Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、建物その他の構造物の床や梁を支承する柱部
材としての接合用鋼管コンクリート柱に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a steel pipe concrete column for joining as a column member for supporting floors and beams of buildings and other structures.
鋼管を建物の柱として利用する場合は、中空のままでは
軸圧が大きくなったり、曲げ応力が大きくなったりする
と局部座屈を起すおそれがあるので、内部にコンクリー
トを充填することが行われる。When a steel pipe is used as a pillar of a building, if it is hollow, a large axial pressure or a large bending stress may cause local buckling, so that the interior is filled with concrete.
この内部充填コンクリート12には、軸圧の一部を負担さ
せるという考え方もある。There is also an idea that the internal filling concrete 12 bears a part of the axial pressure.
しかし、鋼管内部のコンクリートは収縮性等があるため
に外側の鋼管に対して十分な付着力を期待することがで
きない。However, the concrete inside the steel pipe cannot be expected to have sufficient adhesive force to the outer steel pipe because the concrete has shrinkage properties.
例えば、前記柱の梁や床への取付けは鋼管にブラケット
を溶接しこれを介して行なうが、該梁や床から伝達され
る荷重は鋼管部分に集中して伝達され、鋼管は少し縮
む。そして前記のごとく内部のコンクリートは付着力が
少ないので、鋼管から剥離するような状態となり、荷重
はコンクリートには充分伝達されないことになる。For example, the pillar is attached to the beam or floor by welding a bracket to the steel pipe and via this, but the load transmitted from the beam or floor is concentrated on the steel pipe portion and the steel pipe shrinks slightly. Since the concrete inside has a small adhesive force as described above, the concrete is separated from the steel pipe, and the load is not sufficiently transmitted to the concrete.
従って、内部のコンクリートは鋼管の座屈防止には役立
つが、強度的には活用されないことが多い。Therefore, the concrete inside helps prevent buckling of the steel pipe, but it is often not utilized in terms of strength.
本考案の目的は前記従来例の不都合を解消し、外部鋼管
と内部充填コンクリートの密着性を確実に高め、構造上
信頼性を向上させることができ、１承部材として適した
鋼管コンクリート柱を提供することにある。The object of the present invention is to eliminate the disadvantages of the conventional example, to reliably improve the adhesion between the outer steel pipe and the inner filling concrete, and to improve the structural reliability, and to provide a steel pipe concrete column suitable as a single bearing member. To do.
本考案は前記目的を達成するため、鋼管内部にコンクリ
ートを充填してなる柱において、この鋼管の一部を下方
に広がるテーパー部分として形成し、該テーパー部分に
梁や床への接合用フランジを突設したことを要旨とする
ものである。In order to achieve the above-mentioned object, the present invention forms a part of the steel pipe as a tapered portion that spreads downward in a column formed by filling the inside of the steel pipe with a flange for joining a beam or a floor to the tapered portion. The gist of the project is that it is installed.
本考案によれば、梁や床等からの荷重は鋼管部分に集中
し、これが収縮するようなかたちで伝達される。そし
て、フランジを介してテーパー部分に比重がかかるが、
このテーパー部分は内部のコンクリートにせり持ちのよ
うに軸力の一部を伝達されるので強度があり、全体とし
て支承部材に適する。According to the present invention, the load from the beam, floor or the like is concentrated on the steel pipe portion and is transmitted in such a manner that it contracts. And the specific gravity is applied to the tapered part through the flange,
This tapered portion has a strength because it transmits a part of the axial force to the concrete inside like a bank, and is suitable as a supporting member as a whole.
以下、図面について本考案の実施例を詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
第１図は本考案の鋼管コンクリート柱の第１実施例を示
す側面図、第２図は同上取付状態を示す正面図で、図中
１は鋼管、２は該鋼管１の内部に充填するコンクリート
を示し、全体として柱３を形成する。FIG. 1 is a side view showing a first embodiment of a steel pipe concrete column of the present invention, and FIG. 2 is a front view showing a mounting state of the same, in which 1 is a steel pipe and 2 is concrete for filling the inside of the steel pipe 1. The pillar 3 is formed as a whole.
