[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to flooring and construction. [Background technology]

[0002] There are known technologies relating to flooring materials that constitute the floors of buildings. For example, the flooring material described in Patent Document 1 includes a plate-shaped flooring body and a plurality of cavities formed within the flooring body along the longitudinal direction of the flooring body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-166306 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when walking on a floor made of flooring materials, discomfort may occur. From the viewpoint of suppressing discomfort caused by flooring materials, there is room for improvement in flooring materials and buildings. [Means for solving the problem]

[0005] (1) A flooring material that solves the above problem includes a flooring body, a reinforcing member disposed within the flooring body, and a discomfort suppression unit that can suppress discomfort. The flooring 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 suppression unit is disposed within the flooring body. With this configuration, the discomfort suppression unit suppresses discomfort. Therefore, the discomfort caused by the flooring body can be suppressed.

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

[0007] If the flooring sags when people walk on it, it can cause discomfort. With the above-described configuration, the reinforcing member and the multiple partition walls prevent the flooring from sagging. This reduces discomfort experienced by people walking on the flooring.

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

[0009] If the reinforcing member has a hollow portion, there is a risk that if an object falls on the flooring material, sound will resonate in the hollow portion. Furthermore, if the reinforcing member of a flooring material placed outdoors has a hollow portion, there is a risk that if rainwater or hail falls, the rainwater or hail will hit the flooring material and cause sound to resonate in the hollow portion. Because such sounds are not natural sounds, they may cause discomfort to people. According to the above configuration, the sound-absorbing material suppresses sound from resonating within the flooring material itself. This reduces the discomfort caused by sounds generated when objects, rainwater, hail, etc. hit the flooring material.

[0010] (4) In the flooring material of (2) above, the reinforcing member is configured to extend along the partition wall and has a hollow portion extending in the longitudinal direction of the reinforcing member, the reinforcing member has an outer peripheral surface opposite to the inner peripheral surface that forms the hollow portion, and a cushioning material is arranged as the discomfort suppression portion on at least a portion of the outer peripheral surface that comes into contact with the flooring body.

[0011] If the flooring is hard, it may be uncomfortable to walk on. In this regard, with the above-described configuration, the buffer material is placed between the flooring body and the reinforcing member, which gives the flooring an appropriate cushioning effect. This reduces the discomfort felt by people walking on the flooring.

[0012] (5) In the flooring material of any one of (1) to (4), the reinforcing member is made of aluminum, wood, bamboo, or resin. This configuration allows the flooring material to be lighter than when the reinforcing member is made of iron.

[0013] (6) A building that solves the above problem is a building that includes a floor, and the floor includes any one of the flooring materials described in (1) to (5). According to this configuration, the discomfort suppression part included in the flooring material suppresses discomfort. Therefore, it is possible to suppress the discomfort caused to people by the flooring material itself.

[0014] (7) The building of (6) further includes a floor frame, the floor frame including a plurality of support members that support the floor material, the support members being spaced apart at intervals of a predetermined length or more, and the floor material being arranged such that the reinforcing members intersect with the support members in a plan view. With this configuration, the support members intersect with the reinforcing members of the floor material in a plan view. Therefore, the deflection of the floor material when a load is applied can be reduced compared to when the support members are arranged parallel to the reinforcing members. [Effects of the Invention]

[0015] The flooring material and building of the present disclosure can reduce the occurrence of discomfort. [Brief explanation of the drawings]

[0017] The flooring material 1 and the building 2 will be described with reference to FIGS. As shown in Figures 1 and 2, the building 2 comprises a building main body 3, a floor 4 provided outdoors, and a floor frame 5 that supports the floor 4. The building 2 in this embodiment is a two-story detached house. The building main body 3 is provided with a balcony 6 including the floor 4. The balcony 6 in this embodiment is a roof-mounted balcony. The roof-mounted balcony 6 is provided on the roof of the first-story portion of the building main body 3. The floor 4 of the balcony 6 includes flooring material 1. The floor 4 of the balcony 6 is surrounded by an outer wall 7 of the balcony 6.

[0018] The floor frame 5 comprises a plurality of support members 8 that support the floor material 1. In this embodiment, the support members 8 are made of lip channel steel. The plurality of support members 8 are arranged at intervals of at least a predetermined length. The floor frame 5 is made of a plurality of support members 8 and a plurality of connecting steel members 9 for connecting the plurality of support members 8. The plurality of connecting steel members 9 extend in a direction perpendicular to the extension direction of the plurality of support members 8 in a plan view. The ends of the support members 8 are joined to the connecting steel members 9 by welding. In this embodiment, the connecting steel members 9 are made of lip channel steel.

