DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a method for constructing a building floor according to the present invention will be described with reference to the drawings.

The floor A of the house constructed in the embodiment of the present invention is employed in a wooden frame construction method called a conventional construction method, and furthermore, the floor construction on the first floor, the second floor or more floors is carried out. For example, in the case of a floor A for the first floor, as shown in FIG. 1, a plurality of pillars are arranged at predetermined intervals on a horizontal member 2 such as a base placed on a foundation 1 made of concrete or the like. And the like, and the pillars 3 are connected by a girder, a beam, and a trunk (not shown) to form a frame b. The second floor body 5 is stretched and the floor body A is constructed.

The first and second floor plates 4 and 5
Is formed in a square shape of a flat plate according to a predetermined shape that can be placed on the base 2 in the frame b, and a single plate or a plywood having a thickness of 7.5 to 30 mm is used, and the size is arbitrary. It is possible to select the size and shape of the
900 x 2400 mm, 1200 x 1800 mm, 1800 x 36
Molded like 50mm.

The first and second floor plates 4 and 5
As shown in FIGS. 3 and 4, a notch 6 to be fitted into the vertical member 3 such as a pillar or the like framed is provided at an appropriate position. According to the position, as shown in FIGS. 4 (a) and 4 (b), one or more corners and intermediate portions of the outer edge of the floor plate 4 are cut into a vertical triangular shape and recessed. Alternatively, as shown in FIG. 4 (c), a vertical member is cut into a triangular shape at an appropriate position in the middle of the floor plate 4 and a hole is formed.

In constructing the floor A, first, a frame b serving as a frame of the building is formed. As described above, the frame b is made of concrete or the like as shown in FIG. A plurality of columns 3 are erected at predetermined intervals on a base 2 placed on a foundation 1 according to the above.

As shown in FIG. 5 (a), on the first floor, the first floor plate 4 is first supported on the base 2 by arranging it.
The first floor plate 4 is previously fitted at a desired position based on the design of the building at the factory, that is, by inserting notches 6 precut at the side edges or intermediate portions of the first floor plates 4 into the pillars 3 to be brought into contact with the first floor plate 4 and nails or screws. When the base 2 is fixed to the base 2 by being fixed to the base 2 with a fixing member 7 such as nail or screw, a base portion of the floor A is formed.

Next, the joints 8 at the butting portions of the first floor plates 4, 4.
(b) As shown in (b), the joints 9 of the second floor boards 5 and 5 to be stretched are provided so as not to coincide with each other, and the second floor board 5 corresponds to the center of the joints 8. However, it is sufficient if the joint 8 and the joint 9 of the second floor plate 5 do not come close to each other.

At the position of the frame 3 located at the column 3, similarly to the first floor plate 4, the notch 6 precut at the side edge or the intermediate portion thereof is brought into contact with the second floor plate 5. 3 and is fixed to the base 2 together with the first floor 4 by a fastening member 10 such as a nail, screw nail, screw, etc., and the floor A is formed.

An adhesive 11 is provided between the floors 4 and 5.
The adhesive 11 is applied on site, or the adhesive 11 with a release paper is provided at the time of cutting the floors 4 and 5, and the release paper is peeled at the time of overlapping. Thus, the two and the four are joined.

The joint A of the first floor plates 4, 4 attached to the base 2 has a joint 8 on the upper surface of the second floor plate, even if the frame is shaken and the floor swings. 5,5
Because it is held down by ..., it does not cause misalignment or slanting when lifted.

Further, even if an abnormal gap or the like occurs in the joints 8 of the first floor plates 4, 4, the portions are covered by the second floor plates 5, 5 stretched over the joints. There is no adverse effect on the A side.

The first and second floor plates 4 and 5 are
On the outer side of the horizontal member 2, the outer edge of the horizontal member 2 and the outer edges of the first and second floor plates 4, 5 are placed so as to coincide with each other (there may be no coincidence), and the horizontal member 2 is placed on this. Metal fittings (not shown) linked to the first and second floor plates 4 and 5
The floor body A is provided with high precision horizontality by stretching the first and second floor plates 4 and 5, and furthermore has a bearing floor having a predetermined strength. A is formed.

Further, in the stretching work, the first floor plate 4 attached first serves as a work scaffold, so that the work can be safely performed.

[0025]

According to the present invention constituted as described above, the first and second floor boards are fitted on the framed horizontal member,
Because each notch is engaged with the vertical member,
Due to the lateral external force due to an earthquake or the like, there is no inconvenience such that the floorboards are displaced obliquely or the intervals between the floorboards are widened, so that a bearing floor with sufficient earthquake resistance is constructed.

Further, since a sufficient strength can be obtained as described above, the completed floor does not become distorted due to its weight or generate abnormal noise even when walking.

Further, since it is easily formed by a simple operation of placing two layers of floor boards on a framed horizontal member, the construction period can be greatly reduced and the cost can be reduced. Construction becomes possible.

At the time of construction, the first floor plate is stretched in advance on the framework to form a floor body serving as a base, so that the floor can be freely moved on the floor plate during walking or the like, so that safe construction can be performed. And so on.
