Abstract

The invention provides a future dismantling considered reinforced concrete structure reinforcement method and belongs to the construction technical field. The future dismantling considered reinforced concrete structure reinforcement method specifically comprises the following steps of selecting a plurality of columns which are arranged in a structure to serve as destroy objects; adding a group of steel bars to the selected columns within the range of core area concrete of the selected columns on the basis of normal reinforcement; cutting off the steel bars which are arranged at the positions of the cross sections of the column top and the column bottom located in every column when a building needs to be dismantled; performing insulation treatment and drilling on cut-off surfaces of the steel bars to form a circuit with external power supplies; winding the columns a circle through an iron chain and connecting with an electric pull rod; starting every direct current power supply to enable the steel bars arranged in the columns to rapidly rust; shutting down every power supply and applying lateral tension to every column to enable every column to be destroyed and the structure to be collapsed towards the preset direction. According to the future dismantling considered reinforced concrete structure reinforcement method, the targeted treatment is performed on the building before the building is built so as to bring a great convenience to the dismantling in the future, the implementation process is convenient and feasible, and the economic value is great.

Description

technical field

[0001] The invention relates to a method in the technical field of construction, in particular to a method for reinforcing reinforced concrete structures considering future demolition. Background technique

[0002] At present, the rapid advancement of my country's urbanization and the rapid renewal of urban appearance have made the demolition of buildings more and more frequent. The existing demolition technologies for buildings at home and abroad mainly include blasting demolition method, prestressed demolition method, mechanical demolition method, static expansion pressure crushing demolition method, hot-melt cutting demolition method, etc. These methods can all achieve the purpose of demolishing the building, but what utilize all is to add the coercive effect, therefore expend manpower and material resources bigger, and cost is higher.

[0003] The prior art literature introduces the significant damage effect of the rust swelling effect of steel bars on c...
