Applied Research On The Examination Appraises And Reinforcement About One Elementary School's Teaching Building

As the rapid development of macroeconomic construction in china, the construction of the elementary and middle schools'teaching building has been developed rapidly. But, because of the damages, deterioration of the structures in the long-term use process; the flaw in the design,construction and management later; the change of the function in the later period uses; fire, earthquake and so on cidental factor influenced and code requirement enhanced. The elementary and middle schools'teaching building appear a lot of safe hidden dangers. In order to enhance the teaching building structures'security, reliability, durability. guarantee student's safety, reduce negative benefit. enable it better for the social service. Therefore. strengthening the elementary and middle schools teaching buildings structure reinforcement technology research give us important social meaning and huge economic efficiency, so,the reinforcement technology research has been one urgent and the stern topic at present.This paper apply the concrete structures thoery, architecture materials, the examination technology of the construction structure, the concrete structure appraisal theory,the concrete structure reinforcement construction technique, the durability of the engineering structure,each kind of approval standards, the structure analysis software of the PKPM and correlated with criterion and so on. The teaching building in zhengzhou was carryed on reliability assessment, structure system analysis, the design of the reinforcement plan, the craft of the reinforcement construction and various procedures development correlation theories computation analytical study. The main issues and rusults are as follows.(1) This chapter Elaborate the present situation and the reason of the present elementary and middle schools'teaching building, point out some survey and existence damage of the teaching building of one elementary school in zhengzhou city.(2) Based on correlated detection appraisal standard regulations and correlation technique, through spot investigation examination and analysis. Point out that this classroom building main body existence damages as well as forms these damages's reason. draw up the beam body's crack chart and give some reasonable suggestions.(3) Based on related design standard, Unified the PKPM structure analysis software, carry on the overall modelling computation analysis to the teaching building, check the security of the structure's each target. Based on computed result, actual state and related reinforcement standard, carry on the reinforcement design to the beam and wall of the elementary schools'teaching building, determines the reasonable reinforcement design proposal of the elementary schools'teaching building.(4) Based on correlation detection standard regulations, carry on some examinations to the reinforcement materials, discuss reinforcement construction steps of the steel plate reinforcement and steel bar net reinforcement and related attention. carry on the long-term monitor to this teaching building in the later period service process.(5) The research work of this thesis has been summarized,and the research trends in the future are has been forecasted.
