Description

온돌용 마루바닥판재{FLOOR PANEL FOR ONDOL}Floorboard for flooring {FLOOR PANEL FOR ONDOL}
본 발명은 마루바닥판재에 관한 것으로서, 특히, 콘크리트와 무늬목의 장점을 살려, 온돌난방구조에 부적합한 목질계의 마루바닥판재의 단점을 개선함과 아울러 나무판의 자연질감을 그대로 살리도록 하는 온돌용 마루바닥판재에 관한 것이다.The present invention relates to floorboards, in particular, to take advantage of concrete and veneer, to improve the disadvantages of wood floorboards that are unsuitable for ondol heating structure, and to improve the natural texture of woodboards as it is It is about floorboard.
일반적으로 아파트 등의 공동주택에 사용되고 있는 온돌난방의 마루바닥 마감재로서 사용되고 있는 원목 또는 합판, MDF(Medium Density Fiberboard) 등의 목재를 소재로 하는 목질계의 마루바닥판재는, 천연의 나무가 갖는 자연질감으로서 고급스런 실내공간 구성소재로 애용되고 있다.In general, wood-based floorboards made of wood such as wood or plywood and MDF (Medium Density Fiberboard), which are used as flooring finishing materials for ondol heating used in apartment houses, etc. As a texture, it is used as a luxurious interior space material.
도 4는 종래기술인 목질계 마루바닥판재의 시공상태단면도이다.Figure 4 is a cross-sectional view of the construction state of the prior art wood-based floorboards.
도 4에 도시된 바와 같이. 목질계 마루바닥판재(110)는, 콘크리트 타설층(2) 위에 온돌시스템인 난방용 파이프(3)가 배설되고, 이 난방용 파이프(3)를 매설하는 온돌콘크리트층(4) 위에 접착제(120)로 접착 시공된다.As shown in FIG. The wood-based floorboards 110 are provided with an adhesive 120 on the ondol concrete layer 4 which embeds the heating pipe 3 which is an ondol system on the concrete pouring layer 2 and embeds the heating pipe 3. Adhesive construction
이러한 환경 즉, 난방시스템이 공간을 가온시키는 다른 다라들의 난방구조와 달리, 우리나라만의 독특한 바닥판을 직접 가온시키는 온돌난방구조와, 사계절의 기후변화가 판이한 조건에 놓여지는 목질계의 마루바닥판재(110)는 자연재로서의 많은 장점을 가지고 있음에도, 부적절한 문제점을 많이 가지고 있다.Unlike the heating structures of other dallas, where the heating system warms the space, the ondol heating structure that directly warms Korea's unique floorboard, and the wood floor of the four seasons are placed under different conditions. Plate 110 has many advantages as a natural material, but has a lot of inappropriate problems.
그것은 나무의 치명적 약점인 습기 및 온도의 변화에 의한 수축 및 팽창과 이로 인한 길이굽음(Curling), 비틀림 등의 변형과, 누수 또는 침수로 인한 자재의 썩음과 해충에 의한 폐해이다.It is a fatal weakness of trees, which is caused by shrinkage and expansion caused by changes in moisture and temperature, resulting in deformation of curling, torsion, etc., and damage by material rot and pests due to leakage or flooding.
특히 공동주택의 시공에 있어서, 마루바닥판의 하부층인 콘크리트 타설층(2)등의 완전건조가 이루어지는 충분한 시간적 여유를 갖지 못하고, 마루바닥판재가 시공됨으로써, 온돌난방이 가동되면 콘크리트층(2)에 포함되었던 습기가 올라와 목질계의 마루바닥판재(110)를 변형시키게 된다.In particular, in the construction of a multi-family house, it is not possible to have sufficient time for complete drying such as the concrete pouring layer 2, which is the lower floor of the floorboard, and the floorboard is constructed, so that when the heating floor is heated, the concrete floor (2) Moisture included in the rise is to transform the wood floor board 110.
