Steel wire, PC steel bar, PC steel twisted wire, etc.
또한 상기 텐던(1)을 제1PSC빔(110) 및 제2PSC빔(120)의 외측면에 고정시키기 위한 수단으로서, 텐던(1)의 양측에 고정부(2)(2A)가 형성되고, 상기 고정부(2)(2A)에 의한 텐던(1)의 고정을 위해 제1PSC빔(110) 및 제2PSC빔(120) 제작시 상기 제1PSC빔(110) 및 제2PSC빔(120)에 시스관(sheath tube) 등으로 고정공(20)이 형성된다.In addition, as a means for fixing the tendon 1 to the outer surface of the first PSC beam 110 and the second PSC beam 120, fixing parts (2) (2A) are formed on both sides of the tendon (1), In order to fix the tendon 1 by the fixing parts 2 and 2A, sheath pipes are formed on the first PSC beam 110 and the second PSC beam 120 when the first PSC beam 110 and the second PSC beam 120 are manufactured. The fixing hole 20 is formed by a sheath tube or the like.
고정부(2)(2A)는 사각형상의 판체로 된 고정판(21)으로 구성되고, 상기 고정판(21)의 외곽에는 제1PSC빔(110) 및 제2PSC빔(120)의 외측면에 다수 형성된 고정공(20)과 일치되어 고정핀(23)으로 고정되는 조립공(21A)이 다수 형성된다.Fixing part (2) (2A) is composed of a fixing plate 21 made of a rectangular plate body, the fixing plate 21 is formed on the outer surface of the first PSC beam 110 and the second PSC beam 120 in the outer portion of the fixing plate 21 Matching the ball 20 is formed with a plurality of assembly holes (21A) fixed by the fixing pin (23).
그리고 상기 고정판(21)의 일측면, 즉 외측면 중앙에는 고리형태로 된 고정구(22)가 일체로 형성되고, 상기 고정구(22)의 중앙부에는 삽입공(22A)이 전.후방측으로 관통 형성되어 상기 삽입공(22A)에 텐던(1)의 양단부가 삽입되어 고정수단에 의해서 고정될 수 있도록 구성한 것이다.In the center of one side of the fixing plate 21, that is, the outer surface, an annular fastener 22 is integrally formed, and an insertion hole 22A is formed in the center of the fastener 22 through the front and rear sides. Both ends of the tendon (1) is inserted into the insertion hole (22A) is configured to be fixed by the fixing means.
이와같이 구성된 본 고안은 먼저, 도 2에 도시된 바와 같이 제1PSC빔(110) 및 제2PSC빔(120)을 제작한 후, 슬래브(130)에 철근(140)을 배치하고, 슬래브 콘크리트를 타설하여 양생시킨다. 그런 다음 제1PSC빔(110) 및 제2PSC빔(120) 제작시 상기 제1PSC빔(110) 및 제2PSC빔(120)의 외측면에 함께 형성된 고정공(20)에 고정판(21)의 조립공(21A)을 일치시킨 후, 고정핀(23)으로 박아 고정한다.The present invention configured as described above, first, as shown in Figure 2, after producing the first PSC beam 110 and the second PSC beam 120, the reinforcing bar 140 is placed on the slab 130, and the slab concrete is poured Curing Then, when fabricating the first PSC beam 110 and the second PSC beam 120, the assembling hole of the fixing plate 21 in the fixing hole 20 formed together on the outer surface of the first PSC beam 110 and the second PSC beam 120 ( After coinciding with 21A), drive the pins 23 to fix them.
그 후, 일정길이의 환봉으로 형성된 텐던(1)의 양단부측을 고정부(2)(2A)의 고정판(21) 중앙에 형성된 고정구(22)의 삽입공(22A)에 각각 삽입하게 되고, 이 상태에서 긴장, 즉 외부 텐션작업이 이루어지게 되며, 고정수단을 이용하여 고정함으로써 일련의 조립을 완료하게 되는 것이다.Thereafter, both end portions of the tendons 1 formed by round rods having a predetermined length are respectively inserted into the insertion holes 22A of the fasteners 22 formed in the center of the fixing plate 21 of the fixing parts 2 and 2A. In the state of tension, that is, the external tension work is made, and by using a fixing means to complete a series of assembly.
상술한 바와 같이 본 고안은 긴장재인 텐던을 PSC빔의 외측에 긴장시킬 수 있도록 구성함으로써 상기 텐던의 설치 및 해제가 용이할 뿐만 아니라 재긴장 및 추가긴장이 가능하고, 또한 슬래브에 압축력 도입시 압축력의 불연속 구간이 발생되지 않음은 물론 슬래브의 콘크리트 설계기준 강도가 서로 상이함이 없이 동일하게 나타나는 효과가 있다.As described above, the present invention is not only easy to install and release of the tendon but also to re-tension and additional tension by configuring the tendon, which is a tension material, to be tensioned on the outside of the PSC beam. Discontinuity does not occur, as well as the concrete design reference strength of the slab has the same effect without appearing to be different.
