Analysis And Prevention Measures Of Conventional Cracks For Buildings

As one kind of universal shortcoming of architectural engineering quality, the wall crack not only affects the building artistic and the use function request, but also can destroy the wall's integrity, affects the structure safety, even can reduce the durability of structure .Therefore we should take measures to reduce and prevent the crack occurs. Seek methods for wall crack controlling, propose the correlation preventions and the control measures, have the extremely important theory value and the practice significance.Combined with actual engineering construction to research on the frame construction infilled wall crack, the basement concrete wall crack, the brick masonry structure wall crack, the reinforced concrete floor crack, the outer wall heat insulation plastering level crack and the inner wall lightweight partition board crack ,point out spots and characteristics of the wall cracks , the causes of wall crack were described, including: Design, construction technology, temperature stress, concrete shrinkage, unequal settlement of the foundation , material own factors and other aspects. According to the engineering practice, corresponding prevention measures are proposed in order to control crack from design and construction, summarize the crack appraisal methods and the crack repair methods. This article has certain practicalsignificance to guarantee the project quality and prevent the common failings.Finally the summary/suggestions of the wall crack were brought up.
