The present invention relates to a building panel manufacturing apparatus, a method of manufacturing a building panel using the same, and a building panel manufactured by the method, wherein a surface fine layer having upper and lower reinforcing meshes of a porous lightweight panel is simultaneously formed, The present invention relates to a construction panel manufacturing apparatus capable of stacking a large number of construction panels produced without damaging a surface smooth layer by automatically attaching a protective paper to a surface thereof, a method of manufacturing a construction panel using the same, and a construction panel manufactured by the method.

Generally, a variety of building materials are used for interior and exterior materials of a building in order to provide external beauty and insulation of buildings. Foam synthetic resins such as foamed styrene foam, foamed urethane foam, and foamed phenol foam are widely used as such heat insulating building materials.

However, the conventional heat insulating building material as described above is not only a fire hazard, but also a noxious gas is released when a fire occurs. Recently, research on an architectural panel made of inorganic material free from the risk of fire has been actively carried out.

Natural granite is widely used as a building interior and exterior material to prevent the risk of fire as above, for example, natural building panels. However, since natural granite such as Oia must be quarried in nature, there is a problem that the natural environment is damaged However, excessive use of reinforcing bars and cement to fix it by its own load has raised the problem that the cost of construction of the frame increases. Particularly, natural granite has no heat insulating performance, and the inner and outer walls must be separately heat-sealed.

In order to solve the above problems, a construction panel having a structure in which both sides of the foamed concrete are wrapped with a cement board is used as interior and exterior materials for construction. However, such a construction panel is formed by simply joining the completed foamed concrete and the cement board, The cement board is detached from the both sides of the concrete, or the cement board is broken, resulting in a problem that the cement board can not be utilized as a building material.

In particular, a conventional building panel for interior and exterior use mainly made of foamed concrete requires a lot of workforce and work space because it requires the cement board to be attached to the foamed concrete panel by the manual work of the operator, .

Further, during the mesh attachment step, the lightweight panel is supported and transported by the first mortal shell 300 and the second mortal shell 500. That is, at the mesh attaching step, since the inner mortar layer 12 formed on the upper / lower surface of the light panel is uncured, the lightweight panel is supported by the upper and lower contact rollers 412 and 422 of the mesh installation part, The first mortar can be supported and transported by the first mortal shell 300 and the second mortar shell 500 so that damage to the inner mortar layer 12 does not occur, .

The outer molar layer 14 and the inner molar layer 12 are integrated with each other via the reinforcing mesh 13 because the inner molar layer 12 remains uncured at the secondary molar application step The surface smooth surface layer 16 is formed.

The protection sheet attaching step is a step of attaching the protective paper 15 so that the building panel 10 is transported and discharged by the discharge unit without damage while protecting the surface smooth surface layer 16 in an uncured state. The protective paper 15 wound on the lower drums 611 and 621 is automatically released by the conveyance force of the light panel and the surface of the outer mortar layer 14 in the uncured state of the light panel, And is installed. At this time, the protective paper 15 is uniformly laid on the surface of the outer mortar layer 14 uncured by the upper and lower rollers 612 and 622.

The sensing step is a step of sensing the presence or absence of the light weight panel with respect to the cutting position 920 by the sensor unit 910. The sensing unit 910 senses the position of the light weight panel The lightweight panel having passed through the protective paper laying portion 600 is fed to the discharge portion 900 through the through hole 741 formed in the support frame of the cutting portion via the second conveying roller portion 800. [ The position of the lightweight panel where the light panel is placed on the discharge portion 900, that is, the position of the lightweight panel moved onto the discharge portion 900 and sensed by the sensor portion 910, is set at a cutting position 920 ).

The cutting step is a step in which the reinforcing mesh 13 and the protective paper 15, which are connected to each other between the light weight panels 11 by the cutting part 700, are cut to fit the respective light panel sizes. (Front light-weight panel 10a) that has reached the cutting position through the through-hole 741 of the support frame by the operation of the first transfer roller unit 800 and the second transfer roller unit 800, The front end lightweight panel 11a and the rear end lightweight panel 11b are separated by cutting the reinforcing mesh 13 and the protective paper 15 connected to the other light weight panel (rear end lightweight panel 10b)

[

When the sensor unit 910 detects the arrival of the lightweight panel at the cutting position 920, the upper and lower cutters 710 and 720 are simultaneously operated to guide the lightweight panel along the guide rail 730. [ Width direction W to cut the reinforcing mesh 13 and the protective paper 15 between the leading end lightweight panel 11a and the rear end lightweight panel 11b. At this time, the inner and outer mullion layers 12 and 14, which are applied to the front lightweight panel 11a and the rear lightweight panel 11b and are uncured, are cut by the upper and lower cutters 710 and 720, do.

