Description

  The present invention relates to a stone-laminated floor panel used when a floor of a commercial facility or the like is made into a double floor.

  Even with a double floor, a stone-pasted floor panel in which stones are pasted on the surface of the floor panel has been conventionally used mainly for the purpose of improving the decorative feeling, and the following Patent Documents 1 to 3 exist as prior art related thereto. In the construction of a stone-laminated floor panel, first, the floor panel is first spread, and then the plywood is thrown away and pasted, and the plywood is spread while adhering and fixing the stone material in an overlying state. However, according to this, when carrying out maintenance of underfloor wiring and piping, a large amount of stone had to be broken and broken, which was troublesome and expensive.

  For this reason, in Patent Document 1, the adhesive is not fixed, and the adhesive elastic sheet is interposed between the stone material (floor stone material) and the floor panel (floor base material). The stones have large thickness variations, and there are steps on the surface between the stones (the cost becomes very high when the dimensional accuracy of the stones is increased), and the stones and the floor panel are only integrated by adhesive force. Therefore, cracks and chips are likely to occur in the stone due to the load.

On the other hand, when a concrete floor panel (base material) is hardened as in Patent Document 2, if a stone (floor finish) is placed on the top surface and integrally molded, a stone-laminated panel (floor panel) of a certain thickness is formed. ) And the problem of cracking or chipping of the stone is also improved. However, there is a problem in that a mold or a wooden mold for molding is required for each thickness of the stone, which increases the cost.

Therefore, if a stone is bonded and fixed to the upper surface of a general steel plate floor panel (for example, Patent Document 3), the above-described mold and wooden mold are not required, and the cost can be reduced. However, there is usually a low step portion having a quadrant-shaped cutout for mounting the panel presser at the corner tip of the floor panel, and the stone is not supported in this portion. Further, since the lower edge plate and the upper surface plate are combined over the entire periphery and the upper surface plate is wound around the lower surface plate (hemming process), the upper surface has a downward slope toward the outside. For this reason, a phenomenon in which the stone does not adhere to the floor panel occurs at the peripheral portion, and cracks and chips are likely to occur when a load is applied to the corner or side of the stone. Further, it is necessary to set a large amount of the adhesive so that an unbonded part does not occur, and there is a problem that the adhesive leaks out from every part of the side part, and the removal work becomes difficult.

Japanese Patent No. 3208679 Japanese Patent No. 2808219 Japanese Patent No. 4198279

The present invention solves such a problem, and even if a stone material is later bonded and integrated with a floor panel having a general structure, the stone material can be prevented from cracking or chipping, and the adhesive may leak. The purpose is to provide a few stone-pasted panels.

Under the above problems, the present invention provides a stone-laminated floor panel for a double floor in which stone is mounted on the upper surface of a floor panel that is floated on a foundation floor by a support leg. A thin plate-like spacer member having an L-shaped cross section composed of a mounting portion for placing a stone in a predetermined range from the outer peripheral end to the inside and a protruding piece portion protruding upward from the mounting portion is bonded to the outer periphery. The stone was placed on the part, and the floor panel and the stone were adhered to each other with the adhesive layer between the floor panel and the stone, and the projecting piece was placed on the side of the stone to regulate the position. A stone-coated floor panel for a double floor is provided.

Further, according to the present invention, in the above stone-pasted floor panel, the means described in claim 2, wherein the outer surface of the projecting piece and the outer peripheral surface of the floor panel are set flush with each other, the spacer described in claim 3 The means which makes the gap part by interrupting the middle of a member, The means which the spacer member described in Claim 4 is carrying out the linear form along the periphery of a floor panel, The spacer member described in Claim 5 is a protrusion piece The means which makes the gap part by missing a part, The means by which the raising member interposed between support legs is attached to the back surface of each corner part of the floor panel described in Claim 6 is provided.

According to the first aspect of the present invention, the spacer member composed of the placing portion and the projecting piece portion is provided on the substantially entire circumference of the floor panel, and the stone material is supported by the placing portion. Can support,
Reinforce the strength of the stone. Moreover, since the adhesive is filled between the floor panel and the stone, strong adhesiveness can be maintained. Furthermore, since the position of the stone is regulated by the projecting piece, the stone can be firmly placed at a predetermined position even during the adhesive curing.

