By using the structural plate 3, bending strength is enhanced, and the centralized load is dispersed to enhance the face strength.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a structural panel used for OA floors, curtain walls, and other applications.

[0002]

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

Conventionally, for a double floor constructed on an existing floor,
In many cases, aluminum or steel die-cast floor panels are combined and each panel is supported on a support leg.

[0004]

By the way, when a floor panel made of aluminum or steel die casting is used, it is possible to realize a double floor which has high strength, excellent dimensional stability, and is resistant to deformation such as warp, but has a large weight. There is a limit to weight reduction. Further, in the curtain wall, in addition to being lightweight, dimensional stability, especially planar accuracy is required. Further, in curtain walls and the like, lightness and flatness are required.

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

[0006]

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, and the structural plate is a hard panel. Yes, it is divided vertically and horizontally with a phase shift in the row or column direction, and each section has a hexagonal shape and has a regular hexagonal protrusion that rises on one surface of the plate surface at the same rising height in the section. The protrusion has a flat surface on the top, the other surface is open, the intervals between the sides of the protrusion in each adjacent partition are the same, the structural plate of each layer is relatively Two or more layers are laminated such that one layer section is evenly spread over the other three sections.

Further, between the protrusions of the sections adjacent to each other,
The grooves are formed so as to communicate with each other through grooves formed in protrusions formed on the plate surface over the respective partitions.

Further, there is a pair of structural plates between the face plates, and the structural plates of each pair are joined so that the top planes of the protrusions face each other.

Further, each projection provided on the structural plate has a small hole in the top plane, and the small hole communicates the inside and outside of the projection between the layers with each other and serves as an inlet for the filler to be filled in the layer. It will be.

[0010]

The structure plate is a hard panel such as a thin steel plate or a synthetic resin plate. The protrusions in each section are formed by shaping a plate surface to stand up on one surface. Since the phases of the protrusions raised in each regular hexagonal section of the plate surface are shifted in the row or column direction, they are blocked by the protrusions against a load and are not easily deformed. The load applied from one side of the panel is distributed when the projecting parts are faced to each other and the pair of structural plates are overlapped so that each projecting part contacts the three projecting parts on the other side evenly. Then, the pressure resistance is improved. Even if the hollow sides of the protrusions face each other and the pair of structural plates are superposed, the same effect is obtained.

Between the structural plates of each layer and between the structural plate and the face plate,
Although they are bonded together by an adhesive or welding, after the bonding, if a filling material such as foam or inorganic hollow beads is filled inside and outside the protrusions of each layer through the small holes opened in each protrusion, the impact on the panel can be reduced. The resistance against compressive force is further improved.

EXAMPLE An example in which the present invention is applied to a double-floor floor panel will be described below with reference to the drawings. FIG. 1 shows an example of a double floor floor panel according to the present invention. The floor panel of the embodiment shows an example in which the structural plates 3 and 3 are interposed between the front plate 1 and the rear plate 2 in two layers.

The structural plate 3 is a thin steel plate, and the plate surface is divided into regular hexagons in a dense arrangement as shown in FIG. D for each section
Then, the section D is formed in the vertical and horizontal directions of the plate surface with the phase shifted in the row or column direction, and in the section D, a regular hexagonal protrusion 4 that rises to the plate surface at the same rising height by press working is formed. It was done. A hollow portion 5 having an opening on the other surface is formed in the protrusion 4 as shown in FIG. The sections D and D are densely arranged, and the protrusions 4, 4, ...

The top of the protrusion 4 is a flat surface, and a small hole 6 is opened at the center of the top. When stacking structural plates,
As shown in FIG. 4, the projecting sides of the plate surfaces are butted against each other,
Also, the protrusion 4a of the first-layer structure plate 3a and the second-layer structure plate 3
The protrusions 4b of b are displaced from each other, and the protrusions 4a of one layer are replaced by the three protrusions 4b, 4b of the other layer as shown in FIG.
4b so as to be evenly laid over and laminated on both sides of the structure plate 3a, 3b of both layers.
The front plate 1 and the rear plate 2 are attached to the surfaces of the hollow portions 5a and 5b on the side of b.

The face plates used for the front plate 1 and the back plate 2 are not particularly limited, and inorganic material boards, foamed concrete, wooden boards and other floor base materials can be used. As vinyl tiles,
Stick the tile carpet.

Since the structural plate 3 has the regular hexagonal protrusions 4 in each section D formed by the dense arrangement, each protrusion 4 resists the bending stress and the bending strength is large, and the protrusions 4a of one layer are formed. Since the structural plates 3a, 3b are laminated in two layers, each of which is in even contact with each other on the three protrusions 4b, 4b, 4b of the other layer, the load can be dispersed and the surface strength can be increased.

Further, in FIG. 6, each protrusion 4a of one structural plate 3a is replaced by three protrusions 4b of the other structural plate 3b.
4b, 4b, when stacked on top of each other, the small holes 6 on each of the protrusions 4a are relatively different from each other on the other structural plate 3b.
The protrusions 4b, 4 will be located in the space between the 4b, and the three sides of the laminate are sealed and the filler M such as a foam material or inorganic hollow beads is injected from one open side.
The hollow member 5 of the protrusions 4a and 4b is filled with the filler through the gap between b and the small hole 6 to form a solid-structured panel, which can further improve the resistance against impact and compression force.

7 (a) and 7 (b), a ridge 7 projecting to one side of the plate is formed on each side of each protrusion across each section D, and a groove 8 in the ridge 7 is formed. 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 become ribs to increase the strength, and the ridges 7
The filling material M can be easily filled in each protrusion 4 through the groove 8 therein.

In the floor panel, since increase in weight does not become a particular problem, it is effective to use a solid material by using a filler, but it is effective for a panel such as a curtain wall which needs to be lightweight. No material is used.

In the above embodiment, an example in which the protrusions 4a and 4b are butted against each other to combine the pair of structural plates 3a and 3b has been described. Specifications are possible. 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 protrusions are used in the compartments formed by the dense arrangement, the bending strength of each structural plate is large, and
Since two or more structural plates are laminated by straddling the protrusions of one structural plate over the three protrusions of the other structural plate, it is possible to effectively disperse the concentrated load and obtain a structural panel with high surface strength. You can
Further, a pressure-resistant filler is injected and cured in the hollow portions of the protrusions and in the gaps between the protrusions to enhance the integrity and further improve impact resistance and pressure resistance.

As the structural plate, a hard synthetic resin plate can be used in addition to the thin steel plate, but by drawing the thin steel plate, the strength can be increased and the structural panel can be made lighter. Furthermore, according to the present invention, not only a flat panel but also a structural panel can be curved and combined, and can be applied to a floor panel, a curtain wall, other interior materials, and a large diameter pipe of a container. Since it can be applied with heat insulation properties, it has the effect of being widely applicable to various types of heat insulation, heat insulation boards, structural panels such as cooling tanks.
