먼저, 도 1 내지 도 5에 도시된 바와 같이, 본 발명은 벽체 시공단계(S100)와 합성보 조립단계(S200) 및 슬래브 시공단계(S300)로 크게 구성된다.First, as shown in Figures 1 to 5, the present invention is largely composed of a wall construction step (S100) and a composite beam assembly step (S200) and slab construction step (S300).

이에, 상기 벽체 시공단계(S100)는 매립철근(10)에 합성보 접합용 철물 고정구(100)가 장착 결합되도록 하되, 상기 매립철근(10)과 철물 고정구(100)는 복수의 거푸집(20)들이 덧댐 작업이 완료되면 현장 콘크리트에 의해 일체로 양생되어 RC 벽체(W)를 이루도록 형성된다.Thus, the wall construction step (S100) is to be coupled to the steel fixture 100 for joining the composite beam to the buried reinforcing bar 10, the buried reinforcement 10 and the hardware fixture 100 is a plurality of formwork (20) When the padding work is completed, it is integrally cured by on-site concrete to form the RC wall (W).

이때, 상기 철물 고정구(100)는 매립철근(10) 중 수평철근(11)에 대하여 걸침 고정이 가능하도록 결합판(110)이 지지판(120)을 기준으로 꺽임부(130)에 의해 절곡되도록 형성된다.At this time, the hardware fixture 100 is formed so that the coupling plate 110 is bent by the bent portion 130 based on the support plate 120 so that the horizontal reinforcing bar 11 among the reinforcing bars 10 can be fixed. do.

즉, 거푸집을 덧대기 전 매립철근 중 수직철근(12)과 수평철근(11)이 격자 형태로 배근되면 수평철근 중 설계된 위치에 대하여 걸침 형태로 꺽임부가 안착되어 철물 고정구가 안착되도록 형성된다.That is, if the vertical reinforcing bar 12 and the horizontal reinforcing bar 11 among the reinforcing bars are laid in a lattice form before padding the formwork, the bent portion is seated in a cross-shaped form with respect to the designed position of the horizontal reinforcing bar to form a hardware fixture.

이때, 미세 높낮이 조절은 꺽임부와 수평철근 사이에 레벨 조절용 금속 또는 고무패드를 삽입하면서 조정할 수 있도록 형성된다.At this time, the fine height adjustment is formed to be adjusted while inserting a metal or rubber pad for level adjustment between the bent portion and the horizontal rebar.

이때, 상기 결합판(110), 지지판(120) 및 꺽임부(130)는 중앙 지지판넬(140)을 기준으로 측단면 기준 좌우측이 대칭되도록 형성되어 좌우 또는 전후 구분없이 장착 사용시 자유롭도록 형성된다. 이는 공기단축과 작업성이 강화되도록 하기 위함이다.At this time, the coupling plate 110, the support plate 120 and the bent portion 130 are formed so that the left and right sides of the side cross-section are symmetrical with respect to the center support panel 140, and are formed freely when mounted or used without discrimination between right and left. This is to reduce air shortening and workability.

또한, 상기 결합판(110)은 면상에 다수개의 체결공(111)이 형성되어 합성보의 접합판(41)에 형성되 조립공(42)과 대응되면서 볼팅 결합되도록 형성된다.In addition, the coupling plate 110 has a plurality of fastening holes 111 are formed on the surface is formed on the bonding plate 41 of the composite beam is formed to be bolted while corresponding to the assembly hole 42.

At this time, the support plate 120 is such that the support reinforcement 150 is coupled on one side, the support reinforcement 150 is formed so that the pressure bolt 151 penetrates through hole 121 of the support plate.

이에, 상기 가압볼트(151)는 결합판(110)을 향한 단부에 지지블럭(152)이 형성되어 결합판(110)의 배면을 향해 압착되면서 지지력이 보강되도록 형성된다.Thus, the pressure bolt 151 is formed so that the support block 152 is formed at an end toward the coupling plate 110 and is compressed toward the rear surface of the coupling plate 110 to reinforce the supporting force.

이때, 상기 가압볼트(151)는 지지블럭(152)과 대향되는 타측이 홀더블럭(153)의 고정너트(154) 측에 체결되어 나사조임에 의해 전후진되도록 형성된다.At this time, the pressure bolt 151 is formed so that the other side facing the support block 152 is fastened to the fixed nut 154 side of the holder block 153 to be moved forward and backward by screwing.

