Hereinafter, each embodiment will be described in detail with reference to the accompanying drawings. In addition, in the accompanying drawings, for ease of viewing, a plurality of parts having the same attribute may be given only some reference numerals.

FIG. 1 is a plan view of a floor wiring structure 1 according to an embodiment. FIG. 2 is a four-sided view showing a single unit of the floor base 10. FIG. 3A is a perspective view showing an arbitrary floor base 10 through which the X-direction line rail 30 passes. FIG. 3B is a perspective view showing an arbitrary floor base 10 through which the line rail 30 in the Y direction passes. FIG. 4 is a diagram showing the floor base 10 of FIG. 3A viewed in the X direction. 3A and 3B, for convenience of description, the illustration of another floor base 10 provided adjacent to the illustrated floor base 10 and a part of the line rail 30 (on the side far from the floor base 10). Illustration of continuous portions) is omitted.

In FIG. 1, two orthogonal directions (X direction and Y direction) are illustrated. The XY plane corresponds to the horizontal plane, and the floor surface extends in the horizontal plane. The floor surface is the surface of a floor base (not shown) made of concrete or the like, but may be the surface of a floor plate that can be provided on the floor base.

The floor wiring structure 1 includes a plurality of floor bases 10 (an example of a floor forming member). A plurality of floor bases 10 are provided so as to be spread over the entire floor surface to be constructed. In FIG. 1, among the plurality of floor bases 10, the floor base 10 in which the wiring is housed below is shown in relatively detail, and the floor base 10 in which the wiring is not housed below is a simple rectangle or is not shown. Has been done.

Hereinafter, unless otherwise specified, the configuration of one floor base 10 in which wiring is housed below will be described.

The floor base 10 has a wiring accommodating function of forming a space (a space) in the lower side for accommodating wiring with respect to the floor surface, and also has a new floor surface (an upper floor surface of the double floor) that replaces the floor surface. It has a floor function to provide.

Floor base 10 includes an upper surface portion 12 and leg portions 14 as shown in FIG. 2. The floor base 10 has appropriate strength and rigidity capable of ensuring the above-mentioned floor surface function.

The upper surface portion 12 extends above the floor surface in the horizontal plane. The upper surface portion 12 has a rectangular shape (in the present embodiment, a square shape as an example) in a top view, and defines the outer shape of the floor base 10.

The legs 14 are supported on the floor. A plurality of legs 14 are provided. In this embodiment, nine are provided as an example. Specifically, the floor base 10 has four partitioned square portions 11A to 11D, and each of the portions 11A to 11D has a leg portion 14 at each of four corners. At this time, each of the parts 11A to 11D has a common leg portion 14 at a corner of the four corners adjacent to the other part. In this case, the floor base 10 has a total of nine legs 14. In other words, the floor base 10 has nine legs 14 in total, one at each of the four corners of the floor base 10, one at the midpoint of each side, and one at the center. The number and the arrangement of the leg portions 14 are arbitrary, but it is desirable that the leg portions 14 have symmetry in arrangement.

The floor wiring structure 1 further includes a line rail 30 (an example of a wiring housing member), as shown in FIGS. 3A and 3B. The line rail 30 realizes a groove structure (pit performance) that suppresses the freedom of movement of the routed wiring. Specifically, the line rail 30 includes a bottom portion 32 and side portions 34 provided upright on both sides of the bottom portion 32 (both sides in a direction perpendicular to the longitudinal direction of the line rail 30). As shown in FIG. 4, the bottom portion 32 and the side portions 34 on both sides of the bottom portion 32 form a C-shaped cross-sectional shape (a cross-sectional view as seen in the longitudinal direction of the line rail 30) with an open upper side, and the wiring is formed. A space (C-shaped groove) 70 capable of accommodating is formed.

The line rail 30 has an elongated form having a predetermined length in the longitudinal direction, and has an equal cross section in a cross sectional view as seen in the longitudinal direction. A plurality of types of line rails 30 may be prepared with different lengths. However, in this embodiment, the line rail 30 has the female engaged portion 38, and the engaged portion 38 may be provided over the entire longitudinal direction, or may be provided only in a part thereof. Good. In the latter case, the line rail 30 does not have an equal cross section as a whole when viewed in the longitudinal direction, but has an equal cross section in the section where the engaged portion 38 exists and the engaged portion 38 does not exist. The section is of equal cross section. The engaged portion 38 has a convex shape when viewed in the longitudinal direction of the line rail 30, has an opening below, and an engaging portion 42 of a cross plate 40 described later is engaged through the opening.

