본 발명은 프리스트레스트 콘크리트빔의 낙교방지와 전도방지용 크로스빔 및 이의 시공방법에 관한 것으로, 특히 전도방지 및 낙교방지 역할을 동시에 수행하는 크로스빔의 구조로써 내진 및 내풍에 안정한 프리스트레스트 콘크리트빔의 낙교방지와 전도방지용 크로스빔 및 이의 시공방법에 관한 것이다.The present invention relates to a cross beam for falling prevention and falling prevention of a prestressed concrete beam, and a construction method thereof. In particular, a falling beam of a prestressed concrete beam that is stable to earthquake resistance and wind resistance as a structure of a cross beam that simultaneously performs a falling prevention and falling prevention role. It relates to a cross beam for preventing and falling prevention and a construction method thereof.

일반적으로 프리스트레스트 콘크리트빔 시공은 도 1에 도시된 바와 같이, 각각의 프리스트레스트 콘크리트빔(1) 단부에 와이어로프(2)와 교각 코핑부(3)의 앵커철근(4)으로 이루어진 전도방지장치(5)를 이용하여 프리스트레스트 콘크리트빔(1)의 전도를 방지하면서 교량을 시공한다.In general, the prestressed concrete beam construction, as shown in Figure 1, each prestressed concrete beam (1) end of the fall prevention device consisting of a wire rope (2) and anchor reinforcement (4) of the piercing coping part (3) Use (5) to construct the bridge while preventing the prestressed concrete beam (1) from falling.

여기서, 상기한 바와 같은 전도방지장치(5)는 현재 시공중인 프리스트레스트 콘크리트빔(1) 교량의 대부분의 현장에서 많이 사용하고 있으므로 현장에서의 적용성이 우수한 이점이 있다.Here, the fall prevention device 5 as described above is used in most of the site of the prestressed concrete beam (1) bridge currently in construction, there is an advantage in the applicability in the field.

그러나, 상기한 바와 같은 전도방지장치(5)를 이용한 프리스트레스트 콘크리트빔(1) 시공은 임시로 프리스트레스트 콘크리트빔(1)의 전도방지를 목적으로 하는 전도방지장치(5)를 교각 코핑부(3)에 설치함으로써, 프리스트레스트 콘크리트빔(1) 의 안정성이 떨어짐으로 말미암아 프리스트레스트 콘크리트빔(1)이 전도되는 사례가 빈번한 문제가 있다.However, the construction of the prestressed concrete beam (1) using the fall prevention device (5) as described above is temporarily piercing the fall prevention device (5) for the purpose of preventing fall of the prestressed concrete beam (1) By installing in 3), there is a frequent problem that the prestressed concrete beam 1 is turned over due to the inferior stability of the prestressed concrete beam 1.
