Zusammenfassung:Disclosed is a concrete synthesized girder. The concrete synthesized girder comprises: a plurality of perforated bond holes provided in a vertical reinforcement material; a washer unit coupled to the perforated bond holes at preset length and provided in a hollow cylindrical shape; and a steel rod coupled to the hole of the washer unit without tolerance. Filling of concrete is excluded in the hole of the washer unit, so that generation of concrete bearing failure is blocked in the hole of the perforated bond hole and the hole of the washer unit. 콘크리트가 합성되는 거더가 개시된다. 콘크리트가 합성되는 거더는, 수직보강재에 다수 개 마련되는 퍼포본드 홀, 미리 설정된 길이로 퍼포본드 홀에 결합되며, 중공의 원통형으로 마련되는 와셔부, 와셔부의 홀에 공차없이 결합되는 철근을 포함하며, 와셔부 홀 내에는 콘크리트의 충진이 배제되어 퍼포본드 홀 및 와셔부의 홀에 콘크리트 지압파괴의 발생이 차단된다.