According to the means of claims 2 and 4, it is easy to manufacture and attach the spacer member. According to the means of claims 2 and 4, it is easy to manufacture and attach the spacer member. According to the means, leakage of the adhesive from the spacer member can be concentrated at a predetermined location, and cleaning or the like is convenient. According to the means of Claim 7, even if it is a stone material with uneven thickness, the thickness of a stone affixed floor panel can be equalized.

As shown in FIGS. 1 and 5, the stone-laminated floor panel 1 of the present invention is supported by bonding and fixing on the base floor F at regular intervals (generally at intervals of 500 mm) in the same manner as an ordinary double floor. It is supported (floating) by the leg 2. Specifically, each stone-pasted floor panel 1 is put together and spread, and the corner portion of each panel 1 is supported by one support leg 2. Although details will be described later, a joint is formed by providing an interval of about 4 to 5 mm between the stone-laminated floor panels 1 and 1, and a joint material 7 such as a caulking material or cement is filled and finished.

The support leg 2 has a nut 23 screwed onto a support bolt 21 erected in the center of a metal ground plate 21 that is bonded and fixed to the foundation floor F, and a metal support plate portion and a lower part thereof. This is a structure in which a support cap 24 composed of a provided cylindrical portion is placed and a resin positioning pad 25 is put on the upper surface of the support plate portion. Therefore, if the nut 23 is rotated, the support cap 24 and the positioning pad 25 move up and down, and the height of the floor surface can be adjusted. A push screw 27 that can be pressed against the support bolt 22 is screwed onto the cylindrical portion of the nut 23 and the support cap 24, and is screwed in and fixed after the height adjustment. In addition to the cylindrical positioning pins 26, positioning blocks 28 are projected in a cross-sectional shape in plan view at four positions on the upper surface of the positioning pad 25 on which the corner portion of the stone pasting panel 1 is placed. Regulate position.

As shown in FIG. 2, the stone-laminated floor panel 1 of the present invention has a stone material 5 bonded and fixed to the outer periphery of the upper surface of a floor panel 3 having a general specification with four spacer members 4 interposed therebetween, and each corner. It is the structure which attached the raising member 6 for adjusting thickness to the back surface side of a part. The stone material 5 in this case is a granite or natural or artificial marble processed into a plate shape.

The floor panel 3 used in the stone-laminated floor panel 1 of this example has a sandwich structure in which a core material 33 made of particle board or the like is sandwiched and bonded between a steel plate upper surface plate 31 and a lower surface plate 32 ( As shown in FIG. 6, a commonly used double flooring for offices in which tile carpets are attached and finished as a surface finish can be applied as it is. For this reason, the exclusive metal mold | die etc. for shape | molding the stone pasting floor panel 1 become unnecessary, and can suppress product cost low.

The lower surface plate 32 has a structure in which it is drawn into a concave shape by press molding, and the upper end on the outer peripheral side of the concave portion is formed as a horizontal flange over the entire circumference. The upper surface plate 31 is substantially flat, the outer peripheral portion is overlapped with the flange of the lower surface plate 32, the lower surface plate 32 is wrapped downward so as to wrap around the end of the lower surface plate 32, and the both are integrated. Since the floor panel 3 is designed as a general office double floor, a panel presser (not shown) for fixing the floor panel 3 by being screwed into a support leg can be attached to the end of the corner. It has a shape. Specifically, a quadrant notch 34 for inserting the panel presser and the outer periphery thereof as a lower step 35 lower than the upper surface accommodates the panel presser and stands up to the upper surface. In addition, in the outer peripheral portion of one side, two wiring openings 36 for passing the wiring under the floor are usually recessed inward at two locations.

The spacer member 4 is a unit obtained by cutting a steel plate having a thickness of about 1 mm into a L shape in plan view with a constant width, and the horizontal mounting portion 41 and the outer end of the mounting portion 41 are bent upward by about 5 mm. The projecting piece portion 42 is L-shaped in sectional view. In this case, the L-shaped sides have the same length (isosceles L-shaped). As shown in FIG. 3, the spacer member 4 immediately exerts an adhesive force on the upper surface of the floor panel 3 before the mounting portion 41 is attached to the stone 5, for example, a hot melt adhesive, an adhesive tape, or a screw stopper. It is attached by fixing means such as. In this example, the outer surface of the projecting piece portion 42 is made to coincide with the outer peripheral surface of the floor panel 3 to ensure the convenience of the mounting operation and the accuracy of the mounting position.

