Research And Application Of Precast Hollow Wall Concrete Structure In Modern Rural Construction

At present, with the development of a thriving global economy, while environmental degradation has become a problem which can’t be ignored, energy conservation has become the priority issue of the countries all over the world, but also become China’s basic national policy. Construction has always been our country’s largest pillar industry of the national economy, but also the industry of the highest contribution of carbon emissions. So we must change the traditional extensive mode of production to the development of energy saving. The housing industrialization is our only road to solve the housing problem for over one billion people. With the construction of new socialist rural work deepening, the modern rural housing construction is gradually been concerned about. Rural housing construction has been showing the problem of large quantities and poor condition. To solve many problems of rural housing, now the central authority has a clear direction in the rural construction of housing industrialization.Against this background, this paper proposes a new form of connection structure: prefabricated hollow wall concrete structure using steel-anchor bolt, by summarizing the architecture of the modern rural housing construction and analyzing the current problems, in contrast to the advantages and disadvantages of the current application of the various forms of prefabricated structural connections. With the goal which is well looking and practical, safe and economical in order to adapt to the modern rural construction, we greatly reduce the weight of wall while reducing the difficulty of lifting and installation. To study of the overall seismic performance, this structure is compared with the same but a monolithic model. Using the general finite element analysis software ANSYS makes a two-floor-double-room full-scale simulated model, analyzes its seismic performance when loaded with EI-Centro seismic waves. Got the displacement-time curve for the top corner and the connection point between the floor, the cloud figure of internal force at key moment. Notice the key part of the structure and the weaknesses point which needs to be improved, and making an objective comment on this structure. At last, use "Rural House in the West of Sichuan" which designed by Sichuan HuaGou housing industrial Co. for the modern rural housing development of the prefabricated reinforced concrete house as an example, to study the application of the new connectional structure in the modern rural residence in the domain of the construction cost of the project, construction progress, quality and other aspects of construction, as well as make recommendations accordingly for the promotion of the structure in the modern rural residential application.
