상기와 같이 거더(10)의 원하는 부분에만 프리스트레스가 도입되도록 하기 위하여 에폭시와 같은 응고시간지연접착수지재를 강선 또는 강봉의 표면에 일정한 두께로 도포표면이 거칠게 일정범위에 걸쳐 도포하는 이유는 상기 거더(10)의 상하면의 일정길이에 걸쳐 프리스트레스가 도입되지 않도록 하기 위하여 상기 강선 또는 강봉(11)의 일정범위에 걸쳐 응고시간지연접착수지재를 도포한 다음, 상기 접착수지재가 경화되기 전에 강선 또는 강봉(11)을 긴장한 상태에서, 강선 또는 강봉(11)을 포함하는 콘크리트를 타설경화시키고, 강선 또는 강봉을 강선체결공(72)으로부터 이탈시켜 릴리스하면, 응고시간지연접착수지재가 도포된 강선 또는 강봉에는 상기 접착수지재가 경화되지 않고 겔상태로 있어 콘크리트가 접착되지 않아 강선 또는 강봉에 도입된 프리스트레스가 거더에 도입되지 않는 반면에, 상기 응고시간지연접착수지재가 도포되지 않은 강선 또는 강봉(11)은 콘크리트와 접착되어 강선 또는 강봉에 도입된 프리스트레스가 거더(10)의 콘크리트에 전달되어 프리스 트레스가 도입되도록 한 것이다.The reason for applying the coagulation time delay adhesive resin such as epoxy to the surface of the steel wire or the steel rod at a constant thickness to a predetermined thickness to ensure that the prestress is introduced only to the desired portion of the girder 10 is as described above. In order to prevent the prestress from being introduced over a predetermined length of the upper and lower surfaces of (10), the solidification time delay adhesive resin material is coated over a certain range of the steel wire or steel bar 11, and then the steel wire or steel bar is before the adhesive resin material is cured. When the steel (11) is tense, the steel including the steel wire or steel bar (11) is pour-hardened, and the steel wire or steel bar is released from the steel fastening hole 72 and released, the steel wire or steel bar coated with the solidification time delay adhesive resin material The adhesive resin material is not cured and is in a gel state so that the concrete is not bonded to the steel wire or the steel bar. While the wristless is not introduced to the girder, the steel wire or steel rod 11, to which the solidification time delay adhesive resin material is not applied, is bonded to the concrete and the prestress introduced to the steel wire or steel rod is transferred to the concrete of the girder 10 to freeze. The tress was introduced.

한편, 상기 강선 또는 강봉(11)에 도포된 응고시간지연접착수지재의 경화시간을 24 ~ 36시간이 경과된 후에 경화가 진행되도록 한 것이므로, 콘크리트가 타설되어 경화되고, 콘크리트에 프리스트레스가 도입된 후에, 강선 또는 강봉에 도포된 응고시간지연접착수지재가 경화되어 콘크리트와 일체화되어 프리스트레스가 도입되지 않도록 한 것이며, 강선 또는 강봉에 도포된 표면을 거칠게 일정두께로 한 것은 상기 일정시간 경과되어 접착수지재가 경화되어 콘크리트와 일체화될때 표면의 거친면에 의하여 접착력이 강화되어 일체거동하도록 한 것이다.On the other hand, since the curing time of the coagulation time delay adhesive resin material applied to the steel wire or steel bar 11 to 24 to 36 hours has elapsed, the curing proceeds, after the concrete is poured and cured, prestress is introduced into the concrete , The coagulation time delay adhesive resin applied to the steel wire or steel rod is hardened so that it is integrated with concrete so that prestress is not introduced, and the surface coated on the steel wire or steel rod is roughened to a certain thickness so that the adhesive resin hardens after the predetermined time. When it is integrated with concrete, the adhesive force is strengthened by the rough surface of the surface so as to be integrated.

상기 강선 또는 강봉(11)을 릴리스하여 응고시간지연접착수지재가 경화되기 전에 겔상태로 일정한 시간(24 ~ 36시간)동안 있도록 하여 강선 또는 강봉을 릴리스하여 강선 또는 강봉이 줄어들때에도 상기 강선 또는 강봉외부에 도포된 겔상태에 응력이 전달되지 않도록 하기 위함인 것이다. Release the steel wire or rod 11 so that the coagulation time delay adhesive resin material is hardened for a certain time (24 to 36 hours) in a gel state so that the steel wire or steel bar is released by releasing the steel wire or steel bar to reduce the steel wire or steel bar This is to prevent stress from being transferred to the gel state applied to the gel.

