Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete floor structure 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 recent years, it has become more strongly desired to block the sound of the upper and lower floors of apartments. 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 structure of the frame wall construction method, the upper floor is erected on the upper surface of the upper floor which is constructed by placing concrete on the upper surface of the lower floor. In addition, in the case of a house with three or more floors, after erection of 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 structure of such a framed wall construction method, the erection work is temporarily stopped after the wall of the lower floor is erected, and the upper surface portion of the lower floor wall is temporarily suspended. Concrete construction work such as foundation bar arrangement and concrete placement is performed on the upper floor to build the upper floor, and then erection work is started again to erected the upper floor, which is called erection work and concrete construction work. Since different kinds of work were performed alternately, 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]

SUMMARY OF THE INVENTION In order to solve such a conventional problem, the present invention has a structure in which a lower floor wall is erected to form a lower layer, and a base is mounted on a floor portion on an upper surface of the lower floor. A plate is stretched, and a reinforcing bar unit is arranged in the wall arrangement portion where the lower floor is arranged among the floor surface parts, and a plurality of supporting metal fittings are arranged in association with the reinforcing bar unit. The upper floor wall is erected and placed on the upper surface of the, and the upper floor wall and the lower floor wall are fastened with a plurality of bolts that penetrate the reinforcing bar unit, and then the upper floor wall and the lower floor wall are joined. Concrete is cast in the wall arrangement portion between the floor wall and each of the support fittings is composed of an upper member and a lower member and is separable, and the lower member is composed of a bottom member and a linking member. , The upper member is composed of a wall receiving member and a linking member, and the lower member is placed above the bottom member via The base member is fastened to the base member, the bottom member is linked to the inside, and the reinforcing bar unit is arranged. The lower member and the upper member are linked to each other via the linking members so as to hold the reinforcing bar unit. The upper surface of the support metal fitting is flush with the upper surface of the reinforcing bar unit, and the upper member is fastened to the upper floor wall via the wall receiving member to form the upper floor wall and the lower floor wall. Are connected via respective support fittings.

Next, a method of constructing a floor according to the present invention will be described. First, as shown in FIG. 8, the lower floor 2 is erected around an arbitrary foundation floor 1 by a frame wall construction method, and a temporary beam 5 as a floor support member is provided on the upper surface of the lower floor 2 above. Install multiple. This hypothetical beam 5 is the beam body 5
It is composed of a and a mounting portion 5b, and the mounting portion 5b is attached by abutting on the notch portion 2a formed on the upper edge of the lower floor wall 2. Alternatively, as shown in FIG. 12, the hypothetical beam 5 may be attached such that the mounting portion 5b is in contact with the projecting side of the beam receiving member 17 mounted on the upper end of the lower floor wall 2.

After mounting the temporary beam 5 as shown in FIG.
As shown in 0, the base plate 6 is provided on the upper surface of the temporary beam 5.
And the lower member 11 of each of the support fittings 10 and the reinforcing bar unit 9 are arranged on the wall arrangement portion 16. Next, the upper member of each support fitting 10 is installed in association with the reinforcing bar unit 9, and as shown in FIG. 11, the upper floor wall 3 is erected and placed on the upper part of these support fittings 10. The connecting bolt 1 is formed by passing the wall 3 and the lower floor wall 2 through the reinforcing bar unit 9.
Tighten at 3.

After the upper floor wall 3 has been erected, the slab reinforcement 14 is placed on the base plate 6 surrounded by the reinforcement unit 9.
Are laid out and concrete is placed on the floor portion 16. Alternatively, after the upper floor wall 3 has been erected, as shown in FIG. 1, the roof body 20 is constructed on the upper floor wall 3, and then the slab reinforcement 14 is laid. Good. In addition, in a building with three or more floors, after the upper floor wall 3 is erected, the uppermost floor wall 2 is further provided above the upper floor wall 3.
1 is installed by the same procedure as the upper floor wall 3, the roof body 20 is constructed on the uppermost wall 21 and then the slab reinforcement 14 is arranged on the base plate 6 on each floor. You may do it. After the concrete 4 is placed on the floor surface of each upper floor in this way, the concrete 4 is dried, and the temporary beam 5 is removed from the lower floor side to complete the floor construction.

[0017]

As described above, in the concrete floor construction structure of the frame wall construction method of the present invention, the base plate is stretched on the floor surface portion of the upper surface of the lower floor, and the reinforcing bar unit and the support metal fitting are arranged in the wall arrangement portion. Since the upper floor wall is erected and the upper floor wall is erected on the upper surface of the supporting metal fittings, concrete is cast, so that the upper floor wall can be erected through the supporting metal fittings after the lower floor wall is erected. Since the concrete construction work can be performed after the erection work on the lower and upper floors is continuously performed, there is an effect that the erection work can be performed very efficiently.

In particular, each support fitting is composed of an upper member and a lower member so as to be separable, and the lower member and the upper member are arranged so that the lower member is linked to the inside to dispose the reinforcing bar unit. Since the lower member and the reinforcing bar unit are arranged and the upper member is linked to each other, the reinforcing bar unit can be held by the supporting metal fittings so as to be integrated with each other. It is possible to easily obtain a strong linkage structure of, and improve workability and robustness.

Further, according to the present invention, when each support fitting is provided with a height adjusting mechanism and the height adjusting mechanism is used to adjust the support fitting to an arbitrary height, the height adjusting mechanism allows the base plate to be adjusted. There is an effect that the height error of the support bracket itself can be adjusted, and the upper surfaces of the support brackets can be easily flush with each other.
