Prefabricated architectural structure of a building in the factory prefabricated, transported to the construction site, the workers a spliced into industrial production overall. This mode of production to the fast speed of construction, economic benefit and environmental benefit has been paid more and more attention of owners and designers. However, the current structure assembly type structure connection reliability is poor, the prefabricated frame structure used in seismic area is limited. At the same time, prefabricated buildings in bad economy in actual construction defects. Based on this, discusses the joint structure and the economy of prefabricated building structures.
In this paper, based on a lot of reading existing literature summary and become, by assembling building production, research and development and structure of the system, put forward the necessity of the development of prefabricated construction in our country, and to solve the problems existing in our current building, in the building structure node structure were summarized construction technical feasibility, also the seismic performance and technology economy bad for assembling building to do the analysis, to find a solution to the problem.
Keywords:Prefabricated; structure system; node structure; seismic performance; economic performance
