PROBLEM TO BE SOLVED: To provide a method for connecting liner plates by which labor saving of construction becomes possible by reducing the number of operators when the liner plates are connected with each other, and it becomes possible to perform the construction in short time.SOLUTION: In a method for connecting liner plates for connecting the liner plates 20 having circumferential flanges 22 in which first holes 22a are drilled at upper ends and lower ends, the liner plates are temporarily fastened in a state in which the first holes 22a, 22a of the respective circumferential flanges 22, 22 are aligned by inserting a temporary fastener into a second hole 22b which is formed in the circumferential flange 22 of a liner plate 20-1 and has a diameter different from that of the first hole 22a, and inserting the temporary fastener 3 into the second hole 22b which is formed in the circumferential flange 22 of a liner plate 20-2 and has a diameter different from that of the first hole 22a, and fastening fittings are inserted into the first holes 22a, 22a of the respective circumferential flanges 22, 22 to connect the respective circumferential flanges 22 with each other via the fastening fittings.SELECTED DRAWING: Figure 10 【課題】ライナープレート同士を連結する際の作業員の数を削減して施工の省力化が可能となり、施工を短時間で行うことが可能となるライナープレートの連結方法を提供する。【解決手段】第１孔２２ａが穿設された周方向フランジ２２を上端及び下端に有するライナープレート２０同士を連結するためのライナープレートの連結方法であって、ライナープレート２０−１の周方向フランジ２２に形成されるとともに第１孔２２ａの径と異なる径を有する第２孔２２ｂに仮止め具を挿通し、ライナープレート０−２の周方向フランジ２２に形成されるとともに第１孔２２ａの径と異なる径を有する第２孔２２ｂに、仮止め具３を挿通することで、各々の周方向フランジ２２、２２の第１孔２２ａ、２２ａが位置合わせされた状態で仮止めし、各々の周方向フランジ２２、２２の第１孔２２ａ、２２ａに締結金具を挿通し、締結金具を介して各々の周方向フランジ２２を連結する。【選択図】図１０
