Description

  The present invention relates to a floor panel support structure for supporting a floor panel on a foundation floor surface.

  Conventionally, the floor panel is placed on the support leg placing plate in a state where the floor panel is positioned so that a gap of about 1 mm is formed between adjacent floor panels so that the ends of the floor panels do not come into contact with each other to generate a rubbing sound. After that, the panel presser was fastened to the support leg to fix the floor panel.

  For example, in the support leg of Patent Document 1, a high weir portion in which a reverse U-shaped neck portion higher than a low step portion formed in a diagonal direction from a low step portion at the corner tip of the floor panel is provided on the support leg mounting plate. The floor panel is positioned by engaging the partition part provided on the mounting board between the side surface parts of the adjacent floor panels, and the lower step at the corner tip of the floor panel is placed on the receiving surface part of the mounting board and the panel. The presser head is clamped and fixed from above and below.

  In addition, in the support leg (post) of Patent Document 2, the positioning protrusion provided on the support leg is inserted into the positioning hole formed on the bottom surface of the floor panel, and positioning is performed. As with the high weir, a second positioning part to be inserted into the neck (rib fitting recess) formed at the corner of the floor panel (floor panel) is provided on the platform (receiving part cover), and the adjacent floor panel The floor panel is positioned by the first positioning part that abuts between the edge flanges and forms a certain gap between the edge flanges, and the floor is pressed by a panel presser (presser member) inserted with a fastener such as a flat head screw. The floor panel is fixed by tightening the fixing tool on the support leg while pressing the lower step (presser piece) of the panel corner from above.

  In common with such a positioning structure, in order to absorb the manufacturing error of the floor panel and the mounting board, it is necessary to allow a margin for the fitting between the two. It was difficult to completely prevent misalignment.

  Furthermore, in office buildings, etc., high-strength type floor panels may be laid in the passage sections where people frequently come and go, and general-strength type floor panels may be laid in office rooms that serve as office spaces. In order to use the panel presser in common for both types of floor panels, it is common to unify the dimensions of the lower step portion of the floor panel in accordance with the dimensions of the head of the panel presser.

  FIG. 9 is a plan view showing a conventional floor panel support structure, and FIG. 10 is a cross-sectional view taken along the line A′-O-A of FIG. 9. In the case of a steel floor panel, the left core material a is enclosed. There is a general strength type (A) and a high-strength type (B) with only the right side steel plate, and the general strength type (A) is the thickness of the steel plate that is the material of the high-strength type (B) floor panel. Since the width of the neck part d located on the outer peripheral side rear surface of the low step part c, which is unifiedly set in accordance with the dimensions of the head of the panel presser b, is widened, the width of the neck part d is increased. When the floor panel is placed by using the platform e of the supporting legs whose dimensions are set, in the wider floor panel, between the neck part d and the high weir part h, the side part i of the floor panel, the partition part f, A gap occurs between the floor panels, and when external force is applied, the floor panels come into contact with each other (displacement) and generate a rubbing sound. Put away.

  Note that the general strength type (A) includes a hollow structure that does not enclose the core material a. In this case, the thickness of the steel plate is increased to increase the strength, so the width of the neck portion d is narrow. It has become. Further, the high strength type (B) also has a solid structure in which a core material is encapsulated. In this case, the thickness of the neck portion d is wide since the plate thickness of the steel plate is reduced. For this reason, in the following, the expression of strength type is avoided and referred to as wide type and narrow type (collectively referred to as wide narrow type). The steel plate with the thinnest thickness is the general strength type (A) in which the core material a is enclosed. The steel plate with the largest thickness is the hollow structure high strength type (B), and the width of the neck d is the maximum. A difference of about 2 mm occurs.

  Furthermore, during the laying work or during the curing period, the support legs are displaced when the adhesive that fixes the support legs to the foundation floor is not dry, and the gaps between the floor panels are fixed in a distorted state. There is also a fear. Moreover, if it is a laying type | mold which does not adhere a support leg to a foundation floor surface, the position shift of a support leg generate | occur | produces also in a normal use condition, and there exists a possibility that the clearance gap between floor panels may go out of order.

