2. Description of the Related Art In a conventional earthquake-resistant wall, the main reinforcement of the wall is fixed to a column or a beam member, and the wall and the column or the beam are usually integrated with concrete. When this earthquake-resistant wall is formed by cast-in-place, the construction period on site becomes long, and therefore, a precast earthquake-resistant wall is often used.

[0003] This precast earthquake-resistant wall is manufactured as a precast member in which the upper and side portions are integrated with a beam member or a column member, or is integrated with a column or beam by partial cast-in-place of concrete, and It was usual to join the beam to the beam by a wet joining method using grout or the like using a sleeve or the like. In this case, the joint between the wall and the column or the beam is not precast, but the main reinforcement of the wall and the difference bar fixed to the beam or the column are joined by welding, and the periphery of this joint is surrounded by a formwork and concrete Was integrated into the wall and the pillar or beam.

[0004]

However, in the conventional precast earthquake-resistant wall, the reinforcing steel of the earthquake-resistant wall and the reinforcing steel fixed to the column or the beam had to be fixed by welding. There was a problem of increasing. Also,
Since the rigidity of the earthquake-resistant wall was set to be relatively large, the rigidity was sometimes too high compared to the rigidity of a portion having an opening such as a door or a window. In this case, columns and beams must be reinforced in order to balance the rigidity of the entire building, so that there is a problem that the number of construction steps increases.

An object of the present invention is to solve such a problem, and to provide a mounting structure for an earthquake-resistant wall capable of reducing the number of construction steps.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a structure for mounting an earthquake-resistant wall, and is configured as follows to solve the above-mentioned technical problem. That is, the mounting structure of the earthquake-resistant wall of the present invention is configured such that the first plate material is fixed to the reinforcing steel of the precast earthquake-resistant wall, and the second plate material is fixed to the column or beam member fixing the earthquake-resistant wall. It is characterized in that the first plate and the second plate are fixed.

[0007] In the mounting structure of the earthquake-resistant wall, the earthquake-resistant wall and the column or the beam can be joined by fixing the first plate of the earthquake-resistant wall and the second plate of the column or the beam. By dividing the earthquake-resistant wall into a plurality of blocks and adjusting the rigidity, the rigidity of the earthquake-resistant wall and parts other than the earthquake-resistant wall can be harmonized. In this case, the rigidity of the earthquake-resistant wall and the other parts can be balanced.

FIG. The mounting structure 1 of this earthquake-resistant wall is
Numeral 0 is arranged in a space formed by left and right pillars 11 and 11 and upper and lower beams 12 and 12. The earthquake-resistant wall 10 is precast, and the reinforcing bars 13 are arranged vertically and horizontally, and the reinforcing bars, in this example, the reinforcing bars 14 are arranged in an X-shape. An iron plate or the like may be used instead of the reinforcing bar 14.

A rectangular first iron plate 15 having a predetermined strength is fixed to an end of the X-type reinforcing bar 14 or the vertical and horizontal reinforcing bars 13, in this example, at four corners (or arbitrary positions) of the earthquake-resistant wall 10 by welding. I have. The end of the reinforcing bar 14 is fixed to the first iron plate 15 by welding. The first iron plate 15 is embedded in the concrete of the earthquake-resistant wall 10, and a part of the first iron plate 15 projects out of the concrete.

On the other hand, the first and second beams 12
The second iron plate 17 is fixed to the iron plate 15 by welding or other methods. Part of the second iron plate 17 is also a beam 12
And partly project outside. The connection between the second iron plate 7 and the beam 12 may be made by any method as long as it is mutually strong. In addition, a beam to which the first iron plate 15 can be attached is embedded in the beam 12, and the first
An iron plate 15 can also be attached.

