Description

[Technical field]

[0001] The present disclosure relates to flooring structures and flooring supports. [Background technology]

[0002] Patent Document 1 discloses a double floor structure. The double floor structure is composed of multiple support legs erected on a floor slab, a panel support base screwed and fixed to the support legs, and multiple floor panels mounted on the panel support base. The panel support base has a panel support plate portion on which the floor panel is placed, and four nuts screwed into the floor panel fixing bolts that fix the floor panel to the panel support base.

[0003] Patent Document 2 discloses a simple assembly deck. This simple assembly deck is composed of a base, a plate, and a number of fasteners for attaching the plate to the base. The plate has two parallel grooves, a left groove and a right groove, on the bottom surface. The fasteners are attached to the top surface of the frame in a line for the number of rows of the plate. The fasteners are composed of a plate and a first protrusion, a second protrusion, a third protrusion, and a fourth protrusion of a pair of left and right leaf spring pieces with bulges on the outer ends, which are erected in two rows at four locations on the plate, and are fixed to the frame with screws. The fasteners are fitted into the left and right grooves of the plate into the first protrusion, the second protrusion, the third protrusion, and the fourth protrusion. The left and right leaf spring pieces of the fastener deform in the direction toward each other at the narrowed portions at the entrance to the left and right grooves of the plate material, and when they fit into the expanded portions at the back of the left and right grooves, the spring force is again applied in the direction toward the left and right leaf spring pieces moving apart, and the bulges are locked in the expanded portions of the left and right grooves. On the other hand, if the plate material is pulled strongly, the left and right leaf spring pieces can be separated. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2022-33460 [Patent Document 2] JP 2023-53838 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the double floor structure described in Patent Document 1, the floor panel (floor material) needs to be fixed to the panel receiving base (floor material support) on the support leg with floor panel fixing bolts (hereinafter simply referred to as "bolts"), which increases the number of labor hours required to install the floor panel and takes time. In addition, since fixing members such as bolts are visible on the surface of the floor panel, the design may be reduced, and in order to improve the design, it may become necessary to install a floor finishing material or the like on the floor panel. In addition, since the floor panel and the panel receiving base are fixed with bolts, the bolts must be loosened and removed when removing the floor panel from the panel receiving base during renovation, etc., which increases the number of labor hours required and takes time.

[0006] In the simple assembly deck described in Patent Document 2, two grooves are provided on the bottom surface of the board (floor material), and the left and right grooves of the board are fitted into the first, second, third and fourth protrusions of the fastener (floor material support). Therefore, when installing the board, it is difficult to see the relative positions of the two grooves on the bottom surface of the board and the first, second, third and fourth protrusions of the fastener, making the work difficult. In addition, a strong force is required to remove the board from the fastener during repairs, making the work complicated and time-consuming.

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0021] Fig. 1 is an explanatory diagram of a floor structure according to one embodiment of the present invention, where (a) shows a state as viewed from above and (b) shows a state as viewed from the side. Fig. 2 is a perspective view of a floor material according to this embodiment. Fig. 3 is a cross-sectional view taken along the line III-III in Fig. 2. Fig. 4 is a side view of a support leg and a floor material support. Fig. 5 is a perspective view of the floor material support. Fig. 6 is a side view of the floor material support. Fig. 7 is a plan view of the floor material support.

[0022] The floor structure according to the present disclosure is a floor structure in which at least one floor material 3 is laid on a floor slab (base) 2 via a floor material support 4 or the like. In this embodiment, a floor structure 1 in which multiple floor materials 3 are laid via support legs 5 and floor material supports 4 provided on the floor slab 2 will be described. Note that the base is not limited to the floor slab 2, and may be any support that serves as a base for supporting the floor material 3.

[0023] As shown in Fig. 1, the floor structure 1 according to this embodiment is a double floor structure that supports multiple floor materials 3 via support legs 5 and the like installed on a floor slab 2. The floor structure 1 includes the support legs 5, a floor material support 4, and multiple floor materials 3.

[0024] As shown in Figures 1 to 3, the floor material 3 is a plate-like member that intersects in the vertical direction, and has a recess 6 on a side surface 3a. The shape of the floor material 3 when viewed from above is not particularly limited, but is preferably a square or rectangular shape (including a long plate shape). In this embodiment, the floor material 3 will be described as having a square shape.

