Description

  According to the present invention, a floor panel in which a surface finishing material such as a tile carpet is pasted on its upper surface in a one-to-one relationship, a so-called one-to-one floor panel is fixed to a support leg standing on a basic floor surface by a panel presser. This relates to a panel fixing structure.

  Conventionally, when the floor panel is fixed to a support leg standing on the foundation floor surface for the purpose of improving earthquake resistance and preventing the floor panel from rattling, the corners of the four floor panels supported by the support leg In the assembly portion, the panel presser found in Patent Document 1 is generally fixed by screwing it into a support leg from above. By the way, surface finishing materials such as tile carpets are usually attached to the upper surface of the floor panel. The surface finishing material has the same external dimensions as the floor panel after the floor panel is fixed with a panel presser. Sticking with adhesive material while shifting from the joint of the floor panel and one-to-one sticking with the surface finish of the same external dimensions aligned and fixed in advance when manufacturing the floor panel There is a type (in some cases, the surface finishing material may be bonded and fixed after fixing the floor panel at the construction site).

  Randomly-attached types have a beautiful finish with no noticeable steps or gaps between the floor panels, but when attaching / detaching one floor panel, it is usually necessary to peel off and paste the four surface finish materials. Maintenance is low. On the other hand, the one-to-one attachment type does not need to remove the surface finish when attaching and detaching the floor panel, and is excellent in maintainability, but the steps and gaps between the floor panels are easily noticeable. Therefore, both of them can be used properly depending on whether or not importance is placed on maintainability, but the problem of steps and gaps between floor panels is being solved by improving member accuracy and construction accuracy, and it is excellent in maintainability one-to-one. The paste type is attracting attention.

  However, when fixing such a one-on-one type floor panel, the corner tip of the surface finish must be lifted in order to operate the panel presser, and this reduces the maintenance performance. There is. In addition, there is a problem that when the surface finish material is rolled up, the wrinkles remain and the aesthetic appearance is lost, and there is a danger that it is struck by the passage of people and trolleys. Therefore, in such a one-to-one bonding type floor panel, there are many cases in which the floor panel is not fixed to the support leg erected on the foundation floor surface.

  Therefore, in Patent Document 2, in order to prevent such a situation, a flat plate-like panel pressing member 4 corresponding to the thickness of the surface finishing material 2 is provided in the opening 5 that is notched in the surface finishing material (carpet) 2. The panel fixing screw 7 is screwed into the panel fixing screw hole 6 of the support leg 3 and fastened, whereby the corner portion of the floor panel is connected and fixed to the support leg 3 and integrated with the upper end of the peripheral edge of the panel pressing member 4. The edge 5 of the opening portion of the surface finishing material 2 is pressed down by the carpet presser flange 4C projecting on the surface. However, when the surface finishing material 2 is not a soft material such as carpet but a hard material such as a resin tile, the panel pressing member 4 protrudes upward from the surface finishing material 2 and causes a step. Could not respond.

As a method to solve all of the above problems, it is considered to cut off the corner tip of the surface finish material according to the shape of the head of the panel presser and expose the panel presser to be flush with the surface finish. It is done. However, since there are five types of surface finishes with a thickness of about 2 to 7 mm even for general ones, there are special products with different thickness settings for the panel presser heads according to various surface finishes. Necessary, costly and impractical.
JP 2001-049856 A Japanese Utility Model Publication No. 04-1111843

  In the present invention, when fixing a floor panel in which the surface finishing material is a one-to-one bonding type to the support leg, the panel presser is mounted on the same surface as the surface finishing material by using a raising member having a specific structure. This eliminates the need to roll up each surface finishing material, and eliminates the need to use a dedicated panel presser that matches the thickness of the head for each thickness of the surface finishing material.

  Under the above-mentioned problems, the present invention provides a quarter circle of both the notch portion in which the tip of the corner is cut out and the lower step portion having a predetermined depth lowered from the upper surface around the notch portion. A screw cylinder that can be inserted into a notch and can be inserted into a notch and screwed into a support leg that exists below the floor panel that has a surface finish applied to the upper surface in a one-to-one relationship with the upper surface. And a floor panel fixing structure that is fixed by a panel presser having a head that presses the lower step portion, a cutout portion is provided by cutting away a portion corresponding to the lower step portion of the floor panel at the corner of the surface finishing material. In addition, when a raised member having a predetermined thickness is interposed between the lower step portion and the head of the panel presser and the panel presser is screwed into the support leg, the head of the panel presser is regulated by the raised member and the upper surface of the head And the top surface of the finishing material stop at approximately the same height Providing a fixed structure of the floor panel, wherein the door.

