  FIG. 8 is an explanatory view of a conventional method for allocating an upper floor panel (upper floor base panel), and shows an example of allocating to a 2500 mm × 3340 mm rectangular room surrounded by walls A, B, C, and D. . In this case, the upper floor base panel is the most common particle board having a length of 1820 mm, a width of 600 mm, and a thickness of 20 (or 25) mm.

  In the allocation method shown in FIG. 8, the upper floor base panel 1 is allocated in six rows from the wall A side so that the long side of the upper floor base panel 1 is parallel to the wall A. In the figure, the one-dot chain line arrow indicates the long side direction and the attaching order of the upper floor base panel. The width of the first row and the sixth row is set to 420 mm. If the width of the first to fifth rows is set to 600 mm, the width of the sixth row becomes 240 mm, and the affixed upper floor base panel is unstable. This is because (600 mm + 240 mm) ÷ 2 = 420 mm, so that the upper floor base panel is stabilized with as wide a width as possible.

  As described above, when the upper floor base panel 1 is assigned by the conventional method, a large amount of remaining material is generated by cutting the upper floor base panel in the long side direction. The remaining material is an uncut portion having a width of 250 mm or less, which cannot be used as an upper floor base panel, and is mainly discarded as industrial waste. In FIG. 8, the hatched portion is the remaining material, the remaining material cut in the long side direction is 180 mm × 1820 mm, two 180 mm × 680 mm each, and the remaining material cut in the short side direction is 600 mm × 230 mm. It has occurred.

  The present invention minimizes the cutting in the long side direction in which a remaining material is likely to be generated, makes it possible to effectively use the upper floor panel, and prevents the upper floor panel from becoming industrial waste, thereby reducing the environmental load. It was made as an issue.

  In the method of allocating the upper floor panel of the double floor in which the upper floor panel is stuck on the floor support installed on the lower floor, the invention of claim 1 of the present application is the length of the upper floor panel from any one side of the room. Multi-row allocation so that the side is parallel to the one side, and the last row is allocated so that the long side of the upper floor panel is perpendicular to the one assigned so far, Panel assignment method.

  Since the last row is in a direction perpendicular to the previous allocation direction, only the last row may be cut in the long side direction of the upper floor panel, and the cutting length may be the width of the last row. Therefore, the cutting of the upper floor panel in the long side direction may be extremely short, and the generation of the remaining material can be minimized.

  Invention of Claim 2 of this application is the allocation method of Claim 1, The width | variety of the said last row | line is made wider than 200 mm, It is an upper floor sticking panel allocation method of the double floor characterized by the above-mentioned.

  It is desirable that the width of the last row be wider than 200 mm (more preferably 250 mm). When the width of the last row becomes small, the attached upper floor panel becomes unstable, which is not preferable. In such a case, the number of rows is reduced by one so that the width of the last row exceeds 200 mm (more preferably 250 mm). For example, if the width of the last sixth column is 240 mm, the number of columns is reduced by one to make the fifth column the last column, and the width of the fifth column is 240 mm + 600 mm (panel width). +20 mm (joint width) = 860 mm (see FIG. 1).

  Invention of Claim 3 of this application is the allocation method of Claim 1 or 2 WHEREIN: The said upper floor panel is an upper floor base panel, It is an upper floor sticking panel allocation method of the double floor characterized by the above-mentioned. The upper floor base panel is a structural material (that receives the load on the upper floor and transmits it to the floor support), and is generally a particle board or plywood.

  Invention of Claim 4 of this application is a double floor which has the floor support installed on the lower floor, and the upper floor formed on this floor support, Comprising: The panel for upper floors is allocated by the allocation method of Claims 1-3. It is a double floor characterized by that.

  In the present invention, since the cutting of the upper floor panel in the long side direction is minimized, the generation of remaining material is minimized, and the environmental burden can be reduced by preventing the upper floor panel from becoming industrial waste. it can.

  In the present invention, the double floor refers to the upper floor formed on the lower floor with a predetermined interval. The upper floor panel includes all rectangular panels to be attached to the upper floor, including the upper floor base panel. The upper floor base panel is a structural material (that receives the load on the upper floor and transmits it to the floor support), and is generally a particle board or plywood. The size may be a rectangle, but generally 455 mm × 1820 mm, 600 mm × 1820 mm, 910 mm × 1820 mm, and the thickness is generally 20 mm or 25 mm. FIG. 3 is the most common top floor base panel of 600 mm × 1820 mm. After the upper floor base panel is pasted, a discarded support plate portion (sound insulation sheet, plywood panel, etc.) can be further pasted, or any finishing material (flooring, tatami mat, carpet, etc.) can be provided.

