Abstract

본 발명은 프리캐스트 콘크리트 들보의 설치공법에 관한 것으로써, 들보의 자중에 의한 휨모멘트가 이웃한 들보로 분배되도록 함으로써 휨모멘트의 절대값을 작게할 목적으로 일련의 기등위에 걸쳐 재치된 다수개의 프리캐스트 콘크리트 들보의 중앙부에 상향의 힘을 가하여 위로 휘어지게 한 상태에서 들보의 단부 사이의 공간에 콘크리트를 타설하여 경화시키고 들보의 윗면에 설치한 돌기의 구멍을 통해 인장강재를 삽입하여 이것을 인장함과 동시에 상향의 힘을 감소시켜 인장이 완료될때 상향의 힘을 소거하고 인장강재를 정착시키는 것을 특징으로 하는 공법으로서 들보의 자중에 의한 휨모멘트의 절대값이 감소되어 들보의 내하력이 증가되는 효과가 있다.The present invention relates to a method for installing precast concrete beams, in which a plurality of pre-positions are placed over a series of lamps for the purpose of reducing the absolute value of the bending moment by allowing the bending moment due to the weight of the beam to be distributed to neighboring beams. The concrete is placed in the space between the ends of the beams with the upward force applied to the center of the cast concrete beams, and the concrete is placed in the space between the ends of the beams, and the tensile steel is inserted through the holes of the projections installed on the beams. At the same time, the method is characterized by eliminating the upward force and fixing the tensile steel when the tension is completed by reducing the upward force, thereby reducing the absolute value of the bending moment due to the weight of the beam, thereby increasing the load capacity of the beam. .

제 1 도는 들보를 기둥위에 재치시킨 본 발명 제 1 공정의 개략도,1 is a schematic view of the first step of the present invention in which a beam is placed on a column,

제 2 도의 (가) (나) (다)는 들보의 중앙부를 상향으로 휘어지게 하는 본 발명 제 2 공정의 여러가지 실시예로서 (가)는 기중기로 인양하는 경우이고, (나)는 가설기등과 유압잭으로 밀어올리는 경우이고 (다)는 가설들보와 유압잭을 이용한 경우이구 (라)는 들보내부에 설치된 파이프를 관통하여 강선을 인장하므로써 실시되는 경우를 나타낸다,(A) (b) (c) of FIG. 2 are various embodiments of the second process of the present invention which causes the central portion of the beam to be bent upward. And (c) is the case of using the hypothetical beam and the hydraulic jack, and (d) represents the case where the steel wire is pulled through the pipe installed inside the beam.

제 3도는 들보의 중앙부를 휘어지게한 후 들보의 단부를 콘크리트로 연결시킨 상태의 본 발명 제 3공정의 개략도,3 is a schematic view of the third process of the present invention in a state in which the ends of the beams are connected with concrete after the center portion of the beams are bent;

제 4도는 인장부재를 돌기부에 설치한 상태의 본 발명 제 3 공정의 요부발췌도.4 is an excerpt of an essential part of the third step of the present invention with the tension member installed on the protrusion.