  Further, the present invention provides the above fixing structure, wherein the raising member has the same thickness as the surface finishing material, and the head of the panel presser has the same thickness as the depth of the low step portion, The raising member described in claim 3 is configured to have a ring shape in which a hole into which a screw body portion of the panel presser can be inserted is formed or a semi-ring shape in which a part of the circumference is missing, the screw according to claim 4. The configuration in which the screw barrel and the raising member are integrated when the barrel is inserted into the hole of the raising member, and the configuration in which the integration of the screw barrel and the raising member is tight fitting or engagement is provided. To do.

  According to the means of claim 1, the panel retainer having a high manufacturing cost is of one specification and is used in common regardless of the thickness of the surface finishing material, and a raised member having a lower manufacturing cost than the panel retainer is used for the surface finishing. Costs can be reduced because it only needs to be prepared according to the thickness of the material. Further, when using the panel retainer, it is possible to save the trouble of rolling up the surface finishing material one by one, and since the corner of the surface finishing material that enables this can be cut out mechanically, the cost is not greatly increased. Furthermore, the surface finishing material and the head of the panel presser are flush with each other, and no depression or the like is formed.

  According to the means of claim 2, since the head of the panel presser is formed with the same thickness as the depth of the lower step portion of the floor panel, it can be used as a normal panel presser that is flush with the upper surface of the floor panel. Is suppressed. According to the third aspect of the present invention, even if the ring shape or the half ring shape is used, the raising member has a simple structure and can be manufactured at a low cost. According to the means of claim 4, it is possible to save the trouble of removing the raising member by another operation when the panel presser is removed, not to lose, and to save the trouble of positioning the raising member when attaching the panel presser again, Workability is improved. According to the means of claim 5, the above-described effect becomes more reliable and easy to operate.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing the relationship between the support leg of the present invention and the floor panel, FIG. 2 is a plan view showing the laying state of the floor panel using the support leg of the present invention, and FIG. Although it is OA sectional drawing, the support structure of the floor panel in this invention was supported by the support leg 6 placed on the base floor surface 2 in the position of the corner of the square floor panel 1, and the support leg 6. It consists of a panel presser 3 for fixing the floor panel 1 to the support leg 6.

  Among these, the support legs 6 are formed by extending screw struts 61 having sufficient rigidity against falling from a ground plate 60 that is appropriately fixed and placed on the foundation floor 2. The receiving plate 63 is received by the screwed nut 62 (the nut 62 is fixed by caulking to the receiving plate 63), and the mounting plate 64 on which the floor panel 1 is placed is supported by the receiving plate 63. In this case, the mounting board 64 is made of a molded product of resin such as polyethylene, and its outer peripheral end is bent downward to wrap around the outer periphery of the receiving board 63 and enters the receiving board 63 at the center. A cylinder body 72 is formed.

  The floor panel 1 is made of a steel plate having a structure in which a flat top plate 13 is placed on a bottom plate 12 having a frame shape with an opening at the top, and the outer periphery is wound around and joined. It has an overlapping flange with the face plate 12 (not shown). A quarter-circular cutout 15 is formed in the overlapping flange at the corner tip, and a lower step 14 is formed around the cutout 15 in the same circular shape and stepped from the upper surface to a predetermined depth. In the diagonal direction, the corner side surface 18 that is the vertical wall of the lower surface plate 12 descends at a predetermined distance from the standing portion 16 that stands on the outer periphery of the low step portion 14. is there. Therefore, an inverted U-shaped pocket is formed between the upright portion 16 and the corner side surface portion 18, and this is referred to as a neck portion 17. In addition, a side surface portion 19 extends in the side direction from both ends of the corner side surface portion 18 as a positioning side surface portion.

