Abstract

The present invention relates to an inverted rib slab for a precast concrete (PC) structure. The inverted rib slab has a supporting rib with a protruding upper part of an inverted tee structure. The slab is formed to easily perform finish construction such as facilities or the like as a ceiling finishing work such as a facility work is easily performed due to a smooth type flat board. Insulation constructing costs are reduced (constructed as a frozen storage). The valid space is expanded due to a flat ceiling. An inter-plate (inter-slab) connecting part ensures the valid depth of tapping concrete (T/C), so the crack generation is markedly reduced. As a discard form (covering plate) is used by being laid on the upper end of the supporting rib, the member weight is markedly reduced due to the inter-supporting rib empty space. Therefore. the stability of a structure is increased, and the danger of a safety accident is markedly reduced during construction. A cross section performance is increased due to the arrangement of a shear reinforcement bar, and the continuity and the integrity of the inter-slab connecting part are excellent. The productivity and the economical efficiency are ensured through the cost reduction due to the cross section reduction.

본 발명은 역 티(Tee) 구조의 상부 돌출형 지지리브를 갖는 피씨형 인버티드 리브 슬래브에 있어서, 상기 슬래브는 민자형 평판으로 인해 천정 마감이 평이하여 설비 등 마감 공사가 용이하도록 형성되고, 단열 공사비가 절감(냉동창고로 시공시)되며, 평평한 천정면으로 하여금 유효공간이 확대됨은 물론 판과 판(슬래브간) 연결부는 탑핑 콘크리트(T/C)의 유효 깊이(Depth)가 크게 확보되어 균열 발생을 현저하게 감소시키고, 버림 거푸집(가림판)을 지지리브 상단에 얹어 사용하도록 함으로써, 지지리브간 빈 공간으로 하여금 부재 자중이 현저하게 감소되어 구조 안전성과 시공중 안전사고 위험이 크게 감소되고, 특히 전단 보강 철근의 배근으로 인해 단면 성능이 증가되는 반면, 슬래브간 접합부의 연속성 및 일체성이 우수하며, 단면 감소로 인한 원가 절감을 통해 생산성과 경제성이 확보되는 것을 특징으로 하는 피씨 구조물용 인버티드 리브(Inver-Teed Rib) 슬래브에 관한 것이다.
The present invention relates to a PC-type inverted rib slab having an upper protruding support rib having a Tee structure, wherein the slab is formed by a flat plate so that the ceiling finish is flat, (T / C) of the connecting portion between the plate and the plate (slab) is secured, and the crack is generated (Blanking plate) is placed on the upper end of the support rib, and the empty space between the support ribs is significantly reduced, so that the structural safety and the risk of safety accidents during installation are greatly reduced. Particularly, The shear reinforcement reinforcement increases the section performance, but the continuity and integrity of the joints between the slabs is excellent, The present invention relates to an inverted-ribbed (Inver-Teed) rib slab for a PC structure.

일반적으로 지하주차장을 포함한 공공시설물 또는 공공주택 등의 건축물을 시공하는 경우에는 많은 하중이 요구되므로, 특허출원 제10-2010-0084034호와 같이 피씨 부재를 제작하여 현장에서 맞춤 조립하도록 형성되고 있으며, 이러한 시공방법은 통상 하프 슬래브(Half PC Slab)를 이용한 PRC(Precast Reinforced Concrete Layer Construction Method) 복합화 공법 등이 실시되고 있다.Generally, when a building such as a public facility or a public house including an underground parking lot is installed, a large load is required. Therefore, a PC member is formed as shown in Patent Application No. 10-2010-0084034, Such a construction method is usually performed by a PRC (Precast Reinforced Concrete Layer Construction Method) composite method using a half slab (Half PC Slab).

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, this PRC composite method is a method of making a PC (Precast Concrete) of reinforced concrete Rahmen structure. It is used to transport PC materials such as PC columns, PC beams, and half slabs And is then formed so as to integrate the structural body by placing overburdened concrete in the field at the junction between the members and the upper part of the half slab.

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.Accordingly, a double-slab method has recently been implemented. That is, the double slab is also referred to as the DTS method. In the double slab, deep reinforcing ribs are provided on the bottom plate, strands are inserted into the lower portion of the reinforcing ribs, and tensile force is applied to the reinforcing ribs. The center portion of the body of the double slab is slightly raised to be raised, and thus it is mainly applied to the ground layer structure with an elongation span of about 10 m 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, in the conventional double-tee slab described above, a plurality of buried connecting roots are usually embedded in the supporting ribs to reinforce the upper portions of the slabs to bend the upper portions of the supporting ribs to form a ceiling portion of the ground or ground floor. The operator must manually insert the PC slab in accordance with the interval set at the time of manufacture, and the troublesome work increases the labor cost and decreases the workability and eventually leads to air delay.

이에, 종래의 피씨 슬래브 종류와 해당 피씨 슬래브의 특장점을 살펴보면 아래 표와 같다.Accordingly, the conventional types of PC slabs and the characteristics of the PC slabs are as follows.

또한, 상기 표 2에서 보는 바와 같이, 종래의 할로코어 슬래브는 두께가 증가하여 층고가 높아지므로 고층건물에 적용시에는 문제가 있으며, 더블티형 하프 슬래브는 현장타설 콘크리트의 물량이 증가하고 리브가 하면에 돌출되어 있어 평면 구성에 제한을 받는다는 문제가 발생되고 있는 실정이다.
As shown in Table 2, the conventional halocarbon slab has a problem in that it is applied to a high-rise building because the thickness of the conventional halocarbon slab is increased to increase the floor height. In the double-tee type half slab, So that there is a problem that the planar configuration is limited.

또한, 상기 표 3에서 보는 바와 같이, 종래의 리브 플러스 슬래브는 구조 강성이 약하고 단열을 위한 내부 스티로폼에 의해 제조 원가가 상승되는 문제가 있으며, 역 리브드 슬래브는 층 두께(리브가 돌출된 높이-일명 리브춤)가 높은 단면에 적용하기 곤란함은 물론 전단보강철근 배근이 불가하여 현장타설 콘크리트와의 합성력이 저하되어 구조 안전성에 문제가 발생하고 있는 실정이다.
In addition, as shown in Table 3, the conventional rib plus slab has a problem that the structural stiffness is weak and the manufacturing cost is increased due to the internal styrofoam for heat insulation. The reverse ribbed slab has a problem that the layer thickness Rib dancing) is difficult to apply to a high section and the shear rebar reinforcement can not be installed. Therefore, the composite strength with the cast concrete is lowered, thereby causing a problem in structural safety.
