在现浇钢筋混凝土结构中,特别是民用建筑,存在着大量预埋管线与主次梁钢筋绑扎的工作,但是在实际操作中,存在着梁特别是梁中间部位混凝土保护层厚度难以控制和PVC管线成品保护不好的现象。一、难以避免的浪费在施工现场绑扎主次梁钢筋,特别是绑扎主梁钢筋,都是采取架空绑扎,先将上 In cast-in-place reinforced concrete structures, especially in civil buildings, there are a large number of pre-buried pipelines and primary and secondary beam banding work, but in practice, there is a beam, especially in the middle of the beam concrete cover thickness is difficult to control and PVC Pipeline product protection is not good phenomenon. First, the inevitable waste Binding the main and secondary beam reinforcement at the construction site, in particular, tie the main beam reinforcement, are taken overhead lashing, first on the