[0025] The recess 6 of the flooring 3 is provided in the middle part of the thickness direction of the flooring 3, and is formed in a groove shape extending along the extension direction of the side of the flooring 3. In this embodiment, the recess 6 of the flooring 3 is provided over the entire periphery of the flooring 3. As shown in FIG. 3, convex parts 7a and 7b are formed above and below the recess 6 of the flooring 3. In this embodiment, the upper convex part 7a of the flooring 3 protrudes outward more than the lower convex part 7b. In this embodiment, the recess 6 of the flooring 3 is provided over the entire periphery of the flooring 3, but this is not limited to this, and the recess 6 may be provided only in a necessary area (for example, in this embodiment, near the corner part 3b of the flooring 3). In this embodiment, the upper convex part 7a protrudes outward more than the lower convex part 7b, but this is not limited to this, and the upper convex part 7a may protrude by approximately the same amount as the lower convex part 7b, or the lower convex part 7b may protrude outward more than the upper convex part 7a.

[0026] As shown in FIG. 1, in the floor structure 1 of this embodiment, a plurality of floor materials 3 are laid out so that the boundary lines BL of each floor material 3 extend in a lattice pattern in a first direction (X direction shown in FIG. 1(a)) intersecting the vertical direction and a second direction (Y direction shown in FIG. 1(a)) perpendicular to the first direction. That is, among the plurality of floor materials 3, the corners 3b (see FIG. 2) of four floor materials 3 are arranged so as to gather at a predetermined position P. In this embodiment, the support legs 5 and floor material supports 4 are arranged below the positions (positions P) where the corners 3b of each floor material 3 are adjacent to each other. That is, in the floor structure 1 of this embodiment, the support legs 5 and floor material supports 4 are provided at a plurality of positions. In the following, the support legs 5 and floor material supports 4 arranged below the position P where the corners 3b of the four predetermined floor materials 3 (four floor materials 3A to 3D shown in FIG. 1(a)) gather among the plurality of support legs 5 and floor material supports 4 will be described.

[0027] As shown in Figure 4, the support leg 5 is positioned at a predetermined position P (see Figure 1 (a)) between the floor slab 2 and the floor material 3, and is a member that supports the floor material 3 from below, and has a base portion 8, a support pillar 9, and a support base 10.

[0028] The base 8 of the support leg 5 is a portion that supports the support leg 5, and is placed on the floor slab 2. The base 8 in this embodiment is formed in a plate shape that crosses the up-down direction. An elastic material such as cushion rubber may be provided on the lower surface of the base 8.

[0029] The support pillar 9 of the support leg 5 is a columnar member extending in the vertical direction, and its lower end is supported by the base portion 8. A support base 10 is attached to the upper end of the support pillar 9.

[0030] The support base 10 of the support leg 5 has a mounting portion 10a attached to the upper end of the support post 9, and a plate-shaped upper plate portion 10b provided integrally with the upper portion of the mounting portion 10a. The upper plate portion 10b is formed in a shape that allows the flooring material support 4 to be attached. In this embodiment, the upper plate portion 10b is formed in a square shape when viewed from above, and has a size that allows it to support the corner portions 3b of the four flooring materials 3A to 3D from below.

[0031] The support leg 5 may have an adjustment mechanism capable of adjusting the height position of the support base 10. For example, a male screw portion (not shown) may be provided on the upper part of the support column 9, and a female screw portion (not shown) that screws into the male screw portion may be provided on the mounting portion 10a of the support base 10, and the height position of the support base 10 may be adjusted by rotating the support column 9 and the support base 10 relatively. Note that the configuration of the support leg 5 is not limited to the above, and it may be configured to be disposed between the floor slab 2 and the floor material 3, and to be capable of mounting the floor material support 4 to the upper end portion.

[0032] As shown in Figures 4 to 7, the floor material support 4 is a member for supporting at least one floor material 3 (four floor materials 3A to 3D in this embodiment), and is placed between the floor slab 2 and the floor material 3, and is supported directly or indirectly by the floor slab 2. The floor material support 4 in this embodiment is indirectly supported by the floor slab 2 via support legs 5. The floor material support 4 may also be used by placing it directly on the floor slab 2 without being attached to the support legs 5.

[0033] The flooring support 4 comprises a base 11 that supports an end of the flooring 3 (corner 3b in this embodiment) from below, and a protrusion 12 that protrudes upward from the base 11. In addition to the base 11 and protrusion 12, the flooring support 4 of this embodiment also comprises a claw 13 that can be engaged with the upper plate 10b at the upper end of the support leg 5. The material constituting the flooring support 4 only needs to be flexible, and is preferably made of resin in particular.