  On the other hand, contrary to the above, there is a case where the width of the neck portion d is uniform even for floor panels having different wide and narrow types, but this time, on the contrary, the head outer peripheral surface of the panel presser b and the neck portion d. It is not preferable because a gap is generated between the upright portion g located on the inner peripheral side of the wall and the gap appears as irregularities on the floor surface. In order to overcome the above problems, it is only possible to use a dedicated platform e in which the size of the high weir portion h is set for each of the wide and narrow floor panel types, but this increases the cost. Even in that case, since the support legs for the thicker floor panel are used in common at the boundary between the passage part and the living room part, the positional deviation of the floor panel is It cannot be prevented.

Furthermore, as a problem unique to Patent Document 2, the positioning structure becomes diversified, such as the protrusions and the first and second positioning parts, and the structure becomes complicated. Since the first positioning part with a narrow width is in contact between the end parts, the first positioning part may be crushed or the edge part of the floor panel may ride up, which is a sufficient positioning effect. It is pointed out that is not demonstrated.
JP 2001-049856 A Japanese Patent Laid-Open No. 2003-232124

  In the present invention, even if a plurality of wide and narrow floor panels having different thicknesses of steel plates are used, it is possible to secure a proper gap between the floor panels by preventing misalignment with a common support leg platform. Is.

Under the above-described problems, the present invention provides a low step portion recessed from an upper surface at a corner tip, and a corner side surface portion descending at a predetermined interval from a standing portion rising from the outer periphery of the low step portion. A floor panel in which a square floor panel having an inverted U-shaped neck is formed and supported by a platform having a high weir part that is attached to a screw column that is erected on the foundation floor and inserted into the neck on the upper surface. In this support structure, the thickness of the high weir portion has a gap at the inner and outer circumferences of the neck, and the elastic body can be deformed by pressing the neck at the inner circumference of the high weir and projecting toward the inner circumference of the neck. Provided is a floor panel support structure characterized in that a deformed portion made of a rib is formed.

Furthermore, the present invention provides the above support structure, wherein the high dam part is provided at four positions at equal positions on the platform, and the vertical ribs are formed in about 2 to 4 in one high dam part. According to another aspect of the present invention, there is provided a means described in claim 3 in which the deformed portion is replaced with a longitudinal rib and the ends of the longitudinal rib are connected to form a hollow projection.

In the above support structure, the present invention positions the floor panel by abutting a pair of positioning side surfaces formed on both sides of the floor panel on the upper surface of the mounting board, as defined in claim 4. The means for forming the abutting portion, the positioning side surface portion according to claim 5, wherein the positioning side surface portion extends along the side direction of the floor panel, and the abutting portion is inserted between the side side surface portions of the adjacent floor panels. The means formed on the side surface of the partition portion, the positioning side surface portion according to claim 6 , wherein the positioning side surface portion is a hole side surface portion extending along a side direction to an inner periphery of the hole formed on the bottom surface of the floor panel, and the abutting portion is The means formed in the side surface of the pin-shaped projection part inserted in a hole, The means by which the panel presser screwed in a screw | thread support | pillar described in Claim 7 is fitted are provided.

According to the first aspect of the present invention, the high weir portion is inserted without interfering with the neck portion even if the width in the inner and outer directions of the neck portion is widened due to different types of wide and narrow or manufacturing errors (this is also unavoidable). The That is, the inner peripheral side (standing part) of the neck always interferes with the deformed part, and the deformed part is deformed to ensure insertion. In this case, the deforming portion may be integrally formed with the mounting board and the resin, or even when the mounting board is made of metal, the deforming portion may be attached separately. On the other hand, since a gap is secured between the outer periphery of the high weir portion and the outer peripheral side (corner side surface portion) of the neck portion, it is inserted without any problem regardless of the width of the neck portion. This means that it is only necessary to unify the dimensions of the lower step portion of any wide and narrow floor panels, and it is possible to use a common platform, which contributes to cost reduction. .

