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. [Prior art documents] [Patent documents]

[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 a rectangular floor panel whose corners are placed and supported by each of the support legs, and is characterized in that magnets or magnetic materials are provided on the bottom surfaces of the corners of the rectangular floor panel, and magnetic materials or magnets are provided on the upper surfaces of the support legs, so that when the corners of the rectangular floor panel are placed on the upper surfaces of the support legs, the magnets or magnetic materials provided on the rectangular floor panel come into contact with the magnetic materials or magnets provided on the support legs, and the rectangular floor panel and the support legs are fixed together by the Coulomb force. A convex or concave portion may be formed by a magnet or magnetic material provided on the rectangular floor panel, and a concave or convex portion may be formed by a magnetic material or magnet provided on the support leg, into which the convex or concave portion of the rectangular floor panel can be fitted. Alternatively, the support legs may be provided with plate-shaped panel support parts made of a non-magnetic material, the rectangular floor panel may have a convex part formed of a magnet or magnetic material, the plate-shaped panel support part may have a concave part formed in which the convex part of the front rectangular floor panel can fit, and the magnetic material or magnet may be provided in the concave part. In this case, the plate-shaped panel support part may also have four fixed plate pieces arranged at 90-degree angles to each other and protruding upward from its top surface. Furthermore, the magnetic material or magnet provided on the support leg may be formed as a donut-shaped magnetic material or magnet with a through hole in the center, and the magnetic material or magnet may be fixed to the support leg with a screw through the through hole. [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 magnets or magnetic materials are provided on the bottom surfaces of the corners of the rectangular floor panels, and magnetic materials or magnets are provided on the upper surfaces of the support legs.When the corners of the rectangular floor panel are placed on the upper surfaces of the support legs, the magnets or magnetic materials provided on the rectangular floor panel come into contact with the magnetic materials or magnets provided on the support legs, and the rectangular floor panel and the support legs are fixed together by the Coulomb force.This makes it possible to fix the floor panel and the support legs without using connecting members such as wood screws or screws.As a result, the floor panel 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. By forming convex or concave portions with magnets or magnetic materials attached to the rectangular floor panel, and by using magnetic materials or magnets attached to the support legs to form concave or convex portions into which the convex or concave portions of the rectangular floor panel can fit, the floor panel and support legs are fixed not only by Coulomb force but also by the fitting of the convex and concave portions, thereby increasing the fixing strength between the floor panel and support legs, and further achieving the effect of accurate positioning by fixing the floor panel and support legs by fitting the convex and concave portions together. Furthermore, by providing a plate-shaped panel receiving portion made of a non-magnetic material on the support leg, forming a convex portion using a magnet or magnetic material provided on the rectangular floor panel, forming a concave portion in the plate-shaped panel receiving portion into which the convex portion of the front rectangular floor panel can fit, and providing a magnetic material or magnet in the concave portion, there is no need for the support leg to have a special structure, and by providing a plate-shaped panel receiving portion separately, 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 forming the magnetic material or magnet attached to the support leg as a donut-shaped magnetic material or magnet with a through hole in the center and fixing the magnetic material or magnet to the support leg with a screw via the through hole, it becomes possible to easily attach the magnetic material or magnet to the support leg.

[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. Between the two fixed plate pieces 11 of the plate-shaped panel receiving portion 10, a through hole 12 with a circular cross section is formed, and when the plate-shaped panel receiving portion 10 is fixed to the upper support plate 3 of the support leg 2, a magnet 15 described later can be inserted into each through hole 12. In addition, a fixing claw portion 13 that protrudes downward from the bottom surface is integrally formed on the bottom surface of the plate-shaped panel receiving portion 10, and the fixing claw portion 13 can be used to fix the plate-shaped panel receiving portion 10 to the upper support plate 3 of the support leg 2. The plate-shaped panel receiving portion 10 constructed as described above is fixed to the upper support plate 3 of the support leg 2 together with the magnet 15, and is used to support a rectangular floor panel 20 thereon.

[0009] 4 to 8 are diagrams showing the process of fixing the magnet 15 and 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 4, 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 magnet 15 is a doughnut-shaped cylindrical magnet with a through hole in the center, and is fixed to the upper support plate 3 of the support leg 2 using a screw 16 (see FIG. 5). After the magnet 15 is fixed to the upper support plate 3 of the support leg 2, the plate-shaped panel receiving part 10 is fixed to the upper support plate 3 of the support leg 2 using the fixing claw part 13 (see FIG. 6). As shown in FIG. 6, when the plate-shaped panel receiving part 10 is fixed to the upper support plate 3, the magnet 15 fixed to the upper support plate 3 is inserted into the through-hole 12 of the plate-shaped panel receiving part 10. Here, as is clear from Figures 4 to 8, the thickness h1 of the magnet 15 is thinner than the thickness h2 of the plate-shaped panel receiving portion 10, so that when the plate-shaped panel receiving portion 10 is fixed to the upper support plate 11 so that the magnet 15 is inserted into the through hole 12 of the plate-shaped panel receiving portion 10, the space above the through hole 2 of the plate-shaped panel receiving portion 10 forms a cylindrical recess 14 with the magnet 15 provided on the bottom surface. On the other hand, as shown in Figures 7 and 8, each corner 21 of the bottom surface of the rectangular floor panel 20 has a cylindrical protrusion 22 made of a magnetic material of a shape and size that can fit into the recess 14 of the plate-shaped panel receiving part 10. When the rectangular floor panel 20 is placed on the plate-shaped panel receiving part 10 so that the side of the corner 21 contacts the fixed plate piece 11 of the plate-shaped panel receiving part 10, each of the protrusions 22 of the rectangular floor panel 20 fits into the recess 14 formed in the plate-shaped panel receiving part 10, and the protrusion 22 made of a magnetic material comes into contact with the magnet 15 arranged on the bottom surface of the recess 14, and the rectangular floor panel 20 is fixed to the support leg 2 by the Coulomb force between the two.