결국, 시간차에 의하여 프리스트레스를 원하는 부분인 정모멘트가 작용하는 거더의 상하면에 선택적으로 프리스트레스가 도입되도록 하면서 그 외의 부분에도 접착수지재가 일정시간이 경과된 후에 경화되어 콘크리트와 접착되어 일체거동하도록 한 것이다.As a result, the prestress is selectively introduced into the upper and lower surfaces of the girder where the positive moment acts as the desired part of the prestress due to the time difference, and the adhesive resin material is also hardened after a certain time has elapsed and bonded to the concrete to act integrally. .

상기 응고시간지연접착수지재인 에폭시등이 도포된 도포부(21)는, 상부단면에 설치된 강선 또는 강봉의 경우, 거더길이(L)의 0.75L ~ 0.9L이며, 하부단면에 설치된 강선 또는 강봉의 경우, 거더길이(L)의 0.1L ~ 0.25L의 범위에 걸쳐 설치한 것이며, 상기 도포부(21)의 범위는 프리스트레스미도입부(25)의 범위와 같다.The coating part 21 coated with epoxy, which is the solidification time delay adhesive resin, is 0.75L to 0.9L of the girder length L in the case of the steel wire or the steel bar installed on the upper end surface, and the steel wire or the steel bar installed on the lower end surface. In this case, it is provided over the range of 0.1L-0.25L of girder length L, and the range of the said coating part 21 is the same as the range of the prestress non-introduction part 25. As shown in FIG.

상기와 같이 응고시간지연접착수지재를 도포하여 프리스트레스를 도입하지 않은 부분을 거더(10)의 상하부에 선택적으로 설치한 것은 향후에 설명되는 본 발명의 슬래브구조체(80) 시공시 빔(81)위에 거치된 프리스트레스트콘크리트합성거더(10)를 거치하면서 상기 거더(10)의 양단에 노출된 노출강선(12)에 정착클립을 설치하고, 콘크리트를 타설경화시켜 슬래브를 설치하면서 상기 노출강선에 설치된 정착클립이 콘크리트에 매입되도록 한 연결부를 설치하여 콘크리트의 슬래브와 거더가 일체연결되어 일체거동할 때,As described above, the portion of the slab structure 80 of the present invention which will be described later will be selectively installed on the upper and lower portions of the girder 10 by applying the solidification time delay adhesive resin material. Fixing clips are installed in the exposed steel wire 12 exposed to both ends of the girder 10 while the mounted prestressed concrete composite girder 10 is installed, and the slab is installed by hardening concrete to install the slab. When the slab and the girder of the concrete are integrally connected to each other by installing the connection part so that the clip is embedded in the concrete,

상기 거더에 작용하는 하중에 의하여 거더에 교차적으로 정부모멘트가 발생되어, 상기 작용하는 부모멘트가 거더에는 압축력으로 작용하게되므로, 상기 거더의 상하부만에 선택적으로 설치된 프리스트레스미도입부(25)에 상기 발생된 압축력이 전달되면, 상기 거더(10)의 프리스트레스미도입부에 의하여 발생된 압축력이 감소되도록 한 것이다.The moment is generated in the girders cross-over by the load acting on the girders, the acting parent moment acts as a compressive force to the girders, so that the prestress unintroduced portion 25 selectively installed only on the upper and lower portions of the girders When the generated compressive force is transmitted, the compressive force generated by the prestress unintroduced portion of the girder 10 is reduced.

결국, 일반적인 거더에 발생되는 압축력의 크기보다 획기적으로 크기를 감소시켜 슬래브 자체 또는 연결부의 파괴등을 방지하여 슬래브구조체의 안정성이 보다 크게 확보될 수 있도록 한 것으로서 도 14의 도시된 것과 같이 모멘트가 발생된 부분에 프리스트레스미도입부를 설치한 것이다. As a result, the moment is generated as shown in FIG. 14 as the stability of the slab structure is more secured by significantly reducing the size of the compressive force generated in the general girder to prevent destruction of the slab itself or the connection part. The prestressed non-introduction part is installed in the part which was made.

