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

1 is a perspective view for explaining a base material for a frame member constituting a waterproof panel according to an embodiment of the present invention. 2 is a perspective view illustrating a core board constituting a waterproof panel according to an embodiment of the present invention. 3 is a perspective view for explaining a process of manufacturing a frame member constituting a waterproof panel according to an embodiment of the present invention.

In step S1, the double-sided adhesive sheet 121 is attached to one flat surface portion of the frame member base material 120A having a square board shape. The double-sided adhesive sheet 121 can be used in waterproof panels of this embodiment as long as it is a known product used for bonding wood or the like and is waterproof, and is not limited to any one kind.

In step S2, widths of the side CCs are measured with respect to the plurality of points P1 to P8 over the entire length of each of the upper, lower, right, and left sides of the core board 110.

As the core board of this embodiment, a core board, a particle board, a synthetic resin panel, an aluminum board, a urethane, a resin impregnated reinforcing board, a plywood, a medium density fiber board, a magnesium board, an aluminum honeycomb, a PVC foaming panel, a PS (polystyrene) Styrene, gypsum board, stainless steel, foam aluminum and the like are used.

Materials such as core board, particle board, synthetic resin panel, aluminum, urethane, resin impregnated board, plywood, and medium density fiber board which are actually used as core board 110A are different in thickness ) Deviation 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 position may have a value of, for example, 26 to 31 mm.

In the case where the widths of the side portions of the core board 110 vary in this way, the thickness of the edge members 120 to be attached to the upper, lower, right, and left sides may be reduced by a surface cutting method, 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.

Considering this point, a more efficient manufacturing method is proposed.

First, the widths of the side CCs of the upper, lower, left and right edges of the core board 110 are measured, and the thickness is measured for a plurality of predetermined positions P1 to P8 predetermined over the entire length of each frame .

The positions and the number of the points P1 to P8 at the predetermined positions can be appropriately selected according to the degree of deviation of the side CCs of the upper, lower, left, and right edges of the core board 110. [ For example, if the deviation between the width TWa of the uppermost side portion CC and the width TWb of the lowermost side portion CC is not large, the thickness actual measurement point may be selected to be about 2 to 3, It is desirable to select five or more actual thickness measuring points in the case where the deviation of the intermediate portion is to be considered. In addition, the measurement position may be measured in all of the upper, lower, right and left sides, or only a part of the measurement positions may be measured according to the degree of deviation of the side CCs of the upper, lower, right and left sides of the core board 110.

The actual measurement of the width of the side CC with respect to the plurality of predetermined positions P1 to P8 for each of the upper, lower, left and right sides of the core board 110 may be performed using manual measurement means such as a vernier caliper However, in consideration of the efficiency and accuracy of measurement, an ultrasonic thickness gauge may be used.

2, the deviation of the widths of the side portions CC at each of the points P1 to P8 is somewhat exaggerated, and the actual deviation is 0.05 to 1 depending on the thickness and material of the core board 110 mm, or there may be a deviation of about 2 to 3 mm.

In step S3, the upper and lower left and right side edge members 120 of the core board 110 are prepared by cutting the base member 120A having a rectangular board shape to a predetermined length with reference to the flat surface portion 120A '.

The frame member 120 is a beam-shaped member bonded to each side surface of the core board 110 to finish the side surface of the core board 110. The frame member 120 of this embodiment is preferably made of a waterproof material such as a synthetic resin, a resin-impregnated reinforcing plate, aluminum, stainless steel, steel, and ceramics. As an example of a waterproof synthetic resin-based material, a compact panel product that is commercially available under the trade name of 'LAMIS' can be used. The 'LAMIS' mentioned above is produced by thickening a hard board paper, impregnating the resin into a resin, It is made in the form of plastic and has high strength, elasticity and waterproofness.

At this time, the cutting width of each of the frame members 120 is cut so as to be a value corresponding to the width of the side CC measured in relation to the corresponding edge of the core board 110, A frame member 120 having a flat portion SC width corresponding to the width of the side portion CC is provided over the entire length of the frame. Here, the 'corresponding value' may be understood to be the same value, and a value to the extent that there is an auger to the extent that it is difficult to see a substantial difference may be understood as a corresponding value. For example, when the measured width CC of the side portion is 30 mm, the tolerance range of about 29.5 to 30.5 mm (± 0.5 mm) can be understood as a corresponding value.

