Description

Finishing board

The present invention relates to a plate for finishing, and more particularly, to a plate for finishing to enable the use of natural stone plate, such as marble or granite, or ceramic plate of ceramic or magnetic system for finishing on the floor and wall.

Today, natural stone materials such as marble and granite are used in a variety of construction materials. In particular, natural stone is often used as a finishing material for finishing the visible part, that is, the exterior wall, inner wall and floor of the building, in order to decorate the building luxuriously because of the advantage of being a natural material that can provide non-uniform natural beauty. .

Such natural stone is generally constructed in the form of a plate, which is weak in compressive strength, impact strength, and tensile strength, and in the case of a plate, in particular, it is very weak to impact due to brittleness in the material, which is a risk of damage in construction or in use. In consideration of the risk of breakage, but may vary depending on the type, it is generally used in a thickness of at least 10mm to 30mm.

However, although the thickness of about 10 mm to 30 mm can be said to be thin, the density of the natural stone is very high, and thus has a considerable weight. Such a considerable weight may put a structural burden on the building, and therefore, when a finish using natural stone is scheduled, it is necessary to consider the load separately from the design stage and to increase the cost of foundation work.

In addition, the handling for construction or transportation must be careful, and as construction is difficult, requiring careful attention to orderly alignment of the vertical and horizontal in the construction process, the construction cost burden is also considerable.

Due to such a cost burden, natural stone material is not generally used in the construction of a general house, and is mainly applied to high-end constructions with a construction cost.

On the other hand, the present applicant has developed a finishing plate as disclosed in Patent Publication No. 10-2009-0121166 in view of this point.

Such a conventional finishing plate will be described with reference to FIGS. 1 and 2.

As shown in FIG. 1, the finishing plate is cut to a natural stone surface plate 10 of a predetermined thickness cut to a predetermined length and width, and cut to a length and width corresponding to the natural stone surface plate. Reinforcement plate 20 is attached to the lower surface of the), and the base plate 30 is cut to have a length and width larger by a predetermined dimension than the natural stone surface plate 10 is attached to the lower surface of the reinforcing plate 20.

The natural stone surface plate 10, the reinforcing plate 20 and the base plate 30 is integrated in a manner of bonding using a contact portion to the contact portion. Specifically, a hot melt adhesive, particularly a moisture-curable urethane hot melt adhesive, is applied by using a hot melt applicator to about 100 to 150 g, or about 100 to 150 g by using a cold pressure adhesive including vinyl acetate and an isocyanate curing agent. Then, using a roll press machine or a hydraulic cold press, the compression process is performed for 30 to 60 minutes at a pressure of about 3 to 5 kg / ㎠ and left at room temperature for 48 hours to completely cure the adhesive. Will go through.

The natural stone surface plate 10 is made of a natural stone plate, such as marble or granite, is processed to have a thickness of about 3 to 5 mm, length and width may be determined in various dimensions. In addition, the corner of the upper surface is preferably chamfered in order to prevent the occurrence of breakage during handling for transportation or construction.

The reinforcement plate 20 is provided to reinforce the impact strength, the compressive strength, and the tensile strength of the natural stone surface plate 10. An aluminum composite having two aluminum plates attached up and down with a plastic plate such as PE interposed therebetween. It is composed of any one plate selected from a single plate, such as a plate or a glass fiber plate, fiber reinforced cement board (CRC board), magnesium board, urethane foam plate, but in Figure 1 illustrates a single plate. In particular, in the case of an aluminum composite sheet, it is preferable that the plastic sheet and the aluminum sheet are also integrated through a method of adhering to the contact portion using an adhesive. On the other hand, by having such a reinforcing plate 20, the impact strength, compressive strength and tensile strength of the natural stone surface plate 10 is significantly improved, and the floor and wall finishing plate using the finished natural stone is sufficient durability Will have

