Description

지하 구조물의 외단열용 단열방수복합재 및 그 시공 방법{Outside Insulation And Waterproof Member for Underground Structure And Method for Constructing the Same}Insulation and Waterproof Member for Underground Structure And Method for Constructing the Same

본 발명의 건축물의 단열방수복합재 및 그 시공방법에 관한 것으로, 더욱 상세하게는 건축물의 지하부 또는 지하에 건축되는 지하 구조물의 외벽면에 방수시트와 단열재를 일체화하여 시공할 수 있는 지하 구조물의 외단열용 단열방수복합재 및 그 시공 방법에 관한 것이다. The present invention relates to an insulating waterproof composite for a building and a construction method therefor, and more particularly, to an external insulation of an underground structure that can be constructed by integrating a waterproof sheet and an insulating material on the outer wall surface of an underground structure built in the basement or underground of the building It relates to an insulating waterproof composite material for use and its construction method.

지금까지 건축물의 지하부의 외벽면 또는 바닥면 부위를 외단열 및 외방수 시공하기 위해 합리적 수준에서 선정할만한 시공법이 없거나, 해당부위의 하자(누수, 결로 등)가 발생하기 이전까지는 시공의 완성도 확인이 불가능한 부위의 특성 등으로 인해 기술개발 및 발전이 늦어지고 있는 실정이다. Until now, there is no construction method that can be selected at a reasonable level for external insulation and waterproofing construction of the outer wall or floor surface of the basement of the building, or the completion of construction is not confirmed until defects (leakage, condensation, etc.) occur in the relevant part. Technological development and development are being delayed due to the characteristics of impossible areas.

최근 지하부의 하자발생 등으로 인한 유지관리의 중요성을 강조함에 있어서 외단열 및 외방수의 장점이 부각되고 있으나, 기존의 시공방법은 시공의 난이도가 높고 높은 시공 비용으로 인하여 적용성에 한계가 있다. Recently, in emphasizing the importance of maintenance due to the occurrence of defects in the basement, the advantages of external insulation and waterproofing have been highlighted, but the existing construction method has limitations in applicability due to the high difficulty of construction and high construction cost.

또한 기존의 지하부의 외단열 및 외방수 공법은 지하부 골조 공사 후 골조 외부에서 단열 및 방수구조를 설치하기 위한 별도의 작업공간 확보가 요구되어 별도의 터파기 공사가 수반된다. In addition, the existing method of external insulation and waterproofing of the basement requires a separate work space to install the insulation and waterproof structure outside the frame after the construction of the basement, so a separate excavation work is required.

이에 지하부 골조 공사가 마무리 된 후 후속작업이 진행되어야 하는 단열/방수 공정의 간략화를 위해 내단열/내방수로 처리하였으나, 이는 골조가 외부 수분 및 온도에 상시 노출되어 지속적인 하자요인으로 작용하는 문제가 있다. In order to simplify the insulation/waterproofing process, which must be followed up after the construction of the basement frame is completed, it was treated with internal insulation/waterproofing, but this is a problem that the frame is constantly exposed to external moisture and temperature and acts as a continuous defect factor. have.

지하층 외벽면, 특히 지면에 근접하여 매립되는 외벽면(B1층)은 지상의 우수 또는 높은 지하수위에 따른 외부의 수압 발생에 대응하여 반드시 방수층을 설치할 필요가 있으나, 전술한 것과 같이 시공이 편리하고 시공비가 저렴한 내단열/내방수공법을 적용하는 경우에는 외부에서 발생하는 수압에 의해 골조까지 이미 수분이 침투하여 일시적으로는 마감면에 대한 하자가 없는 것으로 보이나, 기간이 경과함에 따라 지속적인 누수 및 결로가 발생할 여지가 있다. The outer wall surface of the basement floor, especially the outer wall surface (B1 floor), which is buried close to the ground, needs to install a waterproof layer in response to the occurrence of external water pressure due to rain on the ground or high ground water level. In the case of applying the low-cost insulation/waterproofing method, moisture has already penetrated to the frame by the external water pressure, so there appears to be no defect on the finished surface temporarily. there is a chance that it will happen

또한 지하층 내부에서 누수 등의 하자 발생시 이미 구조체는 수분이 침투되어 벽체의 건조가 불가능한 상태가 되어 유지보수 자체가 불가능해지는 문제가 있다.In addition, when a defect such as a water leak occurs inside the basement, moisture has already penetrated into the structure, making it impossible to dry the wall, and there is a problem in that maintenance itself becomes impossible.

