Description

本発明は、構造物の開口部の耐震補強装置及びこれを用いた耐震補強工法に係り、さらに詳しくは、多数の建具や窓枠などを設置するための開口部の形成によって、耐震性が劣ることを防止できる構造物の開口部の耐震補強装置及びこれを用いた耐震補強工法に関する。   The present invention relates to a seismic reinforcement device for an opening of a structure and a seismic reinforcement method using the same, and more particularly, the seismic resistance is inferior due to the formation of openings for installing a large number of fittings and window frames. The present invention relates to a seismic reinforcement device for an opening of a structure that can prevent this and a seismic reinforcement method using the same.

一般に建築構造物または土木構造物には窓(建具)、出入り口、間仕切などを設置するための開口部が設けられている。かかる開口部には、一定サイズ以上の開口空間(void space)を確保した後、開口空間の内側面に建具、アルミニウムサッシ、付帯設備などを挿入して固定することが普通である。   In general, a building structure or a civil engineering structure is provided with an opening for installing windows (joint), doorways, partitions, and the like. Usually, an opening space (void space) of a certain size or more is secured in such an opening, and then a fitting, an aluminum sash, incidental equipment, or the like is inserted and fixed on the inner surface of the opening space.

かかる開口部は、コンクリート建物や組積式建物などの多様な建築構造物において、他の部分に比べて応力集中が激しいことが知られている。特に、地震や台風などによって振動が発生する場合、建築構造物の開口部から引張り割れが発生するので、多くの開口部を有する建物は、地震や強風に極めて弱いものと知られている。   Such an opening is known to have a greater stress concentration in various building structures such as a concrete building and a masonry type building than in other parts. In particular, when vibration is generated by an earthquake or a typhoon, a tensile crack is generated from an opening of a building structure. Therefore, a building having many openings is known to be extremely vulnerable to an earthquake or strong wind.

耐震設計が反映されていないコンクリート建物の場合、耐震性能が不十分なことから、開口部から起因する構造の損傷によって、地震の発生時に多大な被害を引き起こすことが確認されている。   In the case of concrete buildings that do not reflect seismic design, the seismic performance is inadequate, and it has been confirmed that structural damage caused by the opening causes great damage when an earthquake occurs.

かかる地震から人的被害及び物的被害を最小化するために、建物の開口部または柱や梁のような構造部材には、多様な制震装置が設けられている。制震装置を用いた耐震補強工法は現在建物構造物の新築工事及びリモデリング工事に一般的に活用されている。例えば、前記制震装置は構造部材であるフレームに対角方向のブレース型ダンパーを設けて、地震によって反復的に荷重を受ける間、焼成履歴挙動によってエネルギーを消散させることによって建物の損傷を最小化するようになる。   In order to minimize human damage and property damage from such an earthquake, a variety of vibration control devices are provided in building openings or structural members such as columns and beams. Seismic retrofitting methods using seismic control devices are now commonly used for new construction and remodeling of building structures. For example, the seismic control device is provided with diagonal brace-type dampers on the structural frame, which minimizes damage to the building by dissipating energy through firing history behavior during repeated loads due to earthquakes. To come.

しかし、かかる一般の制震装置は、ダンパーを設けるために柱や梁のような大きな剛性を有する構造部材(ダンパー保持用)を必要とするので、施工が煩雑化するのみならず、別の設置空間を確保する必要があるという問題点があった。また、鉄筋コンクリート建物は、ダンパーのための別の設置空間を確保し難いので、制震装置の設置が難しく、特に耐震性能に劣る低い建物には適していないとの問題点がある。   However, since such a general vibration control device requires a structural member (for holding a damper) having a large rigidity such as a column or a beam in order to provide a damper, not only the construction becomes complicated, but also another installation. There was a problem that it was necessary to secure space. In addition, since it is difficult to secure another installation space for the damper, the reinforced concrete building has a problem that it is difficult to install a vibration control device, and is not suitable for a particularly low-damaged building.

