Description
본 발명은 오래된 슬라브 옥상 지붕의 방수 및 단열공사를 비교적 간단한 방법으로 보수하는 옥상 슬라브의 시공방법에 관한 것으로, 보다 상세하게는 콘크리트 옥상 슬라브(1)에 방수층과 단열층을 새로히 형성하는 종래의 시공방법 대신에 아래 쪽에 다수의 홈부(3)를 갖는 단열패널(2)을 앵커볼트(5)에 의해 옥상 슬라브(1)의 상부에 결합 고정시키고, 이 옥상 슬라브(1)의 상면에 접착제를 도포한 후, 그 위에 방수시트(6)를 접합 시공함으로써 단열 및 방수 효과가 우수한 슬라브 지붕의 시공방법에 관한 것이다.The present invention relates to a construction method of a rooftop slab for repairing the waterproofing and insulation work of an old slab rooftop roof in a relatively simple manner, and more specifically, a conventional construction method of newly forming a waterproofing layer and a thermal insulation layer on a concrete rooftop slab (1). Instead, the insulation panel 2 having a plurality of grooves 3 on the lower side is fixed to the upper part of the rooftop slab 1 by the anchor bolts 5, and an adhesive is applied on the upper surface of the rooftop slab 1. After that, by bonding the waterproof sheet 6 thereon, the present invention relates to a method for constructing a slab roof having excellent heat insulation and waterproof effects.
종래에는 슬라브 지붕을 보수할 때, 도 1 에 도시된 바와 같이 먼저 콘크리트 옥상 슬라브(1)위에 방수층(12)을 형성하고, 그 위에 유리섬유(Glass fiber)나 스티로폴을 사용하여 단열층(13)을 형성한 다음, 다시 그 위에 누름 콘크리트층(14)을형성하여 방수성과 단열성을 개선시키는 시공을 하여 왔다.Conventionally, when repairing a slab roof, as shown in FIG. 1, first, a waterproof layer 12 is formed on a concrete rooftop slab 1, and the insulating layer 13 is formed using glass fibers or styropol thereon. After forming, the pressed concrete layer 14 is formed on it, and construction has been performed to improve waterproofness and insulation.
이러한 종래의 방법은 시간이 경과하면 누름 콘크리트층(14)에 균열이 발생하고, 단열층(13) 내부에 빗물이 고이게 되는데, 이와같이 단열층(13)이 물에 젖게되면 단열효과가 크게 저하되며, 겨울철에 결빙하면 그 부피가 팽창하므로 콘크리트층(14)과 방수층(12)이 손상되는 결과를 초래케 된다.In this conventional method, when the time elapses, the crack occurs in the pressed concrete layer 14, and rainwater accumulates inside the heat insulating layer 13. Thus, when the heat insulating layer 13 is wetted with water, the heat insulating effect is greatly reduced, and in winter When the ice is frozen, the volume expands, resulting in damage to the concrete layer 14 and the waterproof layer 12.
이로 인하여 기존의 건축물의 경우, 신축 후 3-4 년이 경과하기 전에 천장에서 누수가 발생하고, 단열효과 저하로 인한 결로현상이 발생하여 천장에 곰팡이가 발생되는등 입주자의 건강을 해칠 염려도 있다..As a result, existing buildings may be leaked from the ceiling 3-4 years after construction and condensation may occur due to the deterioration of insulation effect, causing mold on the ceiling. ..
또한, 이와 같이 균열 및 누수현상이 발생하면, 콘크리트 슬라브(1)의 상부 에 있는 방수층(12), 단열층(13)과 누름 콘크리트층(14)을 모두 제거한 다음, 새로히 동일한 방법에 의한 재시공을 하여야 하는데, 이 때마다 비용이 많이 들고 소음과 먼지, 폐기물등이 많이 발생하므로 많은 피해가 있다.In addition, if cracks and leaks occur in this way, the waterproof layer 12, the heat insulating layer 13, and the pressed concrete layer 14 on the upper part of the concrete slab 1 must be removed, and then reworked in the same manner. This is costly each time there is a lot of noise, dust, waste, etc. There is a lot of damage.
따라서 본 발명은 이상과 같은 종래의 문제점을 해소시키기 위하여 기존의 콘크리트 슬라브 상부에 방수층, 단열층등을 시공하는 대신 하부에 다수의 홈부를 형성한 단열패널을 앵커볼트에 의해 결합.고정시키고, 그 상부에 방수시트를 접합함에 의해서 간편하게 단열, 방수 시공을 할 수 있도록 한다.Therefore, in order to solve the above-mentioned problems, the present invention combines and fixes the insulation panel formed with a plurality of grooves at the bottom by anchor bolts instead of constructing a waterproof layer or a heat insulation layer on the existing concrete slab. By attaching the waterproof sheet to the product, it is possible to easily insulate and waterproof the product.
즉, 콘크리트 슬라브 상면에는 하부에 다수의 홈부가 형성된 단열패널을 결합.고정시켜 상기 홈부에 의하여 단열효과가 발생되도록 하고, 상기 단열패널의 상면에는 접착제로 방수시트를 부착하여 누수가 되지 않도록 한다.That is, the upper surface of the concrete slab is coupled to the insulating panel formed with a plurality of grooves in the lower portion to secure the heat insulation effect by the groove portion, and the waterproof surface is attached to the upper surface of the insulating panel by an adhesive so as not to leak.
따라서, 자주 보수하지 않더라도, 오랜기간 동안 누수되지 않고 우수한 단열효과를 기할 수 있게된다.Therefore, even if not frequently repaired, it is possible to achieve excellent heat insulating effect without leaking for a long time.
