Description

TECHNICAL FIELD The present invention relates to a metal panel member suitable for construction as, for example, a removable floor unit or the like.

2. Description of the Related Art Conventionally, this kind of metal panel member is formed by using two cold-rolled steel plates having a thickness of about 1.0 mm as the front and back metal panels 1 and 2 as shown in FIG. There is.
Of the metal panels 1 and 2, when installed on the floor,
The front metal panel 1 located on the upper side is formed into a substantially flat plate-like rectangular shape, and the other back metal panel 2 located on the lower side is dotted with a large number of circular recesses 3, 3 ... What is formed in a corrugated plate shape by being provided is used. Also, the recess
To give rigidity to the spaces other than 3,3 ... The maximum thickness 33 is achieved by integrally joining the metal panels 1 and 2 at the joining points 5 and 5 by spot welding provided on the
It is formed to have a weight of about 35 mm and a weight per unit area of about 44 kg / m ² .

Further, there is also an assembly in which the recessed portions 3 ', 3' ... Are embossed in the shape of * as shown in FIG. 6, and the others are assembled similarly to the metal panel member shown in FIG.

In the above-mentioned metal panel member, when the reinforcing material such as cement is not filled, there is a flat portion that is continuous from the peripheral portion to the vicinity of the center, so the load strength is low and the strength that can be endured practically cannot be obtained. . Therefore, the reinforcing material such as cement is filled so as to have a load strength that can be practically endured, but the weight per unit area is relatively large and it is inconvenient to handle in construction.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention provides a metal panel member that has a load strength that can be practically endured even when it is not filled with a reinforcing material such as cement, and is less likely to be deformed by a load. To aim.

MEANS FOR SOLVING THE PROBLEMS In a metal panel member according to the present invention, a substantially flat plate-shaped rectangular metal front panel, a metal front panel having the same contour shape as the metal front panel, and a substantially groove-shaped cross section are provided. A ring-shaped continuous ridge is composed of a plurality of metal back panels provided on the plate surface at intervals so as to surround the center point of the plate surface. It is configured by integrally joining the metal front and back panels to each other at a plurality of joining points provided on the plate surface so as to surround the center point of the plate surface.

Action In this metal panel member, the ridge has a side wall portion, and the side wall portion functions as a rib, so that it is difficult to be deformed even when a load is applied, and the ridge has a substantially groove-shaped cross section and is continuous in an annular shape. Are shaped on the plate surface with multiple intervals, so there is no continuous flat part from the peripheral edge to the vicinity of the center, and there are no locally weak parts in the panel as a whole. Even when the reinforcing material is not filled, it has sufficient load strength to withstand practical use and can exhibit sufficient rigidity.

Example The following is a description with reference to FIGS. 1 to 4.

The metal panel portion can be formed by using an inexpensive ordinary steel plate, a galvanized steel plate, or the like. Further, it is preferable to use a vibration-damping steel plate for the floor unit because the intermediate resin film can absorb vibrations and prevent vibrations generated from a plurality of devices installed on the floor surface from being transmitted to other devices.

The panel member consists of two metal surfaces, as shown in Fig. 1.
The back panels 10 and 11 are fixed in contact with each other, and the one metal front panel 10 is formed in a substantially flat plate shape by cutting into a rectangular shape. The other metal back panel 11 has the same contour shape as the metal front panel 10, and a plurality of projections 12, 12 ... It is shaped like a curve. The protrusions 12, 12 ... Are preferably formed in the shape of a square groove having a cross section having side wall portions 12a, 12b ... Or, the side wall portions 12a, 12b.
Can also be formed in a semi-circular shape that draws a gentle curve. Further, it may be formed in an annular shape in plan view, and a plurality of them may be provided at intervals so as to surround the center point of the plate surface.

These metal front and back panels 10, 11 are opposed to each other to form an internal space 13, 13 with the metal front panel 10 and the ridges 12, 12, ... They are joined to each other at the joining points 14, 14 ... By spot welding provided on the plate surface.
The joint points 14, 14 ..., including the outer peripheral flange portion 15,
It is advisable that a plurality of plate surfaces along 2, 12, ... Are provided so as to surround the center point of the plate surface. This plurality of junction points 14,14 ...
Thus, the metal front and back panels 10 and 11 can be firmly and integrally joined.

When the panel member is used as a floor unit, it is preferable that the corners of the metal back panel 11 be bent upright as shown in FIG. Also, when constructing cords and cables from the bottom of the floor unit, the projection 12 should be partially recessed and the outer peripheral flange 15 should be partially notched as shown in FIG. Therefore, the notch 17 can be provided.

The metal panel member thus configured can be constructed as a floor unit by placing a plurality of adjacent panel members. At that time, as shown in FIG. 4, the substantially flat metal front panel 10 is positioned on the upper side and the metal back panel 11 is positioned on the lower side, and they are assembled together. Further, the panel members can be placed under the panel member by using columns 18 on the floor surface of concrete or the like so as to be spaced from the floor surface. As the support column 18, one having a saucer-shaped stopper metal fitting 18a capable of accommodating and locking the protrusions 16 provided at the corners of each panel member can be used. The fastener 18a can be adjusted in height by being screwed into the spindle bolt 18b to support each panel member.

In the construction, since each panel member is formed of only the metal front and back panels 10 and 11, it is relatively light and easy to handle. Also, the ribs 12, 12 ...
Since the side walls 12a, 12b, ... Have ribs, the respective panel members do not deform even when a load is applied.
Each of the ridges 12, 12 ... Has a groove-shaped cross section and is continuously provided in an annular shape. A plurality of ridges 12, 12 ... It is possible to exert rigidity enough to withstand the above load.

Note that a surface material 19 such as a tile or a carpet can be attached to the back surface side of the metal front panel 10. Also, if this panel member is formed of only the metal front and back panels 10 and 11, a load strength sufficient for practical use can be obtained, but especially when a higher load strength is required, cement or the like is reinforced. It is also possible to fill the interior space with material.

As described above, according to the metal panel member of the present invention,
It can be formed as an inexpensive one that is light in weight, hassle-free for construction, and has strength enough to withstand a load.
