The present invention relates to an assembly structure of a structural frame part for forming a structure using a grooved PC beam member on which a joist of a PC slab member can be placed, and a construction method thereof.

종래의 피씨슬래브는 본 출원인이 제시한 등록특허 10-0807395에 기재된 바와 같이, 도1을 참조하면, 직사각형상의 평판(62)의 하부에 2개의 보강리브(64)가 형성되고 상기 평판(62)의 양단부에는 지지부(66)가 형성된 더블티형 피씨슬래브부재(60) 다수개를, 도2에서와 같이 중앙 상면에 노출철근(56)이 돌출된 피씨하프보(50)의 걸림부(54)에 거치한다.In the conventional PC slab, as described in the Applicant's Patent Registration No. 10-0807395, referring to FIG. 1, two reinforcing ribs 64 are formed below the rectangular flat plate 62 and the flat plate 62 is formed. At both ends, a plurality of double T-type PC slab members 60 having a support 66 formed thereon are connected to the catching portion 54 of the PC half beam 50 in which the exposed reinforcing bar 56 protrudes from the center upper surface. Mount it.

즉, 상기 더블티형 피씨슬래브부재(60)의 평판(62)의 지지부(66)를 상기 피씨하프보(50)의 걸림부(54)에 얹혀지게한 후, 상기 피씨하프보(50)와 더블티형 피씨슬래브부재(60)의 상부에 철근을 배근하고 그 상부에 토핑콘크리트를 타설하여 슬래브구조 가 완성되는 것이다.That is, the support part 66 of the flat plate 62 of the double T-type PC slab member 60 is placed on the locking part 54 of the PC halfbo 50, and then doubled with the PC halfbo 50. The slab structure is completed by placing the reinforcing bar on the upper portion of the T-type PC slab member 60 and placing the topping concrete on the upper portion thereof.

첫째, 본 발명은 기존 유사 구조물 들의 피씨슬래브와 피씨보가 만나는 부분을 기존의 단순접합에서 연속접합으로 개선하여 균열 발생을 억제함으로써 구조물이 완공된 후의 사용성을 극대화시킬 수 있다. First, the present invention can maximize the usability after the structure is completed by improving the portion where the PC slab and the PC-Bo meets existing similar structures from the conventional simple joint to the continuous joint to suppress the occurrence of cracks.

또한, 상기 연속접합으로 인해 기존의 단순접합시 균열 유도를 위해 바닥슬래브 상부에 타설되는 무근 콘크리트 및 쏘 커팅(Saw Cutting)을 없앰으로써 사용성, 공기단축 및 경제성을 높아지고, 현장 시공성을 크게 향상시킬 수 있다.In addition, the continuous joining eliminates the plain concrete and saw cutting placed on the top of the floor slab to induce cracking during the conventional simple joining, thereby increasing usability, air shortening and economic efficiency, and greatly improving field workability. have.

둘째, 장선의 하부폭은 최소화하고, 상부폭을 넓힘으로써 피씨슬래브부재를 장경간화 할 수 있는 장점이 있다.Secondly, the lower width of the joist is minimized, and the upper slab width can be made longer by increasing the upper width.

넷째, 장선일체형 피씨슬래브 부재를 생산하는 측면에서 보면, 종래에는 장 선을 연속화시키기 위해서는 피씨슬래브의 단부를 테두리보의 형태로 막거나, 장선의 폭을 키워 연속접합에 적합한 적정폭을 확보하여야 한다. Fourthly, in view of producing a long wire integrated PC slab member, conventionally, in order to continuous the long wire, the end of the PC slab should be closed in the form of a rim beam, or the width of the long wire should be increased to secure an appropriate width for continuous joining. .

그러나 전자의 경우 부재별로 개별몰드를 만들어야 하므로 피씨부재의 생산성이 현격히 떨어지게 되며, 후자의 경우에는 불필요한 단면이 많이 소요되게 된다. 따라서, 연속접합을 가능하게 하고 불필요한 장선부위의 단면을 줄이기 위해서는 본 발명에서 제시한 피씨슬래브부재(10)의 역 사다리꼴 단면 형태가 가장 바람직하다.However, in the former case, since the individual molds must be made for each member, the productivity of the PC member is significantly reduced, and in the latter case, unnecessary cross sections are required. Therefore, the inverted trapezoidal cross-sectional shape of the PC slab member 10 proposed in the present invention is most preferable in order to enable continuous joining and reduce unnecessary cross sections of the joists.

이와 같은 형태의 선정에 따라 피씨부재는 부재별 개별몰드가 아닌 여러 부재 연속형 몰드를 사용할 수 있고, 이는 롱라인(Long Line) 생산에 적합한 형태로되어 피씨부재의 생산성을 크게 높일 수 있고, 현장여건에 따라 여러 가지 길이가 다른 피씨부재를 손쉽게 생산하고 대처할 수 있는 각별한 효과가 얻어지게 된다.According to the selection of this type, the PC member can use various member continuous molds instead of individual molds for each member, which is suitable for long line production and can greatly increase the productivity of the PC member. Depending on the conditions, special effects can be obtained to easily produce and cope with different lengths of PC members.

지금까지 본 발명을 바람직한 실시예로서 설명하였으나, 본 발명은 이에 한정되지 않고 발명의 요지를 이탈하지 않는 범위 내에서 다양하게 변형하여 실시할 수 있음은 물론이다.While the present invention has been described as a preferred embodiment, the present invention is not limited thereto, and various modifications can be made without departing from the gist of the invention.
