The present invention relates to a wall construction method of a building, and to a wall construction method of a building that can be easily constructed while having excellent thermal insulation.

In constructing a building, in recent years, a method of expressing a natural texture has been attempted to improve the quality of a building. The most common method is to cut and process natural stones such as marble into plates and attach them to the wall of the building by using a wet method using mortar. However, although the natural texture of marble can be expressed as it is, marble is fragile and difficult to handle in the process of processing, transporting and attaching the marble, resulting in high loss, large size, and in particular, mortar. There was a problem in that air and labor is increased as it must be attached by a wet process using.

In addition, a method of mixing natural stone crushed to a sand size with an adhesive and then plastering and finishing it on the wall of the building to express a natural texture has been attempted, but this method is also applied to the air and labor because the wet method is applied through plastering. There is an increasing problem. This method is inevitably used to grind the natural stone to sand size, especially for the plastering, where the grain of the natural stone is too small to express the texture of the natural stone as it is, and the quality of the product is determined by the skill of the plasterer. There was a problem of not having a smooth surface.

Meanwhile, prefabricated panels that are easy to construct are used to finish surfaces such as interior and exterior walls, ceilings, and floors of buildings. In general, prefabricated panels have a multilayer structure. Specifically, it has a structure in which a surface layer of a metal material or a plastic material and an inner heat insulating material layer or a sound absorbing material layer are laminated. Such a prefabricated panel is assembled to a steel frame as a plurality of connected to each other to form a wall of the building itself or to a surface by being assembled to a concrete wall, ceiling, floor, etc. of the building, wherein the panels are fitted or simply adhered to each other, Building structures (steel frames, concrete walls of buildings, ceilings, floors, etc.) are fastened to fixtures such as bolts and brackets.

In particular, among the prefabricated panels, sandwiched prefabricated panels having a sandwich-like three-layer structure in which a heat insulating material is filled inside and thin metal steel sheets are attached to both surfaces thereof as surface layers are used. At this time, styrofoam is mainly used as the heat insulating material filled in.

1 and 2 show a prefabricated panel according to the prior art. When described with reference to this, the prefabricated panel is generally a heat insulating material layer 10 of the middle styrofoam, and the front metal steel sheet 15 and the back metal steel sheet 20 attached to both surfaces of the heat insulating material layer 10 and forming a surface layer. It is a sandwich of 3 layer structure consisting of). And both ends of the protrusions 25 and the grooves 30 are provided so that the protrusions 25 and the grooves 30 are fitted to each other can be assembled to be assembled. In addition, as shown in FIG. 2, the protrusion 25 is predetermined in the vertical direction so as to be coupled to the steel frame 4 of a building installed vertically or horizontally on the ground by fasteners 3 such as bolts and brackets. Fixture fastening holes 27 are formed at intervals. At this time, since it is difficult to cut the heat insulating material layer 10 into a shape corresponding to the protrusions 25 and the grooves 30, the both side ends and the upper and lower ends are cut in a straight line so as to be generally rectangular. Accordingly, a predetermined space portion 33 is formed between both side ends of the heat insulating material layer 10, the groove portion 30, and the protrusion 25, and the space portion 33 is usually filled with urethane 36. . And in order to inject the urethane (36) to the end of the front metal sheet 15 and the back metal steel sheet 20 (that is, the front metal sheet 15 and the back metal sheet 20 is attached to the styrofoam In the process of forming a spaced apart portion 17 is necessarily formed.

Therefore, while fixing the prefabricated panel through the fastener fastening hole 27 of the protrusion 25, the other prefabricated panels in the left and right and up and down direction continuously while fixing the prefabricated panel, etc., the building surface can be easily constructed.

The prefabricated panels as described above have excellent insulation, can be combined in a simple assembly method, easy to construct, and widely used in buildings, general houses, as well as large buildings such as factories, warehouses, gymnasiums or public facilities for reasons of surface smoothness.

