PROBLEM TO BE SOLVED: To provide a floor constructing method which can easily and quickly construct a floor structure in which its wall-end joist is borne by auxiliary posts at a wall end having a heat insulating material sprayed thereon. SOLUTION: According to the method, leveling is carried out while the wall-end joist 3 is separated from a wall surface 1, and the auxiliary posts 6 are erected along the wall-end joist 3 at regular intervals, by inserting a lower end of each auxiliary post 6 into the heat insulating material 11 to make contact with a floor surface 7, and then a side surface 4b of each auxiliary post 6 is rigidly bonded to a side surface 3b of the wall-end joist with a hot-melt adhesive. Next, a protruding portion 4c of the auxiliary post 6, protruding from an upper surface 3c of the wall-end joist 3 is cut by using a special cutter, and an underfloor panel 9 and a floor finish material 10 are laid on the floor joist upper surface 3c and each auxiliary post upper surface 6d which are flush with each other. According to the method, erection of the auxiliary posts on the floor surface on which the heat insulating material 11 is sprayed, is facilitated. In comparison with a method according to which the auxiliary post 6 is inserted into a gap between the wall-end joist 3 and the uneven floor surface 7, the present method facilitates setting of the auxiliary posts with good efficiency.
