본 발명은 지하주차장, 지하저류조를 포함한 공공시설물 또는 공공주택 등의 건축물을 시공하기 위한 아이엠티 슬래브(Inverted Multi Tee Slab)에 관한 것으로, 상기 아이엠티 슬래브는 패널의 내부 공간부에 스티로폼(EPS)이 매입된 판형 슬래브로서, 선응력(Prestress)을 도입한 프리캐스트 콘크리트 부재로 인해 처짐 및 균열 방지에 우수하도록 하되, 하부로 돌출된 낮은 단턱은 종전의 리브드 슬래브에 비해 낮은 높이로 돌출되면서 피씨거더에 지지되도록 형성되는 바, 층고가 높아져 유효공간을 확대할 수 있음은 물론 접합 부위의 연속성 및 일체화 성능이 우수하고, 슬래브 자중이 가벼워 전체 건물 중량의 감소로 인한 내진 성능이 유리하며, 바닥 두께 감소로 인한 전체 골조 공사비가 크게 절감되고, 패널 내부에 스티로폼을 매입함으로써 완충 성능이 형성되어 충격흡수 및 단열에 유리한 것을 특징으로 하는 건축물의 장스팬 고하중용 아이엠티 슬래브에 관한 것이다.
The present invention relates to an Inverted Multi Tee Slab for constructing an underground parking lot, a public facility including an underground storage tank, or a public house, wherein the IMT slab has a styrofoam (EPS) in an inner space of a panel. This embedded plate slab is designed to prevent sagging and cracking due to the precast concrete member in which prestress is introduced, and the lower stepped protrusion protrudes to a lower height than the conventional ribbed slab. It is formed to be supported by the girder, which can increase the effective space by increasing the height of the floor, as well as the continuity and integration performance of the joints, and the light weight of the slab, which is advantageous for seismic performance due to the reduction of the overall weight of the building. Significant reduction in overall frame construction cost due to the reduction, and cushioning performance by molding styrofoam inside the panel The present invention relates to a long span heavy load IMT slab of a building, characterized in that it is advantageous for shock absorption and insulation.

일반적으로 지하주차장을 포함한 공공시설물 또는 공공주택 등의 건축물을 시공하는 경우에는 많은 하중이 요구되므로, 하프 슬래브(Half PC Slab)를 이용한 PRC(Precast Reinforced Concrete Layer Construction Method) 복합화 공법 등이 실시되고 있다.In general, when constructing public facilities including underground parking lots or buildings such as public housings, a lot of loads are required, and thus, a PRC (Precast Reinforced Concrete Layer Construction Method) complex method using half PC slab is implemented. .

즉, 이러한 PRC 복합화 공법은 철근 콘크리트 라멘(Rahmen) 구조의 건물을 PC(Precast Concrete)화하는 공법으로서, 공장에서 제작한 PC기둥, PC보, 하프 슬래브 등 PC부재를 현장으로 운송, 양중하여 조립한 후 부재 간 접합부와 하프 슬래브의 상부에 덧침 콘크리트를 현장에서 타설하여 구조체를 일체화시키도록 형성된다.In other words, the PRC compounding method is a method of converting a reinforced concrete ramen (PC) structure into a PC (precast concrete). It is then formed to cast the concrete on the site of the joint between the members and the top of the half slab in the field to integrate the structure.

이에, 최근에는 더블티 슬래브공법이 실시되고 있다. 즉, DTS 공법이라고도 하는데 더블티 슬래브는 바닥판에 깊은 보강리브를 설치하고 상기 보강리브의 하부에 스트랜드를 삽입하여 인장력을 가한 뒤 일체의 부재를 이루도록 형성하는 바, 이러한 더블티 슬래브는 스트랜드의 인장력으로 인해 더블티 슬래브의 몸판 중앙부가 소폭 치켜 올려지도록 형성되어 약 10m 이상의 장스팬으로 지상층 구조물에 주로 적용되고 있다.In recent years, the double tee slab method has been implemented. In other words, it is also called DTS method. Double tee slab is formed to install a deep reinforcing rib on the bottom plate, insert a strand in the lower part of the reinforcing rib, and apply a tensile force to form an integral member. Due to this, the central part of the body plate of the double tee slab is raised slightly and is mainly applied to the ground layer structure with a long span of about 10m or more.

그러나, 상술한 종래의 더블티 슬래브는 통상 보강을 위해 지지리브 내에 다수개의 매립 연결근을 심어 상부를 절곡시킨 후 덧침 콘크리트에 의해 지하층 또는 지상층의 천정부를 형성하도록 하고 있으나, 이러한 매립 연결근은 공장에서 피씨 슬래브를 제작시 작업자가 수작업으로 일일이 설정된 간격에 맞춰 끼워 넣어야 하는 바, 번거로운 작업에 의해 인건비의 상승과 작업성의 저하 결국 공기 지연으로 연결되는 문제가 발생되고 있다.However, the above-described conventional double tee slab is usually bent in the upper part by planting a plurality of buried connection roots in the support ribs for reinforcement to form a ceiling of the basement or ground layer by the overlay concrete, but such a buried connection root is factory In manufacturing the PC slab, the worker has to manually insert the bar at a set interval by hand, which leads to an increase in labor costs and lower workability due to cumbersome work, which leads to air delay.