[0034] The base portion 11 of the flooring support 4 is a portion that supports the end portion (corner portion 3b in this embodiment) of the flooring 3 from below. The base portion 11 is formed, for example, in the shape of a plate that crosses the vertical direction. The shape of the base portion 11 is not particularly limited, but in this embodiment, it is formed in a square shape that is slightly larger than the upper plate portion 10b of the support leg 5. The base portion 11 in this embodiment has a size that can support the corner portions 3b of the four floorings 3A to 3D from below. The base portion 11 is located below the corner portions 3b of the four floorings 3A to 3D and supports the corner portions 3b of the four floorings 3A to 3D from below. The four floorings 3A to 3D have four sets of two floorings 3 adjacent to each other (floorings 3A, 3B, floorings 3C, 3D, floorings 3A, 3C, floorings 3B, 3D). That is, the base portion 11 is located below the adjacent ends of the two floor materials 3 (floor materials 3A and 3B, floor materials 3C and 3D, floor materials 3A and 3C, or floor materials 3B and 3D) and supports the ends of the two floor materials 3 from below. Note that the base portion 11 may be provided with an opening or the like for weight reduction or the like.

[0035] The protrusions 12 of the flooring support 4 are disposed between the opposing side surfaces 3a of the two floorings 3 (see FIG. 4). As described above, the four floorings 3A to 3D have four pairs of two adjacent floorings 3, so at least four protrusions 12 are provided. Specifically, as shown in FIG. 7, the flooring support 4 of this embodiment is provided with a protrusion 12 (hereinafter sometimes referred to as "protrusion 121") between the floorings 3A and 3B, a protrusion 12 (hereinafter sometimes referred to as "protrusion 122") between the floorings 3C and 3D, a protrusion 12 (hereinafter sometimes referred to as "protrusion 123") between the floorings 3A and 3C, and a protrusion 12 (hereinafter sometimes referred to as "protrusion 124") between the floorings 3B and 3D. The protrusion 121 is disposed at the center of the base 11 in the second direction (Y direction) and on one side of the center in the first direction (X direction) (upper side in FIG. 7). The protrusion 122 is disposed at the center of the base 11 in the second direction and on the other side of the center in the first direction (lower side in FIG. 7). The protrusion 123 is disposed at the center of the base 11 in the first direction and on one side of the center in the second direction (left side in FIG. 7). The protrusion 124 is disposed at the center of the base 11 in the first direction and on the other side of the center in the second direction (right side in FIG. 7). In the following description, "two floor materials 3" refers to two floor materials 3 located on both sides of the protrusion 12.

[0036] The protrusion 12 has a leg 14 that stands from the base 11, and a locking portion 15 that protrudes from the leg 14 toward the side surface 3a of the flooring material 3 and locks into the recess 6. The protrusion 12 of this embodiment has a slit 16 that is recessed downward from the upper end and extends in a direction that intersects with the opposing direction of the side surfaces 3a of the two flooring materials 3 (hereinafter, sometimes simply referred to as the "opposing direction").

[0037] The legs 14 of the protrusions 12 stand up from the base 11 and are disposed at positions facing both side surfaces 3a of the two floor materials 3. In this embodiment, the legs 14 are formed in a plate shape extending along the extension direction of the side surfaces 3a of the two floor materials 3 and stand up from the base 11. Specifically, the legs 14 of the protrusions 121 and 122 are formed in a plate shape extending along the first direction (X direction). Moreover, the legs 14 of the protrusions 123 and 124 are formed in a plate shape extending along the second direction (Y direction).

[0038] The protrusion 12 of this embodiment has two locking parts 15 that protrude from the upper part of the leg 14 to both sides in the opposing direction of the side surfaces 3a of the two floor materials 3, and locks the recesses 6 on the side surfaces 3a of the two floor materials 3. The "opposing direction" is the direction in which the side surfaces 3a of the two floor materials 3 sandwiching each protrusion 12 face each other, and differs depending on the arrangement position of each protrusion 12. For example, in this embodiment, the opposing direction of the protrusions 121 and 122 is the second direction, and the opposing direction of the protrusions 123 and 124 is the first direction. That is, the protrusion 121 has two locking parts 15 that protrude from the leg 14 to both sides in the opposing direction (second direction) of the side surfaces 3a of the two floor materials 3A and 3B, and locks the recesses 6 on the side surfaces 3a of the two floor materials 3A and 3B. The protrusion 122 has two locking portions 15 that protrude from the leg 14 to both sides in the opposing direction (second direction) of the side surfaces 3a of the two floor materials 3C, 3D and lock the recesses 6 in the side surfaces 3a of the two floor materials 3C, 3D. The protrusion 123 has two locking portions 15 that protrude from the leg 14 to both sides in the opposing direction (first direction) of the side surfaces 3a of the two floor materials 3A, 3C and lock the recesses 6 in the side surfaces 3a of the two floor materials 3A, 3C. The protrusion 124 has two locking portions 15 that protrude from the leg 14 to both sides in the opposing direction (first direction) of the side surfaces 3a of the two floor materials 3B, 3D and lock the recesses 6 in the side surfaces 3a of the two floor materials 3B, 3D.