However, the prefabricated panel according to the prior art as described above has a problem in that the panel is easily damaged due to the styrofoam used as the heat insulating material layer 10 in the panel when burned, burned, melted, and corroded. That is, as shown in FIGS. 1 and 2, the metal steel sheets 15 and 20 are not attached to the side surface (the plane in the drawing), which is a part corresponding to the narrow surface, and is exposed to the outside in case of fire. As the flame enters, the insulation layer 10 is flared and there is a problem that the fire is intensified. In addition, when the heat insulating material layer 10 is exposed as described above, there is a problem that the heat insulation is inferior due to corrosion and shrinkage due to oxidation by external oxygen.

Meanwhile, as described above, in the prior art, when fastening the prefabricated panel and the building structure (steel frame, concrete wall, ceiling, floor, etc.), fasteners 3 such as bolts and brackets are used. Steel frame, concrete walls of buildings, ceilings, floors, etc.) had a problem that the panels could not be assembled flat. This will be described with reference to FIG. 3.

As shown in FIG. 3, the building structure (steel frame, concrete wall of the building, ceiling, floor, etc.), for example, the concrete wall 2 of the building is not flat or has a portion 2a protruding from the wall 2. In this case, there is a problem in that the panels 1 are not assembled flat to each other and are convex.

Meanwhile, in constructing a wall of a building, a pillar is erected with a steel frame such as an H beam or an I beam, and then bricks are laid between the steel frames or concrete is poured, and then the surface is plastered and finished with mortar. The construction method of the wall was common. However, in this case, with the increase of air and labor due to the masonry and concrete pouring of the brick, the cost of the material itself is high, and above all, there is a problem of poor insulation.

The present invention is invented to solve the problems of the prior art as described above, in constructing the wall of the building, assembling a sub-frame between the steel frame to form a plurality of empty space, and then in the empty space An object of the present invention is to provide a method of constructing a wall of a building that can be easily constructed while having excellent thermal insulation by inserting insulation and finishing the outer surface thereof.

In addition, by finishing the wall of the building with a prefabricated panel consisting of a natural stone granule layer of the surface layer, there is another object to provide a wall construction method of the building having a smooth surface while expressing the texture of the natural stone as it is.

In order to achieve the above object, the present invention provides a method for constructing a wall of a building, comprising: constructing a skeleton of a building with a steel frame, and assembling and partitioning a subframe to form a plurality of empty spaces between the steel frames; It provides a method for constructing the wall of the building comprising the step of inserting the insulating material in the empty space, and finishing the inner and outer surfaces.

At this time, it is preferable that the outer surface of the wall is finished by attaching a prefabricated panel composed of a natural stone grain layer formed by polishing a mixture of natural stone grains and a binder mixed with a surface layer.

In addition, the prefabricated panel is coated with a mixture of natural stone granules and a binder on at least one side of the glass fiber mortar layer coated with a glass fiber mortar on the heat insulating material layer, the heat insulating material layer and the glass fiber mortar layer. It is preferably made of a natural stone grain layer formed by being fixed and then ground.

In addition, the prefabricated panel is preferably the assembly member insertion hole is formed in the panel itself so that it can be assembled and coupled flat when coupled to the wall, the height adjustment assembly member is inserted and installed in the assembly member insertion hole.

Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the present invention.

Figure 4 is a cross-sectional view of the prefabricated panel according to the first embodiment of the present invention, Figure 5 is a perspective view of a heat insulating material usefully used in the present invention. 6 is a plan view of a prefabricated panel according to a second embodiment of the present invention, Figures 7 and 8 are a perspective view and a cross-sectional view for explaining the side assembly structure of the prefabricated panel of the present invention.

