Description

本発明は、コラム(角形鋼管)切梁の端部が腹起しに接合された端部切梁と火打梁に切梁火打接続ピースを介して接続されてなる切梁火打接続構造および切梁火打接続ピースに関し、コラム(角形鋼管)切梁の端部を腹起しに接合された端部切梁と火打梁に切梁火打接続ピースを介して容易にかつ強固に接合できるようにしたものである。   The present invention relates to an end beam having a column (square steel pipe) end beam joined in an upright manner, and a cut beam fired connection structure and a cut beam connected to a fire beam through a cut beam connection piece. Concerning fire hitting connection piece, the end beam of the column (square steel pipe) cutting beam is joined to the end beam and the hitting beam easily and firmly through the shot beam hitting connection piece. It is.

山留め工事で使用される腹起しや切梁などの山留め材には、主としてＨ形鋼が使用され、状況によりコラム(角形鋼管)切梁も使用される。   H-beams are mainly used for the retaining members such as the uprights and the beams used in the retaining work, and column (square steel pipe) beams are also used depending on the situation.

Ｈ形鋼は、曲げに対して強軸と弱軸があり、曲げ方向によって曲げ強度に違いがあるため、補強材として火打梁や棚杭、さらには水平繋ぎ材などが併せて使用され、通常、図３に図示するように山留め壁を支える腹起し５と切梁１との接合部に火打梁3,3が設置され、各火打梁3,3の両端は切梁１と腹起し５にそれぞれボルト接合される。   H-shaped steel has a strong axis and a weak axis for bending, and there is a difference in bending strength depending on the bending direction. Therefore, fire beams, shelf piles, and horizontal connecting materials are also used as reinforcing materials. As shown in FIG. 3, fire beams 3 and 3 are installed at the joint between the uplift 5 supporting the retaining wall and the cut beam 1, and both ends of each fire beam 3 and 3 are raised up with the cut beam 1. To each bolt.

また特に、山留め壁を支える腹起し５をより長い火打スパンＬで支持する場合は、図４に図示するように２本の切梁1,1を腹起し５の材軸方向に間隔をおいて設置し、その外側に火打梁3,3を設置することも行われる。   Further, in particular, when the uplift 5 that supports the retaining wall is supported by a longer firing span L, as shown in FIG. It is also possible to install fire struts 3 and 3 outside thereof.

一方、コラム(角形鋼管)切梁は、強軸・弱軸といった概念がないため、火打梁などの補強材で補強することはないが、通常、コラム切梁の端部は、図５に図示するように平面に視て三角形状に形成された火打ピース14を介して腹起し５に接合される。   On the other hand, a column (square steel pipe) beam has no concept of a strong axis or a weak axis, so it is not reinforced with a reinforcing material such as a fired beam, but the end of the column beam is usually shown in FIG. In this way, it is joined to the abdomen 5 through the striking piece 14 formed in a triangular shape when seen in a plan view.

特開平04-068116号公報Japanese Patent Laid-Open No. 04-068116 特開2002-081084号公報JP 2002-081084 A 特開2015-175226号公報JP-A-2015-175226

しかし、Ｈ形鋼は、曲げに対して強軸と弱軸があり、曲げ方向によって曲げ強度に違いがあるため、設置に際しては方向に注意する必要があり、また、部材どうしの接合に多くの接合ボルトを必要とするため、その締付けに多大な労力を必要とする等の課題がある。   However, because H-shaped steel has a strong axis and a weak axis with respect to bending and there is a difference in bending strength depending on the bending direction, it is necessary to pay attention to the direction during installation, and many members are joined to each other. Since a joining bolt is required, there are problems such as requiring a great deal of labor for tightening.

一方、コラム切梁は、火打スパンＬを充分に確保できないことから、コラム切梁の持つ利点を充分に発揮できないという課題があった。また、必要により火打梁による補強も行われるが、Ｈ形鋼のように接合ボルトを自由に使用できないことから、余り実施されていない。   On the other hand, the column beam has a problem in that the advantage of the column beam cannot be fully exhibited because the firing span L cannot be sufficiently secured. In addition, reinforcement with a fire beam is performed if necessary, but it is not carried out so much because the joining bolt cannot be freely used like H-shaped steel.

本発明は、以上の課題を解決するためになされたもので、コラム(角形鋼管)切梁の端部を腹起しに接合された端部切梁と火打梁に切梁火打接続ピースを介して容易にかつ強固に接合できるようにした切梁火打接続構造および切梁火打接続ピースを提供することを目的とするものである。   The present invention has been made in order to solve the above-described problems.The end beam of the column (square steel pipe) beam is joined to the edge beam and the fire beam, and the beam is connected to the fire beam via the beam-fired connection piece. It is an object of the present invention to provide a beam-fired connection structure and a beam-fired connection piece that can be joined easily and firmly.
