随着科学技术的发展,近年来住宅建设中的钢筋混凝土预制板逐步被钢筋混凝土现浇板所替代。但是,随着钢筋混凝土现浇板的推广和应用,现浇楼板出现变形裂缝的现象越来越常见,并且已经成为住宅质量投拆的热点。本文从设计、原材料和施工方面分析楼屋面出现裂缝的原因,从而提出了对于该问题的防治措施。 With the development of science and technology, reinforced concrete prefabricated slabs in residential construction have gradually been replaced by reinforced concrete cast-in-place slabs in recent years. However, with the popularization and application of reinforced concrete cast-in-place slabs, the phenomenon of deformation cracking in cast-in-situ floor slabs has become more and more common, and it has become a hot spot for housing quality. This article analyzes the causes of cracks in the roof of the building from the aspects of design, raw materials and construction, and proposes preventive measures for this problem.
