近年来,传统的预制板逐渐被现浇板所取代,由于使用了现浇板,房屋的整体性、抗不均匀沉降性和结构安全性均有很大提高,但也伴随产生了一些楼板裂缝的情况,这些裂缝绝大部分并非因结构受力所引起的,不影响结构安全,但却影响美观,又容易使住户产生心理上的不安,而且裂缝不仅会影响抗渗效果,也易造成水分侵蚀钢筋,影响使用耐久性。因此,应引起设计,施工,监理等单位的重视,通过合理设计,精心施工,杜绝现浇板裂缝的产生。
In recent years, traditional prefabricated panels have been gradually replaced by cast-in-place panels. As a result of the use of cast-in-place panels, the integrity of the houses, uneven subsidence and structural safety have been greatly improved, but some floor cracks have been accompanied The majority of these cracks are not caused by structural forces, do not affect the structural safety, but have an impact on the esthetic appearance and easily cause psychological distress to the tenants. Moreover, the cracks not only affect the anti-seepage effect but also easily lead to moisture Erosion of steel, affect the use of durability. Therefore, should pay attention to the design, construction, supervision and other units, through reasonable design, meticulous construction, to prevent the emergence of cracks in the cast-in-place.
