[0005] (1) The floor material for solving the above problems includes a floor material body, a reinforcing member disposed in the floor material body, and a discomfort suppressing portion capable of suppressing discomfort. The floor material body has an upper plate and a lower plate located below the upper plate. The reinforcing member is disposed between the upper plate and the lower plate, and the discomfort suppressing portion is disposed in the floor material body. According to this configuration, the discomfort suppressing portion suppresses discomfort. Therefore, the occurrence of discomfort given by the floor material body to a person can be suppressed.

[0006] (2) In the floor material of (1) above, the floor material body has a plurality of partition walls that partition the space between the upper plate and the lower plate, the plurality of partition walls are arranged to be parallel to each other, and the reinforcing member is arranged in at least one of the plurality of spaces formed by the plurality of partition walls.

[0007] When walking on the floor, if the floor material sags, it may cause discomfort to people. According to the above configuration, the reinforcing member and the plurality of partition walls suppress the sagging of the floor material. Therefore, it is possible to suppress the occurrence of discomfort received by people walking on the floor material from the floor material.

[0008] (3) In the floor material of (2) above, the reinforcing member is configured to extend along the partition wall, has a hollow portion extending in the longitudinal direction of the reinforcing member, and a sound-absorbing material as the discomfort suppressing portion is arranged in the hollow portion.

[0009] When the reinforcing member has a hollow portion, if an object falls on the floor material, there is a possibility that the sound will resonate in the hollow portion. Also, in the case of a floor material placed outdoors where the reinforcing member of the floor material has a hollow portion, when rain or sleet falls, there is a possibility that the sound will resonate in the hollow portion when the rain or sleet hits the floor material. Since such sounds are not natural sounds, they may cause discomfort to people. According to the above configuration, the sound-absorbing material suppresses the resonance of sound within the floor material body. Therefore, it is possible to suppress the occurrence of discomfort caused by the sound generated when an object, rain, sleet, etc. hits the floor material.

[0010] (4) In the floor material of (2) above, the reinforcing member is configured to extend along the partition wall, has a hollow portion extending in the longitudinal direction of the reinforcing member, the reinforcing member has an outer peripheral surface on the side opposite to the inner peripheral surface that forms the hollow portion, and a buffer material as the discomfort suppressing portion is arranged on at least a part of the outer peripheral surface that contacts the floor material body.

[0011] When the flooring material is hard, the walking comfort may not be good. In this regard, according to the above configuration, by arranging the cushioning material between the flooring material main body and the reinforcing member, appropriate cushioning properties can be imparted to the flooring material. Therefore, the generation of discomfort received by a person walking on the flooring material can be suppressed.

[0012] (5) In any one of the flooring materials of the above (1) to the above (4), the reinforcing member is made of aluminum, wood, bamboo, or resin. According to this configuration, the flooring material can be made lighter compared to the case where the reinforcing member is made of iron.

[0013] (6) The building that solves the above problems is a building having a floor, and the floor includes any one of the flooring materials of the above (1) to the above (5). According to this configuration, the discomfort suppression part provided in the flooring material suppresses discomfort. Therefore, the generation of discomfort given by the flooring material main body to a person can be suppressed.

[0014] (7) In the building of the above (6), it further includes a floor frame, the floor frame includes a plurality of support members that support the flooring material, the plurality of support members are arranged at intervals of a predetermined length or more, and in a plan view, the flooring material is arranged such that the reinforcing member intersects the support member. According to this configuration, the support member intersects the reinforcing member of the flooring material in a plan view. Therefore, compared to the case where the support member is arranged parallel to the reinforcing member, the deflection of the flooring material when a load is applied can be reduced.

Effect of the Invention

[0015] According to the flooring material and the building of the present disclosure, the generation of discomfort can be suppressed.

The third side plate 23 constitutes a part of the recess 15C of the floor material body 15.

[0031] The recess 15C is constituted by the second side plate 22, the third side plate 23, and the lower plate 19. In the recess 15C, locking grooves 26 are provided on the surfaces of the second side plate 22 and the third side plate 23. A lid 27 for closing the recess 15C is provided in the recess 15C. The lid 27 extends along the longitudinal direction of the floor material body 15. The lid 27 has locking claws 28 that lock into the locking grooves 26. The lid 27 and the recess 15C are configured such that the upper surface 18C of the upper plate 18 and the upper surface 27A of the lid 27 are continuous when the locking claws 28 are locked into the locking grooves 26. The recess 15C is configured as a portion for driving screws to fix the floor material 1 to the floor frame 5. After screws are driven into the recess 15C to fix the floor material 1 to the floor frame 5, the lid 27 is attached to the recess 15C.

[0032] The floor material body 15 has a plurality of partition walls 25 that partition the space S between the upper plate 18 and the lower plate 19. The plurality of partition walls 25 are arranged to be parallel to each other. The partition walls 25 extend along the longitudinal direction of the floor material body 15. In this embodiment, the first space SB is partitioned by two partition walls 25. Also, the second space SC is partitioned by three partition walls 25.

