2. Description of the Related Art Conventionally, as a floor plate of a multi-storey parking lot, as shown in Japanese Utility Model Publication No. 2-49287, Japanese Utility Model Publication No. 5-854, or (a), a striped steel plate is laid on a joist. (B) paneled with expanded metal fixed to joists, (c) panelized concrete floorboard, (d) pressed steel sheet, (e) standing with some cuts in the steel sheet The one that is raised to increase the rigidity is used.

The floor boards of the above (a), (b), (c), (d), and (e) are not limited to the multistory parking lot, but can be used in the actual construction 63-15.
It is also used as an inspection corridor for high places, a sidewalk, a temporary scaffold, and a tread for outer stairs, as disclosed in Japanese Patent No. 1504, Japanese Utility Model Publication No. 3-16992, Japanese Unexamined Patent Publication No. 4-93465. However, each of these has its own drawbacks,
It was not satisfactory.

First, the striped steel plate of (a) is heavy and difficult to handle, lacks rigidity, has a low anti-slip effect, and is disadvantageous in terms of cost, and is made of expanded metal of (b). Has a major drawback that it can be seen from below, the concrete panel of (c) is high in cost, heavy in weight and has a problem in handling, and (d) and (e) have a drawback that noise is apt to be seen from below. Have.

In addition, a wire mesh plate made of expanded metal or the like is generally used in many cases as in the above-mentioned publications, and it can be seen from below, oil drops, and the cooling water for the car cooler There are many shortcomings due to the mesh, such as leakage and exposure to rain. It should be noted that concrete products are heavy, and pressed products also have the same drawbacks as described above, and since a long cross-linking distance cannot be obtained, a large amount of intermediate joists are required.

[0006]

The present invention has been made for the purpose of solving the above problems.
It is relatively lightweight, has rigidity, is non-slip, has no see-through from below, does not fall or leaks to the bottom, and is highly workable as well. It is intended to provide a double floor board.

[0007]

[Means for Solving the Problems] As a result of extensive studies in order to achieve the above object, a mesh plate is fixed on a shallow U-shaped steel plate formed by bending both sides of a flat plate. It has been found that a double floorboard having a gap between the flat plate and the mesh plate is very suitable.

That is, according to the present invention, a double floor plate is characterized in that a mesh plate is fixed to the upper part of a shallow U-shaped steel plate having low raised edges on both sides of a flat plate, separated from the flat plate at a predetermined height. It was found that excellent results can be obtained by using a welded wire mesh or a deformed iron wire mesh as the mesh plate.

The present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view of an embodiment of the floorboard of the present invention. FIG. 2 is a front view of the embodiment shown in FIG. As shown in these figures, the present invention is one in which a mesh plate (3) is fixed to the upper part of a shallow U-shaped steel plate having raised edges (2) on both sides of a flat plate (1) by, for example, welding. .

That is, this floor plate has a double structure having a double structure of a flat plate (1) made of steel and a mesh plate (3) stretched at a predetermined height from the flat plate (1). It is a floorboard. In addition, (4) in the drawing is a hole for a bolt for attaching to a joist (small beam or pillow beam).

A steel plate having a thickness of 1.6 to 3.2 mm can be suitably used as the flat plate (1) in the present invention, and the size thereof is a frontage (front width) of 200 to 400 mm and a depth of 1000 to 1.
500 mm is preferable, and the height of the raised edge (2) is 30 to
About 60 mm is desirable, and it is preferable that the raised edge (2) is formed by continuously bending the flat plate (1) by bending.

As the mesh plate (3) in the present invention, a welded wire mesh is most preferably used. For example, steel rods having a thickness of 4 to 8 mm are arranged in parallel at intervals of 20 to 40 mm and 100 to 20.
The mesh plate (3), which is formed by arranging columns arranged at 0 mm intervals in a lattice by welding, is excellent. If the deformed iron wire mesh formed by using the deformed iron wire having an irregular cross section instead of the round bar is used as the mesh plate (3), the anti-slip effect is significantly improved and a very excellent result is obtained. Will be used.

The mesh plate (3) and the U-shaped steel plate are fixed to each other by
The mesh plate (3) may be attached by welding in a state of being bridged between the upper portions of the left and right raised edges (2), or both sides of the mesh plate (3) may be bent downward to form the raised edge (2) and the inside. It may be attached by contacting or circumscribing and fitting.

FIG. 3 is a perspective view showing a usage state of the floorboard of the present invention. FIG. 4 is a partial perspective view showing a part of FIG. 3 in an enlarged manner. As shown in these figures, the floorboard of the present invention is a joist (H).
Installed side by side on top of the bridge and bolts (5)
Is inserted into the bolt hole (4) and the bolt hole of the joist (H), and screwed with a nut from below.

The present invention is as described above, in which a mesh plate is laid on a shallow U-shaped steel plate, and a floor plate having a double structure consisting of a flat plate and a mesh plate, in which a groove is provided. Since there is a hollow cavity like this, there is no such idea at all in the past, and the welded wire mesh used as a mesh plate was only used for reinforcing concrete, and it is unexpected to use it for such a floor plate. It is judged as a big thing.

[0016]

EXAMPLE A U-shaped steel plate having a height of a raised edge of 50 mm, a frontage of 300 mm and a depth of 1,500 mm was prepared by bending both sides of a steel plate having a thickness of 2.3 mm, and bolt holes were formed at both ends. On the other hand, diameter 6
Welded wire mesh with a grid spacing of about 30 mm x 147 mm is created by welding with a steel rod of mm, and the width is about 295 mm x depth 1500 mm.
The size of

The above-mentioned welded wire mesh was fixed by welding inside the upper end of the raised edge of the U-shaped steel plate. The obtained double floor board is very suitable as a floor board of a multi-storey parking lot or a step board of the outer stairs, there is no see-through from the bottom, it is possible to prevent objects from falling and liquid leakage, and not to slip and to make a quiet footstep, Moreover, it is light and rigid, has excellent workability, and the cavity in the floorboard can be used for piping and wiring.

[0018]

Next, the effects and uses of the present invention will be described. First, make a list of the effects. a. Since there is a flat plate, there is no see-through from below, and there is no drop of objects or leakage of liquid such as oil or cooling water. b. It also prevents rainwater and can be used as a ceiling.

C. It is relatively lightweight and stiff, and thus a relatively long cross-linking distance is obtained. d. Noise such as footsteps generated on the mesh plate is cut off by the flat plate, so the noise is small. e. It has a large anti-slip effect and is safe. The safety is further improved by using a mesh plate that uses a deformed iron wire mesh.

F. The cavity in the floorboard can be used for piping and wiring, and this cavity can also be used for a duct box. g. Further, this groove-type cavity has a good drainage property and can be used as a kind of gutter, and the cavity can suppress the surface temperature. h. Since it is panelized and lightweight, it is advantageous in construction, and it is sufficient to stop them side by side.

Next, items of use will be described. I. Floor boards for self-propelled or other multi-level parking lots. B. Corridor for inspection and inspection (supply piping is possible). C. Drain gutter lid floor, gutter lid material (becomes a double gutter). D. Floor material for rooms that require plumbing. E. Footboard of the outer stairs (water does not collect on the footboard). F. Used as a ceiling material with the back facing (hang things on a mesh plate). G. Floorboard for clean room (part of flat plate is perforated to suck air). J. Floating pier floor plate (it does not easily slip when wet and the surface does not get hot).

As described above, the floorboard of the present invention exerts various excellent effects, and therefore has a very wide range of applications and exhibits extremely high usefulness as a new construction material.
