Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel and a floor structure used for buildings such as houses and apartments.

[0002]

2. Description of the Related Art In a building such as a house, as shown in FIG. 7, a floor plate 5 made of plywood, particle board or the like is used.
2 and a plurality of wooden joists 53..
In some cases, a floor panel 51 configured to be joined and integrated with is used.

However, the floor panel 51 as described above
Since the joists 53 are made of wood, their dimensions are likely to be out of order. The misalignment of the joists 53 ...
Eventually, the shape of the floor panel 51 spreads out, and when the joists 53 are warped, for example, the floor panel 51 also warps.

The joists 53 are used to give the floor panel 51 the necessary rigidity.
In general, the amount of wood used for one floor panel 51 is considerably increased, which is contrary to the idea of coexistence with the environment in which the amount of wood used is reduced as much as possible.

Further, although the use of the joists 53... Certainly increases the rigidity, there is a disadvantage that the floor panel 51 becomes heavy.

The present invention has been made in view of the above-mentioned conventional problems, and has a sufficiently high rigidity, does not cause a deviation in size and shape, and has an environmental symbiosis. It is an object of the present invention to provide a floor panel and a floor structure that match the concept and can realize further weight reduction.

[0007]

The object of the present invention is to provide a metal corrugated sheet which is superimposed on a flat lower surface of a floor plate, and the floor plate is joined to a mountain plate portion of the metal corrugated sheet to integrate the floor plate and the metal corrugated sheet. A floor panel, and a metal corrugated sheet is superimposed on a flat lower surface of the floor sheet, and the floor panel is joined to a mountain plate portion of the metal corrugated sheet to integrate the floor panel and the metal corrugated sheet. The problem is solved by a floor structure characterized by being made.

That is, the floor panel and floor structure of the present invention use a metal corrugated plate in place of a conventional wooden joist.
The metal corrugated sheet is lightweight and exhibits high rigidity among various metal structural materials, and does not cause irregularities in dimensions and shapes such as warpage as in the case of wood.
Therefore, a light-weight floor panel and floor structure with high rigidity, no deviation in size and shape, and light weight can be realized. Further, since the rigidity is increased by using a metal material, the amount of wood used is greatly reduced, and the concept of coexistence with the environment is met.

In addition, since folded plates are used as metal corrugated sheets, many of the folded plates are widely commercially available as roofing materials and the like, and are easily available. Panels and floor structures are made cost-effectively.

[0010]

Next, embodiments of the present invention will be described with reference to the drawings.

1 to 3 show a first embodiment in which the present invention is applied to a floor panel. In this floor panel 1, reference numeral 2 denotes a floor plate, reference numeral 3 denotes a metal corrugated plate, In this embodiment, the frame 4 is further used.

The floorboard 2 is formed of a square board made of plywood, particle board, or the like.

The metal corrugated plate 3 is made of a steel plate, and the top 3a of the hill, the bottom plate 3b of the valley, and the rising plate 3c are all flat, and the upper side is shorter than the lower side. It is formed into a corrugated sheet of a type in which trapezoidal ridges and inverted trapezoidal valleys whose upper side is longer than the lower side are alternately repeated.

The frame 4 is a steel frame made by joining the ends of four rectangular steel pipe members to form a square ring.

The floor panel 1 has a floor plate 2
The steel frame 4 is arranged on the lower side, and these three members are joined and integrated to be manufactured. That is, the folding plate 3 and the steel frame 4 are arranged such that the folding plate 3 is arranged on the upper surface of the steel frame 4 and between the bottom plate portions 3b of each valley of the folding plate 3 and the upper surface of the steel frame 4. The vibration isolator 5 made of rubber or the like is interposed and fastened by a fastening member 6 such as a drill screw to be integrally joined. The folding plate 3 and the floor plate 2 are arranged such that a flat lower surface of the floor plate 2 is disposed on the upper surface of the top plate portion 3a of each crest of the folding plate 3, and an adhesive 7 such as butyl tape is interposed therebetween. Then, the folded plate 3 and the floor plate 2 are bonded to each other, and are also joined and integrated by a fastening member 8 such as a tapping flathead screw. The floor panel 1 is manufactured at a factory.

