Problems solved by technology

[0003] The demolition of existing urban structures is different from the demolition of ordinary buildings and structures. Its characteristics are: 1. The demolition of structures is often partially demolished and rebuilt after demolition. Various types of original structures and different working environments lead to the safety of the structures to be demolished. Insufficient evaluation; 2. The demolition environment in the city is complex, often near bustling commercial areas, tourist areas, and residential areas, and the requirements for safe and civilized construction are extremely high

Embodiment

[0028] A kind of preparation method of reinforced concrete structure static breaking construction method, such as figure 1 , 2 shown, including the following steps:

[0029] S1. Construction preparation: collect the as-built drawings of the structure to be demolished and other information, and understand the original structure size, structure and other information; use water drills to open hoisting holes on the floor with a size of 4m*4m, and transfer the supporting frame and other materials to the floor for storage. After the material transportation is completed, continue to open the hole downward to hoist the material of the next layer; cut off water, power, and gas, and remove the decorative layer (including floor pavement), pipelines, and electromechanical equipment; Pneumatic picks will chisel out the concrete of the beams and shear walls at the position where the reinforcement is thrown, and the reinforcement will be retained (the reinforcement will not be cut for the t...

Abstract

The invention provides a static breaking construction method for a reinforced concrete structure. The static breaking construction method comprises the steps of construction preparation, temporary full space supporting frame erecting, beam and slab dismantling construction, cast-in-place stair dismantling, beam and slab building slag outward transporting, wall column dismantling construction, wall column building slag outward transporting, next-layer dismantling and the like. According to the method, the full-space supporting frame is erected on the lower portion of the demolition area, the demolition object is hoisted in time, the requirement for the bearing capacity of the structure to be demolited can be greatly lowered, the construction safety coefficient is increased, and meanwhile potential safety hazards caused by structural vibration can be reduced.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete structure demolition, in particular to a construction method for static demolition of reinforced concrete structures. Background technique [0002] With the continuous advancement of my country's urbanization process, more and more people have migrated to cities, resulting in a sharp increase in rigid demands for residence, living space and service facilities. The reason is that it can no longer meet the material and spiritual needs of urban residents. On the other hand, with the continuous adjustment and upgrading of my country's urban industrial structure and the spatial reconfiguration of economic and social development factors, the vitality of many old urban areas has been lost and the spatial value has weakened. On the basis of the game of urban land stock, the concept of urban renewal came into being, and the types of urban renewal mainly include three categories: comprehensive r...