In the continuous operation step, the front end lightweight panel 11a separated from the rear end lightweight panel 11b by the cutting step is transported to and discharged from the outside by the discharge portion 900, The rear lightweight panel 11b which is located is transported and supplied to the cutting position 920 by the operation of the panel supplying part 100 and the first and second molten supplying parts 300 and 500 so that the reinforcing mesh 13 and the protective paper 15 The cutting is performed. That is, the supply and cutting of the light panel are continuously and repeatedly performed.

In addition, the mortar to be coated by the first and second mortal shells 300 and 500 may be a known mortar used for panel finishing.

In addition, the present invention can be applied with a functional mortar containing an anti-alkaline agent by the first and second mortal shells 300 and 500. When the functional mortar is applied to the upper and lower surfaces of the lightweight panel, The building panel 10 is provided with functionalities such as water repellency, water resistance, corrosion resistance, impermeability, anti-alkalinity, whitening phenomenon and the like by the functional mortar as well as durability and strength enhancement effect by the surface smooth layer 16.

The functional mortar is prepared by adding 3 to 20 parts by weight of an anti-alkaline agent to 100 parts by weight of cement, wherein the anti-alkaline agent comprises 20 to 35 wt% of reactive silicon dioxide, 15 to 25 wt% of a soluble metal soap- metakaolin, 3 to 10 wt% of a polycarboxylate reducing agent, 1 to 5 wt% of sodium hexametaphosphate, and 15 to 30 wt% of water (distilled water).

The reactive silicon dioxide generates CSH (CH + SC-SH) by the reaction of the cement with the excess calcium hydroxide generated in the hydration reaction, thereby reducing the amount of calcium hydroxide in the concrete and simultaneously blocking the capillary passage Thereby reducing the whitening phenomenon due to the surface movement of the calcium hydroxide. Such a reactive silicon dioxide may be a reactive amorphous silica powder, for example, a known reactive silica powder.

When the reactive silicon dioxide is added in an amount of less than 20 wt%, the phenomenon of reduction of the whitening phenomenon is reduced. When the reactive silicon dioxide is added in an amount exceeding 35 wt%, the viscosity becomes high when mixed with water, The characteristics are not only deteriorated but also there is little difference in the effect of preventing the improvement of the strength and the whitening phenomenon, and it can act as an element of the alkali aggregate reaction.

The soluble metal soap-based waterproofing agent is melted in water, and is sufficiently mixed with the mortar so as to be uniformly distributed not only in the surface of the molded concrete structure but also in the interior thereof, thereby imparting excellent water resistance.

The soluble metal soap-based water repellent agent is prepared by heating water to 50 to 60 캜, dissolving sodium carbonate, sodium fluoride, and potassium hydroxide in water to produce a first mixed solution ; A second step of adding stearic acid, which is heated and dissolved in the first mixed solution, and mixing the same to form a liquid soap; A third step of cooling the liquid soap to 25 to 30 캜; After the third step, ammonia water is added and mixed and stirred.

Wherein the soluble metal soap-based waterproofing agent comprises 3 to 6 wt% of stearic acid, 0.1 to 0.5 wt% of sodium carbonate, 2 to 6 wt% of ammonia water, 0.001 of sodium fluoride By weight of potassium hydroxide and 0.5 to 1.2% by weight of potassium hydroxide, and 100% by weight of the balance of water. Examples of the surfactant include alkaline substances such as sodium carbonate and potassium hydroxide, It is composed of Water soluble soap by chemical reaction of stearic acid.

That is, the soluble metal soap-based waterproofing agent is a water-soluble metal soap-based waterproofing agent which is produced by adding stearic acid as a fundamental basic material and by adding potassium hydroxide, sodium carbonate, sodium fluoride and aqueous ammonia having strong alkalinity to progress the deep saponification of strong acid and strong alkali, And availability.

The stearic acid is a saturated fatty acid having a carbon number of 18 and has a function of improving the waterproofness by improving the waterproof property. When the content is less than 3 wt%, the waterproof property is deteriorated. When the content is more than 6 wt% As a result, not only the workability is deteriorated but also the adhesion with concrete is lowered.

When sodium fluoride (NaF) is added in an amount of more than 0.01 wt%, the denseness of the waterproof film tends to deteriorate. When the water content is less than 0.001 wt%, the waterproof film Hardness and tightness can not be ensured. Therefore, it is added within an appropriate range. Further, the sodium fluoride (NaF) has a function of promoting the hydration reaction of the cement by dissolving in water to emit strong alkalinity.

The aqueous ammonia solution has a function of proceeding a secondary irreversible saponification reaction as a strong acid and adjusting an appropriate pH value. At this time, the aqueous ammonia solution may be used at a concentration of about 15 to 30%, preferably about 20 to 25%, more preferably about 22 to 23%.

