【考案の詳細な説明】
（産業上の利用分野）
この考案は鉄骨梁をコンクリート製のスチフナ
ーで補強した構造の補強鉄骨梁構造に関するもの
である。[Detailed description of the invention] (Field of industrial application) This invention relates to a reinforced steel beam structure in which a steel beam is reinforced with concrete stiffeners.
（考案が解決しようとする問題点）
鉄骨梁を補強するスチフナーにはこれまでは鋼
板が使用されているが、この構造は鋼板の端面を
溶接するものであるため必然的に施工に時間を要
し、工期が長びくことに加え、コスト高である等
の難点を抱えている。(Problem that the invention aims to solve) Until now, steel plates have been used for stiffeners that reinforce steel beams, but since this structure involves welding the ends of the steel plates, it inevitably takes time to construct. However, in addition to the long construction period, there are also disadvantages such as high costs.
この考案はこうした鉄骨梁の補強に伴う難点を
軽減する目的からなされたもので、コンクリート
製のスチフナーを使用することによりこれを解決
しようとするものである。 This idea was made to alleviate the difficulties associated with reinforcing steel beams, and attempts to solve this problem by using concrete stiffeners.
（問題点を解決するための手段）
本考案ではスチフナーをプレキヤストコンクリ
ートで製作し、これを鉄骨梁のウエブにボルトで
接合することにより使用鋼材量の低減、施工の簡
略化を図る。(Means for solving the problem) In this invention, the stiffener is made of precast concrete and is connected to the web of the steel beam with bolts, thereby reducing the amount of steel used and simplifying the construction.
スチフナーはフルウエブ型の鉄骨梁の上下フラ
ンジ間に嵌合する形状であり、これを複数個間隔
をおいて鉄骨梁のウエブを挟むようにこの両面に
突き合わせる。そしてウエブを介して対向したス
チフナーにボルトを挿通してこれをウエブに接合
する。 The stiffeners are shaped to fit between the upper and lower flanges of a full-web type steel beam, and a plurality of stiffeners are placed at intervals and abutted against both sides of the steel beam so as to sandwich the web of the steel beam. Then, bolts are inserted into the stiffeners facing each other via the web to join them to the web.
（実施例）
以下本考案を実施例を示す図面に基づいて説明
する。(Example) The present invention will be described below based on drawings showing examples.
この考案はフルウエブ型の鉄骨梁１のウエブ１
ａにプレキヤストコンクリート製のスチフナー２
をボルト３で接合し、鉄骨梁１のウエブ１ａを補
強した構造としたものである。 This idea is based on the web 1 of a full web type steel beam 1.
Stiffener 2 made of precast concrete in a
are joined with bolts 3, and the web 1a of the steel beam 1 is reinforced.
スチフナー２は第１図−のようにウエブ１ａ
の両面に対向してボルト３により接合され、の
ように間隔をおいて複数個取り付けられる。この
ためウエブ１ａ及びスチフナー２には予めボルト
挿通孔が設けられる。 The stiffener 2 is attached to the web 1a as shown in Figure 1.
They are joined by bolts 3 facing each other on both sides, and a plurality of them are attached at intervals as shown in FIG. For this purpose, bolt insertion holes are provided in advance in the web 1a and the stiffener 2.
第２図に示す実施例はスチフナー２に埋設した鉄
筋４をスラブ５に埋め込んで鉄骨梁１を拘束し、
この横座屈を防止する構造としたものである。In the embodiment shown in FIG. 2, reinforcing bars 4 embedded in the stiffener 2 are embedded in the slab 5 to restrain the steel beam 1,
The structure is designed to prevent this lateral buckling.
第３図に示す実施例はスチフナー２に突起２ａ
を形成してこれを小梁受として利用し、この突起
２ａ上に小梁６を載置した場合である。 The embodiment shown in FIG. 3 has a projection 2a on the stiffener 2.
This is a case where a small beam 6 is placed on this protrusion 2a by forming a small beam and using this as a small beam support.
なおスチフナー２は鉄筋コンクリートの他にフア
イバーコンクリート、グラスフアイバーコンクリ
ートで製作してもよい。Note that the stiffener 2 may be made of fiber concrete or glass fiber concrete in addition to reinforced concrete.
（考案の効果）
この考案は以上の通りスチフナーを鋼材に代え
てコンクリートで製作し、ウエブへの接合をボル
トで行う構造であるため鋼材量及びその溶接量が
低減され、その結果経費の節減、工期の短縮化を
図ることができる。(Effects of the invention) As described above, this invention has a structure in which the stiffener is made of concrete instead of steel and is connected to the web with bolts, so the amount of steel and welding is reduced, resulting in cost savings. It is possible to shorten the construction period.
