A TEMPORARY BRIDGE AND CONSTRUCTION METHOD FOR THE TEMPORARY BRIDGE
Provided is a temporary bridge. The purpose of the present invention is to provide the temporary bridge to which prestress is applied, wherein a section in which a cross section reinforcing material is attached and a section in which the cross section reinforcing material is not attached are differently applied in accordance with a span in an I-beam for a center and an I-beam for a support. According to an embodiment of the present invention, the temporary bridge includes: the at least two I-beams for a support, installed in the upper part of a pier; and a girder including the I-beam for a center, installed between the I-beams for a support. The I-beam for a support and the I-beam for a center include: an upper flange; a lower flange, and a web connecting the upper flange and the lower flange. The I-beam for a support and the I-beam for a center is prestressed, and the cross section reinforcing material for a support is attached to the upper part of the web in the I-beam for a support. The cross section reinforcing material is attached to the lower part of the web in the I-beam of a center. Following equation (1) and equation (2) can be established when the span of the girder is L, the length of the cross section reinforcing material for a center is L_1, and the length of one of the cross section reinforcing material for a support is L_2. L_1= L x (0.2-0.3) - equation (1) L_2= L x (0.1-0.2) - equation (2).
가설교량이 제공된다. 일 실시예에 있어서, 상기 가설교량은 교각의 상부에 설치되는 적어도 두 개의 지점부용 I형강 및 상기 지점부용 I형강 사이에 설치되는 중앙부용 I형강을 포함하는 거더를 포함하는 가설교량에 있어서, 상기 지점부용 I형강과 상기 중앙부용 I형강은 상부 플랜지, 하부 플랜지, 및 이들을 연결하는 웹을 포함하고, 상기 지점부용 I형강 및 상기 중앙부용 I형강은 프리스트레스(Prestress)가 도입되되, 상기 지점부용 I형강은 지점부용 단면보강재가 상기 웹의 상부에 부착되고, 상기 중앙부용 I형강은 중앙부용 단면보강재가 상기 웹의 하부에 부착되며, 상기 거더의 지간장을 L, 상기 중앙부용 단면보강재의 길이를 L, 상기 지점부용 단면보강재 하나의 길이를 L라고 할 때, 하기 식 (1) 및 식 (2)가 성립할 수 있다. L= L x (0.2~0.3) - 식 (1) L= L x (0.1~0.2) - 식 (2)
