[0003] [Patent Document 1] Japanese Patent Publication No. 2022-12551 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the floor structure described in Patent Document 1 requires a large number of parts and many construction processes, resulting in a long construction period. Furthermore, skilled workers who understand the complex processes are required on-site, making it difficult to install the floor structure. Therefore, when expanding or changing the area of ​​the floor structure from its original state at the time of installation due to changes in life stage or lifestyle, large-scale specialized construction work is required, which is not easy to implement.

[0005] The present disclosure aims to provide a floor module, a floor structure, and a construction method for a floor structure that can be easily installed and that allows for easy area expansion and modification after installation. [Means for solving the problem]

[0006] The present disclosure relates to a floor module, a floor structure, and a construction method for a floor structure, which comprises a plurality of floor panel members arranged in a predetermined direction and connected together to form a floor structure, and a pair of frame members extending in a predetermined direction on the undersides of one end and the other end of the plurality of floor panel members in the extension direction, and connecting the plurality of floor panel members, and in which mounting holes are formed on the undersides of one end and the other end of the frame members in the extension direction for attaching support members that support the floor module.

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0009] In the drawings of this disclosure, four predetermined directions that are perpendicular to one another are represented as the "Fr direction," "Rr direction," "R direction," and "L direction." The "Fr direction" indicates the front direction, the "Rr direction" indicates the back direction of the deck 10, the "R direction" indicates the right direction when viewing the deck 10 from the front, and the "L direction" indicates the left direction when viewing the deck 10 from the front.

[0010] As shown in FIG. 1, the deck 10 has four floor modules 1, adjusters 2, and connecting fittings 7 (not shown). The adjusters 2 are provided on the undersides of the floor modules 1 so as to support the floor modules 1. The connecting fittings 7 are connecting members that connect the floor modules 1 and are not visible on the exterior of the deck 10. The deck 10 allows the combination of floor modules 1 to be freely changed, and can be installed on sites of various shapes or uneven ground. For example, it can be installed on a tiled floor surface such as an apartment balcony, or on soil or grass outdoors. It can also be installed indoors, and can be used as an OA floor, for example.

[0011] The four floor modules 1 are composed of a first floor module 1A, a second floor module 1B, a third floor module 1C, and a fourth floor module 1D. The floor surface of the deck 10 is composed of these four floor modules 1 in a generally rectangular shape in a plan view. However, the number of floor modules 1 is not limited to this, and the shape is not limited to a rectangle.

[0012] As shown in Figures 2 and 3, the first floor module 1A has a plurality of floor panels 11, a pair of frames 12, 12, and a plurality of lid members 13A and 13B. The first floor module 1A is a floor module that is generally rectangular in plan view. The plurality of floor panels 11 are arranged side by side in the extension direction of the frame 12 and form the floor surface of the first floor module 1A. The first floor module 1A is composed of five floor panels 11, but the floor module of the present disclosure is not limited to this. For example, it may be composed of three floor panels, or the floor module may be composed of a combination of floor panels of different sizes.

[0013] The floorboards 11 are made of artificial wood that replicates natural wood. For example, recycled wood made from used wood and plastic can be used. These materials are much lighter than natural wood, which has the advantage that a floor module 1 made up of multiple floorboards 11 can be easily carried by one person. The surface of the floorboards 11 may have a plank-grain texture that imitates natural wood, or may be finished with a decorative sheet or the like. However, the material of the floorboards 11 is not particularly limited, and may be made of natural wood, for example.

[0014] As shown in FIG. 4, the floor panel 11 has an upper surface portion 11a, a lower surface portion 11b, multiple side panels 11c, and multiple hollow portions 111. In FIG. 4, the adjuster 2 is indicated by a two-dot chain line. The upper surface portion 11a and the lower surface portion 11b are paired members and are composed of long, flat plates. The upper surface portion 11a serves as the surface material of the floor panel 11, and the lower surface portion 11b is used for fastening to the adjuster 2. The side panel 11c is a plate material that connects the upper surface portion 11a and the lower surface portion 11b in the vertical direction. Multiple side panels 11c are provided between the upper surface portion 11a and the lower surface portion 11b at regular intervals, forming multiple hollow portions 111. As shown in FIGS. 2 and 3, the floor module 1 is constructed by arranging multiple floor panels 11 in the front-to-rear direction. However, the structure and shape of the floor panel 11 are not particularly limited.

