Description

The present invention relates to retrofitting measures for existing buildings, and more particularly to an adapter system for alternate construction of new and existing structures.

Upgrading and renovating underground spaces in urban centers is an important means of alleviating the shortage of urban resources and adapting to the rapid development of cities. At present, most of the underground space renovation is the local functional renovation of the existing structure or the exploitation and utilization of the original city's invalid underground space. On the other hand, the exploitation and utilization of invalid spaces in cities is a purely new structural system. When it is necessary to renovate the main load-receiving system of the existing structure in renovating the underground space, it is often the case that the entire structure is dismantled and then rebuilt. However, the environment around the city center is complicated, and the process of building a new building after dismantling the entire building has a great impact on the environment, which seriously limits this construction method.
