The present invention is an ocher panel for building, a method for manufacturing the same and a method for constructing ocher buildings using the same, and more specifically, it is useful for comfortable living life by expressing its own effect using natural-friendly ocher, and cracks caused by dry shrinkage. Because it has little strength and durability, it is easy to transport and does not require formwork, which shortens the construction period and reduces the production cost by not adopting building materials such as insulation. The present invention relates to a manufacturing method and a construction method of ocher buildings using the same.

Conventional building structures are constructed of reinforced concrete structures using materials of rebar, cement and gravel sand, and are constructed from direct sunlight from the summer outside, radiant heat from ambient temperature, and conductive heat and cold outside air generated during the winter. In order to insulate the interior of the building, Styrofoam and glass fiber were used as insulation materials.

However, in the concrete building structures as described above, when long-term exposure in the living space due to the fine dust harmful to the human body generated from the insulating member, there is a problem that it is difficult to maintain a healthy human body by accumulating harmful gas and fine dust on the human body. There was a problem in that construction waste material was mass produced during reconstruction, causing cost and environmental pollution. Therefore, in recent years, the demand for new building materials that are harmless to the human body and meet the health aspects of modern people is increasing.

As is well known, in general, the soil wall is an indispensable building style in all countries' history, and it was a construction method using mud or the like before the solid building material using a compound such as cement was invented. Among muds, in particular, ocher soil mixed with chamotte, talc, and silica in a certain ratio is constructed as a wall or floor. Such ocher walls increase the activity of the human body by releasing germanium or far-infrared rays to promote blood circulation, etc. It was a construction method.

In particular, ocher is known to promote metabolism by activating biological cells of the human body by the release of far-infrared rays like natural ceramic materials or artificial bioceramic compositions, and as a result, it is possible to obtain effects such as blood circulation, deodorization function, It is recognized as a building material that is very useful for human body and living environment due to its dehumidification function, and the building structure using solid wood has been widely used to emphasize the interior and exterior image of homes and villages with high quality and dignity. Therefore, the role of appearance quality expression is used for the main purpose.

However, when the building structure is constructed of the above-described wood, the cost burden is large, and it is weak in waterproof, antiseptic, insect repellent, warping, and so on, and has a disadvantage in durability and wear resistance.

Traditionally, clay bricks are manufactured by soaking ocher soil in water, mixing it with finely chopped straw, and then slicing it into a frame of a certain size to make bricks and curing them. Soil brick manufactured as described above has the advantage of excellent thermal insulation, far-infrared radiation, etc., which is beneficial to the human body, and has the advantage of excellent insulation and no need to use a heat insulator, but it is weak due to its weak strength and cracks due to shrinkage during drying. There is a problem that can not be applied to high-rise building construction. That is, the ocher particles have a fatal problem in that the hydrophilicity of water is poor, so that free water (extra water) evaporates when it is dried and the yellow soil wall contracts and eventually cracks, resulting in poor durability of building materials.

Recently, after the basic frame of the building is formed of concrete, the method of processing the ocher mortar as an external finishing material is mainly used. In this case, as in the conventional concrete building, it is necessary to use an insulating material and go through a separate ocher mortar finishing process. The process was complicated and the effect of the loess was not fully exerted.

 Republic of Korea Patent Publication No. 372682 discloses a method for manufacturing the ocher wall using the steel, but the ocher wall prepared according to the present invention is very weak because only the loess is filled in the interior of the rectangular frame, the wall surface by the external impact There is a high possibility of the damage, and because it is not disclosed at all that the specific strength of the building wall can be obtained by using the specific ocher composition specifically for the interior ocher aggregate, there was a problem that it cannot be used as an actual building wall.

Therefore, the first technical problem to be achieved by the present invention is to use the natural loess, and to achieve the beneficial effect of the emission of far-infrared rays, its inherent effect, while having excellent strength, almost no cracking, and without using any heat insulator It is to provide an ocher panel for construction that can be directly applied to the construction of high-rise buildings.

In addition, the second technical problem to be achieved by the present invention, to provide a manufacturing method of the building ocher panel.

In addition, the third technical problem to be achieved by the present invention, using the ocher panel is easy to transport and do not need the formwork is not only shorten the construction period, but also reduce the production cost by not adopting the building materials such as insulation material It is to provide a construction method of ocher buildings that can be done.

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

However, embodiments of the present invention illustrated below may be modified in many different forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art. In the drawings, the size or thickness of films or regions is exaggerated for clarity.

1 is a perspective view of an ocher panel according to an exemplary embodiment of the present invention, and FIG. 2 is a cross-sectional view of the ocher panel of FIG. 1 taken along line AA ′.