[0015] 2 and 3, the frame 12 has a main body 121 and a pair of end covers 122, 122. The frames 12 are used in pairs and are provided on the undersides of one end and the other end of the floorboards 11 in the extension direction so as to extend in a direction approximately perpendicular to the extension direction of the floorboards 11, and are arranged and fixed to the undersides 11b of the floorboards 11. The floorboards 11 are connected by the pair of frames 12. The main body 121 is a rectangular tubular frame main body, and is made of a shaped member obtained by extruding a metal such as aluminum, for example, but is not limited to this.

[0016] The main body 121 has an upper surface 121a, a lower surface 121b, and side surface portions 121c disposed in the left-right direction. The upper surface 121a and the lower surface 121b have a plurality of through holes FH1 and FH2 along the extension direction of the frame 12. As shown in FIG. 4, the frame 12 is fixed to the floorboard 11 with screws via the through holes FH1 and FH2. The through holes FH2 have a larger diameter than the through holes FH1 and are provided only in the lower surface 121b. As shown in FIG. 4, the frame 12 is fixed to the floorboard 11 by passing the head of a screw through the through holes FH2.

[0017] 2 and 3, the side surface portion 121c has through holes FH3A arranged in pairs next to each other in the vertical direction. The through holes FH3A are provided at both longitudinal ends of the frame 12 and at locations corresponding to the outer periphery of the floor module 1. The through holes FH3A are used when connecting the floor modules 1 together, and the construction method will be described later.

[0018] As shown in Fig. 3, the underside portion 121b has eight first fixing holes AH1. The first fixing holes AH1 are provided on the underside of one end and the other end in the extension direction of the frame 12, and are formed in pairs lined up in directions parallel to each of the four sides of the floor module 1. The first fixing holes AH1 are mounting holes for mounting the adjuster 2 to the floor module 1, and the mounting method will be described later. By configuring the first fixing holes AH1 as multiple mounting holes, it is possible to configure the mounting position of the adjuster 2 relative to the floor module 1 to be changeable.

[0019] As shown in Fig. 2, the end cover 122 is provided to cover the edge of the main body 121 and is fixed to the main body 121 with screws. The end cover 122 may be made of, for example, a resin material, but is not limited to this. The end cover 122 has a pair of through holes FH3B provided in the vertical direction approximately in the center. The through hole FH3B of the end cover 122 and the through hole FH3A of the frame 12 described above have the same shape and are used when connecting floor modules 1 together; the installation method will be described later.

[0020] 2 and 3, lid members 13A and 13B are decorative materials that cover the side surfaces of floorboard 11. Lid members 13A and 13B may be, for example, but are not limited to, resin materials. Lid member 13A is a single long plate, and is provided with an engaging piece (not shown) on the surface facing the outer periphery of floorboard 11, which engages and fixes it in a recess that opens in the extension direction of floorboard 11.

[0021] The lid material 13B is made up of multiple lid materials that cover the edges of the floor board 11, and is provided with engagement pieces (not shown) on the surface facing the outer peripheral surface of the floor board 11, which engage and fix in the hollow portion 111 of the floor board 11. The configuration of the lid material 13A and the lid material 13B is not limited to this, and for example, the multiple lid materials 13B may be made up of long plates, or the lid material 13A may be divided into several parts.

[0022] The second floor module 1B, third floor module 1C, and fourth floor module 1D have the same configuration as the first floor module 1A, so their description will be omitted. As shown in Fig. 1, the first floor module 1A and fourth floor module 1D are arranged so that their floor panels 11 extend in the left-right direction, and the second floor module 1B and third floor module 1C are arranged so that their floor panels 11 extend in the front-to-rear direction. In this way, the floor panels 11 of adjacent floor modules can be arranged orthogonal to each other in a checkerboard pattern.

[0023] With the configuration of the floor module 1 described above, the floor panel 11 and frame 12 are configured as an integrated module, facilitating on-site construction. Furthermore, since multiple mounting holes are formed, the position of the adjuster 2, which will be described later, can be easily determined. Furthermore, the floor module 1 is lightweight, allowing one person to easily lift or carry the floor module 1. This allows the direction of the floor module 1 to be freely determined and floor modules 1 arranged in various directions to be combined, facilitating the positioning and adjustment of the deck, which requires precision and skill, and making construction of the deck 10 extremely simple.