[0039] The slit 16 of the protrusion 12 is disposed between the two locking portions 15 and extends in a direction intersecting the facing direction while being recessed downward. The slit 16 in this embodiment is disposed above the leg 14. That is, the two locking portions 15 of the protrusion 12 are disposed on both sides of the slit 16 and protrude in a direction away from the slit 16. As a result, the two locking portions 15 have the desired flexibility and are elastically deformable in the opposite direction to the protruding direction. In this embodiment, the locking portion 15 of the protrusion 12 has the flexibility required when installing the flooring material 3 described later, but this is not limited to this, and it is sufficient that at least one of the leg 14 and the locking portion 15 has the required flexibility. For example, the leg 14 of the protrusion 12 may have the required flexibility without providing the slit 16, and the upper end side of the protrusion 12 may be elastically deformable in the facing direction with the lower end side of the leg 14 as an axis.

[0040] As shown in FIG. 6, the locking portion 15 of the protrusion 12 preferably has an upper inclined surface 17 that extends downward in the protruding direction from above, and a lower inclined surface 18 that is located below the upper inclined surface 17 and extends upward in the protruding direction from below. The cross-sectional shape of the locking portion 15 of the protrusion 12 (cross-sectional shape along the protruding direction and up-down direction of the locking portion 15) is not particularly limited, but is preferably a semicircular shape that bulges in the protruding direction. The protrusion 12 of this embodiment has a cylindrical portion above the plate-like leg portion 14, and by providing a slit 16, the locking portion 15 has a semicircular cross-sectional shape on both sides of the slit 16. In this embodiment, the locking portion 15 of the protrusion 12 has a semicircular cross-sectional shape, and thus has a curved upper inclined surface 17 and a lower inclined surface 18, but is not limited thereto. For example, the locking portion 15 may be formed in a substantially triangular cross-sectional shape and have a linear upper inclined surface 17 and a linear lower inclined surface 18.

[0041] The claw portion 13 of the flooring support 4 is a portion for attaching the flooring support 4 to the upper plate portion 10b (upper end portion) of the support leg 5, and is formed so as to be able to be engaged with the upper plate portion 10b. The claw portion 13 in this embodiment is provided on the outer edge portion of the base portion 11, and has a plate-shaped portion 13a protruding downward from the lower surface of the base portion 11, and a claw body 13b protruding from the lower end portion of the plate-shaped portion 13a toward the inside of the base portion 11. The claw portions 13 are provided at eight locations in total, two on each side of the base portion 11. The size of the area defined by the inner surface of the plate-shaped portion 13a of each claw portion 13 is set to be approximately the same size as the upper plate portion 10b of the support leg 5, or slightly larger. In addition, the vertical length from the lower surface of the base portion 11 to the claw body 13b is set to be approximately the same as the thickness of the upper plate portion 10b of the support leg 5, or slightly longer. The claw body 13b of the claw portion 13 has an inclined surface 19 (see FIG. 6) that inclines from below toward the inside of the base portion 11 and upward. In the drawings, some of the claw portions 13 are omitted. The shape of the claw portion 13 is not limited to the above, and may be any shape that can be engaged with the upper end portion of the support leg 5 (the upper plate portion 10b in this embodiment). In this embodiment, the claw portion 13 is formed so as to be engaged with the outer edge of the upper plate portion 10b of the support leg 5, but is not limited thereto. For example, an opening or the like may be provided in the upper plate portion 10b of the support leg 5, and the claw portion 13 may be formed so as to be engaged with the opening. In addition, the number of claw portions 13 provided is not limited to the above, and can be set appropriately.

[0042] Next, an explanation will be given of the construction of the floor structure 1. Figure 8 is an explanatory diagram of a method for installing the floor material, where (a) shows the state before one side is locked, and (b) shows the state after both sides are locked.

