  • the pair of crushing bodies 5, 5 abut with the RC object to be crushed (pillar, beam or the like) before the protruding portions 2e, 2e do when the pair of movable jaw main bodies 2, 2 are closed, as shown in Fig. 12A and Fig. 12B.
  • the cutting blades 5a on the pointy ends of the pair of crushing bodies 5, 5 operate to cut the RC object to be crushed in half, and at the same time perform pressing and crushing along the longitudinal direction by means of the protruding portions 2e, 2e to crush the RC object into pieces.
  • the pair of crushing bodies 5, 5 can perform this crushing work without causing reaction force for pushing the RC object to be crushed (pillar, beam or the like) out.
  • the pressing direction of the pair of crushing bodies 5, 5 is configured such that breaking load is added, in a substantially horizontal direction in Fig. 7, to the steel s of a wide flange beam or flat steel bar of a pillar body of the SRC object to be crushed S or a RC object to be crushed (pillar, beam or the like), and such that nearly no component force for pushing out to the front (force for pushing out downward in the page space in Fig. 7) is generated.
  • the present invention can quickly and safely crush the SRC object to be crushed S (pillar, beam or the like) of SRC buildings or the like that will increase in our country in the future. Moreover, the present invention can provide a crush field which is extremely useful in large numbers of RC objects to be crushed (pillar, beam and the like) that exist today, and can be applied in a wide application range and provided as a leader in crushing concrete in the future.
