【Example】

 Hereinafter, a first embodiment of a double floor panel according to the present invention will be described with reference to FIGS. As shown in FIG. 2, the double floor panel 1 of the present embodiment is configured by combining a plurality of square unit panels 2 into a planar shape. An underfloor wiring groove 3 (wiring groove) is formed in the unit panel 2, and lid members 5 and 6 for closing the underfloor wiring groove 3 are attached to an upper end opening 4 thereof. It has become.

As shown in FIGS. 3 and 4, the unit panel 2 is obtained by integrally molding a resin such as polypropylene. For example, the unit panel 2 is standardized to have a side of 250 mm and a height of about 45 mm. It has a hollow structure. On the upper surface of the unit panel 2, the underfloor wiring groove 3 is formed in a cross shape so as to connect the center positions of the opposite sides to each other, whereby four square divided panel portions 7 are formed. 8 ・ 9 ・ 10 are formed.

The dividing panel portions 7, 8, 9, 10 are, for example, as shown in FIG. 4, a cylindrical support column formed in a box-shaped inner central portion, corner portions and central portions of respective sides. 11 is provided, and a plurality of ribs 12 are formed so as to connect the columns 11. As a result, each of the divided panel portions 7, 8, 9, 10 itself is reinforced and has a rigid structure that is not deformed by an external force. In addition, a rubber seat is provided at the bottom of each column to cushion the impact.

As shown in FIG. 3, the underfloor wiring groove 3 is composed of a bottom plate portion 3 a and a side wall 3 b which is a peripheral edge of the divided panel portions 7, 8, 9, 10. In the bottom plate portion 3a, four L-shaped slits 13 are formed along the peripheral edge of each of the divided panels 7, 8, 9, and 10, and at the end portion of the underfloor wiring groove 3 in the bottom plate portion 3a. A slit 14 along the underfloor wiring groove 3 is formed at the center position in the width direction of the underfloor wiring groove 3. In addition, recessed portions 16 having holes 15 are formed at the four corners of the upper surface of the unit panel, and a connecting member described later is inserted into the recessed portions 16 to enable connection with another unit panel 2. ing.

At the upper end opening 4 of the underfloor wiring groove 3 along the periphery of each divided panel portion 7, 8, 9, and 10, on both sides thereof, as shown in FIGS. 2 to 4, the underfloor wiring groove 3 is formed. A step portion 17 is formed along it. The stepped portion 17 is formed such that the upper surface of the lid member 5 is formed in a level difference with the upper surface of the unit panel 2 when the lid member 5 described later is placed, and the lid member 5 is formed. On the mounting surface 17a on which is mounted is a linear fitting groove 18 along the side surface 3b of the underfloor wiring groove 3. On the inner wall surface 18a of the fitting groove 18, as shown in FIG. 1, a locking projection 19 (locking projection) is provided which projects in the depth direction of the fitting groove 18 and projects in the groove width direction. A plurality of fitting grooves 18 are formed at intervals in the longitudinal direction. The locking projections 19 are alternately arranged on the inner wall surfaces 18a facing each other along the longitudinal direction of the fitting groove 18.

As shown in FIG. 5, the lid member 5 is, for example, a member obtained by coating the entire aluminum plate 5 a with a polypropylene resin 5 b or the like, and is formed on both sides of the underfloor wiring groove 3. It is formed in a strip shape having a width to be stretched over the portion 17 and having a plate thickness accommodated in the step portion 17. On one surface of the lid member 5, there is formed a strip-shaped ridge 20 which vertically projects from the one surface and extends in the longitudinal direction in the vicinity of one long side. The protrusion 20 is formed in a shape that fits into the fitting groove 18 formed in the unit panel 2, and the thickness dimension thereof is a groove at the tip of the locking protrusion 19 of the fitting groove 18. It is formed larger than the widthwise distance.

In addition, a tape-shaped cushioning material 21 is attached along the long side in the vicinity of the long side on the other side of the surface of the lid member 5 where the protrusion 20 is formed. The cushioning material 21 is made of, for example, a material such as felt, and is brought into contact with the mounting surface 17a of the step portion 17 when the lid member 5 is housed in the step portion 17 of the unit panel 2. Thus, the cover member 5 and the unit panel 2 are prevented from coming into direct contact with each other. In this case, the fitting groove 18 may not be provided in the step portion 17 on the side where the cushioning material 21 abuts.

Further, in FIG. 2 to FIG. 4, reference numeral 22 is a slit provided in the divided panel portions 8 and 9 for attaching an upper outlet, and reference numeral 23 is a length arranged around the unit panel 2. A striped border member 24 is a connecting member having four protrusions that fit into the holes 15 formed in the recess 16.

