[0027] In a plan view, the floor member 31 is positioned between the first horizontal member 21 and the second horizontal member 22. In a plan view, the floor member 31 is positioned between the third horizontal member 23 and the fourth horizontal member 24. The floor member 31 is formed of, for example, ALC (Autoclaved Lightweight Aerated Concrete). The floor member 31 may be formed of a material other than ALC.

[0028] The floor member 31 is divided into a plurality of small blocks 32. The floor member 31 is, for example, divided into a plurality of small blocks 32 in advance. Each small block 32 is assembled into one and transported to the construction site. In this embodiment, the length of one side of each small block 32 in plan view is greater than the diameter of the pipe. The length of one side of each small block 32 in plan view is, for example, greater than 50 mm and 100 mm or less. In this embodiment, each small block 32 is square in plan view.

[0029] The support member 40 supports the floor member 31 below the floor member 31. The support member 40 has a support member body 41 and a fixing part 42. In a plan view, the support member body 41 is positioned between the first horizontal member 21 and the second horizontal member 22. In a plan view, the support member body 41 and the fixing part 42 are positioned between the third horizontal member 23 and the fourth horizontal member 24. The support member body 41 is, for example, a rectangular plate. The support member 40 is formed from a metal material.

[0030] As shown in Figures 3 and 4, the fixing portion 42 is provided on the support member body 41. The fixing portion 42 fixes the support member 40 to the first horizontal member 21 and the second horizontal member 22. The fixing portion 42 is provided on one side of the support member body 41 corresponding to the first horizontal member 21 and on one side of the support member body 41 corresponding to the second horizontal member 22. At least one fixing portion 42 is provided on the side of the support member body 41 corresponding to the first horizontal member 21. At least one fixing portion 42 is provided on the side of the support member body 41 corresponding to the second horizontal member 22. In one example, four fixing portions 42 are provided on the side of the support member body 41 corresponding to the first horizontal member 21 and on the side of the support member body 41 corresponding to the second horizontal member 22. Part of the fixing portion 42 is positioned above the first flange 20B of the first horizontal member 21 and the second horizontal member 22, respectively.

[0031] The fixing portion 42 has a first through hole 42A. A first fastening member 42B is inserted into the first through hole 42A. The support member 40 is fastened to the first horizontal member 21 and the second horizontal member 22 by the first fastening member 42B. The first fastening member 42B includes, for example, a bolt 42C. Fastening holes 20D are provided in the first flanges 20B of the first horizontal member 21 and the second horizontal member 22. Nuts 42D that engage with the bolts 42C are provided on the lower surfaces of the first flanges 20B of the first horizontal member 21 and the second horizontal member 22 by welding or the like. The nuts 42D are provided at positions corresponding to the respective fastening holes 20D of the first horizontal member 21 and the second horizontal member 22. The bolt 42C is inserted from above the first horizontal member 21 and the second horizontal member 22 and engages with the nut 42D to fasten the support member 40 to the first horizontal member 21 and the second horizontal member 22. The first through hole 42A and the fastening hole 20D may be provided with female threads that engage with the bolt 42C. In this case, the nut 42D may be omitted.

[0032] As shown in Figures 3 and 4, the support member 40 has a first arrangement section 43 in which the small block 32 is arranged. The first arrangement section 43 is arranged alongside the support member body 41. The first arrangement section 43 has a small block support section 44 and a first pipe arrangement section 45. The small block support section 44 is arranged to surround the first pipe arrangement section 45. The small block support section 44 is located below the small block 32 and supports the small block 32. The small block support section 44 is configured to follow the periphery of the lower surface 32B of the small block 32. The first pipe arrangement section 45 includes a first hole 45A. Pipes for water, gas pipes, and ventilation pipes are arranged in the first hole 45A. In this embodiment, the first hole 45A is square. One side of the first hole 45A is, for example, 50 mm or more and less than 100 mm. In this embodiment, the diameter of the piping is smaller than the length of one side of the first hole 45A.