  Of course, there is a limit to the range in which the deformable part can be deformed, but in general, there are only two types of wide and narrow types, the general strength type and the high strength type, hollow and solid, respectively. The deformation range of the deformation portion is set so as to correspond to the dimensional difference in the width of the neck portion, and there is no problem. In other words, even if the width of the neck of the floor panel is wide due to different wide and narrow types or manufacturing errors, the inner peripheral side of the neck always abuts against the deformed part and deforms it, and between the inner peripheral side and the deformed part This does not cause a gap that causes a positional shift. However, when the width of the neck portion is wide, the deformation amount of the deformation portion is only small.

According to the means of claims 4 to 6 , the floor panel is pressed against the support leg side until the positioning side surface portion of the floor panel comes into contact with the abutting part, or conversely, the support leg is pressed against the floor panel side. The movement to the low step side and the rotational deviation in the horizontal plane are restricted, and it becomes easy and reliable to fit the neck portion and the high weir portion in a regular positional relationship. Due to the pressing force of the panel presser against the floor panel, the deformation of the deforming portion is promoted, and the setting of the floor panel becomes easy and reliable.

  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 a floor panel is the floor panel 1 supported by the support leg 3 placed on the foundation floor surface 2 in the position of the corner of the floor panel 1 which made the rectangle, and the support leg 3. And a panel presser 4 for fixing the frame to the support leg 3.

  Among these, the support leg 3 is formed by extending a screw column 6 having sufficient rigidity against falling from a grounding plate 5 that is appropriately fixed and placed on the foundation floor 2. The receiving plate 8 is received by a screwed nut 7 (the nut 7 is fixed by caulking to the receiving plate 8), and the receiving plate 8 further supports a mounting plate 9 on which the floor panel 1 is placed. In this case, the mounting board 9 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 8 and enters the receiving board 8 at the center. A cylindrical body portion 23 is formed.

  The floor panel 1 (generally referring to the general strength type 1 (A) in which the core material on the left side in the figure is enclosed and the high strength type 1 (B) including only the right side steel plate) is generally referred to as an edged container. It is made of a steel plate having a structure in which a flat upper surface plate 25 is put on a lower surface plate 24 and the outer periphery is wound around and joined, and the entire periphery has a superposed flange of the upper surface plate 25 and the lower surface plate 24 (illustrated). (Omitted). A low step portion 10 having a four-radius circular cutout portion 26 is formed in a four-radius circle shape on the overlapping flange at the corner tip, and is formed in a diagonal direction from an upright portion 27 on the outer periphery of the low step portion 10. The corner side surface portion 11a, which is the vertical wall of the lower surface plate 24, descends at a predetermined interval. Therefore, an inverted U-shaped pocket is formed between the standing portion 27 and the corner side surface portion 11 a, and this is used as the neck portion 12. From both ends of the corner side surface portion 11a, side side surface portions 11b extend in the side direction as positioning side surface portions.

  In the side direction from the upper surface of both ends of the upright portion 27, a thick edge portion 13 that is thicker downward along the edge 28 is formed to extend to the vicinity of the side surface portion 11b. The thick edge portion 13 is obtained by winding the horizontal flange of the lower surface plate 24 around the outer periphery of the upper surface plate 25, and has a thickness protruding downward from the overlapping flange by the thickness of the upper surface plate 25 wound to the lower surface side. It is meaty. In addition, the upper surface continuing from the upper end of the upright portion 27 is formed on the flat upper surface 14, and the lower end of the corner side surface portion 11 a and the side surface 11 b is formed on the flat bottom surface 15.

