Description

노출 콘크리트 패널 제조방법Manufacturing method of exposed concrete panel
본 발명은 노출 콘크리트 패널을 제조하는 방법에 관한 것으로, 더욱 상세히는 건물 외벽에 설치되어 노출되는 콘크리트 패널을 불량발생없이 견고하게 제조할 수 있도록 개선한 노출 콘크리트 패널 제조방법에 관한 것이다. The present invention relates to a method for manufacturing an exposed concrete panel, and more particularly, to an exposed concrete panel manufacturing method improved to be able to manufacture a concrete panel exposed to the exterior wall of the building firmly without failure.
일반적으로 콘크리트 패널은 외부노출되는 전면이 깔끔하게 마감되도록 콘크리트 소재로 사각판재상으로 성형되는 건축 마감재로서, 강도, 내구성이 우수할 뿐만 아니라, 외관도 수려하므로, 건축용 외장재로서 각광을 받고 있다.In general, a concrete panel is a building finishing material that is molded into a square plate of a concrete material so that the front surface of the exterior is neatly finished, it is not only excellent in strength and durability, but also beautiful in appearance, and thus has been in the spotlight as a building exterior material.
이러한 콘크리트 패널은 주택이나 빌딩과 같은 건축물의 벽체에 별도의 정착구를 이용하여 연속하여 시공되어야만 하기 때문에 규격이 일정함은 물론 성형제조된 패널규격은 설계시 규격과 정확하게 일치되어야만 한다. Since these concrete panels must be constructed continuously using separate anchorages on the walls of buildings such as houses or buildings, the standard is not only constant but also the molded panel specifications must be exactly the same as the design.
또한, 콘크리트 패널의 특성상 표면 질감은 자연스러워야 하며 패널 측면에는 콘크리트 성형시 발생하는 물샘자국과 같은 얼룩이 없어야 한다.In addition, due to the characteristics of the concrete panel, the surface texture should be natural, and the side of the panel should be free of stains such as water marks generated during concrete molding.
그리고, 건물 벽체 시공시 작업자의 취급 및 운반이 용이하도록 얇은 두께로 이루어져 경량화함은 물론 외력에 의한 크랙 및 파손되지 않도록 충분한 강도를 구비해야만 한다. In addition, the construction of the building wall must be made of a thin thickness to facilitate the handling and transport of the worker, and should be provided with sufficient strength so as not to be cracked and damaged by external force.
한편, 대한민국 공개특허 2009-0062535호(2009.06.17. 공개일)에는 건축물의 표면마감재로 사용되는 콘크리트 패널을 제조하는 방법이 개시되어 있다. On the other hand, Republic of Korea Patent Publication No. 2009-0062535 (2009.06.17. Publication date) discloses a method for manufacturing a concrete panel used as a surface finishing material of the building.
이는 단순히 상부가 개방된 형태를 갖는 몰드에 콘크리트를 타설하고, 타설된 콘크리트를 양생하여 콘크리트 패널을 제조하는 것이다.This is simply to cast concrete in a mold having an open top, and to cure the poured concrete to produce a concrete panel.
그러나, 이러한 종래기술은 콘크리트 패널을 제조하는 공정상 상부로 개방된 몰드로부터 타설된 후 경화된 콘크리트 패널을 분리이탈하는 것이 용이하지 않을 뿐만 아니라 콘크리트 타설 전에 작업자가 몰드의 내부면에 탈형유를 고르게 도포해야만 하기 때문에 탈형시 패널의 표면이 파손되어 제품수율을 저하시키고, 작업자의 작업부하를 가중시키는 문제점이 있었다. However, this prior art is not only easy to separate and detach the cured concrete panels after being poured from the mold open to the upper part in the process of manufacturing the concrete panels, but also allows the operator to evenly apply the demolding oil to the inner surface of the mold before the concrete is poured. Since it has to be applied, the surface of the panel is damaged when demolding, which lowers the product yield and increases the worker's workload.
또한, 몰드로부터 분리된 콘크리트 패널을 건조하여 양생하는 공정에서 패널의 전면과 후면간의 밀도차이에 의해서 패널이 전면측으로 휨변형하게 되고, 이러한 휨변형이 과도하게 되면 시공이 불가능하여 폐기처리해야만 하는 제품불량을 초래하였다. In addition, in the process of drying and curing the concrete panel separated from the mold, the panel is warped to the front side due to the difference in density between the front and rear surfaces of the panel. If such warpage is excessive, the construction is impossible and the product must be disposed of. Resulted in a defect.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 그 목적은 몰드로부터 성형된 콘크리트 패널을 파손없이 탈형할 수 있고, 몰드에 충분한 진동을 부여하여 제조되는 콘크리트 패널의 표면에 고유한 질감을 자연스럽게 표현할 수 있는 노출 콘크리트패널 제조방법을 제공하고자 한다. Accordingly, the present invention is to solve the above problems, the object is to demould without demolishing the concrete panel molded from the mold, giving a sufficient vibration to the mold has a unique texture on the surface of the concrete panel produced It is to provide a method of manufacturing exposed concrete panels that can be expressed naturally.