[0033] The reinforcing member 16 is disposed between the upper plate 18 and the lower plate 19. The reinforcing member 16 is disposed in at least one of the plurality of spaces formed by the plurality of partition walls 25. The plurality of spaces formed by the plurality of partition walls 25 include the space between two partition walls 25, the space between the partition wall 25 and the first side plate 21, the space between the partition wall 25 and the second side plate 22, and the space between the partition wall 25 and the third side plate 23. The reinforcing member 16 is configured to extend along the partition wall 25. Therefore, in the present embodiment, the reinforcing member 16 extends along the longitudinal direction of the floor material body 15. The reinforcing member 16 has a hollow portion 29 extending in the longitudinal direction of the reinforcing member 16. The reinforcing member 16 is formed in a cylindrical shape. Further, the reinforcing member 16 is made of aluminum, wood, bamboo, or resin. In the present embodiment, the reinforcing member 16 is made of aluminum. In one example, the diameter of the reinforcing member 16 is 31 mm or less.

[0034] <Discomfort suppression part> The discomfort suppression part 17 is disposed in the floor material body 15. In the present embodiment, the discomfort suppression part 17 includes a sound absorption material 30 and a cushioning material 31. The sound absorption material 30 is disposed in the floor material body 15 as follows. The sound absorption material 30 as the discomfort suppression part 17 is disposed in the hollow portion 29 of the reinforcing member 16. Examples of the sound absorption material 30 include styrofoam, sponge, glass wool, and the like. In the present embodiment, the sound absorption material 30 is styrofoam. Further, in the present embodiment, the sound absorption material 30 is filled in the hollow portion 29.

[0035] The cushioning material 31 is disposed in the floor material body 15 as follows. The reinforcing member 16 has an outer peripheral surface 32 on the side opposite to the inner peripheral surface constituting the hollow portion 29. On the outer peripheral surface 32, the cushioning material 31 as the discomfort suppression part 17 is disposed on at least a part that contacts the floor material body 15. In the present embodiment, the cushioning material 31 is constituted by an elastic sheet-like member. The cushioning material 31 is attached to the entire circumference of the outer peripheral surface 32 of the reinforcing member 16. Examples of the cushioning material 31 include styrofoam, polyethylene sheet, sponge, rubber sheet, and the like. In the present embodiment, the cushioning material 31 is a polyethylene sheet.

[0036] The cushioning material 31 is formed such that at least a part of the cushioning material 31 contacts the upper plate 18 in a state where the cushioning material 31 is attached to the reinforcing member 16.

[0037] In another example, a plurality of cushioning materials 31 are arranged on the outer peripheral surface 32 of the reinforcing member 16. The plurality of cushioning materials 31 are attached to the outer peripheral surface 32 at a predetermined interval from each other. The cushioning material 31 may also be attached to a portion of the outer peripheral surface 32 that does not contact the upper plate 18 and the lower plate 19. Each of the plurality of cushioning materials 31 extends along the longitudinal direction of the reinforcing member 16.

[0038] The operation of this embodiment will be described. The sound-absorbing material 30 and the cushioning material 31 as the discomfort suppression part 17 are arranged in the floor material body 15. The sound-absorbing material 30 is arranged in the hollow part 29 of the reinforcing member 16. The cushioning material 31 is arranged on at least a part of the outer peripheral surface 32 of the reinforcing member 16 that contacts the floor material body 15.

[0039] When a person walks on the floor material, the person may feel discomfort due to the sound resonance in the floor material or the poor feeling underfoot. Also, when an object drops or rain or sleet hits the floor material, the person may feel discomfort due to the sound. According to this embodiment, the sound-absorbing material 30 suppresses the sound resonance in the floor material 1. The cushioning material 31 provides a moderate feeling underfoot. Therefore, the generation of discomfort received by the person can be suppressed.

[0040] The effects of this embodiment will be described. (1) The floor material 1 includes a floor material body 15, a reinforcing member 16 arranged in the floor material body 15, and a discomfort suppression part 17 that can suppress discomfort. The floor material body 15 has an upper plate 18 and a lower plate 19 located below the upper plate 18. The reinforcing member 16 is arranged between the upper plate 18 and the lower plate 19. The discomfort suppression part 17 is arranged in the floor material body 15. According to this configuration, the discomfort suppression part 17 suppresses discomfort. Therefore, the generation of discomfort given by the floor material body 15 to the person can be suppressed.

[0041] (2) The flooring body 15 has a plurality of partition walls 25 that partition the space S between the upper plate 18 and the lower plate 19. The plurality of partition walls 25 are arranged to be parallel to each other. The reinforcing member 16 is disposed in at least one of the plurality of spaces formed by the plurality of partition walls 25. When walking on the floor, if the flooring sags, it may cause discomfort to people. According to the above configuration, the reinforcing member 16 and the plurality of partition walls 25 suppress the sagging of the flooring 1. Therefore, the generation of discomfort received by a person walking on the flooring 1 from the flooring 1 can be suppressed.

[0042] (3) The reinforcing member 16 is configured to extend along the partition wall 25. The reinforcing member 16 has a hollow portion 29 that extends in the longitudinal direction of the reinforcing member 16. An acoustic absorption material 30 as a discomfort suppression portion 17 is disposed in the hollow portion 29.

