免绑扎混凝土保护层垫块的设计与施工质量控制

Design and Construction Quality Control of Free Lashing Concrete Protective Layer Pads

钢筋保护层厚度偏大或偏小是影响现浇楼面质量的主要问题.介绍了钢筋保护层在现浇楼板中的偏差及危害、现有现浇楼板保护层控制措施和带弹簧卡的免绑扎式混凝土垫块.重点对带弹簧卡的免绑扎式混凝土垫块的设计和施工质量控制技术进行了论述,对现浇楼板保护层的质量控制具有借鉴意义和推广价值.

The major problem affecting the quality of the cast floor is the thickness of concrete protectire layer. The bias and harms of the concrete protective layer in the floor slab,concrete protectivelayer control measures of the existing floor slab and free lashing concrete pad with spring card are introduced,focusing on the design and construction quality control technology of free lashing con-crete pad with spring card,which would be of reference and promotional value for quality control of concrete protective layer.
