The present invention relates to a panel for building construction using natural stone, and more particularly to an assembly member that can be assembled with a building structure (wall, frame, ceiling, floor, etc.) The present invention relates to a panel for building construction using natural stone, which has a smooth surface while showing the texture of natural stone as it is by providing an assembling member capable of being built flat on the building structure.

Recently, in order to enhance the quality of buildings, attempts have been made to express natural texture. The most common method for this is a method of cutting and cutting natural stone such as marble into a plate and then attaching it to the wall of the building by a wet method using mortar. However, although the natural texture of marble can be expressed as it is, marble is difficult to handle in the process of processing, transporting and adhering marble due to fragility, so that it is difficult to manufacture with a large size, The air and the labor are increased.

In addition, there has been attempted a method of expressing a natural texture by mixing natural stone crushed with sand into an adhesive and then finishing and finishing it on the wall of the building. However, since this method is also applied with a wet method, Is increased. In this method, inevitably, natural stone should be crushed to a sand size in order to be finished. In this case, the grain size of the natural stone is too small so that the texture of the natural stone can not be expressed exactly and the quality of the product is determined according to the skill of the handicraft. There is a problem in that it does not have a smooth surface.

On the other hand, a prefabricated panel that is easy to construct is used for finishing the surfaces of the inner and outer walls, the ceiling, and the floor of the building. Generally, the prefabricated panels are made of a multi-layered structure. Specifically, it has a structure in which a surface layer of a metal material or a plastic material and a heat insulating material layer or a sound absorbing material layer inside are stacked. A plurality of such prefabricated panels are assembled to a steel frame frame to form a wall of the building or a concrete wall of a building, a ceiling, a floor or the like to form a surface. At this time, Fixtures such as bolts, brackets, etc. are used in connection with the building structure (steel frame, concrete wall of the building, ceiling, floor, etc.).

Particularly, a sandwich-type three-layered prefabricated panel in which a heat insulating material is filled in a prefabricated panel for the purpose of heat insulation and a thin metal plate is attached as a surface layer on both sides thereof is widely used. At this time, styrofoam is mainly used as a heat insulating material to be filled in the inside.

Figures 1 and 2 show a prefabricated panel according to the prior art. The front panel metal sheet 15 and the rear panel metal sheet 20 which are attached to both surfaces of the heat insulating layer 10 and constitute a surface layer, ), Which has a three-layer structure. The protrusions 25 and the grooves 30 are provided at both ends of the protrusions 25 and the grooves 30 so that the protrusions 25 and the grooves 30 can be fitted and assembled with each other. As shown in Fig. 2, the projecting portion 25 is provided with a plurality of projections (not shown) which are vertically and horizontally arranged so as to be coupled to a steel frame 4 of a building vertically or horizontally arranged on the ground by bolts, brackets, Fastener fastening holes 27 are formed. At this time, since it is difficult to cut the heat insulating material layer 10 into the shape corresponding to the protruding portion 25 and the groove portion 30, the both side ends and the upper and lower ends thereof are cut into straight lines so as to be generally rectangular. A predetermined space portion 33 is formed between both side ends of the heat insulating material layer 10 and the groove portion 30 and the projection portion 25. The space portion 33 is filled with urethane 36 . In order to inject or attach the urethane 36 to the ends of the front metal plate 15 and the rear metal plate 20 or to attach the front metal plate 15 and the rear metal plate 20 to the styrofoam A spacing portion 17 having a predetermined spacing is necessarily formed.

Therefore, it is possible to easily construct the surface of the building by fixing the prefabricated panel to the steel frame 4 or the like through the fixture fastening holes 27 of the protrusions 25 and continuously connecting the other prefabricated panels in left and right and up and down directions.

The above-described prefabricated panel has excellent heat insulation, is easily combined with a simple assembly method, is easy to construct, and is widely used not only for large buildings such as factories, warehouses, gymnasiums or public facilities, but also for buildings, general houses and the like because of surface smoothness.

However, the above-described prefabricated panel according to the related art has a problem that the styrofoam used as the heat insulating material layer 10 inside the panel is burned, melted and corroded in the case of a fire to easily damage the panel. That is, as shown in FIGS. 1 and 2, the metal steel plates 15 and 20 are not attached to the side surface (the plane in the drawing) that is a portion corresponding to the narrow surface, So that there is a problem that the heat insulating material layer 10 is fired and the fire is intensified. In addition, when the heat insulating material layer 10 is exposed as described above, it is corroded by the oxidizing action by the external oxygen, and at the same time, there is a problem that the heat insulating material is shrunk to deteriorate the heat insulating property.

As described above, in the related art, the fixtures 3 such as bolts, brackets, and the like are used to connect the prefabricated panel and the building structure (steel frame, concrete wall, ceiling, floor, etc.) A steel frame, a concrete wall of a building, a ceiling, a floor, or the like) has a non-flat surface, the panel can not be assembled flat. This will be described with reference to FIG.

