正确答案
优点:节省电能,现场施工可不使用明火,可在易燃、易爆、高空等环境中施工;节省钢材,并不受钢筋焊接性的制约,适合于任何直径的变形钢筋的连接;由于不存在因焊接工艺或材料因素可能产生的脆性接头,接头质量易于控制,便于检查;不受季节气候变化的影响,可以常年施工;施工简便,一般可提高工效3倍,操作人员只需进行一般培训。目前,我国已经开发的钢筋挤压技术主要有两种,即钢筋径向挤压法和钢筋轴向挤压法。
钢筋套筒径向挤压连接适用范围:适用于混凝土结构钢筋直径为16~40mm的Ⅱ、Ⅲ级带肋钢筋的径向挤压连接;使钢筋套筒轴向挤压连接适用范围:与钢筋径向挤压连接相同,适用于同直径或相差一个型号直径的钢筋连接,如Ф25与Ф28,Ф28与Ф32。