상기 방법에 의하여 제작된 거더는 상하부에 일정한 간격을 두고 골고루 설치된 다수개의 강선 또는 강봉에 의하여 선택적으로 상하면에 프리스트레스가 도입된 상태이므로 거더의 전단면이 유효한 단면인 반면에,Whereas the girder produced by the above method is a state in which the prestress is selectively introduced on the upper and lower surfaces by a plurality of steel wires or rods evenly spaced at regular intervals on the upper and lower sides, while the shear surface of the girder is an effective cross section,

기존의 콘크리트거더는 상부의 압축부만 유효한 단면이 되므로, 활용성면에 서 기존 거더의 활용범위 보다, 본 발명 거더의 활용범위를 보다 광범위하게 사용할 수 있으며, 거더의 두께를 줄일 수 있는 장점이 있다.Existing concrete girders are effective cross section only the upper compression section, in terms of usability can be used more widely than the range of the existing girder, the scope of use of the girder of the present invention, there is an advantage to reduce the thickness of the girder .

또한, 상기 거더의 상하면에 선택적으로 설치된 프리스트레스미도입부(25)와 노출강선(12)에 설치된 정착클립(83)에 의하여 슬래브 콘크리트가 일체화된 연결부(90)에서 발생되는 모멘트를 감소시켜 연결부(90)가 파괴되는 것을 방지하므로서 슬래브구조체(80)의 내하력을 증강시키도록 한 것이다.In addition, the connection portion 90 by reducing the moment generated from the connection portion 90 is integrated with the slab concrete by the pre-stress non-introduction portion 25 and the fixing clip 83 installed on the exposed steel wire 12 selectively installed on the upper and lower surfaces of the girder. ) To increase the load capacity of the slab structure (80) while preventing destruction.

상기 거더제작대(30)의 각각의 구성을 도면에 의하여 설명하면 다음과 같다.Referring to the drawings, each configuration of the girder production stage 30 is as follows.

상기 지지대(40)는 철근콘크리트로 수직지지부(41)와 수평지지부(42)의 ㄴ자형으로 설치하되, 수평지지부(42)를 지반(31)내에 매입설치하되, 상기 수평지지부(42)가 내측으로 설치되도록 한 것이 도 5(a)이다.The support 40 is installed in the shape of the vertical support portion 41 and the horizontal support portion 42 of the reinforced concrete, the horizontal support portion 42 is embedded in the ground 31, the horizontal support portion 42 is installed inside Figure 5 (a) is to be installed.

상기 수평지지부(42)를 내측으로 일정길이로 설치하면, 수평지지부(42)의 측면에서 유압잭(34)에 의하여 발생되는 스트로크에 의하여 수직지지부(41)가 내측으로 전도되려는 힘을 상기 스트로크힘의 작용방향과 반대방향으로 일정길이 설치되는 수평지지부(42)의 지지력에 의한 힘보다 작게 하여 지지대(40)가 안전하게 지지되어 거더(10)를 제작할 수 있도록 한 것이다.When the horizontal support portion 42 is installed to a predetermined length inwardly, the force that the vertical support portion 41 is to be transferred inwards by the stroke generated by the hydraulic jack 34 on the side of the horizontal support portion 42 is applied to the inner side of the stroke force. The support 40 is safely supported by a force less than the force of the horizontal support portion 42 which is installed at a predetermined length in the direction opposite to the action direction so that the girder 10 can be manufactured.

상기 수직지지부(41)에는 다수개의 관통공(43)이 형성되고, 상기 관통공(43)내에는 관(44)을 삽입한 것이다.A plurality of through holes 43 are formed in the vertical support part 41, and the tube 44 is inserted into the through holes 43.

상기 관통공(43)내에 관(44)을 삽입한 이유는 관(44)내에 향후에 설치되는 강봉(32)이 유압잭(34)에 의하여 관(44)내에서 이동할 때 관통공(43)내에서 원활하게 이동할 수 있도록 안내관의 역할을 하도록 하기 위함이다. The reason why the pipe 44 is inserted into the through hole 43 is that the steel bar 32 which is installed in the pipe 44 in the future is moved in the pipe 44 by the hydraulic jack 34. To act as a guide to move smoothly in the.

