Existing Housing Construction Comprehensive Analysis Of The Whole Process Of Renovation Project

The safety of the building structure is directly related to the people’s life and property, especially the safety of the houses after the earthquake in Wenchuan is getting more and more attention.. The damage of the structure and the load and the non- load factor to the structure has been affected by the time, and the use and safety of the buildings are affected by the construction. In our country since the sixties of the 20 th century began building reinforcement and reconstruction work, through nearly half a century of in our country lack of seismic capacity of existing building reinforcement engineering practice, for China’s construction of strengthening the development of new technologies, new materials accumulated a wealth of practical experience, also in the old building reinforcement also published many papers, effectively promote the seismic strengthening theoretical study of the depth. In this paper, the seismic retrofit of existing buildings in different situations is classified, and the design and construction methods involved in seismic retrofit are studied.. Seismic strengthening of the guidelines apply to in "transformation", "recovery" and "perfect" maintenance process and change the mechanical characteristics of the structure, so as to improve the overall performance. In view of the existing technologies, in many reinforcement method, the guidelines provides detailed design and construction methods including for external pipeline construction method, construction method of bonding layer and cover layer construction method. This paper can not meet the structural reinforcement of every design and construction. In addition, the design and construction of reinforcement structure with the progress of technology, will produce more advanced construction method. However, the advanced construction method, its foundation and transformation method will undoubtedly be the same, so these essentials should observe the actual situation and can be adjusted according to the situation of the scene. It should be noted that, in general, structural reinforcement technology at the research stage, many things have not been completed. At the same time, in the structural transformation, according to the guidelines, but after the transformation of structure were maintained properly is very important also only in this way, the security of housing to for a long time for people to go.