かかる点に鑑みて、韓国特許登録第０３４８５７７号には、建物の開口部に設けられた水平梁型ダンパーを用いた耐震補強工法が開示されている。   In view of this point, Korean Patent Registration No. 0348577 discloses a seismic reinforcement method using a horizontal beam type damper provided in an opening of a building.

上記耐震補強工法は、梁の中央部の底面に中央ジグを固定させて地震荷重による梁の撓み変形が中央Ｔ字形ジグに伝達されるようにし、前記柱部の内側面にダンパーフレームを設け、前記中央Ｔ字形ジグとダンパーフレームとの間に水平梁型ダンパーを設け、前記水平梁型ダンパーを開口部の上部に位置させる工程を含む。   The seismic reinforcement method is to fix the center jig to the bottom surface of the center of the beam so that the bending deformation of the beam due to the seismic load is transmitted to the center T-shaped jig, and to provide a damper frame on the inner surface of the column, A step of providing a horizontal beam type damper between the central T-shaped jig and the damper frame, and positioning the horizontal beam type damper on an upper portion of the opening;

韓国特許登録第１１６１７８５号には、耐震性能を有する一体型の建具システムが開示されている。この特許の技術的構成には、開口された空間の一部をブレースとダンパーが遮られる問題点があり、地震に対して十分なダンピング力の確保が難しい。   Korean Patent Registration No. 1161785 discloses an integrated joinery system having seismic performance. The technical configuration of this patent has a problem that the brace and the damper are blocked by a part of the opened space, and it is difficult to secure a sufficient damping force against an earthquake.

韓国特許登録第１１６５３２０号には、鉄筋コンクリート建物の開口部の耐震補強方法が開示されている。この耐震補強方法は、開口部の鉄骨フレームに設けられるダンパーを用いずに、地震による水平力を鉄筋コンクリートの下部壁体に埋め込まれた鉄骨フレームで抵抗するようになる。   Korean Patent Registration No. 1165320 discloses a method for seismic reinforcement of openings in reinforced concrete buildings. In this seismic reinforcement method, the horizontal force caused by the earthquake is resisted by the steel frame embedded in the lower wall of the reinforced concrete without using the damper provided in the steel frame of the opening.

上記耐震補強方法は、鉄筋コンクリートの下部壁体に埋め込まれた鉄骨フレームに角補強材をさらに備え、単に構造的強度を補ったものであって、建物の設計によるコストアップの原因になり、角補強材が設けられている点によって建物の開口部が沈みこむ問題がある。   The above-mentioned seismic reinforcement method is a structure in which a steel frame embedded in the lower wall of reinforced concrete is further provided with a corner reinforcing material, which simply supplements the structural strength. There is a problem that the opening of the building sinks due to the material provided.

韓国特許登録第１２９７７９４号には構造物の開口部の耐震補強工事のための外部飛階設置構造及びその設置方法を適用した耐震補強工法が開示されており、韓国特許登録第１２８１２０６号には建物の開口部用の免震装置及びその製造方法が開示されており、韓国特許登録第１３７９８９２号には可変型鉄骨フレームによる構造物の開口部の耐震補強構造及びその施工方法が開示されている。   Korean Patent Registration No. 1297794 discloses an external flying floor installation structure for seismic reinforcement work of the opening of a structure and a seismic reinforcement method using the installation method. Korean Patent Registration No. 1281206 discloses a building. A seismic isolation device for an opening and a manufacturing method thereof are disclosed, and Korean Patent Registration No. 1379892 discloses a seismic reinforcement structure for an opening of a structure using a variable steel frame and a method for its construction.

In addition, the present invention provides a seismic reinforcement device for an opening of a building capable of improving the seismic performance and a seismic reinforcement method using the same.

本発明の他の目的は、多数の開口部による建物の弱化が原因となって地震、強風などによって建物が壊れることを防止できる建物の開口部の耐震補強装置及びこれを用いた耐震補強工法を提供するところにある。   Another object of the present invention is to provide a seismic reinforcement device for a building opening that can prevent the building from being broken by earthquakes, strong winds, etc. due to weakening of the building by a large number of openings, and a seismic reinforcement method using the same. There is to offer.
