しかしながら、プレハブ化された軽量鉄骨造建築物に関し、柱の振れを抑制するためにコンクリート製品を組み合わせた振動抑制構造としたものはみあたらない。   However, there are no prefabricated lightweight steel structures that have a vibration suppression structure that combines concrete products to suppress column runout.

解決しようとする問題点は、プレハブ化された軽量鉄骨造建築物の柱の振れを抑制することにあり、具体的には、出隅部にコンクリート製のコーナーサポートを設けて振動抑制構造とすることにある。   The problem to be solved is to suppress the run-out of the pillars of the prefabricated lightweight steel structure. Specifically, the corner support made of concrete is provided at the exit corner to provide a vibration suppression structure. There is.

本発明はこのような事情に鑑みなされたものであって、上記課題を解消し、プレハブ化された軽量鉄骨造建築物の出隅部にコンクリート製のコーナーサポートを設けて振動抑制構造を有するようにした軽量鉄骨造建築物を提供するものである。   This invention is made | formed in view of such a situation, Comprising: The said subject is solved, and the corner support made from concrete is provided in the projecting corner part of the lightweight steel frame building prefabricated, and it has a vibration suppression structure. It provides a lightweight steel structure.

課題を解決するために本発明は、プレハブ化された軽量鉄骨造建築物において、
出隅部にコンクリート製のコーナーサポートを設けた振動抑制構造を有する軽量鉄骨造建築物であって、
布基礎に立設した隅柱に対向する隅角面を形成したコンクリート支持体を添設するとともに、該コンクリート支持体を前記布基礎と一体化又は剛接合して立ち上げ、前記隅柱との面間に粘弾性材又は振動吸収材を介設してなることを特徴とするものである。
In order to solve the problem, the present invention provides a prefabricated lightweight steel structure,
A lightweight steel structure having a vibration suppression structure with a corner support made of concrete in the protruding corner,
A concrete support having a corner surface facing the corner pillar standing on the fabric foundation is added, and the concrete support is integrated with or rigidly joined to the cloth foundation and is raised. A viscoelastic material or a vibration absorbing material is interposed between the surfaces.

本発明によれば、隅柱に対してコンクリート製のコーナーサポートを設け、かつ、布基礎と一体化又は剛接合して立ち上げているので、柱の振れを効果的に抑制することができる。   According to the present invention, the corner support made of concrete is provided for the corner column, and the column foundation is integrated with or rigidly joined to the fabric foundation, so that it is possible to effectively suppress the deflection of the column.

本発明の実施の最良形態は、上記構成において、コンクリート支持体が、断面視L形の隅角面を有する鉄筋コンクリート(RC)であって、布基礎の構築とともに現場打設されものとしている。もちろん、プレキャスト製品を布基礎に剛接合することも考慮されてよい。   In the above configuration, the best mode for carrying out the present invention is such that the concrete support is reinforced concrete (RC) having an L-shaped corner surface in cross section, and is placed on-site together with the construction of the fabric foundation. Of course, rigid joining of the precast product to the fabric foundation may also be considered.

また、コンクリート支持体と隅柱との面間間隙が数十ミリメートルであり、該間隙に粘弾性材又は振動吸収材を介設している。好適にはゴム弾性を有する樹脂素材を、間隙の長手方向に棒状設置し、かつ、面周方向には離隔配置するものである。   Further, the inter-surface gap between the concrete support and the corner column is several tens of millimeters, and a viscoelastic material or a vibration absorbing material is interposed in the gap. Preferably, a resin material having rubber elasticity is installed in a bar shape in the longitudinal direction of the gap and spaced apart in the surface circumferential direction.

本発明の一実施例について添付図面を参照して以下説明する。   An embodiment of the present invention will be described below with reference to the accompanying drawings.

図1は、実施例建築物の平面図である。   FIG. 1 is a plan view of an example building.

図2は、実施例建築物のコーナーサポート平面詳細図である。   FIG. 2 is a detailed plan view of a corner support of the example building.

図3は、実施例建築物の正面視立面図である。   FIG. 3 is a front elevation view of the example building.

図4は、実施例建築物の側面視立面図である。   FIG. 4 is a side elevational view of the example building.

図示するように、実施例建築物は、振動抑制構造を有するプレハブ化された軽量鉄骨造建築物であって、出隅部(1)にコンクリート製のコーナーサポート(2)を設けたものである。   As shown in the figure, the example building is a prefabricated lightweight steel structure having a vibration suppressing structure, and is provided with a corner support (2) made of concrete at the protruding corner (1). .

コーナーサポート2の構築は、布基礎3に立設した隅柱1に対して、断面視L形のコンクリート支持体2を布基礎3と一体化又は剛接合して立ち上げ添設する。そして、コンクリート支持体2のアングル内面と隅柱1の対向外面との面間にわずかな間隙5を設ける。〔図2〕   In the construction of the corner support 2, a concrete support 2 having a sectional view L-shaped is integrated with or rigidly joined to the corner column 1 standing on the cloth foundation 3 and attached thereto. A slight gap 5 is provided between the angle inner surface of the concrete support 2 and the opposing outer surface of the corner post 1. [Figure 2]

ここで、コンクリート支持体2は現場打設の鉄筋コンクリート(RC)であり、隅柱1の少なくとも1/2の高さを有するものとするのが好ましい。   Here, the concrete support 2 is reinforced concrete (RC) cast in the field, and preferably has a height at least half that of the corner post 1.

また、コンクリート支持体2と隅柱1との面間間隙5を数十ミリメートルとし、該間隙5に粘弾性材又は振動吸収材4を介設している。この場合、粘弾性材又は振動吸収材4はゴム弾性を有する樹脂素材であり、間隙5の長手方向に棒状設置され、かつ、面周方向には離隔配置される。   Further, the inter-surface gap 5 between the concrete support 2 and the corner column 1 is set to several tens of millimeters, and a viscoelastic material or a vibration absorbing material 4 is interposed in the gap 5. In this case, the viscoelastic material or the vibration absorbing material 4 is a resin material having rubber elasticity, and is disposed in a rod shape in the longitudinal direction of the gap 5 and is spaced apart in the surface circumferential direction.

この構成によると、施工容易でプレハブ構造の短所である「振れ」の問題を解消できる。   According to this configuration, it is easy to construct and can solve the problem of “runout” which is a disadvantage of the prefabricated structure.

本発明は、プレハブ化された軽量鉄骨造建築物に振動抑制構造を付加する新たな施工方法を開発した点で有用であり、産業上の利用価値が高いものである。   INDUSTRIAL APPLICABILITY The present invention is useful in that a new construction method for adding a vibration suppression structure to a prefabricated lightweight steel structure is developed and has high industrial utility value.