By using the double-floor panel 1 configured as described above, a double floor can be easily configured as follows. First, after laying and adhering a sheet 25 that absorbs fine irregularities on the floor base G, a border member 23 is placed at a predetermined position on the sheet 25, and the unit panel 2 is placed inside the border member 23. The unit panels 2 are connected to each other by laying them in order and fitting the connecting members into the holes 15 of the recesses 16. As a result, the underfloor wiring grooves 3 formed in each unit panel 2 are connected to each other, and the grid-like underfloor wiring grooves 3 are formed.

Next, the slit 22 at a predetermined position is broken, an upconcent is attached to the slit 22, and a predetermined cable is arranged in the underfloor wiring groove 3 (not shown).

After that, the protrusion 20 of the lid member 5 is fitted into the fitting groove 18 formed in the step portion 17 on one side of the underfloor wiring groove 3, whereby the upper end of the underfloor wiring groove 3 is fitted. The opening 4 is closed. At this time, the side surface of the protrusion 20 of the lid member 5 is brought into pressure contact with the locking protrusion 19 formed in the fitting groove 18, and the tip of the locking protrusion 19 is crushed while the fitting groove is crushed. It will be fitted in 18. As a result, the side surface of the protrusion 20 and the inner wall surface of the fitting groove 18 are held with a minute gap therebetween, and it is possible to prevent the two surfaces from making surface contact with each other, and the protrusion 20 is kept inside the fitting groove 18. It will be locked without backlash.

When the protrusion 20 of the lid member 5 is fitted into the fitting groove 18 formed in the step portion 17 on one side, the cushioning material 21 attached to the lid member 5 is attached to the other side. The step surface 17 is brought into contact with the mounting surface 17a. As a result, the cushioning material 21 is sandwiched between the lid member 5 and the mounting surface 17a, and direct contact between the lid member 5 and the unit panel 2 is avoided. Then, in this state, the lid member 5 is completely housed in the step portions 17 formed on both sides of the upper end opening 4 of the underfloor wiring groove 3, and the upper surface of the unit panel 2 and the lid member 5 are covered. A flat floor surface is formed by being flush with the upper surface.

At the intersection 26 of the underfloor wiring groove 3, the lid member 6 can be attached by the same method. As a result, all the upper end openings 4 of the underfloor wiring groove 3 are closed. Then, in this state, by laying a floor finishing material 27 such as carpet on the plurality of unit panels 2 and the lid member 5, a double floor can be formed easily and promptly.

In the double-floor panel 1 of the present embodiment configured as described above, the slits 12 and 13 are formed in each unit panel 2, so that even if the floor base G is uneven, Since the unit panel 2 is slightly deformed at the slits 12 and 13 to have a shape that follows the floor base G, a stable floor structure can be formed without the double floor panel 1 rising. Moreover, the unevenness of the floor base G is also absorbed by the rubber seats provided below the columns 11 of the respective divided panel portions 7, 8, 9, 10.

Further, according to the double floor panel 1 of this embodiment, the underfloor wiring groove 3 is formed between the unit panels 2, and the upper end opening 4 of the underfloor wiring groove 3 is closed by the lid member 5. Since it is designed so that the cable etc. arranged in the underfloor wiring groove 3 can be exposed only by removing the lid member 5, addition, repair, inspection, maintenance, etc. of the cable can be performed. The work of can be carried out. Therefore, as compared with the conventional method in which the panels once spread are peeled off and the above-mentioned work is performed, these works can be performed more easily, and the man-hours required for the work can be significantly reduced.

Moreover, when the lid member 5 is attached to the unit panel 2, the projection 20 of the lid member 5 is fitted while crushing the locking projection 19 formed in the fitting groove 18 of the unit panel 2. Therefore, for example, even if a dimensional variation occurs due to a molding error of the protrusion 20 or the fitting groove 18, the variation is absorbed by the crushing margin of the locking protrusion 19, and the lid member is covered. 5 and the unit panel 2 can always be locked so as to prevent backlash. Further, the locking projection 19 prevents the side surface of the projection 20 of the lid member 5 from coming into surface contact with the inner wall surface of the fitting groove 18, and the cushioning material 21 allows the lid member 5 and the step portion 17 to be in contact with each other. Since direct contact is avoided, an external force that causes relative displacement between the lid member 5 and the unit panel 2 acts when the double-floor panel 1 is stepped on from above the floor finishing material 27. Even in the case, it is prevented that the both are rubbed together. As a result, it is possible to prevent the generation of abnormal noise caused by the sliding of the polypropylene resin.

Next, a second embodiment of the double floor panel according to the present invention will be described with reference to FIGS. 6 to 10. In the present embodiment, the same reference numerals are given to the portions having the same configuration as the first embodiment, and the description will be simplified. As shown in FIG. 7, the double floor panel 30 of this embodiment includes a plurality of square unit panels 31 that are combined in a plane shape and an underfloor wiring groove 3 formed between the unit panels 31. The cover member 5 closes the upper end opening.