1 and 2, the ocher panel 100 according to the present invention is an outer support frame formed in a square or rectangular shape by combining the metal members of the c-letter (section) arranged so that the opening is directed toward the inside. A plurality of reinforcing bars comprising a 130 and a predetermined component and is reinforced in the interior of the outer support frame and the loess mortar 120 is filled in the outer support frame, the fixed loess mortar 120 is fixed Or it characterized in that it comprises a reinforced plastic (110).

The outer support frame 130 is made of a metal member, it is preferable to have a predetermined strength in the characteristics used as the skeleton of the ocher building, for example, iron (Fe) containing about 0.12 to 0.25% carbon (C) As a mild steel, it should be of high strength, large deformation until fracture and no risk of so-called brittle fracture, which is suddenly destroyed by slight deformation to external force. The size of the outer support frame 130 is not particularly limited, but should be appropriately adjusted in a range such that the weight of the unit ocher wall portion is not too heavy, and its size and shape may be arbitrarily determined according to a pre-fabricated design drawing. The surface of the outer support frame may be a corrosion protection coating for corrosion protection.

In addition, as shown in FIG. 1, each edge of the outer support frame 130 may be coupled through a method of coupling various metal members such as oxygen welding and arc welding.

On the other hand, the inside of the outer support frame can be seen that a plurality of reinforcement or fiber reinforced plastic 110 is disposed in a net shape. Here, the used reinforcing bar is not particularly limited in the range that can be fixed to the solidified ocher mortar 120, round bar (SBC) or deformed bar (SBD) according to the provisions of KSD 3504 (bar for reinforced concrete) Preference is given to using. Here, the deformed reinforcing bar has a node and a rib (rib), has the advantage of greater adhesion to the loess mortar than circular reinforcement. In addition, although shown in the net shape in the drawings, it can be provided in a variety of shapes, such as a stripe shape or comb shape. In addition, the coupling portion 140 of the outer support frame and the reinforcing bar can be formed using a method of coupling a variety of metal materials such as oxygen welding, arc welding. On the other hand, in place of the reinforcing bar reinforced fiber reinforced plastics, in this case there is an advantage that can improve the workability by reducing the total weight of the ocher pattern.

In addition, the ocher mortar 120 is fixed by a plurality of reinforcement or fiber reinforced plastics are disposed inside the outer support frame is based on 100 parts by weight of ocher, 50 to 80 parts by weight, 10 to 30 parts by weight of silica sand 5 to 20 parts by weight of quicklime, 5 to 10 parts by weight of CSA-based expanding agent, 3 to 7 parts by weight of calcined gypsum, 3 to 7 parts by weight of pulp fiber, and 0.5 to 1 parts by weight of thickener. It is characterized by excellent durability and excellent strength because it is excellent in strength and hardly shrinkage due to drying unlike conventional ocher mortar.

The amount of the blended water should be carefully controlled in order to prevent bursting or cracking when the ocher mortar is dried. When the amount of the blended water is less than 50 parts by weight, there is a concern that the bursting occurs during drying. If you do, there is a risk of cracking during drying.

The silica sand is used to prevent this and improve the strength because there is a fear of cracking when drying when only the ocher powder is used. The silica sand component is SiO _2, which is a hydrophilic inorganic material, and thus has the ability to retain free water (excess water) generated by the ocher mortar, thereby preventing shrinkage and enhancing the strength of the ocher wall part by the pozzolanic reaction. It also plays a role. When the content of silica sand is less than 10 parts by weight based on 100 parts by weight of ocher, the effect of suppressing cracks and strength enhancing effects during drying is insignificant. It is not desirable because there is. On the other hand, the size of the silica sand particles is preferably 0.03 ~ 2 mm.

In the present invention, quicklime, CSA-based expanding agent and calcined gypsum are used in an appropriate amount to prevent cracking by compensating for shrinkage that may occur during drying of ocher mortar. That is, the quicklime, CSA-based expanding agent, and calcined gypsum can prevent the cracking of the ocher wall and increase the strength when the ocher mortar expands gently as much as the shrinkage of the ocher.

Quicklime prevents shrinkage during drying of the ocher mortar according to the present invention, and serves to improve the strength of the ocher yellow wall part through the pozzolanic reaction complexed with the SiO ₂ component of iron, aluminum and silica in ocher. When the content of quicklime is less than 5 parts by weight based on 100 parts by weight of ocher, the effect of addition is weak, and when it exceeds 20 parts by weight, the pH of the ocher mortar becomes too high and the ocher component in the ocher mortar is not preferable.