Here, when the engaged portion 38 is provided along the longitudinal direction of the line rail 30, the engaged portion 38 divides a plurality of types of wirings in the corresponding line rail 30 (intersection in the longitudinal direction). It can also function as a partition plate that divides in the direction of Specifically, as shown in FIG. 4, the engaged portion 38 partitions the space 70 extending in the longitudinal direction into two spaces 71 and 72. In this case, a plurality of types of wirings can be spatially divided and arranged such that the space 71 accommodates the electric system wiring and the space 72 accommodates the data system wiring.

The line rails 30 are arranged in a layout according to the layout in which wiring is arranged. Typically, a plurality of line rails 30 are used, some line rails 30 are arranged linearly, and some other line rails 30 are arranged linearly. Below, the straight line (line) formed by the line rails 30 arranged in a straight line is also referred to as a “wiring housing line”. In FIG. 1, the line rail 30 (wiring accommodating line) is schematically indicated by a double line in a manner of seeing through the floor base 10. In the present embodiment, as an example, as shown in FIG. 1, some line rails 30 (an example of the first wiring accommodating member) are linearly arranged in parallel with the X direction, and some line rails 30 are provided. (One example of the second wiring accommodating member) is arranged linearly in parallel with the Y direction. Several line rails 30 arranged linearly in parallel to the X direction are provided in a plurality of sets so as to be separated in the Y direction, and some line rails 30 linearly arranged parallel to the Y direction. Are provided in a plurality of sets in such a manner that they are separated in the X direction. Note that the number and arrangement of the line rails 30 to be used are determined according to the area of the floor surface to be constructed and the layout of wiring.

The line rail 30 can pass through a space below the upper surface portion 12 of the floor base 10. Specifically, the line rail 30 can extend into the space below the upper surface portion 12 of the floor base 10 via the legs 14 of the floor base 10. For this purpose, the outer shape of the gap (entrance) between the legs 14 of the floor base 10 in a side view is larger than the cross-sectional shape of the line rail 30 (the cross-sectional shape viewed in the longitudinal direction), and It is set so as to conform to the cross-sectional shape of.

Here, in the present embodiment, the floor base 10 can cooperate with the line rail 30 to accommodate wiring below, as shown in FIGS. 3A and 3B. The wiring may be housed below the floor base 10 even in a range where the line rail 30 does not extend. In this case, although the pit performance by the line rail 30 cannot be used, wiring can be arranged in an oblique direction or in a curved shape.

By the way, since the floor base 10 is spread over the floor surface as described above, it is convenient for the user if it is possible to easily identify from the exterior which floor base 10 the wiring is accommodated under. Become. From such a point of view, preferably, the floor base 10 has an identification feature on the upper surface portion 12 so that it is possible to easily distinguish between the one in which the wiring is housed below and the other in which it is not. Since the upper surface portion 12 is a visible portion when the floor base 10 is installed, the upper surface portion 12 has the identification feature, so that the user can install the floor base 10 in which the wiring is accommodated below and the wiring below the wiring. It is possible to easily distinguish the floor base 10 that is not housed from the outside. Such identifying features are arbitrary but are, for example, color or transparency. In the case of color, the floor base 10 itself in which the wiring is accommodated below may be colored with a predetermined color, or a sheet or the like having a predetermined color is attached to the upper surface portion 12 of the floor base 10 in which the wiring is accommodated below. You may be asked. For example, when a colored sheet is attached to the floor base 10, the sheet can be peeled off, so that it is possible to flexibly respond to a change in wiring after the fact. Further, in the case of transparency, similarly, the floor base 10 itself in which wiring is housed below may be formed of a transparent material, or the upper surface portion 12 of the floor base 10 in which wiring is housed below is transparent. A sheet or the like may be attached. For example, when a transparent sheet is attached to the floor base 10, the sheet can be peeled off, so that it is possible to flexibly respond to a change in wiring after the fact.

According to the floor base 10 having such an identification feature, when adding or changing wiring wiring, the current wiring condition is determined without removing the floor base 10 (without lifting the floor base 10 from the floor surface). ) I can understand.

Next, the configuration of the cross plate 40 will be described with reference to FIGS.

