DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the floor panel wiring structure of the present invention will be described below with reference to FIGS. This floor panel wiring structure mainly includes the floor panel 1, the sleeve 5, and the wiring chip 10.

As shown in FIGS. 3 and 4, the floor panel 1 has an upper plate 2 and a lower plate 3 made of an iron plate and has a substantially square plate shape. The upper plate 2 is on the surface side as a floor and is flat. On the other hand, the lower plate 3 is on the back side as a floor, and has a square-shaped outer shell flange portion 3a, a frame portion 3b inside thereof, a step portion 3c inside thereof, and a large number of pieces inside thereof. The dimples 3d, 3d, ... And the reinforcing ribs 3e, 3e ,. Then, the space formed by both plates 2 and 3 is filled with concrete 3f. Specifically, in this embodiment, the thickness is 600 mm □ and the thickness is 34 mm,
Further, the dimples 3d, 3d, ... Have a root diameter of about 55 mmφ, and the lowermost plate 3, which is the deepest part, is in contact with the upper plate 2.

The floor panel 1 is provided with a passage opening 4 at a position that does not cover the outer shell and is suitable for conducting a passage. This passage opening 4 is, for example, as shown in FIG.
As shown in, a hole saw (rotary circular saw) H is used to form a through hole of about 45 mmφ coaxially with the center of the desired dimple 3d. As a result, as shown in FIG. 5B, the inclined curved surface 3e remains on the root side of the dimple 3d. The passage opening 4 may be formed in the shape shown in FIG. 5, or as shown in FIG.
(In this embodiment, the diameter may be about 53 mmφ and the depth may be about 5 mm) to form a stepped shape.

The sleeve 5 is made of a thin metal plate, and as shown in FIG. 1 or 6, a sleeve portion 6 penetrating through the passage opening 4 and a mounting portion 7 having a diameter larger than that of the sleeve portion 6 are coaxial cylinders. And have these as basic parts. Therefore, when the trunk 6 is passed through the wire opening 4 from the upper plate 2 side, the mounting portion 7
Is placed on the upper plate 2 or the stepped portion of the passage opening 4. Specifically, the outer diameter of the body portion 6 is 43 mmφ and the inner diameter of the mounting portion 7 is 53 mmφ. The body 6 has such an axial length that there is a portion corresponding to the inclined curved surface 3g in that state.

The mounting portion 7 has a shallow cylindrical shape in which a peripheral wall 7b is erected from a mounting surface 7a which is connected to an end of the body portion 6 on which a wire passage chip, which will be described later, is mounted, and the mounting portion 7 is arranged in the circumferential direction. Two captive prevention pieces 8,8 having a predetermined length in the center direction are symmetrically connected in series. Specifically, the center angles of the respective fall prevention pieces 8 and 8 are about 80 °, and the tip inner diameter is 47 mmφ. Therefore, the fall-preventing pieces 8 and 8 are like eaves, but they do not extend to the extent that they overlap the inner circumference of the body 6. In addition, the inner surface of the mounting surface 7a and the fall-preventing pieces 8 and 8 has a size that substantially corresponds to the thickness of the wire chip to be described later.

This sleeve 5 is provided with an opening for passage of the body portion 6.
After the mounting portion 7 is placed on the upper plate 2 or the step portion of the wire passage opening 4 by penetrating through the portion 4, the portion corresponding to the inclined curved surface 3g of the body portion 6 as shown in FIG. Is attached to the floor panel 1 by pressing and deforming it so that it comes into close contact with it.

The wire-through chip 10 is made of an iron plate and, as shown in FIG. 1, is composed of two chip pieces 11, 11 each having a substantially semicircular shape. Both chip pieces 11 and 11 have a line-symmetrical shape, and when they are mounted on the mounting portion 7, the outer periphery thereof corresponds to the inner periphery of the mounting portion 7, that is, a shape of a circle having an outer diameter substantially equal to the inner diameter thereof. I am doing it. As shown in FIG. 7, each chip piece 11 has a semi-circular power line notch 12 for forming a perfect circle through which the power line passes, on the side where both chip pieces 11 and 11 abut.
And a semi-oval weak wire notch 13 for forming an ellipse for passing the weak wire. Specifically, both chip pieces
The inner diameter of the power line notch 12 formed by 11, 11 is about 1
3mmφ, the major diameter of the weak wire notch 13 is 18mm, the minor diameter is 6.5.
mm.

Furthermore, the tip pieces 11, 11 are provided with flocking 14 on their surfaces. The bristles 14 are, for example, first sprayed with an adhesive on the surface of the chip piece 11, and then horizontally supporting the chip piece 11 in an electrostatic field. It is dropped, and the flocked material is blown up from the nozzle from below. As a result, the flocked material is applied by the electrostatic action in a direction perpendicular to each surface of the chip piece 11, that is, in a state in which the flocked material stands, and the flocked material 14 is applied.

