It has a heat insulating structure in which a heat insulating block made of foam resin is fitted.

  Accordingly, the floor slab F of the illustrated Western-style room has a heat insulation structure that clears the legally-stipulated heat insulation performance standard value in the range of a predetermined width (for example, 45 cm) from the wife-side wall W in accordance with the energy saving method. Therefore, the first floor base X having high heat insulation performance is installed on the floor edge f1 near the wall, while the floor center part f2 excluding the floor edge f1 has a second impact resistance performance exclusively. The floor structure is provided with a floor base Y. Accordingly, the first floor foundation X and the second floor foundation Y are installed on the floor slab F so that the upper surfaces x and y are flush with the upper surface e of the joist E when the level reference is used. The structure is such that one floor base B is constructed by being integrally connected by the connecting means A. After constructing this floor foundation B, the floor surface is finished by laying a plurality of floor finishing plates P on the upper surfaces x and y of the first floor foundation X and the second floor foundation Y as a flooring material for Western-style rooms. To.

  Now, in detail, as shown in FIGS. 2 and 3, the first floor base X is provided with a large number of level adjusting mortar dangos 5 on the floor slab F, and is insulated on the mortar dangos 5. The panel 10 is placed and spread on the floor edge f1.

  As for the mortar dango 5, the mortar in a state where the viscosity is maintained is rolled up one by one in the shape of a dumpling and installed on the floor slab F, and the heat insulation panel 10 is placed on the mortar dango 5. Therefore, when the mortar dango 5 is pushed downward through the heat insulation panel 10, its upper side is crushed according to the viscosity, and as a result, the height position of the heat insulation panel 10 can be adjusted and dried over time. The lower side is integrated with the floor slab F and has a function of bonding the heat insulating panel 10 onto the floor slab F.

  The heat insulating panel 10 includes a heat insulating material 15 and a pier 20 provided on the surface of the heat insulating material 15. The heat insulating material 15 is made of a foamed resin. Among them, the heat insulating material 15 in the illustrated example is made of a foam molded product made of a foamed bead method polystyrene foam which does not contain any harmful chlorofluorocarbon, formaldehyde, acetaldehyde, and toluene. Formed into a rectangular shape. On the other hand, the pier 20 is made of a hard thermoplastic foam resin. Among them, the pier 20 in the illustrated example is made of a rigid foam bead method polystyrene foam which does not contain any harmful chlorofluorocarbons as the heat insulating material 15. It is made of a product and molded into a rod shape with a rectangular cross section. The heat insulating panel 10 in the illustrated example has two piers 20 arranged in the longitudinal direction of the heat insulating material 15 and arranged in parallel in the short direction, with the upper surface facing the outside from the upper surface of the heat insulating material 15. 15 embedded.

  Therefore, the first floor base X is coated with an adhesive such as a primer on the floor edge f1 in the floor slab F, and then a large number of mortar dangos 5 are installed on the bonding surface. The heat insulation panel 10 is placed on the mortar dangos 5..., And the level of the heat insulation panel 10 is adjusted by pressing down the heat insulation panel 10 and crushing the mortar dango 5 with the upper surface e of the joist E as a reference line. After that, the process of installing the adjacent heat insulating panel 10 'on the floor edge part f1 of the floor slab F through the mortar dango 5 ... is repeated in the same manner. By laying 10 'on the floor edge f1, the floor edge f1 has a heat insulation structure that clears the legal heat insulation performance standard value within a predetermined width range from the wall W on the wife side.

  In the floor foundation B according to the present invention, on the floor slab F, the thermal insulation panel 10 is spread on the floor edge part f1 at the wall which needs to have a thermal insulation structure that has cleared the legal thermal insulation performance standard value as described above. After the first floor base X to be formed is installed, the second floor base Y is installed in the floor center part f2 excluding the floor edge part f1 as follows.

  As shown in FIG. 4, the second floor base Y has a plurality of support legs 25 erected on the floor slab F and receives and supports the base panel 30 with the support legs 25. It has a structure in which the upper floor is arranged so that there is a space above which facilitates piping and wiring. As shown in FIG. 5, the support leg 25 includes a vibration-proof base 26 made of an elastic material such as rubber, and a lower end screwed onto the vibration-proof base 26 so that the support leg 25 can freely rotate on the base 26. The support bolt 27 is provided, a hat-shaped cylindrical adjustment nut 28 screwed to the upper end of the support bolt 27, and a rectangular receiving plate piece 29 fixed to the adjustment nut 28 and supported by the support bolt 27. Become.

