Description

  The present invention relates to a dismantling machine that moves a dismantling machine to the top of a building and lowers the building while dismantling the building with this dismantling machine, and a dismantling method of the building that uses this dismantling machine. The present invention relates to a demolition machine and a demolition method that are most suitable for the demolition of buildings in which a crane that lifts the demolition machine cannot be arranged.

  Currently, the building is demolished in the following way. The most common dismantling method is a method in which a dismantling machine equipped with a large arm that reaches the roof of the building is approached to the outside of the building, and the building is dismantled from the outside with this dismantling machine. Since this method places a large scale weighing machine close to the building, it requires a wide road and site around the building. For this reason, buildings with no wide roads or open spaces around cannot be dismantled by this method. In addition, buildings with electric wires and utility poles around them cannot be dismantled due to these obstacles.

  Buildings with no wide roads or open spaces are lifted at the top of the building, and the entire building is demolished by descending while dismantling the building. This method also requires a space for placing a crane for suspending the weight lifting machine around the building when the weight lifting machine is lifted by a crane. For this reason, a building weightless machine cannot be lifted above the building in a building that does not have a road or vacant land around it.

  In order to eliminate the drawbacks of this method, a dismantling method has been developed in which a crane for lifting a weight lifting machine is fixed on the roof of a building, and the weight lifting machine is lifted to the upper part of the building by this crane. (See Patent Document 1)

JP 2014-47479 A

  In the conventional method, a platform is installed on the roof of the building, a lifting winch is installed on this platform, the lifting machine is lifted to the upper part of the building, and the building is demolished with the lifting machine moved to the upper part. Descent and demolish the entire building. This method has a drawback that this work is extremely troublesome because a pedestal and a lifting winch are installed on the roof of the building. In particular, a lifting winch that lifts a heavy lifting machine can be quite heavy, so it takes a lot of time to lift a heavy lifting winch or pedestal to the top of the building, and to install them on the roof of the building. There is a shortcoming that takes time. Furthermore, since heavy lifting winches and platforms are moved to the top of the building, it is extremely difficult to move them safely. This is because heavy lifting winches and platforms cannot be moved by building elevators. In particular, many buildings to be demolished stop the operation of the elevator, and even if the lifting winch or base can be disassembled into a size that can be mounted on the elevator, it cannot be lifted using the elevator, and the base and the lifting winch. There are drawbacks in that it takes a lot of time to lift and set up and it is difficult to ensure the safety of work.

  Further, in the conventional method, in order to lift the weight lifting machine with a lifting winch installed on a gantry provided on the roof of the building, the building is provided with a passage hole for passing the weight lifting machine over a plurality of floors, and each floor. The through holes opened in the are arranged in a straight line in the vertical direction. As described above, it is extremely troublesome to form a large passage hole through which a weight-removing machine can pass over a plurality of floors of a building. The reason is that we cannot use a weight-removing machine that can destroy concrete. For this reason, it is necessary for an operator to open using an electric hammer or the like for crushing concrete, and there is a problem in that this work takes time and labor and increases costs.

  Furthermore, since the passage holes that are opened over a plurality of floors are provided in a straight line in the vertical direction so as to allow the lifting weight lifting machine to pass through, a through-hole portion that is continuous in the vertical direction is formed in the building by these passage holes. The As described above, there is a problem that the blow-through portion having the difference in height has a risk that an operator may fall in the forming process or materials and waste materials may be dropped from a high place, and the working environment is extremely deteriorated.

  The present invention has been developed for the purpose of solving these drawbacks. An important object of the present invention is to provide a building demolition machine and a demolition method that can easily and easily move a demolition machine to the upper part of the building, and can safely dismantle the building while reducing the demolition cost of the building. There is to do.