The unit panel 31 is formed in a square shape by connecting four panel bodies 32 integrally formed of a resin such as polypropylene by a flexible connecting portion 33. For example, as shown in FIG. 8, the panel body 32 includes a box-shaped panel main body 34 having a standard size of 250 mm on a side and a height of about 45 mm. And a plurality of ribs 36 are formed so as to connect the columns 35 with each other. A grounding protrusion 37 is formed at the tip of the pillar 35 so that the unit panel 31 is brought into contact with the floor base G when the unit panel 31 is spread over the floor base G. In addition, a thin plate 38 extending outward in the horizontal direction is provided in the lower part of the two side faces 34a of the panel body 34 that are not connected by the connecting part 33, and a step part 17 is provided in the upper part.

When the thin plate 38 of another unit panel 31 adjacent to the thin plate 38 is butted to the tip of the thin plate 38, the thin plate 38 and the thin plate 38 are fitted to each other to suppress relative movement in the horizontal direction. 9 and a fitting recess 40 are provided. The thin plate 38 forms the bottom plate portion 3a of the underfloor wiring groove (wiring groove) 3 formed between the panel bodies 34 together with the thin plates 38 of the other unit panels 31.

The step portion 17 is formed in the same manner as in the first embodiment, and the mounting surface 17 a is provided with the fitting groove 18 having the locking projection 19. The lid member 5 is also constructed in the same manner as in the first embodiment.

As shown in FIG. 10, the connecting portion 33 is a U-shaped cord having sufficient flexibility and made of a resin such as polypropylene, and each connecting portion has a minute gap and is adjacent to each other. Two flannel bodies 32 are provided between opposing side surfaces. As a result, even if the connecting portion 33 bends due to the unevenness of the floor base G, the distance between the panel bodies 32 does not interfere with each other. The dimensions of the connecting portion 33 are, for example, about 2 mm in thickness, about 2 mm in width and about 10 cm in length.

By using the double-floor panel 1 configured as described above, a double floor can be easily configured as follows. First, the border member 23 is placed on the sheet 25 laid on the floor base G, and the thin plate 38 constituting one side of the unit panel 31 is brought into contact with the border member 23. Then, the fitting convex portions 39 of the unit panel 31 are fitted into the fitting concave portions 40 of the other unit panel 31, respectively, and both thin plates 38 are butted. By repeating this method in sequence, a plurality of unit panels 31 can be laid flat on the sheet 25, and the underfloor wiring groove 3 can be formed between the panel bodies 32 of the unit panels 31. Then, in the upper end opening 4 of the underfloor wiring groove 3, step portions 17 having a constant step are arranged on both sides along the longitudinal direction of the underfloor wiring groove 3, and are formed in the step portion 17. The fitting groove 18 formed is arranged along the longitudinal direction of the underfloor wiring groove 3.

After that, the protrusion 20 of the lid member 5 is fitted into the fitting groove 18 formed in the step portion 17 on one side of the underfloor wiring groove 3, whereby the upper end of the underfloor wiring groove 3 is fitted. The opening 4 is closed. As a result, the protrusion 20 of the lid member 5 is locked in the fitting groove 18 without backlash. Further, the cushioning material 21 prevents direct contact between the lid member 5 and the mounting surface 17a. Then, in this state, by laying a floor finishing material 27 such as carpet on the plurality of unit panels 2 and the lid member 5, for example, a double floor can be easily and quickly formed.

According to the double-floor panel 1 of the present embodiment, when the floor base G is uneven, the connecting portions 33 are slightly deformed so that the respective panel bodies 32 follow the floor base G. It is possible to form a stable floor structure by making all the ground protrusions 37 at the bottom of each panel body 32 in contact with each other. Further, since the unit panels are spread over each other with the fitting convex portion 39 and the fitting concave portion 40 in the fitted state, it is possible to prevent the unit panels from being displaced from each other.

Further, since the underfloor wiring groove 3 is formed between the unit panels 2 and the upper end opening 4 of the underfloor wiring groove 3 is closed by the lid member 5, the first embodiment is different from the first embodiment. Similarly, work such as cable addition, repair, or inspection / maintenance can be easily performed, and the number of man-hours required for the work can be significantly reduced. Further, similarly to the first embodiment, the lid member 5 and the unit panel 2 can be always locked so as not to cause backlash, and the generation of noise caused by the sliding of the two is prevented. be able to.

The following techniques can be adopted in the double floor panel 1 according to the present invention. After integrally molding each panel body 32, the connection portion 33 is formed by welding the panel bodies 32 at their side surfaces. The spacing, the number, the shape, etc. of the locking projections 19 formed in the fitting groove 18 can be arbitrarily set. Although the locking projection 19 is formed in the fitting groove 18, instead of this, it may be formed on the side surface of the protrusion 20. Although the protrusion 20 is formed in the lid member 5 and the fitting groove 18 is formed in the unit panel 2 or the panel body 32, the arrangement thereof may be reversed instead. The cushioning material 21 is made of felt, but the cushioning material 21 of any other material should be adopted.