As shown in Fig. 3, there is a case where a building structure (a steel frame, a concrete wall of a building, a ceiling, a floor or the like) such as a concrete wall 2 of a building is not flat or a portion 2a protruding from the wall 2 There is a problem in that the panels 1 can not be flatly assembled to each other but become convex.

Conventionally, in the construction of a wall of a building, a column is formed by a steel frame such as an H beam or an I beam. Then, bricks are laid between the steel frame or concrete is laid thereon. The method of constructing the wall was common. However, in this case, there has been a problem that the cost of the material itself is high and the heat insulation is poor, in addition to the increase of the air and labor due to the masonry of the brick and the concrete pouring.

The present invention has been made in order to solve the problems of the prior art as described above, and it is an object of the present invention to provide a construction panel for building having a multi-layer structure, in which a surface layer is made of a natural stone granular layer, The object of the present invention is to provide a prefabricated panel.

The glass-

The glass fiber mortar layer 120 is formed by placing glass fiber mortar on the entire surface of the heat insulating material layer 110 so that the heat insulating material layer 110 is not exposed to the outside. Accordingly, the prefabricated panel 100 of the present invention has a structure in which the heat insulating material layer 110 is inserted into the glass fiber mortar layer 120, and the heat insulating material layer 110 is not exposed to the outside.

At this time, the glass fiber mortar constituting the glass fiber mortar layer 120 is made of glass fiber, sand, cement, and water to prevent the heat insulating material layer 110 from being exposed to the outside, 110 and prevents the panel 100 from being exposed to light and gives excellent strength and flexural rigidity. Fine sand is used as the sand, preferably silica sand is used. When the glass fiber mortar is coated on the heat insulating material layer 110, it is important that the glass fibers are uniformly dispersed in the entire region of the glass fiber mortar layer 120 without aggregation.

That is, the extension part 125 integrally connects the upper and lower glass fiber mortar layers 120 and the central heat insulating material layer 110 to strengthen the strength of the panel 100, .

The natural stone granular layer 130 is formed on at least one surface of the glass fiber mortar layer 120. The natural stone granular layer 130 may be formed on one side or both sides of the glass fiber mortar layer 120, and FIG. 4 illustrates the shape formed on both the upper and lower sides. 10 shows a state in which the natural stone particle layer 130 is formed on only one upper surface of the glass fiber mortar layer 120. As shown in FIG. The natural stone granular layer 130 is formed by applying a mixture of natural stone particles 132 and a binder 134 onto the glass fiber mortar layer 120 and hardening the outer surface of the natural stone granular layer 130, will be. That is, as shown in FIG. 4, the surface is etched using a polishing machine so that the natural stone particles 132 are uniformly densely fixed by the binder 134 and have a smooth surface.

The natural stone particles 132 may be selected from various kinds of natural stone such as marble, granite and the like, and it is preferable that the natural stone be used in a size of more than a millet as much as possible, more specifically, a size of 3 mm or more. More specifically, although not particularly limited, it is preferable to use a size in the range of 3 mm to 15 mm. At this time, if the size of the natural stone particles 132 is smaller than 3 mm, the natural texture is lowered. If it is larger than 15 mm, the adhesion by the binder 134 is lowered, and a polishing operation for obtaining a smooth surface may be required. The binder 134 may be a resin having adhesiveness so as to fix the natural stone particles 132. For example, an acrylic resin, a urethane resin, a propylene resin, or the like may be used.

In addition, when using the natural stone particles 132, only one kind of natural stone particles 132 having the same color may be used, or various kinds of natural stone particles 132 having various colors may be mixed and used. At this time, when various kinds of natural stone particles 132 are mixed and used, different colors may be used and various patterns may be expressed in the natural stone particle layer 130. That is, two or more kinds of natural stone grains 132 having different colors are used. For example, a shape of a character, a circle, a triangle, a quadrangle, a pentagon, an octagon, and the like, as well as a flower, an animal, a figure, a cross, a bird, a tree, a rainbow, a waterfall, a mountain, a car, an airplane, a train, a building, and a plant. More specifically, as shown in Fig. 6, black stone natural stone particles 132 are used for the character " Youngsan ", and the background portion excluding the character " Can be used to prominently express the pattern of the character "Youngsan".

The assembled panel 100 of the present invention may be assembled or joined to a building structure (a concrete wall, a steel frame, a ceiling, a floor, or the like) in a state of being in close contact with an adjacent panel 100, So that they can be assembled to each other and assembled to each other. Such an assembling structure may be a concave-convex structure or a fitting groove 151 and a fitting protrusion 152 as shown in FIG. 7) or formed only on the upper and lower sides (as viewed in FIG. 7, i.e., the plane and the bottom face), and the fitting protrusions 151 and the fitting protrusions 152 are formed only on the left and right sides And formed on both the upper and lower surfaces as well as the left and right side surfaces. In Fig. 7, the left and right side surfaces are illustrated.