[0033] As shown in Figures 2 and 3, the floor structure 30 further comprises an engaging member 50. The engaging member 50 is positioned above the floor member 31 and engages with the floor member 31. The engaging member 50 has an engaging member body 51 and a fastening portion 52 provided on the engaging member body 51. The engaging member body 51 is positioned opposite the support member 40 so as to sandwich the floor member 31 together with the support member 40. The engaging member 50 is, for example, a rectangular plate. The engaging member 50 is made of a metal material.

[0034] At least one fastening portion 52 is provided on each side of the engaging member body 51 that is on the third horizontal member 23 side and the fourth horizontal member 24 side. In one example, two fastening portions 52 are provided on one side of the engaging member body 51 that is on the third horizontal member 23 side and two on the side of the engaging member body 51 that is on the fourth horizontal member 24 side.

[0035] The fastening portion 52 has a second through-hole 52A as shown in Figure 7. A second fastening member 52B is inserted into the second through-hole 52A. The engaging member 50 is fastened to the support member 40 by the second fastening member 52B. In the support member body 41, a third through-hole 43E corresponding to the second through-hole 52A is provided on one side corresponding to the third horizontal member 23 and the fourth horizontal member 24. The second fastening member 52B includes, for example, a bolt 52C. The bolt 52C is inserted into the second through-hole 52A and the third through-hole 43E. A nut that engages with the bolt 52C is provided on the lower surface of the portion of the support member body 41 corresponding to the third through-hole 43E by welding or the like. When the bolt 52C is inserted into the second through-hole 52A and the third through-hole 43E, it engages with the nut on the lower side of the third through-hole 43E. With the bolt 52C engaged with the lower nut of the third through hole 43E, the engaging member 50 is fastened to the support member 40 by attaching the nut 52D that engages with the bolt 52C from above.

[0036] The engaging member 50 has a second placement section 53 on which the small block 32 is arranged. The second placement section 53 is arranged alongside the engaging member 50. In the vertical direction, the second placement section 53 is provided at a position on the engaging member 50 that corresponds to the first placement section 43 of the support member 40. The second placement section 53 has a small block engaging section 54 and a second pipe placement section 55. The small block engaging section 54 is arranged to surround the second pipe placement section 55. The small block engaging section 54 is located above the small block 32. The small block engaging section 54 is configured to follow the periphery of the upper surface of the small block 32. The second pipe placement section 55 includes a second hole 55A. Pipes for water, gas, and ventilation are arranged in the second hole 55A. In this embodiment, the second hole 55A is square. One side of the second hole 55A is, for example, 50 mm or more and less than 100 mm. In this embodiment, the diameter of the pipe is smaller than the length of one side of the second hole 55A.

[0037] <Procedure for arranging floor components 31> Referring to Figures 1 to 7, the procedure for arranging the floor members 31 will be described. As shown in Figure 5, the support members 40 are pre-attached to the first horizontal members 21 and the second horizontal members 22 by fixing parts 42. The floor members 31 are placed on the support members 40 from above. Each small block 32 is aligned so that it is placed in each first arrangement part 43.

[0038] As shown in Figures 1, 3, 4, and 6, the small blocks 32 placed in each first placement section 43 are removed according to the size of the pipe. In one example, a first pipe 3 corresponding to the size of one small block 32 and a second pipe 4 corresponding to four small blocks 32 are placed in the pipe space 2. If pipes corresponding to two or more small blocks 32 are to be placed in the pipe space 2, after the small blocks 32 are removed, a portion of the small block support portion 44 of the first placement section 43 is cut at the work site. By cutting a portion of the small block support portion 44 of the first placement section 43, even pipes larger than the size corresponding to one small block 32 can be placed in the pipe space 2.

[0039] As shown in Figures 2 and 7, after the small blocks 32 are removed according to the size of the piping, the engaging member 50 is attached from above the floor member 31. A portion of the small block engaging portion 54 of the second placement portion 53 is cut to correspond to a portion of the small block support portion 44 of the first placement portion 43, which has been cut to match the size of the piping. The cutting of the portion of the small block engaging portion 54 is performed, for example, on-site to match the size of the piping. The second placement portion 53 of the engaging member 50 is aligned to correspond to each small block 32. The placement of the floor member 31 is completed when the engaging member 50 is fastened to the support member 40 by the second fastening member 52B.

