이때, 상기 기둥헤드(200)는 조립면(230)의 외주면에 단차턱(240)이 형성되어 거푸집 역할의 합성홈을 이루도록 하되, 상기 단차턱(240)의 면상에는 절곡근(241)이 분기되어 현장배근과 결속되도록 형성된다.At this time, the column head 200 has a stepped jaw 240 formed on the outer circumferential surface of the assembly surface 230 to form a composite groove serving as a formwork, but the bent muscle 241 branched on the surface of the stepped jaw 240 It is formed to be bound with the on-site back muscles.

한편, 상기 포스트거더 조립단계(S200)는 상기 기둥헤드의 걸림턱(220)에 포스트거더(300)의 길이방향 단부가 안착되도록 하되, 상기 포스트거더(300)의 길이방향 단부에는 L자형 거더주근(310)이 분기되어 기둥주근(110)과 간섭없이 조립면(230)에 배치된 후 현장콘크리트(500)에 의해 타설시 양생 및 합성되도록 형성된다.On the other hand, the post girder assembly step (S200) is such that the longitudinal end of the post girder 300 is seated on the locking protrusion 220 of the column head, but the L-shaped girder main root at the longitudinal end of the post girder 300 After (310) is branched and disposed on the assembly surface 230 without interference with the column main muscle 110, it is formed to be cured and synthesized during pouring by the on-site concrete 500.

이때, 상기 포스트거더(300)는 길이방향 단부에 L자형 거더주근(310)이 분기되어 기둥주근(110)과 간섭없이 조립면(230)에 배치된 후 현장콘크리트(500)에 의해 타설시 양생 및 합성되도록 형성된다.At this time, in the post girder 300, the L-shaped girder main muscle 310 is branched at the end in the longitudinal direction, and the post girder 300 is placed on the assembly surface 230 without interference with the column main muscle 110, and then cured when pouring by on-site concrete 500. And is formed to be synthesized.

또한, 상기 슬래브 조립단계(S300)는 상기 포스트거더(300)가 조립 완료되면 그 상면에 다수의 피씨슬래브(400)가 안착되도록 형성된다.In addition, the slab assembling step (S300) is formed such that when the post girder 300 is assembled, a plurality of PC slabs 400 are seated on the upper surface thereof.

이는 피씨슬래브의 자중(직하방향 수직 저항력)이 포스트 텐션에 대하여 분산되도록 하기 위함이다.This is to disperse the PC slab's own weight (direct vertical resistance force) against the post tension.

아울러, 상기 현장콘크리트 타설단계(S400)는 상기 피씨슬래브(400)가 조립 완료되면 그 상면에 현장콘크리트(500)를 타설하여 양생한 뒤 일체의 층간을 시공하도록 형성된다.In addition, in the on-site concrete pouring step (S400), when the PC slab 400 is assembled, the on-site concrete 500 is poured on the upper surface of the concrete to be cured, and then an integral interlayer is constructed.

참고로, 본원 발명의 피씨슬래브의 하중은 1/2로 구조해석 한다.For reference, the load of the PC slab of the present invention is analyzed as 1/2.

이때, 기본 모듀율은 8200*8200으로 하는데 이는 기둥 600*600 주차 2500*2대 2600*1대, W=600+5000+2600=8200 이기 때문이다.At this time, the default modulus is 8200*8200 because it is 600*600 parking, 2500*2, 2600*1, W=600+5000+2600=8200.

또한, 피씨기둥(PC COL) 상부에 안착되는 기둥헤드(CH:COL HEAD)는 2400*2400 부재이고, 기둥주근을 통해 기둥헤드를 조립한 뒤 결속근으로 하여금 포스트거더의 인서트 철물을 통해 상호 끼워 넣은 후 무수축 몰탈을 채워서 양생시킨다.In addition, the column head (CH:COL HEAD) seated on the top of the PC COL is a 2400*2400 member, and after assembling the column head through the column reinforcement, the binding bars are interleaved through the insert hardware of the post girder. After adding, fill with non-shrinkable mortar to cure.

그리고, 포스트거더는 단부에 거더주근(압축강선)을 기둥헤드에 앙카시키고 연속 해석으로 조립한다.And, the post girder is assembled by continuous analysis by anchoring the main girder (compressed steel wire) to the column head at the end.

이에, 피씨슬래브는 주근 방향을 기준으로 포스트거더에 80mm 이상 안착시키고 부방향에는 시멘트 페이스트 누출방지용으로 30mm 이상 포스트거더에 걸쳐 놓는것이 바람직하다.Accordingly, it is preferable that the PC slab is seated at least 80mm on the post girder based on the main root direction, and placed over the post girder at least 30mm to prevent cement paste leakage in the negative direction.
