    • PURPOSE: A length-variable temporary bridge using steel beams and a construction method thereof are provided to easily control the length of steel beams without loss of material and to enable recycle of the steel beams without area reduction. CONSTITUTION: A construction method of a length-variable temporary bridge(100) is as follows. Studs(112) welded to both ends of a central segment(110) are connected to studs(122) welded to end segments(120) using splice plates(130) and nuts(135). The end segments are connected corresponding to the designated length of the temporary bridge. An intermediate anchoring device(180) is fixed to the central segment and end anchoring devices(150) are installed on the end segments so that the load resistance is enhanced by tension members(152).
    • 目的:提供一种使用钢梁的长度可变的临时桥梁及其施工方法,以便轻松控制钢梁的长度,而不会损失材料,并且能够在不减少面积的情况下回收钢梁。 构成:长距离临时桥梁(100)的施工方法如下。 焊接到中心段(110)的两端的螺柱(112)使用接合板(130)和螺母(135)连接到焊接到端部段(120)的螺柱(122)。 端段相应于临时桥的指定长度连接。 中间锚固装置(180)固定到中心部分,并且端部锚定装置(150)安装在端部段上,使得由张力构件(152)增强负载阻力。