[0024] As shown in Figure 5, the adjuster 2 is a support member made of a head member 21 and a base member 22. The adjuster 2 is made of a weather-resistant resin member, and is lightweight yet suitable for outdoor use. As shown in Figures 6 and 7, the head member 21 and the base member 22 can be separated, and when constructing the deck 10, construction is performed with the two members separated. The head member 21 has a movable plate 211 and a fixed plate 212.

[0025] Eight second fixing holes AH2 are formed on the upper surface of the movable plate 211. The floor module 1 and the adjuster 2 are fixed via the first fixing holes AH1 of the frame 12 and the second fixing holes AH2 of the movable plate 211 described above. The movable plate 211 and the fixed plate 212 can be separated, and when the adjuster 2 is engaged, the second fixing holes AH2 can be completely exposed downward. The method of aligning the frame 12 and the adjuster 2 will be described later.

[0026] As shown in FIG. 7, the fixed plate 212 has a plurality of hook pieces 213 on its underside. The head member 21 is engaged and fixed to the base member 22 via the hook pieces 213. As shown in FIG. 8, the lower surface of the movable plate 211 has a dome-shaped convex portion 211a that protrudes downward, and the upper surface of the fixed plate 212 has a dome-shaped concave portion 212a that opens upward. When the convex portion 211a engages with the concave portion 212a, the movable plate 211 can freely move with the inclination A at its maximum angle. With this configuration, the head member 21 can automatically adjust the inclination A, so that when the deck 10 is installed on a floor surface with a slope equal to or less than the inclination A, the floor module 1 can be automatically kept level. The adjuster 2 has an inclination adjustment mechanism.

[0027] 6, base member 22 has an engagement plate 221, a screw portion 222, a cylindrical portion 223, and a base plate 224. Engagement plate 221 is a plate placed on the upper surface of base member 22 and has a plurality of engagement portions 225. Hook pieces 213 of head member 21 engage with engagement portions 225, thereby reliably fixing head member 21 and base member 22 together. With this configuration, adjuster 2 can be easily constructed by simply inserting hook pieces 213 of head member 21 into engagement portions 225 of base member 22, without using fasteners such as screws.

[0028] The screw portion 222 is a cylindrical member with a helical thread provided on the lower part of the engagement plate 221. The tubular portion 223 and the base plate 224 are integrally molded, and a thread (not shown) is cut inside the tubular portion 223. As shown in FIG. 8, by rotating the engagement plate 221, the screw portion 222 rises upward from the tubular portion 223, allowing the height of the engagement plate 221 to be freely adjusted. With this configuration, the height of the floor module 1 can be adjusted to any height simply by rotating the engagement plate 221. The adjuster 2 has a height adjustment mechanism.

[0029] The adjuster 2 described above makes it very easy to adjust the inclination and height of the floor module 1. With this configuration, it is very easy to level the deck 10 even on an uneven site, and the inclination of the floor module 1 due to a slope is automatically adjusted by the head member 21. Furthermore, even after the deck 10 has been installed, the height of the floor module 1 can be easily adjusted to any height.

[0030] The adjuster 2 only needs to be placed on the floor surface; there is no need to fasten it to the floor surface with fasteners such as screws. This configuration allows the deck 10 to be installed on any floor surface, including porcelain tile floors where drilling is difficult. Furthermore, the installation method for the adjuster 2 is not limited to this; fasteners may be used as needed. For example, the deck 10 can be fixed to the ground surface, such as grass, by driving pegs into the through-holes provided in the base plate 224.

[0031] Next, a method of engaging the floor module 1 with the adjuster 2 will be described. As shown in Fig. 6, two diagonally adjacent through holes of the second fixing holes AH2 provided in the movable plate 211 of the adjuster 2 correspond to the first fixing holes AH1 of the floor module 1 and are used for alignment when engaging the two components. The reference value X is a reference distance used for aligning the floor module 1 and the adjuster 2. Of the pairs of through holes indicated by the four reference values ​​X, any one pair of through holes is used for alignment.

[0032] 9 and 10, the reference value X of two diagonally adjacent through holes of the first fixing hole AH1 provided in the frame 12 of the floor module 1 corresponds to the reference value X of the second fixing hole AH2 of the adjuster 2. Of the pairs of through holes indicated by the four reference values ​​X, any one of the paired through holes is used to align the floor module 1 and the adjuster 2.

