Applied Research On The Detection Identification And Reinforcement About One Floor Cracks

Concrete is the most widely used in the construction of the building materials;But, since the material properties of discrete factors, structure complexity, diversity,and environmental construction uncertainties and other factors, they cause differentforms of structural cracks, These cracks not only affect the exterior of the building,while affecting structural durability, serious building will lose its functionality.Therefore, How to carry out the objective of effective Detection and identification ofconcrete cracks, propose appropriate and reasonable reinforcement programs,improve the structure of the safety and durability, it is very urgent. Therefore, toenhance the study of the detection and identification of concrete structure cracks andreinforcement technology, it will have great practical significance and high economicbenefit; it is very necessary and urgent issue.This paper based on the concrete structure basic theory, the computationalmethods of engineering structures detection and identification technologies, thetreatment technology of the crack, the technology of the structural reinforcement,,the durability of the concrete structure, the regulations and norms related tostructural Integrated use of the basic theory and computational methods ofengineering practiceï¼› One shopping plaza floor cracks were carried on detectionand identification, the reason analysis, the design of the reinforcement constructiontechnology programs and explore the construction process and related theoreticalcalculations. The main work is as follows:(1) This chapter elaborates the properties, causes and hazards of the cracks inconcrete structures, pointed out the project profiles and the diseases of the floorshopping mall;(2) Based on the relevant technical regulations and specifications, throughon-site inspection and survey analysis, point out the presence of cracks in the floormember and the causes of these cracks, draw the cracks diagram; Based on the testresults, the analysis of various indicators were checked and the detection andidentification conclusions were given. (3) Based CECS293-2011and other regulations, cracks in the concrete structureare classified, according to the crack width, and put forward feasible and reasonablemeasures to crack repair processing; combined GB50367-2006standard, the floor isreinforced calculations, based on the analysis results and the actual situation,determine the slab reinforcement design and construction drawings;(4) Based on the relevant technical regulations and specifications, the relatedparameters of reinforcing materials were tested; Investigate crack repair, CFRPreinforcement construction process and construction points. Last, proposing thelong-term monitoring of the floor in the late service;(5) The research work of this thesis has been summarized, and the researchtrends in the future are has been forecasted.
