As shown in FIG. 3, the heat insulating material 10 is a substantially rectangular plate-shaped material obtained by forming a heat insulating material into a predetermined plate thickness (here, 25 mm). The heat insulating material 10 is formed with notches 11 that are notched so that the corners of the top plate 20 can be fitted into the four corners. In addition, due to the notches 11 of the heat insulating material 10, recesses 16 are formed at the four corners of the back surface of the floor panel 12.

  The plate-shaped heat insulating material 10 is preferably excellent in heat insulating properties and durability and can be easily cut. For example, a synthetic resin foam having closed cells such as a polystyrene foam, a polyethylene foam, and a polyurethane foam is suitable. In particular, extruded polystyrene (trade name “Styrofoam” (registered trademark): manufactured by Dow Chemical Co., Ltd.) is particularly suitable because of its high heat insulation and low water absorption.

  The floor panel 12 is a rectangular plate made of softwood plywood. The floor panel 12 has a real portion 14 formed on one side surface among the four side surfaces, and a groove portion 15 formed on a parallel side surface provided on the opposite side to the side surface. The floor panel 12 has a shape in which a flat flat surface portion 13 is formed on the remaining two side surfaces. The floor panel 12 is made of softwood plywood having a predetermined plate thickness (here, 24 mm or 28 mm). This softwood plywood has excellent characteristics such as low cost, excellent dimensional stability, bending and tensile strength, and light weight.

  As shown in FIG. 4, the floor base material 6 is formed by fixing a heat insulating material 10 to the back surface of the floor panel 12. In this fixing, a method of applying an adhesive in a scattered manner may be used, but a method by a pinned pin with a staple pin or the like is preferable.

  At this time, the heat insulating material 10 of the floor base material 6 is attached so as to protrude slightly from one side surface or two side surface ends of the back surface portion of the floor panel 12, and the other floor panel 12 adjacent to the floor panel 12 is attached. The heat insulating material 10 is housed and attached a little closer to the inside (W) from the end of the back surface of the panel. In this way, the joint portion (gap) between the floor panels of the floor base material and the joint portion (gap) between the heat insulating materials do not communicate with each other. Can be maintained. In the form in which the two side surfaces are protruded, a form in which two orthogonal side surfaces are protruded and the remaining two side surfaces are respectively stored closer to the inside is preferable. In this case, all the side joints of the floor base material 6 are sealed, and only one type of the heat insulating material 10 is required, which is reasonable.

  As shown in FIG. 5, the support leg 4 includes a column base portion 18 and a top plate 20 with a level adjustment function (turnbuckle configuration) capable of height adjustment. The column base portion 18 is made of steel, and includes a receiving portion 22 having a rectangular receiving plate fixed to the upper portion of the supporting bolt, a pedestal portion 24 having a seat plate fixed to the lower portion of the supporting bolt, and a hollow barrel-shaped buckle.

The support leg 4 has a support bolt of the receiving portion 22 screwed into a screw hole on one side of the buckle portion 26 and fastened by a nut 27, and a support bolt of the pedestal portion 24 is screwed on the other screw hole. It is screwed and fastened with a nut 27.

  The top plate 20 is made of a plywood having a long rectangular shape (here, 100 mm × 600 mm), and is a plate material having a predetermined plate thickness (here, 24 mm). The top plate 20 is fixed to a receiving plate of a receiving portion 22 provided on the top of the column base portion 18. At this time, the receiving plate is fixed with screws (for example, course threads) or the like.

  When constructing the floor having the heat insulating floor structure, first, the support legs 4 are arranged on the floor slab 2 at a predetermined interval. These support legs 4 are arranged in such a form that the four corners of the floor panel 12 of the floor base material 6 can be supported by the support legs 4 respectively. Each support leg 4 is secured to the floor slab 2 with an adhesive on the back surface of the pedestal portion 24 and is fixed together with a fastening tool such as a concrete screw.

  Then, the height level of each support leg 4 is adjusted. At this time, a tool is interposed in the buckle part 26 of the column base part 18 and the buckle part 26 is rotated to expand and contract the support leg 4 to adjust to a predetermined height level. The long top plates 20 of the respective support legs 4 are arranged in parallel with each other with their long directions facing in the same direction.

  Next, as shown in FIG. 6, the floor base material 6 is placed on the top plate 20 of each support leg 4.

Thus, the strength of the side surface portion on which the flat surface portion 13 is formed is ensured.

  Moreover, although the above-mentioned pair of flat surface portions 13 are formed on the floor panel 12 of the floor base material 6, if all the four side surfaces are fitted with the real portions and the groove portions, the strength of the four side surfaces is reinforced, This is because there are many restrictions in the construction, making the construction difficult, and in the case of refurbishment, particularly in the case of partial refurbishment, it is difficult to detach the floor base material 6 and the work is troublesome.

  The floor base material 6 placed and placed on top of each of the support legs 4 fixes the floor panel 12 to the top plate 20 of the support legs 4 using a screw such as a coarse thread. Then, the floor finishing material 8 is laid by bonding on the upper part of the floor base material 6 arranged side by side to finish the floor. 7 and 8, the heat insulating floor structure shown in FIGS. 7 and 8 is provided with notches 11 cut out so that one side portion of the top plate 20 of the floor support leg 4 can be fitted in each of the two corners of the heat insulating material 10. The form which does not provide a notch part in these two corners is shown.

  Therefore, according to the above embodiment, the floor base material in which the number of parts is small, the structure is simple, the workability is excellent, the squeaking noise is prevented in addition to the heat insulating effect, and the heat insulating material and the floor panel are integrated. Since it is used, the cost is reduced as compared with the case where the heat insulating material and the floor panel are transported separately, and the laying work is easy and the work can be shortened. In addition, the top plate of the support leg is formed in a long shape, and the real part and the groove of the floor panel of the floor base material placed on the support leg are below the floor so as to be orthogonal to the long direction of the top plate. Since the ground material is arranged, the floor base material is prevented from being bent, and there is an effect that floor noise due to the load after construction and squeaking noise are prevented.