By the way, as a specific example, the size of the floor plate 2 is, for example, 12 mm.
The plate 3 has a thickness of, for example, 0.5 mm and a height of, for example, 88 mm. The steel frame 4 has a thickness of, for example, 2.3 mm and a height of, for example, 100 mm.

The floor panel 1 having the above-described structure uses steel folding plates 3 in place of conventional wooden joists to ensure rigidity. Therefore, the folding plates 3 are warped to produce floor panels. There is no problem such as warping 1
It is possible to effectively solve the problem of size and shape deviation.

Moreover, the folded plate 3 can exhibit high rigidity while being light in weight as compared with a metal member having another structure. The rigidity can be increased, and at the same time, the floor panel 1
Can be reduced in weight while having a metal structure portion. Therefore, it is not impossible to realize a floor panel having the same rigidity as the floor panel using the wooden joist, but being lighter than the floor panel using the wooden joist.

Furthermore, since the conventional wooden joists are eliminated and the wooden portion is reduced, it is possible to realize an environment-friendly floor structure that is compatible with the concept of coexistence with the environment.

The floor panel 1 can be manufactured in a cost-effective manner by using a steel plate 3 widely used as a roof material or the like.

Furthermore, in the present invention, a metal corrugated sheet having repeated peaks and valleys, such as a folded plate, is used as a reinforcing material for securing the rigidity of the panel 1.
As compared with the floor panel 1 having a structure in which a plurality of joists 53 are arranged in parallel at predetermined intervals on the lower surface of the floor panel 2 and the like, the attachment of the reinforcing material to the floor panel becomes much easier,
The floor panel 1 can be manufactured with high productivity.

The floor panel 1 of the second embodiment shown in FIG.
It is composed of a floor plate 2 and a folded plate 3, and a steel frame is omitted. Urethane foam 10 as a heat insulating material is injected into each of the plurality of chambers 9 in the width direction surrounded by the floor plate 2 and the folding plate 3, thereby improving the heat insulating property, strength, and vibration isolation of the panel 1. It has been made. Others
This is the same as the above embodiment.

The floor panel 1 of the third embodiment shown in FIG.
The floor plate 2 is composed of a floor plate 2, a folded plate 3, and a bottom plate 11 made of plywood or the like, and the bottom plate 11 is also joined and integrated with the bottom plate portion 3b of the valley of the folded plate 3 in the same manner as the floor plate 2. is there. Urethane foam 10 as a heat insulating material is injected not only into each chamber 9 surrounded by the floor plate 2 and the folded plate 3 but also into each chamber 12 surrounded by the bottom plate 11 and the folded plate 3. In addition, the heat insulating property, strength, and vibration damping property of the panel 1 are further enhanced.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention. For example, the floor material 2 is not limited to plywood or particle board, and other various floor materials may be used. Further, in the above embodiment, one folding plate 3 is overlapped on the lower surface of one floor plate 2 and these are joined and integrated to form one floor panel 1.
Is shown, but a plurality of floorboards are taken as one unit,
It is also possible to adopt a structure in which one folding plate is stacked so as to pass over the lower surfaces thereof, and a plurality of floor plates and one folding plate are joined and integrated to form one panel. In addition, in the above embodiment, a steel folding plate 3 widely used as a roof material is used as a metal corrugated sheet. However, in order to emphasize the uniqueness of the floor panel, a specific size and shape are used. Folding by a designed exclusive product may be used. In addition to the folding plate 3 having the shape shown in the figure, folding plates having various cross-sectional shapes as shown in FIGS. 6 (b) and 6 (c) may be used.
A metal plate may be formed by bending a metal plate by a press or the like, or may be formed by a shaped material or the like. The material may be made of various other metal materials such as aluminum, in addition to the material made of iron-based metal. Also,