Cutting of the frame member 120A having a rectangular board shape may be performed by using a general sawing saw, for example, but considering the efficiency and accuracy of cutting, the CNC machine for woodworking (CNC milling machine) . ≪ / RTI >

4A and 4B are partial schematic views for explaining the surface treatment of the edge member of the waterproof panel according to the embodiment of the present invention.

In step S4, the waterproofing grooves 122a and 122b are formed on the left side surface 120 '' and the right side surface 120 'of the planar portion SC of the rim member 120. Preferably, the waterproofing grooves 122a and 122b are formed at a depth of 0.04 to 0.06 mm in consideration of the smoothness of inflow of the hot-melt adhesive agent and the effect of preventing moisture penetration. The width of the groove can be suitably formed in the range of 0.04 to 0.1 mm.

The waterproofing grooves 122a and 122b may be formed using a known sanding roll or a sawtooth bit (or circular top bit).

The waterproofing grooves 122a and 122b may include a first waterproofing groove 122a formed in an oblique direction with respect to the longitudinal direction of the frame member 120 and a second waterproofing groove 122a extending in the length direction of the frame member 120 And a second waterproofing reinforcing groove 122b formed in another oblique direction with respect to the direction of the second waterproofing reinforcement. The intersection angle a between the first waterproofing grooves 122a and the second waterproofing grooves 122b may be in the range of 30 to 60 degrees.

When the hot melt adhesive 60 is applied and the finishing material 130 is adhered as described later in a state in which the waterproofing grooves 122a and 122b in the diagonal direction are formed at a depth of 0.04 to 0.06 mm, Moisture penetrating between the frame member 120 and the sheet of the finishing material 130 is further blocked by the waterproofing grooves 122a and 122b and the hot melt adhesive cured therein, It is confirmed that the possibility of penetration of moisture to the joint portion with the water is greatly reduced.

Particularly, when the waterproof reinforcement grooves 122a and 122b in the diagonal direction are formed in two or more directions, a plurality of waterproofing grooves 122a and 122b formed in the direction intersecting each other can prevent moisture from penetrating into the core board from the edge member. It is confirmed that the moisture penetration effect is better than that in the case where only one directional groove is formed.

More preferably, the first waterproofing strengthening groove 122a and the second waterproofing strengthening groove 122b are formed so as not to reach the bonding position of the core board 110 and the frame member 120 .

4B, the first waterproofing strengthening groove 122a and the second waterproofing strengthening groove 122b are formed at the bonding position 121 between the core board 110 and the frame member 120, To a position having a predetermined gap (M).

When the first waterproofing strengthening groove 122a and the second waterproofing strengthening groove 122b are formed in this structure, a plurality of waterproofing grooves 122a and 122b crossed in two directions are formed on the edge member And the adhesive portion 121 of the core board 110 and the frame member 120 is isolated from the waterproofing grooves 122a and 122b so that the waterproof reinforcement grooves 122a and 122b are separated from each other, It is possible to obtain an effect of further blocking the penetration of some moisture, which may penetrate into the inside, toward the core board side.

Meanwhile, the first waterproofing grooves 122a and the second waterproofing grooves 122b may be formed at different depths. For example, the first waterproofing reinforcing groove 122a may be formed to have a depth of 0.04 mm, and the second waterproofing reinforcing groove 122b may have a depth of 0.06 mm. When the first waterproofing reinforcing groove 122a and the second waterproofing reinforcing groove 122b are formed at different depths, the hot melt adhesive introduced into the first waterproofing reinforcing groove 122a and the second waterproofing reinforcing groove (For example, cooling rate) is generated in the curing environment during curing of the hot-melt adhesive introduced into the hot-melt adhesive 122b, so that there is a slight difference in the adhesive properties after curing. Therefore, Even when deterioration occurs in the adhesive layer in the groove in one direction, it is possible to prevent deterioration at the same time in the adhesive layer in the groove in the other direction.

In step S5, the planar parts SC of the frame member 120 are made to correspond to the respective side parts CC of the core board 110 through the double-side adhesive sheet 121.

6, the width w2 of the planar portion SC of the edge member 120 corresponds to the width t1 of each side CC of the core board 110. As shown in FIG.

By adhering the adhesive portions in exactly the same width, it is possible to prevent the occurrence of stepped portions that are vulnerable to moisture penetration, so that a better waterproof effect can be obtained.

Reference numerals 120a to 120d that are not shown represent edge members in the vertical and horizontal directions.

7 is a schematic view illustrating a process of applying a hot-melt adhesive in a heated molten state according to an embodiment of the present invention.

In step S6, hot melt adhesive 60 is applied to both sides of the core board 110 and the edge member 120 bonded thereto, and the finish material 130 is attached.