[0019] As shown in Figure 3, the floor frame 5 is installed on the roof of the first-story portion of the building body 3. Specifically, the floor frame 5 is placed on the roof material 10. In this embodiment, the roof material 10 is a folded-plate roof. The floor frame 5 is fixed to the roof material 10 by metal fittings that receive the floor frame 5.

[0020] The floor material 1 is placed on the floor frame 5. The floor material 1 is fixed to the floor frame 5 with screws that pass through recesses 15C (described later) in the floor material body 15. The floor material 1 is arranged so that the reinforcing members 16 intersect with the support members 8 in a plan view (see FIG. 2).

[0021] The exterior wall 7 of the balcony 6 is composed of a frame 7A and an exterior wall panel 7B attached to the frame 7A. The lower part of the frame 7A is connected to a support metal plate 11 attached to the ceiling beams 24 of the first floor portion. The exterior wall 7 of the balcony 6 is supported by the support metal plate 11.

[0022] A gap SA is formed between the exterior wall 7 of the balcony 6 and the floor 4. A drip board 12 is provided at the bottom of the gap SA. The drip board 12 is inclined toward the eaves gutter 13 that is installed along the eaves of the first-story portion.

[0023] The flooring material body 15 is provided with claw portions 18A (described later). The flooring material body 15 is arranged so that the claw portions 18A are directed toward the gap SA. This allows rainwater flowing on the flooring material 1 to run down the claw portions 18A into the gap SA. The rainwater is then guided by the drainage board 12 to the eaves gutter 13.

[0024] The thickness of the floor material 1 is set so that the floor material 1 fits into the building materials around the floor material 1. In one example, the thickness of the floor material 1 is 35 mm or less.

[0025] As shown in Figures 4 and 5, the flooring material 1 includes a flooring material body 15, a reinforcing member 16 disposed within the flooring material body 15, and a discomfort suppression part 17 that can suppress discomfort.

[0026] The flooring body 15 has an upper plate 18 and a lower plate 19 located below the upper plate 18. In this embodiment, the flooring body 15 is made of resin. For example, the flooring body 15 is made of polyvinyl chloride.

[0027] In the short direction of the flooring body 15, a claw portion 18A is provided at one first end portion 15A of the flooring body 15. The claw portion 18A has an upper surface 33 that is continuous with the upper surface 18C of the upper plate 18. The upper surface 33 has an inclined surface 34 that slopes from the upper plate 18 toward the tip of the claw portion 18A.

[0028] In the short direction of the flooring body 15, an opening 18B for engaging the claw portion 18A is provided at the other second end portion 15B of the flooring body 15. The opening 18B is formed by an upper flange portion 35 connected to the upper plate 18, a lower flange portion 36 connected to the lower plate 19, and a rising portion 37 rising from the lower flange portion 36.

[0029] Figure 4 shows two floor materials 1 engaged together. By engaging the claw portion 18A of one floor material 1 with the opening 18B of the other floor material 1, multiple floor materials 1 are connected in the short direction. In this embodiment, three floor materials 1 are connected on top of the floor frame 5 (see Figure 3). At the connecting portion, the end portion 35A of the upper flange portion 35 contacts the inclined surface 34. The inclination of the inclined surface 34 is formed so that when multiple floor materials 1 are connected, the upper surface 35B of the upper flange portion 35 and the upper surface 18C of the upper plate 18 are at the same height.

[0030] In this embodiment, the space S between the upper plate 18 and the lower plate 19 includes a first space SB and a second space SC. The first space SB and the second space SC are configured to extend in the longitudinal direction of the flooring body 15. Within the flooring body 15, the first space SB is defined by the upper plate 18, the lower plate 19, the first side plate 21, and the second side plate 22. The first side plate 21 constitutes the first end 15A of the flooring body 15 where the claw portion 18A is provided. The second side plate 22 constitutes part of the recess 15C of the flooring body 15. Furthermore, within the flooring body 15, the second space SC is defined by the upper plate 18, the lower plate 19, the third side plate 23, the upper flange portion 35, the lower flange portion 36, and the rising portion 37. The third side plate 23 constitutes part of the recess 15C of the flooring body 15.

[0031] The recess 15C is composed of a second side plate 22, a third side plate 23, and a lower plate 19. Within the recess 15C, locking grooves 26 are formed on the surfaces of the second side plate 22 and the third side plate 23. A lid 27 that covers the recess 15C is provided in the recess 15C. The lid 27 extends along the longitudinal direction of the flooring main 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 so that, when the locking claws 28 are locked into the locking grooves 26, the upper surface 18C of the upper plate 18 and the upper surface 27A of the lid 27 are continuous. The recess 15C is configured as a portion for driving screws that secure the flooring 1 to the floor frame 5. After screws are driven into the recess 15C to secure the flooring 1 to the floor frame 5, the lid 27 is attached to the recess 15C.

