Description

  The present invention relates to a dismantling apparatus for disassembling, for example, a concrete skeleton constructing a building.

  When rebuilding a concrete structure such as an aged building, it is necessary to dismantle the concrete frame that is constructing the concrete structure. In a large-scale dismantling site, a mobile crusher equipped with a jaw crusher or an impact crusher may be used on a traveling carriage.

  However, such mobile crushers are expensive and may not be profitable depending on the scale of the dismantling site. In such a case, for example, a crushing process of the concrete frame is performed using a nibler or the like to which crushing teeth are attached.

  However, when a nibler is used for dismantling a concrete frame, it is necessary to supply and discharge hydraulic oil to and from an operating cylinder for operating the nibler. That is, since it is necessary to add hydraulic piping, the cost increases. In addition, the nibbler is generally difficult to operate because the opening / closing operation is a pedal operation, and the opening / closing speed is slow.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a dismantling apparatus that can increase the efficiency of dismantling work with a simple configuration.

  The disassembling apparatus of the present invention includes a frame, a cutting blade, a pressing member, and an advance / retreat mechanism. The frame is formed with an opening for inserting a dismantling object having a first surface and a second surface on the back side. The cutting blade is provided at a position facing the first surface of the dismantling object on the inner surface of the opening into which the dismantling object is inserted. The pressing member is disposed at a position facing the second surface of the dismantling object inserted into the opening. The forward / backward moving mechanism moves the pressing member forward and backward between a forward position where the pressing member is advanced to the cutting blade side to cut the object to be disassembled and a backward position where the pressing member is retracted from the cutting blade side.

  In the disassembling apparatus of the present invention, the dismantling object can be cut by the cutting blade by moving the pressing member to the advance position by the advancing / retreating movement mechanism with the dismantling object inserted (set) in the opening of the frame. It becomes possible. That is, according to the present invention, the efficiency of the dismantling work can be improved with a simple configuration.

  In the disassembling apparatus according to the present invention, the frame has a third surface and a fourth surface on the back surface side, and the pressing member is disposed on the third surface side. Further, the advance / retreat mechanism moves the pressing member forward / backward along the third surface. Therefore, in the present invention, a shearing force can be effectively generated at a portion (cut portion) on the dismantling object between the third surface of the frame and the pressing member. The power can be improved.

  Furthermore, in the disassembling apparatus of the present invention, the frame is installed, for example, in a posture in which the third and fourth surfaces stand up, and the advance / retreat mechanism moves the pressing member up and down. In this case, the advance / retreat mechanism is configured to include a jack or the like.
