A connecting member 9 having a horizontal portion and a vertical portion on the outer surface of the concrete beam 6 is fixed with anchor bolts 8 across the portion to be reinforced of the concrete beam 6. A connecting bolt hole 9 a is formed in the vertical portion of the connecting member 9. The connecting bolt 10 is inserted into the connecting bolt hole 9 a of the connecting member 9 and the connecting bolt hole 7 e formed in the main body portion 7 a of the reinforcing member 7, and a nut is screwed onto the male thread portion of the connecting bolt 10 to connect the connecting bolt 10. 9 and the reinforcing member 7 are connected.

The post-construction anchor 11 promotes the integration of the concrete pillar 5 and the high-strength concrete to improve the earthquake resistance. The reinforcing member 7 is connected to the connecting member 9 with a connecting bolt 10. A reinforcing bar 12 is arranged in the gap between the reinforcing member 7 and the concrete beam 6.

A continuous fiber sheet may be applied to the outer periphery of the reinforcing member 7 to improve energy attenuation and tensile strength.

図7は、耐震補強されたコンクリート柱5の耐震補強部とコンクリート梁6の耐震補強部に図1、図2に示す制振補強部材1を配置した実施形態を示す図であり、図8、図9はその一部拡大図である。   FIG. 7 is a view showing an embodiment in which the vibration-damping reinforcement member 1 shown in FIGS. 1 and 2 is arranged in the earthquake-proof reinforcement part of the concrete column 5 subjected to earthquake-proof reinforcement and the earthquake-proof reinforcement part of the concrete beam 6. FIG. 9 is a partially enlarged view thereof.

制振補強部材1の両端を接合するコンクリート梁6の耐震補強部、コンクリート柱5の耐震補強部と面接触する形状に切断する。図7に示す実施形態では、2本の制振補強部材1の一端をコンクリート梁6の耐震補強部に面接触させ、他端をコンクリート柱5の耐震補強部とコンクリート梁の耐震補強部との交差部に面接触させている。但し、制振補強部材1の配置は、図に示す実施形態に限定されるものではない。   The vibration suppression reinforcement member 1 is cut into a shape that is in surface contact with the seismic reinforcement portion of the concrete beam 6 that joins both ends of the vibration damping reinforcement member 1 and the seismic reinforcement portion of the concrete column 5. In the embodiment shown in FIG. 7, one end of the two vibration damping reinforcing members 1 is brought into surface contact with the seismic reinforcing portion of the concrete beam 6, and the other end is connected to the seismic reinforcing portion of the concrete column 5 and the seismic reinforcing portion of the concrete beam. Surface contact is made at the intersection. However, the arrangement of the vibration damping reinforcing member 1 is not limited to the embodiment shown in the drawing.

制振補強部材1をコンクリート柱5の耐震補強部とコンクリート梁6の耐震補強部に配置固定する手順を説明する。先ず、固定部材13をコンクリート柱5を耐震補強する補強部材7とコンクリート梁6を耐震補強する補強部材7に固定する。固定部材13は、補強部材7と面接触する部分と制振補強部材1と面接触する部分を有し、補強部材7とコンクリート柱5、コンクリート梁6の間隙に高強度コンクリートが充填される前に、固定部材13と面接触する補強部材7に固定部材13に形成した固定ボルト用孔に対応する位置に固定部材固定ボルト用孔を形成し、固定ボルト14のヘッドが補強部材7の内側に位置するように挿入し固定ボルト14の雄ネジ部にナットを螺着して固定部材13を補強部材7に固定する。高強度コンクリートモルタルの充填前であるのでシール部材を介してナットを螺着するのが望ましい。   A procedure for arranging and fixing the vibration damping reinforcement member 1 on the seismic reinforcement part of the concrete column 5 and the seismic reinforcement part of the concrete beam 6 will be described. First, the fixing member 13 is fixed to the reinforcing member 7 that seismically reinforces the concrete column 5 and the reinforcing member 7 that seismically reinforces the concrete beam 6. The fixing member 13 has a portion that is in surface contact with the reinforcing member 7 and a portion that is in surface contact with the vibration damping reinforcing member 1, and before the high-strength concrete is filled in the gap between the reinforcing member 7, the concrete column 5, and the concrete beam 6. The fixing member fixing bolt hole is formed at a position corresponding to the fixing bolt hole formed in the fixing member 13 in the reinforcing member 7 in surface contact with the fixing member 13, and the head of the fixing bolt 14 is located inside the reinforcing member 7. The fixing member 13 is fixed to the reinforcing member 7 by being inserted so as to be positioned and screwing a nut onto the male screw portion of the fixing bolt 14. Since it is before filling with high-strength concrete mortar, it is desirable to screw a nut through a seal member.

