Description

  The present invention relates to a dismantling system and a dismantling plan determination method. Specifically, the present invention relates to a dismantling system and a dismantling plan determination method for disassembling a structure.

Conventionally, in a high-rise building, there is a case where an existing building is dismantled and a new building is constructed due to the aging of facilities and structures.
Here, as a method for dismantling an existing building, for example, the following method has been proposed. In other words, a temporary roof made of a hat truss is provided on the top floor, and the space covered by the temporary roof is used as a dismantling work space, and the dismantling work is performed in this dismantling work space, thereby preventing dust and noise and building. Is disassembled (see Patent Document 1).

JP-A-6-272403

  By the way, in the above-mentioned dismantling method, after dismantling the floor to be dismantled, the dismantling material is unloaded using a crane. At this time, regenerative electric power is generated in the crane hoisting device. The regenerative power is thermally converted and discharged by a regenerative resistor or the like. If this regenerative power can be used, the environmental load can be reduced.

  An object of the present invention is to provide a dismantling system and a dismantling plan determination method that can reduce an environmental load by using regenerative power generated when unloading a dismantling material.

In the present invention, a crane for unloading the dismantled material disassembled, a power storage device connected to the hoisting device of the crane, and equipment in the demolition site connected to the hoisting device, When unloading the demolition material with a crane, it is preferable to generate regenerative power in the crane hoisting device, use the regenerative power as power for the crane, and supply surplus power to the equipment.

  According to this invention, when unloading a dismantling material with a crane, regenerative electric power is generated in the crane hoisting device. And while using this regenerative electric power as the motive power of this crane, surplus electric power is utilized for the apparatus in a demolition site. Therefore, since regenerative electric power is not released as in the prior art, energy use efficiency can be improved, and environmental load can be reduced.

The disassembly plan determination method according to claim 1 is a disassembly plan determination method for determining a temporary design image when disassembling a structure, and when unloading the dismantling material, a crane for unloading is unwound. The upper device generates regenerative power, uses the regenerative power as power for the crane, and supplies surplus power obtained by removing the power of the crane from the regenerative power to equipment in the demolition site, Calculate the amount of power generated by regenerative power based on the number of times of unloading, the height of unloading, and the weight of the dismantling material, and calculate the amount of power shortage in the dismantling site based on the calculated amount of power generation. The power amount to be determined is determined to be supplied from an external power source.

  According to this invention, the power generation amount of regenerative electric power is calculated based on the number of unloading times of the crane, the unloading height, and the height. Next, based on the calculated power generation amount, the amount of power shortage in the dismantling site is calculated. And it determines so that insufficient electric power may be supplied from an external power supply. Therefore, the amount of power supplied by the external power source can be calculated in advance, and the environmental load can be reduced.

  According to the present invention, when unloading the dismantling material with a crane, regenerative power is generated in the crane hoisting device. And while using this regenerative electric power as the motive power of this crane, surplus electric power is utilized for the apparatus in a demolition site. Therefore, the regenerative electric power generated in the crane hoisting device when unloading the demolition material can be used to cover the electric power in the demolition site, thereby reducing the environmental load.