  A thick edge portion 20 is formed extending from the upper surface of both ends in the circumferential direction of the standing portion 16 to the vicinity of the side surface portion 19 so as to be thicker downward along the edge in the side direction. The thick edge portion 20 is obtained by the winding of the horizontal flange of the lower surface plate 12 around the outer periphery of the upper surface plate 13, and has a thickness protruding downward from the overlapping flange by the thickness of the upper surface plate 13 wound to the lower surface side. It is meaty. In addition, the upper surface continuing from the upper end of the upright portion 16 is formed on the flat upper surface 10, and the lower end of the corner side surface portion 18 and the side surface portion 19 is formed on the flat bottom surface 11.

  The panel retainer 3 includes a disc-shaped head 30 and a screw body 31 having a diameter smaller than that of the head 30. The head 30 has a diameter that allows the corners of the four floor panels 1 to enter into the low step portion 14 that is circular in the assembled state without gaps, and the same height (level) as the upper surface 10 of the floor panel 1. Has a thickness of The screw body 31 has a diameter that enters the notch 15 that is also circular, and enters a through hole provided in the center of the cylinder body 72 formed in the center of the mounting board 64. In the center, a screw (female screw) that can be screwed onto the screw support 61 and opens at the lower end is formed.

  The above floor panel 1 is placed on the platform 64 of the support leg 6. In this case, the platform 64 is formed with a horizontal receiving surface portion 65 existing below the low step portion 14 on the innermost periphery. As described above, the cylindrical body 72 is formed from the inner peripheral end of the receiving surface 65, and the through-hole into which the screw body 31 is inserted is formed at the center of the cylindrical body 72. In the diagonal direction following the outer peripheral side of the receiving surface portion 65, the high weir portion 66 stands up annularly with a predetermined thickness from the receiving surface portion 65 at a position of four equal parts, and between the circumferential directions of the high weir portion 66 Low dam portions 69 that are shorter than the high dam portions 66 are also formed in the same thickness at four locations. Further, a partition portion 70 having a lower height than the low weir portion 69 rises in a side band shape on the outer periphery of the low weir portion 69, and vertical ribs are formed on both side surfaces of the outer end portion. An abutting portion 71 protruding in a shape is formed, and a flat mounting portion 68 is formed on the outer side from the roots of the high dam portion 66, the low dam portion 69 and the partition portion 70.

  In this case, the height of the receiving surface portion 65 from the placing portion 68 is set to be lower than the height from the bottom surface 11 of the floor panel 1 to the lower surface of the low step portion 14, and the height of the high weir portion 66 is similarly set to the neck portion 17. The height of the low weir portion 69 is also set lower than the height to the lower surface of the thick edge portion 20. Further, since a gap of about 1 mm is provided between the edges of the laid floor panel 1 so as not to generate a rubbing sound, the width of the abutting portion 71 portion of the partition 70 is equal to this gap. The length from the side edge to the side side surface part 19 is added.

  In the above, the thickness of the high dam portion 66 and the low dam portion 69 is set narrower than the width of the neck portion 17. In this case, the diameters of both centers are set to be substantially the same. When the floor panel 1 is placed on the platform 64, the inner periphery and the outer periphery of the high weir portion 66 are the inner periphery of the neck portion 17 (the standing portion 16). ) And the outer periphery (corner side surface portion 18). Depending on the strength type, the thickness of the steel plate of the floor panel 1 may be changed. Due to this difference, even if the width of the neck portion 17 is wide, the high weir portion 66 is inserted into the neck portion 17 without any trouble. is there.

  In addition, in this example, even if the steel plate thickness of the floor panel 1 differs depending on the strength type, the high dam portion 66 is arranged so that the high dam portion 66 is accommodated in the neck portion 17 of the floor panel 1 without causing a positional shift or the like. A position restricting piece 67 is provided on the inner periphery of the head. The position restricting piece 67 in this example has a deformable vertical rib shape formed integrally with the high dam portion 66, and usually the tip of the position restricting piece 67 lightly touches the outer periphery of the standing portion 16 constituting the inner peripheral wall of the neck portion 17. It is like that. Therefore, if the floor panel 1 is of a type with a thin steel plate, the neck portion 17 is wide, so that it is lightly deformed. If the floor panel 1 is of a thick type, the neck portion 17 is narrow, so that it deforms considerably. However, in any case, the position restricting piece 67 is inserted into the neck portion 16 in a state of being in contact with no gap, and does not cause the positional deviation of the floor panel 1 after laying.

