Description

세라믹 침강에 의한 초경량 콘크리트 보호 마감층의 시공방법{A construction method for packing concrete protected layer by ceramic materials} A construction method for packing concrete protected layer by ceramic materials

본 발명은 콘크리트 스라브 상부에 점착증강 프라이머층을 형성하고, 그 위에 합성수지와 세라믹을 이용하여 스라브의 상부 표면을 코팅, 경화시켜 초경량으로 콘크리트 보호 마감층을 시공하는 방법에 관한 것으로, 스라브의 상부 표면에 폴리우레탄계, 에폭시계 또는 FRP계 수지 등의 합성수지와 평균 입경 0.5 ∼ 2.0㎜인 세라믹을 수지 중량에 대하여 30 ∼ 40%의 량으로 혼합한 후, 이 혼합액을 일정 두께로 포설하고 세라믹의 침강원리를 이용하여 세라믹 입자를 침강시킨 후, 다시 그 위에 세라믹을 1 ∼ 2 ㎜ 두께로 2차 침강시켜 울퉁불퉁한 콘크리트의 표면을 면갈기등의 공정을 거치지 않고, 주차장 바닥면, 스라브 지붕면, 수영장 방수면, 놀이시설 바닥면 등의 다양한 콘크리트 구조물에 콘크리트 보호기능과 방수기능 및 미관이 아름다운 효과를 갖도록 하는 콘크리트층 보호 마감층을 형성하는 방법에 관한 것이다.종래의 스라브 지붕 마감공사는 도 1에 도시된 바와 같이 콘크리트스라브(1)의 상부 표면에 방수층(3)을 형성하고, 그 위에 와이어메쉬(4)를 넣은 다음, 누름 콘크리트층(5)을 형성하여 마감층을 시공하게 된다.The present invention relates to a method of forming an adhesive protective primer layer on the upper surface of the concrete slab, and to coat and harden the upper surface of the slab by using a synthetic resin and ceramic thereon to construct a concrete protective finish layer in a super lightweight, the upper surface of the slab To a synthetic resin such as polyurethane, epoxy or FRP resin, and ceramics having an average particle diameter of 0.5 to 2.0 mm in an amount of 30 to 40% by weight of the resin.

이러한 종래의 시공방법은 시간이 경과하면 누름 콘크리트층(5)에 균열이 생겨 방수층(3)을 손상시키므로 누수현상이 일어나고, 계속되는 누수로 인하여 수화현상으로 발생하여 철근의 부식을 유발하게 된다. 이 경우에는 누름 콘크리트층(5)을 모두 철거하고 종래의 공법을 반복하는 경우가 대부분이므로, 마감층의 내구성이 좋지 못하고 반복적인 시공으로 인하여 비용이 많이 발생하며, 마감층의 중량이 많이 나가 건축물 자체에 하중으로 인한 피로도를 증가시키고, 건축물의 손상이 빨리 진행되는 등의 문제점이 있었다.In this conventional construction method, as time passes, cracks are generated in the pressed concrete layer 5, which damages the waterproof layer 3, so that water leakage occurs, and hydration occurs due to continuous water leakage, thereby causing corrosion of the steel. In this case, the pressed concrete layer (5) is all removed and the conventional method is often repeated, so the durability of the finishing layer is poor and the cost is high due to repeated construction, and the weight of the finishing layer is high Increased fatigue due to the load itself, there was a problem such that the damage of the building proceeds quickly.

그러나, 본 발명은 누름 콘크리트와 같이 중량이 많이 나가는 공법을 배제하고, 합성수지를 이용하여 누름 콘크리트와 방수층의 기능을 동시에 부여하는 초경량의 세라믹 수지 마감층을 시공함으로써 콘크리트 보호 마감층을 쉽게 얻을수 있다.However, the present invention can easily obtain a concrete protective finish layer by constructing a super lightweight ceramic resin finish layer that simultaneously imparts the functions of the pressed concrete and the waterproof layer by using a synthetic resin, excluding a heavy weight method such as pressed concrete.

