DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a floor structure of a dwelling unit according to the present invention will be described with reference to FIGS. FIG. 1 shows an overall view of a dwelling unit according to the present invention, in which reference numeral 1 denotes a dwelling unit.

The dwelling unit 1 includes four pillars 2 and a ceiling beam 3 connecting the upper ends of the pillars 2 in a frame shape.
And a frame formed in a rectangular parallelepiped box shape by floor beams 4 connecting the lower ends of the pillars 2 in a frame shape, and a wall body 5 forming an outer wall of the dwelling unit 1.
The interior of the frame is a living space A.

The column 2 is formed of L-angle steel material and mainly resists vertical force (vertical load). The inner corner side is disposed toward the living space A, and the outer corner side is formed. It is disposed so as to substantially coincide with the corner of the dwelling unit 1. The ceiling beam 3 and the floor beam 4 are attached in a frame shape by a plurality of steel channel members. A ceiling surface and a floor surface are formed in a portion surrounded by these channel materials.

That is, as shown in FIG. 2, the channel members 3 and 4 constituting the ceiling beam and the floor beam are webs 3a and 4
a at the upper and lower ends of the webs 3a, 4a.
The flanges 3b, 3c, 4b, and 4c are provided so as to extend horizontally to the channel material side opposed to each other, and both ends 3e are provided by welding to the widthwise edge of the column 2. ing. The ceiling channel material 3 and the floor channel material 4 extending in the longitudinal direction of the dwelling unit 1 are divided and supported by an intermediate column 6 having a T-shaped horizontal cross section extending in the same direction as the column 2.

The wall 5 is disposed between the column 2, the ceiling channel 3, the floor channel 4, and the intermediate column 6. The wall 5 is made of a steel plate having a sufficient strength. The vertical edge is joined to the width edge of the column 2 by welding or the like, and the horizontal edge is a ceiling channel material. 3 and the upper part of the floor channel material 4 are joined and arranged. And on the inner surface side of this wall body 5,
Middle beams 7 having an L-shaped cross section are provided at predetermined intervals in parallel with the ceiling channel material 3 and the floor channel material 4.

Here, as shown in FIG. 3, the floor channel member 4 has a lower flange 4c having a side end protruding further in a direction of forming a floor surface than a side end of the upper flange 4b.
To so that is formed.

As shown in FIGS. 2 and 3, the floor channel member 4 arranged in a frame shape between the lower ends of the pillars 2 has an ALC plate having excellent sound insulation and heat insulation. lightweight
Aerated concrete version) 8 of the floor channel material 4 web
4a .

The ALC plate 8 includes a plurality of floor channel materials.
4 is formed in substantially the same quadrangular shape as the frame constituted by the floor channel material 4 as shown in FIG.
On the lower flange 4c.

The edge 8a and the lower flange 4c of the ALC plate 8 are fixed over the entire lower surface of the dwelling unit 1 by being fixed by driving a fixing member 9 such as a screw nail from above. Form the floor.

In this embodiment, an inner wall of a gypsum board or the like for improving fire resistance and sound insulation is provided on the inner wall side of the wall 5.
Coating plate 10 is stuck. This inner wall covering plate 10
Are joined by an adhesive or the like in a state of being in surface contact with the lower flange 3c of the ceiling channel member 3, the upper flange 4b of the floor channel member 4, and the tip of the center beam 7. Here, the inner wall covering plate 10 is attached with the lower end face concealing the head of the screw nail 9a driven into the ALC plate 8.

Further, a cover plate 11 on the outer wall side of the wall body 5 which is improved in fire resistance and sound insulation in a state of being in surface contact with the wall body 5.
Is affixed. In addition, the code | symbol 15 in FIG. 3 is the dwelling unit arranged just under the dwelling unit,
Reference numeral 16 denotes a connection fitting provided between the dwelling units.

Next, a procedure for forming the dwelling unit having the above configuration will be described below. First, the ceiling channel material 3 and the floor channel material 4 are attached in a frame shape between the upper end portion and the lower end portion of the four L-angle columns 2 to form a rectangular frame. At this time, channel materials 3, 4
Webs 3a, 4a are oriented vertically and webs 3a,
Flanges 3b, 3c, 4b, 4 extending from both ends of 4a
c is disposed so as to extend to the channel material side that is disposed opposite. Here, the ceiling channel material 3 extending in the longitudinal direction
The floor channel member 4 is divided and supported by the intermediate pillar 6. In addition, the floor channel material 4 is
The one formed so that the side end of c protrudes further in the floor surface forming direction than the side end of the upper flange 4b.

Next, a wall 5 is disposed between the pillar 2, the ceiling channel 3, the floor channel 4, and the intermediate pillar 6. next,
4c on the lower flange of floor channel material 4 arranged in a frame shape
Then, the peripheral portion 8a of the ALC plate 8 formed in a square shape is placed thereon. Then, screw the screw nail 9 from above the ALC plate 8 into A
A floor is formed between the floor channel members 4 by driving and fixing the peripheral portion 8a of the LC plate 8 and the lower flange 4c.

Next, the inner wall coating plate 1
0, and the covering plate 1 is also provided on the outer wall side of the wall 5.
By sticking 1, the dwelling unit is formed.
At this time, the lower part of the inner wall covering plate 10 is
Attached to the inner peripheral surface, and the inner wall covering plate 1
The lower end of 0 is in contact with the upper surface of ALC plate 8.
You.

As can be easily understood from the above description, the floor structure of the dwelling unit according to this embodiment has the ALC version 8
Disposed over the entire surface on the floor forming surface between floor channel member 4 Rutotomoni, the inner wall covering plate 10 on the upper surface of the ALC plate 8
Since the lower ends are in contact, the sound insulation performance and the fire prevention performance with the lower floor can be improved. Therefore, it is possible to provide a structure in which the heat insulation performance and fire prevention performance of the dwelling unit are enhanced. Further, unlike the conventional floor structure, a plurality of joists are bridged between the floor beams, and a wooden floor surface material is not laid on the joists to form a floor surface. By merely placing the edge on the lower flange 4c and fixing it with the screw nail 9, the floor surface is formed over the entire space between the floor channel members 4 , thereby greatly reducing labor on site. Can be.
