TECHNICAL FIELD OF THE INVENTION
The present invention belongs to the technical field of a structure in which an edge guide is attached to an outer peripheral portion of a floor panel forming a free access floor on a concrete floor of a building, and a floor panel for a free access floor having the edge guide.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a configuration of a floor panel forming a free access floor, a structure in which a top plate and a bottom plate that are vertically stacked are joined and integrated has been widely known (for example, Patent Documents 1 to 3 and 6, 7).
The joining method of the top plate and the bottom plate in the floor panel panel having the above configuration is roughly classified into a method of spot welding a contact portion between the top plate and the bottom plate, and a method of caulking.
[0003]
There are also known a type in which a synthetic resin tile is attached as a surface finishing material on an upper surface plate of a floor panel, and a type in which a carpet or the like is used without a finishing material. The tile-attached floorboard panels are further broadly classified into a type in which an edge guide is attached to the outer peripheral edge of the panel (for example, Patent Documents 1 and 2) and a type in which an edge guide is not provided (for example, Patent Documents 3 and 4). FIG. 5 shows the construction of a free access floor using floor panels with edge guides.
In the drawing, reference numeral 1 denotes a support leg fixed to a concrete floor of a building, and 2 denotes a panel receiving plate. The illustrated floor panel is supported at its four corners by the panel receiving plate 2 of the support leg 1. Reference numeral 3 denotes an edge guide attached to the outer peripheral edge of each floor panel, and reference numeral 4 denotes a tile. As illustrated in FIG. 6, the edge guide 3 is made of a material obtained by extruding a synthetic resin into a U-shaped cross section, and has the same thickness as the tile 4.
[0004]
Patent Literature 1 discloses a floor panel panel in which an edge guide is attached to an outer peripheral edge, and a carpet is laid as a surface finishing material on an upper surface of an upper plate surrounded by the edge guide.
Patent Literature 2 discloses an edge guide in which edge guides attached to an outer peripheral edge of a floor panel are joined by heat welding to be integrated.
[0005]
Patent Literatures 3 and 4 disclose floor panel panels in which an upper surface plate and a bottom plate are overlapped and joined by caulking and integrated.
Patent Literature 5 discloses a method in which two superposed thin plates are joined by caulking. The gazette discloses a method in which two superposed thin plates are deeply drawn by a crushing action and joined by crimping, and a method in which once deep drawn is swaged back to the original plate surface and flattened. A method is also disclosed.
FIG. 1 (b) of Patent Document 6 particularly describes an example in which a peripheral side wall of a bottom plate is partially recessed and a caulking joint is formed at that portion.
Patent Literature 7 discloses an intersection-fixed type free access floor in which intersections of floor panel panels whose four corners are supported by support legs are fixed by fastening with set screws.

[Problems to be solved by the invention]
As a method of manufacturing a floor panel, a method in which a superimposed top plate and a bottom plate are joined by caulking and integrated is a multiple of the production speed in a single pressing process compared to a method in which this is performed by welding. fast. Therefore, from the viewpoint of the production cost, the production method by caulking is definitely performed advantageously.
[0008]
A plurality of hemispherical projections are provided in a fixed arrangement on the bottom plate of the floor panel panel as shown in Patent Documents 3 and 7 as means for securing the rigidity and thickness of the floor panel panel. The caulking joint in such a floor panel is performed not only at the contact point between the apex of each protrusion and the top plate, but also at the overlapping portion of the flange portion formed flat on the outer periphery of the bottom plate and the top plate. . When a floor panel with four corners supported on the support legs, so to speak, is subjected to an overload, the largest load is applied to the periphery of the panel, especially the flanges near the four corners supported by the panel support plate of the support legs. . For this reason, a large number of spot portions spaced at a relatively small pitch are caulked and joined to the portion to secure strength and structural stability.
[0009]
In normal caulking, as shown in FIGS. 4 and 5 of Patent Document 4, for example, as shown in FIGS. 4 and 5 of Patent Literature 4, deep drawing caulking is performed so that the superimposed top plate and bottom plate swell downward. To achieve a strong bond. Therefore, although the bonding strength is sufficiently high and the structural stability is high, as a result of the deep drawing bonding, “projections” bulging about 1 mm to 2 mm downward from the lower surface of the bottom plate are generated. When the “projection” is generated on the flange portion, it may become an obstacle when the edge guide having the U-shaped cross section is fitted to and attached to the outer peripheral edge portion of the panel.
