Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of earthquake-resistant walls and beams in a building.

[0002]

2. Description of the Related Art In a building, it is necessary to integrate upper and lower beams and left and right columns in order to ensure that the earthquake-resistant wall functions properly. Therefore, in the case of a cast-in-place reinforced concrete earthquake-resistant wall, in construction, the earthquake-resistant wall and the beam are simultaneously framed in the vertical direction, and the concrete is simultaneously cast to integrate them.

[0003]

However, in this case, the formwork work on the site becomes very complicated, and there is a problem in terms of workability and work time in recent years when there is a shortage of skilled workers. It is an object of the present invention to provide a construction structure for earthquake-resistant walls and beams in a building that can solve such conventional problems.

[0004]

In order to achieve the above object, in the present invention, in a structure of a reinforced concrete earthquake-resistant wall and a beam arranged above and below it, a pair of U-shaped cross-section steel aggregate members are arranged at predetermined intervals. Arranged in a tying manner so that the flanges face each other by defining a gap portion, the pair of steel aggregates is used as a beam form, and the seismic wall formwork is formed on the basis of the beam form, A vertical bar of the earthquake-resistant wall is extended through the gap between the pair of steel aggregates to arrange the bar, and the earthquake-resistant wall and the concrete of the beam are simultaneously struck to improve workability and seismic resistance. It is characterized by ensuring the structural integration of walls and beams.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention.
Is a longitudinal sectional view of an essential part showing an outline of a construction structure of an earthquake-resistant wall and a beam according to the present invention, and FIG. 2 is a sectional view of an essential part after the construction.

In this embodiment, when arranging and framing the earthquake-resistant wall and the beam on a certain floor, the beam 1 is firstly formed, and then the earthquake-resistant wall 2 is formed on the basis of this. There is. That is, in the beam 1, first, a pair of U-shaped cross-section steel aggregates 3, 3 are formed at a predetermined position by so-called tying so that the flanges 3a face each other with a gap 4 at a predetermined interval defined. Arranged and fixed, the pair of steel aggregates 3,
3 is used as a beam form. After that, the work of assembling the form 5 of the earthquake resistant wall 2 is performed with the steel frame 3 as the beam form as a reference, and the vertical stripes 6 of the earthquake resistant wall 2 are also assembled.
Is pierced through the gap portion 4 between the pair of steel aggregates 3 and 3, and is reinforced.

In this way, the seismic wall 2 and the concrete 7 of the beam 1 are simultaneously placed after the reinforcement work and the formwork work are completed, and after the formwork is disassembled, the beam 1 is made as shown in FIG. The pair of steel aggregates 3 is filled with concrete 7 and the vertical bars 6 pass through. The upper part of the vertical bars 6 extending from the upper surface of the beam 1 is used for fixing the upper floor wall. It will be in the state of being projected.

In order to integrate the steel aggregate 3 of the beam 1 with the concrete 7 to be cast, a shear connector 8 such as a stud is fixed in advance as shown in the figure.

In this embodiment having such a structure,
Since the beam form made of a pair of steel frame members 3 is fixed at a predetermined position in advance, the form 5 of the earthquake-resistant wall 2 can be assembled using the beam form as a gauge, and the workability is remarkably improved, and the work time is shortened. The formwork work can be completed with. Also,
Since the beam formwork is fixed to the correct position in advance, the construction accuracy is high and the quality can be improved. Further, since the beam 1 does not require a conventional formwork, complicated formwork work can be omitted, which is rational. Furthermore, since the beam 1 and the earthquake-resistant wall 2 are simultaneously constructed, the concrete 7 of both is integrated and has high rigidity, and the function as the earthquake-resistant wall 2 can be reliably exhibited. Further, since the beam 1 uses the vertical streaks 6 of the earthquake-resistant wall 2 as it is, the beam 1 is easily assembled.

It is needless to say that the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.

[0011]

The present invention is constructed as described above,
The following effects can be achieved. (1) Since the beam form made of a pair of steel frames is fixed in advance at a predetermined position, the form of the earthquake-resistant wall can be assembled using the beam form as a gauge, and the workability is remarkably improved, and the work time is shortened. The formwork work can be completed with. (2) Since the beam formwork is fixed to the correct position in advance, the construction accuracy is high and the quality can be improved. (3) Since the beam formwork as in the conventional case is not necessary, complicated formwork work can be omitted, which is rational. (4) Since the beam and the earthquake-resistant wall are simultaneously constructed, the concrete can be integrated and the rigidity can be increased. (5) Since the beams use the vertical streaks of the earthquake-resistant wall as they are, they are easy to assemble.