  Next, a method of bonding the support leg 6 to the base floor surface 2 and a method of placing the floor panel 1 on the support leg 6, an adhesive is applied to the ground plate 60 of the support leg 6, and If the nut 62 is moved up and down and the platform 64 is adjusted to a predetermined height after being placed in accordance with the corner position of the floor panel 1, the side surface portions 19 on both sides sandwiching the lower step portion 14 of the floor panel 1 are high. It pushes into the low step part 14 side until it abuts against the abutment parts 71 on both sides sandwiching the weir part 66 or the abutment parts 71 on both sides sandwiching the high weir part 66 of the support leg 6 are the low stage of the floor panel 1. The support leg 6 is pushed into the floor panel 1 side until it abuts on the side surface parts 19 on both sides sandwiching the part 14, and the bottom surface 11 is placed on the mounting part 68, and the support leg 6 is aligned with the normal position with respect to the floor panel 1. Fix to the foundation floor 2 (at this time the adhesive is not solidified).

  As a result, the movement of the floor panel 1 toward the lower step portion 14 is restricted by the abutting portion 71, and the neck portion 17 is always fitted into the high weir portion 66 in a regular positional relationship, and at the same time, the vertical rib 67 is raised. 16 is deformed in contact with the strength as described above. This state is a state in which the floor panel 1 is set at a regular position. When the floor panel 1 is laid down while repeating such an operation, each floor panel 1 holds an appropriate interval (set interval). Laid.

  Next, when the panel retainer 3 is fitted into the lower step portion 14 and screwed into the screw support 61, the outer periphery of the screw barrel portion 31 is lowered while being guided by the inner periphery of the cylinder barrel portion 72 of the platform 64. The head 30 is inserted into the low step portion 14 and presses the low step portion 14 on its back surface. Even in this case, in many cases, the back surface of the low step portion 14 is not in contact with the receiving surface portion 65 of the platform 64, and the low step portion 14 is pressed downward in a state of being elastically deformed. Is in a fixed state.

  At this time, the panel retainer 3 has an effect of easily and reliably deforming the vertical rib 67 by the tightening force, and reliably preventing the floor panel 1 from being lifted by the original restoring force of the vertical rib 67. Therefore, even if the rigidity of the vertical rib 67 is high, it can be easily deformed, and the position regulating force of the floor panel 1 can be set higher.

  On the other hand, for the floor panel 1, the surface finishing material 4 is attached to the upper surface 10. The surface finishing material 10 in the present invention is pasted in a one-to-one relationship with the floor panel 1, but the size is the same as the floor panel 1, but the corners are the same as the low step portion 14. The cut portion 40 is cut by a quarter circle of the same size. The cutting portion 40 is processed by press molding and can be accurately performed, and the cost is not so high.

  This is affixed to the floor panel 1 with an adhesive, but in the case of one-to-one adhesion, it is usually affixed at the stage of shipment from the factory. The surface finishing material 4 in this case has a thickness of 2 to 7 mm, and there are a resin tile type and a carpet type in terms of material.

  Next, the present invention will be described. The surface finishing material 4 provided with a cut portion 40 is stuck on the upper surface 10 of the floor panel 1. It will dive under the finishing material 4. This becomes a depression and is dangerous when walking. Therefore, the raising member 5 is placed on the lower step portion 14 of the floor panel 1, and the panel presser 3 is screwed from above. In this screwing, the screw body 31 is screwed into the screw strut 61 of the support leg 6. However, when the screw body 31 is screwed to a certain position, the head 30 of the panel presser 3 hits the raising member 5 and cannot be screwed further. .

  At the same time, the head 30 sufficiently presses the raised member 5 and the lower step portion 14, but at this time, the raised member 5 so that the upper surface of the head 30 and the upper surface of the surface finish 4 are substantially the same. The thickness is set. Therefore, the thickness of the raising member 5 corresponds to the thickness of the surface finishing material 4 being used. Further, if the colors are of the same color system, the panel presser 3 does not stand out so much.