[0040] Figures 1 and 4 show an example in which, after the placement of the floor member 31 is complete, human activity spaces are placed on both sides of the pipe space 2. After the floor member 31 is placed, a finishing member 5 is provided between the first floor section 12 and the second floor section 13. The finishing member 5 includes, for example, insulation material and mortar.

[0041] <Operation of the First Embodiment> Conventionally, holes were drilled into the flooring material to allow piping to pass through the second floor section 13. In this case, drilling the holes was time-consuming. In this embodiment, however, the floor member 31, which is divided into a plurality of small blocks 32, is arranged between the first horizontal member 21 and the second horizontal member 22, and between the third horizontal member 23 and the fourth horizontal member 24. The plurality of small blocks 32 are supported by support members 40. Therefore, when passing piping through the second floor section 13, it is only necessary to remove the small blocks 32, improving work efficiency.

[0042] <Effects of the First Embodiment> The effects of the first embodiment will be explained. (1-1) The floor structure 30 of building 1 comprises a first horizontal member 21, a second horizontal member 22 adjacent to the first horizontal member 21 at a distance from it, a floor member 31 positioned between the first horizontal member 21 and the second horizontal member 22 and divided into a plurality of small blocks 32, and a support member 40 that supports the floor member 31 below the floor member 31. The support member 40 has a first arrangement section 43 on which the small blocks 32 are arranged.

[0043] With this configuration, the support member 40 has a first placement section 43 where the small blocks 32 are arranged, making it easy to position the floor member 31. Therefore, the floor structure 30 can suppress a decrease in work efficiency during piping work.

[0044] Furthermore, this configuration offers greater flexibility in piping placement compared to the case where holes are made in the flooring material. This point will be explained below. When holes are made in the flooring material, there is a risk of cracking or fissures occurring in the flooring material. In particular, concrete flooring materials are prone to cracking depending on where the holes are made. For this reason, when holes are made in the flooring material, standards are set for the distance from the edge of the flooring material, the number of holes to be made in the flooring material, and the size of the holes. Due to these standards, there are restrictions on the position, number, and size of holes to be made in the flooring material. In this embodiment, however, the floor member 31 is divided into a plurality of small blocks 32. Therefore, in order to pass the piping through the floor member 31, there is no need to make holes, and the piping can be passed through by removing the small blocks 32. Because there is no processing of the flooring material in this way, there are fewer restrictions on the position, number, and size of holes in the floor member 31 compared to the case where holes are made in the flooring material.

[0045] (1-2) The support member 40 comprises a support member body 41 and a fixing part 42 provided on the support member body 41 and fixing the support member 40 to the first horizontal member 21 and the second horizontal member 22.

[0046] With this configuration, the support member 40 can be fixed to the first horizontal member 21 and the second horizontal member 22 by the fixing part 42, allowing the small block 32 to be suitably positioned between the first horizontal member 21 and the second horizontal member 22.

[0047] (1-3) The fixing portion 42 has a first through hole 42A. The support member 40 is fastened to the first horizontal member 21 and the second horizontal member 22 by a first fastening member 42B inserted into the first through hole 42A.

[0048] With this configuration, the support member 40 can be suitably fixed to the first horizontal member 21 and the second horizontal member 22 by the first fastening member 42B.

[0049] (1-4) The system further comprises an engaging member 50 positioned above the floor member 31 and engaging with the floor member 31. The engaging member 50 has a second positioning portion 53 on which the small block 32 is positioned.

[0050] With this configuration, each small block 32 can be positioned appropriately by arranging it between the first placement portion 43 of the support member 40 and the second placement portion 53 of the engaging member 50 in the vertical direction.

[0051] (1-5) The engaging member 50 has an engaging member body 51 and a fastening portion 52 provided on the engaging member body 51. The fastening portion 52 has a second through hole 52A. The engaging member 50 is fastened to the support member 40 by a second fastening member 52B inserted into the second through hole 52A.

[0052] With this configuration, by fastening the engaging member 50 to the support member 40, it is possible to suppress the displacement of each small block 32.

[0053] <Second Embodiment> The floor structure 30 of the second embodiment will be described with reference to Figures 2, 3, and 8 to 10. In this embodiment, components common to the first embodiment are denoted by the same reference numerals as in the first embodiment, and the description of redundant components is omitted.

