DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a structural panel used for OA floors, curtain walls, and other uses.

[0002]

2. Description of the Related Art In computer rooms, hospitals, broadcasting studios, and the like, a double floor structure is used for storing wiring of equipment or storing ducts. The double floor is to lay a new floor panel on the floor of the building to secure storage space for wiring and ducts. It can be easily removed in preparation for changing the layout of equipment, and the floor strength and dimensions Stability is required.

Conventionally, a double floor constructed on an existing floor includes:
In many cases, aluminum or steel die-cast floor panels are combined, and each panel is supported on supporting legs.

[0004]

By the way, when a floor panel made of aluminum or steel die-casting is used, a double floor having high strength, excellent dimensional stability, and hardly causing deformation such as warpage can be realized, but the weight is large. There is a limit to weight reduction. In addition, a curtain wall requires dimensional stability, especially flatness, in addition to being lightweight. Further, in a curtain wall or the like, flatness is required in addition to lightness.

An object of the present invention is to provide a structural panel which is excellent in pressure resistance and dimensional stability and can be reduced in weight.

In order to achieve the above object, a structural panel according to the present invention is a structural panel having two or more layers of structural plates between a pair of face plates, wherein the structural plates are rigid panels, and are arranged in a row or column direction. Each section has a hexagonal shape with dense arrangement , and each section has a regular hexagonal projection that rises on one surface of the plate surface at the same rising height. The protruding portion has a flat top portion, a hollow portion opened on the other surface, and a gap having the same interval is formed between each side of the protruding portion in each of the adjacent sections, and the structural plate of each layer is In this case, two or more layers are stacked so that one section of a layer is relatively evenly spread over three sections of another layer.

Further, the hollow portions of the projections of the respective sections adjacent to each other are provided.
The parts communicate with each other through grooves in ridges formed on the plate surface so as to straddle each section, and the ridges increase the strength of the structural plate.
The groove is a filling that fills the hollow part of each projection.
The filling space of the wood is also of the.

Further, a pair of structural plates is provided between the face plates, and the structural plates of each pair are joined such that the top planes of the projections face each other.

Further, the top plane of the projections provided on the structural plate, has a small hole leading to the hollow portion, the small hole, which is for the protrusion and out of the layers communicate with each other, collision of the layers Between clubs
It serves as an inlet for the filler to be filled into the gap and the hollow portion of the projection .

[0010]

The structure plate is a rigid panel such as a thin steel plate or a synthetic resin plate. The protruding portions in each section are formed by shaping the plate surface to rise to one surface. Since the phases of the projections rising in the respective hexagonal sections of the plate surface are shifted in the row or column direction, the projections are blocked by the projections and do not easily deform. When the protruding parts are opposed to each other and the pair of structural plates are overlapped so that each protruding part is in uniform contact with the three protruding parts on the other side, the load applied from one surface of the panel is dispersed. As a result, the pressure resistance is improved. The same operation and effect can be obtained even when the pair of structural plates are overlapped with the hollow side of the protrusion facing each other.

[0011] Between the structural plates of each layer and between the structural plate and the face plate,
Adhesive or welding is used to bond together, but after bonding, if filler such as foam or inorganic hollow beads is filled inside and outside the protrusions of each layer through small holes opened in each protrusion, the impact applied to the panel can be reduced. The resistance to the compression force is further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a double floor panel will be described below with reference to the drawings. FIG. 1 shows an example of a double floor panel according to the present invention. The floor panel of the embodiment shows an example in which the structural boards 3 and 3 are interposed between the front panel 1 and the rear panel 2 in two layers.

The structural plate 3 is a thin steel plate and, as shown in FIG. 2, divides the plate surface into a regular array of dense hexagons. D for each section
Section D is formed vertically and horizontally on the plate surface with a phase shift in the row or column direction, and a regular hexagonal projection 4 that rises on the plate surface at the same rising height by pressing is formed in the section D. It was done. As shown in FIG. 3, a hollow portion 5 opened on the other surface is formed in the protrusion 4. The sections D, D are densely arranged, and the gaps δ having the same interval are formed between the protrusions 4, 4,... In the adjacent sections D, D.

