| With the rapid development of our economy and the progress of science and technology,space structure is used more and more widely used as the stadium, exhibition center, waitingroom, garage, large entertainment venues, public buildings, and increasing span, structureform also change rapidly. While the space grid structure is more with its simple structure,light weight, with its unique advantages and good visual effect is popular with people.Installation of steel truss structure in the process, the security of grid structure buildingis of concern, especially bending to be specification requirements for pressure parts of verticaland lateral bending of the rise and the main steel structure of the whole plane. But the steelbring hidden trouble to the safe use of steel truss structure. In the construction, the steelstructure deflection is becoming one of the aspects of the work of safety monitoring detection,deflection deformation is in accordance with the relevant specification determines directly thebuilding itself quality, construction quality construction unit.According to the Second Artillery Engineering College Swimming Pool grid project asthe background, the grid monitoring and construction quality acceptance on the basis of thereport, collect the defect structure in the construction. On this basis, using SAP2000finiteelement analysis software, discusses and studies the truss rod wall thickness deviation and thebearing bias effect on grid structure deflection. The grid structure for the quality control in theconstruction process and control the deformation of the grid structure provides a basis.Analysis for the effect of steel structure engineering in the construction process defectson its performance, using method, for the engineering quality control during the constructionof steel structure engineering include: the theory of quality control of three stage in theconstruction of steel structures, organization of production of steel structure enterprise, keyconstruction technology and quality control procedures. And spread through the use of theabove methods, reduce some common quality defects, which can improve the constructionquality of steel structure project of the whole society. |