In the wiring work, one chip piece 11 is fitted into the mounting portion 7 with one of the fall prevention pieces 8 as a reference, and the power line is passed through the power line notch 12 and the weak wire is passed through the weak wire notch 13 while the other is cut off. Insert the chip piece 11 of the other into the mounting part 7 with the other cap piece 8 as a reference, and mount both chip pieces 11 and 11, and then attach both chip pieces 11 and 11 to the cap pieces 8 and 8 at their adjacent parts. Rotate to the position where it overlaps. This allows both chip pieces
11, 11, that is, the wire passing tip 10 is securely attached to the sleeve 5.

The wiring structure of the floor panel is a wiring chip.
Ten positions, that is, the electric wires to be passed are positioned inward of the outer contour of the floor panel 1. In addition, between the through-wire chip 10 and the sleeve 5, between the chip pieces 11 and 11 with the wire pitch 10, and between the wire cutouts 12 and 13 formed in the chip pieces 11 and 11 and the wire that has been wired, etc. Even a slight gap in the area can be closed by the hair transplant 14. This means that when the floor panel 1 also serves as part of the air conditioning duct, it can significantly prevent air conditioning air from leaking, and when you step on it and walk or when the entire floor vibrates. However, it acts so as to prevent the generation of sound, and acts so as to maintain a predetermined positional relationship by frictional force. Moreover, both the electric power line and the weak electric wire can be passed by one wiring chip 10. Further, when the passage opening 4 is provided in the floor panel 1, alignment and opening forming work are facilitated.

Next, a different embodiment of the wiring chip will be described with reference to FIGS. The through-wire chip 20 is also made of an iron plate and, as shown in FIG. 8, is composed of two chip pieces 21, 21 each having a substantially semicircular shape. Both chip pieces 21 and 21 have a line-symmetrical shape, and when they are mounted on the mounting portion 7, the outer circumference thereof corresponds to the inner circumference of the mounting portion 7, that is, a shape of a circle having an outer diameter substantially equal to its inner diameter. I am doing it. Also,
Each chip piece 21, as shown in FIG.
A U-shaped cutout 22 for passing a power line or a weak electric wire is provided on an arcuate outer peripheral portion where 1 does not contact. In particular,
The width of the notch 22 for passing wire is 13 mm. Further, the two chip pieces 21 and 21 are provided with hanging pieces 25 and 25 having a length of about 10 mm, which are continuous with each other on the side where they abut. And these two chip pieces 2
As in the previous embodiment, flocking 14 is applied to the surface of Nos. 1 and 21 as well.

This wire passing work is performed by using one chip piece 21.
While inserting the power line through the passage notch 22 and fitting it into the mounting portion 7 with one of the fall prevention pieces 8 as a reference, and then inserting the other chip piece 21 into the passage notch 22 while passing the power line. Insert the both tip pieces 21 and 21 by fitting them into the mounting part 7 with reference to the fall prevention piece 8 of
Rotate 1 to a position where its adjacent portion overlaps with the fall-preventing pieces 8 and 8. As a result, the two chip pieces 21, 21, that is, the through-wire chip 10, can be securely attached to the sleeve 5.

In addition to the advantages of the previous embodiment, the floor panel wire-carrying structure of this embodiment is such that the sleeve 5 is attached to the arcuate outer peripheral portion where the wire-cutting notches 22 of the chip pieces 21, 21 are formed. By being able to be placed on the portion 7, it is possible to form a notch and reinforce the strength which is slightly lowered. In addition, since the hanging pieces 25, 25 are arranged in series, the strength of the through wire tip 20 against the vertical external force can be reinforced.

In this embodiment, both chip pieces 21, 21 are
Although the notch 22 for passing the wire is dimensioned to pass the power line,
One of them may have a different shape for a weak wire or may have no cutout. Also, attach both chip pieces 21, 21 to the mounting
It is not always necessary to rotate it after it has been attached to, and the hanging pieces 25, 25 also act to prevent falling.

The floor panel having such a wiring structure is
It is laid on the floor together with a floor panel having no passage structure, and a finishing material such as carpet is laid on the upper surface thereof. In this case, if the wire passing tips 10 and 20 project from the floor panel 1, holes are provided in the finishing material corresponding to the outer diameter of the mounting portion 7 of the sleeve 5, and the wire passing tips 10 and 20 are attached to the floor panel 1. For those that do not project from the above, holes will be provided in the finishing material that correspond to the outer diameter of the wire that has been run.

First, in order to ensure that the wiring can be carried out in a good condition, it is not possible to provide the floor panel with dimples, provide a sleeve with a fall-preventing piece, or give hair to the wiring tip. It is not always essential, but the point is that the position of the opening for passage of the floor panel is essential. Further, it goes without saying that the floor panel is not limited to the square shape.

Further, it is not essential that the through-wire chip is composed of a plurality of chip pieces, but it is also possible to form it by one member. In this case, it may be formed in a substantially circular shape and a shape in which the portion that overlaps with the drop-out prevention piece is cut out. Conversely, the number of chip pieces may be three. Moreover, even if it is configured by two chip pieces, both may be asymmetrical. In that case, the notch for the wire passage may be provided only on one chip piece.

In addition, the embodiments and modified examples may be combined appropriately.
