钢筋保护层塑料垫块应用中存在的问题及对策

The Problems in Application of Plastic Patch of Reinforced Protection Layer and Their Countermeasures

新的国家标准《混凝土结构工程施工质量验收规范》(GB50204-2002)的颁布和实施,对钢筋保护层厚度提出了更高的要求。钢筋保护层塑料垫块以其优异的性能、便捷的安装方法,在现浇钢筋混凝土工程中已得到了快速的推广和应用。这一技术有效提高了钢筋混凝土工程质量,克服了传统的砂浆垫块的工艺缺陷,完全满足新规范的要求。

The issue and implementation of the new national ＂Code for Construction Quality Acceptance of Concrete Engineering＂ （GB50204-2002） makes higher demands on the thickness of the reinforced protection layer. The plastic patch of reinforced protection layer, being of fine feature and convenient installation, is rapidly promoted and used in cast-in-site reinforced concrete construction. This technique greatly improves the quality of reinforced concrete construction. It overcomes the flaws of the traditional mortars patch and meets the demands of the new standard.