The step S6 may be performed in more detail as follows.

In step S61, the hot melt adhesive 60a is applied to the first surface 110a of the core board 110 and the first finish material 130a is attached.

In step S62, the hot melt adhesive 60b is applied to the second surface 110b of the core board 110 and the second finish material 130b is attached. After the operation of the first surface 110a, the operation of the second surface 110b may be performed while the core board 110 is turned upside down.

In step S63, a hardening condition is applied to the hot-melt adhesive 60, 60a, 60b to harden and bond the first finish material 130a and the second finish material 130b. The curing conditions may be provided by the desired curing environment (curable temperature and time) over which the curing of the adhesive may be effected.

Preferably, the first and second finishing materials 130a and 130b are made of a waterproof synthetic resin, an aluminum sheet, or the like. For example, the first finishing material 130a and the second finishing material 130b are formed of HPL (High Pressure Laminate) sheet.

HPL (High Pressure Laminate) is a material called HPM (High Pressure Melamine), which is impregnated with thermosetting resin on paper and fibrous base materials. It is designed in color and pattern on one side or both sides and has a suitable heat and pressure of 35-50kgf / And the like. HPL (High Pressure Laminate) is a flame retardant and waterproof material with a heat resistance of 135 ° C or higher, and can express various colors and designs including shapes that determine color and design.

Preferably, the hot-melt adhesive 60 is a moisture-curing polyurethane hot-melt adhesive. In addition, the hot-melt adhesive 60 is applied with a thickness of 0.8 to 1.2 mm based on the coated surface of the core board 110.

As the hot-melt adhesive 60, a moisture-curing polyurethane hot-melt adhesive is used. 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 so as to have a thickness of preferably 0.8 to 1.2 mm and serves as one waterproof layer having a thickness The waterproof property of the entire waterproof panel is improved.

For example, the hot-melt adhesive 60 may be applied by the following process and the finish adhering process may be performed.

The hot melt adhesive 60 is heated and melted through the application roll 50 rotating on the first flat surface portion 110a of the core board 110 while the core board 110 with the edge member 120 is carried, And then laminated.

The inventors of the present invention have confirmed that it is preferable to form a coating thickness of 0.8 to 1.2 mm in order to secure an adhesive force and a waterproof property when a hot melt adhesive is applied for the purpose of adhering a covering sheet for forming a waterproof panel for construction . Advantages in terms of waterproofing property when using the hot-melt adhesive will be described later with reference to Fig.

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 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).

As described above, since the waterproof panel of this embodiment is used in an environment such as a bathroom with a lot of moisture and moisture, if a moisture-curable polyurethane hot-melt adhesive is used as an adhesive, There is an advantage that it can be obtained.

In the present embodiment, the hot-melt adhesive 60 is preferably applied using a roll coater. 7, molten hot-melt adhesive 60 is supplied to a roll coater through a supply unit (not shown) and is 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.

Considering the size of the conventional core board 110, the working time of the hot-melt adhesive takes, for example, approximately several seconds per application surface.

The attachment of the finishing material may be accomplished by, for example, attaching a first finishing material 130a of appropriate size onto the first plane portion 110a of the core board 110 to which the hot melt adhesive 60 has been applied, , And the core board with the finishing material attached thereto is passed through a general roll press apparatus. The transfer from the roll coater to the roll press can be accomplished by conventional rail-type transfer equipment.

8 is a perspective view illustrating a waterproof panel according to an embodiment of the present invention. 9 is a partial cross-sectional view illustrating a state where a bolt is coupled to a waterproof panel according to an embodiment of the present invention.

In the present embodiment, the hot-melt adhesive 60 serves as one waterproof layer having a thickness after the cured layer is formed to have a thickness of 0.8 to 1.2 mm.

Generally, as shown in FIG. 9, bolts 502 and 504 penetrating the panel are installed in the composite panel for a toilet, in order to install a door hinge 500, a hanger, various metal fittings, and the like.

When the hot melt adhesive layer 60 is formed to have a predetermined thickness as in the present embodiment, the hot melt adhesive 60 adheres to the surface of the threaded portion 504a when the bolt 504 is rotated, So that the moisture penetration through the gap of the bolt 504 fastening hole can be blocked more effectively. When the hot-melt adhesive 60 is applied in a thickness of 0.8 to 1.2 mm, the waterproof effect by such an adhesive layer 60s is favorably provided.

Reference numeral 508 denotes a reinforcing member for installing the door hinge 500.

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.
