Automatic steel bar dismantling device for high-altitude building
Technical Field
The utility model belongs to the technical field of building dismantling equipment, and particularly relates to an automatic steel bar dismantling device for a high-altitude building.
Background
When high-altitude buildings such as pier stud tie beams and bent caps are constructed by adopting a steel bar method, the risk of the steel bar dismantling working process is extremely high, no high-altitude operation personnel up-down channel and operation platform are arranged on the building, only a crane matched with a hanging cage can be used as a construction operation platform for dismantling the high-altitude operation up-down moving mode of construction operation personnel in the steel bar dismantling working process, and the hanging cage platform still bears irregular reverse acting force to shake continuously in the process of construction and steel bar removal, so that not only is the falling risk of the construction operation personnel from the high-altitude, but also the operation platform cannot bear too large extraction reverse acting force, and the steel bar dismantling efficiency is extremely low.
In the prior art, patent document with publication number CN 113152928B discloses a method for dismantling super high-rise building, comprising the following steps: step 1, building a peripheral operation platform of a building; step 2, pre-dismantling; step 3, perforating and charging; step 4, safety protection; step 5, dust fall and noise reduction protection; step 6, detonating the explosive; step 7, after blasting is completed, the slag removal team enters the field to clear the slag soil; step 8, after the slag removal is finished, building a temporary support of the layer, and cutting, lifting and lowering a top plate structure of the first dismantling unit; step 9, static cutting dismantling and lifting lowering are carried out on the static cutting area; and 10, constructing in a construction circulation mode until the floor is one layer, and finishing. The scheme is applied to demolishing abandoned high-rise buildings, is not suitable for demolishing steel bars remained after the steel bar method is constructed independently, and is not possible to build a complex operation platform for demolishing the steel bars because the steel bars are supporting structures for bearing the mould and the construction platform in the building construction process and can only be demolished after the pier column templates and the construction platform are completely demolished, and otherwise, the construction of adopting the steel bar method is inverted.
