钢筋在混凝土中的位置和钢筋保护层的厚度,对钢筋混凝土的受力性能和建筑物的耐久性是至关重要的。我国通常采用砂浆制作垫块来保证钢筋保护层的厚度,但在施工中往往由于垫块的脱落、破碎而导致钢筋移动、走位,保护层的厚度也出现较大的偏差,有些结构由于钢筋下垂、移动造成露筋。特别是当前在测定保护层厚度的手段尚不完善
The position of the reinforcing steel in the concrete and the thickness of the protective layer of the steel are critical to the mechanical properties of the reinforced concrete and the durability of the building. Our country usually uses mortar to make pads to ensure the thickness of the protective layer of the steel. However, in the construction, the steel bars tend to move and take a position due to the detachment and breakage of the pads. The thickness of the protective layer also shows a large deviation, and some structures are reinforced. Sagging, moving caused dew. In particular, the current method of measuring the thickness of the protective layer is not perfect
