Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a floor material laid on a floor so that a communication cable or the like can be wired.

2. Description of the Related Art Conventionally, floor materials laid so that communication cables and the like can be laid on a concrete floor panel by supporting four corners of a floor panel made of a synthetic resin with leg posts are known.

Problems to be Solved by the Invention However, conventionally known flooring materials have a relatively thick floor panel formed and are relatively heavy, which is inconvenient to transport and handle, and are flame-retardant, but have encountered fires and the like. At times, there is a defect that a large amount of harmful gas is generated.

Therefore, the present invention provides a floor member made of a thin steel plate to make it nonflammable, lightweight, and excellent in mechanical strength.

Means for Solving the Problems That is, the present application is an upper piece made of a thin steel sheet comprising a floor panel and a pair of left and right support members, wherein the floor panel is provided with a square-shaped upper plate provided with a downwardly directed peripheral piece. And a core piece made of a thin steel plate formed such that grooves having a trapezoidal cross section are alternately arranged in an upward and downward direction alternately, and a left and right upward piece which overlaps a peripheral piece of the upper piece on a rectangular lower plate. And a lower piece made of a thin steel sheet provided with front and rear side pieces, respectively, and a lower piece made of a thin steel plate. The supporting member has an L-shaped cross section and is overlapped on both lower side edges of the floor panel. The leg support is provided upright at the front and rear positions of the plate. Preferably, in the above, the left and right side pieces of the lower piece are slightly set in order to easily and densely fit the upper piece and the lower piece. Incline outward, and slightly inward the peripheral piece of the upper piece that overlaps with it. A screw having a leg support and a rotation operating part at the upper end so that the horizontal level of the floor panel can be adjusted even after the floor member is laid. The screw shaft is screwed to the receiving plate, and holes are formed at the four corner positions of the floor panel so as to face the rotation operating part of the screw shaft. In this case, preferably, the lower end of the screw shaft is formed. Then, a grounding piece is rotatably attached to the grounding piece, and the grounding piece is made of synthetic resin.

Action The floor panel is supported by a pair of left and right support members, and a large number of floor panels are laid in this state on a floor board made of concrete to form a floor.

In the above, the leg support is constituted by a screw shaft having a rotation operation part at the upper end, and this is screwed to the receiving plate, and the rotation operation part of the screw shaft is provided at four corner positions of the floor panel. When opening the facing hole, after laying the floor panel via the support member, engage the tool with the rotary operation part of the screw shaft from the vertically penetrating hole, and rotate this The horizontal level of the floor panel can be adjusted.

Examples Hereinafter, examples of the present application will be described in detail with reference to the drawings.
In the present application, a plate-shaped upper piece (1), a core piece (2), and a lower piece (3) are formed by vertically overlapping and bonding, for example, a square having a side of 500 mm. It comprises a floor panel (4) and a pair of left and right support members (6), (6) having leg posts (5), (5) at the front and rear ends.

The upper piece (1) is formed, for example, by bending four peripheries of a thin steel plate having a thickness of about 0.35 mm downward to form a square upper plate (1) a having a side of 500 mm, and a peripheral piece (1) b. Preferably, as shown in FIG. 2, the peripheral piece (1) b is slightly downwardly inclined inward, and holes (7) are provided at four corner positions of the upper plate (1) a. Are drilled respectively.

The core piece (2) is formed by continuously forming a thin steel plate of, for example, about 0.3 mm so that upward and downward grooves having a trapezoidal cross section are alternately juxtaposed by, for example, cold gate processing. A square square shape of 500 mm, the height of which is approximately equal to the height of the peripheral piece (1) b;
Holes (8) are formed at the four corner positions. Further, the lower piece (3) is formed by bending four peripheral edges of a thin steel plate of, for example, 0 and 45 mm upward, respectively, and forming the left and right edges and the front and rear edges of a square lower plate (3) a having a side of approximately 500 mm. In addition, it preferably includes left and right side pieces (3) b whose height is substantially equal to the height of the peripheral side piece (1) b, and front and rear side pieces (3) c whose height is shorter than that. The left and right side pieces (3) b and the front and rear side pieces (3) c are slightly upwardly and outwardly inclined, and holes (9) are formed at four corner positions of the lower plate (3) a.

Each part (1), (2), (3) configured in this way
Are left and right side pieces (3) in the direction of the trapezoidal groove on the lower plate (3) a
The lower side (2) b of the core piece (2) is superposed such that the upper side b faces the upper side, and the upper side (2) a of the core side (2) is superposed on the inner surface of the upper plate (1) a. The superposed portion is adhered with an adhesive, and the outer surface of the peripheral side piece (1) b is superposed on the inner surfaces of the left and right and front and rear side pieces (3) b, (3) c, whereby the floor panel (4) is formed. The holes (7), (8), and (9) communicate with each other in the vertical direction.

The pair of support members (6), (6) are, for example, 1, 6 m
A turning operation part (5) a consisting of, for example, a hexagonal hole at the upper end and a lower end part at the front and rear positions of a receiving plate (10) having a length of approximately 500 mm by bending a steel plate of Preferably, it is formed by screwing leg supports (5), (5) comprising screw shafts each having a grounding piece (5) b made of, for example, synthetic resin rotatably connected thereto,
A pair of left and right support members (6) configured as described above,
(6) On the floor panel (4), the above-mentioned floor panel (4) is bridged, and the upper ends of the leg posts (5) face the corresponding holes (9), respectively.

Thus, the floor material of the present application comprising the floor panel (4) and the pair of support members (6), (6) is similar to the conventional one.
Many are laid on a concrete-finished floor panel, and a carpet or other facing plate is stretched on a floor panel (4).

Then, when the horizontal level of the floor panel (4) is adjusted after the floor member is laid on the floorboard, a tool is inserted into the holes (7), (8), and (9) communicating vertically. This is performed by engaging the turning operation part (5) a of the screw shaft (5) and turning the screw shaft (5).

In the above description, the front and rear and left and right side pieces (3) b, (3) of the lower piece (3) are provided on the inner surface of the peripheral piece (1) b of the upper piece (1).
It goes without saying that the outer surface of c may be polymerized.

Effect of the Invention As described above, in the present application, since the floor panel is made of a thin steel sheet, and the core piece is interposed in the middle, it is lightweight, has excellent mechanical strength, is nonflammable and has excellent durability The floor material can be provided, and in particular, the left and right side pieces of the lower piece are slightly inclined outward, and the peripheral piece of the upper piece that overlaps with this is inclined slightly inward, so that the inner surface of the left and right pieces is When the peripheral pieces are superimposed, the upper piece and the lower piece can be easily and tightly fitted, and the leg support is constituted by a screw shaft having a rotating operation part at the upper end. When this is screwed into the receiving plate and holes are formed at the four corners of the floor panel so that the rotary operation part of the screw shaft faces, the floor panel is laid even after the floor material is laid. The horizontal level can be adjusted, and when the contact piece is made of synthetic resin, the cushion effect is It has advantages such as being obtained.