다른 목질계 마루바닥판재의 문제점은, 압축강도가 약함으로서, 찍힘이나 긁힘에 약하여 흠집이 쉽게 발생되고,The problem of other wood-based floorboards is that, due to the weak compressive strength, scratches are easily generated due to weakness of scratches and scratches,
낮은 밀도로 인한 공동주택의 층간 차음기능이 결여되어 소음에 대한 차단기능이 부족하며, 온돌난방의 열전도효율성이 저하되는 문제점이다.Due to the low density, the lack of sound insulation between floors of apartment buildings is insufficient, and the heat conduction efficiency of ondol heating is deteriorated.
뿐만 아니라, 목질계의 마루바닥판재는 내화성이 약하여 화재에 무방비상태이며, 시공 하부층인 콘크리트면에 목재 마루마닥판의 접착시공시 물성이 서로 다른 콘크리트와 목재를 접착하기 위한 접착제로서 에폭시계통을 사용할 수밖에 없어, 인체에 유해한 문제점이 있고, 다른 한편으로는 이러한 에폭시계의 접착제로 접착시공된 마루바닥의 보수작업시에는 접착제가 경화된 후에는 떨어지지 않아 보수면적이 확대되는 어려움이 있다.In addition, the wood floor boards are fireproof due to their low fire resistance, and the epoxy system can be used as an adhesive to bond concrete and wood with different properties when bonding wood floorboards to the concrete surface, which is the lower layer of the construction. Inevitably, there is a problem that is harmful to the human body, and on the other hand, when repairing the floor, which is adhesively bonded with an epoxy-based adhesive, there is a difficulty in expanding the repair area since the adhesive does not fall after curing.
또한 목질계 마루바닥판재는 대부분의 목재를 수입하고 있는 우리나라 여건상 안정적인 원자재 수급에 어려움이 있고 막대한 외화를 낭비하며, 지구촌 자연환경을 훼손하는 문제점이 있었다.In addition, wood floorboard has a problem in that it is difficult to supply stable raw materials, waste a lot of foreign currency, and damage the global natural environment.
본 발명은 상기한 문제점을 해소하기 위하여 안출된 것으로서, 본 발명의 목적은, 습기와 온도, 누수, 침수 등에 의한 변형이 방지되고, 압축강도가 강하여 찍힘 또는 긁힘이 방지되며, 층간 차음기능과 내화성이 강화되고, 온돌의 열전도율을 향상시키며, 인체에 유해한 에폭시계의 접착제를 사용하지 않아도 되고, 유지 및 보수도 용이한 한편, 안정적인 원자재수급이 가능하여 경제적으로 시공할 수 있는 온돌용 마루바닥판재를 제공함에 그 목적이 있다.상기한 목적을 달성하는 본 발명에 따른 온돌용 마루바닥판재는, 측면 길이방향을 따라 서로 대향하는 돌기부와 요홈을 구비하고 옥돌콘크리트층의 상부에 콘크리트 접착제에 의해 부착되는 사각형의 보강시멘트보드와, 상기 보강시멘트보드의 위면에 도포된 방수기능을 구비한 접착제로써 접합되고 표면에 투명보호재가 코팅된 무늬목으로 이루어진 구조로 되어 있다.The present invention has been made in order to solve the above problems, the object of the present invention is to prevent deformation due to moisture and temperature, leakage, immersion, etc., compressive strength is strong to prevent taking or scratching, interlayer sound insulation and fire resistance This reinforced, improved thermal conductivity of ondol, eliminating the use of epoxy-based adhesives that are harmful to the human body, easy maintenance and repair, and stable supply of raw materials makes it possible to economically install on-floor floorboards. It is an object of the present invention to achieve the above-mentioned floorboards for flooring according to the present invention, which has projections and grooves facing each other along the lateral length direction and is attached to the top of the jade concrete layer by a concrete adhesive It is bonded with a rectangular reinforcement cement board and an adhesive having a waterproof function applied to the upper surface of the reinforcement cement board.
