Description

Closed construction method and building Technical Field The invention relates to the technical field of building construction, in particular to a closed construction method and a building. Background Urban development in China has been shifted from incremental expansion to stock quality improvement and synergy stages. The implementation of city updating is an important measure for promoting the high-quality development of cities. A large number of urban updating projects are focused on old urban areas where buildings are dense. Old urban buildings mainly have low multi-storey, and have the characteristics of narrow space, dense building population and traffic congestion. The surrounding roads are narrow, vehicles are difficult to pass, meanwhile, the problems of shaking buildings and flying lines exist in the close vicinity or close vicinity of the buildings, so that construction equipment is difficult to transport or cannot pass, a large amount of surrounding roads are occupied by site construction, a closed working environment cannot be formed, meanwhile, dust, noise and the like generated by site mechanical operation influence the life of surrounding residents, a large amount of residents complain, larger social and economic influence is brought, and the problems become a main obstacle for restricting the transformation of old buildings. Aiming at the construction projects of the buildings in the dense areas, the existing construction and construction mode generally needs to occupy surrounding sites to set up surrounding barriers and set up scaffolds for construction operation and protection, a building structure system is separated from a construction surrounding barrier and an operation protection system in the construction and construction mode, temporary facilities such as the surrounding barriers and the scaffolds are required to be removed after the construction is completed, the whole construction process is exposed in urban environment, the construction period is long, the field wet workload is large, the occupied sites are large, the three-dimensional totally-enclosed construction sites cannot be formed, noise and other environmental pollution generated in the process are large, and the influence on urban landscape is large.
