In the dismantling work, the crushing work is performed substantially simultaneously with the reinforced concrete part and the concrete part. It relates to a crusher that can be made very efficient.

[0002]

2. Description of the Related Art In recent years, as a device for dismantling and crushing a reinforced concrete structure (building or the like), a fixed jaw and a movable jaw are provided which can be freely attached to the tip of a working boom of a working vehicle. Many of the movable jaws are used to crush reinforced concrete walls, columns, and the like, so that extremely efficient crushing work can be performed.

[0003]

However, as for the structure made of reinforced concrete, the durability, seismic resistance and the like are further required, and the reinforcing steel in the concrete is thicker and more complicatedly formed and formed as required. Since the reinforcing bars synergistically increase the strength of the structure, it is becoming difficult to crush the structure with a conventional crusher.

[0004] Further, when crushing a concrete lump and then moving a small lump or a reinforcing bar to another place, a vehicle such as a shovel or a bulldozer is required. However, when these vehicles cannot be prepared immediately, or When only a small amount of concrete needs to be moved, it is unexpectedly troublesome to grasp concrete small blocks or rebars with the fixed jaw and movable jaw of the crusher, and it is said that only concrete blocks of a certain size can be grasped. There were inconveniences.

[0005]

The inventor of the present invention has made intensive studies to solve the above-mentioned problems, and as a result, has found that the present invention relates to a fixed jaw main body formed on an outer casing of a crusher and a method for supporting the fixed jaw main body. A movable jaw body is provided on the outer housing of the crusher so as to be openable and closable, a semicircular abacus-shaped vertically split large blade is formed near the tip of the movable jaw body, and an abacus bead is provided at the foremost point of the movable jaw body. By forming a horizontally-divided large blade in the shape, by making the vertically-divided large blade and the horizontally-divided large blade close to each other, and the horizontally-divided large blade being a crusher substantially orthogonal to the vertically-divided large blade, it is made of reinforced concrete. It is possible to cut and crush a reinforcing bar portion and a concrete portion of a wall, a column, and the like constituting a structure substantially simultaneously, thereby solving the above-mentioned problem.
