钢筋保护层垫块的质量,直接影响到建筑物的结构。一般采用水泥砂浆制作垫块,其表面是平的。在垫支钢筋时,由于钢筋接触垫块面积小,砂浆强度较低,在混凝土浇筑过程中如被踩踏或压重物,很容易损坏。图1改进后的钢筋保护层垫块改进后的钢筋保护层垫块(图1),可根据保护层的厚度进行
The quality of the protective layer of the steel reinforcement directly affects the structure of the building. Generally use cement mortar to make pads, the surface is flat. In the reinforcement of steel bars, due to the small area of the contact pads of the steel bars and the low strength of the mortar, it is easily damaged if it is stepped on or pressed by heavy objects during the concrete pouring process. Fig. 1 Improved steel protective layer cushion The improved steel protective layer cushion (Fig. 1) can be made according to the thickness of the protective layer.