この鋼管１はその一部を下方に広がるテーパー部分１ａ
として形成した。This steel pipe 1 has a taper portion 1a that partially expands downward.
Formed as.
該テーパー部分１ａは鋼管１の上端とし、この部分にフ
ランジ６を突設して梁４や床５を接合する。The tapered portion 1a is the upper end of the steel pipe 1, and a flange 6 is projected on this portion to join the beam 4 and the floor 5.
このようにして、柱３はフランジ６を介して、床や梁に
接続し、これら床や梁から伝達される荷重は、まず鋼管
１に集中して伝わり、鋼管１は長さ方向に収縮しようと
する。そして、先に述べたように、鋼管１のテーパー部
分１ａは内部のコンクリート２にはせり持ちのように軸
力の一部が伝達される。In this way, the column 3 is connected to the floor or the beam via the flange 6, and the load transmitted from the floor or the beam is first concentrated and transmitted to the steel pipe 1 so that the steel pipe 1 tends to contract in the length direction. . Then, as described above, the taper portion 1a of the steel pipe 1 transmits a part of the axial force to the concrete 2 inside like a slant.
なお、コンクリート２が鋼管１の座屈防止に役立つこと
は言うまでもない。Needless to say, the concrete 2 helps prevent buckling of the steel pipe 1.
さらに、他の変形例として、第３図に示すようにテーパ
ー部分１ａは鋼管１の途中に形成してもよく、また第４
図に示すようにさらにテーパー部分１ａの直下を下方に
すぼまる逆テーパー部分１ｂとしてもよい。Further, as another modification, the tapered portion 1a may be formed in the middle of the steel pipe 1 as shown in FIG.
As shown in the figure, a portion immediately below the tapered portion 1a may be an inverted tapered portion 1b which is narrowed downward.
なお、第４図のように、柱３を２層分のものとすれば、
梁４や床５をフランジ６を介して接合すると、第５図に
示すごときものとなる。As shown in FIG. 4, if the pillar 3 has two layers,
When the beam 4 and the floor 5 are joined via the flange 6, the structure as shown in FIG. 5 is obtained.
このように鋼管１に部分的にテーパー部分１ａを形成
し、鋼管１は全体に連続しているので、このテーパー部
分１ａで内部のコンクリートを拘束し、前記第１実施例
と同様の作用が得られる。In this way, since the tapered portion 1a is partially formed on the steel pipe 1 and the entire steel pipe 1 is continuous, the inner concrete is restrained by the tapered portion 1a, and the same operation as that of the first embodiment can be obtained. To be
以上述べたように本考案の接合用鋼管コンクリート柱
は、鋼管内部にコンクリートを充填してなる柱におい
て、鋼管とコンクリートの密着性を高め、コンクリート
部分に従来の鋼管の局部座屈の防止という働きの他に、
軸力の一部を負担させることができるのでその分だけ経
済的な構造物とすることができる。As described above, the steel pipe concrete column for connection of the present invention is a column in which the inside of the steel pipe is filled with concrete, which enhances the adhesion between the steel pipe and the concrete and prevents the concrete portion from locally buckling the conventional steel pipe. Others,
Since it is possible to bear a part of the axial force, the structure can be made economical accordingly.
そして、軸圧の大きくなる高層建物など多くの分野に活
用できるものである。And it can be used in many fields such as high-rise buildings where the axial pressure becomes large.
また、床や梁に接合するフランジをテーパー部分で支承
するが、このテーパー部分は、内部のコンクリートにせ
り持ちのように軸力の一部を伝達されるので強度があ
り、全体として支承部材に適したものである。In addition, the flange that joins the floor and the beam is supported by the taper part, but this taper part is strong because it transmits a part of the axial force like the internal concrete, which is suitable for the support member. It is a thing.