따라서, 본 발명의 목적은 경량이면서도 콘크리트 보호기능과 방수기능을 가지며, 미관이 아름다운 콘크리트 보호 마감층을 시공하는 방법을 제공하는 데 있다.상술한 목적 뿐만 아니라 용이하게 표출되는 다른 목적을 달성하기 위하여 본 발명은 건물 신축시 타설된 콘크리트 스라브 지붕위에 누름 콘크리트를 시공하는 대신 타설된 콘크리트 스라브 구조체의 상부에 세라믹과 합성수지를 배합한 후, 이를 일정 두께로 포설하고, 세라믹 입자가 침강하면 다시 그 위에 한 번 더 세라믹을 일정 두께로 침강시켜 콘크리트 보호기능과 방수기능을 가지며, 미관이 아름다운 콘크리트 보호 마감층을 형성함으로써 주차장 바닥면, 수영장 방수 콘크리트, 놀이시설 바닥면 등 다용도로 활용할 수 있는 공법으로 누구나 간편하게 시공할 수 있을 뿐만 아니라 콘크리트 내부로 CO 2 가스의 침입을 막을 수 있고, 콘크리트의 중성화 방지와 산소, 물의 침투를 방지하여 철근의 부식을 막을 수 있는 효과를 가지게 된다.Accordingly, an object of the present invention is to provide a method for constructing a concrete protective finish layer having a light weight, concrete protection function and waterproof function, and beautiful appearance. In order to achieve the above object as well as other easily expressed objects. According to the present invention, instead of constructing concrete pressed on a concrete slab roof that is poured during construction of a building, the ceramic and synthetic resin are compounded on top of the poured concrete slab structure, and then laid in a predetermined thickness, and when the ceramic particles settle, By setting the ceramic to a certain thickness, it has concrete protection function and waterproof function, and by forming a beautiful concrete protection finishing layer, it can be used for various purposes such as parking lot floor, swimming pool waterproof concrete, and playground floor. As well as construction can be Can be prevented from entering the CO 2 gas into the discrete, by preventing anti-carbonation of the concrete with the oxygen, the water penetration will have the effect to prevent corrosion of the reinforcement.

이하, 첨부 도면에 의해 본 발명의 구성을 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention by the accompanying drawings in detail as follows.

도 2는 본 발명에 의한 초경량 콘크리트 보호 마감층의 스라브 시공방법을 설명하기 위한 단면도이며, 도 3은 본 발명에 의한 스라브 지붕의 부분 단면 상세도로써 상기 도면에서 보면, 콘크리트 스라브(1)의 상부 표면에는 오목부위(8)가 다수 존재한다. 이와 같은 표면을 매끈하게 하기 위해서는 일반적으로 면갈기 등의 공정을 행하고 있으나, 기술적인 면에서나 비용적인 면에서 많은 어려움이 따른다. 본 발명에서는 오목 부위(8)에 세라믹을 침강시켜 고가인 수지의 사용량을 최소화하면서 도막층의 두께를 최대한 높혀줄 수 있게 한다.Figure 2 is a cross-sectional view for explaining the slab construction method of the ultra-lightweight concrete protective finishing layer according to the present invention, Figure 3 is a partial cross-sectional detail view of the slab roof according to the present invention, the upper part of the concrete slab (1) There are many recesses 8 on the surface. In order to smooth such a surface, in general, a process such as surface grinding is performed, but there are many difficulties in terms of technology and cost. In the present invention, it is possible to increase the thickness of the coating layer as much as possible by minimizing the amount of expensive resin by sedimenting the ceramic in the recessed portion (8).