  The panel retainer 4 includes a disk-shaped head 16 and a body 17 having a smaller diameter than the head 16. The head 16 has a diameter that allows the corners of the four floor panels 1 to enter the lower step part 10 that is circular in the assembled state without gaps, and a thickness that is flush with the upper surface 14 of the floor panel 1. ing. The trunk portion 17 has a diameter that enters the circular cutout portion 26, and its outer periphery is in sliding contact with the inner circumference of the through hole 29 at the center of the cylinder barrel portion 23 formed at the center of the platform 9. In the center, a screw portion that can be screwed onto the screw support 6 is formed.

  The above floor panel 1 is placed on the platform 9 of the support leg 3. In this case, the platform 9 is formed with a horizontal receiving surface portion 18 existing below the low step portion 10 on the innermost periphery. A cylindrical body portion 23 is formed from the inner peripheral end of the receiving surface portion 18, and a through hole 29 into which the body portion 17 enters is formed at the center of the cylindrical body portion 23. In the diagonal direction following the outer peripheral side of the receiving surface portion 18, a high weir portion 19 stands in a ring shape with a predetermined thickness from the receiving surface portion 18 at a position that is equally divided into four portions. Low dam portions 21 that are shorter than the dam portions 19 are also formed in the same thickness at four locations. Further, a partition portion 22 having a lower height than the low dam portion 21 is raised in a belt shape on the outer periphery of the low dam portion 21, and is raised in the form of vertical ribs on both side surfaces of the outer end portion. The abutting portion 22a is formed, and a flat mounting portion 20 is formed on the outer side from the base of the high dam portion 19, the low dam portion 21 and the partition portion 22.

  In this case, the height of the receiving surface portion 18 from the mounting portion 20 is set to be lower than the height from the bottom surface 15 of the floor panel 1 to the lower surface of the low step portion 10, and the height of the high weir portion 19 is similarly set to the neck portion 12. The height of the low dam portion 21 is also set lower than the height to the lower surface of the thick edge portion 13. Further, since a gap of about 1 mm is formed between the edges 28 of the floor panel 1 so as not to generate a rubbing sound, the width of the abutting portion 22a portion of the partition portion 22 is equal to this gap. The length from the side edge 28 to the side side surface part 11b is added.

  In the present invention, the thickness of the high dam portion 19 and the low dam portion 21 is set to be narrower than the width of the neck portion 12. In this case, the diameters of the centers of the two are set to be substantially the same, and when the floor panel 1 is placed on the platform 9, the inner periphery and the outer periphery of the high weir portion 19 are the inner periphery (the standing portion 27) of the neck portion 12. ) And the outer periphery (corner side surface portion 11a). This is because the high weir portion 19 is inserted into the neck portion 12 without any trouble even if the width of the neck portion 12 is wide due to the difference in the thickness of the steel plate of the floor panel 1.

  In addition, in the present invention, the vertical rib 30 that can take a large deformation amount is formed as a deformation portion on the inner periphery of the high weir portion 19. The vertical rib 30 is formed integrally with the high dam portion 19, and when the inner periphery of the neck portion 12 interferes with this, the vertical rib 30 is deformed so that the high dam portion 19 can be inserted into the neck portion 12. Yes. The vertical ribs 30 are scattered on the inner periphery of the high dam portion 19 and are formed radially toward the center of the low step portion 10, and about 2 to 4 pieces are provided in one high dam portion 19. Are preferable (two in this example). The longitudinal ribs 30 are formed in a radial shape by causing the longitudinal ribs 30 to vertically contact the inner peripheral surface of the neck 12 (the outer peripheral surface of the upright portion 27) formed in a four-radius circle shape following the low step portion 10. The reason is that the longitudinal ribs 30 are less likely to be damaged as compared with the case where they are subjected to compressive deformation and are subjected to bending deformation by being brought into contact with each other at an angle. The reason why the number is two is that it is necessary at least for rotational deviation.