First, referring to FIG. 4, the prefabricated panel 100 according to the present invention is a prefabricated structure that can be assembled with an adjacent panel 100 and / or a building structure (steel frame, concrete wall of a building, a ceiling, a floor, etc.). As the panel, the surface layer having a multilayer structure and exposed to the outside is composed of the natural stone grain layer 130. Prefabricated panel 100 of the present invention is included in the present invention if the surface layer is composed of a natural stone grain layer 130, the natural stone grain layer 130 is formed on only one side of the panel 100 or to be formed on both upper and lower sides Can be. In addition, the prefabricated panel 100 of the present invention is that the surface layer is composed of a natural stone granules layer 130, therein one or more selected from the usual heat insulating material layer, sound-absorbing material layer, lightweight concrete and polymer concrete layer, etc. are laminated therein. It may have a structure.

According to a preferred embodiment of the present invention, the prefabricated panel 100 according to the present invention is a glass fiber mortar formed in the form to cover the heat insulating material layer 110 and the heat insulating material layer 110 as shown in FIG. It has a laminated structure consisting of a layer 120 and a natural stone grain layer 130 formed on at least one side of the glass fiber mortar layer 120.

The glass fiber mortar layer 120 is formed by pouring 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 a mixture of glass fiber (glass fiber), sand, cement and water, which is a heat insulating material layer (110) is not exposed to the outside ( It prevents ignition and corrosion of the 110, and imparts excellent strength and flexural rigidity to the panel 100. The sand is used fine sand, preferably silica sand. In coating the glass fiber mortar as described above on the heat insulating material layer 110, it is important that the glass fibers do not agglomerate and are evenly distributed throughout the entire area of the glass fiber mortar layer 120. At this time, as a method of uniformly dispersing the glass fiber without agglomeration, it is useful to coat the glass fiber separately while coating the mixture made of sand, cement and water without coating the glass fiber, sand, cement and water into one mixture. Can be used.

The heat insulating material layer 110 may be a heat insulating material such as styrofoam, glass wool (glass wool) or urethane foam. At this time, it is preferable that the inlet hole 115 is bored in the heat insulating material layer 110 as shown in FIG. As such, when the inlet hole 115 is drilled in the heat insulating material layer 110, the extension part 125 in which the glass fiber mortar flows into the inlet hole 115 may be provided. That is, the extension part 125 may integrate the upper and lower glass fiber mortar layers 120 and the heat insulating material layer 110 at the center to strengthen their coupling as well as to reinforce the strength of the panel 100. It is preferable.

On at least one side of the glass fiber mortar layer 120 as described above, a natural stone grain layer 130 is formed. Natural stone grain layer 130 may be formed on one side or both sides of the glass fiber mortar layer 120, Figure 4 illustrates the appearance formed on both the upper and lower sides. For reference, FIG. 10 illustrates a state in which the natural stone grain layer 130 is formed only on one side of the upper surface of the glass fiber mortar layer 120. The natural stone grain layer 130 is a mixture of natural stone grains 132 and a binder (134) is applied, fixed (cured) on the glass fiber mortar layer 120, and then the outer surface is smoothly ground will be. That is, as shown in FIG. 4, the surface is etched using a polishing machine so that the natural stone grains 132 are smoothly packed and adhered by the binder 134.

The natural stone granules 132 may be selected from various kinds of natural stones, such as marble and granite, and it is preferable to use a size of at least as narrow as possible, specifically, at least 3 mm in terms of expression of natural texture. 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 grains 132 is smaller than 3mm, the natural texture is degraded, and if larger than 15mm, the adhesion by the binder 134 is reduced, and a lot of polishing may be required to have a smooth surface. In addition, the binder 134 may be used as long as the resin has adhesiveness to fix the natural stone grains 132. For example, an acrylic resin, a urethane resin, a propylene resin, or the like may be used.

