Existing masonry structure using light steel structure direct storey-adding technology and construction method of existing masonry structure

Abstract

The invention relates to an existing masonry structure using light steel structure direct storey-adding technology and a construction method the existing masonry structure, and belongs to the field of seismic reinforcement of a structure. The construction method comprises the following steps: firstly, detaching a parapet wall, a cornice and a roof waterproofing layer of the original masonry structure before a storey is directly added onto the masonry structure; secondly, embedding steel bars into roof structural columns, and adding a ring beam, steel bars of a roof overlapped storey, and embedded screw rods in the newly-added ring beam; and thirdly, integrally pouring the steel bars embedded into the roof structural columns, steel bars of the newly-added ring beam, the steel bars of the roof overlapped storey, and the embedded screw rods to effectively joint a new structure and an old structure into a whole. When the concrete strength is higher than 70%, an upper light steel structure is installed. The existing masonry structure is restructured by directly adding a new storey through the light steel structure, the difficulty that people are short of houses at present can be relieved and a lot of land resources in China are saved, with significant economic and social benefits.

Description

technical field [0001] The invention relates to an existing masonry structure adopting the technology of directly adding layers of a light steel structure and a construction method thereof, belonging to the technical field of seismic reinforcement. Background technique [0002] As my country's economy and society enter a period of rapid development, land resources are becoming increasingly tense, and the proportion of building energy consumption in total energy consumption is increasing. The renovation and utilization of existing buildings has become one of the bottlenecks in urban construction and development. Using the scientific technology of adding floors to solve the expansion of existing buildings and to better realize the problem of building energy conservation through renovation should become an important area of ​​concern and research by the government and related enterprises. In recent years, due to the constraints of the economic conditions and construction techno...
