Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner-cutting floor plate, a corner-cutting wiring groove using the same, and a method for forming a lid for a crossing thereof.

[0002]

2. Description of the Related Art A wiring floor with a wiring groove has been frequently used in recent years. Conventionally, a grid-shaped wiring groove that simply crosses in a cross shape has been used as a wiring path. At the intersections of the crosses, there are some where the corners of the floorboard are rounded, but the radius of curvature is usually about 5 mm, and the sharp corners are eliminated, so a narrow wiring groove with a width of 5 to 10 cm. There is a lot of trouble in bending and wiring the cord at a right angle. Especially in the case of a hard cord, the situation was such that it could not be bent.

[0003]

OBJECTS OF THE INVENTION The present invention solves these difficulties,
Wiring groove for easy wiring of cords and floor boards that enable it
Another object of the present invention is to provide a method for forming a lid at the intersection of wiring grooves.

[0004]

To this end, according to the present invention, a corner-cutting floor plate is formed by obliquely cutting a corner of the floor plate facing a crossroad where wiring grooves intersect. Further, a corner cutting wiring groove is installed in which the corner cutting edge of the corner cutting floor plate is directed toward the center of the intersection. Further, at the intersection of the corner cutting wiring grooves, a substantially octagonal intersection surrounded by four corner cutting floor plates is formed, and a cover plate that substantially matches the octagon is formed.

[0005]

With this structure, it is similar to driving a car when a corner is cut at a corner of a road, and wiring work becomes easy when a cord is bent at an intersection and wiring capacity increases. .

Embodiment 1 FIG. 1 shows a corner floor plate 1. A square face plate 10 made of a galvanized steel plate having a thickness of 2 mm and having a side of 30 cm is provided with a corner cut point 11 which is located at a distance of 5 cm from each corner, and a corner cut point of both corners. The surface plate is cut into a pentagon along the corner cutting edge 12 connecting the two. The corner cut length is about 7 cm. The five sides of the pentagonal face plate 10 are bent at a right angle downward by 3 cm to form the support legs 13. The lower edge of the support leg 13 is provided with two arch-shaped openings 14 on the wide side and one on the narrow side.

As shown in FIG. 2, four corner-cutting floorboards 1 are abutted around the corner on the side opposite to the corner-cutting side 12 so that the floorboard group A
To form. A large number of such floor board groups A are arranged on each of the four sides other than the corner cut side with a space of 10 cm width,
Lay out on the floor. The space between the floor plate groups serves as the wiring groove 2. An octagonal intersection 3 surrounded by eight corner cut points 11 is formed where the wiring grooves intersect with the cross shape.

FIG. 3 shows a support 4 made of a galvanized steel plate having a thickness of 2 mm. Long sideways,
The upper end of the supporting surface 41 having a height of 2 cm is bent into a crank shape, and is continuous with a horizontal supporting shelf 42 having a width of about 5 mm, and a side wall 43 having a height of 2 mm is formed upward.
Is attached.

As shown in the figure, the support 4 is joined by welding or the like along the corner cutting edge of the corner cutting floor plate and the two supporting legs 13 on both sides of the corner cutting edge. In this case, the lower end of the support tool and the lower end of the support leg should be aligned. An insertion groove 44 surrounded by the support leg 13, the support shelf 42, and the side wall 43 is formed at the upper end portion of the support tool.

FIG. 4 shows the groove lid 5. A rectangular zinc-plated steel plate with a thickness of 3 mm, a length of 25 cm, and a width of 11 cm is bent, and the edges of about 5 mm are bent downward at right angles, leaving the surface plate 10 with a width of 10 cm. A toe 51 is attached. From the lower ends of the locking edges 51 on both sides in the center of the surface plate 10 in the longitudinal direction,
And a narrow cut 52 is provided. This way,

Therefore, the groove lid 5 can be provided with some flexibility.

As shown in FIG. 5, the groove lid 5 is placed over the gap between the corner floor plates 1 to complete the wiring groove 2. In this case, the locking edges 51 on both sides of the groove lid are inserted and fixed in the insertion grooves at the upper end of the support tool 4 attached to the support legs 13 of the corner floor plate. Surface plate 10 and surface plate 10 of surrounding floor plates
Is formed with a flat surface. The groove lid is fixed by the insertion groove, and the interval between the wiring grooves is defined by the width of the groove lid, and the deviation can be prevented, so that a stable wiring floor is formed.

FIG. 6 shows the cross lid 6. A surface plate 10 made of a zinc-plated steel plate having a thickness of 3 mm, which fits in an octagon formed by sequentially connecting eight corner cutting points of an intersection formed by four corner cutting floor plates. Is the main body. The area around the surface plate 10 has a width of about 1 which corresponds to a wiring groove.
A groove edge 61 of 0 cm and a corner cutting edge 62 having a width of about 7 cm corresponding to the corner cutting side of the corner cutting floor plate are alternately arranged.

The four corner cutting edges 62 of the surface plate 10 are extended in a strip shape of about 5 mm with the width of the corner cutting edges being extended, and the extending portions are bent downward at right angles to form the locking edges 51. The four locking edges are inserted into the insertion grooves of the above-mentioned support provided on the four corners facing the intersection, and the intersection lid is fixed on the intersection. The face plate is formed in the same plane as the face plates of the surrounding corner floor plates. As with the corner cutting edge, the groove edge may be bent to provide a reinforcing edge.