The CSA-based expanding agent used in the present invention means a calcium-sulfo-aluminate (CaO-Al ₂ O ₃ -SO ₃ ) -based expanding agent, and shrinks as the moisture evaporates during drying of the ocher mortar. The CSA-based swelling agent forms an etringite acicular crystal upon hydration, and as the crystal grows, it compensates for shrinkage because the moisture evaporates and fills the remaining pores, while also compacting the pores. Therefore, the effect of increasing the strength can also be obtained. When the content of the CSA-based swelling agent is less than 5 parts by weight based on 100 parts by weight of ocher, the addition effect is insignificant, and when it exceeds 10 parts by weight, it is not preferable because the amount of ocher in the loess mortar becomes relatively small.

 Plasma gypsum used in the present invention serves as a swelling agent, and when hydrated is formed by hydrated gypsum, it has an effect of compensating shrinkage of ocher mortar. Particularly, in the case of the quicklime produced by hydration of quicklime used in the present invention, calcium carbonate and water are reacted with carbon dioxide to generate calcium carbonate and water, and thus, shrinkage may be reduced as a whole.

In addition, the pulp fibers used in the present invention serves to prevent cracking after drying of the ocher mortar and thereby increase the strength. The pulp fiber may be used without particular limitation as long as it is commonly used in the art, and usually has a length of about 0.5mm. When the content of the pulp fiber is less than 3 parts by weight based on 100 parts by weight of ocher, the effect of addition is weak, and when it exceeds 7 parts by weight, it is not preferable because the cohesive force of the ocher mortar may drop.

Finally, the thickener used in the present invention increases the cohesive force between the ocher mortar and the plurality of rebars by imparting viscosity to the ocher mortar to improve the cohesion and cohesion between particles, and enhances the strength of the ocher wall during drying. . It is preferable to use a cellulose or starch thickener as the thickener, but when the content of the thickener is less than 0.5 parts by weight based on 100 parts by weight of ocher, the effect of addition is weak, and when it exceeds 1 part by weight, workability may be deteriorated. .

On the other hand, a portion of the side of the outer support frame used in the present invention may be formed with a V-shaped yaw portion, and the other portion is formed with an iron portion engaging with the recess portion. This is to increase the ease of construction and the bonding strength between the outer support frame when constructing the ocher panel according to the present invention. That is, when constructing the ocher panel according to the present invention, the recessed portions and the iron portions are fixed to each other between adjacent ocher panels, thereby improving workability and increasing bonding strength.

Next, the manufacturing method of the above-mentioned building ocher panel is demonstrated.

The manufacturing method of the ocher panel for building according to the present invention is formed by combining the ends of the metal member having a c-letter cross-section with each other, the overall shape of which is square or rectangular, and forms an outer support frame with an opening facing inward. Making; Arranging the outer support frame on a bottom plate on which ocher mortar is poured and placing a plurality of reinforcing bars or fiber-reinforced plastics inside the outer support frame; 50 to 80 parts by weight of the blended water, 10 to 30 parts by weight of silica sand, 5 to 20 parts by weight of quicklime, 5 to 10 parts by weight of CSA-based expanding agent, 3 to 7 parts by weight of plaster, and 3 to 3 pulp fibers. Forming an ocher panel by filling ocher mortar including 7 parts by weight and 0.5 to 1 part by weight of thickener in a frame part space formed of the inside of the outer support frame and the plurality of reinforcing bars or fiber-reinforced plastics; Compressing the loess mortar filled with the loess mortar by a roller to infiltrate the filled loess mortar evenly into the inside of the outer support frame to secure a flatness of the loess mortar; And drying the crimped ocher panel to increase its strength.

First, in order to form an outer support frame, the ocher panel 100 cuts two pairs of metal members having a c-letter cross section, each of which has an equal length, in which the openings are arranged toward the inner surface. The cutting method may use a conventional cutter such as a grind and may use high temperature and high pressure oxygen welding or high voltage arc welding.

Further, each of the two pairs of each piece is arranged such that the pieces of the same length face each other and are joined by the above-described welding method.

Next, the outer support frame is disposed on the bottom plate, the bottom plate is filled with ocher mortar inside the outer support frame and the surface is rolled to prevent the departure of the ocher mortar during rolling (rolling) for the planarization described below Place it on the opposite side of the board and fix it tightly. In addition, the bottom plate is not particularly limited in the range that does not leave the ocher mortar during filling and rolling of the ocher mortar is provided in the shape of a flat substrate. Next, a plurality of reinforcing bars or fiber-reinforced plastics in a mesh shape inside the outer support frame is coupled to the inside of the outer support frame. In case of using reinforcing bar, welding method can be used. In case of using fiber reinforced plastic, a separate fastener can be used.