도 5(b)는 수직지지부(41)의 내외면에 도 5의 단부지압강판(50)이 매입된 상태를 보여주는 것이다.FIG. 5 (b) shows a state in which the end pressure bearing steel plate 50 of FIG. 5 is embedded in the inner and outer surfaces of the vertical support part 41.

상기 단부지압강판(50)은 직각사각형의 강판으로 다수개의 관통공(51)이 형성된 것이다.The end pressure-bearing steel sheet 50 is a rectangular steel sheet formed with a plurality of through holes 51.

상기 관통공(51)은 수직지지부(41)의 관통구(43)에 일치되게 설치되는 것이다.The through hole 51 is installed to coincide with the through hole 43 of the vertical support part 41.

상기와 같이 단부지압강판(50)의 관통공(51)과 수직지지부(41)의 관통공(43)을 일치시켜 설치하고, 양단부에 나사산(33)이 형성된 강봉(32)을 관통설치한다.As described above, the through hole 51 of the end pressure-bearing steel plate 50 and the through hole 43 of the vertical support part 41 are coincident with each other, and the steel rods 32 formed with the thread 33 are provided at both ends.

상기 단부지압강판(50)을 수직지지부(41)의 내외면에 매입설치하는 이유는 유압잭의 스트로크에 의하여 강선 또는 강봉(11)에 긴장력이 도입될때 수직지지부(41)의 단면을 보강하기 위하여 설치하는 것이다. The reason why the end pressure-bearing steel plate 50 is installed on the inner and outer surfaces of the vertical support part 41 is to reinforce the cross section of the vertical support part 41 when a tension force is introduced into the steel wire or the steel bar 11 by the stroke of the hydraulic jack. It is.

또한, 수직지지부(41)의 외측에서 일정거리 떨어져 설치되는 것으로서, 도 7의 직사각형의 강판으로 다수개의 관통공(61)이 설치된 가동지압강판(60)이다. In addition, it is provided a predetermined distance away from the outside of the vertical support portion 41, the movable steel plate 60 is provided with a plurality of through-holes 61 of the rectangular steel sheet of FIG.

상기 관통공(61)은 상기 단부지압강판(50)의 관통공(51)과 수직지지부(41)의 관통공(43)이 하나의 강봉(32)으로 상호 관통 체결되도록 하기 위한 것이다.The through hole 61 is for allowing the through hole 51 of the end pressure-bearing steel plate 50 and the through hole 43 of the vertical support part 41 to be penetrated through each other by one steel bar 32.

상기 가동지압강판(60)은 향후 유압잭(34)에 의하여 뒤쪽으로 이동하여야 하므로 유압잭의 스트로크 힘을 전부 받아야 하므로 강판의 강성이 높아야 한다.Since the movable acupressure steel sheet 60 should be moved backward by the hydraulic jack 34 in the future, the hydraulic jack should receive all of the stroke force, so the rigidity of the steel sheet should be high.

도 8(a)의 강선체결지압강판(70)은 수직지지부(41)의 내측에서 일정거리 간격을 두고 설치되는 것으로서, 직사각형의 강판에 다수개의 관통공(71)과 강선체결공(72)이 동시에 형성된 것이다.The steel fastening bearing steel sheet 70 of FIG. 8 (a) is installed at a predetermined distance from the inside of the vertical support portion 41, and a plurality of through holes 71 and the steel wire fastening holes 72 are formed in a rectangular steel sheet. It is formed at the same time.

상기 관통공(71)은 수직지지부(41)의 관통공(43)과 상기 수직지지부의 내외면에 매입된 단부지압강판(50)의 관통공(51)과 가동지압강판(60)의 관통공(61)을 모두 관통하여 강봉을 설치하기 위한 것이다.The through hole 71 is a through hole 43 of the vertical support part 41 and a through hole 51 of the end pressure bearing steel plate 50 embedded in the inner and outer surfaces of the vertical support part, and a through hole of the movable pressure steel plate 60. It is for installing a steel bar through all 61.

상기 강봉(32)이 관통공(61,71)에 삽입된 상기 가동지압강판(60)과 강선체결지압강판(70)과 강봉(32)을 너트(36)에 의하여 각각 체결고정한다. The steel bar 32 is fastened and fastened to the movable acupressure steel plate 60, the steel wire fastening pressure steel plate 70, and the steel bar 32 inserted into the through holes 61 and 71 by nuts 36.

