加熱工法などが知られている。"Conventional technology and problems to be solved by the invention" As a conventional breaking device of this type, an expanding wedge is interposed in the center gap of a two-piece rod with the center divided vertically, and this two-piece rod is converted to concrete. Dalda construction method, which is inserted tightly into the perforations provided, pushes the expansion wedge in this state and expands the two-part rod outward, destroys the material, and expands the expanding agent into the voids provided in the concrete. There is known an expanding agent method that breaks by filling and expanding, or an energizing heating method that breaks down due to the thermal expansion of the reinforcing bar and the weakening of the surrounding concrete due to the thermal expansion of the reinforcing bar and the heat caused by heating. I have.
しかしながら、ダルダ工法では壊れたコンクリートに
より器具が損傷されることがあり、また同時に多数設置
して破壊することが困難で、しかも破壊速度を調節でき
ないという問題がある。However, in the Daruda method, there is a problem that tools may be damaged by broken concrete, it is difficult to install a large number of pieces at the same time, and the breaking rate cannot be adjusted.
また、膨張剤工法では破壊に要する時間が長く、また
充填剤厚さが薄いと破壊効果が期待できず、しかも破壊
速度を調節できないないなどの問題がある。In addition, the expanding agent method has a problem that the time required for breaking is long, and if the thickness of the filler is small, the breaking effect cannot be expected and the breaking speed cannot be adjusted.
さらに、通電加熱工法では、鉄筋が内蔵されていて、
通電電極を鉄筋の両端に接続可能であることが条件とな
るため、無筋コンクリートや石材などを破壊することが
できないという問題がある。Furthermore, in the electric heating method, rebar is built in,
Since it is a condition that the current-carrying electrodes can be connected to both ends of the reinforcing bar, there is a problem that it is not possible to break unreinforced concrete or stone.
「問題点を解決するための手段」 この発明は、前記従来の問題点を解決するために、軸
心部に耐熱性、非圧縮性を有する高強度材料を充填して

ある。"Means for Solving the Problems" The present invention provides a heat-expandable metal having a shaft center filled with a high-strength material having heat resistance and incompressibility in order to solve the conventional problems. The present invention proposes a concrete breaking device in which a power circuit is connected to the front and rear ends of a rod.
「作用」 破壊対象のコンクリートに予めロッド挿入用の孔を削
孔し、この削孔内にロッドを密に挿填し、電源回路に通
電してロッドを加熱することにより、ロッドを膨張させ
て周辺のコンクリートを破壊する。"Action" A hole for rod insertion is drilled in advance in the concrete to be destroyed, the rod is densely inserted into this hole, and the power is supplied to the power supply circuit to heat the rod, thereby expanding the rod. Destroy surrounding concrete.
「実施例」 ロッド１は、熱膨張性を有する金属により断面円形等
の中空に成形され、その軸心の中空部には耐熱性、非圧
縮性に優れた強化セラミックス等の高強度材料で成形さ
れた心棒２が挿填されている。[Example] The rod 1 is formed into a hollow having a circular cross section or the like by a metal having a thermal expansion property, and a hollow portion of the shaft center is formed of a high strength material such as a reinforced ceramic having excellent heat resistance and incompressibility. The inserted mandrel 2 is inserted.

ング５に電源回路の電線３の他端の端子６が接続されて
いる。A part of the electric wire of the power supply circuit 3 is wired inside the mandrel 2, a terminal 4 at one end thereof is connected to the tip of the rod 1, and an electrode ring 5 slidably fitted to the rear end of the rod 1. Is connected to a terminal 6 at the other end of the electric wire 3 of the power supply circuit.
以上のロッド１を用いてコンクリート等を破壊する際
には、まず破壊対象７に予めロッド挿入用の孔８を削孔
し、この削孔８内にロッド１を密に挿填する。When breaking concrete or the like using the rod 1 described above, first, a hole 8 for inserting a rod is drilled in advance in the breaking target 7, and the rod 1 is densely inserted into the drilled hole 8.
このとき、孔８が大きくその孔壁とロッド１との間に
隙間を生ずる場合には、孔３内に予めセメントミルク等
の充填固結剤を入れておき、ロッド１の押し込みと同時
に隙間を充填する。At this time, if the hole 8 is large and a gap is formed between the hole wall and the rod 1, a filling binder such as cement milk is put in the hole 3 in advance, and the gap is simultaneously formed when the rod 1 is pushed. Fill.
この状態で、電源回路３に通電してロッド１を加熱す
ることにより、ロッド１を径方向に膨張させてその周辺
のコンクリートを破壊する。In this state, the power supply circuit 3 is energized to heat the rod 1, thereby expanding the rod 1 in the radial direction and destroying the surrounding concrete.
なお、電極リング５をスライド調節することにより、
ロッド１の挿入範囲（膨張範囲）を適宜調節することが
できる。In addition, by adjusting the slide of the electrode ring 5,
The insertion range (expansion range) of the rod 1 can be appropriately adjusted.
「発明の効果」 以上の通りこの考案によれば、破壊器具が堅牢かつシ
