PROBLEM TO BE SOLVED: To provide a lamination method of a rigid foamed body in which a foaming state of the rigid foamed body foamed by discharging a liquid foaming material on a construction surface is excellent and which has high adhesive strength for the construction surface and generates warp hardly.SOLUTION: A lamination method of a rigid foamed body includes the steps of: spraying a first liquid foaming material 15A onto a foundation 13 as a construction surface; pressing a plate-like body 17 of a thermosetting resin foam body against the first liquid foaming material 15A on the surface of the foundation 13; in this state, advancing a reaction of the first liquid foaming material 15A on the surface of the foundation 13 to bond the plate-like body 17 to the surface of the foundation 13; thereafter discharging a second liquid foaming material onto the foundation 13 so as to cover the plate-like body 17 on the surface of the foundation 13; and foaming the second liquid foaming material to laminate the rigid foamed body bonded to the plate-like body 17 onto the foundation 13. |
