[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 4 show one embodiment of a floor of the present invention, which is applied to a floor 18 of a balcony 11 that is provided on a building and protrudes to the outside. The balcony 11 is formed integrally with the building's framework, and as shown in Figures 1 and 2, has a floor 13 that protrudes from the building's exterior wall 12 toward the outdoors, a handrail front wall 14 that rises upward from the front end of the floor 13, and left and right handrail side walls 15 that rise upward from the left and right ends of the floor 13. As shown in Figure 1, the top surface (installation surface) 10 of the floor 13 has a water gradient that slopes downward toward the front, and a drain 16 is formed at the front end. A sweep window 17 is provided in the exterior wall 12, and people can enter and exit the balcony 11 through the sweep window 17.

[0008] As shown in Figures 1 to 3, the floor 18 comprises a plurality of auxiliary members 1,1,... arranged on the installation surface 10 in the depth direction at intervals in the width direction, a plurality of lower fittings 2,2,... attached to the upper surfaces of the auxiliary members 1,1,... at intervals in the longitudinal direction, a plurality of floor joists 3,3,... arranged in the depth direction at a position above the auxiliary members 1,1,... in the width direction at intervals, a plurality of upper fittings 4,4,... attached to the lower surfaces of the floor joists 3,3,... at intervals in the longitudinal direction, and a plurality of floorboards 5,5,... installed across the plurality of floor joists 3,3,... in a row in the width direction. 1, the upper surfaces of the floorboards 5, 5, ... are inclined so that the front side is lower, similar to the installation surface 10. Also, the installation height of the floorboards 5, 5, ... is adjusted by adjusting the height of the joists 3, 3, ... so that the upper surfaces of the floorboards 5, 5, ... are brought closer to the lower end of the bottom frame 19 of the French window 17.

[0009] The auxiliary material 1 is made of an extruded aluminum alloy material, and as shown in Figures 2 and 4, is formed with a generally rectangular cross section having an upper wall 20, a lower wall 21, and left and right side walls 22. On both the left and right sides of the upper wall 20, protrusions 23 for positioning the plate 6 of the lower metal fitting 2 are formed to protrude upward. A slit 24 is formed in the center of the upper wall 20 along the longitudinal direction. The auxiliary material 1 is simply placed on the installation surface 10, and is not adhered or otherwise attached.

[0010] 2 and 4, the lower fitting 2 has a rectangular plate 6 and a bolt 7 erected in the center of the plate 6, and the bolt 7 is rotatably supported by the plate 6. A cross hole 26 is formed in the upper end of the bolt 7 so that the bolt 7 can be rotated with a tool (a Phillips head screwdriver) 25 (see FIG. 5). The lower fitting 2 is placed on the upper surface of the auxiliary material 1 with the plate 6 positioned between the protrusions 23 of the auxiliary material 1, and is attached to the auxiliary material 1 by screwing it in place with screws 27 from above.

[0011] The joist 3 is made by turning the same aluminum alloy extrusion material as the auxiliary material 1 upside down, and as shown in Figures 1 and 5, is formed with a substantially rectangular cross section having an upper wall 28, a lower wall 29, and left and right side walls 40. On both the left and right sides of the lower wall 29, protrusions 30 are formed that protrude downward for positioning the plate 8 of the upper metal fitting 4. A slit 31 is formed in the center of the lower wall 29 along the longitudinal direction. A hole 32 is formed in the upper wall 28 above the bolt 7 of the lower metal fitting 2, as shown in Figure 5.

[0012] 5, the upper fitting 4 has a rectangular plate 8 and a cylindrical sleeve 33 suspended from the center of the plate 8. A female threaded hole 9 into which the bolt 7 of the lower fitting 2 screws into is formed in the lower part of the sleeve 33. The upper fitting 4 is attached to the joist 3 by abutting the plate 8 against the underside of the joist 3 with the plate 8 positioned between the protrusions 30 of the joist 3 and fastening it in place with screws 34 from below.

[0013] The floorboards 5 are made by extrusion molding synthetic resin mixed with wood powder, and as shown in Figures 2 and 4, are formed into plate shapes with a hollow portion 35, with engagement portions 36 protruding laterally from both edges. The floorboards 5 are arranged with gaps 37 in the frontage direction, and floorboard fixing brackets 38 arranged in the gaps 37 between the floorboards 5 are engaged with the engagement portions 36 and screwed to the joists 3 from above with screws 39, thereby pressing them downward and fixing them to the joists 3.

