PROBLEM TO BE SOLVED: To provide a plate material connection composer in which yield of the plate material is enhanced by enabling escape of excess force feeding pressure at the time of press-insertion of a joint part provided in the plate material, preventing the plate material from being curved, preventing generation of a step in the joint part and preventing the plate material from being bent. SOLUTION: In the plate material connection composer, the joint parts of both plate materials 2 are press-inserted and connected by respectively clamping and sticking the plate materials 2 in which joint parts are worked in the end parts to be mutually connected, by a stationary clamping machine 11 and a movable clamping machine 12 arranged freely movably forwards and backwards for the stationary clamping clamping machine 11 and by allowing the movable clamping machine 12 to approach and move for the stationary clamping machine 11. A supporting base 13 of the stationary clamping machine 11 and the movable clamping machine 12 is provided. Cover plates A, B and C, D clamping the plate materials 2 from the upper and lower sides are provided in a press-insertion supporting base 17 and in the plate material-clamping faces of clamping plates 16, 22. Such arrangement is obtained that the cover plates A, B and C, D pinch and hold the joint parts of both plate materials 2 from the upper and lower sides at the time of clamping the plate materials. Excess force feeding pressure at the time of press-insertion connection process is escaped by a slip of the cover plates A, B and C, D and the plate materials 2.
