BUILDING BASED ON LARGE-SPACE STRUCTURE BODY AND FREESTANDING TYPE EXTERNAL ENVELOPE STRUCTURE, AND CONSTRUCTION METHOD

摘要

A building based on a large-space structure body and a freestanding type external envelope structure comprises a structure body and a freestanding type combined external envelope system. The structure body comprises vertical-structure reinforced concrete members, reinforced concrete girders and reinforced concrete floor slabs; the freestanding type combined external envelope system is disposed on the periphery of the structure body in a hanging manner. The structure body is made of prefabricated combined reinforcement cage member assemblies by means of concrete pouring, each prefabricated combined reinforcement cage member assembly is formed by a prefabricated vertical-structure reinforcement cage member, a prefabricated girder reinforcement cage member and a prefabricated floor slab reinforcement cage member by means of combination and assembly, and the prefabricated vertical-structure reinforcement cage member is a prefabricated shear wall reinforcement cage member or a prefabricated column reinforcement cage member. Also provided is a construction method for the building based on a large-space structure body and a freestanding type external envelope structure. According to the building, assembly of ultra-large members and construction of reinforced concrete civil buildings having large structure space can be implemented, the process is simplified, high-altitude operations are reduced, and the transferring cost is reduced.