[0033] As shown in FIG. 11, the adjuster 2 can be provided in three different positions relative to the floor module 1. In FIG. 11, the floor module 1 is represented by a two-dot chain line. The adjuster 2A is an adjuster that is placed at a corner of the floor module 1. The adjuster 2A is positioned so that its main body is shielded under the floorboard 11, and is placed so that the reference value X of the first fixing hole AH1 and the reference value X of the second fixing hole AH2 overlap. With this configuration, the adjuster 2A is shielded by the floor module 1 in a plan view, improving the design of the deck 10.

[0034] The adjuster 2B is an adjuster that is placed at the connection portion when connecting two floor modules 1. The adjuster 2B is positioned so that approximately half is shielded under the floor panel 11 and the remaining approximately half is exposed from the floor panel 11, and is placed so that the reference value X of the first fixing hole AH1 and the reference value X of the second fixing hole AH2 overlap. The movable plate 211 of the adjuster 2B supports two adjacent connected floor modules 1. With this configuration, one adjuster 2B can support the deck 10 by bearing the load of two adjacent connected floor modules 1. Furthermore, the adjuster 2B is shielded in a plan view by the two connected floor modules 1, improving the design of the deck 10.

[0035] Adjuster 2C is an adjuster that is placed at the center of four floor modules that are connected by butting their corners. Adjuster 2C is positioned so that about one-quarter (1 / 4) is hidden under floor panel 11 and the remaining approximately three-quarters (3 / 4) is exposed from floor panel 11, and is placed so that the reference value X of first fixing hole AH1 and the reference value X of second fixing hole AH2 overlap.

[0036] The movable plate 211 of the adjuster 2C supports the four floor modules 1 that are connected so that their corners butt together. With this configuration, one adjuster 2C can bear the load of the four floor modules 1 that are connected so that their corners butt together, and support the deck 10. Furthermore, the adjuster 2C is shielded in a plan view by the four connected floor modules 1, improving the design of the deck 10.

[0037] As shown in Figure 12, when the deck 10 is assembled, the adjusters 2 are arranged in the three positions described above. In Figure 12, the floor modules 1 are represented by two-dot chain lines. The adjusters 2A arranged in the corners of the first floor module 1A and the adjusters 2A arranged in the corners of the second floor module 1B are arranged symmetrically in the left-right direction, and the adjusters 2A arranged in the corners of the first floor module 1A and the adjusters 2A arranged in the corners of the third floor module 1C are arranged symmetrically in the front-to-rear direction.

[0038] As shown in Figures 6 and 10, the first fixing hole AH1 and the second fixing hole AH2 have paired through holes that are arranged at a reference value X so as to be symmetrical in the front-to-back and left-to-right directions. With this configuration, the deck 10 can be constructed with only one type of adjuster 2. Dedicated adjusters for the corners or connecting parts are not required, and the first floor module 1A can be easily supported by arranging the three types of adjusters 2, regardless of the configuration of the first floor module 1A.

[0039] The floor modules 1A arranged on the deck 10 are connected by connecting fittings 7. The connecting fittings 7 are fittings used when constructing the deck 10 and are not exposed to the outside of the installed deck 10. As shown in FIG. 28A, the connecting fittings 7 are made up of a first connecting fitting 71 and a second connecting fitting 72 and are used as a pair. The first connecting fitting 71 is a sheet metal member formed in a substantially L-shape and has an upper surface portion 711 and a side surface portion 712. The upper surface portion 711 has a fastening hole FH5, and as shown in FIG. 4, the first connecting fitting 71 and the second connecting fitting 72 are connected via a screw SC.

[0040] The side surface portion 712 has an elongated hole and is fixed to the frame 12 of the floor module 1 via a screw. As shown in FIG. 28A, during construction, the top surface portion 711 is connected with a screw SC inserted into the fastening hole FH5. The second connecting fitting 72 is a sheet metal member formed in a substantially L-shape and has a flat surface portion 721 and a side surface portion 722. The flat surface portion 721 has a notch portion 721a, and as shown in FIG. 28B, when the first connecting fitting 71 and the second connecting fitting 72 are connected, a screw SC is inserted into the notch portion 721a.

[0041] With this configuration, the first connecting fitting 71 and the second connecting fitting 72 can be engaged by sliding the connecting fitting 7 horizontally. The side surface portion 722 has a screw hole and is fixed to the frame 12 of the floor module 1 via a screw. The upper surface portion 711 of the first connecting fitting 71 and the flat surface portion 721 of the second connecting fitting 72 are joined and connected, thereby connecting the floor modules 1 to each other; therefore, the first connecting fitting 71 and the second connecting fitting 72 are each attached to floor modules 1 that are arranged adjacent to each other.

