Description

[Technical Field]

[0001] The present invention particularly relates to an improvement in a floor structure in which floor panels are attached to support legs in a double floor structure. [Background technology]

[0002] There are two types of floor structures for buildings: a direct floor structure in which floor panels are laid directly on the foundation slab, and a double floor structure in which floor panels are placed at a distance from the foundation slab, creating a space between the floor panels and the foundation slab. A double floor structure has multiple vibration-isolating support legs placed on a foundation slab, and these vibration-isolating support legs support floor panels.The space between the foundation slab and the floor panels insulates floor impact noise, and this space can also be used as piping space, so an increasing number of buildings are adopting double floor structures. Patent Document 1 shows a conventional method for attaching floor panels to a double floor structure. According to this conventional attachment method, as shown in Figure 12, the corners of four floor panels 35, 39, 40, and 41 are placed on a panel receiving bracket 34 attached to one support leg 33, and these floor panels are then fixed to the panel receiving bracket 34 from above using wood screws 47, 52, 53, and 54 via connecting brackets 48.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-146544 Summary of the Invention [Problem to be solved by the invention]

[0004] According to the conventional floor panel mounting method described above, the corners of the four floor panels 35, 39, 40, and 41 can be supported by one support leg 33, which has the effect of reducing the number of support legs 33 overall.In addition, since the four floor panels are configured to be fixed from above with wood screws via connecting fittings 48, installation is easy. However, the conventional floor panel mounting method described above uses wood screws to secure the floor panels from above, which means that the heads of the screws are visible on the surface of the floor panels after they are secured, detracting from the overall appearance of the floor. Furthermore, since the panels are secured from above with wood screws via connecting metal fittings 48, all four floor panels must be placed on the panel receiving metal fittings 34 of the support legs 33 before being secured with wood screws, which makes installation difficult. The present invention aims to solve the above-mentioned conventional problems and to provide a floor structure that does not require the use of members such as wood screws to fix floor panels, and that allows floor panels to be easily fixed to support legs one by one. [Means for solving the problem]

[0005] In order to achieve the above-mentioned object, the floor structure of the present invention is a floor structure consisting of a plurality of support legs and rectangular floor panels whose corners are placed and supported by each of the support legs, wherein a concave or convex portion is provided on the bottom surface of the corner of the rectangular floor panel, and a convex or concave portion is provided on the upper surface of the support leg that can fit into the concave or convex portion of the rectangular floor panel, so that when the corner of the rectangular floor panel is placed on the upper surface of the support leg, the concave or convex portion provided on the rectangular floor panel fits into the convex or concave portion provided on the support leg, and the rectangular floor panel is fixed to the support leg. In the above-mentioned floor structure, the support leg may be provided with a plate-shaped panel receiving portion made of a non-magnetic material, and the rectangular floor panel may be provided with a convex or concave portion that can fit into the concave or convex portion of the rectangular floor panel, so that when the corner of the rectangular floor panel is placed on the upper surface of the support leg, the concave or convex portion of the rectangular floor panel and the convex or concave portion of the plate-shaped panel receiving portion provided on the support leg fit together, thereby fixing the rectangular floor panel to the support leg. In this case, the plate-shaped panel receiving portion may be provided with four fixing plate pieces that protrude upward from the upper surface thereof and are arranged at 90-degree angles to one another. Furthermore, preferably, the plate-shaped panel receiving portion is provided with at least a pair of fixing claw portions extending downward from its bottom surface, and the pair of fixing claw portions clamp the support leg to fix the plate-shaped panel receiving portion to the support leg. [Effects of the Invention]

[0006] According to the floor structure of the present invention, the floor structure consists of a plurality of support legs and rectangular floor panels whose corners are placed on and supported by each of the support legs, and the rectangular floor panels have concave or convex portions on the bottom surfaces of the corners, and the support legs have convex or concave portions on the upper surfaces thereof that can fit into the concave or convex portions of the rectangular floor panel, so that when the corners of the rectangular floor panel are placed on the upper surfaces of the support legs, the concave or convex portions on the rectangular floor panel fit into the convex or concave portions on the support legs, and the rectangular floor panel is fixed to the support legs.This makes it possible to fix the floor panels and support legs without using connecting members such as wood screws or screws, and as a result, the floor panels can be easily attached and detached to the support legs, and the connecting members such as wood screws or screws will not be visible on the surface of the floor panel, which will spoil the appearance of the floor. In addition, in the floor structure, the support legs are provided with plate-shaped panel receiving portions made of a non-magnetic material, and the rectangular floor panel is provided with convex or concave portions that can fit into concave or convex portions of the rectangular floor panel, so that when the corners of the rectangular floor panel are placed on the top surface of the support legs, the concave or convex portions of the rectangular floor panel and the convex or concave portions of the plate-shaped panel receiving portions of the support legs fit together, and the rectangular floor panel is fixed to the support legs.This eliminates the need for the support legs to have a special structure, and by providing separate plate-shaped panel receiving portions, it can be easily applied to floor structures that use existing support legs. Furthermore, by providing the plate-shaped panel receiving portion with four fixed plate pieces arranged at 90-degree angles to each other and protruding upward from its upper surface, it becomes possible to position the floor panel using the fixed plate pieces, making it easier to position the floor panel, and furthermore, the fixed plate pieces can prevent the floor panel from shifting during use. Furthermore, by providing the plate-shaped panel receiving portion with at least a pair of fixing claws extending downward from its bottom surface and configuring the pair of fixing claws to clamp the support leg and fix the plate-shaped panel receiving portion to the support leg, it becomes possible to easily fix the plate-shaped panel receiving portion to the support leg without using connecting members or tools such as screws, thereby achieving the effect of facilitating installation.