[0054] As shown in Figures 2, 3, and 8, the support member 40 has a partition 46 positioned between adjacent small blocks 32. The partition 46 is positioned between adjacent first arrangement sections 43. The partition 46 extends upward from the small block support section 44. The small block support section 44 extends from the lower end 46F of the partition 46 toward the other opposing partition 46. The lower end 46F of the partition 46 is connected to the small block support section 44. The first pipe arrangement section 45 is positioned between adjacent partition sections 46.

[0055] A housing section 47 is formed by a partition section 46, a small block support section 44, and a first pipe arrangement section 45. The housing section 47 includes a first arrangement section 43. The partition section 46 has a first partition section 46A and a second partition section 46B that face each other. The partition section 46 has a third partition section 46C and a fourth partition section 46D that intersect with the first partition section 46A and the second partition section 46B and face each other. In this embodiment, the first partition section 46A extends parallel to the first horizontal member 21. The second partition section 46B extends parallel to the second horizontal member 22. The third partition section 46C extends parallel to the third horizontal member 23. The fourth partition section 46D extends parallel to the fourth horizontal member 24. The storage section 47 is partitioned, for example, by a first partition section 46A, a second partition section 46B, a third partition section 46C, and a fourth partition section 46D.

[0056] As shown in Figures 2, 3, and 8 to 10, the small block 32 has a small block body 33 and a contact portion 34 extending downward from the small block body 33. The partition portion 46 is provided along the side surface 32A of the small block 32. The small block support portion 44 is provided along the lower surface 32B of the small block 32. In this embodiment, the partition portion 46 is provided along the side surface 32A of the contact portion 34. The partition portion 46 is provided along the lower surface 32B of the contact portion 34. The contact portion 34 is positioned between adjacent partition portions 46. The contact portion 34 is positioned in the first arrangement portion 43 so as to block the first pipe arrangement portion 45.

[0057] The contact portion 34 has a first width X1 and a second width X2. The first width X1 is the width of the contact portion 34 in the direction along the first partition portion 46A and the second partition portion 46B. The second width X2 is the width of the contact portion 34 in the direction along the third partition portion 46C and the fourth partition portion 46D. The first width X1 of the contact portion 34 is smaller than the distance D1 from the first partition portion 46A to the second partition portion 46B. The second width X2 of the contact portion 34 is smaller than the distance D2 from the third partition portion 46C to the fourth partition portion 46D.

[0058] The small block body 33 has a third width X3 and a fourth width X4. The third width X3 is the width of the small block body 33 in the direction along the first partition portion 46A and the second partition portion 46B. The fourth width X4 is the width of the small block body 33 in the direction along the third partition portion 46C and the fourth partition portion 46D. The third width X3 of the small block body 33 is greater than the first width X1 of the contact portion 34. The fourth width X4 of the small block body 33 is greater than the second width X2 of the contact portion 34.

[0059] The lower surface 32B of the small block 32 is in contact with the small block support portion 44. Specifically, the lower surface 32B of the contact portion 34 is in contact with the small block support portion 44. The height H of the contact portion 34 is greater than the distance D3 from the upper end 46E of the partition portion 46 to the upper surface 44A of the small block support portion 44.

[0060] <Operation of the second embodiment> The first width X1 of the contact portion 34 is smaller than the distance D1 from the first partition portion 46A to the second partition portion 46B, and the second width X2 of the contact portion 34 is smaller than the distance D2 from the third partition portion 46C to the fourth partition portion 46D. Therefore, the contact portion 34 is easily accommodated in the housing portion 47.

[0061] The height H of the contact portion 34 is greater than the distance D3 from the upper end 46E of the partition portion 46 to the upper surface 44A of the small block support portion 44. Therefore, when the contact portion 34 is housed in the housing portion 47, the distance between adjacent small block bodies 33 becomes smaller. Consequently, large gaps are less likely to occur between adjacent small block bodies 33.

[0062] <Effects of the second embodiment> The effects of the second embodiment will be explained. (2-1) The support member 40 has a partition portion 46 which is placed between adjacent small blocks 32. The partition portion 46 is placed between adjacent first placement portions 43.
