{Manufacturing Method of Lightweight Assembly Scaffold for Removing and Attaching Exterior Wall and Method of Dismantling Structure Using It}

The present invention relates to a manufacturing method of a lightweight assembly scaffold for exterior wall and a method of dismantling a structure using the same, and more particularly to a construction method of a lightweight assembly scaffold which can be detached and attached to a building without using heavy equipment And a method for disassembling a structure using the same.

Most of the buildings were built to be used semi-permanently, but due to social change and economic development, the life span of the building has been reduced to less than the structural life, and the functional aspects of the building, supplementation of facilities, natural disasters such as earthquake or fire, urban redevelopment etc. Public elements are increasing the need to demolish buildings.

Especially, the buildings located in the center of the city center should be paid attention to the operation of the buildings located in the area where the traffic of passengers and passengers is large and the distance from the neighboring buildings is narrow or the roads and guideways are close to each other.

In the existing demolition method to demolish such a building, first a scaffold is installed around the outer wall of the structure, such as a steel pipe pipe, footsteps and a safety net, and then a crusher is usually attached to a large excavator, Since it is not suitable, a small excavator is hoisted on the upper layer with a crane, and a combination of a crusher or a breaker is sequentially applied to the upper and lower layers in order to remove the excavator.

Especially, when the outer wall of the building is demolished, the mass of the concrete, which is the demolished crushed material, falls between the outer wall of the building and the safety net, and breaks the safety net frequently. Further, the collapse of the adjacent building due to falling objects, In the case of any large-scale external wall, a scaffold and a safety net may be conducted together to cause a large-scale safety accident as shown in FIG. 1 and FIG.

In order to prevent such accidents, Korean Utility Model No. 20-2003-0000749 "Blocking Device for Blocking Fragments, Noises, and Dust Generated by Demolition of Building Structure", Korea Patent Application No. 10-2005- 0044258 "Building demolition apparatus and method" and the like are disclosed.

The above-mentioned conventional patents commonly have a structure in which a safety net or a scaffold surrounds an outer wall, and such a structure contains the risk of the above-described conduction and collapse as it is.