[0042] By using the floor modules 1 and adjusters 2 described above and connecting the floor modules 1 together via connecting fittings 7, it is possible to install decks of various configurations, not just the deck 10. For example, as shown in FIG. 13, a larger deck 10B can be constructed using nine floor modules 1. Note that in FIGS. 13 to 16, the floor modules 1 are represented by two-dot chain lines. The deck 10B uses adjusters 2A, 2B, and 2C, and the nine floor modules 1 shield the adjuster 2 in a plan view, improving the design of the deck 10B.

[0043] 14, it is also possible to construct a roughly O-shaped deck 10C with a hollow center. For example, after installing deck 10B, the configuration can be easily changed from deck 10B to deck 10C by simply removing the floor module 1 placed in the center, changing the position of adjuster 2C, and installing an additional adjuster 2. The installation direction of the floor modules 1 is also free, and they may be arranged with the extension direction of the floor panels 11 uniformly aligned, as in deck 10C.

[0044] As shown in Figure 15, it is also possible to configure a deck 10D assembled in a roughly C-shape. For example, after installing deck 10C, the configuration of deck 10C can be easily changed to that of deck 10D by removing a set of floor modules 1 and the adjuster 2 provided at the bottom, and changing the position of adjuster 2B corresponding to the corner portion of floor module 1 to adjuster 2A. Furthermore, the direction in which the floor modules 1 are arranged is free, and the extension directions of the floor boards 11 of adjacent floor modules 1 may be configured to extend in directions roughly perpendicular to each other, like a checkerboard pattern.

[0045] As shown in FIG. 16, a generally L-shaped deck 10E can be constructed using seven floor modules 1. As described above, by using the floor modules 1 and the adjusters 2, decks of various shapes can be constructed by freely combining floor modules 1 on-site without the need for prior design. In particular, even on uneven ground where precision in positioning and leveling is required, the deck 10 can be easily installed without the need for skilled workers. Furthermore, because the deck 10 can be used over time without fixing the adjusters 2 to the ground with fixing devices, the deck configuration can be easily changed even after the deck 10 is installed.

[0046] This configuration allows the deck 10 to be easily installed and the configuration of the deck 10 to be easily changed in accordance with changes in life stages and lifestyles without requiring large-scale specialized construction work.

[0047] Next, we will explain the dedicated accessories used with the deck 10. These accessories can be easily attached and removed even after the deck 10 has been installed. By using these accessories, the usability of the deck 10 can be improved and the space can be easily configured for activities tailored to the intended use.

[0048] As shown in Figures 17 and 18, a dedicated panel 3 can be provided on the deck 10. The panel 3 has a pair of side panels 31 and a cover material 32. The panel 3 is made of a shaped material obtained by extruding a metal such as aluminum, but is not limited to this. The cover material 32 is bent at a substantially right angle into a substantially L-shape, and has the effect of blocking views from the side and below. Side panels 31 are provided at both longitudinal ends of the cover material 32.

[0049] As shown in Figure 25, the header panel 3 is arranged along the outer periphery of the deck 10 so as to cover the frame 12 of the floor module 1. The cover material 32 provides a concealing effect by shielding the lower part of the floor module 1, and by hiding part of the adjuster 2, it is possible to improve the design of the deck 10. The header panel 3 may be fixed to the frame 12 with screws, or may be attached via a magnet or adhesive.

[0050] As shown in Figures 19 and 20, the fence 4 is an accessory that is approximately L-shaped in plan view and can be installed on the deck 10 as a fall prevention fence. The fence 4 has an upper frame 41, a lid 42, and multiple legs 43. As shown in Figure 21, the upper frame 41 is formed in a cylindrical shape that is concave downward, and has a groove 411 in the center of the lower surface. The upper frame 41 is made of a shaped member obtained by extruding a metal such as aluminum, for example, but is not limited to this.

[0051] The groove 411 has a hook at its end, allowing for the attachment of a line light or the like equipped with an LED light source. The lid 42 has an engagement piece 421 at its tip that engages with the upper frame 41, allowing for the lid 42 to cover the lower part of the upper frame 41 from below. The lid 42 is formed, for example, from a translucent resin material. With this configuration, the upper frame 41 can be installed on the deck 10 as indirect lighting that illuminates downward.

