Description of the Related Art In the wake of the Hyogoken-Nanbu Earthquake, it has become an urgent and important task to improve the seismic resistance of so-called existing ineligible buildings with insufficient seismic performance. Techniques to improve the seismic resistance of existing buildings include strengthening the strength and rigidity by adding load-bearing walls and braces, and rolling up steel plates on columns to improve toughness and improve deformability. Various devices have been proposed and put into practical use, such as installing a damping damper to improve damping performance.

This is achieved, for example, by fixing a panel-shaped damping frame 2 made of extremely mild steel and a rectangular frame-shaped damping frame 4 incorporating a brace material 3 connected thereto to the frame of the existing building 1 during an earthquake. Is transmitted to each damping damper 2 via the damping frame 4 and the brace material 3 to obtain the damping effect.

4の固定は次のようにして行うことが通常である。In this case, as shown in FIG. 6, the damping frame 4 is made independent for each floor, and is fixed in a structure surrounded by columns 5 and beams 6 on each floor, or as shown in FIG. As described above, the vibration control frames 4 of each floor are made continuous over all floors of the existing building 1 and the series of the vibration control frames 4 are fixed outside the outer peripheral surface of the existing building 1 (that is, installed on the outer wall). In any case, the inter-story deformation of the existing building 1 is
In order to transmit the vibration control damper 2 to the damper 2 securely via the bridge, it is necessary to securely fix the vibration control frame 4 to the frame of the existing building 1. Therefore, the fixing of the frame 4 to the frame is performed as follows. It is usual to do so.

A large number of studs are densely mounted around the entire circumference, and a large number of post-installed anchors are densely provided over the entire length of the columns 5 and beams 6 where the damping frame 4 is to be installed. The post-installed anchor is engaged directly or indirectly, and in that state, concrete or mortar 7 is poured into the gap between the vibration control frame 4 and the columns 5 and the beams 6 as shown in FIG. And the retrofitting anchor are fixed to each other.

It is required that the reinforcement does not significantly reduce the livability, function, and usability of the existing building, and that the reinforcement work can be performed in the shortest possible time while using the existing building.

とが実状であり、有効な改善策が望まれていた。However, in the case of the conventional vibration damping reinforcement structure shown in FIGS. 6 and 7, when fixing the vibration damping frame 4, an enormous number of post-construction anchors are provided for the frame of the existing building 1. Not only requires a great deal of construction work, but also the construction site extends over the entire existing building 1, and therefore the construction period is necessarily long, and construction using the existing building 1 as it is is almost impossible. The fact is that effective improvement measures have been desired.

Similar to the structure shown in FIG. 7, a series of vibration control frames 4 incorporating the vibration dampers 2 and the brace materials 3 on each floor are basically installed outside the outer peripheral surface of the existing building 1. However, conventionally, such a vibration control frame 4
Is fixed over the entire length of the pillars 5 and the beams 6 of the existing building 1, whereas in the present embodiment, only the corners of the vibration control frame 4 on each floor are substantially pin-joined via the joint members 8. In this embodiment, the structure is joined to the frame of the existing building 1.

に対して固定するようになっている。FIG. 2 shows a joint (FIG. 1) of the joining member 8.
In section II). The joining member 8 is made of a short H-section steel having a small cross section directly welded to a corner of the vibration control frame 4, and a base plate 9 is welded to a tip of the H-section steel 8. 9 are fixed to the frame of the existing building 1 by a plurality of post-installed anchors 10 (10 in the illustrated example), and the vibration damping frame 4 is attached to the existing building 1 only by the joining members 8.
To be fixed against.

接合の形態では過大な捻りトルクの伝達がなされず、こ
れは実質的にピン接合とみなすことができるものであ
る。When the H-section steel having a small cross section is used as the joining member 8 as described above, the interlayer deformation occurring in the existing building 1 at the time of an earthquake is transmitted to the vibration control frame 4 via these joining members 8 as a shearing force. The vibration is transmitted from the vibration frame 4 to the vibration damper 2 via the brace material 3 without any trouble, and the vibration damping effect of the vibration damper 2 is obtained. When the above-mentioned interlayer deformation occurs, not only a shear force but also a torsional torque acts on each joint member 8, and the torsional torque is absorbed by the elastically torsional deformation of the joint member 8 itself. Therefore, in such a form of joining by the joining member 8, excessive torsion torque is not transmitted, and this can be regarded as substantially a pin joining.

