Embodiment 1 FIG. 1 shows a small floor plate 10. It is formed by using a galvanized steel sheet having a thickness of 2 mm and a square surface plate 11 having a side length of 14 cm.
Are bent at right angles downward by 5 cm in width to form the support legs 12. At two places at both ends of the support leg, a U-shaped punching portion 13 is provided on the support leg. The width of the punch is 2 cm. A rectangular lid receiving piece 15 connected to the support leg body is formed at the position of the bending line 14 connecting both ends of the punched portion. A connection hole 16 having a diameter of 5 mm is provided at each corner of the support leg 12.

[0007] As shown in FIG. 2, the lid receiving forming piece 15 is punched outward at a required location to form a lid receiver 2 having a substantially L-shaped cross section. The launch width, i.e., the gap between the inner surface of the lid receiver and the outer surface of the support leg, is 2-3 millimeters. The depth from the surface to the bottom of the lid receiver is about 1 cm

FIG. 3 shows a groove cover 3. It is made of a steel plate similar to a small floor plate, has a rectangular shape having a plane shape of 10 cm in length and 8 cm in width, and its surrounding four sides are bent downward at a right angle of 1 cm to form a reinforcing edge 31.

A method of forming a groove wiring type OA floor using a small floor plate and a groove cover will be described. As shown in FIG. 4, the floorboard 1 is formed by combining nine small floorboards 10 vertically and horizontally, that is, a total of nine small floorboards. The small slabs are connected appropriately using the connection holes at the corners of the support legs. The planar shape is a square with a side of about 42 cm. On the support legs facing the outside of the small floor plate 10, a lid support forming piece is punched out to form the lid support 2. Twenty-four lid supports 2 are provided around the composite floor plate 1.

As shown in FIG. 5, floor boards 1 are regularly laid out in front, rear, left and right with wiring grooves 4 each having a length of 8 cm. As shown in FIG. 6, a groove cover 3 is provided on the wiring groove 4 to finish the entire surface flat. When erected, the reinforcing edges 31 on both sides of the groove lid are inserted into the lid receiver 2 formed around the floor plate 1 to stabilize.

As shown in FIG. 7, as a combination of the lid receiver 2 and the groove lid 3, the lid receiver 2 may be formed in a simple horizontal shelf shape. In this case, it is preferable that the lower end of the reinforcing edge 31 of the groove lid 3 is wound inward to finish the lower end flat.

As shown in FIG. 8, a part of the support leg 12 is
The lid receiver 2 may be formed by winding up from the lower end side.

As shown in FIG. 9, the upper corner of the floor plate 1 may be partially cut away, and the upper end of the support leg 12 may be used as the lid receiver 2. In this case, it is preferable that the locking claw 32 is protruded from the groove lid 3 at a position corresponding to the lid receiver.

As shown in FIG. 10, a notch is provided in a part of the support leg 12, and is punched out to form a lid receiver 2 like a bag of a kangaroo belly, which can be inserted into this bag. The locking claw may be formed on the edge of the groove lid.

[0015]

[Embodiment 2] In the above embodiment, an example in which a plurality of small floorboards are combined to form a large floorboard has been described. However, the floorboard may be formed of a single floorboard. As shown in FIG. 11, as in the previous embodiment, a steel plate is used as a basis, and a floor plate provided with supporting legs that stand vertically around the base plate is basically used. In this example, an octagonal floor plate 5 having corner cut sides 51 formed at four corners of a square having a side of 40 cm is used. A reinforcing table 52 having a square upper surface is provided on the lower surface of the floorboard. The reinforcing base is made of the same steel plate as the main body, and is formed to have the same height when the floorboard is laid, and supplements the load-bearing performance of the central part of the surface of the octagonal floorboard.

As shown in FIG. 12, floor boards 1 are laid side by side with wiring grooves 4 having a width of 10 cm. An octagonal intersection groove 41 is formed at the intersection of the wiring grooves. One lid receiver 2 shown in the previous embodiment is attached to each of the corner cut sides 51 of the octagonal floor plate 5. An octagonal groove cover 3 having a shape and size corresponding to the intersection groove is formed. Each peripheral edge of the groove lid is bent downward at a right angle of 1 cm to form a reinforcing edge 31. The octagonal groove cover 3 is erected on the cross groove to finish the surface flat. At the time of erection, the reinforcing edge 31 of the groove lid is inserted into the lid receiver 2 formed at the corner of the floorboard to stabilize.

In the parallel wiring groove, a rectangular groove cover is erected as in the previous example, and the entire surface is flattened.
Complete the A floor.

The floorboard of the present invention is mainly designed to connect small floorboards in advance in a factory or the like to form floorboards in consideration of construction efficiency at the site, but this is not specified.
It is also possible to provide the lid support and the reinforcing edge inserted into the lid support with irregularities or the like that can be fitted to each other so that they can be connected only by being inserted. The support legs may be joined and integrated where they overlap.

Forming the floorboard by combining the small floorboards is advantageous because the small floorboards can be laid down when a regular-size floorboard cannot be used, such as near a wall. When the small floorboards are connected to each other so that they can move freely to some extent, it is convenient for the floor to be laid to be adapted to some unevenness.

The use of an octagonal floor board with corner cuts is convenient because the wiring cords and the like can be easily bent at the intersection grooves and the wiring space can be absolutely widened.

Since the present invention is configured as described above, it has the following features. Since the lid support can be formed by using a part of the side surface of a floor plate made of a rigid thin plate such as galvanized steel plate, it is provided at a very low cost compared to forming the lid support using a separate member. Can be. The shape of the floorboard is very simple and lightweight. Therefore, the cost is low because the production equipment is light and one with good production efficiency can be used. In particular, if the material is omitted using the connecting floor plate, the weight is further reduced and the cost merit is great.