In addition, in using the natural stone grains 132, only one kind of natural stone grains 132 having the same color may be used, or various kinds of natural stone grains 132 having various colors may be mixed and used. In this case, when using various types of natural stone grains 132 mixed, different colors may be used, and various patterns may be expressed in the natural stone grain layer 130. That is, two or more kinds of natural stone grains 132 having different colors are used, for example, shapes such as letters, circles, triangles, squares, pentagons, and octagons, as well as flowers, animals, figures, crosses, bells, and birds. Birds, trees, rainbows, waterfalls, mountains, cars, airplanes, trains, buildings, plants, etc. can be represented. More specifically, as shown in FIG. 6, the character "Youngsan" uses natural black grains 132 of a black type, and the base portion except for the letter "Youngsan" is a white type of natural stone grains 132. Can be used to stand out the pattern of the letters "san".

On the other hand, the prefabricated panel 100 of the present invention is assembled, coupled to the building structure (concrete wall, steel frame, ceiling, floor, etc.) of the building in close contact with the adjacent panel 100, or panel 100 The side may have an assembly structure to be assembled and coupled to each other. Such an assembly structure may be an uneven structure or a fitting groove 151 and a fitting protrusion 152 as shown in FIG. 7. At this time, the assembly structure, that is, the fitting groove 151 and the fitting protrusion 152 is formed only on the left and right side (as seen in Figure 7) or only formed on the upper and lower side (as seen in Figure 7, that is, flat and bottom), And it is formed on the left and right side and includes both formed on the upper and lower side. Figure 7 illustrates that formed on the left and right side.

In addition, as shown in FIG. 7, the thickness h1 and h2 of the fitting groove 151 and the fitting protrusion 152 are configured to be the same size, but one fifth (five minutes) of the thickness H of the panel 100 is used. 1), 2/5, 1/3, or 2/3. In addition, as shown in Figure 8, but the thickness (h1) (h2) of the fitting groove 151 and the fitting protrusion 152 is configured in different sizes, the thickness (h1) of the fitting groove 151 is a panel ( 100) 2/3 of the thickness H, and the thickness h2 of the fitting protrusion 152 is configured to be 1/3 of the thickness H of the panel 100, so that the empty space 155, that is, the panel ( 100) an empty space 155 corresponding to 1/3 of the thickness H may be formed. In addition, the empty space 155 is used as a space into which electricity, gas, cold and hot water pipes can be inserted, or as a space into which a steel frame as a building structure can be inserted. It can be used as a means to.

When describing the preferred manufacturing method of the prefabricated panel 100 of the present invention as described above as an example. In order to manufacture the panel 100, a mold (die) is used, and the mold is preferably made of a lower mold and an upper mold. At this time, the lower mold is shaped to form the fitting groove 151 and the fitting protrusion 152 as a side assembly structure.

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

Next, while spraying (spraying) the mortar mixed with sand, cement, and water separately into the lower mold, the glass fiber is evenly sprayed separately. The reason for spraying separately without using a mixture of mortar and glass fibers is to prevent the glass fibers from agglomeration. As such, after pouring the glass fiber mortar layer 120 having a predetermined thickness in the lower mold, the mortar-impregnated heat insulating material is laminated thereon. Then, as described above, the mortar is sprayed (sprayed) on the heat insulating material and the glass fiber is evenly sprayed separately so that the glass fiber mortar layer 120 is coated with a predetermined thickness on the outside of the heat insulating material. Next, pressing the upper mold to compact the structure and at the same time have a smoothness and curing, the semi-finished product is coated with a glass fiber mortar layer 120 is coated on the surface of the heat insulating material layer (110). Then, by applying and fixing a mixture of natural stone grains 132 and a binder 134 on one or both surfaces of the glass fiber mortar layer 120, and then polishing the outer surface thereof, the natural stone grain layer having a flat and smooth surface ( 130) can be obtained.

On the other hand, the method for covering the glass fiber mortar layer 120 as described above has been presented in detail by the present inventors in the Republic of Korea Patent Application Nos. 10-2003-0064471 and 10-2003-0064471.