[0032] The flooring body 15 has a plurality of partition walls 25 that separate the space S between the upper plate 18 and the lower plate 19. The partition walls 25 are arranged parallel to one another. The partition walls 25 extend along the longitudinal direction of the flooring body 15. In this embodiment, the first space SB is separated by two partition walls 25. The second space SC is separated 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 spaces defined by the partition walls 25. The spaces defined by the 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 walls 25. Therefore, in this embodiment, the reinforcing member 16 extends along the longitudinal direction of the flooring main 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. The reinforcing member 16 is made of aluminum, wood, bamboo, or resin. In this 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 reduction section 17 is disposed within the flooring body 15. In this embodiment, the discomfort reduction section 17 includes a sound-absorbing material 30 and a buffer material 31. The sound-absorbing material 30 is disposed within the flooring body 15 as shown below. The sound-absorbing material 30 serving as the discomfort reduction section 17 is disposed in a hollow section 29 of the reinforcing member 16. Examples of the sound-absorbing material 30 include polystyrene foam, sponge, and glass wool. In this embodiment, the sound-absorbing material 30 is polystyrene foam. Furthermore, in this embodiment, the sound-absorbing material 30 fills the hollow section 29.

[0035] The cushioning material 31 is disposed within the flooring body 15 as shown below. The reinforcing member 16 has an outer peripheral surface 32 on the side opposite to the inner peripheral surface that defines the hollow portion 29. The cushioning material 31 serving as the discomfort suppression section 17 is disposed on at least a portion of the outer peripheral surface 32 that comes into contact with the flooring body 15. In this embodiment, the cushioning material 31 is formed from an elastic sheet-like member. The cushioning material 31 is attached to the entire periphery of the outer peripheral surface 32 of the reinforcing member 16. Examples of the cushioning material 31 include polystyrene foam, polyethylene sheets, sponges, and rubber sheets. In this embodiment, the cushioning material 31 is a polyethylene sheet.

[0036] The buffer material 31 is formed so that at least a portion of the buffer material 31 comes into contact with the upper plate 18 when the buffer 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 predetermined intervals. The cushioning materials 31 may also be attached to portions of the outer peripheral surface 32 that are not in contact with 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 discomfort suppression section 17, which includes sound absorbing material 30 and cushioning material 31, is disposed within the flooring body 15. The sound absorbing material 30 is disposed in the hollow section 29 of the reinforcing member 16. The cushioning material 31 is disposed on at least a portion of the outer circumferential surface 32 of the reinforcing member 16 that is in contact with the flooring body 15.

[0039] When people walk on flooring, they may feel uncomfortable due to the reverberation within the flooring or the uncomfortable feeling underfoot. Furthermore, people may feel uncomfortable due to the sound of objects falling or rainwater or hail hitting the flooring. According to this embodiment, the sound-absorbing material 30 suppresses the reverberation within the flooring 1. The buffer material 31 provides an appropriate feeling underfoot. This reduces the discomfort experienced by people.

[0040] The effects of this embodiment will be described. (1) The flooring material 1 comprises a flooring body 15, a reinforcing member 16 disposed within the flooring body 15, and a discomfort suppression portion 17 capable of suppressing discomfort. The flooring body 15 has an upper plate 18 and a lower plate 19 positioned below the upper plate 18. The reinforcing member 16 is disposed between the upper plate 18 and the lower plate 19. The discomfort suppression portion 17 is disposed within the flooring body 15. With this configuration, the discomfort suppression portion 17 suppresses discomfort. Therefore, the discomfort caused to people by the flooring body 15 can be suppressed.

[0041] (2) The flooring body 15 has a plurality of partition walls 25 that separate the space S between the upper plate 18 and the lower plate 19. The plurality of partition walls 25 are arranged parallel to one another. The reinforcing member 16 is arranged in at least one of the spaces formed by the plurality of partition walls 25. If the flooring material flexes when walking on it, it may cause discomfort to people. With the above configuration, the reinforcing member 16 and the plurality of partition walls 25 prevent the flooring material 1 from flexing. This prevents discomfort experienced by people walking on the flooring material 1.

