이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 4 이하에 도시된 바와 같이, 본 발명에 의한 거더의 상부 보강부재(A)는 기본적으로, 거더(10)의 상부 플랜지(11)에 길이방향으로 설치되는 본체(100); 거더(10)의 웹(12)을 상부로부터 다짐작업할 수 있도록, 본체(100)의 심부에 형성된 다짐작업용 중공부(200);를 포함하여 구성된다.As shown in Figure 4 below, the upper reinforcing member (A) of the girder according to the present invention basically, the main body 100 is installed in the longitudinal direction on the upper flange (11) of the girder (10); And a compaction work hollow portion 200 formed in the core portion of the main body 100 so as to compact the web 12 of the girder 10 from the top.

즉, 거더(10)의 상부 플랜지(11)에 보강부재(A)를 설치하되, 그 보강부재(A)의 심부에 중공부(200)를 형성함으로써, 거더(10)의 웹(12)에 대한 콘크리트의 충전 및 다짐작업을 원활히 수행할 수 있도록 한 것이다.That is, the reinforcing member A is installed in the upper flange 11 of the girder 10, but the hollow portion 200 is formed in the core portion of the reinforcing member A, thereby providing the web 12 of the girder 10. It is to facilitate the filling and compacting of concrete.

따라서 상부 플랜지에 보강부재를 합성하여 형고를 줄이면서도, 웹에 대한 콘크리트의 충전 및 다짐작업을 용이하게 할 수 있도록 하여 우수한 품질의 거더를 제조할 수 있다는 효과가 있다.Therefore, while reducing the mold height by synthesizing the reinforcing member to the upper flange, it is possible to facilitate the filling and compacting of the concrete for the web has an effect that can produce a good quality girders.

상부 보강부재(A)의 본체(100)는 심부에 중공부(200)가 형성되는 구조이면 어느 것이나 관계없으나, 다짐작업용 중공부(200)를 중심으로 양측에 길이방향으로 설치되는 한 쌍의 보강부(110); 한 쌍의 보강부(110)를 상호 연결하는 연결부(120);를 포함하는 구조를 취하는 것이 구조적 안정성 측면에서 바람직하다(도 4).The main body 100 of the upper reinforcing member (A) may be any structure as long as the hollow portion 200 is formed in the core portion, but a pair of reinforcement is installed in the longitudinal direction on both sides with respect to the hollow portion 200 for compaction work Part 110; It is preferable in terms of structural stability to take a structure including a; connecting portion 120 interconnecting a pair of reinforcing portion (110) (Fig. 4).

여기서, 보강부(110)는, 거더(10)의 상부 플랜지(11)의 상면에 노출되도록 가로방향으로 설치되는 가로판(111); 가로판(111)의 하면에 세로방향으로 연장설치되는 세로판(112);을 포함하는 구성을 취함으로써, 전체적으로 "T"자형 구조에 의해 거더의 압축응력을 부담하도록 하고, 세로판(112)이 상부 플랜지(11)에 매설되도록 하여 안정적인 부착을 이루도록 하는 것이 바람직하다.Here, the reinforcement portion 110, the horizontal plate 111 is installed in the horizontal direction so as to be exposed to the upper surface of the upper flange 11 of the girder 10; The vertical plate 112 which extends in the longitudinal direction on the lower surface of the horizontal plate 111; taking a configuration including, so as to bear the compressive stress of the girder by the "T" shaped structure as a whole, the vertical plate 112 It is preferable to embed the upper flange 11 to achieve a stable attachment.

보강부(110)가 위와 같은 구조를 취하는 경우, 이들 한 쌍의 보강부(110)를 상호 연결하기 위한 연결부(120)는, 한 쌍의 보강부(110)의 세로판(112)을 상호 연결하도록 세로방향으로 설치되는 세로연결판(121)의 구조를 취하여 상부 플랜지(10)에 매설되도록 하는 것이 보강부재(A)와 상부 플랜지(11)의 안정적인 부착구조를 이룰 수 있다는 측면에서 바람직하다(도 5).When the reinforcement part 110 has the above structure, the connection part 120 for interconnecting the pair of reinforcement parts 110 interconnects the vertical plates 112 of the pair of reinforcement parts 110. It is preferable to take the structure of the vertical connecting plate 121 which is installed in the longitudinal direction so as to be embedded in the upper flange 10 in terms of achieving a stable attachment structure of the reinforcing member A and the upper flange 11 ( 5).

보강부(110)의 세로판(112)은 상부 플랜지(10)에 매설되는데, 이러한 세로판(112)에 복수의 관통공(113)이 형성되는 경우, 이 관통공(113)에 상부 플랜지(10)의 콘크리트가 충전되거나, 배근이 관통하여 설치되도록 할 수 있으므로, 더욱 우수한 부착을 이룰 수 있다는 장점이 추가된다(도 6).The vertical plate 112 of the reinforcement part 110 is embedded in the upper flange 10. When the plurality of through holes 113 are formed in the vertical plate 112, the upper flanges are formed in the through holes 113. 10) the concrete can be filled, or the reinforcement can be installed to penetrate, it is added that the advantage that can achieve a better adhesion (Fig. 6).

보강부(110)의 가로판(111)의 상면에 복수의 스터드(114)가 돌출되도록 설치되는 경우, 거더의 상부에 설치되는 교량의 상판과의 부착강도를 높일 수 있다는 장점이 추가된다(도 7).When the plurality of studs 114 are installed to protrude from the upper surface of the horizontal plate 111 of the reinforcement unit 110, an advantage of increasing the adhesion strength with the upper plate of the bridge installed on the top of the girder is added (Fig. 7).

본 발명에 의한 거더의 상부 보강부재(A)는 하부 플랜지(13)에 긴장재(20)가 설치되어 프리스트레스 힘이 인가된 PSC 거더에 설치되어 상술한 바와 같은 효과를 얻을 수 있음은 물론(도 8,9), 일반 거더에 설치되더라도 위와 대동소이한 효과를 얻을 수 있다.The upper reinforcing member (A) of the girder according to the present invention is provided on the lower flange 13, the tension member 20 is installed on the PSC girder to which the prestressing force is applied to obtain the effect as described above (Fig. 8) , 9) Even if it is installed in the general girder, the same effect as above can be obtained.

이상은 본 발명에 의해 구현될 수 있는 바람직한 실시예의 일부에 관하여 설명한 것에 불과하므로, 주지된 바와 같이 본 발명의 범위는 위의 실시예에 한정되어 해석되어서는 안 될 것이며, 위에서 설명된 본 발명의 기술적 사상과 그 근본을 함께 하는 기술적 사상은 모두 본 발명의 범위에 포함된다고 할 것이다.Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