[0043] When the reinforcing member has a hollow portion, if an object falls on the flooring, there is a possibility that a sound will resonate in the hollow portion. Also, in the case of a flooring placed outdoors, when the reinforcing member of the flooring has a hollow portion, when rain or sleet falls, there is a possibility that a sound will resonate in the hollow portion when the rain or sleet hits the flooring. Since such sounds are not natural sounds, they may cause discomfort to people. According to the above configuration, the acoustic absorption material 30 suppresses the resonance of sound in the flooring body 15. Therefore, the generation of discomfort caused by the sound generated when an object, rain, sleet, etc. hits the flooring 1 can be suppressed.

[0044] (4) The reinforcing member 16 is configured to extend along the partition wall 25. The reinforcing member 16 has a hollow portion 29 that extends in the longitudinal direction of the reinforcing member 16. The reinforcing member 16 has an outer peripheral surface 32 on the side opposite to the inner peripheral surface that forms the hollow portion 29. On the outer peripheral surface 32, a cushioning material 31 is disposed on at least a part that contacts the flooring body 15.

[0045] When the flooring is hard, the walking comfort may not be good. In this regard, according to the above configuration, by disposing the cushioning material 31 between the flooring body 15 and the reinforcing member 16, appropriate cushioning properties can be imparted to the flooring 1. Therefore, the generation of discomfort received by a person walking on the flooring 1 from the flooring 1 can be suppressed.

[0046] (5) The reinforcing member 16 is made of aluminum, wood, bamboo, or resin. According to this configuration, the floor material 1 can be made lighter than when the reinforcing member 16 is made of iron.

[0047] (6) The building 2 includes a floor 4. The floor 4 includes the floor material 1. According to this configuration, the discomfort suppression part 17 provided in the floor material 1 suppresses discomfort. Therefore, the generation of discomfort given by the floor material main body 15 to people can be suppressed.

[0048] (7) The building 2 further includes a floor frame 5. The floor frame 5 includes a plurality of support members 8 that support the floor material 1. The plurality of support members 8 are arranged at intervals of a predetermined length or more. In plan view, the floor material 1 is arranged such that the reinforcing member 16 intersects the support member 8. According to this configuration, the support member 8 intersects the reinforcing member 16 of the floor material 1 in plan view. Therefore, compared with the case where the support member 8 is arranged parallel to the reinforcing member 16, the deflection of the floor material 1 when a load is applied can be reduced.

[0049] <Modification Example> The above embodiment is an exemplification of the forms that the floor material 1 and the building 2 can take, and is not intended to limit such forms. The floor material 1 and the building 2 can take forms different from those exemplified in the above embodiment. An example thereof is a form in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a new configuration is added to the embodiment. An example of a modification example of the embodiment is shown below.

[0050] · As shown in FIG. 6, the cushioning material 31 may be attached only to the outer peripheral surface 32 above the reinforcing member 16. The cushioning material 31 may be configured to contact the upper plate 18 on the outer peripheral surface 32 above the reinforcing member 16. Specifically, the thickness is adjusted by stacking a plurality of cushioning materials 31. Alternatively, the cushioning material 31 is filled between the upper plate 18 and the outer peripheral surface 32 above the reinforcing member 16. By disposing the cushioning material 31 between the floor material body 15 and the reinforcing member 16, appropriate cushioning properties can be imparted to the floor material 1. Therefore, the generation of discomfort received by a person walking on the floor material 1 from the floor material 1 can be suppressed.

[0051] · As shown in FIG. 7, the shape of the reinforcing member 16 is not limited to a cylindrical shape. The cross section of the reinforcing member 16 in this modification is a rectangular cross section. In the rectangular cross section, the corners of the reinforcing member 16 are chamfered into curved surfaces. For example, the reinforcing member 16 is a square pipe. Also, the entire outer peripheral surface 32 of the reinforcing member 16 may be covered by one cushioning material 31.

[0052] · As shown in FIG. 8, the discomfort suppressing portion 17 may be disposed only in the main part within the floor material body 15. Also, in the floor material 1, in a portion where people do not walk much, the discomfort suppressing portion 17 may not be disposed in the floor material body 15 thereunder. For example, in the floor 4, the portion including the disengaged opening 18B is adjacent to a place where people enter and exit, such as the sweeping window 14. The vicinity of this opening 18B is a portion where people walk. Therefore, the sound absorbing material 30 and the cushioning material 31 are disposed in the second space SC adjacent to the opening 18B. Also, in the floor 4, the portion including the disengaged claw portion 18A is adjacent to the outer wall 7 of the balcony 6. The vicinity of this claw portion 18A is a portion where people do not walk much. Therefore, only the reinforcing member 16 is disposed in the first space SB adjacent to the claw portion 18A. In this way, the discomfort suppressing portion 17 may be disposed according to the arrangement state of the floor material 1. Thereby, the floor material 1 can be made lighter.

[0053] · The sound absorbing material 30 does not have to be filled in the hollow portion 29. The sound absorbing material 30 may be disposed in a part of the hollow portion 29. Thereby, the cost of the floor material 1 can be suppressed.