  Next, as to how to place the floor panel 1 on the support leg 3, if the nut 7 is moved up and down to adjust the platform 9 to a predetermined height, the sides on both sides of the floor panel 1 with the lower step portion 10 interposed therebetween. The bottom surface 15 is placed on the mounting portion 20 by pushing into the lower step portion 10 side until the side surface portion 11b comes into contact with the abutting portions 22a on both sides sandwiching the high dam portion 19 respectively. Subsequently, the abutting portions 22a on both sides sandwiching the high dam portion 19 of the support leg 3 are pushed into the floor panel 1 side until they abut on the side surface portions 11b on both sides sandwiching the low step portion 10 of the floor panel 1, respectively. 15 is placed on the mounting portion 20 and the support legs 3 are bonded to the foundation floor 2. As a result, the movement of the floor panel 1 toward the lower step portion 10 is restricted by the abutting portion 22a, and the neck portion 12 is always fitted into the high weir portion 19 in a regular positional relationship, and the upright portion 27 is vertically ribbed. 30 abuts and deforms. For this reason, the upper end corner of the vertical rib 30 is formed in a chamfered taper portion, and the rising portion 27 is easily fitted. 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 4 is fitted into the lower step portion 10 and screwed into the screw support 6, the outer periphery of the trunk portion 17 descends while sliding on the inner periphery of the cylindrical barrel portion 23 of the platform 9. The misalignment and deformation of each other are regulated, and the head 16 enters the low step portion 10 and presses the low step portion 10 on its back surface. Even in this case, in many cases, the back surface of the low step portion 10 is not in contact with the receiving surface portion 18 of the platform 9, and the low step portion 10 is pressed downward in an elastically deformed state. Is in a fixed state. At this time, the panel retainer 4 has an effect of easily and reliably deforming the vertical ribs 30 by the tightening force and reliably preventing the floor panel 1 from being lifted by the original restoring force of the vertical ribs 30. Therefore, even if the rigidity of the vertical rib 30 is high, it can be easily deformed, and the position regulating force of the floor panel 1 can be set higher.

  By the way, the floor panel 1 is classified into a wide type and a narrow type, and the wide type and the narrow type are described above. Even in this case, the diameter of the low step portion 10 and the length from the low step portion 10 to the corner side surface portion 11a are set to be the same, but according to this, the inner and outer widths of the neck portion 12 are different. Specifically, on the inner peripheral side of the narrow neck 12, the upright portion 27 approaches the corner side surface portion 11 a and becomes narrower, but on the outer peripheral side, the area of the bottom surface 15 placed on the mounting portion 20. In order to ensure, normally the position does not change.

  Therefore, the thickness of the high dam portion 19 and the protruding amount of the vertical rib 30 are such that in the wide type, the tip of the vertical rib 30 is in contact with the upright portion 27 on the inner peripheral side and somewhat interferes, and is high on the outer peripheral side. A standard in which a predetermined gap is secured between the weir portion 19 and the corner side surface portion 11a is set as a standard. In this case, in the narrow type, the upright portion 27 greatly interferes with the vertical ribs 30. Even in this case, however, there is still a gap with the inner periphery of the high dam portion 19, and the high dam Sufficient rigidity is ensured in the portion 19, and only the vertical rib 30 is deformed so that the neck portion 12 is inserted into the high dam portion 19. In addition, instead of the vertical ribs 30, for example, a plurality of vertical ribs protruding ends may be connected to form a hollow protrusion-like deformed portion. In short, the deformable portion can be deformed by pressure interference from above the neck portion 12, and the shape is not limited as long as the deformable portion has an appropriate strength for regulating the horizontal position of the floor panel 1.

  Accordingly, when the gap between the high weir portion 19 and the upright portion 27 due to manufacturing errors is small, the deformation (collapse) of the vertical ribs 30 is large, and when the gap is large, the collapse of the vertical ribs 30 is only small. There is no problem in inserting the neck 12 into the high weir 19. Then, the presence of the vertical ribs 30 having corresponding rigidity prevents the floor panel 1 from attempting to be displaced. Since a corresponding gap is formed between the outer periphery of the high dam portion 19 and the corner side surface portion 11a, the size of the gap of the neck portion 12 due to a wide and narrow type or manufacturing error is absorbed, and the neck portion 12 is absorbed. Is inserted without interfering with the high weir portion 19.