ものとなって弾性的な捻れ変形を期待できるから、これ
による接合の形態は捻りトルクを十分には伝達し得ない
ピン接合と見なせるのである。That is, when it is assumed that a closed section member such as a steel pipe or a solid steel material is used as the joining member 8, such a closed section member is excellent not only in shear rigidity but also in torsional rigidity. In this connection, the form of joining is naturally rigid, and not only the shearing force but also the torsional torque is transmitted. However, as in the present embodiment, the joining member 8 is an open section of a small section such as an H-section steel. When a member is used, its torsional rigidity is appropriately reduced as compared with a closed cross-section member, and elastic torsional deformation can be expected. It can be regarded as joining.

ー10に要求される捻り剛性も軽減することができる。When a closed section member having high torsional rigidity is used as the joining member, the post-installed anchor 10 for fixing the same to the existing building 1 needs to have the same or higher torsional rigidity. Inevitably, a large number of high-strength post-installed anchors are required. However, by using an open section member such as an H-section steel as the joining member 8 as in the present embodiment, the torsional rigidity is appropriately reduced. Also, the torsional rigidity required for the post-installed anchor 10 can be reduced.
【0016】それ故に、本実施形態では各接合部材8を

に比べて制震フレーム4の設置作業を大幅に軽減でき、
工期も大幅に短縮することが可能である。Therefore, in the present embodiment, it is sufficient to fix each connecting member 8 to the frame of the existing building 1 by only about ten post-installed anchors 10, and it is sufficient to use the entire length of the vibration control frame 4 as in the conventional case. It is sufficient to fix only the corners of each vibration control frame 4 with the joint members 8 without fixing the entire length of the pillars 5 and the beams 6, and as shown in the drawing, the existing building 1 is an eight-story building. Even in this case, only 18 joints are required at two places on each floor, and the work of installing the damping frame 4 can be greatly reduced as compared with the conventional case.
The construction period can be significantly reduced.

うことも可能となる。Moreover, since a series of vibration damping frames 4 are installed outside the structure of the frame of the outer peripheral part of the existing building 1, that is, on the outer wall, the vibration damping frame 4 can be operated only from outside the existing building 1. 4 can be installed and work in the building can be made almost unnecessary. As a result, the livability, function, and usability of the existing building 1 are not significantly impaired, and the construction can be performed while using the existing building 1 as it is. This can be done in a short time.
【0018】なお、接合部材8としては上記実施形態の

必要であれば文字どうりピンを用いた本来のピン接合と
することも妨げるものではない。Although it is optimal and practical to use an H-section steel having a small cross section as in the above embodiment, the joining member 8 has an appropriate torsional rigidity that can be regarded as substantially a pin joint. If so, for example, another open-section steel material such as an angle material or a T-bar may be used.
If necessary, it does not prevent the actual pin connection using the pin from the character.

ことでも良い。Further, in the above embodiment, the joining member 8 is fixed to the connection between the column 5 and the beam 6 of the existing building 1, but depending on the scale and form of the building, for example, as shown in FIG. As described above, the joining member 8 may be fixed to the intermediate portion of the beam 6.

Can be changed, and for example, an eccentric K-shaped brace damper as shown in FIGS. 4 and 5 can be adopted. This is because the horizontal member 11 of the vibration damping frame 4 is
The horizontal member 11 is expanded and contracted in the axial direction by 2.
It makes itself function as a vibration damper,
FIG. 4 shows such a vibration damper 11 and a connecting member 12.
Is connected to the connection between the pillar 5 and the beam 6 on each floor by the same connecting member 8 as described above. FIG. 5 shows the middle of the beam 6 on each floor. And the same effect as in the above embodiment can be obtained.

る。As described above, according to the first aspect of the present invention, the corner of the damping frame incorporating the damping damper is substantially pin-joined to the outside of the frame of the existing building.
The transmission of torsional torque can be reduced while the shearing force is transmitted to the seismic control frame during inter-story deformation of the existing building, and therefore, the connecting members for performing such connection are fixed to the existing building. It is not necessary for the anchors to have much torsional rigidity, so the required strength and number of anchors can be significantly reduced, and as a result, construction work to install a vibration control frame on existing buildings is required. It can be greatly simplified, and can greatly contribute to reduction of construction cost and construction period.

である。The invention according to claim 2 uses an open-section steel material such as an H-section steel having a low torsional rigidity as compared with the shear rigidity as the joining member, and therefore uses an inexpensive steel material as a normal construction material. Substantial pin bonding can be realized, which is extremely reasonable.

The work inside the building can be almost unnecessary, and as a result, the livability, function and usability of the existing building are not significantly impaired, and the work can be performed in a short time while using the existing building as it is.