또한, 본 발명의 다른 목적은 콘크리트 패널의 모서리부에 발생하는 물샘자국을 근본적으로 방지할 수 있는 한편, 성형된 콘크리트 패널을 휨변형없이 건조할 수 있는 노출 콘크리트 패널 제조방법을 제공하고자 한다.

In the mold preparation step, the bottom surface and the side are closed, and the upper part to which the concrete is supplied is prepared by providing a mold 100 having an open cavity to a work object not shown.
이러한 몰드(100)는 도 2 내지 도 4에 도시한 바와 같이, 본체판(110)과, 복수개의 측면형성용 측판(120)을 구비하는바, 상기 본체판(110)은 제조하고자 하는 콘크리트 패널의 전면과 대응하는 상부면에 일정깊이의 음각부(112)를 함몰형성한 대략 시각판상의 금속판재로 이루어진다. 2 to 4, the mold 100 includes a body plate 110 and a plurality of side plates 120 for forming side surfaces, and the body plate 110 is a concrete panel to be manufactured. It is made of a substantially visual plate-like metal plate formed by recessing the intaglio portion 112 of a predetermined depth on the front surface and the upper surface corresponding to the.
상기 본체판(110)의 외측테두리에는 일정간격을 두고 체결공(114)을 복수개 관통형성하고, 상기 체결공(114)은 상기 측판(120)에 형성되는 체결공(124)과 서로 일치되도록 한다. A plurality of fastening holes 114 are formed through the outer edge of the body plate 110 at predetermined intervals, and the fastening holes 114 are coincident with the fastening holes 124 formed in the side plate 120. .
그리고, 상기 음각부(112)의 바닥면과 상기 측면형성용 측판(120)이 고정설치되는 고정설치면사이에는 도 5와 도 6에 도시한 바와 같이, 제조하고자 하는 콘크리트 패널(200)의 전면(201)과 측면(203)사이에 일정각도로 경사진 모서리면(204)을 형성할 수 있도록 일정각도로 경사진 경사면(113)을 형성한다. In addition, between the bottom surface of the intaglio portion 112 and the fixed installation surface on which the side plate forming side plate 120 is fixed, as shown in FIGS. 5 and 6, the front surface of the concrete panel 200 to be manufactured An inclined surface 113 inclined at a predetermined angle is formed between the 201 and the side surface 203 so as to form an edge surface 204 inclined at a predetermined angle.

상기 캐비티내로 공급되는 콘크리트(C)는 콘크리트 패널의 두께를 얇게 유지하면서 강도발현이 양호하도록 섬유보강재(220)를 혼합하여 사용하는 것이 바람직하다. Concrete (C) supplied into the cavity is preferably used by mixing the fiber reinforcing material 220 to maintain the thickness of the concrete panel while maintaining good thickness.
이러한 섬유보강재(220)는 콘크리트 패널의 기계적 특성을 개선할 수 있도록 사용되는 단섬유상의 보강재를 말하며, 이러한 보강재가 균등히 분산된 콘크리트 패널(섬유보강콘크리트 패널)은 일반 콘크리트 패널에 비해 인장강도, 휨강도가 우수하고, 소성수축, 건조수축 균열을 일반 콘크리트 패널에 비하여 상대적으로 적게 발생시킬 수 있다. The fiber reinforcement 220 refers to a short-fiber reinforcement used to improve the mechanical properties of the concrete panel, the concrete panel (fiber reinforcement concrete panel) in which the reinforcement is evenly distributed compared to the general concrete panel tensile strength, flexural strength It is excellent in plastic shrinkage and dry shrinkage cracking can be generated relatively less than the general concrete panel.