[0043] When constructing the floor structure 1, as shown in FIG. 4, first, the support leg 5 with the floor material support 4 attached is placed at a predetermined position P (see FIG. 1(a)) on the floor slab 2. Alternatively, the support leg 5 before the floor material support 4 is attached is placed at a predetermined position P on the floor slab 2, and then the floor material support 4 is attached to the support leg 5. When attaching the floor material support 4 to the support leg 5, the floor material support 4 is brought close to the upper plate portion 10b of the support leg 5 so that the lower surface of the base portion 11 of the floor material support 4 faces the upper surface of the upper plate portion 10b of the support leg 5, and the inclined surface 19 of the claw body 13b of the claw portion 13 is abutted against the outer edge of the upper plate portion 10b of the support leg 5. When the flooring support 4 is pressed from this state toward the upper plate 10b of the support leg 5, the inclined surface 19 of the claw portion 13 is pressed upward, causing the plate portion 13a of the claw portion 13 to elastically deform toward the outside of the base portion 11, and the outer edge of the upper plate portion 10b of the support leg 5 to move upward along the inclined surface 19 of the claw portion 13. Then, when the upper plate portion 10b of the support leg 5 moves upward over the claw body 13b of the claw portion 13 of the flooring support 4, the claw portion 13 returns to its original shape due to its elastic force, and the claw body 13b of the claw portion 13 engages the upper plate portion 10b of the support leg 5. In this way, the flooring support 4 is attached to the support leg 5. When attaching the flooring support 4 to the support leg 5, multiple claw portions 13 may be engaged with the upper plate portion 10b of the support leg 5 at approximately the same time, or the claw portion 13 on one side in the first direction (or second direction) may be engaged with the upper plate portion 10b of the support leg 5, and then the flooring support 4 may be pressed toward the upper plate portion 10b of the support leg 5 to engage the claw portion 13 on the other side in the first direction (or second direction) with the upper plate portion 10b of the support leg 5.

[0044] Next, after adjusting the height of the support leg 5 to an appropriate height, multiple floor materials 3 are laid above the support leg 5. Specifically, multiple floor materials 3 are attached to the floor material support 4 above the support leg 5. When attaching the floor material 3 to the floor material support 4 above the support leg 5, as shown in FIG. 8(a), first, the floor material 3 is tilted so that one side of the floor material 3 (one side in the second direction in FIG. 8(a) (hereinafter sometimes referred to as the "left side")) faces downward, and the recess 6 on the left side surface 3a of the floor material 3 is engaged with the engaging portions 15 (in FIG. 8(a) shown as "engaging portions 15A") of the protrusions 12 of the two floor material supports 4 located below the two corners 3b on the left side of the floor material 3. Then, the other side in the second direction of the flooring 3 (the other side in the second direction in Figure 8(a) (hereinafter sometimes referred to as the "right side")) is moved downward, and the lower edge of the right side of the flooring 3 is abutted from above against the locking portions 15 (shown as "locking portions 15B" in Figure 8(a)) of the protrusions 12 of the two flooring support members 4 located below the two corners 3b on the right side of the flooring 3 (see Figure 8(a)). At this time, the recesses 6 (not shown) on both sides in the first direction located on the left side of the flooring 3 may be locked with the locking portions 15 (shown as "locking portions 15C" in Figure 8(a)) of the other protrusions 12 of the two flooring support members 4 on the left side.

[0045] Next, the right side of the floor material 3 is pressed downward. When the right side of the floor material 3 is pressed downward, the upper inclined surface 17 (see FIG. 6) of the locking portion 15B of the protrusion 12 of the two floor material supports 4 on the right side is pressed downward, so that the locking portion 15B is elastically deformed in the opposite direction to its protruding direction (to the right in FIG. 8(a)). With this elastic deformation of the locking portion 15B, the right end of the floor material 3 moves downward along the upper inclined surface 17 of the locking portion 15B. That is, at least one of the leg portion 14 and the locking portion 15 of the protrusion 12 of the floor material support 4 (the locking portion 15 in this embodiment) has flexibility, and when the end of the side surface 3a of the floor material 3 abuts against the protrusion 12 from above when the floor material 3 is installed on the floor material support 4, it is elastically deformed in the opposite direction to the protruding direction of the locking portion 15, allowing the floor material 3 to move downward. Then, when the lower convex portion 7b (see FIG. 3) on the right side surface 3a of the flooring 3 moves downward over the locking portion 15B, the locking portion 15B returns to its original shape due to its elastic force, and locks into the recessed portion 6 on the right side surface 3a of the flooring 3 (see FIG. 8(b)). At this time, the recessed portions 6 (not shown) on both sides in the first direction located on the right side of the flooring 3 are also locked into the locking portions 15 (shown as "locking portions 15D" in FIG. 8(b)) of the other protrusions 12 of the two flooring material supports 4 on the right side.