On the corner cutting edge of the corner cutting floor plate, a supporting shelf having a depth equal to the plate thickness of the lid and having a width of 5 mm or more is provided, while the cross lid is formed of a flat plate and the corner cutting edge is kept as it is. A 5 mm strip that has been extended without bending,
The cross lid may be configured by directly mounting the cross lid on the support shelf.

[0015]

Embodiment 2 FIG. 7 shows another example of the corner floor plate 1. A small block floor board with a side of 5 cm
A square pentagonal floorboard 1 having a substantially pentagonal shape is formed by cutting one corner of a square aggregate floorboard B formed by connecting the above. The deformed block floor boards 15 are arranged along the corners. In addition to this, as the corner cutting floor plate, it is possible to form various types such as a floor plate made of a flat plate body and height adjustable with bolt legs attached at each corner, but at least one corner cutting If so, the material is not specified. Normally, the distance from the corner to be cut to the corner cut point is ideally about one half of the width of the formed wiring groove, but it is about one fifth, that is, a wiring groove having a width of 10 cm. On the other hand, even if it is a corner cut of 2 centimeters, a certain effect can be expected.

[0016]

[Embodiment 3] A large corner cut inevitably results in a large intersection. In the case of a cross lid corresponding to a large intersection, the central portion is weak against the load from above. The other example of the cross lid which reinforced the center part is shown. The center portion of the surface plate is reinforced by a separately prepared reinforcing plate. However, if the lid has a double structure, it is convenient to attach a wiring outlet to the lid in addition to the purpose of reinforcement.

As shown in FIG. 8, two facing corner cutting edges 62 of a face plate 10 made of a galvanized steel plate having a thickness of 3 mm and having a size to be fitted into an octagonal shape of a crossing are formed into two corner cutting edges. The width is about 5 mm and the extension is bent downward at a right angle to form the locking edge 51. A semi-long round notch 63 having a width of 20 mm and a length of 20 mm is provided at the center of the one corner cutting edge 62 having no locking edge.

As shown in FIG. 9, using the same material as above, the width is the same as that of the two corner cutting edges 62 not provided with the locking edges,
A rectangular reinforcing plate 64 is prepared by extending the length of the facing corner edges of the surface plate by about 1 cm. The reinforcing plate is bent downward at the extended portions of both ends to form the locking edge 51 having a height of about 5 mm. A band-shaped cut 52 having a width of 15 mm is provided at the center of the formed locking edge,
Subsequent to this cut, a semi-long circular cutout 63 having a width and length of 15 mm is provided on the surface of the reinforcing plate.

As shown in the drawing, a reinforcing plate 64 is welded to the back surface of a front plate having locking edges provided at two locations to form a cross lid 6. When welding, the side with the locking edge of the reinforcing plate,
Stack on the side of the surface plate that does not have the locking edge. By stacking in this manner, locking edges are attached to all corner cutting edges around the surface plate. Further, since the center of the face plate is doubled, it is strong against a load from above and is convenient for use in a large intersection. The method of using the cross lid is the same as that in the first embodiment.

When the cross lid is formed in this manner, as shown in FIG.
As shown in 0, the large cutout of the face plate 10 is
Overlying the four small notches, a wiring outlet 65 is formed, but at the same time, a narrow horseshoe-shaped mounting edge 66 having a width of about 2 mm is formed around the notch of the reinforcing plate.

A plastic cap 67 having the same thickness as the thickness of the face plate is fitted in the notch of the face plate as shown in FIG. 11, and is put on the mounting edge so that it can be easily attached and detached. It is good to block the wiring outlet. An insertion groove 68 may be formed on the back surface of the cap of the wiring outlet so that the cap is inserted and fixed in the frame edge. Alternatively, a deep cut groove 69 may be provided along the edge of the cap, and a part may be easily cut off by using pliers or the like.

As another example of the cross lid, a face plate having a thickness of 5 is used.
It may be formed by a flat plate having a high rigidity of millimeters, and a separately formed insertion edge having an L-shaped cross section may be attached to the corner cutting edge. Further, as another example of the cross lid, support legs may be attached to the four corner cut edges of the surface plate so as to be at the same height as the surrounding floor plate so that they are directly placed on the floor surface.

[0023]

Since the present invention is constructed as described above, it has the following effects. 1 A wide wiring space can be formed by using a corner-cutting floor plate to form a corner-cutting wiring groove. 2 When bending a hard cord, it is necessary to have a large bending R, but since there is a corner cut, it is possible to obtain a large R even if the wiring groove itself is relatively narrow. 3 In the case of a crossroad with no corner cuts, there was no good way to support it even when trying to put a lid on the crossroads. In the case of the corner cut wiring groove, since the corner cut edge can be supported, an independent lid at the intersection can be formed. 4 If an independent lid can be prepared for the intersection, a wiring outlet can be attached to the intersection lid, and the cord can be conveniently pulled out from the wiring groove.