In the soluble metal soap-based waterproofing agent, the soap liquid not only forms a hydrophobic adsorption layer between particles of cement hydrate, aggregate and cement particles not yet hydrated, but also forms an insoluble matter to fill micropores The capillary passage is blocked to impart water repellency, which is a property that water does not penetrate well, and consequently, the strength of the concrete structure is not deteriorated.

In other words, the known metal soap-based waterproofing agent slows the hydration speed of the cement to reduce hydration of the cement, so that the strength of the concrete structure is lowered correspondingly. However, the soluble metal soap- The strength is not lowered.

In addition, a conventional metal soap-based waterproofing agent, especially a metal soap-based waterproofing agent using calcium stearate, has hydrophobicity, and when the concrete structure is mixed with the mortar to form a concrete structure, However, if it exceeds the thickness of a thin layer (for example, about 3 mm), the concentration of the stearate which is polymerized in the waterproof mortar becomes very low or almost not so that the waterproofing property is insignificant, The waterproof effect on the concrete structure is very unstable because of the limited waterproofness, which makes it difficult to apply it on site.

That is, the molded concrete structure is generally cut and arranged in various sizes according to the site conditions. However, when a molded concrete structure is cut by adding a known metal soap-based waterproofing agent, a polymer of metal soap It is insignificant or does not exist and the waterproof property is deteriorated.

On the contrary, since the soluble metal soap-based waterproofing agent according to the present invention is melted in water and is sufficiently mixed with the mortar to uniformly distribute not only the surface of the molded concrete structure but also the inside of the molded concrete structure, Excellent waterproofing is also imparted to the cut surface of the structure.

In addition, the soluble metal soap-based waterproofing agent can function as a retarder to delay the initial reaction at the time of mixing, so that it is possible to increase workability and quality stability by increasing the pot life without addition of water to the summer season, And functions to increase insoluble interfacial adhesion due to the solidification reaction with the waterproof layer which is the surface layer.

In addition, the soluble metal soap-based waterproofing agent not only improves the denseness of the mortar due to excellent permeability, but also has a function of preventing the occurrence of whitening by reducing the adsorption of water by water repellency.

Further, the soluble metal soap-based waterproofing agent has a dispersing property to evenly disperse the heterogeneous components, and also has a function of improving the dispersibility of reactive silicon dioxide and meta-kaolin.

The metakaolin penetrates into the mortar and concrete to react with the cement component to impart water resistance, thereby reducing whitening. That is, the meta-kaolin is mainly composed of highly active aluminum oxide (Al ₂ O ₃ ) and silicon dioxide (SiO ₂ ), and aluminum oxide and silicon dioxide are mixed with calcium hydroxide (Ca OH) ₂ ) to generate cement stone, thereby blocking the capillary passage and improving the water resistance.

If the amount of the meta kaolin is less than 20 wt%, the effect becomes insignificant and the waterproof performance is deteriorated. If the amount of the meta kaolin is more than 30 wt%, the hydrate is excessively used and the strength of the concrete structure Therefore, it is added in the range of 20 to 30 wt%. It is preferable that such a methacrolein has a specific surface area of 5,000 to 8,000 cm < 2 > / g.

The polycarboxylate is a water reducing agent and a superplasticizer for exhibiting dispersing ability and has a function of reducing the whitening phenomenon by reducing moisture in the mortar and concrete.

The polycarboxylate not only improves the workability of the concrete but also significantly reduces the weight ratio of water and cement in the concrete to remarkably reduce the internal pore volume of the cement stone to thereby improve the compactness and compressive strength Function.

When polycarboxylate is used in an amount of less than 3 wt%, the dispersibility is not sufficiently exhibited and the reactivity of the polycarboxylate is low. When the polycarboxylate is mixed in an amount of more than 10 wt%, the economical efficiency is lowered. Do.

In addition, the polycarboxylate imparts fluidity of the whole material, improves the mixing power and reduces the amount of water mixed to reduce the loose pores by closely adhering the layers, thereby imparting water resistance, The height has a function for enhancing the function and the strength.

The sodium hexametaphosphate promotes the reaction of reactive silicon dioxide by spreading the reaction heat generated by the reaction evenly throughout the mortar. That is, the sodium hexametaphosphate has a function of promoting a reaction between reactive silicon dioxide and calcium hydroxide to prevent an aggregate alkali reaction due to unreacted silicon dioxide. In addition, sodium hexametaphosphate has an effect of improving dispersibility.

Due to the effect of the sodium hexametaphosphate, reactive silicon dioxide of about 250 to 400 mesh, which has not been practically usable in the past, can be added.