또한, 상기 콘크리트(C)에 포함되는 섬유보강재는 그 굵기가 매우 얇은 섬유의 구조를 가지므로 콘크리트 패널(200)의 두께를 충분히 얇게 하더라도 철근 사용시 발생할 수 있는 녹물발생과 같은 문제가 전혀 유발되지 외장재로 사용될 콘크리트 패널에 가장 적합한 재료라 할 수 있는 것이다.In addition, since the fiber reinforcing material included in the concrete (C) has a very thin fiber structure, even if the thickness of the concrete panel 200 is sufficiently thin, problems such as rust generation that may occur when using reinforcing bars are not caused at all. It is the most suitable material for the concrete panel to be used as.
이러한 섬유보강재로는 탄소강과 스테인리스강을 원료로 한 강섬유, 합성섬유, 유리섬유, 탄소섬유 등을 선택적으로 사용할 수 있으며, PP(Poly-Propylene) 섬유를 적용하는 것이 작업성, 강도, 건조수축에 대한 저항성 등 모든 측면에서 가장 바람직하다. As the fiber reinforcing material, steel fiber, synthetic fiber, glass fiber, carbon fiber, etc., which are made of carbon steel and stainless steel as a raw material, can be optionally used. It is most preferable in all aspects, such as resistance to.
본 발명에 의한 제조방법에서 콘크리트에 포함하여 사용되는 섬유보강재는 얇은 두께의 패널을 제조하는 것을 목적으로 하므로, 섬유보강재인 PP 섬유는 직경 0.1 ~ 2 mm, 길이 4 ~ 6 cm 정도의 실 조각 구조로 가공하여 콘크리트에 혼합하는 것이 바람직하다.In the manufacturing method according to the present invention, the fiber reinforcement used in the concrete is intended to produce a panel with a thin thickness, PP fiber as the fiber reinforcement is 0.1 ~ 2 mm in diameter, 4 ~ 6 cm in length of the thread piece structure It is preferable to process the furnace and mix it with concrete.
이러한 PP 섬유는 직선 형상보다 굽힌 형상으로 형성되는 것이 강도의 발현 측면에서 더욱 바람직하다.It is more preferable that such a PP fiber is formed in a bent shape rather than a straight shape in terms of the development of strength.
이러한 PP 섬유의 혼입량은 콘크리트 1㎥ 당 2 ~ 4 kg 정도가 좋고, 더욱 바람직하게는 콘크리트 1㎥ 당 2.5 ~ 3.5 kg 정도가 가장 적절한 것으로 나타났다.The amount of the PP fiber is preferably about 2 to 4 kg per 1 m 3 of concrete, more preferably about 2.5 to 3.5 kg per 1 m 3 of concrete.
또한, 이러한 섬유보강재(220)를 적용하면서 줄일 수 있는 패널의 두께는 15 ~ 50 cm 정도이고, 더욱 바람직하게는 25 ~ 35 cm인 것으로 나타났다.In addition, the thickness of the panel can be reduced while applying the fiber reinforcement 220 is about 15 ~ 50 cm, more preferably appeared to be 25 ~ 35 cm.
콘크리트 패널(200)을 구성하는 전면(201)의 정교한 마감을 위하여 콘크리트에 포함되는 굵은 골재는 최대치수가 13mm 인 것이 가장 바람직하다.In order to precisely finish the front surface 201 of the concrete panel 200, the coarse aggregate included in the concrete is most preferably having a maximum dimension of 13 mm.
한편, 콘크리트 패널(200)의 강도 및 마감 정도를 우수하게 하기 위해서는 몰드(100)에서 콘크리트를 양생하는 단계에서 상기 몰드(100)에 미세한 진동을 가하는 것이 좋고, 증기양생을 적용하는 경우 더욱 우수한 물성을 가지는 것으로 나타났다.On the other hand, in order to improve the strength and finish degree of the concrete panel 200, it is good to apply a fine vibration to the mold 100 in the step of curing the concrete in the mold 100, more excellent physical properties when applying steam curing It was found to have.
여기서, 상기 몰드(100)에 진동을 제공하는 공정은 고주파와 저주파를 구분하여 각각 30초 동안 일정주기의 진동을 몰드에 인가함으로써 상기 콘크리트가 타설된 본체판 전체를 고르게 진동시킬 수 있고, 이로 인하여 제조되는 콘크리트 패널 제품의 전면을 고르게 형성할 수 있는 것이다. Here, in the process of providing vibration to the mold 100, by separating the high frequency and low frequency and applying a vibration of a predetermined period to the mold for 30 seconds each, the entire body plate on which the concrete is poured can be evenly vibrated, The front surface of the concrete panel product to be manufactured can be formed evenly.