The waterproof sheet includes a support made of any one of a flat mesh, a nonwoven fabric, a fabric, and a fiber sheet, and a waterproofing material that is applied to the support to cover the support in the form of an adhesive gel.

상기 수용성 이형필름은 폴리비닐알코올(polyvinyl alcohol, PVA) 재질로 된 필름으로 이루어질 수 있다.The water-soluble release film may be made of a polyvinyl alcohol (PVA) material.

상기 본 발명의 외단열용 단열방수복합재를 이용하여 외단열 시스템을 시공하는 방법은, The method of constructing an external insulation system using the insulation waterproof composite for exterior insulation of the present invention is,

를 포함하며, includes,

상기 제4단계에서 타설된 콘크리트의 수분에 의해 상기 수용성 이형필름이 용해되면서 콘크리트와 단열방수복합재의 방수시트가 일체로 접합된다. As the water-soluble release film is dissolved by the moisture of the concrete poured in the fourth step, the concrete and the waterproof sheet of the insulating waterproof composite are integrally bonded.

본 발명에 따르면, 단열재와 방수시트 및 수용성 이형필름이 일체화된 단열방수복합재가 거푸집에 먼저 설치된 후 콘크리트가 타설되면서 방수시트가 콘크리트의 외벽면에 일체로 접합되어 외단열 시스템을 시공할 수 있다. 따라서 외단열 시스템의 시공이 매우 용이하고 경제적으로 이루어질 수 있다.

Hereinafter, with reference to the accompanying drawings, an insulating waterproof composite for external insulation of an underground structure and a construction method thereof will be described in detail according to the embodiments described below. In the drawings, like reference numerals denote like elements.

도 1 내지 도 3을 참조하면, 본 발명의 일 실시예에 따른 지하 구조물의 외단열 시스템은 보호시트(40)-단열재(10)-방수시트(20)-수용성 이형필름(30)이 외측에서 내측으로 순차적으로 적층되어 있는 단열방수복합재(1)를 지하구조물을 이루는 콘크리트(C)의 외벽면에 일체화시킨 구조를 갖는 것으로, 도 2에 도시한 것과 같이 상기 수용성 이형필름(30)은 콘크리트의 수분에 의해 용해되면서 방수시트(20)가 콘크리트(C)의 외벽면에 일체로 접합된다.1 to 3, in the external insulation system of the underground structure according to an embodiment of the present invention, the protective sheet 40-insulation material 10-waterproof sheet 20-water-soluble release film 30 is formed from the outside. It has a structure in which the insulating waterproof composite (1), which is sequentially stacked inside, is integrated with the outer wall surface of the concrete (C) constituting the underground structure, and as shown in FIG. 2, the water-soluble release film 30 is the concrete While being dissolved by moisture, the waterproof sheet 20 is integrally bonded to the outer wall surface of the concrete (C).

상기 단열방수복합재(1)는 지하구조물의 외벽면을 형성하는 콘크리트의 타설을 위한 외측 거푸집(110)과 내측 거푸집(120) 사이에서 외측 거푸집(110)의 내측면에 분리 가능하게 설치된 후, 외측 거푸집(110)과 내측 거푸집(120) 사이로 타설되는 콘크리트(C)에 일체화되면서 콘크리트(C)의 외단열 구조를 이루게 된다. The insulating waterproof composite (1) is detachably installed on the inner surface of the outer formwork (110) between the outer formwork (110) and the inner formwork (120) for pouring concrete forming the outer wall surface of the underground structure. While being integrated with the concrete (C) poured between the formwork (110) and the inner formwork (120), the external insulation structure of the concrete (C) is formed.