상기와 같이 관통공(61,71)에 삽입된 각각의 강판(60,70)을 너트(36)로 고정체결하여야 유압잭(34)에 의하여 가동지압강판(60)이 외측으로 밀리면 강선체결지압강판(70)도 동시에 상기 가동지압강판이 이동한 동일한 양만큼 이동하도록 하기 위함이다. As described above, each steel plate 60 and 70 inserted into the through holes 61 and 71 must be fastened by a nut 36. When the movable pressure steel plate 60 is pushed outward by the hydraulic jack 34, the steel wire fastening pressure plate At the same time as 70, the movable acupressure steel sheet is moved by the same amount moved.

도 8(b)는 상기 강선체결공(72)을 상세히 보여주면서 동시에 강선 또는 강봉(11)의 단부가 체결고정된 것을 보여주는 도면이다.8 (b) shows the wire fastening hole 72 in detail and at the same time shows that the end of the steel wire or steel rod 11 is fastened and fastened.

상기 강선체결공(72)은 열쇠구멍의 형상으로, 상부는 원형구멍(73)이 형성되고 이와 접하여 하부에는 상기 원형구멍(73)보다 폭은 작으나 길이는 길게 형성된 수직구멍(74)이 형성된 것이다. The steel wire fastening hole 72 is in the shape of a key hole, the upper portion is formed with a circular hole 73 is in contact with the lower portion is formed with a vertical hole 74 formed in a smaller width than the circular hole 73 but longer in length. .

상기와 같이 형성된 강선체결구멍(72)에 도 8(c)와 같이 강선 또는 강봉(11)의 단부를 강선 또는 강봉의 직경보다 크게 설치한 확대두부(24)를 상기 원형구멍(73)내에 밀어넣은 다음, 상기 원형구멍(73)의 하부에 연접하여 설치된 수직구멍(74)으로 밀어내리면 도 8(b)와 같이 수직구멍(74)에 강선 또는 강봉의 확대두부(24)가 걸쳐져 체결되는 것이다.Push the enlarged head 24 in which the end of the steel wire or the steel rod 11 is set larger than the diameter of the steel wire or the steel rod as shown in FIG. 8 (c) in the steel wire fastening hole 72 formed as described above. Then, when pushed down to the vertical hole 74 is installed in contact with the lower portion of the circular hole 73, the expansion head 24 of the steel wire or steel rod is fastened to the vertical hole 74 as shown in Figure 8 (b). .

상기와 같이 체결된 강선 또는 강봉(11)을 해체할때에는 반대로 수직구 멍(74)에 체결된 강선 또는 강봉(11)을 위로 올리면 수직구멍(74)보다 직경이 넓은 원형구멍(73)으로 강선 또는 강봉의 확대두부(24)가 올라오면서 원형구멍(73)을 통하여 외부로 빠지게 되는 것이다.When dismantling the steel wire or steel rod 11 fastened as described above, on the contrary, when the steel wire or steel rod 11 fastened to the vertical hole 74 is lifted up, the steel wire is formed into a circular hole 73 having a diameter larger than that of the vertical hole 74. Or as the enlarged head 24 of the steel rod is raised to the outside through the circular hole 73.

이렇게 강선 또는 강봉(11)의 단부를 강선체결지압강판(70)의 강선체결공(72)에 설치하고 강선 또는 강봉을 체결하도록 한 것은 수직지지부(41)와 가동지압강판(60)과의 사이에 설치된 유압잭(34)에 스트로크를 발생시키면 가동지압강판(60)이 외측으로 밀리면서 강봉(32)에 의하여 일체 연결된 강선체결지압강판(70)이 수직지지부(41) 쪽으로 움직이게된다. The end of the steel wire or steel bar 11 is installed in the steel wire fastening hole 72 of the steel wire fastening pressure plate 70 and fastened to the steel wire or steel bar between the vertical support portion 41 and the movable pressure steel plate 60 When the stroke is generated in the hydraulic jack 34 installed in the movable pressure-bearing steel plate 60 is pushed to the outside, the steel wire fastening pressure-bearing steel plate 70 integrally connected by the steel bar 32 is moved toward the vertical support portion 41.