[0046] As shown in Figures 7 and 8(b), when multiple flooring materials 3 are attached to the flooring support 4 above the support legs 5 as described above, it is preferable to provide a gap g between two adjacent flooring materials 3.

[0047] Next, the work of peeling off the flooring 3 during repair work etc. will be described. When removing the flooring 3 attached to the flooring support 4, a desired tool is inserted between the adjacent flooring 3 from one edge of the flooring 3 (gap g in this embodiment), and the inserted tool is tilted outward. When the tool is tilted outward, one end of the flooring 3 is lifted upward by the principle of leverage, and the lower convex portion 7b of one side surface 3a of the flooring 3 abuts against the locking portion 15 of the protrusion 12 of the flooring support 4. When the lower convex portion 7b of the flooring 3 abuts against the locking portion 15 of the protrusion 12 of the flooring support 4, one end of the flooring 3 moves upward while elastically deforming the protrusion 12 (locking portion 15 in this embodiment) in the opposite direction to the protruding direction of the locking portion 15. When the convex portion 7b on the underside of the flooring 3 moves above the locking portion 15 of the protrusion 12 of the flooring support 4, the locking of one end of the flooring 3 by the locking portion 15 of the protrusion 12 of the flooring support 4 is released. Then, by lifting the flooring 3 in this state, it can be removed from the flooring support 4. Note that the tool used when removing the flooring 3 is not limited to the above-mentioned tool that is inserted between adjacent flooring materials 3, and may be, for example, a tool having a suction cup that can be attached to the surface of the flooring 3 and a gripping portion that can be gripped.

[0048] In the floor structure 1 and floor material support 4 configured as described above, the protrusion 12 of the floor material support 4 has a leg 14 that stands up from the base 11 and is arranged at a position facing the side surface 3a of the floor material 3, and a locking portion 15 that protrudes from the leg 14 toward the side surface 3a of the floor material 3 and locks the recess 6. At least one of the leg 14 and the locking portion 15 of the protrusion 12 of the floor material support 4 (the locking portion 15 in this embodiment) is flexible, and when the end of the side surface 3a of the floor material 3 abuts against the protrusion 12 from above when the floor material 3 is installed on the floor material support 4, it elastically deforms in the direction opposite to the protruding direction of the locking portion 15, allowing the floor material 3 to move downward. Therefore, the floor material 3 can be laid with one touch by the simple task of pressing the floor material 3 toward the floor material support 4 (downward).

[0049] Furthermore, since the locking portion 15 of the protrusion 12 of the flooring support 4 locks into the recess 6 in the side surface 3a of the flooring 3, the flooring 3 can be laid without using fixing members such as screws.

[0050] Furthermore, since the flooring 3 can be laid without using fixing members such as screws, screw heads and the like are not exposed on the surface (upper surface) of the flooring 3, resulting in a high level of design.

[0051] In addition, because the recesses 6 of the flooring 3 are locked with the flexible protrusions 12, the flooring 3 can be easily removed from the flooring support 4 using the above-mentioned tools during renovations, etc. For example, unlike when fixing is performed using fixing members such as screws, there is no need to loosen the screws, and the flooring 3 can be easily removed from the flooring support 4.

[0052] Furthermore, since the flooring material 3 can be laid without using fixing members such as screws, the number of steps required for installing and removing the flooring material 3 can be reduced, and the work time can be shortened.

[0053] In addition, a recess 6 is provided on the side surface 3a of the flooring 3, and the locking portion 15 of the protrusion 12 of the flooring support 4 locks into the recess 6 provided on the side surface 3a of the flooring 3, so that the positions of the protrusion 12 of the flooring support 4 and the recess 6 of the flooring 3 can be easily recognized from above when installing and removing the flooring 3. This improves workability when installing and removing the flooring 3.

[0054] In addition, because the recesses 6 provided on the side surface 3a of the flooring 3 are engaged, unlike when a groove or the like is provided in the middle part of the underside of the flooring 3 in the first direction (or second direction) and the groove is engaged, the distance between the position where the flooring 3 is inserted between the two flooring materials 3 and the engaged part of the flooring 3 can be made closer. Therefore, when using a tool to be inserted between the two flooring materials 3, the force from the tool can be input to a position close to the engaged part of the flooring 3, so the flooring 3 can be easily removed from the flooring material support 4.