또한, 상기 콘크리트 패널을 양생하는 공정은 짧은 시간의 급결양생은 콘크리트 패널 제품의 표면 질감이 자연스럽지 못하고, 건조한 더운 공기를 이용한 열풍양생은 콘크리트 패널의 분진발생과 강도를 저하시킬 수 있기 때문에 고온의 스팀을 이용한 스팀양생방식으로 콘크리트 패널을 양생하는 것이 바람직하다. In addition, the curing process of the concrete panel is a short time rapid curing of the surface texture of the concrete panel product is not natural, hot air curing using dry hot air can reduce the dust generation and strength of the concrete panel, It is preferable to cure the concrete panel by steam curing method using steam.
그리고, 상기 콘크리트(C)에는 몰드의 캐비티에서 콘크리트 패널 양생시간을 줄일 수 있도록 일정량의 경화제를 포함할 수도 있다. In addition, the concrete (C) may include a certain amount of hardener to reduce the curing time of the concrete panel in the cavity of the mold.
연속하여, 상기 측판분리단계는 상기 본체판(110)에 체결부(125)를 매개로 조립된 측면형성용 측판(120)을 분리하는 것으로, 이는 도 1에 도시한 바와 같이, 상기 체결부(125)의 해체에 의해서 상기 본체판(110)으로부터 자유로워진 패널측면형성 측판(120)을 외측으로 당기어 수평방향으로 분리하면, 상기 본체판(110)의 음각부(112)상에는 콘크리트가 양생되어 경화된 대략 사각판상의 콘크리트 패널(200)은 잔류하고, 상기 콘크리트 패널(200)의 후면 및 측면은 외부로 노출된다. Subsequently, the side plate separation step is to separate the side plate forming side plate 120 assembled through the fastening portion 125 to the body plate 110, which is shown in Figure 1, the fastening portion ( When the panel side forming side plate 120 freed from the main body plate 110 is pulled out by the dismantling of the main body 110 and separated in the horizontal direction, concrete is cured on the intaglio portion 112 of the main body plate 110. The hardened substantially rectangular concrete panel 200 remains, and the rear and side surfaces of the concrete panel 200 are exposed to the outside.
이때, 상기 콘크리트 패널(200)의 측면(203)에는 상기 측면형성용 측판(120)에 구비되는 적어도 하나의 끼움홈 형성용 철물(126)에 의해서 패널시공시 정착구의 상,하부걸림턱이 삽입되는 끼움홈(206)을 형성함과 동시에 상기 끼움홈에는 상기 콘크리트 패널(200)의 후면(202)과 연결되어 상기 정착구가 배치되는 배치홈(206a)을 형성한다.At this time, the upper and lower locking jaw of the fixing unit is inserted into the side surface 203 of the concrete panel 200 by at least one fitting groove forming hardware 126 provided in the side plate forming side plate 120. At the same time to form a fitting groove 206 is connected to the rear surface 202 of the concrete panel 200 to form a placement groove 206a in which the anchorage is disposed.
상기 패널분리단계는 도 1에 도시한 바와 같이, 상기 끼움홈형성용 측판이 분리된 본체판(110)으로부터 양생된 콘크리트 패널(200)을 분리하는 것이다. The panel separating step is to separate the cured concrete panel 200 from the body plate 110, the side plate for forming the fitting groove is separated as shown in FIG.
상기 본체판(110)으로부터 분리된 콘크리트 패널(200)에는 전면(201)과 측면(203)사이 경계영역인 모서리부에 상기 본체판(110)의 음각부에 형성된 경사면에 의해서 모서리면(204)을 형성하고, 전면(201)에는 상기 음각부(112)의 바닥면에 구비되는 복수개의 융기부(115)에 의해서 복수개의 요홈(205)을 함몰형성한다. The concrete panel 200 separated from the main body plate 110 has an edge surface 204 by an inclined surface formed on the intaglio portion of the main body plate 110 at a corner portion that is a boundary area between the front surface 201 and the side surface 203. And a plurality of recesses 205 are recessed on the front surface 201 by a plurality of ridges 115 provided on the bottom surface of the intaglio portion 112.
한편, 상기 본체판으로부터 분리된 콘크리트 패널(200)은 대기 중에서 일정시간동안 자연건조하는 패널건조단계를 수행함으로써 패널에 포함된 수분을 제거하도록 한다. On the other hand, the concrete panel 200 separated from the main body plate to remove the moisture contained in the panel by performing a panel drying step of natural drying for a predetermined time in the air.
