Description

[Detailed description of the invention] A. Purpose of the invention (1) Industrial application field The present invention relates to a floor wiring crossing device.

(2) Conventional technology When performing floor wiring, there are times when it is necessary to cross different types of wiring on the wiring route, and conventionally it has been necessary to cross different types of wiring when crossing such wiring. In order to prevent contact, for example, a plurality of first direction passageways and a plurality of second direction passageways orthogonal to these are partitioned by a separator provided on a frame disposed on the floor. , has already been proposed (Jikko 55-
(See Publication No. 14030).

(3) Problems to be solved by the invention However, in the above-mentioned conventional device, the separator fixed to the floor is arranged so as to always cover the lower second direction passageway. If it is difficult to pass the wires through the passageway, and if the wiring in each passageway is to be connected to each other at the intersection of the first and second direction passageways, it is necessary to insert the wiring through the separator each time. It is necessary to drill holes, which is cumbersome work.

The present invention has been proposed in view of the above, and an object of the present invention is to provide a floor wiring crossing device that can solve the above problems of conventional devices.

B. Structure of the Invention (1) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a support frame fixed to a bottom plate to form a frame disposed on the floor. a plurality of first separators for defining a plurality of first direction communication paths parallel to each other along one direction between the lid and the bottom plate; A plurality of second separators for defining a plurality of mutually parallel second direction passageways orthogonal to the passageways between the lid and the bottom plate are erected on the bottom plate so as to be perpendicular to each other, and The lower half of each first separator and the upper half of each second separator are cut out at the intersection of the first and second separators to avoid mutual interference between the two separators.
A partition member is selectively disposed to vertically partition a plurality of first flat passages each connected to the directional passageway and a plurality of second flat passages respectively connected to the second directional passageway, and each partition member is selectively disposed. , a plate-shaped body interposed between vertically adjacent portions of each of the first and second flat passages, and a pair of adjacent first separators that extend upward from the plate-shaped body and can be inserted and removed. and a pair of legs extending downward from the plate-like main body and fitting removably between a pair of adjacent second separators. Features.

(2) Effect When the partition wall member is set, the first direction passageway and the second direction passageway which are perpendicular to each other can be vertically isolated from each other at the intersection thereof, so that the wiring in the first direction passageway and the Mutual contact with the wiring in the two-way path can be reliably prevented.

Furthermore, in the state before the partition wall member is set, the first
Since the overlapping portion of the directional passageway and the second directional passageway, that is, the first and second flat passages, can be opened upward, the task of passing wires through the second flat passageway on the lower side is particularly easy. This can be done easily and accurately by workers while checking visually.

Furthermore, the work of setting the partition member can be carried out by simply fitting the guide portions and the leg portions between the corresponding separators. After the partition wall member is set, the movement of the partition wall member in the vertical and horizontal directions can be restricted by the above-mentioned fitting effect.

Furthermore, the partition wall member only needs to be installed between the vertically adjacent portions of each of the first and second flat passages, where isolation is particularly necessary.
At the intersection where the partition wall member is not installed, the wires in the first and second passageways can be connected to each other without having to specifically drill through holes in the separator.