  The support bolt 27 is provided with a minus groove 27a at the upper end surface, and adjusts the height position of the receiving plate piece 29 by raising and lowering the adjustment nut 28 by inserting and rotating the tip of a rotary tool such as a driver. . In the adjusting nut 28, the cylindrical portion 28a is fitted into an insertion hole 29a formed in the receiving plate piece 29, and the receiving plate piece 29 is attached by adhering the annular flange portion 28b to the peripheral edge of the insertion hole 29a. As shown in FIG. 4, the support leg 25 is assembled by screwing the upper end of the support bolt 27 on the vibration isolation base 26 into the cylindrical portion 28 a of the adjustment nut 28 that is integrated with the receiving plate piece 29.

  The base panel 30 is made of, for example, a particle board having a thickness of 40 mm and a rectangular shape in plan view. The base panel 30 is not limited to a particle board, and wood-based board materials such as various types of plywood can also be used.

  Therefore, the second floor base Y has the vibration-proof base 26 bonded on the floor slab F, and a plurality of support legs 25 are erected, and then the tip of the rotary tool is fitted into the minus groove 27a. Then, by rotating the support bolt 27, the receiving plate pieces 29 are moved up and down to adjust the height of each receiving plate piece 29, and the upper surface of each receiving plate piece 29 is made to coincide with the same horizontal plane as the upper surface e of the joist E. After that, the base panel 30 is placed on the receiving plate piece 29 and fixed to the receiving plate piece 28 with a nail or an adhesive. Similarly, the adjacent base panel 30 is also supported by the plurality of support legs 25 to the receiving plate piece 29. It fixes and repeats for every base panel 30, and it constructs | assembles by laying the base panel 30 on the floor center part f2.

  As shown above, the illustrated floor foundation structure of the present invention, on the floor slab F, as shown in FIG. 1 (a), has a floor edge at the wall that needs to have a heat insulation structure that satisfies the legal heat insulation performance standard value. A first floor base X, which is formed by laying down the heat insulating panel 10 while adjusting the level with respect to the upper surface e of the joist E, is installed on f1, and then the base panel 30 is placed on the remaining floor central portion f2. After the second floor base Y is formed by adjusting and leveling the floor floor in the same manner, the floor finish plate P is installed next to the upper surfaces x and y of the first and second floor bases X and Y. Both floor bases X and Y having different structures are integrally connected by the connecting means A to construct one floor base B.

  Therefore, according to the illustrated floor foundation structure, the floor slab F has a level-adjusting mortar dango 5 on the floor edge f1 at the wall that needs to have a heat insulation structure that satisfies the legal heat insulation performance standard value. The first floor base X having high heat insulation performance formed by spreading the heat insulation panel 10 made of foamed resin is installed, and the base panel 30 is supported by the level adjustment support legs 25 and spread on the floor center part f2. Since the second floor base Y is installed and the floor bases X and Y having different structures are integrally connected by the connecting means A to construct one floor base B, separately, in the bare slab stage There is no need for time-consuming and time-consuming heat insulation reinforcement work, such as driving foamed plastic insulation under the floor slab F or spraying urethane foam on the wall W or floor slab F. work The body is simplified, it is possible to build a subfloor less expensive is also reduced manpower and the like.

  In the illustrated floor foundation structure, a floor finish plate P having a concave portion 6a and a convex portion 6b for joining at both ends in the short direction is used as a floor finish material for a Western-style room, and the first floor base X is placed on the floor slab F. After the second floor base Y is installed, the floor surface is finished by joining the floor finish plates P to the upper surfaces x and y with a concave and convex fit. Therefore, the connecting means A of the first example includes such a floor finish plate P in terms of configuration. When the floor finish plate P is joined on the first floor substrate X and the second floor substrate Y, the recess 6a is formed. The joint portion 6 into which the convex portion 6b fits is formed in a width size positioned on the crosspiece 20 of the heat insulation panel 10 of the first floor base X. Then, as shown in FIG. 1B, the connecting means A is used for joining the floor finishing plates P1 and P2 on the first floor base X and the second floor base Y when finishing the floor surface. For example, the convex portion 6b of the joint portion 6 is punched out with the floor nail 7 and fixed to the crosspiece 20, and then the concave portion 6a of the floor finishing plate P2 is fitted into the convex portion 6b of the floor finishing plate P1 to lower the first floor. The ground X and the second floor base Y are integrally connected to form one floor base B.

  Therefore, according to the connecting means A of the first example, the joint portion 6 where the concave portion 6a and the convex portion 6b are fitted is positioned on the pier 20 of the heat insulating panel 10, and the first floor foundation X and the second underfloor are located. The first and first structures are different from each other in a state where the joint portion j of both floor bases X and Y is straddled by the single floor finish plate P2 on the second floor base Y. Since the two floor foundations X and Y are joined, the difference in physical properties between the two floor foundations X and Y is absorbed, and the first floor foundation X and the second floor foundation Y are integrally connected to each other. The ground B can be constructed.