As can be seen in FIG. 3, the floor panel 3 to which the spacer member 4 is attached in this way is flattened on the entire outer periphery of the floor panel 3 by the placement portion 41. That is, the structure has no step by covering the notch 34 and the low step portion 35 at the corner tip and the upper part of the through-holes 36 and 36. Since the stone 5 is placed on the placement portion 41 of the spacer member 4, the outer periphery of the stone 5 that is easily broken can be firmly supported, and the strength can be significantly increased. Moreover, although the clearance for this board thickness will be ensured between the floor panel 3 and the stone material 5 by the mounting part 41, since this clearance will be filled with an adhesive agent, this clearance gap is ensured. Forms an adhesive 12 having a sufficient number of layers, so that a homogeneous and strong adhesive force can be obtained.

  Furthermore, since the stone 5 is fitted in the state where the side surface is positioned on the inner side of the projecting piece portion 42, it is possible to prevent misalignment during the alignment period of the floor panel 3 and the curing period of the adhesive, and to improve the handleability. Have In the case of this example, since the pitch between the support legs 2 and 2 is set to 500 mm and the outer diameter of the floor panel 3 is set to 499 mm, if the plate thickness of the spacer member 4 is set to 1 mm, the projecting pieces 42 and 42 are formed. The inner surface dimension between them is 497 mm. On the other hand, the outer diameter dimension of the stone material 5 is set to 496 mm, and a gap of about 0.5 mm is formed on one side between the projecting piece portion 42 and the stone material 5 so as to absorb the outer diameter dimension error of the stone material 5. I have to.

In order to bond the stone 5 to the floor panel 3, an adhesive is applied to the upper surface of the floor panel 3 in the frame of the spacer member 4, and then the stone 5 is placed and pressed. Or after applying to the upper surface (actually the bottom surface) of the surface of the stone 5 placed upside down, the floor panel 3 is placed upside down and pressed. At this time, since the adhesive is spread over the entire upper surface of the floor panel 3 and the mounting portion 41, the stone material 5 is bonded on the entire surface, and an unsatisfactory adhesive force is obtained. As the adhesive, urethane or epoxy adhesives that can bond steel and stone are suitable.

By the way, when the stone 5 is pressurized, the adhesive tends to leak from the outer periphery of the spacer member 4, but the protruding piece 42 of the spacer member 4 can serve as a weir to prevent leakage. And since the clearance gap part 11 which does not provide the spacer member 4 is actively formed in the center of the edge | side where the spacer members 4 and 4 face each other, air and an adhesive agent escape intensively from this part. Therefore, it is only necessary to confirm whether or not the adhesive has leaked out, and only the gap portion 11 needs to be confirmed. Incidentally, the stone 5 can be variously selected in addition to the above-mentioned materials, and there is no particular limitation on the thickness. However, according to the structure of the present invention, even a thin one of about 15 to 20 mm does not crack at a predetermined load. Thus, the stone-pasted panel 1 can be reduced in weight.

As shown in FIG. 4, the raising member 6 is made of a hard synthetic resin block body such as ABS or PP, and is fixed to the rear surface of the corner portion of the floor panel 3. A cylindrical fixing protrusion 61 is formed on the upper surface of the raising member 6 (see FIG. 2), and is press-fitted into the mounting hole 37 formed on the rear surface of the corner portion of the floor panel 3, and is formed at a diagonal corner. A fixing screw 63 is screwed into the floor panel 3 from the fixing hole 62 and attached. A positioning hole 64 is formed at the concentric position on the back surface side of the fixed projection 61 to insert and position the positioning pin 26 (see FIG. 1) protruding from the support leg 2 in a press-fitted state.