The first iron plate 15 of the earthquake-resistant wall 10 and the second iron plate 12 of the beam 12
As shown in FIG. 2, a portion protruding from the earthquake-resistant wall 10 and a portion protruding from the beam 12 are overlapped with the iron plate 17, and are joined by being fastened with an appropriate number of bolts 18 and nuts 19. Thereby, the earthquake-resistant wall 10 is securely attached to the beam 12. Earthquake-resistant wall 10 is upper and lower beams 1
After being attached to 2, 12, the shear wall 10 and columns 11, 1
The gap between 1 and beams 12, 12 is filled with concrete or mortar.

As described above, in the mounting structure 1 of the earthquake-resistant wall, the first iron plate 15 of the earthquake-resistant wall 10 and the second iron plate 17 of the beams 12, 12 to which the earthquake-resistant wall 10 is to be fixed by the bolts 18 and the nuts 19. Since it can be fixed simply by fastening, it is possible to greatly reduce the number of construction steps as compared with the conventional case where the main reinforcement 13 of the earthquake-resistant wall 10 and the main reinforcement 16 of the beam 12 are fixed by a sleeve joint or welding. it can.

FIG. 3 shows a mounting structure 2 for a shear wall according to another embodiment of the present invention. The mounting structure 2 for the earthquake-resistant wall includes columns 11 and 11 and beams 1 like the mounting structure 1 for the earthquake-resistant wall described above.
An earthquake-resistant wall 20 is arranged between 2 and 12, and the earthquake-resistant wall 20 is fixed to the beams 12 and 12. The earthquake-resistant wall 20 is precast and is divided into a plurality of blocks. In the present example, two slits 21 and 22 having an appropriate length are provided at three equally spaced positions of the width of the earthquake-resistant wall 20, whereby the whole is divided into three blocks.

Each block divided by the slits 21 and 22 is provided with a vertical and horizontal 23 and an X-shaped reinforcing bar 24, respectively. Further, first iron plates 25 are fixed to the reinforcing bars 24 at the four corners of the earthquake-resistant wall 20 by welding. First

A second iron plate 27 is fixed to the beam 12 so as to correspond to the first iron plate 25. Then, the first iron plate 25 of the earthquake-resistant wall 20 and the second iron plate 27 of the beam 12 are superimposed, fastened by bolts 18 and nuts, and fixed.

In the mounting structure 2 for the earthquake-resistant wall, the earthquake-resistant wall 20 is formed by a plurality of slits 21 and 22,
Since it is divided into individual blocks, the rigidity is lower than in the case where the earthquake-resistant wall 20 is integrated. By doing so, it is possible to balance the rigidity of the earthquake-resistant wall 20 with a low rigidity portion provided with an opening (not shown) such as a window or a door, so that the columns 11 and the beams 12 need to be reinforced. Disappears. Therefore, the number of construction steps can be reduced. The number of divisions of the earthquake-resistant wall 20 is set to be rigid so as to balance the rigidity of the other parts to which it is attached. As the number of divisions increases, the rigidity of the earthquake-resistant wall 20 decreases.

In the above embodiment, the earthquake-resistant wall 1
Although the case where 0 and 20 are attached to the beam 12 has been described, the same applies to the case where the earthquake-resistant walls 10 and 20 are attached to the column 11. In the above-described embodiment, the slits 21 and 2
Although the case where the center part of the earthquake-resistant wall 20 is separated and divided into a plurality of blocks according to 2 has been described, the earthquake-resistant wall 20 may be completely separated and divided into a plurality of blocks.

[0019]

As described above, according to the mounting structure of the earthquake-resistant wall of the present invention, the first plate material fixed to the main reinforcement of the earthquake-resistant wall and the second plate material fixed to the column or the beam are fixed. By itself, the earthquake-resistant wall and the column or the beam can be easily joined. Therefore, the number of construction steps required for attaching the earthquake-resistant wall can be reduced.

When the rigidity of the earthquake-resistant wall is divided into a plurality of blocks to adjust the rigidity, and the rigidity of the earthquake-resistant wall and parts other than the earthquake-resistant wall are harmonized, there is no need to reinforce columns and beams, and the number of construction steps is reduced. Can be reduced.