  As shown in the figure, the connecting means A of the first example has a concave portion 6a and a convex portion 6b when the floor finish plates P1 and P2 are joined on the first floor base X and the second floor base Y. The joint portion 6 to be fitted is positioned on the pier 20 provided near the second floor base Y of the heat insulating panel 10, and for example, the convex portion 6 b of the joint portion 6 is punched with the floor nail 7 and fixed to the pier 20. It is desirable. Thus, the connection strength can be increased by bringing the nail driving position at the joint 6 close to the joint portion j between the first floor base X and the second floor base Y.

  By the way, in the present invention, instead of the connecting means A of the first example described above, a second example of connecting means A ′ having the structure shown in FIG. 6 is provided, and the first structure having a structure different depending on the connecting means A ′. It is also possible to construct one floor base B by integrally connecting the floor base X and the second floor base Y.

  The connection means A ′ of the second example includes a connection plate 35 made of a single particle board, and the connection plate 35 is connected to the upper surface x of the heat insulation panel 10 of the first floor base X and the base of the second floor base Y. The first floor base X and the second floor base Y are integrally connected by being placed over the upper surface y of the panel 30 and fixed with a nail or an adhesive. The connecting plate 35 is not limited to a particle board, and various types of plywood can be used. In the floor base B of the present invention, the floor finishing plate P is overlapped on the connecting plate 35 as a floor finishing material for a Western-style room and fixed with nails or an adhesive to finish the floor surface.

  Therefore, according to the connection means A ′ of the second example, the single connection plate 35 is overlapped on the upper surface x of the heat insulation panel 10 of the first floor base X and the upper surface y of the base panel 30 of the second floor base Y. By fixing, the first floor base X and the second floor base Y having different structures in a state where the joint portion 35 straddles the joint portion j between the first floor base X and the second floor base Y. Therefore, the connection strength can be increased accordingly, and the difference in physical properties between the floor foundations X and Y can be absorbed and the connection can be made more integrally.

  Further, according to the connecting means A ′ of the second example, instead of nailing and fixing the floor finish plate directly to the shallow wood 20 of the heat insulation panel 10, as shown in FIG. Since the first floor base X and the second floor base Y are connected by overlaying and connecting the connecting plate 35 on 30, the floor surface can be finished by placing a floor finishing material on the connecting plate 35. Therefore, it is possible not only to lay a floor finish plate P of a Western-style floor finish material on the connecting plate 35, but also to lay a tatami mat 40 as a Japanese-style floor finish material as shown in FIG. Can also be finished. As a result, the present invention can be applied not only to Western-style rooms but also to Japanese-style floor foundations.

  Next, in the present invention, instead of the above-mentioned connecting means A and A ', a third example connecting means A "having the structure shown in FIG. 8 is provided, and the first underfloor having a different structure depends on the connecting means A". It is also possible to construct one floor base B by integrally connecting the ground X and the second floor base Y.

  The connecting means A ″ of the third example includes a joining plate 45 made of particle board and a plurality of joining bundles 50. The joining plate 45 may be a plate material having the same thickness as the base panel 30, and is not limited to the particle board. It is also possible to use various kinds of plywood, etc. The connection bundle 50 is made of wood, and is assembled by attaching a support plate piece 53 to each upper end of a column 52 standing on a base 51 so that the level can be adjusted. 50, the pedestal 51 may be individually in the form of a block piece as shown in the drawing, or may be formed by using a long object such as one long rafter on the side. Since the piece 53 does not know where the boundary of the upper joining plate 45 comes, it is desirable to form the piece 53 using a long object such as one long rafter as shown in FIG. And the connecting bundle 5 in the illustrated example It has become the height and gradients or disconnect cut strut 52 and the support plate piece 53 to be level adjusted fine tuning to.

  Accordingly, the connecting means A ″ of the third example adjusts the level of the support plate 53 and fixes each connection bundle 50 upright on the floor slab F between the heat insulating panel 10 and the support legs 25, and these connection bundles. On the support plate piece 53 of 50, the end portion 30a of the base panel 30 and the end portion 45a of the joining plate 45 to be fixed on the heat insulating panel 10 are placed facing each other and fixed, thereby fixing the first portion. The floor base X and the second floor base Y are integrally connected to form one floor base B.

  When the floor base B is constructed using the connecting means A ″ of the third example as described above, in detail, first, (1) the upper surface k of the support plate piece 53 and the upper surface e of the joist E have the same horizontal level.