The top of the projection 4 is flat, and a small hole 6 is opened at the center of the top. When stacking structural plates,
As shown in FIG. 4, the protruding portions of the plate surfaces are butted against each other,
And the projection 4a of the first-layer structural plate 3a and the second-layer structural plate 3
b and the projections 4b of one layer are shifted from each other, and the projections 4a of one layer are replaced with three projections 4b, 4b, 4b of the other layer, as shown in FIG.
4b, the layers are evenly straddled and laminated, and the structural plates 3a, 3
The front surface plate 1 and the back surface plate 2 are attached to the surfaces on the side of the hollow portions 5a and 5b, respectively.

The face plates used as the front plate 1 and the back plate 2 are not particularly limited, and inorganic board, foam concrete, wood board and other floor base materials can be used. As vinyl tile,
Attach the tile carpet.

Since the structural plate 3 has the regular hexagonal projections 4 in each section D in a dense arrangement, each projection 4 has a large bending strength against the bending stress. Since the structural plates 3a, 3b are stacked in two layers, each of which is evenly in contact with the three protrusions 4b, 4b, 4b of the other layer, the load can be dispersed and the surface strength can be increased.

In FIG. 6, each protrusion 4a of one structural plate 3a is replaced with three protrusions 4b of the other structural plate 3b.
4b, the small holes 6 on each protrusion 4a relatively form the protrusions 4b, 4b on the other structural plate 3b.
4b, the three sides of the laminate are sealed, and a filler M such as a foam material or an inorganic hollow bead is injected from one open side, and the protrusions 4b, 4
The filler is filled into the hollow portions 5 of the protrusions 4a and 4b through the gaps between the holes b and the small holes 6 to form a panel having a solid structure, and the resistance to impact and compressive force can be further increased.

FIGS. 7 (a) and 7 (b) show that a ridge 7 protruding from one side of the plate surface is formed on each side of each ridge over each section D, and a groove 8 in the ridge 7 is formed. This is an example in which the hollow portions 5 of the protrusions 4 adjacent to each other are communicated with each other. According to this structure, the ridges 7 serve as ribs to increase the strength.
The filling material M can be easily filled in each projection 4 through the inner groove 8.

In the case of a floor panel, it is effective to use a filler to provide a solid structure because the increase in weight does not become a particular problem. No material is used.

In the embodiment described above, the example in which the pairs of the structural plates 3a, 3b are combined by abutting the protruding portions 4a, 4b is described. However, the pairs of the structural plates are combined with the hollow portions 5, 5 facing each other. Specifications are conceivable. If necessary, three or more structural plates can be laminated to obtain the required strength.

[0021]

As described above, according to the present invention, since the structural plates having regular hexagonal projections are used in the densely arranged sections, the bending strength of each structural plate is large, and
Since two or more structural plates are laminated with the protrusion of one structural plate straddling the three protrusions of the other structural plate, a concentrated panel can be effectively dispersed to obtain a structural panel having a large surface strength. Can,
In addition, a pressure-resistant filler is injected and hardened into the gaps between the hollow portions of the projections and between the projections to improve the integrity, thereby further improving the impact resistance and the pressure resistance.

As the structural plate, a hard synthetic resin plate can be used in addition to the thin steel plate. However, by drawing the thin steel plate, the strength can be increased and the weight of the structural panel can be reduced. Further, according to the present invention, it is possible to combine not only flat panels but also curved structural panels, which can be applied to floor panels, curtain walls, other interior materials, and large-diameter pipes of containers. Since it can be provided with heat insulation, it has an effect that it can be widely used for various heat insulation, structural panels such as heat insulation boards and cooling tanks.