[0042] (3) Reinforcing member 16 is configured to extend along partition wall 25. Reinforcing member 16 has a hollow portion 29 extending in the longitudinal direction of reinforcing member 16. Sound absorbing material 30 serving as discomfort reduction portion 17 is disposed in hollow portion 29.

[0043] If the reinforcing member has a hollow portion, there is a risk that if an object falls on the flooring material, sound will resonate in the hollow portion. Furthermore, if the reinforcing member of a flooring material placed outdoors has a hollow portion, there is a risk that rainwater or hail will fall and hit the flooring material, causing sound to resonate in the hollow portion. Because such sounds are not natural sounds, they may cause discomfort to people. According to the above configuration, the sound-absorbing material 30 suppresses sound from resonating within the flooring body 15. This reduces the discomfort caused by sounds generated when objects, rainwater, hail, etc. hit the flooring material 1.

[0044] (4) The reinforcing member 16 is configured to extend along the partition wall 25. The reinforcing member 16 has a hollow portion 29 extending 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 defines the hollow portion 29. A buffer material 31 is disposed on at least a portion of the outer peripheral surface 32 that comes into contact with the flooring body 15.

[0045] If the flooring material is hard, it may be uncomfortable to walk on. In this regard, with the above-described configuration, by disposing the buffer material 31 between the flooring body 15 and the reinforcing member 16, it is possible to provide the flooring material 1 with appropriate cushioning properties. This makes it possible to reduce the discomfort felt by people walking on the flooring material 1.

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

[0047] (6) The building 2 has a floor 4. The floor 4 includes a flooring material 1. According to this configuration, the discomfort suppression part 17 included in the flooring material 1 suppresses discomfort. Therefore, the occurrence of discomfort caused to people by the flooring body 15 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 support members 8 are arranged at intervals of a predetermined length or more. In a plan view, the floor material 1 is arranged so that the reinforcing members 16 intersect with the support members 8. According to this configuration, the support members 8 intersect with the reinforcing members 16 of the floor material 1 in a plan view. Therefore, the deflection of the floor material 1 when a load is applied can be reduced compared to when the support members 8 are arranged parallel to the reinforcing members 16.

[0049] <Modification> The above-described embodiments are examples of possible forms of the flooring material 1 and the building 2, and are not intended to limit the forms. The flooring material 1 and the building 2 may take forms different from those illustrated in the above-described embodiments. Examples of such forms include forms in which part of the configuration of the embodiment is replaced, modified, or omitted, or forms in which a new configuration is added to the embodiment. An example of a modified embodiment is shown below.

[0050] As shown in FIG. 6, the cushioning material 31 may be attached only to the upper outer peripheral surface 32 of the reinforcing member 16. The cushioning material 31 may be configured to contact the upper plate 18 at the upper outer peripheral surface 32 of the reinforcing member 16. Specifically, the thickness is adjusted by stacking multiple cushioning materials 31. Alternatively, the cushioning material 31 is filled between the upper plate 18 and the upper outer peripheral surface 32 of the reinforcing member 16. By arranging the cushioning material 31 between the flooring body 15 and the reinforcing member 16, it is possible to impart appropriate cushioning properties to the flooring material 1. This makes it possible to reduce the discomfort felt by the flooring material 1 when people walk on it.

[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 rectangular. In the rectangular cross section, the corners of the reinforcing member 16 are chamfered to form a curved surface. For example, the reinforcing member 16 is a square pipe. Furthermore, the entire outer peripheral surface 32 of the reinforcing member 16 may be covered by a single cushioning material 31.

[0052] As shown in FIG. 8 , the discomfort reduction units 17 may be disposed only in a major portion of the flooring body 15. Furthermore, if the flooring 1 is located in a portion where people rarely walk, the discomfort reduction units 17 may not be disposed in the flooring body 15 below that portion. For example, the portion of the floor 4 that includes the unengaged opening 18B is adjacent to a place where people enter and exit, such as a French window 14. The area near this opening 18B is where people walk. Therefore, sound-absorbing material 30 and buffer material 31 are disposed in the second space SC adjacent to the opening 18B. Furthermore, the portion of the floor 4 that includes the unengaged claw portion 18A is adjacent to the exterior wall 7 of the balcony 6. The area near this claw portion 18A is where people rarely walk. Therefore, only the reinforcing member 16 is disposed in the first space SB adjacent to the claw portion 18A. In this manner, the discomfort reduction units 17 may be disposed depending on the layout of the flooring 1. This allows the flooring 1 to be made lighter.

[0053] The sound absorbing material 30 does not have to fill the hollow portion 29. The sound absorbing material 30 may be disposed in a part of the hollow portion 29. This allows the cost of the flooring material 1 to be reduced.