[0008] Hereinafter, an embodiment of a floor structure according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic partial side view showing an embodiment of a floor structure according to the present invention. According to the floor structure of the embodiment shown in Figure 1, multiple support legs 2 are erected on a foundation surface 1, and corners 21 of rectangular floor panels 20 are placed and supported on the upper support plates 3 of the support legs 2 via plate-shaped panel receiving portions 10. FIG. 2 is a top view of an embodiment of the plate-shaped panel receiving portion 10 used in the floor structure shown in FIG. 1, and FIG. 3 is a cross-sectional view taken along line AA of the plate-shaped panel receiving portion 2 shown in FIG. As shown in the drawings, in this embodiment, the plate-shaped panel receiving portion 10 is formed of a square plate when viewed from above, and is made of a non-magnetic material, for example, a resin material. The plate-shaped panel receiving portion 10 has four fixed plate pieces 11 arranged at 90-degree angles to each other and protruding upward from its upper surface, and is configured so that a corner 21 of a rectangular floor panel 20 is placed between two of the fixed plate pieces 11. A through hole 12 with a circular cross section is formed between the two fixed plate pieces 11 of the plate-shaped panel receiving portion 10, and when the plate-shaped panel receiving portion 10 is fixed to the upper support plate 3 of the support leg 2, the bottom opening of the through hole 12 is blocked by the upper surface of the upper support plate 3, thereby forming a recess 14. Furthermore, a plurality of fixing claws 13 projecting downward from the bottom surface are integrally formed on the bottom surface of the plate-shaped panel receiving portion 10. The fixing claws 13 are formed in pairs along opposing side surfaces of the plate-shaped panel receiving portion 10, and are configured to sandwich the upper support plate 3 of the support leg 2 between the pair of fixing claws 13 and fix the plate-shaped panel receiving portion 10 to the upper support plate 3 of the support leg 2. In this embodiment, four pairs of fixing claws 13 are formed.

[0009] FIG. 4 is a top view of an embodiment of a rectangular floor panel 20 used in the floor structure shown in FIG. 1, and FIG. 5 is a front view of the rectangular floor panel 20 shown in FIG. As shown in the drawings, a rectangular floor panel 20 has convex portions 22 formed on the bottom surface of each of its four corners 21, which convex portions 22 protrude downward. The protrusion 22 has a shape and dimensions corresponding to the recess 14 formed in the plate-like panel receiving portion 10 described above, and is formed so as to fit into the recess 14 .

[0010] 6 to 8 are diagrams showing the process of fixing the plate-shaped panel receiving portion 10 to the support leg 2 erected on the base surface 1, and then placing and supporting the rectangular floor panel 20. FIG. As shown in Figure 6, the support leg 2 erected on the base surface 1 consists of an upper support plate 3, a height adjustment member 4 fixed to the upper support plate 3, and a base part 5 to which the height adjustment member 4 is attached so that it can be adjusted in the vertical direction. The plate-shaped panel receiving portion 10 is fixed to the upper support plate 3 of the support leg 2 using the fixing claws 13 (see FIG. 7). As described above, in this embodiment, four pairs of fixing claws 13 are formed on the plate-shaped panel receiving portion 10, and as shown in FIG. 7, the plate-shaped panel receiving portion 10 is attached to the upper support plate 3 so that the upper support plate 3 is sandwiched between the pairs of fixing claws 13. Furthermore, with the plate-shaped panel receiving portion 10 attached to the support leg 2, the bottom surface of the through hole 12 formed in the plate-shaped panel receiving portion 10 is closed by the upper support plate 3, and a recess 14 is formed. After fixing the plate-shaped panel receiving portion 10 to the upper support plate 3 of the support leg 2, when the rectangular floor panel 20 is placed on the plate-shaped panel receiving portion 10 so that the side of its corner 21 contacts the fixed plate piece 11 of the plate-shaped panel receiving portion 10, each of the convex portions 22 of the rectangular floor panel 20 fits into the concave portion 14 formed in the plate-shaped panel receiving portion 10, and the rectangular floor panel 20 is fixed to the support leg 2.

[0011] In the above-described embodiment, a through hole 12 is provided in the support leg 2, i.e., the plate-shaped panel receiving portion 10 fixed to the upper support plate 3 of the support leg 2, and a recess 14 is formed in the through hole 12, a protrusion 22 is formed in the rectangular floor panel 20, and the rectangular floor panel 20 is fixed to the support leg 2 and placed and supported by fitting the protrusion 22 into the recess 14. However, the configuration of the recess and protrusion is not limited to this embodiment, and for example, a configuration may be adopted in which a protrusion is formed on the support leg 2 side and a recess is formed on the bottom surface of the rectangular floor panel 20. In this embodiment, the recess 14 is formed by providing the plate-shaped panel receiving portion 10 on the support leg 2. However, this configuration is not limited to this embodiment. For example, as shown in FIG. 9, donut-shaped protrusion-forming members 6 are fixed with screws 7 to the four corners of the upper support plate 3 of the support leg 2 to form convex portions 8, and recesses 23 of a shape and dimensions corresponding to the convex portions 8 are formed on the bottom surface of the corners 21 of the rectangular floor panel 20. When the rectangular floor panel 20 is placed on the upper support plate 3, the convex portions 8 formed on the upper support plate 3 fit into the concave portions 23 formed on the rectangular floor panel 20, thereby fixing the rectangular floor panel 20 to the support leg 2. This configuration makes it possible to reduce the number of parts. Note that FIG. 9 is an assembly diagram corresponding to FIGS. 6 to 8 showing a second embodiment of the floor structure according to the present invention. Components identical to or corresponding to those in the first embodiment are designated by the same reference numerals as in the first embodiment. [Explanation of symbols]
