Definitions

  • the present invention relates to a building demolishing method which is adaptable for demolishing a building, particularly a high building.
  • a method for demolishing a building, a method is adapted in which a scaffolding is put up around a building to be demolished to cover the whole building and a demolishing is carried out sequentially from an upper story.
  • the apparatuses for demolishing the building as a whole tends to become heavy.
  • a heavy machine such as a giant crane is required for lifting up the whole apparatuses for demolishing the building, so that there are problems that the work tends to become difficult and need a lot of time, and the shielding apparatus which discloses carries risk to be flapped by strong winds on a high airy region, as the building to be demolished becomes higher.
  • the floor face itself on which the work is carried out is a floor to be demolished, the floor face space for working becomes narrow as the demolishing work progresses and the working property becomes extremely in bad situation. Therefore, it is considered to mount a demolishing machine on a lower story below a story to be demolished so as to always secure the scaffolding which is necessary for demolishing the building.
  • An object of the present invention is to provide a building demolishing method in which structuring a shield does not require a large-sized heavy machine and a scaffolding which is necessary for demolishing a building is always secured so as to smoothly progress a demolishing work.
  • the building demolishing method described in claim 1, for example, as shown in FIG. 1 (FIG. 8), comprises:

  • the assembling work can be substantially simplified. Therefore, it is suitable for consisting of the shield by a member which has a strength and high stiffness enough to stand strong winds at the high story of the building and a member which has high sound and heat insulating properties.
  • the guide column member is lifted up by the crane which is attached to the shield and connected to the upper end portion of the guide column to sequentially extend the guide column upward.
  • the guide column member which is at the upper end portion of the guide column is removed and lifted down by the crane to sequentially shorten the guide column downward. Accordingly, when structuring or demolishing the guide column, there is no need to separately prepare a crane for structuring or demolishing the guide column because the crane which is attached to the shield can be used.
  • Each story of the building is sequentially demolished downward from the highest story, and each time the story to be demolished moves downward, the shield is sequentially descended to cover and enclose the lateral periphery of the story to be demolished.
  • the leakage of dust or noise which is generated when demolishing the building to outside from the side of the story to be demolished can be prevented.
  • the shield which covers the lateral periphery of the story to be demolished can shut off wind and weather, so that a good working environment for the story to be demolished can be secured. Accordingly, the demolishing work is less affected by the weather, and the demolishing work can be progressed smoothly.
  • the demolishing machine for demolishing the building is stored in the storing space which is provided in the shield, and the storing space is adjacent to the building.
  • the demolishing machine can be carried easily to the desired story of the building by ascending or descending the shield. That is, it is not necessary to provide a crane for lifting up or lifting down the demolishing machine outside the building to carry out a lifting work. Accordingly, the demolishing work can be carried out with the construction cost for lifting the demolishing machine considerably reduced.
  • the low story indicates a story at the level of, for example, a second story to a fifth story, and the story which is preferable for carrying out the building demolishing method is accordingly selected among these stories depending on the site conditions on which the building to be demolished is built.
