この発明は鉄筋または鉄骨入りコンクリート材を破壊す
る方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for destroying reinforcing steel or steel-filled concrete.
従来、鉄筋または鉄骨入りコンクリート材は機械的破壊
装置（プレス破壊または衝撃破壊）を使用し、プレスの
圧縮力または破壊球の衝撃力で破壊している。Conventionally, reinforcing bars or concrete materials with steel frames are destroyed using a mechanical breaking device (press breaking or impact breaking) using the compressive force of a press or the impact force of a breaking ball.
従来の機械的破壊装置では強大な破壊力を必要とするこ
とから、機械装置の大形化による高価な設備および強大
な破壊力による破壊音で騒音公害等の欠点があって、あ
まり実用化されていない。Conventional mechanical destruction devices require a large amount of destructive force, so they have disadvantages such as expensive equipment due to the large size of the device and noise pollution caused by the destruction noise caused by the large amount of destructive force, so they have not been put into practical use much. Not yet.
この発明は上記のような従来のものの欠点を除去するた
めになされたもので、コンクリート材内の鉄筋、鉄骨を
誘導加熱することにより、鉄筋、鉄骨の熱膨張力とコン
クリートの熱劣化により、破壊することが出来る破壊方
法を提供することを目的としている。This invention was made in order to eliminate the drawbacks of the conventional methods as described above, and by induction heating the reinforcing bars and steel frames in the concrete material, the thermal expansion force of the reinforcing bars and steel frames and the thermal deterioration of the concrete cause destruction. The purpose is to provide a method of destruction that can be done.
以下この発明の方法を図について説明する。The method of the present invention will be explained below with reference to the drawings.

電力を供給するための電源である。In the figure, (1) is a concrete material containing reinforcing bars and steel frames, such as concrete utility poles and concrete piles, which consists of concrete (11) and reinforcing bars and steel frames (12) buried therein, and (12a) indicates reinforcing bars, ( 12b) is an iron ring. (2) is an induction heating coil installed around the outer periphery of the concrete material (1), and (3) is a power source for supplying electric power to the induction heating coil (2).

発生する。When power is supplied from the power source (3) to the induction heating coil (2), the reinforcing bars and steel frames (12) inside the concrete material (1) are heated by the electromagnetic induction phenomenon, and the heated reinforcing bars,
Cracks occur in the concrete (11) due to the thermal expansion force of the steel frame (12) and thermal deterioration of the concrete (11) due to thermal effects.
