Reverse dismantling method for high-rise frame structure

Abstract

The invention relates to a reverse dismantling method for a high-rise frame structure, and belongs to the field of building construction. A reverse dismantling method for a high-rise frame structure comprises the following steps that S10, wall structures of the first layer and the second layer are dismantled, beam plates of the second layer are dismantled, frame columns are all dismantled, and the frame columns are replaced with steel columns; s20, the concrete beams on the second layer are dismantled, the main beams are replaced with the steel beams, a plurality of jacking devices are fixed to the steel beams at intervals in the steel beam replacing process, and the jacking devices are used for jacking and supporting the main beams on the third layer; s30, the pushing device is driven to contract, the high-layer frame structure descends, frame columns on the second layer fall into the operation space, and the frame columns on the second layer are dismantled; s40, wall structures and beam plates of the third layer are dismantled, concrete beams of the third layer are dismantled, a jacking device is used for jacking and supporting main beams of the fourth layer, a pushing device is driven to contract, and frame columns of the third layer are dismantled; and according to the step S40, the high-rise frame structure is dismounted layer by layer. The dismantling method for the high-rise frame structure is high in dismantling speed, environmentally friendly and low in labor intensity.

Description

technical field [0001] The invention relates to a reverse dismantling method of a high-rise frame structure, and belongs to the field of building construction. Background technique [0002] The frame structure is a structure composed of a plurality of concrete beams and frame columns to bear all the loads of the house. Among them, the concrete beams include the main beam and the secondary beam. In high-rise civil buildings and multi-storey industrial plants, the load-bearing of brick walls can no longer meet the requirements of large loads, and frames are often used as load-bearing structures. [0003] Two methods are usually used for the demolition of high-rise frame structures: one is the blasting method, which pollutes the urban air greatly, and this method poses a threat to the surrounding buildings and is extremely unsafe; the other is the partial demolition method from top to bottom. In this method, the transportation of the dismantled waste material has the problem o...

[0003] Two methods are usually used for the demolition of high-rise frame structures: one is the blasting method, which pollutes the air in the city, and this method poses a threat to surrounding buildings and is extremely unsafe; the other is the partial demolition method from top to bottom, using In this method, there is a problem of low transportation efficiency in the transportation of the demolished waste, and there is a problem of poor safety in high-altitude transportation
