この発明は周縁部を中空スラブとした鉄筋コンクリート
スラブに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reinforced concrete slab with a hollow peripheral edge.
鉄筋コンクリートスラブ周辺の梁の固定度が太きいと端
部応力は中央部応力に比較して倍近くになることがあり
、通常の設計ではスラブ端部は配筋が密となる。また荷
重が太きいとスラブ厚さを大きくするが、これは建物全
体の重量を増すことになり好ましくない。さらにスパン
９ｍ前後の鉄筋コンクリートスラブは全面中空スラブよ
シ、従来構造のスラブを併用した方が経済的となる。If the beams around a reinforced concrete slab are rigidly fixed, the stress at the ends can be nearly double the stress at the center, and in normal designs, reinforcement is densely arranged at the ends of the slab. Also, if the load is heavy, the thickness of the slab will be increased, which is undesirable because it increases the weight of the entire building. Furthermore, it is more economical to use a reinforced concrete slab with a span of around 9m, instead of a completely hollow slab, or a slab with a conventional structure.
この発明は前記事情を総合的に勘案した結果開発したも
ので以下その詳細を図示した実施例によって説明する。This invention was developed as a result of comprehensive consideration of the above circumstances, and details thereof will be explained below with reference to illustrated embodiments.
図においてスラブ１は柱２上の梁５でその四辺を支持さ
れた鉄筋コンクＩＪ −ト構造である。In the figure, a slab 1 is a reinforced concrete IJ-concrete structure supported on its four sides by beams 5 on columns 2.
中央部Ａのスラブ厚は通常のスラブと同様に小さく形成
し、周縁部Ｂのスラブ厚を太きく形成し、スラブ厚の大
きい周縁部に多数の中空管４を埋設して中空スラブとし
である。The thickness of the slab in the center part A is made small like a normal slab, and the thickness of the slab in the peripheral part B is made thicker, and a large number of hollow tubes 4 are buried in the peripheral part where the slab thickness is large to form a hollow slab. be.
スラブの中央部大は第３図〜７図に示すように略菱形に
形成するかあるいは第８図、第９図に示すように方形に
形成する。また中空管４の配置状態は第５〜９図に示す
通シである。なお柱頭部Ｃのスラブには中空管を埋設し
ないで剛性を高めである。The central portion of the slab is formed into a substantially diamond shape as shown in FIGS. 3 to 7, or square as shown in FIGS. 8 and 9. The arrangement of the hollow tubes 4 is as shown in FIGS. 5 to 9. Note that no hollow tube is buried in the slab of the column head C to increase rigidity.
この発明は以上の構成からなり、端部応力の大きいスラ
ブ周辺のみを中空スラブとするこ、とによシ、荷重に対
して合理的でかつ床自重を増大させることなく経済的な
構造を提供できる。This invention consists of the above-mentioned structure, and by making only the periphery of the slab with large end stress a hollow slab, it provides an economical structure that is rational for the load and does not increase the floor's own weight. can.
また中壁スラブ部は大梁の梁成と略同等となシ従来のハ
ンチ部、柱頭スラブ部と同様の作用をなしてスラブ荷重
を柱に伝達する。In addition, the middle wall slab section is approximately the same as the beam structure of the girder, and functions in the same way as the conventional haunch section and column head slab section, transmitting the slab load to the column.