Next, after filling the inside of the outer support frame loess mortar according to the present invention, the filled loess mortar is formed in the form of a panel, which is by rolling. That is, the outer support frame is fixed to the upper portion of the bottom plate and filled with loess mortar therein, and the roller is applied to the upper portion of the outer support frame by rolling. The ocher mortar filled in the ocher panel is flattened by the roller.

Next, drying is carried out for the strength of the flattened ocher mortar, and it is desirable to allow solidification and curing within 48 hours in consideration of mass productivity and handleability at the same time.

On the other hand, Figure 3 is a construction sequence diagram showing a construction method of the ocher building according to another embodiment of the present invention.

Referring to Figure 3, the construction method of the ocher building step of installing a plurality of ocher panels on the upper portion of the foundation (step S1) and the step of combining the plurality of ocher panels to form an integral ocher wall portion (step S2) And it can be seen that the step of forming a ceiling on the upper end of the ocher wall portion (step S3) and the step of plastering the ocher mortar using a mesh network to the ocher wall portion (step S4).

First, in step S1, the ocher panel is vertically mounted as the wall design of the predetermined architectural drawing on the upper part of the foundation. 4 is a plan view showing a plurality of ocher panels vertically erected vertically coupled to each other according to an embodiment of the present invention, Figure 5 is a cross-sectional view taken along the line BB 'of FIG.

4 and 5, it is understood that the plurality of ocher panels are erected vertically on the upper part of the base part 420 to be combined with each other to form the ocher wall parts 410 and 510 according to the design of the ocher wall parts of a predetermined construction drawing. Can be. In addition, the ocher panel can be erected vertically due to the ocher mortar load placed therein as well as the self-load of the c-shaped metal member, and moreover is firm because it combines a plurality of ocher panels with each other by welding or the like.

On the other hand, Figure 6 is a partial view of vertically standing ocher panel according to another embodiment of the present invention, by forming the insertion portion 310 formed to have a predetermined depth in a straight line to make the ocher panel 320 vertically Of course, it may be inserted into the insertion unit 310. That is, when the foundation 300 is formed, the ocher panel 320 may be inserted to form an insertion portion 310 having a predetermined depth so as not to fall down by external vibration or external force. When the part is formed of concrete, the insertion part is formed in a shape corresponding to the outer shape of the ocher panel to be inserted. However, the present invention is not limited thereto, and the ocher panel may be temporarily fixed by applying support members which are commonly used on both sides of the ocher panel. Here, the base portion 300 is a structure for the purpose of securely fixing the weight of the building and the various loads applied to it on the ground and to prevent the obstacles such as settlement, inclination, movement, deformation, vibration, or the like exceeding the allowance of the building. Types of such structures include independent foundations, composite foundations, stem foundations, continuous foundations, and all-weather foundations.The type and size of the structures can be determined by the upper load, bearing capacity, terrain bearing capacity, and the like. ) Can be used.

On the other hand, in the step S2, the plurality of ocher panels are coupled to each other so as to be fixed to each adjacent side of each of the plurality of ocher panels to form an integral ocher wall portion, which is a plurality of insertion portion formed in the base portion To join the panels. The formation of the ocher wall portion is not particularly limited as long as the adjacent ocher panels can be fixed to each other, but preferably, the adjacent ocher panels may be fixed by oxygen welding, arc welding, or the like. On the other hand, as already mentioned, by forming an uneven portion on the side of the adjacent ocher panel to interlock with each other can form a more robust ocher wall portion.

In addition, looking at the step S3, the top portion of the ocher wall portion consisting of a plurality of ocher panels to cover the ceiling member to cross the erected direction to form an indoor sealed space.

Referring to FIG. 5, the ceiling member is disposed perpendicular to the ocher wall portion 510 formed by being coupled to an ocher panel according to a pre-designed drawing. The ceiling member may be provided as a second base portion 530 and a support portion 520. Here, the second base portion 530 is the same as or similar to the base portion 300 of FIG. 6. The support part 520 is installed to withstand the load of the second foundation part 530. In FIG. 5, the supporting portion is stacked below the second basic portion, but may be provided inside the second basic portion within a range that can withstand the load of the second basic portion.

On the other hand, when the ocher wall portion 510 formed by a plurality of ocher panels is a single-layer design, the ceiling member becomes a ceiling and a substructure of the roof, but in the case of a multi-layer design, the second foundation part ( 530 is formed. In addition, the support 520 may be provided as a so-called deco panel, the deco panel may have a plurality of irregularities of a conventional iron plate, as can be seen in FIG. These uneven parts support the added load. As described above, in the case of a multi-layer design, the multi-layer ocher building may be formed by repeating the steps S1 to S3. That is, the plurality of ocher panels may be stacked on top of the ceiling member, and a plurality of ocher panels may be vertically formed by forming an insertion groove having a predetermined depth in a straight line in the second base portion 530 of the ceiling member. We can see that you can build it.