이때 상기 강선체결지압강판(70)에 형성된 강선체결공(72)에 체결된 강선 또는 강봉(11)도 동시에 수직지지부(41) 쪽으로 이동하면 강선 또는 강봉(11)에 긴장력이 도입되게되는 것이다.At this time, when the steel wire or steel rod 11 fastened to the steel wire fastening hole 72 formed in the steel wire fastening pressure plate 70 moves toward the vertical support portion 41 at the same time, a tension force is introduced into the steel wire or steel rod 11.

상기와 같이 강선 또는 강봉(11)에 긴장력이 도입된 상태에서 원하는 부분에만 프리스트레스를 도입하도록 응고시간지연접착수지재를 도포한 다음, 콘크리트를 타설양생하여 거더의 제작이 완료된 후에, 제작이 완료된 거더를 이동하기 위하여 상기 강선체결지압강판(70)에 체결된 강선 또는 강봉(11)을 별도의 해체장비 없이 망치로 수직구멍(74)에 거치된 강선 또는 강봉(11)을 위로 쳐 올리기만 하면 원형구멍(73)으로 이동된 강선 또는 강봉의 확대두부(24)가 원형구멍(73)을 통하여 외부로 간단히 이탈하도록 한 것이다.After applying the coagulation time delay adhesive resin material to introduce the pre-stress only to the desired portion in the state where the tension force is introduced to the steel wire or steel rod 11 as described above, after the concrete is cast and finished the production of the girder, the production girder Simply move the steel wire or steel rod 11 fastened to the steel wire fastening pressure plate 70 to lift the steel wire or steel rod 11 mounted in the vertical hole 74 with a hammer without additional dismantling equipment. The enlarged head 24 of the steel wire or the steel rod moved to the hole 73 is to be easily separated to the outside through the circular hole 73.

즉, 강선 또는 강봉(11)의 체결과 해체를 용이하게 하기 위하여 강선체결공(72)을 열쇠구멍과 같이 설치한 것이다.That is, in order to facilitate the fastening and dismantling of the steel wire or the steel bar 11, the steel wire fastening hole 72 is provided as a key hole.

상기 지반(31)에 설치되는 지지대(40)가 유압잭(34)의 스트로크에 저항하면서 안전하게 거더를 제작할 수 있도록 하기 위한 지지대(40)의 설치조건중에서 전도되지 않고 안전하게 지지될 수 있도록 P x H1〈W x L1가 되어야 한다.P x H1 < so that the support 40 to be installed on the ground 31 can be safely supported without being inverted in the installation conditions of the support 40 for resisting the stroke of the hydraulic jack 34 and making the girders safe. It should be W x L1.

즉, 지지대(40)의 수평지지부(42)를 내측으로 일정길이설치하면, 수직지지부(41)의 외측면의 일정높이(H1)에서 유압잭(14)에 의하여 발생되는 스트로크힘(P)에 의하여 수직지지부(41)가 내측으로 전도되려는 힘에 대항하여 상기 스트로크힘의 작용방향과 반대방향으로 일정길이 내측으로 설치되는 수평지지부(42)의 자체 중량(W)이 작용하는 거리(L1)에 의한 힘보다 작게 하여 지지대(40)가 안전하게 지지되어 거더를 제작할 수 있도록 한 것이다.That is, when the horizontal support portion 42 of the support 40 is provided with a predetermined length inward, the stroke force P generated by the hydraulic jack 14 at a predetermined height H1 of the outer surface of the vertical support portion 41. By the distance (L1) the self-weight (W) of the horizontal support portion 42, which is installed in a predetermined length in the opposite direction to the direction of action of the stroke force against the force that the vertical support portion 41 is to be conducted inwardly Less than the force is to support the support (40) is to make the girder securely.

또한, 상기 지반(31)에 설치되는 지지대(40)가 유압잭(34)의 스트로크에 저항하면서 안전하게 거더를 제작할 수 있도록 하기 위한 지지대(40)의 설치조건중에서 지지대가 활동, 즉 미끄러지지 않도록 하기 위하여 P〈W x μ+C 가 되어야 한다.In addition, in order to prevent the support from being active, that is, slipping, in the installation conditions of the support 40 to allow the support 40 installed on the ground 31 to safely manufacture the girder while resisting the stroke of the hydraulic jack 34. It should be <W x μ + C.