[0052] A plurality of legs 43 are provided to support the upper frame 41, and have through holes FH4 on the bottom surface. The fence 4 is placed on the floor module 1 by fastening with screws via the FH4. As shown in FIG. 25, the fence 4 may be installed at the corners of the deck 10. The size of the fence 4 is not limited to this; for example, the upper frame 41 may be made longer and the number of legs 43 may be increased to match the size of the deck. The shape of the fence is also not particularly limited, and may be a shape other than an L-shape.

[0053] 22 and 23, the bench 5 has a seat 51 and a pair of legs 52. The seat 51 may be made of the same material as the floor board 11 of the floor module 1, and by creating a sense of unity between the bench 5 and the floor module 1, the design of the deck 10 can be improved. The legs 52 are configured in a roughly O-shape and are made of a shaped member obtained by extruding a metal such as aluminum, for example, but are not limited to this.

[0054] A sense of unity can be achieved by constructing the legs 52 of the bench 5 and the upper frame 41 and legs 43 of the fence 4 from the same material and applying the same finish. For example, by applying a hairline finish to the legs 52 of the bench 5 and the upper frame 41 and legs 43 of the fence 4, the accessories can be made to look unified, improving the design of the deck 10. As shown in FIG. 25 , the bench 5 can be installed at any position on the floor module 1 and may be fixed to the floor module 1 with screws or adhesive, for example.

[0055] As shown in FIG. 24, the box 6 is a rectangular cylindrical accessory. As shown in FIG. 25, the box 6 can be installed on the floor module 1 in any direction. The surface of the box 6 may be made of the same material as the floorboards 11 of the floor module 1, and by creating a sense of unity with the bench 5 and floor module 1 described above, the design of the deck 10 can be improved. The box 6 can be used as a chair or table, or as a storage box. In addition, the hollow space can be decorated with a potted plant and used as a planter. Multiple boxes 6 can be used in combination with other ideas.

[0056] The present disclosure is not limited to the above-described embodiments and can be modified as appropriate.

[0057] For example, an LED light source can be installed in the gap between adjacent floor modules 1. As shown in Fig. 4, a gap Y is provided between the floor modules 1, and indirect lighting can be installed below the floor modules 1 so that indirect light is irradiated from this gap Y. As described above, the fence 4 can also be used as indirect lighting, so the deck 10 can be decorated with lighting in combination with the fence 4.

[0058] This allows the deck 10 to be used not only during the day but also for nighttime activities. For example, by placing a camping tarp next to the deck 10, it is possible to enjoy outdoor life. The floor module 1 can be easily installed on the site, and the configuration can be easily changed and the floor module 1 can be easily removed, which has the effect of improving the usability of the deck 10 and allowing the deck 10 to be used flexibly.

[0059] Furthermore, the connectors that connect the floor modules 1 together are not limited to the connecting fittings 7. For example, magnets may be provided on the frame 12, and the floor modules 1 may be connected together via the magnets. With this configuration, floor modules 1 can be easily connected together without the need for tools, and decks of various configurations can be installed.

[0060] Furthermore, the adjuster 2 does not have to be equipped with a height adjustment mechanism or a tilt adjustment mechanism, or may be equipped with only one of them. The support members used in the present disclosure may have any configuration as long as they are support members that can support the floor module 1, and for example, the deck 10 may be constructed using a cylindrical molded material.

[0061] Furthermore, the number of frames 12 provided on a floor module 1 is not limited to two. As shown in FIG. 31, a deck may be constructed using floor modules 1B in which frames are provided in four directions. In FIG. 31, the floor boards 11 are represented by two-dot chain lines. The floor module 1B comprises the floor boards 11 and four frames 12B arranged along the outer periphery of the floor module 1B. The frames 12B are connected by four corner members 13. For example, when a high load is applied to the floor module during use, a deck can be constructed using floor modules 1B.

[0062] Next, a method for constructing the deck 10 will be described. First, the first floor module 1A is constructed, and then the floor modules are connected in the order of the second floor module 1B, the third floor module 1C, and the fourth floor module 1D to form the deck 10. As shown in Figure 26, first, the adjuster 2 is attached to the frame 12 of the first floor module 1A. The adjuster 2 is separated into a head member 21 and a base member 22, and the four head members 21 are attached to the underside portion 121b of the frame 12.

