This is to deform and damage the exposed steel s such as H-beam or flat steel of the crushed material S (column or beam), and at the same time to crush the concrete existing inside the steel s such as H-beam or flat steel. .
- the crushed body 5 has a force in which the shape of the abacus is substantially halved.
- a crushed body in the shape of a semi-disc with a sharpened peripheral edge is also included. Further, it may have a straight blade shape.
- the straight blade has a cross-sectional shape as shown in FIG. 5 and has the same cross-section and a predetermined length.
- the linear portion of the blade portion to be crushed, such as the tip or peripheral edge of the crushed body 5, is referred to as a crushing blade line 5a, and the direction of the crushing blade line 5a is oriented in the same direction as the longitudinal direction of the movable jaw main body 2. Is formed.
- crushed body 5 is a cemented carbide or tool steel. In particular, a stronger cemented carbide may be provided only at the crushing blade line 5a.

- the crushing blade line 5a which is the tip of the crushed bodies 5,5
- the crushing blade line 5a is turned into a long H-shaped steel. Pressing from both sides so as to be perpendicular to the longitudinal direction (Y direction in FIG. 4) of the steel plate s or flat steel, etc. .
- the longitudinal direction of the long steel frame s is such that the longitudinal direction of the H-shaped steel plate or the flat bar of the long steel frame s is perpendicular (including the direction substantially perpendicular).
- deformation starts as shown in Fig. 5A by squeezing the concentrated load on the plate or on the side near the side edge of the flat steel.
- the concrete filled with the H-shaped steel plate of the steel frame s or the inner surface of the flat steel is buckled only on the back surface of the H-shaped steel plate of the steel s or the deformed portion of the flat steel. Is done.
- the cause of the deformation is the pressing structure of the crushed bodies 5 and 5. That is, as shown in FIG. 3, the two shaft supports 3, 3 are configured to be spaced apart from each other with a predetermined distance L, whereby the pressing direction of the crushed bodies 5, 5 is controlled by the SRC. Pressing and breaking loads are applied in a substantially horizontal direction to the steel frame s such as the H-shaped steel or flat steel of the columnar body of the material S to be crushed. (Extrusion force) is almost eliminated, and a component force such as pull-in may be generated. However, the most efficient crushing can be performed on a general SRC crushed object S column.
- the predetermined distance L is about 30 cm to about 70 cm, and the distance M between steel frames s such as H-section steel or flat steel of the SRC column (specifically, about 40 cm to about 100 cm). ).

- the small interval ⁇ is often about 5 cm to about 10 cm.
- an intermediate pressing portion 2 d is expanded at an intermediate position on the work surface side of the movable jaw main body 2. It is formed.
- the tip of the intermediate pressing portion 2d has a V-shape, and the edge of the tip is configured to be orthogonal to the plane of FIG.
- the tip of the intermediate pressing portion 2d crushes concrete.
- it also plays a role in supporting RC crushed objects (posts, beams, etc.).
- the protruding portions 2e, 2e are provided so as to be located closer to the distal ends than the crushed bodies 5, 5 when the movable jaw bodies 2, 2 are closed.
- a slab such as a floor or a ceiling is crushed by the protruding portions 2e, 2e by a protruding operation, and the movable jaw bodies 2, 2 are made movable.
- a relatively thin RC crushed object a column or a beam or the like
- the crushed bodies 5 and 5 act to cut in half with the cutting edge line 5a at the tip, and press and crush along the longitudinal direction at the tip edge line of both projections 2e and 2e. They are crushed into pieces. Needless to say, the crushing work can be performed while hardly applying a reaction force such as pushing out the RC crushed object (a column or a beam) to the outside by the crushing bodies 5 and 5.
- the pressing direction of the two crushed bodies 5 and 5 is such that the column of the SRC crushed material S is made of steel s such as H-shaped steel or flat steel or RC crushed material ( As shown in Fig. 7, a pressure breaking load is applied to the column or beam, etc. in a substantially horizontal direction, and the component to be extruded before (the force to push down in the paper of Fig. 7) is almost eliminated.
- the reaction force that pushes the general SRC crushed object S column or RC crushed object (column or beam, etc.) to the outside can be hardly applied, and Fig. 13A-Fig. 13C and Fig. 14A
- FIG. 14B there is an IJ point that can avoid a defect that a column or the like falls down or a part of the column falls outside during crushing.
