PROBLEM TO BE SOLVED: To provide a new method for execution of joint filler capable of cut down process of works in comparison with the conventional execution method and, at the same time, of saving mechanical materials, labor, dangerous work, etc. SOLUTION: A thermoplastic material having such a property as the surface coming into contact with ready mixed concrete is adhered to concrete after the solidification of the concrete is extruded in the shape of a specific section in advance, stripped or tape-like rolls 2 are stucked with sticking rolls 3, 4 and 5 while heating one side of a molded material coming into contact with a joint position of a structural body on the side molded in advance by means of a heater 9a used for hot wind heating, etc., by a truck capable of traveling parallel to a joint made in the concrete and a traveling machine 1 having a device sticking the molded material on the joint position, and then, the opposite concrete is cast, so that the molded material can form the joint adhered to both concrete structural bodies. By the constitution, cutter bit work for making such a conventional joint is not required.