In addition, the sodium hexametaphosphate is well soluble in water to exhibit alkalinity, and when applied to an aqueous solution, has a very strong dispersing property, peptizing property, ionic increasing ability, and strong moisture absorption ability.

In addition, the sodium hexanetaphosphate (NaPO ₂ ) ₆ itself has an excellent ability to form a complex with calcium, and the aqueous solution contains Ca ²⁺ , Mg ²⁺ , Ba ²⁺ , Cu ^{2 +} , Fe ^3+, etc., and blocking the activity of the ions.

In addition, the sodium hexametaphosphate forms a coating on the surface of the concrete structure. The coating formed on the surface has a function of preventing corrosion of concrete by blocking chlorine ions (Cl < ^- >) in seawater.

When sodium hexametaphosphate is added in an amount of less than 1 wt%, the effect of promoting the reaction, improving the dispersibility and preventing corrosion is insignificant. When the amount of sodium hexametaphosphate added is more than 5 wt%, excessive complexing is formed, Since the reaction rate is lowered, it should be added within an appropriate range.

The anti-alkaline agent as described above may be added in the order of reactive silicon dioxide, soluble metal soap-based waterproofing agent, metakaolin, polycarboxylate superplasticizer, sodium hexametaphosphate, water (distilled water) Mixed into a high-speed disperser, and mixed uniformly to form a milky white paste,

When mixed with cement to form a concrete structure, it reacts with the calcium hydroxide generated in the hydration process of cement to reduce the amount of calcium hydroxide produced, and at the same time, the calcium hydroxide moves to the surface, do.

In addition, since the anticalculus agent produces high strength microcrystals by the reaction with calcium hydroxide, durability and compressive strength of the mortar and the concrete structure are improved by about 10 to 15% A film is formed to reduce the whitening phenomenon due to migration to the surface of calcium hydroxide.

Particularly, the anti-alkaline agent has the property of continuously absorbing calcium hydroxide generated in continuous hydration of cement even in an environment where it is wet and eroded by rainwater, so that the durability of the concrete structure can be stably secured.

Further, the anti-alkaline agent rapidly lowers the alkali ion concentration through the ion exchange, suppresses the alkali reaction with the active aggregate, effectively removes the alkali aggregate reaction between the cement mortar and the concrete structure, and mixes with the mortar and the concrete structure The porosity and porosity of the mortar and concrete structures are changed to ensure the durability of the structure.

In addition, the anticalculus agent may include reactive silicon dioxide, a soluble metal soap-based waterproofing agent, metakaolin, polycarboxylate, sodium hexametaphosphate, and water (distilled water) It is equipped with a function to prevent corrosion of concrete by forming a waterproof coating on the surface of the waterproof layer and blocking penetration of chlorine ion (Cl ^- ) of seawater.

The anti-alkaline agent can spray coat the surface of the molded concrete structure. When the anti-alkaline agent is spray coated on the concrete structure, the anti-alkaline agent penetrates up to about 100 to 150 mm to impart excellent water repellency and waterproofness. Thereby increasing liquid impermeability and corrosion resistance.

When the functional mortar containing the anti-alkaline agent as described above is applied to the upper / lower surface of the lightweight panel, by the complex reaction of the cement with the alkali-soluble agent containing the soluble metal soap-based waterproofing agent, meta kaolin and reactive silicon dioxide, The denseness of the panel surface smooth layer 16 is improved, and the capillary passage is reduced to prevent the formation of whitening or whitening.

In addition, the calcium hydroxide generated by the continuous hydration of the cement is absorbed by the anti-alkaline agent, the surface movement of the calcium hydroxide is prevented by the water reduction, and the penetration of moisture is blocked by the waterproof property, 16 of the building panel 10 can be stably secured.

The building panel 10 manufactured by the above manufacturing method has the surface smooth layer 16 on the upper and lower surfaces 11a and 11b with the protection sheet 15 attached to the light panel 11 as a center The surface fine matte layer has a structure in which the inner mortar layer 12, the reinforcing mesh 13 and the outer mortar layer 14 are sequentially laminated on the upper and lower surfaces 11a and 11b.

In the manufacturing method according to the present invention, a plurality of lightweight panels are closely contacted with each other from the panel supply unit 100 to the cut position 920 of the discharge unit to be fed and fed in a line, and the first and second mortal shells 300 and 500 The reinforcing mesh 13 is laid by the mesh laying portion 400 and the protective sheet 15 is laid by the protective sheet laying portion 600 in succession. 920 are separated from the other lightweight panels by the cutting portion 700, and thus the waste of the mortar to be applied and the reinforcement mesh to be laid and the protective paper are not wasted The manufacturing time of the building panel 10 is shortened, and mass production of the product is achieved.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
