摘 要:现浇板负弯矩钢筋保护层偏差直接影响到钢筋混凝土板的力学性能及耐久性,关系到建筑物的使用安全及使用寿命,现行混凝土结构验收规范要求在验收时必须提供保护层厚度实体检测结果,因此,在设计和施工中应采取有效措施保证保护层厚度的准确性,以确保构件的正常使用,提高工程质量。
Abstract: Negative bending moment reinforced protection layer deviations of in-situ slab can directly affect the mechanical properties and durability of reinforced concrete slabs, which is relative to the using safety of a building and its service life. The existing concrete structure acceptance specification requires that the entity test results of protection layer thickness must be supplied when doing acceptance, therefore, during the design and construction, effective measures to guarantee the accuracy of protection layer thickness should be taken, which can ensure the normal use of components and improve the engineering quality.