To summarize the above, the relationship between the width of the neck 12 and the amount of deformation (collapse) is as shown in Table 1 below (if the difference in plate thickness between the narrow and wide steel plates is small, a manufacturing error will occur. It is possible that the amount of deformation reverses due to the above). In short, even when the width is the narrowest, the vertical rib 30 is crushed to allow the neck 12 to be inserted into the high weir portion 19, and even when the width is the widest, the vertical rib 30 is crushed even slightly, and the vertical portion 30 and the vertical portion 27 are vertically There is no gap between the ribs 30 that causes displacement.

  FIG. 4 is a plan view showing a laying state of a floor panel using a support leg according to another example of the present invention, and FIG. 5 is a cross-sectional view taken along line A′-O-A of FIG. The abutting part 32a is provided on the side surface of the pin-like projecting part 32 which is separated from the high dam part 19 and is erected from the placing part 20 on a diagonal line passing through the center of the mounting board 9 and the center of the high dam part 19 It is. Along with this, a positioning hole 31 is formed at a position where the pin-like protrusion 32 on the bottom surface 15 of the floor panel 1 exists. Therefore, when the floor panel 1 is placed on the mounting board 9, the pin-shaped protrusions 32 and the positioning holes 31 are put together in an inserted state.

  At this time, the pin-like protrusions 32 have a triangular shape whose outer peripheral side opens 90 ° in plan view, and the apexes coincide with the diagonal lines of the floor panel 1. Along with this, the positioning holes 31 are formed in a quadrangle in which the diagonal lines coincide with the diagonal lines of the floor panel 1. And the hole side surface part 31a is bend | folded upwards as a positioning side surface part on the adjacent two sides by the side of the inner periphery of the positioning hole 31, and when placing the floor panel 1, the hole side surface part 31a is made into the pin-shaped projection part 32. It is placed so as to be along the abutting portion 32a provided on two adjacent sides on the outer peripheral side. At this time, a gap is secured between the two adjacent sides on the outer peripheral side of the hole side surface portion 31 a located on the opposite side and the pin-like projection portion 32 in order to facilitate insertion. This facilitates the operation of placing the floor panel 1 on the platform 9. In addition, as in the above example, the floor panel 1 and the support leg 3 can be easily and surely fitted in a regular positional relationship, and the floor panel 1 can be moved to the lower step side. The rotational deviation in the horizontal plane is restricted. As the abutting portions 32a are provided at a distance from each other, the effect of preventing rotational deviation can be enhanced. The points and functions of the vertical ribs 30 are the same as described above.

Although it is A sectional drawing, the thing of this example is an example which integrally formed with the mounting board 9 by the aluminum die-casting in the part equivalent to a receiving board and a nut, Furthermore, it replaces with a vertical rib and is from separate soft rubber etc. The elastic body 33 is the same as the example shown in FIGS. The elastic body 33 in this case has a simple structure in which a rectangular rubber piece having a predetermined thickness provided with an adhesive layer on one side is attached to the inner periphery of the high weir portion 19. The effect of absorbing the size of the gap of the neck portion 12 due to the wide and narrow types of the floor panel 1 and manufacturing errors within the range is the same as the above-described vertical rib, and in order to smoothly fit the neck portion 12, The upper end corner of the body 33 is similarly formed as a chamfered taper. Further, the elastic body 33 may be formed in a cap shape so that the elastic body 33 can be mounted on the high dam portion 19. If it does so, the positioning at the time of attaching the elastic body 33 will become easy, and the effect which prevents peeling at the time of the elastic body 33 deform | transforming by interference of the neck part 12 can be anticipated.