FIG. 5 is a perspective view showing one floor base 10 at an intersecting portion (P portion in FIG. 1) of a wiring accommodation line formed by the line rail 30 in the X direction and the line rail 30 in the Y direction. FIG. 6 is a two-sided view of the cross plate 40.

The floor wiring structure 1 preferably further includes a cross plate 40 (an example of an end holding member). The cross plate 40 is provided at a location where the wiring accommodation lines formed by the line rails 30 intersect (see P portion in FIG. 1 and FIG. 5). The cross plate 40 holds the ends of the four line rails 30 that form the intersection by the engagement between the engaging portion 42 and the engaged portion 38 described later.

The cross plate 40 is provided for one of the four partitioned square portions 11A to 11D. That is, the line rail 30 in the X direction and the line rail 30 in the Y direction form an intersection below one of the four partitioned square portions 11A to 11D in the floor base 10, The cross plate 40 is provided for the intersection. The cross plate 40 is placed on the floor surface, and the line rail 30 is placed on the cross plate 40.

As shown in FIG. 6, the cross plate 40 has a main body 41 that is substantially rectangular in a top view, and a male engagement portion 42 that engages with the engaged portion 38 of the line rail 30. The engaging portion 42 is provided so as to project upward. In the modification, the engaged portion 38 may be a male type and the engaging portion 42 may be a female type.

With respect to one cross plate 40, four engaging portions 42 are provided, two extending in the X direction and two extending in the Y direction. As shown in FIG. 6, the four engagement portions 42 extend from each side of the main body 41 and have a cross shape in a top view. The two engaging portions 42 in the X direction may be realized by one continuous engaging portion 42, or the two engaging portions 42 in the Y direction may be one continuous engaging portion 42. May be realized by

According to the present embodiment, as described above, by using the line rail 30 and the floor base 10 in combination, it is possible to increase the degree of freedom in wiring wiring while ensuring pit performance. That is, since the line rail 30 forms a C-shaped groove, the pit performance can be secured by the line rail 30. The Y-direction pitch of the X-direction line rails 30 corresponds to the Y-direction pitch of the arrangement of the floor base 10 (to be precise, the Y-direction pitch between the leg portions 14), and the Y-direction line rails 30. Since the pitch in the X direction corresponds to the pitch in the X direction of arrangement of the floor base 10 (more accurately, the pitch in the X direction between the leg portions 14), the line rail 30 can be arranged with a relatively high degree of freedom. Further, since the layout of the line rails 30 can be determined in such a manner that the line rails 30 pass below the floor base 10, it is easy to change the layout afterwards, and the degree of freedom in wiring can be increased.

Further, according to the present embodiment, since the line rail 30 and the floor base 10 are separate bodies, it is possible to add the line rail 30 or remove (change the position of) the line rail 30 to perform wiring. It is possible to increase the degree of freedom in the installation of.

Further, according to the present embodiment, since the resin floor base 10 itself has a floor surface function (because it has relatively high strength and rigidity), a steel groove lid or the like is unnecessary, and recyclability is improved. To do.

Further, according to this embodiment, since the cross plate 40 is provided, the line rail 30 can be stably held. Further, since the engaging portion 42 and the engaged portion 38 extend in the longitudinal direction of the corresponding line rail 30, the cross plate 40 and the line rail 30 are in the longitudinal direction of the line rail 30. Can be combined with some deviation along. As a result, dimensional errors and placement errors of the line rail 30 can be easily absorbed at the location of the cross plate 40, and the workability of placement of the line rail 30 is improved.

Next, with reference to FIG. 7, a method for forming the floor wiring structure 1 (construction method) will be outlined.

FIG. 7 is a diagram showing a schematic process of the method for forming the floor wiring structure 1.

In step S90, the worker arranges the line rail 30 on the floor according to the wiring layout. At this time, the line rails 30 are held by the cross plates 40 at the points where the line rails 30 intersect. That is, at this time, the line rail 30 is provided so as to cover the cross plate 40 at the intersection of the line rails 30, and the engaged portion 38 is engaged with the engaging portion 42.

In step S92, the worker arranges the wiring while inserting the wiring in the line rail 30.

In step S94, the operator arranges the floor base 10 on the floor so that the line rail 30 passes through the space below the upper surface portion 12.

Thus, according to the present embodiment, the floor wiring structure 1 can be formed by a simple process using the line rail 30.

In the above-described embodiment, the floor base 10 and the line rail 30 form an example of a floor wiring structure set. The floor wiring structure set may further include the cross plate 40.