As shown in FIG. 6, the stone-laminated floor panel 1 of the present invention is positioned by pressing the positioning hole 64 of the raising member 6 into the positioning pin 26 of the support leg 2 and bringing the positioning block 28 into contact with the side surface of the corner portion. In this state, it is placed and laid on the support cap 24, but due to the variation in the thickness of the stone material 5, the height from the bottom surface of each raising member 6 to the top surface of the stone material 5 also varies. When laid, steps are generated in each stone 5. Therefore, in the present invention, the stone-laminated panel 1 on which the raising member 6 has been attached is placed upside down and cut so that the bottom surfaces of the raising members 6 are aligned at the same height (horizontal) to complete the product. By doing so, the level of the upper surface of each stone-pasted floor panel 1 is aligned only by placing it on the support leg 2, and the finish has no step.

As shown in FIG. 7, a gap (joint) of about 4 mm is formed in the stone material 5 of the stone-laden floor panel 1 laid out in this way. This joint is filled with a joint material 7 such as a caulking material or cement, and is finished so as to maintain a certain water-stopping effect. In this case, it is suitable to previously press the foam rubber or resin backup material 8 formed in a string shape into the joint, but in the case of this example, the protruding piece of the spacer member 4 attached to the adjacent stone-laminated panel 1 The portions 42 and 42 protrude into the joint in a facing state (the distance between them is about 1 mm) so that the backup material 8 is supported and cannot be pushed any further. Therefore, the backup material 8 can be installed at a certain height, and the finish of the joint material 7 can be made easy and beautiful.

  When the backup material 8 is installed along the vertical and horizontal joints, as shown in FIGS. 8 and 9, the floor panel 3 crosses up and down at the corner abutting portion (intersection of the joints). Therefore, the spacer member 4 of this example provides an appropriate gap between the projecting piece portions 42, 42 at the corner portion, and further chamfers the upper end portion to form a relief 43, thereby lowering the intersecting backup material 8 downward. It escapes to prevent upward swelling. Thereby, the height of the joint material 7 which cross | intersects mutually becomes substantially equal, The space required in order to pack the joint material 7 can be ensured upwards, and the situation where the joint material 7 becomes too thin can be prevented. .

FIG. 10 is a perspective view showing another embodiment of the spacer member 4 constituting the stone pasting panel 1 of the present invention. The difference from the previous embodiment is that the entire L-shaped portion in plan view sandwiches the corner. The gap portion 11 is provided at a position offset from the center of the side of the floor panel 3 toward the corner portion (unequal side L-shape). Further, the gap portion 11 is formed by forming only the placement portion 41 at the end on the short side (or long side), that is, by providing a missing portion that does not form the protruding piece portion 42. By doing so, a greater range of the stone material 5 can be supported by the spacer member 4, so that the strength is complemented. In this case, it is preferable to set the spacer member 4 so as to block the through-holes 36, 36. In other words, the length of the unequal side may be set as appropriate according to the position of the through-hole 36.

FIG. 11 is also a perspective view showing another embodiment of the spacer member 4 constituting the stone-pasted panel 1 of the present invention, but this example is a linear spacer member 4 along each peripheral edge of the floor panel 3. , I try to match at the corner. The gap portion 11 is not actively formed in order to support the corner tip of the stone 5 with the placement portion 41 (close the notch 34 and the low step portion 35 of the floor panel 3). Both sides (the corner portions to be abutted are provided with a missing portion that does not form the projecting piece portion 42 to allow the adhesive to leak out in the same manner as the gap portion 11. The above-mentioned L-shaped spacer member 4 in plan view has no seam at the corner tip position of the floor panel 3, so that the reinforcement effect of the stone 5 is enhanced. If the linear spacer member 4 is used as in this example, it can be made excellent in handling properties such as storage and transportation.

FIG. 12 is also a perspective view showing another embodiment of the spacer member 4 constituting the stone-pasted panel 1 of the present invention, but this example is also a linear spacer member 4 along each peripheral edge of the floor panel 3. Although it is made to collide with a corner part, it attaches to the one side in order so that the edge of the one side of the mounting part 41 may correspond with the outer peripheral surface of the floor panel 3. Accordingly, the gap portion 11 is formed by providing an L-shaped missing portion that does not form the protruding piece portion 42 only at the end portion (to be referred to as a corner portion to be abutted) toward one side. However, when the mounting portion 41 has a large width, it is not necessarily provided in the L shape, and may be provided only at the end. In this case, it is preferable in terms of cost and workability that the four linear members or the unequal L-shaped spacer members 4 in this example have the same shape.