  The raising member 5 that meets this requirement has a ring shape with a hole 50 through which the screw body 31 of the panel retainer 3 can be inserted. In the present invention, once the raising member 5 is used, the panel retainer 3 is used. It is made to integrate with. Specifically, about three vertical rib-shaped deformation portions 51 are formed on the inner periphery of the raising member 5. And the dimension (inner diameter dimension) which goes around the top part of the deformation | transformation part 51 is made about 0.5 mm smaller than the outer diameter dimension of the screw trunk | drum 31, and the screw trunk | drum 31 is once put in the hole 50 of the raising member 5. When inserted, they are integrated so that they are not normally separated. In this respect, the material of the raising member 5 is suitably a resin that can be elastically deformed. However, when the panel retainer 3 is made of a resin, a metal may be used.

  The panel presser 3 and the raising member 5 that have been used once do not need to be separated from each other. Therefore, even if the panel retainer 3 is once removed for maintenance or the like, the two do not fall apart and dissipate. However, it can be used again as the standard panel presser 3 because it can be separated by forcibly removing it. The panel retainer 3 and the raising member 5 may be integrated in advance by using the panel retainer 3 screwed into the support leg 6 after being integrated so as not to come off before use. Alternatively, a method may be used in which the raising member 5 is placed on 14 and the panel presser 3 is passed through the raising member 5 and automatically integrated by screwing operation.

  FIG. 4 is a perspective view showing another example of the panel presser 3 and the raising member 5, but the present example is the same in that the raising member 5 has a ring shape, but the screw body 31 of the panel presser 3. A screw is also formed on the outer periphery, and an engagement portion 52 that engages with the screw is formed on the inner periphery of the raising member 5. The engaging portion 52 is a fin-like protrusion that is divided from the hole 50 in the circumferential direction into three divisions, and once the screw passes through the protrusion, the protrusion bites into the screw thread and the two are integrated.

  In this case, a screw (male screw) is formed on the outer periphery of the screw body 31, but if the above-described screw (female screw) is formed at the center, the screw support 61 may be of the above-described standard structure. . However, if a female screw is formed on the upper portion of the screw support 61 of the support leg 6 (not shown), only a male screw is formed on the outer periphery of the screw body 31. In this case, the screw body 31 can be replaced with a general-purpose bolt, and the head 30 may be a washer-like one (not shown) having a recess into which the head of the general-purpose bolt can be dropped at the center of the upper surface. There is an advantage that the presser 3 can be manufactured at low cost.

  FIG. 5 is a perspective view showing still another example. In this example, the raised member 5 is formed in a semi-ring shape having a cut portion 53 missing in a part in the circumferential direction. The screw body 31 of the panel retainer 3 is formed with a locking ridge 32 projecting in the circumferential direction at a position about the thickness of the raising member 5 below the head 30. The mounting method of the raising member 5 to the panel presser 3 may be performed by forcibly inserting the screw body portion 31 into the hole 50 of the raising member 5 as in the previous examples. However, according to the raising member 5 of this example, when the locking protrusion 32 is passed over, the cutting portion 53 of the raising member 5 is elastically deformed into a slightly open state to facilitate integration, and the diameter of the hole 50 is increased. Is set smaller by about 0.5 mm than the outer diameter of the screw body 31, the screw body 31 can be tightened and integrated more firmly.

  The size (gap) of the cutting portion 53 is arbitrary, but if it becomes too large, the portion that cannot press the low step portion 14 increases. On the other hand, when the distance is small, for example, the gap may be greatly opened when the locking ridge 32 is moved over in a state where the end faces are usually in contact with each other. Further, the position of the locking ridge 32 is set in a relationship in which the upper surface of the raising member 5 is pressed against the lower surface of the head 30, but may be set in a relationship having a gap. There is no problem as long as the member 5 can be prevented from falling off.

  FIG. 6 is a perspective view showing still another example, but this example is a modification of the above-described semi-ring shaped raising member 5, and a locking groove that is recessed in the circumferential direction in the screw body 31. 33, and a locking protrusion 54 that fits into the locking recess 33 is formed on the inner periphery of the hole 50 of the raising member 5 (positions of the locking recess 33 and the locking protrusion 54). Is set such that the upper surface of the raising member 5 is pressed against the lower surface of the head 30).