[0010]
As a countermeasure, a processing method in which the position of the caulking joint (projection) is deviated by a necessary dimension inward from the outer peripheral edge of the floor panel panel so as not to hit the edge guide may be considered. However, this floor panel panel with an edge guide is manufactured using a stamping die common to a floor panel panel of a so-called intersection fixed type, and flange widths at four corners of the floor panel panel are formed to be narrow. That is, as shown in FIG. 7, the support leg for supporting the floor panel panel of the intersection fixed type has a cross-shaped flange receiving portion 2a that divides a circle into four parts in a plan view on the panel receiving plate 2. It is a formed configuration. As illustrated in FIG. 8, in the floor panel panel of the intersection fixing type, the flange portions F ₁ and F _{2 of} the two adjacent floor panel panels P ₁ and P ₂ are connected to the width dimension w of the flange receiving portion 2a (about 10 mm). ) Is supported with a half width. In the floor panel P ₁ , P ₂ , the vertical peripheral side wall C that is continuous with the flange portions F ₁ , F ₂ closely adheres to the side surface of the flange receiving portion 2 a, and does not cause a horizontal shift motion. It is configured. As a result, the form of the four corners of the non-fixed type floor panel with edge guides is also manufactured in the same manner as the intersection fixed type floor panel for convenience of manufacture, and only the four corners of the panel are flanged. Are narrowly limited. With such a narrow flange portion, there is almost no room for selecting the processing position of the caulking joint, and the projection of the deep drawing caulking becomes an obstacle when fitting the edge guide to the outer peripheral edge of the panel and attaching it. There is a problem that can not be avoided.
[0011]
Therefore, an object of the present invention is to adopt a method of caulking for manufacturing floorboard panels, which has a high manufacturing speed and is advantageous in terms of manufacturing cost. An object of the present invention is to provide an edge guide mounting structure of a floor panel for a free access floor and a floor panel which are devised so as not to hinder the mounting of the guide.

[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a mounting structure of an edge guide of a floor panel and a floor panel according to the inventions described in claims 1 to 4 will be described with reference to the drawings.
1 to 4 show an embodiment of a floor panel 10 in which an edge guide 3 is attached to the entire outer periphery of four sides to form a free access floor.
[0017]
In this floor panel 10, a flat top plate 6 made of a thin steel plate and a bottom plate 5 having the same outer peripheral shape as the top plate 6 and having a flat flange portion 5B in a peripheral portion are overlapped and integrally joined. Consisting of The bottom plate 5 has a peripheral side wall 5C which is bent substantially vertically downward continuously to the flange portion 5B inside the flange portion 5B. In the inner part surrounded by the peripheral side wall 5C, a plurality of protrusions 5A having an inner radius of about 26 mm and having an upward hemispherical shape are formed in a staggered arrangement with a pitch of about 70 mm. The hemispherical projections 5A increase the strength and rigidity of the floor panel 10 and give the panel an appropriate thickness feeling.
[0018]
The top plate 6 and the bottom plate 5 are integrally joined by swaging, which is excellent in production speed without using any welding. Specifically, first, each contact point between the top plate 6 and the top of the protrusion 5A of the bottom plate 5 which comes into contact with the top plate 6 is moved from the top plate 6 to the bottom plate 5 as shown in a sectional shape in FIGS. And are integrally connected by a deep drawing caulking 8 (so-called bulging type caulking). Therefore, at the top position of the projection 5A having a hemispherical shape, a projection swollen by the caulking joint 8 is generated downward.
[0019]
Next, the overlapping portion of the above-mentioned flange portion 5B of the bottom plate 5 and the upper surface plate 6 is also crimped and joined to a large number of spot portions at appropriate intervals over the entire circumference of the four sides of the floor plate panel 10 to form an integral connection. Is being done. However, caulking of this portion is performed in the following two kinds of contents, roughly classified into a bonding position and a range.
[0020]
(Type 1 caulking)
As is clear from FIG. 1, the flange portion 5B around the bottom plate 5 (outward from the peripheral side wall 5C) constituting the floor panel 10 is located near four corners of the floor panel 10 (about 70 mm from the corner to the side). The length of the flange portion 5B is formed to be narrow (about 10 mm), and the width of the flange portion 5B other than that (an intermediate portion excluding the above range) is relatively wide (the widest portion is about 20 mm). ing. The reason is as described in the above paragraph number 0010. Therefore, the caulking joint formed into the narrow flange portion 5B near the four corners of the floor panel 10 can reduce the diameter of the projection (usually about 4 mm) generated by the caulking or shift the position of the caulking joint inward. It is very difficult to secure the fitting depth (at least about 2 mm) required for mounting the edge guide 3 on the outer peripheral edge of the panel even if efforts are made to position the edge guide 3. On the other hand, as illustrated in FIG. 5, the floor panel 10 requires a large bonding strength for the caulking joints 11 in the above-described range because the four corners are supported by the panel receiving plate 2 of the support leg 1. Is done.
