawing saw, but in consideration of efficiency and accuracy of cutting, it is preferable to use a CNC machine for woodworking (CNC milling machine) . As such a woodworking CNC machine (CNC milling machine), for example, CNC-2606 manufactured by Hyundai Woodworking Machinery Industry Co., Ltd. can be used, and other known products can be applied.

Next, the flat portion SC of the frame member 1120 is bonded to each side portion CC of the core inner board 1110 in a corresponding manner.

The flat portion SC of the frame member 1120 corresponds to each side portion CC of the core inner board 1110 before cutting the base member 1120A for the frame member The surface of either or both of the side portions CC of the core inner board 1110 and the flat portion SC of the frame member 1120 is roughened .

Next, a finishing material 1130 is attached on both side flat portions of the core inner board 1110 to which the frame member 1120 is bonded.

Preferably, the core inner board 1110 is made of any one of a core board, a particle board, a synthetic resin panel, aluminum, urethane, a resin impregnated reinforcing board, a plywood board and a medium density fiberboard board. ) Is made of any one of synthetic resin, resin impregnated reinforcing plate, aluminum, stainless steel, steel, ceramic, and the finishing material 1130 is composed of an impregnated paper containing incombustible or semi-incombustible flame retardant melamine resin.

22 is an exploded perspective view illustrating a manufacturing process of a partition panel for a building according to another embodiment of the present invention.

In the case of FIGS. 19 to 21, the core inner board 1110 has a predetermined thickness deviation slope. However, as shown in FIG. 22, when a thickness deviation is irregular for each part rather than a constant deviation slope, There is an advantage that it is possible to manufacture a step-free product.

In Figs. 19 to 21 and Fig. 22, the thickness variation of the illustrated inner core board is exaggerated for convenience of explanation.

In the case of manufacturing a partition panel for a building in the same manner as the present embodiment, even when a base member (for example, 18 mm) having a relatively small standard thickness as compared with the standard thickness (for example, 30 mm) And has good advantages in terms of efficiency. For example, considering a case where a lamice board having a thickness of 18 mm and a laminate board having a thickness of 30 mm are attached as a frame member to a core material having a thickness of 30 mm, conventionally, in a state in which two laminated boards of 18 mm in thickness are laminated (36 mm) 6 mm), or the additional impregnated paper must be attached until the 18 mm thick lamis board is 30 mm thick. This method suffers from a problem of poor thickness accuracy and inferior working efficiency there was. However, when a partition panel for a building is manufactured in the same manner as the present embodiment, it has a considerably good advantage in terms of work efficiency.

Although the present invention has been described with reference to the preferred embodiments thereof with reference to the accompanying drawings, it will be apparent to those skilled in the art that many other obvious modifications can be made therein without departing from the scope of the invention. Accordingly, the scope of the present invention should be interpreted by the appended claims to cover many such variations.
