The invention provides a safe turnover device for a special-shaped chord member of a steel truss girder and a using method, the safe turnover device comprises an L-shaped turnover rod, the L-shaped turnover rod comprises a first stop rod, one end of the first stop rod is provided with a second stop rod perpendicular to the first stop rod, and the end, away from the second stop rod, of the first stop rod is provided with a first lifting lug; a second lifting lug is arranged at the end, away from the first blocking rod, of the second blocking rod. An adjusting rod is movably fixed on the first stop rod and is parallel to the second stop rod; the number of the L-shaped overturning rods is at least two. The turnover device has the advantages of being simple in structure and high in turnover efficiency, compared with a traditional mode, the turnover radius of the gravity center of the L-shaped turnover rod is smaller in the turnover process, the L-shaped turnover rod turns over in the air, collision and deformation of a steel truss girder rod piece and damage to a coating paint face are avoided, and higher safety is achieved; by adjusting the position of the adjusting rod on the first blocking rod, the steel truss beam overturning device can be suitable for overturning and fixing steel truss beam rod pieces with different sections, applicability is high, operation is convenient and fast, and construction efficiency can be greatly improved.

    本申请提供了一种钢桁梁异形弦杆安全翻转装置及使用方法,包括:L型翻转杆,包括第一档杆,第一档杆的一端垂直于所述第一档杆设置有第二档杆,所述第一档杆远离所述第二档杆的一端设置有第一吊耳,所述第二档杆远离所述第一档杆的一端设置有第二吊耳;第一档杆上可移动固定有调节杆,所述调节杆与所述第二档杆平行;所述L型翻转杆至少有两个。本申请具有结构简单,翻转效率高的特点,相比传统方式,L型翻转杆重心在翻转过程中翻转半径更小,在空中转体翻身,避免钢桁梁杆件碰撞,变形以及涂装漆面受损,具有更高的安全性;通过调整调节杆在第一档杆上的位置,可适用于不同截面钢桁梁杆件的翻转固定,适用性强、操作便捷,可大幅提高施工效率。