7, the thickness h1 and the thickness h2 of the fitting groove 151 and the fitting protrusion 152 are set to be equal to each other, 1), 2/5, 1/3, or 2/3. 8, the thicknesses h1 and h2 of the fitting groove 151 and the fitting protrusions 152 are different from each other, and the thickness h1 of the fitting groove 151 is set to be larger than the thickness h1 of the panel And the thickness h2 of the fitting protrusion 152 is set to 1/3 of the thickness H of the panel 100 so that the empty space 155, 100) and the empty space 155 corresponding to 1/3 of the thickness H can be formed. The hollow space 155 is used as a space for inserting pipes for electricity, gas, cold / hot water, etc., or as a space into which a steel frame frame or the like as a building structure can be inserted, And can be used as a means to do so.

A mold (mold) is used for manufacturing the panel 100, and the mold may be composed of a lower mold and an upper mold. At this time, the lower mold is shaped as a side assembly structure so as to form a fitting groove 151 and a fitting protrusion 152.

First, a plurality of inlet holes 115 are formed in a heat insulating material (styrofoam, glass wool, urethane foam, or the like). Then, sand, cement, and water are mixed with a large drum to prepare a slurry-like mortar. Then, the insulator having the inlet hole 115 is impregnated with the slurry, then taken out and slightly cured. The reason why the heat insulating material is impregnated into the mortar is to improve the bonding force between the heat insulating material layer 110 and the glass fiber mortar layer 120 to be coated thereon.

Next, mortar mixed with sand, cement and water is separately sprayed (sprayed) onto the lower mold, and the glass fibers are evenly sprayed thereon. Here, the reason why the mortar and the glass fiber are injected separately without mixing them together is to prevent the glass fiber from being bundled. After inserting the glass fiber mortar layer 120 having a predetermined thickness in the lower mold, the heat insulating material impregnated with the mortar is laminated thereon. Then, the mortar is sprayed (sprayed) onto the heat insulating material as described above, and the glass fiber is sprayed evenly and separately so that the glass fiber mortar layer 120 is coated on the outside of the heat insulating material to a predetermined thickness. Next, the upper mold is pressurized to compose the tissue, and at the same time, the semi-finished product having the glass fiber mortar layer 120 coated on the surface of the heat insulating material layer 110 is completed when cured. Then, a mixture of the natural stone particles 132 and the binder 134 is coated on one or both surfaces of the glass fiber mortar layer 120, and then the mixture is polished. Then, the outer surface is polished to form a natural stone granular layer having a smooth and smooth surface 130) can be obtained.

Particularly, it is preferable that the kind and color of the natural stone particles 132 'are the same as those used for the natural stone particle layer 130 constituting the panel 100 itself.

Hereinafter, a method of constructing a wall of a building according to the present invention will be described with reference to FIGS.

Referring to FIG. 11, first, a steel frame 220 that forms a skeleton of a building is assembled and constructed. At this time, an H beam, an I beam or the like is used as the steel frame 220, and the steel frame 220 is coupled vertically and horizontally so as to have one or more layers and a plurality of rooms in one layer .

11, a plurality of subframes 230 are assembled between the steel frame 220 to form a plurality of empty spaces S, as shown in FIG. At this time, the steel frame 220 and the sub frame 230 and the sub frame 230 and the sub frame 230 are welded or bracketed. The subframe 230 may be made of a steel product such as a pipe or C-shaped steel.

After the plurality of empty spaces S are formed using the subframe 230 as described above, the heat insulating material 110-1 is inserted into the empty space S. At this time, the heat insulating material 110-1 is a plate-like styrofoam, a glass wool, a urethane foam or the like, and the same thickness as that of the subframe 230 is used. Of course, it is preferable that the size of the heat insulating material 110-1 is equal to or slightly larger than the size of the empty space S so that the empty space S can be filled up tightly.

After inserting the heat insulating material 110-1 into the empty space S as described above, the finishing operation is performed. Specifically, as shown in FIG. 12, a finishing operation is performed to form a finishing layer 250 on inner and outer surfaces of the wall. At this time, the finishing work is performed such that the wall surface is flat so as to cover both the heat insulating material 110-1, the sub frame 230 and the steel frame 220 as well as the heat insulating material 110-1.

The finishing treatment may be finished by applying mortar or by applying mortar and then attaching a surface material such as a gypsum board. As concrete examples, the inner surface of the wall is finished by attaching a mortar, followed by attaching a surface material such as a gypsum board, and the outer surface is finished by applying mortar to an extent that the surface strength can be secured.

In the above-mentioned finish processing, it is preferable that the outer surface of the wall proceeds as follows. Specifically, it is preferable to use glass fiber so that strength can be secured. That is, after applying a little mortar, spray a piece of glass fiber on it, and then apply mortar on it again. Further, in the case of using the glass fiber as described above, a method of laminating a glass fiber mat having a mesh structure can be used. Specifically, after a little mortar is applied, a glass fiber mat having a mesh structure is laminated thereon, and mortar is again applied on the glass fiber mat. At this time, if the roller compaction is performed, the structure becomes more dense and the smoothness is improved, which is more preferable. A method of forming a surface structure using glass fiber as described above has been disclosed in detail in Korean Patent Application Nos. 10-2002-0079546 and 10-2003-0064471.