In addition, the base plate 30 may be formed of a sheet of wood, such as plywood, a high density fiber board, a cut sheet and a synthetic wood, or an injection molded thermoplastic ABS resin or a compression molded thermosetting melamine resin material. The base plate 30 has side receiving portions 31 and end receiving portions 33 having independent shapes on one side of the longitudinal direction and one end of the width direction, respectively, and side protrusions 32 correspondingly coupled to the opposite sides. ) And the end protrusion 34 are formed to protrude. Particularly, the side accommodating part 31 and the end accommodating part 33 are formed as grooves having a shape surrounded by an upper wall, a side wall, and a lower wall, but the upper wall and the lower wall are upper wall removal sections 37 having a predetermined unit dimension from which the upper wall and the lower wall are removed, respectively. ) And the lower wall removal section 38 is formed in a continuous shape alternately. In addition, the base plate 30, except for a predetermined portion of the edge honeysuckle consisting of a plurality of rectangular cross-sectional groove (not shown) or hexagonal cross-sectional groove 35 (hereinafter referred to collectively as "hexagonal cross-sectional groove") that is open to the upper surface side. The comb structure is formed. This is to ensure that the finishing plate of the structure in which the heterogeneous materials are integrated in a flat balance to make the construction work more convenient.

And, the hexagonal cross-sectional groove 35 is formed with a vent hole 36 penetrating the center portion, the vent hole 36 can be arranged in accordance with a predetermined arrangement rule, all hexagonal cross-sectional groove 35 Although each may be provided one at a time, it is preferable that the number is provided in an appropriate number to have an arrangement with a certain interval. Such a vent 36 is to promote the complete curing of the moisture-curable urethane hot melt adhesive used for bonding between the base plate 30 and the reinforcing plate 20, the water vapor in the air through the vent 36 It can be provided to the moisture-curable urethane hot melt adhesive between the base plate 30 and the reinforcing plate 20 to improve the adhesion through the complete curing of the moisture-curable urethane hot melt adhesive.

However, the conventional base plate 30 can integrate heterogeneous materials by a honeycomb structure composed of hexagonal cross-sectional grooves 35 whose top surface is opened, but the honeycomb structure is formed only on the top surface. Since the upper and lower surfaces of the 30 form an asymmetrical structure, the upper surface of the base plate 30 is weaker than the lower surface of the structure 30, so that both ends of the manufactured base plate 30 are cured upward and deformed.

In addition, when the conventional base plate 30 is formed of a thermoplastic ABS resin, the base plate 30 of the thermoplastic material is the heat of the pipe for indoor heating directly acts on the base plate due to the installation characteristics of the finishing plate material There was a problem that the base plate 30 can be easily softened and deformed. In addition, when the conventional base plate 30 is formed of a thermosetting melamine resin, the resin constituting the melamine resin has a large burden on the cost and can not be reused, which may cause environmental problems.

Therefore, the present invention has been made to solve the problems of the prior art as described above, the base plate to enable the use of natural stone plate or ceramic plate such as marble or granite for finishing on the floor and walls in a vertically symmetrical structure By forming the weight of the base plate and the finishing plate light weight, the stable balance by the vertically symmetrical structure prevents deformation of the base plate, and provides a finishing plate that can improve the strength and bonding strength of the base plate. There is a purpose.

The above object is a finishing plate material comprising a natural stone surface plate formed in a predetermined size and thickness, a reinforcing plate formed to correspond to the natural stone surface plate and fixed to the natural stone surface plate, and a base plate attached and fixed to the reinforcement plate In the above, the base plate is achieved by the finishing plate, characterized in that the honeycomb structure is formed in a vertically symmetrical structure in which the cross-sectional grooves open to the upper surface side and the cross-sectional grooves opened to the lower surface side alternately and continuously formed.

In addition, the above object is a finishing plate comprising a ceramic plate formed of a predetermined size and thickness, and a base plate attached to and fixed to the ceramic plate, wherein the base plate is opened to the lower surface side and the cross-sectional groove opening to the upper surface side A honeycomb structure in which cross-sectional grooves are formed repeatedly alternately is also achieved by a finishing plate material characterized by being formed in a vertically symmetrical structure.

In addition, each of the ventilation holes are formed in the cross-sectional grooves of the base plate, and through the upper surface of the cross-sectional grooves open to the lower surface side of the base plate, holes of small diameters are perforated, The lower surface is preferably a perforated aperture of large diameter, the base plate is preferably formed of a BMC or SMC material containing glass fibers of the thermosetting resin.
