Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a floor structure using a composite floor panel capable of forming a floor excellent in sound insulation effect and having excellent strength.

[Conventional technology]

Conventional sound insulation floors usually have soft fiberboard between double plywood,
There is a short tubular paper tube made into a honeycomb shape, or a glass fiber sandwiched in a sandwich shape.
Pass the joists between the double plywood, and in this space rock wool,
Some were filled with antiseptic sawdust.

[Problems to be solved by the invention]

However, flooring materials used in conventional sound insulation floors do not have enough strength to withstand floor loads themselves, and therefore require joists, and depending on the floor structure, there is no way to interpose joists between plywood. Did not get. Furthermore, when laying floor materials, it is necessary to consider the directionality of the floor materials, and the construction efficiency is not always good.

An object of the present invention is to provide a floor structure using a composite floor panel which has a high construction efficiency without requiring the directionality, and has a strength which does not require a joist or the like.

[Means for Solving the Problems] The present invention provides a first plywood that forms a floor surface, a second plywood that is thicker than the first plywood and has a thickness of 12 mm or more and has floor load resistance, A composite floor panel formed by integrating an intermediate material formed of an inorganic material having a shape-retaining property and a sound-insulating property with being sandwiched therebetween is fixed by placing its end on a floor beam, The above object has been attained by providing a floor structure using a composite floor panel characterized by laying a finishing material on the floor.

[Action]

According to the floor structure using the composite floor panel of the present invention, a part of the composite floor panel is cut off in accordance with the shape of the floor surface to be laid, and the panel is fixed on a floor beam and fixed. A floor structure can be formed simply by laying a finishing material on the panel, and the floor structure can withstand a load and have sound insulation without a joist.

〔Example〕

The present invention will be described below based on the embodiment shown in FIGS. In each of the drawings, FIG. 1 is a partial sectional view showing an embodiment of a composite floor panel constituting the floor structure of the present invention, and FIG.
FIG. 1 is a cross-sectional view showing one embodiment of the floor structure of the present invention, in which the sash portion is attached to the composite floor panel shown in FIG.

The composite floor panel 10 constituting the floor structure of the present embodiment is the first type.
As shown in the figure, a first plywood 11 which forms a floor surface, a second plywood 12 which is thicker than the first plywood 11 and has a floor load resistance, and which are sandwiched by these two plywoods 11 and 12 to maintain shape retention and sound insulation It is formed by integrating an intermediate material 13 having properties.

The first plywood 11 and the second plywood 12 are both formed of conventionally known plywood, and each of the plywoods 11 and 12 has no directivity itself.

The intermediate material 13 has shape retention and sound insulation as described above, and includes, for example, inorganic materials such as gypsum, calcium silicate, and fly ash. Each of these materials can be given a certain form by molding, and has excellent sound insulation.

The second plywood 12 is thicker than the first plywood 11 and has a higher tensile strength, and is used as a floor material of a structural floor.
Even when a load is applied to the composite floor panel 10, the amount of deflection of the floor falls within an allowable value (1/300 of the span).

Since the composite floor panel 10 constituting the floor structure of the present embodiment has the above-described configuration, the composite floor panel 10 can be manufactured to a fixed size in a factory, and the manufactured composite floor panel 10 itself has an amount of deflection with respect to a predetermined floor load. Is within the range of the allowable value, and it is possible to form a structural floor having sufficient strength even without a joist simply by hanging between floor beams and fixing to the floor beams with screws or the like. Moreover, if the installation interval of the receiving material supporting the composite floor panel 10 is equal to or less than the width of the composite floor panel 10, the installation can be performed without considering the directionality thereof, so that the construction efficiency is remarkably improved. Also, this composite floor panel
In the case of laying, the composite floor panel 10 can be laid by simply cutting out necessary portions such as portions corresponding to pillars and placing it on the floor beam 20, and is excellent in workability.

When laying the composite floor panel 10, as shown in FIG. 2, one end of the composite floor panel 10 is placed on the floor beam 20, and one end of the composite floor panel 10 is fixed to the floor beam 20 with screws (not shown). Next, a packing material 40 is interposed between the aluminum sash 30 and the composite floor panel 10, and further, the composite floor panel 10 and the packing material
The floor can be finished by laying a floor finish 50 on top of 40. In addition, as this composite floor panel 10,
For example, a plywood having a size of 900 mm × 1800 mm and a thickness of the first plywood 11 of 5.5 mm, a plywood of the second plywood 12 of 12 mm and an intermediate material 13
Is composed of 12mm plaster.

The composite floor panel constituting the floor structure of the present invention includes a first plywood that forms a floor surface, a second plywood that is thicker than the first plywood and has a floor load resistance, and is sandwiched and formed by these plywoods. The material of each plywood and the intermediate material are not particularly limited as long as they are formed by integrating an intermediate material having a retaining property and a sound insulating property.

[Effect of the invention]

Since the composite floor panel constituting the floor structure of the present invention does not need to take into account the directionality, the floor structure of the present invention is formed with high construction efficiency. In addition, the composite floor panel is hung between floor beams, fixed to the floor beams with screws or the like, and a finishing material is laid on the composite floor panel. A floor structure having improved sound insulation can be formed.