[0014] Next, a procedure for constructing the floor 18 will be described. First, as shown in Fig. 6-1(a), the reinforcing members 1, 1, ... are placed on the installation surface 10 in the depth direction at predetermined intervals in the frontage direction, and the lower fittings 2 are attached to the upper surface of each reinforcing member 1 at predetermined positions. Next, as shown in Figure 6-1(b), the upper fittings 4 are attached to the specified positions on the undersides of the floor joists 3, 3, .... When attaching the upper fittings 4, attach the upper fittings 4 to the floor joists 3 upside down (in the same orientation as the auxiliary materials), and then turn the surface with the upper fittings 4 attached downwards. Next, as shown in Fig. 6-2(c), the joists 3, 3, ... to which the upper fittings 4 are attached are placed above the auxiliary members 1, 1, ... in a direction intersecting with the auxiliary members 1, 1, ... (frontage direction), and the position of the female screw hole 9 of the upper fitting 4 is aligned with the position of the bolt 7 of the lower fitting 2, and then, as shown in Fig. 5, a tool 25 is inserted through a hole 32 formed in the upper surface of the joist 3, and the bolt 7 is rotated with the tool 25 to screw the bolt 7 into the female screw hole 9 of the upper fitting 4. Thereafter, the bolt 7 is rotated to adjust the height of the joist 3 so that it becomes a predetermined height according to the height of the bottom frame 19 of the sweep window 17. Next, as shown in FIG. 6-2(d), the floorboards 5, 5, ... are arranged in a line in the width direction on the joists 3, 3, ... and are attached one by one while being fixed with the floorboard fixing brackets 38, resulting in the state shown in FIG. 6-3(e).

[0015] As described above, the floor 18 comprises the auxiliary members 1,1,... arranged at intervals on the installation surface 10, the lower fittings 2,2,... attached to the upper surfaces of the auxiliary members 1,1,..., the joists 3,3,... arranged at intervals above the auxiliary members 1,1,... and intersecting with the auxiliary members 1,1,..., the upper fittings 4,4,... attached to the lower surfaces of the joists 3,3,..., and the floorboards 5,5,... attached to the upper surfaces of the joists 3,3,..., and the lower fittings 2 are attached to the upper surface of the auxiliary members 1,1,.... The upper fitting 4 has a plate 6 which is attached to the underside of the floor joist 3 and a female threaded hole 9 which screws into the bolt 7 of the lower fitting 2, and by screwing the bolt 7 of the lower fitting 2 into the female threaded hole 9 of the upper fitting 4 and rotating it, the height of the floor joist 3 can be adjusted freely (see Figure 1), and the height of the upper surface of the floorboard 5 can be adjusted appropriately to match the height of the bottom frame 19 of the French window 17, etc., making it easy to use. Furthermore, the main floor 18 is easy to construct because it is only necessary to simply place the auxiliary materials 1, 1, ... on the installation surface 10, and there is no need to glue any components onto the installation surface 10. Furthermore, by not using glue, the floor 18 can be easily renovated. The auxiliary material 1 has a protrusion 23 on its upper surface for positioning the plate 6 of the lower fitting 2, and the joist 3 has a protrusion 30 on its lower surface for positioning the plate 8 of the upper fitting 4, making it easy to attach the lower fitting 2 and the upper fitting 4, further improving workability. The auxiliary material 1 and the floor joists 3 are made by using materials with the same cross-sectional shape, but upside down, which reduces costs. Since the bolt 7 of the lower fitting 2 can be freely rotated by a tool 25 inserted into the floor joist 3 from above (see FIG. 5), the height of the floor joist 3 can be easily adjusted.

[0016] The present invention is not limited to the above-described embodiment. The materials and cross-sectional shapes of the auxiliary materials, joists, and floorboards can be changed as appropriate. The shapes of the lower and upper metal fittings can also be changed as appropriate. The present invention is not limited to being installed on balconies, but can be widely used as floors for various structures, such as terraces, garden rooms, and outdoor decks.