본 발명은 우레탄계, 에폭시계 또는 FRP계 수지에 수지 중량의 30 ∼ 40%의 세라믹을 혼합하여 이를 콘크리트 스라브(1)의 표면에 도 3과 같은 방법으로 포설한다. 포설 순서는 먼저 콘크리트 표면의 먼지를 제거하고, 그 위에 접촉 증강 프라이머(10)를 도포한 후, 일정시간 경과시켜 경화현상이 일어나 프라이머(10)가 충분히 경화된 후, 상기 합성수지와 세라믹의 혼합물을 교반기로 3 - 5분간 충분히 교반한 다음, 고무주걱 등을 사용하여 6 ∼ 10 ㎜ 두께로 골고루 코팅한다.The present invention mixes 30 to 40% of the weight of the resin with a urethane-based, epoxy-based or FRP-based resin and installs it on the surface of the concrete slab 1 in the same manner as in FIG. 3. The installation procedure is to remove the dust on the concrete surface first, and then apply the contact enhancing primer 10 thereon, and after a certain period of time the curing phenomenon occurs, the primer 10 is sufficiently cured, the mixture of the synthetic resin and ceramics After stirring sufficiently for 3-5 minutes with a stirrer, using a rubber spatula, etc., evenly coated to a thickness of 6 ~ 10 mm.

코팅 후 10 ∼ 60분이 경과하여 표면 경화가 일어나면, 그 위에 세라믹을 2차로 1㎡당 2 ∼ 4㎏ 정도 포설하여 코팅 표면층으로 세라믹의 침강이 이루어지도록 한다. 수지와 혼합하여 사용되거나 2차 포설시 사용하는 세라믹의 입자 크기는 입경이 0.5 ∼ 2.0㎜인 것이 바람직하다. 세라믹의 입경이 0.5㎜미만인 경우에는 세라믹의 침강이 잘 이루어지지 않으므로 소기의 목적을 거둘수 없게 되고, 2.0㎜를 초과하는 경우에는 보호 마감층에 균열이 발생하게 되는 결함이 있다.When the surface hardening occurs after 10 to 60 minutes after coating, the ceramic is secondly deposited thereon at about 2 to 4 kg per square meter to allow the ceramic to settle into the coating surface layer. It is preferable that the particle size of the ceramic used in mixing with the resin or used in the secondary installation is 0.5 to 2.0 mm in particle size. If the particle diameter of the ceramic is less than 0.5mm, the sedimentation of the ceramic is not good, so the desired purpose cannot be achieved, and if the diameter exceeds 2.0mm, there is a defect that a crack occurs in the protective finish layer.

본 발명에 의한 콘크리트 보호 마감층은 일반적으로 24 ∼ 48시간 경과 후, 합성수지가 경화되어 보행이 가능하게 되면, 침강되지 않은 잔여 세라믹 입자(7)를 진공청소기로 제거한 후, 시방서의 요구 조건에 따라 지정 색상을 도색함으로써 마감공사를 완료하게 된다.In general, the concrete protective finishing layer according to the present invention, after 24 to 48 hours, when the synthetic resin is cured to allow walking, after removing the remaining non-settled ceramic particles 7 with a vacuum cleaner, according to the requirements of the specification Finishing work is done by painting the designated color.

본 발명은 종래와 달리 누름 콘크리트를 타설 할 필요가 없어, 건물 하중을 크게 줄일 수 있고, 시공비용의 절감을 실현할 수 있을 뿐만 아니라, 노후건물을 수리할 때, 누름 콘크리트층(5)의 제거 없이, 바로 시공이 가능하므로 공사 기간을 단축시킬 수 있고, 폐기물이 거의 발생하지 않게 된다.The present invention does not need to cast pressed concrete unlike the prior art, and can greatly reduce the building load and realize a reduction in construction cost, and also when removing an old building, without removing the pressed concrete layer 5. As construction can be done immediately, construction period can be shortened and waste is hardly generated.

따라서, 본 발명은 신축 또는 개보수 공사시 자원절약 및 공사기간 단축, 하중 최소화 등 공사비 절감에도 크게 기여하는 효과가 있다.Therefore, the present invention has an effect of greatly contributing to the reduction of construction costs, such as resource saving and construction period reduction, load minimization during new construction or renovation construction.