[0055] As described above, according to this embodiment, it is possible to provide a floor structure 1 and a floor material support 4 that allow for good workability when installing and removing the floor material 3 and also allows for improved design.

[0056] Furthermore, since the recess 6 is provided on the side surface 3a of the floor material 3, unlike when a groove or the like is provided on the underside of the floor material 3, for example, the strength of the floor material 3 against loads from above can be ensured.

[0057] In addition, the protrusion 12 of the flooring support 4 is provided with two locking portions 15 that lock into the recesses 6 on the side surfaces 3a of the two flooring materials 3, so that one protrusion 12 can support two flooring materials 3.

[0058] Furthermore, the flooring support 4 has four protrusions 12, each of which is disposed between the opposing side surfaces 3a of two adjacent flooring materials 3 among the four flooring materials 3, so that one flooring support 4 can support four flooring materials 3. Also, the flooring material 3 can be firmly supported from all four sides.

[0059] Furthermore, the locking portion 15 of the protrusion 12 of the flooring support 4 has an upper inclined surface 17 that extends from above at a downward incline in the protruding direction, and a lower inclined surface 18 that is located below the upper inclined surface 17 and extends from below at an upward incline in the protruding direction. Therefore, the protrusion 12 can be easily elastically deformed in the direction opposite to the protruding direction of the locking portion 15 by a force from above on the upper inclined surface 17 of the locking portion 15, and a force from below on the lower inclined surface 18 of the locking portion 15. This further improves the ease of installation and removal of the flooring 3.

[0060] Furthermore, by making the cross-sectional shape of the locking portion 15 of the protrusion 12 of the flooring support 4 (the cross-sectional shape along the protruding direction and the up-down direction of the locking portion 15) semicircular in shape that bulges in the protruding direction of the locking portion 15, the upper inclined surface 17 and the lower inclined surface 18 can be made into gently curved surfaces. As a result, when the flooring 3 is installed, the locking portion 15 can easily lock into the recess 6 of the flooring 3, and when the flooring 3 is removed, the locking of the locking portion 15 into the recess 6 of the flooring 3 can easily be released, making it easy to attach and detach the flooring 3 to and from the floor support 4.

[0061] Furthermore, the protrusion 12 of the flooring support 4 has a slit 16 that is disposed between the two locking portions 15 and extends in a direction intersecting the opposing direction while being recessed downward. With this simple structure of providing the slit 16, the protrusion 12 can have the necessary flexibility and be elastically deformed.

[0062] In addition, since the base portion 11 of the floor material support 4 is supported by the upper plate portion 10b (upper end portion) of the support leg 5, by using the floor material support 4 in a double floor structure in which the support leg 5 is erected on the floor slab 2 and the floor material 3 is laid above the support leg 5, it is possible to improve workability when installing and removing the floor material 3 and also to improve the design.

[0063] Furthermore, since the flooring support 4 has claws 13 that can be engaged with the upper ends of the support legs 5, the flooring support 4 can be easily attached to the upper ends of conventionally used general support legs 5. In other words, by utilizing conventionally used general support legs 5, it is possible to improve the workability when installing and removing the flooring 3, and also to improve the design.

[0064] In addition, by providing a gap g between two adjacent floor materials 3 of the floor structure 1, it becomes easier to insert the above-mentioned tools etc. between the two floor materials 3 when removing the floor materials 3 during renovation, etc., thereby further improving workability when removing the floor materials 3.

[0065] In this embodiment, the flooring support 4 is placed below the position P where the corners 3b of the four flooring materials 3A to 3D meet, but the present invention is not limited to this. Fig. 9 is a perspective view showing a first modified example of the flooring support. Fig. 10 is a perspective view showing a second modified example of the flooring support. In Figs. 9 and 10, the same reference numerals are used for configurations similar to those in the above embodiment.

[0066] For example, as shown in FIG. 9, a flooring support 4A of a first modified example (hereinafter, simply referred to as "flooring support 4A") may be placed below the ends of two adjacent floorings 3E, 3F (position P' shown in FIG. 1(a)). The flooring support 4A includes a base portion 11 that supports the ends of the floorings 3E, 3F from below, a protrusion portion 12 that protrudes upward from the base portion 11, and a claw portion 13 that can be engaged with the upper plate portion 10b at the upper end of the support leg 5. The flooring support 4A has two protrusion portions 12 that are placed between the two floorings 3E, 3F. The two protrusion portions 12 are placed in the center of the base portion 11 in the second direction (Y direction) and on both sides in the first direction (X direction). The positions of the two protrusion portions 12 provided on the flooring support 4A are not limited to the above, and may be placed between the side surfaces 3a of the two floorings 3E, 3F. Furthermore, the number of protrusions 12 provided on the floor material support 4A is not limited to two, but may be one, or three or more.