또한, 종래의 더블티 슬래브는 단열이나 충격에 대한 완충 역활을 하는 구조가 전무한 실정이고, 이러한 종래의 트러스근 보강형 하프 슬래브의 바닥판은 트러스근의 제작설비가 별도로 필요하며, 상부 배근작업이 평판에 비해 불편함은 물론 양중시 균열 문제가 발생되고 있는 실정이다.In addition, the conventional double tee slab has no structure to act as a buffer against the heat insulation or impact, and the bottom plate of the conventional truss reinforcement type half slab requires a separate truss manufacturing equipment, and the upper reinforcement work Inconvenience as compared to the plate as well as the situation in which the cracking problem occurs.

또한, 종래의 속빈형 하프 슬래브의 바닥판은 두께가 증가하여 층고가 높아지므로 고층건물에 적용시에는 문제가 있으며, 더블티형 하프 슬래브의 바닥판은 현장타설 콘크리트의 물량이 증가하고 리브가 하면에 돌출되어 있어 평면구성에 제한을 받는다는 문제가 발생되고 있는 실정이다.
In addition, the bottom plate of the conventional hollow half slab has a problem that it is applied to a high-rise building because the thickness of the bottom plate is increased to increase the thickness, the bottom plate of the double-tee type half slab increases the amount of cast-in-place concrete and protrudes on the bottom surface of the rib There is a problem that the planar configuration is limited.

본 발명은 상술한 문제점을 해결하기 위한 것으로, 그 기술적 요지는 지하주차장, 지하저류조를 포함한 공공시설물 또는 공공주택 등의 건축물을 시공하기 위한 아이엠티 슬래브(Inverted Multi Tee Slab)에 관한 것으로, 상기 아이엠티 슬래브는 패널의 내부 공간부에 스티로폼(EPS)이 매입된 판형 슬래브로서, 선응력(Prestress)을 도입한 프리캐스트 콘크리트 부재로 인해 처짐 및 균열 방지에 우수하도록 하되, 하부로 돌출된 낮은 단턱은 종전의 리브드 슬래브에 비해 낮은 높이로 돌출되면서 피씨거더에 지지되도록 형성되는 바, 층고가 높아져 유효공간을 확대할 수 있음은 물론 접합 부위의 연속성 및 일체화 성능이 우수하고, 슬래브 자중이 가벼워 전체 건물 중량의 감소로 인한 내진 성능이 유리하며, 바닥 두께 감소로 인한 전체 골조 공사비가 크게 절감되고, 패널 내부에 스티로폼을 매입함으로써 완충 성능이 형성되어 충격흡수 및 단열에 유리한 것을 특징으로 하는 건축물의 장스팬 고하중용 아이엠티 슬래브를 제공함에 그 목적이 있다.

본 발명은 도 1 내지 도 7에 도시된 바와 같이, 장스팬 패널(100)의 내부에 길이방향으로 관통된 공간부(110)가 형성되되, 상기 공간부에는 스티로폼(200:EPS)이 삽입되도록 형성된다.1 to 7, the space portion 110 penetrated in the longitudinal direction is formed inside the long span panel 100, so that the styrofoam 200 is inserted into the space portion. Is formed.

이때, 상기 공간부는 중앙 격벽(120)에 의해 분리되며, 상기 패널(100)의 하부에는 하향 돌출된 다수개의 단턱(130)이 형성된다.In this case, the space portion is separated by the central partition wall 120, a plurality of stepped protrusion 130 is formed in the lower portion of the panel 100 protruding downward.

이에, 상기 단턱(130)에는 철근(140)이 매립되어 일부가 상향 분기되도록 형성되고, 상기 패널(100)의 좌우 폭방향 양단에는 패널의 하부 두께층(150)으로부터 연장된 걸침리브(160)가 형성되어 이루어진다.Thus, the reinforcement 140 is embedded in the stepped portion 130 so that a part thereof is branched upward, and the interlocking rib 160 extending from the lower thickness layer 150 of the panel is formed at both ends in the left and right width directions of the panel 100. Is formed.

이러한 아이엠티 슬래브는 하부 단턱이 피씨거더의 내측벽과 맞닿아 대응되면서 견고한 전단 저항력을 갖도록 형성되면서 높은 층고를 확보할 수 있도록 형성된다.The IMT slab is formed to secure a high floor height while being formed to have a strong shear resistance while the lower step is in contact with the inner wall of the PC girder.

이때, 상기 철근은 이웃한 패널의 철근과 연결근에 의해 조임되면서 폭방향 구조 연속성을 확보하도록 형성된다.In this case, the reinforcing bar is tightened by the reinforcing bar and the connecting bar of the adjacent panel is formed to ensure the structural continuity in the width direction.

이때, 상기 걸침리브는 이웃한 걸침리브와 대응시 일종의 홈을 형성하여 현장 타설 콘크리트의 양생 존(ZONE)을 형성하여 구조 일체성을 확보하도록 형성된다.At this time, the latching ribs are formed to form a kind of grooves in correspondence with neighboring latching ribs to form a curing zone (ZONE) of the cast-in-place concrete to secure structural integrity.

이에, 상기 패널(100)은 층고를 현저히 낮출 수 있도록 길이방향 단부측에 해당하는 두께층(150)과 걸침리브(160)가 일부 절개되어 안착턱(180)이 형성되는 것이 바람직하다.Thus, the panel 100 preferably has a mounting layer 180 formed by partially cutting the thickness layer 150 and the latching rib 160 corresponding to the longitudinal end side in order to significantly lower the height of the floor.

즉, 상기 안착턱은 걸침턱보다 더 낮은 상태로 아이엠티 슬래브가 피씨거더에 안착결합될 수 있도록 형성된다.
That is, the seating jaw is formed to be seated coupled to the PC girder in a lower state than the stepped jaw.