[0063] 11, the adjusters 2 are arranged at three different positions relative to the floor module 1 by aligning the positions of the second fixing holes AH2 of the four head members 21 with the first fixing holes AH1 provided in four locations on the frame 12, and then fixing the head members 21 to the underside 121b of the frame 12 with screws. When fixing the head members 21, the installation work may be performed with the floor module 1 upside down, or it may be performed by tilting it against a wall or the like so that the frame 12 is exposed. The floor module 1 is very lightweight and can be easily lifted and rotated by one person, improving the work efficiency of the deck 10.

[0064] After the four head members 21 are fixed to the correct first fixing holes AH1 of the frame 12, the base members 22 of the adjusters 2 are then engaged with the head members 21. The hook pieces 213 of the head members 21 are inserted into the engagement portions 225 of the base members 22 to ensure a secure engagement. This allows the adjusters 2 to be easily attached to the first floor module 1A without using any tools. Through the above-described procedure, three types of adjusters 2, adjuster 2A, adjuster 2B, and adjuster 2C, are fixed to the first floor module 1A.

[0065] Unlike conventional deck construction, there is no need to first fix the base member 22 to the site, and the adjuster 2 automatically adjusts the tilt and can freely adjust the level to any height, so there is no need for precise leveling or positioning work on the site where the deck 10 will be installed. This configuration reduces the number of steps required for construction, and even beginners can easily install the deck 10.

[0066] As shown in Figure 27, the first floor module 1A equipped with four adjusters 2 is placed where the deck 10 is to be installed. In Figure 27, the first floor module 1A and the second floor module 1B are represented by two-dot chain lines. The floor module 1 is very lightweight and can be easily lifted and rotated by one person, allowing the first floor module 1A to be installed anywhere. Next, the first floor module 1A placed on the installation surface is leveled using a level (not shown). If necessary, the engagement plate 221 of the adjuster 2 is rotated to adjust the height of the adjuster 2 to the desired height.

[0067] Once the level adjustment of the first floor module 1A is complete, the adjuster 2 is then attached to the frame 12 of the second floor module 1B. As shown in Figure 12, the second floor module 1B requires only the adjuster 2A and adjuster 2B to be placed at the R-direction end. The method of attaching the adjuster 2 is the same as that for the first floor module 1A, so a description thereof will be omitted.

[0068] Next, as shown in Figure 27, the connecting fittings 7 are attached to the first floor module 1A and the second floor module 1B. First, the side surface portion 712 of the first connecting fitting 71 is fixed with a screw to the through hole FH3A provided in the frame 12 of the first floor module 1A. The through holes FH3A are a pair of vertically aligned through holes, and the screw is inserted into the lower hole to secure the first floor module 1A. Next, the side surface portion 722 of the second connecting fitting 72 is fixed with a screw to the through hole FH3B provided in the frame 12 of the second floor module 1B. The through hole FH3B is a pair of vertically aligned through holes, and the screw is inserted into the upper hole to secure the first floor module 1A.

[0069] As shown in FIG. 4 , the first connecting fitting 71 and the second connecting fitting 72 attached to the frame 12 are positioned at a height where the top surface 711 of the first connecting fitting 71 and the flat surface 721 of the second connecting fitting 72 join together. Because the through-holes FH3A and FH3B are paired through-holes in the vertical direction, either the first connecting fitting 71 or the second connecting fitting 72 can be fastened. Furthermore, because the side surface portion 121c of the frame 12 is provided with the through-hole FH3A and the end covers 122 provided on both ends of the frame 12 are provided with the through-hole FH3B, the connecting fittings 7 can be attached to all four sides that form the periphery of the floor module 1. Note that there are no particular limitations on the method of fastening the connecting fittings 7 to the frame 12.

[0070] With this configuration, all four sides of the floor module 1 that form the periphery of the floor module 1 can be connected together using the connecting fittings 7. Therefore, there is no need to prepare multiple floor modules for each placement location, and multiple floor modules 1 can be arranged in any direction using just one type of floor module 1, allowing the deck to be freely configured. Furthermore, because the connecting fittings 7 and adjusters 2 are common parts, the number of types of component parts can be reduced. This makes construction of the deck 10 extremely easy, and even beginners can easily connect the floor modules 1 together, reducing the amount of work required.

[0071] As shown in Figure 27, the second floor module 1B, to which the connecting fitting 7 is attached, is slid in the direction of the arrow to connect it to the first floor module 1A. As shown in Figures 28A and 28B, a screw SC is inserted beforehand into the fastening hole FH5 of the first connecting fitting 71. As a result, when the second floor module 1B slides in the direction of the arrow, the notch 721a of the second connecting fitting 72 engages with the screw SC. Once the position of the connecting fitting 7 has been determined, as shown in Figure 4, a tool such as a screwdriver is inserted through the gap Y between the floor modules 1 and the screw SC is further tightened from above, thereby securely tightening the connecting fittings 7 together and fixing them in place.

