Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete floor construction method of a frame wall construction method, in which an upper floor is constructed with concrete when a general house or the like having a plurality of floors is constructed by the frame wall construction method.

[0002]

2. Description of the Related Art Conventionally, a multi-storey general house constructed using a framed wall construction method has a good insulation of sound inside and outside because it is constructed of a wall structure with high heat insulation and airtightness. Sound vibration was transmitted in the vertical direction, and it was not desirable to block the sound from the upper and lower floors. In particular, in the case of apartment buildings in recent years, it is strongly desired to block sound from the upper and lower floors, and it is expected that the standard for sound blockage will become even higher due to the revision of the Building Standards Law. Under these circumstances, in recent years, it has been required to construct the upper floor by concrete construction instead of wooden construction so as to enhance the sound insulation of the upper and lower floors. Conventionally, in such a concrete floor construction method of the frame wall construction method, first, after erecting the lower floor, concrete placement is performed on the floor surface part of the upper surface to raise the upper floor, and this upper floor I was trying to raise the upper floor on the floor. For houses on the 3rd floor and above,
After erecting the upper floor wall in this way, the uppermost floor and the uppermost floor were constructed by the same procedure.

[0003]

However, in the conventional concrete floor construction method of such a framed wall construction method, after the wall of the lower floor is built up, the erection work is temporarily stopped, and the upper surface of the lower floor wall is suspended. Concrete construction work such as foundation bar arrangement and concrete placement is performed on the section to build the upper floor, and then erection work is started again to erected the upper floor wall. Since different types of work were alternately performed, there was a problem that the efficiency of erection work was very poor. For houses on the 3rd floor and above,
Waiting for the concrete placed on the upper floor to dry before erection of the upper floor wall, and waiting for the concrete placed on the uppermost floor to wait for the concrete to dry up, erection of the top floor. Since there were crossings, there was a problem that the entire construction period would be extremely long.

[0004]

12b and. Further, each linking member 12b is formed with a notch corresponding to the linking member 11b, and the lower member 11 and the upper member 12 can be linked through the notch. Then, the upper floor wall 3 is placed on the upper member 12 of the support fitting 10, and the upper member 12 is fastened to the upper floor wall 3 by using a nail to raise the upper floor wall 3.

Further, each of the above-mentioned supporting fittings 10 is attached to the height adjusting mechanism 1
FIG. 11 shows a case of being configured as having 0a.
Will be explained. That is, the lower member 1 of each support fitting 10
1, a round bar 11c is provided in a projecting shape substantially at the center of the upper surface of a bottom member 11a. A thread portion is formed on the upper portion of this round bar 11c, and a nut is fastened and fixed to this thread portion. Has been done. Further, the upper member 12 linked to the lower member 11 is configured by providing a short cylinder 12c in a protruding shape at a substantially lower surface of a wall receiving member 12a. These lower members 11
The upper member 12 and the upper member 12 can be freely linked by inserting the round rod 11c into the short cylinder 12c and adjusting the fastening position of the nut. Then, the upper floor wall 3 is placed on the upper member 12 of the support fitting 10, and the upper member 12 is fastened to the upper floor wall 3 by using a nail to raise the upper floor wall 3.

Next, FIG. 12 shows a case where the above-mentioned respective support fittings 10 are integrated and the above-mentioned bar arrangement unit 9 can be divided.
Will be explained. In this case, after fixing each supporting metal fitting 10 integrally formed on the base plate 6, the rebar unit 9 divided in advance to an appropriate length is sandwiched by the fixed supporting metal fitting 10 from both sides. Thus, the connecting portion 9a is fastened by welding or the like. Then, the upper floor wall 3 is placed on the upper portion of the support metal fitting 10, and the support metal fitting 10 is fastened to the upper floor wall 3 by using a nail to raise the upper floor wall 3.

The raising of the upper floor wall 3 will be described. The upper floor wall 3 is placed on the upper surfaces of the plurality of support fittings 10 and, as shown in FIG. 9, the plurality of connecting bolts that penetrate the upper floor wall 3 and the lower floor wall 2 through the reinforcing bar unit 9. Tighten at 13, 13. That is, the upper floor 3 is placed on the upper surface of the wall receiving member 12a of the upper member 12 of the support fitting 10 and is fastened to the support fitting 10 by a nail penetrating the side wall of the wall receiving member 12a. As shown in FIG. 5, the plurality of panel plates constituting the upper floor wall 3 are formed by arranging a plurality of vertical members in parallel inside the rectangular frame and stretching plate members on both side surfaces thereof. Before the plate material is stretched or in a state where it is stretched on one side surface, the above-described raising and lowering is performed, and after the connection bolt 13 is fastened, another plate material is stretched.

The placing of the concrete 4 will be described. Concrete 4 is poured into the wall arranging portion 16 as shown in FIG. 7. This concrete pouring is performed by pumping the concrete 4 to the upper part of the balcony portion 7 protruding to the outside and other places. The concrete 4 is cast at substantially the same height as the wall arrangement portion 16, and the floor surface portion 1
5 covers almost the entire surface.

[0024]

As described above, in the concrete floor construction method of the frame wall construction method of the present invention, the lower floor is raised and the base plate is stretched on the floor surface portion of the upper floor, and the reinforcing bar unit is mounted on the base plate. After installing the support metal fittings and erected the upper floor wall on the upper surface of the support metal fittings, concrete placement is performed, so that after the erection work on the lower floor wall, etc., this can be continued without interruption. Since erection work such as walls can be performed and concrete construction work is performed after completion of these erection work, there is an effect that the erection work can be performed very efficiently. In particular, after constructing the roof after constructing the upper floor wall, slab reinforcing bars are laid on the base plate surrounded by the reinforcing bar unit, and concrete is placed on the floor surface. The concrete can be placed after the building including the roof is completely finished, and the erection work can be performed very efficiently. Further, since the roof construction is completed before the slab reinforcement and the concrete are laid, these concrete laying can be performed even in rainy weather and the work is further speeded up.

Further, according to the present invention, after the upper floor wall is erected, the uppermost floor wall is further erected on the upper floor wall by the same procedure as the upper floor wall, and the slab reinforcing bars are arranged on the base plate of each floor. In this case, concrete can be placed on each floor after the floors have been erected, and the drying period of the concrete does not extend again. Therefore, there is an effect that the entire implementation period can be shortened.