이에, 상기 홀더블럭(153)은 내부가 빈 박스형 구조로서 각 면상에 콘크리트 유입공(155)이 형성되어 세팅 조절 완료 후 콘크리트가 타설되면 내입된 뒤 일체로 양생되도록 형성된다.Thus, the holder block 153 is an empty box-shaped structure with a concrete inlet hole 155 formed on each surface, and is formed to be integrally cured after being poured after concrete is poured after setting adjustment is completed.

또한, 상기 지지판(120)은 상단부와 하단부에 설정된 길이를 따라 직교 방향으로 길게 연장된 ㄷ-형강(80)이 구비되도록 하되, 상기 ㄷ-형강(80)은 수직철근(12)과 함께 일면이 용접 접합 고정되도록 형성되어 RC 벽체 내에서 철물 고정구(100)가 RC 벽체의 수평방향으로 구조 연속성이 확보되도록 하는 것이 바람직하다. In addition, the support plate 120 is to be provided with a c-beam 80 extending in an orthogonal direction along a length set at the top and bottom, but the c-beam 80 has one side with the vertical rebar 12. It is preferable to form a welding joint so that the hardware fixture 100 in the RC wall ensures structural continuity in the horizontal direction of the RC wall.

한편, 상기 합성보 조립단계(S200)는 상기 벽체 시공단계를 통해 RC 벽체(W)가 완성되면 기초 상면에 설계 위치대로 다수의 피씨기둥(30)들을 세워 장스팬 경간을 이루도록 형성된다.On the other hand, when the RC wall (W) is completed through the wall construction step, the composite beam assembly step (S200) is formed so as to form a long span span by setting a plurality of PC pillars 30 in a design position on the upper surface of the foundation.

이때, 상기 장스팬 경간 사이에는 합성보(40)가 걸침 또는 결합되도록 하되, 상기 합성보(40)는 일측 접합판(41) 단부가 RC 벽체(W)로부터 일부 노출된 철물 고정구(100)의 결합판(110)에 대하여 모멘트 접합(볼팅 조립)되도록 형성된다.At this time, between the span span, so that the composite beam 40 is interposed or coupled, the composite beam 40 is one side of the bonding plate 41, the coupling plate of the iron fixture 100 partially exposed from the RC wall (W) It is formed to be moment-joined (bolted assembly) with respect to (110).

이에, 상기 슬래브 시공단계(S300)는 상기 합성보(40)가 RC 벽체(W)의 철물 고정구(100)에 접합되면서 피씨기둥(30)에 걸침 연결되면 데크플레이트 또는 피씨슬래브(60)를 안착시킨 후 덧침 콘크리트(70)를 타설하여 층간을 시공하도록 형성된다.Thus, in the slab construction step (S300), when the composite beam 40 is joined to the PC pillar 30 while being joined to the hardware fixture 100 of the RC wall W, the deck plate or PC slab 60 is seated. After pouring the concrete 70 is formed to construct the interlayer.

이때, 상기 데크플레이트 또는 피씨슬래브(60)는 합성보에 안착됨에 있어서, 이웃한 데크플레이트 또는 피씨슬래브 대비 주근방향(61)이 직교방향인 격자방향(예컨데 시계방향 또는 반시계 방향으로 돌면서 안착)을 갖도록 형성된다.At this time, since the deck plate or the PC slab 60 is seated on the composite beam, the grid direction in which the main root direction 61 is orthogonal to the neighboring deck plate or the PC slab (eg, seated while turning clockwise or counterclockwise) It is formed to have.

즉, 데크플레이트 또는 피씨슬래브에 분포되는 직하방향 하중이 합성보에 대하여 1/2로 분담하도록 형성되어 피씨거더의 높이(두께)를 줄일 수 있는 바, 이는 제조원가 절감 및 생산성 향상과 함께 경제성이 크게 개선되는 특징이 있다.In other words, the direct load distributed on the deck plate or PC slab is formed to share 1/2 of the composite beam, thereby reducing the height (thickness) of the PC girder, which greatly improves economic efficiency with reduced manufacturing cost and improved productivity. There is a characteristic.