[0072] With this configuration, workers can fasten the connecting fittings 7 together from above the floor modules 1 to be connected. Connecting the floor modules 1 does not require a large work space, and the deck 10 can be easily installed even in places where there is not enough work space, such as a veranda surrounded on three sides by handrails, etc. Furthermore, since the floor modules 1 can be connected with just a screwdriver, even beginners can easily connect the floor modules 1 together.

[0073] After the first floor module 1A and the second floor module 1B are connected, the level is adjusted again using a level (not shown). The level adjustment is the same as the level adjustment of the first floor module 1A described above, so a description thereof will be omitted.

[0074] Next, as shown in FIG. 29, the third floor module 1C is connected to the first floor module 1A. First, the adjuster 2 is attached to the frame 12 of the third floor module 1C. However, since the attachment method is the same as that of the first floor module 1A and the second floor module 1B described above, a description thereof will be omitted. The adjuster 2A and the adjuster 2B are fixed to the third floor module 1C. Next, the connecting fittings 7 are attached to the frame 12. A first connecting fitting 71 is fixed via a screw to the lower section of the through hole FH3B of the first floor module 1A. Furthermore, a second connecting fitting 72 is fixed via a screw to the upper section of the through hole FH3A of the third floor module 1C. The method of fixing each connecting fitting and the method of connecting the connecting fitting 7 are the same as the construction method of the first floor module 1A and the second floor module 1B described above, and therefore a description thereof will be omitted.

[0075] Finally, the fourth floor module 1D is connected to the second floor module 1B and the third floor module 1C, completing the connection work. After the deck 10 is constructed, a final leveling adjustment is performed using a level (not shown). This leveling adjustment is the same as the leveling adjustment of the first floor module 1A described above, so a detailed explanation will be omitted. As shown in Figure 30, the four floor modules 1 can be securely connected using the connecting fittings 7.

[0076] According to the construction method for the deck 10 described above, the number of steps can be reduced and the deck 10 can be easily assembled. Furthermore, the floor modules 1, adjusters 2, and connecting fittings 7 are all made of a single type of component with a set standard, so even beginners can easily understand the construction method. Furthermore, unlike conventional deck construction methods, precise positioning and leveling work is not required to secure the deck foundation to the floor surface, and the skills of a skilled worker are not required. According to the construction method for the deck 10, the level can be easily adjusted using the adjusters 2 while the floor modules 1 are being connected.

[0077] Furthermore, in conventional deck construction methods, when connecting multiple floor components that make up the floor, the skill of aligning the joint widths uniformly is required in order to maintain aesthetic appeal. However, according to the construction method of deck 10, by using floor modules 1 and connecting fittings 7, even beginners can easily align the joints of the floor components and connect the floor modules 1 together. This makes it possible to easily construct a deck with excellent design, even without the skills of a skilled craftsman.

[0078] By using the construction method of the deck 10, the floor modules 1 can be easily connected to each other or detached. This makes it easy to change the configuration of a deck once it has been constructed. Since it is also easy to add standardized floor modules 1, the deck configuration can be flexibly changed to suit your lifestyle.

[0079] The present disclosure is not limited to the above-described embodiments and can be modified as appropriate.

[0080] For example, the location on the deck where the adjuster 2 is placed is not limited to the location in this embodiment. The adjuster 2 can be placed freely, and additional adjusters 2 can be added, depending on the usage situation. Furthermore, the placement locations of the first connecting fitting 71 and the second connecting fitting 72 of the connecting fitting 7 are also not limited to the locations in this embodiment. The first connecting fitting 71 and the second connecting fitting 72 only need to be able to reliably fasten the floor modules 1 together as a pair of connecting fittings, and for example, the fastening locations of the first connecting fitting 71 and the second connecting fitting 72 may be interchanged.

[0081] Furthermore, the order in which the first floor module 1A, second floor module 1B, third floor module 1C, and fourth floor module 1D are installed is not limited to the order in this embodiment. As long as the above-mentioned installation procedure is observed and the floor modules 1 are reliably connected to each other, installation work may begin with any floor module 1. Depending on the installation location, installation may begin with the third floor module 1C, for example.