  FIG. 7 shows an example in which a sound insulation sheet 11, a plywood panel 12 (discarded), and a flooring 13 as a finishing material are pasted on the upper floor base panel 1. The sound insulation sheet 11 and the plywood panel 12 in such a case also correspond to the upper floor panel in the present invention, and these allocation methods are also objects of the allocation method of the present invention. In addition, when a floor heating panel is provided on the upper floor base panel, an allocation method in a case where a discarded plywood panel is pasted around the floor heating panel is also an object of the present invention.

  The floor supporter only needs to be able to support the upper floor by floating from the lower floor. FIG. 4 shows an example of a single foot support 2, which includes a support plate portion 5, a receiving bracket 7, bolts 6, and legs 8. The support plate portion 5 is a wooden plate having a bolt hole, and a receiving bracket 7 is fixed to the lower surface. A bolt 6 is screwed into the female screw hole of the receiving bracket 7. The leg 8 is an anti-vibration rubber with the lower end of the bolt 6 inserted. There is a diametrical groove on the upper surface of the bolt 6, and the height can be adjusted by rotating with a screwdriver from above. FIG. 5 shows a multi-legged floor support 3, in which members having the same functions as those in FIG. As the floor support, various types such as a single foot floor support of FIG. 4, a multi-leg floor support of FIG. 4 and 5 show a plan view at the top and a cross-sectional view at the bottom.

  FIG. 1 is an explanatory plan view of a double floor according to the embodiment, and FIG. 2 is a sectional view taken along line XX in FIG. The living room in FIG. 1 is surrounded by walls A, B, C, and D, and has a size of 2500 mm × 3340 mm. The upper floor base panel 1 of 600 mm × 1820 mm in FIG. 3 is allocated to this room. A single-legged floor support 2 and a multiple-legged floor support 3 are appropriately arranged on the lower floor 9, and a joist 4 is provided along the wall. The corner joist 4 is a square bar (wood) and is supported by a bundle 10 (square bar) provided at appropriate intervals. The upper floor base panel 1 is affixed on these floor supports.

  It is arbitrary from which wall the upper floor base panel is assigned, but in this case, the assignment is made from the wall A. The upper floor base panel 1 is pasted so that its long side is parallel to the wall A. The arrow of the dashed-dotted line in the figure has shown the long side direction and order which sticks the upper floor base panel 1. FIG. However, the order is an example, and the present invention is not limited to this. The panel (a) is a so-called “true thing” that is not cut at all. The panel (b) is obtained by cutting the real object with a length of 680 mm in the short side direction. Panel (c) is the remainder after cutting panel (b). In this way, the first to fourth columns and panels (A) to (R) are pasted. There is no need to cut the upper floor base panel 1 in the long side direction until the fourth row is pasted. The reason why the joint width is 20 mm between the rows is to allow the height adjustment by rotating the bolts 6 of the support fittings 2 and 3 from above. Such joints are not necessary when allocating discarded plywood.

  As shown in FIG. 1, the width of the fifth row, which is the last row, is 860 mm, which is wider than 250 mm. If it is pasted up to the fifth row in the same way (with the long side of the panel parallel to the wall A), the width of the last sixth row will be as small as 240 mm, so reduce the number of rows. The last row is wide. In the fifth row which is the last row, that is, the row facing the wall C facing the wall A, the allocation direction of the upper floor base panel is changed by 90 °, and the long side of the upper floor base panel is perpendicular to the wall A. Put it in the direction. In this case, the upper floor base panel can be pasted without cutting at all in the long side direction. Even if it is necessary to cut the long side direction at the end of the last row (fifth row), the length to be cut may be the width of the last row (860 mm). Cutting in the side direction can be minimized, and the generation of remaining material can be significantly reduced.

  The present invention can be applied to a room whose schematic shape is a quadrilateral other than a square or rectangular room. FIG. 6 shows an example of allocation to trapezoidal rooms. This room consists of walls A, B, C and D, but the walls C are slanted. In such a case, it is preferable to allocate from the wall A facing the oblique wall C. The upper floor base panel 1 is pasted from the wall A so that the long side is parallel to this, and the last row (fifth row) is pasted in a direction perpendicular to the past. In this case, it is desirable to select the width of the last row so that the minimum width a of the fifth row is wider than 200 mm (more preferably 250 mm).

  The present invention is effective when applied to double floors such as apartment buildings and office buildings. The lower floor is mainly a concrete slab, but is not limited to this.