이러한 패널건조단계에서 대기중에서 건조되는 콘크리트 패널의 전면(201)은 몰드(100)의 음각부 바닥면에 접촉하여 형성되는 면이므로 매우 매끄럽게 형성되는 반면에 후면(202)은 대기 중에 그대로 노출되어 형성되는바 전면(201)에 비해 거칠게 형성된다.In the panel drying step, the front surface 201 of the concrete panel dried in the air is formed to be in contact with the bottom surface of the intaglio portion of the mold 100, and thus is formed very smoothly, while the rear surface 202 is formed as it is exposed to the atmosphere. Will be formed rougher than the front surface 201.
이때, 거칠게 형성된 콘크리트 패널(200)의 후면(102)은 매끄럽게 형성된 전면(101)에 비해 대기와 노출되는 면적이 크므로 콘크리트 패널 내부에 포함된 수분이 증발하는 양도 상대적으로 전면에 비하여 크기 때문에 상기 콘크리트 패널(200)은 도 10에 도시한 바와 같이, 후면 중앙영역이 상부로 볼록하고 전면 중앙영역이 하부로 오목하도록 휨변형될 수 있다.In this case, since the rear surface 102 of the roughly formed concrete panel 200 has a larger area exposed to the atmosphere than the smoothly formed front surface 101, the amount of moisture contained in the concrete panel is relatively larger than that of the front surface. As shown in FIG. 10, the concrete panel 200 may be flexibly deformed such that the rear center region is convex upward and the front center region is concave downward.
이에 따라, 이러한 콘크리트 패널(200)의 휨변형을 방지하면서 제한된 공간에서 다량의 콘크리트 패널을 건조하기 위해서 도 9와 도 10에 도시한 바와 같이, 전면(201)이 하부로 향하고 후면(202)이 상부로 향하도록 복수개의 콘크리트 패널(200)을 수평하게 다층으로 적층하고, 적층되는 콘크리트 패널(200)들사이에는 패널간격을 유지하도록 복수개의 간격유지부재(230)를 배치한다. Accordingly, in order to dry a large amount of concrete panels in a limited space while preventing bending of the concrete panel 200, as shown in FIGS. 9 and 10, the front surface 201 faces downward and the rear surface 202 is A plurality of concrete panels 200 are horizontally stacked in multiple layers to face upwards, and a plurality of gap maintaining members 230 are disposed to maintain panel gaps between the stacked concrete panels 200.
여기서, 상기 간격유지부재(230)는 상기 콘크리트 패널(200)의 전면에 형성되는 요홈(205)에 상부단이 삽입되어 배치되고 하부단이 인접하는 콘크리트 패널(200)의 후면(204)에 접하도록 배치할 수도 있다. Here, the gap maintaining member 230 is disposed in the groove 205 formed in the front of the concrete panel 200 is inserted into the upper end is in contact with the rear surface 204 of the concrete panel 200 adjacent to the lower end. It can also be arranged to.
이러한 경우, 상기 콘크리트 패널 들사이에는 상기 간격유지부재에 의해서 형성되는 간격을 통하여 자유스럽게 통과하는 공기흐름에 의해서 콘크리트 패널의 전면과 후면에 대한 자연건조가 동일한 조건으로 균일하게 이루어질 수 있다. In this case, natural drying of the front and rear surfaces of the concrete panel may be uniformly performed under the same conditions by the air flow freely passing through the gap formed by the gap maintaining member between the concrete panels.
또한, 수평하게 다층으로 적층되는 콘크리트 패널(200)들은 자중에 의해서 직하부로 인가되는 수직하중(P)에 의해서 패널건조동안 외력을 전달받기 때문에 상부로 휘어지려고 하는 휨변형을 상쇄시켜 콘크리트 패널의 휨변형을 최소화하고, 이로 인하여 편평한 양질의 콘크리트 패널을 제조할 수 있는 것이다.In addition, the concrete panels 200 stacked in a multi-layer horizontally because the external force is transmitted during the drying of the panel by the vertical load (P) applied directly below by its own weight to offset the bending deformation to bend to the top to deflect the concrete panel Minimizing deformation, which makes it possible to produce flat quality concrete panels.
본 발명은 특정한 실시 예에 관련하여 도시하고 설명하였지만, 이하의 특허청구범위에 의해 마련되는 본 발명의 정신이나 분야를 벗어나지 않는 한도 내에서 본 발명이 다양하게 개조 및 변화될 수 있다는 것을 당 업계에서 통상의 지식을 가진 자는 용이하게 알 수 있음을 밝혀두고자 한다.While the invention has been shown and described with respect to particular embodiments, it will be appreciated that the invention can be varied and modified without departing from the spirit or scope of the invention as set forth in the claims below.
