  In the seismic strengthening methods of Patent Documents 1 to 3, the seismic wall is made of a rigid channel steel or steel plate in order to exhibit sufficient seismic performance. For this reason, the seismic walls are heavy, and it is necessary to reinforce underground structures such as piles and pillars that support the building, and upper structures of beams. That is, there is a problem that the reinforcement work is large and not only the construction period is lengthened but also the cost is increased.

  In addition, since channel steel and steel plate exhibit great rigidity and proof strength against axial force, concrete creep and drying shrinkage due to the long-term load of the building, reinforced concrete structure or steel reinforced concrete structure. Axial force originating from is transmitted to the underground and upper frame. For this reason, it is necessary to reinforce the underground and upper frames, which requires a large amount of reinforcement work and not only lengthens the construction period but also increases costs.

  By the way, paying attention to the mechanical characteristics of the corrugated steel sheet, the following features are recognized. The corrugated steel sheet is also simply referred to as a folded plate or a corrugated sheet, and the cross-sectional shapes include a trapezoidal wave shape (A) and a rectangular wave shape (B) illustrated in FIGS. 21 (A) to (D). , Triangular wave shape (C), circular wave shape (D), and the like.

(For shear force)

As illustrated in FIG. 17, in the corrugated steel sheet, each one of the folded plates resists the shearing force, and the whole as a set resists the shearing force. And when shear buckling length is short and the shear strength is compared with a flat plate, shear strength is much larger.

  On the other hand, as illustrated in FIG. 18, the shearing force perpendicular to the corrugated steel bar does not resist the shear force extending freely like an accordion.

  (For axial force and bending)

As shown in FIG. 19, the axial force perpendicular to the corrugated steel strip expands and contracts freely like an accordion, and its rigidity and proof stress are much smaller than those of a flat plate. Also, with respect to in-plane bending, as shown in FIG. 20, it expands and contracts freely like an accordion, and its rigidity and proof stress are much smaller than that of a flat plate.

  However, since the corrugated steel sheet of Patent Document 4 is adopted as a disaster-shielding wall, there is no technical idea for yielding the corrugated steel sheet to absorb seismic energy, and a seismic control effect cannot be expected.

Accordingly, an object of the present invention is to fit a corrugated steel sheet having the above-mentioned mechanical characteristics into a plane of a column / beam frame or a column / slab frame of an existing building with the reinforcing bars of the corrugated steel sheet facing the horizontal direction. Therefore, the existing building can be seismically reinforced with a structure that is lightweight and does not transmit axial force to the underground or upper frame, and therefore the reinforcement of the underground or upper frame is almost unnecessary, facilitating construction.

  In the seismic reinforcement method for an existing building according to the present invention, each corrugated steel sheet fitted as a reinforcing member in the frame surface resists shearing force one by one, and the whole as a set shears. Because it is resistant to force, the rigidity of the frame is increased, and the corrugated steel plate resists the horizontal force caused by the earthquake and exhibits a sufficient seismic effect.

  In other words, corrugated steel sheets are lighter than flat plates but exhibit sufficient seismic performance, so existing buildings can be seismically reinforced with a lightweight construction, and can be used for underground structures such as piles, columns, and upper structures of beams. There is little need to reinforce. Therefore, it is easy to install seismic reinforcement, which can contribute to shortening the construction period and reducing costs.

For this reason, it is not necessary to reinforce the underground frame or the upper frame, and it is easy to perform seismic reinforcement, contributing to shortening the construction period and reducing costs.

  Moreover, since the corrugated steel sheet can be yielded and the seismic energy can be absorbed, a high seismic control effect can be exhibited.

  A corrugated steel plate is fitted as a reinforcing member in the plane of a column / beam frame or a column / slab frame of an existing building, and the reinforcement is fitted in the horizontal direction so that horizontal force can be transmitted between the frame and the frame.

Embodiments of the seismic reinforcement method for an existing building according to the inventions described in claims 1 , 2 , 3, 10 , and 13 will be described with reference to FIGS. 1 and 2.

  The embodiment shown in FIGS. 1 and 2 is reinforced by fitting a corrugated steel plate 4 with a frame as a reinforcing member in a plane of a frame 3 formed by columns 1 and beams 2 of an existing building of reinforced concrete structure or steel reinforced concrete structure. is doing.

  Specifically, the stud 5 is first attached to the entire inner peripheral surface of the frame 3.

The corrugated steel sheet 4 with a frame to be fitted in the surface of the frame 3 is a single corrugated steel sheet 6 made of low yield point steel, and a stud 7 is attached to each outer peripheral side of the corrugated steel sheet 6. The frame 9 is formed by joining the plates 8 and is assembled in advance at a factory or the like and carried into a site (claims 10 and 13 ). Incidentally, the thickness of the corrugated steel sheet 6 (typically about 9 mm to 22 mm), the pitch of the corrugation (typically about 500 mm to 700 mm), and the magnitude of the wave height (typically about 80 mm to 150 mm) are set to a predetermined shear strength and rigidity. Is designed to express.

  In the surface of the frame 3, the corrugated steel plate 4 with the above-mentioned structure is fitted with the stripes of the unit corrugated steel plate 6 facing the horizontal direction, and the inner peripheral surface of the frame 3 and the outer peripheral surface of the frame of the corrugated steel plate 4 with the frame In between, the non-shrink mortar 10 is filled. As a result, it becomes the structure which can transmit a horizontal force between the unit corrugated steel plate 6 and the frame 3 of the corrugated steel plate 4 with the frame, and as described above, the unit corrugated steel plate 6 is a folded plate one by one. Is resistant to shearing force and the aggregate as a whole is resistant to shearing force (see FIG. 17), so that the rigidity of the frame 3 is increased, and the unit corrugated steel plate 6 resists the horizontal force due to the earthquake and is sufficient. Demonstrate earthquake resistance.

  In other words, the unit corrugated steel sheet 6 of the corrugated steel sheet 4 with a frame is lighter than a flat plate and exhibits sufficient seismic performance. Therefore, the existing building can be seismically reinforced with a light construction, and underground structures such as piles. There is little influence on the upper frame of the column 1 and the beam 2 and there is almost no need to reinforce. Therefore, it is easy to install seismic reinforcement, which can contribute to shortening the construction period and reducing costs.

  In addition, the unit corrugated steel plate 6 of the corrugated steel plate 4 with the frame is free from expansion and contraction with respect to the axial force, as described above, so that it does not resist. Therefore, the creep of the concrete because it is reinforced concrete or steel reinforced concrete. The axial force originating from the drying shrinkage is not transmitted to the underground frame or the upper frame (see FIG. 19). For this reason, it is not necessary to reinforce the underground frame or the upper frame, and it is easy to perform seismic reinforcement, contributing to shortening the construction period and reducing costs.

  In addition, since the unit corrugated steel sheet 6 of the corrugated steel sheet 4 with a frame can be yielded and seismic energy can be absorbed, a high seismic control effect can be exhibited.