[0021]
Therefore, the two caulked joints 11 in FIG. 1 at the flanges near the four corners of the floor panel 10 are, as shown in detail in FIG. 2A and FIG. The flattening process (so-called flat type) is performed by pushing back to the bottom position of the flange portion 5B. The flat-type caulked joint 11 does not generate a projection like the swollen-type caulked joint 8, and the bottom surface position of the flange portion 5B is maintained as it is. Therefore, regardless of the diameter of the caulked joint 11 or the position of the caulked joint 11, there is no obstacle when the edge guide 3 is fitted to the outer peripheral edge and attached. Of course, the flat type caulking joint 11 does not require post-processing such as polishing after processing.
[0022]
(Second kind of caulking)
Next, the caulking joint 8 in the wide flange portion 5B other than the vicinity of the four corners (the middle part of the side) of the floor panel 10 is made to shift the caulking joint position inward as much as possible. It is possible to secure the fitting depth (at least about 2 mm) required for attachment at the outer peripheral edge of the panel. Therefore, as shown in FIG. 2C, the deep drawing is performed as a crimping joint 8 from the upper plate 6 to the bottom plate 5 (the invention described in claim 3).
[0023]
Further, according to the embodiment shown in FIG. 1, the peripheral side wall 5C of the floor panel 10 has a wide flange portion 5B except in the vicinity of the four corners when viewed two-dimensionally (from the bottom) as shown in FIG. The peripheral side wall 5 </ b> C of the portion that is continuous with is formed in a wavy state inward and outward. As a result, there are many places where the width of the wide flange portion 5B is as large as about 20 mm in a wide place. Therefore, as shown in FIG. 1, the caulking joint 8 processed into the wide flange portion 5 </ b> B has a portion where the peripheral side wall 5 </ b> C is deeply recessed inward so that the edge guide 3 fitted to the outer peripheral edge of the panel does not abut. 2 (c), and as shown in the cross-sectional shape in FIGS. 3 and 4, it is processed as a deep drawn caulked joint 8 (bulging type) from the top plate 6 to the bottom plate 5 (claim) Invention described in Item 4). This caulking connection has the same structure as the caulking connection 8 between the top plate 6 and the top of the projection 5A of the bottom plate 5.
[0024]
Even if the projections are generated downward with a size of, for example, about 6 mm in diameter by the above-mentioned caulking joint 8, as shown in FIG. 2, the fitting depth required to attach the edge guide 3 to the outer peripheral edge of the panel (at least (Approximately 2 mm), and there is no hindrance in fitting and attaching the edge guide 3 to the outer peripheral edge of the panel.
[0025]
In short, the caulking joint 8 of the wide flange portion 5B of the bottom plate 5 is a swelling type deep drawing caulking joint 8 from the upper surface plate 6 toward the bottom plate 5 at a portion where the edge guide 3 fitted to the outer peripheral edge of the panel does not contact. The upper plate 6 and the bottom plate 5 are strongly and integrally connected.
[0026]
(Temporary fixing)
In addition, as a pre-process of a process of integrally joining the upper plate 6 and the bottom plate 5 by the two types of caulking joints 8 and 11, the upper plate 6 and the bottom plate 5 are indicated by reference numeral 12 in FIGS. 1 and 2. The four corners of the panel are temporarily fixed in spots in advance. Specifically, as shown in the sectional shape of FIG. 2 (b), the temporary fixing 12 is provided with a pilot hole at a corresponding position of the upper surface plate 6 in advance, and a corresponding portion of the bottom plate 5 is provided with the pilot hole. This is a structure in which the projection is simply stopped by pushing the upper surface of the upper surface plate 6 so that no protrusion is generated. Although this temporary fixing 12 is processed in a range where the edge guide 3 to be fitted to the outer peripheral edge of the panel comes into contact (see FIGS. 1 and 2), no projection is generated. It does not become an obstacle. Since the top plate 6 and the bottom plate 5 are simply stopped at the four corners by the above-mentioned temporary fixing 12, the work of loading and positioning the caulking machine into the mold can be accurately and quickly performed by an automatic machine. .
[0027]
As described above, the edge guide 3 having a U-shaped cross section can be fitted to the floor panel 10 as shown in FIGS. It is used as a floor panel with an edge guide for building a free access floor.
[0028]
【The invention's effect】
The floor panel panel edge guide mounting structure and the floor panel panel according to the first and second, third, and fourth aspects of the invention and the floor panel panel can be manufactured at a high manufacturing speed and are extremely advantageous in terms of manufacturing cost. Caulking can be employed. Nevertheless, there is no obstacle in fitting and mounting the edge guide having the U-shaped cross section, which is a disadvantage of the caulking connection. Therefore, the floor panel panel of the present invention is provided as an inexpensive edge-guided floor panel panel having edge guides attached to the entire periphery of four sides, and contributes to construction of a free access floor.
ADVANTAGE OF THE INVENTION According to this invention, it is excellent in intensity | strength and structural stability, and can provide the floor panel panel with an edge guide with low manufacturing cost.