On the other hand, in the construction of the single-layer and multi-layer ocher building, each layer may be composed of a single ocher panel or a multi-stage ocher panel, which will be described with reference to FIGS. 7 and 8.

7 is a view showing the ocher wall portion by one end of the ocher panel according to another embodiment of the present invention, Figure 8 is a view showing the ocher wall portion by the two-stage ocher panel according to another embodiment of the present invention.

Referring to FIGS. 7 and 8, a plurality of ocher panels 620 forming an ocher wall part with one end perpendicular to the upper part of the base part 610 forms a single layer, and is formed as an upper part of the plurality of ocher panels 620. Two basic portions 640 are formed.

In addition, it can be seen that another ocher panel 650 is erected vertically on the second base portion 640.

On the other hand, as can be seen in Figure 8, a plurality of ocher panels (720, 730) forming the ocher wall portion in two stages perpendicular to the top of the base portion 710 forms a two-layer, the plurality of ocher panels ( The second base portion 740 is formed on the upper portion of the 730.

In addition, it can be seen that another ocher panel 750 is vertically erected on the second base portion 740. 7 and 8, although the plurality of ocher panels are shown in a single layer and two layers, the present invention is not limited thereto, and the ocher panels may be laminated in multiple layers within a range of easy transportation and simple construction.

Finally, looking at the step S4, by covering the mesh network on the inner surface and the outer surface of the ocher wall portion is a step of plastering and drying the ocher mortar for plastering. Plastering ocher mortar used in this step may be used without particular limitation as long as it is commonly used in the art.

The mesh net is a net-shaped plastic material, which is used for solid plastering, and the plastic material does not need to be particularly limited within a range in which ocher mortar for plastering may be plastered on the ocher panel.

On the other hand, the coupling portion of the plurality of ocher panels constituting the ocher wall portion is formed at almost right angles, until the ocher is cured, the adhesion of the ocher mortar to the portion formed at right angles is low, less hardened when plastering In order to prevent the ocher mortar from detaching and to form a smooth appearance at the corners, the metal plate having a plurality of perforations is bent and fixed in advance at almost right angles, and the ocher mortar is plastered on the metal plate. This can be seen through FIG. 9, which is a view of plastering a metal plate having a plurality of perforations using ocher mortar according to another embodiment of the present invention. Referring to FIG. 9, a plurality of ocher panels 900 are coupled to each other to form an integral ocher wall portion, and the side surface of the ocher wall portion is plastered with ocher mortar 930. Here, the ocher mortar 930 is plastered after the metal plate 910 having a plurality of perforations 920 is fixed to surround the edges of the ocher panels joined at the corners of the ocher wall. Therefore, the ocher mortar 930 is filled into the perforated part 920, and thus the adhesion force with the ocher wall part is increased as a whole. Instead of the metal plate 910, a corner finish made of a metal net may be used.

The exterior of the ocher building manufactured according to the present invention may be treated with plastering ocher mortar, but may be finished with plastering concrete mortar, or tile or other exterior wall finishing material in consideration of waterproofing.

10 is an ocher building constructed by the construction method of the ocher building according to the present invention. Referring to FIG. 10, the exterior of the ocher building is treated with plastering ocher mortar to not only have a neat appearance, but also has excellent strength and durability because there is almost no crack due to dry shrinkage using the ocher mortar according to the present invention. Can be.

Hereinafter, the present invention will be described in more detail with reference to preferred examples and test examples, but the present invention is not limited thereto.

As described in Table 1, the ocher mortar used in the ocher panel according to the present invention has superior compressive strength after drying as compared with the conventional ocher mortar, and because there is no shrinkage during drying, there is no cracking phenomenon and thus durability is excellent. By using only the ocher panel according to the present invention alone, it is possible to easily manufacture the ocher building excellent in thermal insulation and durability. On the other hand, in the case of using the fiber-reinforced plastics inside the outer support frame can improve the workability because the weight of the ocher panel itself can be reduced.

As described above, the present invention is useful for comfortable living life by expressing its inherent effect by using natural-friendly ocher, and excellent in strength and durability because there is almost no crack due to dry shrinkage, and its transportation is easy. Since no formwork is required, the construction period can be shortened and production costs can be reduced by not adopting building materials such as insulation.
