过去预制凉亭六角形钢筋混凝土柱子,当钢筋绑扎好、放入木模型壳后,往往很难垫衬好混凝土保护层,稍不注意就会露筋,影响构件的质量。后来,我单位用1:2水泥砂浆,预制像算盘珠子一样的水泥圆环,每隔20厘米一个,套在直立筋上。

In the past, the hexagonal reinforced concrete pillars of the pavilions were prefabricated. When the steel bars were tied and put into the wooden model shells, it was often difficult to cushion the concrete protective layer. A little care was taken to loosen the bars and affect the quality of the components. Later, my unit used a 1:2 cement mortar and prefabricated cement rings like abacus beads, one every 20 centimeters, on the upright ribs.