즉, 상기 지지대(40)는 스트로크힘(P)보다 수평지지부(42)의 자체중량(W)과 저면마찰계수(μ)를 곱한 값에 수동토압(C)을 더한 힘이 더 크도록 하여 활동 즉, 지지대(40)가 미끄러지지 않도록 하여야 한다.That is, the support 40 acts to increase the force by adding the manual earth pressure (C) to the value multiplied by the self-weight (W) of the horizontal support portion 42 and the bottom friction coefficient (μ) than the stroke force (P). That is, the support 40 should not slip.

또한, 상기 지반(31)에 설치되는 지지대(40)가 유압잭(34)의 스트로크에 저항하면서 안전하게 거더를 제작할 수 있도록 하기 위한 지지대(40)의 설치조건중에서 지지대(40)의 수직지지부(41)와 수평지지부(42)가 만나는 부분의 단면파괴를 방지하여야 하므로 이를 위하여는 P x h2 /Z〈fa 가 되어야 한다.In addition, the vertical support portion 41 of the support 40 in the installation conditions of the support 40 to enable the support 40 to be installed on the ground 31 to safely manufacture the girder while resisting the stroke of the hydraulic jack 34.

The connection portion 90 is provided with an overlapping portion so that the exposed steel wire 12 installed on the end portion facing the end of the cross section, cross-installing the reinforcing steel bars to cover the overlapping portion, and the fixing clip 83 is installed on the exposed steel wire. The slab structure 80 is formed by placing the slab 84 by forming concrete 37 including the connecting portion 90 and the shear connector 18 installed on the upper portion of the girder.

상기 설치된 빔(81) 위에 프리스트레스트콘크리트합성거더(10)의 양단부가 걸쳐지게 설치하면서 측면이 접하도록 설치하고, 상기 빔(81) 위에 마주보고 설치된 상기 프리스트레스트콘크리트합성거더(10)의 단부에 설치된 노출강선(12)이 겹쳐지도록 겹침부를 설치하고, 상기 겹침부가 감싸지도록 루프철근을 교차설치하고, 상기 노출강선에 정착클립(83)을 설치하여 연결부(90)를 설치하고, Both ends of the prestressed concrete composite girder 10 are installed on the installed beams 81 so that side surfaces thereof are in contact with each other, and the ends of the prestressed concrete composite girder 10 are disposed to face the beams 81. The overlapped portion is installed so that the exposed exposed steel wire 12 is overlapped, the loop reinforcement is installed so that the overlapped portion is wrapped, and a fixing clip 83 is installed on the exposed steel wire to install the connection part 90.

상기 연결부(90)와 거더의 상부에 설치된 전단연결재(18)를 포함한 콘크리트(37)를 타설하여 슬래브를 설치한 슬래브구조체(80)인 것이다.It is a slab structure 80 in which the slab is installed by pouring concrete 37 including the connecting portion 90 and the shear connecting material 18 installed on the upper part of the girder.

상기와 같이 다양한 예에 의하여 설치된 슬래브구조체(80)의 특징은 기둥의 수를 줄여 보다 활용성이 큰 공간을 확보하는 것이며, 프리스트레스트콘크리트합성거더(10)에 작용하는 부모멘트에 의한 거더(10)에 발생된 압축력을 상기 프리스트레스트콘크리트합성거더(10)의 상하면에 선택적으로 설치된 프리스트레스미도입부에 전달되어 압축력이 감소되도록 하여 전체적으로 슬래브에 작용하는 부모멘트를 감소시키도록 한 것으로서 건축물 슬래브 및 교량 슬래브에 적용하도록 한 것이다.The characteristics of the slab structure 80 installed by various examples as described above is to ensure a more usable space by reducing the number of columns, girders 10 by the parent acting on the prestressed concrete composite girder 10 The compressive force generated in) is transmitted to the prestressed non-introduction section selectively installed on the upper and lower surfaces of the prestressed concrete composite girder 10 so that the compressive force is reduced to reduce the parent moment acting on the slab as a whole. To apply.