상기 단열재(10)는 건축물의 외단열재로 사용하는 공지의 단열재를 적용하여 구성할 수 있다. 상기 단열재(10)의 외측면에는 시공 과정에서 외측 거푸집(110)(도 6 참조)에 의해 단열재(10)가 손상되는 것을 방지하기 위한 보호시트(40)가 부착된다. 상기 보호시트(40)는 시공이 완료된 후 단열재(10)로부터 분리될 수 있으나, 이와 다르게 보호시트(40)를 단열재(10)에서 분리하지 않고 영구적으로 부착하여 사용할 수도 있다.The heat insulating material 10 may be configured by applying a well-known heat insulating material used as an external heat insulating material of a building. A protective sheet 40 is attached to the outer surface of the insulator 10 to prevent the insulator 10 from being damaged by the outer formwork 110 (see FIG. 6 ) during the construction process. The protective sheet 40 may be separated from the insulator 10 after construction is completed, but alternatively, the protective sheet 40 may be permanently attached and used without separating the protective sheet 40 from the insulator 10 .

상기 방수시트(20)는 상기 단열재(10)의 내측면에 접착제 또는 자체 점착력에 의해 부착되며, 우수한 방수성과 내구성 및 부착력을 갖도록 구성된다. 바람직하기로, 상기 방수시트(20)는 편평한 그물망, 부직포, 직물, 섬유시트 중 어느 하나로 된 지지체(21)와, 점착성이 있는 겔(gel) 상으로 되어 상기 지지체(21)에 도포되어 지지체를 덮는 방수재(22)를 포함한다. The waterproof sheet 20 is attached to the inner surface of the heat insulating material 10 by an adhesive or self-adhesive force, and is configured to have excellent waterproofness, durability and adhesion. Preferably, the waterproof sheet 20 has a support 21 made of any one of a flat mesh, non-woven fabric, fabric, and fiber sheet, and is in the form of an adhesive gel and is applied to the support 21 to form the support. and a waterproofing material (22) covering it.

상기 지지체(21)는 상기 방수재(22)가 흘러내리지 않고 시트 형태를 안정적으로 유지하도록 지지하는 작용을 한다. 그리고 상기 방수재(22)는 고형분을 포함하는 겔 상으로 되어 방수성을 제공함과 더불어 콘크리트의 면과 접합될 수 있도록 점착성을 갖는 조성물로 이루어진다.The support 21 serves to support the waterproofing material 22 so as not to flow down and stably maintain the sheet shape. And the waterproofing material 22 is made of a composition having adhesive properties so that it can be bonded to the surface of concrete as well as providing waterproofing in the form of a gel containing solids.

상기 수용성 이형필름(30)은 콘크리트(C) 타설 전에 방수시트(20)를 보호하면서 방수시트(20)가 단열재(10)의 면에 안정적으로 부착된 상태를 유지하도록 하는 작용을 한다. 상기 수용성 이형필름(30)은 거푸집 내측으로 타설되는 콘크리트의 수분에 의해 용해되면서 없어지게 되고, 이로써 방수시트(20)가 콘크리트(C)의 외벽면에 일체로 접합될 수 있다. 상기 수용성 이형필름(30)은 물에 대한 용해성이 높으며 필름 적성이 우수하여 친환경적인 폴리비닐알코올(polyvinyl alcohol, PVA) 재질로 된 필름인 것이 바람직하다. The water-soluble release film 30 serves to keep the waterproof sheet 20 stably attached to the surface of the insulator 10 while protecting the waterproof sheet 20 before the concrete (C) is poured. The water-soluble release film 30 disappears while being dissolved by the moisture of the concrete poured into the mold, whereby the waterproof sheet 20 can be integrally bonded to the outer wall surface of the concrete (C). The water-soluble release film 30 is preferably a film made of an eco-friendly polyvinyl alcohol (PVA) material due to its high solubility in water and excellent film aptitude.