[0010] In the above-described embodiment, the magnet 15 is fixed to the upper support plate 3 of the support leg 2 with the screw 16, and the plate panel receiver 10 is fixed to the upper support plate 3 so that the magnet 15 is inserted into the through-hole 12 of the plate panel receiver 10, thereby forming the recess 14 equipped with the magnet in the plate panel receiver 10. However, this configuration is not limited to this embodiment. For example, as shown in Fig. 9, a configuration may be adopted in which the plate panel receiver 10 made of a non-magnetic material is previously formed with a recess 14 that opens upward, the magnet 15 is provided in the recess 14, and the plate panel receiver 10 is fixed to the upper support plate 3 by simply placing the plate panel receiver 10 on the upper support plate 3 of the support leg 2 due to the Coulomb force between the upper support plate 3 made of a magnetic material and the magnet 15 provided in the recess 14. Note that Fig. 9 is a view corresponding to Fig. 8 showing a second embodiment of the floor structure according to the present invention, and the same or corresponding components are designated by the same reference numerals as in the first embodiment. By configuring it in this way, there is no need to provide a fixing claw portion 13 on the plate-shaped panel receiving portion 10, so the configuration of the plate-shaped panel receiving portion 10 is simplified and the method of fixing the plate-shaped panel receiving portion 10 to the support leg 2 is also simplified.

[0011] Furthermore, in the first and second embodiments described above, a recess 15 having a magnet 15 is provided on the support leg 2 side, a protrusion 22 made of a magnetic material is formed on the floor panel 20 side, and the protrusion 22 is fitted into the recess 15, thereby bringing the magnet 15 into contact with the magnetic material. However, this configuration is not limited to this embodiment, and a protrusion having a magnet may be provided on the support leg 2 side, and a recess made of a magnetic material may be provided on the floor panel side, or a recess or protrusion made of a magnetic material may be provided on the support leg 2 side, and a protrusion or recess having a magnet may be provided on the floor panel 20 side. In the first and second embodiments described above, a recess 15 having a magnet 15 is provided on the support leg 2 side, a protrusion 22 made of a magnetic material is formed on the floor panel 20 side, and the protrusion 22 is fitted into the recess 15, thereby allowing the magnet 15 to come into contact with the magnetic material. However, this configuration is not limited to this embodiment. For example, as shown in Fig. 10, a magnet 15 may be provided on the support leg 2 side, or in the embodiment of Fig. 10, on the plate-shaped panel receiver 10 so as to be flush with its upper surface, and a magnetic material portion 23 may be formed on the bottom of the corner of the floor panel 20 so as to be flush with the bottom surface of the floor panel 20, so that when the floor panel 20 is placed on the plate-shaped panel receiver 10, the magnet 15 provided on the plate-shaped panel receiver 10 and the magnetic material portion 23 formed on the floor panel 20 come into contact, and the Coulomb force between them secures the floor panel 20 to the support leg 2. Fig. 10 is a view corresponding to Fig. 8 showing a third embodiment of the floor structure according to the present invention, and the same or corresponding components are designated by the same reference numerals as in the first embodiment. With this configuration, when placing the floor panel 20 on the support leg 2, it is no longer necessary to fit the convex portion into the concave portion, so that the floor panel 20 can be easily attached and detached.

[0012] Furthermore, in the above-described embodiment, the floor panel 20 is attached to the support leg 2 via the plate-shaped panel support portion 10. However, this configuration is not limited to this embodiment. For example, as shown in FIG. 11 , a magnet 15 may be fixed to the upper support plate 3 of the support leg 2 using a screw 16, and a magnetic portion 25 with a recess 24 into which the magnet 15 can fit may be provided on the bottom corner of the floor panel 20. The floor panel 20 may be placed directly on the upper support plate 3 so that the magnet 15 fits into the recess 24, without using the plate-shaped panel support portion 10. The Coulomb force between the magnet 15 and the magnetic recess 24 secures the floor panel 20 to the support leg 2. Note that FIG. 11 corresponds to FIG. 8 , which shows a fourth embodiment of the floor structure according to the present invention. The same or corresponding components are designated by the same reference numerals as in the first embodiment. This configuration eliminates the need for a separate plate-shaped panel support portion 10, thereby reducing the number of parts and simplifying the structure. [Explanation of symbols]