[0067] Alternatively, as shown in FIG. 10, a flooring support 4B of a second modified example (hereinafter simply referred to as "flooring support 4B") may be placed below the end of one of the flooring materials 3G (position P" shown in FIG. 1(a)). The flooring support 4B comprises a base portion 11 that supports the end of the flooring material 3G from below, a protrusion 20 that protrudes upward from the base portion 11, and a claw portion 13 that can be engaged with the upper plate portion 10b at the upper end of the support leg 5. The flooring support 4B has two protrusions 20 that are positioned opposite the side surface 3a of one of the flooring materials 3G. The two protrusions 20 are positioned in the center of the base portion 11 in the first direction (X direction) and on both sides in the second direction (Y direction). The protrusions 20 are attached to the legs 1 that stand up from the base portion 11. 4 and one locking portion 15 that protrudes from the leg 14 toward the side surface 3a of the flooring 3G and locks the recess 6. At least one of the leg 14 and the locking portion 15 of the protrusion 20 is flexible, and when the end of the side surface 3a of the flooring 3 abuts against the protrusion 20 from above when the flooring 3 is installed on the flooring support 4, the protrusion 20 elastically deforms in the opposite direction to the protruding direction of the locking portion 15 to allow the flooring 3 to move downward. The positions of the two protrusions 20 provided on the flooring support 4B are not limited to the above, and they may be located at positions facing the side surface 3a of the flooring 3G. The number of protrusions 20 provided on the flooring support 4B is not limited to two, and may be one, or three or more.

[0068] In this embodiment, a gap g is provided between two adjacent floor materials 3, but it is not necessary to provide the gap g. Even in this case, since the protrusion 12 has flexibility that allows it to elastically deform in the direction opposite to the protruding direction of the locking portion 15, when removing the floor material 3, the floor material 3 can be easily removed by using, for example, a tool having a suction cup that can be attached to the surface of the floor material 3 and a gripping portion that can be gripped.

[0069] In addition, in this embodiment, the flooring support 4 is provided with the claw portion 13, but this is not limited to this. For example, the flooring support 4 may be formed integrally with the upper end of the support leg 5.

[0070] Furthermore, in this embodiment, the floor structure 1 in which the floor material supports 4 are attached to the upper ends of the support legs 5 has been described, but the floor structure is not limited to this.

[0071] Fig. 11 is an explanatory diagram showing a first modified example of the floor structure, where (a) shows the state seen from the direction in which the joists extend, and (b) shows the state seen from the direction intersecting the joists. Fig. 12 is an explanatory diagram showing a second modified example of the floor structure.

[0072] For example, as in the floor structure 1A shown in Fig. 11, a joist 30 extending in a predetermined direction is placed on the support leg 5A, a joist 31 extending in a direction intersecting the predetermined direction is placed on the joist 30, a flooring support 4 is placed at a predetermined position on the joist 31, and a flooring 3 (a long board-shaped flooring 3 in Fig. 11) is attached to the flooring support 4. In this case, the base 11 of the flooring support 4 may be fixed onto the joist 31 without providing the claw portion 13 on the flooring support 4. Although Fig. 11 shows the flooring support 4 having one protrusion 12, the number of protrusions 12 is not limited to this, and the flooring support 4 may have two protrusions 12 as shown in Fig. 9.

[0073] Alternatively, as in the floor structure 1B shown in Fig. 12, a joist 32 extending in a predetermined direction may be placed on the support leg 5B, a floor material support 4 may be placed at a predetermined position on the joist 32, and a floor material 3 (a long board-shaped floor material 3 in Fig. 12) may be attached to the floor material support 4. In this case, the base portion 11 of the floor material support 4 may be fixed onto the joist 32 without providing the claw portion 13 on the floor material support 4.

[0074] In addition, in this embodiment, the floor structure 1 has been described as a double-floor structure in which the floor material 3 is placed above the support legs 5 provided on the floor slab 2, but the present invention is not limited to this, and for example, the floor material support 4 may be used by directly placing it on a base such as the floor slab 2 without providing the support legs 5. In this case, the base part 11 of the floor material support 4 may be placed on the base without providing the claw parts 13 on the floor material support 4.

[0075] Although the present invention has been described based on the above embodiment, the present invention is not limited to the contents of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