Means for Solving the Problems and Effects of the Invention

The method of demolishing a building according to the present invention includes a heavy equipment moving step of moving the weight removing machine 1 equipped with a demolishing tool 12 at the tip of the arm 2 to the heavy machine main body 4 to the upper floor of the building 20, The dismantling machine 1 moved to the floor dismantles the building in a dismantling process in which the building 20 descends while dismantling the building 20 from the upper floor to the lower floor. The heavy equipment moving process includes a heavy equipment preparation process in which elevators 5 having a lifting force and a stroke capable of pushing up the weight lifting machine 1 to the upper floor are installed on both sides of the weight lifting machine 1 , and a ceiling 27 on the floor where the weight lifting machine 1 is disposed. A step of opening a passage hole 23 that can pass through the dismantling machine 1 by breaking the disassembly tool 12 into the floor 22 on the floor, and a heavy machine pushing up the dismantling machine 1 by the elevator 5 and passing it through the passage hole 23 In the state where the lifting machine 1 is pushed higher than the floor where the passing hole 23 is opened, the supporting member 26 is bridged to the passing hole 23 below the lifting machine 4, and then the heavy machine body 4 is lowered by the elevator 5. And a heavy machine support step for supporting the weight- removing machine 1 on the support member 26. Further, as a subsequent step of the heavy machine support step, the weight-removing machine 1 supported on the support member 26 is allowed to run. Floor of the floor The opening process, the heavy machine push-up process, the heavy machine support process, and the transfer process are repeated to move the weight-removing machine 1 to the upper floor of the building over a plurality of floors. In the push-up process, the elevator 5 pushes the floor surface and pushes the heavy machinery main body 1 up to the upper floor, and changes the position where the lift machine 1 is pushed up. Move to the upper floor.

  The above dismantling method has a feature that the dismantling machine can be moved to the upper part of the building simply and easily and quickly, and the building can be dismantled safely while reducing the dismantling cost of the building. The above dismantling method is not a conventional method of installing a platform or a lifting crane on the roof of a building and lifting the dismantling machine with a wire. This is because the heavy machinery is moved to the top of the building. In particular, in the above dismantling method, when pushing up the dismantling machine, part of the ceiling of the floor where the dismantling machine is placed is destroyed with a dismantling tool and a passage hole is opened, so it passes easily and easily through the dismantling machine. The passage hole to be opened can be opened in the concrete on the upper floor. For this reason, as in the past, without opening a large passage hole in advance on the floor of each floor, a dismantling machine that is moved to the upper floor is used to destroy a part of the ceiling with a demolition tool and open the passage hole. Meanwhile, the weight lifting machine pushed up by the elevator is passed through the passage hole, and the weight lifting machine is pushed up to the upper floor of the building. Moreover, since the above demolition method can reduce the expense which opens a passage hole in the floor concrete of an upper floor, the characteristic which can reduce the total cost for demolishing a building is also implement | achieved. In addition, as in the past, without forming an atrium-like opening communicating from the upper part of the building to the lower floor, a passage hole is opened in the upper floor, which is the ceiling, and the weight-removing machine is pushed up by the elevator to pass through Since it passes through the hole and moves to the upper floor, there is no need for dangerous work, and a feature that allows the dismantling machine to be safely moved to the upper part of the building and demolished is realized.

  In the building dismantling method of the present invention, the elevator 5 includes a plurality of jacks 13, and the jack 13 includes a cylinder portion 14 arranged in a vertical posture and a rod portion 15 that is inserted into and removed from the cylinder portion 14. In the heavy machinery push-up process, the lift 5 can push the rod-developing machine 1 up to the upper floor by causing the rod portion 15 to protrude from the cylinder portion 14.

  In the building demolishing method according to the present invention, in the heavy machinery support process, after the support member 26 is bridged to the passage hole 23 through which the weight-removing machine 1 has passed, the jack 13 stores the rod portion 15 in the cylinder portion 14, and the weight-removing device 1. Can be placed on the support member 26.

  The building dismantling method of the present invention includes a step of entering the dismantling machine 1 supported on the support member 26 and traveling on the floor of the upper floor as a post-process of the heavy equipment supporting process. On the floor where the vehicle enters, the opening process, the heavy machine push-up process, the heavy machine support process, and the transfer process are repeated to move the weight-removing machine 1 to the upper floor of the building 20 over a plurality of floors.

  In the above dismantling method, after the dismantling machine that has passed through the passage hole and pushed up to the floor is run on the support member and placed on the upper floor, the opening process, the heavy machine pushing process, the heavy machine supporting process, and the boarding process are performed. Since the weight-removing machine is repeatedly moved to the upper floor of the building over a plurality of floors, the weight-removing machine can be moved to the upper floor of the building while changing the place where the passage weight is opened and the weight lifting machine is pushed up. For this reason, the weight-removing machine can be moved to the top floor of the building while reducing the height difference of the aerial portion formed by the passage hole opened in the building and extending vertically. In particular, with the dismantling machine on the upper floor, a part of the ceiling is destroyed with the dismantling device of the dismantling machine and a passage hole is opened in the upper floor, so that the dismantling machine is stably supported on the floor. The passage hole can be opened safely. In addition, the weight lifting machine can be pushed up and passed through the passage hole while moving to the upper floor while stably supporting the lower end of the elevator on the floor surface.
