大梁裂缝的原因分析及加固处理（Analysis and reinforcement of the fracture of girder）

大梁裂缝的原因分析及加固处理（Analysis and reinforcement of the fracture of girder）Analysis and reinforcement of the fracture of girderAbstract: this paper analyzes the reason of the fracture of a certain project girder and introduces the reinforcement treatment and construction method.Key words: the reason of the crack of the girder is the analysis of the structure of the construction of the structure of the construction of the structure of the construction of the construction of the construction of the construction of theThe comprehensive office building of a technical school in xinxiang city of henan province is a six-story brick and masonry structure, among which 9.9 m x 6.5 m in the classroom, the span of the girder is 6.5 m, the beam is 600mm, and the girder is mixed concrete with C25. Project put into use in 1997, four years later, the four layers of A, B (2), (3), (5), 6 axis, C, D (2), (3), (5), 6 axis, A - B [14], five layer ⒂ shaft bottom girder beam and beam side appears irregular longitudinal crack and oblique crack, pose serious security hidden danger of the project.The construction quality supervision station of xinxiang city and the relevant experts of xinxiang municipal institute of architectural design have carried out the field survey and proposed the reinforcement plan, which is to be strengthened by our company. The reinforcement situation will be introduced.1. On-site investigationThe maximum fracture width of 110 girder beams is 0.8mm, and the seam reaches 30 to 50mm, and the crack is chipped away, and it is found that the steel bar is corroded, and the local rust is serious.1.2 at both ends of the beam, the maximum fracture reaches 0.5mm, and the seam reaches 20 to 40mm, and the crack is gouged out and it is found that the stirrups are also etched.1.3 according to the verification, concrete pouring, the main body structure coincides with winter, the temperature is lower, the mixing concrete mixed with antifreeze of chlorine ion, complete information on the