상기 거더(10)의 단부에 설치된 노출강선(12)에 겹침부와 루프철근 및 정착클립(83)을 설치한 연결부(90)를 설치하고, 추후에 슬래브(84)를 설치하기 위하여 타설되는 콘크리트(37)내에 매입되도록 하여 노출강선(12)이 정착클립(83)에 의하여 슬래브(84)와 일체연결되어 결국 프리스트레스트콘크리트합성거더(10)가 노출강선(12)과 겹침부, 루프철근 및 정착클립(83)에 의하여 슬래브(84)와 일체결합되어 작용하는 하중에 의하여 일체거동하도록 한 것이다.Concrete to be installed in the exposed steel wire 12 installed at the end of the girder 10 to install the connecting portion 90, the overlapping portion, the loop reinforcement and the fixing clip 83, and later to install the slab 84 The exposed steel wire 12 is integrally connected with the slab 84 by the fixing clip 83 so that the prestressed concrete composite girder 10 overlaps with the exposed steel wire 12, the loop reinforcement, and the like. It is to be integrally acted by the load acting integrally coupled to the slab 84 by the fixing clip (83).

또 다른 이유로서는, 상기 거더의 양단부 또는 상하부에 압축력이 발생되는 단면에만 선택적으로 프리스트레스미도입부(25)를 설치한 프리스트레스트콘크리트합성거더(10)를 빔(81)에 거치하면서 정착클립(83)에 의하여 노출강선(12)이 슬래브(84)와 일체거동하도록 연결부(90)를 형성하여 상기 연결부(90)에 발생되는 부모멘트에 의하여 거더(10)에는 압축력으로 작용하여, 상기 작용된 압축력이 프리스트레스미도입부(25)에 전달되면, 상기 전달된 압축력이 감소되어 상기 거더(10)와 연결부(90)에 감소된 압축력이 작용되어 결국 부모멘트의 크기가 작아져 슬래브(84)의 안정성을 증가시키도록 한 것이다. As another reason, the fixing clip 83 is mounted on the beam 81 with the prestressed concrete composite girder 10 having the prestressed non-introduced portion 25 selectively installed only at the cross section where the compressive force is generated at both ends or the top and bottom of the girder. By forming the connecting portion 90 so that the exposed steel wire 12 integrally with the slab 84 by acting as a compressive force to the girder 10 by the parent moment generated in the connecting portion 90, the applied compressive force is When transmitted to the prestressed non-introduction portion 25, the transmitted compressive force is reduced to reduce the compressive force is applied to the girder 10 and the connecting portion 90 to increase the stability of the slab 84 to eventually increase the stability of the slab 84 It was made to be.

도 4에서보는바와 같이, 상기 프리스트레스트콘크리트합성거더(10)를 빔(81) 상부에 설치하면서, 빔과 빔이 측면에서 접하도록 연이어서 설치할 때 상기 거더(10)의 측면에 형성된 전단홈(16)에 의하여 공간부인 전단키가 설치되는 것이다.As shown in Figure 4, while the prestressed concrete composite girder 10 is installed on the beam 81, the shear groove formed on the side of the girder 10 when the beam and the beam is subsequently installed to contact the side ( 16) the shear key which is a space part is installed.

While showing the positional relationship between the range of the pre-stressed non-introduction portion 25 and the inflection point 87 of the government moment generated crosswise to the girder 10, the parent moment generated at the same time is selectively installed in the girder 10. It is shown to be reduced by the pre-stress non-introduction (25).

상기 모멘트도에서보는바와 같이, 슬래브구조체(80)에 설치된 프리스트레스트콘크리트합성거더(10)를 빔에 설치하여 슬래브를 설치한 후에 상기 슬래브에 하중이 작용될때 본 도와 같이 정부모멘트가 상기 거더에 교차적으로 발생하게된다.As shown in the moment diagram, when the load is applied to the slab after installing the slab by installing the prestressed concrete girder 10 installed on the slab structure 80 to the beam as shown in this figure the government moment intersects the girder Will occur as an enemy.

상기 발생된 정부모멘트 중에서 부모멘트가 발생되는 범위에 해당하는 거더의 압축력이 작용하는 상하부에 선택적으로 프리스트레스를 도입하지 않은 부분(25)을 설치하여, 상기 부모멘트에 의하여 거더에 발생되는 압축력이 프리스트레스미도입부(25)에 전달되어 압축력의 크기가 감소되도록 한 것이다. Among the generated moments, a portion 25 in which no prestress is selectively introduced is installed in the upper and lower portions of the girders corresponding to the range where the parent moment is generated, and the compressive force generated in the girder by the parent moment is prestressed. It is transmitted to the non-introduction portion 25 to reduce the amount of compression force.