固定部材13を補強部材に固定した後、制振補強部材1を固定部材13と面接触するように配置する。制振補強部材1の固定部材と面接触する部分に固定部材13に形成した固定ボルト用孔に対応する位置に固定部材固定ボルト用孔を形成し、固定ボルト14のヘッドが制振補強部材1のフランジの内側に位置するように挿入し固定ボルト14の雄ネジ部にナットを螺着して制振補強部材1を固定部材13に固定する。図7、図8に示す実施形態では、制振補強部材1にのみ面接触する固定部材13が存在するが、この固定部材13と制振補強部材1を前述のように固定する。   After fixing the fixing member 13 to the reinforcing member, the vibration-damping reinforcing member 1 is disposed so as to be in surface contact with the fixing member 13. A fixing bolt hole is formed at a position corresponding to the fixing bolt hole formed in the fixing member 13 at a portion in surface contact with the fixing member of the vibration damping reinforcing member 1, and the head of the fixing bolt 14 is connected to the vibration damping reinforcing member 1. The damping reinforcement member 1 is fixed to the fixing member 13 by inserting the nut so as to be positioned inside the flange of the fixing bolt 14 and screwing a nut onto the male screw portion of the fixing bolt 14. In the embodiment shown in FIGS. 7 and 8, there is a fixing member 13 that is in surface contact only with the vibration damping reinforcing member 1. The fixing member 13 and the vibration damping reinforcing member 1 are fixed as described above.

高強度コンクリートモルタルの充填の時期は、補強部材7への固定部材13が固定された後で、制振補強部材1の設置の前が望ましい。高強度コンクリートモルタルの充填、固化の前に制振補強部材1を設置すると、制振補強部材1の荷重がコンクリート柱5、コンクリート梁6が連結ボルト10でのみ連結された補強部材7に負荷され連結ボルト10が破損する恐れがあるからである。   The timing of filling the high-strength concrete mortar is preferably after the fixing member 13 is fixed to the reinforcing member 7 and before the vibration-damping reinforcing member 1 is installed. If the vibration-damping reinforcement member 1 is installed before filling and solidifying the high-strength concrete mortar, the load of the vibration-damping reinforcement member 1 is applied to the reinforcing member 7 in which the concrete column 5 and the concrete beam 6 are connected only by the connecting bolt 10. This is because the connecting bolt 10 may be damaged.

高強度コンクリートモルタルが補強部材7とコンクリート柱5、コンクリート梁6との間隙に充填、固化されコンクリート柱5、コンクリート梁6と補強部材7が一体化されコンクリート柱5、コンクリート梁6が耐震補強される。コンクリート柱5とコンクリート梁6の耐震補強された部分に制振補強部材1が固定部材13を介して一体化され、コンクリート構造物の制振及び耐震補強構造となる。   High-strength concrete mortar is filled in the gap between the reinforcing member 7 and the concrete column 5 and the concrete beam 6 and solidified. The The vibration damping reinforcement member 1 is integrated with the portions of the concrete pillar 5 and the concrete beam 6 which are reinforced against earthquakes via a fixing member 13 to form a vibration damping and earthquake proof reinforcement structure for the concrete structure.

以上のように、本発明のコンクリート構造物の制振及び耐震補強構造によれば、制振補強部材が連続繊維シートをサンドイッチ状に一体化することで制振性、耐震性を向上させつつ小型軽量化を図ることが可能となり、制振補強部材とコンクリート柱、コンクリート梁の耐震補強部を一体化することでコンクリート構造物の制振制及び耐震性を相乗効果で著しく向上することが可能となる。   As described above, according to the vibration damping and seismic reinforcement structure of the concrete structure of the present invention, the vibration damping reinforcement member integrates the continuous fiber sheet into a sandwich shape, thereby improving the vibration damping performance and the earthquake resistance. It is possible to reduce the weight, and by integrating the vibration-damping reinforcement member, the concrete pillar, and the earthquake-resistant reinforcement part of the concrete beam, it is possible to remarkably improve the vibration damping and earthquake resistance of the concrete structure with a synergistic effect.
