Abstract

PURPOSE:To shorten working hours by providing beams parallel to one another within an outer frame formed by girders, and fixing a joist and a floor panel to the upper face of each beam, and providing a sound-insulating material below the floor panel. CONSTITUTION:Beams 2 each made by O-steel are provided parallel to one another and at regular intervals inside an outer frame 1 made by girders of U-steel and both end portions of each beam 2 are fixed to the outer frame 1 via joint plates 6. A joist 3 is fixed to the upper face of each beam 2 in the direction perpendicular to the beams 2 and a floor plate 5 is laid on the joist 3. A sound-insulating material 4 made by a particle board is fixed to the side face of each beam 2 via a wood rail 7 in such a manner that the material 4 does not project from the upper face of each beam 2. The work of assembling the soundinsulating material 4 to the floor can thus be carried out in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to floor structures for buildings, particularly those having a soundproofing function.

(Prior Art) Conventionally, as a floor structure provided with a sound insulating material, for example, Japanese Patent Laid-Open No. 63-304872 and Japanese Patent Laid-Open No. 63-3
The one described in Japanese Patent No. 04873 is known.

This conventional publication describes a floor structure in which small beams are arranged in parallel within an outer frame formed by large beams, joists and sound insulating material are fixed to the upper surfaces of these small beams, and floorboards are fixed to the upper surfaces of the joists. It is shown. Note that the joists are arranged in parallel in a direction perpendicular to the small beams.

(Problem to be solved by the invention) However, in such a conventional floor structure, since the joists and the sound insulation material are fixed to the upper surface of the small beam, it is difficult to prevent the sound insulation material from interfering with the joists. In order to do this, it is necessary to divide the sound insulating material according to the spacing between the joists and install the divided members between each joist. Therefore, there was a problem in that it took a lot of time to assemble the sound insulation material.

The present invention has focused on the above-mentioned conventional problems, and an object of the present invention is to provide a floor structure in which the work of assembling sound insulating materials during construction can be carried out in a short time.

(Means for Solving the Problems) In order to solve the above problems, in the floor structure of the present invention, small beams are arranged in parallel within the outer frame formed by the large beams, and small joists are arranged on the upper surface of the small beams. In a floor structure in which a floor plate is fixed in a direction perpendicular to a beam, a floor plate is fixed to the upper surface of the joist, and a sound insulating material is provided on the underside of the floor plate, the sound insulating material is arranged between the joists from the upper surface of the joist. It is installed so that it does not protrude upward.

(Function) In the floor structure of the present invention, the sound insulating material is provided between the small beams so that it does not protrude above the upper surface of the small beams, so that the sound insulating material can be integrated into a large integrated sound insulating material while avoiding interference between the sound insulating material and the joists. can be provided between the beams.

(Example) Embodiments of the present invention will be described below based on the drawings.

First, the configuration of the embodiment will be explained.

FIG. 1 is a plan view showing the floor structure of the embodiment of the present invention, FIG. 2 is a sectional view taken along the line ■-■ in FIG. 1, and FIG.
Figure 4 is an enlarged view of the main part (■) in Figure 3. In the figure, 1 is the outer frame, 2 is the small beam, 3 is the joist, 4 is the sound insulation material, and 5 is the floorboard. .

The outer frame 1 is formed into a rectangular shape as shown in FIG. Further, the outer frame 1 consists of a girder made of mouth-shaped steel, as shown in FIG.

The small beams 2 are made of mouth-shaped steel, and a plurality of beams 2 are provided in the outer frame 1 in parallel to each other at equal intervals. Further, as shown in FIG. 2, each of the small beams 2 has both ends fixed to the outer frame 1 via a joint plate 6 by welding or the like.

The joists 3 are provided in a direction perpendicular to the small beams 2, and a plurality of joists are provided parallel to each other at equal intervals. Each joist 3 is fixed to the upper surface of the small beam 2.

The sound insulating material 4 is a large integrated piece made of particle board, and two pieces are provided between the small beams 2 so as not to protrude above the upper surface of the small beams 2.

Further, each sound insulating material 4 is fixed to the side surface of the small beam 2 via a wooden crosspiece 7.

Note that 8 and 9 in FIG. 2 are nails.

The floorboard 5 is fixed to the upper surface of the joist 3 with nails (not shown).

Next, the operation of the embodiment will be explained.

As mentioned above, the floor structure of this embodiment uses an integrated large sound insulating material 4, and this sound insulating material 4 is placed between the small joists 2 in order to avoid interference with the joists 3. It is provided so that it does not protrude above the top surface of the. That is, by providing the integrated large sound insulating material 4 between the small beams 2, the sound insulating material 4 can be assembled in a short time during construction.

Moreover, since the wooden crosspiece 7 is fixed to the side surface of the small beam 2 as a support for the sound insulating material 4, the sound insulating material 4 can be efficiently fixed by a simple operation of nailing.

Although the embodiment has been described above based on the drawings, the specific configuration is not limited to this embodiment, and even if there is a design change within the scope of the gist of the present invention, it is included in the present invention. .

For example, in the embodiment, a floor structure in which two sound insulation materials are provided is shown as an example, but the number of sound insulation materials does not need to be limited to this.

Further, in the embodiment, a sound insulating material made of particle board is shown, but the material of the sound insulating material is not limited to particle board, and may be, for example, concrete, stone, or the like.

(Effect of the invention) As explained above, in the floor structure of the present invention,
Since a large integrated sound insulating material can be provided between the small beams, it is possible to assemble the sound insulating material during construction in a short time.
