PROBLEM TO BE SOLVED: To provide a construction method of a coating floor, capable of suppressing reduction in durability of the coating floor while preventing cracking of the coating floor.SOLUTION: A construction method of a coating floor, for providing a coating floor part 6 in a concrete floor 3 and a joint part 10 to form a concrete floor 1, includes: a first step S11 of setting a groove width (W) of a groove 9 for a joint and selecting the quality of material of the coating floor part 6 so that a strain (&egr;) generated in the coating floor part 6 is made smaller than a limit strain (&egr;u) of the coating floor part 6 when an amount of change (δ) of a clearance 2 increases; and a second step of selecting the quality of material of the joint part 10 so that a peeling stress generated between the joint part 10 and a side wall 9a of the groove 9 for the joint adhered to each other is made smaller than an adhesive strength (&sgr;bf) of the joint part 10 to the side wall 9a when the amount of change (δ) of the clearance 2 increases. |
